Ball-screw-driven lever-toggle lever secondary booster presses

Abstract

The invention discloses a ballscrew-driven lever-toggle rod secondary boosting press. Lever-toggle rod two-stage-concatenation boosting mechanisms are adopted in the press, greater output force can be obtained, workpiece contour machining is facilitated, under the condition of certain tonnage of the press, a motor with lower power can be adopted, energy is saved, and cost is reduced; meanwhile, a power system on the press is arranged below a worktable, so the stress condition of a press base is improved, the press base more easily meets strength and stiffness requirements, damping and noise reduction are facilitated, the gravity center of the press is lowered, and the dynamic property of the press is further improved. Compared with the structure of a press in the prior art, the structure size of the press can be greatly reduced, the impact force is great, the work efficiency is high, the energy utilization rate is high, the work noise is low, and the press has excellent overall performance.

Description

technical field [0001] The invention relates to a lever-toggle secondary booster press driven by a ball screw. Background technique [0002] Press is a kind of pressure processing equipment for forming and processing blanks. It is widely used in punching, bending, stretching and extrusion processes, and can directly produce finished or semi-finished products. [0003] At present, the mechanical presses widely used in China are usually driven by ordinary electric motors through clutches, brakes and reducers, etc. to drive crank sliders or screw mechanisms to achieve the required pressure processing tasks. In order to meet the requirements of the processing technology, this kind of traditional press is usually equipped with a flywheel, and the power system is placed above the workbench. The asymmetry of the flywheel structure and the upper placement of the power system will cause the center of gravity of the press to be high. The mechanical properties are poor, the stability ...

AI Technical Summary

Problems solved by technology

In order to meet the requirements of the processing technology, this kind of traditional press is usually equipped with a flywheel, and the power system is placed above the workbench. The asymmetry of the flywheel structure and the upper placement of the power system will cause the center of gravity of the press to be high. The mechanical properties are poor, the stability is poor, and the energy utilization rate is low, the structure size is too large, and the appearance is relatively bulky

In addition, the impact force of the press on the workbench is relatively large, so that the base bears a large impact force and the noise is large. At the same time, the base of the press is required to have high strength and rigidity, so it is also required to a certain extent. The overall size of the press is too large
