Problems solved by technology

According to the requirements of the technical manual of Morgan Corporation in the United States, the installation of the spinning tube 4 starts from the head of the spinning tube and installs fourteen clips in sequence. When the next few clips are installed, the tail of the spinning tube will "arch". , causing the gap between the spinneret and the spinneret to be too large and difficult to install
[0004]Due to the special shape of the spinning tube and high precision requirements, it takes nearly 50 minutes to install a spinning tube, which seriously affects the production rate
Due to the installation method of the spinning tube in production, it often takes a long time to replace the spinning tube, the spinning is disordered after the replacement of the spinning tube, the service life of the spinning tube is short, the labor intensity of the workers is high, and it is unsafe.

Embodiment

[0024] The quick installation steps of the spinning tube of the laying machine are as follows:

[0025] 1) Make every card position concentric, and choose the place with the largest curvature radius to give priority to installation

[0026] After repeated tests, it was found that the No. 8 clamp is the tail position of the deformation section as the positioning clamp, with large deformation and large curvature radius. Therefore, 14 clamps are installed in sequence from the head of the spinning tube to the tail of the spinning tube. The installation sequence is as follows: First install the first clip 6 to the position of the No. 8 card.

[0027] 2) The easy-to-deform area at the head and tail of the spinning pipe is preferentially installed

[0028] Because the head and the tail of the spinneret 4 are easily deformed, after the first clip 6 is positioned at the No. 8 clip, then the No. 1 clip will be installed on the head of the spinneret, and the No. Clip No. 14 2. Make th...

Abstract

The invention relates to an installation method for a spinning tube, in particular to a method for rapidly installing a spinning tube of a laying head. The installation position of a first clamp is determined on the spinning tube, a second clamp and a third clamp are installed at the head and the tail of the spinning tube respectively, and clamping holes of the clamps of the spinning tube are aligned with pin holes of a spinneret in a concentric mode; remaining clamps are installed at the two ends of the first clamp in sequence until installation of the remaining clamps is finished. The position of the first clamp is determined, then, the position of the clamp at the head and the position of the clamp at the tail are determined, and the clamping holes of the clamps of the spinning tube are aligned with the pin holes of the spinneret in the concentric mode; the clamps are sequentially installed from point to line in a zoned mode, error accumulation is eliminated to the greatest extent, and rapid installation is achieved.

Description

technical field [0001] The invention relates to a method for installing a spinning pipe, in particular to a method for quickly installing a spinning pipe for a laying machine. Background technique [0002] At present, in the production of high-speed wire rods, the spinning tube is an important part used for the wire rods to change from straight lines to curves. Therefore, replacing and installing the spinning pipe is a very important process of the steel rolling process. [0003] The installation method of the original spinneret: the spinneret 4 is fixed on the spinneret 1 by fourteen clamps, and the spinneret clip passes through the clip hole on the clip and the pin hole of the spinneret through the bayonet pin 3, and then Screw on the other side of the pin shaft with a screw and a cover, so that the clip firmly fixes the spinneret on the spinneret, and finally fixes it with the positioning block 5 as a limit. According to the requirements of the technical manual of Morg...
