Description
Technical field
It the utility model is related to a kind of diel, and in particular to a kind of secondary stamping and blanking mould on contact pin class product head
Tool.
Background technology
Terminal as shown in Figure 1 is contact pin class product applied to all kinds of automobile instruments, car electrics connector, product material
Expect for each metalloid material, product batch is especially big, and the process for producing such product is to use all kinds of " the grading punchings of multistation
Compression mould " carries out multiple works such as punching production, metal plate material strips are punched on one pair of mould, flanging, bending, cut-out
Sequence completes production, a width dimensions typically only thick size of material for its pin head（0.4~0.8mm）, it is herein connection
The contact site of circuit, the outward appearance and size at the position require higher, it is desirable to accurate size, punching section impulse- free robustness, contact pin table
Face is smooth, to reach the requirement of fine substantially, but traditional multi-station progressive stamping mould is when producing such this position of product
Drawbacks described above is easily produced, causes that product percent defective is high, low production efficiency, mold repair cost is very high.
The conventional ones mould process figure of this pin head and expansion Layout as shown in Figures 2 and 3, due to pin head
It is small-sized, only one material 0.4 ~ 0.8mm of thickness, restricted by punching punch and matrix tool intensity, its punching process arrangement is divided into
2 processes, first step blank operation punching head left side waste material 71, second step blank operation punching head the right waste material 72, stay
Under material be exactly pin head live part, in two step stamping procedures due to being all unilateral punching press, head material during punching press
By one, a unidirectional side extruding force to the left, this extruding force promotion material are moved, are punched material to side to the right
Irregular change occurs for gap, can cause the defects of head sizes deform, dimensional accuracy is low, end face burr is big, product waste product
Rate is higher.
Utility model content
The technical problems to be solved in the utility model is that traditional multi-station progressive stamping mould pin head punching section has
Burr, contact pin uneven surface, product percent defective is high, low production efficiency, there is provided a kind of good product quality, head sizes deformation is small,
The secondary stamping and blanking mould that dimensional accuracy is high, end face burr is small.
In order to solve the above technical problems, the utility model uses following technical proposals：A kind of secondary stamping and blanking mould, bag
Punch-pin I, cavity plate I, cavity plate II and punch-pin II are included, punch-pin I is arranged on above cavity plate I, and punch-pin II is arranged on above cavity plate II, described
Punch-pin I and punch-pin II lower surface are matrix, and cavity plate I inner chamber is the Reentrant Cavity I being engaged with punch-pin I lower surface, recessed
Mould II inner chamber is the Reentrant Cavity II being engaged with punch-pin II lower surface.
Bullet block is provided with the Reentrant Cavity of the cavity plate I, spring is provided between bullet block and cavity bottom surface.
The utility model improves Dies ' Blanking blanking process structure, improves product quality；Be easy to ensure product size,
Product percent defective is reduced, production efficiency is improved, has saved labour cost.

Embodiment
As shown in Figures 4 to 6, the utility model includes punch-pin I1, cavity plate I2, cavity plate II5 and punch-pin II8, and punch-pin I1 is set
Putting above cavity plate I2, punch-pin II8 is arranged on above cavity plate II5, and the lower surface of the punch-pin I1 and punch-pin II8 are matrix,
Cavity plate I2 inner chamber is the Reentrant Cavity I21 being engaged with punch-pin I1 lower surface, cavity plate II5 inner chamber be with punch-pin II8
The Reentrant Cavity II51 that surface is engaged.Punch-pin I1 and cavity plate I2 is engaged, cavity plate II5 and punch-pin II8 is engaged so that pin
Portion needs the concave character type week leftover bits and pieces of material punching press simultaneously for being punched and is carried out in two steps, and reduces the generation of burr.
Bullet block 3 is provided with the Reentrant Cavity of the cavity plate I2, spring 4 is provided between bullet block 3 and cavity bottom surface.Bullet block 3 is set
Putting makes punch-pin I and cavity plate I clamp head scrap material jointly in punching, and punch-pin I highly calculates a reasonable size so that
Pin head waste material 6 is not completely separated from the material of slab band 7 during punching, and probably retain material thickness 1/3 ~ 1/2 does not separate；Simultaneously
Bullet block 3 is played a supporting role to cavity plate I2 inner chamber, and waste material is not completely separated from, and reduces the stamping press of this process, is enhanced recessed
Mould I intensity；Spring 4 is equipped with bullet block 3 so that punch-pin I has certain cushion space during punching, reduces under punch-pin I
The infringement on surface, increase punch-pin I service life.
The waste material on the head periphery punching press simultaneously when being punched pin head, the side extruding force of head on both sides is equal, can be with
Avoid the lateral displacement and deformation of material；Sheet Metal Forming Technology is punched at twice, is punched stampings for the first time and material strip is not complete
Pin head waste material, is separated half by separation with slab carrying material, and second of punching is again completely separated waste material and material strip, stays
The live part of lower pin head.Pin head is punched in two steps, and punch-pin I and cavity plate I fit clearances reduce and can greatly reduced
The burr of product section, waste material is removed by two times punch, make punching matter of the product head end quality substantially close to fine
Amount.
As shown in fig. 6, during production contact pin class product product, the effective process of mould totally 14 step, it is respectively：1. rush correcting hole,
2. correcting, 3. it is punched for the first time, is 4. punched for the second time, 5. falls waste material, 6. fall waste material, 7. fall waste material, 8. fall waste material, 9. drum pressure
Bag, I, bending II, detorsion I, detorsion II, cut-out are 10. bent, wherein 3. 4. process is respectively with process
First time punching in the utility model is punched with second, and the material left after the completion of secondary stamping and blanking on material strip is qualified
Pin head live part, then fall waste material process by 4 steps again, the bending of 2 steps and 2 step detorsions, it is qualified to produce
Contact pin class product.
