Description

Technical Field

[0001] The invention relates to the technical field of rotary cutting devices, and in particular to a rotary cutting device and method for a dust cover head of an automobile shock absorber. Background Art

[0002] Suspension is the general term for all the force-transmitting connection devices between the frame and the axle of a car. Its function is to transmit the force and torque acting between the wheel and the frame, and to buffer the impact force transmitted to the frame or body by the uneven road surface, and reduce the vibration caused thereby, so as to ensure that the car can run smoothly. The typical suspension structure is composed of elastic elements, guide mechanisms and shock absorbers, etc., and some structures also have buffer blocks, lateral stabilizer bars, etc. The typical suspension structure is composed of elastic elements, guide mechanisms and shock absorbers, etc., and some structures also have buffer blocks, lateral stabilizer bars, etc.

[0003] The shock absorber is generally composed of a telescopic rod and a shock absorber rod. One end of the telescopic rod moves inside the shock absorber rod, and the other end is connected to the vehicle body. Since the telescopic rod will contact the outside world during the telescopic process, it is inevitable that dust and other impurities from the outside will be brought into the shock absorber rod. Since a sealing device is provided at the end of the telescopic rod inside the shock absorber rod, dust and other impurities will accelerate the wear of the sealing ring and cause damage to the shock absorber. Therefore, a dust cover is generally placed on the surface of the telescopic rod, which can isolate most of the dust from the telescopic rod.

[0004] The dust cover is generally made by blow molding. After the blow molding process is completed, there will be material heads left at both ends of the dust cover. In the prior art, the blow molding machine body will directly discharge the dust cover blank, and then the dust cover blank will be manually transferred to the cutting head equipment, and the material heads at both ends of the dust cover blank will be cut off to form the finished dust cover.
