Through a chemical reaction, zinc is uniformly deposited on the metal surface to form a zinc-iron alloy coating. It has the advantages of uniform coating, strong adhesion, and high surface brightness.

[0003] Meanwhile, the application number is CN116695045B, "A hot-dip galvanizing treatment device for the surface of cast iron parts", which can improve the surface flatness of galvanized castings, thereby improving the effect and aesthetics of galvanizing, and on the other hand, prevent the surface of the castings from being affected by the accumulation of scum and slag; it can also prevent the surface of the castings from producing defects such as bubbles, holes or depressions, thereby improving the strength of the zinc layer on the surface of the galvanized castings and improving the quality of the zinc layer;

[0004] The above technical solution requires that the cast iron parts be placed inside the galvanizing box for hot-dip galvanizing during use. However, when the workpieces are taken out, they need to be taken out manually, which is not only troublesome but also causes certain harm to the workers.

[0005] Therefore, in response to the above problems, a hot-dip galvanizing treatment device for the surface of cast iron parts is proposed. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0024] like Figures 1 to 4 As shown, the utility model provides a hot-dip galvanizing treatment device for the surface of cast iron parts, comprising a galvanizing box 1, a controller 2 is fixedly connected to the outside of the galvanizing box 1, and a clamping and moving mechanism 3 is provided inside the galvanizing box 1;

[0025] The clamping and moving mechanism 3 includes a micro motor 31, the output end of the micro motor 31 is fixedly connected to a screw rod 32, the outer side of the screw rod 32 is threadedly connected to a ring 33, the outer side of the ring 33 is fixedly connected to a moving rod 34, a lifting groove 35 is opened in the inner wall of the galvanizing box 1, and the moving rod 34 is slidably connected to the inside of the lifting groove 35, the outer side of the moving rod 34 is fixedly connected to a connecting plate 36, the outer side of the connecting plate 36 is fixedly connected to a movable tube 37, the inner part of the movable tube 37 is rotatably connected to a rotating rod 38, the outer side of the rotating rod 38 is fixedly connected to a clamping frame 39, the top of the clamping frame 39 is fixedly connected to a threaded tube 310, the inner part of the threaded tube 310 is threadedly connected to a screw 311, and the bottom of the screw 311 is fixedly connected to a positioning rod 312.

[0026] Specifically, the micro motor 31 is symmetrically distributed on the top of the galvanizing box 1, the screw rod 32 is rotatably connected to the inside of the lifting groove 35, and the micro motor 31 is electrically connected to the controller 2. Therefore, the micro motor 31 can drive the screw rod 32 to rotate through the controller 2, and the screw rod 32 rotates in the inner wall of the galvanizing box 1.

[0027] like Figures 1 to 4As shown, the connecting plate 36 is slidably connected to the inner wall of the galvanizing box 1, and the clamping frame 39 is symmetrically distributed inside the galvanizing box 1. Since the moving rod 34 is slidably connected to the inside of the lifting groove 35, the ring 33 on the outside of the screw rod 32 can be limited. The connecting plate 36 moves on the inner wall of the galvanizing box 1, which can drive the clamping frame 39 to move inside the galvanizing box 1.

[0028] Furthermore, the threaded tube 310 is symmetrically distributed on the top of the clamping frame 39, and the positioning rod 312 is connected to the inside of the clamping frame 39 through the screw 311. The screw 311 rotates inside the threaded tube 310, so that the screw 311 drives the positioning rod 312 to position the workpiece inside the clamping frame 39.

[0029] like Figures 1 to 4 As shown, a toggle mechanism 4 is provided inside the galvanizing box 1, and the toggle mechanism 4 includes a motor 41. The output end of the motor 41 is fixedly connected to a rotating shaft 42, the outer side of the rotating shaft 42 is fixedly connected to a stabilizing cover 43, and the outer side of the stabilizing cover 43 is fixedly connected to a toggle rod 44.

[0030] It is worth noting that the motor 41 is fixedly connected to the outside of the galvanizing box 1, the shaft 42 is rotatably connected to the inside of the galvanizing box 1, and the controller 2 is electrically connected to the motor 41. Therefore, the motor 41 can be started by the controller 2, thereby causing the motor 41 to drive the shaft 42 to rotate.

[0031] like Figures 1 to 4 As shown, the toggle rods 44 are evenly distributed on the outside of the stabilizing cover 43, and the toggle rods 44 do not contact the inner bottom wall of the galvanizing box 1. The stabilizing cover 43 is driven to rotate by the rotating shaft 42, so that the stabilizing cover 43 drives the toggle rods 44 to intermittently toggle the workpiece.

[0032] The structure of the motor is prior art and will not be described in detail. Furthermore, the present invention also includes a power supply, a controller, and a switch, which are not the main technical points of this patent and will not be described in detail. The wiring diagram of the motor in this utility model is common knowledge in the field, and its operating principle is already known technology. The model is selected according to actual use, so the control method and wiring layout of the motor will not be explained in detail.

[0033] Working principle and process: By setting up the galvanizing box 1, when the workpiece needs to be galvanized, the workpiece is first placed inside the clamping frame 39, and the screw 311 is rotated inside the threaded tube 310, so that the screw 311 moves downward inside the threaded tube 310, and the screw 311 is used in conjunction with the positioning rod 312, so that the positioning rod 312 can clamp the workpiece inside the clamping frame 39. When the clamping is completed, the micro motor 31 is started by the controller 2, so that the micro motor 31 drives the screw rod 32 to rotate, and the rotation of the screw rod 32 drives the ring 33 to rotate. Since the outer side of the ring 33 is fixedly connected with the moving rod 34, and the moving rod 34 is slidably connected to the inside of the lifting groove 35, it can limit the ring 33. When the screw rod 32 rotates, The ferrule 33 can be moved downward on the outside of the screw rod 32. When the ferrule 33 moves, it can drive the connecting plate 36 to move on the inner wall of the galvanizing box 1, so that the clamping frame 39 drives the workpiece to move to the inside of the galvanizing box 1, achieving the effect of automatically placing the workpiece. When the galvanized workpiece needs to be taken out, the micro motor 31 drives the screw rod 32 to flip it. When the workpiece moves to the inside of the galvanizing box 1 through the clamping frame 39, the motor 41 is started to drive the motor 41 to rotate the rotating shaft 42, and the rotation of the rotating shaft 42 drives the toggle rod 44 on the outside of the stabilizing cover 43 to rotate. At this time, the toggle rod 44 will intermittently push the workpiece, so that the workpiece is rotated under the drive of the rotating rod 38, and then the workpiece can be fully in contact with the solvent inside the galvanizing box 1, thereby achieving the effect of improving the galvanizing efficiency.
