Numerical control press machine based on Internet of Things

Abstract

The invention relates to the technical field of press machines, and discloses a numerical control press machine based on the Internet of Things. The numerical control press machine comprises a machine body. Stand columns are arranged on the two sides of the machine body, a lower cross beam is arranged at the bottoms of the stand columns, and a work table is arranged on the top of the lower cross beam. An oil tank is arranged at the top of the macine body. An oil supply pump is arranged in the oil tank. A photoelectric sensor is arranged at the bottom of the machine body, and a first sliding groove is formed in the machine body. A reciprocating screw rod is arranged in the first sliding groove. By controlling the magnetism between a first electromagnet and a second electromagnet and the magnetism between a third electromagnet and a fourth electromagnet, ascending and descending of the reciprocating screw rod can be achieved without controlling forward and reverse rotation of a motor, and the phenomenon that the motor is likely to fail due to frequent start and stop and frequent and repeated forward and reverse rotation of the motor is avoided; and the service life of the motor is prolonged, and the impact frequency of the motor on a power grid is reduced.

Description

technical field [0001] The invention relates to the technical field of presses, in particular to a numerically controlled press based on the Internet of Things. Background technique [0002] As the most advanced electric screw press at present, the CNC press is the best substitute for the friction press. It is widely used in stamping, forging, die forging, punching, etc. in machinery manufacturing, automobiles, tractors and aviation industries, and building materials The dry pressing of tiles and terracotta tiles in the industry, especially the molding and processing of the refractory industry, etc. [0003] The working principle of the CNC press is that the servo control system sends instructions to the motor. When the motor starts, it drives the flywheel to make the screw rotate, and the rotation changes into up and down reciprocating motion to complete the striking action. The striking force, speed, and times are all passed. Digital program precise control. [0004] Wit...

Problems solved by technology

[0004] With the gradual development of modern factories, the method of using the Internet of Things technology to monitor the presses in real time has gradually become popular. When using the Internet of Things technology for monitoring, the presses are often connected to the data server through the client VPN router. Then, after the data processing is completed, the data server sends the processing results to the management computer, which is convenient for people to monitor the working status of the press in real time. In the process of using the data server of the existing management monitoring system, there are signal lines. The plug is not firmly inserted, which will cause looseness, resulting in short circuit of the line and unstable signal, which will affect the use of the management system

[0005] The Chinese invention patent with the application number of 201010261053.0 discloses a numerically controlled press machine, which adopts the traditional electric screw press working mode, controls the repeated forward and reverse rotation of the motor, and then controls the hammer head to move up and down to achieve extrusion. The traditional During the working process of the electric screw press, the motor frequently starts and stops and frequently repeats positive and negative rotations, which makes the motor prone to failure and reduces the service life of the motor
