SU905122A1 - Device for ejecting forgings - Google Patents

Description

one

The invention relates to forging press engineering, in particular to multi-stage gary press stamping presses.

A device is known for ejecting forgings from a part of a stamping block of a multi-position mountain of a stamping press articulated with a slider, containing drive pushers and power cylinders of their drive mounted on a slider attached to them at a slider.

A disadvantage of the known device is that all pushers have the same stroke, which reduces the reliability of the press as a whole.

The purpose of the invention is to increase reliability.

The goal is achieved by the fact that the device for ejecting forgings from the part of the block block articulated with the slider, containing drive pushers and articulated power cylinders mounted on the slider attached to the slider, is equipped with two-arm levers mounted on the slider, the rocker springs, on one of the arms of one of the levers and the yoke is made in a groove, this lever and the rocker arm are articulated so that the grooves are aligned, the double-arm lever with the groove of one shoulder is articulated with one of

10 pushers, and the other with one of the rods, while the latter is articulated with one shoulder of the other two shoulders, the second rod is placed in the slots of the two shoulders and the thought box between the third two shoulders and the rocker with the other shoulder articulated with the third pusher.

Fig. 1 shows a multi-position mountain stamping machine with a device for ejection of forgings, general view, fig. 2 - section

A-A in FIG. 1 — on FIG. 3 — section B — B in FIG. 1,

The multi-position die-casting press contains a device 1 for loading workpieces into the die space of a press, a device 2 for transferring forgings from position to position, frame 3, an actuator with a slider t. Slider C contains a device for ejecting forgings from a part of a die block articulated with a slider. This device consists of pushers 5, 6 and 7 and articulated with them mounted on the slider t strong cylinders 8, In addition, the device for pushing is equipped with a two-lever lever 9 that interacts with each other and the rocker arm 10 suspended from x 11 and 12 fixed to each other, rigidly fixed buildings 13 and T, as well as stock 15 and 16,

On the lever 9 and the yoke 10 each grooves are made on one of the shoulders. Lever 9 and rocker 10 are articulated so that the grooves are aligned. The rod 15 is located between the two shoulders lever 17 connected to the actuator power cylinder 8 and the shoulder of the two shoulders lever 9 resting on the spring-loaded pusher 5. The rod 16 is installed in the combined slots of the double arm 9 and the rocker arm 10 mechsdu two arm 18 connected to the force the cylinder 8 of the drive and the second spring-loaded pusher 6, the yoke 8 is installed between the second shoulder of the two shoulders lever 9 and the third spring-loaded pusher 7 "The die unit 19 is attached to the slider k.

The structure works as follows.

Prior to the beginning of the working stroke of the slider k, the device for loading the blanks into the die space supplies the heated workpiece to the first position of the die block 19 and the device 2 for transferring the forgings transports them from one position of the die block 19 to the other. Upon completion of its functions, the operating elements of these devices leave the zone of the die block 719, and the slider k moves down and performs a working stroke.

After the completion of the working stroke, the slider k moves upwards from the bottom dead center and the driving power cylinders 8 are immediately switched on, together with the two shoulders of the levers 17 and 18, independent movement from each other. The lever 17 moves in the vertical direction the rod 15, which acts on the shoulder of the double-arm lever 9. The double-arm lever 9 rotates around a fixed axis

11, actuates the spring-loaded pusher 5 and the rocker 10, which rotates around the fixed axis 12, informs the stroke of the spring-loaded pusher 7, Lever 18 acts on the rod 16, which moves the spring-loaded pusher 6,

Thus, the spring-loaded pushers 5 and 7 make their move by pushing from the upper

half of the die block 19, regardless of the stroke of the sub-pusher of the push rod 6. This allows the forgings to be pushed out of the upper half of the die’s die block after passing the lower dead point by the slider if it is required to have different plunger strokes at the positions When the slider reaches k extreme

The position of the duty cycle is complete and the next one begins.

The invention makes it possible to increase the reliability of the proposed device for pulling out forgings and

the entire press as a whole.
