Description

Technical Field

[0001] This application relates to the technical field of sheet metal spraying components, and in particular to a sheet metal spraying device. Background Technology

[0002] In the production process of sheet metal parts, in order to prevent rust and improve appearance, it is usually necessary to spray an oil film on the surface. The traditional manual oil spraying method is not only inefficient, but also uneven, which can easily lead to waste of resources and environmental pollution.

[0003] The existing announcement number CN208374014U, entitled "A Sheet Metal Stamping Oil Spraying Device," includes a bracket, a lead lever, a first bearing, a guide rod, a lead screw nut, a motor, a slider, a first connecting rod, a second connecting rod, a roller, a second bearing, a sleeve, a first spring, a second spring, an oil inlet pipe, and an oil spraying pipe. The oil spraying device, mounted on a support frame, can automatically spray lubricating oil before the protective film is applied, replacing manual lubricating oil spraying. This further improves production efficiency, better protects products from damage, and significantly reduces potential hazards during production. Furthermore, the roller ensures uniform coating of lubricating oil on the stamped parts, greatly extending the life of the stamping die.

[0004] Regarding the aforementioned technologies, the inventors discovered that in the above-mentioned sheet metal stamping and spraying, the sprayed oil falls downwards under the influence of gravity. The falling oil lacks a recovery component, and the dripping oil causes environmental pollution and wastes the oil. Utility Model Content

[0005] In order to overcome the problems of existing sheet metal stamping oil spraying, where the sprayed oil falls downwards under the action of gravity, and the lack of a recovery component for the falling oil causes environmental pollution and waste, this application provides a sheet metal oil spraying device.

[0006] The sheet metal spraying device provided in this application adopts the following technical solution:

[0007] A sheet metal spraying device includes a spray box and a recovery unit. Four sprockets are symmetrically and horizontally arranged inside the spray box, and the top shafts of the four sprockets are rotatably connected to the top surface of the spray box. Chains are tensioned and connected to the four sprockets, and two spraying components are symmetrically and vertically arranged on one side of the chain. The recovery unit includes an oil drop box with an opening on its top surface, which is fixedly connected to the bottom surface of the spray box. A drawer slot is horizontally opened through the front end of the oil drop box, and a filter frame box is horizontally slidably inserted into the drawer slot. A mesh is horizontally fixed through the bottom surface of the filter frame box, and a cloth pad is horizontally fixed to the top surface of the mesh. An oil drain pipe is vertically fixed to the bottom surface of the filter frame box, and a valve is fixedly connected to the oil drain pipe.

[0008] By adopting the above technical solution, the sheet metal parts that need to be sprayed with oil are placed inside the spray box. The sheet metal parts are hung on the chain by hooks. The sprocket rotates, driving the chain to rotate, carrying the hung sheet metal parts between two spray nozzles. Oil is sprayed onto the surface of the sheet metal parts on both sides by the two spray nozzles, forming an oil film. After spraying, the sheet metal parts are conveyed by the chain and finally recycled. The sprayed oil falls into the recycling container and then into the oil drop box. The oil is filtered by the mesh and cloth pad in the filter box to remove impurities. The recycled oil is discharged by opening the valve on the drain pipe and collected in a centralized manner. Thus, the sprayed oil is recycled by the recycling container, avoiding environmental pollution and waste caused by dripping oil.

[0009] Optionally, a motor is vertically fixed on the top surface of the fuel injection box, and the output end of the motor is fixed on the shaft of the sprocket.

[0010] By adopting the above technical solution, the motor on the paint spray box starts and drives the sprocket to rotate, which in turn drives the chain to move the attached sheet metal parts to perform paint spraying.

[0011] Optionally, studs are evenly and vertically fixed on the bottom surface of the chain, and hooks are vertically provided below the bottom surface of the chain.

[0012] By adopting the above technical solution, the studs on the bottom surface of the chain are used to assemble and connect the hooks, and the hooks are used to hang sheet metal parts.

[0013] Optionally, a screw tube is vertically fixed on the top surface of the hook, and the screw tube of the hook is threaded onto the stud.

[0014] By adopting the above technical solution, the screw tube on the hook is assembled on the stud, and an appropriate number of hooks are selected according to the size of the sheet metal parts to hang sheet metal parts of different sizes.

[0015] Optionally, the spraying component includes a spray plate, which is horizontally arranged inside the spray box. Multiple spray rods are horizontally and vertically connected and fixed on the bottom surface of the spray plate. A pipe is vertically connected and fixed on the top surface of the spray plate, and the top end of the pipe is arranged through the top surface of the spray box. An interface is connected and fixed at the top end of the pipe.

[0016] By adopting the above technical solution, when spraying oil on the surface of sheet metal parts, the top interface of the pipe is connected to the oil supply pipe, and then the oil is transported to the spray plate through the pipe. The oil is then sprayed onto the surface of the sheet metal parts through the nozzles on multiple spray bars.

