The maintenance of the crimping machine and its daily failure maintenance When crimping the crimping machine, place the joint in the center of the mold as much as possible, and do not press on the hexagonal nut. Prevent tools and other foreign objects from entering the press head. Each time after the work is completed, the eight mold bases must be opened to the maximum extent, so that the spring can be in an open state and the spring can be maintained, and the oil cylinder is also in a pressure relief state to extend the life of the oil seal. The most important steps for the operation of the crimping machine Maintenance of the pipe press: The hydraulic oil in the oil tank should be replaced when it exceeds the time limit specified by the hydraulic oil manufacturer, or the oil level gauge should be checked visually. If the hydraulic oil is oxidized and darkened, it must be replaced. Frequently inject anti-wear lubricant into the moving surface of the mold base. During non-pressing machine working hours, please cover the dust cover to prevent debris from falling into the mold base Hose crimping machine is a kind of special hydraulic equipment that rivets high-pressure hose and metal pipe joints together by cold extrusion. According to the structure, it is divided into: four-post crimping machine, ram crimping machine and ring crimping Three kinds of machines. Among them, the ring crimping machine is popular in the market because of its simple structure, small size, material saving, low price, and high power conversion rate. However, the ring crimping machine also has its shortcomings. The tapered layer of the crimped workpiece will peel off and will enter the cylinder block and the working surface of the mold base along the eight expansion joints of the eight-part mold base, and it is not easy to clean, although it is through the opening of a chip hole at the front end of the cylinder and an additional installation in front of the piston Measures such as non-standard dust-proof ring still cannot cure the scratches on the inner wall of the cylinder and the working cone of the mold base. The choice of anti-wear hydraulic oil in the crimping machine and pipe pressing machine is good or bad, which has a great impact on the working efficiency and service life of the equipment. It can be said that it is an invisible hazard in the crimping machine and the pipe pressing machine. Developed on the basis of anti-oxidant hydraulic oil, it has alkaline high zinc, alkaline low zinc, neutral high zinc type and ashless type products. They are all divided into 22, 32, and 32 according to the 40'C kinematic viscosity. 46 and 68 four grades. The crimping machine and the pipe pressing machine use No. 46 anti-wear hydraulic oil. When crimping with crimping machine and pipe crimping machine, the crimping speed should not be too fast, which can easily cause damage to the inner rubber and breakage of the steel wire layer, and cause premature damage to the hose during use. In actual work, when replacing the high-pressure hose, the length of the selected hose, the number of steel wire layers, the shape and size of the joint should be reasonable, and the degree of bending of the hose should be minimized. Most of the damage of the high-pressure hose is caused by improper production. .
