SU1655754A1 - Method and die set for making three-dimensional structures from metal strips - Google Patents

Abstract

FIELD: mechanical assembly. The purpose of the invention is to expand technological capabilities and reduce labor intensity. The tapes or sheets of metal are cut into strips (P) 10. In P 10, grooves with a width smaller than P 10 are punched. Then P 10 are joined in inserts by their mutual pressing. In order to avoid deformations, the pressing is performed on a stamp, on which, prior to the impact of the punch, the fingers above and the bottom of the fingers are inserted into the grooves 9, which are pressed in, in which the pressing is performed. The carriage serves to form the longitudinal strips into the desired contour and to advance this contour as the transverse strips are added. 2 sp.f-ly, 4 Il.

The invention relates to mechanical assembly work and can be used in the manufacture of spatial structures from metal strips.

The purpose of the inventions is the expansion of technological capabilities by ensuring the fabrication of metal gratings with uniform electrical conductivity, and TSKV reducing the labor intensity of manufacturing.

Figure 1 shows a separate strip of the lattice; Fig. 2 shows a lattice in two projections; on fig.Z - stamp, general view; figure 4 is the same, top view.

A punch for carrying out the method comprises a punch 1, the guide pins 2 are located in front of the punch and to the left of it. The puller 3 is rigidly fixed on top of the pins 4 of the matrix 5 on the matrix. 7, removable transverse strips 8 are installed. In the grooves 9, between the guide fingers 4, the bars 10 of the grid are installed. The guide pins 2 are separated by similar grooves.

The method includes sequentially performed operations: sheets or strips of sheet metal are cut into strips 10 on any suitable scissors in size and punched into them grooves 11 in the form of tie-ins of equal distances from each other. The grooves can be milled in bags, preferably, however, punch on the stamps. This is followed by pressing the bands on the stamp.

The strips with the removed transverse strips 8 are mounted on the matrix 5, passing them through the grooves 9 between the guide fingers 4 under the puller 3. After collecting the required number of strips, the transverse strips 8 are put in place, thus forming the longitudinal base of the lattice. The strips are put across the transverse strip, shifting it down until the slots of the transverse strip go along the slots of the longitudinal, i.e. half. Then include a press, preferably hydraulic. When the punch 1 moves downward, the guide fingers 2 and 4 initially form a closed space for the compressed strips in which the deviation of the strip from the direction of crimping is impossible, after which the punch 1 lowers the transverse stripe and the mutual crimping of the strips occurs. During the course of the punch upward puller 3 keeps the grill from a possible rise after

punch. The carriage 7 is moved along the grooves 6, a new transverse strip is inserted and pressed in, and after the last transverse strip is pressed in, it is removed
