The bottom plate 101 is provided with a bending assembly, the bending assembly comprises a bending upper die 109 and a bending lower die 127, the bending upper die 109 and the bending lower die 127 are used for bending a plate, an L-shaped lower pressing plate 102 is slidably mounted on the bottom plate 101, a lower pressing motor 106 is fixedly mounted on the bottom plate 101, a lower pressing screw rod 107 is rotatably mounted on the bottom plate 101, an output shaft of the lower pressing motor 106 is fixedly connected with the lower pressing screw rod 107, the lower pressing screw rod 107 and the L-shaped lower pressing plate 102 form a spiral pair, a first mounting bottom plate 108 is fixedly arranged on the lower end face of the L-shaped lower pressing plate 102, a first bolt is symmetrically arranged between the first mounting bottom plate 108 and the bending upper die 109, the first mounting bottom plate 108 is fixedly connected with the bending upper die 109 through a first bolt, a second mounting bottom plate 126 is slidably mounted on the bottom plate 101, a supporting electric cylinder 121 is fixedly connected with the end portion of a piston rod of the supporting electric cylinder 121, the second mounting bottom plate 126 is symmetrically arranged between the second mounting bottom plate 126 and the bending lower die 127, the second mounting bottom plate 126 is fixedly connected with the lower die 127 through a second bolt, the first bolt is convenient to change the upper die 109 and the bending upper die 109.
After the auxiliary assembly finishes welding the stacked plates, the auxiliary plates return to the initial positions, the positioning long plates 111 and the positioning short plates 112 are fixed again, then the abdication motor 118 is started to enable the two support sliding plates 110 to move away from each other, finally the distance between the two support sliding plates 110 is equal to the width of the bending lower die 127, then the support cylinder 121 is started to enable the mounting bottom plate II 126 to move upwards, the bending lower die 127 synchronously moves upwards, finally the upper surface of the bending lower die 127 and the upper surface of the support sliding plates 110 are on the same plane, then the lower piezoelectric motor 106 is started to drive the lower pressing screw 107 to rotate, namely the L-shaped lower pressing plate 102 moves downwards, the mounting bottom plate I108 and the bending upper die 109 synchronously move downwards, and the bending processing of the plates between the positioning long plates 111 and the positioning short plates 112 is realized under the action of the bending upper die 109 and the bending lower die 127.
The working principle is that the plate is placed on a supporting plane, then the position of the plate is adjusted through the positioning component, so that the plate is positioned at the center of the supporting plane, the plate is prevented from being deformed under the action of the positioning long slat 111 and the positioning short slat 112 under the action of the protection component, the plate is subjected to flattening treatment through the flattening component, and after the flattening treatment of the plate is completed, the positioning component is used for adjusting the position of the plate again.
Then the positioning long slat 111 and the positioning short slat 112 return to the initial positions, the plates to be stacked are placed on the plates, the plates to be stacked can be sequentially processed by repeating the steps, after the plates to be stacked are processed, the positioning of the plates is realized through the positioning assembly, the two sides of the plates are pressed and fixed through the auxiliary assembly, the positioning long slat 111 and the positioning short slat 112 return to the initial positions firstly, then the welding gun 156 is used for welding the joint positions of the stacked plates, after the welding of the plates is finished, the positioning long slat 111 and the positioning short slat 112 are fixed again, then the two support sliding plates 110 are moved in the directions away from each other, namely, the bending lower die 127 is moved to the position right below the stacked plates, and then the bending processing of the plates is realized under the action of the bending assembly.
The present invention is not limited to the above-described embodiments, and various modifications made by those skilled in the art from the above-described concepts without inventive effort are within the scope of the present invention.
