Description

Technical Field

[0001] The present invention relates to the field of mechanical processing, in particular to a high-hardness wear-resistant milling device and a milling method for metal cutting processing. Background Art

[0002] The bed of high-hardness, wear-resistant milling equipment is typically constructed from high-quality gray cast iron (such as HT300). This material offers excellent shock absorption and stability, effectively reducing vibration during milling and providing a stable foundation for high-precision machining. The bed's structural design ensures sufficient rigidity to withstand the cutting forces generated when milling high-hardness materials.

[0003] The patent application with application number CN202411195041.0 discloses an automatic milling processing equipment and process for mold steel, including a lower clamping unit, an upper clamping unit installed on the outside of the lower clamping unit through a connecting frame, and a double-head milling unit installed on the left and right sides of the upper end of the lower clamping unit. The present invention can perform side milling processing on mold steels with different structures and accurately position them.

[0004] However, this patent also has the following shortcomings. When the currently used milling equipment is used to mill metal parts, cutting heat will be left on the surface of the metal parts due to milling. Cutting metal parts at too high a frequency will cause excessive heat to accumulate on the surface of the milling equipment. After the milling equipment is cooled, the residual stress on its surface may exceed the yield strength of the material, causing cracks, thereby reducing the wear resistance of the milling equipment. In response to this situation, a high-hardness and wear-resistant milling equipment and milling method for metal cutting are specially proposed. Summary of the Invention

[0005] The object of the present invention is to provide a high-hardness and wear-resistant milling equipment and a milling method for metal cutting to solve the problems raised in the above background technology.

[0011] According to the above technical solution, an adsorption hole is provided on the top of the fixing ring, and the top of the fixing ring has an adsorption effect. When the volume of the metal part is larger, the contact surface with the fixing ring is also larger.

[0012] According to the above technical solution, the covering film is made of a film material, a cavity is provided inside the covering film, and the covering film has a stretchable property, and the generated heat will be absorbed by the covering film.

[0015] According to the above technical solution, an absorption groove is provided on the surface of the absorption ring, and a cavity is provided inside the buffer rod, so that the heat absorbed in the absorption ring is transferred into the interior of the mounting ring.

[0017] A milling method for metal cutting comprises the following steps:

[0018] S1: Place the metal part on the surface of the slide, push the movable box by pulling the push frame, and then press the fixing ring with the metal part. The sliding arm will expand and contract inside the coating film to generate air pressure that will be sprayed into the coating film. The air pressure will cause the coating film to expand and contract outward and flip outward to the surface of the metal part to cover and fix it.

[0019] S2: Heat is absorbed by the covering film, and the metal parts squeeze the telescopic rod, causing it to expand and contract inward and vibrate. When the inside of the vibration membrane is under pressure, negative pressure suction is generated, which is transferred through the inside of the telescopic rod to the inside of the covering film, thereby absorbing the heat absorbed by the inside of the covering film into the inside of the vibration membrane, and finally dissipating the heat outward through the discharge holes on the surface of the vibration membrane.

[0020] S3: Start the telescopic device inside the fixed frame, thereby driving the telescopic platform to slide on the inner wall of the fixed frame, and then start the telescopic device inside the movable disk, thereby driving the mounting arm to slide left and right on the inner wall of the movable disk. When the mounting arm slides, it will drive the grinding block to cut the surface of the metal part, causing the absorption block to shrink inward due to vibration to generate suction. When the coolant inside the cooling box is absorbed into the injection tube through the telescopic ring, the coolant can be discharged into the cutting disk through the injection tube.

[0021] S4: Start the telescopic device in the telescopic table to slide inside the fixed frame. When the telescopic table drives the mounting plate to move to the surface of the metal part, start the three-phase motor inside the coating block to drive the punching rod to rotate on the inner wall of the mounting plate. Then start the telescopic arm to extend outward, thereby driving the cutting edge to move outward to cut the metal part. When the punching rod extends inward, it generates air pressure and discharges it into the telescopic plate. When the inside of the telescopic plate is pushed by the air pressure, the coolant inside the coating block will be sprayed from the inside of the buffer cavity to the surface of the cutting edge.

[0022] S5: By starting the miniature motor inside the absorption ring, the grinding column can be driven to rotate and cut the surface of the metal part. The heat generated when the grinding column cuts the metal part will be transferred into the absorption ring through the buffer rod. The heat absorbed by the absorption ring is transferred into the mounting ring. The absorbed heat can be evaporated into gas through the coolant inside the covering block.

