Description

Technical Field

[0001] The utility model belongs to the technical field of fasteners, and particularly relates to a forming die for making marks on multiple different surfaces of a fastener. Background Art

[0002] With the development of fastener design and manufacturing technologies, fasteners of different grades and structures are widely used. There are many types of fasteners with different shapes, and the same product may be produced by different manufacturers at the same time. When placing an order, new manufacturing requirements are put forward, requiring different marks to be made on different surfaces. For fasteners with such special-shaped structures, the production efficiency of making marks is low, and special marking tooling needs to be designed and manufactured separately, increasing production costs. For making marks on one surface, designing special tooling already increases costs and is inefficient. For making different mark contents on different surfaces, it is necessary to flip the part multiple times, debug the marking program multiple times, and there is a problem of inaccurate positioning during the flipping process, resulting in inconsistent mark positions during mass production, lower production efficiency, inconvenient use, and difficulty in meeting the mass production requirements of fasteners. Summary of the Invention

[0003] The purpose of the utility model is to overcome the above-mentioned drawbacks and provide a forming die for making marks on multiple different surfaces of a fastener, which can directly form several marks in one time by the die, with accurate positioning, unified positions, high production efficiency, fast mark forming, and convenient use.

[0004] The purpose of the utility model and the solution to its main technical problems are achieved by adopting the following technical solutions:

[0005] A forming die for making marks on multiple different surfaces of a fastener of the utility model includes a convex head, a protruding mark, and a die head. The characteristic is that the die head is trumpet-shaped and is provided with a plurality of convex heads integrally, and different protruding marks are arranged on the plurality of convex heads.

[0006] A through hole is arranged in the middle of the die head.

[0007] The convex head has an inclined plane protruding inward.

[0008] A die sleeve is sleeved outside the die head.

[0009] The protruding mark (3) should be parallel to the top surface of the convex head (2).

[0010] The protruding mark (3) is not less than 0.1 mm.

[0011] The protruding mark (3) is arranged in the middle of the inclined plane of the convex head (2).

[0012] Compared with the prior art, the utility model has obvious beneficial effects. From the above technical solutions, it can be seen that: several convex heads are integrally arranged in the horn-shaped mold head, and different protruding marks are arranged on the several convex heads. A through hole is arranged in the middle of the mold head. The convex heads protrude inward in an arc shape. A mold sleeve is sleeved outside the mold head. The fastener rod is inserted into the through hole arranged in the middle of the mold head. The several horn-shaped convex heads with inwardly protruding arcs correspond to several concave arc grooves on the conical fastener head. By hitting the mold head forcefully, several concave marks are punched out in the several concave arc grooves on the conical fastener head by the different protruding marks arranged on the several convex heads. At the same time, multiple marks are punched out, without the need for multiple flips and multiple debugging of the marking program. Moreover, the positioning is accurate, the marking positions are unified, the production efficiency is several times that of the previous one, meeting the mass production requirements of fasteners, realizing the direct one-time forming of several marks by the mold, with accurate positioning, unified positions, high production efficiency, rapid forming of marks, and convenient use.
