Description

Technical Field

[0001] The present invention relates to the field of non-ferrous metal production, and particularly to a surface anti-rust treatment device for non-ferrous metal production. Background Art

[0002] Surface anti-rust treatment for non-ferrous metal production refers to a process of taking a series of physical or chemical methods to prevent or delay the oxidation and corrosion of the surfaces of these metal materials during the manufacturing process of non-ferrous metals and their alloy products.

[0003] Existing anti-rust treatment methods usually involve coating anti-rust oil on metal workpieces for anti-rust treatment. However, since current anti-rust treatment equipment is often limited to a single treatment method and different equipment is required for anti-rust treatment, it is impossible to perform anti-rust treatment on different medium and small-sized and different tubular metal workpieces by means of oil immersion and oil spraying. This limits its adaptability to different types of metal workpieces and anti-rust requirements, and the use is not flexible enough.

[0004] Therefore, it is necessary to design a surface anti-rust treatment device for non-ferrous metal production that can perform anti-rust treatment on different medium and small-sized and different tubular metal workpieces by means of oil immersion and oil spraying, is convenient to adapt to different usage requirements, and has high flexibility in use. Summary of the Invention

[0005] In order to overcome the drawbacks that current anti-rust treatment equipment is often limited to a single treatment method, different equipment is required for anti-rust treatment, and it is impossible to perform anti-rust treatment on different medium and small-sized and different tubular metal workpieces by means of oil immersion and oil spraying, which limits its adaptability to different types of metal workpieces and anti-rust requirements and the use is not flexible enough, the present invention provides a surface anti-rust treatment device for non-ferrous metal production that can perform anti-rust treatment on different medium and small-sized and different tubular metal workpieces by means of oil immersion and oil spraying, is convenient to adapt to different usage requirements, and has high flexibility in use.

[0006] The technical implementation solution of the present invention is: A surface anti-rust treatment device for non-ferrous metal production, comprising a support base, a reserve pool, a loading mechanism, and a spraying mechanism. There are two support bases on the left and right. A reserve pool is connected between the support bases. Above the reserve pool, there is a loading mechanism capable of separately placing different medium and small-sized metal workpieces. On the reserve pool, there is a spraying mechanism capable of rotating and spraying oil on different tubular metal workpieces.

[0007] Further, the lower part of the reserve pool is of an arc-shaped structure.

[0008] Further, a sewage pipe is provided on the right side of the reserve pool.

[0009] Furthermore, the loading mechanism includes a mounting cover, a hydraulic cylinder, a mounting plate, an alignment frame, alignment guide rails, and a loading basket. The mounting cover is connected to the upper side of the reserve tank. Hydraulic cylinders are connected to the upper sides of both the left and right parts of the mounting cover. The telescopic ends of the hydraulic cylinders are connected to a mounting plate. Alignment frames are connected to both the front and rear sides of the mounting plate. Alignment guide rails are slidably clamped to the alignment frames. The loading basket is connected between the alignment guide rails. Different small and medium-sized metal workpieces are classified and placed in the loading basket. Then, the alignment guide rails are docked with the alignment frames, and the loading basket is pushed to move the alignment guide rails on the alignment frames to complete the installation of the loading basket. After the installation is completed, the hydraulic cylinders on the mounting cover are started to drive the mounting plate to move downward, causing the alignment frames and the loading basket to move downward.

