Metal strip bending machine and bending process using same

Abstract

The invention discloses a metal strip bending machine. The metal strip bending machine comprises a base, two guide columns are supported on the top surface of the base, a mounting plate is arranged onthe guide columns in a sleeving mode, a mounting block is arranged at the top of the mounting plate, a horizontal fixing shaft is arranged on the mounting block, a supporting arm is fixed on the fixing shaft, a cutter rest is fixed at the bottom of the mounting plate, a bending cutter is fixed at the bottom of the cutter rest, a workpiece seat is further fixed on the top surface of the base, theworkpiece seat is located under the bending cutter, a workpiece groove is formed in the top surface of the workpiece seat, a power plate is connected to the side portion of the cutter rest, a mountinggroove is formed in the top of the power plate, a pressing rod is fixed in the mounting groove through a pin shaft, the middle portion of the pressing rod is fixed at the top of the supporting arm through a rotating shaft and can rotate around the rotating shaft, one end of the pressing rod is fixed in the mounting groove, the other end of the pressing rod is a free end, an adjusting mechanism isarranged on the side portion of the mounting plate, and the adjusting mechanism is connected with the power plate.

Description

technical field [0001] The invention mainly relates to the technical field of detection of copper plates and copper strips, in particular to a metal strip bending machine and a bending process for detecting the toughness of copper strips. Background technique [0002] In the prior art, in order to test the toughness of copper plates and copper strips, they need to be bent on a bending machine. The bending angle with the same tool profile can prove that the toughness of the workpiece meets the requirements. However, the bending force of the bending machine in the prior art is completely controlled by the operator, and it is easy to cause excessive force. The bending tool hits the bottom of the workpiece groove violently, which intensifies the tool wear and affects the service life of the bending tool. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention aims to provide a metal strip bending machine and its bending process. ...
