Description
Technical field:
The present invention relates to auto parts machinery production technical field, more specifically to a kind of automobile peace
Salient point mould in the full Webbing retractor progressive die.
Background technology:
At present, a lot of these parts of automobile all use continuous stamping die to produce, see Fig. 1,2
Shown in, existing a kind of automobile safety belt retractor A, its base plate forms several downward
Salient point A1.If using conventional process for stamping, lower mold arranges a recess, on
Drift is set on mould the base plate of coiler A is carried out salient point, then there is the salient point table rushed out
Face is rough, and when drift punching simultaneously is too fast, the stamping press to base plate is spent greatly, affects the strong of base plate
Degree problem, is exactly also the release problems of the progressive die.
Summary of the invention:
The purpose of the present invention is aiming at the deficiency of prior art, and provides a kind of car belt
Coiler salient point mould, its punching press bump surface smoothness out is good, complete at punching press salient point
Cheng Hou, the impact to coiler base plate is less, and material strip can preferably be deviate from from lower mold.
The technology solution of the present invention is as follows:
Automobile safety belt retractor salient point mould, including upper die and lower die, upper mold by upper bolster,
Upper mold upper padding plate, upper mold holder and upper molded plate composition, at least three upper mold nitrogen spring is fixed
On upper bolster, the piston rod of upper mold nitrogen spring and upper molded plate are bolted on one
Rise, together with upper mold upper padding plate is fixed by screws in upper mold holder, the work of upper mold nitrogen spring
Stopper rod sleeve is in the preset hole of upper mold upper padding plate and upper mold holder, and upper mold is got drift ready and is fixed on
On upper mold upper padding plate and upper mold holder, it is dome shape that upper mold gets the front end of drift ready, upper molded plate
On form upper mold and get drift ready through hole and material strip coiler blank accepting hole；
Material strip is placed between upper die and lower die, and lower mold is by die shoe, lower mold backboard and lower mold backing plate
Forming, lower mold backboard and lower mold backing plate are fixed by screws on die shoe, lower mold nitrogen spring
Being fixed on die shoe, the piston rod of lower mold nitrogen spring passes on lower mold backboard and lower mold backing plate
Preset hole and expose from the upper surface of lower mold backing plate, get module ready and be placed in lower mold backing plate and logical
Cross screw to be fixed together with lower mold backboard, get module ready and form several shrinkage pools, several
Shrinkage pool is first with several upper mold dotting punches one relative.
Described upper mold nitrogen spring has four, and lower mold nitrogen spring has four.
Described material strip coiler blank accepting hole has the shape matched with material strip coiler blank
Shape.
Described four lower mold nitrogen springs are separately positioned on four angles of square lower mold backboard.
Described module of getting ready has the upper surface shape that the base plate of blank with material strip is identical.
Described compression leg is fixed on upper mold upper padding plate and sleeve is in upper mold holder, and compression leg exposes
The lower surface of die clamp plate.
The beneficial effects of the present invention is:
Its punching press bump surface smoothness out is good, after punching press salient point completes, to coiler
The impact of base plate is less, and material strip can preferably be deviate from from lower mold.

Detailed description of the invention:
Embodiment: such as Fig. 3, shown in 4, automobile safety belt retractor salient point mould, including
Upper mold 1 and lower mold 2, upper mold 1 is by upper bolster 11, upper mold upper padding plate 12, upper mold holder 13
Forming with upper molded plate 14, at least three upper mold nitrogen spring 3 is fixed on upper bolster 11,
Together with the piston rod of upper mold nitrogen spring 3 is bolted on upper molded plate 14, upper mold
Together with upper padding plate 12 is fixed by screws in upper mold holder 13, the work of upper mold nitrogen spring 3
Stopper rod sleeve is in the preset hole of upper mold upper padding plate 12 and upper mold holder 13, and upper mold gets drift ready
15 are fixed in upper mold upper padding plate 12 and upper mold holder 13, and upper mold gets the front end of drift 15 ready
For dome shape, upper molded plate 14 forms upper mold and gets drift 15 ready through hole 151 and material strip
Coiler blank accepting hole 152；
Material strip B is placed between upper mold 1 and lower mold 2, and lower mold 2 is by die shoe 21, the lower mold back of the body
Plate 22 and lower mold backing plate 23 form, and lower mold backboard 22 and lower mold backing plate 23 are fixed by screw
On die shoe 21, lower mold nitrogen spring 24 is fixed on die shoe 21, lower mold nitrogen bullet
The piston rod of spring 24 is through the preset hole on lower mold backboard 22 and lower mold backing plate 23 and from lower mold
The upper surface of backing plate 23 exposes, and gets module 25 ready and is placed in lower mold backing plate 23 and passes through screw
It is fixed together with lower mold backboard 22, gets module 25 ready and form several shrinkage pools 251, if
It is the most relative that a dry shrinkage pool 251 gets drift 15 ready with several upper molds.
Described upper mold nitrogen spring 3 has four, and lower mold nitrogen spring 24 has four.
Described material strip coiler blank accepting hole 152 has and matches with material strip coiler blank
Shape.
Described four lower mold nitrogen springs 24 are separately positioned on four of square lower mold backboard 22
On angle.
Described module 25 of getting ready has the upper surface shape identical with the base plate of the blank of material strip B.
Described compression leg 16 is fixed on upper mold upper padding plate 12 and sleeve is in upper mold holder 13,
Compression leg 16 exposes the lower surface of upper mold holder 13.
Operation principle: material strip B is placed between upper mold 1 and lower mold 2, and upper bolster 11 is fixing
On the drift of punch press, upper bolster 11 moves downward when punching press, upper mold nitrogen spring 3
First being pushed up downwards by upper molded plate 14 allows upper molded plate 14 contact with material strip B, then by material strip B
Shifting onto on the piston rod of lower mold backing plate 23 and lower mold nitrogen spring 24, upper mold gets drift ready simultaneously
15 move downward and coordinate punching press on material strip B with several shrinkage pools 251 got ready in module 25
Go out salient point.It is in punching course, owing to upper mold gets the motion upper mold to be overcome of drift 15 ready
Nitrogen spring 3 elastic resistance, so upper mold gets drift 15 ready when being punched in material strip B, has one
Shorter buffer time, so can protect the salient point A1 smooth surface being up to.
Owing to the piston rod of lower mold nitrogen spring 24 is crushed under material strip B, when upper mold rises,
The material strip B jack-up demoulding will be facilitated material strip B to continuously by the piston rod of mould nitrogen spring 24
Lower one mould conveying of mould.
