[0002] In the process of grinding the groove turning tool, the existing grinding concave sample plate (the existing grinding concave sample plate is completely the same as the required profile and size of the groove) and the groove turning tool are repeatedly compared and ground to ensure that the shape of the groove turning tool is completely consistent with the profile of the existing grinding concave sample plate, and the existing roll convex sample plate (the profile and size of the concave part of the existing grinding concave sample plate are completely the same as the profile and size of the convex part of the existing roll convex sample plate) and the processed roll groove are compared to ensure that the processed roll groove is consistent with the required groove. 1. If the groove turning tool and the existing grinding concave sample plate are completely fitted to form a precise fit (as shown in Figure 1 ), the groove processed by the tool will be smaller, and the convex sample plate cannot be completely put into the groove (as shown in Figure 2 ), resulting in unqualified groove processing.

[0003] 2. If the groove turning tool is intentionally ground a little larger (as shown in Figure 3 ), it can offset part of the processing error, but this will cause the existing grinding concave sample plate to be unable to completely fit with the groove turning tool, leaving a large gap, which needs to be observed from a distance, and the accuracy of the ground groove turning tool cannot be directly determined.

[0018] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0019] The existing grinding concave sample plate 1 is used to compare and grind the groove turning tool 2. After the existing grinding concave sample plate 1 is precisely matched with the groove turning tool 2 (as shown in FIG. 1), the rolling mill groove 5 processed by the groove turning tool 2 is too small. When checking, the existing rolling convex sample plate 3 cannot be completely put into the rolling mill groove 5 (as shown in FIG. 2). Figure 1 Figure 2 The reason is as follows: ​1. The existing grinding die plate 1 and the die-cutting tool 2 are perfectly fitted together to form a precision fit. In fact, it can be understood that the existing grinding die plate 1 and the die-cutting tool 2 are precisely fitted together. That is, the die-cutting tool 2 that has been ground must be smaller than the actual die size, and the processed roll die 5 will also become smaller. 2. During the machining process, the die-cutting tool 2 wears down, and the roll 4 and the die-cutting tool 2 will also experience elastic deformation.

[0020] This invention proposes to solve this problem by appropriately increasing the profile of the hole in the existing grinding template 1. When grinding the hole-shaped cutting tool 2, it is not necessary to grind the hole-shaped cutting tool 2 to be specially enlarged, nor is it necessary to observe it from a distance. It is only necessary to grind the hole-shaped cutting tool 2 until it completely matches the existing grinding template 1 to ensure the machining accuracy of the hole.

[0021] Example 1 In this embodiment, see Figure 4 The present invention provides a multifunctional hole-type lathe tool grinding template, comprising: The multi-functional grinding template 6 includes a grinding concave template 7 and a rolling convex template 8. The outline size of the grinding concave template 7 is larger than that of the rolling convex template 8. The grinding concave template 7 is used to fit and compare the die-cutting tool 2, and the rolling convex template 8 is used to fit and compare the rolling die 5. The multi-functional grinding template 6 has an L-shaped structure. The grinding concave template 7 is set on the outer side of the long side of the L-shaped structure, and the rolling convex template 8 is set on the inner side of the long side of the L-shaped structure. The axes of symmetry of the grinding concave template 7 and the rolling convex template 8 coincide on the same straight line.

[0022] For details regarding the above settings, please refer to [link / reference]. Figure 6 The L-shaped structure and the roll convex template 8 are used to position and correct the center distance of the initial die during the processing of the roll 4, and to inspect the center distance of the initial die after processing is completed.

[0023] Furthermore, a hole-type inspection protrusion plate 9 is provided on the outer side of the short side of the L-shaped structure of the grinding template 6. The outline dimensions of the hole-type inspection protrusion plate 9 are exactly the same as the outline dimensions of the roll protrusion plate 8.

[0024] For details regarding the above settings, please refer to [link / reference]. Figure 7 The punch plate 9 is used to inspect the accuracy of the roll die 5 after processing.

[0025] Furthermore, the outline dimensions of the roll convex template 8 are exactly the same as the outline dimensions of the required roll die; the amount by which the outline dimensions of the grinding tool concave template 7 are increased compared to the outline dimensions of the roll convex template 8 is an increase value D, and the increase value D ranges from 0.1 mm to 0.12 mm.