[0010] Furthermore, a spraying mechanism is also included. The spraying mechanism includes a spraying pipe, a mounting seat, a mounting frame, connecting bolts, a rotating frame, a double-shaft motor, a rotating wheel, a driven wheel, a servo motor, a rotating roller, a cylinder, a connecting frame, and a driven roller. Two left and right spraying pipes are connected between the front and rear parts of the reserve tank and the mounting cover through pumps. Mounting seats are connected to both the left and right sides of the reserve tank. Mounting frames are placed on the upper sides of the mounting seats. Connecting bolts are connected to the lower sides of both the front and rear parts of the mounting frames. The connecting bolts all pass through the adjacent mounting seats, and nuts are threadedly provided on the connecting bolts. The nuts are all in contact with the adjacent mounting seats. There are two left and right rotating frames, and the rotating frames are all located in the middle of the adjacent mounting frames. Double-shaft motors are connected to the middle and lower parts of the rotating frames. Rotating wheels are connected to the output shafts on both the left and right parts of the double-shaft motors. The rotating wheels are all slidably connected to the adjacent mounting frames. Two left and right driven wheels are rotatably connected to both the front and rear parts of the rotating frames. The driven wheels are all slidably connected to the adjacent mounting frames. Servo motors are connected to the lower front parts of the rotating frames. Rotating rollers are connected to the output shafts of the servo motors. The rotating rollers are all rotatably connected to the adjacent rotating frames. Cylinders are connected to the middle and upper parts of the rotating frames. Connecting frames are connected to the telescopic ends of the cylinders. Driven rollers are rotatably connected to the connecting frames. The tubular metal workpiece is passed through the rotating frames so that the tubular metal workpiece is located between the rotating frames. The double-shaft motor is started to drive the rotating wheels to rotate, causing the rotating frames and the driven wheels to rotate, driving the tubular metal workpiece to rotate. At the same time, the servo motor is started to drive the rotating rollers to rotate, causing the tubular metal workpiece to move and the driven rollers to rotate. Then, the pump is started to spray the anti-rust oil in the reserve tank onto the tubular metal workpiece through the spraying pipe.

[0011] Furthermore, grooves are formed on both the rotating roller and the driven roller.

[0012] Furthermore, it also includes a jitter mechanism. The jitter mechanism includes a guide frame, a sliding plate, a clamping ring, a spring, a connecting plate, a connecting rod, and a guide member. Guide frames are connected to the upper sides of the left and right parts of the mounting plate. Sliding plates are slidably connected to the guide frames. Clamping rings are slidably connected to the lower parts of the sliding plates. The clamping rings are in contact with the loading basket. Two front and rear springs are connected between the left and right parts of the sliding plates and the adjacent guide frames. Connecting plates are connected to the upper parts of the sliding plates. Connecting rods are connected to the upper parts of the connecting plates. Guide members are connected to the upper sides of the left and right parts of the mounting cover. The connecting rods are slidably matched with the adjacent guide members. Start the hydraulic cylinder to drive the mounting plate to move downward, causing the loading basket to move downward, driving the guide frame and the connecting rod to move downward. When the connecting rod moves downward to a certain position, it will slide along the track on the guide member, causing the sliding plate to move left and right on the guide frame, deforming the spring, causing the clamping ring to move left and right, and further causing the loading basket to move left and right, so that the metal workpieces in the loading basket jitter in the rust preventive oil.

[0013] Furthermore, it also includes a cleaning mechanism. The cleaning mechanism includes a fixed seat, a rotating rod, and a blowing plate. Four fixed seats are connected to the upper sides of the left and right parts of the reserve pool, two in the front and two in the back. Rotating rods are rotatably connected to the fixed seats. Blowing plates are connected to the upper sides of the rotating rods. Rotate and adjust the blowing plate to drive the rotating rod to rotate on the fixed seat, making the blowing plate face the tubular metal workpiece. Gas is blown through the blowing plate onto the surface of the tubular metal workpiece. First, the impurities on the surface of the tubular metal workpiece are blown off by the blowing plate on the left, and then the anti-rust oil is sprayed through the spray pipe. When the tubular metal workpiece is driven to move to the right by the rotating roller and the driven roller, the excessive anti-rust oil sprayed on the tubular metal workpiece is blown off into the reserve pool by the blowing plate on the right.

[0014] Furthermore, it also includes a docking nozzle, and docking nozzles are connected to the upper parts of the blowing plates.

