Description

Technical Field

[0001] This application relates to the technical field of cladding machines, and in particular to a laser cladding machine for die-cutting production. Background Technology

[0002] Laser cladding machines use a high-power-density laser beam to heat the surface of a material in a non-contact manner, and then simultaneously feed in cladding material (powder / filament). Under a protective atmosphere, the cladding material is heated and melted, and then quickly solidifies on the surface of the substrate to form a cladding layer with different microstructures. This process is repeated to accumulate and form printed parts.

[0003] In the prior art, there is a die-cutting process that uses a laser cladding machine to produce die-cutting dies. That is, the laser cladding machine forms the blade shape on the surface of a cylindrical die-cutting die or a flat die-cutting die. However, the laser cladding machine in the prior art has poor adaptability and can only process either cylindrical die-cutting dies or flat die-cutting dies. Therefore, this application proposes a laser cladding machine for die-cutting production. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this application is to provide a laser cladding machine for die-cutting production, which enables the laser cladding machine to process both cylindrical and flat die-cutting machines, thereby improving the applicability of the laser cladding machine and saving die-cutting production costs.

[0005] The above-mentioned objective of this application is achieved through the following technical solution: a laser cladding machine for die-cutting production, comprising a horizontal machine tool body, a slide rail disposed inside the horizontal machine tool body and arranged along the length direction of the horizontal machine tool, a tailstock slidably mounted on the slide rail and facing the three-jaw chuck, and a laser cladding system mounted on one side of the slide rail, characterized in that it further comprises a telescopic platform installed between the three-jaw chuck and the tailstock for placing a flat die-cutting plate, the telescopic platform comprising two telescopic cylinders and a support plate assembly, the two telescopic cylinders being respectively mounted on both sides of the slide rail, the support plate assembly being mounted on the output ends of the two telescopic cylinders, the two telescopic cylinders being used to provide support for the support plate assembly, and the output ends of the telescopic cylinders facing upwards.

[0006] By adopting the above technical solution, under normal conditions, the support plate assembly is attached to the surface of the slide rail. At this time, the operator can use a three-jaw chuck to clamp one end of the cylindrical die, and then push the tailstock along the slide rail towards the three-jaw chuck, so that the tailstock presses against the other end of the cylindrical die. The operator can then operate the laser cladding system in conjunction with the three-jaw chuck to clad the cylindrical die. During this process, the support plate assembly attached to the slide rail surface will not block or obstruct the cylindrical die. When the operator needs to process a flat die, they only need to push the tailstock away from the three-jaw chuck to move it along the slide rail, providing support for the support plate assembly. With the upward space, the operator only needs to activate the telescopic cylinder to extend it, causing the output end of the telescopic cylinder to push the support plate assembly upward until the support plate assembly and the center of the three-jaw chuck are on the same horizontal line. At this point, the flat die-cutting mold can be placed on the support plate assembly, and then the laser cladding system can be used to clad the flat die-cutting mold. This allows the operator to control the lifting and lowering of the support plate assembly, enabling the laser cladding machine to process both round roller dies and flat die-cutting molds. This improves the applicability of the laser cladding machine, saves die-cutting mold production costs, and eliminates the need for die-cutting mold factories to prepare two different laser cladding machines.

[0007] Furthermore, the support plate assembly includes a carrier plate, a connection port on the end face of the carrier plate near the tailstock, a connecting plate that is slidably inserted into the carrier plate through the connection port, an insertion interface on the end face of the connecting plate near the tailstock, and an extension plate that is inserted into the connecting plate through the insertion interface.

