[0002] The additive and subtractive manufacturing of the barrel of the die-casting machine is to increase the service life of the barrel. Traditional methods include carburizing, quenching, nitriding, etc. However, in recent years, laser cladding technology has replaced traditional processing methods. Laser cladding refers to the laser generating a molten pool on the surface of the component, automatically adding metal powder to it through the nozzle to form weld beads that are welded to each other. It can form a coating on the existing substrate or form the entire component. It can give the substrate itself special mechanical (mechanical), physical, and chemical properties that do not have, so as to improve the quality and performance of the components and extend their service life. The method is simple, efficient, less polluting, and has many advantages such as high utilization rate; and the cladding state inside the barrel can also be transmitted to the computer in real time through a visual sensor.

DETAILED DESCRIPTION

[0029] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and cannot be understood as limiting the specific scope of protection of the present application.

[0031] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0032] One of the preferred embodiments of the present application is as follows: Figures 1 to 11 As shown, a die-casting machine barrel additive and subtractive material remanufacturing device includes a machine tool 1, a barrel component 2 (i.e., a die-casting machine barrel to be processed), a moving mechanism 3, a processing device 4, and a supporting device 5, wherein the barrel component 2 is horizontally mounted on a three-jaw chuck 101 of the machine tool 1, the moving mechanism 3 is mounted on the machine tool 1, the processing device 4 is horizontally mounted on the moving mechanism 3 through a boring bar 6, that is, the first end of the boring bar 6 is mounted on the moving mechanism 3, the processing device 4 is mounted on the second end of the boring bar 6, and the supporting device 5 is mounted on the machine tool 1 and cooperates with the barrel component 2.

[0033] It can be understood that the processing device 4 is first adjusted by the moving mechanism 3 so that the processing device 4 extends into the appropriate position in the barrel member 2, and then the processing device 4 performs laser cladding and boring processing on the barrel member 2 under the action of the moving mechanism 3, wherein the laser cladding process clads the metal powder on the inner wall of the barrel member 2 to form a coating with special properties, thereby improving the service life and performance of the barrel member 2. The boring process is to bore the inner wall of the barrel member 2 after cladding by a boring tool 402 to improve the surface finish and the surface quality of the workpiece. During the processing, the support device 5 plays the role of limiting the support of the barrel member 2, ensuring that the barrel member 2 is in a horizontal state, preventing the barrel member 2 from bending and deformation, thereby improving the processing accuracy and stability.

[0034] As a further description of the above embodiment: Figures 7 to 9 As shown, the supporting device 5 includes a pair of rollers 503 , an adjusting component 1 501 and an adjusting component 2 502 . The adjusting component 1 501 is installed on the machine tool 1 , the adjusting component 2 502 is installed on the adjusting component 1 501 , and the rollers 503 are installed on the adjusting component 2 502 .

[0035] It is understandable that during the processing of the barrel member 2, the barrel member 2 is supported and limited by the roller 503. The setting of the roller 503 is to reduce the friction resistance when supporting the barrel member 2, so that the barrel member 2 can rotate smoothly during the processing. The coordinated use of the adjustment component 1 501 and the adjustment component 2 502 realizes the precise adjustment of the height and spacing of the roller 503 to meet the processing requirements of barrel members 2 of different specifications and sizes. Specifically, the adjustment component 1 501 can drive the roller 503 to rise and fall in the vertical direction, ensuring that the roller 503 can fit closely to the outer wall of the barrel member 2 and provide a stable supporting force. The adjustment component 2 502 can adjust the distance between the two rollers 503 to adapt to barrel members 2 of different diameters, ensuring the applicability and flexibility of the support device 5.

[0036] The present application does not specifically limit the structures of the adjustment component 1 501 and the adjustment component 2 502. A specific embodiment is provided below for reference: like Figure 8 and Fig. 9 As shown, the adjustment component 1 501 includes a housing 5011, a worm 5013, a worm wheel 5012, a gear 5015 and a rack 5014, wherein the worm 5013 is horizontally rotatably installed in the housing 5011, the worm wheel 5012 is rotatably installed in the housing 5011 through a rotating shaft and meshes with the worm 5013, the gear 5015 is sleeved and installed on the rotating shaft, and the rack 5014 is vertically slidably installed in the housing 5011 and the top end is connected to the adjustment component 2 502.

