Homemade high pressure hose fittings

With the development of industrial automation, various types of high-efficiency hydraulic drive device to get increasingly widely used. In these devices moving (rotating) parts, medium and high pressure rubber hoses are essential, and sometimes a piece of equipment or an automatic processing line is necessary to use different lengths of hose dozens or  Hydraulic pipe fittings even one hundred or more. The current hose (with connector) only in a few specialized factory production, supply according to fixed length, often can not meet the actual production and maintenance needs. Especially in remote and rural areas, urgently case harder to get sources. To this end, Shanghai tractor chassis factory Zhangke Pei gay homemade rolled in a set of simple, high-pressure rubber hose connector tools are rolled into the hose fittings, the hydraulic planer, various combinations of machine tools and related vehicles, proof performance well, no leakage. A copy of the tool structure and rolling process described below. Its process as follows: 1) system hose jacket; 2) system with flared inner core tube; 3) roll forming trench coat. (1) Coat tool system shown in Figure 1. Crimping sleeve length will be reserved for two (copper or thin tube) set into the mandrel 1, then two semicircular clamping vise clamp blocks wide, then put on a mold with tapered bore 4 , with a hammer percussion shape. (2) The inner core tube rolling tool shown in Figure 2. The band rolled into a pagoda-shaped inner core tube (brass)
