Description

Technical Field

[0001] The utility model relates to the technical field of the hemming of anti-theft door panels, and particularly relates to an anti-theft door panel hemming device. Background Art

[0002] An anti-theft door is equipped with an anti-theft lock and can resist abnormal opening under certain conditions within a certain period of time. It is a door with a certain safety protection performance and meeting the corresponding anti-theft safety level, combining anti-theft and safety performance. When producing an anti-theft door, equipment is required to perform hemming processing on the edges of the anti-theft door panel.

[0003] In the application number: CN202221872706.3, this device adjusts the angle of the door panel by installing a positioner. After the support frame moves the anti-theft door panel to the location to be processed, the first cylinder is made to work to push the positioning suction cup to move and position the anti-theft door panel, which can prevent the door panel from shaking. When adjusting the angle of the door panel, the output end of the first motor rotates to drive the turntable to rotate inside the limit frame. When the turntable rotates, it drives the position of the anti-theft door panel through the positioning suction cup, achieving the purpose of adjusting the angle of the anti-theft door panel for processing.

[0004] However, the suction cup used in this device adsorbs and fixes the door panel. Although it can well adsorb the door panel, when separating the door panel from this device, the suction cup instead generates a significant resistance. Moreover, the door panels of anti-theft doors generally have a relatively heavy weight, and it is quite laborious when placing the door panel on the support frame or removing it from the support frame. Therefore, improvements are needed.

[0005] For this reason, we propose an anti-theft door panel hemming device. Content of the Utility Model

[0006] The main purpose of the utility model is to provide an anti-theft door panel hemming device. By arranging a plurality of pulleys on the top surface of the support plate, the anti-theft door can slide in and out when being placed or removed, which is more labor-saving and fast. And through the fixation and adsorption of the electromagnetic suction plate on the anti-theft door panel, the two can be easily separated at any time by power-off, avoiding the separation resistance generated by the suction cup, and effectively solving the problems in the background art.

[0007] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0008] An anti-theft door panel hemming device, including a bottom plate, a sliding cavity is opened inside the bottom plate, the sliding cavity is used for the movable installation of a frame, the frame is arranged in a rectangular frame structure, the inner side of the bottom end of the frame is fixedly connected to the bottom ends of two sliders;
