Control system and control method for safety interlocking of profile steel cogging machine and front pusher bed and back pusher bed

Abstract

The invention discloses a control system and control method for safety interlocking of profile steel cogging machines and the front pusher bed and the back pusher bed. The method comprises the following function modules of an odd-even pass determination unit of cogging machine, a safety interlocking control unit for side guide plates of cogging machine and back pusher bed, a safety interlocking control unit for side guide plates of cogging machine and front pusher bed, and a safety interlocking shielding control unit for side guide plate of front pusher bed of cogging machine and side guide plate of back pusher bed of cogging machine. According to the control system and control method for safety interlocking of profile steel cogging machines and the front pusher bed and the back pusher bed, by the adoption of the above technical scheme, rolled piece heads are prevented from emerging impact the side guide plate of the pusher bed of an outlet side of the cogging machine under the condition that manual position intervention of the side guide plates of the pusher beds of the profile steel cogging machine is enabled; the safety performance and the working reliability are improved.

Description

technical field [0001] The invention belongs to the technical field of metallurgical industrial equipment, and relates to section steel rolling technology. More specifically, the present invention relates to a control method for safety interlocking of a section steel blanking machine and side guide plates of front and rear pusher beds. Background technique [0002] For the large H-beam blanking machine, a pusher bed (Pusher bed, BD machine) needs to be installed on the front and rear working roller tables to realize the movement of the rolled piece between different roll passes, support the biting of the rolled piece, and Straightening of the rolled piece during the rolling process, etc. [0003] The layout of the pusher bed before and after the blanking machine is as follows figure 1 shown. The blanking machine is equipped with a breaking machine roll 5, a main transmission gearbox 12, and a main transmission universal connecting shaft 13; the front and rear pusher beds ...

AI Technical Summary

Problems solved by technology

That is to say, under the condition that the operator concentrates on and carefully operates, the head of the rolled piece will generally not collide with the end of the guide plate on the side of the push bed at the exit side of the blanking machine after it leaves the blanking machine. However, once the operator is careless, or Fatigue leads to too small spacing between the pusher side guide plates on the exit side of the blanking machine, which will inevitably cause the head of the rolled piece to collide with the pusher side guide plate on the exit side of the blanking machine after leaving the blanking machine; when the collision is severe, the pusher will be seriously damaged Bedside guides, which will cause major equipment accidents
