Problems solved by technology

[0004] However, there are the following problems in this inspection method of the large base of the finishing mill: First, since the cone box of the finishing mill is installed on the installation surface of the cone box of the large base, the inspection of the elevation of the large base by means of the reference plane is an indirect inspection method, and the measurement results The error that occurs is the sum of the systematic error of indirect measurement and the accuracy error of each datum itself
In short, the current inspection method for the large base of the finishing mill is difficult to ensure the installation accuracy

Embodiment 1

[0042] Such as Figure 1 ~ Figure 3 As shown, the embodiment of the present invention provides a tool for testing the installation accuracy of the large base of a high-speed wire rod finishing mill. The tool includes: a level 4 and an inspection bracket, wherein the inspection bracket includes: a first rod body 1 and a second rod body 2, And one end of the first rod body 1 and one end of the second rod body 2 are connected to each other at a first preset angle, and the first rod body 1 and the second rod body 2 are respectively attached to the two cone box mounting surfaces of the large base 7; the top surface 3 , is arranged at the junction of the first rod body 1 and the second rod body 2 , and the top surface 3 and the first rod body 1 and the second rod body 2 both form a second preset angle, wherein the level 4 is located on the top surface 3 . In addition, a reticle 5 is provided on the top surface 3, and the reticle 5 is located on a symmetrical plane of the inspection ...

Embodiment 2

[0048] Such as Figure 4 As shown, the embodiment of the present invention also provides a method for inspecting the installation accuracy of the large base of the high-speed wire finishing mill, which is applied to the above-mentioned tooling for inspecting the installation accuracy of the large base 7 of the high-speed wire finishing mill. The method includes:

[0049] Step 41, checking whether the levelness of the inspection bracket is within the first preset range;

[0050] In the second embodiment of the present invention, a level 4 can be used to check whether the levelness of the support is within the first preset range.

[0051] Step 42, when the levelness of the inspection bracket is within the first preset range, according to the first elevation value of the center point 6 of the roll box of the high-speed wire finishing mill and the distance value from the center point 6 to the top surface 3 of the inspection bracket, the inspection Whether the second elevation val...

Abstract

The invention provides a tool and method for testing the installation accuracy of the large base of a high-speed wire rod finishing mill, wherein the tool includes: a level and an inspection bracket, wherein the inspection bracket includes: a first rod body and a second rod body, and one end of the first rod body One end of the second rod body is connected to each other at a first preset angle, and the first rod body and the second rod body are respectively attached to the two cone box installation surfaces of the large base; the top surface is set at the connection between the first rod body and the second rod body , and the top surface forms a second preset angle with the first rod body and the second rod body, wherein the level is located on the top surface. The embodiment of the invention can simply, quickly and accurately test the installation accuracy of the large base of the high-speed wire rod finishing mill.

Description

technical field [0001] The invention relates to the field of metallurgical steel rolling, in particular to a tool and method for testing the installation accuracy of a large base of a high-speed wire finishing mill. Background technique [0002] The high-speed wire rod finishing mill is the core equipment of the high-speed wire rod rolling production line. The finishing mill is the finished product rolling mill of the wire rod production line. The precision of the equipment is an important guarantee for the quality and output of the finished wire rod. Its basic components include: cone box, roller box, coupling, large base, etc. A roller box is loaded into a cone box, and a certain number of cone boxes are installed on the large base in turn, and the left and right cone boxes are connected sequentially through couplings. In order to ensure high-speed and stable rolling in the finishing mill, it is necessary to keep the rolling centerlines of the roll boxes consistent. Ther...
