[0017] A milling method for metal cutting processing 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 spray 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 for coating and fixing.

[0019] S2: Heat is absorbed by the coating film, and the metal parts squeeze the telescopic rod, causing it to expand and contract inward and vibrate.

[0024] 1. The present invention is provided with a supporting mechanism. When the sliding arm slides downward, it will drive the mounting column to expand and contract inside the coating film. The expansion and contraction of the sliding arm inside the coating film will generate air pressure that will be sprayed into the coating film. The air pressure will cause the coating film to expand and contract outward. After the inside of the coating film is filled with air pressure, it will flip outward to the surface of the metal part.

[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 will be formed with the outside, thereby generating a negative pressure suction force, which is transmitted to the inside of the coating membrane through the inside of the telescopic rod, thereby absorbing the heat absorbed by the inside of the coating 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.

[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 disk through the slots on the surface of the grinding block. When the heat comes into contact with the coolant inside the cutting disk, the heat is 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 generating micro cracks on the surface of the metal part due to overheating when cutting the metal part.

[0027] 4. The present invention is provided with a connecting mechanism. When the inside of the telescopic disk is pushed by the 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.

DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present invention will be described clearly and completely 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, and should not be construed as limiting the present invention.

[0039] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] For example, see Figure 1-Figure 3The present invention provides a technical solution: a high-hardness wear-resistant milling equipment for metal cutting, comprising a bottom plate 1, a slide 2 is fixedly connected to the top of the bottom plate 1, a fixed frame 3 is fixedly connected to the top of the bottom plate 1, a support plate 4 is fixedly connected to the top of the bottom plate 1, one end of the slide 2 is fixedly connected to the surface of the support plate 4, the inner wall of the fixed frame 3 is slidably connected to a telescopic table 5 through a slider, a telescopic arm 6 is fixedly connected to the surface of the telescopic table 5, and a support mechanism 7 is arranged on the inner wall of the slide 2, and also includes:

[0041] The supporting mechanism 7 includes a movable box 701, which is slidably connected to the inner wall of the slide 2. A pushing frame 702 is fixedly connected to the left side of the movable box 701, and a connecting frame 703 is fixedly connected to the right side of the movable box 701. A vibration membrane 705 is fixedly connected to the inner wall of the connecting frame 703. First, a metal part is placed 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 from the inner wall of the slide 2 to the surface of the support plate 4. When the movable box 701 moves to the surface of the metal part, the fixing ring 7045 will be adsorbed on the surface of the metal part.

[0042] It also includes a fixing component 704, the fixing mechanism includes a telescopic rod 7041 fixedly connected to the inner wall of the connecting frame 703, the end of the telescopic rod 7041 away from the connecting frame 703 is fixedly connected to a coating film 7042, the surface of the coating film 7042 is fixedly connected to a compression chamber 7043, the inner wall of the compression chamber 7043 is slidably connected to a sliding arm 7046, one end of the sliding arm 7046 is slidably connected to the inner wall of the coating film 7042, and the top of the sliding arm 7046 is fixedly connected to a fixing ring 7045, and then the metal parts press the fixing ring 7045, thereby driving the sliding arm 7046 to slide downward on the inner wall of the compression chamber 7043. When the sliding arm 7046 slides downward, it will drive the mounting column 7044 to expand and contract into the coating film 7042. The expansion and contraction of the sliding arm 7046 in the coating film 7042 will generate air pressure that will be sprayed into the coating film 7042, and the air pressure will cause the coating film 7042 to expand and contract outward.

[0043] An adsorption hole is provided on 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 be able to extend and retract the distance inside the coating film 7042 longer, which will also make the inside of the coating film 7042 subject to stronger squeezing force, thereby generating more air pressure to flow into the coating film 7042, allowing the coating film 7042 to have a larger range of extension and retraction outwards. After the coating film 7042 is filled with air pressure, it will flip outwards to the surface of the metal part. The coating film 7042 that expands outwards can cover and fix metal parts of different specifications to ensure the stability of the metal parts when they are milled.

