Description

Technical Field

[0001] The present invention belongs to the technical field of laser cladding, and particularly relates to a wide-spot intelligent laser cladding machine for rotary cutting tools. Background Art

[0002] With the development and progress of the national economy and the increasing market demand, the production and sales prospects of large flat tools such as rotary cutting tools are quite favorable. Compared with traditional blades, laser cladding blades comply with national industrial policies and industry development plans, and have broad sales space, good development prospects, and huge market potential in the domestic market.

[0003] However, the manufacturing of traditional rotary cutting tools is deeply troubled by double dilemmas of process and product performance. In terms of process, the heat treatment process of hot-rolled steel is complex, the long-term operation of high-temperature heating furnaces consumes a large amount of energy, cooling consumes a lot of water, and waste gas emissions cause serious pollution. The energy consumption for producing a single tool is astonishing. In terms of product performance, traditional tools have poor hardness, toughness, wear resistance, and impact resistance. They wear quickly and have a short lifespan during processing. Frequent tool changes drive up costs and reduce efficiency. When dealing with complex working conditions or special woods, they are prone to chipping, deformation, and falling off, and it is difficult to meet the diverse market demands. Therefore, laser cladding blades came into being. Through processing by a cladding machine set, tool production features energy conservation, environmental protection, and stability.

[0004] However, there are many problems during the startup process of the cladding machine set. First of all, the operation steps are cumbersome, and each device needs to be started separately depending on the control system, which greatly prolongs the overall startup time of the cladding machine set.

[0005] In today's production environment that pursues high efficiency and quick response, if the cladding machine cannot achieve one-key automated and intelligent startup operations, it will greatly weaken its advantages in market competition. When facing urgent production tasks or the need to quickly adjust the production state, the cladding machine cannot quickly enter the best working state, thus exposing obvious shortcomings in terms of quick response and high-efficiency operation.

[0006] In summary, we provide a wide-spot intelligent laser cladding machine for rotary cutting tools. Summary of the Invention

[0007] The purpose of the present invention is to provide a wide-spot intelligent laser cladding machine for rotary cutting tools, aiming to solve the problem in the prior art that in today's production environment that pursues high efficiency and quick response, if the cladding machine cannot achieve one-key automated and intelligent startup operations, it will greatly weaken its advantages in market competition. When facing urgent production tasks or the need to quickly adjust the production state, the cladding machine cannot quickly enter the best working state, thus exposing obvious shortcomings in terms of quick response and high-efficiency operation.

[0008] To achieve the above object, the present invention provides the following technical solutions: A rotary cutting tool wide-spot intelligent laser cladding machine, including a base, a working platform, a high-power wide-spot laser cladding device, a water chiller, a dust collector, a numerical control cabinet, and a power machine. A laser generator and an air dryer are provided at the back end of the working platform. Fixed plates of dust-proof bellows are installed at both ends of the working platform. The high-power wide-spot laser cladding device adopts a 60-mm wide-spot cladding component. Two slide rails are installed at the top of the base. A toothed plate is installed at the top of the base and located between the two slide rails. Sliders are installed at the bottom end of the working platform. A servo motor is installed in the inner cavity at the bottom end of the working platform. The output shaft of the servo motor is connected to a gear.

[0009] Preferably, for a rotary cutting tool wide-spot intelligent laser cladding machine of the present invention, the working platform is slidably connected to the base through the slide rails and the sliders, and the fixed plates of the dust-proof bellows are attached to the surfaces of the slide rails and the sliders.

[0010] Preferably, for a rotary cutting tool wide-spot intelligent laser cladding machine of the present invention, the gear meshes with the toothed plate, and the working platform is gear-linked to the base through the gear and the toothed plate.

[0011] Preferably, for a rotary cutting tool wide-spot intelligent laser cladding machine of the present invention, a baffle is provided at the front end of the working platform, and fixing blocks are installed on both sides of the front end face of the working platform.

