Description

Technical Field

[0001] The utility model relates to the technical field of wheel rim spoke hole processing, in particular to a dent punching device used for wheel rim spoke hole processing. Background Art

[0002] Motorcycle rim spoke hole processing generally uses rigid automated equipment, which utilizes a single-piston hydraulic cylinder and a rigid composite punch for the dimple punch. This type of equipment has low utilization and a narrow application range, only capable of processing a single rim specification. If any product parameter changes, this type of equipment becomes inoperable, increasing product scrap rates. To accommodate product series expansion and new product development, additional equipment with the required specifications is required, which inevitably increases fixed asset investment.

[0003] The primary purpose of the dimpling and punching device for wheel rim spoke holes is to improve wheel quality and processing efficiency. Specifically, through precise design and processing, the device can evenly machine spoke holes on the wheel rim, thereby improving the overall performance and handling of the wheel.

[0004] Traditional equipment is often unable to flexibly adjust to wheel rims of different diameters, resulting in low processing efficiency. Metal debris generated during the punching process is prone to splashing. Without effective protective measures, it is very easy to cause harm to the operator, which is not conducive to quickly adapting to the processing needs of different hole diameters and reducing the overall efficiency of the equipment. Finally, when adjusting the clamping mechanism or punching position, multiple steps and manual operations are usually required, which is not only time-consuming and labor-intensive, but also increases the labor intensity of the operator. In response to the above situation, we have introduced a dimpling and punching device for processing wheel rim spoke holes. Utility Model Content
