Description
Technical field
The invention belongs to punch forming technical field, more specifically to a kind of striking out for automobile absorber skeleton
Type method.
Background technology
Automobile absorber skeleton is the supporting rack of automobile absorber, more demanding to toughness, and skeleton also needs to and rubber
Glue part is compound, and skeleton structure is relatively also more complicated, there is tapered portion, flange.
The molding of skeleton at present is that the punching press largely used combines to produce with machining, but mach production
Period is longer, causes production cost higher, and carries out being susceptible to situation about splitting if flange after machining again, and bores
Shape portion is also easily deformed, and causes yield rate relatively low, cost is higher.
Invention content
The technical problem to be solved by the present invention is to provide a kind of impact forming method of automobile absorber skeleton, not need to
Machining, using punching press and extrusion forming, the production cycle is shorter and yield rate is higher.
The present invention technical solution be to provide a kind of impact forming method of automobile absorber skeleton, it include with
Lower step：
1) Blanking：The Blanking on Blanking machine；
2) it stretches：Blank is stretched to height as 48 ± 0.2mm, a diameter of 57 ± 0.1mm；
3) it rushes to summit hole；
4) integer：Carry out stretching integer on stretching-machine, the height of blank is 62.1 ± 0.1mm after integer；
5) expand suitable for reading：The height that blank expands part suitable for reading is 25.1 ± 0.5mm, and flaring while is carried out using Hough mechanism
It holds tightly, with the tapering of preliminary shaping blank, and by lower 10 °~50 ° of mouth flange, the whole height of blank is controlled in 53 ± 0.2mm；
6) whole suitable for reading and flange：The height that whole rear blank suitable for reading expands part suitable for reading is 25.1 ± 0.2mm, while whole suitable for reading
Second is carried out using Hough mechanism to hold tightly, with the tapering of complete shaping blank, and by lower mouth flange to 90 ° of formation bottom surfaces, base
The whole height of material is controlled in 53.2 ± 0.2mm；
7) bottom outlet is rushed：It is punched out six through-holes simultaneously in bottom surface；
8) trimming：The extra side in bottom surface is cut away, while the notch of three arcs is cut out in bottom surface, cubing is first used before trimming
It is tested using the through-hole on bottom surface as location hole, rejects deformable member；
9) bottoming is convex：In the through hole of bottom surface six, it is convex to go out bottom, and six positions is also required to be carried out at the same time, whole after processing
Highly control is in 53.5 ± 0.2mm；
10) fabrication hole is rushed：Four fabrication holes are gone out in tapering, four fabrication holes are evenly distributed；It is also gone out at place suitable for reading
Four fabrication holes, four fabrication holes are equally evenly distributed；
11) jet-bedding：Six open slots are gone out in end suitable for reading, six open slots are evenly distributed；
12) test package：Product inspection after step 11) is processed is packed.
By lower 20 °~40 ° of mouth flange in step 5), and the busbar in tapering that is formed after Hough mechanism holding and axis
Angle is the half of the angle of the busbar and axis in tapering after complete molding, after such method, can improve tapering into
Stability after type, and flange is also easier to, the breakage rate of flange further reduces.
By in step 5) by lower 30 ° of mouth flange.
Four fabrication holes in tapering and four fabrication hole stagger settings at place suitable for reading in step 10), after setting in this way so that
The punching of fabrication hole will not lead to the insufficient situation of intensity occur, while be rubber parts compound tense between fabrication hole, can also rise
To under the action of bonding strength between increase and rubber parts.
Four fabrication holes at place suitable for reading and six open slot stagger settings in step 11) in step 10)；Then setting in this way
Afterwards, it may be such that the intensity of open slot is relatively high, be less prone to the situation of tear, the use of the skeleton of guarantee in use
Intensity.
After above method, compared with prior art, the present invention has the following advantages：
1st, since the present invention has also carried out flange using Hough mechanism while expanding suitable for reading to be molded tapering, and tapering and
Flange is just molding by twice technique, this allows for tapering and is easier to be molded, and be not easy in flange cracking
Situation；
2nd, trimming and bottoming are convex again after bottom outlet is rushed, it is easy to produce in this way during inspection, while also allow for positioning, into
And trimming and the convex accuracy of bottoming can be improved, improve yield rate；
3rd, the setting of eight fabrication holes can effectively eliminate the problem of stress concentration after expansion mouth and tapering processing, so as to
Improve the toughness of product.
4th, whole process does not need to machine, and the production cycle is shorter, and production efficiency is high, and production cost can be greatly reduced.
