Abstract
The invention discloses a method and a device for plasticity forming of a high-pressure hydraulic t-branch pipe joint. The device comprises a mold, a power plant and a control device. The method comprises that a solid rod as a blank material is heated to an extrusion temperature and then is put into a mold; through closing of an upper mold and a lower mold, two side end molds move oppositely; when the two side end molds move to required positions, end molds along a vertical direction move and then reach required positions; the end molds are released and then the molded high-pressure hydraulic t-branch pipe joint is taken out; and a blocked part in the pipe middle of the molded high-pressure hydraulic t-branch pipe joint is processed suitably so that the whole processing process is finished. Through utilization of a warm extrusion plasticity forming technology, overall strength is high; the strength of a straight pipe and the strength of a branch pipe part are same; and t-branch pipe joint strength requirements are guaranteed. Large-radian connection of branch pipes is adopted so that under the extrusion, solid bars enter into the branch pipes more easily and energy consumption reduction effects are obtained.
