Description

one

The invention relates to forging machinery, namely, devices designed to mount dies on presses.

The aim of the invention is to improve the reliability of fastening and ease of operation.

Fig. 1 shows a device for fastening dies, a general plan view; figure 2 - section aa in figure 1; on fig.Z - view B in figure 2; figure 4 is a view In figure 2; on fig.Z section GG in figure 2 with a T-shaped clamping sponge; Fig, 6 - the same, with a U-shaped clamping sponge.

The device for fastening the dies contains a tuck 3 installed in the T-slot 1 of the bearing plate 2, with the possibility of stirring along the groove 1 the lower tack 3 with the power cylinder 4 and the bearing part, the hinge attached to the bottom tack with the possibility of turning the upper tack 5 with the supporting part, E1 interacting with the moving parts of the power cylinder 4 and straightened relative to the lower clamp 3 by means of the elastic element 7, while the supporting part of the upper clamp 5 is made as mounted on the axis 8 in the upper clamp 5 s POSSIBILITY removable pivot the clamping jaw 9, the lower sticking 3 is made integral with a supporting part 10 placed in the same vertical plane as the upper jaw 9 5 sticking, the elastic member 7 is formed in vvde placed in the lower clamp arms 3 of disc springs,

The device also comprises a 4 tg 12 12 mounted on a synovial cylinder 11 with an adjusting screw 13 interacting with the free end of the upper sticking 5, a sleeve 14 with guide grooves 15 and a stop screw 16 interacting with the upper sticking 5 mounted on the cup springs 7, pins 17 fixed on the lower tack, placed in guide grooves 15 of the sleeve 14, fixed on the lower tack 3 of the lugs 18, in which axis 19 is placed, on which the upper tack 5 rotates fixed on the upper tack 5 of the handle at 20, pipeline 21 for the supply of energy 076132

the carrier to the power cylinder 4, while the clamping jaw 9 of the upper sticking can be made T-shaped or U-shaped.

5 A device for fastening dies works as follows.

By the handle 20, the device, by a T-shaped protrusion on the supporting part of the lower grip 3, is inserted into

to the T-shaped groove 1 in the bearing plate 2 and move along it up to the stop to the die 22. At the same time, the energy carrier is fed into the cavity of the power cylinder 4 and the device is 5) in the decompressed state. After installing the device to its original position (clamping sponge 9 upper grip is placed above the support surface of the stamp 22, the support

;) The Q part of the lower grip is installed in the T-slot in the same plane with the clamping sponge 9) the energy from cylinder 4 is reset by the force of the disc springs 7 through 25 through the sleeve 14 and the retaining screw 16, the upper clamp 5 extends the axis 19 and the self-adjusting sponge 9j freely seated on axis 8, the stamp 22 is pressed against the die plate 2.

When replacing dies 22 on the press, the release from the clamps is carried out by feeding the energy carrier through conduit 21 to the power cylinders 4. Under the action of the energy carrier, the thrust 12 with the adjusting screw 13 acts on the end of the upper clamp 5 and, overcoming the force of the springs 7, turns the upper sticking 5 on the axis 19 and releases the stamp 22. By the handle 20, the device is moved in slot 1 from the stamp, after which the latter is replaced. After installing a new stamp, the devices for fastening the stamp, depending on the dimensions of the stags, are installed in the corresponding T-slots of the die plate 2 and are fastened. The adjustment of the upper bolt 5 is carried out by turning the key with screws 13 and 16.

The power cylinder 4 can be made hydraulic or pneumatic, in the latter case

55, the rod 11 is mounted on the diaphragm 6.

The choice of the shape of the clamping jaw depends on the size, material, shape of the clamped parts.

The clamping sponge 9 can be made T-shaped and U-shaped.

The proposed device is reliable and convenient in operation, the placement of the support parts of both tacks of the same vertical plane eliminates the occurrence of the overturning moment, the installation of the device by making the bottom sticking one-piece more convenient, adjusting

It is easier and more reliable to produce the upper sticking due to the presence of the adjusting and support screws, as well as the thrust and pins, moreover, in addition, making the supporting part of the upper sticking in the form of a replaceable clamping jaw allows you to make it of a more durable material and quickly replace it. 10 necessary.
