The worktable consists of a base and a pressure plate. The base is connected to the clamping plate through a hinge. During the processing of metal sheets, it can bend the sheets into different angles.

[0003] In existing technologies, it is impossible to bend a workpiece at multiple angles simultaneously, which affects processing efficiency. Utility Model Content

[0005] The technical solution adopted by this utility model to solve its technical problem is: a multi-angle bending device for bending the body of a freezer, including a base, a sliding column slidably installed in the middle of the base, a placement platform fixedly installed at the upper end of the sliding column, the placement platform for placing workpieces, a side groove provided on the right side of the sliding column, a mounting shaft movably installed in the side groove through a coil spring, an auxiliary bending plate fixedly installed on the mounting shaft, an elbow provided at the lower end of the auxiliary bending plate, a gantry fixedly installed at the upper end of the base, a hydraulic cylinder fixedly installed at the lower end of the gantry, a mounting plate fixedly installed at the telescopic end of the hydraulic cylinder, a connecting column fixedly installed at the lower end of the mounting plate, and an auxiliary bending part provided at the lower end of the connecting column.

[0006] Furthermore, the connecting column has an internal mounting groove, and a first return spring is installed inside the mounting groove. The lower end of the first return spring is fixedly connected to a sliding rod, which is slidably installed inside the mounting groove.

[0007] Furthermore, the lower end of the slide rod is fixedly connected to a support plate, and the lower end of the support plate is in contact with the workpiece.

[0008] Furthermore, a mounting bracket is fixedly installed at the lower end of the base, and several sets of second reset springs are fixedly installed at the upper end of the mounting bracket. A limiting plate is fixedly installed at the upper end of the second reset springs, and a sliding column is fixedly connected at the upper end of the limiting plate.

[0009] Furthermore, a damping rod is provided on the inner side of the second reset spring, the lower end of the damping rod is fixedly installed on the mounting bracket, and the upper end of the damping rod is fixedly installed on the limiting plate.

[0010] Furthermore, a set of fixing plates is provided on the outer sides of both ends of the sliding column. The fixing plates are fixedly installed on the upper end of the base, and the elbow is slidably in contact with the fixing plates.

[0011] The beneficial effects of this utility model are as follows: By placing the workpiece on the placement table and then starting the hydraulic cylinder to press down the connecting column as a whole, the auxiliary bending part contacts the workpiece with the support plate. At this time, the auxiliary bending part continues to press down while the support plate is released from the workpiece and remains stationary, so that the auxiliary bending part bends the left and right sides of the workpiece by 90° and continues to move downward. At this time, the sliding column moves downward so that the bent part contacts the auxiliary bending plate, and then the lower end of the workpiece is bent. In one operation, two parts of the workpiece are bent at the same time, which improves the work efficiency. Attached Figure Description
