Detailed Description

The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1 to 4: a stamping die component for a semicircular sheet metal product comprises a male die mechanism and a female die mechanism which are matched, wherein the male die mechanism comprises a fixing plate 1, a discharging base plate 2 and a discharging plate 3 are sequentially arranged below the fixing plate 1, the female die mechanism comprises a female die plate 4, a first die, a second die and a third die are arranged in a matched manner with the male die mechanism and the female die mechanism, the first die, the second die and the third die are respectively composed of a set of forming male die and a set of forming female die, the forming male die is arranged in the male die mechanism, the forming female die is arranged in the female die plate 4,

the first die comprises a first forming male die 5 and a first forming female die 6 which are matched, the forming surfaces of the first forming male die 5 are of a symmetrical double-arc surface structure, the forming surfaces of the first forming male die 5 and the first forming female die 6 are tooth-shaped surfaces 7,

，K=

Wherein the value range of k is 3-5, t is the thickness of the processed plate, R is the radius of the cambered surface formed by the forming surface, and the depth of pressing the tooth tip of the sawtooth into the processed plate is H, then the following steps are provided: h =0.1-0.3 t.

The utility model discloses the working process to the stamping die subassembly of semi-circular panel beating goods as follows: the plate to be processed with the thickness t enters the stamping die under the action of the conveying mechanism, the plate firstly enters a stamping station of the first die, the first forming male die 5 and the first forming female die 6 stamp the plate and stamp the plate into a double arc shape (approximate to a W shape), and the forming surfaces of the first forming male die 5 and the first forming female die 6 are both special tooth-shaped surfaces 7, so that the plate can be directly formed into plastic deformation after stamping forming;

the plate advances a unit distance forward, the part which is punched into the double arc shape moves to a second die, the double arc part of the semi-finished product is punched for the second time by a second forming convex die 8 and a second forming concave die 9, because the forming surface of the second forming convex die 8 is of an arc surface structure, the double arc plate can be punched into the required arc shape in the secondary punching process, and because the forming surfaces of the second forming convex die 8 and the second forming concave die 9 are both special tooth-shaped surfaces 7, the plate can be directly formed into plastic deformation after punching;