[0012] Preferably, for a rotary cutting tool wide-spot intelligent laser cladding machine of the present invention, a lead screw is installed inside the fixing block. A bearing is installed at one end of the lead screw. A first motor is installed at the other end of the lead screw, and the first motor is assembled at the end of the fixing block. A nut sleeve is threadedly connected to the surface of the lead screw, and the outer side walls of the nut sleeve are connected to both ends of the baffle.

[0013] Preferably, for a rotary cutting tool wide-spot intelligent laser cladding machine of the present invention, the baffle is threadedly lifted and lowered with the lead screw through the nut sleeve.

[0014] Preferably, for a rotary cutting tool wide-spot intelligent laser cladding machine of the present invention, the lead screw is rotatably connected to the fixing block through the bearing and the first motor.

[0015] Preferably, for a rotary cutting tool wide-spot intelligent laser cladding machine of the present invention, a support plate and a fixing plate are installed at the top of the mounting seat of the numerical control cabinet. A guide rod is penetrated and sleeved on the surface of the support plate. The bottom end of a threaded rod is threadedly penetrated and connected to the surface of the fixing plate and is provided with a convex block. A rotation groove in a "convex" shape is opened at the top of the connection seat of the numerical control cabinet.

[0016] Preferably, as a rotary cutting tool wide-spot intelligent laser cladding machine of the present invention, the numerical control cabinet is connected to the mounting base in a lifting manner through a threaded rod, and the convex block is adaptively assembled inside the rotating groove.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: In the present invention, the rotary cutting tool to be clad is fixed on the working platform, and then the numerical control cabinet is operated to start the dust collector, power machine, water cooler and high-power wide-spot laser cladding equipment at the same time. During this process, the numerical control cabinet automatically controls the start and operation of each device with one key, greatly reducing the pre-preparation time. At the same time, the numerical control cabinet is connected to and controls the working platform, high-power wide-spot laser cladding equipment, water cooler, dust collector and power machine, facilitating the intelligent adjustment of the processing data parameters of the rotary cutting tool wide-spot intelligent laser cladding machine through the numerical control cabinet. Furthermore, the automation and intelligence of the rotary cutting tool wide-spot intelligent laser cladding machine are realized, enabling the rotary cutting tool wide-spot intelligent laser cladding machine to quickly enter the best working state when facing urgent production tasks or the need to quickly adjust the production state, thus significantly reducing the obvious shortcomings in terms of rapid response and efficient operation.

[0018] Then, the numerical control cabinet utilizes the cooperation of the threaded rod and the guide rod to flexibly adjust the height of the numerical control cabinet, meeting the needs of workers of different heights and significantly improving the convenience and comfort of operation. Subsequently, the working platform moves close to the high-power wide-spot laser cladding equipment on the base. During this process, through the dust-proof bellows fixing plate attached to the surface of the slide rail and in cooperation with the servo motor driving the gear to rotate and engage with the toothed plate, when the slider moves along the slide rail, the dust-proof bellows fixing plate can effectively remove the oxides on the surface of the slide rail. This avoids the wear of the slide rail caused by oxides and the resulting gaps, thereby ensuring the stability of the working platform, significantly improving the accuracy of the rotary cutting tool during the cladding process, and preventing the shaking of the working platform. Then, the high-power wide-spot laser cladding equipment performs cladding processing on the long plate. During this process, the baffle connected to the front end of the working platform rises to block the spark splash generated during the cladding process, avoiding the risk of scalding the skin of workers passing through the front end of the working platform where the spark splashes, and enhancing the safety of the working environment.

