Problems solved by technology

[0004] When the free forging method is used to forge the whole Y-shaped tee, the material utilization rate is low, resulting in a great waste of materials, and increases the production cost, and the production cycle is also long, which is not suitable for mass production
[0005] When die forging is used to forge the overall Y-shaped tee, a special mold is generally required, and each mold can forge one tee at a time, and the efficiency is relatively low
In addition, moving the metal raw material heated to about 1200 degrees Celsius from the heating furnace to the forging die is usually a long distance away, requiring special lifting gear, and once it falls during the process, the loss will be huge and the risk is high

Embodiment 1

[0038] Embodiment 1: as Figure 1 to Figure 10 As shown, a large-scale three-way high-efficiency automatic die forging device proposed by the present invention includes a base 100, four lower mold trolleys 200 that can move relatively, and an upper mold 600 connected to the four lower mold trolleys 200.

[0039] Wherein the base 100 includes four support rails 101 respectively corresponding to the lower mold trolley 200 and arranged in a cross shape, and a column 110 located in the middle of the base 100. The column 110 is arranged in a square column shape and is fixed at the center of the four support rails 101 , the end surfaces of the four lower mold trolleys 200 can abut against the side walls of the columns 110 . In addition, the upper surface of the support rail 101 is respectively provided with thin strip grooves and embedded wires 105. The four wires 105 are all connected with extension wires 1051. The extension wires 1051 are arranged on the ground. device.

Abstract

The invention discloses a large-scale three-way high-efficiency automatic die forging device and a die forging method thereof. The key points of the technical scheme are: a large-scale three-way high-efficiency automatic die forging device includes a base and four relatively movable lower dies trolley, the upper mold connected with the four lower mold trolleys; the base includes four support rails corresponding to the lower mold trolleys, and a column located in the middle of the base; the four lower mold trolleys include the main body of the lower mold, the main cavity, two There are two branch cavities, two blocking plates, chute, wheels and power device set on the lower end surface of the lower mold main body; the bottom of the upper mold is equipped with molds corresponding to the main cavity and branch cavities of the four lower mold trolleys. cavity. The invention uses the lower mold trolley that can move according to the preset track, automatically and quickly moves the high-temperature metal raw material from the heating furnace to the forging place, and can form multiple large-scale Y-shaped tee products at one time, with high production efficiency and higher production efficiency. safety.

Description

technical field [0001] The invention relates to the field of large-scale three-way die forging, in particular to a large-scale three-way high-efficiency automatic die forging device and a die forging method thereof. Background technique [0002] The large Y-shaped tee is one of the very important core components in the current thermal power generation and nuclear power generation systems. Its functions are, for example, used to transmit and divert high-temperature and high-pressure water vapor. With the continuous development of my country's power generation industry, the demand for large-scale tees is increasing. In addition to ensuring excellent performance, the requirements for tees are also higher and higher for processing cycle and production costs. Require. [0003] The current large-scale Y-shaped tee products mainly include two production methods: free forging and die forging. The free forging method is generally to use a large hydraulic press for free forging combi...