[0017] Optionally, a guide rod is vertically fixed on the top surface of the spray plate, and the guide rod slides vertically through the top surface of the spray box. A hydraulic rod is vertically fixed on the top surface of the spray box, and the output end of the hydraulic rod is fixed on the top surface of the spray plate.

[0018] By adopting the above technical solution, the hydraulic rod is extended, pushing the spray plate vertically downward on the guide rod, causing the spray plate to move vertically, thus avoiding spraying oil on sheet metal parts in the vertical direction.

[0019] Optionally, a feeding port is provided on one side of the front face of the paint spray box, and a discharging port is provided on the other side of the front face of the paint spray box.

[0020] By adopting the above technical solution, the feeding port on the spray gun is used to place the sheet metal parts into the spray gun, and the unloading port on the spray gun is used to remove the sheet metal parts after spraying and put them into the spray gun.

[0021] Optionally, a bracket is vertically fixed to the bottom surface of the fuel injection box, and an exhaust pipe is fixedly connected to the top surface of the fuel injection box.

[0022] By adopting the above technical solution, the fuel injection box is supported and lifted by a bracket, and the exhaust pipe installed on the top surface of the fuel injection box is used to discharge the exhaust gas of the fuel injection box.

[0023] In summary, this application includes at least one of the following beneficial technical effects: During use, the sheet metal parts requiring oil spraying are placed inside the oil spray box. The sheet metal parts are hung on a chain via hooks. The sprocket rotates, driving the chain to rotate, carrying the hung sheet metal parts between two oil sprayers. Oil is sprayed onto the surface of the sheet metal parts on both sides by the two oil sprayers, forming an oil film. After spraying, the sheet metal parts are conveyed by the chain and finally recycled. The sprayed oil falls into the recycling container and then into the oil drop box. The oil is filtered by the mesh and cloth pad in the filter box to remove impurities. The recycled oil is discharged by opening the valve on the drain pipe and collected centrally. Thus, the sprayed oil is recycled by the recycling container, avoiding environmental pollution and waste caused by dripping oil. Attached Figure Description

[0031] This application discloses a sheet metal parts spraying device. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 5 A sheet metal spraying device includes a spraying box 1 and a recovery component 2. Four sprockets 11 are symmetrically and horizontally arranged inside the spraying box 1, and the top shafts of the four sprockets 11 are rotatably connected to the top surface of the spraying box 1.

A drawer slot is horizontally opened through the front end of the oil drop box 21, and a filter frame box 23 is horizontally slidably inserted into the drawer slot. A mesh is horizontally fixed through the bottom surface of the filter frame box 23, and a cloth pad 24 is horizontally fixed on the top surface of the mesh. An oil drain pipe 22 is vertically fixed to the bottom surface of the filter frame box 23, and a valve is fixedly connected to the oil drain pipe 22.

[0032] By adopting the above technical solution, the sheet metal parts that need to be sprayed with oil are placed inside the spray box 1. The sheet metal parts are hung on the chain 12 by the hook 13. The sprocket 11 rotates, driving the chain 12 to rotate, carrying the hung sheet metal parts between two spraying parts 15. The two sides of the sheet metal parts are sprayed with oil by the two spraying parts 15, forming an oil film. After the sheet metal parts are sprayed, they are transported by the chain 12 and finally recycled. The sprayed oil falls into the recycling unit 2 and then into the oil drop box 21. The oil is filtered by the mesh and cloth pad 24 in the filter box 23 to remove impurities. The recycled oil is discharged by opening the valve on the drain pipe 22 and collected in a centralized manner. Thus, the sprayed oil is recycled by the recycling unit 2, avoiding environmental pollution and waste caused by dripping oil.

[0033] Reference Figure 3A motor 14 is vertically fixed on the top surface of the paint spray box 1, and the output end of the motor 14 is fixed on the shaft of the sprocket 11. When the motor 14 on the paint spray box 1 starts, it drives the sprocket 11 to rotate, which in turn drives the chain 12 to move the suspended sheet metal parts through which they are sprayed with oil.

[0034] Reference Figure 3 The chain 12 has studs 121 evenly and vertically fixed on its bottom surface, and hooks 13 are vertically installed below the bottom surface of the chain 12.

[0037] The implementation principle of the sheet metal spraying device in this application embodiment is as follows: During use, the sheet metal parts that need to be sprayed are placed inside the spraying box 1. The sheet metal parts are hung on the chain 12 by the hook 13. The sprocket 11 rotates and drives the chain 12 to rotate, carrying the hung sheet metal parts through the two spraying parts 15. The two sides of the sheet metal parts are sprayed with oil on the surface by the two spraying parts 15, forming an oil film. After the spraying is completed, the sheet metal parts are transported by the chain 12 and finally recycled. The sprayed oil falls into the recycling part 2 and then into the oil drop box 21. The oil is filtered by the mesh and cloth pad 24 in the filter box 23 to remove impurities from the oil. The recycled oil is discharged by opening the valve on the drain pipe 22 and collected centrally.
