Other feature and advantage of the present invention can further be explained from the detailed description below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is the schematic diagram of the preferred embodiment of the present invention.
The specific embodiment
With reference to shown in Figure 1, the invention provides a kind of inside reinforcement processing method for welding bicycle, this method is different with the way of the present outside increase of tubing reinforced structure, is the inside that reinforced structure is arranged on tubing, reaches purpose of the present invention thus.In the present invention, it mainly is welding at the cycle frame of magnesium alloy materials, yet, it will be appreciated by those skilled in the art that, method of the present invention is not limited to the tubing of magnesium alloy materials in fact, be equally applicable to the tubing of other material, also be not limited to the welding at cycle frame, it is equally applicable to the welding operation of other tubing.
At first, intercept one section magnesium alloy pipe as interior reinforcement tubing 1, vehicle frame for bicycle, because the size of vehicle frame is more fixing substantially, the scope that changes is little, so should in the length of reinforcement tubing 1 preferably be less than or equal to 50mm more than or equal to 30mm, for common such as 26 formula bicycles in the daily life, the length of reinforcement tubing 1 is that 40mm gets final product in preferred the selection.The external diameter of reinforcement tubing 1 equals the internal diameter of magnesium alloy tubing 2 to be welded in described, can easily interior reinforcement tubing 1 be attached in the tubing 2 to be welded like this, and be not easy to take place the situation that relative slip maybe can't embed.The pipe thickness of interior reinforcement tubing 1, just its wall thickness preferably more than or equal to the wall thickness of tubing 2 to be welded, can comparatively significantly increase the integral tube wall thickness at place to be welded like this, helps carrying out welding operation, has increased the intensity of weld bond.
Next, as shown in Figure 1, reinforcement tubing 1 in described is mounted to the inboard of that end that tubing 2 to be welded will weld, the end part aligning that the end of reinforcement tubing 1 and tape welding are taken over material 2 in making.The mode of inlaying can have multiple, in one embodiment, reinforcement tubing 1 in described can be inserted into described tape welding takes in the material 2, then two tubing are carried out extrusion operation, reinforcement tubing 1 and tape welding adapter material 2 is closely linked in making, do not relatively move and can not produce, the interior reinforced structure of Xing Chenging can not produce stress and concentrates thus, can not rupture before reinforcement.
After the inboard that reinforcement tubing 1 in described is mounted to that end that tubing 2 to be welded will weld, owing to can have some dislocation unavoidably between two tubing, so the end processing that needs following step that interior reinforcement tubing 1 and tape welding are taken over material 2 is smooth.Thus, internally the end of reinforcement tubing 1 and tubing to be welded 2 is carried out milling machine operation simultaneously.Milling machine operation not only can be smooth with the end processing of interior reinforcement tubing 1 and tape welding adapter material 2, and can also be used to adjusting the length of interior reinforcement pipe 1, makes it obtain best result of use.
