Embodiment Construction
[0019] The specific implementation manner of the present invention will be further explained below in conjunction with the working principle. Referring to the accompanying drawings, the hydraulic cylinder 1 is integrated with the front support body 2, and the front support body 2 and the rear support body 10 are also integrated with the body pull rod 17. Mandrel 13 is installed on the central guide rod 12, and the model body 4, the front sizing die locking body 7 and the rear sizing die locking body 9 and mandrel 8 are installed on the guide rod 5, and can move on the guide rod 5.
[0020] When the pressure of the hydraulic cylinder pushes the piston rod 11 to move from left to right, see figure 1 and figure 2 , the connecting shaft 3 pushes the profiling body 4 to the right, the profiling body pushes the front sizing clamping body 7 to the right through the spring 6, and pushes the left mandrel tip 18 of the mandrel 8 into the front sizing clamping body Insert it into the ...

The invention discloses a pipe joint production method and a device thereof. The method adopts a single hydraulic cylinder and uses finalizing lock molds to move core molds from one support body to another support body in an irreversible way, extruding workpieces with the functions of the acting force and the reacting force to form required tee joints. The core molds are provided with core mold tips protruding outward, and the finalizing lock molds are provided with finalizing lock mold end twisters corresponding with the finalizing lock molds, wherein, in the extruding process the core mold tips enter the finalizing lock mold end twisters corresponding to the finalizing lock molds and are locked. The special device designed I the method comprises a mandrel and a hydraulic cylinder, and is characterized in that an anterior support body is connected with a posterior support body via an upper component pull rod and a lower component pull rod; the support bodies are connected with the molds via connecting shafts; the finalizing lock molds are connected with the core molds; a guide rod is connected between the anterior and the posterior support bodies and contact the molds via lock mold supporting pieces and core mold supporting pieces; the finalizing lock molds and the core molds are fixed on the guide rod in a sliding way. The invention has the advantages of space saving, energysaving, material saving, cost saving, simple structure and more user-friendly operation and maintenance.
Description
(1) Technical field: [0001] The invention belongs to a method and equipment for producing pipe joints. To be precise, what the present invention relates to is the production method and equipment for manufacturing related pipe joints such as stainless steel three-way pipes, four-way pipes or straight pipe peripheral protrusions (two), background technology: [0002] In the prior art, the production methods of pipe joints, especially tee pipes and four-way pipes, are usually manufactured by using a three-way hydraulic press (referred to as a three-way machine) with at least three hydraulic cylinders under the action of a sealing medium. The structure of the three-way machine is that three hydraulic cylinders are respectively installed in a solid gantry frame. Among them, one hydraulic cylinder is installed on the top of the gantry, and the other two hydraulic cylinders are placed on the left and right sides of the gantry. The pressure of the top hydraulic cylinder is usually...