[0015] The present invention has the following advantages: 1. The present invention immerses different small and medium-sized metal workpieces through the loading mechanism and sprays different tubular metal workpieces through the spraying mechanism, achieving the effect of being able to perform anti-rust treatment on different small and medium-sized and different tubular metal workpieces through immersion and spraying, facilitating adaptation to different usage requirements and having a high usage flexibility.

[0016] 2. The present invention classifies different small and medium-sized metal workpieces and places them in the loading basket, then docks the alignment guide rail with the alignment frame, then pushes and installs the loading basket, and then starts the hydraulic cylinder to make the loading basket move downward, achieving the effect of being able to immerse different small and medium-sized metal workpieces separately after separation, avoiding direct contact between different workpieces resulting in scratches and damages, and improving the immersion uniformity.

[0017] 3. The present invention starts a dual-axis motor to drive a rotating wheel to rotate, driving a tubular metal workpiece to rotate. At the same time, a servo motor is started to drive a rotating roller to rotate, causing the tubular metal workpiece to move. Antirust oil is sprayed onto the tubular metal workpiece through a spray pipe, achieving the effect of being able to rotate and move different tubular metal workpieces for oil spraying, ensuring that the surfaces of the tubular metal workpieces are all covered by antirust oil, improving the uniformity of oil spraying, and enhancing the antirust effect.

[0018] 4. The present invention slides a connecting rod along a track on a guide member, causing a clamping ring to move left and right, making a loading basket move left and right, so that the metal workpieces in the loading basket shake in antirust oil, achieving the effect of being able to shake different small metal workpieces during oil immersion, promoting the flow of antirust oil at the same time, ensuring that every part of the metal workpieces is fully covered by antirust oil, and enhancing the antirust effect.

[0019] 5. The present invention rotates an adjustable blowing plate so that the blowing plate faces the metal workpiece. An air pipe is externally connected through a docking nozzle, and gas is blown through the blowing plate onto the surface of the metal workpiece, achieving the effect of being able to blow off impurities on the surface of the tubular metal workpiece before oil spraying and being able to blow off excess antirust oil after oil spraying, improving the adhesion between the antirust oil and the metal workpiece, enhancing the antirust effect, and avoiding waste of antirust oil.

Alignment guide rails 34 are slidably clamped on the alignment frames 33. A loading basket 35 is connected between the alignment guide rails 34.

[0036] As Figure 1 , Figure 5 , Figure 6 , Figure 7 and Figure 8 shown in the figure, it further includes a spraying mechanism 4. The spraying mechanism 4 includes a spray pipe 40, a mounting seat 41, a mounting frame 42, connecting bolts 421, a rotating frame 43, a double-shaft motor 44, rotating wheels 45, driven wheels 46, a servo motor 47, rotating rollers 48, a cylinder 49, a connecting frame 410, and a driven roller 411. Two left and right spray pipes 40 are connected between the front and rear parts of the reserve tank 2 and the mounting cover 30 through pumps. Mounting seats 41 are connected to the left and right sides of the reserve tank 2. Mounting frames 42 are placed on the upper sides of the mounting seats 41. Connecting bolts 421 are connected to the lower sides of the front and rear parts of the mounting frames 42. The connecting bolts 421 all pass through the adjacent mounting seats 41. Nuts are threadedly provided on the connecting bolts 421, and the nuts are all in contact with the adjacent mounting seats 41. There are two left and right rotating frames 43. The rotating frames 43 are all located in the middle of the adjacent mounting frames 42. Double-shaft motors 44 are connected to the middle and lower parts of the rotating frames 43. Rotating wheels 45 are connected to the output shafts of the left and right parts of the double-shaft motors 44. The rotating wheels 45 are all slidably connected to the adjacent mounting frames 42.

