Description

one

The invention relates to forging equipment, in particular to crank presses for hot, removable stamping in detachable dies (closed dies).

The purpose of the invention is to increase reliability in operation.

FIG. 1 shows the press, in the initial position, a longitudinal section; in fig. 2 is a section A-A in FIG. I .;

The crank-mount double-acting shtampovaya press contains a frame 1, in the upper part of which there is an actuator consisting of an electric motor and a gear transmission. The crankshaft is shown in the crankshaft 2, mounted in supports 3, brake 4 and clutch 5. with an intermediate plate 7, located in the pressure slider 8 and mounted with the possibility of axial movement. The pressure slider 8 is detachable and consists of a lower part in which a deforming slider 9 is placed, and a cavity with inclined guide grooves 10, and an upper part made in the form of a bolt 11, are made. Both parts are bolted (not shown). In the grooves 10 of the cavity of the pressure slide 8, wedge slides 12 are placed, supported on the intermediate plate 7. The deforming slider 9 has bevels 13 at the end, in which it contacts with the wedge sliders 12. The intermediate plate 7 rests against the cover 11. Brackets 15 are fastened to deforming slider 9 and connected to cylinders of balancers 17 by t-shafts 16 on frame 1. In clamping slider 8 elastic elements 18 are placed, connected to deforming slider 9 through brackets 15.

The crank-mount double-action stamping press works as follows.

In the initial position, both poles are in the upper extreme position. Deforming the slider 9 under the action of leveling I7 and elastic elements 18 squeezes the wedge 12 to the side of the vertical axis of the press. The intermediate plate 7 is resiliently pressed against the cover 11, which bounds it

 About the movement from above.

When the press starts up, brake 4 is engaged with clutch 5 and the movement from the electric motor through a gear train (not shown) is transferred to the crank shaft 2, which rotates in the supports 3 and using the connecting rod 6 through the intermediate plate 7 simultaneously pressing and deforming the slide blocks and moves them down .

20 When the presser slide 8 encounters the workpiece, it stops. In this case, the intermediate plate 7, under the action of the connecting rod 6, continues to move downward, compressing the elastic elements 14 and acting on the wedge sliders 12, which are displaced toward the center along inclined guide slots 10. Moving the wedge sliders 12 causes vertical

30 is a downward movement of the deforming slide 9, which is in contact with the wedge sliders 12 by bevels 13 at its end. From this moment on, the deforming force is transmitted through the wedge slider 12 to the clamping slider 8. The pressing force of the latter is proportional to the deforming force developed by the deforming slider 9.

During the return stroke of the press, the intermediate plate 7 moves up to the stop in a pin. The wedge slider 12 and the deforming slider 9 under the action of the balancers 17 and the elastic elements 18 are returned to the initial position with respect to the pressure slider 8. After that, the two sliders, together with the help of the connecting rod 6, move up to the highest position.
