Servo rope type hot forging piece axial dimension detection apparatus

Abstract

Disclosed is a servo rope type hot forging piece axial dimension detection apparatus. The apparatus comprises a mobile dolly, the mobile dolly is configured on linear guide rails, the linear guide rails are fixed on an industrial aluminum section support, the mobile dolly is driven to move and the axial dimension of a hot forging piece is detected both through an AC servo main motor, the AC servo main motor is driven by a main motor servo driver and drives a grooved pulley to rotate, the grooved pulley drives a steel rope to move so as to drive the mobile dolly to perform reciprocating motion along the linear guide rails, the steel rope is tensioned through a rigging screw button and employs a closed loop, information of number of turns of a main motor is obtained through an encoder carried by the AC servo main motor itself so as to calculate and obtain the axial dimension of the hot forging piece forged on a forging press and forms closed-loop control, and the orientation of linear laser emitted by a green-light linear laser is adjusted by use of a rotating disk driving mechanism so as to perform marking positioning on the hot forging piece. According to the invention, non-contact real-time online detection and positioning of the axial dimension of the hot forging piece can be effectively realized, the precision is high, the response is fast, and the reliability is high.

Description

technical field [0001] The invention belongs to the field of dimension detection of hot forgings, and in particular relates to a servo rope-type axial dimension detection device of hot forgings. Background technique [0002] Large forgings are the key and basic parts for manufacturing heavy machinery and major equipment. With the acceleration of my country's industrialization process and the manufacturing environment of large forgings and its role in heavy equipment after processing, it is difficult and important to ensure the quality of manufacturing. In order to ensure the manufacturing accuracy of forgings, in addition to mastering temperature information, it is also necessary to know the dimensional parameters of forgings in real time, so as to reasonably determine the forging pressure and judge when to stop forging. At present, the length of the longest shaft forgings produced by hydraulic forging machines in my country has reached 21m. During the free forging process,...

AI Technical Summary

Problems solved by technology

Hot large forgings have large axial dimensions and high temperature, and the manual contact detection method is slow, low in precision and poor in working environment

The use of laser ranging sensors to detect the axial dimension of hot forgings is complicated in structure, high in cost, and difficult to install and debug; the current axial dimension detection device driven by belt transmission is complex in structure, and will be affected by the vibration and vibration during the operation of the detection device. The inertia of the detection device causes error accumulation, which affects the detection accuracy
