Description

one

This invention relates to the blank production of the metal processing industry.

A stamp is known for cutting a bar into blanks, containing a puncheon, a matrix installed in a die-holder, movable and fixed stops, clamps, securing Huie holding material;), and a cut-off blank.

However, for the forced removal of the cut blanks, the installation of devices, conditional, and their strain design is required.

The aim of the invention is to facilitate the removal of the cut pieces.

This is achieved in that the stamp is provided with a stamp located in the case between the lower clamp And the fixed stop supported by an inward support made with a bevel forming a hole with a hole in the die holder for free removal of the cut piece and interacting with the movable stop in a vertical plane.

FIG. 1 shows the proposed stamp; in fig. 2 is a section along the line A-A in FIG. one; in fig. 3 is a section along BB in FIG. one.

The stamp consists of movable 1 and fixed 2 parts connected by columns 3. In the fixed part of the stamp it is spread

matrix holder 4 with matrix 5, spring-loaded punch 6, upper clamp 7, initial blank 8, lower clamp 9, clamping the trimmed blank 10, adjustable die wedge 11 for the matrix, spring-loaded support 12 and fixed support 13.

A working bevel 14 is made at the working end of the support such that when the support is in the lower position, a failure window is formed together with the hole 15 in the die holder. A heat-treated stop 16 is installed in the movable part of the stamp.

The reference billet 10 is placed on the spring-loaded support 12. The bar 8 is fed to the reference billet and the stop 13, after which, when the slide is running, the clamp 7 has a bar, the stop 16 presses it and fixes the clamp on matrix 9 on the clamp 9. Reference blank along the bevel 14 and rolling down through the window 15

in tara.

When the slide is moved up, all parts return to their original position, and then the cycle repeats.
