Description

Technical Field

[0001] This utility model relates to the field of suspension spring coating, and in particular to a coating device for suspension spring production. Background Technology

[0002] In the automotive industry, suspension springs are important load-bearing and shock-absorbing components, and their coating quality directly affects the product's corrosion resistance, mechanical strength, and appearance quality.

[0003] Currently, the paint storage tanks of traditional suspension spring coating equipment often lack an effective stirring structure. When the paint is left to stand, pigment sedimentation and stratification are very likely to occur, resulting in uneven coating thickness and inconsistent color during the spraying process, which seriously affects the product qualification rate. Secondly, the paint splashing during the spraying process generates a large amount of residual material, which is often directly discarded, causing resource waste and increasing the cost of hazardous waste disposal. In order to solve the above problems, we propose a coating device for suspension spring production. Utility Model Content

[0004] The main objective of this invention is to provide a coating device for suspension spring production, which can effectively solve the problems in the background art.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figure 1-5 As shown, a coating device for suspension spring production includes a base plate 1, a paint storage tank 2 fixedly connected to the upper end of the base plate 1, a stirring assembly arranged inside the paint storage tank 2, a turntable 6 rotatably connected to the upper end of the paint storage tank 2, a plurality of spring placement racks 17 fixedly connected to the upper end of the turntable 6, a baffle 9 arranged at the upper end of the base plate 1, the baffle 9 being located outside the paint storage tank 2, two spraying assemblies arranged on the outside of the paint storage tank 2, both spraying assemblies being located on the side away from the baffle 9, and a plurality of support legs 18 fixedly connected to the lower end of the base plate 1 along the circumferential direction.

[0024] In this embodiment, a liquid collection tank 10 is fixedly connected to the lower end of the baffle 9, and a connecting pipe 11 is fixedly connected to the outer side of the liquid collection tank 10. The other end of the connecting pipe 11 is located in the inner cavity of the paint storage tank 2. A scraper 8 is fixedly connected to the outer side of the turntable 6. The scraper 8 slides on the inner side of the baffle 9. A plurality of connecting posts 12 are fixedly connected to the lower end of the connecting pipe 11. The plurality of connecting posts 12 are all fixedly connected to the upper end of the base plate 1. The spraying assembly includes a pressure pump 14. The feed end of the pressure pump 14 is located in the inner cavity of the paint storage tank 2. A conveying pipe 15 is fixedly connected to the output end of the pressure pump 14. A plurality of nozzles 16 are fixedly connected to the outer side of the conveying pipe 15. The plurality of nozzles 16 are all located on the side close to the spring placement frame 17. Two connecting clamps 13 are connected to the outer side of the baffle 9. The two connecting clamps 13 are all fixedly connected to the outer side of the two conveying pipes 15.

[0025] Specifically, the suspension spring to be sprayed is first placed on the outside of the spring placement rack 17. Then, the pressure pump 14 is started to extract the paint from the paint storage tank 2 and spray it evenly onto the spring through the delivery pipe 15 and multiple nozzles 16. During the spraying process, the rotation of the turntable 6 will drive the scraper 8 to rotate, which can easily scrape off the paint splashed on the inside of the baffle 9. At this time, the paint will flow into the collection tank 10 and then flow back to the paint storage tank 2 through the connecting pipe 11, thereby realizing the recycling of paint and ensuring that the entire coating process is carried out efficiently and orderly.

[0026] In this embodiment, the stirring assembly includes a rotating rod 4, the upper end of which is fixedly connected to the turntable 6, and the lower end of which is rotatably connected to the base plate 1. Multiple stirring rods 5 are fixedly connected to the outer side of the rotating rod 4, and the multiple stirring rods 5 are all located in the inner cavity of the paint storage tank 2. A drive motor 3 is provided at the lower end of the base plate 1, and the output end of the drive motor 3 is fixedly connected to the rotating rod 4.

[0027] Specifically, by starting the drive motor 3, the output end of the drive motor 3 will drive the rotating rod 4 to rotate, which in turn causes the stirring rod 5 fixed on the rotating rod 4 to continuously stir the paint in the paint storage tank 2, preventing sedimentation and stratification. At the same time as the rotating rod 4 rotates, it will also drive the upper turntable 6 to rotate. More specifically, a feed pipe is provided on the outside of the paint storage tank 2. The feed pipe is not shown in the attached drawings, but the setting of the feed pipe is a conventional technology in this technical field, so it will not be described in detail in this application.

[0028] In this embodiment, the upper end of the turntable 6 is provided with a plurality of leakage holes 7, and the plurality of leakage holes 7 are all located above the inner cavity of the paint storage tank 2.

[0029] Specifically, during the spraying process, excess paint falls into the inner cavity of the paint storage tank 2 through the drain hole 7 on the turntable 6, thereby realizing the recycling of paint.

[0030] In this embodiment, a mounting block 19 is fixedly connected to the outside of the drive motor 3, and the mounting block 19 is fixedly installed at the lower end of the base plate 1.

[0031] Specifically, the design of mounting block 19 can improve the stability of drive motor 3 during operation.

[0032] It should be noted that this utility model is a coating device for suspension spring production. The user places the suspension spring to be coated on the outside of the spring placement rack 17, and then starts the drive motor 3. The output end of the drive motor 3 will drive the rotating rod 4 to rotate, which in turn causes the stirring rod 5 fixed on the rotating rod 4 to continuously stir the coating in the coating storage tank 2, preventing sedimentation and stratification. At the same time as the rotating rod 4 rotates, it will also drive the upper turntable 6 to rotate. The rotation of the turntable 6 will drive multiple spring placement racks 17 to rotate accordingly, thereby realizing that multiple suspension springs are in dynamic rotation. In this state, the pressure pump 14 is activated to extract the paint from the paint storage tank 2 and spray it evenly onto the spring through the delivery pipe 15 and multiple nozzles 16. During the spraying process, excess paint falls into the inner cavity of the paint storage tank 2 through the drain hole 7 on the turntable 6. As the turntable 6 rotates, it also drives the scraper 8 to rotate, which can easily scrape off the paint splashed on the inside of the baffle 9. At this time, the paint will flow into the collection tank 10 and then flow back to the paint storage tank 2 through the connecting pipe 11, thereby realizing the recycling of paint and ensuring that the entire coating process is efficient and orderly, which is quite practical.