Detailed implementation manners

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment 1

[0022] Please refer to Figures 1-6 , the present invention provides the following technical solutions: A rotary cutter wide-spot intelligent laser cladding machine, including a base 1, a working platform 2, a high-power wide-spot laser cladding equipment 9, a water chiller 3, a dust collector 4, a numerical control cabinet 8 and a power machine 6. A laser generator 5 and an air dryer 7 are arranged at the back end of the working platform 2. Dust-proof bellows fixing plates 27 are installed at both ends of the working platform 2. The high-power wide-spot laser cladding equipment adopts a 60mm wide-spot cladding component. Two slide rails 10 are installed at the top end of the base 1, and a toothed plate 11 is installed at the top end of the base 1 and located between the two slide rails 10. A slider 12 is installed at the bottom end of the working platform 2, and a servo motor 13 is installed in the inner cavity at the bottom end of the working platform 2. The output shaft of the servo motor 13 is connected to a gear 14.

[0023] Preferably in the embodiment: The working platform 2 is slidably connected to the base 1 through the slide rail 10 and the slider 12, and the dust-proof bellows fixing plate 27 is attached to the surfaces of the slide rail 10 and the slider 12.

[0024] Preferably in the embodiment: The gear 14 meshes with the toothed plate 11, and the working platform 2 and the base 1 are connected by a gear linkage through the gear 14 and the toothed plate 11.

[0025] In the embodiment, first of all, the intelligent laser cladding machine with a wide spot of rotary cutting tool is composed of a base 1, a working platform 2, a high-power wide-spot laser cladding device 9, a water chiller 3, a dust collector 4, a numerical control cabinet 8, a power machine 6, a laser generator 5 and an air dryer 7. The working platform 2 is connected to the bottom end of the base 1, and the high-power wide-spot laser cladding device 9, the water chiller 3, the dust collector 4, the numerical control cabinet 8, the power machine 6, the laser generator 5 and the air dryer 7 are installed on one side of the base 1 and the working platform 2.

[0026] The water chiller 3 is mainly used to cool the laser generator 5.

[0027] The main purpose of the dust collector 4 is to suck away the splashes such as smoke, impurities, and sparks generated during the cladding process, and keep the working environment clean and hygienic.

[0028] The power machine 6 is a device that converts various forms of energy into mechanical energy and provides a power source for other mechanical devices.

[0029] The laser generator 5 is a device that generates a laser beam. It makes the excitation medium (such as gas, solid, liquid, etc.) undergo stimulated emission, thereby generating a laser beam with high energy, high directivity, and high monochromaticity.

[0030] The air dryer 7 is used to remove moisture in the air and reduce the humidity of the air.

[0031] Among them, the air outlet of the dust collector 4 is connected to the high-power wide-spot laser cladding device 9, and during operation, it sucks away the splashes such as smoke, impurities, and sparks generated during the cladding process.

[0032] In addition, when the working platform 2 moves on the base 1 close to the high-power wide-spot laser cladding device 9, the moving mechanism of the working platform 2 is as follows: After the servo motor 13 is started, it drives the gear 14 to rotate, and the gear 14 engages with the toothed plate 11 to move forward, thereby driving the working platform 2 to move forward along the top of the base 1. At the same time, the working platform 2 also causes the slider 12 to move on the slide rail 10. As the working platform 2 moves, the dust-proof bellows fixing plate 27 wipes the surface of the slide rail 10 accordingly, effectively removing the oxides on it. This design prevents the wear and gap generation of the slide rail 10 caused by oxides, ensures the stability of the working platform 2, significantly improves the accuracy of the rotary cutting tool in the cladding process, and avoids the shaking of the working platform 2. Embodiment Two

[0033] Please refer to Figures 1-6 , a baffle 15 is provided at the front end of the working platform 2, and fixing blocks 16 are installed on both sides of the front end face of the working platform 2.

[0034] Preferably in the embodiment: A lead screw 17 is installed inside the fixed block 16. One end of the lead screw 17 is installed with a bearing 18, and the other end of the lead screw 17 is installed with a first motor 19, and the first motor 19 is assembled at the end of the fixed block 16. A thread bush 20 is threadedly connected to the surface of the lead screw 17, and the outer side walls of the thread bush 20 are connected to both ends of the baffle 15.

