Description

Technical Field

[0001] The utility model relates to the technical field of cutting machines, in particular to a cutting machine for processing upper and lower fork parts of a bicycle. Background Art

[0002] When a bicycle is produced, the bicycle contains upper and lower forks. The upper fork connects the upper edge of the seat tube to the rear hook and the rear wheel axle. The lower fork connects the bottom bracket to the rear hook and the rear wheel axle. The front fork controls the front wheel and has a buffering and shock-absorbing effect. When the upper and lower fork parts of the bicycle are produced, the outer parts of the upper and lower forks of the bicycle contain waste, so the excess scraps need to be cut.

[0003] During the processing of the cutting machine, the parts will be placed on a fixing device, and the movement of the cutting device will be controlled by a robotic arm. Then the cutting device can cut off the excess scraps on the outside of the parts. However, when the excess scraps are frequently sheared, the excess scraps will be caused to fly away. After the flying scraps splash out and contact with the workers, they will cause injuries to the workers. Therefore, we proposed a cutting machine for processing bicycle upper and lower fork parts.
