Description
Technical field
The utility model relates to a kind of trial-production side shaping mould, is specifically related to a kind of vehicle body sheet metal trial-production side shaping mould.
Background technology
Trial-production requires with minimum cost, and the shortest cycle and higher quality standard complete the making of sample car or exemplar.
The manufacturing cycle of volume production diel is 8 ~ 12 months, and the manufacturing cycle of trial-production diel is about 45 ~ 60 days.The expense of body in white trial-production diel is about 5 ~ 10% of volume production die cost.Due to the difference of duration and cost, trial-production is larger with the technique difference of volume production.
During vehicle body sheet metal makes, the forming technology of most of part is a sequence drawing.Gusset, beater or beat-up etc. are owing to relating to side trimming, and be the part that technique is the most complicated, its cost the highest cycle is the longest.
Current volume production often adopts the assembling moulds such as wedge standard component to complete side trimming for side shaping, mainly contain lift-on/lift-off type, horizontal, tilting etc., its mould structure is complicated, and the buying manufacturing cycle is long, and cost is high.External trial-production often adopts the press with horizontal direction punching press, and mould structure can relative simplicity, but Design of Dies, punching press debugging are proposed to higher requirement and need to drop into special pressing equipment.
Summary of the invention
In order to solve the problems referred to above that prior art exists, the utility model proposes a kind of vehicle body sheet metal trial-production side shaping mould, under cycle and the controlled prerequisite of cost, common hydraulic press is utilized to realize the trial-production of side trimming, mould structure is greatly simplified, and cost and cycle all meet trial-production requirement.
The utility model is by the following technical solutions:
A kind of vehicle body sheet metal trial-production side shaping mould, it is characterized in that, comprise all round die holder, side correcting die, at least one clamp system, at least one detent mechanism, blank holder and punch, punch and blank holder are placed in above press lower bolster, and blank holder is positioned at the outside of punch, all round die holder is fixed on below press upper padding plate, side correcting die is fixed on below all round die holder, clamp system and detent mechanism are fixed on the correcting die sidewall of side, die and blank holder adopt outer guiding, guiding in blank holder and punch adopt.
As the improvement project of a kind of vehicle body sheet metal of the utility model trial-production side shaping mould, be provided with sky in the contact position of described side correcting die and blank holder and open avoiding structure.
The beneficial effects of the utility model: complete side trimming for existing pressing equipment; The use of all round die holder, part side trimming pressing direction is become from level and is vertically achieved, reduce the height of die body, and all round die holder can also be applied to follow-up similar mold use; Avoiding structure is opened by arranging sky on die, cannot the problem of back pieces or part deformation after eliminating side shaping; By using assembled but not the detent mechanism of die body and clamp system, improve positioning precision, reducing casting and numerical control processing technology difficulty; Owing to there is no the use of wedge standard component, reduce the workload of on-the-spot clamp die work assembling and setting, shorten trial-produce period, save trial-production die cost.

Detailed description of the invention
Below in conjunction with accompanying drawing, describe the technical solution of the utility model in detail by embodiment.
Consult Fig. 1 to Fig. 3, vehicle body sheet metal trial-production side shaping mould, comprises all round die holder 1, side correcting die 2, at least one clamp system 3, at least one detent mechanism 4, blank holder 5 and punch 6.Punch 6 and blank holder 5 are placed in above press lower bolster, and blank holder 5 is positioned at the outside of punch 6, all round die holder 1 is fixed on below press upper padding plate, side correcting die 2 is fixed on below all round die holder 1, clamp system 3 and detent mechanism 4 are bolted on side correcting die 2 sidewall, die 2 and blank holder 5 adopt outer guiding, and blank holder 5 and punch 6 adopt interior guiding.
Consult Fig. 4, be provided with sky in the contact position of side correcting die 2 and blank holder 5 and open avoiding structure, be specially side correcting die 2 and be provided with right angle chimb at the edge of itself and blank holder 5 contact position, and blank holder 5 is provided with slope chimb at itself and side correcting die 2 contact position, form certain interval at the edge, contact position of side correcting die 2 and blank holder 5 thus.The setting that sky opens avoiding structure can ensure that the part after the shaping of side is convenient interval, avoids " violence " to destroy part.
Consult Fig. 5, detent mechanism 4, be made up of alignment pin 7 and positioning support 8, alignment pin 7 is fixed in the circular groove on positioning support 8 top, is provided with multiple through hole bottom positioning support 8, is connected for carrying out bolt with side correcting die 2.
Consult Fig. 6, clamp system 3 is made up of binding clasp 9, rebound 10, profile support 11 and compact heap 12, and clamp system 3 supports 11 by profile and is connected with side correcting die 2 bolt.
The material of all round die holder 1, side correcting die 2, blank holder 5 and punch 6 is gray iron, and clamp system 3 and detent mechanism 4 can adopt cast iron or steel construction according to technique.
The operation principle of vehicle body sheet metal trial-production side shaping mould is as follows:
During Design of Dies, analyze the side reshaping structure feature of part, in conjunction with last sequence shaping form, judge the number of times needing side shaping, determine side shaping process pressing direction; According to part shape and drawing requirement, determine position and the quantity of clamp system 3 and detent mechanism 4, be bolted and be fixed on side correcting die 2 sidewall, and consider that the sky of rear side correcting die 2 pickup of shaping opens avoiding structure.
During die assembly, first punch 6 and blank holder 5 are placed in above the lower bolster of press, and carry out preliminary location, afterwards die 2 and all round die holder 1 are fixed on below press upper padding plate.Die 2 and blank holder 5 adopt outer guiding, and blank holder 5 and punch 6 adopt interior guiding, utilize above-mentioned guiding to complete the assembling of mould.
When mould uses, after first sequence drawing part needs to carry out preliminary deburring, adopt clamp system 3 and detent mechanism 4 that part is located on mould, householder method can be adopted to position the confirmation of precision simultaneously, when punching press closes, should be noted that part side shaping sky opens the play at position.
