Description

(54) THE DIRECTING OF THE STRAIGHT-NECK CHAIN OF PRESENTS 1-GH, THE MOST PREDICTIVE PRESS FOR PRODUCTS FROM PLASTICS

one

The invention relates to mechanical engineering, in particular to the construction of guides, mainly presses for plastic products.

There is a known guideline for direct driving movement, comprising articulated, with two pairs of contact surfaces, elements fixed, respectively, on the frame and table t 1 |;

A disadvantage of the known construction of the guides is the incomplete elimination of the influence of thermal deformations on the accuracy of moving the table.

The purpose of the invention is to increase reliability by compensating for thermal deformations.

The goal is achieved by the fact that in a direct-movement directing guide, mainly a press for plastic products containing elements that are fixed on the frame and the table, respectively.

Both pairs of contact surfaces are located in the plane of symmetry of the table.

FIG. 1 shows a device, a general view) in FIG. 2 — node I in FIG. one.

The press table 1 is provided with one part 2 of the guide fixed on its central axis, the working surfaces 3 and 4 of which coincide with the vertical longitudinal axis of the press. A second guide 6 is rigidly attached to the base of the press 5. The press table contains rollers 7 mounted on axles x 8, which move along rails 9. Rollers 7

15 bake the movement of the table in the horizontal plane.

The economic effect of the proposed device in comparison with the known one is ensured at the expense of higher reliability.