[0008] While the telescopic platform allows the horizontal laser cladding machine to process both cylindrical and flat die-cutting molds, in actual production, if the length of the cylindrical die-cutting mold is shorter than the length of the support plate assembly, the support plate assembly attached to the slide rail, although not obstructing or blocking the die-cutting mold, will block the tailstock's forward path. This prevents the tailstock from engaging with the three-jaw chuck to hold the die-cutting mold in place. Although processing is still possible, the lack of a tailstock to hold the other end of the die-cutting mold may cause it to tilt. The design of the support plate assembly... This design solves the technical problem by setting the support plate assembly as a carrier plate, a connecting plate, and an extension plate. When the length of the cylindrical die is less than the overall length of the support plate assembly, the operator only needs to push the extension plate towards the three-jaw chuck to retract it into the connecting plate. If the length of the support plate assembly is still greater than the cylindrical die, the operator only needs to push the connecting plate towards the three-jaw chuck again to retract it into the carrier plate. This reduces the overall length of the support plate assembly, prevents it from obstructing the forward path of the tailstock, and allows the tailstock to hold the other end of the cylindrical die, thus improving the applicability of the support plate assembly.

[0009] Furthermore, the two telescopic cylinders are located at one end of the slide rail near the three-jaw chuck, and an installation assembly is installed on the output end of the telescopic cylinder. The support plate assembly is installed on the output end of the telescopic cylinder through the installation assembly.

[0010] Furthermore, the mounting assembly includes mounting blocks respectively mounted on the output ends of the two telescopic cylinders, mounting shafts respectively passing through the two mounting blocks and rotatably connected to the corresponding mounting blocks, the support plate assembly being located between the two mounting blocks, and the end of the bearing plate away from the tailstock being fixedly connected to the mounting shaft.

[0011] By adopting the above technical solution, although the support plate group is set as a bearing plate, connecting plate and extension plate, the applicability of the support plate group is improved. However, when the length of the cylindrical die is less than the length of the bearing plate, the tailstock is still restricted, which leads to certain limitations of the laser cladding machine in this application. The setting of the installation component solves this technical problem. With the setting of the installation component, when the length of the cylindrical die is less than the length of the bearing plate, the operator only needs to push the extension plate into the connecting plate, then push the connecting plate into the bearing plate, and then rotate the bearing plate to make it vertical, so that the entire support plate group is vertical. At this time, the entire support plate group will not occupy the space of the slide rail, so that the tailstock can move further to support the cylindrical die with a length less than the bearing plate. Moreover, because the length of the entire support plate group is reduced to the minimum, the vertical support plate group will not affect the clamping of the cylindrical die, further improving the applicability of the support plate group.

[0012] Furthermore, the bottom surface of the support plate assembly and the side of the tailstock bottom end near the support plate assembly are provided with support structures.

[0013] Furthermore, the support structure includes a connecting screw hole, a connecting block, a threaded sleeve, and a support screw. The connecting screw hole is opened on the bottom surface of the support plate assembly at the end away from the three-jaw chuck. The connecting block is fixedly installed on the bottom end of the tailstock near the support plate assembly. The threaded sleeve is fixedly installed on the end of the connecting block near the support plate assembly and extends upward. The support screw is threadedly connected to the upper end of the threaded sleeve. The support screw is threadedly connected to the support plate assembly through the connecting screw hole.

[0014] While the above technical solution enhances the applicability of the support plate assembly by incorporating the mounting components, a problem arises when workers need to use it to process the flat die. One end of the support plate assembly rotates due to the mounting components, preventing the die from being stably secured and hindering processing. The support structure solves this problem. When processing the flat die, workers simply extend the telescopic cylinder, pushing the support plate assembly upwards until it aligns with the center of the three-jaw chuck. Then, the support plate assembly is rotated into a flat shape. Next, adjust the length of the support plate assembly by pulling the extension plate or connecting plate according to the length of the flat die. After adjustment, push the tailstock towards the support plate assembly to move it. At the same time, move the support screw to the bottom of the support plate assembly so that the support screw is aligned with the connecting screw hole. At this time, the operator only needs to turn the support screw to move it upward and connect it to the support plate assembly through the connecting screw hole. This will provide support for the support plate assembly, prevent the support plate assembly from rotating, and provide stable support for the flat die. Because the support structure is set on the tailstock, it can move with the sliding of the tailstock, so that the support structure can provide support for the support plate assembly no matter what length it is extended or retracted.

