Problems solved by technology

[0003] 1. The working accuracy of the conventional punch slider is determined by the matching accuracy of the guide post. Due to the high manufacturing accuracy of the slider and the guide post, the initial working accuracy can be basically guaranteed. However, the new punch is in use For a period of time or under the condition of improper operation, the precision of the punching machine will be slightly reduced. If high-precision stamping operations are required, the precision of the slider needs to be readjusted. machine operator is unable to complete
[0004] 2. In the manufacturing process of the punching machine, due to the error or error accumulation of the processing accuracy of various components such as sliders and guide columns or the matching accuracy of assembly, each component is processed according to the size of the drawing, and the left and right sides of the slider are directly installed. That is, there is a height difference on both sides, and the parallelism of the slider is not very ideal. In actual assembly, it is necessary to adjust the mold to adjust the parallelism. Second, when using the punching machine to adjust the mold, because the weight of the slider is relatively heavy, when it is necessary to adjust the lift, adjust The friction between the nut and the guide post is relatively large, and the adjustment is quite difficult
[0005] 3. The crank that is most used by the punching machine drives the connecting rod to make the slider move up and down in a straight line to realize the mold splitting and clamping for stamping operations. When the mold is close to clamping, the speed is fast, the time is short, and side slipping is prone to occur, so that the precision of the stamping parts cannot be guaranteed. , so only one product with low precision can be punched, and the overall work efficiency is very low
In addition, there is also a double-knuckle structure designed. Since the connecting rods are respectively connected to the corresponding surfaces of the crankshaft, and the elbow points of the connecting rods do not limit the degree of freedom, when the crankshaft moves, the angle of the single-knuckle structure located on both sides is Asymmetry, resulting in an angle of inclination during the descent of the slider, which impairs the precision of the punched product

Abstract

The invention relates to a high-speed precise punch press, which is provided with an eight-face positioning mechanism, a dual-nut slider structure and a dual-elbow joint transmission structure. The high-speed precise punch press is reasonable in structural design, very simple in operation and high in work efficiency, the adjusting and die adjusting are more convenient, operation personnel can operate the punch press without the need of professional skills of professional punch press maintaining staff, the parallelism of vertical motion and precision of perpendicularity of a slider can be ensured, the precision of the punch press is improved, meanwhile, the anti-fatigue performance of the machine is improved, the work stability is improved, the machine can be normally operated at higher speed, the production time of products is shortened and the cost is saved.

Description

technical field [0001] The invention relates to a high-speed precision punching machine. Background technique [0002] High-speed precision punching machines are widely used in industry, such as the Chinese patent application number 200910095882.3, named high-speed precision punching machine, the Chinese patent application number 200420041448.X, named high-speed precision punching machine, application number 201020100567, named punching machine structure Chinese patents, etc. These high-speed precision presses all have the following deficiencies: [0003] 1. The working accuracy of the conventional punch slider is determined by the matching accuracy of the guide post. Due to the high manufacturing accuracy of the slider and the guide post, the initial working accuracy can be basically guaranteed. However, the new punch is in use For a period of time or under the condition of improper operation, the precision of the punching machine will be slightly reduced. If high-precisi...
