Abstract
The invention discloses a kind of manufacturing process of brake caliper.The technical scheme is that：A kind of manufacturing process of brake caliper, including steel plate strip and stamping machine, the spline drift for 30 keys that the stamping machine includes the second round punch that the first round punch, the radius that radius is r are r+d and radius is r+d+e, PVD processing is done in the outer surface of first round punch, the second round punch and spline drift, and punch steps include：1）, using the first round punch the first pre-punched hole is stamped out on steel plate strip；2）, using stamping out the second pre-punched hole on the basis of the first pre-punched hole of second round punch on steel plate strip；3）, 30 tooth precision stamping holes are stamped out on the basis of the second pre-punched hole of steel plate strip using spline drift.The accurate complete and finish of scheme spline provided by the invention is more than 80%.
Description
Technical field
The present invention relates to auto-parts production technical field, more particularly to a kind of manufacturing process of brake caliper.
Background technology
The automobile using brake caliper product of prior art, spline is designed as generally 18 toothings, but occurs some
Vehicle finds that pull bar and bolt position gap are larger after entrucking checking, influences brake caliper parking power size, it is therefore desirable to set
The brake caliper more than 18 toothings is counted out, it is demonstrated experimentally that the brake caliper of 30 toothings, referring to the drawings 1, can be effectively improved
Product gap, solve the problems, such as that clamp parking power is unstable, but the punching press of the brake caliper product for producing 30 toothings
Required precision is higher, and the manufacturing process occurred in the prior art is all difficult to ensure that product quality is stable.Specifically, prior art
The shortcomings that product of fabrication process occurs is, first, 30 tooth splines, in punching press, because spline is densely distributed, drift is smart
It is difficult that can reach finish requiring on 80% after punching, because euphotic belt is more, assembling fitness is better, but the technique of punching press
Difficulty is bigger, in the prior art substantially 40% ~ 50% or so；Second, when the spline punching press of 30 teeth, due to densely distributed, flower
Key is difficult 100% to come out, and can influence assembly precision.
The content of the invention
It is in view of the deficienciess of the prior art, accurate complete and bright and clean it is a primary object of the present invention to provide a kind of spline
The manufacturing process of brake caliper of the degree more than 80%.
To achieve the above object, the invention provides following technical scheme：A kind of manufacturing process of brake caliper, including steel
Strip and stamping machine, the stamping machine include radius be r the first round punch, radius be r+d the second round punch and
Radius be r+d+e 30 keys spline drift, the outer surface of first round punch, the second round punch and spline drift
PVD processing is done, punch steps include：
1）, using the first round punch the first pre-punched hole is stamped out on steel plate strip；
2）, using stamping out the second pre-punched hole on the basis of the first pre-punched hole of second round punch on steel plate strip；
3）, 30 tooth precision stamping holes are stamped out on the basis of the second pre-punched hole of steel plate strip using spline drift.
Preferably, the scope of the d is between 0. 2 ~ 1mm.
Preferably, the scope of the e is between 0.01 ~ 0.1mm.
Preferably, the quantity of first round punch, the second round punch and spline drift is two and equal energy
It is enough to sweep away out two punching holes up and down on steel plate strip simultaneously.
It is of the invention to be had the following advantages that relative to prior art, the manufacturing process of a kind of brake caliper of the invention, in flower
The fit clearance of key drift and mold insert does accurate point, while the first round punch, the second round punch and spline punch head surface
Do PVD processing, it is ensured that material hardness reaches enough requirements, is so able to ensure that the tooth form of spline and can come out, and produces in batches
It is stable.
Before punching press spline, two step pre-punched holes are first done, the first pre-punched hole is simple punching, and the second pre-punched hole is fine,
It may insure that extrusion fracture face reaches 80% ~ 90%, the light of 30 tooth splines of product so may insure in shock wave keyhole
Band can reach more than 80%.
Brief description of the drawings
Fig. 1 is the system that the spline of the brake caliper that the spline of prior art is 18 toothings and this programme is the structure of 30 teeth
The structural representation of moving calipers；
Fig. 2 is that the first round punch, the second round punch and spline drift carry out the structural representation after punching press on steel plate strip
Figure.
In figure：1st, steel plate strip；2nd, the first pre-punched hole；3rd, the second pre-punched hole；4th, 30 tooth precision stamping hole.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of manufacturing process of brake caliper, including steel plate strip 1 and stamping machine, the stamping machine include half
The spline drift of the second round punch that the first round punch, the radius that footpath is r are r+d and 30 keys that radius is r+d+e, institute
PVD processing is done in the outer surface for stating the first round punch, the second round punch and spline drift, and punch steps include：
1）, the first pre-punched hole 2 is stamped out on steel plate strip 1 using the first round punch；
2）, using stamping out the second pre-punched hole 3 on the basis of the first pre-punched hole 2 of second round punch on steel plate strip 1；
3）, using spline drift 30 tooth precision stamping holes 4 are stamped out on the basis of the second pre-punched hole 3 of steel plate strip 1.
A kind of manufacturing process of brake caliper of the present invention, does accurate point, together in the fit clearance of spline drift and mold insert
When the first round punch, the second round punch and spline punch head surface do PVD processing, it is ensured that material hardness reach enough will
Ask, being so able to ensure that the tooth form of spline can come out, and produce in batches stable.
Before punching press spline, two step pre-punched holes are first done, the first pre-punched hole 2 is simple punching, and the second pre-punched hole 3 is essence
Punching, it can be ensured that extrusion fracture face reaches 80% ~ 90%, and the light of 30 tooth splines of product is so may insure in shock wave keyhole
Bright band can reach more than 80%.
Preferably, the scope of the d is between 0. 2 ~ 1mm.
Preferably, the scope of the e is between 0.01 ~ 0.1mm.
Preferably, the quantity of first round punch, the second round punch and spline drift is two and equal energy
It is enough to sweep away out two punching holes up and down on steel plate strip 1 simultaneously.Double-piece processing can be carried out on steel plate strip 1 simultaneously by so setting
Shaping, accelerates production efficiency.
Described above is only the preferred embodiment of the present invention, and protection scope of the present invention is not limited merely to above-mentioned implementation
Example, all technical schemes belonged under thinking of the present invention belong to protection scope of the present invention.It should be pointed out that for the art
