Description

Technical Field

[0001] The invention relates to the technical field of transmission shaft processing, in particular to a transmission shaft hot-dip galvanizing device and a method thereof. Background Art

[0002] Hot-dip galvanizing of the transmission shaft is to immerse the cleaned transmission shaft into molten zinc liquid through the wetting effect of the plating agent. In this process, the steel reacts with the molten zinc to form an alloyed film, namely the galvanized layer. This galvanized layer can effectively prevent the oxidation reaction caused by the transmission shaft contacting with air, water vapor, etc., thereby achieving a protective effect.

[0003] In the prior art, during the hot-dip galvanizing process, a layer of zinc ash and zinc slag will be formed on the surface of the zinc liquid. In order to prevent the zinc slag from adhering to the drive shaft and affecting the quality of the zinc coating, generally when the drive shaft is immersed in the zinc liquid and taken out of the zinc liquid, the staff is required to use a scraper to push away the zinc slag on the surface of the zinc liquid before taking it out.

[0014] A method for hot-dip galvanizing a transmission shaft, specifically comprising: S1. Adjust the gap between the fixed clamping plate and the movable clamping plate by rotating the corresponding adjusting bolts, and place the transmission shaft between the fixed clamping plate and the movable clamping plate and clamp them.

[0015] S2. Turn on the conveying motor to control the movement of the U-shaped slide and the connecting seat to convey the drive shaft. The drive shaft can move around the mounting frame and the guide rail. When the drive shaft moves to the top of the hot zinc liquid pool, it will be affected by the guide groove and the lifting guide rod and drop into the hot zinc liquid pool. Since the push plate is lower than the drive shaft, the push plate can first push away the zinc slag on the surface of the zinc liquid during the movement and descent process. Then the drive shaft is subsequently dropped and immersed in the zinc liquid in the hot zinc liquid pool to prevent the drive shaft from being attached to the zinc slag when entering the zinc liquid. At this time, close the transmission sprocket and wait for the drive shaft to be zinc dipped.

[0016] S3. After zinc dipping is completed, the transmission sprocket is reopened to transport the transmission shaft. During the process, it will rise again under the influence of the guide groove and the lifting guide rod. During the rising process, the push plate can push away the zinc slag that has re-attached to the surface of the zinc liquid. Then the transmission shaft rises along the path pushed by the push plate to avoid the transmission shaft being stuck with zinc slag during the process of taking it out of the zinc liquid.

[0017] S4. The transmission shaft that has been zinc-dipped will be transported to the top of the recovery bin, and with the movement of the U-shaped slide, the transmission shaft will be lowered into the recovery bin. At the same time, the linkage gear and the linkage rack will be engaged. During the continuous movement, the transmission shaft can rotate in the recovery bin, and the excess zinc liquid on the transmission shaft will be thrown into the recovery bin to prevent too much zinc liquid from adhering to the transmission shaft.

[0018] S5. When the linkage gear rotates, the scraper bar can scrape on one side of the push plate to scrape the zinc slag adhered to the push plate into the recovery bin to avoid affecting the subsequent use of the push plate.

[0019] S6. Turning on the auxiliary motor can make the fan blades rotate and blow air toward the transmission shaft to speed up the cooling of the transmission shaft. Finally, the continuously moving transmission shaft can be lifted and removed from the recovery bin. At this time, the transmission shaft can be removed to complete the zinc dipping operation.

[0020] Compared with the prior art, the present invention has the following beneficial effects: (1) According to the present invention, during zinc dipping, the transmission shaft can be placed on the fixed clamping plate for clamping and fixing, and then the conveying motor is turned on to convey the transmission shaft. During the conveying process, the push plate will first be driven to move and descend into the hot zinc liquid pool under the influence of the lifting guide rod and the guide groove, and the zinc slag on the surface of the zinc liquid in the hot zinc liquid pool will be pushed away. Then, the transmission shaft will descend into the hot zinc liquid pool along the path of the push plate pushing away the zinc slag. After the transmission shaft is immersed in zinc and rises under the action of the lifting guide rod and the guide groove, the push plate will first contact the zinc slag on the surface of the zinc liquid, and push away the zinc slag formed during the immersion process. Then, the effect of automatic slag pushing can be achieved during the process of immersing the transmission shaft in the zinc liquid and taking it out, thereby avoiding the adhesion of zinc slag on the transmission shaft. At the same time, the manual operation steps are omitted, saving manpower, making the zinc dipping process of the transmission shaft safer, and at the same time improving the efficiency of the zinc dipping process.

