Description

Technical Field

[0001] This invention belongs to the field of additive manufacturing, specifically a carbon arc welding additive manufacturing coating forming device and method. Background Technology

[0002] In traditional carbon arc welding additive manufacturing coating processes, a carbon rod is used as an electrode to generate an electric arc between the carbon rod and the workpiece. The high temperature of the arc melts the filler material and the metal on the workpiece surface. The melted filler material accumulates on the workpiece surface, forming a coating. However, carbon rod replacement, substrate powder transportation, additive manufacturing, and the transfer of manufactured parts all require manual operation. Manual operation suffers from problems such as delayed responses, leading to prolonged process intervals and extended equipment downtime. Operators may also suffer burns from metal splatter or high-temperature arcs due to close contact with the equipment. The precision of carbon arc welded products depends heavily on the operator's skill level and experience. Manual adjustment of parameters such as carbon rod position and feed speed can result in positional deviations, and parameters such as welding current and welding voltage are dependent on the operator's experience and cannot be consistently stable, potentially leading to higher defect rates and increased rework costs. This purely manual operation model is no longer suitable for the current industrial requirements for safe and efficient production and urgently needs further improvement and innovation.

[0003] Traditional carbon rod replacement relies mainly on manual judgment. This can lead to unstable welding current and voltage if the carbon rod is replaced too late, or it can be replaced too early, wasting carbon rods. This not only affects the surface quality of the coating but also results in a material wastage rate as high as 15%-20%. This manual material management model leads to higher raw material costs, which contradicts the manufacturing industry's need for cost reduction and efficiency improvement.

[0004] 0004 Traditional carbon arc welding additive manufacturing coating equipment mostly uses fixed mechanical adjustment for parameter settings. When it is necessary to change to different specifications of substrates or adjust process parameters, multiple parameters such as carbon rod position and feeding speed need to be manually recalibrated, resulting in long changeover times and the possibility of the first product being unqualified due to adjustment errors. This low flexibility makes it difficult to adapt to the production needs of small batches and multiple varieties, so it is necessary to develop a molding device for mass production.

The carbon rods in the carbon rod storage box slide out from the gap below due to gravity because the bottom of the carbon rod storage box has a slope α. The gap is only the width of one carbon rod. The bottom of the carbon rod is then stuck into the square gap of the disc. The disc begins to rotate counterclockwise, rotating the carbon rod 90° to stand upright.

[0013] The workbench module of this invention includes a lifting platform module, a substrate pushing module, and a lifting platform cylindrical rod. The lifting platform module includes a lifting platform bottom end, a connecting rod assembly, moving wheels, a hydraulic push rod fixing rod, a hydraulic cylinder, a lifting platform top end, and a cylindrical fixing rod. The lifting platform bottom end is connected to the ground via the lifting platform cylindrical rod.

One end of the hydraulic cylinder is connected to the lifting platform bottom end via a bearing, and the other end is connected to the hydraulic push rod fixing rod via a hydraulic rod. The cylindrical fixing rod is connected to the connecting rod assembly via bearings and is limited in position.

[0014] The substrate pushing module includes a first fixed frame, a second fixed frame, a transmission rod, a servo motor, a crank assembly, and a pusher. The first fixed frame and the second fixed frame are connected to the top of the lifting platform by bolts. The transmission rod is connected to the first fixed frame and the second fixed frame by bearings. The servo motor is fixed to the second fixed frame by bolts. The crank assembly is fixed to the transmission rod at one end by a key and hinged at the other end by a bearing. The pusher is hinged to the bearing by bolts.

[0015] The conveyor belt module of the present invention includes a conveyor belt and a conveyor belt support, wherein the transmission belt is connected to the conveyor belt support and the conveyor belt support is connected to the ground.

[0016] A method for using a carbon arc welding additive manufacturing coating forming apparatus includes the following steps:

[0017] Step 1: Place the powder block and steel plate into the powder block placement rack and the substrate placement rack respectively, power on the entire device, start the equipment, and move the device to the preset working position;

[0018] Step 2: In the feeding module, the ball screw motor connected to the lifting frame of the substrate feeding module moves the nut of the ball screw to the highest plane where the steel plate is located. After moving to the target position, the electromagnet moves the middle and bottom of the linear platform towards the substrate placement frame through the linear platform motor and stops directly above the steel plate. Then, the electromagnet is energized, so that the electromagnet and the steel plate are magnetically connected. Then, the electromagnet moves the steel plate back to the initial state of the middle and bottom of the linear platform and moves towards the plane where the top of the lifting platform is located. After moving to the top plane of the lifting platform, the linear platform motor moves the middle and bottom of the linear platform laterally to directly above the steel plate. The electromagnet is de-energized, and the electromagnet and the steel plate separate. Then, the linear platform motor moves the middle and bottom of the linear platform back to the initial state to wait for the next additive manufacturing.

