Description

Blanking apparatus

Technical field

The utility model relates to the punching press cutting means, especially a kind of punching press cutting means that is applicable to objects such as multi-layered textile thing, leather.

Background technology

Adopt the manual layers of cloth firmly stitched together for soles of cloth shoes cloth shoes of receiving the end, shoe-pad durable, comfortable and easy to wear and be subjected to consumer's welcome deeply, waste time and energy, need when patching up line hole on sole or shoe-pad with boring endlessly but make with it.Therefore at present therefore adopt by the blanking of machine stamping-out, and existing blanking apparatus can only blanking, and can not stamping out on sole or shoe-pad simultaneously for the pinprick of patching up line can only use the sewing machine rolling line instead more, and this has reduced the durability of cloth shoes, shoe-pad inevitably.In addition, the cloth shoes that institute's stamping-out goes out, the last bottom surface of shoe-pad are the plane, the cambered surface that the object that is stamped is formed adapt with pin shape or have the not sole of equal thickness as slipsole etc. on its longitudinal cross-section.

The utility model content

Technical problem to be solved in the utility model provides a kind of blanking apparatus that can also stamp out pinprick (hole) when stamping-out goes out object thereon.

The technical scheme that its technical problem that solves the utility model adopts is: blanking apparatus of the present utility model, but the staking punch and the cover half that comprise a pair of move toward one another, a staking punch and cover half end in opposite directions is provided with dynamic model and annular blade, the outline of the outline of annular blade, dynamic model and cover half die head and institute's punching press object is suitable, it is characterized in that: offer the through hole that passes for punch rod on the die head of described cover half, punch rod is fixed on the pedestal, and cover half is connected with pedestal; Offer on the dynamic model and the corresponding hole of through hole.

The head of described punch rod is tip-like, or has and the corresponding to cutting edge of hole profile that is stamped.

As improvement of the technical scheme, fractureed in punching course for avoiding punch rod, cover half is connected with pedestal by at least two guide spiro rods, and being provided with between pedestal and the cover half can be along the elastic component of pressing direction compression.

The beneficial effects of the utility model are, along with punch assembly descending, when determining object, the cover half upper punch determines pinprick or through hole in the object upper punch, improved the efficient of processing object greatly, and reduced workman's the amount of labour, be convenient to make the layers of cloth firmly stitched together for soles of cloth shoes cloth shoes produced, shoe-pad etc. more durable by the manual line of patching up.

Further improvement as above technical scheme, for finalizing the design to the object mold pressing of institute's stamping-out, make it on the longitudinal cross-section, have thickness or the cambered surface of lower surface formation thereon that does not wait, thereby make the layers of cloth firmly stitched together for soles of cloth shoes cloth shoes produced, shoe-pad etc. more attractive in appearance and comfortable, described dynamic model, die head face in opposite directions for respectively with the corresponding to forming surface of the upper and lower surface configuration of institute's punch forming object.

The punching press that blanking apparatus of the present utility model especially is suitable for objects such as multi-layered textile thing, leather cuts with mold pressing finalizes the design.

Description of drawings

This specification comprises following three width of cloth accompanying drawings:

Fig. 1 is the structural representation of staking punch in the utility model blanking apparatus;

Fig. 2 is the structural representation of cover half in the utility model blanking apparatus;

Fig. 3 is the vertical view of cover half in the utility model blanking apparatus.

Parts, position and numbering among the figure: staking punch 10, dynamic model 11, annular blade 12, forming surface 13, hole 14, scotch 15, cover half 20, cover half head 21, through hole 22, forming surface 23, guide spiro rod 24, elastic component 25, pedestal 30, punch rod 31, pole socket 32.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

As Fig. 1, Fig. 2 and shown in Figure 3, blanking apparatus of the present utility model, but the staking punch 10 and the cover half 20 that comprise a pair of move toward one another, staking punch 10 is provided with dynamic model 11, annular blade 12 with cover half 20 end in opposite directions, and the outline of annular blade 12, dynamic model 11 and cover half 20 die heads 21 and the outline of institute's punching press object are suitable.Offer the through hole 22 that passes for punch rod 31 on the die head 21 of cover half 20, punch rod 31 is fixed on the pedestal 30, and cover half 20 is connected with pedestal 30.Offer on the dynamic model 11 and through hole 22 corresponding holes 14.The head of punch rod 31 is tip-like or has and the corresponding to cutting edge of hole profile that is stamped, and can stamp out pinprick and/or through hole on object.

As shown in Figure 2, fractureed in punching course for avoiding punch rod, cover half 20 is connected with pedestal 30 by at least two guide spiro rods 24, and being provided with between pedestal 30 and the cover half 20 can be along the elastic component 25 of pressing direction compression.Described elastic component 25 can be sleeved on the guide spiro rod 24, also can be arranged between the upper surface and cover half 20 lower surfaces of pedestal 30, locatees by structures such as pits.Elastic component 25 can adopt the flexible member of compression spring, butterfly spring or other kinds.

As shown in Figure 2, for ease of the installation and the replacing of punch rod 31, punch rod 31 can be fixedly set on the pole socket 32 that removably connects with pedestal 30.

For can be to institute stamping-out object mold pressing typing, the thickness or the cambered surface of lower surface formation thereon that object are had does not wait on the longitudinal cross-section, dynamic model 11, die head 21 face in opposite directions be respectively with the corresponding to forming surface 13,23 of the upper and lower surface configuration of stamping-out object.See figures.1.and.2, when staking punch 10 during, dynamic model 11 and the tight object of die head 21 mold pressings with cover half 20 move toward one another because annular blade 12 and dynamic model 11 can relatively move, therefore can stamping-out down and the corresponding to object of outline of die head 21.Dynamic model 11 can adopt two kinds of set-up modes on staking punch 10, promptly can be fixed on the staking punch 10, is maintained fixed with annular blade 12; Dynamic model 11 also can relatively move along staking punch 10 directions of motion and annular blade 12 generations, and this kind mode should be provided with scotch 15 on staking punch 10.As shown in Figure 1, when dynamic model 11 with after scotch 15 contacts, dynamic model 11 stops to relatively move with annular blade 12, staking punch 10 moves downward, cover half 20 will overcome the elastic force of elastic component 25, drive that it is descending, make the through hole 22 of punch rod 31 from cover half 20 and go out, on object, stamp out pinprick and/or through hole.After a punching stroke finished, along with the rising of staking punch 10, cover half 20 resetted under elastic component 25 effects, and punch rod 31 is deviate from from object.Relative motion between staking punch 10 and the cover half 20 can realize by multiple mechanical motion mode.

It is pointed out that top described principles more of the present utility model that just explain through diagrams, because the those of ordinary skill in constructed field is easy to carry out on this basis some modifications and change.Therefore, this specification be not be the utility model to be confined to shown in and in described concrete structure and the scope of application, so every the corresponding modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