[0037] It is understandable that when the height is adjusted, the worm 5013 is rotated by the crank, and the worm 5013 acts on the worm wheel 5012, and the worm wheel 5012 drives the rotating shaft to rotate, so that the gear 5015 rotates and acts on the rack 5014, and the rack 5014 can drive the adjustment component 2 502 and the roller 503 to move up and down. It should be known that there is self-locking between the worm wheel 5012 and the worm 5013; therefore, after the adjustment is completed, after the worm 5013 stops rotating, it can also ensure that the height position of the roller 503 is stable, thereby further improving the stability and accuracy of the processing. In addition, the transmission ratio of the worm wheel 5012 and the worm 5013 is large, which has the effect of reducing speed and increasing torque, so that the operator can achieve accurate adjustment of the height of the roller 503 with less force, improving the convenience of operation. Of course, the adjustment component 1 501 can also be adjusted automatically, for example, by a hydraulic cylinder or a pneumatic cylinder.

[0038] like Fig.10 and Fig.11As shown, the adjustment component 2 502 includes a support plate 5021, a bidirectional screw rod 5022, a pair of connecting rods 5023, a pair of traction blocks 5024 and a guide rail 5025, wherein the support plate 5021 is fixedly installed on the top of the rack 5014, the connecting rod 5023 is rotatably installed on both sides of the top of the support plate 5021 through the bottom and is symmetrically distributed, the roller 503 is installed on the top of the connecting rod 5023, the traction block 5024 is rotatably installed in the middle of the connecting rod 5023 and is threadedly matched with the bidirectional screw rod 5022, and the guide rail 5025 is vertically installed in the middle of the support plate 5021 and is matched with the bidirectional screw rod 5022.

[0039] Specifically, the bidirectional screw rod 5022 is a left-handed screw rod, the left-handed thread of the screw rod cooperates with one traction block 5024, and the right-handed thread of the screw rod cooperates with another traction block 5024, and the guide rail 5025 limits the vertical direction of the bidirectional screw rod 5022, so that the bidirectional screw rod 5022 can move in the vertical direction along the guide rail 5025 while rotating. It can be understood that when adjusting the spacing, the bidirectional screw rod 5022 is rotated by the crank handle, and the bidirectional screw rod 5022 will act on the two traction blocks 5024 to move relative to or away from each other, and the traction blocks 5024 will drive the two connecting rods 5023 to rotate relative to or away from each other, so that the two rollers 503 can rotate relatively to get closer or away from each other to achieve the spacing adjustment.

[0040] For example, Fig.11 As shown in the figure above, when the diameter of the barrel 2 is large, the two-way screw rod 5022 can be rotated clockwise, so that the two traction blocks 5024 move away from each other, that is, the two connecting rods 5023 drive the rollers 503 to rotate away from each other so that the distance increases and is adjusted to a suitable large distance. Similarly, when the diameter of the barrel 2 is small, such as Fig.11 As shown in the figure below, at this time, if the bidirectional screw rod 5022 is rotated counterclockwise, the distance between the two rollers 503 can be reduced and adjusted to a suitable small distance.

[0041] Of course, the adjustment component 2 502 mentioned above can also adopt such a structure (not shown): the adjustment component 2 502 includes a support plate 5021, a bidirectional screw rod 5022, a pair of connecting rods 5023 and a pair of traction blocks 5024, wherein the support plate 5021 is fixedly installed on the top of the rack 5014, the traction block 5024 is symmetrically slidably installed on the top of the support plate 5021, the bidirectional screw rod 5022 is horizontally rotatably installed on the top of the support plate 5021 and is threadedly matched with the traction block 5024, the connecting rod 5023 is fixedly connected to the top of the traction block 5024 through the bottom end, and the roller 503 is installed on the top of the connecting rod 5023; that is to say, this is equivalent to a "screw slider structure", that is, the two rollers 503 are directly driven to move relative to or away from each other under the rotation of the bidirectional screw rod 5022.

[0042] It should be noted that when the adjustment component 2 502 adopts the second form (i.e. the roller 503 adopts the mobile adjustment mode), in order to make the roller 503 have enough adjustment spacing, it is necessary to make the two traction blocks 5024 have enough sliding space, thereby increasing the length dimension of the support plate 5021. When the adjustment component 2 502 adopts the first form, i.e. the roller 503 is adjusted under the rotation of the connecting rod 5023, that is, the longer the length of the connecting rod 5023 is, the larger the adjustment range is, and the designer can reasonably set the actual length of the connecting rod 5023 according to the actual situation. It can be understood that within the same spacing adjustment range, the length dimension of the support plate 5021 required by the first form will be smaller, thereby making its structure more compact, thereby further reducing the occupied space of the entire device and improving the space utilization rate. Moreover, in actual support, the force exerted by the barrel member 2 on the connecting rod 5023 is not vertically downward, but acts obliquely on the connecting rod 5023. When form one is adopted, the bidirectional screw rod 5022 can also play the role of a limiting support for the two connecting rods 5023, thereby increasing the stability of the support of the connecting rod 5023.

