AI Technical Summary
Technical Problem
The existing hydraulic bracket side guard plates are prone to cracking, poor accuracy and low processing efficiency during bending, and require flame preheating to increase production costs.
Method used
The Q460-grade special steel plate with low carbon and low manganese plus Nb components is adopted. The cutting method is optimized through laser cutting, combined with the three-stage downpression process of the automatic bending workstation, flame preheating is eliminated, and the plasticity of the steel plate and the flatness of the cutting surface are improved.
Benefits of technology
It effectively avoids bending surface cracks on the side guard plate, improves processing accuracy and efficiency, and reduces production costs.

Abstract
The invention provides a hydraulic support integral bending type side guard plate manufacturing method which comprises the specific steps that a steel plate special for a side guard plate is provided, the steel plate special for the side guard plate is cut for the first time according to a drawing, two side guard plate parts to be bent which are spliced together are obtained, and different cutting parameters are adopted for cutting and bending sections and cutting appearance contours; the to-be-bent part of the side protection plate is bent along different bending lines, the bending and pressing process of the obtained bent part is divided into three stages, and each stage corresponds to different bending parameters; the bent part is cut into two parts; and a guide rod seat and a rib plate are respectively welded on each part. The method can prevent the hydraulic support side guard plate from cracking, and the machining efficiency is improved.