[0023] Compared with the prior art, the present invention provides a high-hardness and wear-resistant milling equipment and milling method for metal cutting, which has the following beneficial effects:

[0024] 1. The present invention is provided with a support mechanism. When the sliding arm slides downward, it will drive the mounting column to expand and contract inside the covering film. The expansion and contraction of the sliding arm inside the covering film will generate air pressure that will be sprayed into the covering film. The air pressure will cause the covering film to expand and contract outward. After the covering film is filled with air pressure, it will flip outward to the surface of the metal part. The covering film that expands outward can cover and fix metal parts of different specifications to ensure the stability of the metal parts when they are milled.

[0025] 2. The present invention is provided with a fixed component. When the inside of the vibration membrane is subjected to pressure, a pressure difference is formed with the outside, thereby generating negative pressure suction, and transmitting it to the inside of the covering membrane through the inside of the telescopic rod, thereby absorbing the heat absorbed by the inside of the covering membrane into the inside of the vibration membrane, and finally dissipating the heat outward through the discharge holes on the surface of the vibration membrane. By setting up this component, the heat generated by metal parts during milling can be absorbed, avoiding excessive heat concentration in the cutting area.

[0026] 3. The present invention is provided with a milling assembly. When the grinding block cuts the surface of a metal part, the heat generated during cutting can be transferred into the interior of the cutting disc through the slots on the surface of the grinding block. When the heat comes into contact with the coolant inside the cutting disc, the heat will be absorbed. By setting up this mechanism, the cutting heat generated when the grinding block cuts the surface of the metal part can be absorbed, thereby preventing the grinding block from overheating and generating micro cracks on the surface of the metal part.

[0027] 4. The present invention is provided with a connecting mechanism. When the inside of the telescopic disk is pushed by air pressure, the coolant inside the coating block will be sprayed out from the inside of the buffer cavity, and the sprayed coolant will be sprayed onto the surface of the cutting edge, thereby cooling the surface of the cutting edge to avoid micro cracks on the surface of the cutting edge due to overheating. By setting up this mechanism, when milling metal parts of different specifications, overheating on the surface of the tool can be avoided to cause cracks, thereby improving the wear resistance of the milling tool when cutting metal parts.

DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0038] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but are not to be construed as limiting the present invention.

[0039] In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0040] For example 1, please refer to Figure 1-Figure 3The present invention provides a technical solution: a high-hardness and wear-resistant milling equipment for metal cutting, comprising a base plate 1, a slide 2 fixedly connected to the top of the base plate 1, a fixed frame 3 fixedly connected to the top of the base plate 1, a support plate 4 fixedly connected to the top of the base plate 1, one end of the slide 2 fixedly connected to the surface of the support plate 4, a telescopic platform 5 slidably connected to the inner wall of the fixed frame 3 via a slider, a telescopic arm 6 fixedly connected to the surface of the telescopic platform 5, a support mechanism 7 provided on the inner wall of the slide 2, and further comprising:

[0041] The supporting mechanism 7 includes a movable box 701, which is slidably connected to the inner wall of the slide 2. The left side of the movable box 701 is fixedly connected to a pushing frame 702, and the right side of the movable box 701 is fixedly connected to a connecting frame 703. The inner wall of the connecting frame 703 is fixedly connected to a vibration membrane 705. First, place the metal part on the surface of the slide 2, and the surface of the metal part contacts the surface of the support plate 4. The movable box 701 is pushed by pulling the pushing frame 702, so that the movable box 701 slides on the inner wall of the slide 2 toward the surface of the support plate 4. When the movable box 701 moves to the surface of the metal part, the fixed ring 7045 will be adsorbed on the surface of the metal part.

[0042] The top of the sliding arm 7046 is fixedly connected to the inner wall of the compression chamber 7043, and the top of the sliding arm 7046 is fixedly connected to the inner wall of the compression chamber 7042. The pressure of the fixing ring 7045 generated by the metal part drives the sliding arm 7046 to slide downward on the inner wall of the compression chamber 7043. When the sliding arm 7046 slides downward, it drives the mounting post 7044 to expand and contract inside the covering film 7042. The expansion and contraction of the sliding arm 7046 inside the covering film 7042 will generate air pressure sprayed into the inside of the covering film 7042, and the air pressure will cause the covering film 7042 to expand and contract outward.

[0043] An adsorption hole is provided at the top of the fixing ring 7045, and the top of the fixing ring 7045 has an adsorption effect. When the volume of the metal part is larger, the contact surface with the fixing ring 7045 is also larger, thereby causing the sliding arm 7046 to extend and retract inside the covering film 7042 to have a longer extension and retraction distance, which will also make the inside of the covering film 7042 be squeezed harder, thereby generating more air pressure to flow into the inside of the covering film 7042, allowing the covering film 7042 to extend and retract to a larger range outward, and after the covering film 7042 is filled with air pressure, it will flip outward to the surface of the metal part. The covering film 7042 that expands outward can cover and fix metal parts of different specifications to ensure the stability of the metal part when being milled.

