Description

Technical Field

[0001] The utility model relates to a high-speed wire pre-finishing roll gap setting tool, belonging to the technical field of high-speed wire production equipment in the metallurgical industry. Background Art

[0002] High-speed wire pre-finishing rolling generally consists of four rolling mills, which are installed before the finishing mill. After the roll rings are replaced during pre-finishing rolling, the roll gap size of the installed roll rings needs to be checked and set. The checking and setting method is to use a feeler gauge after the new roll rings are replaced. Since high-speed wire rods are generally divided into at least three series, namely 5.5 series, 6.0 series, and 6.5 series, each series corresponds to a set of pre-finishing roll gap sizes, and the pre-finishing roll gap is generally above 3.0 mm, therefore, using a feeler gauge to check and set the roll gap size of each stand is very cumbersome, time-consuming and labor-intensive. Utility Model Content

[0003] The utility model aims to provide a high-speed wire pre-finishing roll gap setting tool, which can increase the speed of pre-finishing roll gap setting, save roll changing time, improve production efficiency, and solve the problems existing in the background technology.

[0004] The technical solution of the utility model is:

[0005] A high-speed wire pre-finishing roll gap setting tool comprises a base, a protrusion and a hanging hole. The base is provided with a hanging hole at the center. A plurality of protrusions are evenly arranged in the circumferential direction of the base. Each protrusion has a different thickness and is respectively matched with the width of the roll gap between the upper roll ring and the lower roll ring of a pre-finishing rolling mill. The base is engraved with a wire product specification mark and a pre-finishing rolling mill stand mark matching each protrusion.

[0006] The base is in the shape of a disc with a diameter of 30-50 mm.

[0007] The multiple protrusions evenly arranged in the circumferential direction of the base are all rectangular parallelepipeds, and the thickness of each rectangular parallelepiped matches the width of the roll gap between the upper roll ring and the lower roll ring of a pre-finishing rolling mill.

[0008] The number of the protrusions is four, and the thicknesses of the four protrusions respectively match the widths of the roll gaps between the upper roll rings and the lower roll rings of the four pre-finishing rolling mills.

[0009] The wire product specifications are identified as 5.5 series, 6.0 series and 6.5 series.

[0010] The pre-finishing rolling mill stand identifications that match the four protrusions are 15#, 16#, 17# and 18# respectively.

[0011] The utility model has the beneficial effects of increasing the speed of setting the pre-finishing roll gap, saving roll changing time and improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] In the figure: base 1, protrusion 2, 15# pre-finishing protrusion one 21, 16# pre-finishing protrusion two 22, 17# pre-finishing protrusion three 23, 18# pre-finishing protrusion four 24, hanging hole 3, upper roller ring 4, lower roller ring 5, roller gap 6. DETAILED DESCRIPTION

[0015] The present invention will be further described below by way of examples with reference to the accompanying drawings.

[0016] Refer to the attached Figure 1 , 2 A high-speed wire pre-finishing roll gap setting tool comprises a base 1, a protrusion 2 and a hanging hole 3. The base 1 is provided with a hanging hole 3 at the center, and a plurality of protrusions 2 are evenly arranged in the circumferential direction of the base 1. The thickness of each protrusion 2 is different and they are respectively matched with the width of the roll gap 6 between the upper roll ring 4 and the lower roll ring 5 of a pre-finishing rolling mill; the base 1 is engraved with a wire product specification mark and a pre-finishing rolling mill stand mark matching each protrusion 2.

[0017] In this example, the wire product specifications are divided into three series, 5.5 series, 6.0 series, and 6.5 series. There are four high-speed wire pre-finishing mills, and the numbers of each mill are 15#, 16#, 17#, and 18# respectively.

[0018] The roller high wire pre-finishing seam setting tool is made of 10mm thick steel plate by wire cutting. There are three of them, each corresponding to a product series, including:

[0019] The base 1 has a diameter of 40 mm and a central hanging hole 3 with a diameter of 10 mm. It is mainly used for hanging and storing tools. Four protrusions 2 are evenly distributed in the circumferential direction of each base 1. The length of the four protrusions 2 is 10 mm. The thickness of the four protrusions 2 matches the width of the roll gap 6 between the upper roll ring 4 and the lower roll ring 5 of a pre-finishing rolling mill. The overall weight is about 105 g. The specific data are as follows:

[0020] 5.5 series, 15# pre-finishing convex one 21 thickness 4.7mm, 16# pre-finishing convex two 22 thickness 3.5mm, 17# pre-finishing convex three 23 thickness 3.5mm, 18# pre-finishing convex four 24 thickness 3.1mm;

[0021] 6.0 series, 15# pre-finishing convex one 21 thickness 4.7mm, 16# pre-finishing convex two 22 thickness 4.1mm, 17# pre-finishing convex three 23 thickness 4.9mm, 18# pre-finishing convex four 24 thickness 3.2mm;

[0022] 6.5 series, 15# pre-finishing convex one 21 thickness 5.1mm, 16# pre-finishing convex two 22 thickness 4.4mm, 17# pre-finishing convex three 23 thickness 5.4mm, 18# pre-finishing convex four 24 thickness 3.7mm;

[0023] Refer to the attached Figure 2 , according to the product specification series to be produced, select the base 1 to be used. After the roll rings are installed in a certain batch, first insert the corresponding protrusions 2 in the tool between the upper roll ring 4 and the lower roll ring 5 of the pre-finishing rolling mill, then move left and right and observe whether there is a gap or it is too tight. If so, readjust the roll gap until it can move left and right with slight resistance, which means that the roll gap setting of this batch is completed.
