Description

The invention relates to tooling for sheet punching and can be used in mechanical engineering. An izvenno device for multi-day low-waste punching of details of jumper details of sheet material, containing a working tool consisting of installed in one row sequentially in the feed direction of the material of the punch for cutting the part and means for separating the part of the contour, placed one relative to the other step of cutting, multiplied by an odd number more than one, in another row - means for separating the part on the part of the contour and segments of the adjacent q part, as well as the means The possibility of supplying the workpiece to a step equal to two steps of cutting .l3. A disadvantage of the known devices is that it is resistant because of the means for separating a part of the contour part of asymmetrically arranged cutting edges on one row, which leads to an increase in zazbra between the die and punch, and this in turn affects. quality of the parts. Part of the parts in the manufacture of such a device are connected by a thin jumper, which requires additional processing I. The purpose of the invention is to increase the durability of the device and the quality of the parts. To achieve this goal, in an arrangement for multi-one low-waste stamping of parts without interdetal jumpers of sheet material, containing a working tool consisting of installed ones in one row successively in the feed direction of the material of the punch for cutting the part and the means for separating parts of the contour are placed one relative to another. At the distance of the cutting step multiplied by an odd number more than one, in another row there are means for separating the part along the contour and segments of the part adjacent to it, also means providing the opportunity to feed the workpiece to a step equal to two steps of cutting, means for separating the part along the contour and segments of the adjacent part and means for isolating the part along the part of the contour are made as separate punches; the direction of feed of the material beyond the second distance from it, which allows one to cut, and separate the parts along the contour from the jumpers formed during cutting and separation of parts in the adjacent row. In addition, the working tool additionally contains punches for punching holes, installed in each row and placed at the position of segments of parts and in the direction of material feed before the punches for cutting and separating parts along the contour part at: distance from them, multiple to double cutting step. FIG. 1 shows a device for stamping rectangular partsJ in FIG. 2 is the same for stamping hexagonal parts. The DL multi-unit low-waste device for stamping parts without inter details hinges from sheet material contains a working tool consisting of punch 1 installed in one row for cutting the part and means for separating the part along the contour as a separate punch 2 and in another DU - means for separating the part along the contour part and segments of the adjacent part as a separate punch 3. The punch 1 for cutting the part and the punch 2 for separating along the part of the contour are installed successively in the feed direction of the material a and arranged relative to one another at a distance of the cutting step, multiplied by an odd number greater than one, e.g., at a distance, tripled details length in the feed direction mA; the material. . A punch 3 for separating the part along the contour part and segments of the adjacent part is installed in the material feed direction behind the punch AND for separating the part along the contour part located in the other row, at a distance from it allowing it to be cut and separated. a contour from a lintel formed when cutting and separating parts in the adjacent row (for example, when stamping right-angle parts, at a distance of two cuts, and 1 hexagonal ones — one and a half cuts). The device has a means of enabling the sub-workpieces to be cut into a step equal to two steps of cutting, for example, in the form of a side step knife 4, the length of which is in the direction of the material feed; equal to the DOUBLE length of the cut part. When punching hexagonal parts, an additional side knife 5 is installed in the device. The working tool additionally contains punches b for punching holes in the parts, installed in the hygiene row and placed in the position of sections of the lethal and in the material feed direction by punches for cutting and separating the parts by part contours at a distance from them, which is a double double step of cutting.

The device works as follows.

When feeding the belt 7 to the first and subsequent strokes of the press ram: (not shown), the lateral stepping knife forms an edge of the belt with a length equal to the feed pitch.

After the tape is fed, a step at the second and third moves is carried out by cutting the details with punch 1.

On the fourth turn, it is cut down; the detail by punch 1, and in the same p

the part on the contour part is separated by the punch 2 ..

During the first run, the part is cut down in one row by the punch 1 and the part is separated from the part of the contour by the punch 2, and in the other, the punch 3 separates the part from the part of the contour and the part adjacent to it is cut off.

Then, for each stroke of the press ram, ten parts are connected during five-sided stamping.

In the manufacture of parts with holes, in addition, in each row of punches, J must be cut off in the tape and in the parts to be cut.
