(54) STAMP FOR TREATMENT OF STRIP MATERIAL

one

The invention relates to cold metal forming and can be used in dies for processing strip material.

A known stamp for processing strip material contains two stepping knives mounted on the upper plate of the stamp, located on both sides of the working area of the stamp, two stepping stops mounted on the lower plate of the stamp, each of which is located behind one of the stepping knives during the feeding of the material being processed the possibility of adjustment mixing and is equipped with a movement mechanism 1. The disadvantage is that it is impossible to remove the unmeasured residue of the strip material from the working area of the stamp without the use of stepped cuts in the number residue.

The purpose of the invention is to provide the possibility of removing unmeasured Ostatkapolosovogo material from the working area of the stamp without stepping cuts.

This is achieved by the fact that in the proposed design each of the stepper stops is mounted with the possibility of moving.

in the direction perpendicular to the direction of movement of the sheet material, and the mechanism for moving each of the devices is made in the form of a pivotally closed punch on the bottom plate

a lever connected at one end with a step stop; end of the workpiece located at a distance from the working surface of the stepper upra Not less than the feed step and interacting with this end with the material being processed. FIG. 1 shows the proposed stamp in the working position; in fig. 2 is the same at the time of stamping.

The stamp for processing the strip material contains a bottom plate 1 on which guide rails 2 with axles 3 mounted on them are fixed.

On each of the axles 3, there is a double-arm lever 4, with protrusions 5 and 6, at the ends. A groove 7 is made in the protrusion 5. On the bottom plate 1, the stamps are mounted for movement in a direction perpendicular to the direction of movement of the material being processed 8 (strip) two step stops 9 with pins 10, v.% SiK, -5i-ii . g

The spring 12 presses the protrusion 6 to the material of the strip 8.,: The distance between the side 13, the step stops 9 and the protrusions 6 in the inoperative position (Fig. 2) is not less than the step of the material (strip 8). In the working position of the step stops 9 and the protrusions 6 at the time of interaction of the material 8 with the stoppers 13 of the step stops 9 and with the protrusions 6 are the length of the protrusion 6 together with the step stops 9 are not more than the length of the protrusion 6 to the width of the step cutting of the tusks of the holes. material 8:;. .:; Two stepper knives 14, punches 15 and a punch 16 are fixed on the top plate of the stamp, the arrow B shows the direction of movement of material 8 (strips).

When the material 8 is moved in the direction of the arrow B, its front cover acts on bevels And projections 6 and turns the two shoulders levers 4 around the axes 3. The two shoulders levers 4 use the slots 7 of the studs 10 to move the step supports 9 in the direction perpendicular to the mixing direction of the material 8. ..- -...-.,. - - - - .--, ... -. -. -, -. . . .-s; Aij№rti-sri;: rt. ---.-.-- rrv-. Further, the hem of the displacement of material 8 in the direction of arrow B, the front edge abuts against the lateral sides 13 of the stepping stops 9, and the material 8 stops. During the course of the upper stamp punch down, the punches 15 pierce the holes, the punch 16 cuts down the details, and the stepping knives 14 form part of the side edges of the material 8, whose length is equal to the feed pitch. During the course of the top plate of the stamp up punches 15, punch 16. i. stepping knives come out of contact with material 8, are transmitted in the direction of the arrow until the edges 18 interact with the sides 13 stepper stops of the EG - At the end of punching when receiving the unmeasured end (remainder) of material 8, the projections 6 come out of interaction with the material 8, and two shoulders the levers 4 under the action of the springs 12 rotate around the axes 3. In this case, the two shoulders levers 4 move the step stops 9 and allow the material end of the material 8 to pass freely along the guides 2. This eliminates the possibility of punching the oversize punch 16 It prevents the punches 15 and punch 16 from breaking due to the elimination of unilateral lateral forces reaching 0.1-0.2 of the force required for the formula of the invention A stamp for processing strip material containing step knives mounted on the upper plate of the stamp the stamp plate with the possibility of moving step stops, equipped with a mechanism for moving, characterized in that, in order to ensure the possibility of removing the license residue of sheet material from the working area of the stamp, each of the steps The stops are mounted so as to move in the direction perpendicular to the direction of movement of the Sheet material, and the gear of the trans: each of. Shchagovy upbrov is made in the form of a punch of a two-armed lever hinged on the bottom plate, connected at one end with a step support, and at the other end located not less than the feed step from the working surface of the step stop and cooperating with the material to be processed.