[0019] Step 3: The ball screw motor 2 connected to the lifting frame 2 of the powder block feeding module moves the ball screw 2 towards the highest plane where the powder block is located. After moving to the target position, the electromagnet 2 drives the linear platform middle section 2 and the linear platform bottom section 2 to move towards the powder block placement frame through the linear platform motor 2. It stops directly above the powder block. Then, the electromagnet 2 is energized, so that the electromagnet 2 and the powder block are connected together due to magnetism. Then, the electromagnet 2 drives the powder block back to the initial state of the linear platform middle section 2 and the linear platform bottom section 2, and moves towards the plane where the top of the lifting platform is located. After moving to the top plane of the lifting platform, the linear platform motor 2 drives the linear platform middle section 2 and the linear platform bottom section 2 to move laterally to directly above the top of the lifting platform. The electromagnet 2 is de-energized, and the electromagnet 2 and the powder block separate. Then, the linear platform motor 2 drives the linear platform middle section 2 and the linear platform bottom section 2 back to the initial state to wait for the next additive manufacturing.

[0020] Step 4: Due to the sloping bottom of the carbon rod storage box, the carbon rods in the storage box slide out from the gap below due to gravity. This gap is only the width of one carbon rod. The bottom of the carbon rod is then inserted into the square gap of the disc. The disc begins to rotate counterclockwise, rotating the carbon rod 90° to stand upright. During this process, the baffle is in a horizontal position to ensure that the carbon rod does not tilt to the sides while standing upright. The carbon rod is limited by the front and rear of the carbon rod storage box, the first bracket, and the baffle on both sides to ensure that the carbon rod does not tilt to the sides while standing upright. During this process, the bevel gear motor provides power to the bevel gear set, driving the disc on the second bracket to move. The cylindrical gear motor provides power to the first cylindrical gear set, driving the baffle on the first bracket to move.

[0021] Step 5: The square bracket 1 and connector 3 in the moving platform move in one direction controlled by the displacement platform on the welding gun head. The square bracket 2, connector 4, moving rod, cylindrical gear, and flexible rack use flexible rack transmission to control the movement of the welding gun head in one direction. When the carbon rod is in a vertical state, the welding gun head moves to directly above the carbon rod through the moving platform. It forms a device similar to a robotic arm through the clamp and the clamp on the bevel gear shaft 2 to hold the carbon rod for subsequent additive manufacturing operations. If an additive manufacturing operation has just ended, the welding gun head moves to directly above the carbon rod, one side of the clamp can hold the carbon rod, and the other side is directly above the waste bin. While holding the carbon rod, the used carbon rod waste falls into the waste bin by gravity.

[0022] Step 6: The welding torch head moves to the starting point directly above the powder block and steel plate to prepare for additive manufacturing. The hydraulic cylinder pushes the connecting rod assembly connected to the hydraulic push rod and fixed rod to move upward, driving the entire top of the lifting platform to move upward until it contacts the carbon rod and stops. When additive manufacturing begins, the lifting platform module will gradually move upward as the carbon rod is gradually consumed. After additive manufacturing is completed, the lifting platform module moves to a position horizontal with the conveyor belt. The two ends of the transmission rod are fixed by fixed frame one and fixed frame two. The servo motor rotates to drive the crank assembly to push the pusher forward and move the additively manufactured steel plate towards the conveyor belt module. After being pushed onto the conveyor belt, the servo motor rotates to return the pusher to the initial position, waiting for the next additive manufacturing.

[0023] Step 7: The pusher pushes the part onto the conveyor belt, and the additively manufactured part enters the next stage via the conveyor belt;

[0024] Step 8: Turn off the power.

