Abstract
A heat shield butting-drawing forming structure comprises an upper heat shield (1) and a lower heat shield (2) and is characterized in that the upper heat shield (1) and the lower heat shield (2) are integrally formed in structure. The upper heat shield (1) and the lower heat shield (2) are connected into a whole through a big connecting opening (3). The heat shield butting-drawing forming structure realizes good arc uniformity at the semi-circular opening of a product, high product quality, and convenience in forming; the forming and the fitted butting of the upper heat shield and the lower heat shield can be realized by only one set of molds; the yield is improved to over 98% from the original lower 90%; the utilization rate of the materials is greatly improved; the rating of the materials is lowered by 18%; and the mold and working costs are obviously lowered.
Description
Technical field
The utility model relates to technical field of automobile parts, specifically is a kind of integrated thermal shield butt joint drawing and moulding structure.
Background technique
At present automobile exhaust system thermal shield part is made up of two thermal shields up and down, general thermal shield up and down all is separately moulding, need two molds to make, because moulding is made respectively, two big mouthfuls of circular arc degree conformity are relatively poor about making like this, the product of this shaping structure can take place because inconsistent causing of circular arc degree can not install when assembling, and because the amount of deformation on thermal shield material both sides is bigger, product design is irregular, clout is excessive during making, molding product is second-rate, causes the moulding up-to-standard rate low.
Summary of the invention
The utility model purpose is in order to overcome above-mentioned defective, integrated thermal shield butt joint drawing and moulding structure to be provided, adopting the thermal shield of this structure can guarantee product semicircular opening position circular arc conformity.
The technical solution of the utility model is:
A kind of thermal shield butt joint drawing and moulding structure comprises thermal shield and following thermal shield, and the described thermal shield of going up is a global formation structure with following thermal shield.
The described thermal shield of going up is connected to an integral body with following thermal shield by being connected big mouth.
Described connection is semicircle for big mouthful.
The semi-circular cut-out position that described connection is big mouthful is identical with the thermal shield semi-circle of last thermal shield and following thermal shield respectively.
The beneficial effects of the utility model are:
Thermal shield butt joint drawing and moulding structure of the present utility model, product semicircular opening position circular arc high conformity, the quality of product height, convenient formation, only need a mold just can realize the moulding and the butt joint that coincide of thermal shield up and down, yield rate is brought up to more than 98% by original less than 90%, and stock utilization is greatly improved, material consumption norm descends 18%, and die cost, operating cost all have obvious decline.
Description of drawings
Fig. 1 is a thermal shield butt joint drawing and moulding structural representation of the present utility model.
Among the figure: 1, go up thermal shield, 2, thermal shield down, 3, connect big mouthful, 4, the thermal shield semi-circle.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
A kind of thermal shield butt joint drawing and moulding structure comprises thermal shield 1 and following thermal shield 2, and last thermal shield 1 and following thermal shield 2 are a global formation structure.Last thermal shield 1 is connected to an integral body with following thermal shield 2 by being connected big mouthful 3.It is semicircle connecting big mouthful 3.The semi-circular cut-out position that connects big mouthful 3 is identical with the thermal shield semi-circle 4 of last thermal shield 1 and following thermal shield 2 respectively.
Embodiment recited above is described preferred implementation of the present utility model; be not that design of the present utility model and scope are limited; do not breaking away under the utility model design concept prerequisite; common engineers and technicians make the technical solution of the utility model in related domain various modification and improvement; all should fall into protection domain of the present utility model, the technology contents that the utility model is asked for protection all is documented in claims.
Claims (4)
1. a thermal shield butt joint drawing and moulding structure comprises thermal shield (1) and following thermal shield (2), it is characterized in that described upward thermal shield (1) and following thermal shield (2) are a global formation structure.
2. thermal shield butt joint drawing and moulding structure according to claim 1 is characterized in that the described thermal shield (1) of going up is connected to an integral body with following thermal shield (2) by being connected big mouthful (3).