[0015] Furthermore, the upper surface of the connecting plate and the upper surface of the extension plate are provided with a correction structure, so that the upper surfaces of the connecting plate, the extension plate and the bearing plate are flush.

[0016] Furthermore, the correction structure includes a correction spring and a correction plate. The upper surface of the connecting plate and the upper surface of the extension plate are provided with receiving grooves for accommodating the correction structure. The correction spring is vertically fixed in the receiving groove. The correction plate is slidably inserted into the receiving groove. The top of the correction spring is connected to the bottom surface of the correction plate. The correction spring is used to push the correction plate so that the upper surface of the correction plate is flush with the upper surface of the bearing plate.

[0017] By adopting the above technical solution, although the support plate assembly is configured as a carrier plate, connecting plate, and extension plate, improving the applicability of the support plate assembly, the insertion of the connecting plate into the carrier plate and the insertion of the extension plate into the connecting plate inevitably leads to a height difference between the upper surfaces of the connecting plate and the extension plate. This height difference may cause the flat die placed on the support plate assembly to tilt, resulting in errors when the subsequent laser cladding system clads the flat die. The setting of the correction structure solves this technical problem. With the setting of the correction structure, when the operator pulls the connecting plate or extension plate out of the carrier plate or connecting plate, the correction spring pushes the correction plate to move upward, making the upper surface of the correction plate flush with the upper surface of the carrier plate. In this way, when the operator places the flat die on the support plate assembly, there will be no tilting, improving the processing accuracy of the laser cladding system.

[0018] Furthermore, the connecting plate has a double limiting structure on the front and rear sides of its bottom surface, and the extension plate has a single limiting structure on its bottom surface. Both the double limiting structure and the single limiting structure are used to prevent the correction plate from shrinking after being subjected to the pressure of the flat die.

[0019] Furthermore, the double-limiting structure includes two limiting screw holes and two limiting screws. The two limiting screw holes are respectively opened on the front and rear sides of the bottom surface of the connecting plate and extend into the receiving groove. The two limiting screws are respectively threaded to the connecting plate through the two limiting screw holes and extend into the receiving groove. The single-limiting structure includes a positioning screw hole and a positioning screw. The positioning screw hole is opened on the bottom surface of the extension plate and extends into the receiving groove. The positioning screw is threaded to the extension plate through the positioning screw hole and extends into the receiving groove.

[0020] While the above technical solution prevents the flat die from tilting on the support plate assembly, the pressure exerted by the flat die on the correction plate during actual use may cause the correction plate to compress the correction spring and retract into the receiving groove. This can lead to the upper surface of the correction plate no longer being flush with the upper surface of the support plate, potentially causing the flat die to tilt on the support plate assembly. The double-limit structure and single-limit structure solve this problem. With the double-limit structure, when the operator pulls the connecting plate out of the support plate, the correction spring pushes the correction plate flush with the support plate. Then, the operator only needs to use a screwdriver or other tool capable of tightening the limit screw to move it upwards and abut against the correction plate. On the bottom surface, the limiting screw provides rigid support for the correction plate, preventing it from shrinking under the pressure of the flat die. Similarly, when the worker pulls the extension plate out of the connecting plate, the correction spring pushes the correction plate flush with the support plate. The worker only needs to use a screwdriver or other tool that can turn the positioning screw to move it upward and abut against the bottom surface of the correction plate. At this time, the positioning screw provides rigid support for the correction plate, preventing it from shrinking under the pressure of the flat die, further preventing the flat die from tilting on the support plate assembly. Moreover, because the two limiting screw holes and the limiting screw in the double limiting structure are on the front and rear sides of the connecting plate, they will not occupy the space in the middle of the connecting plate, allowing the extension plate to be properly inserted into the connecting plate.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a telescopic platform and controlling the lifting and lowering of the support plate group, the laser cladding machine can process both round roller dies and flat die-cutting machines, thereby improving the applicability of the laser cladding machine and saving die-cutting production costs. This eliminates the need for die-cutting factories to prepare two different laser cladding machines.

