Description

Technical Field

[0001] This invention relates to the field of milling cutter manufacturing, and more particularly to an electroplated forming milling cutter with an external water supply and internal multi-channel cooling structure. Background Technology

[0002] CNC machine tools for machining non-metallic brittle and hard materials use a large number of diamond grinding tools. Among them, the commonly used diamond forming milling cutters are generally less than 25 mm in diameter. Therefore, it is difficult to manufacture them as internally cooled products, or products with only a few cooling channels to play a local cooling role. In addition, the cooling water needs to undergo high-requirement circulation filtration during use, and the size of the powder (slag) is strictly controlled. The smaller the diameter of the milling cutter, the more difficult it is to meet the requirements.

[0003] Most existing milling cutters are made by powder metallurgy, electroplating, or brazing. Powder chips can easily clog between diamond particles, making chip removal difficult and the load heavy. They are not suitable for fine-particle diamonds, making it difficult to guarantee the surface quality of the machined material and resulting in low machining efficiency.

[0004] With the increasing demand for high-speed, high-efficiency, and high-quality grinding, solving the problems of sufficient cooling in the grinding zone and smooth chip removal has become crucial. At the same time, due to the significant differences in radial machining amounts at different axial parts of the form milling cutter, the form milling cutter is prone to shape loss. Therefore, resistance to deformation (delaying the rate of deformation loss) is also an important factor in improving the life of the form milling cutter. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an electroplated forming milling cutter with an external water supply and internal multi-channel cooling structure, so as to meet the requirements of sufficient cooling and chip removal for milling cutters with a diameter of less than 25 mm, and improve the milling cutter's resistance to deformation during the machining process.

[0006] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: an electroplated forming milling cutter with an external water supply and internal multi-channel cooling structure, comprising: a base body, a working ring base body, multiple diamond plating layers, a water inlet retaining ring, a water-blocking and slag-removing plate, and fastening screws; the working ring base body is sleeved on one end of the base body, the water inlet retaining ring and the water-blocking and slag-removing plate are respectively disposed at both ends of the working ring base body, the water inlet retaining ring is sleeved on the base body, the water-blocking and slag-removing plate is connected to the end of the base body through the fastening screws, the multiple diamond plating layers are wrapped around the circumference of the working ring base body, and diamond particles are radially arranged in a single layer on the diamond plating layers.

[0007] The beneficial effects of this invention are as follows: multiple diamond coating layers are arranged around the circumference of the working ring substrate, which helps to provide sufficient space between each cutting edge of the working ring substrate for water to flow through and to discharge (or contain) powder and debris. This transforms the external cooling water supply mode in the prior art into an internal cooling mode, improving cooling efficiency and ensuring that all working diamonds on each diamond coating layer can be adequately cooled. The single-layer diamond particle arrangement prevents powder and debris blockage between diamond particles in the circumferential direction, resulting in a low proportion of ineffective load and facilitating rigidity assurance for small diameter diamonds.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the base includes a base handle and a base assembly; the base handle and the base assembly are coaxially arranged, the working ring base is fitted with the base assembly with an interference fit, the inlet retaining ring is sleeved on the base assembly, and the water-blocking and slag-discharging plate is connected to the end of the base assembly away from the base handle by the fastening screw.

[0010] The advantages of adopting the above-mentioned further solutions are: the base shank facilitates the mounting of the milling cutter on the CNC machine tool, and the interference fit between the base assembly and the working ring base helps to improve the stability of the working ring base during machining and facilitates machining.

[0011] Furthermore, the working ring base includes a cutting edge mounting base and multiple cutting edge blocks; the cutting edge mounting base is a ring-shaped structure that is interference-fitted with the mounting part of the base, and the cutting edge blocks are strip-shaped structures with the same length as the cutting edge mounting base. The multiple cutting edge blocks are arranged around the outer peripheral surface of the cutting edge mounting base along the machining rotation direction of the milling cutter, and the multiple diamond coating layers are individually and correspondingly disposed on the multiple cutting edge blocks.

[0012] The beneficial effects of adopting the above-mentioned further solution are: along the machining rotation direction of the milling cutter, setting a single layer of diamond coating on the cutting edge block is beneficial to forming multiple diamond grinding edges on the outer periphery of the milling cutter. Each diamond coating in the working area of ​​the milling cutter has at most one diamond working at each point along the axial direction, effectively avoiding circumferential blockage of dust between diamonds, and making chip removal easy and fast.

[0013] Furthermore, the circumferential length of each point along the axial direction of the diamond coating layer is positively related to the radial length of the cutting edge block.

