Abstract
The utility model discloses a kind of automobile die drawing and puncture structure, comprise upper bolster and die shoe, upper bolster and die shoe two ends up and down between be provided with support component, line of symmetry position, die shoe centre position is provided with ring mode structure, for by workpiece jack-up, be arranged with multiple profile forming tank with R angle on ring mode structure both sides, described upper bolster lower surface has the bossing coordinated with die shoe profile forming tank; The shaping place of profile at the corresponding die shoe R angle of upper bolster is provided with and punctures structure.The utility model solves product drawing crack problem in large-scale workpiece one-off drawing process, reasonable in design, compact conformation, before the drawing crack of plate local location, technical face region near product is increased and puncture to reach the effect that once drawing goes out form panel, we can reduce mould structure cost in this case, production cost and cost of labor, also enhance productivity simultaneously.
Description
Technical field
The utility model relates to large-scale workpiece drawing and forming technical field, specifically belongs to a kind of automobile die drawing and punctures structure.
Background technology
Under present competitive environment, cost will be direct one of important indicator affecting Business survival, for existing Die & Mould Market, one or many is mostly adopted to stretch or locally-shaped mould structure for drawing workpiece forming mold, easily there is the situation of drawing crack in once drawing, multi-drawing or locally-shaped, causes production craft step more, mould amount increases, and adds production cost greatly undoubtedly.
Utility model content
For the problems referred to above, the purpose of this utility model there is provided a kind of automobile die drawing and punctures structure, solve product drawing crack problem in large-scale workpiece one-off drawing process, reasonable in design, compact conformation, increase technical face region near product before the drawing crack of plate local location and puncture to reach the effect that once drawing goes out form panel, we can reduce mould structure cost in this case, production cost and cost of labor, also enhance productivity simultaneously.
The technical solution adopted in the utility model is as follows:
A kind of automobile die drawing punctures structure, comprise upper bolster and die shoe, upper bolster and die shoe two ends up and down between be provided with support component, described line of symmetry position, die shoe centre position is provided with ring mode structure, for by workpiece jack-up, be arranged with multiple profile forming tank with R angle on ring mode structure both sides, described upper bolster lower surface has the bossing coordinated with die shoe profile forming tank; The shaping place of profile at the corresponding die shoe R angle of described upper bolster is provided with and punctures structure, described puncture structure by what be connected with upper bolster and puncture coupling part and puncture tip portion and form, puncture tip portion face and puncturing for 10mm between upper bolster lower surface, tip portion place foremost, die shoe is provided with and punctures tip portion insertion groove accordingly.
Described puncture between structure with upper bolster for insertion be fixedly connected with after by locked with bolts, this structure is convenient to puncture structure with changing, easy installation and removal according to different product is corresponding, enhances productivity and cost-saving.
Described puncture structure and also can be arranged on die shoe, or upper and lower die holder position is corresponding respectively arranges.
Compared with the prior art, the beneficial effects of the utility model are as follows:
The utility model, by walking material analysis to before drawing die drawing and forming, increases technical face region near product and punctures to reach the effect that once drawing goes out form panel before the drawing crack of plate local location.We can reduce mould structure cost in this case, and production cost and cost of labor, also enhance productivity simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is Figure 1A structure for amplifying schematic diagram.
Detailed description of the invention
See accompanying drawing, a kind of automobile die drawing punctures structure, comprises upper bolster 1 and die shoe 2, upper bolster 1 and die shoe 2 two ends up and down between be provided with support component 5, support component is hydraulic cylinder, line of symmetry position, die shoe 2 centre position is provided with ring mode structure 3, for by workpiece jack-up, be arranged with multiple profile forming tank 201 with R angle on ring mode structure 3 both sides, described upper bolster 1 lower surface has the bossing coordinated with die shoe profile forming tank, the shaping place of profile at the corresponding die shoe R angle of described upper bolster is provided with and punctures structure 4, described puncture structure 4 by what be connected with upper bolster and puncture coupling part 401 and puncture tip portion 402 and form, puncture tip portion 402 face and puncturing between upper bolster lower surface, tip portion place as 10mm foremost, die shoe is provided with and punctures tip portion insertion groove accordingly, describedly to puncture between structure 4 with upper bolster 1 as insertion is fixedly connected with, pass through locked with bolts puncturing between structure 4 rearward end and upper bolster 1, this structure is convenient to puncture structure according to different product is corresponding with changing, easy installation and removal, enhance productivity with cost-saving.Described puncture structure 4 and also can be arranged on die shoe, or upper and lower die holder position is corresponding respectively arranges; Drawing punctures the first jack-up of ring mode structure in structure, upper bolster drives and punctures mechanism and move downward together in the process moved downward, when upper bolster and die shoe are molded into end distance for about 10mm, puncture mechanism useless for product profile is punctured, prevent the useful profile of product (particularly R angle place) place or drawing breaking.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
