Description

TECHNICAL FIELD

[0001] The present application belongs to the field of refractory material machining, and particularly relates to a machining method for ensuring smooth connection of a circular arc and a plane of refractory material. BACKGROUND

[0002] In the substrate glass industry, a large number of refractory materials of various specifications are needed to be machined, and the refractory materials are relatively hard. Therefore, ordinary cutters cannot meet the use requirements, and only custom-made cutters such as diamond cutters can be used. In the machining process, only a small cutting amount can be used for grinding, and the wear of the cutter is also relatively serious. Errors exist in cutter manufacturing, workpiece manufacturing, workpiece clamping, and cutter setting. If the theoretical value is used to process the circular arc angle, overcutting will occur at the junction of the circular arc surface and the plane, and an edge will be generated. The equipment precision is required to be high, and the generation of edges is not allowed. In particular, at the junction of the mounting plane and the circular arc, the smooth connection of the plane and the circular arc surface is required. However, in actual processing, concave and edge phenomena often occur at this position, which leads to the fact that the equipment precision cannot meet the use requirements. SUMMARY

[0003] The present application belongs to the field of refractory material machining, and particularly relates to a machining method for ensuring smooth connection of a circular arc and a plane of refractory material.

[0004] To achieve the above-mentioned purpose, the following technical solutions are adopted in the present application:

[0005] In a first aspect, a machining method for ensuring smooth connection of a circular arc and a plane of refractory material comprises the following steps:

[0006] S1: moving a cutter to the upper surface of the refractory material to be machined, keeping the cutter and the upper surface at a first preset gap, placing a standard thickness plug gauge into the first preset gap, slowly moving the cutter downward until the standard thickness plug gauge slides with resistance, completing the cutter setting of the upper surface of the refractory material to be machined and calculating the cutter setting error value of the thickness, and compensating the cutter setting error value of the thickness into the machine tool;

[0007] S2: adding a first adjustment amount to the cutter setting error value of the thickness to obtain a first machining allowance, and compensating the first machining allowance into the machine tool;

[0008] S3: moving the cutter to the side surface of the refractory material to be machined, keeping the cutter and the side surface at a second preset gap, placing a standard thickness plug gauge into the second preset gap, slowly moving the cutter to the side surface until the standard thickness plug gauge slides with resistance, completing the cutter setting of the side surface of the refractory material to be machined and calculating the cutter setting error value of the width, and compensating the cutter setting error value of the width into the machine tool;

[0009] S4: a second machining allowance is obtained after adding a second adjustment amount to the width tool setting error value, and the second machining allowance is compensated in the machine tool;

[0010] S5: the machine tool is started to move the tool towards the side surface at a preset step distance, and the tool is stopped when a scratch appears on the side surface, and the machine tool is restarted to machine the arc of the refractory material, and the arc of the refractory material is smoothly connected to the upper surface and the side surface after machining.

[0011] In some embodiments, the first preset gap is greater than 0.2 mm and less than 0.3 mm.

[0012] In some embodiments, the second preset gap is greater than 0.2 mm and less than 0.3 mm.

[0013] In some embodiments, the thickness of the standard thickness feeler gauge is 0.1 mm.

[0014] In some embodiments, the first adjustment amount is 0.02 mm to 0.05 mm.

[0015] In some embodiments, the second adjustment amount is 0.05 mm to 0.1 mm.

[0016] In some embodiments, the preset step distance is 0.02 mm.

[0017] In some embodiments, the step of maintaining the first preset gap between the tool and the upper surface specifically comprises that the distance between the tangent line of the tool arc of the tool and the upper surface is the first preset gap.

[0018] In some embodiments, the step of maintaining the second preset gap between the tool and the side surface specifically comprises that the distance between the tool side surface and the side surface of the refractory material to be machined is the second preset gap.

[0019] In some embodiments, before restarting the machine tool to machine the arc of the refractory material to be machined, the error values of the thickness and the width of the refractory material to be machined are measured and input into the machine tool.

