Description

Technical Field

[0001] This utility model belongs to the technical field of cutting and processing devices, and particularly relates to a high-speed cutting and processing equipment for gradient silicon-aluminum alloy materials. Background Technology

[0002] A patent titled "Aluminum Alloy Material Cutting Machine" (application number CN202323587862.2) is disclosed in the existing Chinese patent database. This machine, belonging to the field of cutting machine technology, includes a main body with four sets of support columns fixedly connected to its bottom four corners. Two sets of fixed platforms are fixedly connected to the upper ends of the front and rear sides of the main body. A gantry frame is fixedly connected to the upper middle part of the main body, and a protective box is fixedly connected to the left end of the gantry frame. A motor is fixedly installed inside the protective box. This invention, through the combined action of the fixed platforms, sliding grooves, telescopic push rods, clamping plates, and sliders, can clamp and fix aluminum alloy materials, facilitating accurate subsequent cutting operations. The combined action of the motor, threaded rod, sliding rod, moving block, cylinder, and cutter facilitates accurate and stable cutting of the clamped aluminum alloy material. The combined action of the water pump, spray head, water collection tank, protective net, water collection box, and filter screen facilitates cooling of the cutting area during the cutting operation.

[0003] In existing technologies, gradient silicon-aluminum alloys, during centrifugal casting, typically have a high-silicon outer layer and a high-aluminum inner layer, distributed radially in a gradient pattern. During cutting, the high-silicon region has a high silicon content, resulting in a material hardness of HV 150-300, requiring the use of highly wear-resistant cutting tools. Conversely, the high-aluminum region has a high aluminum content, making it prone to tool sticking, necessitating the use of tools with a low coefficient of friction. Therefore, this paper aims to propose a high-speed cutting and processing equipment for gradient silicon-aluminum alloy materials, capable of quickly changing cutting tools to complete the cutting of gradient silicon-aluminum alloys.

[0017] The technical solution of this application will be further described below with reference to the accompanying drawings and embodiments.

[0018] like Figure 1-3 As shown, a high-speed cutting and processing equipment for gradient silicon-aluminum alloy material is provided, including a frame 1. A gradient silicon-aluminum alloy bar 2 to be cut is suspended and fixed on the worktable of the frame 1. A transverse moving mechanism 3 is provided on the top of the frame 1 directly above the worktable. A control box 4 is horizontally slidably connected to the transverse moving mechanism 3. A rotation control mechanism 5 is provided inside the control box 4. The output end of the rotation control mechanism 5 is connected to a cutting assembly 6. The cutting assembly 6 includes two sets of cutting blades 16 arranged in a mirror image. One set of cutting blades 16 is used to cut the high silicon region of the gradient silicon-aluminum alloy bar 2, and the other set of cutting blades 16 is used to cut the high aluminum region of the gradient silicon-aluminum alloy bar 2.

[0019] Specifically, the rotation control mechanism 5 includes a servo motor 7 installed on the inner wall of the control box 4. The output end of the servo motor 7 is connected to a pinion 8. A rotating shaft 9 is inserted through the bottom of the control box 4. A large gear 10 is connected to the upper end of the rotating shaft 9. The large gear 10 meshes with the pinion 8. The lower end of the rotating shaft 9, which passes through the outside of the control box 4, is connected to the cutting assembly 6.

[0020] Specifically, the cutting assembly 6 includes a rotating plate 11 fixedly connected to the lower end of the rotating shaft 9. The rotating plate 11 can have a central hole and be fixedly connected to the rotating shaft 9 by a key connection. A set of horizontally spaced slide rails 12 are provided on both sides of the rotating plate 11. An inverted U-shaped plate 13 is vertically slidably connected on the two slide rails 12. A central shaft 14 is provided between the two ear plate sections of the U-shaped plate 13. A drive motor 15 is installed on the outer ear plate section of the U-shaped plate 13. The output end of the drive motor 15 is connected to the central shaft 14. The cutting blade 16 is sleeved on the central shaft 14 and rotates synchronously with the central shaft 14. A horizontal plate 17 is integrally welded to the surface of the rotating plate 11 located directly above the U-shaped plate 13. An electric cylinder 18 is installed on the upper surface of the horizontal plate 17. The piston rod shaft end of the electric cylinder 18 is connected to the upper surface of the middle section of the U-shaped plate 13.

[0021] Specifically, the lateral movement mechanism 3 includes a ball screw 19 mounted on the frame 1, a screw nut seat 20 connected to the ball screw 19, a reducer 21 for driving the ball screw 19 to rotate on the outside of the frame 1, and a connecting plate 22 integrally mounted on the top of the control box 4, which is bolted to the side of the screw nut seat 20.

[0022] Specifically, support seats 23 are horizontally spaced on the upper surface of the workbench of the frame 1. The upper surface of the support seat 23 has a semi-circular lower groove 24. The two ends of the gradient silicon-aluminum alloy bar 2 are placed in the lower groove 24. The upper end of the support seat 23 is connected to a pressure block 25. The lower surface of the pressure block 25 has an upper groove 26. The inner surface of the upper groove 26 abuts against the upper surface of the gradient silicon-aluminum alloy bar 2. A locking bolt 27 is inserted between the support seat 23 and the pressure block 25. The free end of the locking bolt 27 passing through the pressure block 25 is screwed into the support seat 23. A locking nut 28 is screwed onto the locking bolt 27 located above the pressure block 25. The locking nut 28 abuts against the upper surface of the pressure block 25.

[0023] Specifically, a horizontal guide rod 29 is provided on the frame 1, and a guide sleeve (not shown in the figure) is integrally provided on the outer surface of the control box 4. The guide sleeve is slidably connected to the guide rod 29. The cooperation between the guide rod 29 and the guide sleeve not only improves the stability of the control box 4 during horizontal movement, but also avoids the formation of large shear forces on the ball screw 19, which could lead to damage to the ball screw 19.

[0024] The operation of this utility model consists of the following steps:

[0025] 1. Determine the location of high-silicon and high-alumina regions: Mark the radial silicon content gradient range of the bar stock through metallographic analysis, hardness testing (HV>200 for high-silicon regions, HV<100 for high-alumina regions) or EDS composition scanning, such as high silicon in the outer layer and high aluminum in the inner layer.

[0026] 2. Clamping and fixing of the bar stock: The operator places both ends of the gradient silicon-aluminum alloy bar stock 2 to be cut into the lower grooves 24 of the two support seats 23, and connects the pressure block 25 to the support seat 23 through the locking bolts 27, so that the upper groove 26 of the pressure block 25 abuts against the upper surface of the bar stock, thus completing the positioning of the bar stock. If the bar stock is too long, a support can be added in the middle of the bar stock to prevent the cut surface from tilting due to its own weight during cutting.

[0027] 3. The cutting component 6 moves laterally. The operator controls the reducer 21 to work. The control box 4 moves horizontally through the screw transmission mechanism composed of the ball screw 19 and the screw nut seat 20, so as to realize the horizontal positioning of the control box 4 and the cutting component 6.

[0028] 4. During the bar cutting process, the electric cylinder 18 controls one of the cutting components 6 to move vertically downwards, first cutting the outer high-silicon region of the gradient silicon-aluminum alloy bar 2. When the feed reaches a certain depth, the electric cylinder 18 retracts the cutting component 6, and the drive motor 15 in the rotation control mechanism 5 operates. Through the cooperation of the pinion 8, the gear 10, and the rotating shaft 9, the rotating plate 11 rotates horizontally by 180°, switching to another cutting component 6. At this time, the vertical plane position of the cutting blade 16 in the cutting component 6 is consistent with that of the previous cutting blade 16. The electric cylinder 18 is controlled to cut the gradient silicon-aluminum alloy bar 2. The high-alumina zone inside the silicon-aluminum alloy bar 2 is cut. After the high-alumina zone is cut, the edge of the bar is finally cut by replacing the previous cutting blade 16. The cutting blade 16 can be a resin-bonded diamond wheel (suitable for the hard and brittle characteristics of the high-silicon zone) or a silicon carbide wheel (suitable for the toughness of the high-alumina zone). Both diamond wheels and silicon carbide wheels can cut the high-silicon and high-alumina zones. To ensure the anti-sticking requirement when cutting the high-alumina zone of the bar core, reduce the impact on the tool, and address the issue that aluminum chips tend to stick to the diamond wheel during high-alumina cutting, silicon carbide wheels are selected.
