Abstract
Location structure is welded the utility model discloses a kind of hard alloy cutter and steel matrix, the structure include hard alloy cutter and and steel matrix, the handle of a knife of described hard alloy cutter is provided with two parts of positioning shaft part and welding section, after in the location hole of handle of a knife insertion steel matrix, positioning shaft part on hard alloy cutter forms gap and coordinates with the location hole of steel matrix, weld seam is formed between the welding section and the location hole of steel matrix on hard alloy cutter simultaneously, handle of a knife and the steel matrix of hard alloy cutter are welded together by weld seam.The utility model solves the problems, such as positioning and welding simultaneously using the positioning shaft part and welding section on hard alloy cutter handle of a knife in the case of without fixture, it is ensured that hard alloy cutter hub and steel matrix axiality and tripping problems.
Description
Technical field
The utility model is related to a kind of hard alloy cutter to weld location structure with steel matrix, belongs to machining tool skill
Art field.
Background technology
As the cost of the increase of cutter manufacture cost, especially solid carbide is dramatically increased, some are medium and small
Enterprise wishes to obtain the performance with solid carbide to reduce entreprise cost when cutter is selected, and can have height concurrently again
The cutter of the price advantage of fast steel cutter.On the other hand, to coordinate the requirement on machine tool and drilling machine using cutter, Mohs is bored
Handle is a kind of preferable structure type as Knife handle structure.Therefore, how hard alloy cutter effectively to be tied with Morse taper shank
Altogether, and the problem of hard alloy cutter hub and steel matrix axiality and bounce is ensured, as reduction enterprise cutter use cost
Technical problem urgently to be resolved hurrily.
Utility model content
The technical problems to be solved in the utility model：A kind of hard alloy cutter is provided and welds location structure with steel matrix,
To solve in the case of no fixture using HF induction heating apparatus welding hard alloy cutter hub and steel matrix handle of a knife process
In, hard alloy cutter hub and steel matrix axiality and tripping problems.
The technical solution of the utility model：A kind of hard alloy cutter welds location structure with steel matrix, including hard is closed
Golden cutter and and steel matrix, the handle of a knife of described hard alloy cutter is provided with two parts of positioning shaft part and welding section, knife
After in the location hole of handle insertion steel matrix, the positioning shaft part on hard alloy cutter forms gap and matches somebody with somebody with the location hole of steel matrix
Close, while welding section on hard alloy cutter and weld seam is formed between the location hole of steel matrix, the handle of a knife of hard alloy cutter
Welded together by weld seam with steel matrix.
In said structure, described steel matrix is 2# standard Morse taper shanks.
Due to using above-mentioned technical proposal, the utility model has the advantage of：The utility model uses hard alloy cutter
Positioning shaft part and welding section on handle of a knife solve the problems, such as to position and weld simultaneously in the case of without fixture, it is ensured that hard
Alloy cutter hub and steel matrix axiality and tripping problems.Simultaneously as hard alloy bar has well with Morse taper shank location hole
Axiality, hard alloy bar can be saved with minimal reduction hard alloy blank diameter, it is final to realize reducing welding
Cutter manufacture cost.And cutting edge portion of the present utility model is divided into Hardmetal materials, service life higher speed steel knife has
Significantly improve.Therefore, the utility model is particularly suited on machine tool and drilling machine the cutter stepped up by Morse taper shank hole.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Description of reference numerals：1- hard alloy cutters, 2- positioning shaft part, 3- steel matrix, 4- location holes, 5- weld seams, 6- welderings
Connect section.
Specific embodiment
In order that the utility model purpose, technical scheme and advantage are clearer, below in conjunction with the accompanying drawings and embodiment pair
The utility model is described in further detail.
Embodiment of the present utility model：Hard alloy cutter welds structural representation such as Fig. 1 of location structure with steel matrix
It is shown, including hard alloy cutter 1 and with steel matrix 3, described steel matrix 3 is 2# standard Morse taper shanks；Described hard
The handle of a knife of alloy cutter 1 is provided with positioning shaft part 2 and welding section 6 two parts, in the location hole 4 of handle of a knife insertion steel matrix 3 after,
Positioning shaft part 2 on hard alloy cutter 1 forms gap and coordinates with the location hole 4 of steel matrix 3, while on hard alloy cutter 1
Welding section 6 and the location hole 4 of steel matrix 3 between form weld seam 5, the handle of a knife of hard alloy cutter 1 passes through weld seam with steel matrix 3
5 weld together.
During specific implementation, the handle of a knife of hard alloy cutter 1 is processed into 6 two parts of positioning shaft part 2 and welding section first,
The positioning of the positioning shaft part 2 and steel matrix 3 that then in the location hole 4 of handle of a knife insertion steel matrix 3, will make on hard alloy cutter 1
Hole 4 forms gap and coordinates, and its gap width is 0.01mm；Make determining for welding section 6 on hard alloy cutter 1 and steel matrix 3 simultaneously
Position forms weld seam 5 between hole 4, the most backward filling of weld seam 5 cemented carbide powder, and heats weld seam by HF induction heating apparatus
Cemented carbide powder in 5, after cemented carbide powder melts and solidifies, just welds the handle of a knife of hard alloy cutter 1 with steel matrix 3
Be connected together in succession, it is ensured that the handle of a knife of hard alloy cutter 1 be connected with steel matrix 3 after axiality and bounce.
