METHOD FOR STAMPING WRENCHES Russian patent published in 2022 - IPC B21K5/16 

FIELD: metal processing.

SUBSTANCE: invention relates to the processing of metals by pressure and can be used for hot plastic processing of elongated steel forgings on a hammer of horizontal layout. From the strip heated in the pass-through inductor, a continuous flat blank is obtained by an element-by-element segment of the opposite sections to be removed with the formation of sections for the handle of the wrench. At the same time, the design of the grooves in the locations of the wrench jaws is carried out. Adjacent blanks are connected by heads and an S-shaped section is obtained at the junction. Then, at the residual temperature, the blank is oriented by turning 90° and fed to the position of the impact masses of the hammer. In one impact, a section of a flat blank is deformed, which falls on one forging of a wrench. At the same time, the stamped forging is separated in the cutoff.

EFFECT: as a result, a reduction in the number of stamping operations and transportation of the blank at the processing stages and positioning at the point of collision of the moving masses of the hammer is ensured.
