Description

The invention relates to the field of forging and pressing machinery, namely, devices designed to remove the product from a mold or a die of a press.

A pusher to a press is known, which comprises pushers 1 that are mounted on a press ram and can be moved in a vertical direction.

A disadvantage of the known device is the impossibility of its use for pushing products out of multiplace molds and dies of a large area due to possible misalignment and seizure.

The aim of the invention is to expand the operational capabilities of the device.

This goal is achieved by the fact that the pushing device to the press, mainly for pushing out products from large-sized molds and dies of a large area, containing mounted on the press slide with the possibility of moving in the vertical direction, the plungers, is equipped with racks mounted on the press plate of the press mounted on each of the they are movable in the horizontal plane by spring-loaded sliders and articulated with the ability to interact with each other by two roars with protrusions rigidly mounted on the slider of the press with brackets with holes installed in the holes of the brackets with the possibility of movement in the vertical direction and, interacting with the protrusions of the levers and the sliders of the support bars.

In addition, the device. provided with restraints of movement of said levers fixed on racks, while one of each pair of levers fixed on the rack is spring-loaded relative to this rack.

Each rack is equipped with an adjusting finger attached to its free end.

FIG. 1 shows the device in the initial position, general view; in fig. 2 - 5 the same, in intermediate positions.

The device contains mounted on the press slider 1 with the possibility of moving in the vertical direction the pushers 2, located on the press stand 3 of the press plate 3, mounted on each of the latter with the possibility of moving in the horizontal plane the spring-loaded sliders 5 and-hingedly fixed with the possibility of interconnection of the levers 6 - and 7 with protrusions, rigidly fixed on the slider 1 of the press brackets 8 with holes in which

with the ability to move in the vertical direction and interacting with the protrusions of the levers 6 and 7 and the sliders 5, the support plates 9 and 10 are mounted, fixed

on racks 4, limiters 11 of movement of pins 6, while one of each pair of levers fixed on a rack 4 is spring-loaded by means of a spring 12 relative to the latter (in this case lever 6), and on each rack 4 is fixed an adjusting finger 13. In addition, the device contains rigidly connected to the mold ram 1, the sliding plate 14, mounted on the press ram 1 with a puller 15 that can be moved relative to the ram in the vertical direction with the lugs 16 fixed to it and a clamp 17 placed on each stop 16.

The device works as follows.

When the mold (stamps) opens, the slider 1, together with the product, moves upwards, the sliders 5 move, the support bar 10 to the lower position,

the left protrusion of the lever 6 slides freely along the support bar 10. After the protrusion of the anvil 16 touches the right protrusion of the lever 6, the puller 15 with the pusher 2 and the anvil 16 stops, i.e. is held by the lever 6 and the forming plate 14, slider 1,

The brakes strut 9 and 10 continue to move upwards. The pusher 2 emerges from the forming plate 14, i.e., the product is pushed out, and the retainer 17 moves to the lower position. When the left protrusion of the lever 6 comes out of contact with the support bar 10, the puller 15 with the pusher 2 and the stop 16 begins to move further along with other elements, while the lever 6, having overcome the force of the spring 12, retracts the protrusion of the stop 16 to the left. Together with the lever 6, the lever 7 is retracted and the slider is provided (the ability to move up freely. After the slider has moved up, leaving the contact of the stop 16 with the projections of the levers 6 and 7, the spring 12 returns the levers 6 and 7 to its original position. The mold is opened to a predetermined amount.

When the mold is closed (pressed), the slider drops down, the finger 13 enters the opening of the slider 1 (the mold is centered), the slider 5 moves the support bar 9 to the upper position, the left ledge of the lever 6 slides along the support bar 9. After the contact of the ledge stop 16 with a protrusion of the lever 7, the last lever 6 and the support bar 9 keeps the puller 15 from the pusher 2 and the stop 16 from further moving down

before the protrusion of the lever 6 leaves the contact with the support bar 9, the pusher 2 returns to its initial position. The latch 17 occupies the upper position. When the left protrusion of the lever 6 leaves the contact with the support bar 9, the puller 15 with the pusher 2 and the stop 16 begins to move further along with the other elements until the mold is closed. In this case, the levers 6 and 7, having overcome the force of the spring 12, are retracted to the left by the stop 16, and after the contact of the projection of the stop 16 with the protrusions of the levers 6 and 7 (lowering down) the spring 12 returns the levers 6 and 7 to their original position up to the stop in limiter 11.

The pushing device can be made in the form of a single beam (grate) or individual beams (bearing pushers 2) placed between the structural elements (1 and 14) and the protrusions of the supports 16 on two (four) pillars 4 with the elements installed on them (levers 6 and 7, the sliders 5), which makes it possible to pusher a product of any pressing area and at any pressing area.

Compared with the known invention, the present invention allows pushing out any part of the size from the mold (die) and increases the reliability of the device in operation.
