Abstract

The invention relates to press-forging equipment, namely, devices designed to fasten dies having shanks, to a base plate of a press ram and provides increased reliability. The device contains a composite cartridge (П) 3 located in the central groove of the base plate (OP) 1 and used for clamping the shank (X) 2 stamps. Each of the constituent parts of P 3 is connected with an inner surface with the X 2 surface. At OP 1 there is a wedge mechanism 4 clamps P 3, clamps P 3 in the form of screws 9, a spring-loaded ring 6 with radial grooves 7, the inner surface of which is made in the form of a reverse cone and mated with the outer surface of P 3. At OP 1 the clamp of the position of the ring 6 is fixed. OP 1 shank 2 I extends into the working space between the parts P 3. After contact with the punch, the ring 6 begins to move upward, shifting part P 3 before being gripped by X 2. Then the final clamp X 2 is carried out by a wedge mechanism 4. When removing the punch, the operations are performed in reverse order . 1 hp f-ly, 4 ill.

FI.1

The invention relates to press-forging equipment, namely, devices for fastening dies having shanks to a base plate of a press ram.

The aim of the invention is to increase reliability.

FIG. I shows the proposed device, a general view; in fig. 2 - the same plan; pas figs. 3 is a section A-A in FIG. 2; pas figs. 4 is a section BB in FIG. 2

The device contains a composite cartridge 3, which is used for clamping the shank 2 of the stamp, and consists of a clip-on mechanism 4 of the composite cartridge 3 with the force actuator 2 on the base plate 1 of the stamper 2. 5, the retainers of the position of the component parts of the cartridge 3 placed in the central groove of the plate 1 are concentric with the cartridge 3 with the possibility of reciprocating a vertical movement in the vertical direction forgively. the base plate 1 is spring-loaded ko, 6 with radial grooves 7 for clamp clamps 4, the inner surface of which is made in the form of an inverse cone and aligned with the outer surface of the components of the cartridge 3, spread on the supporting The plate 1 is the retainer of the position of the ring 6, while the space of the mating surfaces of the ring 6 i of the cartridge 3 exceeds the conicity of the matching of the 1 surfaces of the shank 2 of the stamp of the cartridge 3 (t. e.,), the central groove of the plate 1 is cylindrical, the plate has radial grooves 8, the locking position of the components of the cartridge 3 is made in the form of a fixed leiHoro on the end of each component of the cartridge 3 with the ability to interact with the corresponding radial groove 8 of the plate 1 of screw 9, the latch position of the ring 6 is made in the form of plates 10 attached to the n, and 1 with the possibility of interaction with the ring 6.

The interacting surfaces of the clips 4 and the slots 7 are made at angles of less than or equal to the angle of self-braking.

The device works as follows.

After installation of the tag with a specially made tapered shank 2 in the weed zone of the press, the slide with the device attached to it is lowered. At the same time, the shank 2 enters the working space between the open components of the cartridge 3. After the contact with the upper die plate, the ring 6 begins to move upwards, shifting the bullet parts of the cartridge 3 along the grooves 8

one towards the other before they pick up the xzss of the tovik 2. Then, the wedge clamps 4 are actuated, which are moved by the actuator 5 towards the cartridge and, interacting with the grooves 7 along the wedge surfaces, clamp the chuck and the shank.

When a die is removed, the operation is performed in reverse order.

The advantage of the proposed design compared to the well-known, in addition to higher reliability, is its greater simplicity and manufacturability, achieved by reducing the accuracy requirements of some surfaces, as well as making slots on a horizontal surface instead of an inclined side in the central groove.
