Abstract

The emphasis to the stamp for separation of high-quality hire containing the case established with a possibility of axial and vertical movement on the set distance according to length of the measured preparation cut off, the emphasis. The stop is made in the form of a plate mounted in the guides of the housing with the possibility of horizontal reciprocating motion and spring-loaded by a spring relative to the housing, which contacts the wedge surface with a wedge placed in the guides of the housing with the possibility of vertical reciprocating motion. .

Description

The utility model belongs to the field of engineering, namely, it relates to the technology and equipment of procurement machine-building production and can be used for the production of billets from graded rolled steel for metal cutting and pressure metal processing.

There is a well-known design of a stop to a die for separating graded rolled products, which contains the stop itself, which is installed with the possibility of moving to a given length along the guides fixed on the body of the die. The disadvantage of such a stop is the impossibility of dividing rolled steel into blanks whose length is less than the width of the knife | Solovtsov S.S. Waste-free cutting of graded rolled products in stamps / S.S. Solovtsov. - M.: Mashinostroenieye. 1985. - P. 116.)

The closest analogue of the claimed device, chosen as an analogue, is a stop for a die for cutting graded rolled steel with a differentiated clamp, which contains a stop installed on a carriage, which is fixed at a given distance from the cutting plane on rods located in the racks of the body and interacting with by a slider of the press, and mechanisms for smoothly adjusting the stop to a given length and its axial movement, while it is additionally equipped with a mechanism for adjusting the stop in height, made in the form of a rocker rotating around an axis fixed on the mentioned carriage, spring-loaded relative to the carriage, resting on one shoulder the adjusting screw, placed on the carriage, is made in the form of a tip with a protrusion that fits into the hole of the knife, and the mechanism for axial movement of the stop is made in the form of copiers. attached to the slider of the press and interacting with the mentioned rods, installed with the possibility of their reciprocating movement.

USSR, M. Cl. 826 D7//16. B23 DZ33/10. Stop for a stamp for cutting graded rolled steel with a differentiated clamp / Kyslshyi P.E. Trifonov H.P. - Announced on 06.05.73; Publ. 26.01.73, Bull. Mo 9. - From the village |.

The general essential features of the known stop for the die for separating graded rolled steel and the one claimed are the body of the stop, installed with the possibility of axial and vertical movement for a given distance according to the length of the measuring blank to be cut, and the stop itself.

The known device has significant drawbacks. The stop does not ensure the possibility of removing the cut workpiece from the working area of the punch knives in the case of cutting two workpieces according to the two-stop shear cutting scheme. The design of the stop is very complex and does not ensure the reliability of the stop. It

Zo reduces the technological capabilities of the equipment and reduces the productivity of the separation process.

The basis of the useful model is the task of improving the stop to the die for separating graded rolled products by simplifying the design in which the wedge system is used, increasing the productivity of the separation process and expanding the technological capabilities of the equipment.

The task is solved by the fact that in the abutment to the die for separating graded rolled steel, which contains: a body installed with the possibility of axial and vertical movement to a given distance in accordance with the length of the measuring blank to be cut off, the abutment itself, according to a useful model, the abutment is made in the form of plate installed in the body guides with the possibility of horizontal back-and-forth movement and spring-loaded with the help of a spring relative to the body, which is in contact on the wedge surface with the wedge, which is placed in the body guides with the possibility of vertical back-and-forth movement, the initial position of which is fixed by a screw. In addition to the structure of the stop, a catcher is added, which is placed in the hole of the stop with the possibility of interaction with the hole of the cut workpiece and is spring-loaded using a spring.

The proposed design of the stop to the die for separating graded rolled products provides the possibility of removing the cut blank from the working cavity of the die, the culture of production increases.

The essence of the proposed useful model is explained by the drawing, which shows: - fig. 1 - stop to the stamp for separating graded rolled products (front view); - fig. 2 - stop to the die for separating graded rolled products (top view).

The stop for the die for separating graded rolled products includes: body 1. installed with the possibility of axial and vertical movement for a given distance in accordance with the length of the measuring workpiece 2, which is cut off, from the graded rolled products, the stop, which is made in the form of a plate 3, installed in the guides 4 of the body 1 with the possibility of horizontal reciprocating movement and spring-loaded with the help of spring 5 and pins 6 relative to the body 1, which is in contact on the wedge surface with the wedge 7 installed in the guides of the body 1 with the possibility of vertical reciprocating movement. The starting position of the wedge 7 is fixed using the screw 8.

The abutment to the punch for separating graded rolled products works in the following way. Graded rolled steel 2 is fed into the working cavity of the dies of the die (shown by thin lines), in which the scheme of the two-support segment is implemented by shearing, up to the stop in the plate 3. During the working stroke of the press, the slider (not shown) moves down, cutting two blanks at the same time, one of of which 9 is removed "for failure", and the second 10 remains in the working cavity of the stamp.

At the same time, the slider interacts with the wedge 7, the initial position of which is fixed with the help of the screw 8. Under the action of the slider, the wedge 7 moves vertically in the guides of the body 1 and ensures the horizontal movement of the plate C away from the cut-off workpiece 10, freeing up space in front of it. This allows, at the time of the return of the sliding press to the initial position, to push the cut workpiece 10 with the rod of the graded rolled steel 2 from the working cavity of the punch knives. The cut workpiece 10 falls into the container under the influence of gravity. The work cycle of the stop to the stamp is repeated.

When applying a stop to the die for separating graded rolled products: the possibility of removing the cut blank from the working cavity of the die is provided, the culture of production increases.
