Description

Technical Field

[0001] The utility model relates to the technical field of long shaft forging processing, in particular to a long shaft forging heat treatment device. Background Art

[0002] Long-axis forging heat treatment technology refers to the process of heat treatment of long-axis forgings. In the field of industrial manufacturing, long-axis forgings are usually used in ships, wind power generation, steam turbines, oil and gas and other fields, so the heat treatment technology of long-axis forgings is particularly important. Heat treatment can significantly improve the organizational structure of long-axis forgings, improve the uniformity and stability of its materials, and the mechanical properties, physical properties and chemical properties of heat-treated long-axis forgings will be improved to a certain extent. Heat treatment can also remove the welding stress and processing stress generated during the processing of long-axis forgings, reduce the brittleness of the material, and improve its plasticity, thereby reducing the risk of cracks and fatigue damage that may be caused.

[0003] In the prior art, a Chinese patent document with application number: 202322379886.2 discloses a heat treatment device for a fork shaft forging, including a lifting ring, two first lifting chains are fixedly connected to one side of the outer surface of the lifting ring, a first support is fixedly connected to the bottom of the two first lifting chains, a plurality of first clamping components are fixedly connected to the top of the first support at equal intervals, two second lifting chains are fixedly connected to one side of the outer surface of the lifting ring, a second support is fixedly connected to the bottom of the two second lifting chains, a second clamping component is fixedly connected to the top of the second support at equal intervals, and a fork shaft is placed on the top of the first support and the second support. In the utility model, the first clamping component can fix the heavier end of the fork shaft, and the second clamping component will be stuck in the circular groove of the fork shaft to fix the lighter end of the fork shaft, thereby fixing the fork shaft, ensuring the firmness of the fixation and preventing the fork shaft from falling during heat treatment.

[0004] However, the above technical solution requires the use of multiple first fixing components and multiple second fixing components to install and fix multiple shaft forgings, and nuts are required for locking. Due to the large number of shaft forgings, matching tools are required to perform the disassembly and assembly operations in sequence during disassembly and assembly. This has great limitations and workload, and the operation is cumbersome, which greatly reduces the processing efficiency of the shaft forgings. To this end, we propose a long shaft forging heat treatment device to solve the above problems. Utility Model Content