[0035] Preferably in the embodiment: The baffle 15 forms a threaded lifting connection with the lead screw 17 through the thread bush 20.

[0036] Preferably in the embodiment: The lead screw 17 forms a rotational connection with the fixed block 16 through the bearing 18 and the first motor 19.

[0037] In the embodiment, as described in Embodiment 1, when the working platform 2 moves on the base 1 and processes near the bottom end of the high-power wide-spot laser cladding device 9, the baffle 15 can be raised to provide necessary shielding. The specific operation is as follows: Start the first motor 19, and its output shaft drives the lead screw 17 to rotate within the inner ring of the bearing 18. Subsequently, the thread bush 20 moves along the thread on the surface of the lead screw 17, and this movement drives the movement of the baffle 15, causing the baffle 15 to rise and block in front of the working platform 2. The main purpose of this design is to block the spark splash generated during the cladding process, thereby avoiding the risk of scalding the skin of the staff when passing by the front end of the working platform 2 due to the splashing sparks, greatly enhancing the safety of the working environment.

[0038] It should be noted that this shielding design is only for the front end of the working platform 2 because the staff usually only move in this area. The back end of the working platform 2 is arranged with important components such as the high-power wide-spot laser cladding device 9, the water chiller 3, the dust collector 4, the numerical control cabinet 8, the power machine 6, the laser generator 5, and the air dryer 7, so the staff will not walk through this area.

[0039] In addition, if it is necessary to shield the periphery of the working platform 2, it can be achieved by installing the corresponding baffle 15 on the outer side wall of the working platform 2. Such a design is both flexible and practical, and can be adjusted according to different processing requirements and working environments. Embodiment 3

[0040] Please refer to Figures 1-6 , a support plate 21 and a fixing plate 22 are installed at the top of the mounting seat of the numerical control cabinet 8. A guide rod 24 is penetrated and sleeved on the surface of the support plate 21, and a threaded rod 23 is penetrated and threadedly connected to the surface of the fixing plate 22.

[0041] Preferably in the embodiment: A convex block 26 is installed at the bottom end of the threaded rod 23, and a rotation groove 25 in the shape of a "convex" character is opened at the top end of the connection seat of the numerical control cabinet 8.

[0042] Preferably in the embodiment: The numerical control cabinet 8 is connected to the mounting seat in a lifting manner through the threaded rod 23, and the convex block 26 is adaptively assembled inside the rotating groove 25.

[0043] In the embodiment, according to what is described in Embodiment 1, when the numerical control cabinet 8 is used to start the high-power wide-spot laser cladding equipment 9 and the height of the numerical control cabinet 8 needs to be adjusted, by rotating the threaded rod 23, the convex block 26 can be driven to rotate in the rotating groove 25, so as to realize the rise or fall of the threaded rod 23 relative to the surface of the fixed plate 22. This movement process will synchronously drive the numerical control cabinet 8 to move up and down, thereby realizing the flexible adjustment of the height of the numerical control cabinet 8. Such a design significantly improves the convenience and comfort of operation, meeting the usage requirements of workers of different heights.

[0044] In order to further enhance the stability of the height adjustment of the numerical control cabinet 8, a guide rod 24 and a support plate 21 are also designed as auxiliary support structures. The guide rod 24 ensures the linear movement of the numerical control cabinet 8 during the height adjustment process, avoiding shaking or deviation. Such a design makes the height adjustment of the numerical control cabinet 8 more stable and reliable, providing a better usage experience for workers.

