Abstract
The utility model discloses a kind of automobile side coaming stamping die, comprise punch and die, the shaping place of threshold of described punch and die is provided with L shape bending part, the inner side that described punch and die are positioned at L shape bending part is provided with a circle holding pad, position near L shape bending part on the holding pad of described punch is provided with technique convex closure, and the position near L shape bending part on the holding pad of described die is provided with the groove matched with technique convex closure.The utility model solves vehicle side plate stamping part L shape bending part problem easy to crack, and structure is simple, and cost is low, can be widely used in automobile side coaming stamping die field.
Description
Technical field
The utility model relates to automotive sheet punching press field, especially relates to a kind of automobile side coaming stamping die.
Background technology
Rapidly, auto output cumulative year after year, for enhancing productivity, each automobile production producer gradually adopts automatic stamping production line balance in Domestic Automotive Industry development in recent years.Mould is as the tooling device of automatic stamping streamline, and its stability determines the quality of production and the efficiency of streamline.In the design, the process such as processing and debugging of mould self, the technological design at mould initial stage is its core technology all the time, if technological design is unreasonable, the defects such as the cracking of plate, wrinkling, distortion, bounce-back will be brought, affect die table and plate quality, production line efficiency.
Wherein cracking is a large outstanding problem of stamping parts quality, especially the drawing cracking at stamping parts " L " shape position.As shown in Figure 1, the drawing die parting line border R at " L " shape position
die parting line7 than blank material border R
blank8 is large, and in drawing process, plate is by border R
blank8 to border R
die parting line7 direction motions, plate R footpath 9 increases gradually herein, and the blank on flange 10 can be subject to the acting in conjunction of radial tension and tangential stress, and produce biaxial tension distortion, stamping parts sidewall position is also subject to tangential stress effect, produces stretcher strain.In this process, if the too fast meeting of movement velocity of plate both sides, " L " shape position makes its R footpath 9 place feed supplement not enough, then can there is plate tension-thining excessive, produce cracking; If plate both sides movement velocity is unbalanced also can cause flange periphery place plate cracking, as shown in Figure 2.
In traditional Sheet Metal Forming Technology, the binder surface at stamping parts " L " shape position is plain edition, and be namely approximately plane, in drawing and moulding process, time descending, blank holder coordinates binder with die, and plate prolongs flowing through binder surface, bead to die layback.Due to the reason such as wearing and tearing of the fluctuation of plate material or punching production condition in actual production, mould molding position or bead, cause mould state to fluctuate, produce plate cracking defect.For this defect, conventional solution has: the position location etc. of the gap of on-line tuning blank holder balance weight, the air cushion pressure regulating press and adjustment plate; The height etc. of bead on blank holder is rectified and improved under line.But the measures to rectify and reform on these lines, under line, often bring the defect at other positions, the effect of pulling one hair and move the whole body, maintenance, the debugging cost of final cost are very large, are unfavorable for that automation line is produced.
Utility model content
The purpose of this utility model is to provide a kind of automobile side coaming stamping die, solves the problem of existing automobile side coaming punching press L shape bending part distortion easy to crack.
The utility model solves the technical scheme that its technical problem adopts: a kind of automobile side coaming stamping die, comprise punch and die, the shaping place of threshold of described punch and die is provided with L shape bending part, the inner side that described punch and die are positioned at L shape bending part is provided with a circle holding pad, position near L shape bending part on the holding pad of described punch is provided with technique convex closure, and the position near L shape bending part on the holding pad of described die is provided with the groove matched with technique convex closure.
Further, described technique convex closure is pyramidal structure, and the tip of pyramidal structure is near L shape bending part; The axis of described technique convex closure is vertical with the tangent line of L shape bending part bending part; The height of described technique convex closure is increased progressively to the other end by the tip of pyramidal structure.
The beneficial effects of the utility model: technique convex closure is set by the L shape bending part on stamping die, carry out the problem of the shaping feed deficiency of supplementary gusset plate L shape bending part, face is supplemented by the first punch forming on gusset plate of the technique convex closure on stamping die, then shaping L shape bending structure, in L shape bending structure is shaping, supplementary face continues to the feed supplement of L shape bending structure, prevents the problem of Cracking that L shape bending part feed supplement deficiency causes.Shaping complete after cut away supplementary face clout.
Below with reference to drawings and Examples, the utility model is described in detail.

Detailed description of the invention
Embodiment, as shown in Fig. 3 to 6, a kind of automobile side coaming stamping die, comprise punch 1 and die 2, the shaping place of threshold of described punch 1 and die 2 is provided with L shape bending part 3, the inner side that described punch 1 and die 2 are positioned at L shape bending part 3 is provided with a circle holding pad 4, and the position near L shape bending part 3 on the holding pad 4 of described punch 1 is provided with technique convex closure 5, and the position near L shape bending part 3 on the holding pad 4 of described die 2 is provided with the groove 6 matched with technique convex closure 5.Described technique convex closure 5 is pyramidal structure, and the tip of pyramidal structure is near L shape bending part 3.The axis of described technique convex closure 5 is vertical with the tangent line of L shape bending part 3 bending part.The height of described technique convex closure 5 is increased progressively to the other end by the tip of pyramidal structure.Described technique convex closure structure can do corresponding change according to the concrete analysis of CAE.
When punch and die close, technique convex closure is first shaping to put in place; Then shaping L shape bending part, the L shape bending part plate both sides material that can make full use of in technique convex closure carries out technique and supplements, and adjusts the material deficiency caused by plate charging rate inequality by the moulding of technique convex closure.Prevent the shaping rear cracking of L shape bending part.In later process, removed the process complementary surface at holding pad place by trimming shear.
