Technical Field

[0001] The invention relates to the technical field of steel pipe processing, in particular to a burr removal device with a smoothness detection function for a gas spring steel pipe. Background Art

[0002] Gas spring is an industrial accessory that can play a supporting, buffering, braking and other functions. It is mainly used in covers, doors and other parts. It is also used in various automotive shock-absorbing components. The quality of a gas spring is mainly judged from the following aspects: First, its sealing. If the sealing is not good, oil leakage, air leakage and other phenomena will occur during use. The main cause of this problem is usually the burrs inside the gas spring steel tube. Therefore, the burrs inside the gas spring steel tube will directly affect the working performance of the gas spring.

[0003] Methods for burr removal usually include manual deburring, die deburring, grinding deburring, electrolytic deburring and other methods. Traditional manual deburring methods are usually not suitable for the processing of such precision parts. Due to the special structure of gas spring steel tubes, grinding deburring is also not suitable. Electrolytic deburring is more suitable for flat metals and metals of specific materials, and is not suitable for gas spring steel tubes. Therefore, the processing of gas spring steel tubes requires specific equipment to achieve the effect of burr removal, and in the process of processing, it is also necessary to avoid tearing injuries and ensure that the burrs fall off in time, so as to ensure the precision of the gas spring steel tube.
