(54) STAMP FOR DRAWING ON HORIZONTALNS-KOBOCHNA MACHINE

one

The invention relates to forging press equipment and can be used when planting products of a wide range.

A stamp for landing on a horizon-forging machine is known, which contains a fixed block matrix and a matrix-insert that is movable in it along the axis of processing and is under the influence of springs.

In order to expand the range of manufactured Products in the proposed stamp, the springs are placed in the fixed block of the matrix, and the stamp is provided with a cross bar located perpendicular to the processing axis, which serves to transfer force to the matrix insert from the springs.

The drawing shows half of the proposed stamp.

The stamp contains a block matrix 1, inside of which is located a movable matrix set 2, connected to a crosspiece 3. The latter is affected by springs 4 located in the slots of the block matrix 1. In addition, the stamp contains a forward movable upset punch 5, a rear fixed punch stop 6 and pins 7 for laying the preform.

The stamp works as follows.

The heated workpiece is placed on the pins 7 so that the rear end of the workpiece touches the rear punch-stop 6. During the working stroke of the machine, the half of the block matrix is closed with the half of the movable insert matrix located in them, and the workpiece falls into the die's stream.

Moving the forward landing punch 5 begins the landing of the front end of the workpiece.

The deformation forces arising during the landing are transmitted to the movable matrix of the insert 2 and, through the traverse 3 connected to it, the forces are transmitted to the springs 4, which hold the sliding matrix in the forward position. Cog-deformation force P {) Evysit force of the springs 4, movable mat together with clamped in it

square insert

billet will begin to DeWind back, and the rear fixed punch-emphasis in the budeg will be produced; the end of the workpiece.

It is the moment when the moving matrix begins to move back and is determined by the force of the springs 4 present in the die. The greater the force of the springs, the greater the deformation of the front end of the workpiece will be made by the forward headplate 5 before the moving back of the movable matrix 2, i.e. the larger in size and more complex in configuration, the front thickening of the POKEEKI can be disembarked.

Subsequently, the forward head punch 5 continues to deform the front end of the workpiece and moves the workpiece together with the movable matrix - insert 2 back, and the stationary rear punch - the stop 6 deforms the rear end of the workpiece, i.e., the two ends of the workpiece are landing simultaneously.

By the end of the working stroke, the forward landing punch is 5; moving matrix insert 2 and moves it to the rear position, completing the deformation of both ends of the forging. Between the block matrix 1 and the movable matrix - an insert 2 in its zagadnom position remains guaranteed races; an even gap of 10-15 mm.

During the return stroke of the machine, the forward landing punch 5 returns to its original position, the movable insertion matrix 2 - together with the crosshead 3 also returns to the initial front position by the force of the springs 4, and this is not the secondary purpose of the spring and considerable effort is not required here. Then, the block matrix 1 is opened, and the forging is ready to be removed from the die.

Subject invention

A stamp for landing on a horizontal-carving machine, containing a stationary block-matrix and accommodated in it a moving matrix, which is movable along the processing axis of the matrix. characterized in that, with nejudv) of expanding the range of manufactured items, the springs are placed in a fixed block matrix, and the stamp is equipped with a pkk-positioned perpendicular to the axis of the traverse, which serves to transfer the inserts from the springs to the axis.
