Preferably, described molding concave die beryllium copper part adopts beryllium copper material, and described molding concave die cold work die steel part adopts cold work die steel.Be embedded into by beryllium copper in shaping workpiece, molding concave die beryllium copper part bending R bight is divided into beryllium copper material, and bending straight portion is cold work die steel material.
Preferably, described molding concave die beryllium copper part is provided with projection, and described molding concave die beryllium copper part is embedded on described molding concave die by projection.
Preferably, described molding concave die beryllium copper part is provided with automatic oiling hole, without the need to manual oiling, can improve stamping production efficiency.
As mentioned above, a kind of Novel punching mould of the present utility model, has following beneficial effect:
1. by shaping workpiece bending R angle beryllium copper material, the elastic deformation utilizing beryllium copper stressed improves the mobility of material, solves and draws the thick problem such as thinning of trace, cracking, material; Shaping workpiece straight flange draws stretches part employing cold work die steel, utilize the feature of the comparatively strong not easily stress deformation of its hardness, ensure the dimensional stability that product straight flange stretches, thus utilize the physical characteristic of unlike material, beryllium copper and cold work die steel combination are utilized, solves the problem that product draws trace, cracking, drawing and forming poor dimensional stability.
2. shaping workpiece adopts embedded, convenient disassembly, is convenient to safeguard.
3. shaping workpiece beryllium copper part has automatic oiling hole, without the need to manual oiling, improves stamping production efficiency.

1-forming convax mould, 2-molding concave die, 21-molding concave die beryllium copper part, 22-molding concave die cold work die steel part, 3-processed product, 4-shaped article, 6-patrix, 7-counterdie, 8-to post.
Detailed description of the invention
By particular specific embodiment, embodiment of the present utility model is described below, person skilled in the art scholar the content disclosed by this description can understand other advantages of the present utility model and effect easily.
Refer to Fig. 1.Notice, structure, ratio, size etc. that this description institute accompanying drawings illustrates, content all only in order to coordinate description to disclose, understand for person skilled in the art scholar and read, and be not used to limit the enforceable qualifications of the utility model, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under effect that the utility model can produce and the object that can reach, still all should drop on technology contents that the utility model discloses and obtain in the scope that can contain.Simultaneously, quote in this description as " on ", D score, "left", "right", " centre " and " one " etc. term, also only for ease of understanding of describing, and be not used to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, under changing technology contents without essence, when being also considered as the enforceable category of the utility model.
As shown in Figure 1, a kind of Novel punching mould that the utility model provides, comprise patrix 6, counterdie 7, forming convax mould 1 is provided with below described patrix 6, molding concave die 2 is provided with above described counterdie 7, described molding concave die 2 matches with described forming convax mould 1, and the inside of described molding concave die 2 is provided with to post 8, and described molding concave die 2 comprises molding concave die beryllium copper part 21 and molding concave die cold work die steel part 22.
As a kind of specific embodiment, molding concave die beryllium copper part 21 is provided with smooth arc-shaped surface, and described molding concave die cold work die steel part 22 is provided with vertical shiny surface.
As a kind of specific embodiment, molding concave die beryllium copper part 21 adopts beryllium copper material, and described molding concave die cold work die steel part 22 adopts cold work die steel.Be embedded into by beryllium copper in shaping workpiece, molding concave die beryllium copper part bending R bight is divided into beryllium copper material, and bending straight portion is cold work die steel material.Molding concave die cold work die steel part adopts DC53 mould steel.
As a kind of specific embodiment, molding concave die beryllium copper part 21 is provided with projection, and described molding concave die beryllium copper part 21 is embedded on described molding concave die 2 by projection.
As a kind of specific embodiment, molding concave die beryllium copper part 21 is provided with automatic oiling hole, without the need to manual oiling, can improve stamping production efficiency.
When carrying out work, be placed on by processed product 3 between forming convax mould 1 and molding concave die 2, patrix 6 moves downward under the promotion of cylinder, and processed product 3 is pressed onto in the die of molding concave die 2 by forming convax mould 1, until contact with the post 8 that supports in molding concave die 2, complete punch forming step.The straight flange of processed product 3 stretches and straightens by the molding concave die cold work die steel part 22 of molding concave die 2, ensure the linear side dimension stability of shaped article 4, tensile foldable is carried out in the bending R angle of processed product 3 by 21 points, the forming convax mould beryllium copper portion of molding concave die 2, avoids the bending R angle of shaped article 4 to occur drawing the thick problem such as thinning of trace, cracking, material.
Beryllium copper is more weak relative to cold work die steel hardness, but elasticity is better.During product drawing and forming, under the effect of extruding force, there is plastic deformation in material because cold work die steel workpiece hardness is comparatively large, material be squeezed power generation plastic deformation time mobility poor, easily draw the thick phenomenon such as thinning of trace, cracking, material.But because beryllium copper hardness is more weak, after stressed, can elastic deformation be there is, so during product stretching straight flange, there will be bending size wild effect.In order to address this problem, we are by shaping workpiece bending R angle beryllium copper material, and the elastic deformation utilizing beryllium copper stressed improves the mobility of material, solve and draw the thick problem such as thinning of trace, cracking, material; Shaping workpiece straight flange draws stretches part employing cold work die steel, as DC53, utilizes the feature of the comparatively strong not easily stress deformation of its hardness, ensures the dimensional stability that product straight flange stretches.
As mentioned above, a kind of Novel punching mould that the utility model provides, by utilizing the physical characteristic of unlike material, utilizing beryllium copper and cold work die steel combination, solving the problem that product draws trace, cracking, drawing and forming poor dimensional stability; Shaping workpiece adopts embedded, convenient disassembly, is convenient to safeguard; Shaping workpiece beryllium copper part has automatic oiling hole, without the need to manual oiling, improves stamping production efficiency.So the utility model effectively overcomes various shortcoming of the prior art and tool high industrial utilization.
Above-described embodiment is illustrative principle of the present utility model and effect thereof only, but not for limiting the utility model.Any person skilled in the art scholar all without prejudice under spirit of the present utility model and category, can modify above-described embodiment or changes.Therefore, such as have in art and usually know that the knowledgeable modifies or changes not departing from all equivalences completed under the spirit and technological thought that the utility model discloses, must be contained by claim of the present utility model.
