Description
Technical field
The present invention relates to metal vacuum container liner manufacture field more particularly to a kind of metal vacuum container integral types
The manufacturing method of light weight liner.
Background technology
Existing metal vacuum container such as stainless steel（Titanium）Vacuum cup, Dewar bottle etc. generally comprise three-decker, i.e.,
Liner, vacuum layer, outer courage, and the liner of existing metal vacuum container be usually the welding pipe that is penetrated through with both ends during fabrication into
Liner semi-finished product are formed after a series of processing of row, then liner is spliced to form by welding metal bottom in liner at the bottom.
Although this liner can play the role of contain liquid, vacuum layer can be formed between outer courage, its
It needs to be reprocessed into liner semi-finished product, and in addition welding upper inner-liner bottom at welding pipe from sheet fabrication in process,
Manufacturing process is relatively complicated, and has multi-pass welding piece, affects the aesthetics of product, and also resulting in product should not clean, and
And weld seam also has vacuum failure risk.In addition, existing liner general thickness is thicker, so as to cause its heavier-weight, and cause
The heavier-weight of finally obtained metal vacuum container damages the product usage experience of user.
Invention content
The present invention is cumbersome for liner manufacturing process existing in the prior art, and molding liner has multi-pass welding piece,
The aesthetics of product is affected, and liner thickness is thicker, it is heavier equal scarce so as to cause finally obtained metal vacuum container weight
It falls into, provides a kind of manufacturing method of new metal vacuum container integral type light weight liner.
In order to solve the above-mentioned technical problem, the invention is realized by the following technical scheme：
A kind of metal vacuum container manufacturing method of integral type light weight liner, includes the following steps：
（1）A round plate body is taken, punching press is carried out to the round plate body, so that circular slab body is formed the uniform liner of wall thickness former
Type simultaneously forms outside flange in the upper end of the liner prototype；
（2）By the thin machine of rotation to the middle section thinning processing of progress spinning of the liner prototype to form thinner wall section,
In liner prototype upper thick wall portion, lower thick wall portion are being formed relative to the part other than thinner wall section；
（3）By roller press to being carried out at beading close to the junction of upper thick wall portion and thinner wall section on the upper thick wall portion
Reason forms reinforcing rib；
（4）Scarfing is carried out to the upper end of liner prototype to handle to remove the flange；
（5）Necking processing is carried out to the upper thick wall portion of liner prototype by empty contracting machine, to form contracting on upper thick wall portion
Oral area simultaneously forms redundancy portion in the top of choke, and the choke includes the first choke, the second necking successively from top to bottom
Portion, third choke, the first choke, the second choke, the contracting of third choke are different；
（6）The upper end of necking treated upper thick wall portion is carried out cutting head and is handled to remove the redundancy portion, obtains one
Body formula light weight liner.
It is to realize one by the way that round plate body is carried out globality punching press by integral type light weight liner made from above step
Body formula structure, to which effective solution needs to carry out multi-pass welding process in the prior art and can form asking for multiple tracks piece
Topic, and the flange of the upper end of liner prototype can ensure that round plate body can be molded in punching press by normal ram, while also protecting
Demonstrate,prove intensity of liner prototype during subsequent handling.And spinning is carried out to the middle section of the liner prototype by revolving thin machine