[0025] The advantages of this invention compared to the prior art are:

[0026] 1. This invention adopts a fully integrated system of "automatic carbon rod changing + automatic feeding + automatic additive manufacturing + automatic transfer". Through the cooperation of each module, it can achieve a faster response time compared to manual processing. Moreover, the welded workpiece is seamlessly transferred by synchronous conveyor belt, and no manual intervention is required throughout the process. This design not only improves the processing efficiency of a single workpiece, but also completely avoids human contact with high-risk areas, fundamentally solving the efficiency bottleneck and safety pain points of traditional processes.

[0027] 2. This invention develops a carbon rod remaining length detection function to adapt to the carbon rod consumption and replacement mechanism. By monitoring the remaining length of the carbon rod in real time through the height of the lifting platform, the replacement program is automatically triggered when the remaining length is very low, ensuring the utilization rate of the carbon rod and achieving the purpose of efficient resource utilization and cost optimization.

[0028] 3. By incorporating process parameter templates for different workpieces, this invention calls different programs when processing different workpieces. The system can automatically adjust parameters such as the lifting speed of the lifting platform, the displacement distance during carbon rod additive manufacturing, welding current, and welding voltage. It also supports custom parameter saving, significantly improving the equipment's adaptability to multi-variety production.

[0029] This invention can be widely applied in fields such as additive manufacturing. Attached Figure Description

[0053] See Figure 14 The conveyor module 5 has the function of conveying the additively manufactured substrate and powder blocks out; it includes a conveyor belt 5-1 and a conveyor belt support 5-2, wherein the conveyor belt 5-1 is connected to the conveyor belt support 5-2, and the conveyor belt support 5-2 is connected to the ground.

[0054] 10. A method for using a carbon arc welding additive manufacturing coating forming apparatus as described in any one of claims 1 to 9, characterized in that it comprises the following steps:

[0055] Step 1: Place the powder block 1-2-12 and the steel plate 1-1-12 into the powder block placement rack 1-2-10 and the substrate placement rack 1-1-10 respectively. Power on the entire device, start the equipment, and move the device to the preset working position.

[0056] Step 2: In the feeding module 1, the ball screw motor 1-1-3, connected to the lifting frame 1-1-1 of the substrate feeding module 1-1, drives the nut of the ball screw 1-1-2 to move towards the highest plane where the steel plate 1-1-13 is located. After reaching the target position, the electromagnet 1-1-7, through the linear platform motor 1-1-9, drives the middle part 1-1-5 and the bottom part 1-1-6 of the linear platform to move towards the substrate placement frame 1-1-10, stopping directly above the steel plate 1-1-13. Then, the electromagnet 1-1-7 is energized, causing the electromagnet 1-1-7 and the steel plate 1-1-13 to be magnetically connected. Subsequently, the electromagnet 1-1-7 drives... Steel plate 1-1-13 returns to the initial state of the middle section 1-1-5 and the bottom section 1-1-6 of the linear platform, and moves towards the plane where the top section 4-1-6 of the lifting platform is located. After moving to the plane of the top section 4-1-6 of the lifting platform, the middle section 1-1-5 and the bottom section 1-1-6 of the linear platform are moved laterally by the linear platform motor 1-1-9 to directly above steel plate 1-1-13. Electromagnet 1-1-7 is de-energized, and electromagnet 1-1-7 separates from steel plate 1-1-13. Then, the linear platform motor 1-1-9 drives the middle section 1-1-5 and the bottom section 1-1-6 of the linear platform back to the initial state to wait for the next additive manufacturing.

[0057] Step 3: The ball screw motor 1-2-3, connected to the lifting frame 1-2-1 of the powder block feeding module 1-2, drives the ball screw 1-2-2 to move towards the highest plane where the powder block 1-2-13 is located. After reaching the target position, the electromagnet 1-2-7, through the linear platform motor 1-2-9, drives the middle part 1-2-5 and the bottom part 1-2-6 of the linear platform to move towards the powder block placement rack 1-2-10, stopping directly above the powder block 1-2-13. Then, the electromagnet 1-2-7 is energized, causing it to magnetically connect with the powder block 1-2-13. Subsequently, the electromagnet 1-2-7 drives the powder block 1-2-13... -2-13 returns to the initial state of the middle section 1-2-5 and the bottom section 1-2-6 of the linear platform, and moves towards the plane where the top section 4-1-6 of the lifting platform is located. After moving to the plane of the top section 4-1-6 of the lifting platform, the middle section 1-2-5 and the bottom section 1-2-6 of the linear platform are moved laterally by the linear platform motor 1-2-9 to directly above the top section 4-1-6 of the lifting platform. The electromagnet 1-2-7 is de-energized, and the electromagnet 1-2-7 and the powder block 1-2-13 separate. Then the linear platform motor 1-2-9 drives the middle section 1-2-5 and the bottom section 1-2-6 of the linear platform back to the initial state to wait for the next additive manufacturing.

