Description

Technical Field

[0001] This utility model relates to a centering template device for rolling bars and wires, belonging to the field of metallurgical tool technology. Background Technology

[0002] In the production of bars, round steel, and wire rods, the mill inlet guides primarily guide the workpiece into the rolling groove and support it during the rolling process. When the guides are not accurately aligned, the workpiece deviates from the center of the rolling groove, resulting in a single-sided bulge on the round steel. In severe cases, this can lead to failed material entry and steel piling. Therefore, the accuracy of the mill inlet guide alignment is crucial to reducing single-sided bulge defects on the round steel surface and minimizing steel piling quality accidents.

[0003] Traditional imported guide alignment mainly relies on manual visual inspection to determine whether the geometric centerline between the two guide wheels of the imported guide is aligned with the centerline of the roll groove. This guide alignment method has three obvious drawbacks: (1) Due to the angular deviation between looking up and looking down, it is difficult to ensure that the visual inspection height is level with the geometric centerline between the two guide wheels, and whether the guide is aligned depends on the subjective judgment of the operator. (2) Due to the difference in visual inspection angles among different operators, the accuracy of guide alignment is low, and the round steel surface is prone to developing ears after passing through the steel, requiring repeated machine stops for adjustment until the ear defects in the finished product are eliminated, which takes a long time. (3) The low accuracy of guide alignment can easily cause steel pile-up accidents, and the red steel rushing out of the roller table poses a safety hazard of burning the operators. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a rolling guide centering template device for steel bars and wire rods, thereby improving the centering accuracy of imported guides, reducing single-sided ear defects on the surface of round steel, and reducing steel stacking quality accidents.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A centering template device for rolling bars and wires includes a hole template, a hinge connection device, and a scale. The hole template is semi-circular, and the scale is I-shaped with graduations at the front end. The hole template and the scale are hinged together by the hinge connection device and fixed by connecting bolts.

[0007] As a preferred embodiment, the hole pattern template and the scale are symmetrical along the center line.

[0008] As a preferred option, the hole pattern template and the scale must be installed on the same center line.

[0009] As a preferred embodiment, the hole pattern template and scale can be rotated 270°.

[0010] Beneficial effects: Compared with the existing technology, this utility model has a simple structure and is easy to operate. It solves the problem of visual error in the centering operation of traditional guides, greatly improves the centering accuracy of imported guides, reduces the single-sided ear defect on the surface of round steel, and reduces steel stacking quality accidents.

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Detailed Implementation

[0015] Example 1: As Figure 1-3 As shown, a rolling guide centering template device for steel bars and wires includes a hole template 1, a hinge connection device 2, a scale 3, and connecting bolts 4. The hole template 1 is semi-circular, and the scale 3 is I-shaped with graduations at its front end. The hole template 1 and the scale 3 are hinged together by the hinge connection device 2. The hole template 1 and the scale 3 can rotate 270 degrees. The upper and lower ends of the hinge connection device 2 are fixed to the hole template 1 and the scale 3 respectively by the connecting bolts 4.

[0016] The die template 1 of this invention is consistent with the groove used in the rolling mill. Different die templates correspond to different rolling mill groove patterns. The length and size of the scale also vary depending on the size of the rolling mill. The ultimate goal is to ensure that the die template corresponds one-to-one with the rolling mill groove pattern and that the scale extends to the guide roller position to achieve centering. In use, align the die template 1 with the rolling mill groove, rotate the scale 3 to align with the guide roller position, and the center point of the scale 3 is the centering point of the guide roller. Adjust the rolling mill guide guide lateral movement screw until the distances on both sides of the guide roller to the center point of the scale 3 are equal, thus achieving centering.

[0017] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
