Известный упор недостаточно долговечен .Known stop not durable enough.

Цель изобретени - повышение долговечности упора.The purpose of the invention is to increase the durability of the stop.

Поставленна цель достигаетс тем, что упор к штампу последовательного действи , содержащий токатель, приводимый в движение от верхней плиты штампа, и взаимодействующий с ним шарнирно закрепленный на нижней плите штампа при помощи стойки подпружиненный двуплечий рычаг, несущий на одном из концов опору, взаимодействующую с нижней плитой штампа, и The goal is achieved by the fact that the emphasis is on a sequential stamp that contains a current driven from the top plate of the stamp and interacting with it is pivotally mounted on the lower plate of the stamp using a spring-loaded two shoulders lever, supporting at one of the ends, interacting with the bottom plate stamp and

Claims

FIG. 1 shows an emphasis on a sequential stamp, general view; in fig. 2 shows section A-A in FIG. in fig. 3 view B in FIG. 1. The emphasis on the sequential stamp contains a pusher 1 fixed on the top plate of the stamp (not shown), two shoulders lever 2 with stand 3 fixed on the bottom plate of stand 5. The stand 3 with axis 6 is fixed on resistant 5 End Q of the two shoulders 2 is spring-loaded relative to bottom plate spring 7. At the end of the two shoulders lever 2 installed safety device, made in the form of a lever 8. The lever 8 is installed with the ability to move along the end 5 of the two shoulders lever 2. At the free end of the lever 2 there is a protrusion -5, interacting with the mother 9 scrap matrix 10 of fastening on the lower die plate 9 Processing workpieces is effected punch 115 attached to the upper die plate. At the end of the lever 8, a projection 2 is made, which moves along the end (5 and is spring-loaded against the direction of the matrix 10. At the end (T of the two-armed lever 2, between the lever 8 and the pillar 3), a vertical rod 12 is fixed at one end, which is a support. the rod interacts with the lower plate of the stamp.At the racks 5 a bracket 13 is fixed, at the end of which a screw 14 is screwed with a protrusion 15- On the lever 8 a projection 16 fixed on the side of the bracket 13 is fixed (or made integrally) with the possibility of interaction with the protrusion 15 of the screw 14 . Emphasis to stamp on The following construction works as follows: When the upper plate moves, the punch down punch 11 processes mother 9, and the pusher 1 acts on coax1 and the double-arm lever 2 rotates around axis 6, compressing 7. Upo B lever 8 begins to come out of interaction with material E , and the stop 16 comes under the BbitTyn T5 screw 1 screwed into the bracket 13- Then the stop-out comes out of interaction with the material 9 and the stop 16 interacts with the protrusion 15 of the screw 1. During the course of the upper die plate upward, the punch 11 comes out of interaction with the material 9. a pusher 1 output um from interacting with the end of the two shoulders

2. The double-arm lever 2 under the action of the spring 7 rotates around the axis 6, the protrusion lays on the material 9 and the protrusion 16 continues to interact with the protrusion 15 of the screw It, then move the material 9 to the right, and the protrusion-b enters the hole punched in it. In this case, the double-arm lever 2 rotates around the axis 6, and the protrusion 15 leaves the interaction with the protrusion 16, the lever 8 under the action of the spring moves along the end of the double-arm lever 2. As the material 9 moves further to the right, the protrusion -B interacts with jumpers in the material 9 and moves to the right . The emphasis is rather reliable in work and durable. Claims An emphasis on a sequential stamp containing a pusher driven from the top plate of the stamp and a pivotally attached to it on the bottom plate of the stamp using a spring-loaded double-arm lever, bearing on one of the ends of the support, interacting with the bottom plate of the stamp, and a catcher interacting with the material, fixed with the possibility of moving along the end of the two shoulders lever and spring-loaded in the direction of the working position of the stamp, characterized in that, in order to increase durability stop, it is equipped with a mechanism for fixing the catcher in a predetermined position, including a bracket mounted on the rack, carrying a vertically fixed adjusting screw, periodically interacting with the protrusion, additionally made on the catcher.