[0058] Step 4: Because the bottom of carbon rod storage box 2-1 is sloped, carbon rod 2-2-1 slides out from the gap below due to gravity. This gap is only the width of one carbon rod 2-2-1. The bottom of carbon rod 2-2-1 then gets into the square gap of disc 2-2-2. Disc 2-2-2 begins to rotate counterclockwise, rotating carbon rod 2-2-1 90° to stand upright. During this process, the baffle 2-2-5 is in a horizontal position, ensuring that carbon rod 2-2-1 does not tilt to either side while standing upright. The carbon rod 2-2-1 is respectively limited by the carbon rod storage box 2-1, the bracket 2-2-4, and the baffle 2-2-5 on both sides, ensuring that the carbon rod 2-2-1 will not tilt on both sides during the upright process. During this process, the bevel gear motor 2-2-13 provides power to the bevel gear set 2-2-12, which drives the disc 2-2-2 on the bracket 2-2-10 to move. The cylindrical gear motor 2-2-11 provides power to the cylindrical gear set 2-2-6, which drives the baffle 2-2-5 on the bracket 2-2-4 to move.

[0059] Step 5: The square bracket 1 (3-1-4) and connector 3 (3-1-6) of the moving platform 3-1 move in one direction controlled by the displacement platform on the welding torch head 3-2. The square bracket 2 (3-1-5), connector 4 (3-1-8), moving rod 3-1-7, cylindrical gear 3-1-9, and flexible rack 3-1-10 use flexible rack and pinion transmission to control the movement of the welding torch head 3-2 in one direction. When the carbon rod 2-2-1 is in a vertical position, the welding torch head 3-2 moves to directly above the carbon rod via the moving platform 3-1. Fang, through the clamp 3-2-6 and the clamp on the bevel gear shaft 3-2-4, forms a device similar to a robotic arm, which clamps the carbon rod 2-2-1 for subsequent additive manufacturing operations. If an additive manufacturing operation has just ended, the welding gun head 3-2 moves to directly above the carbon rod 2-2-1, one side of the clamp can just hold the carbon rod 2-2-1, and the other side is directly above the waste bin 2-3. While clamping the carbon rod 2-2-1, the used carbon rod 2-2-1 waste material falls into the waste bin 2-3 by gravity.

[0060] Step 6: The welding torch head 3-2 moves to the starting point directly above the powder block 1-2-13 and the steel plate 1-1-13, ready to begin additive manufacturing. The hydraulic cylinder 4-1-5 pushes the connecting rod assembly 4-1-2 connected to the hydraulic push rod fixing rod 4-1-4 upward, driving the entire top of the lifting platform 4-1-6 upward until it contacts the carbon rod 2-2-1 and stops. During additive manufacturing, the lifting platform module 4-1 will gradually move upward as the carbon rod 2-2-1 is gradually consumed. After completion, the lifting platform module 4-1 moves to a horizontal position with the conveyor belt. The two ends of the transmission rod 4-2-3 are fixed by the first fixed frame 4-2-1 and the second fixed frame 4-2-2. The servo motor 4-2-4 rotates, driving the crank assembly 4-2-5 to push the pusher 4-2-6 forward, moving the additively manufactured steel plate 1-1-13 towards the conveyor belt module 5. After being pushed onto the conveyor belt, the servo motor 4-2-4 rotates, causing the pusher 4-2-6 to return to its initial position, waiting for the next additive manufacturing.

[0061] Step 7: Push the part from pusher 4-2-6 onto conveyor belt 5-1. The part after additive manufacturing enters the next stage via the conveyor belt. For example, the post-processing stage can eliminate coating stress, reduce the risk of deformation and cracking, and improve the mechanical properties of welds and heat-affected zones.

[0062] Step 8: Turn off the power.