[0021] (2) The conveying motor can be used to convey the drive shaft to the recovery bin and lower the drive shaft into the recovery bin. At the same time, the linkage rack and the linkage gear will be meshed. At this time, the continuous movement of the U-shaped slide can drive the drive shaft to rotate, so that the excess zinc liquid on the surface of the drive shaft can be shaken off, and the excess or inadequately reacted zinc liquid attached to its surface can be removed, which helps to reduce the thickness difference of the galvanized layer. By turning on the auxiliary motor, the fan blades can rotate and blow air toward the drive shaft, accelerating the cooling speed of the drive shaft. As the drive shaft rotates, the wind can be evenly blown onto the drive shaft.

[0022] (3) When the lifting rod rotates, the scraper bar can move back and forth and scrape off the zinc slag attached to one side of the push plate, so that the zinc slag falls into the recovery bin for recycling and processing, while avoiding affecting the subsequent use of the push plate.

The moving U-shaped slide 41 will drive the guide wheels 45 on the inner wall to roll on the corresponding guide rail 4, and the continuously moving U-shaped slide 41 will drive the connecting seat 42 to move, so that the connecting seat 42 drives the mounting plate 5 to move through the lifting rod 44, and then the clamped transmission shaft 53 is conveyed.

[0028] Furthermore, a guide slide hole 46 is opened on the inner wall of the movable sleeve 43, and guide slide bars 47 are slidably installed in the two guide slide holes 46.

At this time, the transmission shaft 53 can be placed in the fixed clamps 51 on both sides, and then the adjusting bolts 54 are rotated in the opposite direction to move the movable clamp 52 to reset and clamp the transmission shaft 53.

[0030] Furthermore, the driving structure includes four conveying motors 61, and the four conveying motors 61 are all installed on the bottom side of the mounting frame 3. The output ends of the four conveying motors 61 pass through the mounting frame 3 and are respectively installed on four transmission sprockets 6.

[0031] Furthermore, the guide structure includes a guide groove 71, which is provided on the guide frame 7. A plurality of lifting guide rods 72 are movably installed in the guide groove 71.

When the lifting guide rod 72 moves to the top of the hot zinc liquid pool 2, the lifting guide rod 72 will move downward under the guidance of the guide groove 71 during the process, so that the descending lifting guide rod 72 drives the limiting collar 73 to descend.

The remaining features are the same as those in Example 1.

[0033] Example 3: Fig.11 In order to scrape off the zinc slag attached to the push plate 8 to avoid affecting its subsequent use, a scraping structure is arranged on the reciprocating slide 10, and the scraping structure includes a T-shaped guide bar 101, the T-shaped guide bar 101 is installed on one side of the push plate 8, the reciprocating slide 10 is slidably installed on the T-shaped guide bar 101, the push plate 8 is installed on the limiting collar 73, and a plurality of scraping strips 102 are installed on one side of the reciprocating slide 10, the scraping strip 102 is in contact with one side of the push plate 8, and the limiting collar 73 and the push plate 8 are both installed with a support seat 103, and the same rotating shaft 104 is rotatably installed on the two support seats 103, and a bevel gear 105 and a swing rod 107 are respectively installed at both ends of the rotating shaft 104, and a bevel gear ring 106 is installed on the lifting rod 44, and the bevel gear ring 106 is positioned at On the top side of the limiting collar 73, the conical gear ring 106 is meshed with the conical gear 105, and a linkage shaft 108 is provided on the reciprocating slide 10, in which a linkage hole 109 is movably installed, and the linkage hole 109 is installed on one side of the swing rod 107. The lifting rod 44 can drive the conical gear ring 106 to rotate during rotation, and the rotating conical gear ring 106 can drive the rotating shaft 104 to rotate by meshing with the conical gear 105, so that the swing rod 107 drives the reciprocating slide 10 to move horizontally back and forth, and the continuously moving reciprocating slide 10 will drive the scraper bar 102 to move back and forth on the surface of the push plate 8, so that the scraper bar 102 can scrape the zinc slag attached to the surface of the push plate 8 into the recovery bin 93 for recovery, and the other features are the same as those in Example 2.

