Abstract
The utility model discloses a plug is assisted to engine water pipe bending, including outer protection jacket and the dabber of setting in outer protection jacket, outer protection jacket is the step shaft that first macroaxis and first staff are formed, and the dabber be the step shaft of second macroaxis and second staff component, first macroaxis is equipped with the recess, and second macroaxis axial sets up in the recess, forms the ring channel between second staff and the recess, having the through -hole that runs through the recess in the first staff, being equipped with connecting bolt in the through -hole, connecting bolt's screw rod and second macroaxis pass through threaded connection. Compared with the prior art, the utility model is used for during engine water pipe bending, protect engine water pipe shape through the ring channel of dabber and outer protection jacket formation and prevent that the engine water pipe warp, can realize the bending protection of mazda SKY1.01.52.0 engine water pipe.
Description
Technical field
The utility model relates to the technical field of metal tube brake forming, particularly the auxiliary plug of a kind of curved shape of engine water tube.
Background technology
When the metal tubes such as the straight pipe of circle are carried out cold bend(ing) processing shaping by use tube-bending machine, if the inner chamber of metal tube is empty, when the process that it is bent, the section deformation of pipe, thus cause metal tube to be diminished by cross section, curved position, not only making the flow of in use fluid reduce, also affect the outer shape of metal tube, in the industries such as high pressure pipeline, chemical industry, requirement to bend pipe section deformation is especially strict.
Engine water tube, when carrying out bending machining, due to the Structure Designing Problem of the auxiliary plug of curved shape of prior art, usually there will be the situation of engine water tube distortion, causes scrapping of engine water tube.
Summary of the invention
The purpose of this utility model is the deficiency being solved prior art problem, it is provided that the auxiliary plug of a kind of curved shape of engine water tube.
For achieving the above object, the utility model is implemented according to following technical scheme:
The auxiliary plug of a kind of curved shape of engine water tube; the mandrel comprising outer jointing jacket and be arranged in outer jointing jacket; described outer jointing jacket is the first big axle and the step shaft of the first little axle composition; mandrel is second largest axle and the step shaft of the 2nd little axle composition; described first big axle is provided with groove; second largest axle is axially disposed within groove; ring groove is formed between 2nd little axle and groove; have, in described first little axle, the through hole extending through groove; being provided with joint bolt in through hole, screw rod and the second largest axle of joint bolt are threaded connection.
Further, the end of the first described little axle is provided with the heavy hole that the bolt head with joint bolt matches.
Preferably, the diameter of the diameter axle little of first of described 2nd little axle is identical.
Compared with prior art; when the utility model is used for engine water tube brake forming; engine water tube shape is carried out protection and prevents engine water tube to be out of shape by the ring groove formed by mandrel and outer jointing jacket, it may be achieved the curved shape protection of Mazda SKY1.0/1.5/2.0 engine water tube.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described, it is used for explaining the utility model in this practical novel illustrative examples and explanation, but not as to restriction of the present utility model.
As shown in Figure 1, the curved shape of a kind of engine water tube of the present embodiment assists plug, the mandrel 2 comprising outer jointing jacket 1 and be arranged in outer jointing jacket 1, described outer jointing jacket 1 is the step shaft that the first big axle 1a and the first little axle 1b form, mandrel 2 is the step shaft that second largest axle 2a and the 2nd little axle 2b form, described first big axle 1a is provided with groove 3, second largest axle 2a is axially disposed within groove 3, ring groove 7 is formed between 2nd little axle 2b and groove 3, ring groove 7 prevents engine water tube to be out of shape between the groove 3 that is stuck in by the tube head of engine water tube in the big axle 1a of the 2nd little axle 2b and first, prevent having, in described first little axle 1b, the through hole 4 extending through groove 7, joint bolt 5 it is provided with in through hole 4, screw rod and the second largest axle 2a of joint bolt 5 are threaded connection.
As the improvement of the present embodiment, the end of described first little axle 1b is provided with the heavy hole 6 that the bolt head with joint bolt 5 matches.
As the improvement of the present embodiment, the diameter of the diameter axle 1b little of first of described 2nd little axle 2b is identical.
The technical solution of the utility model is not limited to the restriction of above-mentioned specific embodiment, and every technology distortion made according to the technical solution of the utility model, all falls within protection domain of the present utility model.
