Abstract
A forward-backward drawing technology for integral manufacturing the vacuum insulating cup includes such steps as blanking, forward drawing, backward drawing, welding, vacuumizing and sealing. Its advantages are no-seam on top edge, simple technology, and low cost.
Description
Technical field
The present invention relates to one-body molded vacuum cup of a kind of positive and negative drawing and production technology.Be applicable to the stainless-steel vacuum thermos cup.
Background technology
The vacuum cup of Xiao Shouing in the market, be with the respectively stretched internal layer 1 of Thin Stainless Steel steel plate and outer 2 ', be welded into one with argon arc welding again, rim of a cup outside form weld seam 4 ', by the air from the vacuum orifice 3 ' interlayer of finding time that is located at outer bottom, make interlayer keep vacuum state, to reach the purpose of insulation, its structure as shown in Figure 1.But existing this vacuum cup exists following defective in structure and technology: 1) structurally will distinguish stretched internal layer and skin, by being welded into integral body, form interlayer then.Whole process will be with several pairs of moulds, and cost is higher relatively; 2) be used to the to stretch material of cup is very thin, and generally below 0.6mm, it is bigger therefore to weld difficulty, and the position of weld seam will touch when people drink water in rim of a cup portion, so just require a weld grinding smooth smooth.One circle weld seam should polish smooth smooth, and the profile unanimity is attended to one thing and lose sight of another through regular meeting in the operation again, unless you give your whole attention to it, very easily grinds pore, will leak gas when vacuumizing, and causes waste product.3) because inside and outside layer must be in the welding of rim of a cup portion, so the radian of rim of a cup can not be selected arbitrarily.
Summary of the invention
The technical problem to be solved in the present invention is: one-body molded vacuum cup of a kind of positive and negative drawing and production technology are provided, and this thermos cup technology is simple, cost is low; Rim of a cup portion does not have seam, and is smooth smooth, need not polishing, and percent defective is low; The radian of rim of a cup can design arbitrarily according to market and user's hobby, and the choice is big.
The technical solution adopted in the present invention is: the one-body molded vacuum cup of positive and negative drawing, it is characterized in that cup has internal layer and skin that smooth transition fuses, and vacuumize in the inside and outside interlayer, outer bottom is provided with vacuum orifice.
Being shaped as of described cup is cylindrical, also can be up big and down small truncated cone-shaped, ellipse, square, flat, semicircle.
The production technology of the one-body molded vacuum cup of positive and negative drawing of the present invention may further comprise the steps:
1) blanking calculates good material according to shape, the size process of cup;
2) just stretch, select the skin of particular manufacturing craft stretching cup on stretching-machine;
3) reverse-drawing, the opposite direction that just stretching in the particular manufacturing craft upper edge is finished reverse-drawing, forms the internal layer of cup;
4) weld bond at bottom of cup welding vacuum orifice, is used for interlayer and vacuumizes;
5) vacuumize, take out laminated vacuum in accordance with regulations with the vacuum machine;
6) seal, the openning sealing that vacuumizes.
The invention has the beneficial effects as follows: the cup of thermos cup adopts same material skin just to stretch, the internal layer reverse-drawing is to form interlayer, and is outer to the internal layer smooth transition, removed the seam and the welding sequence on rim of a cup top, avoided the gas leak phenomenon that causes because of polishing welding seams, percent defective reduces greatly; The radian size of rim of a cup, shape can design arbitrarily according to market situation and consumer's hobby, the rim of a cup smooth and beautiful appearance, and the choice is big; The more inside and outside layer of used mould stretches respectively and will lack.
Description of drawings
Fig. 1 is the partial sectional view of prior art of the present invention.
Fig. 2 is a half sectional view of the present invention.
The specific embodiment
As shown in Figure 2, the truncated cone-shaped that present embodiment is big up and small down, internal layer 1 and outer 2 fuses, in rim of a cup place smooth transition, opposing parallel between internal layer and the skin forms crack in order to vacuumize, and has vacuum orifice 3 in outer bottom center, after vacuumizing with the vacuum machine, be about to this openning and seal up.
Shape of the present invention is not limited only to above-mentioned shape, can be drawn into cylindrical, oval, square, flat, semicircle or the like shape by special mould.
On cup handle can be housed, also can not adorn handle, can be single handle, also can be two handles.
Height as need stretching reverse frustoconic cup is about 100mm, and diameter is about 50mm, and its processing technology is as follows:
1) blanking, adopting thickness is the Thin Stainless Steel steel plate of 0.3～0.8mm, the circle material that following diameter is 100～300mm;
2) just stretch, select the skin 2 of particular manufacturing craft stretching cup on stretching-machine, tensile elongation 200-280mm, particular manufacturing craft generally will use and overpay, and the quantity of mould is taken all factors into consideration according to the shape of cup and die sinking person's technical merit and cost factor;
3) reverse-drawing, the opposite direction that just stretching in the particular manufacturing craft upper edge is finished reverse-drawing, forms the internal layer 1 of cup, tensile elongation 70-130mm, inside and outside two-layer between opposing parallel form crack;
4) weld bond, at bottom of cup welding vacuum orifice 3, the about 3mm of diameter is used for interlayer and vacuumizes;
5) vacuumize, take out laminated vacuum in accordance with regulations with the vacuum machine;
6) seal, the openning sealing that vacuumizes.The circular metal plate that sealing means can use the diameter with vacuum orifice to match is earlier blocked openning, sheet metal and cup back welding is lived again.
