Abstract
The present invention relates to a production line for manufacturing hollow chopsticks from stainless steel stretched circular pipes. Stretched stainless steel circular pipes with the thickness of 0.3 millimeters are selected for blanking according to the design dimension of chopsticks, and arranged stretched stainless steel circular pipes are conveyed into a rotary forging machine for being forged into conic circular pipes Shaped conic circular pipes are annealed by an industrial furnace for eliminating material stress, and then are pickled for removing oxidized scales to brighten the conic circular pipes. The big end of each conic circular pipe is extruded by a four-wheel extruding machine, so that the big end of each conic circular pipe is deformed into a conic square pipe. Each conic square pipe is corrected by a horizontal punching machine, a circular small end at the lower end of a chopstick is annealed partially, and the circular small end of the chopstick is sealed by a rolling and rotary pressing mode. A vertical punching machine die is used for punching a square cap with rectangular pyramid degree of the chopstick, and then the square cap with rectangular pyramid degree is welded by a resistance welding method, and finally the chopstick is sharpen, polished and engraved with words and patterns. The present invention can fully make use of material properties and is good for fine processing. Chopsticks produced by the production line have light weight, smooth appearance, comfortable use and favorable airtightness, and poems and pictures can be processed on the chopstick bodies.
Description
Technical field
The present invention relates to a kind of production method of chopsticks, be specifically related to a kind of production method with manufacturing hollow chopsticks from stainless steel stretched circular pipe.
Background technology
At present, the solid chopsticks of Korea S's import stainless steel materials drawing are arranged on the domestic market, this chopsticks are heavy, and it is not too convenient to use.Homemade a kind of be that stainless steel materials strikes out integrally welded hollow chopsticks behind the chopsticks body two halves, another kind is the hollow chopsticks that the high-frequency welding stainless pipe is made, these two kinds of explained hereafter chopsticks are subjected to material and process limitation, be unfavorable for fine finishining, the chopsticks outward appearance of producing is not smooth, feel and poor air-tightness, the romantic charm that is difficult to show chopsticks.
Summary of the invention
The objective of the invention is for overcoming disadvantages of background technology, and a kind of material property that makes full use of is provided, be beneficial to accurately machined production method with manufacturing hollow chopsticks from stainless steel stretched circular pipe.The chopsticks that adopt this production method to produce are light, the outward appearance smoothness, and comfortable feel, air-tightness is good, and poem can be drawn processing on the chopsticks body.
To achieve these goals, the technical solution used in the present invention is: a kind of production method of manufacturing hollow chopsticks from stainless steel stretched circular pipe is characterized in that this production method may further comprise the steps:
(1) select the stretching stainless pipe of 0.3 millimeters thick by the blanking of chopsticks design size;
(2) will descend the stretching stainless pipe of honest material to send into the rotation forging press and forge into the tapering pipe;
(3) shaping tapering pipe is eliminated material stress with industrial electric furnace annealing, the pickling descale makes tapering pipe light;
(4) with the big end of four-wheel extruder extruding tapering pipe, make the tapering pipe be deformed into the tapering square tube, adopt the smart positive tapering square tube of horizontal punching machine, chopsticks are one-step forming just;
(5) with the chopsticks lower end circle microcephaly differential annealing of first one-step forming in the step (4), rolling spinning seals chopsticks circle microcephaly;
(6) stamp out rectangular pyramid degree square toes cap with vertical punching machine mold, rectangular pyramid degree square toes cap punching press is good with electric resistance welding is welded on the tapering square tube major part of every chopsticks in the step (5);
(7) every chopsticks in the step (6) are carried out sanding and polishing, on chopsticks, engrave calligraphy and painting with caustic solution or laser engraving machine at last, the hollow chopsticks packing warehouse-in of complete moulding.
The present invention compared with prior art has the following advantages: the present invention can make full use of material property, is beneficial to fine finishining, and the chopsticks that adopt this production method to produce are light, the outward appearance smoothness, and comfortable feel, air-tightness is good, and poem can be drawn processing on the chopsticks body.
The specific embodiment
Be that 96 chopsticks are that example describes production method of the present invention in detail to produce 48 pairs of chopsticks below:
(1) selecting three long 8 meters, calibers is that Φ 8, wall thickness are that 0.3 millimeter stretching stainless pipe carries out blanking by the length of 0.25 meter of every chopsticks with cutting machine;
(2) 96 length will descending are that 0.25 meter stretching stainless pipe is sent into the rotation forging press and forged into the tapering pipe, and tapering pipe major part caliber is Φ 8, and tapering pipe microcephaly caliber is Φ 3;
(3) the shaping tapering pipe in the step (2) is eliminated material stress with industrial electric furnace annealing, the pickling descale makes tapering pipe light;
(4) use four-wheel extruder extruding tapering pipe major part, make tapering pipe major part be deformed into the tapering square tube, tapering square tube major part is of a size of 6.5 millimeters * 6.5 millimeters, adopts the smart positive tapering square tube of horizontal punching machine, every first one-step forming of chopsticks;
(5) with first every chopsticks lower end caliber of one-step forming be Φ 3 tapering pipe microcephaly differential annealing, rolling spinning envelope chopsticks circle microcephaly in the step (4);
(6) stamp out 96 rectangular pyramid degree square toes caps with vertical punching machine mold, each square toes cap is of a size of 6.5 millimeters * 6.5 millimeters, is welded on every chopsticks tapering square tube major part in the step (5) with the electric resistance welding rectangular pyramid degree square toes cap that punching press is good;
(7) every chopsticks in the step (6) are carried out sanding and polishing, on chopsticks, engrave calligraphy and painting with caustic solution or laser engraving machine at last, 96 hollow chopsticks packing warehouse-ins of complete moulding.
