Description

(54) DEVICE FOR REMOVAL OF LARGE-SIZE DETAILS FROM THE STAMP WORKING AREA

FIG. 1 shows the proposed device in the initial position; in fig. 2 - the same in the working position; in fig. 3 is a section along A-A in FIG. 2 in FIG. 4 is a section along BB in FIG. 2j in FIG. b - section of FIG. 2

A device for removing large-sized parts from the working zone of the stamp contains a gripping organ in the form of a series of 1 clip P shaped sections made of non-magnetic material. The clips 1 are hinged at one end on the puller 2 of the upper half 3 of the punch, and the other ends are connected to each other by a cross bar 4, ending with two strips 5 ...

Each plate 5 is placed between RByw m rollers 6 and 7, mounted on a beam 8, mounted on two uprights 9, mounted on a die plate 1O press. The upper limiting roller 6 is located in the lower part of the body 11, rigidly fixed on the beam 8, and has the possibility of only rotational movement. The lower roller 7 is fixed on the be 12, movably installed in the grooves of the housing 11. Between the housing 11 and the bracket; 12, a spring 13 is provided, pressing the roller 7 and the bar 5 interacting with it to the roller 6.

Inside clip 1 by two. pins 14 entering oval holes: ST (W, a bar 15 of a non-magnetic material is suspended (Fig. 2-4). The bar 15 has several axes 16, on which permanent magnets made of cylindrical rollers are mounted on bearings 17 18.

The device works as follows.

After the end of the working stroke of the press, -; when the next part is stamped, the half of the three stamps is returned to rise, and the cage 1 with the stamped part 19, pulled by the magnets 18, is attached. at the opposite ends of the yoke 1, upturning into the rollers 6 and rolling around them, will tilt together with the yoke 1 in a vertical plane, pressing the rollers 7 downward. rolls down on the magnets as n On an inclined plane, it is removed beyond the punch and placed in the foot.

Cetal is removed from the die zone.

the arrival of the press ram in the upper position, which allows it to immediately resume the cycle after its arrival in the indicated position.

In the process of lifting and removing the stamped part, the surface of the lower half of the stamp is free to feed the next workpiece, which makes it possible to carry out automatic stamping of large parts without loss of time.

on their removal.

The device does not limit the dimensions of the workpiece, it has only a mechanical connection with the press, and there are no electrical connections, which simplifies the design

device and increases its reliability in operation.

Formula

the invention

A device for removing large-sized parts; from working; zones of a stamp placed on a press table containing a gripping body, one side hingedly connected to a press ram, and the other resting on rollers mounted on a table, characterized in that, in order to increase labor productivity by combining part removal and workpiece loading , the gripping body is made in the form of a series of U-shaped section cages, in each of which successively mounted on the axes with the possibility of rotation made in the form of cylindrical rollers of the magnet, attracting the part when back During slider holder rigidly coupled together crosspiece, at the ends of which are fixed straps interacting with

spring-loaded rollers moving in a vertical plane.
