Abstract
The utility model discloses a kind of hydraulic oil pipe, described hydraulic oil pipe comprises body and is socketed in the lining on body, and the enlarging of described body port is turned up and formed annular connecting head, and described annular connecting head and body are wholely set; Described annular connecting head and body joint form kink, and described kink is connected with lining interference; On described body, be also socketed with jointing.Form annular connecting head by the enlarging of body port is turned up and can make connecting head and body be wholely set, save welding procedure, such structure is more stable and firm, can bear higher pressure, and processing is simultaneously simple, improves work efficiency.
Description
Technical field
The utility model relates to a kind of hydraulic oil pipe.
Background technique
As everyone knows, existing hydraulic oil pipe comprises body and the connecting head that is arranged on body port, and described connecting head and body port are for being welded to connect.Such Placement processing is more loaded down with trivial details, and has higher requirement, particularly high-pressure oil pipe for welding procedure, if failure welding can cause leakage of oil.It is simple that prior art is badly in need of a kind of processing, well-set hydraulic oil pipe.
Model utility content
The purpose of this utility model is to overcome the defect existing in prior art, provides a kind of processing simple, well-set hydraulic oil pipe.
For achieving the above object, the technical solution of the utility model has been to provide a kind of hydraulic oil pipe, described hydraulic oil pipe comprises body and is socketed in the lining on body, and the enlarging of described body port is turned up and formed annular connecting head, and described annular connecting head and body are wholely set; Described annular connecting head and body joint form kink, and described kink is connected with lining interference; On described body, be also socketed with jointing.Form annular connecting head by the enlarging of body port is turned up and can make connecting head and body be wholely set, save welding procedure, such structure is more stable and firm, can bear higher pressure, and processing is simultaneously simple, improves work efficiency.
As preferably, described kink outer surface is connected with the interference of lining port internal surface.Such design is the further optimization to scheme.
As preferably, described body is three-dimensional lobster back, and described three-dimensional lobster back comprises one-body molded and spaced curved part and line part.Such design is the further optimization to scheme.
As preferably, described jointing is six rib joints.Such design is the further optimization to scheme.
Advantage of the present utility model and beneficial effect are: form annular connecting head by the enlarging of body port is turned up and can make connecting head and body be wholely set, save welding procedure, such structure is more stable and firm, can bear higher pressure, processing is simultaneously simple, improves work efficiency.
Brief description of the drawings
Fig. 1 is the utility model interference fit pre-structure schematic diagram;
Fig. 2 is structural representation after the utility model interference fit.
In figure: 1, body; 2, lining; 3, annular connecting head; 4, kink; 5, jointing; 6, curved part; 7, line part.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples are only for the technical solution of the utility model is more clearly described, and can not limit protection domain of the present utility model with this.
As Figure 1-Figure 2, a kind of hydraulic oil pipe, described hydraulic oil pipe comprises body 1 and is socketed in the lining 2 on body 1, and described body 1 port enlarging is turned up and is formed annular connecting head 3, and described annular connecting head 3 is wholely set with body 1; Described annular connecting head 3 forms kink 4 with body 1 joint, and described kink 4 is connected with lining 2 interference; On described body 1, be also socketed with jointing 5.
Described kink 4 outer surfaces are connected with lining 2 port internal surface interference.
Described body 1 is three-dimensional lobster back, and described three-dimensional lobster back comprises one-body molded and spaced curved part 6 and line part 7.
Described jointing 5 is six rib joints.
Adding man-hour, by task equipment and mould, by 180 ° of pipe end 8mm place's enlargings, in expanding end, support large bending part tubing, make tubing can form and firmly be connected sealing with lining 2 after processing, and gain in strength, product can not be lost efficacy under the effect of high compressive load.
With the product contrast that uses the welding of joint and tubing, its processing is simple, and automaticity is high, and efficiency is high, safety, reliably, can not form pollution, in ensureing to use function, reduces costs, and efficiency improves more than 3 times.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing from the front lower of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
