Abstract
The invention discloses a method for processing a chain through hole by using a cold extrusion process. By the method, raw materials can be saved, the production cost can be reduced, and the quality of a product can be improved. The shape of the chain through hole is a cylinder with a central through hole. The method comprises the following steps of: firstly, blanking a round steel blank with a preset volume; secondly, roughly extruding the blank to obtain a roughly extruded piece with a blind hole at one end; thirdly, punching the piece to punch the blind hole of the roughly extruded piece; and finally, finely extruding the piece, loading the punched roughly extruded piece in a finely extruding die to perform fine extrusion molding and obtaining a chain through hole blank with a through hole. In the chain through hole produced by the method, the volume of a metal is plastically transferred on the premise of not damaging the performance of the metal, so the metal is shaped with few cutting processes and no cutting process; a large number of metal waste scraps formed in the cutting process are avoided; steel and various metal materials are saved; and the method has the advantages of high production rate, high precision and the like.
Description
Technical field
The present invention relates to the method for the logical cold-extrusion shaping of chain.
Background technology
Chain is logical to be a kind of industrial attachment, and it is the cylinder with central through hole; Chain traditionally is logical general to adopt turning and boring method manufacturing, and operation is various and difficulty of processing is big, efficient is low, and can cause with traditional manufacturing process and to cut the product weight of material weight after greater than moulding, promptly causes raw-material waste, cost increase.
Summary of the invention
Technical problem to be solved by this invention provides a kind of method of leading to the cold-extrusion technology machining chain, can save raw material, reduces production costs, and improves the quality of products; Chain is logical is shaped as the cylinder with central through hole; Technology of the present invention mainly may further comprise the steps:
Cold extrusion is a kind of plastic working technique, and it makes metal volume make plastic transfer under the prerequisite of not destroying metalline, reaches few cutting, does not have cutting and make metal forming; Form a large amount of metal debris when so just having avoided machining, save iron and steel and various metal material in a large number.
The chain that uses the present invention to make is logical, its production efficiency height, and the precision height can not adopt turning boring, cuts material weight product weight after the moulding no better than, and less waste material saves material greatly, reduces production costs; And cold extrusion makes metal material produce plastic deformation, and pulling force increases, and has improved the mechanical strength of product, has guaranteed product quality, makes product have more advantage on function of use.
Description of drawings
The present invention will be described in detail below in conjunction with accompanying drawing;
Fig. 1 is a procedure of processing of the present invention;
The specific embodiment
As shown in Figure 1; Present embodiment selects for use the PC100-5 chain logical, and its cold extrusion step is as follows:
At first be blanking, the round steel blank 1 of following predetermined;
Be thick extruding then, round steel blank 1 packed in the thick extrusion die that with the pressure of 500T, the speed of 3MM/S squeezes out the thick extrusion 2 of an end blind hole 21 behind the closed die; Carry out die sinking subsequently, with ejector beam the thick extrusion 2 that is shaped is ejected outside the mould after the die sinking; Be that thick extrusion process finishes;
Be punching again, after thick extrusion process finishes, then carry out the punching operation; Thick extrusion 2 is put into punching die, blind hole 21 usefulness drifts are washed into through hole 31, and obtain dumming spare 3;
Be smart extruding at last, the dumming spare after the punching 3 is packed in the smart extrusion die, under the pressure of 600T,, obtain the logical blank 4 of chain of through hole, promptly smart extrusion process completion of processing with the smart extruding of the speed dumming spare 3 of 3MM/S.
Use converted products of the present invention, can reach save time, effects such as saving of labor, material-saving and energy-saving and environmental protection, and in machining processes, improve work efficiency more than three times.
Claims (3)
1. with the logical method of cold-extrusion technology machining chain, its step is as follows:
Step 1, blanking, the round steel blank of following predetermined;
Step 2, thick extruding are packed blank in the thick extrusion die into, carry out thick extrusion molding, obtain the thick extrusion of an end blind hole;
Step 3, punching are put into punching die to thick extrusion, blind hole are dashed logical;
Step 4, smart extruding will be dashed thick extrusion after logical and be packed in the smart extrusion die, carry out smart squeezing shaping, and the chain that obtains through hole leads to blank.
2. according to claim 1 with the logical method of cold-extrusion technology machining chain, it is characterized in that: above-mentioned steps two is the pressure with 500T, and the speed of 3MM/S is slightly pushed the thick extrusion that obtains an end blind hole.
3. according to claim 1 with the logical method of cold-extrusion technology machining chain, it is characterized in that: above-mentioned steps four is the pressure with 600T, and the speed of 3MM/S is carried out the essence extruding, obtains the logical blank of chain.
