Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1 and 2, in order to provide a forming method of a heat shield of a supercharger disclosed by the present invention, a cold stamping forming process is adopted, the forming method is suitable for forming a cover body 1 of the heat shield of the supercharger shown in fig. 1, the cover body 1 structurally comprises an outer circle profile 11 and a plane profile 13, the outer circle profile 11 is used for covering an outer circle part of the supercharger, and the plane profile 13 is used for covering an end surface part of the supercharger. The whole machining and forming process of the cover body 1 comprises a pre-forming stage, a trimming stage, a cutting stage, an excircle forming stage, a face forming stage and a punching stage.
Referring to fig. 3 and 4, the pre-forming stage is to process the new pre-forming piece 3 after integrally punching the material plate 2, and the overall shape of the new pre-forming piece 3 comprises the overall outline of the left cover 4 and the right cover 5. The new preform 3 comprises a new outer circle section 31 and a new plane section 32, the new outer circle section 31 can be finally processed into a left outer circle section of the left cover 4 and a right outer circle section of the right cover 5, and the new plane section 32 can be finally processed into a left plane section of the left cover 4 and a right plane section of the right cover 5. It should be noted that, when the flitch 2 is integrally punched and preformed, the forming arrangement directions of the left cover 4 and the right cover 5 are opposite, and because the left cover 4 and the right cover 5 are arranged oppositely during preforming, the left cover 4 and the right cover 5 are arranged in such a way in the forming process up to the cutting stage. The purpose that sets up like this can make punching press processing's in-process flitch 2 pressurized even, guarantees that the shaping of left side cover 4 and right side cover 5 is accurate, guarantees processingquality.
Referring to fig. 5, the trimming phase is carried out by trimming the excess peripheral scrap of the new preform 3, thus obtaining a web 6 of the left and right covers 4, 5 integrally joined. And simultaneously, processing and forming the novel excircle section 31 of the preformed piece, forming the left excircle contour 4111 of the left cover 4 and the right excircle contour 5111 of the right cover 5 in place, and forming the left heat insulation platform 4212 of the left cover 4 and the right heat insulation platform 12 of the right cover 5 in place, wherein the heat insulation platforms 12 extend out of the excircle.
Referring to fig. 6, the cutting stage forms two parts by punching the web 6 from the middle, thus obtaining the left and right independent covers 4 and 5. Two separate heat shields can be obtained by subsequent separate machining of the left and right shields 4, 5.
Referring to fig. 7, the new flat section 32 is machined and formed in a surface forming stage, and a left surface contour 43 of the left petaloid cover 4 and a right surface contour of the right cover 5 are formed in place, wherein the left surface contour 43 is schematically shown in the figure, and the right surface contour is arranged in a mirror image with the left surface contour 43.
Referring to fig. 8, in the punching stage, the machining of the through hole 14 is completed by punching the through hole 14 of the left cover 4 and the right cover 5 after the outer circle profile 11 and the surface profile are formed, wherein the through hole 14 of the left cover 4 is schematically shown in the drawing, and the through hole 14 of the right cover 5 is arranged in a mirror image mode with the through hole 14 of the left cover 4.
Referring to fig. 3 and 9, the forming method of the present invention is different from the conventional forming method in that the forming direction is changed from the stage of the preform processing.
Referring to fig. 3, in the pre-forming stage, the flitch 2 is processed into a pre-forming member, the pre-forming member includes an outer circle section and a plane section, the outer circle section becomes an outer circle contour 11 and a heat insulation platform 12 through a subsequent processing procedure, and the plane section becomes a plane contour 13 through the subsequent processing procedure.
Referring to fig. 9 and 10, the conventional old-fashioned preform 7 is processed by using the buckling surfaces of the female die and the male die in the die to process an old-fashioned planar section 72, and using the sides of the female die and the male die to process an old-fashioned outer circular section 71. The processing method enables the old-fashioned outer circle section 71 to be formed by vertically and directly stretching the material plate 2, and the processing method has the defect that galling can occur in the stretching process of the old-fashioned outer circle section 71 due to the fact that stretching is performed vertically and vertically, namely appearance flaws appear on the surface of the old-fashioned outer circle section 71. Meanwhile, the drawing causes the abrasion of the die-entering angle of the female die to be aggravated, and the manufacturing precision and the service life of the die are influenced.
Referring to fig. 3, the preforming method of the present invention is to process a new outer circle section 31 through the buckling surface of the female die and the male die in the die, and a new plane section 32 is processed through the sides of the female die and the male die. The processing method has the characteristics that no vertical wall is arranged in the forming process, the forming property is better, the galling phenomenon is avoided, and the surface quality of the part can be obviously improved. Because in the buckling process of the female die and the male die, the die and the flitch 2 are in contact with each other at a tangent point firstly, and then are changed into arc contact along with the continuous buckling of the die, the stretching stress is uniformly diffused, and the stress concentration is avoided.
The implementation principle of the embodiment is as follows: and placing the material plate 2 to a pre-forming stamping station, starting a stamping machine to drive the die to work, and buckling the female die and the male die. In the buckling process, a new outer circle section 31 of the cover body 1 is machined at the buckling position of the female die and the male die, a new plane section 32 of the cover body 1 is machined beside the female die and the male die until a new preformed piece 3 is machined after the forming is finished, and then the new preformed piece 3 is transferred to a trimming station. The edge cutting station carries out edge cutting processing, processes the excircle outline 11 and the heat insulation platform 12, and then transfers the continuous material 6 to the cutting station. The cutting station cuts the web 6 to obtain the left and right covers 4, 5, which are then transferred to the face forming station. The face forming station forms the left profile 43 of the left cover 4 and the right profile of the right cover 5 and then transfers them to the punching station. And the punching station punches the through hole 14 of the left cover 4 and the through hole 14 of the right cover 5, and finally, the forming process of the supercharger heat shield is completed.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
