TECHNICAL FIELD
[0001] The utility model relates to an automatic equipment technical field, especially a kind of oil pipe joint stress relieving device. BACKGROUND
[0002] The fish-eye joint used on the vehicle models such as motorcycles, ATVs, off-road vehicles, electric vehicles and bicycles on the market belongs to one of the oil pipe joints. The existing oil pipe joints vary depending on the design and layout of the vehicle model, resulting in some differences in the oil pipe joints used. They are mainly divided into straight joints and curved joints.
[0003] The straight joint can be used without changing the direction or angle of the intake pipe. The carburetor and intake pipe can be aligned directly. The curved joint can be used to change the direction or angle of the intake pipe. The position of the intake pipe can be adjusted by bending or angle to adapt to different motorcycle designs or layouts (for example, in some motorcycle designs, the intake pipe may need to enter the carburetor from different angles. The curved joint can provide greater flexibility and adaptability).
[0004] The existing curved oil pipe joint has a common angle of 28°, 45° or 28°, 45°. The existing forming of the curved oil pipe joint generally involves 1, separate forming of the joint blank and core, 2, riveting the formed joint blank and core, and 3, bending the two ends of the riveted joint to the required angle (i.e. the riveted joint is straight first to ensure convenience during the separate forming and subsequent riveting process. The angle is then bent. The oil pipe joint is annealed to relieve stress before bending the straight joint. This ensures that the plasticity and toughness of the oil pipe joint are improved accordingly, thereby enhancing the tensile strength during subsequent bending.
[0005] The existing annealing stress relief treatment for oil pipe joints on the market is usually carried out by a mesh belt furnace or a box furnace. When the mesh belt furnace is used, the oil pipe joints are placed on the mesh belt. After the mesh belt with the oil pipe joints passes through a position similar to a resistance furnace, it is dropped to achieve the purpose of annealing stress relief. When the box furnace is used, the oil pipe joints are placed in the box furnace and heated to 400-500 degrees Celsius
[0006] Afterwards, it is taken out and re-cooled, so as to achieve the efficiency of stress relief; but the existing annealing stress relief realized by adopting the mesh belt furnace or the box-type furnace is to heat the whole product, thereby causing the heating annealing stress relief process of the oil pipe joint, and the power and labor are often wasted, and the whole manufacturing cost of the bent oil pipe joint is affected.
