Description

Technical Field

[0001] The utility model belongs to the technical field of machining tool technology, in particular to a machining tool for non-metallic material components. Background Art

[0002] Nowadays, in the CNC machine tool grinding and milling process, there are people who process hard and brittle non-metallic materials such as ceramics, glass or graphite due to individual needs.

[0003] The applicant's previously approved prior art patent, "Airtight Molding 3D Glass Continuous Forming Device", mainly includes: a closed furnace body, with exchange systems at both ends of the furnace body, and an airtight cavity inside the furnace body; an exchange system, which is arranged at both ends of the furnace body, and an external conveying channel is arranged between the exchange systems at both ends of the furnace body, each exchange system includes an inner airtight door arranged on the side of the furnace body and an outer airtight door arranged on the side of the external conveying channel, an airtight space is formed between the inner airtight door and the outer airtight door, and a displacement device is provided to push the carrier into or out of the furnace body Before the carrier is sent into the furnace, the inner and outer airtight doors at the head of the furnace are closed. After the airtight space is evacuated and the protective gas is introduced to the same environment as the airtight chamber, the inner airtight door on the side of the furnace is opened to push the carrier into the airtight chamber. Before the carrier is sent out of the airtight chamber, the inner and outer airtight doors at the tail of the furnace are closed, and the airtight space has been evacuated and the protective gas has been introduced to the same environment as the airtight chamber. The inner airtight door on the side of the furnace is opened to push the carrier into the airtight space to prevent the airtight chamber from mixing with the outside of the furnace. Air; an airtight cavity, arranged inside the furnace body, including an airtight cavity, an inner conveying channel in the airtight cavity, the inner conveying channel connects the airtight doors in the exchange system at both ends of the furnace body, and is provided with a slide rail as a track for the movement of the carrier plate. The airtight cavity is airtight and introduces protective gas. In addition, it is divided into a heating zone, a high-temperature forming zone and a cooling zone according to the process. At least one thermal insulation layer is provided in the heating zone and the high-temperature forming zone, and a thermal field is formed in the center of the thermal insulation layer. A heating element of a temperature required by the process procedure is provided in the hot field, and a cooling device is provided in the cooling zone. The high temperature forming area is provided with a pressurizing system; the external conveying channel is connected to the exchange system at the two ends of the furnace body; the pressurizing system is mainly composed of a pressure cylinder, a pressurizing shaft and a pressurizing column; in the utility model thus constructed, the flat glass to be formed is placed on the forming surface of the mold, and the mold is placed on the carrier, and the carrier enters the airtight cavity through the exchange system, and is preheated in the temperature rising area and subjected to the high temperature in the high temperature forming area to soften the glass in the mold, and is formed by the pressurization of the pressurizing system, and then is cooled in the cooling area, and then is sent out of the furnace body through the exchange system, and then demolded.

[0004] In the molding process of the molded three-dimensional glass mentioned above, it is necessary to soften the glass by high-temperature heating and fix it in the mold to obtain the required shape. As we all know, whether it is plastic injection molding, powder injection molding or die-casting molding, the mold is a metal mold. That is, metal molds are the most widely used molds at present. However, the three-dimensional glass hot pressing molding process does not use metal molds, because metal materials are easy to deform and soften at high temperatures, while graphite has high hardness, good conductivity, radiation protection, corrosion resistance, good thermal conductivity, low cost, and high temperature resistance. Graphite materials and metal materials have opposite properties when they are heated. The higher the temperature, the harder the graphite is, so there will be no deformation problem of graphite. Therefore, the three-dimensional glass hot pressing molding mold is made of graphite material, which can ensure the maximum precision. In addition, the difficulty of mold processing is also reduced. The graphite molds used in the current three-dimensional glass hot pressing process are all cut by CNC machine tools using dry processing methods, that is, no lubricant or coolant is used. In the process of graphite mold processing, graphite dust will be caused to fly in the factory area, and dust collection and exhaust equipment must be added to collect dust. However, since graphite dust particles are small and light, dust collection and exhaust equipment can only reduce the pollution of graphite dust, but cannot completely collect it. Moreover, since graphite itself is a highly conductive body, in addition to causing pollution to the factory environment, it is also likely to cause dust explosions and damage to electrical equipment.

[0005] Although graphite dust pollution can be avoided in the process of graphite mold processing and manufacturing by wet processing method, the existing metal cutting and grinding tools, as shown in the prior art 2, include a tool body, which has a blade part and a shank part. This kind of tool processes hard and brittle non-metallic materials such as graphite. Due to the high hardness of such materials, the tool wears very much, so the tool life is very short; secondly, the cutting edge is prone to form chip accumulation edges, which seriously reduces the processing quality. Thirdly, the chips are easily blocked in the chip removal groove of the tool, resulting in poor dust removal and seriously reducing the product quality. As shown in the prior art 3, the patent discloses a tool composite coating and a tool having the composite coating. The tool The composite coating includes a base layer coated on the tool body and a top layer located on the outermost side, the base layer is a diamond layer or a cubic boron nitride layer, the thickness of the base layer is 1 to 40 μm, the top layer is a tetrahedral amorphous carbon film layer and the thickness is 0.01 to 15 μm, the tool includes a tool substrate and the above-mentioned tool composite coating, and the tool composite coating provided by it and the tool having the composite coating deposit a multi-layer nano composite coating with high hardness, low friction coefficient, good bonding force and good high temperature resistance on the surface of the cemented carbide micro-tool to improve the wear resistance of the micro-tool. However, since the dust particles of hard and brittle non-metallic materials such as graphite are small and light, during the processing process, its dust will penetrate into the tool holder of the processing equipment with the splashing of cutting fluid, causing the clamping mechanism in the tool holder to be contaminated with dust, so that when replacing the tool, the precision may be affected due to contamination, and the lack of shutdown of the processing equipment in the unmanned operation plant due to the need to clean the tool holder cannot be avoided, and the shutdown of the unmanned factory will cause great losses.

