a spinning machine

Abstract

The invention provides a wire discharging machine. The wire discharging machine comprises a box body and a wire discharging head, wherein the wire discharging head comprises a main shaft, and the main shaft is mounted in a bore hole of the box body through a main bearing. The wire discharging machine further comprises an elastic mounting member, wherein the elastic mounting member is arranged on the box body, supports the main bearing and is used for enabling the main bearing to drive the main shaft to achieve the movement of a predetermined range in the bore hole along a predetermined direction. The elastic mounting member can offset vibration generated during the operation of the main bearing; a load caused by the high-frequency vibration and shock of the main bearing is reduced, the service life of the main bearing and the service life of the wire discharging head are prolonged, the operating efficiency of the wire discharging head is increased, and the production and repair costs are reduced. According to the embodiments of the invention, a flexible support is increased by the main bearing, and the high-speed operation is more stable, so that the wire discharging speed of the wire discharging machine can be increased, and then, the yield of a high-speed wire production line is increased.

Description

Technical field [0001] The invention relates to a high-speed wire rod production line in the field of steel rolling, and a wire laying machine that makes high-speed linearly moving hot-rolled wire rods form ring coils. Background technique [0002] At present, the high-speed wire rod production line that produces hot-rolled wire rod with a diameter of 5-25mm is generally used. After the hot steel billet is rolled by multiple rolling mills, it is finally rolled into a wire rod with a diameter of 5-25mm. The high-speed running wire forms a loop coil for collection. The maximum speed of the wire can reach 90-120m / s, and the speed of the output shaft of the laying machine can reach 1800 rpm. [0003] Reference figure 1 As shown, in the prior art, the main shaft 2 of the laying machine is installed in the box 4 of the laying machine through the radial thrust bearing 1 and the main bearing 3, and the front end of the main shaft 2 is connected with the spinning disk 5. The spinning tube...
