Detailed Description

The invention will be further described with reference to the accompanying drawings, without limiting the scope of the invention to the following:

as shown in fig. 4 to 7, the R-angle cracking prevention rigid convex mold comprises a forming female mold 10 and a forming male mold 11, wherein arc grooves a12 are formed in the bottom surface of the forming male mold 11 and located on the left side and the right side of the forming male mold, an arc chamfer a13 is arranged at the contact position of the bottom surface of the forming male mold 11 and the arc groove a12, a concave cavity 16 is formed in the top of the forming female mold 10, the concave cavity 16 is arranged under the forming male mold 11, an arc chamfer B14 is arranged between the top surface of the forming female mold 10 and the side wall of the concave cavity 16, the arc chamfer B14 is matched with the arc groove a12, an arc groove B15 is arranged between the side wall of the concave cavity 16 and the bottom wall of the concave cavity 16, and the arc groove B15 is matched with the arc chamfer a 13.

The die further comprises a material pressing block 5, a guide groove is formed in the material pressing block 5, the forming male die 11 is slidably mounted in the guide groove, and the two arc grooves A12 are arranged in a bilateral symmetry mode. The two arc chamfers A13 are arranged symmetrically left and right.

The working process of the utility model is as follows:

the worker firstly places a plate on the top surface of the forming female die 10, and ensures that the plate is positioned right above the cavity 16, then the worker presses the pressing block 5 on the top surface of the plate to realize the fixture fixing of the plate, then the forming male die 11 is pressed downwards, the lower end part of the forming male die 11 penetrates through the guide groove of the pressing block 5 and presses on the top surface of the plate, the pressed material of the plate is extended into the cavity 16, when the arc groove A12 of the forming male die 11 is completely buckled with the arc chamfer B14, and simultaneously the arc chamfer A13 of the forming male die 11 is completely buckled with the arc groove B15, a rigid convex part can be extended between the forming female die 10 and the forming male die 11.

Because the upper R surface 8 of the formed rigid-convex part is formed under the buckling of the arc groove A12 and the arc chamfer B14, and the lower R surface 9 is formed under the buckling of the arc chamfer A13 and the arc groove B15, the upper R surface 8 and the lower R surface 9 are not formed in an open state, and the cracking of the upper R surface 8 and the lower R surface 9 of the rigid-convex part is effectively avoided, so that the service life of the rigid-convex part processed by the rigid-convex part is obviously longer than that of the rigid-convex part processed by a traditional stamping die.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