[0006] For this purpose, the applicant of this case proposed a non-metallic material component processing tool, which mainly includes a tool body, the tool body includes a first rod and a second rod, the front end of the second rod has a processing part, the surface of the processing part is covered with a diamond grain layer, wherein a balance ring with an outer diameter larger than the first rod and the second rod is provided between the first rod and the second rod, and the first rod, the second rod and the balance ring are integrally formed, and the balance ring has a reflow groove at the end of the second rod. It can indeed improve the rotation stability of the tool and prevent the processing powder from contaminating the tool holder of the processing equipment. However, when the previous case processes non-metallic material components with a small gap (groove) size, the processing part of the second rod is matched with the size of the part to be processed, so that the outer diameter of the second rod is small (thin), which makes the strength (rigidity) of the second rod of the tool smaller. If the force applied to the non-metallic material component to be processed is improper (too large), the second rod will be deformed, or even damaged, or the precision of the non-metallic material component to be processed will be poor. Utility Model Content

[0007] The main purpose of the utility model is to provide a "non-metallic material component processing tool". The utility model is related to the processing tool and is particularly suitable for processing non-metallic material components.

[0008] The non-metallic material component processing tool of the utility model mainly includes a tool body, which is an integral structure and has a first rod part, a second rod part and a third rod part. A balance ring with an outer diameter larger than the first rod part and the second rod part is provided between the first rod part and the second rod part. The balance ring has a reflux groove at the end of the second rod part. The outer diameter of the third rod part is smaller than that of the second rod part, and the end thereof has a processing part. The surface of the processing part is covered with a diamond particle layer. In addition to improving the rotation stability of the tool, avoiding processing chips from contaminating the tool holder of the processing equipment and forcing the reflux of the cutting fluid, the tool processing part has a large strength (rigidity), which can avoid deformation and damage of the processing part and affect the precision.

[0009] The third rod processing part of the utility model has a V-shaped groove at its bottom end to facilitate the removal of powder and cutting fluid.

[0010] In view of the deficiencies of the prior art, the utility model provides a better tool structure, which makes the wet grinding and milling of hard and brittle non-metallic materials such as ceramics, glass or graphite more perfect. In addition to improving the rotation stability of the tool, avoiding the contamination of the tool holder of the processing equipment by processing powder and forcing the reflux of cutting fluid, the tool processing part has a high strength, which can avoid deformation and damage of the processing part and affect the precision.

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0027] This utility model is a new design of tool for machining hard and brittle non-metallic material components such as graphite, ceramics, glass, etc. Figure 1 A three-dimensional diagram of the first embodiment of the utility model tool, Figure 2 A side view of the first embodiment of the utility model tool and Figure 4 A side view of the tool of the utility model in the implementation state. As shown in the figure, the tool for processing non-metallic material components of the utility model mainly includes a tool body 1, which is an integral structure with a first rod portion 10, a second rod portion 11 and a third rod portion 12. The first rod portion 10 is used as a clamping part fixed to a tool holder 2 of a processing device. A balance ring 14 with an outer diameter larger than that of the first rod portion 10 and the second rod portion 11 is provided between the first rod portion 10 and the second rod portion 11 to improve the rotation stability (i.e., centrifugal balance) of the tool body 1. During the processing, when chips are splashed with the cutting fluid, they will be blocked by the balance ring 14 and will not penetrate into the tool holder 2 of the processing equipment, so as to avoid the clamping mechanism in the tool holder 2 being contaminated by chips during processing. The chip-contaminated tool holder 2 of the processing equipment is provided. The balance ring 14 has a reflux groove 15 at the end of the second rod 11 to force the splashing cutting fluid and chips to flow back to the bottom to avoid the clamping mechanism in the tool holder 2 being contaminated by chips. The chip-contaminated tool holder 2 of the processing equipment is provided. The outer diameter of the third rod 12 is smaller than that of the second rod 11, and the end thereof has a processing portion 13. The surface of the processing portion 13 is covered with a diamond grain layer 16 as a grinding processing area. Since diamond has the highest hardness and wear resistance among all cutting tool materials, and its friction coefficient is extremely low, the diamond grain layer is very suitable for processing components of hard and brittle non-metallic materials such as graphite, ceramics, and glass, and has a long service life. In this way, in addition to improving the rotation stability of the tool, preventing machining chips from contaminating the tool holder of the machining equipment and forcing the cutting fluid to flow back, since the second rod portion 11 and the third rod portion 12 are integrally formed, and the third rod portion 12 with a smaller machining size is only a small part of the size of the second rod portion 11, the strength (rigidity) of the machining portion 13 of the third rod portion 12 is improved, and it can also prevent the machining portion 13 from being deformed, damaged and affecting the precision.

[0028] See also Figure 3 As shown, the processing portion 13 of the third rod 12 of the present invention has a V-shaped groove 17 at its bottom end to facilitate the removal of powder and cutting fluid. In this way, the design purpose of the present invention is achieved.

[0029] The above-described embodiments are only preferred embodiments for fully illustrating the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or changes made by technicians in the technical field on the basis of the present utility model are all within the protection scope of the present utility model. The protection scope of the present utility model shall be subject to the claims.
