[0002] A bending machine is a machine that can bend thin sheet metal parts. Its structure mainly includes a bracket, a workbench and a clamping plate. The workbench is placed on the bracket. The workbench is composed of a base and a pressure plate. The sheet metal part is placed at the bottom of the pressure plate, and the pressure plate is driven down by a movable seat to achieve fast and accurate bending processing of the sheet metal part.

[0003] In the existing sheet metal auxiliary bending machine, the sheet metal is placed between the pressing plate and the bending seat, and the pressing plate is moved downward to perform extrusion bending processing on the sheet metal. However, there are the following defects:

[0004] (1) When the existing sheet metal auxiliary bending machine is in use, after the bending process is completed, the sheet metal on the bending seat needs to be manually removed. However, during the material removal process, since the pressure plate is suspended on the top, when an equipment failure occurs, the pressure plate suddenly moves down, which can easily cause injuries to workers. For this reason, we propose a sheet metal auxiliary bending machine with a protective structure. Utility Model Content

[0014] (1) Through the designed rotating frame, support frame, push rod, slide cylinder and magnetic plate, the support frame is installed on the machine base by flipping on the ring frame. After the bending process is completed, the pressure plate is lifted. When the sheet metal bending parts need to be removed from the bending seat manually, the support frame is flipped upward so that it is vertically at the bottom of the pressure plate. The side magnetic plate is adsorbed and fixed in position. The support frame is at the bottom of the pressure plate to support the pressure plate to avoid the pressure plate from moving down and causing harm to the workers during the material collection process, thereby playing a protective role. Through the designed retaining groove and block, the push rod is limited to slide and prevented from detaching from the slide cylinder. Through the designed top spring, the top spring exerts an elastic squeezing effect on the push rod to ensure that when the end of the push rod and the support frame are in contact and adsorbed, the push rod does not slide back and is not easy to be adsorbed and connected.
