Problems solved by technology

[0002] At present, the processing technology of the upper cover used in the fuel injection system of the automobile engine generally includes eight process steps of positioning, embossing, trimming, forming, trimming, shaping, punching and turning the hole. The process is relatively complicated, and each The process needs to be carried out by a special person, and two of them use the trimming process. The trimming process is easy to cause scraps and burrs on the material. After the scraps are generated, it needs to be reworked for surface treatment, otherwise the scraps will cause product appearance defects and low efficiency.

Embodiment approach 1

[0012] This embodiment provides a method for stretching and forming the upper cover of the fuel injection system of an automobile engine, which mainly includes the steps of positioning, embossing and embossing, forming, shaping, side punching and turning holes, specifically:

[0013] Positioning: that is, to position the blank 100 used to form the upper cover, so as to stabilize the position of the blank during subsequent processes.

[0014] Embossing and embossing: that is, embossing 101 and extruding ribs 102 on the above-mentioned material 100 at the same time; in the prior art, embossing and embossing are realized in two process steps respectively, and the present embodiment can be realized in one step.

[0015] Forming: stamping and stretching the material sheet 100 after embossing and embossing into a box-shaped material sheet.

[0016] Shaping: Reshape the surrounding sides 103 of the above-mentioned box-shaped material 100, and shape the surrounding sides 103 to be pe...

Embodiment approach 2

[0020] This embodiment provides a forming device used in the stretching method for the upper cover of the oil pool of the automobile engine fuel injection system in Embodiment 1, such as image 3 As shown, the forming device includes a feeding machine, a beading and beading mold, a forming mold, a shaping mold, a punching mold, a hole turning mold and product conveying equipment (not shown in the figure). The process sequence is arranged sequentially. After the feeder positions the material sheet 100 of the upper cover on the lower mold surface of the embossing and beading mold, the embossing and beading mold immediately makes a convex hull 101 on the material sheet 100 and extrudes ribs 102. Then, the semi-finished product after embossing and embossing is transferred to the molding die through the manipulator to change the mold, and the molding die stamps and stretches the material 100 into a box-shaped material 100 with side edges 103 around it, and the box-shaped material 10...

Abstract

The invention relates to the field of forming of upper covers, and discloses a drawing forming method and device for the upper cover of the oil sump of an automobile engine fuel injection system. The method comprises the following steps of (1) positioning the material piece (100) of the upper cover; (2) punching a convex hull (101) and pressing a rib (102) on the material piece (100); (3) carrying out punching and drawing on the material piece (100) to form a box; (4) carrying out shaping on the side edges (103) on the periphery of the material piece (100), and making the side edges (103) be perpendicular to the bottom of the box; (5) punching the side edges (103) to form side edge punched holes (104); and (6) carrying out hole flanging on the side edge punched holes (104). According to the drawing forming method and device for the upper cover of the oil sump of the automobile engine fuel injection system, compared with the prior art, no edge cutting technology is needed in the whole forming process, the material piece is prevented from generating burrs or scraps, the appearance of products is flawless, the technology is simple and can be completed mechanically and integrally, and the production efficiency is high.
