Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment, in particular to a cutting device for a dust cover of a shock absorber. Background Art

[0002] In the suspension system of a car, the elastic elements are subjected to impact and vibrations. In order to improve the smoothness of the car's ride, a shock absorber is installed in parallel with the elastic elements in the suspension to attenuate the vibrations. In the suspension system, the shock absorber is the core component, and generally a hydraulic shock absorber is used. Its general structure includes a cylinder body with a piston working cylinder, an end cover matched with the cylinder body, a piston rod placed in the cylinder body at one end, an oil scraper seal and a guide seat that closely match the piston rod, and a dust cover for buffering that is circumferentially sleeved on the piston rod outside the cylinder body. The existing automobile shock absorber dust cover is generally processed by injection molding machine, but the demoulding is a technical difficulty in the injection molding machine, and the processing efficiency is relatively slow. In addition, there is a serious waste of raw materials in the injection molding process of the injection molding machine, which increases the production cost. In order to avoid the above-mentioned problem, there are blow molding machines on the market that blow mold the automobile shock absorber dust cover, and then cut the ports at both ends of the semi-finished automobile shock absorber dust cover. Due to the high requirements for the installation of the automobile shock absorber dust cover, it is now cut manually, and the cutting accuracy is not enough, resulting in a large number of unqualified defective products, affecting the installation efficiency of the automobile shock absorber dust cover.

[0003] For example, a cutting machine for processing automobile shock absorber dust covers with a publication number of CN203471148U belongs to the technical field of processing equipment. It solves the problem of low efficiency in the manual cutting of existing automobile shock absorber dust covers. The cutting machine includes a frame and a work surface fixed on the frame. Roller 1 and roller 2 are horizontally arranged on the work surface. Roller 1 is parallel to roller 2 and one end of roller 1 is connected to a motor. Two fixed seats are arranged between roller 1 and roller 2. A laser generating device is arranged on the work surface. The laser beam is emitted from the work surface between roller 1 and roller 2 and can perform laser cutting on both ends of the automobile shock absorber dust cover respectively. The laser generating device and the motor are both connected to the control box. The structure of the utility model will not squeeze or clamp the product when the automobile shock absorber dust cover is installed, and automatic cutting is realized. The structure is simple and the cutting precision is high.

[0004] The above technical solution has a small adaptability range in practical applications, and it is inconvenient to adjust when cutting dust covers of different specifications.

[0005] Therefore, it is necessary to invent a shock absorber dust cover cutout device to solve the above problems. Utility Model Content
