SU129486A1 - Powerful hydraulic stamping press with frame bed - Google Patents

Description

Production of large-sized parts, in particular, 11 parts, requires large amplifiers from the press equipment, which cannot be provided with known presses due to the insufficient strength of their beds.

A distinctive feature of the described powerful hydraulic forming press with a frame frame, which is made of individual plates, consists of using two rolls and two complete sets for bonding the plates in the corners of the frame frame and, together with the transparent wedges that together form a pre-stressed body joint that prevents the plates from moving relative to one another when the press is in operation, as well as the use of a hydraulic support for the middle frame of the frame.

FIG. 1 shows a press, in obp.1, it is in the form; in fig. 2-unit fastening plates in the corners of the frame frame.

As the power elements of the frame of the press used four frames; assembled from rolled plates. The press is placed on the foundation supports 2 of the four corner edges of the edge. In connection with the fact that during the stamping of short parts, the lower yoke 3 receives deflection, hydraulic supports 4 medium paNt 5 beds on the foundation 6 are used.

In the corners of the frame, in order to perceive the main loads, four cylindrical rolls are installed, of which two scaffolds (Fig. 2) are integral, and two rolls consist of two pairs of cylindrical wedges 8 and 9

The use of stainless steel, IINE, makes it possible to obtain a prestressed fragile joint preventing the frame plates from moving relative to one another and to the work of the press. In addition to the cylindrical palxz. - In the case of external forces directed parallel to the planes of the plates, the corner joints are constricted in the transverse direction with spikes / 0.

The movable TpaBiepca // (Fig. 1), consisting of rolling plates, has four closely connected guide columns 12 which, with their ends, enter the guides 13 hidden on the vertical racks of the power races.

A mechanism is provided for leveling the movable cross head of the press under eccentric loading. (on the figures not on: cauldron), which, when moving the mobile traverse, acts on the valves that supply the angular working cylinders, reducing the force at the end of the traverse opposite to the eccentricity.

A powerful stamping hydraulic press can be used to make large-scale and monolithic parts from alloys used in heavy aircraft.

Preme T invented and

I. A powerful shtampovochny hydraulic press with a bed, consisting of separate p; git, using a device for leveling iodvigil traverse under eccentric loads, which is used in order to increase the strength of the press, used for: fastening of plates in the corners of the frame The beds are two rolls and two “sets of cilidric chinas, together forming a pre-stressed corner joint that prevents plates from moving relative to one another when the press is in operation.

2. Press According to claim 1, characterized in that, with a price. Compensation of the elastic deforming of the lower traverse; a hydraulic support was applied on the foundation base of the base frame.
