Design and structure principle of hydraulic hose crimping machine The main body of the crimping machine and the hydraulic system are designed as a centralized assembly box structure, and there is a hose joint socket that can be connected to the pipeline of the hydraulic station on the box. Spare molds, common tools and other spare parts can be stored in the box. Figure 2.1 is the host structure diagram. The main machine of the tube shrinking machine is the hydraulic cylinder 1, the taper sleeve 8 and the piston rod 5 are connected with the back cap 6 as a whole, the punch block 9 and the center sleeve 10 are connected with the rear positioning plate 11 by the nut, and the high pressure of the hydraulic system is The liquid enters the piston cavity from the port, pushes the piston rod outwards, and presses the outer cone surface of the punch block through the inner cone surface of the cone sleeve 8, so that the mold is elastically contracted radially, and the metal joint is compressed to produce a certain amount of radial plasticity. Deformation to achieve the purpose of connecting the metal joint and the hydraulic hose. When the oil is supplied from the reverse oil port, the piston rod retracts, the taper sleeve releases the compression of the counter block, and the block recovers due to the elasticity of the spring, completing a crimping cycle of the joint. 1- Outer cylinder body; 2- Piston rod; 3- Positioning partner; 4- Cylinder liner; 5- Piston rod; ; 11-Locating plate; 12-Nut 2 shows the form of figure. Figure 2.2 shows the working principle and hydraulic system diagram of the tube shrinking machine. The tube shrinking machine is composed of a main machine and a hydraulic station. The main machine is composed of a cylinder 1, a piston rod 2. a taper sleeve 3 and a punch block 5; the hydraulic station is composed of a liquid pump 9, a filter 11, and a liquid tank 12. In order to meet the supporting requirements of underground working face operations, the hydraulic station is designed to provide hydraulic power with a primary gear pump station. It can also be matched with other hydraulic stations according to on-site operation conditions.
