Detailed knowledge of hose crimping machine

The hose crimping machine is widely used in the processing of connecting parts such as air pipes, automobile oil pipes, pipe fittings and water pipes. It is an ideal pipe end forming processing equipment. The processing shapes include: convex, concave, oblong, square, oblique, V-shaped, open elbow, flat elbow, etc. are manufactured into molding molds according to productization. Moreover, the hose crimping machine is used in construction sites, carports, vegetable greenhouses, scaffolding steel pipe manufacturing and other industries to shrink and expand the neck of stainless steel pipes, steel pipes, square pipes, iron pipes, round pipes, etc., a few seconds can be a steel pipe Neck to a suitable size, safe, reliable and easy to use. For some small stainless steel pipes, galvanized pipes can use a single-head liquid compression pipe machine, which is inaccurate and fast. It is simple and convenient to operate. The diameter of the pipe can be adjusted after changing the mold. The compression sleeve of the hose crimping machine is driven by the piston of the oil cylinder to realize a cyclic reciprocating movement, and the spring pressure head fixed on the front plate is continuously changed in tension. Put the assembled connector into the round hole of the spring pressure head, and then turn on the motor to allow the oil pump to supply oil. The reversing valve is switched by controlling the solenoid to drive the cylinder piston to move forward, and the belt is compressed by the compression sleeve. The same taper indenter can successfully achieve the purpose of pressing. **After pressing the button to open the mold, the piston drives the compression sleeve to move in the opposite direction, and the spring pressure head slowly recovers. At this time, the hose joint can be successfully taken out from the crimping machine.

Technical field and description of hydraulic hose crimping machine

Crimping device of hydraulic 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 pipe locking 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. It is equipped with a piston and a piston rod. 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 kind of pipe locking machine is in use, the threaded lock leather is sleeved on the end surface of the pipe to be locked, and this 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, which in turn 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, 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 pipe locking machine can only lock one-way end face and cannot lock large end-face parts, a hydraulic pipe locking machine is provided, which changes the original one-way lock only to Pass lock. The technical solution adopted to solve its technical problems is: it includes a fuselage composed of an oil tank, an electric motor oil pump unit, a program-controlled valve block and connecting pipes, and a locking assembly fixedly assembled on the fuselage. The locking assembly is a cylinder liner. As the main body, a hollow piston is provided 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. An annular sealing return oil chamber is formed between the sealing sleeve and 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 back end of the cylinder liner is equipped with a back end cover , The piston rod is in close contact with the inner surface of the rear end cover, the rear end cover and the inner walls of the piston, piston rod and cylinder liner form an annular sealed process oil chamber, and a process oil passage communicating with the process oil chamber is provided on the back end cover , The return oil passage and the process oil passage communicate with the oil tank in the fuselage through the connecting pipe. The front end of the cylinder liner is equipped with a hollow locking bracket. The locking bracket is evenly distributed with radial guide rails. A sliding block in which the outer slope of the guide rail sliding radially matches the i

How to operate the hose crimping machine

working principle:  The oil pump of the hose crimping machine outputs the hydraulic oil under the power of the motor, and pushes the piston in the hydraulic cylinder to reciprocate, so that the pressure block pushes the mold base, so that the mold base can perform radial contraction movement, and finally realize the module to withhold the hose . When the shrinkage reaches the value set on the control panel, the crimping is automatically stopped, the reversing valve is automatically reversed, and the hydraulic oil enters the lower cavity of the cylinder to drive the upper plate to move upwards. The mold hole is enlarged. Remove the crimped hose That's it. Introduction to the use of the crimping machine: 1. The crimping machine should be crimped 25 times without load during the first use, and observe whether each part can be used normally. 2. When the crimping machine is used in winter, it should be withheld 25 times without load to increase the oil temperature. 3. Next, press the button to open. After the mold base is opened, select the corresponding mold and install it on the mold base according to the specifications of the clamped hose, and adjust the micrometer scale. 4. Place the hose with the joint in the proper position in the crimper head, and crimp the entire length at one time. 5. Press the crimping button for crimping operation until the crimping head stops crimping. 6. After **, take out the crimped hose and use a vernier caliper to check the size of the crimped joint jacket. The parameter table does not meet the scale of the micrometer to be adjusted until the next hose meets the requirements. Precautions for pipe press: 1. When crimping, put the joint in the center of the mold, not on the hexagonal nut. 2. Prevent tools and sundries from entering the crimper head. 3. After the work is completed, the eight mold bases are opened to a large extent, so that the spring can be in an open state and the oil cylinder is also in a pressure relief state to extend the life of the oil seal.

