A kind of no-welding-seam lightweight water heater liner and manufacture method thereof, described inner bag is a staving, including drum head, ladle body and the end socket of band opening；Inner bag is integral type structure, and drum head wall thickness is uniform thickness, and ladle body wall thickness thickness is less than drum head wall thickness, and end socket wall thickness thickness is less than or equal to ladle body wall thickness thickness.Its manufacture method includes: 1) circular plate side central authorities carry out strong general rotation to circular plate against the core of circular arc drum head shape, circular plate opposite side spinning roller, obtain drum head and ladle body；2) using holder ladle body, with spinning roller, ladle body opening is carried out mould pressing, reducing, spinning roller shapes the circular arc that track is band opening, finally gives the end socket of band opening.Weld seam is become no-welding-seam from traditional three by the present invention, reduces water heater water leakage ratio, realizes product lightweight simultaneously, improves product quality and reduces cost, leaking and production cost problem in order to solve water heater.
Description
Technical field
The present invention relates to sheet forming technology, particularly to the product of a kind of no-welding-seam lightweight water heater liner
Product and manufacture method.
Background technology
Water heater liner uses conventional ones welding procedure to manufacture, and water leakage ratio is higher, and at middle cylinder
Weld seam is required for artificial repair welding, wasting manpower and material resources with the junction of end socket boxing.
Include integrally revolving as China Patent Publication No. CN202182565U discloses a kind of water heater liner
The middle bucket of pressure stretch forming and right end socket, the left end socket of the other end is connected by boxing with bucket in inner bag.
China Patent Publication No. CN203100173U discloses a kind of water heater liner and includes by once drawing
The upper and lower bucket of inner bag of plutonic type, upper and lower bucket is attached through welding.
Above patent still suffers from weld seam, however it remains risk of leaking, and is not directed to the lightweight of product
Design, still for waiting wall thickness inner bag.
Summary of the invention
It is an object of the invention to provide a kind of no-welding-seam lightweight water heater liner and manufacture method, will weldering
Stitch and become no-welding-seam from traditional three, reduce water heater water leakage ratio, realize product lightweight simultaneously,
Improve product quality and reduce cost, leaking and production cost problem in order to solve water heater.
For reaching above-mentioned purpose, the technical scheme is that
A kind of no-welding-seam lightweight water heater liner, it is a staving, including drum head, ladle body and band opening
End socket；It is characterized in that, described water heater liner is integral type structure, and drum head wall thickness is uniform thickness,
Ladle body wall thickness thickness is less than drum head wall thickness, and end socket wall thickness thickness is less than or equal to ladle body wall thickness thickness.
Preferably, the wall thickness of described water heater liner drum head is 1.5～3.0mm, ladle body and end socket wall thickness
It is 0.9～2.0mm.
The manufacture method of no-welding-seam lightweight water heater liner of the present invention, comprising:
1) circular plate side central authorities use against the core of circular arc drum head shape, circular plate opposite side
Spinning roller carries out strong general rotation composite spinning to circular plate, obtains drum head and ladle body；
2) use holder ladle body, with spinning roller, ladle body opening is carried out mould pressing, reducing, spinning roller
Shape the circular arc that track is band opening, finally give the end socket of band opening；Finally obtain integrated welding seam-free
Water heater liner.
Further, outside described circular plate, central authorities set compressing rod.
The present invention proposes equal strength lightweight water heater liner, it is ensured that the drum head (blind end that stress is maximum
End socket) it is uniform thickness, the end socket of ladle body and band opening carries out thinning, inner bag stress safety, by controlling
The thickness distribution of product obtains equal strength product, and then realizes lightweight.
Compared to existing technology, present invention have the advantage that
1. by the present invention in that by lathe turner's skill strong, general, strong by the thickness distribution acquisition of control product etc.
Degree product, and then realize lightweight, save material materials, reduce cost；
2. the present invention is directly by flat blank mould pressing product, removes boxing step, reduces risk of leaking；
Manufacture method advantages of simple the most provided by the present invention, direct investment spinning machine, one step forming,
It is not required to change moulds of industrial equipment, wherein omits punching press and welding procedure, improve production efficiency, reduce mould
Production cost.

Fig. 2 is the structural representation of the present invention not uniform thickness seamless inner container for water heater.
Fig. 3 is the schematic diagram of manufacture method of the present invention.
Fig. 4 is the schematic diagram of manufacture method embodiment of the present invention.
Detailed description of the invention
Seeing Fig. 2, a kind of no-welding-seam lightweight water heater liner 1 of the present invention, it is a staving, bag
Include the end socket 13 of drum head 11, ladle body 12 and band opening；Described water heater liner is integral type structure,
Drum head 11 wall thickness is uniform thickness, and ladle body 12 wall thickness thickness is less than drum head 11 wall thickness, and end socket 13 wall thickness is thick
Degree is less than or equal to ladle body 2 wall thickness thickness.
Preferably, the wall thickness of described water heater liner drum head 11 is 1.5～3.0mm, ladle body 12 and envelope
13 wall thickness are 0.9～2.0mm.
The present invention proposes equal strength lightweight water heater liner, as in figure 2 it is shown, wherein lightweight is thinning
Region is water heater straight wall section and opening part end socket region.Guarantee blind end end socket--the bucket that stress is maximum
The end 11 is uniform thickness, and the end socket 13 of ladle body 12 and other end opening carries out thinning, inner bag stress safety,
Obtain equal strength product by controlling the thickness distribution of product, and then realize lightweight.
The manufacture method of no-welding-seam lightweight water heater liner of the present invention, comprising:
1) circular plate 10 side central authorities are against the core 20 of circular arc drum head shape, circular plate 10
