Description

Technical Field

[0001] The present invention relates to the technical field of bicycle accessory processing, and in particular to a tube expanding device for the production of off-road bicycle handlebars. Background Art

[0002] Bicycle handlebars mainly have the following types: straight handlebars, which are the most common type of handlebars and are suitable for various types of cycling. They are located in the middle of the frame, allowing the rider to maintain an upright posture and are suitable for long-distance cycling and road racing. Drop handlebars, which bend backward, enabling the rider to lower the center of gravity and improve stability when going downhill. Drop handlebars are usually used for mountain bikes and other bicycles that require more control. Aerodynamic drop handlebars, which are lower than drop handlebars, further lowering the rider's center of gravity and facilitating cycling on rough terrain. Aerodynamic drop handlebars are usually used for mountain bikes, road bikes, and some downhill bikes. Butterfly handlebars, which are designed inspired by the airfoil of an airplane and are intended to reduce air resistance and increase speed. They are usually used in road bike races to reduce the rider's wind resistance. Tandem handlebars, which are designed for tandem bicycles, allowing the riders to cycle on both sides and share the load. They usually consist of two independent handlebars that can be adjusted in distance to accommodate different riders. Dirt jump handlebars, which are designed specifically for extreme bicycle sports such as dirt jumping and have a low position and a towering shape to keep the rider stable when jumping. Existing bicycle handlebars need to be tube-expanded during production and processing. Tube expansion is to apply a certain pressure to the bicycle handlebar tube through a tube expanding device. The method commonly used by predecessors is to insert a lifting expanding rod into the bicycle handlebar tube part to expand the bicycle handlebar tube part, and then extract the lifting expanding rod, and the diameter of the tube part will expand, so as to improve the sealing of the pipe orifice and extend the corrosion time of the pipe orifice. Currently, the method used for tube expansion of pipe parts is usually to manually insert an expanding rod into a metal tube to expand the metal tube.

[0003] When the existing expanding tube equipment for bicycle handle production is in use, as described in the patent application No. CN202121327123.8, which relates to the technical field of electric vehicle processing, specifically an expanding tube equipment for electric vehicle handle processing, including a main body. A shell is fixedly installed on the left side of the top surface of the main body. A hydraulic expanding tube is installed at the bottom right end of the shell. A hydraulic movable plate is installed on the right side of the top of the shell. A movable mold is fixed at the bottom end of the hydraulic movable plate through a screw. A fixed plate is fixedly installed in the middle of the top surface of the main body. A fixed mold is fixed at the top end of the fixed plate through a screw. A positioning transmitter is installed at the right end of the fixed plate. An outer shell is installed at the top right end of the main body. A double gear is installed on the left and right sides inside the outer shell through bearings. Chains are meshed with the outer walls of the large and small gears of the double gear, and the number of chains is two groups. A moving block is meshed equidistantly between the two groups of chains. The utility model is beneficial to form an assembly line operation and is beneficial to ensuring that the handle tube and the expanding tube structure are concentric before and during the expanding tube process. However, in the above technology, the positioning plate is a fixed structure, which is not convenient for quick adaptive transformation during the product expanding tube process. Therefore, we propose an expanding tube equipment for off-road bicycle handle production to solve the above problems. Summary of the Invention