[0022] 2. By setting up the support plate assembly, when the length of the cylindrical die is less than the overall length of the support plate assembly, simply push the extension plate towards the three-jaw chuck to retract the extension plate into the connecting plate. If the length of the support plate assembly is still greater than the cylindrical die, simply push the connecting plate towards the three-jaw chuck again to retract the connecting plate into the bearing plate, thereby reducing the overall length of the support plate assembly, preventing the support plate assembly from obstructing the forward path of the tailstock, and allowing the tailstock to hold the other end of the cylindrical die, thus improving the applicability of the support plate assembly.

[0023] 3. By installing components in conjunction with the support plate assembly, when the length of the cylindrical die is less than the length of the bearing plate, the operator only needs to push the extension plate into the connecting plate, then push the connecting plate into the bearing plate, and then rotate the bearing plate to make it vertical, so that the entire support plate assembly is vertical. At this time, the entire support plate assembly will not occupy the space of the slide rail, allowing the tailstock to move further to hold the cylindrical die whose length is less than that of the bearing plate. Moreover, because the length of the entire support plate assembly is reduced to the minimum, the vertical support plate assembly will not affect the clamping of the cylindrical die, further improving the applicability of the support plate assembly.

[0024] 4. By setting up the support structure, support is provided for the support plate assembly, preventing the support plate assembly from rotating and providing stable support for the flat die. Since the support structure is set on the tailstock, it can move with the sliding of the tailstock, so that the support structure can provide support for the support plate assembly no matter what length it is extended or contracted.

[0027] The present application will be further described in detail below with reference to the accompanying drawings.

[0028] The die-cutting process utilizes a laser cladding machine to produce die-cutting molds. This involves forming the blade shape on the surface of a cylindrical or flat die-cutting mold using the laser cladding machine. However, existing laser cladding machines present a technical problem: die-cutting molds are divided into cylindrical and flat die-cutting molds. This necessitates two different laser cladding machines for a factory to produce both types: a horizontal laser cladding machine and a vertical laser cladding machine. The difference lies in the machine's design: the horizontal machine uses a three-jaw chuck and a movable tailstock to fix the cylindrical die-cutting mold, while the vertical machine uses a movable limiting post to restrict the flat die-cutting mold. Engineers have considered adding a placement platform to the horizontal laser cladding machine to hold the flat die-cutting mold, allowing the machine to process both cylindrical and flat dies. However, this platform occupies the space between the three-jaw chuck and the movable tailstock, obstructing the processing of the cylindrical die-cutting mold. Therefore, this embodiment proposes a laser cladding machine for die-cutting mold production.

[0029] Reference Figure 1 A laser cladding machine for die-cutting production includes a horizontal machine tool body 1, a three-jaw chuck 10 disposed on one side inside the horizontal machine tool body 1, a slide rail 11 disposed inside the horizontal machine tool body and disposed along the length of the horizontal machine tool, a tailstock 12 slidably mounted on the slide rail 11 and facing the three-jaw chuck 10, a laser cladding system 13 mounted on one side of the slide rail 11, and a telescopic platform 2 mounted between the three-jaw chuck 10 and the tailstock 12 for placing flat die-cutting plates. The telescopic platform 2 includes two telescopic cylinders 20 and a support plate assembly 21. The two telescopic cylinders 20 are respectively mounted on both sides of the slide rail 11, and the support plate assembly 21 is mounted on the output ends of the two telescopic cylinders 20. The two telescopic cylinders 20 are used to provide support for the support plate assembly 21, and the output ends of the telescopic cylinders 20 face upward.

[0030] The horizontal machine tool body 1 is specifically a rectangular base, with a machine housing on the base. A notch is provided on one side of the machine housing, and a three-jaw chuck 10 is provided on the side of the machine housing with the notch. The tailstock 12 and the laser cladding system 13 are existing technologies and will not be described in detail here.

