CN1850434A - Production line for manufacturing hollow chopsticks from stainless steel stretched circular pipe - Google Patents

Abstract

The invention is about the production line of the hollow chopsticks by drawing stainless steel round pipe. The pipe with 0.33mm of thickness is transferred into a spin-forging machine to form the taper round pipe which is annealed to remove the material stress by industrial electrical furnace. The pipe is washed by acid to remove oxide skin and to become bright. The big head of the pipe is pressed by the four-wheel extruder to become the taper square pipe and refined by the horizontal punching machine. The small round head is annealed partially and sealed by rolling spinning. The tetraquetrous taper square cap is punched by a vertical punching module and welded by the resistance welding. At last the chopsticks are polished and carved with calligraphy and painting.

Description

The production line of manufacturing hollow chopsticks from stainless steel stretched circular pipe

Technical field

The present invention relates to a kind of production line of chopsticks, be specifically related to a kind of production line 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 line with manufacturing hollow chopsticks from stainless steel stretched circular pipe.The chopsticks that adopt this production line 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 line of manufacturing hollow chopsticks from stainless steel stretched circular pipe is characterized in that this production line 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 line 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 line of the present invention in detail to produce 48 pairs of chopsticks below:

(1) selecting three long 8 meters, calibers is that Ф 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 Ф 8, and tapering pipe microcephaly caliber is Ф 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 Ф 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.

Claims (1)

1, a kind of production line of manufacturing hollow chopsticks from stainless steel stretched circular pipe is characterized in that this production line 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 four-wheel extruder extruding tapering pipe major part, make tapering pipe major part 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);