[0043] In one of the embodiments of the present application, Figure 2 and Figure 3 As shown, the mobile mechanism 3 includes a mobile component 1 301, a mobile component 2 302 and a mobile component 3 303. The mobile component 1 301 is installed on the machine tool 1, the mobile component 2 302 is installed on the mobile component 1 301, the mobile component 3 303 is installed on the mobile component 2 302, and the processing device 4 is installed on the mobile component 3 303 through the boring bar 6.

[0044] It can be understood that, when performing movement adjustment, moving component 1 301 can drive moving component 2 302, moving component 3 303 and processing device 4 to move synchronously in the first direction; moving component 2 302 can drive moving component 3 303 and processing device 4 to move synchronously in the second direction, and moving component 3 303 is suitable for driving processing device 4 to move in the third direction; the three directions are different directions.

[0045] Specifically, Figure 1 As shown, we set the first direction to be the x direction (i.e., the left-right direction of the machine tool 1), the second direction to be the y direction (i.e., the front-back direction of the machine tool 1), and the third direction to be the z direction (i.e., the up-down direction of the machine tool 1), thereby realizing six degrees of freedom adjustment, so that the processing device 4 can perform all-round processing, greatly improving the processing flexibility and scope of application.

[0046] It should be known that the specific structures and working principles of the three moving components are well known to those skilled in the art, so they will not be described in detail here. Common moving components include slide rails and drive sources. Take the moving component 1 301 as an example: the slide rail is fixedly installed on the machine tool 1, and a slider is slidably installed in the slide rail. The moving component 2 302 is installed on this slider, and the slider is connected to the drive source, so that under the drive of the drive source, the slider can move along the slide rail (i.e., move in the x direction). Common drive sources include motors, cylinders, and hydraulic cylinders, etc., which can then form a motor screw slider device or a pneumatic slide rail device, etc.

[0047] In one of the embodiments of the present application, Figure 4 As shown, the processing device 4 includes a laser cladding head 401, a boring tool 402 and a support assembly 403. The laser cladding head 401 is installed in the boss 12 at the second end of the boring bar 6 (that is, the groove body opened at the second end of the boring bar 6), and the boring tool 402 is installed at the top of the boring bar 6 and close to the boss 12; the support assembly 403 is installed at the end of the boring bar 6 and cooperates with the inner bottom end of the barrel member 2.

[0048] It is understandable that during the processing, the laser cladding head 401 performs laser cladding on the barrel 2, and the boring tool 402 performs boring processing. During the boring process, the barrel 2 will give the boring tool 402 a reaction force. Since the barrel augmentation and subtraction remanufacturing belongs to deep hole processing, in order to prevent the augmentation and subtraction boring bar 6 from deforming during the operation, Figure 5 As shown, at this time, the support assembly 403 will abut against the inner bottom end of the barrel member 2, thereby playing a supporting role for the boring bar 6, increasing the rigidity of the boring bar 6 during the processing, and improving the processing accuracy and stability.

[0049] Specifically, Figure 4As shown, the support assembly 403 includes a telescopic member 4031 and a pulley 4032, wherein the telescopic member 4031 is mounted on the end of the boring bar 6, and the pulley 4032 is mounted on the piston end of the telescopic member 4031. During processing, the telescopic member 4031 can be extended so that the pulley 4032 moves until it abuts against the inner bottom end of the barrel member 2. The arrangement of the pulley 4032 can reduce the friction on the inner wall of the barrel member 2, making the support more stable. The telescopic member 4031 can be a cylinder or a hydraulic cylinder, etc., and a hydraulic cylinder is preferably used here because the stability and motion control accuracy of the hydraulic cylinder (rod) will be better.

[0050] The specific installation method of the boring tool 402 is as follows: Figure 4 As shown, a threaded hole 1 may be provided on the top side of the second end portion of the boring bar 6, and the boring tool 402 is installed in the threaded hole 1 through threads; a threaded hole 2 connected to the threaded hole 1 may be provided on the side portion of the boring bar 6, and a bolt may be provided in the threaded hole 2; an "I"-shaped groove may be provided at the bottom end of the boring tool 402, and an operating hole connected to the threaded hole 1 may be provided on the bottom side of the second end of the boring bar 6.

[0051] It can be understood that the boring tool 402 can be installed on the boring rod 6 through the threaded hole 1, and then a flat-blade screwdriver can be inserted from the operating hole and cooperate with the boring tool 402, so that the boring tool 402 can be slightly adjusted, and finally the boring tool 402 can be tightened by bolts to achieve the limited fixation (locking) of the boring tool 402 to prevent loosening during work.

