Abstract

The invention relates to the pressure treatment of metals and can be used in mechanical engineering when forming products with simultaneous quenching from sheet metal. The purpose of the invention is 3 564 quality improvement by uniform cooling of the processed products during the quenching process. During the quenching process, the cooling liquid is supplied both to the lower and upper surfaces of the product 12, and to its end surfaces, i.e. product 12 is cooled uniformly over the entire surface. On the punch 9 is rigidly fixed collector 10, covering the punch 9 and the matrix 2 in the zone of their closure. The collector 10 is in communication with the pipeline 7. On the side surface of the collector 10 are made evenly spaced along its contour of the hole 11, directed into the gap between the matrix 2 and the punch 9. 2 Il. | (L with Nj: O 00 ate ffiusj

Description

The invention relates to die tooling.

The purpose of the invention is to improve the quality by uniformly cooling the processed products during the quenching process.

FIG. 1 shows a stamp., A longitudinal section, in FIG. 2, view A in FIG. one.

The stamp contains the lower fixed plate 1 with the forming matrix 2 installed on it with the choking holes 3. The cavity of the matrix 2 is divided by moving 4 into chambers 5, which are interconnected by channel 6 for supplying coolant through the supply line 7, to the upper movable plate 8 a punch 9 is attached with punching holes 3. On the chip (punch 9 or die 2), a collector 10 is fixed, which covers a stamp in the closing zone of the punch 9 and die 2. The collector 10 is connected to the pipeline 7 and is made with perforating holes 11 The axes of which are directed to the closing zone of the punch 9 and the die 2. The position 12 on the drawings denotes the finished product.

The stamp works as follows.

The heated billet (not shown) is placed on the die 2. When the press slide (not shown) moves down, the die 9 forms the molding 12. Then in the cavity of the die 9 and die 2, cooling fluid is fed through the pipes 7. Through

the cooling holes 3 of the die 2 and the punch 3 coolant washes the upper and lower parts of the product 12. Simultaneously, through the shower holes 11 of the collector 10, the cooling fluid is supplied to the end surfaces of the product 12, and the product 12 is hardened.

The proposed stamp allows almost simultaneously supplying a coolant to all parts of the product, which contributes to uniform cooling of the product and ensures the quality of the products obtained.
