Installation and debugging steps of crimping machine

Installation and debugging steps of crimping machine: Many customers are not very clear about the installation and debugging of the pipe buckle machine after purchasing the pipe buckle machine. Below, BNTFLEX will give you a detailed answer.     Handling: The pipe buckle machine is suitable for forklift transportation, and the bottom of the pipe buckle machine is stressed. The pipe buckle machine is strictly forbidden to be inverted. It is specially added to raise the hand to facilitate users who do not have a forklift to carry it at will. It is strictly forbidden to lift the head of the buckle tube, motor and electrical box.     Installation: The pipe crimping machine must be placed horizontally on a stable foundation and grounded.     Oil filling: Open the oil tank cover and add 46 hydraulic oil to the 2/3 position of the oil level gauge.       Electricity connection: Connect the power cord to the power supply specified by the buckle machine, start the motor and observe the direction of rotation. The direction of the motor should be consistent with the direction marked by the motor. If the direction of the motor is inconsistent with the marked direction, please change the position of two of the live wires. Micrometer: used to adjust the shrinkage of the crimping hose, press in more than 1mm counterclockwise half a week, and less than 1mm in clockwise half a week.     Pressure adjustment: The maximum pressure of the buckle machine system is 31.5Mpa, which is adjusted by the overflow valve. The clockwise adjustment pressure increases, and the counterclockwise adjustment pressure decreases (it has been adjusted at the factory, and can be adjusted if necessary). Mold opening speed adjustment: The mold opening speed is controlled by the diverter valve and adjusted clockwise. The opening speed is increased, and the opening speed is adjusted counterclockwise. The opening speed slows down, but too fast opening speed will increase the noise.* *The best value is not more than 10Mpa (it has been adjusted before leaving the factory, you can adjust it yourself if necessary).

Causes of leakage of high pressure hose fitting

Causes of leakage of high pressure hose fitting The application of high-pressure hose is very extensive, and it is used in coal, petroleum and other industries. If the joint of the high-pressure hose leaks, it will bring great losses, so it is necessary to prevent the leakage of the high-pressure hose joint. To prevent leakage of high-pressure hose joints, we must first understand the reasons, so that we can achieve purposeful prevention.       There are several reasons for the leakage of high-pressure hose fitting: "о" ring is aging or deformed to cause leakage; "о" ring is not assembled in place, so that the two planes are connected with uneven pressure or the "о" ring is cut to cause leakage; The “о”-shaped ring is not compacted, and the elastic deformation is insufficient, causing leakage; the “о”-shaped ring is too deep to cause leakage. In this regard, it is necessary to re-select the "о" ring with the same outer diameter and thicker section, or cut or grind the sealing surface with the spigot groove to reduce the depth of the spigot groove to make the "о" The ring has enough elastic deformation (compression should generally be between 0.35-0.65mm). Hose fitting crimping machine     For leaks at pipe fittings using oil-resistant rubber sheet, wool felt, mild steel cardboard, combined sealing gasket or sealant, no matter what material it is, first check whether the seals are damaged, deformed, aging, and rough. , And then take appropriate measures.

crimping machine

crimping machine   The hose crimping machine tightly presses the metal joints with the high-pressure hose through hydraulic machinery and corresponding molds to make high-pressure hoses and fluid connections, referred to as high-pressure hose assembly. High-pressure hose assemblies are widely used in oil fields, coal mines, aerospace, construction machinery, agricultural machinery and other industries.         Driven by the motor, the oil pump outputs hydraulic oil and pushes the plunger in the withholding cylinder to move forward, so that the plunger and the two inner cone sleeves on the front cylinder cover push the mold base with symmetrical cones to shrink radially to realize the module pairing. Withholding of the hose. When the shrinkage reaches the scale setting value, the crimping stops automatically. After the electromagnetic reversing valve changes direction, the hydraulic oil enters the two mold opening cylinders to push the crimping plunger to move in the opposite direction, and the mold seat drives the module to recover under the action of the spring.         The function of the tube locking machine oil seal is simply to seal the oil, and the purpose is to prevent the oil inside the tube locking machine from leaking. The oil is a necessary liquid substance in the system, so the oil seal plays a key role in the tube crimping machine.         **The common oil seal types are divided into single type and assembled type. The output and input ends of the pipe crimping machine have oil seal devices. As the working time is longer, the oil temperature also rises. The oil seal can protect the oil from leaking out, so as to maintain the normal use of oil. The quality and life of the oil are directly related to the quality of the oil seal. On the other hand, it also prevents the waste of resources (oil) and cost increases. Therefore, a good quality oil seal can increase the working time and life of the pipe crimping machine.