[0045] In summary, according to what is described in Embodiments 1 to 3, the working principle of cladding is as follows: Place the rotary cutting tool to be clad on the working platform and fix it. Then, the worker operates the numerical control cabinet 8 and starts the movement of the high-power wide-spot laser cladding equipment 9, the water chiller 3, the dust collector 4, and the power machine 6 at the same time. Then, the worker starts the laser generator 5 and the air dryer 7 to run. During this process, the numerical control cabinet 8 automatically controls the start and operation of each device with one key, greatly reducing the pre-preparation time. At the same time, the connection control between the numerical control cabinet 8 and the high-power wide-spot laser cladding equipment 9, the water chiller 3, the dust collector 4, and the power machine 6 facilitates the intelligent adjustment of the processing data parameters of the rotary cutting tool wide-spot intelligent laser cladding machine through the numerical control cabinet 8. Furthermore, the automation and intelligent operation of the rotary cutting tool wide-spot intelligent laser cladding machine are realized, enabling the rotary cutting tool wide-spot intelligent laser cladding machine to quickly enter the best working state when facing urgent production tasks or when rapid adjustment of the production state is required, thus significantly reducing the obvious shortcomings in terms of rapid response and efficient operation. At the same time, when producing tools, it also has the characteristics of energy saving, environmental protection, and stability.

[0046] Next, referring to Embodiment 3, the numerical control cabinet 8 realizes the flexible adjustment of the height of the numerical control cabinet 8 by the cooperation of the threaded rod 23 and the guide rod 24, meeting the needs of workers of different heights and significantly improving the convenience and comfort of operation.

[0047] Subsequently, the intelligent laser cladding machine with a wide spot of the rotary cutting tool is started by using the numerical control cabinet 8. The working platform 2 drives the rotary cutting tool to approach the bottom end of the high-power wide-spot laser cladding device 9 under the movement of the base 1. The movement mechanism of the working platform 2 refers to the first embodiment. During this process, through the dust-proof bellows fixing plate 27 attached to the surface of the slide rail 10 and in cooperation with the servo motor 13 driving the gear 14 to rotate and engage with the toothed plate 11, when the slider 12 moves along the slide rail 10, the dust-proof bellows fixing plate 27 can effectively remove the oxides on the surface of the slide rail 10. This avoids the wear of the slide rail 10 caused by oxides and the resulting gaps, thereby ensuring the stability of the working platform 2, significantly improving the accuracy of the rotary cutting tool during the cladding process, and preventing the shaking of the working platform 2. Next, a special powder alloy material with patented technology is used. The powder alloy material is loaded into the powder loading container connected to the high-power wide-spot laser cladding device 9. Then, the high-power wide-spot laser cladding device 9 performs cladding processing on the rotary cutting tool. The powder alloy material in the container is sent to the tool body through the powder feeding pipeline, and then the high-power wide-spot laser cladding device 9 clads the powder alloy material on the tool body to act as the cutting edge part, making the rotary cutting tool processed by the intelligent laser cladding machine with a wide spot of the rotary cutting tool have higher hardness, toughness, and wear resistance. And during the production process, pads are placed at the starting and ending positions of the sheet material cladding fixed on the working platform 2 to ensure sufficient supply of metal powder at the edge of the sheet material cladding, good molten pool shape, and sufficient cladding height. Subsequently, the worker observes the traveling position of the laser cladding molten pool. When its position is close to the end point of the sheet material, preparations for ending need to be made. The ending operation requires the cooperation of two staff members. One staff member carefully observes the position of the molten pool. When it leaves the sheet material and continues to travel 2 - 3 cm on the height pad, immediately feedback to the cooperating staff member. After receiving the feedback, the other staff member immediately shuts down the cladding equipment and resets the cladding equipment.

[0048] Finally, referring to the second embodiment, during the process of the high-power wide-spot laser cladding device 9 performing cladding processing on the rotary cutting tool, the baffle 15 connected to the front end of the working platform 2 rises to block the spark splash generated during the cladding processing, avoiding the risk of scalding the skin of the worker caused by the spark splash at the front end of the working platform 2 and enhancing the safety of the working environment.

[0049] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
