Abstract
The utility model relates to a structural improvement of chopsticks. The utility model provides a pair of metal chopsticks of hollow structure. The main body of each of the chopsticks is a sealed elongated metal casing, which is manufactured by the processes of metal sheets of opening, cutting, molding, welding and burnishing.
Description
The utility model relates to the improvement of the structure of chopsticks.
Normally used meal chopsticks are to utilize timber or plastics manufacturing to form, and its structure all adopts solid construction.These chopsticks have a lot of shortcomings, for example, make the solid construction chopsticks owing to use more raw material, have in fact caused raw-material waste, and the chopsticks that utilize timber or plastics to make, often easy deformation.Consider that from hygienic requirements this chopsticks also are less-than-ideal.
The purpose of this utility model provides a kind of Metal chopsticks of hollow-core construction.
Below in conjunction with accompanying drawing chopsticks of the present utility model and manufacture method thereof are described.
Fig. 1 is the outward appearance and the structure chart of the elongated hollow chopsticks of sealing, wherein A-A is the cross-sectional structure figure of hollow chopsticks butt end, its cross section is the square frame shape, B-B is the cross-sectional structure figure of the thin end of hollow chopsticks, its cross section is the garden ring-type, because chopsticks are hollow-core construction, therefore the material that is used to make chopsticks must have enough rigidity, to prevent the distortion of chopsticks, for example select for use stainless steel material to make chopsticks, can guarantee the rigidity of chopsticks, also meet hygienic requirements simultaneously.Making hollow-core construction Metal chopsticks of the present utility model has multiple technique manufacturing method, selects a kind of typical technique manufacturing method to be described below.
At first the material of making the hollow-core construction Metal chopsticks is selected, preferable material is the stainless steel sheet material of 0.4-0.6 millimeter thickness; Through opening material and shearing and make elongated as shown in Figure 2 chopsticks embryo sheet, this embryo sheet end parts broad that keeps left, be used to make the chopsticks butt end, the end parts of keeping right is narrower, is used to make chopsticks and carefully holds, and the ratio of the length of butt end and thin end is arbitrarily, preferred ratio is 1:1, with chopsticks embryo sheet punching out one-tenth " U type slotted vane " as shown in Figure 3, use special-purpose roll squeezer as shown in Figure 4 that " U type slotted vane " is pressed, to form the tubular chopsticks embryo of hollow-core construction as shown in Figure 5.In this roll squeezer, shown in Fig. 4 A-A, the middle body of two roll shafts respectively has " concave groove " and " semi-round groove " of symmetry, " concave groove " is used for roll-in chopsticks butt end, make chopsticks butt end cross section become the square frame shape, " half slot " is used for the roll-in chopsticks and carefully holds, make the thin end section of chopsticks become circular.Before roll-in, be preferably in axle in the metal that is bumped into the chopsticks shape in " U type slotted vane "; Behind the roll-forming, extract axle in the metal out, crack longitudinally to tubular chopsticks embryo welds then, and the chopsticks end diaphragm seal of inciting somebody to action as shown in Figure 6 is welded on the chopsticks end, shell with the sealing that forms hollow chopsticks, positive square diaphragm seal is used to seal the chopsticks butt end among Fig. 6, and garden type diaphragm seal is used to seal chopsticks and carefully holds.In above-mentioned welding, typical welding is to use the argon arc welding machine of 220-380 volt, 10-100 peace to weld, it is to be fixed on a certain certain location that the weldering of argon arc welding machine is chewed in welding process, make the crack of required welding in welding process, can chew operation, thereby finish welding crack with respect to weldering.For example when vertical crack of welding chopsticks, chopsticks are clamped on the workbench of making linear running, and the crack of chopsticks can be chewed in workbench linear running process over against weldering, for another example when the diaphragm seal of two ends of welding chopsticks, the chopsticks end is clamped on the workbench that rotates, makes that the crack between chopsticks end cross-sectional and the diaphragm seal can be chewed over against weldering in the workbench rotation process.When vertical crack of welding chopsticks, preferred welding current is the 25-50 peace, and speed of welding is the 300-800 centimeters/minute, the welding throughput be the 2-5 liter/minute; When the end diaphragm seal of welding chopsticks, preferred welding current is the 10-20 peace, and the welding rotating speed is 15 rev/mins, and be 8-20 second weld interval, the welding throughput be the 2-5 liter/minute; After welding is finished,, promptly can be made into hollow-core construction Metal chopsticks of the present utility model through roll extrusion straightening and corase grind, middle mill, fine grinding and polishing.
Hollow-core construction Metal chopsticks of the present utility model has been saved the raw material of making chopsticks.As select for use stainless steel to make the chopsticks raw material, made chopsticks can use indeformable for a long time, and not only attractive in appearance but also health.
Claims (2)
1, a kind of meal chopsticks is characterized in that, said chopsticks are hollow-core constructions, and its main body is a sealing, elongated metal shell, this shell be by metal sheet through opening material, shearing, moulding and welding, polishing forms.
2,, it is characterized in that the metal shell of said chopsticks is preferably formed by the manufacturing of stainless steel sheet material according to the described chopsticks of claim 1.
