Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of gear processing equipment, and particularly relates to a gear processing automatic feeding plate shearing machine. BACKGROUND

[0002] In the process of gear processing, large coiled materials need to be sheared into strip-shaped blanks suitable for stamping or cutting. Direct cutting can be performed using a plate shearing machine in the shearing process, which can avoid direct operation on the original large plate, improve the utilization rate of materials, and meet the processing needs of batch production. Therefore, the automatic feeding plate shearing machine is widely used in the process of gear processing. The existing plate shearing machine for gear processing can basically meet the use needs of daily processing, but there is a lack of a process of treating the surface of the plate before shearing. Hard particles remaining on the plate before shearing can be pressed into the surface of the plate or directly embedded on the cutting edge. At the same time, during the feeding process, the deflection caused by vibration cannot be eliminated. When the long strip-shaped plate is continuously sheared, the deflection amount is accumulated, which increases the unilateral shearing force and easily causes the cracking of the cutting tool during production. Therefore, it is necessary to design the gear processing automatic feeding plate shearing machine. SUMMARY
