Description
Technical Field
The invention relates to the forging field, in particular to a method for processing a fixing clip and an upsetting die, wherein the fixing clip is a part on a mine lifting mechanism.
Background
As shown in fig. 1, the fixing clip for the mine hoist mechanism includes a body and a hook portion. The fixing clip part is a casting part in the past, but due to the inherent defect of the casting part, the part has the defects of sand holes, air holes and the like, so that the hook part 1 is easy to break, and casualties are caused. Therefore, the forging part is changed into the forging part, but according to the structural characteristics of the fixing clamp, the shape of the forging hook part is large in material requirement specification, the shape of the forging body is small in material requirement specification, and the difference between the shape of the forging hook part and the material requirement specification is large. The existing method is as follows: the selection specification is determined according to the hook part, and the blank for the main body part is freely rolled out on the air hammer by hand (the shape is shown in figure 2). The following disadvantages exist in using this method to manufacture the fixing clip: 1) The labor intensity of workers is high; 2) The blank is inconsistent; 3) The production efficiency is low; 4) Uneven material distribution, partial material shortage, folding and large scrapping amount of products.

Based on the method, the invention provides an upsetting die for processing a fixing clamp, which comprises an upper die and a lower die, wherein the upper die is formed by connecting and combining an upper die body and an upper die fixing plate and is fixed on a machine through a die shank, the middle part of the upper die body is provided with a material inserting hole which is matched with the outer diameter of a selected material blank, and the length of the material inserting hole is smaller than that of the material blank; the lower die comprises a lower die body and a lower die fixing plate, and the upper die can be close to the lower die under the action of a machine. When the upsetting press is used, the blank is inserted into the material inserting hole of the upper die body, a small section of the lower end of the blank is exposed, then the machine is started to drive the upper die and the blank to integrally descend, so that the lower end face of the blank abuts against the upper surface of the lower die body, and the exposed part of the blank is upset.
Preferably, the upper surface of the lower die body is a plane, and a groove corresponding to the material inserting hole is arranged in the middle of the upper surface.
Preferably, the arc transition is formed between the hole wall of the material inserting hole and the lower end surface of the upper die body.
Further, the die shank is connected with the upper die fixing plate to form a whole, a stepped hole coaxial with the material inserting hole is formed in the whole, the material inserting hole and the stepped hole are through holes, a punching rod and a jacking block are arranged in the stepped hole, and the punching rod can push the jacking block to enter the material inserting hole from the stepped hole. With the structure, after the upsetting of the blank is completed, the blank can be ejected downwards by using the rod and the ejector block.
In one embodiment, the lower die body is fixed to the lower die fixing plate by a lower die pressing plate.
In one embodiment, the upper mold body and the upper mold fixing plate are connected by screws.
The beneficial effects of the invention are as follows: because the specification of the selected blank is determined according to the size of the fixing clamp body during material selection, forging is not needed to be carried out on the body part, and the part of the blank can reach the material specification required by the shape of the hook part through upsetting the head part. By adopting the technical scheme of the invention, the defects of product shortage, folding and the like can be eliminated, and the qualification rate of finished products is high; the size consistency of the blank is good, and the material placing is convenient; and the labor intensity can be reduced, and the working efficiency is improved.
