Three-point high speed precision press machine

Abstract

The invention relates to a three-point high speed precision press machine which comprises a motor (1). The motor (1) drives a crankshaft connecting rod system to run through a transmission mechanism. An output end of a crankshaft (6) of the crankshaft connecting rod system drives a dynamic balance block (13) to run through a balance connecting rod (12). A connecting rod (7) of the crankshaft connecting rod system drives guide pillars (9) and a sliding block (10) which is arranged at the lower end of the guide pillar to run through ball bearings (8). The sliding block (10) is provided with three guide pillars (9). The dynamic balance block (13) is arranged in the middle and is arranged on the middle guide pillar (9) through the connecting rod (7). Due to the fact that three plunger type guide pillars are arranged in the sliding block to guide a direction, unbalance loading resistant capability of a machine tool is strong, deformation of the sliding block is reduced by 40 percent under the same blanking condition, and meanwhile, a reverse dynamic device which is arranged on the crankshaft moves up and down, weights of the sliding block and a die are well balanced, whole rigidity of the machine tool is good, accuracy of a bottom dead center of the machine tool is good, and working stability is good.

Description

technical field [0001] The invention relates to a three-point high-speed precision press, in particular to a press. Background technique [0002] In the prior art, in order to adapt to the blanking of more station molds, the slider of the machine tool is continuously widened and lengthened, resulting in an increasing deformation of the slider, which cannot meet the requirements of precision blanking. In order to solve the problem of large deformation of the slider, only strengthening the strength and rigidity of the slider blindly will lead to a large increase in the weight of the slider, which is extremely unfavorable for high-speed punching. Contents of the invention [0003] The purpose of the present invention is to provide a three-point high-speed precision press, which does not use the method of strengthening the slider itself, but adds another guide column between the two guide columns, which can greatly improve the rigidity and strength of the slider without reduci...

Problems solved by technology

[0002] In the existing technology, in order to adapt to the blanking of more station molds, the slider of the machine tool is continuously widened and lengthened, resulting in an increasing deformation of the slider, which cannot meet the requirements of precision blanking

In order to solve the problem of large deformation of the slider, just blindly strengthen the strength of the slider and increase its rigidity, which will lead to a large increase in the weight of the slider, which is extremely unfavorable for high-speed punching
