AI Technical Summary

Problems solved by technology

There are problems in this way: ①Because the detection and straightening are carried out on two devices respectively, the benchmarks cannot be accurately unified, and a large position error will inevitably occur
②The forgings are transported back and forth between the two equipments, resulting in long working hours and low efficiency
③Due to the long time of inspection and straightening, the temperature of the forgings decreases, and the forgings need to be reheated for many times, resulting in a large amount of scale loss and energy consumption of forgings
④ The material performance is unstable after repeated furnace reheating, which has a great impact on quality

Abstract

The invention discloses a detecting and straightening machine and method for shaft parts. The detecting and straightening machine comprises a console and a straightening machine body. The straightening machine body comprises a fixed work table and a movable main machine frame. The movable main machine frame can move on the fixed work table along the X axis and can feed data back to the console. A straightening hydraulic cylinder is arranged on the movable main machine frame and can straighten a workpiece. A rear bracket capable of moving along the Y axis is arranged on the rear side of the movable main machine frame. A measurement hydraulic cylinder is arranged on the rear bracket. A measurement rolling wheel is arranged below the measurement hydraulic cylinder. A displacement sensor for measuring the Y-axis movement amount and a displacement sensor for measuring the Z-axis movement amount are arranged on the movable main machine frame and the measurement hydraulic cylinder correspondingly. The displacement sensors can transmit information to the console. Detecting and straightening of the workpiece can be conducted on the same device and the same station through the same installation reference. When straightness detection is conducted on the workpiece, detection can be conducted on the workpiece on three-dimensional scale, and measurement errors are reduced.

Description

[0001] (1) Technical field [0002] The invention relates to the technical field of straightening machines, in particular to a straightening machine for detecting shaft parts and a straightening method. [0003] (2) Background technology [0004] With the rapid development of industrial technology, heavy machinery and equipment, large ships, generators (including steam turbines, wind generators, nuclear power), military products, etc. are increasingly demanding high-quality large shaft forgings. The meaning of high-quality forgings includes: ①high material mechanical properties ②high size and shape accuracy. This means that while ensuring the mechanical properties of the material, the amount of material processing must be reduced to save resources, save costs, and reduce energy consumption. [0005] Large shaft forgings are mostly obtained by hot forging. After hot forging, the material is tested at high temperature → straightened → re-tested → re-straightened until the straightness r...
