Abstract
The present invention relates to a method for directly producing hole saw tooth rings by using a bimetallic saw band, which belongs to the technical field of mechanical process. The present invention is characterized in that the method comprises three processing steps: step 1, a finished bimetallic saw band is cut in needed length according to the diameter of a hole saw tooth ring; step 2, the cut saw band is pressed to be shaped by a special mould, and a slotted circular tooth ring is formed; step 3, a sectional joint close is welded at last. The special mould is composed of a concave mould with a circular arc groove and a cylindrical convex mould which is correspondingly matched with the concave mould. The present invention has the advantages of simple production method and process. After production probation, hole saw tooth rings can be absolutely and directly shaped and made by finished bimetallic saw bands treated by gear milling and heat treatment, so that equipment investment is largely saved, the production cost of products is lowered, and performance of products on every aspects are the same with the hole saw tooth rings made by the existing traditional processes. Therefore, the present invention overcomes prejudice of general technical personnel that hole saw tooth rings can only be produced by the existing method.
Description
[technical field]
The invention belongs to the Machining Technology field, be meant that specifically a kind of double metal saw belt directly produces the method for hole saw gear ring.
[background technology]
Present manufacturing of hole saw gear ring, the general bimetal saw blade that constitutes without mill teeth and heat treatment, by high-alloy steel and high-speed steel that adopts, through mill teeth, by automatic moulding machine volume type make, welding fabrication, more after heat treatment the hole saw gear ring.This making will have automatic moulding machine and heat treatment two large equipments at least, Equipment for Heating Processing particularly, the metal material that multiple unlike material is arranged in the hole saw gear ring product because of last making moulding, requirement when heat-treating is very high, common homemade Equipment for Heating Processing can't satisfy production requirement, all adopts the import Equipment for Heating Processing at present, and the said equipment gross investment is more than 4,000,000 yuan, cause that investment is big, production cost improves greatly, general manufacturer has to hang back.And above-mentioned Equipment for Heating Processing must be operated by present professional technique engineer very in short supply, has carelessness may cause whole stove gear ring product rejection slightly.And through mill teeth and heat treated finished product saw band, because hardness is very high, adopt mill teeth and heat treated finished product saw band straight forming making hole saw gear ring, quilt professional and technical personnel is in the industry thought not meet the technology convention, also can not be produced the product that meets instructions for use, the rule is and to adopt existing traditional handicraft to manufacture the hole saw gear ring that also not seeing on the publication has similar report at home and abroad.
[summary of the invention]
The object of the invention is exactly in order to solve problems of the prior art, and a kind of technical scheme of directly being manufactured hole saw gear ring method by bimetallic finished product saw band is provided.
Described double metal saw belt is directly produced the method for hole saw gear ring, it is characterized in that comprising following processing step:
1) bimetallic finished product saw band is cut into needed length by the hole saw diameter ring gear.
2) adopt mould compression moulding, make the annulus gear ring that cracks.
3) at last the section joint close is welded.
Described mould is made of the die and the corresponding matched cylindrical male of band arc groove.
Described double metal saw belt is directly produced the method for hole saw gear ring, it is characterized in that described section joint close welding employing argon arc welding.
Described double metal saw belt is directly produced the method for hole saw gear ring, it is characterized in that described compression moulding employing punching press or hydraulic pressure or hand compacting.
Described double metal saw belt is directly produced the method for hole saw gear ring, it is characterized in that described die main body is a rectangular configuration, has an arc groove with the mating surface of punch, and the punch main body is a cylindrical structure.
Described double metal saw belt is directly produced the method for hole saw gear ring, it is characterized in that the arc groove surface of die is shiny surface or ripple struction.
Described double metal saw belt is directly produced the method for hole saw gear ring, and the periphery that it is characterized in that punch is shiny surface or ripple struction.
Aforementioned production method, technology is very simple, on probation through producing, fully can be by mill teeth and heat treated bimetallic finished product saw band straight forming are made the hole saw gear ring, thereby saved equipment investment greatly, reduced production cost of products, and the hole saw gear ring that the every performance of product and existing traditional handicraft are made does not have different.Thereby overcome those skilled in the art and thought the prejudice that to produce the hole saw gear ring with existing method traditionally.
[description of drawings]
Fig. 1 is the perspective view of mould used in the present invention.
[specific embodiment]
Below in conjunction with Figure of description, the invention will be further described, and provide the specific embodiment.
Adopt mill teeth and heat treated bimetallic finished product saw band, by previous process steps processing.Argon arc welding is adopted in described section joint close welding.Punching press or hydraulic pressure or hand compacting are adopted in described compression moulding, and its former is the conventional, well-known technology, is not giving unnecessary details at this.Described particular manufacturing craft as shown in Figure 1, die 1 main body is a rectangular configuration, has an arc groove with the mating surface of punch 2, punch 2 main bodys are cylindrical structure, can be single cylindrical body or bicylindrical body structure.Arc groove internal diameter on the die 1 is slightly larger than the external diameter of the cylinder punch 2 that cooperates with it, and decides according to the hole saw diameter ring gear size of made.The arc groove surface of die 1 can be shiny surface, also can be ripple struction; The periphery of punch 2 can be shiny surface, also can be ripple struction.