[0026] like Figure 8As shown, the commonly processed roll pass types 5 generally include three types: semi-circular pass type 10, semi-circular plus inclined side combined pass type 11, and trapezoidal pass type 12.

[0027] Furthermore, when machining the semi-circular hole 10, the dimensions of the grinding tool concave template 7 satisfy the following condition: the contour radius of the grinding tool concave template 7 = the contour radius of the roll convex template 8 + half of the increase value D.

[0028] Furthermore, such as Figure 10 As shown, when machining the semi-circular plus beveled combined hole type 11, the dimensions of the grinding tool concave template 7 meet the following conditions: the contour radius of the grinding tool concave template 7 = the contour radius of the roll convex template 8 + half of the increase value D, and the contour of the beveled edge of the grinding tool concave template 7 is half of the increase value D of the beveled edge of the roll convex template 8 moving outward in parallel.

[0029] Furthermore, such as Figure 11 As shown, when machining trapezoidal hole type 12, the dimensions of the grinding tool concave template 7 meet the following conditions: the trapezoidal profile of the grinding tool concave template 7 is half of the increase value D of the top edge and two inclined edges of the trapezoidal profile of the roll convex template 8 moving outward in parallel.

[0030] Currently, the common materials for rolls that can be machined using die-cutting tools are: ductile iron and semi-high-speed steel.

[0031] Furthermore, when machining roll 4 made of ductile iron, the increase value D is 0.1 mm.

[0032] In the above settings, the ductile iron roll 4 has good plasticity and small elastic deformation during processing, which also results in relatively less wear on the die-cutting tool 2. Therefore, when sharpening the tool, the contour size of the sharpening template 7 is increased by 0.1 mm relative to the roll die 5.

[0033] Furthermore, when processing the semi-high-speed steel roll 4, the increase value D is 0.12mm.

[0034] In the above settings, the semi-high-speed steel roll 4 has poorer plasticity than the ductile iron roll 4, resulting in slightly larger elastic deformation during processing and slightly greater wear on the die-cutting tool 2. Therefore, when sharpening the tool, the contour size of the sharpening concave template 7 is increased by 0.12mm relative to the contour size of the roll die 5.

[0035] Example 2 In this embodiment, a method for sharpening a multi-functional turning tool with a multi-functional hole-shaped tool grinding template as described above is proposed, comprising the following steps: S1. Determine the shape, size, and center distance of the required roll pass; S2. Determine the material of the required processing roll 4 and determine the increment value D; S3. Based on the values ​​determined in S1 and S2, design and process the multi-functional die-cutting tool grinding template, wherein the outline shape and size of the roll convex template 8 are exactly the same as the shape and size of the roll die to be processed; the outline shape and size of the grinding concave template 7 are calculated based on the increase value D and the relevant values ​​of the roll convex template 8; the distance between the roll convex template 8 and the grinding concave template 7 and the inner side of the short side of the L-shaped structure of the multi-functional grinding template 6 is determined based on the center distance of the roll die to be processed; S4. Grind the hole-shaped turning tool 2. During grinding, repeatedly compare the hole-shaped turning tool 2 with the grinding concave template 7 until the hole-shaped turning tool 2 and the grinding concave template 7 can fit together perfectly to form a precision fit. S5, See details Figure 5 The inner side of the short side of the multi-functional grinding template 6 is attached to the end of the roll 4, and the convex part of the roll convex template 8 is attached to the outer wall of the roll 4. Then the hole-shaped turning tool 2 is aligned with the grinding concave template 7 to complete the tool positioning of the initial hole shape. S6. During the processing, the inner side of the short side of the multi-functional grinding template 6 is attached to the end of the roll 4, and the convex part of the roll convex template 8 is attached to the initial die pattern on the roll 4 to correct the center distance. After processing, the center distance of the initial die pattern is checked using the multi-functional grinding template 6 (see details). Figure 6 ); S7, See details Figure 7 The shape and size of the roll die 5 are inspected using the die inspection convex template 9.
