Description

Technical Field

[0001] The invention relates to the technical field of casting surface treatment, in particular to high-strength casting surface treatment equipment. Background Art

[0002] Castings are metal shaped objects obtained by various casting methods. That is, the smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods. After cooling and subsequent processing such as polishing, the resulting object has a certain shape, size and performance.

[0003] The existing workpieces formed by casting need to be treated with anti-rust treatment on their surfaces. Generally, anti-rust oil is applied to the surface of the casting. However, applying it with an ordinary brush will cause a large amount of anti-rust oil to be lost, and the application is uneven. The oiling efficiency of the oiling method with a brush is low, and the oiling operation cannot be performed quickly and continuously. There is also an oiling method in the prior art that atomizes the anti-rust oil and sprays it on the casting in an oiling chamber. Although this method can achieve continuous oiling operation with good uniformity, the anti-rust oil is easy to diffuse outward from the opening in the oiling chamber, resulting in waste of anti-rust oil and pollution of the working environment. The anti-rust oil cannot be recovered, and the flow direction of the anti-rust oil cannot be determined. The prior art lacks an oiling chamber that can automatically open the door when the casting enters and exits the oiling chamber and automatically close the door at other times.

[0031] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] like Figure 1-10The high-strength casting surface treatment equipment shown in the figure includes a horizontal conveying mechanism 1, a casting 2, an oiling chamber 3, an oiling mechanism 4, a steering mechanism 5 and a hoisting mechanism 6. The horizontal conveying mechanism 1 is arranged just above the oiling chamber 3. The length direction of the oiling chamber 3 is consistent with the transmission direction of the horizontal conveying mechanism 1. There are several hoisting mechanisms 6, and several hoisting mechanisms 6 are sequentially installed on the horizontal conveying mechanism 1. The oiling mechanism 4 is arranged in the oiling chamber 3. The steering mechanism 5 is installed at the top of the oiling chamber 3. It also includes a chamber door opening and closing mechanism 7. The top center of the oiling chamber 3 is provided with an avoidance groove 8 consistent with its length direction. Double doors 9 are provided at both ends of the oiling chamber 3 along the length direction. The chamber door opening and closing mechanism 7 is provided with two groups and is respectively located on the sides of the two double doors 9. The hoisting mechanism 6 includes It includes a lifting frame 10, a telescopic transmission rod 11 and a hook 12. The lifting frame 10 is fixedly installed on the horizontal transmission mechanism 1, the telescopic transmission rod 11 is installed on the lifting frame 10, and the hook 12 is fixedly installed on the bottom end of the telescopic transmission rod 11. The door opening and closing mechanism 7 includes a compression component 13, a wire transmission component 14 and a door closing reset component 15. There are several compression components 13 and they correspond one to one with several lifting mechanisms 6. The compression component 13 is connected to the wire transmission component 14 for transmission, and the wire transmission component 14 is connected to the double door 9 for transmission. The oiling chamber 3 is provided with a first limiting slide groove 16 for the double door 9 to slide. The door closing reset component 15 is fixedly installed on the lower half of the double door 9. The door closing reset component 15 is used to keep the double door 9 in a closed state when the double door 9 is not under force.

[0033] When the surface treatment equipment for high-strength castings 2 shown in the present invention is working, the castings 2 are transported to the inside of the oiling chamber 3 in sequence through the horizontal conveying mechanism 1 through several hoisting mechanisms 6 installed thereon, and the castings 2 installed on the hoisting mechanisms 6 are oiled by the oiling mechanism 4 in the oiling chamber 3. When the hoisting mechanism 6 moves inside the oiling chamber 3, the hoisting mechanism 6 is connected to the steering mechanism 5 located above the oiling chamber 3 through the hoisting mechanism 6, so that the hoisting mechanism 6 drives the castings 2 to rotate inside the oiling chamber 3, thereby achieving uniform oiling of the castings 2. When the hoisting mechanism 6 has not reached the oiling chamber 3, in order to ensure that the oil inside the oiling chamber 3 does not overflow through the entrance and exit of the oiling chamber 3, the two sets of double doors 9 located at the entrance and exit of the oiling chamber 3 are in a closed state, and the first limiting slide groove 16 is used to guide and limit the double doors 9. When the lifting mechanism 6 is carrying the casting 2 and is about to enter the oiling chamber 3, the compression component 13 in the chamber door opening and closing mechanism 7 outputs and drives the telescopic transmission rod 11 in the lifting mechanism 6 to move. At this time, the casting 2 mounted on the hook 12 is in a waiting state, and the compression component 13 drives the wire transmission component 14 connected thereto to move. The wire transmission component 14 overcomes the contraction force of the door closing reset component 15 to open the double doors 9 to both sides, so that the casting 2 mounted on the hook 12 can enter or move out of the oiling chamber 3. After the transmission is completed, the double doors 9 are reclosed by the door closing reset component 15 installed thereon, thereby ensuring that the double doors 9 are always in a closed state when the casting 2 has not arrived, that is, it can prevent oil from overflowing from the entrance and exit of the oiling chamber 3, thereby improving the utilization rate of oil, reducing pollution to the working environment, and reducing production costs.

