Description

The invention relates to the field of metal forming by cold stamping and can be used for simultaneous cuts at different heights of the output ends of the contacts in multi-contact, including double-row blocks, connectors and boards, etc. in the electronic industry, instrument making.

The invention is known "Device for cutting the conclusions of the radioelements" (AS No. 1439755 from 07/02/1986), containing a mechanism for supplying radioelements connected to the drive knives, in the cutting plane of which are made of pointed protrusions, and on the other - their corresponding depressions, characterized the fact that, in order to improve the quality of the product, one of the knives is made with centering teeth for the conclusions of microcircuits located on its cutting edge.

The purpose of the invention is improving quality by simultaneously trimming and sharpening the conclusions of the radioelements.

The disadvantage of this device is that the proposed mechanism allows you to produce a segment of only single-row conclusions and only at one height.

The closest analogue in technical essence is the invention "Device for cutting the conclusions of the radio elements" (AS No. 302858 of 08/15/1969), containing knives and a drive mechanism, characterized in that, in order to selectively cut the conclusions of the radio elements and improve the performance of the device, it is equipped with spring-loaded clamps with protrusions and grooves, with eccentrics placed in the grooves, and the protrusions interact with the grooves made in the knives and levers, each shoulder of which ends with a key, and on the other support etsya one of the knives.

The device allows to mechanize harvesting operations, increases labor productivity, improves the quality of cutting.

The disadvantage of this device is the segment of one row of conclusions in manual mode.

The technical result achieved by the invention consists in the possibility of cutting the ends of the terminals of the plug connectors, pads, boards, simultaneously or in one row (for single-row connectors) or two rows (for double-row connectors) at different heights of the segments in each row. In this case, the segment occurs mechanically with a strictly defined size, the height segments without deformation of the cut-off and not-cut contacts with respect to the housing.

The purpose of the invention is the expansion of operational capabilities, increasing labor productivity, improving quality during the operation, the contact segments of radio elements.

The invention is illustrated by figures 1, 2, 3.

In FIG. 1 is a front view of a stamp.

In FIG. 2 shows a stamp view from above.

In FIG. 3 shows the principle of operation of the stamp.

The stamp for simultaneous contact cuts (Fig. 1) consists of a movable top plate (1) to which a spring-loaded clamp (2) and two wedges (3) are attached, right and left. A matrix (5) is attached to the bottom plate (4), having stepped protrusions forming cutting edges at different heights A1 and A2. In the bottom plate (4) there are two movable crawlers with punches (6), forming the second cutting edges at heights A1 and A2. The top plate and the bottom plate are interconnected by columns (7) (Fig. 2).

The stamp is as follows.

When the top plate is raised (1), the creepers with punches (6) are moved apart by wedges (3) to the right and left. After installing the cut-off part (8) in the stencil, the top plate (1) first presses down the workpiece (8) with a clamp (2) and then moves the wedges (3) with the further wedges (3) to the part, where it happens a segment of contacts on the dimensions A1 and A2 by the cutting edges of the matrix and punch. By moving the plate top (1) upward, the creepers with punches (6) by wedges (3) remove the punches from the die, and the clamp (2) releases the part (8). Next, the cycle repeats.

The advantage of the present invention is that due to the use of creepers with punches forming the second cutting edges at different heights, the cut occurs simultaneously or in the same row or two rows and at different heights, the cuts in each row with a fixed size cut in height. In the proposed form, the segments on the stamp do not deform the cut-off and not-cut conclusions with respect to the housing. The cut is smooth, without deformation along the line and plane of the cut. Cutting the profile of the conclusions may have a different cross-section (round, square, rectangular, etc.) (Fig. 3).

Claims (1)

A stamp for simultaneous contact cuts, consisting of a top plate to which a spring-loaded clip and two wedges are attached - right and left, a bottom plate to which a matrix is attached, having stepped protrusions forming cutting edges at different heights A1 and A2, with the upper plate and the lower plate is interconnected by columns, characterized in that the stamp is equipped with movable creepers, movable wedges and bearing punches that form the second cutting edges at different heights A1 and A2.
