crimping machine with multiple control modes
Time of issue:
2021-02-23
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.