How to effectively maintain the spring system inside the hose crimping machine?

Everyone knows how to use the hose crimping machine, but do you know how to effectively maintain the internal spring system of the hose crimping machine? As we all know, our hose crimping machine is a hydraulic equipment that is used to withhold hydraulic oil pipe joints and fittings. We will use the matched metal joints to apply contraction force to the hydraulic system through the mould of the pipe locking machine, and then withhold the metal joints on the supporting hydraulic Oil pipes and rubber hoses. When the equipment is working, we recommend using No. 32 and No. 46 anti-wear hydraulic oils, and the oil temperature used is within the range of 156 to 70 degrees Celsius. Remember: the oil used is only allowed to be added to the fuel tank after passing strict filtration.   Depending on the cylinder diameter of the crimping machine, the conversion angle is different, so the crimping force produced will also be different. The general mold produced by our factory can produce more than 500T when shrinking. Everyone knows that the basic principle of the hose crimping machine is to use a pipe as a blank, and add an ultra-high pressure liquid inside the pipe while applying an axial thrust to the two ends of the pipe blank for refilling. Under the combined action of these two external forces, the tube blank is plastically deformed, and the tube and the inner wall of the mold cavity are adhered to obtain a hollow part whose shape and accuracy meet the technical requirements.   In terms of maintenance, the hose crimping machine should place the joint in the center of the mold to avoid product damage. After each use, the eight mold bases are opened to the maximum extent, so that the spring can be kept in tension. Open state and can maintain the whole spring system well, and the oil cylinder should also be in a pressure relief state, which can extend the life of the oil seal.

The installation and debugging of BNT50 hose crimping machine need attention

1. The hose crimping machine should be transported by a forklift, and the bottom of the machine should be stressed, and the body is not allowed to tilt. It is strictly forbidden to lift the lock and the ruler. 2. The hose crimping machine must be horizontally fixed on a stable foundation and grounded. 3. Open the casing and add 55-60 liters of No. 46 anti-wear hydraulic oil to the oil tank (the hydraulic oil must be clean, otherwise it will damage the service life of the equipment). Note: If the hydraulic oil is added too little, it will cause the oil temperature to rise too fast and too high, the viscosity of the oil decreases too fast, the oil becomes too thin, and the sealing ring may not seal the oil, resulting in a rise in system pressure Not going up. 4. Connect the power cord to the power supply specified by the machine, and move the motor to observe the direction of rotation. The direction of rotation of the motor should be consistent with the direction indicated by the arrow on the oil pump label. 5. The ruler is located on the front cover of the cylinder and is used to adjust the shrinkage of the crimping sleeve. Adjust clockwise to decrease shrinkage; adjust counterclockwise to increase shrinkage. The ruler seat is pressed against the end surface of the cylinder by the spring force of the three screws. When you pull the ruler by hand (vertical to the end of the cylinder), the ruler seat should be able to leave the cylinder end cover flexibly. After being loosened, it will be automatically compressed on the end of the cylinder by the spring force. Cover. Before starting to withhold, check carefully whether the scale is flexible. Do not fasten the scale to the end cover of the cylinder with screws, otherwise the scale will be damaged. 6. The pressure of the machine system is adjusted by the overflow valve. Adjust the pressure clockwise to increase, and adjust the pressure counterclockwise to decrease (it has been adjusted at the factory, and you can adjust it if necessary, but it must never exceed the rated pressure of the oil pump). 7. The speed of mold opening speed is controlled by the diverter valve and adjusted clockwise to increase the speed of mold opening, and adjust it counterclockwise to slow down the speed of mold opening. However, if the mold opening speed is too fast, the noise will increase (it has been adjusted at the factory You can adjust it if necessary).