[0044] The coating film 7042 is made of a film material, and a cavity is formed inside the coating film 7042. The coating film 7042 has a telescopic property. At the same time, the coating film 7042 is made of a material that can absorb heat energy. When the coating film 7042 comes into contact with the surface of the metal part, the metal part will generate heat inside when it is milled, and the generated heat will be absorbed by the coating film 7042. When the surface of the metal part is milled, it will squeeze the telescopic rod 7041, causing the telescopic rod 7041 to telescope inward and vibrate, thereby generating pressure on the vibration film 705 inside the connecting frame 703. When the vibration film 70 When the inside is pressurized, a pressure difference is formed with the outside, thereby generating negative pressure suction, which is transmitted to the inside of the covering film 7042 through the inside of the telescopic rod 7041, so that the heat absorbed by the inside of the covering film 7042 is absorbed into the inside of the vibration film 705, and finally the heat is dissipated outward through the discharge holes on the surface of the vibration film 705. When the metal part is milling, a large amount of cutting heat is generated during the milling process, and this heat is mainly concentrated in the cutting area. In severe cases, micro cracks will be generated on the surface of the milling tool. The heat generated by the metal part during milling can be absorbed to avoid excessive heat 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 is fixedly connected to the surface of the mounting block 801, a cooling box 803 is fixedly connected to the top of the movable disk 802, a telescopic ring 804 is fixedly connected to the top of the cooling box 803, an injection tube 805 is fixedly connected to the end of the telescopic ring 804 away from the cooling box 803, and the 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 The cutting assembly 806 and the surface of the mounting block 801 are 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 fixed frame 3 is started, and the model of the telescopic device is a hydraulic telescopic device, thereby driving the telescopic table 5 to slide on the inner wall of the fixed frame 3. When the telescopic table 5 moves to the surface of the metal part on the inner wall of the fixed 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 which is slidably connected to the inner wall of the movable disk 802. The end of the mounting arm 8061 which is 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 is cutting the metal part, it will cause the surface of the cutting disk 8063 to vibrate, so that the absorption blocks 8062 on both sides of the cutting disk 8063 will shrink inward due to the vibration. When the absorption blocks 8062 shrink inward, negative pressure suction will be generated, so that the absorption force will be transmitted to the inside of the movable disk 802 through the internal cavity of the mounting arm 8061. When the coolant in 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 blocks 8062.

[0047] A grinding block 8064 is fixedly connected to the surface of the cutting disk 8063, and absorption blocks 8062 are fixedly connected on both sides of the cutting disk 8063. When the grinding block 8064 cuts the surface of a 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. 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 generating micro cracks on the surface of the metal part due to overheating when cutting 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 which 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 a covering block 902, and a telescopic column 903 is slidably connected to the top slot of the covering block 902. A buffer component 905 is provided on the surface of the covering block 902. 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 telescope 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 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, a spray chamber 9051 is fixedly connected to the surface of the mounting plate 9052, a telescopic plate 9055 is fixedly connected to the top of the spray chamber 9051, a buffer chamber 9056 is fixedly connected to the surface of the telescopic plate 9055, and a push arm 9057 is slidably connected to the inner wall of the telescopic plate 9055. Since the cutting edge 9054 is usually large in diameter, the surface of the metal part can be cut at high speed and a better processing surface quality can be obtained. When the cutting edge 9054 comes into contact with the surface of the metal part, one end of the punch rod 9053 is compressed, causing the punch rod 9053 to telescope 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 inside of the movable disk 802, the coolant can be discharged into the telescopic disk 9055 through the mounting block 801 through the internal cavity of the connecting arm 901. When the telescopic disk 9055 is pushed by the air pressure, the coolant inside the coating 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 to prevent the surface of the cutting edge 9054 from causing micro cracks due to overheating.

[0050] It also includes a grinding component 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 a larger plane. The heat generated by the grinding column 9044 when cutting 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. The heat absorbed in the absorption ring 9043 can be transferred into the mounting ring 9041 through the connection between the absorption ring 9043 and the telescopic column 903. The absorbed heat can be evaporated into gas through 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, so as to improve the wear resistance of the milling tool when cutting metal parts.

[0052] A milling method for metal cutting processing 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 coating film 7042 to generate air pressure that will be sprayed into the coating film 7042. The air pressure will cause the coating film 7042 to expand and contract outward and flip outward to the surface of the metal part for coating and fixing.

[0054] S2: Heat is absorbed by the coating film 7042, and the metal parts squeeze the telescopic rod 7041, causing the telescopic rod 7041 to expand and contract inward and vibrate. When the inside of the vibration membrane 705 is subjected to pressure, negative pressure suction 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.

[0055] S3: Start the telescopic device inside the fixed frame 3, thereby driving the telescopic table 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, 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 cutting disk 8063 through the injection tube 805.

[0056] 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, 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 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 by the grinding column 9044 when cutting the metal part will be 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.