[0031] Under normal conditions, the support plate assembly 21 is attached to the surface of the slide rail 11. At this time, the operator can use the three-jaw chuck 10 to clamp one end of the cylindrical die, and then push the tailstock 12 along the slide rail 11 in the direction of the three-jaw chuck 10 so that the tailstock 12 presses against the other end of the cylindrical die. At this time, the operator can operate the laser cladding system 13 in conjunction with the three-jaw chuck 10 to clad the cylindrical die. At this time, the support plate assembly 21 attached to the surface of the slide rail 11 will not block or obstruct the cylindrical die. When the operator needs to process a flat die, they only need to push the tailstock 12 away from the three-jaw chuck 10 to move along the slide rail 11, thereby providing upward space for the support plate assembly 21. At this time, the operator only needs to activate the telescopic cylinder 20 to extend, so that the output end of the telescopic cylinder 20 pushes the support plate assembly 21 upward until the support plate assembly 21 and the center of the three-jaw chuck 10 are on the same horizontal line. At this time, the flat die is placed on the support plate assembly 21, and then the flat die is clad by the laser cladding system 13. This allows the operator to control the lifting and lowering of the support plate assembly 21 to enable the laser cladding machine to process both round and flat dies, thereby improving the applicability of the laser cladding machine and saving die production costs. This eliminates the need for die factories to prepare two different laser cladding machines.

[0032] In other embodiments, the telescopic cylinder 20 can be replaced by an electric cylinder or a hydraulic cylinder, and can be flexibly selected as needed in practical applications.

[0033] Although the telescopic platform 2 enables the horizontal laser cladding machine to process both cylindrical and flat die-cutting molds, in actual production, if the length of the cylindrical die-cutting mold is less than the length of the support plate group 21, the support plate group 21 attached to the slide rail 11 will not obstruct or block the cylindrical die-cutting mold, but it will block the forward path of the tailstock 12. This prevents the tailstock 12 from working with the three-jaw chuck 10 to hold the cylindrical die-cutting mold in place. Although the cylindrical die-cutting mold can still be processed, the lack of the tailstock 12 holding the other end of the cylindrical die-cutting mold may cause the cylindrical die-cutting mold to tilt. To solve this technical problem, in this embodiment, the support plate group 21 is configured to include a bearing plate 210, a connection port on the end face of the bearing plate 210 near the tailstock 12, a connecting plate 211 slidably inserted into the bearing plate 210 through the connection port, an insertion interface on the end face of the connecting plate 211 near the tailstock 12, and an extension plate 212 inserted into the connecting plate 211 through the insertion interface.

[0034] By configuring the support plate assembly 21 as a bearing plate 210, a connecting plate 211, and an extension plate 212, when the length of the cylindrical die is less than the overall length of the support plate assembly 21, the operator only needs to push the extension plate 212 towards the three-jaw chuck 10, causing the extension plate 212 to retract into the connecting plate 211. If the length of the support plate assembly 21 is still greater than the cylindrical die, the operator only needs to push the connecting plate 211 towards the three-jaw chuck 10 again, causing the connecting plate 211 to retract into the bearing plate 210, thereby reducing the overall length of the support plate assembly 21 and preventing the support plate assembly 21 from obstructing the forward path of the tailstock 12. This allows the tailstock 12 to hold the other end of the cylindrical die, improving the applicability of the support plate assembly 21.

[0035] Although the support plate assembly 21 is configured as a bearing plate 210, a connecting plate 211, and an extension plate 212, which improves the applicability of the support plate assembly 21, the tailstock 12 is still restricted when the length of the cylindrical die is less than the length of the bearing plate 210. This results in certain limitations of the laser cladding machine in this embodiment. To solve this technical problem, this embodiment sets two telescopic cylinders 20 at one end of the slide rail 11 near the three-jaw chuck 10, and installs an installation assembly 3 on the output end of the telescopic cylinders 20. The support plate assembly 21 is installed on the output end of the telescopic cylinders 20 through the installation assembly 3. The installation assembly 3 includes installation blocks 30 respectively installed on the output ends of the two telescopic cylinders 20, and installation shafts 31 that pass through the two installation blocks 30 and are rotatably connected to the corresponding installation blocks 30. The support plate assembly 21 is located between the two installation blocks 30, and the end of the bearing plate 210 away from the tailstock 12 is fixedly connected to the installation shaft 31.