[0014] The beneficial effect of adopting the above-mentioned further solution is that it helps the working ring substrate to play a role in resisting deformation, thereby improving the milling cutter's resistance to deformation during the machining process.

[0015] Furthermore, the inlet baffle ring is an annular structure, and the area between the inner wall of the inlet baffle ring and the outer wall of the base assembly is an annular inlet. The annular inlet is a trumpet-shaped structure with the small diameter end near the base handle.

[0016] The beneficial effect of adopting the above-mentioned further scheme is that the cooling water enters the funnel-shaped annular outer water inlet, which is conducive to smoothly entering the working ring base under the action of centrifugal force and tilt angle, so as to achieve internal cooling of the working ring base.

[0017] Furthermore, the blade mounting base is provided with multiple water-passing and water-retaining grooves in the circumferential direction. Each water-passing and water-retaining groove is a funnel-shaped structure with its small diameter end close to the annular water inlet. Each water-passing and water-retaining groove is an axial through hole connected to the annular water inlet. Each water-passing and water-retaining groove is arranged between two adjacent blade blocks.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the funnel-shaped water storage tank facilitates the smooth flow of cooling water from the inlet to the end of the milling cutter, thereby enabling the entire milling cutter to be cooled axially.

[0019] Furthermore, the number of water storage tanks is the same as the number of diamond coating layers, and the axial length of the water storage tanks is equal to the axial length of the diamond coating layers.

[0020] The beneficial effect of adopting the above-mentioned further solution is that it helps to ensure that the diamond coating layer in the axial direction can be cooled, thereby improving cooling efficiency and cooling effect.

[0021] Furthermore, the blade mounting base is provided with multiple water outlets in the circumferential direction. Each water outlet is an axial through hole that connects the water storage tank to the outer diameter of the blade mounting base. Each of the multiple water outlets corresponds to a single water storage tank, and each water outlet is located between two adjacent blade blocks.

[0022] The beneficial effect of adopting the above-mentioned further solution is that setting the water outlet as a through hole allows each diamond coating layer, i.e. the diamond grinding edge, to receive a continuous supply of cooling water.

[0023] Furthermore, the ratio of the distance from the water outlet to the adjacent diamond coating layer to the distance between two adjacent cutting blocks is greater than or equal to 0.5 and less than or equal to 1.

[0024] The beneficial effects of adopting the above-mentioned further solution are: a suitable circumferential position of the outlet can prevent all the cooling water from being discharged in the area near the inlet, resulting in no water or little water near the end of the milling cutter, and can make the cooling water evenly distributed in all points along the axis.

[0025] Furthermore, the circumferential width of the outlet is less than 0.3 mm.

[0026] The beneficial effect of adopting the above-mentioned further solution is that the circumferential width of the water outlet is less than 0.3 mm, which is conducive to the axial and balanced distribution of cooling water. Attached Figure Description

[0039] The principles and features of the present invention are described below. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0040] like Figures 1 to 9 As shown, an electroplated forming milling cutter with an external water supply and internal multi-channel cooling structure includes: a base body 1, a working ring base body 2, multiple diamond plating layers 3, a water inlet retaining ring 4, a water-blocking and slag-removing plate 5, and fastening screws 6; the working ring base body 2 is sleeved on one end of the base body 1, the water inlet retaining ring 4 and the water-blocking and slag-removing plate 5 are respectively arranged at both ends of the working ring base body 2, the water inlet retaining ring 4 is sleeved on the base body 1, the water-blocking and slag-removing plate 5 is connected to the end of the base body 1 by the fastening screws 6, the multiple diamond plating layers 3 are wrapped around the circumference of the working ring base body 2, and diamond particles are radially arranged in a single layer on the diamond plating layers 3.

[0041] It should be noted that the water-blocking and slag-removing plate 5 can block the water in the water storage tank 23 from leaking out unnecessarily through the end of the milling cutter during normal operation, and can be easily opened for cleaning when cleaning the powder (slag) in the water storage tank 23, so as to ensure the smooth operation of the water outlet 24.

[0042] The working mechanism of this invention is as follows: The electroplated forming milling cutter is composed of multiple blades, with at most one diamond working at each axial point of each blade. There is sufficient space between each blade for water to pass through and for removing (containing) powder and debris. The cooling water is converted from external supply to a highly efficient internal cooling mode. All working diamonds on each grinding blade can receive sufficient and internally cooled cooling water. The single-layer diamond particle setting prevents powder and debris blockage between diamond particles in the circumferential direction. The proportion of ineffective load is low, which is conducive to ensuring rigidity for small diameter.

