SU618161A1 - Temporary side stop to die set - Google Patents

Description

The invention relates to the field of high-level processing of metapps and can be used in advanced stamping.

A temporary side stop to the stamp is known, which contains a spring-loaded boot that is fixed in the press with the possibility of reciprocating movement and the travel stop of the running ax jlj

The disadvantage of the known stop is that it is impossible to place it directly under the punch of the stamp and, consequently, the impossibility of using this stop when waste-free sequential stamping.

The chain of the invention is to provide the possibility of using the stop in the case of waste-free sequential punching. By placing the stop under the punch: a punch.

The delivered chain is achieved by the fact that the emphasis is provided with a two-arm lever hinged on the slider, which interacts with it at one end through the spring, and the other with the punch during the operation of the punch.

FIG. 1 shows a general view of the stop installed in the stamp} in FIG. 2 - section A-A of FIG. 1; FIG. 3 is a section & B of FIG. one; in fig. 4 - emphasis in the working position.

Ynop is mounted on the stamp using a puller 1 and a rail 2 attached to it.

The stop contains a slider 3, the stroke of which is limited by screw 4. Slider 3 is returned to its original position by spring 5. On slider 3 is a double-arm lever hinged in the form of plate 6, interacting with the pusher 7, spring-loaded spring 8 and mounted in slider 3. Plate 6 moves along guides, one of which: is the support 9, and the other is the vertical plane of the matrix 10; Plate 6 is located from the cutting edge of the matrix 1O at a distance d. A die 11 is installed in the die for cutting material 12.

When installing the stamped material 12 under the first transition by pressing on

3 ppastinu 6 is introduced into the working position. Plate 6 restricts the advancement of material 12. When working, punch 11 presses plate 6, which descends through topcap 7, squeezes spring 8. When releasing the knob 3, springs 5 and 8 return plate 6 to its original position.

Formupa invention

Temporary side stop to the stamp containing a spring-loaded slider, fixed in the stamp with the possibility of reciprocating movement, tS

and limit the stroke of the popzushka, characterized in that with a chain enabling the use of the anvil in non-waste sequential punching by placing the anvil under the punch of the punch, the anvil is provided with a hinge but fixed on the slider with a two-arm using its end through and another with the punch when working stroke.