[0036] The mounting block 30 can be installed on the output end of the telescopic cylinder 20 by means of threading, welding or snap-fit.

[0037] With the installation of component 3, when the length of the cylindrical die is less than the length of the support plate 210, the operator only needs to push the extension plate 212 into the connecting plate 211, then push the connecting plate 211 into the support plate 210, and then rotate the support plate 210 to make it vertical, so that the entire support plate assembly 21 is vertical. At this time, the entire support plate assembly 21 will not occupy the space of the slide rail 11, allowing the tailstock 12 to move further to hold the cylindrical die whose length is less than that of the support plate 210. Since the length of the entire support plate assembly 21 is reduced to the minimum, the vertical support plate assembly 21 will not affect the clamping of the cylindrical die, further improving the applicability of the support plate assembly 21.

[0038] Although the installation component 3 further improves the applicability of the support plate assembly 21, when workers need to use the support plate assembly 21 to process the flat die, the installation component 3 causes one end of the support plate assembly 21 to rotate, making it impossible to stably hold the flat die on the support plate assembly 21, thus preventing the flat die from being processed. To solve this technical problem, this embodiment provides a support structure 4 on the bottom surface of the support plate assembly 21 and the side of the tailstock 12 near the support plate assembly 21. The support structure 4 includes a connecting screw hole 40 (see reference). Figure 2 The assembly includes a connecting block 41, a threaded sleeve 42, and a support screw 43. A connecting screw hole 40 is opened on the bottom surface of the support plate assembly 21 at the end away from the three-jaw chuck 10. The connecting block 41 is fixedly installed on the bottom end of the tailstock 12 near the support plate assembly 21. The threaded sleeve 42 is fixedly installed on the end of the connecting block 41 near the support plate assembly 21 and extends upward. The support screw 43 is threadedly connected to the upper end of the threaded sleeve 42 and is threaded to the support plate assembly 21 through the connecting screw hole 40.

[0039] The connecting screw hole 40 is mainly opened on the bottom surface of the end of the bearing plate 210 away from the three-jaw chuck 10, the bottom surface of the connecting plate 211 away from the three-jaw chuck 10, and the bottom surface of the extension plate 212 away from the three-jaw chuck 10. It does not penetrate the bearing plate 210, the connecting plate 211, and the extension plate 212. The connecting block 41 can be installed on the tailstock 12 by fixed insertion, welding, bonding, or magnetic attraction. The threaded sleeve 42 can be installed on the connecting block 41 by snap-fit, fixed insertion, welding, bonding, or thread.

[0040] With the support structure 4 in place, when the operator needs to process a flat die, they only need to activate the telescopic cylinder 20 to extend it, causing the output end of the telescopic cylinder 20 to push the support plate assembly 21 upward until the support plate assembly 21 and the center of the three-jaw chuck 10 are on the same horizontal line. Then, the support plate assembly 21 is rotated into a flat state. Next, the extension plate 212 or connecting plate 211 is pulled according to the length of the flat die to adjust the length of the support plate assembly 21. After adjustment, the tailstock 12 is pushed towards the support plate assembly 21, causing the tailstock 12 to move and simultaneously driving the support screw 4. 3. Move the support plate assembly 21 below so that the support screw 43 is aligned with the connecting screw hole 40. At this time, the operator only needs to turn the support screw 43 to move it upward and connect it to the support plate assembly 21 through the connecting screw hole 40. This will provide support for the support plate assembly 21, prevent the support plate assembly 21 from rotating, and provide stable support for the flat die. Since the support structure 4 is set on the tailstock 12, it can move with the sliding of the tailstock 12. This ensures that the support structure 4 can provide support for the support plate assembly 21 no matter what length it is extended or retracted to.