[0063] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

10. A method for using a carbon arc welding additive manufacturing coating forming apparatus as described in any one of claims 1 to 9, characterized in that, Includes the following steps: Step 1: Place the powder block and steel plate into the powder block placement rack and the substrate placement rack respectively, power on the entire device, start the equipment, and move the device to the preset working position; Step 2: In the feeding module, the ball screw motor connected to the lifting frame of the substrate feeding module moves the nut of the ball screw to the highest plane where the steel plate is located. After moving to the target position, the electromagnet moves the middle and bottom of the linear platform towards the substrate placement frame through the linear platform motor and stops directly above the steel plate. Then, the electromagnet is energized, so that the electromagnet and the steel plate are magnetically connected. Then, the electromagnet moves the steel plate back to the initial state of the middle and bottom of the linear platform and moves towards the plane where the top of the lifting platform is located. After moving to the top plane of the lifting platform, the linear platform motor moves the middle and bottom of the linear platform laterally to directly above the steel plate. The electromagnet is de-energized, and the electromagnet and the steel plate separate. Then, the linear platform motor moves the middle and bottom of the linear platform back to the initial state to wait for the next additive manufacturing. Step 3: The ball screw motor 2 connected to the lifting frame 2 of the powder block feeding module moves the ball screw 2 towards the highest plane where the powder block is located. After moving to the target position, the electromagnet 2 drives the linear platform middle section 2 and the linear platform bottom section 2 to move towards the powder block placement frame through the linear platform motor 2. It stops directly above the powder block. Then, the electromagnet 2 is energized, so that the electromagnet 2 and the powder block are connected together due to magnetism. Then, the electromagnet 2 drives the powder block back to the initial state of the linear platform middle section 2 and the linear platform bottom section 2, and moves towards the plane where the top of the lifting platform is located. After moving to the top plane of the lifting platform, the linear platform motor 2 drives the linear platform middle section 2 and the linear platform bottom section 2 to move laterally to directly above the top of the lifting platform. The electromagnet 2 is de-energized, and the electromagnet 2 and the powder block separate. Then, the linear platform motor 2 drives the linear platform middle section 2 and the linear platform bottom section 2 back to the initial state to wait for the next additive manufacturing. Step 4: Due to the sloping bottom of the carbon rod storage box, the carbon rods in the storage box slide out from the gap below due to gravity. This gap is only the width of one carbon rod. The bottom of the carbon rod is then inserted into the square gap of the disc. The disc begins to rotate counterclockwise, rotating the carbon rod 90° to stand upright. During this process, the baffle is in a horizontal position to ensure that the carbon rod does not tilt to the sides while standing upright. The carbon rod is limited by the front and rear of the carbon rod storage box, the first bracket, and the baffle on both sides to ensure that the carbon rod does not tilt to the sides while standing upright. During this process, the bevel gear motor provides power to the bevel gear set, driving the disc on the second bracket to move. The cylindrical gear motor provides power to the first cylindrical gear set, driving the baffle on the first bracket to move. Step 5: The square bracket 1 and connector 3 in the moving platform move in one direction controlled by the displacement platform on the welding gun head. The square bracket 2, connector 4, moving rod, cylindrical gear, and flexible rack use flexible rack transmission to control the movement of the welding gun head in one direction. When the carbon rod is in a vertical state, the welding gun head moves to directly above the carbon rod through the moving platform. It forms a device similar to a robotic arm through the clamp and the clamp on the bevel gear shaft 2 to hold the carbon rod for subsequent additive manufacturing operations. If an additive manufacturing operation has just ended, the welding gun head moves to directly above the carbon rod, one side of the clamp can hold the carbon rod, and the other side is directly above the waste bin. While holding the carbon rod, the used carbon rod waste falls into the waste bin by gravity. Step 6: The welding torch head moves to the starting point directly above the powder block and steel plate to prepare for additive manufacturing. The hydraulic cylinder pushes the connecting rod assembly connected to the hydraulic push rod and fixed rod to move upward, driving the entire top of the lifting platform to move upward until it contacts the carbon rod and stops. When additive manufacturing begins, the lifting platform module will gradually move upward as the carbon rod is gradually consumed. After additive manufacturing is completed, the lifting platform module moves to a position horizontal with the conveyor belt. The two ends of the transmission rod are fixed by fixed frame one and fixed frame two. The servo motor rotates to drive the crank assembly to push the pusher forward and move the additively manufactured steel plate towards the conveyor belt module. After being pushed onto the conveyor belt, the servo motor rotates to return the pusher to the initial position, waiting for the next additive manufacturing. Step 7: The pusher pushes the part onto the conveyor belt, and the additively manufactured part enters the next stage via the conveyor belt; Step 8: Turn off the power.
