Description
Technical Field
[0001] This utility model belongs to the field of metal pressure processing, and in particular relates to the guide wheel and roll profile, guide and roll alignment, and guide and roll profile alignment. Background Technology
[0002] A rolling pass is formed by processing rolling mill rolls to create grooves, which are then assembled. Errors in the fit between the grooves and the standard rolling pass design can lead to production accidents and serious product quality issues. Similarly, a guide wheel pass is formed by assembling guide wheels. Errors in the fit between the guide wheels and the standard guide wheel pass can also cause production accidents and serious product quality problems.
[0003] If the guides and rolls cannot be horizontally or vertically aligned in space, it can also lead to production accidents and serious product quality problems.
[0004] The alignment of the rolling line is fundamental to metal pressure rolling. If the rolling lines of the guide wheel's working pass and the roll pass are not aligned, the workpiece will enter the pass, the design intent of the pass cannot be realized, and subsequent rolling parameter settings and many process requirements cannot be met, leading to poor product quality and production accidents. Incorrect alignment and correction between the roll pass and the guide wheel can also cause equipment damage.
[0005] The world's most advanced rolling mill equipment today employs complex equipment and operations for the correction of guide and roll profiles, guide wheel profiles, and rolling pass profiles, as well as the alignment of guide and roll profiles. This makes it difficult to use flexibly and is also expensive, with limited applications. Therefore, existing methods for aligning and correcting roll profiles and guides typically rely on experience and visual observation. Pre-rolling trial stock is used to assess the alignment and correction, allowing for adjustments. This existing technology suffers from high difficulty, large errors, increased costs, reduced product quality, frequent accidents, and disruptions to equipment operation. Utility Model Content

Detailed Implementation
[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0028] Please see Figure 1-7 This embodiment provides a guide and die alignment / correction instrument, including a guide template device 1 for calibrating guide wheels and guides, and a die template device 2 for calibrating roll dies and rolls, and for calibrating guide dies.
[0029] The guide template device 1 includes: a guide template 11, a first level 12, a fixing device 13, and a laser light 14. The upper half of the guide template 11 has a first hollow portion 110. The area of the first hollow portion 110 is the maximum area that meets the requirement that the outline of the guide template 11 is not easily deformed. The alignment with the hole template device 2 can be observed through the first hollow portion 110. The lower half of the guide template 11 has a first level mounting hole 111. The first level 12 is installed in the first level mounting hole 111. The shape of the guide template 11 conforms to the guide wheel hole shape. A laser light mounting hole 112 is provided at the center point of the guide template 11. A laser light 14 is vertically installed in the laser light mounting hole 112. The laser light 14 is detachable and can be installed on both sides. The fixing device 13 is installed on the guide template 11 below the laser light 14 and above the first level mounting hole 111.
[0030] The perforated template device 2 includes a perforated template 21 and a second level 22. The upper part of the perforated template 21 has a second hollow portion 210, which consists of two parts. A beam 216 is located between the two hollow portions 210.

The area of the second hollow portion 210 is the maximum area that ensures the guide template 101's outline is not easily deformed. The lower part of the perforated template 21 has a second level mounting hole 211, in which the second level 22 is installed. A laser alignment projection point groove 212 is provided at the center point of the perforated template 21, and the laser alignment projection point groove 212 is coated with color.
[0031] In a preferred embodiment of this invention, the guide template device 1 and the perforated template device 2 have the same level structure, both including a transparent container 30. The length, width, and height of the transparent rectangular container 30 are consistent with the first level mounting hole 111 or the second level mounting hole 211. The transparent container 30 is marked with horizontal and vertical scale graduations 31, and the transparent container 30 contains a colored liquid 32. The colored liquid 32 is a different color from the horizontal and vertical scale graduations 31, and the colors are two contrasting colors. When the colored liquid 32 is horizontally parallel and vertically perpendicular in space, its liquid level coincides with the horizontal long line of the horizontal and vertical scale graduations 31. The state of the colored liquid 32 can be observed through the transparent container 30, and the horizontal and vertical scale graduations 31 on the transparent container 30 indicate the state of the colored liquid 32, facilitating the adjustment and calibration of the horizontal parallelism and vertical perpendicularity of the guide and the roller.
[0032] In a preferred embodiment of this invention, the fixing device 13 includes two stainless steel pipes 131, which are welded to the guide template 11, thereby fixing the fixing device to the guide template 11. Steel wires 132 are inserted into each of the two stainless steel pipes 131 in a negative tolerance fit. One end of each steel wire 132 extends out of the stainless steel pipe 131 and connects to an operating rod 133, while the other end extends out of the stainless steel pipe 131 and connects to a steel plate 134. The length of the steel plate 134 is greater than the maximum value required by the guide wheel's groove process. A spring 135 connects the operating rods 133. The operating rods 133 are L-shaped, and the spring 135 can rotate freely on the operating rods 133 for its usable length. The lengths of the two stainless steel pipes 131 match the lengths of the two steel wires 132, and the maximum extension / retraction of the spring 135 meets the fixing requirements of the guide template device 1. The fixing device 13 of this embodiment fixes the guide template device in the guide wheel's bore. The operating lever 133 pulls the spring 135 and the guide template device 1 for disassembly and adjustment. The operating lever 133 is attached to the spring 135, which further enhances the fixing effect of the fixing device 13 on the guide template device 1.
[0033] In a preferred embodiment of this invention, rubber pads 136 with uneven surfaces are attached to both sides of the steel sheet 134. The rubber pads 136 serve to stabilize the fixing device 13 and the inner wall of the guide or the guide wheel.
[0034] In a preferred embodiment of this invention, the fixing device 13 further includes a spring stabilizing ring (not shown in the figure). The spring stabilizing ring is fixed directly below the laser lamp mounting hole 112 of the guide template 11 to stabilize and support the spring 135. The wire diameter of the spring 135 is in negative tolerance fit with the inner diameter of the spring stabilizing ring. During use, the spring stabilizing ring stabilizes the spring 135 and increases the fixing effect.
[0035] In a preferred embodiment of this invention, the upper and lower edges of the guide template 11 are acute angles (e.g., ...). Figure 2 (As shown by the position indicated by the letter A in the middle), this can improve the accuracy of the correction.
[0036] In a preferred embodiment of this invention, the die template 21 is a template 213 with a central die shape. In this embodiment, the template 213 is circular, and sharp corners 214 are connected to the upper and lower symmetrical ends of the template 213. The width of the sharp corners 214 is less than the minimum roll gap required by the rolling process. The edges of the template 213 are acute angles, and are tolerantly fitted to the roll die shape.
[0037] In a preferred embodiment of this invention, a rubber sleeve 215 is fitted onto the pointed corner 214. The pointed corner 214 and the rubber sleeve 215 fix the die template device 2 in the roll die.
[0038] In a preferred embodiment of this invention, both the guide template 11 and the die template 21 are made of stainless steel, and their shapes conform to the guide wheel die and the roll die, respectively, and are in tolerance fit.
[0039] The guide template 11 and the die template 21 are respectively shaped to conform to the guide wheel die and the roll die, thus achieving alignment.