[0041] In other embodiments, the bottom surface of the support plate assembly 21 may not have connecting screw holes 40. When support is needed for the support plate assembly 21, simply tighten the support screw 43 to move it upwards and hold the support plate assembly 21 in place. Moreover, compared to the support structure 4 in this embodiment, the method of not having connecting screw holes 40 eliminates the need for drilling, making the installation method and manufacturing of the support plate assembly 21 simpler. On the other hand, since the support plate assembly 21 is composed of a bearing plate 210, a connecting plate 211, and an extension plate 212, the connecting plate 211 or the extension plate 212, which is only held in place during processing, may shift. This could lead to the support screw 43 detaching from the support plate assembly 21 if the connecting screw holes 40 are not provided. In this embodiment, the cooperation between the support screw 43 and the connecting screw holes 40 ensures that the support screw 43 can stably restrain the support plate assembly 21, preventing the connecting plate 211 or the extension plate 212 from shifting. In practical applications, a specific structure of the support structure 4 can be flexibly selected as needed.

[0042] Although configuring the support plate assembly 21 as a carrier plate 210, a connecting plate 211, and an extension plate 212 improves its applicability, the insertion of the connecting plate 211 into the carrier plate 210 and the extension plate 212 into the connecting plate 211 inevitably results in a height difference between the upper surfaces of the connecting plate 211 and the extension plate 212. This height difference may cause the flat die placed on the support plate assembly 21 to tilt, leading to errors when the laser cladding system 13 clads the flat die. To solve this technical problem, refer to... Figure 3 as well as Figure 4 In this embodiment, a correction structure 5 is provided on the upper surface of the connecting plate 211 and the upper surface of the extension plate 212. The correction structure 5 includes a correction spring 50 and a correction plate 51. The upper surface of the connecting plate 211 and the upper surface of the extension plate 212 are provided with receiving grooves for accommodating the correction structure 5. The correction spring 50 is vertically fixed in the receiving groove. The correction plate 51 is slidably inserted into the receiving groove. The top of the correction spring 50 is connected to the bottom surface of the correction plate 51. The correction spring 50 is used to push the correction plate 51 so that the upper surface of the correction plate 51 is flush with the upper surface of the bearing plate 210.

[0043] The corrective spring 50 can be installed in the receiving groove of the connecting plate 211 and the receiving groove of the extension plate 212 by means of adhesive bonding or welding. The corrective plate 51 can also be connected to the corrective spring 50 by means of adhesive bonding or welding.

[0044] By setting the correction structure 5, when the worker pulls the connecting plate 211 or the extension plate 212 out of the bearing plate 210 or the connecting plate 211, the correction spring 50 pushes the correction plate 51 to move upward, so that the upper surface of the correction plate 51 is flush with the upper surface of the bearing plate 210. In this way, when the worker places the flat die on the support plate group 21, there will be no tilting, which improves the processing accuracy of the laser cladding system 13.

[0045] In other embodiments, the corrective spring 50 can be replaced with an inflatable bladder. After the connecting plate 211 or the extension plate 212 is pulled out of the support plate 210 or the connecting plate 211, air is injected into the inflatable bladder to move the corrective plate 51 upward and make it flush with the support plate 210. This also prevents the flat die from tilting on the support plate assembly 21. However, compared to the corrective structure 5 in this embodiment, the corrective structure 5 using an inflatable bladder requires air to be injected into the bladder. In contrast, the corrective structure 5 in this embodiment automatically pushes the corrective plate 51 to be flush with the support plate 210 after the connecting plate 211 or the extension plate 212 extends out of the support plate 210 or the connecting plate 211. The corrective structure 5 in this embodiment is more convenient to use than the corrective structure 5 using an inflatable bladder. In practical applications, a specific structure of the support structure 4 can be flexibly selected as needed.

