Description

one

The invention relates to the field of forge and press machine building.

Mechanical double-acting presses are known for producing hollow parts from sheet blanks by the method of deep-drawing and pressing. A characteristic feature of these presses is the presence of two sliders (exhaust and pressure), one of which plays the role of a pressure device.

In the known constructions of double-acting mechanical presses, an exhaust slider is located inside a pressure slider having guides on the inner surfaces, but with which the sliding slider 1 is moved.

The disadvantage of this design is the dependence of the accuracy of moving the exhaust slide, and, consequently, the accuracy of the products being forged on the accuracy of the direction of the pressure slide, because it depends on the size of the gaps, i.e. .

The aim of the invention is to create a dual-action mechanical press design, on the one hand, providing accurate guidance of the exhaust slider, regardless of possible distortions of the pressure slider and, on the other hand,} facilitating the manufacture of sliders and their guides compared to known designs.

In the proposed construction, this is achieved due to the fact that the exhaust and pressure sliders are equipped with additional guide plates, while the additional guide plates of the exhaust slide are placed above the guide bars of the pressure slide head and in contact with the collecting bars mounted on the press frame. which are common to

guides of exhaust and pressure sliders. At the same time, nanowires mounted on exhaust and pressure sliders are adjustable.

sliders and their guides.

The press contains a frame 1, in the upper part of which a drive is placed, with elements 2 and 3 of which are connected by an exhaust 4 and a pressing 5 slide blocks. On the posts of the bed 1, there are mounted strap 6, in contact with the additional guide slats 7 of the exhaust slider 4 and with additional guide slats 8 of the pressure slider 5.

During operation of the press, the required gaps in the direction of the exhaust slider 4 and the pressure slider 5 are set independently for each of the sliders by adjusting the guides 7 and 8 of the slats by means of pressure 9 and the length 10 screws provided in each guide.

Thus, the proposed design of a double-action mechanical press provides increased accuracy of the exhaust slider movement, limited by the size of the gaps only in the exhaust slider guides, simplifying the design and reducing the laboriousness of manufacturing the pressure slider by eliminating the processing of sealing surfaces for the exhaust slider guides inside the pressure slider. slider, free access to the mechanisms placed on the exhaust slider, by reducing the height of the pressure slider to determined only by the strength and rigidity of the pressure slide.