[0034] A method for hot-dip galvanizing a transmission shaft, specifically comprising: S1. Adjust the gap between the fixed clamping plate 51 and the movable clamping plate 52 by rotating the corresponding adjusting bolt 54, and place the transmission shaft 53 between the fixed clamping plate 51 and the movable clamping plate 52 and clamp them.

[0035] S2. Turn on the conveying motor 61 to control the movement of the U-shaped slide 41 and the connecting seat 42 to convey the transmission shaft 53. The transmission shaft 53 can move around the mounting frame 3 and the guide rail 4. When the transmission shaft 53 moves to the top of the hot zinc liquid pool 2, it will be affected by the guide groove 71 and the lifting guide rod 72 and drop into the hot zinc liquid pool 2. Since the push plate 8 is lower than the transmission shaft 53, the push plate 8 can first push away the zinc slag on the surface of the zinc liquid during the movement and descent process. Then the transmission shaft 53 is subsequently dropped and immersed in the zinc liquid in the hot zinc liquid pool 2 to prevent the transmission shaft 53 from being attached to the zinc slag when entering the zinc liquid. At this time, close the transmission sprocket 6 and wait for the zinc immersion of the transmission shaft 53 to be completed.

[0036] S3. After the zinc dipping is completed, the transmission sprocket 6 is reopened to transport the transmission shaft 53. During the process, it will rise again under the influence of the guide groove 71 and the lifting guide rod 72. The push plate 8 can push away the zinc slag re-attached to the surface of the zinc liquid during the rising process. Then the transmission shaft 53 rises along the path pushed by the push plate 8 to prevent the transmission shaft 53 from being stuck with zinc slag during the process of being taken out of the zinc liquid.

[0037] S4. The transmission shaft 53 that has been zinc-dipped will be transported to the top of the recovery bin 93, and with the movement of the U-shaped slide 41, the transmission shaft 53 will be lowered into the recovery bin 93, and at the same time, the linkage gear 92 will be meshed with the linkage rack 91. During the continuous movement, the transmission shaft 53 can be rotated in the recovery bin 93, and the excess zinc liquid on the transmission shaft 53 will be thrown into the recovery bin 93 to prevent too much zinc liquid from adhering to the transmission shaft 53.

[0038] S5. When the linkage gear 92 rotates, the scraper bar 102 can scrape on one side of the push plate 8 to scrape the zinc slag adhered to the push plate 8 into the recovery bin 93 to avoid affecting the subsequent use of the push plate 8.

[0039] S6. Turning on the auxiliary motor 96 can rotate the fan blades 97 to blow air toward the transmission shaft 53, thereby accelerating the cooling speed of the transmission shaft 53. Finally, the continuously moving transmission shaft 53 can be lifted and removed from the recovery bin 93. At this time, the transmission shaft 53 can be removed to complete the zinc dipping operation.

