[0002] Punching and shearing machine is a machine tool equipment which integrates multiple functions such as metal shearing, punching, plate shearing, bending, etc. It can be used to shear plates and round, square, angle and other profiles. When the punching and shearing machine is working, a certain amount of waste will be generated, and a waste collection device is needed to collect the waste.

[0003] A Chinese patent with the publication number CN213671342U discloses a waste collection device for punching equipment. It includes a frame, a receiving platform for receiving waste, and a material box for storing waste. The frame is provided with a transverse movement device for driving the receiving platform to enter or leave the punching equipment, and a discharge device for guiding the waste on the receiving platform into the material box. Guide pillars, guide sleeves and transverse movement cylinders are arranged on the receiving platform. The transverse movement cylinder can drive the receiving platform to enter the lower part of the punching die of the punching equipment to receive the punching waste, and then drive the receiving platform to leave the punching equipment; the turning cylinder can lift the front end of the turning frame, and the punching waste on the receiving platform will slide into the material box behind the frame. The transverse movement cylinder and the turning cylinder are connected to the control system of the punching equipment, which can adapt to the rhythm of the punching equipment, repeat over and over again, and realize the automatic collection of punching waste. The waste stored in the material box can be cleaned and transported in a centralized manner, so as to achieve the effect of easy waste collection, reduce the number of sorting and transportation, and reduce material waste.

[0004] When the existing waste collection device collects the waste generated by the punching and shearing machine, the punched and sheared waste and debris will accumulate in the blanking area, which needs to be cleaned frequently, resulting in poor cleaning convenience; therefore, a punching and shearing machine waste collection device is proposed to address the above problem.
