Production process of Rodless Cylinder:
During the operation of the rodless cylinder, if the deformation of the joint surface is small and uniform, you can replace the new bolts at the gap or increase the preload of the bolts appropriately. Tighten from the middle to both sides at the same time, that is, tighten the bolts from the sag or the place where the force is deformed. Theoretically, the preload of the bolt can be calculated by the formula d/L≤A, but because the data and measurement methods of this calculation are still under research and have not been promoted, they are mostly determined based on experience within the allowable stress of the bolt.
With the further development of technology during use, its polymer composite materials will gradually be successfully applied in the maintenance of rodless cylinders. Compared with traditional means, polymer composite materials have excellent temperature resistance, good pressure resistance, and better sealing performance, and have good plastic deformation. They will not solidify when heated, and the sealing film will not be damaged, thus ensuring the sealing of the sealing surface of the machine parts. In addition, it is easy to remove. The used sealing surface can be easily wiped off with anhydrous ethanol or without adhering to the sealing surface. Due to its excellent performance, it is gradually favored by more and more rodless cylinder companies.
During the production process of rodless cylinders, inlet and outlet ports will be effectively set on the end cover. During operation, some end covers are also equipped with buffer mechanisms. Sealing rings and dust rings are set on the rod side end cover to prevent air leakage from the piston rod and prevent external dust from mixing into the cylinder. A guide sleeve is set on the rod side end cover to improve the guiding accuracy of the rodless cylinder, bear a small amount of lateral load on the piston rod, reduce the amount of downward bending when the piston rod is extended, and extend the service life of the rodless cylinder. The guide sleeve usually uses sintered oil-containing alloy and forward copper castings. In the past, the end caps were usually made of forgeable cast iron. To reduce weight and prevent rust, aluminum alloy die-casting is often used. Brass is used for micro cylinders.