[0046] Although the correction structure 5 can prevent the flat die from tilting on the support plate assembly 21, in actual use, the pressure exerted by the flat die on the correction plate 51 may cause the correction plate 51 to compress the correction spring 50 and retract into the receiving groove. This can cause the upper surface of the correction plate 51 to no longer be flush with the upper surface of the support plate 210, potentially leading to tilting of the flat die on the support plate assembly 21. To solve this technical problem, refer to... Figure 4 as well as Figure 5 In this embodiment, a double limiting structure 6 is provided on the front and rear sides of the bottom surface of the connecting plate 211, and a single limiting structure 7 is provided on the bottom surface of the extension plate 212. The double limiting structure 6 includes two limiting screw holes 60 and two limiting screws 61. The two limiting screw holes 60 are respectively opened on the front and rear sides of the bottom surface of the connecting plate 211 and extend into the receiving groove. The two limiting screws 61 are respectively threaded to the connecting plate 211 through the two limiting screw holes 60 and extend into the receiving groove. The single limiting structure 7 includes a positioning screw hole 70 and a positioning screw 71. The positioning screw hole 70 is opened on the bottom surface of the extension plate 212 and extends into the receiving groove. The positioning screw 71 is threaded to the extension plate 212 through the positioning screw hole 70 and extends into the receiving groove.

[0047] With the double-limiting structure 6, when the worker pulls the connecting plate 211 to extend the support plate 210, the adjusting spring 50 pushes the adjusting plate 51 to be flush with the support plate 210. Then, the worker only needs to use a screwdriver or other tool capable of turning the limiting screw 61 to move it upwards and abut against the bottom surface of the adjusting plate 51. At this time, the limiting screw 61 provides rigid support for the adjusting plate 51, preventing it from shrinking under the pressure of the flat die. Similarly, when the worker pulls the extension plate 212 to extend the connecting plate 211, the adjusting spring 50 pushes the adjusting plate 51 to be flush with the support plate 210. Workers only need to use a screwdriver or other tools that can turn the positioning screw 71 to move it upwards and abut against the bottom surface of the correction plate 51. At this time, the positioning screw 71 provides rigid support for the correction plate 51, preventing the correction plate 51 from shrinking under the pressure of the flat die, and further preventing the flat die from tilting on the support plate assembly 21. In addition, because the two limiting screw holes 60 and the limiting screw 61 in the double limiting structure 6 are on the front and rear sides of the connecting plate 211, they will not occupy the space in the middle of the connecting plate 211, so that the extension plate 212 can still be properly inserted into the connecting plate 211.

[0048] Specific implementation process: When it is necessary to process the cylindrical die, simply use the three-jaw chuck 10 to clamp one end of the cylindrical die. Then, compare the length of the cylindrical die with the support plate group 21, and push the extension plate 212 or connect it into the connecting plate 211 or the bearing plate 210 until the space occupied by the slide rail 11 of the support plate group 21 is enough for the tailstock 12 to move and press against the cylindrical die. If it is still not enough, rotate the support plate group 21 to a vertical position. At this time, simply push the tailstock 12 along the slide rail 11 in the direction of the three-jaw chuck 10 so that the tailstock 12 presses against the other end of the cylindrical die. Then, operate the laser cladding system 13 in conjunction with the three-jaw chuck 10 to clad the cylindrical die.

[0049] When cladding is required on the flat die, simply push the tailstock 12 away from the three-jaw chuck 10 to move it along the slide rail 11 to provide upward space for the support plate assembly 21. Then, activate the telescopic cylinder 20 to extend it, causing the output end of the telescopic cylinder 20 to push the support plate assembly 21 upward until the support plate assembly 21 and the center of the three-jaw chuck 10 are on the same horizontal line. Then, pull the extension plate 212 or connecting plate 211 out of the connecting plate 211 or bearing plate 210 according to the length of the flat die, so that the length of the support plate assembly 21 matches the length of the flat die. Then, move the support plate assembly 21 in the direction of... Push the tailstock 12 to move it. At the same time, the tailstock 12 drives the support screw 43 to move below the support plate assembly 21, so that the support screw 43 is aligned with the connecting screw hole 40. At this time, simply turn the support screw 43 to move it upward and connect it to the support plate assembly 21 through the connecting screw hole 40 to support the support plate assembly 21. Then, according to the pulled-out extension plate 212 or connecting plate 211, turn the positioning screw 71 or the limiting screw 61 to support the correction plate 51. Then, place the flat die on the support plate assembly 21 and then perform laser cladding on the flat die through the laser cladding system 13.

Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
