Abstract

The stop to the stamp for separation of high-quality hire contains the stop established with a possibility of vertical reciprocating movement under the action of force of the drive, the mechanism of fixing of a stop in the set position in the course of a piece of preparation. The stop is made in the form of rods with guide elements mounted in the guide rails, and spring-loaded by springs. The locking mechanism is made in the form of spring-loaded thrust levers mounted symmetrically about the axis of the rolling and one end cantilevered with axes, and the other, in contact with the corresponding grooves made on the outer surfaces of the stops. The thrust levers are additionally equipped with rollers mounted on axes mounted on thrust levers.

Description

The useful model belongs to the field of engineering, namely 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 stamp 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 stamp body. The disadvantage of such a stop is the impossibility of dividing the graded rolled products into blanks whose length is less than the width of the knife (S.S. Solovtsov. Bezothodnaya razvereka graded rolled products in stamps / S.S. Solovtsov. - M.: Mashinostroenie, 1985. - P.116.)

The closest analogue of the claimed device, chosen as a close analogue, is a stop for the stamp, which contains: the stop itself, installed with the possibility of vertical reciprocating movement in the guides, a mechanism for fixing the stop in a given position during the cutting of the workpiece and a spring-loaded two-armed lever, which, on the one hand, interacts with the lower plate of the stamp, and on the other - with the rolling stock.

Common essential features of the known stop for the die for separating graded rolled products and the one that is claimed are the stop itself, installed with the possibility of vertical reciprocating movement in the guides under the action of the drive force and the mechanism for fixing the stop in a given position during the process of cutting the workpiece.

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. This 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 abutment to the die for separating graded rolled steel by shearing due to freeing the working area in front of the cut workpiece and ensuring the possibility of removing the cut workpiece from the working cavity of the die knives.

The task is solved by the fact that in the stop to the die for dividing the graded rolled steel by a segment with a shear, which contains: the stop itself, installed with the possibility of vertical

From the reciprocating movement under the action of the drive force, the mechanism for fixing the stop in a given position during the process of cutting the workpiece, according to a useful model, the stop is made in the form of rods with guide elements installed in the guide bars and spring-loaded with the help of springs, and the fix mechanism is made in in the form of thrust levers spring-loaded with the help of springs, installed symmetrically with respect to the roll feed axis and one end cantilevered with the help of axles, and the other, with the possibility of contact with the corresponding grooves made on the outer surfaces of the stops, while the thrust levers are additionally equipped with rollers installed on the axles , fixed on thrust levers.

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 technological capabilities of the equipment are deciphered.

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

The stop for the die for separating graded rolled products includes: the stop itself, installed with the possibility of vertical reciprocating movement under the action of the drive force, a mechanism for fixing the stop in a given position during the process of cutting the workpiece, in which the stop is made in the form of rods 1 with guide elements 2 installed in the guide slats Z and spring-loaded with the help of springs 4, and the fixing mechanism is made in the form of spring-loaded with the help of springs 5 thrust levers 6, installed symmetrically with respect to the axis of supply of the rolled product 7 and one end cantilever fixed with the help of axes 8, and the other, with the possibility of contact with corresponding grooves made on the outer surfaces of the rods 1, while the thrust levers would be additionally equipped with rollers 9 installed on the axes 10 fixed on the thrust levers 6.

The abutment to the die for separating graded rolled products works in the following way. The graded rolled steel 7 is fed into the working cavity of the punch knives up to the stop in the rod 1. Under the action of the drive force, the slider separates the rolled steel according to the scheme of the two-support segment by shearing. Two blanks are cut at the same time. The first workpiece 11 is removed from the working area of the stamp "on failure".

The second 12 remains in the working cavity of the knife. At the same time, the slider through the spacers moves the rods together with the guide element 2 to the lower extreme position, in which the rods 1 are fixed. Fixation is carried out due to the fact that the thrust levers 6, under the action of the springs 5, occupy the positions in the corresponding grooves of the rods 1. After cutting the blanks, the slider and the parts of the stamp return to their original position when the press is idling. The cut workpiece 12 is pushed by the force of the rolling stock supply 7 and interacts with the rollers 9, which, together with the thrust levers 5, rotate around the axes 8. Thus, the thrust levers 6 are squeezed out of the grooves and the rods 1, under the action of the springs 4, return to their original position. At the same time, the workpiece 11 enters the container. 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 technological capabilities of the equipment are expanded.