[0044] The covering film 7042 is made of a membrane material, and a cavity is opened inside the covering film 7042. The covering film 7042 has a telescopic property. At the same time, the covering film 7042 is made of a material that can absorb heat energy. When the covering film 7042 comes into contact with the surface of the metal part, the metal part will generate heat inside when it is milled. The generated heat will be absorbed by the covering film 7042. When the surface of the metal part is milled, it will squeeze the telescopic rod 7041, causing the telescopic rod 7041 to expand and contract inward and generate vibration, thereby generating pressure on the vibration membrane 705 inside the connecting frame 703. When the vibration membrane 70 When the interior is pressurized, a pressure difference is formed with the outside, thereby generating negative pressure suction, which is transferred to the inside of the covering film 7042 through the inside of the telescopic rod 7041, thereby absorbing the heat absorbed by the inside of the covering film 7042 into the inside of the vibration membrane 705, and finally dissipating the heat outward through the exhaust holes on the surface of the vibration membrane 705. When a metal part is milled, a large amount of cutting heat is generated during the milling process. This heat is mainly concentrated in the cutting area. In severe cases, it will cause micro cracks on the surface of the milling tool. The heat generated by the metal part during milling can be absorbed to prevent excessive heat from being concentrated in the cutting area.

[0045] Example 2: Based on Example 1, continue to refer to Figure 4-Figure 5 The cooling mechanism 8 includes a mounting block 801 fixedly connected to one end of the telescopic arm 6, a movable disk 802 fixedly connected to the surface of the mounting block 801, a cooling box 803 fixedly connected to the top of the movable disk 802, a telescopic ring 804 fixedly connected to the top of the cooling box 803, an injection tube 805 fixedly connected to the end of the telescopic ring 804 away from the cooling box 803, and an end of the injection tube 805 away from the cooling box 803 is slidably connected to the top slot of the movable disk 802, and the inner wall of the movable disk 802 is provided with a milling Cutting component 806, the surface of the mounting block 801 is provided with a connecting mechanism 9. When the metal part is fixed on the surface of the support plate 4, the telescopic device inside the fixing frame 3 is started, and the model of the telescopic device is a hydraulic telescopic device, thereby driving the telescopic platform 5 to slide on the inner wall of the fixing frame 3. When the telescopic platform 5 moves to the surface of the metal part on the inner wall of the fixing frame 3, the telescopic device inside the movable disk 802 is started, and the model of the telescopic device is a corrugated telescopic device, thereby driving the mounting arm 8061 to slide left and right on the inner wall of the movable disk 802.

[0046] The milling assembly 806 includes a mounting arm 8061 that is slidably connected to the inner wall of the movable disk 802. The end of the mounting arm 8061 away from the inner wall of the movable disk 802 is fixedly connected to the cutting disk 8063. When the mounting arm 8061 slides, it will drive the grinding block 8064 to cut the surface of the metal part. When the grinding block 8064 cuts the metal part, it will cause the surface of the cutting disk 8063 to vibrate, thereby causing the absorption blocks 8062 on both sides of the cutting disk 8063 to shrink inward due to the vibration. When the absorption block 8062 shrinks inward, negative pressure suction is generated, thereby transmitting the absorption force to the inside of the movable disk 802 through the internal cavity of the mounting arm 8061. After the coolant inside the cooling box 803 is absorbed into the injection tube 805 through the telescopic ring 804, the coolant can be discharged into the inside of the movable disk 802 through the injection tube 805, and the coolant in the movable disk 802 can be absorbed into the cutting disk 8063 through the absorption block 8062.

[0047] A grinding block 8064 is fixedly connected to the surface of the cutting disk 8063, and absorption blocks 8062 are fixedly connected to both sides of the cutting disk 8063. When the grinding block 8064 cuts the surface of the metal part, the heat generated during cutting can be transferred into the interior of the cutting disk 8063 through the slots on the surface of the grinding block 8064. When the heat comes into contact with the coolant inside the cutting disk 8063, the heat will be absorbed, and the cutting heat generated when the grinding block 8064 cuts the surface of the metal part can be absorbed, thereby preventing the grinding block 8064 from overheating and generating micro cracks on the surface of the metal part.

