Detailed Description

The following description will be made in detail with reference to the accompanying drawings and specific embodiments for a cold stamping die for a plate reinforcing rib. The advantages and features of the present invention will become more fully apparent from the following description and appended claims. It should be noted that the drawings are in simplified form and are not to precise scale, and are provided for convenience and clarity in order to facilitate the description of the embodiments of the present invention.

The utility model provides a sheet metal cold stamping die with a plate reinforcing rib, which has the structure shown in figure 1 and comprises a to-be-processed plate 1, a male die 2 and a female die 3, wherein the male die 2 and the female die 3 are respectively positioned on the front and the back of the to-be-processed plate 1; under the combined action of the male die 2 and the female die 3, the plate 1 to be processed can form a plurality of reinforcing ribs 4 on the surface; the top end of the male die 2 is provided with a semicircular boss 6 for stamping the plate 1 to be processed; the female die 3 is provided with a plurality of semicircular grooves 5, and the semicircular grooves 5 can enable the reinforcing ribs 4 to be molded; the processing method comprises the steps that a destressing process through groove 8 is formed in each of two ends of the semicircular groove 5 on the plate 1 to be processed, the width of the destressing process through groove 8 is twice the thickness of the plate 1 to be processed, when the plate 1 to be processed is extruded to deform, the destressing process through groove 8 can offset the extrusion deformation of the plate 1 to be processed, and therefore the surface of the plate 1 to be processed is smooth.
