A stamp for non-waste stamping, containing punches and dies, including a counterclockwise side knife with an emphasis, characterized in that the punches are stepwise in adjacent rows, while their cutting edges are parallel to each other along the strip, and the upper counterclamping plane with an emphasis is made above the side plane a knife.

Description

 Stamp for non-waste strains.

The inventive utility model relates to the processing of metals by pressure, in particular to the design of dies, to obtain parts from sheet material and can be used in various fields of technology, in particular mechanical engineering. “; / An analogue of a utility model of the same purpose, character, and zoom in with a combination of 1 signs. Services: b; Troy for parallel stamping of parts from sheet material, its use USSR And, M.kl V21D 28/00, Sh1D 35/00. The design of the known solution contains a matrix fixed to the bottom plate, on which are attached above paBJMTOipe hshanki, which are countercurrent from two sides. In one of the slats, a protrusion is made for using the feed material into it. In the upper part of the device, a working tool is mounted, consisting of six punches for cutting parts installed in at least one row parallel to the direction of the underfloor material, and a means for supplying material to the back step is a side step knife, the length of which is 6 ; and, is the cutting step. The punches in a row are arranged in two groups, three nuances in a group. In the group, the punches are placed at an equal distance of 2 a relative to each other, and the distance between the outer end: nearby punches of different groups are 3 a.

MateriaSl is fed up to yiiopa in a protrusion located in one vertical plane with the front 4-jaw of a stepping knife. During the first press stroke, the stepping knife cuts off, the side edge of the material, and punches are cut down. Then the material is fed, at step 6 a. In the second step, the knife cuts off the side edge of the material, the punches are cut out from d2sh1 4Y.

The GO knife is also an additional material consumption. Serving at the same time, for several steps, does not contribute to the economical use of the material,. the remainder of the material may be less than the feed step, and this increases the consumption of material and its transfer to waste.

The closest analogue of the claimed woodland model but the totality of features (prototype) is a device (stamp) for many, low-waste stamping, parts without inter-part jumpers made of sheet material, its biblio .: r graphic - data - a.s. USSR I04II93, M. 21 D 28D4. The stamping die contains a matrix with a securing strip that serves 15) as an extractor, a means for supplying the workpiece: for a step equal to two cutting steps, in the form of a side step knife, the length of the piece in the direction of material supply is twice the length of the part .i jRiy6aeMot . The device also contains a working tool, consisting of a punch installed in one row for cutting the part and means for separating the part along the contour in the form of a separate punch, and in the other row, means for separating the part along the contour part and segments adjacent to

her details in the form of a separate punch.

Punch for cutting a part and a punch for separation (parts along a part of the contour are installed sequentially in the direction of supply of material and placed one relative to the other. At a distance of the cutting step, cut an odd number of more than one, at a distance of three times the length of the part in the direction of supply of material.

A punch, for separating a part along a contour part and segments of an adjacent part, is installed in the material supply direction, behind a punch, for separating a part along a con part. round located in another center, at a distance from it, which allows you to cut and separate parts along the contour from the jumper formed by cutting and separating parts in an adjacent row. ,. .

Reasons that prevent obtaining the required technical result, i.e. The disadvantages of the well-known .. is the increased number of cut punches.

In addition, with such a multi-row cutting, it is difficult to obtain the same dimensions, parts due to uncontrolled spacing Shock / What to increase the gap between the contour parts, because cutting the full contour of the plate along transitions and from one reduction to another leads to line misalignment Cut. A stepping knife is provided in the design, which complicates the overall construction of the stamp and leads to additional material consumption. /

The task to which the claimed utility model is directed is to reduce the consumption of material when stamping parts by eliminating interdetails: side jumpers and simplifying the design by transferring the function of a stepping knife to punches, and the counter-spin of the matrix acts as an abutment for feeding the strip.

The essential signs of a characteristic and useful model include:.

- punches and dies located in the direction of material supply;

i- side knife

counter-spin (this is one of the walls of the matrix),

Features distinguishing a utility model:

- punches and dies are arranged stepwise along adjacent rows in the direction of the supply of material,

- the cutting edges of the punches and dies are parallel to each other

in the course of the material supply,

-1- the upper plane of Pr05va: door} of the kim is made above the plane of the side knife, which is fixed motionless.

The technical result when using the claimed utility model is expressed in simplifying the design of the stamp, increases the accuracy of the dimensions of the parts. ,

f consisting of a side knife 2, a backwash 3 g of the clip 4. Bepxitme Eyaskostzh 5, side knife 2 and the casing 4 are located on the same level. The protruding lever 3 has two functions, as the irrigating mechanism for the BCQX punches and as the main stop for feeding the nose 6 to the pitch, therefore, it is made higher with respect to the plane 5 of the side knife 2. For the 1 etching and the shaft 1 of the strip 6, the guide tubes 7 and 8 are rigidly mounted. Guide wall 9:. ,. , tash 7 on the same level with the upper plane of the wall; 10 anti-spin 3. In spring 8, spring-loaded clamps II are placed, which constantly feed the feed strip 6 to the wall 9 of the hyange 7 and to the wall 10 of the spin winder 3, while the wall 12 of the anti-spin 3 of the matrix is an abutment at the beginning of the feed of the strip 6,, the stamp works as follows way. ;: In the zone of the punch, a strip of b hearts is guided by guiding strips 7 and 8, rigidly fixed to a cage 4, along the walls 9 and 10 of the guiding bar 7 and the counterpress 3 under the first punch against the wall 12. The first punch is cut from the corner of the strip 6 by the first punch a plate (part) on two IEEE Cs on each side and falls through a composite matrix, consisting of a side HOJKa 2, a cotrotation plate 3 and a terminal; caged in a clip 4, in the opening of the lower I stamp, as part of the strip 6. The upper planes 5 of the side knife 2 and clips 4 are located on the same level. In this case, the anti-spin 3 performs two functions, as 1FOTIVOOTZHM 3 for all punches and as a stepping emphasis on the matrix walls 12 to feed the strip 6 per step, therefore, it is made higher with respect to the plane 5 of the side knife 2. After. die cutting of the first part, i.e. after trimming the edge of the strip to a certain length, in the direction of the hearth, chz1) and, it becomes possible to feed the strip b even further, already with the approach of strip 6 prd second punch. The strap 8, in which the spring-loaded clamps-C are placed, constantly sets the feed strip b to the wall 9 of the strap 7 and to the counterpressure wall 10 3. After cutting the second part of the first row and the first part of the second rad, the strip b is fed against the wall 12 of the presser 3 under the third - the punch and the cycle is repeated. In one stroke of the stamp at the end of the cycle, as many details are cut as

punches stepwise adjacent rows enclosed in a stamp. The number of blanks cut at the same time, the number of punches depends on the number of parts to fit in, the width of the workpieces of parts (

The inventive utility model allows to simplify the design of the stamp by eliminating the stepper movable knife, which in the modifications of the stamps is also an emphasis in the feed strip. By arranging the punches stepwise along adjacent rows, it was possible to abandon the v movable stepping knife, and at the same time stop in the feed of the strip, because the anti-spin wall of the matrix is made higher than the opposite one, where the side knife is fixedly fixed, performs its function (stop function). the knives are made by punches, with a stepwise expansion of them along adjacent ones, the cutting strip can be obtained without meadeal and side jumpers, that is, without waste.
