Abstract

The invention discloses a turnout forging and pressing die, comprising an upper die frame and a lower die frame, wherein the upper die frame and the lower die frame are buckled with a guide post by guide sleeves, an upper die sunk cavity is arranged on the upper die frame, an upper module is arranged in the upper die sunk cavity, a lower die sunk cavity is arranged on the lower die frame, a lower module is arranged in the lower die sunk cavity, and the upper module and the lower module are correspondent after the upper die frame and the lower die frame are buckled together; a drainage hole communicated with the lower die sunk cavity is arranged on the lower die frame; and an auxiliary module detaching device and a module fastening device are arranged between one end of the upper module and the upper die frame, a module fastening device is arranged between the side face of the upper module and the upper die frame, and module fastening devices are respectively arranged among one end of the lower module, the side face of the lower module and the lower die frame. According to the turnout forging and pressing die, the production efficiency is improved, the service life of the die is prolonged, and high production efficiency and convenience for change and maintenance are achieved.

Description

technical field [0001] The invention relates to a die, in particular to a forging die for a turnout used in railway traffic. Background technique [0002] With the rapid development of my country's railway traffic, the demand for turnouts has also increased. At present, turnouts are manufactured through forging molds and forging processes. Some of the current forging methods of turnouts use multiple fires, two-station extrusion rail waist, The forging method of point and surface pressing on the bottom of the rail, this forging method has high labor intensity, low efficiency, and unstable quality; another forging method that uses a template structure, three-station forging and one-time heating. If the force is large, it is easy to cause the lower mold to shift and the product to be wrongly molded. In severe cases, the mold will crack and cause economic losses. Contents of the invention [0003] The object of the present invention is to provide a turnout forging die with imp...