[0037] When using this device, first place the support base 1 in the surface rust prevention treatment area for non-ferrous metal production, then drain the rust preventive oil into the reserve tank 2, and then classify and place different small and medium-sized metal workpieces in the loading basket 35. Then dock the alignment guide rail 34 with the alignment frame 33, and then push the loading basket 35 to move the alignment guide rail 34 on the alignment frame 33 to complete the installation of the loading basket 35. After the installation is completed, start the hydraulic cylinder 31 on the installation cover 30 to drive the installation plate 32 to move downward, so that the alignment frame 33 and the loading basket 35 move downward, and then immerse the metal workpieces in the loading basket 35 in the rust preventive oil. Thus, it is possible to immerse the oil after separating and placing different small and medium-sized metal workpieces, avoiding scratches and damages caused by direct contact between different workpieces, improving the uniformity of oil immersion. When rust prevention treatment is required for tubular metal workpieces, the loading basket 35 can be moved outwards and taken out. Then, pass the connecting bolt 421 on the mounting bracket 42 through the mounting seat 41, and then dock the nut with the connecting bolt 421. Then rotate and tighten the nut. Next, pass the tubular metal workpiece through the rotating frame 43 so that the tubular metal workpiece is located between the rotating frames 43. Then start the cylinder 49 to drive the connecting frame 410 to move downward, so that the driven roller 411 contacts the rotating roller 48 with the tubular metal workpiece. Through the grooves provided on the rotating roller 48 and the driven roller 411, it is convenient to limit different tubular metal workpieces. Then start the double-shaft motor 44 to drive the rotating wheel 45 to rotate 180 degrees forward and backward, so that the rotating frame 43 and the driven wheel 46 rotate, driving the tubular metal workpiece to rotate 180 degrees forward and backward. At the same time, start the servo motor 47 to drive the rotating roller 48 to rotate, so that the tubular metal workpiece moves, and the driven roller 411 rotates. Then start the pump body so that the rust preventive oil in the reserve tank 2 is sprayed onto the tubular metal workpiece through the spray pipe 40. Thus, it is possible to rotate and move the oil spray for different tubular metal workpieces to ensure that the surfaces of the tubular metal workpieces are all covered with rust preventive oil, improving the uniformity of oil spraying and the rust prevention effect. After the treatment is completed, the rust preventive oil is discharged through the sewage pipe.

[0038] As Figure 1 , Figure 9 and Figure 10 shown, it also includes a shaking mechanism 5. The shaking mechanism 5 includes a guide frame 50, a sliding plate 51, a clamping ring 52, a spring 53, a connecting plate 54, a connecting rod 55 and a guide member 56. Guide frames 50 are connected to the upper sides of the left and right parts of the mounting plate 32. Sliding plates 51 are slidably connected to the guide frames 50. Clamping rings 52 are slidably connected to the lower parts of the sliding plates 51. The clamping rings 52 are all in contact with the loading basket 35. Two front and rear springs 53 are connected between the left and right parts of the sliding plates 51 and the adjacent guide frames 50. Connecting plates 54 are connected to the upper parts of the sliding plates 51. Connecting rods 55 are connected to the upper parts of the connecting plates 54. Guide members 56 are connected to the upper sides of the left and right parts of the mounting cover 30. The connecting rods 55 are slidably matched with the adjacent guide members 56.

[0039] When using the jitter mechanism 5 of this device, it can jitter different small and medium-sized metal workpieces during oil immersion. First, move the clamping ring 52 upward, then install the loading basket 35 containing the metal workpiece between the alignment frames 33 through the alignment guide rail 34. Then release the clamping ring 52. The clamping ring 52 moves downward under the action of gravity and contacts the loading basket 35 to limit the loading basket 35. Subsequently, start the hydraulic cylinder 31 to drive the mounting plate 32 to move downward, causing the loading basket 35 to move downward, driving the guide frame 50 and the connecting rod 55 to move downward. When the connecting rod 55 moves downward to a certain position, it will slide along the track on the guide member 56, causing the sliding plate 51 to move left and right on the guide frame 50, and the spring 53 deforms, causing the clamping ring 52 to move left and right, thereby causing the loading basket 35 to move left and right, so that the metal workpiece in the loading basket 35 jitters in the antirust oil, so as to be able to jitter different small metal workpieces during oil immersion, and at the same time promote the flow of the antirust oil, ensure that every part of the metal workpiece can be fully covered by the antirust oil, improve the antirust effect. When the loading basket 35 and the connecting rod 55 move downward to the limit position, the spring 53 resumes its original shape, and at the same time the sliding plate 51 also moves back to its original position.

