Press slide guide

Abstract

The guide device for the slide block of the press includes a slide block, a guide post, a guide sleeve, a fixed seat, a roller and a rolling cage. In the hollow grooves evenly distributed in the circumferential direction of the cage, the inner surface of the roller is in contact with the guide surface of the guide column, and the outer surface of the roller is in contact with the surface of the guide sleeve. The guide sleeve is fixed on the fixing seat, and the fixing seat is installed on the base of the press.

Description

technical field [0001] The invention relates to a sliding block guiding device of a press, in particular to an octagonal prism sliding block guiding device. Background technique [0002] At present, the most widely used slider guide for closed presses is an eight-sided rectangular guide structure, such as image 3 As shown, eight rectangular guide devices 16 are installed on the four corners of the slider 1, through the guiding functions of the eight surfaces at the four corners, the slider is kept reciprocating up and down, and the guiding accuracy is high. But this kind of guiding device is limited by its structure, and the horizontal plane 17 where its guide pair is located is often above the bottom surface of the slider, and the horizontal plane 3 where the strip line is located is below the bottom surface of the slider, as image 3 , Figure 4 As shown, there is a certain distance between the two surfaces. When the slider stamping is tilted by the eccentric load, such ...

But this kind of guiding device is limited by its structure, and the horizontal plane 17 where its guide pair is located is often above the bottom surface of the slider, and the horizontal plane 3 where the strip material line is located is below the bottom surface of the slider, such as image 3 , Figure 4 As shown, there is a certain distance between the two surfaces. When the slider stamping is tilted by the eccentric load, such as Figure 5 The illustrated punch 18 and the die 19, assuming that the inclination angle of the slider is α, the inclination point of the slider is always located on the diagonal of all guides
