Description

I "

1 part; | a, and also correspond to the size of the finished sheet, to always work as possible with uniform pressure of the press. Above the recess g in the receiver a there is an adjustable matrix, /, which is kept from the displacement by the wedge g in the cylinder a.

The press can be made for simultaneous production of two lCTQBs, for lero versus notches g, h located notches q, q. Above these notches is the second matrix s provided (in its working position with a wedge / t. and t can be interconnected by a crossbar l, while the screw o can serve as a common pulling device for both wedges. The b stamp is guided in the grooves of the vp (Fig. 3). the receiver.

In operation, with the device, one should first place the plates r, and both the plates k, V in the recesses h, r the stamp b, after which the space between the stamp b and the receiver a is greased. The processed material is then introduced either in the molten state and .; silt and in the form of blanks, the coolest value of the hollow space. After that, the matrix f, s is inserted. The space remaining between the front edge, the die and the plate k determines the thickness from 1) of the sheet to be trapped. After the matrix is laid.

it is fixed by wedges / l 4, after which the hydraulically driven piston c, and with it the pressure stamp b, are moved in the direction / direction indicated by the arrow (Fig. 1). Then it is located between the stamp b and the receiver, and the material is compressed and flows out of the hole between the stamp and the die. This flowing material forms the finished sheet. After the stamp b has finished its movement, it is transferred back to its initial position, and V after cleaning the space between receiver a and the pressing stamp b, a new material can be introduced.

The invention; t.
