Abstract

The invention relates to the processing of metals by pressure and can be used for the manufacture of thin-walled tubes from sheet steel. The purpose of the invention is to make it possible to manufacture thin-walled metal shells from flat sheet blanks. With cylinders 7, bending matrix 8 is fed upward and bends the lower part of the flat blank. Then the clamping plates 16 under the influence of the pneumatic cylinders 14 through the pivot-lever linkages 17 bend and press the upper part of the workpiece to the cantilever mandrel 6. After that, the drive carriage 4 with the tool passes the entire length of the workpiece, forming a flange connection. The proposed device design allows operation in automatic mode. 15 il.

Claims (1)

Claim A device for connecting the edges of sheet blanks with a seam weld, comprising a base installed in the guides of the drive carriage with a folding and folding tool placed on the carriage with the possibility of interaction with the support beam, as well as clamping rotary strips associated with articulated link links and a pneumatic drive, characterized in that, in order to increase productivity in the manufacture of thin-walled metal shells, it is equipped with two racks. fixed on the base, placed between them perpendicular to the base, pneumatic cylinders, a mechanism for synchronizing the movement of their rods and a bending matrix. associated with the rods of the pneumatic cylinders, while the guides are mounted on the upper ends of the racks, the support beam is made with a working surface for bending and is cantilevered in one of the racks under the guides, the mechanism for synchronizing the movement of the rods is made in the form of a shaft mounted in racks on bearings parallel to the guides. · fixed on 10 to the gear shaft and fixed on the lateral sides of the bending matrix, facing the uprights with the possibility of engagement with the gears of the gear racks, the pneumatic drive of the clamping bars is placed above the carriage guides, and the bars are located on both sides of the guides with the possibility of rotation and interaction with the upper part of the support beam. view in tikiz.2 7 Fie. 9 Φυζ. 10 d ------- ιή _ν FIG. thirteen Vt --- Nt ----- V Fie 19 Fig. 15