[0034] The steering mechanism 5 includes a first mounting frame 17, a rotating gear 18 and a rack 19. The first mounting frame 17 is fixedly mounted on the top of the oil coating chamber 3. The first mounting frame 17 is located next to the avoidance groove 8. The rack 19 is horizontally fixedly mounted on the first mounting frame 17. The length direction of the rack 19 is consistent with the length direction of the oil coating chamber 3. There are several rotating gears 18, and the several rotating gears 18 correspond one-to-one to the several lifting mechanisms 6. The rotating gear 18 is horizontally fixedly mounted on the telescopic transmission rod 11, and the rotating gear 18 is engaged with the rack 19.

[0035] When the steering mechanism 5 is working, the hoisting mechanism 6 moves inside the oiling chamber 3, so that the rotating gear 18 installed on the telescopic transmission rod 11 moves along the transmission direction, that is, the rotating gear 18 moves to the meshing position with the rack 19 and moves on the rack 19. At this time, the meshing transmission of the rotating gear 18 and the rack 19 causes the telescopic transmission rod 11 to rotate around its own axis during displacement, thereby driving the hook 12 fixedly connected thereto to rotate synchronously, and then driving the casting 2 mounted on the hook 12 to rotate synchronously with the hook 12, that is, completing the function of driving the casting 2 to rotate in the oiling chamber 3, ensuring that the casting 2 can achieve uniform oiling operation in the oiling chamber 3, and ensuring the rust-proof effect of the casting 2. The first mounting bracket 17 is used to mount the rack 19 above the oiling chamber 3.

[0036] The telescopic transmission rod 11 includes a mounting sleeve 20 and a lifting rod 21. The lifting rod 21 can be raised and lowered and is arranged in the mounting sleeve 20. A vertical limit strip 22 is provided on the inner wall of the mounting sleeve 20. The lifting rod 21 is provided with a vertical limit groove 23 that slides with the vertical limit strip 22. The hook 12 is fixedly installed at the bottom end of the lifting rod 21, and the rotating gear 18 is fixedly installed on the outer wall of the mounting sleeve 20. The mounting sleeve 20 can be rotatably installed on the lifting frame 10 through a bearing.

[0037] When the telescopic transmission rod 11 moves, the lifting rod 21 can slide in the mounting sleeve 20 along the vertical direction, so that the compression assembly 13 drives the telescopic transmission rod 11 to move up and down. When the steering mechanism 5 is working, the mounting sleeve 20 fixed to it is driven to rotate by the rotating gear 18. The mounting sleeve 20 drives the lifting rod 21 to rotate synchronously with the mounting sleeve 20 through the vertical limit bar 22 and the vertical limit groove 23, thereby driving the hook 12 installed at the bottom of the lifting rod 21 to rotate, and then driving the casting 2 to rotate. When the lifting rod 21 is lifted or lowered in the mounting sleeve 20, its rotation function will not be affected, ensuring that the lifting and rotation processes do not interfere with each other.

[0038] The compression assembly 13 includes a transmission plate 24, a compression spring 25 and a limit block 26. The transmission plate 24 can be lifted and lowered and is arranged on the telescopic transmission rod 11. The compression spring 25 is sleeved on the telescopic transmission rod 11. One end of the compression spring 25 is fixedly connected to the top of the hanging frame 10, and the other end of the compression spring 25 is fixedly connected to the top of the transmission plate 24. The limit block 26 is fixedly mounted on one side of the transmission plate 24. A second limit slide 27 is vertically provided on the hanging frame 10. The transmission plate 24 is slidably connected through the second limit slide 27 and the limit block 26. The transmission plate 24 is horizontally fixedly mounted on the side wall of the upper half of the lifting rod 21. The lowest position of the lifting rod 21 is where the bottom of the transmission plate 24 is in contact with the top of the mounting sleeve 20. A limit guide rail 28 is provided below the horizontal transmission mechanism 1. The limit guide rail 28 is used to compress or relax the compression assembly 13, and the limit guide rail 28 is transmission-connected to the transmission plate 24.

