Description

Temperature-resistant transport vehicle for annular forge piece Technical Field The invention relates to the technical field of annular forging transfer devices, in particular to a temperature-resistant transport vehicle for annular forgings. Background After heat treatment, the annular forging is usually in a high temperature state and needs to be transported to the next working procedure for processing or cooling. At present, a common transportation mode is to use a flat transport vehicle and simply position and support the forging by arranging V-shaped blocks or fixing brackets on the vehicle body. However, this approach suffers from significant technical shortcomings: 1. The high-temperature annular forging can be naturally cooled and radially contracted in the transferring process. The traditional fixed clamping or rigid support can obstruct the shrinkage process, so that huge thermal stress is generated in the forge piece, even deformation is caused, and the dimensional accuracy and mechanical performance of the product are seriously affected; 2. the natural cooling speed is low, the production period is prolonged, and uneven heat dissipation on the surface of the forging piece can also cause inconsistent tissue performance; 3.
