Description

Technical Field

[0001] This application relates to the field of bending machines, and more particularly, to an electro-hydraulic servo numerically controlled bending machine. Background Art

[0002] The essence of a numerically controlled bending machine is a die for bending thin plates. The die consists of a bracket, a workbench, and a clamping plate. By energizing a coil, an attraction force for the pressure plate is generated, thereby completing the clamping of the thin plate between the pressure plate and the base. Since the electromagnetic force clamping method is adopted, the pressure plate is made according to specific workpiece requirements, and the operation is simple.

[0003] The structure of the product can refer to an electro-hydraulic servo numerically controlled bending machine disclosed in Chinese Patent Document No. 201820200584.0, including a bending machine bracket. The upper end of the bending machine bracket is fixedly provided with a cutter fixing bracket by welding. The inner side of the cutter fixing bracket is fixedly provided with a cutter chamber by bolts. Above the cutter chamber is fixedly provided with a cutter motor, and the cutter motor is fixedly provided on one side surface of the cutter fixing bracket by bolts. Inside the cutter chamber is fixedly provided with a cutter, and directly below the cutter is fixedly provided with a concave die block. The structure of the bending machine is improved, and the side wall of the thin plate will not be scratched during the bending process of the thin plate. The excellent product rate is greatly improved during the processing of the thin plate. The top plate structure is redesigned. When the thin plate is bent and then retracts, one end of the top plate can still lift the thin plate, and one end of the thin plate will not slide inward due to a large area on the inner side, effectively avoiding machine shutdown and accelerating production efficiency.

[0004] However, after the workpiece is bent by this patent, manual blanking is required, which is rather troublesome.

[0005] Now, an electro-hydraulic servo numerically controlled bending machine is provided. Summary of the Utility Model

A second servo motor is fixedly connected to the mounting plate, and the output shaft of the second servo motor is fixedly connected to the second threaded rod. And a second limiting component is arranged between the blanking plate and the mounting plate.

[0012] Further, the second limiting component includes a second limiting barrel. A second limiting rod is fixedly connected to the mounting plate, and the second limiting rod is slidably installed on the second limiting barrel.

[0013] Further, a blanking port is opened on the base, and a conveying plate is fixedly connected to the blanking port. The conveying plate is inclined.

[0014] Further, a baffle is fixedly connected to the conveying plate.

[0015] Further, the baffle is provided with two, and the two baffles are symmetrically arranged.

[0016] Further, a protective pad is provided on the conveying plate.