[0020] Compared with the prior art, the present application has the following beneficial effects:

[0021] The application provides a processing method for ensuring smooth connection of a fire-resistant material arc and a plane, moving a tool to an upper surface of the fire-resistant material to be processed, keeping the tool and the upper surface with a first preset gap, putting a standard thickness plug gauge into the first preset gap, slowly moving the tool downward until the standard thickness plug gauge slides with resistance, completing the tool setting of the upper surface of the fire-resistant material to be processed and calculating a thickness tool setting error value, compensating the thickness tool setting error value into a machine tool, which can eliminate the thickness manufacturing error of the fire-resistant material and the manufacturing error of the tool; adding a first adjustment amount to the thickness tool setting error value to obtain a first processing allowance, compensating the first processing allowance into the machine tool, which can avoid overcutting on the upper surface due to tool wear when processing the arc, and make the arc and the upper surface smoothly connected; moving the tool to a side surface of the fire-resistant material to be processed, keeping the tool and the side surface with a second preset gap, putting the standard thickness plug gauge into the second preset gap, slowly moving the tool to the side surface until the standard thickness plug gauge slides with resistance, completing the tool setting of the side surface of the fire-resistant material to be processed and calculating a width tool setting error value, compensating the width tool setting error value into the machine tool, which can eliminate the width manufacturing error of the fire-resistant material and the manufacturing error of the tool diameter; adding a second adjustment amount to the width tool setting error value to obtain a second processing allowance, compensating the second processing allowance into the machine tool, starting the machine tool to move the tool to the side surface at a preset step distance, stopping the tool until scratches appear on the side surface, restarting the machine tool to process the arc of the fire-resistant material to be processed, and after the processing is completed, the arc of the fire-resistant material to be processed is smoothly connected with the upper surface and the side surface, which can avoid overcutting on the side surface of the fire-resistant material to be processed when processing the arc, and make the arc and the side surface smoothly connected. The application solves the processing defects of the existing fire-resistant material arc in the processing process, makes the arc and the plane at the joint smoothly connected, and avoids problems caused by the arc not meeting the design requirements in assembly.

[0022] Further, the first preset gap, the second preset gap, the thickness of the standard thickness plug gauge, the first adjustment amount, the second adjustment amount and the preset step distance are specifically parameter-limited, which can ensure that the processed fire-resistant material arc and the plane are smoothly connected without defects, and improve the overall quality and appearance effect of the product.

Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0035] In the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connected", "fixing" and the like should be understood in a broad sense, for example, can be fixed connection, can also be detachable connection, or integral; can be mechanical connection, can also be electrical connection, and can also be communication; can be direct connection, or indirect connection through an intermediate medium, can be the internal communication of two elements or the interaction relationship of two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0036] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0037] In the substrate glass project construction industry, various types of refractory materials of different specifications need to be processed. Due to the high requirement of equipment precision, no corners are allowed to be generated, especially at the intersection of the mounting plane and the circular arc, the smooth connection of the plane and the circular arc surface is required. In the actual processing process, recesses and corners often occur at this place, resulting in equipment precision that cannot meet the use requirements, such as Figure 1 and Figure 2 The corners R-1 at the intersection of the upper surface and the circular arc, and the corners R-2 at the intersection of the side surface and the circular arc are generated on the refractory material; as shown in Figure 3 , recesses are generated at the intersection of the upper surface 1 and the processed circular arc corner R, and recesses are generated at the intersection of the side surface 2 and the processed circular arc corner R.

[0038] The thickness 9 of the refractory material 8 to be processed has a manufacturing error, and the circular arc surface of the tool 6 also has a manufacturing error. Using the theoretical value to set the tool will generate a processing error. The method for eliminating the error value in the thickness direction is to measure the error between the actual value and the theoretical value of the material thickness, and to move the tool to the surface to be processed and to reserve a certain gap. Since the tool has a manufacturing error, the tool 6 is a circular arc surface, and the surface is plated with diamond particles, it is difficult to accurately measure the accuracy of the circular arc. If the tool is set according to the theoretical value, a phenomenon of overcut as shown in detail B of Figure 4 will occur. How to eliminate the manufacturing error of the tool to avoid the overcut phenomenon as shown in detail B of Figure 4 is the problem to be solved in the present embodiment. The width 10 of the refractory material 8 to be processed also has a manufacturing error, and the diameter of the tool 6 also has a manufacturing error. If the tool is set and processed according to the theoretical value, a phenomenon of overcut as shown in detail A of Figure 5 will occur, and the corner R-2 will be generated at the side surface of the processed circular arc corner R. The method for eliminating the error of the side surface setting tool is to move the tool 6 to the side surface of the refractory material 8 to be processed and to reserve a certain gap.

