Control system and control method of steel punching shear production line

Abstract

The invention discloses a control system and a control method of a steel punching shear production line, capable of ensuring the safe and reliable operation of the steel punching shear production lineby means of the control mode of multi-layered logical judgment. The control system comprises a PLC 1, a server 2, a workstation computer 3, a client computer 4, a proximity position sensor I 5, a proximity position sensor II 6 and a proximity position sensor III 7. The server 2 and the client computer 4 are connected and communicated with the workstation computer 3 through an Ethernet. The PLC 1is communicated with the workstation computer 3 through SPC omm serial communication controls. the PLC 1 serves as a component executing the input or output of external signals; the workstation computer 3 operates the multi-layered logical judgment control programs and sends results to PLC 1, in turn controls a fetching cylinder 8, a swaging cylinder 9, a distribution cylinder 10, a feeding motor11, a pushing motor 12 and an electromagnet used in punching 13 to work according to the operation outcomes of the multi-layered logical judgment.

Description

technical field [0001] The invention relates to a steel blanking production line, in particular to a control system for a rolled bar punching and shearing production line for rod end bearings, and also to a control method for the control system, which belongs to the technical field of stamping equipment. Background technique [0002] At present, the manufacture of rod end bearing forgings in the domestic bearing industry needs to go through the following steps: first cut long rolled bars into short pieces, and then forge them into bearing blanks after being heated by electromagnetic induction. The process of cutting the rolled bar into short pieces is generally completed with a large-tonnage punching machine, but manual feeding and manual sorting of the material heads are required. This work is labor-intensive, and the workers are close to the punching machine when operating, which has great risks. Security risks. Now there is a complete set of blanking equipment with a hig...

Problems solved by technology

In order to ensure the safety and reliability of the operation of the complete set of blanking equipment, the control system needs to carry out multi-layer logic judgment. In the automatic operation state, at the beginning of each cycle, the status of each station should be checked in sequence, and then according to the logic operation As a result, the corresponding action is executed, but using PLC for this kind of multi-layer logic judgment, the programming is cumbersome, the program maintenance is not intuitive, the operation is not reliable, and the PLC control system has a single function, the interface is not friendly, and it is not convenient to set and save the process parameters.
