Closed large-tonnage four-point servo toggle rod stamping device

Abstract

The invention relates to the field of stamping forming machining, and discloses a closed large-tonnage four-point servo toggle rod stamping device. The closed large-tonnage four-point servo toggle rod stamping device comprises a rack, a stamping station is arranged on the rack, and a stamping table driven by a stamping transmission structure to move up and down is arranged above the stamping station. The stamping transmission structure comprises a servo motor fixedly installed on the rack, a transmission gear set in transmission fit with the servo motor and four toggle rod structures in transmission fit with the transmission gear set, the four toggle rod structures are in transmission connection with the stamping table, and riveting points of four fifth transmission rods and the stamping table are distributed in a rectangular shape. By means of the closed large-tonnage four-point servo toggle rod stamping device, the four toggle rods driven by the servo motor are used for driving the stamping table to lift and stamp in a transmission manner, control is precise, meanwhile, the stamping stroke can reach 400 mm, the output stroke is 10-20 mm, a position can be reserved after the stamping table ascends so that an automatic feeding mechanical arm can conduct automatic feeding operation, the overall transmission and stamping pressure is stable, and pressure attenuation of a bottom dead center is small.

Description

technical field [0001] The invention relates to the field of stamping and forming processing, in particular to a closed large-tonnage four-point servo toggle stamping device. Background technique [0002] Large-tonnage stamping machine tools are processing equipment for a variety of processing parts. They have a wide range of uses. At present, stamping machine tools with large tonnages are required, usually through hydraulic pressure, which is also relatively mature. However, compared with servo punching machines, hydraulic pressure has drive accuracy. Insufficient, power loss, large energy loss and other shortcomings. [0003] At present, for large-tonnage servo punching machines, there are few implementations in China. In the servo punching machines that have been realized, there are the following problems: [0004] The stamping stroke is small, and the small stamping stroke is very inconvenient for loading and unloading, and the cramped space cannot realize automatic loa...

AI Technical Summary

Problems solved by technology

[0004] The stamping stroke is small, and the small stamping stroke is very inconvenient for loading and unloading, and the cramped space cannot realize automatic loading and unloading by setting up automation equipment;

[0005] The reduction of stamping pressure is relatively large. At present, the large-tonnage servo punch presses reduce the stamping pressure quickly after a certain stroke.
