Forming device of silver soldering sheet for soldering of blade and hard alloy sheet

Abstract

The invention discloses a forming device of a silver soldering sheet for soldering of a blade and a hard alloy sheet. The device comprises a base; the base is provided with a lower forming plate capable of moving horizontally and a limiting block capable of moving vertically; the limiting block, the lower forming plate and the base cooperate to form forming gaps; the upper end of the lower forming plate is provided with a first inclined forming surface, one end of the first inclined forming surface is provided with a first convex forming arc, and the other end of the first inclined forming surface is provided with a first concave forming arc; an upper forming plate is rotationally arranged above the base; the side end of the upper forming plate is provided with a second inclined forming surface matched with the first inclined forming surface; one end of the second inclined forming surface is provide with a second concave forming arc matched with the first convex forming arc; and the other end of the second inclined forming surface is provide with a second convex forming arc matched with the first concave forming arc. The forming device is simple in structure and easy to operate, forming of the silver soldering sheet is conducted through the forming device, the production efficiency is greatly improved, and the production cost is effectively reduced.

Description

technical field [0001] The invention relates to a tooling fixture, in particular to a forming device for a silver soldering sheet for blade brazing hard alloy sheets. Background technique [0002] When the blade is brazing the alloy sheet, the silver solder sheet with a common sheet structure is used, such as figure 1 As shown in Fig. 1, the silver solder sheet of this structure is used for brazing. During the induction heating process, the silver solder sheet melts, and the silver solder sheet guides the filling of the weld by heat transfer; during the filling process of the silver solder sheet, the alloy sheet will move. , the capillary action is weakened, resulting in insufficient bonding of the solder between the blade and the alloy sheet after brazing, and more pore defects. [0003] In view of the above problems, some manufacturers use silver soldering pieces whose shape fits the blades for brazing, such as figure 2 As shown, the silver solder sheet of this structur...
