Автоматический упор к вырубным и последовательным штампам работает следующим образом. Упор находится в исходном положении, т.е. упорная деталь 1 упругим элементом 5 поджимается к зеркалу матрицы, а фиксатор 7 находится в свободном положении.Automatic emphasis on punching and sequential dies works as follows. The emphasis is in a starting position, i.e. the thrust piece 1 by the elastic element 5 is pressed against the mirror of the matrix, and the latch 7 is in the free position.

При вводе в штамп заготовки она своей боковой кромкой взаимодействует с выступом 8 фиксатора 7 и поворачивает его Г-образное плечо внутрь Z-образного изгиба 6.упру того элемента 5. При дальнейшей подаче заготовки она упирается в упорную кромку 3 упорной детали 1 и останавливается. Происходит технологическая операция (вырубка-пробивка) , и при обратном ходе ползуна пресса пуансон увлекает за собой заготовку, которая воздейст-³⁵вует на ступень 2 упорной детали. Упорная деталь отклоняется под дей-. ствием заготовки и переводит Z-образный изгиб 6 упругого элемента 5, зафиксировав его над Г-образным плечом фиксатора 7, который удерживается в нужном положении боковой кромкой заготовки. В дальнейшей работе штампа упор участия не принимает.When a workpiece is inserted into the stamp, it interacts with its lateral edge with the protrusion 8 of the retainer 7 and rotates its L-shaped shoulder inside the Z-bend 6. of the elastic element 5. When the workpiece is further fed, it abuts against the stop edge 3 of the thrust part 1 and stops. It occurs technological operation (cutting-punching), and during the return stroke of the slide punch press entrains a workpiece which vozdeyst- ³⁵ exists at stage 2 the thrust piece. The thrust piece deviates under the de-. by the action of the workpiece and translates the Z-shaped bend 6 of the elastic element 5, fixing it over the L-shaped shoulder of the retainer 7, which is held in position by the side edge of the workpiece. In the further work of the stamp, emphasis is not taken.

Claims

The invention relates to cold metal forming and can be used in cutting and successive dies when stamping parts from a strip and a tape. An automatic stop for cutting and consecutive dies is known that contains a lever hinged on one end in a puller that is spring-loaded to the matrix lever, on the free end of which is a protrusion that interacts with the material being processed. Tl 1 The known stop is unreliable in the works. the thrust piece fixed in the groove of the puller, spring-loaded to the matrix by an elastic element fixed at one end on the puller, and the lock of the upper position C 2. This, the emphasis is also unreliable in those and structurally complex. The aim of the invention is to increase the reliability and simplify the design of the stop. The goal is achieved by the fact that in an automatic stop containing a stop piece j installed in the groove of the puller spring-loaded to the matrix by an elastic element fixed at one end on the puller and an upper position lock, the stop piece is fixed on an elastic element, the free end of which is made Z-shaped, the lock is installed with the possibility of rotation around the axis, perpendicular to the mirror of the matrix, and is made in the form of an L-shaped part in contact at one end with an elastic element and having, at the other end, a protrusion Assumption to cooperate with the treated material. FIG. 1 shows an automatic stop in the plan; in fig. 2 is a section along A-A in FIG. one; in FIG. 3 the same, at the time of removal of parts from the punch; FIG., k is a section according to BB, FIG. 2; in fig. 5 is a view of B in FIG. 1. The automatic stop for cutting and sequential dies contains a stop piece 1 having a c-tuck 2 and a stop edge 3 placed in the groove k of the puller and fixed on the elastic element 5, one end 6 of which is made Z-shaped, and the other is fixed on the puller . The stop also contains a retainer 7, which interacts with the elastic element 5 and is installed with a protrusion 8 that is in contact with the material being processed. The automatic stop for punching and successive dies works as follows. The stop is in the initial position, i.e. the anvil part 1 by the elastic element 5 is pressed against the matrix mirror, and the retainer 7 is in the free position. When a blank is inserted into the die, it with its side edge interacts with the protrusion 8 of the retainer 7 and rotates its L-shaped shoulder inside the Z-shaped bend of the 6. elastic element 5. As the blank is further fed, it rests against the abutting edge 3 of the stop part 1 and stops. operation (cutting-punching), and during the return stroke of the press ram, the punch carries along the workpiece, which affects step 2 of the stop piece. The stop piece deflects under the action. The workpiece and translates the Z-shaped bend 6 of the elastic element 5, fixing it over the L-shaped shoulder of the clamp 7, which is held in the desired position by the side edge of the workpiece. In the further work of the stamp the emphasis does not take part. B4 When the stamped workpiece leaves the working area of the stamp, the protrusion 8 is released, and the L-shaped shoulder of the retainer 7 under the action of the elastic element 5 rotates and releases the Z-shaped bend 6 of the elastic element, which presses the abutment piece 1 to the matrix mirror. The stop is ready to go. The use of the automatic support will make it possible to increase the reliability of work and simplify the design of the stamp. Claims of the invention Automatic stop for punching and sequential dies, comprising a stop piece installed in the groove of the puller, spring-loaded to the matrix by an elastic element fixed at one end on the puller, and the upper position lock, which is designed to increase reliability and simplify the design , the stop piece is fixed on the elastic element, its free end is made Z-shaped, the clamp is installed to rotate around an axis, perpendicular to the mirror of the matrix, and made in the form of an L-image Noah part in contact with one end of the elastic element and having at the other end of the protrusion, located with the possibility of interaction with the material being processed.