[0040] The working principle is as follows: by rotating the two adjusting bolts 54 at the corresponding positions, the two adjusting bolts 54 can be moved by cooperating with the threads of the mounting plate 5, so that the rotating and moving adjusting bolts 54 drive the movable clamping plate 52 to slide on the inner wall of the fixed clamping plate 51, so that the space on the inner wall of the fixed clamping plate 51 becomes larger. At this time, the transmission shaft 53 can be placed in the fixed clamping plates 51 on both sides, and then the adjusting bolts 54 are rotated in the opposite direction to move the movable clamping plate 52 to reset. The reset movable clamping plate 52 can clamp the transmission shaft 53 to prevent the transmission shaft 53 from loosening during transportation. Then, the conveying motor 61 under the mounting frame 3 is turned on, and the output end of the conveying motor 61 can drive the transmission sprocket 6 to rotate. Through the transmission cooperation between the transmission sprocket 6 and the transmission chain 62, the transmission chain 6 2 can perform circular motion around the mounting frame 3. During the process, the transmission chain 62 can drive the U-shaped slide 41 to move. The moving U-shaped slide 41 will drive the guide wheel 45 of the inner wall to roll on the corresponding guide rail 4. By arranging the guide wheels 45 on both sides of the guide rail 4, the U-shaped slide 41 can be prevented from falling off the guide rail 4 and the mounting frame 3, and the moving direction of the U-shaped slide 41 can be limited. The continuously moving U-shaped slide 41 will drive the connecting seat 42 to move, so that the connecting seat 42 drives the mounting plate 5 to move through the lifting rod 44, thereby conveying the clamped transmission shaft 53. In the process of the movement of the lifting rod 44, the lifting guide rod 72 can be driven to move in the guide groove 71 on the guide frame 7 through the limiting collar 73. By arranging the limiting baffle 74 and the guide The lifting rod 44 is fitted with the frame 7, which can prevent the limit ring 73 from rotating during the movement of the lifting rod 44. When the lifting guide rod 72 moves to the top of the hot zinc liquid pool 2, the lifting guide rod 72 will move downward under the guidance of the guide groove 71, so that the descending lifting guide rod 72 drives the limit ring 73 to descend, and the limit ring 73 drives the lifting rod 44 to descend by cooperating with the limit ring 75. During the descent of the lifting rod 44, it can drive the guide slides 47 on both sides to slide in the two guide slide holes 46 on the movable sleeve 43 respectively. At the same time, the lifting rod 44 will slide on the inner wall of the linkage gear 92. The continuously descending lifting rod 44 will drive the mounting plate 5 and the clamped transmission shaft 53 to descend, and the limit ring 73 will drive the push plate 8 to descend. Since the push plate 8 is at a lower position than the transmission shaft 53, the push plate 8 will first contact the hot zinc liquid in the hot zinc liquid pool 2 during the descent process, and the push plate 8 can be driven by the cooperation of the U-shaped slide 41 and the lifting guide rod 72 while being lowered into the hot zinc liquid and moving horizontally, so that the zinc slag on the surface of the zinc liquid can be pushed away, and the transmission shaft 53 can be prevented from sticking to the zinc slag when it descends into the zinc liquid. When the transmission shaft 53 is completely immersed in the zinc liquid, the transmission of the transmission shaft 53 can be stopped by turning off the conveying motor 61, so that it is immersed in the zinc liquid. After the zinc immersion operation is completed, the conveying motor 61 is reopened, and at this time, the continuous lifting guide rod 72 will be guided by the guide groove 71 again and rise during the continuous movement, so that the push plate 8 moves horizontally and rises in the zinc liquid.The zinc slag gathered again on the surface of the zinc liquid is pushed away, and then the transmission shaft 53 rises, thereby preventing the transmission shaft 53 from contacting the zinc slag during the process of immersing in the zinc liquid or taking out from the zinc liquid.

[0041] After the transmission shaft 53 is dipped in hot zinc, the movement of the transmission chain 62 can drive it to move to the top of the recovery bin 93, and then under the guidance of the guide groove 71 and the guide frame 7, the transmission shaft 53 is lowered into the recovery bin 93. At the same time, the connecting seat 42 will drive the linkage gear 92 to engage with the linkage rack 91 on the L-shaped support plate 9 during the continuous movement, and the continuous movement of the connecting seat 42 will cause the linkage gear 92 to rotate by engaging with the linkage rack 91. The rotating linkage gear 92 can drive the movable sleeve 43 to rotate, so that the movable sleeve 43 rotates on the limiting ring 99 on the inner wall of the connecting seat 42 through the annular groove 98, thereby preventing the movable sleeve 43 from falling off from the connecting seat 42 during the rotation. The continuously rotating movable sleeve 43 can drive the lifting rod 44 to rotate through the cooperation of the guide sliding hole 46 and the guide sliding strip 47. The rotating lifting rod 44 will drive the limiting ring 75 to rotate on the inner wall of the limiting sleeve 73, so that the limiting sleeve 73 will not interfere with the rotation of the lifting rod 44. The continuously rotating lifting rod 44 can drive the mounting plate 5 to rotate, thereby driving the clamped transmission shaft 53 to rotate, and the excess zinc liquid on the transmission shaft 53 is thrown into the recovery bin 93. In addition, the auxiliary motor 96 can be turned on during the movement of the transmission shaft 53. The output end of the auxiliary motor 96 will drive the fan blades 97 to rotate, so that the fan blades 97 blow air toward the transmission shaft 53, and the auxiliary transmission shaft 53 is quickly cooled down.

