Embodiment

As shown in Fig. 1 to 5, the utility model provides a kind of wheel and wraps simple perforating die, and it includes：Upper mould fixed plate 1 and its On punch-head assembly 2, lower mold fixed plate 3 and punch assemblies 4 thereon, wheel contract for fixed output quotas product stamping parts 5 with a processing plane 6, institute State and be disposed with processing plane 6：Macropore 7 positioned at center, and four apertures 8 positioned at the periphery of macropore 7, wherein：It is described Punch-head assembly 2 includes the big drift 9 and small drift 10 corresponding with the macropore 7 and the aperture 8, and the punch-head assembly 2 Outer end be disposed with holding pad 11；The punch assemblies 4 include：Punch-pin location type face 12, the punch-pin location type face 12 and institute State processing plane 6 between plane-plane contact position, and be vertically arranged on the punch-pin location type face 12 respectively with the big drift 9 The punch-pin macropore 13 and punch-pin aperture 14 being engaged with the small drift 10；And also it is installed with the lower mold fixed plate 3 There is the positioning to match with the outer surface for taking turns product stamping parts 5 of contracting for fixed output quotas to support for support base 15, the top of the support base 15 Type face 16.

As a further improvement, wrapped between the positioning support type face 16 and the punch-pin location type face 12 along the wheel The axial direction of product stamping parts 5 has interval.

As a further improvement, the 16 V-shaped supporting surface of positioning support type face.

As a further improvement, the punch-head assembly 2 is fixedly connected through fixed plate 17 with the upper mould fixed plate 1.

As a further improvement, the punch-head assembly 2 also includes between the big drift 9 and the small drift 10 The multiple springs 18 being longitudinally arranged, the end of multiple springs 18 leans with the holding pad 11 to be contacted.

Mainly in punch process, upper/lower die closure, holding pad is first pressed onto on punch-pin punching location type face holding pad, and two Individual type face matching, mould continue to push, and after pressing spring in place, 5 drifts of upper mould complete punching, spring force after mould backhaul The lower holding pad of effect returns to initial position.

As a further improvement, the support base 15 is L-shaped.

The utility model is realizes that the change switching punching that sets of stamping parts provides a kind of simple die, than formal casting die both Improve efficiency and save expense again.Ensure to realize the switching in hole during production, without using changing punching when without the hole Casement, it is necessary to when use.The simple perforating die is simple in construction, easy to use, greatly reduces cost of investment and using effect Rate.The mould is that general steel plate welding is process, and efficiency high, cost is low, meets punching demand.

In the utility model, upper and lower mould fixed plate mainly realizes the peace of fixation and each workpiece of the mould on lathe Dress；Holding pad 11 and punch assemblies 4 realize positioning of the stamping parts on simple perforating die and final punching.Support base 15 is main Realize the auxiliary positioning of stamping parts, it is larger mainly due to stamping parts, on small lathe on place during need increase by one Individual Auxiliary support, ensure the positioning that stamping parts can be stablized under gravity.The servicing unit will also ensure in actual use Part and lathe are not interfered；Wheel contracts for fixed output quotas product stamping parts 5 to need the part of punching to place form, because of five holes in one plane, is Simplify mould structure, it is necessary to the angle for ensureing punching is vertical, could so realize the most simplified of mould.

First according to the placement direction of punching angle Selection stamping parts, ensure that 5 hole punch sides are placed for plane.Punch-pin is determined Bit-type face 12 and positioning support type face 16 are processed according to the placement direction of stamping parts, are finally employed the positioning of type face, are ensured The validity of positioning.Support base, which realizes part and lathe in placement process of the stamping parts on lathe, does not interfere, and ensures simultaneously The stabilization of part, solve the problems, such as positioning and operational stability.

The utility model is in operation, the first step：Mould upper and lower mould is fixed on lathe, upper and lower mould is under lathe effect Punching；Second step：Stamping parts is manually placed on mould, type face symbol type, fixed stamping parts according to type face position, position Rear mold presses under lathe effect in place, finally realizes the punching of stamping parts.

The utility model solves the orientation problem of stamping parts, ensures the accuracy of punching module positioning；The angle of punching Problem, ensure the optimization structure of perforating die；And operational problem of the part in the production of actual lathe.This programme rushes to realize The change switching punching that sets of casting die provides a kind of simple die, had not only improved efficiency than formal casting die but also had saved expense.

It should be appreciated that the utility model scope of the claimed is not limited to non-limiting embodiments, it should be understood that non-limiting reality Scheme is applied to illustrate as just example.The desired substantive protection domain of the application is more embodied in independent claims The scope of offer, and its dependent claims.
