Attaching clamp’s drawing technology die design
Abstract：This design topic designs for The piercing die design of the dunnage backup plate, body now typical model The piercing die design of request, contents and direction.Pass the craft analysis, the craft project really settles, making sure the direction of The piercing die design, really settling to the blank product size, computing to the blanking pressure, compute the pressure center, choose the tonnage of the pressure machine and the pressure machine preliminary,and check the parameter of the machine.
    This design made use of to hurtle foundation knowledge of blanking craft and bending craft and The piercing die design. First, Analyzed the function request of the plank material, did preparation for the type that chooses to the die, is also convex, in the meantime, the material of punch and cavitydie had a basis.Analyze to hurtle a characteristic of cut the piece behind, make sure the molding tool design parameter, choose other spare partses and unload to anticipate device.Is also convex, the calculation of the cave mold size had a basis.Still there is spare parts to process a craft.
Keywords:   The piercing die   punch   cavitydie  punch-die  bending die
