Automatic alarming device of double-station positive mould press

Abstract

An automatic alarming device of a double-station positive mould press is characterized by comprising a programmable logic controller (PLC), a temperature detection module, an analog-to-digital (A / D) conversion module, a driving circuit, a double-station positive mould press control circuit and an alarming device. The output end of the temperature detection module is connected with the input end of the A / D conversion module, the output end of the A / D conversion module is connected with the input end of the PLC, the output end of the PLC is connected with the input end of the driving circuit, and the output end of the driving circuit is respectively connected with the double-station positive mould press control circuit and the alarming device. The automatic alarming device avoids the problems that waste of automobile brake pad is generated in the pressing process of the hot-press process due to the fact that mould working temperature difference exceeds a temperature set range, greatly reduces rejection rate in the production process caused by temperature change, and ensures quality yield of hot press products. The automatic alarming device can timely remind operators to stop a machine for repairing, and is capable of preventing wastes and avoiding waste of manpower and financial resources.

Description

technical field [0001] The invention relates to an alarm device, in particular to an automatic alarm device for a double-station positive molding press. Background technique [0002] Brake pad semi-finished products are made by pressing the brake pad ingredients and steel back for a certain period of time according to the process requirements. Brake materials have high requirements for temperature differences. However, in the process of processing semi-finished brake pads with existing equipment, due to the different types, types and surface areas of molds, different molds are not the same for temperature loss. Therefore, during the processing process, it is easy for temperature fluctuations to exceed the corresponding process requirements. , resulting in waste, a waste of human and financial resources. At present, no effective high-precision temperature control technology has emerged. Contents of the invention [0003] In view of the above deficiencies, the present inv...
