Description

Technical Field

[0001] The utility model belongs to the technical field of blank processing, in particular to a blank bending machine. Background Art

[0002] Blanks refer to raw materials that have not been processed. They can be castings, forgings, or materials obtained by sawing, gas cutting, etc. Blanks are usually made to meet specific process requirements. They need to undergo subsequent processing and treatment to become finished products. During the processing of blanks, a bending machine is usually required to bend the blanks.

[0003] The utility model patent with patent application publication number 202222845650.9 discloses a workpiece processing bending machine, including a box body, an L-shaped plate fixedly installed at the bottom of the fixed plate, and two electric telescopic rods fixedly installed inside the L-shaped plate. The output end of each electric telescopic rod is fixedly connected to a block engaged with a limit gear. By starting the motor, the bidirectional lead screw connected to its output shaft is driven to rotate, so as to control the two sliders on the outside to move in relative or opposite directions, thereby changing the spacing between the two limit plates, and a limit gear is arranged on the outside of the bidirectional lead screw. By starting the electric telescopic rod, the block connected to its output end is fixed to the tooth gap of the limit gear, thereby enhancing the firmness of the bidirectional lead screw and avoiding self-rotation, thereby solving the problem that the adjustment block and the fixed seat are fixed with a first connecting bolt, and the first connecting bolt is prone to rust, which makes the adjustment of the position of the adjustment block more troublesome and inconvenient to operate.

[0004] However, the above device still has shortcomings in actual use. The most obvious one is that it is not convenient to position the blank when the bending machine bends the blank, which easily causes the blank to shift during bending, affecting the bending quality of the blank. For this reason, we propose a blank bending machine. Utility Model Content