[0043] The hardness of the working ring matrix 2 is much lower than that of diamond, so its consumption rate is faster than that of the working diamond particles. That is, the radial diameter is always smaller than the diameter of the working diamond particles. In addition to providing support for the diamond backing, it does not affect the grinding and chip removal of the diamond particles. Microgrooves can be formed between the diamond particles in the axial direction of the grinding edge, which can serve as cooling and chip removal microchannels and facilitate the micro-mechanical crushing of the workpiece.

[0044] The annular inlet 7 is an unobstructed inlet, and its horn-angle design helps to increase the volume and flow rate of cooling water flowing into the water storage tank 23.

[0045] Since the larger the diameter of the working area of ​​the milling cutter, the greater the amount of machining it faces, setting the circumferential length of each point of the diamond coating layer 3 along the axial direction to be positively related to the radial length of the cutting edge block 22 can play a role in resisting deformation. That is, the larger the diameter of the point, the longer the circumferential diamond coating layer 3 is, and the greater the overlap of the circumferential diamond particles in the radial direction (the greater the overlap, the higher the concentration of diamond particles), which can increase the service life.

[0046] The beneficial effects of this invention are as follows: multiple diamond coating layers are arranged around the circumference of the working ring substrate, which helps to provide sufficient space between each cutting edge of the working ring substrate for water to flow through and to discharge (or contain) powder and debris. This transforms the external cooling water supply mode in the prior art into an internal cooling mode, improving cooling efficiency and ensuring that all working diamonds on each diamond coating layer can be adequately cooled. The single-layer diamond particle arrangement prevents powder and debris blockage between diamond particles in the circumferential direction, resulting in a low proportion of ineffective load and facilitating rigidity assurance for small diameter diamonds.

[0047] Preferred, such as Figure 3 As shown, the base 1 includes a base handle 11 and a base assembly part 12; the base handle 11 and the base assembly part 12 are coaxially arranged, the working ring base 2 is fitted with the base assembly part 12 with an interference fit, the inlet retaining ring 4 is sleeved on the base assembly part 12, and the water-blocking and slag-discharging plate 5 is connected to the end of the base assembly part 12 away from the base handle 11 by the fastening screw 6.

[0048] The advantages of adopting the above-mentioned preferred solution are: the base shank facilitates the mounting of the milling cutter on the CNC machine tool, and the interference fit between the base assembly and the working ring base helps to improve the stability of the working ring base during the machining process and facilitates machining.

[0049] Preferred, such as Figure 2 , Figure 5 and Figure 6 As shown, the working ring base 2 includes a cutting edge mounting base 21 and multiple cutting edge blocks 22; the cutting edge mounting base 21 is a ring-shaped structure that is interference-fitted with the base assembly part 12; the cutting edge blocks 22 are strip-shaped structures with the same length as the cutting edge mounting base 21; multiple cutting edge blocks 22 are arranged around the outer circumferential surface of the cutting edge mounting base 21; along the machining rotation direction of the milling cutter, multiple diamond coating layers 3 are arranged one-to-one on the multiple cutting edge blocks 22.

[0050] It should be noted that, in the technical solution of the present invention, the diamond coating layer 3 is disposed on the radial side in front of the two circumferential surfaces of the cutting edge block 22 along the machining rotation direction.

[0051] The advantages of adopting the above-mentioned preferred solution are: along the machining rotation direction of the milling cutter, setting a single layer of diamond coating on the cutting edge block is beneficial to forming multiple diamond grinding edges on the outer periphery of the milling cutter. Each diamond coating in the working area of ​​the milling cutter has at most one diamond working at each point along the axial direction, which effectively avoids the circumferential blockage of dust between diamonds and makes the chip removal easy and fast.

[0052] Preferably, the circumferential length of each point in the diamond coating layer 3 along the axis is positively related to the radial length of the cutting edge block 22.

[0053] It should be noted that in the technical solution of the present invention, since multiple diamond coating layers 3 are correspondingly disposed on multiple cutting edge blocks 22 along the machining rotation direction of the milling cutter, and multiple cutting edge blocks 22 are wrapped around the outer peripheral surface of the cutting edge mounting base 21, from a macroscopic perspective, the working ring base 2 is a ring structure with multiple cutting edge blocks 22 wrapped around its outer peripheral surface. When the radial length of the cutting edge blocks 22 gradually increases, that is, the diameter of this ring structure gradually increases, the circumferential length of each point of the diamond coating layer 3 in the axial direction also gradually increases, and the number of diamond particles disposed on the diamond coating layer 3 will also gradually increase.

[0054] Special note: The circumferential length of the diamond coating layer 3 does not refer to the circumferential thickness of the diamond coating layer 3.

