Abstract
The present invention discloses a kind of edge of a knife blanking die, including workbench and knife edge due, the knife edge due inner hollow, bottom is the cutting knife matched with stamping shape, blanking bar is fixed with the internal cavities of the knife edge due, the bottom of the blanking bar is provided with buffer unit, and the top of the buffer unit is fixed on the inwall of the knife edge due, and bottom is connected with blanking pushing block.Material is gone out the shape of needs using the cutting knife of knife edge due bottom for the present invention, and simple structure directly separates material, the stamping for needing is obtained, meanwhile, blanking pushing block is set in knife edge due, when rising after the completion of knife edge due stamping, blanking pushing block promotes material to separate, easy to use.
Description
Technical field
The present invention relates to a kind of blanking die, specifically a kind of edge of a knife blanking die.
Background technology
In production and processing field, the general parts that metallic article is processed using mould.There are the parts of polymorphic structure for some, blanking die is the punch die of punch part or blank on sheet material, but the structure of existing blanking die is mostly complicated, and stability is poor in blanking process；In addition, in addition to cavity plate, punch-pin, concave-convex mold except unique structure to be designed etc. are to meet actual production processing needs, also needing to drift has enough impulse forces, could complete the processing of key position, and this service life undoubtedly to mould in itself exerts a certain influence.
The content of the invention
Goal of the invention：Present invention aim in view of the shortcomings of the prior art, there is provided a kind of simple structure, the edge of a knife blanking die for directly separating material.
Technical scheme：Edge of a knife blanking die of the present invention, including workbench and knife edge due, the knife edge due inner hollow, bottom is the cutting knife matched with stamping shape, blanking bar is fixed with the internal cavities of the knife edge due, the bottom of the blanking bar is provided with buffer unit, and the top of the buffer unit is fixed on the inwall of the knife edge due, and bottom is connected with blanking pushing block.
Further preferably technical scheme is to be additionally provided with backing plate between the cutting knife and the workbench to the present invention.
Preferably, the backing plate is plastic plate or plank.
Preferably, the buffer unit is buffer spring.
Preferably, gap is left between the blanking pushing block and the inwall of the knife edge due.
Preferably, the blade angle of the cutting knife is 10 ~ 20 °.
Beneficial effect：（1）Material is gone out the shape of needs using the cutting knife of knife edge due bottom for the present invention, and simple structure directly separates material, the stamping for needing is obtained, meanwhile, blanking pushing block is set in knife edge due, when rising after the completion of knife edge due stamping, blanking pushing block promotes material to separate, easy to use；
（2）The present invention sets backing plate between cutting knife and workbench, it is to avoid damage otch, lifts the service life of blanking die；
（3）In the present invention, gap is left between blanking pushing block and the inwall of knife edge due, stamping can be prevented to be stuck in the inner chamber of knife edge due, damage knife edge due.
Brief description of the drawings
Fig. 1 is the structural representation of edge of a knife blanking die of the present invention.
Specific embodiment
Technical solution of the present invention is described in detail below by accompanying drawing, but protection scope of the present invention is not limited to the embodiment.
Embodiment 1 ：A kind of edge of a knife blanking die, as shown in figure 1, including workbench 1 and knife edge due 2, plastic base plate 3 is additionally provided between knife edge due 2 and workbench 1.
The inner hollow of knife edge due 2, bottom cutting knife 21 is installed according to the stamping shape that need to be processed, the blade angle of cutting knife 21 is 20 °, blanking bar 22 is fixed with the internal cavities of knife edge due 2, the bottom of blanking bar 22 is provided with buffer spring 23, the top of buffer spring 23 is fixed on the inwall of knife edge due 2, and bottom is connected with blanking pushing block 24, and gap is left between the inwall of blanking pushing block 24 and knife edge due 2.
Although as described above, having been represented with reference to specific preferred embodiment and having described the present invention, it shall not be construed as to the limitation of itself of the invention.Under the premise of the spirit and scope of the present invention for not departing from appended claims definition, can various changes can be made in the form and details to it.