[0048] Example 3: Based on Example 2, continue to refer to Figure 6-Figure 8 The connecting mechanism 9 includes a connecting arm 901, one end of the connecting arm 901 is fixedly connected to the surface of the telescopic platform 5, and the end of the connecting arm 901 away from the telescopic platform 5 is fixedly connected to the covering block 902, and the top slot of the covering block 902 is slidably connected to the telescopic column 903. The surface of the covering block 902 is provided with a buffer assembly 905. When it is necessary to process the plane of a metal part of certain specifications, the telescopic platform 5 is first driven to slide inside the fixed frame 3 by starting the internal telescopic device of the fixed frame 3. When the telescopic platform 5 drives the mounting plate 9052 to move to the surface of the metal part, the three-phase motor inside the covering block 902 is started to drive the punching rod 9053 to rotate on the inner wall of the mounting plate 9052, and the telescopic arm 6 is started to drive it to extend and retract outward, thereby driving the cutting edge 9054 to slide outward to cut the metal part.

[0049] The buffer assembly 905 includes a mounting plate 9052, which is fixedly connected to the surface of the covering block 902. The surface of the mounting plate 9052 is fixedly connected to a spray chamber 9051. The top of the spray chamber 9051 is fixedly connected to a telescopic plate 9055. The surface of the telescopic plate 9055 is fixedly connected to a buffer chamber 9056. The inner wall of the telescopic plate 9055 is slidably connected to a push arm 9057. Since the cutting edge 9054 is usually large in diameter, the surface of the metal part can be cut at high speed and better processing surface quality can be obtained. When the cutting edge 9054 comes into contact with the surface of the metal part, it will compress one end of the punch rod 9053, causing the punch rod 9053 to expand and contract inward. While buffering the cutting edge 9054, it can also generate air pressure and discharge it into the telescopic disk 9055. The air pressure will drive the pushing arm 9057 on the surface of the telescopic disk 9055 to slide outward. At the same time, since the mounting block 801 is connected to the interior of the movable disk 802, the coolant can be discharged into the telescopic disk 9055 through the internal cavity of the connecting arm 901 through the mounting block 801. When the telescopic disk 9055 is pushed by the air pressure, the coolant inside the covering block 902 will be ejected from the inside of the buffer cavity 9056, and the ejected coolant will be sprayed onto the surface of the cutting edge 9054, thereby cooling the surface of the cutting edge 9054 and preventing the surface of the cutting edge 9054 from causing micro cracks due to overheating.

[0050] It also includes a grinding assembly 904, which includes a mounting ring 9041 rotatably connected to the surface of the telescopic column 903, a buffer rod 9042 fixedly connected to the surface of the mounting ring 9041, an absorption ring 9043 fixedly connected to the end of the buffer rod 9042 away from the mounting ring 9041, and a grinding column 9044 fixedly connected to the surface of the absorption ring 9043. Since the surface of the grinding column 9044 is covered with blades, the grinding column 9044 can be driven to rotate and cut the surface of the metal part by starting the miniature motor inside the absorption ring 9043. The cutting process is relatively smooth when gradually cutting in and out of the workpiece, which is suitable for processing planes with larger areas. The heat generated when the grinding column 9044 cuts the metal part will be transferred into the absorption ring 9043 through the buffer rod 9042.

[0051] An absorption groove is provided on the surface of the absorption ring 9043, and a cavity is provided inside the buffer rod 9042. Through the connection between the absorption ring 9043 and the telescopic column 903, the heat absorbed in the absorption ring 9043 can be transferred into the interior of the mounting ring 9041. The absorbed heat can be evaporated into gas by the coolant inside the covering block 902. When milling metal parts of different specifications, overheating on the surface of the tool can be avoided to cause cracks, thereby improving the wear resistance of the milling tool when cutting metal parts.

[0052] A milling method for metal cutting comprises the following steps:

[0053] S1: Place the metal part on the surface of the slide 2, push the movable box 701 by pulling the pushing frame 702, and then press the fixing ring 7045 through the metal part. The sliding arm 7046 will expand and contract inside the covering film 7042 to generate air pressure sprayed into the covering film 7042. The air pressure will cause the covering film 7042 to expand and contract outward and flip outward to the surface of the metal part to cover and fix it.

[0054] S2: Heat is absorbed by the covering film 7042, and the metal parts squeeze the telescopic rod 7041, causing the telescopic rod 7041 to expand and contract inward and generate vibrations. When the inside of the vibration membrane 705 is under pressure, negative pressure suction is generated, which is transferred from the inside of the telescopic rod 7041 to the inside of the covering film 7042, thereby absorbing the heat absorbed by the inside of the covering film 7042 into the inside of the vibration membrane 705, and finally dissipating the heat outward through the discharge holes on the surface of the vibration membrane 705.