[0055] The beneficial effect of adopting the above-mentioned preferred scheme is that it helps the working ring substrate to play a role in resisting deformation, thereby improving the milling cutter's resistance to deformation during the machining process.

[0056] Preferred, such as Figure 8 As shown, the inlet baffle 4 is an annular structure, and the area between the inner wall of the inlet baffle 4 and the outer wall of the base assembly 12 is an annular inlet 7. The annular inlet 7 is a trumpet-shaped structure with the small diameter end close to the base handle 11.

[0057] The advantages of adopting the above preferred scheme are: the cooling water enters the funnel-shaped annular outer water inlet, which is conducive to smoothly entering the working ring substrate under the action of centrifugal force and tilt angle, so as to achieve internal cooling of the working ring substrate.

[0058] Preferred, such as Figure 4 and Figure 9 As shown, the blade mounting base 21 is provided with a plurality of water-passing and water-retaining grooves 23 in the circumferential direction. The water-passing and water-retaining groove 23 is a funnel-shaped structure with the small diameter end close to the annular water inlet 7. The water-passing and water-retaining groove 23 is an axial through hole connected to the annular water inlet 7. A single water-passing and water-retaining groove 23 is provided between two adjacent blade blocks 22.

[0059] The advantages of adopting the above-mentioned preferred solution are: the funnel-shaped water storage tank facilitates the smooth flow of cooling water from the inlet to the end of the milling cutter, thereby enabling the entire milling cutter to be cooled axially.

[0060] Preferred, such as Figure 3 As shown, the number of water storage tanks 23 is the same as the number of diamond coating layers 3, and the axial length of the water storage tanks 23 is equal to the axial length of the diamond coating layers 3.

[0061] The advantages of adopting the above-mentioned preferred scheme are that it helps to ensure that the diamond coating layer along the axial direction can be cooled, thereby improving cooling efficiency and cooling effect.

[0062] Preferred, such as Figure 7 and Figure 9 As shown, the blade mounting base 21 is provided with a plurality of water outlets 24 in the circumferential direction. Each water outlet 24 is an axial through hole that connects the water storage tank 23 to the outer diameter of the blade mounting base 21. The plurality of water outlets 24 correspond one-to-one with the plurality of water storage tanks 23. Each water outlet 24 is provided between two adjacent blade blocks 22.

[0063] The beneficial effect of adopting the above preferred solution is that the water outlet is set as a through hole, which allows each diamond coating layer, i.e. the diamond grinding edge, to receive a continuous supply of cooling water.

[0064] Preferably, the ratio of the distance b from the water outlet 24 to the adjacent diamond coating layer 3 to the distance B between two adjacent cutting edge blocks 22 is greater than or equal to 0.5 and less than or equal to 1.

[0065] Among them, such as Figure 5 and Figure 7 As shown, since the multiple diamond coating layers 3 are arranged one-to-one on the multiple cutting edge blocks 22 along the machining rotation direction of the milling cutter, the diamond coating layers 3 are arranged on the same side of the cutting edge blocks 22. Therefore, b represents the distance from the water outlet 24 to the adjacent and closest diamond coating layer 3; B represents the distance between two adjacent sidewalls of two adjacent cutting edge blocks 22.

[0066] The advantages of adopting the above preferred solution are: a suitable circumferential position of the outlet can prevent all the cooling water from being discharged in the area near the inlet, resulting in no water or little water near the end of the milling cutter, and can make the cooling water evenly distributed in all points along the axis.

[0067] Preferably, the circumferential width H of the outlet 24 is less than 0.3 mm.

[0068] The advantages of adopting the above preferred scheme are: the circumferential width of the outlet is less than 0.3 mm, which is conducive to the axial and balanced distribution of cooling water.

[0069] The present invention has the following beneficial effects:

[0070] 1. No internal cooling structure is required in the equipment, reducing the requirements for the equipment;

[0071] 2. Functional structure that enables external water supply with a diameter of less than 25 mm to be converted into internal cooling mode;

[0072] 3. Achieve independent and sufficient internal cooling water supply for each grinding edge;

[0073] 4. There is no possibility of circumferential blockage between diamond particles and it is difficult for blockage to occur in the axial direction. The grinding resistance is small and the wear effect on the bond is small, which is conducive to improving the life of the milling cutter.

[0074] 5. It is beneficial for high-speed grinding;

[0075] 6. The dynamic structure around the working diamond particles makes it easy and quick to remove dust and prevents it from accumulating, which is beneficial for the selection of fine diamond particles and for high-quality processing with low surface roughness.
