Detailed Description

In order to make the objects, contents and advantages of the present invention clearer, the following description will make a detailed description of embodiments of the present invention with reference to the accompanying drawings and examples.

This embodiment provides a guard shield stamping forming mould, as shown in fig. 1 ~ 3, this stamping forming mould includes die 1, terrace die 2, upper die base 3, first lower mould 4, second lower mould 5, striker plate 6, stripper 7 and die holder 8.

Wherein, the upper surface of the male die 2 is provided with a boss structure, the male die 2 is positioned with a groove arranged on the lower surface of the upper die base 3 through the boss structure, and is fastened and connected through screws.

The female die 1 is arranged in a middle groove of the lower die holder 8, and the first lower die 4 and the second lower die 5 are respectively arranged on steps on two sides of the lower die holder 8. The female die 1, the first lower die 4 and the second lower die 5 are combined and positioned with the lower die base 8 through pins and are fastened and connected through screws. The material baffle 6 is fixed at different positions on the upper surfaces of the first lower die 4, the second lower die 5 and the lower die seat 8 through bolts according to the size of the blank, and is used for positioning the blank.

The stripper 7 welds the both sides central point of die holder 8 and puts, and the clearance between the stripper 7 after the assembly and the last mould part of constituteing by upper die base and terrace die is 1 ~ 2 mm.

The method for performing the punch forming of the protective cover by adopting the punch forming die comprises the following steps: respectively fixing an upper die holder 3 and a lower die holder 8 at corresponding positions on the upper working table surface and the lower working table surface of a machine tool; the blank material is put into an electric furnace to be heated to the required temperature, then taken out and placed on the upper surface of the female die 1, and is positioned by a plurality of material baffle plates 6; the main shaft of the press machine is rotated to drive the sliding block to drive the upper die part of the die to move downwards through a clutch switch of the machine tool, the blank is subjected to hot press forming under the action of the male die 2 and the female die 1, the hot press forming temperature is 900-930 ℃, the temperature and pressure are kept for 20-25 minutes after the press forming is finished, the sliding block of the machine tool drives the upper die part to move upwards, and the formed shield part is taken out of the die after being automatically dismounted by the discharge plates 7 on the two sides.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
