Description

Technical Field

[0001] This utility model relates to the field of screw manufacturing technology, and more specifically, to a surface treatment mechanism for the production and processing of self-tapping screws. Background Technology

[0002] Self-tapping screws, also known as quick-thread screws, are quick-installing fasteners made of steel with a passivated galvanized surface. They are primarily used for connecting thin metal sheets (steel plates, saw blades, etc.). The connection process involves first drilling a threaded hole in the parts to be connected, and then screwing the self-tapping screw into the threaded hole.

[0003] Based on the above, the inventors have discovered that self-tapping screws require surface treatment during the production and processing process. However, due to incomplete contact between the self-tapping screw and the chemical agent, repeated immersion may occur after prolonged use, resulting in a waste of human resources. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a surface treatment mechanism for the production and processing of self-tapping screws, aiming to achieve a more practical purpose.

It can achieve full contact between the self-tapping screws and chemical reagents, and at the same time dry the self-tapping screws, so as to avoid the phenomenon of chemical reagents entering the outside of the device and causing environmental pollution.

[0006] 2. Technical Solution

[0014] 3. Beneficial effects

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] (1) In this solution, by setting up a placement box, the operator pours the chemical solution into the bottom of the box, starts the hydraulic cylinder to move the placement box downwards, so that the four connecting blocks are engaged in the four grooves, starts the servo motor to drive the fixed plate to rotate, so that the placement box can rotate, which can rotate the self-tapping screws inside the placement box, so that the chemical solution and the self-tapping screws can be in full contact, thereby improving the surface treatment effect.

[0017] (2) In this scheme, by setting up an air supply pipe, two air pumps are set on both sides of the box. The air pumps supply air to the air inlet pipe, and the center is dried through several air outlet pipes inside the air supply pipe. The hydraulic cylinder is started to move the placement box upward, thereby drying the self-tapping screws inside the placement box, avoiding the chemical agents being carried outside the device with the self-tapping screws, thus polluting the environment.

[0026] Example:

[0027] Please see Figures 1-5 A surface treatment mechanism for self-tapping screw production includes a housing 1. A fixing frame 2 is fixedly welded to the top of the housing 1. A hydraulic cylinder 3 is fixedly connected to the center of the top of the fixing frame 2. Air pumps 4 are fixedly connected to both sides of the housing 1. A fixing rod 5 is provided at the bottom of the telescopic shaft of the hydraulic cylinder 3. A placement box 6 is fixedly connected to the bottom of the fixing rod 5. An air supply pipe 7 is fixedly connected to the inner wall of the housing 1. Several air outlet pipes 8 are provided on the inner side of the air supply pipe 7. A servo motor 9 is fixedly welded to the center of the bottom of the housing 1. A sliding groove 10 is opened at the top of the fixing rod 5. A protrusion 11 is fixedly connected to the bottom of the telescopic shaft of the hydraulic cylinder 3. Air inlet pipes 12 are fixedly connected to both sides of the air supply pipe 7. The output end of the servo motor 9 is driven to a fixing plate 13 through a coupling. Four grooves 14 are opened at the top of the fixing plate 13. Four connecting blocks 15 are fixedly connected to the center of the bottom of the placement box 6. A mesh frame is provided at the lower end of the placement box 6 to facilitate contact between chemical agents and self-tapping screws. It is highly practical.

[0028] See Figure 2 , Figure 3 The bottom of the box 1 is provided with a drain pipe, and the drain pipe is equipped with a control valve. The lower end of the placement box 6 is provided with a mesh frame, and the protrusion 11 is rotatably connected to the inside of the slide groove 10. When the placement box 6 rotates, the protrusion 11 is slidably connected to the inside of the slide groove 10, which facilitates the rotation of the placement box 6 and allows the self-tapping screws inside to better contact the chemical reagents.

[0029] See Figure 4The air inlet ends of the two air pumps 4 are fixedly connected to the outside of the two air inlet pipes 12 respectively. The inner sides of several air outlet pipes 8 are respectively set with gaps to the outside of the placement box 6. Two air pumps 4 are set on both sides of the box 1. The air pumps 4 supply air to the air inlet pipes 12. The center is dried through several air outlet pipes 8 inside the air supply pipes 7. The hydraulic cylinder 3 is activated to move the placement box 6 upward, thereby drying the self-tapping screws inside the placement box 6, preventing chemical agents from being carried outside the device with the self-tapping screws and thus polluting the environment.

[0030] See Figure 5 Four connecting blocks 15 are respectively engaged inside the four grooves 14, and the fixing plate 13 is located at the bottom of the box 1. A sealing ring is fixedly connected to the bottom of the fixing plate 13, and the sealing ring is located inside the box 1. When the servo motor 9 is started, the fixing plate 13 is driven to rotate, thereby causing the placement box 6 to rotate. This allows the self-tapping screws inside the placement box 6 to rotate, so that the chemical solution can fully contact the self-tapping screws and improve the surface treatment effect.

[0031] In use: Place the device in a horizontal position. The operator pours the chemical solution into the bottom of the box 1. Activate the hydraulic cylinder 3 to move the placement box 6 downwards, causing the four connecting blocks 15 to engage with the four grooves 14. Activate the servo motor 9 to drive the fixed plate 13 to rotate, thereby rotating the placement box 6. This allows the self-tapping screws inside the placement box 6 to rotate, ensuring full contact between the chemical solution and the self-tapping screws, improving the surface treatment effect. Two air pumps 4 are installed on both sides of the box 1. Air is supplied to the air inlet pipe 12 through the air pumps 4, and the center is dried through several air outlet pipes 8 inside the air supply pipe 7. Activate the hydraulic cylinder 3 to move the placement box 6 upwards, thereby drying the self-tapping screws inside the placement box 6 and preventing the chemical agents from being carried outside the device with the self-tapping screws, thus avoiding environmental pollution.
