Description

Technical Field

[0001] The invention belongs to the technical field of plasma cladding machines, in particular to a plasma cladding machine for processing corrosion-resistant and long-life aluminum profiles. Background Art

[0002] Plasma cladding machine is an advanced equipment that uses plasma beam as heat source to deposit materials or prepare coatings on metal surfaces. Its core principle is to melt alloy powder or other materials through high-temperature plasma and spray it onto the surface of the substrate to form a coating that is metallurgically bonded to the substrate, thereby significantly improving the substrate's wear resistance, corrosion resistance, high temperature resistance and other properties. Plasma cladding machine has significant advantages in the processing of corrosion-resistant and long-life aluminum profiles. It can improve its corrosion resistance and service life by forming a metallurgically bonded high-performance coating on the surface of the aluminum profile.

[0003] When processing profiles, some profiles have a large length and the cladding nozzle has a large moving span. Generally, the metal powder raw materials of the cladding nozzle are transported through a pneumatic pump and a plastic pipe. In traditional large-span transportation, the scattered plastic pipes may fold after the cladding nozzle moves a certain distance, resulting in powder blockage inside the pipe, thereby affecting the processing effect. Therefore, a plasma cladding machine for processing corrosion-resistant and long-life aluminum profiles is proposed. Summary of the Invention

[0007] Preferably, the top of the cladding nozzle is connected to one end of a powder conveying pipe, the powder conveying pipe penetrates the sliding seat from the side of the sliding seat and extends to the top of the sliding seat, and the powder conveying pipe passes through the inside of the limit baffle.

[0008] Preferably, the limit brackets are symmetrically distributed and a sliding plate is slidably connected in the middle of a pair of limit brackets. An opening is provided on one side of the sliding plate and the other side completely surrounds the outside of a limit bracket. A pair of elastic members are located inside the limit bracket and one end is fixedly connected to the vertical guide rail.

[0009] Preferably, the side of the sliding plate away from the elastic member 1 is fixedly connected to the limiting frame 1, the end of the limiting frame 1 away from the sliding plate is fixedly connected to the support block, the ends of the limiting brackets are fixedly connected to the limiting frame 2, and the support block and the middle of the limiting frame 2 are fixedly connected to the partition rod.

[0010] Preferably, the side of the limit frame 1 away from the sliding plate is vertical, the limit frame 1 corresponds to the limit frame 2 in position, and a powder conveying pipe passes through the inside of the limit frame 1 and the limit frame 2.

[0011] Preferably, the sliding block 1 and the traction rope are distributed in the middle of two groups of adjacent limit brackets, the sliding block 1 and the traction rope are located in the middle of a pair of adjacent limit brackets, and the pair of limit brackets belong to two groups of limit brackets respectively, and a limit ring is provided on the side of the limit bracket, and the sliding block 2 passes through the inside of the limit ring.

[0012] Preferably, the upper and lower ends of the traction rope are hinged with push plates, the ends of the push plates are hinged with baffles, the ends of the baffles away from each other are fixedly connected to elastic members 2, and the baffles are slidably connected to the limiting bracket.

The sliding plate slides along the limit bracket to pull the powder conveying pipe to be discharged in an S shape on the horizontal plane, thereby preventing the powder conveying pipe from naturally falling under the action of gravity, which may cause the powder conveying pipe to be squeezed and folded at the lowest point when the sliding seat moves, thereby ensuring smooth powder delivery inside the powder conveying pipe. The present invention cooperates with structures such as a limit assembly and an unlocking assembly to facilitate step-by-step unlocking of the sliding plate. As the sliding seat moves, the powder conveying pipe is gradually retracted. After the sliding plate in the middle of the limit bracket is pulled to a specified position by the elastic member 1, the sliding block 1 is squeezed, so that the sliding block 1 pulls the traction rope through the sliding block 2, and the pushing plate hinged to the traction rope flips and pushes the blocking rod, thereby causing the blocking rod to move up and down, thereby releasing the limit of the sliding plate, thereby achieving gradual retraction. The present invention facilitates the arrangement of the powder conveying pipes by arranging the cooperation of structures such as the limit baffle and the limit frame, and prevents the pair of powder conveying pipes from being entangled and knotted with each other through the support block and the dividing rod fixedly connected in the middle part of the limit frame. At the same time, the limit baffle limits the bending point of the powder conveying pipe to prevent the powder conveying pipe from being offset at this time, resulting in different degrees of retraction of the pair of powder conveying pipes, thereby avoiding the phenomenon of incomplete retraction of a single powder conveying pipe, which in turn causes bending and powder blockage.

DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] like Figures 1 to 7 As shown, the present invention provides a plasma cladding machine for processing corrosion-resistant and long-life aluminum profiles, comprising a fixed base 1, an aluminum profile workpiece 2 is mounted in the middle of the fixed base 1, a vertical guide rail 3 is provided on the side of the fixed base 1, a metal powder barrel 5 is provided on the side of the vertical guide rail 3, and a powder conveying pipe 6 is provided at the bottom of the metal powder barrel 5, and further comprising: A processing assembly 4 is mounted on the upper side of the vertical guide rail 3 and is used for performing cladding processing on the aluminum profile workpiece 2; A limiting assembly 7, which is installed on the side of the vertical guide rail 3 and is used to limit the powder conveying pipe 6; An unlocking assembly 8 is installed on the side of the limiting assembly 7 and is used to lock and unlock the limiting assembly 7; The limiting assembly 7 includes a plurality of limiting brackets 701 linearly distributed on the side of the vertical guide rail 3. One end of the limiting bracket 701 is slidably connected to a sliding plate 702. A pair of elastic members 703 are provided on one side of the sliding plate 702. The unlocking assembly 8 includes a sliding block 1 801 and a sliding block 2 803 slidably connected to the limiting bracket 701 , and a traction rope 802 is provided between the sliding block 1 801 and the sliding block 2 803 .

[0020] The above scheme is adopted: the aluminum profile workpiece 2 is processed by the cladding nozzle 405. At this time, metal powder is transported from the metal powder barrel 5 to the cladding nozzle 405 through the powder conveying pipe 6 by an external pneumatic pump. When the cladding nozzle 405 gradually moves toward one end of the metal powder barrel 5, the sliding plate 702, which is not restrained at this time, gradually pulls the loose powder conveying pipe 6 into the middle of the limiting bracket 701, so that the powder conveying pipe 6 remains in a horizontal state and folds in an S shape, so as to prevent the powder conveying pipe 6 from drooping downward due to the weight of the metal powder during transportation after it is relaxed, and then being squeezed and folded when the sliding seat 402 moves, resulting in powder blockage; After one sliding plate 702 moves to the end away from the limit frame 2 706, the sliding plate 702 squeezes the sliding block 1 801 to move, so that the sliding block 1 801 pulls the traction rope 802 to move through the sliding block 2 803. At this time, the traction rope 802 moves toward the side of the metal powder barrel 5, causing the push plates 804 on both sides of the traction rope 802 to flip, and the push plates 804 push the baffle 805 to move to the upper and lower sides, thereby releasing the restriction of the baffle 805 on the sliding plate 702, thereby unlocking the restriction of the adjacent sliding plate 702, so that the powder conveying pipe 6 can continue to be pulled into the middle of the limit bracket 701 for storage after it becomes loose, avoiding folding and reducing the risk of powder blockage.

[0021] like Figures 1 to 3 As shown, the processing component 4 includes a transverse guide rail 401 that slides with the vertical guide rail 3, a sliding seat 402 is slidably connected to the middle of the transverse guide rail 401, a transverse bracket 403 is fixedly connected to one side of the sliding seat 402, a gas pipeline 404 is installed in the middle of the transverse bracket 403, a cladding nozzle 405 is installed at the bottom of the gas pipeline 404, and a limiting baffle 406 is provided on the top of the sliding seat 402 and the top of the transverse bracket 403. The top of the cladding nozzle 405 is connected to one end of the powder conveying pipe 6, and the powder conveying pipe 6 penetrates the sliding seat 402 from the side of the sliding seat 402 and extends to the top of the sliding seat 402, and the powder conveying pipe 6 passes through the inside of the limiting baffle 406.

