Select the hose that needs to be buckled into a hose assembly and the fitting that matches the hose and the terminal used.<\/p>\n\n\n\n
It is necessary to confirm in advance:<\/p>\n\n\n\n
Key nodes here:<\/p>\n\n\n\n
Consequences of improper selection and matching:<\/p>\n\n\n\n
Incorrect assembly angles may result in:<\/p>\n\n\n\n
Cut the hose length (the hose cross section should be a smooth cross section perpendicular to the hose, do not cut diagonally and minimize burrs so as not to affect the use of the assembly) and prepare the joint.<\/p>\n\n\n\n
Improper cross-section may result in:<\/p>\n\n\n\n
The engraving of the joint logo, production must pay attention to the standard classification (processed, unprocessed and for which production tasks, and double-check the matching of the joint).<\/p>\n\n\n\n
According to the size of the hose and the type of joint to determine the length and thickness of stripping, stripping length should be neat and appropriate amount, stripping thickness should be uniform and appropriate amount, do not hurt the reinforcement layer of the hose.<\/p>\n\n\n\n
The consequences of stripping the amount of rubber (length and thickness) is not enough:<\/p>\n\n\n\n
The consequences that will be caused by the excessive amount of stripped rubber (length, thickness), the loss of the outer rubber layer protection, the reinforcement layer near the joint may be oxidized in advance, etc., reducing the service life;<\/p>\n\n\n\n
Stripping the enhancement layer may cause<\/p>\n\n\n\n
First clean the surface debris of both ends of the hose with an air gun, then clean the inner wall with a matching cleaning ball<\/p>\n\n\n\n
Inadequate cleaning after stripping the rubber may cause:<\/p>\n\n\n\n
The inner wall is not cleaned may cause<\/p>\n\n\n\n
Choose the right mold and set the buckling volume. When buckling hose joints: if the buckling size is too much, the rubber layer inside the hose will be broken, causing oil leakage; if the buckling size is too little, it will cause oil leakage and the joint will be flushed out by oil pressure.<\/p>\n\n\n\n
When buckling, 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 head of the buckling machine. Place the hose with the coupling in the proper position in the head of the press, so that the entire length is pressed at once. Press the buckling button to perform the buckling operation until the buckling head stops buckling and automatically opens the mold. Take out the buckled hose assembly, use vernier calipers to check the outer diameter size of the buckled joint jacket, if it does not match with the parameter table, fine tune the buckling amount until the next hose buckling meets the requirements. Re-confirm the buckling angle problem.<\/p>\n\n\n\n
The first assembly needs to pass the pressure test after the buckling is completed before starting batch buckling.<\/p>\n\n\n\n
Problems are found and adjusted in time to avoid batch substandard products. The general experimental pressure is twice the working pressure.<\/p>\n\n\n\n
Proper packaging to avoid scratching etc. of the product in transportation. Clear classification can improve subsequent work efficiency.<\/p>","protected":false},"excerpt":{"rendered":"
