crimping machine with multiple control modes

The hose crimping machine with multiple control modes is a kind of mechanical equipment that presses the plastic pipe and the pipe metal joint together. It includes a hydraulic oil tank, a motor oil pump set, an electromagnetic reversing valve and a connecting pipe. The lock mold components on the body can be crimped on pipes of different sizes by selecting different molds and accurately controlling the diameter of the lock opening. The tube locking machine is divided into manual type and automatic control type. At present, the domestically produced tube locking machine is manually controlled by electrical circuits. The accuracy of manual control is low, and the operation mode is single, and the work efficiency is not high. However, the automatic control type tube locking machine produced abroad has a single control mode, the cost of the controller is high, and the internal hardware structure of the controller cannot be modified, and the writing of the control program is also restricted; at the same time, PLC, travel switches, etc. generally use electromagnetic relays Or the AC contactor indirectly controls the solenoid valve, which is slow in action, which easily causes control delay and affects accuracy. The solenoid valve is an inductive load. Due to the frequent action of the solenoid valve, the contacts of the solenoid relay are prone to adhesion or burnout, which increases the failure rate of the whole machine. In order to solve the problem of material waste, a variety of cutting systems have appeared one after another, all of which use the nesting software to optimize the nesting task data, and then cut the materials according to the nesting results. This kind of nesting software is an isolated software program and does not provide a mechanism for docking with the ERP/CAD system on it. As a result, data needs to be manually input, which is prone to errors and restricts the application. At the same time, independent nesting software lacks and open The overall technical solution of material machinery integration cannot be integrated with CNC equipment in the cutting process to realize manufacturing automation, which affects the efficiency of cutting, and there are some errors that are inconsistent with the layout results. In order to solve the above problems, the present utility model provides a numerical control system for a tube locking machine with low cost, high tube pressing accuracy, and multiple control modes. A numerical control system for a tube locking machine, including a sensor to monitor the piston position, an A/D converter to convert the piston position information, a micro-control unit to control the operation of the system, a control keyboard to input various control information, and display various status information Display unit, pressure pipe valve, back valve, and drive unit that controls the operation of pressure pipe valve and back valve; The input terminals of the micro control unit are respectively connected to the output terminals of the A/D converter and the control keyboard, and the output terminals of the micro control unit are respectively connected to the input terminals of the drive unit and the display unit; the input terminals of the A/D converter and the sensor The output terminal is connected.

Connecting electricity: 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 pointed by the oil pump. 5. Check the ruler: The ruler is located on the front cover of the oil cylinder (see the figure above), 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 cylinder end cover 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 move away from the cylinder end cover flexibly. After being loosened, it will automatically be pressed against the cylinder by the spring force. on. Before starting to withhold, check carefully whether the scale is flexible. Do not fasten the scale to the cylinder with screws, otherwise the scale will be damaged. 6. Pressure adjustment: The maximum pressure of the machine system is 20Mpa, which is adjusted by the overflow valve. Adjust the pressure clockwise to increase, and adjust the pressure counterclockwise to decrease. (Adjusted at the factory, you can adjust by yourself if necessary) 7. Adjustment of mold opening speed: The speed of mold opening speed is controlled by the diverter valve and adjusted clockwise. The mold opening speed is increased, and the mold opening speed is adjusted counterclockwise, and the mold opening speed is slowed down, but too fast mold opening speed will increase the noise. (Adjusted at the factory, you can adjust by yourself if necessary)

The difference between the material casting and forging of the hose crimping machine

 The casting of the hose crimping machine is a metal forming object obtained by various casting methods, that is, the smelted liquid metal is poured into the pre-prepared by casting, injection, suction or other casting methods In a good casting mold, after cooling, sand falling, cleaning and post-treatment are performed to obtain objects with a certain shape, size and performance. There are many classification methods for castings: according to the different metal materials used, they are divided into steel castings, iron castings, copper castings, aluminum castings, magnesium castings, zinc castings, and titanium castings. And each type cast Parts can be further divided into different types according to their chemical composition or metallographic structure. For example, iron castings can be divided into gray iron castings, ductile iron castings, vermicular graphite iron castings, malleable iron castings, alloys Iron castings, etc.; according to the different molding methods, castings can be divided into ordinary sand castings, metal castings, die castings, centrifugal castings, continuous castings, investment castings, ceramics Porcelain castings, electroslag remelting castings, bimetal castings, etc. Among them, ordinary sand castings are the most widely used, accounting for about 80% of all casting output. And non-ferrous metals such as aluminum, magnesium, zinc, etc. Mostly die-casting parts. Due to many factors, castings often have defects such as pores, pinholes, slag inclusions, cracks, and pits. Working cylinders, flanges, pistons, etc. are the main components of the tube shrinking machine. When it works, the pressure is relatively high, so the requirements for the main components are relatively high, and there must be no pores, pinholes, cracks, etc. Forgings are objects in which metal is subjected to pressure to shape the required shape or suitable compression force through plastic deformation. This force is typically achieved through the use of air hammer forging. Forging The process builds a fine grain structure and improves the physical properties of the metal. In the actual use of parts, a correct design can make the particles flow in the direction of the main pressure. For more information about the tube locking machine, please visit: www.bntflex.com
