Abstract
The invention provides a method for manufacturing stainless steel handle cores. The method includes heating stainless steel disc wires before cold heading is carried out; molding heated materials by the aid of cold heading machines to obtain blanks; finely machining the blanks to obtain finished products. The method has the advantages that technological steps are simple, the production efficiency is high, and the cost can be lowered; the products manufactured by the aid of the method are high in compressive strength, torque and density and excellent in mechanical property and are durable, and the like.
Description
Technical field
The present invention relates to handle fuse preparing technical field, refer to a kind of preparation method of stainless steel handle fuse especially.
Background technology
Sintered metal product has been mixed into non-metal powder with metal dust as: Tie Fen ﹑ Tong Fen ﹑ stainless steel powder etc. comprises) for raw material, to produce by shaping-sintering process, traditional technological process is: batch mixing-compacting-sintering-shaping-post processing, namely first by the highly purified mixed powder dress of preparation and mould, shape is made in certain pressure, then by pressed compact in controlled atmosphere generator, sinter at the temperature lower than matrix material fusing point, make to form metallurgical binding between powder particle.This technique tool has the following advantages: 1. do not need or only need minute quantity machining, 2. the material rate of diverting from one use to another can up to 97%, 3. the manufacturing tolerance of accessory size is less and have repeatability, 4. material composition is adjustable, and 5. piece surface fineness is better, 6. improves intensity and wearability by heat treatment, 7. self-lubricating or filtration are used, the material or goods with controlled porosity can be provided, 8. can manufacture that other metal forming technologies can not manufacture, complex-shaped or peculiar part.But the obtained fuse of above-mentioned technique has anti-pressure ability difference, bear the shortcomings such as the little and density of moment of torsion is low.
Summary of the invention
The present invention proposes a kind of preparation method of stainless steel handle fuse, solve handle fuse anti-pressure ability in prior art poor, bear the little and low density problem of moment of torsion.
Technical scheme of the present invention is achieved in that
A preparation method for stainless steel handle fuse, comprising:
(1) heat before stainless steel disk silk being carried out cold pier;
(2) it is shaping that the material after step (1) being heated carries out Cold header, obtains blank; Wherein pressure is 130-170 ton;
(3) finished product is obtained by after above-mentioned blank fine finishining.
As preferred technical scheme, before described step (1) cold pier, the temperature of heating is 800-1000 DEG C.
As preferred technical scheme, before described step (1) cold pier, the temperature of heating is 900-950 DEG C.
As preferred technical scheme, in described step (2), pressure is 145-160 ton.
As preferred technical scheme, the shaping concrete steps of described Cold header are as follows:
A, the first die stamping are shaping;
B, the second die stamping length;
C, the accurate length of the 3rd die stamping;
D, the 4th stamping aperture;
E, the 5th mould are washed into type bias four square hole of product;
Chamfering in f, the 6th mould;
G, the 7th stamping perforation.
Beneficial effect
(1) the present invention adopts stainless steel disk silk to be easy to processing, enhances productivity; Adopt that Cold header is shaping has the fast advantage of processing technology;
(2) processing step is simple, production efficiency is high;
(3) the product resistance to compression obtained through present invention process is about 8 tons, torque resistant is about 5 tons, and therefore compression strength is high, moment of torsion is large, mechanical performance is strong, density advantages of higher, durable in use.
Accompanying drawing explanation
In order to be illustrated more clearly in embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1, process chart of the present invention.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
The invention discloses a kind of preparation method of stainless steel handle fuse, adopt dusty raw materials different from traditional handicraft, the present invention adopts that stainless steel disk silk heats before cold pier, Cold header is shaping and fine finishining obtains finished product.Preparation method of the present invention is completely different from traditional handicraft, and the material wherein used is all commercially available materials be easy to get, and the machine of use is multi-functional position Cold header (peak machinery production is grasped in Taiwan).
Embodiment 1
A preparation method for stainless steel handle fuse, comprising:
Step S1,304 stainless steel disk silks are carried out cold pier before heat; Wherein before cold pier, the selectable temperature range of heating is 800-1000 DEG C, and preferable range is 900-950 DEG C, and the temperature chosen in the present embodiment is 950 DEG C.
Step S2, step S1 is heated after material to carry out Cold header shaping; The selectable scope of pressure is wherein 130-170 ton, and preferred scope is 145-160 ton, chooses 150 tons in the present embodiment.
Concrete steps are as follows:
A, the first die stamping are shaping;
B, the second die stamping length;
C, the accurate length of the 3rd die stamping;
D, the 4th stamping aperture;
E, the 5th mould are washed into type bias four square hole of product;
Chamfering in f, the 6th mould;
G, the 7th stamping perforation;
Then blanking obtains blank;
Above-mentioned material enters the thimble of the front end of " under cut mould " of machine, automatically controls length, then after being cut off by " flat mouth cutter ", position, school is to the first die orifice automatically, and sending into the first mould by the first mould die orifice by first punching rod, to carry out punching press raw material shaping; Then first to the 7th by that analogy, until finished product.
Step S3, by after above-mentioned blank fine finishining finished product.Accurately machined technique is that prior art does not repeat again.
Above-mentioned preparation method's processing step is simple, and production efficiency promotes more than 1 times than adopting powder mode; And cost reduces.The product resistance to compression obtained through above-mentioned technique is about 8 tons, torque resistant is about 5 tons, and therefore compression strength is high, moment of torsion is large, mechanical performance is strong, density advantages of higher, durable in use.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
