Abstract
The invention discloses an inner end cover of an inner container of a water heater. A platform structure is arranged at the joint of the inner end cover and an inner bucket. A bevel connection structure is arranged at the tail end of the platform structure and is inclined in the center line direction of the inner end cover, and the gradient of the bevel connection structure ranges from 150 degrees to 175 degrees. The invention further discloses a girth welding method of the inner end cover and the inner bucket. The platform structure and the bevel connection structure are arranged on the inner end cover, and therefore the inner end cover can be conveniently inserted into the inner bucket along the platform structure, and the structure is stable. Compared with traditional cushion plate adding butt welding, according to the girth welding method, a cushion plate material, a machining procedure and a cushion plate and inner bucket welding procedure are omitted, and production cost is reduced; and the quality of a weld joint is guaranteed through the platform structure of the inner end cover and a filler wire welding method. The inner end cover and the girth welding method have the beneficial effects of facilitating butt joint, saving cost and being high in weld joint quality.
Description
Technical field
The present invention relates to a kind of water heater liner inner end cap and the boxing method with interior bucket, belong to the processing technique field of domestic solar water heater's product inner bag.
Background technology
Radiator leak problem in domestic solar water heater's industry annoyings each enterprise always, and radiator leak is owing to inner water tank girth welding intensity deficiency causes mostly.Due to the problem of assembly difficulty, at present, bucket and inner end cap are welded with two kinds of methods: overlap welding and add backing plate butt welding.Overlap welding weld strength is low, and press-bearing water tank needs to bear the pressure of more than 0.6MPA, and weld strength is not enough to support so big pressure；And add backing plate butt welding owing to adding backing plate in welding line structure, and causing and production process adds backing plate manufacturing procedure, and need before girth welding to be welded to by pad on interior bucket, production efficiency is low, and cost is high；In addition typically directly carrying out girth welding with inner end cap after bucket straight seam welding in inner bag production process, owing to interior bucket straight bead initiating terminal exists arcing point and acnode, circumferential weld intersects with this place, it is easy to cause existing defects in weld seam, affects water tank service life.
Summary of the invention
The technical problem to be solved is the defect existed for prior art, it is provided that a kind of novel inner end cap and the boxing method with interior bucket, to solve the problem that interior bucket easily leaks with inner end cap assembling difficulty and water tank.
For solving this technical problem, the invention provides a kind of water heater liner inner end cap, the junction of described inner end cap and bucket is provided with platform structure, and the end at platform structure is provided with inclined opening structure；The centerline direction of the inside end cap of described inclined opening structure tilts, and its gradient is 150 °～175 °.
Described platform structure is formed by die drawn, and external diameter is equal with interior bucket internal diameter, and error is-1.0～0mm.
Present invention also offers a kind of boxing method of water heater liner inner end cap and interior bucket, specifically include following steps:
1) the interior bucket two ends arcing point and acnode that are soldered vertical masonry joint are removed by lathe car；
2) by inclined opening structure guiding, inner end cap being made the fully-inserted interior bucket of platform structure, interior bucket is perfectly aligned with inner end cap；
3) carry out the boxing that fills silk in the outside of inner end cap and interior bucket junction, form weld seam.
Step 3) in adopt automatic feeding argon arc welding outside inner end cap and interior bucket junction.
The thickness of described inner bag is 1.2mm, and 5mm is removed by each car of lathe in interior bucket two ends.
Beneficial effect: platform and inclined opening structure are set in the inner end cap of the present invention so that inner end cap conveniently can insert interior bucket, Stability Analysis of Structures along platform structure；The welding method of the present invention adds compared with backing plate butt welding with tradition, saves backing material and manufacturing procedure, and backing plate and interior bucket welding sequence, saves production cost；Inner end cap platform structure and welding with filler wire method ensure that the quality of weld seam.The present invention has the advantage that docking convenience, saving cost and weldquality are high.
Accompanying drawing explanation
Fig. 1 is inner end cap of the present invention and Welding Structure schematic diagram.
In figure: 1 inner end cap, 2 platform structures, 3, inclined opening structure, bucket, 5 weld seams in 4.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is specifically described.
Fig. 1 show inner end cap of the present invention and Welding Structure schematic diagram.
The invention provides a kind of water heater liner inner end cap, the junction of described inner end cap 1 and bucket 4 is provided with platform structure 2, end at platform structure 2 is provided with inclined opening structure 3, make inner end cap 1 and interior bucket 4 conveniently along platform structure 2, inner end cap 1 can be inserted interior bucket 4 when being connected, Stability Analysis of Structures, will not produce docking uneven thus the problem that affects follow-up welding quality.
The centerline direction of the described inside end cap 1 of inclined opening structure 3 tilts, and its gradient is 150 °～175 °.
Described platform structure 2 is formed by die drawn, and external diameter is equal with interior bucket internal diameter, and error is-1.0～0mm,
Present invention also offers a kind of boxing method of water heater liner inner end cap and interior bucket, specifically include following steps:
1) the interior bucket 4 two ends arcing point and acnode that are soldered vertical masonry joint are removed by lathe car, there is substantial amounts of weld defect in weld seam arcing point and acnode, by Vehicle Processing operation, the arcing point of interior bucket 4 vertical masonry joint and acnode are removed, ensure that when follow-up boxing weldquality will not be subject to the impact of above-mentioned arcing point and acnode；
2) by inclined opening structure 3 guiding, inner end cap 1 being made the fully-inserted interior bucket 4 of platform structure 2, interior bucket 4 is perfectly aligned with inner end cap 1；
3) carry out the boxing that fills silk in the outside of inner end cap 1 and interior bucket 4 junction, form weld seam 5, platform structure 2 and employing welding with filler wire method, fully ensured that the quality of weld seam.
Preferably,
Step 3) in adopt automatic feeding argon arc welding outside inner end cap 1 and interior bucket 4 junction.
Embodiment:
