Description

Technical Field

[0001] The invention relates to the field of aluminum alloy external cutting discs, in particular to a novel deformed aluminum alloy external cutting disc mechanism. Background Art

[0002] Aluminum alloy is an alloy material with aluminum as the main component and other elements (such as copper, zinc, magnesium, silicon, manganese, etc.) added. Aluminum alloy has the advantages of light weight, corrosion resistance, high strength and good processing performance. It is widely used in aerospace, automobile manufacturing, construction, electronics, shipbuilding, machinery and other fields.

[0003] As the penetration rate of aluminum alloy products in automobiles increases year by year, various components have increasingly stringent requirements for aluminum alloy quality. For example, in air suspension tanks, which withstand high pressure and maintain structural stability, the segregation layer on the surface of aluminum rods can cause serious defects in forged and extruded products, necessitating surface machining to remove the segregation layer. Currently, most factories use conventional lathes to perform surface machining on aluminum rods, a process that is complex, inefficient, and labor-intensive. Some factories also use a hot peeling process, which requires heating the aluminum rods to a certain temperature. Due to the high temperature sensitivity of the grain structure of deformed aluminum alloys, uncontrolled temperature during heating can easily lead to abnormal structures such as coarse grains, seriously compromising mechanical properties.

[0004] In summary, the above method wastes too much manpower and material resources in the process of external cutting of the aluminum alloy rod, and will damage the overall performance of the aluminum alloy rod, affecting the subsequent mechanical stability. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a new type of deformed aluminum alloy external cutting cutter disc mechanism to solve the technical problems that the above method wastes too much manpower and material resources in the process of external cutting of aluminum alloy rods, and will damage the overall performance of the aluminum alloy rods and affect the subsequent mechanical stability.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a novel deformed aluminum alloy external cutting tool disc mechanism, comprising a leading guide and a middle guide, wherein the leading guide and the middle guide are located in a processing chamber, and both the leading guide and the middle guide are provided with a through slot, wherein each of the through slots is provided with a plurality of conveying wheels, wherein the conveying wheels are adjustable, and a water baffle is provided on the leading guide at the through slot, wherein the water baffle is provided with a plurality of second cutting fluid outlets; A base is provided on the center guide at the through groove, and a cutter disc is rotatably provided in the base, wherein an array of turning components is detachably provided on the cutter disc, a T-shaped slide groove cooperating with the turning component is provided on the cutter disc, and a first cutting fluid outlet is provided on one side of the turning component on the cutter disc.

[0007] By adopting the above technical solution, multiple groups of tools are turned simultaneously under the action of the cutter disc, reducing the cutting stress of a single cutter head. At the same time, a first cutting fluid outlet is provided on the cutter disc at the tool position. During turning processing, the cutting fluid is sprayed out to quickly wash away the aluminum chips from the cutting edge, which significantly improves the stability of the cutter disc and the durability of the tool. When the cutting fluid directly cools the tool, the cutting fluid is sprayed out through the second cutting fluid outlet, and the cutting fluid is controlled in the processing room by a counter-flow method, thereby improving the cooling effect. By spraying coolant on both sides, aluminum chips are prevented from following the bar into the leading conveying area.

[0008] The present invention is further configured such that the turning assembly includes a tool handle, a tool box and a tool, the bottom of the tool handle is T-shaped and matched with a T-shaped slide groove, and the tool handle, tool box and tool are detachably configured.

[0009] Preferably, during installation, the tool handle is slid into the T-shaped slot of the cutter disc, and then the tool box is inserted, and the tool is inserted into the tool box, and is limited and fixed by a bolt assembly to ensure the stability of the tool during the turning process.

[0010] The present invention is further configured such that the inner wall of the base is arranged in a frustum shape, and the end of the handle is arranged in an inclined manner.

[0011] Preferably, when the cutter disc slides inwards by the action of a micro-control motor, it contacts the inner wall of the base, causing multiple sets of tool handles to slide forward a corresponding distance at the same time, so that all tool edges are at the same distance from the center, thereby achieving automatic tool adjustment.

[0012] The present invention is further configured such that a special-shaped slide groove is provided on the T-shaped slide groove, wherein the tool handle is elastically arranged in the T-shaped slide groove, and a guide column is insertably arranged at the bottom of the tool handle, and a limit rod cooperating with the guide column is provided in a pin-like manner on one side of the tool.

[0013] Preferably, during the process of the cutter disc sliding into the base, the guide post at the bottom of the tool handle slides toward the top of the special-shaped slide groove, so that during the process of the guide post sliding up, it will be inserted into the guide post hole. At this time, the limit rod is tightly attached to the outer wall of the tool. At the same time, when the tool is subsequently replaced, the cutter disc is moved to a position close to the leading edge. Under the action of the elastic component, the tool handle moves toward the outer wall of the cutter disc. At this time, the guide post will slide toward the bottom of the special-shaped slide groove, thereby causing the guide post to slide out of the guide post hole of the limit rod.

[0014] The present invention is further configured such that the knife handle, knife box and knife are all provided with jacks that cooperate with the limit rod, while both ends of the guide post are arranged in an arc shape, and the limit rod is provided with a guide post hole that cooperates with the top end of the guide post.

[0015] Preferably, the limit rod is inserted in the normal state, and the guide post hole opened on its outer wall is staggered with the guide post in the vertical state. In the process of the guide post moving upward through the special-shaped slide groove, the guide post will be inserted into the guide post hole, thereby causing the limit rod itself to move to one side. Since the outer diameter of one end of the limit rod is larger than its insertion hole, the tool can be stably limited to the tool handle in cooperation with the limit rod, thereby ensuring the rapid installation and disassembly of the tool.

[0016] The present invention is further configured such that a slider is symmetrically slidably provided on the side of the T-shaped slide groove, one side of the slider is connected to the tool handle, and the other side is connected to the elastic component.

[0017] Preferably, when the micro-control motor drives the cutter disc to move in the center guide direction, the tool handle will slide toward the center in cooperation with the base. During this process, the slider will be driven to squeeze its elastic component, causing the elastic component to be in a compressed state. Subsequently, when the tool needs to be replaced, the cutter disc is driven to move in the forward direction by the micro-control motor. During this process, under the resetting action of the elastic component, the tool handle moves away from the center position of the cutter disc.

[0018] The present invention is further configured such that an array of sensors is provided on a side of the center guide away from the base, wherein the sensors are electrically connected to the processing chamber.

[0019] Preferably, the sensor is a high-precision distance sensor, with four groups evenly arranged at right angles. It can measure and calculate the diameter and roundness of the aluminum rod in real time. When the product diameter has a specification deviation of 0.1mm or the two sets of diameter data in the vertical direction have a difference of 0.05mm, the cutter disc program automatically adjusts the tool to ensure the diameter accuracy of the aluminum rod and avoid the abnormal roundness of the rod from becoming elliptical.

[0020] The present invention is further configured such that the first cutting fluid outlet is located on the cutter disc and is arranged obliquely, with the inclined outlet facing the outer wall of the cutter.

[0021] Preferably, the inclined first cutting fluid outlet impacts the outer wall of the tool as soon as the cutting fluid is discharged, which can greatly improve the cooling effect, avoid tool sticking, and quickly flush aluminum chips from the cutting edge of the tool.

[0022] The present invention is further configured such that the outer wall of the water baffle is smooth, and the water baffle itself is located in the through groove and is replaceable.

[0023] Preferably, when aluminum chips are impacted by cutting fluid onto the outer wall of the water retaining plate, the aluminum chips can slide downward on the water retaining plate under the action of their own gravity, thereby effectively preventing the accumulation of aluminum chips on the water retaining plate.

[0024] The present invention is further configured such that the limiting rod is located on the outer surface of the cutter disc during installation and does not contact the cutter disc.

[0025] As a preferred embodiment, when subsequent staff replace the tool, it is convenient to directly pull out the limit rod to prevent multiple groups of limit rods from being blocked at the center position, thereby improving the overall replacement efficiency.

[0026] In summary, the present invention mainly has the following beneficial effects: The present invention allows an aluminum rod to pass through the through slots of the leading and middle guides. During the process of the cutter head rotating to cut the aluminum rod, multiple sets of cutters are turned simultaneously under the action of the cutter head, thereby reducing the cutting stress of a single cutter head and ensuring consistent performance of the cutter head. At the same time, a first cutting fluid outlet is provided on the cutter head at the cutter head. During turning, the cutter head can be cooled in real time from multiple directions through the first cutting fluid outlet, thereby improving the cooling effect and avoiding the problem of tool sticking. In addition, when the cutting fluid is sprayed out, aluminum chips are quickly washed away from the cutting edge, thereby significantly improving the stability of the cutter head and the durability of the cutter head. The present invention provides a water baffle in the leading through groove, and the water baffle in the leading guide is used to prevent the cutting fluid from flowing out of the through groove. Since a second cutting fluid outlet is provided on the water baffle, when the cutting fluid directly cools the tool, the cutting fluid is sprayed out through the second cutting fluid outlet, and the cutting fluid is controlled in the processing chamber by a counter-flow method, so that the closed processing space is filled with cutting fluid. On the one hand, the contact area between the coolant and the tool holder is increased, and the cooling effect is improved. On the other hand, the coolant is sprayed on both sides to prevent aluminum chips from following the bar into the conveying area of the leading guide, which may cause damage to the conveying wheel. The present invention provides a frustum-shaped slideway on the inner wall of the base. Since the ends of the tool handles are arranged at an angle, when the cutter disc slides inwards under the action of a micro-control motor, the tool handles come into contact with the inner wall of the base, causing multiple sets of tool handles to slide forward simultaneously by a corresponding distance, ensuring that all tool edges are at the same distance from the center, thereby achieving automatic tool adjustment. The present invention provides a special-shaped slide groove in the T-shaped slide groove of the cutter disc, and the special-shaped slide groove itself is set in a steep slope from low to high. During the process of the cutter disc sliding into the base, the guide post at the bottom of the knife handle slides toward the top of the special-shaped slide groove. Since the guide post and the guide post hole on the limit rod are staggered, the guide post will be inserted into the guide post hole during the process of sliding up. At this time, the limit rod is tightly attached to the outer wall of the tool, thereby realizing automatic clamping of the tool. At the same time, when the tool is subsequently replaced, the cutter disc is moved outward, and the tool handle is moved toward the outer wall of the cutter disc under the action of the elastic component. At this time, the guide post will slide toward the bottom of the special-shaped slide groove, thereby causing the guide post to slide out of the guide post hole of the limit rod, thereby releasing the limit on the tool. In this process, the tool can be quickly disassembled and installed, thereby improving working efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be understood as limiting the present invention.

[0030] The following describes an embodiment of the present invention based on its overall structure. Example 1

[0031] See also Figures 1-8The present invention discloses a novel deformed aluminum alloy external cutting cutter disc mechanism, comprising a leading guide 1, a middle guide 2, a conveying wheel 5, an adjusting mechanism, a turning mechanism and a cooling mechanism, wherein the leading guide 1 and the middle guide 2 are both located inside a processing chamber, and a through slot 3 is provided in the leading guide 1 and the middle guide 2, and a conveying wheel 5 is provided in the through slot 3. The conveying wheel 5 is driven to move toward the center position by a micro-control motor so as to be suitable for the outer diameter of the aluminum rod to be processed, thereby ensuring the clamping force on the aluminum rod and avoiding the slipping between the conveying wheel 5 and the surface of the aluminum rod due to insufficient clamping force. In addition, a base 8 is provided on the middle guide 2 at the through slot 3, and a cutter disc 6 is rotatably provided in the base 8. Five groups of turning assemblies are provided on the cutter disc 6, which are distributed at 72° around the center of the cutter disc 6. The outer wall of the aluminum rod is processed by the turning assembly driven by the rotation of the cutter disc 6, thereby reducing the cutting stress of a single cutter head and ensuring the consistent performance of the tool. The turning assembly includes a tool handle 10, a tool box 11 and a tool 9. The bottom of the tool handle 10 is T-shaped and matched with a T-shaped slot 14. During installation, the tool handle 10 is slid into the T-shaped slot 14 of the cutter disc, and then the tool box 11 is inserted, and the tool 9 is inserted into the tool box 11, and is fixed by a bolt assembly to ensure the stability of the tool during the turning process. Since the inner wall of the base 8 is frustum-shaped and the end of the tool handle 10 is inclined, when the cutter disc 6 slides inwardly through the action of the micro-control motor, the end of the tool handle 10 contacts the inner wall of the base 8, so that multiple groups of tool handles 10 slide forward a corresponding distance at the same time, so that the cutting edges of all tools 9 are at the same distance from the center, thereby realizing automatic tool adjustment; Then the aluminum rod is transported to one side for turning by the conveying wheel 5. At the same time, a first cutting fluid outlet 7 is provided on the cutter head 6 on one side of the turning assembly. During the processing, the tool 9 can be cooled in real time from multiple directions through the first cutting fluid outlet 7, thereby improving the cooling effect and avoiding the tool sticking phenomenon. In addition, the aluminum chips can be quickly washed away from the cutting edge during the flushing process, thereby increasing the life of a single cutting edge from 5000 kg of aluminum chips to 7500 kg of aluminum chips, thereby increasing its performance by 50% and extending the overall service life. In addition, a water baffle 12 is provided on the guide 1 at the through groove 3. The water baffle 12 is provided with an array of second cutting fluid outlets 13. When the cutting fluid directly cools the tool 9, the cutting fluid is sprayed out through the second cutting fluid outlet 13, and the cutting fluid is controlled in the processing chamber by a counter-flow method, so that the closed processing space is filled with cutting fluid. On the one hand, the contact area between the coolant, the tool holder 10 and the tool 9 is increased, and the cooling effect is improved, avoiding the tool sticking due to overheating of the cutting edge or adhesion of aluminum chips, which affects the tool life. On the other hand, by spraying coolant on both sides, aluminum chips are prevented from following the bar into the through groove 3 of the leader 1, which may cause damage to the conveying wheel 5.

[0032] In the above embodiment, please refer to Figure 1 and Figure 4 An array of sensors 4 is provided on the side of the center guide 2 away from the base 8. The sensors 4 are electrically connected to the processing chamber. The sensors 4 are high-precision distance sensors with four groups evenly arranged at right angles. They can measure and calculate the diameter and roundness of the aluminum bar in real time. When the product diameter has a 0.1mm specification deviation or the two sets of diameter data in the vertical direction have a 0.05mm difference, the cutter head program automatically adjusts the tool to ensure the diameter accuracy of the aluminum bar and avoid the abnormal roundness of the bar becoming elliptical. Example 2

[0033] See also Figures 9-13 A novel deformed aluminum alloy external cutting tool disc mechanism is shown, and its overall structure is similar to that of the first embodiment, wherein a special-shaped slide groove 18 is provided on the T-shaped slide groove 14, wherein the tool handle 10 is elastically arranged in the T-shaped slide groove 14, and a guide column 20 is insertably provided at the bottom of the tool handle 10, and a limit rod 15 is provided on one side of the tool 9 in a latch-type manner to cooperate with the guide column 20, and the special-shaped slide groove 18 is arranged in a steep slope from low to high. When the tool disc 6 slides into the base, the guide column 20 at the bottom of the tool handle 10 slides toward the top of the special-shaped slide groove 18. Under normal conditions, the limit rod 15 inserted has a guide column hole 21 provided on its outer wall and is staggered with the guide column 20 in a vertical state. The guide post 20 will slide toward the bottom of the special-shaped slot 18, thereby causing the guide post 20 to slide out of the guide post hole 21 of the limit rod 15. At this time, the staff can directly pull out the limit rod 15, which is convenient for disassembly and replacement of the tool 9.

[0034] In the above embodiment, please refer to Figure 9 and Figure 10, wherein a slider 16 is symmetrically provided on the side of the T-shaped slide 14, one side of the slider 16 is connected to the tool handle 10, and the other side is connected to the elastic component 17. When the micro-control motor drives the cutter disc 6 to move toward the center guide 2, the tool handle 10 will slide toward the center in cooperation with the base 8. In this process, the slider 16 is driven to squeeze its elastic component 17, so that the elastic component 17 is in a compressed state. Subsequently, when the tool needs to be replaced, the cutter disc 6 is driven by the micro-control motor to move in the direction of the front guide 1. In this process, under the resetting action of the elastic component 17, the tool handle 10 moves away from the center position of the cutter disc 6, which is convenient for subsequently driving the tool handle 10 to be displaced in the T-shaped slide 14.

[0035] The present invention works specifically as follows: when in use, the cutter disc in the middle guide 2 is pushed forward in the base 8, and a frustum-shaped slide is provided on the inner wall of the base 8. Since the ends of the tool handles 10 are inclined, they contact the inner wall of the base 8, so that multiple sets of tool handles 10 slide forward a corresponding distance at the same time, so that all tool edges are at the same distance from the center, thereby realizing automatic tool adjustment. The micro-control motor drives the conveying wheel 5 in the through slot 3 to move to the center position so that it is suitable for the outer diameter of the aluminum rod to be processed. Subsequently, the design of the five sets of conveying wheels 5 ensures the clamping force of the aluminum rod, and at the same time, the aluminum rod is conveyed to one side through the conveying wheel 5. The cutter head 6 drives the five groups of cutting tools 9 to rotate rapidly, reducing the cutting stress of a single cutting head. At the same time, a first cutting fluid outlet 7 is provided on the cutter head 6 on one side of the cutting tool 9. During the turning process, the cutting tool 9 can be cooled in real time from multiple directions at the same time through the first cutting fluid outlet 7, thereby improving the cooling effect and avoiding the phenomenon of tool sticking. When the cutting fluid is sprayed, the aluminum chips are quickly washed away from the cutting edge, which significantly improves the stability of the cutter head 6 and the durability of the cutting tool 9. In addition, a water baffle 12 is provided on the inner side of the through groove 3 on the leading edge 1, wherein a second cutting fluid outlet 13 is provided on the water baffle 12, and the cutting fluid is sprayed through the second cutting fluid outlet 13. The cutting fluid is controlled in the processing room by a hedging method, so that the closed processing space is filled with cutting fluid. On the one hand, the contact area between the coolant and the tool holder 10 and the cutting tool 9 is increased, thereby improving the cooling effect. On the other hand, by spraying coolant on both sides, aluminum chips are prevented from following the bar into the through groove 3 of the leading edge 1.

[0036] Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiment without creative contribution as needed without departing from the principles and purpose of the present invention. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
