Description

TECHNICAL FIELD

[0001] The utility model relates to a bicycle rim forming technical field, more specifically, it relates to a bicycle rim forming device. BACKGROUND

[0002] In the bicycle rim forming device technical field, the existing products have many technical problems to be solved, which seriously affect the production efficiency and processing quality, mainly reflected in the following aspects:

[0003] Firstly, the traditional rim forming device adopts three movable rollers to process the profile, which has obvious limitations. Since the installation position of the roller is relatively fixed, there is no flexible adjustment mechanism, and the pressure distribution cannot be accurately adjusted according to different specifications of the profile or processing technology requirements. Especially when processing profiles with different wall thicknesses or materials, the fixed pressure distribution may cause uneven forming, poor surface quality and other problems. This rigid design not only affects product quality, but also may cause material waste and low production efficiency.

[0004] Secondly, the replacement process of the roller in the prior art has serious operation difficulties. When replacing the roller, the equipment maintenance personnel needs to use various professional tools and sequentially disassemble a large number of fasteners. The operation process is complicated and tedious. This traditional disassembly and assembly method not only consumes a lot of manpower and time, but also increases the equipment downtime. Especially when different specifications of movable rollers need to be replaced for different process processing, the complicated disassembly and assembly process seriously affects the production efficiency, increases the maintenance cost and safety hazards.

[0005] In addition, some improved devices have increased quick disassembly and assembly functions in design, trying to improve the replacement efficiency of the roller through simplified mechanical structure, but these improved designs still have major defects. These quick disassembly and assembly mechanisms usually adopt simple connection methods, which face serious stability problems in actual use. First, the centrifugal force and vibration generated by the roller during high-speed rotation will cause the connection structure to loosen. Second, the pressure during the forming process will cause additional stress on the connection components. These factors together can easily cause the movable roller to be unstable or even fall off. Once this happens, it will not only affect the processing accuracy, but also may cause equipment damage and safety accidents. TECHNICAL CONTENT

[0040] When different specifications of the movable roller 3 and the forming roller 2 need to be replaced according to the process requirements, first, the operation sleeve 15 is rotated to drive the large gear 18 connected on one side to rotate, and then the large gear 18 drives the plurality of small gears 14 meshing therewith to rotate, and then the small gears 14 drive the screw sleeve 19 to select on the fixed plate 17. Since the screw sleeve 19 and the screw rod 13 are movably connected through threads, then the screw rod 13 drives the moving sleeve 16 to slide, and then the inner wall of the moving sleeve 16 no longer limits the outer end of the moving rod 24. Then, the adapter sleeve 8 is counterclockwise rotated, and then the adapter sleeve 8 drives the plurality of moving rods 24 slidingly arranged on the side wall to move, and then the inner wall of the fixed groove 25 extrudes one end of the moving rod 24. Since the end of the moving rod 24 and the round corner at the edge of the fixed groove 25 are processed, then one end of the moving rod 24 slides out of the fixed groove 25, and the other end of the moving rod 24 drives the moving spring 26 to stretch, at the same time, the adapter sleeve 8 drives the variable-diameter groove 22 to rotate.
