Abstract
The method for manufacturing dual-layer stainless steel hand cup (heat-insulating cup) includes such technological steps as drawing circular stainless steel plate several times to form an opening cylindrical inner layer, drawing stainless steel plate several times to form outer layer, making cup edge by punching the outer layer, and argon arc welding the cup opening and bottom. Its advantages are no seam on inner wall, better seal and insulating performance, and long service life.
Description
The present invention relates to a kind of full stretching double-layer stainless steel palm cup manufacture method and products thereof.Belong to the drawing metallic plate and curve tube of material technical field and technical field of living goods.
The manufacture method that the stainless steel of selling is in the market protected cup all is that pipe and outer tube are reprocessed into thermos cup in being welded into corrosion resistant plate.Though the outer tube weld seam is modified through processing, outward appearance always can not be satisfactory; Interior pipe weld material can not be identical with sheet material, can contain various beverages such as tea in the use, can influence the heat-insulating property and the service life of thermos cup in the course of time.
The objective of the invention is to weak point at existing like product, provide a kind of full stretching double-layer stainless steel palm cup manufacture method and products thereof, by the product of method manufacturing of the present invention, not only outward appearance novel and beautiful, and the persistence of raising heat-insulating property, increase the service life.
The objective of the invention is to be achieved through the following technical solutions.
Full stretching double-layer stainless steel palm cup manufacture method, step is as follows:
A) the cylindrical shape internal layer (1) that the corrosion resistant plate circular blank is repeatedly stretched make an end opening,
B) will repeatedly stretch than the big corrosion resistant plate of internal layer blank diameter regulation and make the bottom and slightly become bell-mouthed cylindrical shape skin (2), again with skin (2) other end usefulness anchor clamps fixed punch cup mouth,
C) outer (2), internal layer (1) and plectane (3) are with the argon arc welding rim of a cup and the cup end.
After outer (2) stretch, in the bottom roll extrusion circular groove and the gradient of dwindling to the bottom.After internal layer (1) stretches, strike out internal thread (10) with special anchor clamps and to projecting inward fold (11) at openend.After outer (2) stretch, also its middle part can be rolled into the recess of being convenient to hold cup.Cup is put into totally enclosed type become in the vacuum (-tight) housing and vacuumize, heat again after vacuumizing silver-colored ashbury metal is melted sealing by prefabricated hole, plectane (3) center.Plectane (3) is placed with carbon granules before welding.The double-layer stainless steel palm cup of making is formed cup by interior cover (1), overcoat (2), plectane (3), also is provided with base (8) and separable lid (7).(2) middle part depression is provided with rubber ring in the outer ring.
The present invention's double-layer stainless steel palm cup manufacture method that stretches entirely, characteristics are that the stainless steel that repeatedly stretches is constant, and the cup inwall is seamless, improves sealing property, and good heat insulating has prolonged service life, and the also seamless profile of cup outer wall is handsome in appearance.
Below in conjunction with accompanying drawing embodiments of the invention are described in further detail.
Fig. 1 is the generalized section of an embodiment of double-layer stainless steel palm cup of the present invention;
Fig. 2 is Fig. 1 embodiment double-layer stainless steel palm cup internal layer drawing step schematic diagram of the present invention;
Fig. 3 is the outer drawing step schematic diagram of Fig. 1 embodiment double-layer stainless steel palm cup of the present invention;
Fig. 4 is the profile of another embodiment of double-layer stainless steel palm cup of the present invention;
Fig. 5 is the double-layer stainless steel palm cup of the with cover and base of the present invention.
Fig. 1 is a double-layer stainless steel palm cup embodiment generalized section of the present invention.Cup mainly divides inside and outside two-layer formation, and internal layer 1 is to make the cylinder of an end opening by monoblock corrosion resistant plate circular blank through repeatedly stretching.Outer 2 also is the monoblock corrosion resistant plate bigger than internal layer blank diameter to be made the bottom through repeatedly stretching slightly become bell-mouthed cylinder.Internal layer 1 welds with outer 2 upper end edge circumference, and outer 2 lower ends and stainless steel plectane 3 weld.
Fig. 2 is Fig. 1 embodiment double-layer stainless steel palm cup internal layer drawing step schematic diagram of the present invention.With circular corrosion resistant plate do blank for example diameter be 195 millimeters as Fig. 2 a, s' 125 millimeters disk through the back that for the first time stretches as Fig. 2 b formation base diameter, it through back as Fig. 2 c formation base diameter that for the second time stretches 100 millimeters higher disk on every side, as the cylinder of the upper end open of Fig. 2 d, 2e, 2f, base diameter is respectively 80,68,54 millimeters after stretching for three, four, five times.According to the different size of double-layer stainless steel palm cup, blank diameter can be 200 millimeters, 230 millimeters ... Deng series.
Fig. 3 is the outer drawing step of a Fig. 1 embodiment double-layer stainless steel palm cup of the present invention schematic diagram.Circular corrosion resistant plate blank diameter is 225 millimeters, 95 millimeters, 75 millimeters, 65 millimeters and forms cylinders such as Fig. 3 b, c, d, e, f, stretches for the 6th time to form horn mouth such as Fig. 3 g that gradient is 5 degree, and the 7th time the back other end that stretches forms undergauge such as Fig. 3 h.
The drawing numbers of internal layer 1 and skin 2 according to the cup different size, can increase and decrease by technological requirement among Fig. 2 Fig. 3, mainly satisfies not cracking, and does not produce the requirement that material changes.
Fig. 4 is the profile of another embodiment of double-layer stainless steel palm cup of the present invention.Do not exist together with Fig. 1, internal layer 1 openend, also can be made into other and covers the shape that matches so that cooperate with lid with rolling depression method system internal thread (13) with to projecting inward fold (11).Outer 2 middle parts are rolled into the depression of being convenient to hold cup; Outer 2 bottoms are rolled into circular groove and to the gradient that the bottom dwindles, are convenient to mounting seat.Plectane 3 centers are provided with the hole, so that be evacuated between ectonexine, use silver-colored ashbury metal (4) sealing again, and carbon granules (5) is laid in plectane 3 inside.
Fig. 5 is that the cup of Fig. 4 is with cover 7, base 8 and rubber ring 9.
