Problems solved by technology

[0005] The present invention designs a side trimming block, its manufacturing method and stamping die. The technical problem it solves is that there may be a step difference or offset between each side trimming block 12 when the stamping die is working, which leads to the stamping parts. The fillet R is not extended, but affects the quality of the workpiece

Embodiment Construction

[0024] Combine below figure 2 and image 3 , the present invention is further described:

[0025] A stamping die, mainly comprising a pressing core 25, a plurality of side integral knife blocks 22 and a wedge base 24, the plurality of side integral knife blocks 22 form a strip-shaped knife block group, and the strip-shaped knife block group is located on the press core 25 and the wedge base 24, there is a groove at the junction of two adjacent side whole knife blocks 22, and the two parts of the groove are respectively distributed on the two adjacent side whole knife blocks 22, in the groove A positioning key 23 is installed, and two adjacent side whole knife blocks 22 are fixed into one piece by the positioning key 23, so as to avoid step difference or offset between each side whole knife blocks 12 .

[0026] The fixing method is as follows: two screw holes are provided on the positioning key 23, and the two screw holes correspond to the original screw holes on the adjacen...

Abstract

The invention relates to a side fishing cutter block and a manufacturing method thereof as well as a stamping die. A groove is formed at the joint between adjacent two side fishing cutter blocks (22); two parts of the groove are distributed on the adjacent two side fishing cutter blocks (22) respectively; a positioning key (23) is mounted in the groove; and the adjacent two side fishing cutter blocks (22) are fixed into an integral member through the positioning key (2) so as to avoid section difference or deviation between the side fishing cutter blocks (12). In the invention, by adding a positioning key between the existing adjacent two side fishing cutter blocks, the functional requirements of a die are met, the unsmooth phenomenon from the plate to the local part due to the side forceof the side fishing cutter blocks is solved, and the post-debugging cost is reduced.

Description

technical field [0001] The invention relates to the technical field of stamping manufacturing process equipment, in particular to a side trimmer block, a manufacturing method thereof and a stamping die. Background technique [0002] Stamping molds for casting cover parts are the most demanding, difficult to process and safest molds in automobile body manufacturing. Cover parts are directly related to the quality of the body-in-white, and are problems that can be found at a glance in the product. Appearance and matching are not allowed A little flaw, or once it is exposed, will have a great impact on the sales and brand of the entire product, so the stamping process is very demanding. [0003] Such as figure 1 As shown, the current stamping die block installation process is as follows: the existing stamping die is composed of multiple side block blocks 12, and the side block blocks 12 are separated, and each side block block 12 is formed by bolts 13 and pins. Fixed in the m...