[0039] Therefore, the present embodiment provides a processing method for ensuring the smooth connection of the circular arc and the plane of the refractory material, comprising the following steps:

[0040] S1: as shown in Figure 6 and Figure 7 , the tool 6 is moved to the upper surface 1 of the refractory material 8 to be machined, a standard thickness plug gauge is put into the first preset gap 5, and the tool 6 is slowly moved downward until the standard thickness plug gauge slides with a certain resistance, the upper surface of the refractory material 8 to be machined is finished, the error between the theoretical value and the actual value is calculated to obtain the thickness 9 error value, and the error value is compensated in the machine tool to eliminate the manufacturing error of the workpiece thickness and the manufacturing error of the tool.

[0041] S2: after the manufacturing error of the workpiece and the manufacturing error of the tool are eliminated, the thickness direction is increased by 0.02mm-0.05mm based on the error value of the tool setting, so that the overcut phenomenon shown in detail B of Figure 4 is avoided when the arc is machined.

[0042] S3: as shown in detail D of Figure 8 , a standard thickness plug gauge is put into the second preset gap 4, and the tool 6 is slowly moved to the side surface 2 until the standard thickness plug gauge slides with a certain resistance, the side surface of the refractory material 8 to be machined is finished, the error between the theoretical value and the actual value is calculated to obtain the width 10 error value, and the error value is compensated in the machine tool to eliminate the manufacturing error of the workpiece width 10 and the manufacturing error of the tool diameter 12.

[0043] S4: after the manufacturing error of the workpiece width 10 and the manufacturing error of the tool diameter 12 are eliminated, the width 10 is increased by 0.05mm-0.1mm based on the error value of the tool setting, so that the first tool cannot machine the side surface during machining, and the error value can be reduced by 0.02 steps in the machine tool every time the tool is moved, until the side surface of the refractory material 8 to be machined has a slight scratch, the error value reduction is stopped, and the machining is restarted, so that the overcut phenomenon shown in detail A of Figure 5 is avoided when the arc is machined.

[0044] Specifically, before machining the arc, the error value of the thickness 9 of the refractory material 8 to be machined and the error value of the width 10 need to be measured in advance, as shown in Figure 6 , 3 is the excess amount that needs to be machined.

[0045] Specifically, the first preset gap 5 is greater than 0.2mm and less than 0.3mm, and the thickness of the standard thickness plug gauge is 0.1mm; in order to ensure smooth connection at the junction of the arc and the upper surface 1 of the refractory material 8 to be machined, the thickness 9 error value is increased by 0.02-0.05mm, so that the machined arc will not have corners at R-1, ensuring smooth transition.

[0046] Specifically, the second preset gap 4 is greater than 0.2 mm and less than 0.3 mm. In order to ensure smooth connection of the side surface, 0.05-0.1 mm is added to the tool error value of the width 10, the tool approaches the side surface at a step distance of 0.02 mm, until a slight scratch appears on the side surface 2 of the workpiece 8, the tool is stopped, and the machine tool is restarted to process the arc, so that the side surface 2 and the arc R are smoothly connected, and the corner at R-2 is avoided.

[0047] Specifically, the distance between the tangent of the tool arc 11 of the tool 6 and the upper surface 1 is the first preset gap 5.

[0048] Specifically, the distance between the tool side surface 7 and the side surface 2 of the refractory material 8 to be processed is the second preset gap 4.

[0049] The processing method for ensuring smooth connection of the arc and the plane of the refractory material provided by the embodiment can solve the problem that the arc and the plane cannot be smoothly connected at the intersection, and overcut processing or undercut processing occurs, caused by the workpiece size error, clamping error, tool setting error, tool manufacturing error, and machine tool processing error in the processing of the refractory material. The method changes the tool setting method, eliminates the processing error of the workpiece material itself, the tool manufacturing error, the workpiece clamping error, and the tool setting error, and processes the workpiece arc surface. The method solves the processing defects of the existing arc in the processing process, so that the arc and the plane can be smoothly connected at the intersection, and the problems caused by the arc not meeting the design requirements in assembly are avoided.

[0050] From the technical common sense, the application can be realized by other embodiments without departing from the spirit or essential characteristics. Therefore, the above disclosed embodiments are only examples, and are not the only ones, all changes within the scope of the application or within the equivalent scope of the application are included in the application.