[0039] The transmission plate 24 in the lifting mechanism 6 can be raised and lowered and is set in the lifting frame 10. The lifting and lowering of the transmission plate 24 are guided and limited by the limit block 26 and the second limit slide groove 27. The compression spring 25 pops the transmission plate 24 downward through the elastic force. When the transmission plate 24 moves, it drives the wire transmission assembly 14 connected to it to work, and then drives the double-opening door 9 connected to the wire transmission assembly 14 to open and close, so that the casting 2 can enter and exit the oil coating chamber 3. The transmission plate 24 realizes the change of position state through the limit guide rail 28, that is, the release and contraction of the compression spring 25.

[0040] The length direction of the limiting guide rail 28 is consistent with the length direction of the oil coating chamber 3. The limiting guide rail 28 includes an upper guide rail 29 and a lower guide rail 30. The upper guide rail 29 is a horizontal fixed rail. The lower guide rail 30 is composed of a first horizontal section 31, a first inclined section 32, a second horizontal section 33, a second inclined section 34 and a third horizontal section 35 along the running direction of the lifting mechanism 6. The end of the transmission plate 24 is in contact with the limiting guide rail 28. The transmission plate 24 is located between the upper guide rail 29 and the lower guide rail 30. The first inclined section 32 is inclined downward along the transmission direction of the casting 2. The height of the second horizontal section 33 is lower than the height of the first horizontal section 31. The first inclined section 32 is located in front of the entrance of the oil coating chamber 3. The inclination angle of the second inclined section 34 is symmetrical with the angle of the first inclined section 32 along the vertical plane. The height of the third horizontal section 35 is at the same horizontal position as the height of the first horizontal section 31.

[0041] The transmission plate 24 is located between the upper guide rail 29 and the lower guide rail 30. The upper guide rail 29 and the lower guide rail 30 limit the transmission plate 24 so that the transmission plate 24 is at the highest point. At this time, the compression spring 25 in the compression assembly 13 is in a compressed state. When the transmission plate 24 moves to the waiting state, the transmission plate 24 moves downward along the first inclined section 32 and gradually moves to the second horizontal section 33. When the transmission plate 24 is located at the horizontal fixed rail and the second horizontal section 33, the compression spring 25 is in a released state. During the release of the compression spring 25, the transmission plate 24 gradually moves downward, and the transmission plate 24 and the pull The wire transmission assembly 14 is connected for transmission, so that the wire transmission assembly 14 opens the double door 9 until the lifting mechanism 6 carries the casting 2 into the oiling chamber 3, and then closes the double door 9 through the door closing reset assembly 15. When the transmission plate 24 moves to the waiting-out state, the transmission plate 24 is located between the horizontal fixed rail and the second inclined section 34. At this time, the compression spring 25 is gradually compressed upward, and the transmission plate 24 gradually moves upward. The transmission plate 24 is connected for transmission with another set of wire transmission assemblies 14 to open the double door 9 on the other side, so that the lifting mechanism 6 can carry the casting 2 out of the oiling chamber 3, thereby completing the transmission function.

[0042] There are two groups of wire-drawing transmission components 14, and the two groups of wire-drawing transmission components 14 are symmetrically arranged on both sides of the oiling chamber 3 along the vertical center plane of the oiling chamber 3. The wire-drawing transmission components 14 include a first support frame 36, a second support frame 37, a first fixed pulley 38, a second fixed pulley 39, a steel rope 40 and a lifting plate 41. The first support frame 36 and the second support frame 37 are both fixedly mounted on the oiling chamber 3, and the first fixed pulley 38 and the second fixed pulley 39 are both rotatably arranged on the first support frame 36. The first fixed pulley 38 is located next to the double door 9, and the second fixed pulley 39 is located above the oiling chamber 3. The lifting plate 41 is provided with a plurality of wire-drawing transmission components 14, and the first fixed pulley 38 is located next to the double door 9. The second fixed pulley 39 is located above the oiling chamber 3. 1 is horizontally arranged, and the lifting plate 41 can be vertically slidably arranged on the second support frame 37. One end of the steel rope 40 is fixedly installed on one side of the double door 9, and the other end of the steel rope 40 passes through the first fixed pulley 38 and the second fixed pulley 39 in sequence and is fixedly connected to the lifting plate 41. The lifting plate 41 can be in contact with the transmission plate 24. The lifting plate 41 located at the entrance end of the oiling chamber 3 is arranged below the transmission plate 24, and the second fixed pulley 39 is located directly above the lifting plate 41. The lifting plate 41 located at the outlet end of the oiling chamber 3 is arranged above the transmission plate 24, and the second fixed pulley 39 is located directly below the lifting plate 41.

