Description

DETAILED DESCRIPTION OF THE INVENTION The subject of the invention is a press with a box-shaped frame with hydraulic, mechanical or other drive, which can be used for various industrial purposes, in particular for plastics work.

Those skilled in the art are aware of presses having frame support structures and are aware of further advances in the design of C-frame presses used in optical applications. Compared to a C-frame press, a press with a frame support structure allows for a considerable increase in the stiffness of the frame and a rigid guidance of the press slide; in a C-frame press - supported from two sides, while Presses with frame support structures are supported from four sides. However, substantial disadvantages of known frame constructions include the difficulty in preparing the surfaces of the basins that guide the internal parts of the press frame, as well as the correspondingly large assemblies used to introduce slide and drive mechanisms inside the press frame. There was a need for windows. For this reason, presses with a frame design are equipped with press slide guides located at their corners, so that the contact surface of the slide guides is considerably restricted. In order to partially eliminate these disadvantages, roll-transverse guides have been used in presses with frame design, but this is difficult due to the amount of pressure transferred and due to the too small contact surface of the guiding elements. It had no effect.

Particular disadvantages are presented by presses with frame support structures using hydraulic drive. That is to say, to collect the difficulty, the hydraulic drive is mounted on the outside of the press frame, sometimes on its top, and attached to said frame by screws. The screw is force-transferred from the main pressure of the press. To partially overcome these disadvantages, box-column design presses were introduced. For example, this can be learned from Borland Patent No. 70015. Such a frame consists of a box shape with one side open and a flat closing plate connected thereto, so that the drive mechanism can be located both in the box shape and in the closing plate. This type of press is characterized by increased rigidity and easy access to the working space of the press, however, as a result of the fact that the dividing plane of the elements of the support device of the press is perpendicular to the working direction of the press slide. The connecting element, usually threaded, transfers the forces resulting from the working pressure of the press. Pressure movements occur in all parting planes of both the frame and the drive of the frame.

The object of the present invention is to overcome the above-mentioned disadvantages of the hitherto known presses of the frame or box-column design of the supporting device and to create such a design of the press, which on the other hand It allows for a high rigidity of the device and on the other hand, by increasing the contact surface of the guide, it allows for improved conditions for guiding the slide inside the frame. The purpose of this is to create two preferably symmetrical parts which after assembly form a closed box shape with a window accessible to the working space of the press, and a dividing plane of said box shape parallel to the direction of movement of the press slide. This is achieved according to the invention by applying a frame consisting of: These elements connecting the image parts of the frame do not transfer the forces resulting from the main pressure of the press. On top of that,
This type of design provides surface treatment and is accessible in a disassembled state with an internal frame of the frame for fixing the guide of the press sly P. Due to the division of the frame in a plane parallel to the direction of the working movement of the slide, it is possible to mount the drive mechanism on the slide and somehow on the side before connecting the parts of the press forming the closed box shape after connection.

As a result, the length of the slide is not similar to previously known press designs, which are limited by assembly reasons or the size of the assembly window. In the press according to the invention, the need to increase the height and lateral dimensions of the press frame due to the reason for assembling the slides was avoided. This not only reduces the dimensions and weight of the press frame, but also considerably increases its stiffness compared to previously known designs.

The frame of the press according to the invention preferably consists of two symmetrical parts 1 and 2, forming a closed box-shaped connection with holes 4 and 5 giving access to the working space of the press. The dividing plane 3 of the image parts 1 and 2 is a press slide 70
parallel to the direction 6 of the working movement. In the dividing plane 3, the image parts 1 and 2 have a groove 8 in which a plate 9 is located, which prevents mutual displacement of the two parts 1 and 2 of the dividing plane 30. Frame flat guides 10 are fixed inside the image parts 1 and 2 and serve to guide the slides 7 of the press, whereby the slides are guided flush to the sides, contrary to previously known designs; Not guided in the corner. At the top the slide 7 is connected with a plate 11 which serves to secure the tool,
It has a discharge hole 12 which serves to discharge the prepared trifles and waste from the inside of the press. Opposite plate 11 a plate 13 is fixed to parts 1 and 2 and serves to fix the upper part of the tool. The slide 70 guide 10a and the upper tool plate 13 covering the section 1 and the 20-minute dividing surface 3 of the frame are at the same time the elements connecting the sections 1 and 2 of the press frame.

Thereby said element does not transfer forces from the main pressure. The slide 7 preferably has slopes 14 at the corners which allow corners 15 of corresponding thickness of parts 1 and 2 of the press frame. This increases the stiffness of the frame and advantageously shifts the loads acting on the frame.

The press according to the invention has a slide P7 10 & a frame fixed to part 1 of the id 10, then the tool plate 13 is fixed, and in part 1 the slide T is mounted with a press drive not shown, then the frame is Mounted with an attached slide, the press drive is mounted so as to be closed by the other part 2 of the frame fixed by pins and screws located in the id 10 and plate 13.

The press according to the invention can be used both as a press with hydraulic drive, mechanical drive and other drives.
