Analysis and introduction of the control category of the hose crimping machine

According to the development of the crimping machine and the future trend, the control of the crimping machine can be divided into the following categories: 　　1. The control method adopted in the early days of the country is: visually measure the size and pressure gauge, hand plate reversing valve, to control the operation of the equipment, and equipped with start and stop buttons. 　　2. According to the development of the hydraulic industry, the second-generation tube shrinking machine adopts an electromagnetic reversing valve, replacing the original hand plate reversing valve, and improving the control accuracy of the tube shrinking machine. The reversing valve is controlled by the limit switch (travel switch) or proximity switch to control the operation of the equipment, and is equipped with buttons such as start, stop, tighten, release, inching, semi-automatic, and foot switch. 　　3. Nowadays, all kinds of mechanical control are developing towards precision and digitization, and the control of the shrinking machine is the same. Now a very small number of large domestic manufacturers can configure microcomputer control for the shrinking machine. The operation method is: after starting the equipment, after changing the corresponding mold, directly input the data, and select the corresponding function key to directly withhold. After years of design, development and application, We have formed its own complete and stable series of microcomputer-controlled shrinking machines. 　　 4. The control development trend of various large-scale equipment is to directly connect with the computer for data exchange. The control trend of the shrinking machine is also the same. The future control will be to install the control software in the computer, connect the computer and the shrinking machine to realize data exchange, and then you can conveniently use the computer to control the shrinking machine.       For more information, please visit: http://www.bntflex.com/contact.html

General troubleshooting of the hose crimping machine

It is definitely indispensable for the customers of the hose crimping machine to encounter the tube locking machine failure when using the tube shrinking machine. If you encounter some minor faults, friends who know some mechanical maintenance can probably solve them quickly. But once the hose crimping machine has some major failures, it is not so easy to solve. Then it indicates that the tube locking machine may need to be overhauled. So what should we pay attention to before overhaul What about these elements? 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 main components and assemblies The aging has reached the limit, so the machine should be disassembled, cleaned, inspected and repaired to make its performance reach the standard when leaving the factory. Technical appraisal is required before overhaul of lock pipe machinery It is determined by the technical person in charge of the user unit, and the management, maintenance and driving personnel participate in the pressure, flow, temperature and torque of each part of the machine before disassembly. Check the technical files and operation records, check the fuel and lubricating oil consumption in detail, and make detailed records. Then with the original manufacturer provided The relevant overhaul parameters are compared to determine whether overhaul is required.

Introduction to the performance of the hydraulic oil of the hose crimping machine

Hydraulic oil is the blood of the hose crimping machine equipment, which plays the role of transferring and converting energy. The correct selection of hydraulic oil is closely related to the efficiency and service life of the equipment. Its performance is mainly shown in the following points. Today we will analyze a bit: 　　 1. Proper viscosity, good viscosity-temperature characteristics Viscosity is the first factor to consider when selecting hydraulic oil. Under the same working pressure, if the viscosity is too high, the movement resistance of hydraulic components will increase, and the pipeline pressure drop and power loss will increase; if the viscosity is too low, it will increase the volume loss of the oil drum. The leakage in the assembly increases, and the oil film of the sliding parts becomes thinner, the supporting capacity is reduced, and there is atomization, which overflows from the exhaust port. 　　2, good lubricity (wear resistance) 　　 There are a large number of moving parts in the hydraulic system that need to be lubricated to prevent the wear of the relative moving surface, especially the hydraulic equipment with higher pressure, which requires much higher anti-wear properties of the hydraulic oil. 　　3, good oxidation resistance The hydraulic oil is also oxidized during use. The acidic substances generated after the hydraulic oil is oxidized will increase the corrosiveness of metals, and the sludge deposits produced will block the filter and small gaps, making the equipment work abnormally, so it is required to have good The antioxidant properties. 　　4, good rust and corrosion resistance The hydraulic oil will inevitably come into contact with moisture and air and the acidic substances produced after oxidation will affect the corrosion of the metal valve core and make the hydraulic crimping machine equipment unable to work normally. The hydraulic crimping machine of Kangmai company depends on the frequency of use. It is recommended to thoroughly replace the new and old oil in 3-5 years.

How to judge the quality of the hose crimping machine?

Please pay attention to the following points when judging the quality of the hose when the hose crimping machine is crimping: 　　 1. Check whether the surface is smooth and flat, with bubbles, bumps, sponges, trachoma, etc.; 　　 Second, bend with your hands to see if there are cracks; 　　 3. See whether the steel wire reinforcement layer is arranged regularly; 　　 Fourth, look at the cross section, whether the inner hole and the steel wire layer are round and correct, and whether the inner rubber layer and the outer rubber layer are uniform in thickness; 　　 5. Use nails or a knife to cut the inner and outer rubber to see if it is firm; 　　 6. Use your nose to smell whether the internal and external glue is pungent;

How to expand and crimp the end of the hose

Tube flaring is a forming process to expand the diameter of the end of the tube blank. The shape of the flaring can be tapered or cylindrical. The tube blank enters the deformation zone under the action of axial force, and a cut occurs in the deformation zone. The stretched flaring is plastically deformed, then enters the stable deformation zone, and finally takes shape.   By installing a tubular throttle valve on the main cylinder circuit, the working speed of the main cylinder can be adjusted; the compression cylinder circuit is equipped with a superimposed hydraulic control check valve to ensure the mold Do not loosen during the clamping process; the circuit of the shift cylinder, the limit cylinder, and the axial positioning cylinder are all equipped with superimposed two-way throttle valves, which can adjust the two-way movement speed of the above cylinders. among them The shifting oil cylinder and the limit oil cylinder are used in conjunction with the conversion station, so that the station conversion is convenient and accurate, and the processing quality of the pipe fittings is ensured. The pipe shrinking machine is widely used in the processing and forming of pipe fittings, automobile oil pipes, air pipes, water pipes, air-conditioning pipes and other connecting parts. It is an ideal pipe end forming processing equipment. Including: convex and concave joints, long flat, square, oblique, V-shaped, open elbow, flat elbow, etc. according to product manufacturing into forming molds. The pipe crimping machine is a hydraulic automatic pipe end processing machine controlled by the integrated control touch display screen to expand and shrink the pipe end face under normal conditions. The pipe can be processed by replacing the mold. Pipe end processing such as expanding, shrinking, bulging, upsetting, etc., can be freely determined to use manual, inching or automatic processing according to user needs. The machine tool consists of oil tank, bed, slider, It is composed of main oil cylinder, mold core rod (optional), limit oil cylinder, compression oil cylinder, clamping die, axial positioning oil cylinder, and axial positioning angle iron. Tube necking is the tube blank Molding process with reduced end diameter. The tube blank enters the deformation zone under the action of axial force, produces tangential shrinkage shrinkage plastic deformation in the deformation zone, and then enters the stable zone, and finally forms Reduced end diameter.