[0043] When the wire transmission assembly 14 is working, the first fixed pulley 38 and the second fixed pulley 39 are installed through the first support frame 36, and the steel rope 40 is installed on the first fixed pulley 38 and the second fixed pulley 39. The two ends of the steel rope 40 are fixedly connected to the side walls of the double-opening door 9 and the lifting plate 41 respectively. Since the length of the steel rope 40 is fixed, when the lifting plate 41 or the double-opening door 9 moves, it can drive the double-opening door 9 or the lifting plate 41 connected to the other end of the steel rope 40 to move, thereby realizing the transmission function of the movement. When the casting 2 enters the oiling chamber 3, the transmission plate 24 is located above the lifting plate 41, and the transmission plate 24 descends, driving the lifting plate 41 to descend synchronously, thereby realizing the transmission connection between the transmission plate 24 and the lifting plate 41. When the casting 2 leaves the oiling chamber 3, the transmission plate 24 is located below the lifting plate 41. At this time, the elastic force of the compression spring 25 drives the transmission plate 24 to move upward, and then drives the lifting plate 41 that is in contact with the transmission plate 24 to move upward synchronously, thereby realizing the transmission function.

[0044] The door closing reset assembly 15 includes a mounting plate 42, a two-way telescopic rod 43 and a reset spring 44. There are two mounting plates 42, and the two mounting plates 42 are fixedly mounted on the two ends of the double door 9 respectively. The two-way telescopic rod 43 is horizontally arranged between the two mounting plates 42, and the two ends of the two-way telescopic rod 43 are fixedly connected to the two mounting plates 42. There are two reset springs 44 and both are sleeved on the two-way telescopic rod 43. One end of the reset spring 44 is fixedly connected to the middle part of the two-way telescopic rod 43, and the other end of the reset spring 44 is fixedly connected to the mounting plate 42.

[0045] When the door closing reset assembly 15 is working, the mounting plate 42 is pulled by the reset spring 44, causing the bidirectional telescopic rod 43 to contract, and driving the double-opening door 9 fixedly connected to the mounting plate 42 to merge, completing the reset function. When the double-opening door 9 is reset, the lifting plate 41 is driven by the wire transmission assembly 14 to complete the reset, so that the subsequent compression assembly 13 can perform the transmission operation on it.

[0046] The oiling mechanism 4 includes an oil spray pipe 45, an oiling nozzle 46, an exhaust port 47, an exhaust pipe 48 and an exhaust pump. There are several oiling nozzles 46, which are installed on one side wall of the oiling chamber 3 along the length direction. Several oiling nozzles 46 are distributed on the oiling chamber 3 in a matrix. The oil spray pipe 45 is connected to the several oiling nozzles 46. The exhaust port 47 is located on the side of the oiling chamber 3 away from the oiling nozzle 46. One end of the exhaust pipe 48 is connected to the exhaust port 47, and the exhaust pump is installed on the exhaust pipe 48.

[0047] When the oiling mechanism 4 is working, the anti-rust oil is introduced into a plurality of oiling nozzles 46 through the oil spray pipe 45, and the anti-rust oil is evenly sprayed into the oiling chamber 3 through the oiling nozzles 46. The excess anti-rust oil is sucked into the exhaust pipe 48 through the exhaust port 47. The exhaust pump provides driving force for the oil extraction work, thereby determining the flow direction of the anti-rust oil in the oiling chamber 3. During the oiling operation, the casting 2 can be oiled more evenly, thereby improving the oiling effect.

[0048] The oiling mechanism 4 also includes an oil return pipe 49 and a cyclone separator 50. The cyclone separator 50 is installed on the side of the oiling chamber 3 close to the exhaust port 47. The exhaust pipe 48 is connected to the cyclone separator 50 on the side away from the exhaust port 47. The liquid outlet end of the cyclone separator 50 is connected to one end of the oil return pipe 49, and the other end of the oil return pipe 49 is connected to the oil outlet pipe.

[0049] The mixed gas of air and rust-proof oil in the exhaust pipe 48 is introduced into the cyclone separator 50, the separated air is directly discharged to the outside, and the separated rust-proof oil is reintroduced into the oil outlet pipe through the oil return pipe 49, thereby realizing the reuse of the rust-proof oil, improving the utilization rate of the rust-proof oil, and reducing the production cost.
