Description

Technical Field

[0001] The utility model relates to the technical field of hot-dip galvanizing equipment, in particular to a hot-dip galvanizing workpiece cooling and forming device. Background Art

[0002] Hot-dip galvanizing involves reacting molten metal with an iron substrate to create an alloy layer, thereby bonding the substrate and the coating. Hot-dip galvanizing involves first pickling the steel to remove iron oxide from the surface. After pickling, the steel is then cleaned in an aqueous solution of ammonium chloride, zinc chloride, or a mixture of ammonium chloride and zinc chloride before being placed in a hot-dip galvanizing tank. Hot-dip galvanizing offers advantages such as uniform coating, strong adhesion, and a long service life.

[0003] In order to achieve rust-proof effects on steel workpieces, the workpieces need to be hot-dip galvanized first. During the processing, hot-dip galvanizing requires high temperature to enable it to adhere to the steel workpiece. After the hot-dip galvanizing is completed, it needs to be cooled. The existing cooling device directly places the workpiece in the coolant and soaks it in water for cooling. Because the workpiece has just been hot-dip galvanized, the surface temperature of the workpiece is relatively high. Due to thermal expansion and contraction, when the temperature drops sharply, it is easy to cause the galvanized layer to be damaged, thereby affecting the forming effect and quality of the workpiece. Therefore, the application proposes a hot-dip galvanized workpiece cooling and forming device. Summary of the Invention

[0030] Example

[0031] like Figure 1 and Figure 2 As shown, the present invention proposes a hot-dip galvanized workpiece cooling and forming device, comprising a base plate 1, and a working pool 2 fixedly connected to the top of the base plate 1, a support column 3 fixedly installed on the top of the working pool 2, and four support columns 3 symmetrically installed on the upper end surface of the working pool 2, a chute 4 is installed on the top of the support column 3, and a chute 4 is provided on the top of every two support columns 3, and there are two chute 4 in total;

[0032] In addition, a moving device is provided in the chute 4, which includes a slider 13 slidably installed in the chute 4, and a screw rod 14 threadedly connected to the slider 13 is rotatably installed in the chute 4. The rotation of the screw rod 14 can make the slider 13 slide back and forth in the chute 4;

[0033] In addition, one end of the screw rod 14 passes through the outer wall of the slide 4, one end of one screw rod 14 is fixedly mounted with a driving wheel 15, and one end of the other screw rod 14 is fixedly mounted with a driven wheel 16, the driven wheel 16 and the driving wheel 15 are connected by a belt drive, and the driving wheel 15 is fixedly connected to the output shaft of the driving motor 17. When the driving motor 17 is started, the driving wheel 15 rotates, and the rotation of the driving wheel 15 causes the driven wheel 16 to rotate together, further causing the two screw rods 14 to rotate synchronously, so that the slider 13 can be adjusted and moved;

[0034] It is worth noting that it also includes a partition 5 fixedly installed between the inner walls of the working pool 2, a cooling trough 6 is provided on one side of the partition 5, and the cooling trough 6 is used to cool the hot-dip galvanized workpiece, and a galvanizing trough 7 is provided on the other side of the partition 5, and the galvanizing trough 7 is used for hot-dip galvanizing workpieces;

[0035] What is particularly important is that a slot 26 is provided on one side of the cooling trough 6, and a sealing baffle 27 is provided on the outer wall of the slot 26. The sealing baffle 27 is slidably installed on one side of the outer wall of the working pool 2, and a handle 28 is installed on the sealing baffle 27. Pulling the handle 28 makes the sealing baffle 27 slide left and right, thereby realizing the opening and closing of the cooling trough 6. An observation window is provided on the sealing baffle 27, which is convenient for staff to observe the cooling condition of the workpiece in the cooling trough 6.

[0036] like Figure 1-3 As shown, the device also includes a transport device, which is connected to the mobile device for automatic grabbing and adjusting the hot-dip galvanized workpiece. The transport device includes a support plate 8 fixedly mounted between two sliders 13. The sliding of the sliders 13 can drive the support plate 8 to move.

[0037] Furthermore, an electric telescopic rod 9 is provided at the bottom of the support plate 8, and the bottom end of the electric telescopic rod 9 is fixedly connected to a mounting plate 10. Two connecting rods 11 are fixedly installed at the bottom of the mounting plate 10. The connecting rods 11 are connected to fixing parts 12. The extension of the electric telescopic rod 9 drives the fixing parts 12 to descend, so that the fixing parts 12 fix and clamp the two ends of the workpiece. The material of the fixing parts 12 is made of high-temperature resistant material to ensure that the fixing parts 12 will not be deformed or damaged when fixing and clamping the hot-dip galvanized workpiece.

[0038] Furthermore, a rotating assembly is connected between the electric telescopic rod 9 and the support plate 8, and the rotating assembly includes a rotating shaft 18 rotatably installed at the bottom of the support plate 8, and a slow-speed motor 20 is fixedly installed on the top of the support plate 8.

The turntable 19 is fixedly connected to the electric telescopic rod 9. Starting the slow-speed motor 20 rotates the rotating shaft 18, and the rotation of the rotating shaft 18 drives the turntable 19 to rotate, so that the workpiece fixedly clamped by the fixing member 12 can be rotated and adjusted.

[0039] like Figure 2-4As shown, the device also includes a uniform cooling device, which is arranged in the cooling tank 6 for automatic uniform cooling of the hot-dip galvanized workpiece. The uniform cooling device includes a cooling box 21 fixedly installed on the outer wall of the working pool 2 on one side of the cooling tank 6. The cooling box 21 stores a coolant that supports the cooling and forming of the hot-dip galvanized workpiece. A cooling water pump 22 is fixedly installed on the top of the cooling box 21. A water pipe 23 is fixedly connected to the cooling water pump 22. The cooling water pump 22 can be used to pump the coolant in the cooling box 21 out and into the water pipe 23.

[0040] It is worth noting that the water pipe 23 is provided with multiple branch pipes 24, at least three of which are provided, and multiple groups of nozzles 25 are connected to the branch pipes 24, at least three of which are provided. The coolant discharged from the water pipe 23 passes through the branch pipes 24 and is finally evenly sprayed out by the nozzles 25. Under the rotation of the rotating shaft 18, the coolant can be evenly sprayed on each end face of the hot-dip galvanized workpiece, so that the hot-dip galvanized workpiece can be evenly cooled.

[0041] The working principle of this embodiment is as follows: the extension of the electric telescopic rod 9 drives the connecting rod 11 to move downward, so that the fixing member 12 can fix and clamp the two ends of the hot-dip galvanized workpiece in the galvanizing tank 7, and then the electric telescopic rod 9 is contracted to lift the fixed hot-dip galvanized workpiece, start the drive motor 17, and rotate the driving wheel 15. The driving wheel 15 rotates and drives the driven wheel 16 to rotate, so that the two screw rods 14 rotate synchronously, so that the slider 13 can drive the fixing member 12 to move to the left, and move the hot-dip galvanized workpiece into the cooling tank 6. When the hot-dip galvanized workpiece moves near the nozzle 25, the slow-speed motor 20 is started to rotate the rotating shaft 18. The rotation of the rotating shaft 18 drives the turntable 19 to rotate, so that the hot-dip galvanized workpiece can be rotated and adjusted, and the cooling water pump 22 is used to introduce the coolant from the cooling box 21 into the water guide pipe 23. Finally, the coolant is evenly sprayed on each end face of the hot-dip galvanized workpiece by the nozzle 25, thereby achieving uniform cooling of the hot-dip galvanized workpiece and avoiding the damage of the galvanized layer.

[0042] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
