Troubles and troubleshooting of steel pipe crimping machine

Troubles and troubleshooting of steel pipe crimping machine To ensure the permanent mechanical precision and life of the crimping machine, not only high-quality alloy steel materials are selected for the locking organization components, but also a unique heat treatment process is selected. Therefore, the long service life of the pipe press is inseparable from the rationality of material selection, heat treatment, machining, installation and structure. 1. When the machine is used for the first time, it should be withheld for 20 to 30 times, and it can be used after investigating that all parts are normal. The pipe locking machine should be crimped 20-30 times without load in winter to increase the oil temperature. 2. Press the mold opening button to open the mold base. Select the corresponding mold device on the mold base and adjust the scale of the ruler according to the standard of the hose to be crimped. (See the technical parameter reference table for details) 3. Press the mold opening button and take out the crimped hose assembly. Use a vernier caliper to detect the outer diameter of the crimped pipe sleeve. If the crimped diameter does not match the parameter table, fine-tune the scale of the ruler and repeat the above operation until it meets the requirements and stops. 4. Put the rubber tube with the joint in the proper position in the lock, so that the whole length can be crimped at one time. 5. Press the crimping button to perform the crimping operation until the lock head stops crimping. The cylinder piston of the crimping machine is made of integrated fine cast steel to completely solve the cylinder deformation caused by welding, and the product accuracy cannot be reached. 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 steadily and returns quickly, but also does not cause the phenomenon that the mold cannot be opened and locked like a tension spring returning to its position. In addition, the cylinder locking system is designed to run through the front and back, which makes it easy to withhold various special-shaped elbows.

Talking about the correct maintenance method of the hydraulic system of construction machinery

Talking about the correct maintenance method of the hydraulic system of construction machinery The hydraulic system of construction machinery is composed of three parts: hydraulic oil tank, hydraulic pump device and hydraulic control device. The hydraulic oil tank is equipped with an air filter, an oil filter, a liquid level indicator and a cleaning hole. Hydraulic pump devices include different types of hydraulic pumps, drive motors and couplings between them. The hydraulic control device refers to the various valve components and their connecting bodies that make up the hydraulic system. Hydraulic oil plays the role of transmitting pressure, lubricating, cooling, and sealing in the hydraulic oil system. Inappropriate selection of hydraulic oil is the main reason for the early failure and durability of the hydraulic system. The hydraulic oil should be selected according to the brand specified in the random "Instruction Manual". When a substitute oil is needed in special circumstances, the performance should be the same as the original brand. Different brands of hydraulic oil cannot be mixed to prevent chemical reactions and performance changes of the hydraulic oil. Dark brown, milky white, and odorous hydraulic oil is deteriorating oil and cannot be used. 2. Precautions for regular maintenance of the crimping machine 1. When crimping, place the joint in the center of the mold as much as possible, and do not press on the hexagonal nut. 2. Prevent tools and other foreign objects from entering the press head. 3. After each work is completed, the eight mold bases must be opened to the maximum extent, so that the spring can be in an open state and the spring can be maintained, and the oil cylinder is also in a pressure relief state to extend the life of the oil seal. 2.1 250h inspection and maintenance Check the attachments on the filter screen, such as excessive metal powder, which often indicates the wear of the oil pump or the pulling of the oil cylinder. In this regard, it must be diagnosed and taken corresponding measures before it can be turned on. If the filter screen is damaged or dirt accumulated, it should be replaced in time, and the hydraulic oil should be replaced at the same time if necessary. 2.2 500h inspection and maintenance After 500 hours of operation of the construction machinery, the filter element should be replaced regardless of the condition of the filter element, because it is difficult to detect the small damage of the filter element with the naked eye, and the filter element should be replaced appropriately in advance if it is operated at high temperature for a long time.

What is the difference between a pipe smashing machine and a hose crimping machine

What is the difference between a pipe smashing machine and a hose crimping machine The compression sleeve is driven by the cylinder piston to realize reciprocating motion, and continuously compress and loosen the spring pressure head fixed on the front plate. Put the assembled connector into the appropriate position in the middle round hole of the spring pressure head, turn on the motor, drive the oil pump to supply oil, and control the electromagnetic reversing valve to drive the cylinder piston to move forward through the pressure sleeve with the inner cone hole , Press the spring pressure head with the same taper to achieve the purpose of pressing. Press the mold opening button, the piston drives the compression sleeve to move in the opposite direction, and the spring pressure head is restored. At this time, the hose joint can be taken out of the hose crimping machine. The hose crimping machine series is a piece of equipment that the customer group often buys this year, and it has a wide range of applications. Very popular in recent sales. Our models are diverse and the prices are also different. The plunger pump is installed in the oil tank and immersed in the hydraulic oil to achieve the purpose of scientific heat dissipation and mute design. The plunger pump is driven by the motor to output hydraulic oil and push the plunger in the withholding cylinder to move, causing the mold base to shrink radially to realize the mold. Squeeze the outer sleeve of the hose joint. When the shrinkage reaches the predetermined value of the micrometer, the extrusion stops automatically. After the electromagnetic reversing valve changes direction, the plunger in the cylinder moves in the opposite direction, the mold opens, and the hose is crimped. Crimping machine manufacturers are constantly improving processing accuracy. In order to reduce positioning errors and improve processing accuracy, higher precision of fixture manufacturing is required. The precision of positioning holes of high-precision fixtures is as high as ±5μm, and the verticality of fixture supporting surfaces reaches 0.01mm/300mm. The parallelism is as high as 0.01mm/500mm. The accuracy of the crimping machine fixture has been improved to the micron level. In order to meet the needs and economy of different industries, the clamp has different models and different grades of accuracy standards for selection. The hydraulic pressure 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 steadily, but also returns quickly, and there is no phenomenon like spring return that makes the mold not open and locks up. Moreover, the design of the cylinder locking system is through front and back, which is easy to withhold various special-shaped elbows.
