Device for monitoring temperature of main shaft bushing of press machine

Abstract

The invention relates to a device for monitoring the temperature of a main shaft bushing of a press machine. Not less than two holes used for installing temperature sensors are uniformly formed on the periphery of the main shaft bushing; the temperature sensors with same parameters are arranged in each hole for installing the temperature sensors; each temperature sensor is connected with a corresponding interface of a PLC programmable controller through respective signal wires; and an output end of the PLC programmable controller is connected with a main control circuit relay of a main control circuit. Thus, the operation of a main shaft and a connecting rod and the operation of the output end and the main control circuit can be realized.

Description

technical field [0001] The invention relates to a monitoring device for a press, in particular to a temperature monitoring device for the main bush of a press. It belongs to the technical field of presses. Background technique [0002] The main bearing bush is an important part of the press. It is in constant relative motion with the crankshaft. At the same time, the motion transmitted by the power system is applied to the working mechanism of the connecting rod slider. The working environment is relatively harsh. Therefore, due to Due to a series of reasons such as poor lubrication, untimely lubrication and poor assembly accuracy, the main bearing bush often burns to death. Once this happens, it will not only cause the equipment to fail to work normally, but even cause serious damage to the equipment. until the serious consequences of scrapping. [0003] At present, for the abnormally high temperature of the main bearing bush of the press, the main preventive measures tak...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a temperature monitoring device for the main bearing bush of a press, which overcomes the method of regular and irregular manual inspection of the existing press. Due to the inevitable existence of human negligence and the influence of other external factors, sometimes Due to the abnormal temperature of the bearing bush, it will often happen that the equipment cannot work normally, and even cause serious damage to the equipment, until it is scrapped.