[0052] Based on the above embodiments, in this embodiment, if Figure 4 As shown, the support assembly 403 can be installed on the second end of the boring bar 6 through the drive device 8. It can be understood that when the laser cladding head 401 is focusing, the drive device 8 can drive the support assembly 403 to rotate and move away from the focus area to avoid interference with the focus of the laser cladding head 401 and ensure the accuracy of the focus. When the focus is completed, the drive device 8 drives the support assembly 403 to rotate and reset. The specific structure and working principle of the drive device 8 can be designed according to actual needs, for example, a motor, a rotary cylinder or a rotary hydraulic cylinder can be used.

[0053] like Figure 4 As shown, the interior of the boring bar 6 is provided with an inner hole 11 connected to the boss 12, and the inner hole 11 can be arranged with components that cooperate with the laser cladding head 401, for example: used to transport the cooling pipe, powder delivery pipe, protective gas pipe and optical fiber required for laser cladding.

[0054] Further, such as Figure 4As shown, a pressure detection module 9 (such as a force sensor) can be installed between the boring bar 6 and the driving device 8, so that the force sensor can detect the force of the telescopic member 4031 (such as a hydraulic rod). The force sensor transmits the working data to an external computer in real time in the form of an electrical signal. By observing the fluctuation of the electrical signal, it can be obtained whether the material addition and subtraction operating rod is deformed during the working process or the uniformity of the laser cladding layer. Specifically: if the fluctuation value suddenly increases during the period, it means that the cladding layer at this place is too thick. If it increases for a long time, it means that the operating rod may be deformed due to the force; if the fluctuation value suddenly decreases, it means that the thickness of the cladding layer at this time is too thin.

[0055] Of course, if Figure 4 As shown, a camera 10 is also installed on the end (i.e., the second end) of the boring bar 6, which can transmit the state of the cladding layer observed during laser cladding and the good quality of the molten pool to an external computer. The focusing state of the laser during laser cladding can also be observed; the optical image generated by the lens (LENS) is projected onto the surface of the image sensor, and then converted into an electrical signal, which is converted into a digital image signal after A / D (analog-to-digital conversion), and then sent to the digital signal processing chip (DSP) for processing, and then transmitted to the computer through the USB interface for processing, and finally the image can be seen through the display.

[0056] Another aspect of the present application further provides a die-casting machine barrel material addition and subtraction remanufacturing process method, using the above-mentioned die-casting machine barrel material addition and subtraction remanufacturing device, comprising the following steps: S100: First, the barrel member 2 can be fixedly mounted on the three-jaw chuck 101 of the machine tool 1 by a suitable clamp 7; S200: Since the barrel member 2 is deep-hole processed, in order to prevent the barrel member 2 or the fixture 7 from deforming, the barrel member 2 may be supported and limited. Fig.10 and Fig.11 As shown, the bidirectional screw rod 5022 is rotated by the crank handle to make the two rollers 503 at a suitable angle, and then the worm 5013 is rotated by the crank handle to make the two rollers 503 move up until they abut against the barrel 2, so that the barrel 2 can be limited and supported and in a horizontal state; S300: Before the moving mechanism 3 moves the processing device 4 to the barrel member 2, the telescopic member 4031 is driven by the driving device 8 to rotate to the other side of the boring bar 6 to facilitate the calibration process of the processing device 4. The telescopic member 4031 is preferably a hydraulic rod, and the driving device 8 is preferably a rotary cylinder.

[0057] Specifically, firstly, the x-axis is adjusted by the moving component 1 301, so that the processing device 4 moves to the port position of the barrel part 2; then, the y-axis is adjusted by the moving component 2 302, so that the laser cladding head 401 and the lowest point inside the barrel part 2 are on the same straight line; finally, the z-axis is adjusted by the moving component 3 303, so as to realize the focus calibration process of the laser cladding head 401. Similarly, when calibrating the boring tool 402, repeating the above steps can realize the tool calibration of the boring process; of course, when the height needs to be adjusted during the tool calibration of the boring tool 402, the screwdriver can be used to cooperate with the bottom of the boring tool 402 to make fine adjustments, so as to complete the tool calibration step more conveniently and quickly. Finally, the processing device 4 can perform the composite processing process of laser cladding and boring on the barrel part 2 with the cooperation of the moving mechanism 3.

[0058] It should be noted that in the actual processing, since the processing device 4 at the end of the boring bar 6 is provided with a hydraulic rod, the inner groove size (D1) of the barrel 2 is limited, that is, it cannot be too small, and is generally required to be between 220mm and 500mm. At the same time, in order to avoid the feed port of the barrel 2, the size of the hydraulic rod (D2) is also limited, and it shall not be greater than 300mm.

[0059] In summary, compared with the conventional processing technology for the barrel member 2, the present application has the following advantages: 1. Improve processing efficiency: Composite processing equipment can complete multiple processing procedures at the same time, reducing the time for changing fixtures 7 and switching between processes, thereby improving the overall processing efficiency. 2.
