Abstract
The utility model belongs to the technical field of the welding steel pipe technique and specifically relates to a cold drawing precision welded steel tube for auto -parts, include the steel pipe body that is formed by cold drawing technology preparation, the steel pipe body has the central through hole, is provided with associated corrugate inside lining on the central through hole inner wall of steel pipe body, and the both ends of corrugate inside lining are stained with through glue and are connect on the inner wall of central through hole, and the material of corrugate inside lining is rubber, and the transversal annular of personally submitting of corrugate inside lining is provided with a plurality of steel rings in the corrugate inside lining, the utility model discloses a have a headspace between the trough of its corrugate inside lining of cold drawing precision welded steel tube for auto -parts and the steel pipe body, during silk waste ice in the corrugate inside lining, the volume can the grow, and can strut the corrugate inside lining of rubber material this moment, and the corrugate inside lining can expand towards the headspace, consequently, can effectually prevent to lead to the phenomenon of steel pipe body frost crack, the effectual problem of having solved the easy frost crack of northern car water pipe in winter because of inside silk waste ice.
Description
Technical field
This utility model relates to welded still pipe technical field, and especially a kind of auto parts machinery cold drawing accurate welds
Steel pipe.
Background technology
Auto parts machinery is to constitute the overall each unit of automobile and serve the product of automobile, and automobile brand is more now
Coming the most, car category also gets more and more, and generally automobile can be divided into heavy-duty car, minicar, visitor
Car three major types, along with the raising of people's living standard, the consumption of automobile is also got more and more by people, and automobile is joined
This market of part becomes increasing, and auto parts machinery manufactured factory also in development at full speed in recent years.
In the winter of northern China, owing to temperature is the lowest, the automobile being parked in outside for a long time is frequent
The problem that water pipe from freezing crack can occur, once the water pipe generation bursting by freezing of automobile can cause automobile engine to start,
Must be sent to maintenance, therefore, bring the biggest trouble, at present, a lot of car owners often take the most former
The way begun: bled off by the cooling water of electromotor after parking, directly adds hot water during startup in electromotor,
Although so there is certain effect, but the problem that there is complex operation.
Utility model content
The technical problems to be solved in the utility model is: in order to solve in prior art the winter in northern China,
Owing to temperature is the lowest, often there is the problem of water pipe from freezing crack in the automobile being parked in outside for a long time,
Now providing a kind of auto parts machinery cold drawing accurate welded still pipe, this cold drawing accurate welded still pipe is used as the water of automobile
Pipe can effectively prevent by bursting by freezing.
This utility model solves its technical problem and be the technical scheme is that a kind of auto parts machinery cold-drawn essence
Close welded still pipe, including the steel pipe body being made by cold-drawing technology, described steel pipe body has center and leads to
Hole, the central through hole inwall of described steel pipe body is provided with associated corrugated inner lining, described ripple
The two ends of shape liner are stained with by glue on the inwall being connected on described central through hole, the material of described corrugated inner lining
For rubber, the cross section of described corrugated inner lining ringwise, is provided with some steel rings in described corrugated inner lining.
In this programme, cold drawing accurate welded still pipe is used as the water pipe of automobile, and the trough of corrugated inner lining is with steel pipe originally
Having a headspace between body, when water freezing in corrugated inner lining, volume can become big, now can
Strutting the corrugated inner lining of quality of rubber materials, corrugated inner lining can expand towards headspace, therefore, it can to have
Effect prevent because internal water freeze and cause the phenomenon of steel pipe body bursting by freezing, steel ring can ensure corrugated inner lining not
Yielding.
Further, the outside of described steel pipe body is provided with antirust coat.
Further, described steel ring is equidistantly distributed along the axis of described corrugated inner lining.
The beneficial effects of the utility model are: auto parts machinery cold drawing accurate welded still pipe of the present utility model its
Between trough and the steel pipe body of corrugated inner lining, there is a headspace, when the water in corrugated inner lining is tied
During ice, volume can become big, now can strut the corrugated inner lining of quality of rubber materials, and corrugated inner lining can be towards in advance
Spacing expands, and therefore, it can effectively prevent from causing the phenomenon of steel pipe body bursting by freezing because internal water freezes,
The problem effectively solving the north of china in winter easy bursting by freezing of automobile water pipe.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is the schematic diagram of this utility model auto parts machinery cold drawing accurate welded still pipe.
In figure: 1, steel pipe body, 101, central through hole, 2, corrugated inner lining, 3, steel ring, 4, antirust
Coating.
Detailed description of the invention
Presently in connection with accompanying drawing, this utility model is described in further detail.These accompanying drawings are showing of simplification
Being intended to, basic structure of the present utility model is described the most in a schematic way, therefore it only shows and this utility model
Relevant composition.
Embodiment 1
As it is shown in figure 1, a kind of auto parts machinery cold drawing accurate welded still pipe, including being made by cold-drawing technology
The steel pipe body 1 become, described steel pipe body 1 has central through hole 101, and the center of described steel pipe body 1 leads to
Being provided with associated corrugated inner lining 2 on the inwall of hole 101, glue is passed through at the two ends of described corrugated inner lining 2
Water is stained with on the inwall being connected on described central through hole 101, and the material of described corrugated inner lining 2 is rubber, described
The cross section of corrugated inner lining 2 ringwise, is provided with some steel rings 3 in described corrugated inner lining 2.
The outside of described steel pipe body 1 is provided with antirust coat 4.
Described steel ring 3 is equidistantly distributed along the axis of described corrugated inner lining 2.
Auto parts machinery cold drawing accurate welded still pipe the most of the present utility model is used as the water of automobile
Pipe, has a headspace, when corrugated inner lining 2 between trough and the steel pipe body 1 of corrugated inner lining 2
In water freezing time, volume can become big, now can strut the corrugated inner lining 2 of quality of rubber materials, corrugated inner lining
2 can expand towards headspace, therefore, it can effectively prevent from causing steel pipe body 1 because internal water freezes
The phenomenon of bursting by freezing, when ice-out in corrugated inner lining 2, the corrugated inner lining 2 of quality of rubber materials can recover
Prototype, steel ring 3 can ensure that corrugated inner lining 2 is unlikely to deform.
Above-mentioned is enlightenment according to desirable embodiment of the present utility model, by above-mentioned description, and relevant work
Make personnel completely can in the range of without departing from this utility model technological thought, carry out various change with
And amendment.The content that the technical scope of this utility model is not limited in description, it is necessary to according to
Right determines its technical scope.