[0042] During the rotation of the lifting rod 44, the conical gear ring 106 can be driven to rotate. The rotating conical gear ring 106 can drive the rotating shaft 104 to rotate on the two support seats 103 by meshing with the conical gear 105. The continuously rotating rotating shaft 104 can drive the swing rod 107 to rotate, so that the swing rod 107 drives the linkage hole 109 to perform circular motion. The circular motion linkage hole 109 will move in the linkage shaft 108, and drive the reciprocating slide 10 to perform horizontal reciprocating movement through cooperation with the linkage shaft 108. The reciprocating reciprocating slide 10 will slide on the T-shaped guide strip 101, thereby limiting the moving direction of the reciprocating slide 10. The continuously moving reciprocating slide 10 will drive the scraper bar 102 to reciprocate on the surface of the push plate 8, so that the scraper bar 102 can scrape the zinc slag attached to the surface of the push plate 8 into the recovery bin 93 for recovery.

10. A method for hot-dip galvanizing a transmission shaft according to claim 1, specifically comprising: S1. The gap between the fixed clamping plate (51) and the movable clamping plate (52) is adjusted by rotating the corresponding adjusting bolt (54), and the transmission shaft (53) is placed between the fixed clamping plate (51) and the movable clamping plate (52) and clamped; S2, start the conveying motor (61) to control the movement of the U-shaped slide (41) and the connecting seat (42), and convey the transmission shaft (53). The transmission shaft (53) can move around the mounting frame (3) and the guide rail (4). When the transmission shaft (53) moves to the top of the hot zinc liquid pool (2), it will be affected by the guide groove (71) and the lifting guide rod (72) and fall into the hot zinc liquid pool (2). Since the push plate (8) is lower than the transmission shaft (53), the push plate (8) can first push away the zinc slag on the surface of the zinc liquid during the movement and descent process, and then the transmission shaft (53) will subsequently fall and be immersed in the zinc liquid in the hot zinc liquid pool (2) to prevent the transmission shaft (53) from being attached to the zinc slag when entering the zinc liquid. At this time, close the transmission sprocket (6) and wait for the transmission shaft (53) to be immersed in zinc; S3. After the zinc dipping is completed, the transmission sprocket (6) is reopened to transport the transmission shaft (53). During the process, the transmission shaft (53) is again affected by the guide groove (71) and the lifting guide rod (72) to rise. During the rising process, the push plate (8) can push away the zinc slag that has reattached to the surface of the zinc liquid. Then, the transmission shaft (53) rises along the path pushed away by the push plate (8), thereby preventing the transmission shaft (53) from being attached to the zinc slag during the process of being taken out of the zinc liquid. S4. The transmission shaft (53) that has been zinc-dipped is transported to the top of the recovery bin (93), and as the U-shaped slide (41) moves, the transmission shaft (53) is lowered into the recovery bin (93), and the linkage gear (92) is meshed with the linkage rack (91). During the continuous movement, the transmission shaft (53) is rotated in the recovery bin (93), and the excess zinc liquid on the transmission shaft (53) is thrown into the recovery bin (93), so as to prevent the excessive zinc liquid from adhering to the transmission shaft (53); S5, the linkage gear (92) rotates while the scraper (102) scrapes on one side of the push plate (8), so as to scrape the zinc slag adhered to the push plate (8) into the recovery bin (93), so as to avoid affecting the subsequent use of the push plate (8); S6, turning on the auxiliary motor (96) can cause the fan blade (97) to rotate, blowing air toward the transmission shaft (53), accelerating the cooling speed of the transmission shaft (53), and finally the continuously moving transmission shaft (53) can be lifted and removed from the recovery bin (93), at which time the transmission shaft (53) can be removed, completing the zinc dipping operation.