[0040] As Figure 1 、 Figure 11 and Figure 12 As shown in the figure, it also includes a cleaning mechanism 6. The cleaning mechanism 6 includes a fixed seat 60, a rotating rod 61, a blowing plate 62 and a docking nozzle 63. Both the left and right upper sides of the reserve pool 2 are connected with two front and rear fixed seats 60. The fixed seats 60 are all rotatably connected with rotating rods 61. The upper sides of the rotating rods 61 are all connected with blowing plates 62. The upper parts of the blowing plates 62 are all connected with docking nozzles 63.

[0041] When using the cleaning mechanism 6 of this device, it can blow off the impurities and excess antirust oil on the surface of the tubular metal workpiece. Before spraying oil on the tubular metal workpiece, first rotate and adjust the blowing plate 62 to drive the rotating rod 61 to rotate on the fixed seat 60, so that the blowing plate 62 faces the tubular metal workpiece. Then connect an external air pipe through the docking nozzle 63, so that the gas blows towards the surface of the tubular metal workpiece through the blowing plate 62. First, the impurities on the surface of the tubular metal workpiece are blown off by the blowing plate 62 on the left, and then oil is sprayed through the spray pipe 40. When the tubular metal workpiece is driven to move to the right by the rotating roller 48 and the driven roller 411, the excess antirust oil on the tubular metal workpiece is blown off into the reserve pool 2 by the blowing plate 62 on the right, so as to be able to blow off the impurities on the surface of the tubular metal workpiece before spraying oil, and be able to blow off the excess antirust oil after spraying oil, improve the adhesion between the antirust oil and the metal workpiece, enhance the antirust effect, and avoid waste of the antirust oil.

When the hydraulic cylinder (31) is started to drive the mounting plate (32) to move downward, the loading basket (35) moves downward, driving the guide frame (50) and the connecting rod (55) to move downward. When the connecting rod (55) moves downward to a certain position, it slides along the track on the guide member (56), causing the sliding plate (51) to move left and right on the guide frame (50), deforming the spring (53), causing the clamping ring (52) to move left and right, and further causing the loading basket (35) to move left and right, so that the metal workpieces in the loading basket (35) shake in the rust preventive oil.

8. A surface anti-rust treatment device for non-ferrous metal production according to claim 1, characterized in that: It further includes a cleaning mechanism (6). The cleaning mechanism (6) includes a fixed seat (60), a rotating rod (61) and a blowing plate (62). Four fixed seats (60) are connected to the upper sides of the left and right parts of the reserve pool (2). Rotating rods (61) are rotatably connected to the fixed seats (60). Blowing plates (62) are connected to the upper sides of the rotating rods (61). By rotating and adjusting the blowing plate (62), the rotating rod (61) is driven to rotate on the fixed seat (60), so that the blowing plate (62) faces the tubular metal workpiece, and the gas is blown onto the surface of the tubular metal workpiece through the blowing plate (62). The impurities on the surface of the tubular metal workpiece are first blown off by the blowing plate (62) on the left, and then the rust preventive oil is sprayed through the spray pipe (40). When the tubular metal workpiece is driven to move rightward by the rotating roller (48) and the driven roller (411), the excessive rust preventive oil sprayed on the tubular metal workpiece is blown off into the reserve pool (2) by the blowing plate (62) on the right.

9. The surface rust prevention treatment equipment for non-ferrous metal production according to claim 8, characterized in that: It further includes a docking nozzle (63). Docking nozzles (63) are connected to the upper parts of the blowing plates (62).
