Abstract

The invention relates to devices for the mechanization and automation of stamping operations, namely, devices for fastening dies on presses. The purpose of the invention is to increase reliability and reduce metal consumption. The device consists of power cylinders mounted on the die plates with rods, tacks, each of which is designed as an earring, and a rocker arm hinged on it. On the side surfaces of the tacks, guide rails with grooves are rigidly fixed. After the punch is installed on the plate, air is supplied to the power cylinders, thereby ensuring the rotation of the shackle and rocker arm. Stamp fixation occurs. 2 Il.

Description

The invention relates to devices for mechanization and automation of stamping operations, namely, to designs of devices for fastening dies on presses.

The chain of the invention is to increase reliability and reduce metal consumption.

Figure 1 shows a device for fastening dies on presses; figure 2 - view And figure 1.

A device for fastening dies on presses contains power cylinders 2 with rods 3 mounted on the bottom 1 and top (not shown) plates. Each tack is made in the form of an earring 4 and a rocker arm 5 pivotally fixed on the earring 4 by an axis 6, and the rocker is equipped with clamping elements 7 located at the ends of the shoulders of the yoke. The shackle 4 is secured by an axis 8 to the base of the lid 9. The guiding strips 10 are rigidly fixed to the side surfaces of the earrings (tacks) 4, the insert 11 is installed between the guide rails 10 of each tong and is movable relative to the shackle the rod 3 of the power cylinder 2, and the insert 11 is fixed to the guide bars 10.the pin 12, which is inserted into the grooves B of the guide bars 10. Each cylinder 2 is equipped with a sleeve 13, and the rod 3 is spring-loaded relative to the plate 1 by the spring 14. In this case, the wedge The surfaces B of the stem 3 and the inserts 11 are flat.

The device works as follows

In the initial position, the rod 3 is lowered, the stud 4, under the action of a spring (not shown), turns against the owl needle and the lower part of the wedge

the surfaces B of the insert 11 are supported by the lower full wedge surface B of the rod 3, thus preventing the rotation of the rod 3, while the clamping elements 7 of the rocker arms 5 are raised and allow the punch to be installed on the plate 1. Air is supplied to the plate 1 after installing the punch (not shown). into the cavity of the power cylinder 2. The rod 3 moves JQ and acts with its wedge surface B on the wedge surface B of the insert 11. Lastly, turning around the pin 12, self-mounted on the wedge over

The bridge and turns the link 4 and, accordingly, the rocker 5, while fixing the stamp relative to the plate 1. The rocker 5, turning on the axis 6, is also self-clamping relative to the surface of the stamp. Invention Formula A device for fastening dies on presses, containing mounted 0 on die plates, power cylinders with rods, clamps, guide plates with grooves rigidly fixed on the side surfaces of the hooks, inserts installed between the bars of each sticking, connected with them by means of a guide pin located in the said grooves of the bars, and located the possibility of movement relative to the corresponding sticking and interaction with the rod of the corresponding power cylinder along the adjoining surfaces, in contrast to the fact that, in order to improve reliability and metal consumption, each tack is made in the form of an earring and a rocker arm iarnized to it, and the mating surfaces and tack inserts are made flat. 1 duff A Editor IDCHmakova Compiled by V.
