Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] As shown in the figure, the method for balancing the unbalanced spinning machine in this embodiment includes the following steps:

[0026] a. Establish a three-dimensional cylindrical coordinate system with the Z-axis of the three-dimensional coordinates on the axis line of the main shaft 1 of the laying machine, and use r to represent the radial distance coordinates from the midpoint of the three-dimensional cylindrical coordinate system to the Z axis, and use θ to represent the three-dimensional cylindrical coordinate system The azimuth coordinates of the midpoint, and represent the coordinates of the midpoint of the three-dimensional cylindrical coordinate system in the Z-axis direction with z, find out the coordinate position of the centroid of the spinning pipe 2 in the three-dimensional cylindrical coordinate system, and calculate the centro...

Abstract

A method for balancing a dynamic imbalance in a strand laying head, a strand laying head main shaft component, and a strand laying head. The strand laying head main shaft component comprises a main shaft (1) and a strand laying tube (2) fixed on the main shaft. A strand laying tube balancing block (3) for balancing eccentric quality of the strand laying tube is disposed on the strand laying head main shaft. The strand laying head comprises a case body (8), a motor (9), a driving bevel gear (11) connected to a motor rotor through a coupling, and a driven bevel gear (12) fixed on the main shaft. The driven bevel gear meshes with the driving bevel gear, and the main shaft is installed on the case body through a bearing. The strand laying head has small vibrations during work, can increase the rotating speed of a main shaft of the strand laying head, lower a failure rate of the strand laying head, and increase a service life of the strand laying head.

Description

technical field [0001] The invention relates to a steel rolling machine, in particular to a laying machine. Background technique [0002] The wire laying machine is the key equipment for spinning the rolled wire into coils for collection in high-speed wire rod production. The rolled piece is pinched by the pinch roller in front of the laying head, enters the high-speed rotating laying head, and is deformed by the force of the laying pipe, turning the high-speed straight-moving rolled piece into a nearly stationary circle. Among them, the rotating speed of the laying head can reach about 2200r / min, and the rotating diameter is large, about 1070mm, and the rolling line speed at this time can reach about 120m / s. For such a high-speed rolling condition, the laying head must have a high dynamic balance capability to reduce the vibration of the laying head. [0003] The existing methods to ensure the dynamic balance ability or reduce the vibration of the laying machine are as fo...
