[CN 201621280271.8] Heavy hydraulic four-hammer radial forging tool
[CN 201621280271.8] Title of Heavy Hydraulic Four Hammer Radial Forging Tool: Application Number of Heavy Hydraulic Four Hammer Radial Forging Tool: CN 201621280271.8 Applicant: Dalian Design and Research Institute Co., Ltd. of Yizhong Group; China First Heavy Machinery Co., Ltd. Application Date: 2016-11-24 Patent Type: Utility Model The utility model discloses a heavy hydraulic four-hammer radial forging tool, it comprises an upper frame, a lower frame, 4 plunger cylinders, 4 hammer heads, 4 hammer heads, a plunger guiding device and a hammer head anti-rotation device; the upper frame and the lower frame are connected by pre-tightening bolts to form a closed frame, and the 4 hammer heads are respectively connected with the 4 hammer heads, and are respectively arranged on the upper frame and the lower frame in an "X-shape" to bear the force generated in the forging process; the cross-sectional area ratio of the hammer cylinder and the plunger cylinder is determined according to the magnification of the forging force. Compared with the upper and lower anvil forging methods of the original hydraulic press, the utility model adopts 4 hammers to apply load to the forgings at the same time, which can complete the forming process of heavy shaft parts more quickly, and make the forging accuracy of heavy shaft parts, The forging quality and forging efficiency are significantly improved, and the processing allowance after forging is significantly reduced. While saving materials, it can save working hours and reduce production costs to the greatest extent.