Basic knowledge of hose crimping machine

Basic knowledge of hose crimping machine 1. The hose crimping machine adopts the operating principle of dual hydraulic circuits, that is, the advance and retreat of the piston and the opening and contraction of the mold are all driven by the hydraulic power source. It not only moves smoothly and returns quickly, but also does not cause the mold to be locked due to the spring return. Moreover, the design of the cylinder locking system is through front and back, which is easy to withhold various special-shaped elbows. 2. The hydraulic system is composed of a motor, an oil pump, a solenoid valve, a pressure regulating valve and a pressure valve to form a dual hydraulic circuit with forward and retreat movement, and a quick drain valve circuit is added to the dual hydraulic circuit to achieve better The purpose of quick return, and the speed is adjustable, noise and system pressure are reduced. 3. In terms of electrical control system, the control circuit is suitable for PLC circuit, which is easy to check and repair the circuit, easy to maintain, and simple to replace. 4. The tube crimping machine mold and the mold base adopt a non-accumulative error processing technology to ensure that the crimping lines of the product after crimping are evenly spaced, and there is no big or small head phenomenon. 5. For the permanent mechanical precision and life of the pipe locking machine, not only high-quality alloy steel materials are selected for the components of the locking mechanism, but also a unique heat treatment process is adopted. Therefore, the longer service life of the crimping machine is inseparable from the rationality of material selection, heat treatment, machining technology and structure! 6. For the double-column tube crimping machine and C-type tube crimping machine, because it is not convenient to set the dead position, it is necessary to use the numerical control method to control the size of the crimping, such as the products of Metsä Fibre and UNIFLEX. 7. Withholding standard. Theoretical requirements: no head off, no damage to the inner rubber of the hose    It is definitely indispensable for the customers of the tube locking machine to encounter the tube locking machine failure when using the tube locking machine. If you encounter some minor faults, friends who know some mechanical maintenance can solve them quickly, but once there are some major faults in the tube locking machine, it will not be so easy to solve. Then it indicates that the tube locking machine may need to be overhauled. So what elements should we pay attention to before the overhaul? Today we Kangmai will tell you. 1. Technical appraisal before overhaul. At present, some overhauls of pipe locking machines are mostly repairs to restore their performance. After a long period of operation, the aging of each main component and assembly has reached the limit, so all the machines should be fully repaired. Carry out disassembly, cleaning, inspection and repair to make its performance reach the standard when leaving the factory. A technical appraisal is required before the overhaul of the tube-locking machinery, presided over by the technical person in charge of the user unit, management, maintenance and driver participation, and the performance of the pressure, flow, temperature and torque of each part of the machine before disassembly is tested, and Review technical files and operation records, check the consumption of fuel and lubricating oil in detail, and make detailed records. Then compare with the relevant overhaul parameters provided by the original manufacturer to determine whether overhaul is needed.

How to choose high-quality crimping machine

How to choose high-quality crimping machine The products on the market are good and bad, and so are the crimping machines, so how do we buy high-quality crimping machines when we buy crimping machines? Here are three tips for everyone, I hope it will be helpful to everyone . Look: Observe visually whether the hydraulic accessories and electrical components selected by the crimping machine are brand-name products or are produced by regular manufacturers; whether the circuit configuration is regular; whether the design of the oil station pipeline is reasonable; whether there is oil leakage at the connection. If the above passes the visual inspection, you can proceed to the next step. Listen: Turn on the device after connecting it to the power source, and listen to whether the device is running normally. If there is abnormal noise, it is often caused by the installation coaxiality of the motor and the oil pump. Another possibility is caused by the unreasonable selection of the oil pump displacement and pipe diameter, and the quality of the selected motor or oil pump. Not very well caused. Measurement: After **, the main parameters of the equipment are measured Keep the equipment in a dry running state, touch each module block with your hand, and there should be no jitter in the hand, otherwise it will be regarded as a substandard product. Install the equipment on the mold, crimp a sample joint, measure the crimp joint with a caliper or a micrometer, the roundness and taper should be buckled within 0.1mm, which is considered excellent. Mold base hardness and mold hardness are also the key to the normal use of the equipment in the future. Customers can request manufacturers to use a desktop or portable hardness tester to test the mold base or mold. When the hardness of the mold base is lower than Rockwell HRC60 and the mold hardness is lower than Rockwell HRC50, it will affect the withholding quality of the hose. **After the inspection, the eight petals of the mold base of the equipment and the flatness of the mold are inspected. Good equipment will specifically control and adjust these two parameters, while some low-quality equipment does not control the above two parameters. The crimping machine is a combination of various engineering machinery, forming a device that integrates multiple purposes, and realizes one machine with multiple functions.

