Abstract
The invention discloses a pair of tailor scissors and a manufacturing method thereof. The structure of the tailor scissors is characterized in that: two mutually corresponding fine-casting cutter bodies are assembled by screw holes arranged at the middle parts of the cutter bodies, and then matched with a thread assembly; blades are arranged on the cutting edge positions of the fine-casting cutter bodies; the manufacturing process comprises the following steps: finely die-casting a whole scissor, cropping cutting edge steel, welding the cutter bodies with the edge steel, heat treatment, grinding inner cutting edges, finely grinding small outer cutting edges, plastic dipping, and assembling. Compared with the prior art, the tailor scissors of the invention has the following beneficial effects: the integral forming technique of a handle and an outer large bevel edge is adopted to the scissors, which reduces the loss of a disc and greatly shortens production period and lowers production cost; the head of the scissor is made from two-layer composite material; a copper plate is clamped between the two layers of the composite material; after high-temperature welding is finished, the blade part is shaped like a golden silk thread; the blade is made from composite-layer tool steel, therefore, the cutting edges are not easily collapsed or rolled up; the scissors are sharp and durable with strengthened fatigue resistance; the cutting edge is not limited by welding technique, therefore, various special steel material can be replaced at will.
Description
Technical field:
The present invention relates to a kind of sewing scissors and preparation method thereof, specifically a kind of simplifying optimized manufacturing procedure, improved production efficiency, sewing scissors of compact overall structure unanimity and preparation method thereof.
Background technology:
In the prior art, the production method of dressmaker generally is divided into three kinds, be respectively embedding forging do manual work skill, accurate casting molding process, explosive composite material technology, wherein the embedding forging skill of doing manual work: casting is cut handle → matrix blanking → matrix and the forging of shear steel point and is beaten → cut the little collar extension of mouth in handle and the matrix butt welding → mill slag → punching → heat treatment → mill collar extension → fluffing mouth → fine grinding → finish grind → spray paint → assemble.Wherein accurate casting molding process: the little collar extension of smart casting → punching → heat treatment → mill collar extension → fluffing mouth → finish grind → spray paint → assemble.Explosive composite material technology wherein: the little collar extension of handle → matrix blanking → cut handle and matrix butt welding → mill slag → punching → heat treatment → mill collar extension → fluffing mouth → finish grind → spray paint → assemble is cut in casting.All there is defective in these three kinds of preparation methods on operation, embedding forging manual labour is planted, the explosive composite material technique process is loaded down with trivial details, waste material, production efficiency is low, and product percent of pass is low, other three kinds of preparation methods have mill collar extension operation and painting process, this procedure of mill collar extension is the most complicated of workload maximum, and the resulting product that sprays paint, outward appearance is coarse, the feel discomfort, yield rate is low.
Summary of the invention
Technical problem to be solved of the present invention is at the prior art weak point, has solved numerous and diverse in the past manufacturing procedure, has saved material, has improved production efficiency.The product size of producing is accurately consistent, the standardization level height, and the qualification rate height provides a kind of optimization of simplifying, sewing scissors of compact overall structure unanimity and preparation method thereof.
The present invention solves the technical scheme that its first technical problem adopts: a kind of sewing scissors, its structure is to cooperate the screw sub-assembly to assemble again by the screw that two smart casting cutter hubs of mutual correspondence are offered by the middle part, at the cutting edge position of essence casting cutter hub the blade sheet is installed.
The present invention solves the technical scheme that its another technical problem adopts: a kind of sewing scissors manufacturing process steps is: whole the little collar extension of cutter hub microdiecast → cutting edge steel blanking → cutter hub and cutting edge steel welding → heat treatment → mill internal orifice → finish grind → soak and mould → assemble.
Wherein whole the cutter hub microdiecast: as to be with blade, handle, circular hole, square hole, outer hypotenuse and whole the once complete die casting of cutter hub is formed with high microdiecast technology.
Cutter hub wherein and cutting edge welding procedure: be that cutter hub and blade steel disc therebetween one deck scale copper are located earlier, with high temperature furnace both improved and accurately weld then.
Wherein soak and mould technology: be that handle is partly moulded the plastic outer layer that technology applies one deck smooth and beautiful appearance and comfortable feel with novel soaking.
Compare with original technology with a kind of sewing scissors of the present invention and preparation method thereof, have following beneficial effect:
1, scissor body adopts handle of a knife, the one-body molded technology of the big hypotenuse circle square hole in the outside, saved welding, the polishing of dashing round square hole handle and cutter head in the past, grind numerous and diverse operations such as the big hypotenuse in the outside, and product appearance has obtained better assurance, rectangular 90 degree of big hypotenuse root, the cutting non-uniform phenomenon that occurs in the attrition process, good looking appearance have also been avoided.
2, reduce the loss of emery wheel, greatly reduced production cycle and cost.
3, scissors bit adopts two-layer composite to manufacture, and folder is with copper coin in the multiple layer in both sides, and the good rear knife edge of high-temperature soldering portion is golden yellow silk thread, and blade uses composite bed tool steel to be difficult for collapsing turned mouthful.
4, sharp durable antifatigue degree increases, and cutting edge is not limited by welding procedure, can arbitrarily change various special rolling-mill sections.
5, use novel soaking and mould the product comfortable feel that technology generations tubing flow displacement lacquer is produced, use unconsciously ice-cold special winter, and exquisite appearance is good-looking, and has avoided the substandard products that in the past caused because of handle is coarse, thereby has improved yield rate.
Description of drawings
Accompanying drawing 1 is a kind of explosive decomposition figure of sewing scissors;
Accompanying drawing 2 is the structural representation after a kind of sewing scissors assembling.
The specific embodiment
Next explain below with reference to Figure of description a kind of sewing scissors of the present invention and preparation method thereof being done.
A kind of sewing scissors of the present invention, its structure are to cooperate the screw sub-assembly to assemble again by the screw that two smart casting cutter hubs 1 of mutual correspondence are offered by the middle part, at the cutting edge position of essence casting cutter hub 1 blade sheet 2 are installed.
Parts are dynamically connected till screw that described smart casting cutter hub 1 middle part is offered and the screw sub-assembly that cooperatively interacts, wherein offer round square hole 5 on the smart casting cutter hub, be that cross section one half thickness is that second half thickness of circular hole is the screw of square hole, described another smart casting cutter hub is offered circular hole 4 and get final product, with the designed structure of the screw 6 in the screw sub-assembly that circle square hole 5 matches just in time with justify square hole 5 and match.