[0022] The above scheme is adopted: by setting up a processing component 4, the cladding nozzle 405 is driven by the transverse guide rail 401 and the sliding seat 402 to move for continuous operation, and the transverse bracket 403 is set to facilitate the installation of the cladding nozzle 405 directly above the aluminum profile workpiece 2. The gas pipeline 404 is used to transport fuel gas to the cladding nozzle 405 and to support the cladding nozzle 405. The design of the limit baffle 406 is used to limit the corners of the powder conveying pipe 6 to avoid offset and folding and powder blockage.

[0023] like Figures 4 to 6As shown, the limiting brackets 701 are symmetrically distributed and a sliding plate 702 is slidably connected in the middle of a pair of limiting brackets 701. An opening is provided on one side of the sliding plate 702 and the other side is completely surrounded by the outside of a limiting bracket 701. A pair of elastic members 703 are located inside the limiting bracket 701 and one end is fixedly connected to the vertical guide rail 3.

[0024] The above solution is adopted: by setting a limiting bracket 701 and a sliding plate 702, the sliding plate 702 slides along the limiting bracket 701, which can pull the powder conveying pipe 6 to perform S-shaped discharge on the horizontal plane, avoiding the powder conveying pipe 6 from naturally falling under the action of gravity, causing the powder conveying pipe 6 to be squeezed when the sliding seat 402 moves, resulting in folding at the lowest point, thereby blocking powder. The design of the elastic member 703 is used to pull the sliding plate 702 to move. At the same time, the design of a limiting bracket 701 that completely surrounds one side of the sliding plate 702 can be used to unlock the adjacent sliding plate 702.

[0025] like Figures 4 to 6 As shown, the side of the sliding plate 702 away from the elastic member 1 703 is fixedly connected to the limiting frame 1 704, and the end of the limiting frame 1 704 away from the sliding plate 702 is fixedly connected to the support block 705, and the ends of the limiting bracket 701 are fixedly connected to the limiting frame 2 706, and the middle parts of the support block 705 and the limiting frame 2 706 are fixedly connected to the dividing rod, and the side of the limiting frame 1 704 away from the sliding plate 702 is vertical, and the position of the limiting frame 1 704 corresponds to that of the limiting frame 2 706, and the powder conveying pipe 6 passes through the inside of the limiting frame 1 704 and the limiting frame 2 706.

[0026] The above scheme is adopted: the setting of limit frame 1 704 is used to pull the powder conveying pipe 6 to change its arrangement shape in the horizontal position, and the limit frame 1 704 is set to a vertical state toward the side of the support block 705, which can facilitate the pulling of the powder conveying pipe 6 to move, and at the same time cooperates with the support block 705 to support the bending point of the powder conveying pipe 6 at the support block 705, so that the powder conveying pipe 6 will not fold and block powder here. The design of limit frame 2 706 is used to limit and support the powder conveying pipe 6. Through the cooperation of limit frame 2 706 and limit frame 1 704, the powder conveying pipe 6 will not directly bend downward from the middle under the action of gravity, but will be supported by limit frame 2 706 and limit frame 1 704 at a section of the limit bracket 701, and metal powder is conveyed to the cladding nozzle 405 in a stepped arrangement to ensure conveying efficiency. The partition rod fixedly connected in the middle of the support block 705 and the limit frame 2 706 prevents a pair of powder conveying pipes 6 from entangled with each other and knotting.

[0027] like Figures 3 to 7As shown, sliding block 1 801 and traction rope 802 are distributed between two groups of adjacent limiting brackets 701, sliding block 1 801 and traction rope 802 are located between a pair of adjacent limiting brackets 701, and a pair of limiting brackets 701 belong to two groups of limiting brackets 701 respectively, and a limiting ring is set on the side of the limiting bracket 701, and sliding block 2 803 passes through the inside of the limiting ring.

[0028] The above solution is adopted: by setting the unlocking component 8 in the middle of the two groups of limit brackets 701, the sliding block 1 801 and the traction rope 802 are respectively fixed to a pair of adjacent limit brackets 701, so that the sliding plate 702 in the middle of a pair of limit brackets 701 is pulled to the specified position by the elastic member 1 703, which will squeeze the sliding block 1 801 to unlock the adjacent sliding plate 702. The limiting ring set on the side of the limit bracket 701 is used to limit the sliding block 2 803, so that the sliding block 2 803 remains in a straight state, and at the same time enables the sliding block 2 803 to directly pull the traction rope 802 along the direction of the limit bracket 701 to slide.

