Abstract

The invention relates to a die tooling and can be used for attaching batch dies to a universal re-assembly unit. The assembly contains a hinged fastener 1 and a tightening bolt 4. Between the head of the bolt 4 and fastener 1, a washer 5 is placed rectangular in plan, coupled with clamping 1 along a spherical surface. The head of the bolt 4 has radial grooves 9, and the end face of the washer 5 has a stepped groove 6. The fixing spring 8 is fixed to the console at one of the steps of the groove 6. The free bent end of the spring 8 is in working position in one of the grooves 9 of the bolt head, preventing it unscrewing under shock loads. When the bolt 4 is tightened, the allen key 11 presses the spring 8 and sinks it into the groove 6, which allows the bolt 4 to be turned. 2 Il.

Description

rig1

The invention relates to cold-stamping tooling and can be used for attaching batch dies in a universal re-assembly unit.

The purpose of the invention is to increase the reliability of fastening.

FIG. 1 shows a mounting unit, a longitudinal section; in fig. 2 is a view A of FIG. one.

The mount consists of a clamp 1, which is connected to the upper plate 2 of the block by means of the axis 3 and the clamp bolt 4. Under the head of the bolt 4 in the slot nest 1 is located rectangular in plan washer 5 with a spherical seating surface. In a rectangular washer 5, a stepped groove 6 is made on its outer end face, in which the lower end of the fixing bent spring 8 is rigidly fixed with a screw 7. The upper end of the fixing spring 8 is located in one of the radial grooves 9 made in the lower part of the bolt head 4. Position 10 marked the top plate of the stamp stamp, position 11 - allen key.

The mount is as follows.

When screwing in the bolt 4 of the clamp, the latter, acting on the washer 5, rotates on the axis 3 the tack 1, which secures the upper plate 10 of the package stamp to the plate 2 blocks. The bolt 4 is screwed in using a socket wrench 11. To turn the bolt 4, the allen key 11 is put on the head of the boate 4 until it touches the washer 5. At the same time, the free end of the fixing spring 8 is pressed and embedded in the stepped groove 6, allowing the bolt 4 to turn. bolt 4 and release it

heads from a socket wrench AND the free end of the locking spring 8 returns to its original position and, falling into one of the grooves 9 of the bolt head 4, locks its position.

The loosening of the upper plate 10 of the package stamp is produced by unscrewing the connecting bolt 4 with an allen key in a similar manner.

Thus, the proposed fastening assembly ensures the fastening of the upper part of the package stamp, preventing the bolt from bending and turning (unscrewing) under shock loads, while enhancing the safety of the stamp.
