Embodiment Construction

[0032] The present invention is described in detail below in conjunction with accompanying drawing:

[0033] A stamping process for an automobile front floor, comprising the following three processes:

[0034] Drawing process; trimming and punching process; trimming, flanging and cutting process.

[0035] The parts of the front floor of the car are divided into two parts, left and right, most of which are symmetrical in shape. A single part is flanged on one side, similar to the shape of a factory and a glyph. The value of is under the condition of ensuring the strength of the trimming die, the smaller the value, the higher the material utilization rate.

[0036] In the drawing process, the value of the drawing depth d of the part should ensure that in the trimming and punching process, the flanging of the part is unfolded on the binder surface for trimming.

[0037] In the drawing process, a part of the product flanging fillet R1 is pulled out during drawing, and the die fi...

Abstract

The invention discloses a stamping process of an automobile front floor. The stamping process comprises the steps pf a drawing procedure, a trimming and punching procedure and a trimming, flanging andcutting procedure. In the drawing procedure, the overall drawing depth is designed to be small, the flanging of a part is directly unfolded on a material pressing face to be trimmed, the flanging circular bead R1 of the part is directly in transition circular bead R2 with the material pressing face, and no redundant technological supplementary modeling exists between the part and the material pressing face; and drawing ribs are not additionally arranged on the material pressing face, flowing of plate materials is controlled by adjusting the pressure of the material pressing face, or a drawingsill of a single-side step structure is selected, and flowing of the plate materials is controlled by adjusting the step number, the step shape and the fillet size of the step structure. According tothe stamping process, by reducing the distance s between a left part and a right part, reducing the overall drawing depth, canceling drawing process supplement, adopting the single-side step structure drawing ribs or canceling the drawing ribs and the like, the material utilization rate of the part is remarkably improved; and according to the stamping process, the material utilization rate is improved by 8%, and the cost of part raw materials is reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle engineering, in particular to a stamping process for an automobile front floor. Background technique [0002] The car front floor parts are generally divided into two parts, the left and the right connecting plate. The shape is simple and symmetrical. The traditional stamping process design is generally process 1 deep drawing, process 2 trimming and punching, process 3 trimming, flanging and cutting, such as Image 6 As shown, the process design of process 1 deep drawing is characterized by the fact that the part flanging is expanded on the process supplement, and trimming is performed in process 2, and there is redundant process supplement modeling between the trim line and the binder surface. After drawing forming, the excess process supplementary material is cut off in process 2, which makes the overall material utilization rate of the part low, resulting in unnecessary waste of cost. [0003]...
