Node-upright point-selection stamping control method and press machine

Abstract

The invention discloses a node-upright point-selection stamping control method and a press system. The node-upright point-selection stamping control method comprises the following steps: S1, a sliding block moves downwards, so that an upper die is pressed to a lower die; S2, the slide block completes stamping forming processing above a lower dead center; S3, the sliding block continues to slide downwards, and the lower die slides along with the sliding block until the sliding block reaches the lower dead center; and S4, the sliding block moves upwards, and the lower die returns to the position corresponding to a pressure applying point. According to the node-upright point-selection stamping control method and the press machine, a pressure applying point can be selected in the downward moving process of the upper sliding block according to the effect needed by stamping machining, the pressure applying point is not limited to the lower dead center, different stamping process requirements are met, and the applicability is good.

Description

technical field [0001] The invention relates to the technical field of presses, in particular to a control method for node upright point selection stamping and a press. Background technique [0002] The crank slider mechanism is a typical working mechanism of the crank press. This mechanism converts the rotary motion of the press transmission system into the reciprocating linear motion of the slider to realize various stamping processes. [0003] According to the layout characteristics of the motion mechanism, the crank-slider mechanism can generally be divided into two types: node upright and node offset. in the press. The node bias mechanism is mainly used to improve the stress state and motion characteristics of the press, so as to adapt to the process requirements. In the structure of crank slider with node positive bias, the slider has rapid advance characteristics, which is often used in flat forging machines; in the structure of crank slider with node reverse bias, ...

AI Technical Summary

Problems solved by technology

However, the use of the upright mechanism of the crank slider structure press is relatively large, and its pressure point is located at the bottom dead center, and the stamping effect is single.
