Description
Technical field
The utility model is related to mould applications, more particularly to a kind of flanging and restriking mold.
Background technology
Automobile industry is the industry of a high speed development, with the development of economy, also proposed higher for complete vehicle quality
Standard and requirement, the manufacturing technology of automobile die is also being continuously improved, such as automobile flanging die and shaping mould, flanging die
It is the product that a part of material of semi-finished product is generated to overturning with respect to another part material, shaping mould is by semi-finished product tune
For whole dimensional profile to improve the punch die of dimensional accuracy and surface smoothness, curring and sizing die is the critical process of automobile die design
One of, the flange on covering also increases the rigid of covering, makes covering edge in addition to the requirement of welding and assembly
It is smooth, neat and beautiful.
Many flanging and restriking molds are mostly two sets of independent molds in the market, and production when needs punching press twice, strikes out
This height extends the production cycle, and increases the expense of mold maintenance.
Invention content
The flanging and restriking mold low and with short production cycle the purpose of this utility model is to provide a kind of cost of stamping.
The purpose of this utility model is achieved through the following technical solutions：
A kind of flanging and restriking mold, including upper die holder and lower die holder, the upper die holder bottom surface middle part is equipped with upper mold core, described
Processing is fluted in the middle part of upper mold core, is equipped with location hole in groove, and the bottom surface of groove both sides upper mold core is equipped with limited block, in groove
Material drag core is installed, material drag core top surface be machined with the matched positioning pin of location hole and with the matched limit hole of limited block,
The side wall of material drag core is equipped with guide plate, and the lower die holder is equipped with lower mold core, and the quadrangle of lower mold core is equipped with knife tool, deburring
Cutter side is equipped with the positioning plate coordinated with guide plate, is equipped with multiple jacking blocks in the middle part of lower mold core, the bottom of each jacking block is connected with
The bottom of mandril, mandril is connect across lower die holder with spring.
The lower die holder of the lower mold core side is equipped with locating slot.
The utility model has the following effects that：
(1) by the way that the knife tool in lower mold core quadrangle is arranged, make workpiece can disposable punch forming, reduce and strike out
This；
(2) by the way that jacking block and mandril is arranged, so that workpiece is rapidly separated mold, shorten the feeding time；
(3) by the way that material drag core is arranged, so that workpiece is not shifted, improve machining accuracy.

Specific implementation mode
Embodiment
As shown in Figure 1 to 4, flanging and restriking mold provided in this embodiment, including upper die holder 1 and lower die holder 3, it is described on
Upper mold core 11 is equipped in the middle part of 1 bottom surface of die holder, 11 middle part processing fluted 12 of the upper mold core, groove 12 is interior to be equipped with location hole 13,
The bottom surface of 12 both sides upper mold core 11 of groove is equipped with limited block 14, and material drag core 2, the processing of 2 top surface of material drag core are equipped in groove 12
Have with 13 matched positioning pin 21 of location hole and with 14 matched limit hole 22 of limited block, the side wall of material drag core 2 is equipped with
Guide plate 23, the lower die holder 3 are equipped with lower mold core 31, and the quadrangle of lower mold core 31 is equipped with knife tool 32, knife tool 32 1
Side is equipped with the positioning plate 33 coordinated with guide plate 23, and 31 middle part of lower mold core is equipped with multiple jacking blocks 34, and the bottom of each jacking block 34 connects
It is connected to mandril 35, the bottom of mandril 35 is connect across lower die holder 3 with spring 36, and the lower die holder of 31 side of lower mold core is equipped with positioning
Slot 37 can quickly position workpiece by locating slot 37.
The application method of the utility model is：
Workpiece is placed on lower die holder 3 first, by the 37 quick lock in workpiece of locating slot on lower die holder 3, is then controlled
1 downlink of upper die holder processed, the material pressing core 2 for being subsequently fitted to 1 bottom of upper die holder are contacted with workpiece, and material pressing core 2 coordinates lower mold core 31 right
