In the prior art, zigzag shape beam-like part (see figure 1) is usually from being shaped by direct binder or directly
Draw forming is connect to complete actual production, unavoidably needs to use zigzag shape beam-like part in automobile metal plate work.Due to tradition
Straight forming technique, the cambered surface that feature side-wall generates is serious, and product size is unable to reach entrucking requirement.
Therefore, it is necessary to repeatedly rectify and improve mold, causing to repair a die, the period is long, and processing cost is larger, and debugging cost is also very big, in vehicle
Body trial-production industry, which has had no advantage, to be sayed.
Summary of the invention
In view of the above defects of the prior art, the object of the present invention is to provide a kind of zigzag shape beam pieces to shape work
Skill and its two times punch mold, the method that can effectively solve the problem that zigzag shape beam piece Product Precision and fabrication cycle.
To achieve the above object, the present invention adopts the following technical scheme that：
On the one hand, a kind of zigzag shape beam piece forming technology, includes the following steps：
1) metal plate is pre-bended by numerical control bender, bending sequence is as follows：
1.1) first by the upward bending in metal plate left end end；
1.2) by the upward bending in metal plate right end end；
1.3) by left position downward bending close on metal plate middle section；
1.4) finally, by right end position downward bending close on metal plate middle section；
Numerical control bender point carries out bending to metal plate by above-mentioned 4 times, forms the process part processing of zigzag shape beam piece；
2) process part processing is placed in stamping die, carries out two times punch forming, obtains the final production of zigzag shape beam piece
Product.
In the step 1), the shaping amount of process part processing and final products is controlled within 3mm.
In the step 2), the side's of being provided with muscle in stamping die.
The process part processing depth is consistent with final products depth or < 2mm, and final products are compared at the angle R on process part processing
The upper big 2~5mm in the angle R.
On the other hand, a kind of zigzag shape beam piece shapes two times punch mold, including：Offer with outside zigzag shape beam piece
Shape is adapted the cavity plate of groove, and equipped with the punch-pin for being adapted convex block with cavity plate upper groove；
Along the two sides of the length direction of convex block on the punch-pin, it is equipped with to prevent process part processing from generating rebound in punching press
Square muscle；
The length of side's muscle is 15 ± 0.05mm, and the height of square muscle is 12 ± 0.05mm, and the angle R on square muscle is
R3 fillet.
In the above technical solution, a kind of zigzag shape beam piece forming technology and its two times punch provided by the present invention
Mold effectively solves product side wall and the phenomenon that cambered surface occurs, improves product size precision, and part production week is greatly saved
Phase, the punching press difficulty and springback compensation for reducing mold repair a die number.

Specific embodiment
Technical solution of the present invention is further illustrated with reference to the accompanying drawings and examples.
Incorporated by reference to shown in Fig. 2 to Fig. 6, a kind of zigzag shape beam piece forming technology provided by the present invention, including following step
Suddenly：
1) firstly, metal plate is pre-bended out product general shape by numerical control bender, bending sequence is as follows：
1.1) first by the upward bending in metal plate left end end；
1.2) by the upward bending in metal plate right end end；
1.3) by left position downward bending close on metal plate middle section；
1.4) finally, by right end position downward bending close on metal plate middle section；
Numerical control bender point carries out bending to metal plate by above-mentioned 4 times, forms the process part processing of zigzag shape beam piece；
2) process part processing is placed in stamping die again, carries out two times punch forming, obtains the final of zigzag shape beam piece
Product.
Preferably, the shaping amount of process part processing and final products controls within 3mm in the step 1).
Preferably, the process part processing depth is consistent with final products depth or < 2mm is advisable, the angle R on process part processing
It is 2~5mm bigger than the angle R on final products to be advisable.
Preferably, in the step 2), the side's of being provided with muscle in stamping die, rebound control when to two times punch forming
System.
The present invention also provides a kind of zigzag shape beam pieces to shape two times punch mold, including：It offers and zigzag shape beam
Like members shape is adapted the cavity plate 1 of groove 11, and equipped with the punch-pin 2 for being adapted convex block 21 with 1 upper groove 11 of cavity plate；
Preferably, being equipped with along the two sides of the length direction of convex block 21 to prevent process part processing in punching press on the punch-pin 2
When generate rebound square muscle 22；
Preferably, the length of side's muscle 22 is 15 ± 0.05mm, the height of square muscle 22 is 12 ± 0.05mm, square muscle