[0055] S3: Start the telescopic device inside the fixed frame 3, thereby driving the telescopic platform 5 to slide on the inner wall of the fixed frame 3, and then start the telescopic device inside the movable disk 802, thereby driving the mounting arm 8061 to slide left and right on the inner wall of the movable disk 802. When the mounting arm 8061 slides, it will drive the grinding block 8064 to cut the surface of the metal part, causing the absorption block 8062 to shrink inward due to vibration and generate suction. When the coolant inside the cooling box 803 is absorbed into the injection tube 805 through the telescopic ring 804, the coolant can be discharged into the cutting disk 8063 through the injection tube 805.

[0056] S4: Start the telescopic device in the telescopic platform 5 to slide inside the fixed frame 3. When the telescopic platform 5 drives the mounting plate 9052 to move to the surface of the metal part, start the three-phase motor inside the coating block 902 to drive the punching rod 9053 to rotate on the inner wall of the mounting plate 9052. Then, start the telescopic arm 6 to extend and retract outward, thereby driving the cutting edge 9054 to move outward to cut the metal part. When the punching rod 9053 extends and retracts inward, air pressure is generated and discharged into the telescopic plate 9055. When the inside of the telescopic plate 9055 is pushed by the air pressure, the coolant inside the coating block 902 will be sprayed from the inside of the buffer cavity 9056 to the surface of the cutting edge 9054.

[0057] S5: By starting the miniature motor inside the absorption ring 9043, the grinding column 9044 can be driven to rotate and cut the surface of the metal part. The heat generated when the grinding column 9044 cuts the metal part will be transferred into the absorption ring 9043 through the buffer rod 9042.

6. A metal cutting method according to any one of claims 1 to 5, characterized in that: The following steps are involved: S1: Place the metal part on the surface of the slide (2), push the movable box (701) by pulling the push frame (702), and then press the fixing ring (7045) through the metal part. The sliding arm (7046) expands and contracts inside the coating film (7042) to generate air pressure that sprays into the coating film (7042). The air pressure causes the coating film (7042) to expand and contract outward and flip outward to the surface of the metal part to cover and fix it; S2: Heat is absorbed by the coating film (7042), and the metal part squeezes the telescopic rod (7041), causing the telescopic rod (7041) to expand and contract inward and generate vibration. When the vibration membrane (705) is subjected to pressure, a negative pressure suction force is generated, which is transferred from the inside of the telescopic rod (7041) to the inside of the coating film (7042), thereby absorbing the heat absorbed by the inside of the coating film (7042) into the inside of the vibration membrane (705), and finally dissipating the heat outward through the discharge holes on the surface of the vibration membrane (705); S3: Start the telescopic device inside the fixed frame (3), thereby driving the telescopic platform (5) to slide on the inner wall of the fixed frame (3), and then start the telescopic device inside the movable disk (802), thereby driving the mounting arm (8061) to slide left and right on the inner wall of the movable disk (802). When the mounting arm (8061) slides, it drives the grinding block (8064) to cut the surface of the metal part, so that the absorption block (8062) shrinks inward due to vibration to generate suction. When the coolant inside the cooling box (803) is absorbed into the injection tube (805) through the telescopic ring (804), the coolant can be discharged into the inside of the cutting disk (8063) through the injection tube (805); S4: Start the telescopic device in the telescopic table (5) to slide inside the fixed frame (3), when the telescopic table (5) drives the mounting plate (9052) to move to the surface of the metal part, then start the three-phase motor inside the coating block (902) to drive the punching rod (9053) to rotate on the inner wall of the mounting plate (9052), and then start the telescopic arm (6) to extend and retract outward, thereby driving the cutting edge (9054) to move outward to cut the metal part, when the punching rod (9053) extends and retracts inward, air pressure is generated and discharged into the telescopic plate (9055), when the inside of the telescopic plate (9055) is pushed by the air pressure, the coolant inside the coating block (902) is sprayed from the inside of the buffer chamber (9056) to the surface of the cutting edge (9054); S5: By starting the miniature motor inside the absorption ring (9043), the grinding column (9044) can be driven to rotate and cut the surface of the metal part. The heat generated by the grinding column (9044) when cutting the metal part is transferred into the absorption ring (9043) through the buffer rod (9042). The heat absorbed by the absorption ring (9043) is transferred into the mounting ring (9041). The absorbed heat can be evaporated into gas through the coolant inside the covering block (902).