[0029] like Figures 4 to 7 As shown, the upper and lower ends of the traction rope 802 are hinged with a push plate 804, and the end of the push plate 804 is hinged with a baffle 805. The ends of the baffle 805 that are away from each other are fixedly connected with elastic parts 2 806. At the same time, the baffle 805 is slidably connected to the limiting bracket 701. The baffle 805 is located on the side of the sliding plate 702 close to the sliding block 1 801, and the baffle 805 is slidably connected to the limiting bracket 701, and the push plate 804 is tilted and closed toward the side away from the sliding block 1 801.

[0030] The above scheme is adopted: by setting a pushing plate 804 hinged to the traction rope 802, the blocking rod 805 can be pushed by flipping the pushing plate 804, so that the blocking rod 805 can move vertically to the upper and lower sides, thereby releasing the limit on the sliding plate 702, and setting the pushing plate 804 to be tilted and closed toward the side away from the sliding block 1 801, so that when the traction rope 802 slides toward the sliding block 1 801, it can drive the pushing plate 804 to flip and open, thereby pushing the blocking rod 805, and the elastic member 806 is designed to push the blocking rod 805 to reset and limit the blocking rod 805. The design of the blocking rod 805 is used to block the sliding plate 702 to keep the sliding plate 702 fixed.

[0031] like Figures 4 to 7 As shown, when the sliding plate 702 is pulled by the elastic member 1 703 until it collides with the sliding block 1 801, the sliding block 1 801 is squeezed by the sliding plate 702 through the sliding block 2 803 to drive the traction rope 802 to move, so that the traction rope 802 slides along the limiting bracket 701 toward the sliding block 1 801.

[0032] Using the above solution: when the sliding plate 702 is pulled by the elastic member 1 703 until it collides with the sliding block 1 801, the sliding block 1 801 is squeezed by the sliding plate 702 through the sliding block 2 803 to drive the traction rope 802 to move, so that the traction rope 802 slides along the limiting bracket 701 toward the sliding block 1 801.

[0033] The working principle and use process of the present invention are as follows: when in use, the aluminum profile workpiece 2 is fixed by the fixed base 1, and then the horizontal guide rail 401 slides vertically along the vertical guide rail 3, and the sliding seat 402 slides horizontally along the horizontal guide rail 401 to adjust the cladding nozzle 405, so that the cladding nozzle 405 moves to the side away from the metal powder barrel 5. Before this, the sliding plates 702 are pulled back one by one to be engaged with the blocking rod 805, so that the powder conveying pipe 6 in the middle of the limiting bracket 701 is released, and then the aluminum profile is clad by the cladding nozzle 405. The workpiece 2 is being processed. At this time, metal powder is transported from the metal powder barrel 5 to the cladding nozzle 405 through the powder conveying pipe 6 by an external pneumatic pump. When the cladding nozzle 405 gradually moves toward one end of the metal powder barrel 5, the sliding plate 702, which is not restrained at this time, gradually pulls the loose powder conveying pipe 6 into the middle of the limiting bracket 701, so that the powder conveying pipe 6 remains horizontal and folds in an S shape. This prevents the powder conveying pipe 6 from drooping downward due to the weight of the metal powder during transportation after it is relaxed, and then being squeezed and folded when the sliding seat 402 moves, causing powder blockage. After one sliding plate 702 moves to the end away from the limit frame 2 706, the sliding plate 702 squeezes the sliding block 1 801 to move, so that the sliding block 1 801 pulls the traction rope 802 to move through the sliding block 2 803. At this time, the traction rope 802 moves toward the side of the metal powder barrel 5, causing the push plates 804 on both sides of the traction rope 802 to flip, and the push plates 804 push the baffle 805 to move to the upper and lower sides, thereby releasing the restriction of the baffle 805 on the sliding plate 702, thereby unlocking the restriction of the adjacent sliding plate 702, so that the powder conveying pipe 6 can continue to be pulled into the middle of the limit bracket 701 for storage after it becomes loose, avoiding folding and reducing the risk of powder blockage.