Technical background and use of hose crimping machine

Technical background and use of hose crimping machine At present, the hose crimping machine produced by domestic manufacturers still adopts the drawings designed in the 1950s, and is made by the principle of four-column horizontal one-way extrusion. The imported hose crimping machine has exquisite materials and flexible operation, but the structure is similar to the domestic one. This type of hose crimping machine is mainly composed of a fuselage under the workbench, a hydraulic cylinder on the workbench and a horizontal four-post bracket. The fuselage mainly includes fuel tanks, valves and connecting pipes. The front and rear ends of the horizontal four-post bracket are fixed There are two sliding plates sleeved on the four pillars in the middle, which can slide in the direction of the pillars. There are connecting screws between the two sliding plates. A hydraulic cylinder is connected to the fixed plate at the rear end of the four-pillar bracket. A piston and a piston rod are provided. The piston divides the hydraulic cylinder into two oil chambers. The cylinder walls of the two oil chambers are respectively provided with inlet and outlet oil passages. The inlet and outlet oil passages are connected to the oil tank in the fuselage through connecting pipes. The front end of the rod is connected to the sliding plate at the front end of the rear fixed plate. The sliding plate at the front end of the sliding plate has a hollow structure. The front end of the sliding plate of the hollow structure is connected with a shrink sleeve. The fixed plate at the front end of the four-post bracket is a hollow structure. The fixed plate at the front end of the four-post bracket is evenly distributed with radial T-shaped guide rails. The T-shaped guide rail is equipped with a sliding block with an outer slope and an inner slope of the shrink sleeve. The sliding block can slide on the T-shaped guide rail to lock the pipeline to be locked. . When this pipe locking machine is in use, the threaded lock leather is sleeved on the end surface of the pipe to be locked, and the end surface is extended from the hollow of the fixed plate at the front end of the four-post bracket. The piston moves forward by the push of oil pressure. The rod drives the sliding plate to slide forward, and the sliding plate drives the sliding plate of the hollow structure to slide in the same direction. The shrink sleeve on the sliding plate of the hollow structure pushes the squeeze slider to radially slide the pipe to be locked on the T-shaped guide rail. Lock, and then take out this pipe fitting. Similarly, put the lock holster with nut on the end of another pipe to lock the other pipe, and then screw the two pipes together, so that during use A loose head accident may occur in Therefore, this pipe locking machine can only perform one-way end-face locking, which is very inconvenient for pipe docking. In addition, because the length of the horizontal four-post bracket of the pipe locking machine is fixed, it cannot lock some large end-face parts with long ends. Close, and the body is heavy and inconvenient to move. In order to solve the shortcomings that the existing hose crimping machine can only crimp one-way end face and cannot crimp large end-face parts, a hydraulic hose crimping machine is provided, which changes the original one-way crimp only into Pass lock. The technical scheme adopted by the present invention to solve its technical problems is: it includes a fuselage composed of an oil tank, a motor oil pump unit, a program-controlled valve block and a connecting pipe, and a locking assembly fixedly assembled on the fuselage. The cylinder liner is the main body. A hollow piston is arranged in the cylinder liner. A sealing sleeve matching the front end of the piston is provided on the inner wall of the front end of the cylinder liner. The sealing sleeve forms an annular sealing return oil cavity between the inner wall of the piston and the cylinder liner. , The cylinder liner wall is provided with a return oil passage communicating with the return oil cavity, the inner cavity of the piston is a bell mouth shape, the piston and the hollow structure piston rod are of unequal diameter structure, and the rear end of the cylinder liner is assembled In the end cover, the piston rod is in close contact with the inner surface of the back end cover.
