Technical Field

[0001] This application relates to the technical field of spring production, and particularly relates to an anti-rust oil coating production line for spring production. Background Art

[0002] A spring is a mechanical part that works using elasticity. A part made of an elastic material deforms under an external force and returns to its original shape after the external force is removed. Also known as "spring". Generally made of spring steel.

[0003] After the spring is manufactured, in order to improve its service life, an anti-rust oil needs to be applied to its surface. In the prior art, the oil is generally applied by spraying with a nozzle. This method results in uneven coating on the spring surface and affects the service life. Summary of the Invention

The oil immersion and centrifugal drying device includes a bottom plate, a sealing cover, an oil storage tank, a workpiece drum, and a lifting driving mechanism. The sealing cover is fixed on the bottom plate, and a sliding door is installed on the front side of the sealing cover. Both the oil storage tank and the lifting driving mechanism are arranged inside the sealing cover. The lifting driving mechanism is arranged beside the oil storage tank and is used to drive the workpiece drum to lift. The workpiece drum is rotatably installed on the lifting driving mechanism.

The bottom end of the material guiding groove is butt-hinged with a pneumatic rod, and the bottom end of the cylinder is hinged to the frame.

[0008] The lifting drive mechanism includes a bracket, a winch, a fixed pulley, a carrier and a reduction motor. The bracket is vertically fixed on the base plate. The fixed pulley is installed at the top of the bracket. The carrier is slidably connected to the side of the bracket. The winch is fixed on the base and is used to drive the carrier to lift and lower. The workpiece drum is rotatably connected inside the carrier. The reduction motor is fixed on the carrier and is used to drive the workpiece drum to rotate. A driven sprocket is fixed at one end of the workpiece drum, and a driving sprocket is fixed at the end of the output shaft of the reduction motor. A chain is connected between the driving sprocket and the driven sprocket.

[0009] The workpiece drum is formed by bending and welding a perforated plate.

[0022] The following further elaborates on the present application in conjunction with the attached Figures 1-3 drawings.

[0023] An embodiment of the present application discloses an anti-rust oil coating production line for spring production. Referring to Figures 1-3 , it includes an oil-immersed drying device 1, a conveyor 3 arranged beside the oil-immersed drying device 1, and a feeding mechanism 2 arranged between the oil-immersed drying device 1 and the conveyor 3. A plurality of air ducts 4 are evenly arranged on the top of the conveyor 3, and a number of air outlets are installed at the bottom ends of the air ducts 4. The oil-immersed drying device 1 includes a bottom plate 11, a sealing cover 12, an oil storage tank 13, a workpiece drum 14 and a lifting drive mechanism. The sealing cover 12 is fixed on the bottom plate 11, and a sliding door 121 is installed on the front side of the sealing cover 12. Both the oil storage tank 13 and the lifting drive mechanism are arranged inside the sealing cover 12. The lifting drive mechanism is arranged beside the oil storage tank 13 and is used to drive the workpiece drum 14 to lift. The workpiece drum 14 is rotatably installed on the lifting drive mechanism. A feeding port is arranged on the surface of the workpiece drum 14, and a feeding cover 141 is detachably arranged at the feeding port;

[0024] Specifically, referring to Figure 2 , the lifting drive mechanism includes a support 15, a winch 16, a fixed pulley 17, a bearing frame 18 and a reducing motor 19. The support 15 is vertically fixed on the bottom plate 11. The fixed pulley 17 is installed at the top end of the support 15. The bearing frame 18 is slidably connected to the side of the support 15. The winch 16 is fixed on the base and is used to drive the bearing frame 18 to lift. The workpiece drum 14 is rotatably connected inside the bearing frame 18. The reducing motor 19 is fixed on the bearing frame 18 and is used to drive the workpiece drum 14 to rotate. A driven sprocket is fixed at one end of the workpiece drum 14, and a driving sprocket is fixed at the end of the output shaft of the reducing motor 19. A chain is connected between the driving sprocket and the driven sprocket;

[0025] The material guiding mechanism 2 includes a frame 21, a linear vibrating feeder 22, a material guiding groove 23 and a pneumatic rod 24. The linear vibrating feeder is fixed on the frame 21. The material guiding groove 23 is rotatably connected to the frame 21. The bottom end of the material guiding groove 23 is butt-hinged with a pneumatic rod 24, and the bottom end of the air cylinder is hinged to the frame 21;

[0026] A receiving groove 25 is arranged beside the discharging end of the linear vibrating feeder 22. The receiving groove 25 is fixed on the frame 21, and one end of the receiving groove 25 communicates with the conveyor 3.

[0027] By arranging the linear vibrating feeder 22, the wound springs can be separated by using the vibration and separation mode, so that the stacked springs are laid flat on the conveyor 3 as much as possible, increasing the contact area with the air flow, so that the surfaces of the springs remain dry, which is convenient for subsequent packing.

[0028] Refer to Figure 3 , the workpiece drum 14 is bent and welded by a perforated plate. A plurality of baffles 142 are uniformly arranged along the length direction inside the workpiece drum 14. By arranging the baffles 142, the springs can be carried to a high place and then dropped, so that the springs can be fully contacted with the rust preventive oil.

[0029] In order to facilitate the return of the flung rust preventive oil to the oil storage tank 13, the oil storage tank 13 is hermetically attached to the inner wall of the sealing cover 12.

[0030] The implementation principle of an anti-rust oil coating production line for spring production in the embodiment of the present application is as follows:

[0031] During use, the staff puts the springs into the workpiece drum 14 and closes the feeding cover 141. The winch 16 lowers the carrier 18 into the oil storage tank 13, and the whole workpiece drum 14 is immersed in the oil storage tank 13. During this process, the reduction motor 19 drives the workpiece drum 14 to rotate slowly, and the springs in the workpiece drum 14 can be in full contact with the rust preventive oil, and the surfaces of the springs are evenly coated with oil, and the oil coating effect is good. After the springs are immersed in the oil for a period of time, the winch 16 drives the workpiece drum 14 to rise. At this time, the reduction motor 19 drives the workpiece drum 14 to rotate at an accelerated speed, and under the centrifugal action, the excess rust preventive oil on the surfaces of the springs is thrown dry;

[0032] After the springs are thrown dry, the material guiding groove 23 is adjusted to the side of the material outlet of the workpiece drum 14. The staff opens the feeding cover 141, and the springs enter the linear vibrating feeder 22 through the material guiding groove 23. The wound springs are separated by using the vibration and separation mode, so that the stacked springs are laid flat and transported to the conveyor 3 as much as possible. After that, the air outlet nozzle blows air on the springs, so that the surfaces of the springs remain dry, which is convenient for subsequent packing.

[0033] The above are all preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
