Abstract
The invention relates to a guiding mechanism of a punch die of acoustic components of automobiles. A chamfer block is arranged at an edge and corner portion of the lower end of a guide column seat; a guide column is fixed in the chamfer block of the guide column seat through a guide column fixing block; an upper wear-resistant block is fixed on a side wall of the chamfer block; a projection is arranged at a corner of the upper end edge of a guide sleeve seat; a guide sleeve is fixed in the projection of the guide sleeve seat through a guide sleeve fixing block and is matched with the guide column; and a lower wear-resistant block is fixed on a side wall of the projection and is matched with the upper wear-resistant block. The guiding mechanism of the punch die of the acoustic components of the automobiles is durable, compact and reasonable in structure and high in rigidity and strength; hundreds of thousands of guiding mechanisms can be produced; the number of surface scratches of the guiding mechanism is small; the guiding mechanism is wear-resistant; and cost on later maintenance and change can be reduced.
Description
Technical field
The present invention relates to a kind of guiding mechanism, the present invention especially relates to a kind of guiding mechanism of acoustic part of automobile die cutting die.
Background technology
At present, the acoustic part of automobiles such as automobile roof liner, carpet or hat rack are all larger products, after adopting clicking technique, mould is for ensureing rigidity, intensity, and die body generally adopts 45 steel, HT300, P20 etc., and the weight of whole mould is all very heavy, 4 ~ 5 tons at least, tens tons at most.In the service life of mould hundreds of thousands part, the guiding mechanism for mould proposes very high requirement, and the guiding accuracy requiring guiding mechanism enough is to ensure the stability of the die-cut edge of a knife.The stiffness and strength that the weight demands mould guide mechanism of tens tons is enough is simultaneously to ensure enough little distortion, and durability also needs to reach.Guide pillar guide pin bushing guiding single at present cannot ensure.First be durability, under the impact of so large weight, guide pillar guide pin bushing often deforms, a lot of cut in surface, serious wear.Secondly the guide pillar guide pin bushing guiding accuracy after wearing and tearing also cannot ensure.This all produces a very large impact the presentation quality product size of acoustic part of automobile product.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of and can meet high-precision requirement under high-strength high-voltage power, good tolerance the guiding mechanism of the acoustic part of automobile die cutting die in the service life of acoustic part of automobile mould hundreds of thousands part can be ensured.
According to technical scheme provided by the invention, the guiding mechanism of described acoustic part of automobile die cutting die, it comprises guide pillar seat, guide pillar, guide pillar fixed block, upper wear-resistant block, guide pin bushing seat, guide pin bushing, guide pin bushing fixed block and lower wear-resistant block; The lower-end corners portion of described guide pillar seat has scarce block, in the scarce block of guide pillar seat, be fixed with guide pillar by guide pillar fixed block, and this scarce block sidewall is fixed with wear-resistant block; The upper end corner of guide pin bushing seat has projection, and be fixed with guide pin bushing in the lug boss inside of guide pin bushing seat by guide pin bushing fixed block, guide pin bushing coordinates with described guide pillar, is fixed with lower wear-resistant block at the sidewall of this lug boss, and lower wear-resistant block coordinates with described upper wear-resistant block.
Guide pillar fixed block is fixed with guide pillar by pad fixed block and regulates pad.
Between the upper surface and guide pin bushing fixed block of guide pin bushing seat lug boss, be provided with guide pin bushing regulate pad.
Structure durable of the present invention, compact and reasonable, stiffness and strength of the present invention is better; The present invention can meet the production of hundreds of thousands part, and surface scratch is few, wear-resistant, and the present invention can reduce the expense that later maintenance maintenance is changed.

Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described.
The guiding mechanism of this acoustic part of automobile die cutting die, it comprises guide pillar seat 11, guide pillar 12, guide pillar fixed block 13, upper wear-resistant block 14, guide pin bushing seat 21, guide pin bushing 22, guide pin bushing fixed block 23 and lower wear-resistant block 24; The lower-end corners portion of described guide pillar seat 11 has scarce block, in the scarce block of guide pillar seat 11, be fixed with guide pillar 12 by guide pillar fixed block 13, and this scarce block sidewall is fixed with wear-resistant block 14; The upper end corner of guide pin bushing seat 21 has projection, guide pin bushing 22 is fixed with by guide pin bushing fixed block 23 in the lug boss inside of guide pin bushing seat 21, guide pin bushing 22 coordinates with described guide pillar 12, is fixed with lower wear-resistant block 24 at the sidewall of this lug boss, and lower wear-resistant block 24 coordinates with described upper wear-resistant block 14.
Guide pillar fixed block 13 is fixed with guide pillar by pad fixed block 15 and regulates pad 16.
Between the upper surface and guide pin bushing fixed block 23 of guide pin bushing seat 21 lug boss, be provided with guide pin bushing regulate pad 25.
In the present invention, guide pillar seat 11, guide pillar 12, guide pillar fixed block 13, upper wear-resistant block 14, pad fixed block 15 regulate pad 16 to be referred to as Guide column component with guide pillar; In the present invention, guide pin bushing seat 21, guide pin bushing 22, guide pin bushing fixed block 23, lower wear-resistant block 24 regulate pad 25 to be referred to as guide pin bushing assembly with guide pin bushing.
Assembling process of the present invention is as follows: first guide pillar 12 is installed on guide pillar seat 11, adopt close-fitting, guide pillar fixed block 13 adopts bolted on guide pillar seat 11, fixing for guide pillar 12, pad 16 is regulated by guide pillar to be placed on guide pillar fixed block 11 again, regulate pad 16 with the fastening guide pillar of pad fixed block 15, upper wear-resistant block 14 is installed to guide pillar seat 11 by bolt, the installation of whole guide pillar part; Guide pin bushing 22 is placed in the dowel hole of guide pin bushing seat 21, and guide pin bushing regulates pad 25 to be placed in guide pin bushing seat 21 surface, and be fixed with guide pin bushing fixed block 23, lower wear-resistant block 24 is installed to guide pin bushing seat 21 by bolt.
