Abstract
The present invention relates to a kind of automobile soft interior trim inclination cutting method, its innovative point is: first process upper and lower model face according to soft interior trim, inlays the chopping block with counterdie upper surface flush at the counterdie upper surface at the soft interior trim place of cutting; Again upper and lower mould is installed on upper and lower mould bases, and makes the chopping block at the soft interior trim place of cutting be tilted to outside; Top mold frame arranges die-cut hydraulic cylinder, die-cut hydraulic cylinder cutter; Die-cut Driven by Hydraulic Cylinder blade realizes inside gadget cut along moving perpendicular to chopping block surface direction to coordinate with chopping block.The contact of blade and chopping block has certain elastic range, and when the relative altitude of upper and lower mould has a small amount of deviation, just still can realize die-cut as long as blade can touch chopping block, therefore to the relative altitude of upper and lower mould, it requires that comparatively traditional approach is low; In addition, blade is not when returning upper limit, and parting matched moulds blade and counterdie also there will not be interference, avoids the damage of blade and mould.
Description
Technical field
The present invention relates to a kind of automobile soft interior trim cutting method, particularly a kind of required precision of upper and lower mould relative altitude size requires low and drift non-damageable automobile soft interior trim inclination cutting method.
Background technology
Automotive trim (Automotive Interior) mainly refers to the automobile product used by automotive interior repacking, relates to the every aspect of automotive interior, such as automobile sun film, automobile is shaken hands cover, Car floor mat, skid-proof pad of vehicles, cushion, foot pad etc. is all automotive trim product.Automotive trim system is the important component part of body of a motor car, and the design efforts would of interior decoration system accounts for more than 60% of car shape-designing workload, far exceedes car conour, is one of most important part of vehicle body.
Automotive trim is divided into hard interior trim and soft interior trim according to the difference of material, and the harder interior trim of soft interior trim has better feel and class, high-grade car uses more.The special soft interior trim of part needs the mode by tilting to cut to cut in the fabrication process, current soft interior trim tilts to cut with vertical to cut mode identical, as shown in Figure 1, die-cut hydraulic cylinder 7 is set in top mold frame 1 surface thereof, utilizes the drift 6 of die-cut hydraulic cylinder 7 end to coordinate with the counterdie edge of a knife a at counterdie 4 edge and realize cutting of soft interior trim 3.There is certain defect in this kind of inclination cutting structure: because die-cut direction is incline direction, and the relative altitude of top mold frame 1, lower mold holder 5 requires very high, otherwise easily cause product can't cut or counterdie edge of a knife a damages; If drift 6 is not rear spacing, can occur in the vertical direction interfering with the counterdie edge of a knife a when die sinking or matched moulds, and then cause mould or drift to damage.
Summary of the invention
The technical problem to be solved in the present invention is to provide the low and drift non-damageable automobile soft interior trim inclination cutting method of a kind of required precision of upper and lower mould relative size.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of automobile soft interior trim inclination cutting method, its innovative point is: described step is specially: first process upper and lower model face according to soft interior trim, inlays the chopping block with counterdie upper surface flush at the counterdie upper surface at the soft interior trim place of cutting; Again upper and lower mould is installed on upper and lower mould bases, and makes the chopping block at the soft interior trim place of cutting be tilted to outside; Top mold frame arranges die-cut hydraulic cylinder, and die-cut hydraulic cylinder is for driving the blade coordinating with chopping block and realize cutting, and the driving direction of die-cut hydraulic cylinder is perpendicular to chopping block surface; Die-cut Driven by Hydraulic Cylinder blade realizes inside gadget cut along moving perpendicular to chopping block surface direction to coordinate with chopping block.
Further, described die-cut hydraulic cylinder adopts slide block and slide cooperation to lead to blade.
The invention has the advantages that: when inside gadget tilts to cut, utilize the blade of inclination movement to coordinate with chopping block to realize, the contact of blade and chopping block has certain elastic range, within the scope of positive and negative 0.3mm, when the relative altitude of upper and lower mould has a small amount of deviation, just still can realize die-cut as long as blade can touch chopping block, therefore to the relative altitude of upper and lower mould, it requires that comparatively traditional approach is low; In addition, blade is not when returning upper limit, and parting matched moulds blade and counterdie also there will not be interference, avoids the damage of blade and mould.
Accompanying drawing explanation
Fig. 1 is that traditional automotive upholstery tilts to cut schematic diagram.
Fig. 2 is that in the present invention, automotive upholstery tilts to cut schematic diagram.
Detailed description of the invention
As shown in Figure 2, step is specially:
First process the profile of patrix 2, counterdie 4 according to soft interior trim 3, inlay the chopping block 9 with counterdie 4 upper surface flush at counterdie 4 upper surface at soft interior trim 3 place of cutting.In the present embodiment, minimum about the 15mm of thickness of chopping block, width about 20mm, chopping block can adopt brass or cast iron etc., hardness: HB110-HB150, by the Elastic Contact scope control of blade and chopping block 9 within the scope of positive and negative 0.3mm, then patrix 2, counterdie 4 to be installed on top mold frame 1, lower mold holder 5, and the chopping block 9 at the soft interior trim place of cutting is made to be tilted to outside.Certainly, it will be understood by those skilled in the art that chopping block 9 here outward-dipping be exemplary, be not circumscribed, can be adjusted to tilt to the inside according to actual conditions yet, repeat no more here.
Top mold frame 1 arranges the die-cut hydraulic cylinder 7 driving blade 6, so that blade 6 coordinates realization to cut with chopping block 9; Die-cut hydraulic cylinder 7 adopts slide block 8 and slide 11 to coordinate and leads to blade 6.The slide 11 of mounting strap slide block 8 in top mold frame 1, die-cut hydraulic cylinder 7 is arranged in slide 11, the piston rod end rushing but hydraulic cylinder 7 is connected with slide block 8, and slide block 8 installs blade 6 by blade pressuring plate 10, and blade 6 can be driven along moving perpendicular to chopping block surface direction by die-cut hydraulic cylinder 7.
Time die-cut, patrix 2 and counterdie 4 matched moulds are by soft interior trim 3 clamping and positioning, and die-cut hydraulic cylinder 7 drives blade 6 to realize inside gadget cut along moving perpendicular to chopping block 9 surface direction to coordinate with chopping block 9.
Claims (2)
1. an automobile soft interior trim inclination cutting method, is characterized in that: described step is specially:
