Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of oil removal devices, in particular to a stamping part oil removal device. Background Art
[0002] Stamping refers to a processing method in which a press and a die are used to apply external force to plates, strips, pipes and profiles to cause them to undergo plastic deformation or separation, thereby obtaining a workpiece (stamping part) of the desired shape and size.
[0003] During the stamping process, it is often necessary to spray stamping oil onto the surface of the stamped part or mold. Most stamping oils are mineral oils, making them particularly suitable for high-intensity operations such as punching, stamping, threading, and grooving. They are also highly suitable for plastic forming processes. They offer excellent lubricity and extreme pressure properties, while also providing excellent mold protection.
[0004] Since the surface of the stamped parts contains a large amount of stamping oil, most of the oil needs to be removed when storing or undergoing subsequent processing. Otherwise, a large amount of oil will seep out during storage, which is not conducive to the subsequent processing of the workpiece. Therefore, it is necessary to design a device that can efficiently remove oil from stamped parts. Utility Model Content
[0005] The purpose of the utility model is to provide a stamping part degreasing device, which can efficiently remove oil from the surface of the stamping part.

[0025] Example
[0026] The following is further described in conjunction with specific embodiments. Figure 1 -Attached Figure 3 As shown, the stamping part degreasing device of this embodiment includes a pair of discharge pipes 1, a degreasing pipe 2 provided at the end of the discharge pipe 1, a discharge pipe 3 provided at the end of the degreasing pipe 2 away from the discharge pipe 1, a first valve 21 provided at the end of the degreasing pipe 2 close to the discharge pipe 3, and a negative pressure device 4 connected to the lower side of the degreasing pipe 2; the ends of the pair of discharge pipes 1 away from the degreasing pipe 2 are arranged close to each other. Specifically, when the parts punched by the stamping machine are discharged into the discharge pipe 1 and enter the degreasing pipe 2 through the discharge pipe 1, the first valve 21 is closed in the degreasing pipe 2, so that the parts gather and temporarily stay in the degreasing pipe 2, and then the negative pressure device 4 is started to absorb the excess oil on the surface of the parts through the negative pressure device 4, thereby reducing the difficulty of subsequent grease treatment on the surface of the workpiece, and also reducing the oil content in the pipeline and the frequency of cleaning and maintenance of the equipment. In addition, by blocking the workpiece by the first valve 21, the moving speed of the workpiece can be reduced, the impact of the workpiece falling can be reduced, and the deformation of the workpiece can be reduced. If the workpiece moves at a slow speed, the first valve 21 may be opened to remove oil from the workpiece during its movement.
[0027] The negative pressure device 4 in this embodiment includes a negative pressure tank 41 disposed below the de-oiling pipe 2, a negative pressure pipe 42 connected to the negative pressure tank 41, a negative pressure machine connected to the negative pressure pipe 42, an oil drain hole 23 provided on the lower side of the de-oiling pipe 2, and an oil drain pipe 43 connecting the oil drain hole 23 and the negative pressure tank 41. Specifically, the negative pressure machine extracts air from the negative pressure tank 41, thereby generating negative pressure in the de-oiling pipe 2 through the oil drain pipe 43, thereby extracting the oil that can flow on the workpiece surface. The extracted oil can be temporarily stored in the negative pressure tank 41. Once a certain amount accumulates, it can be removed and reused.
[0028] In this embodiment, there are multiple oil drain holes 23, each of which is connected to an oil drain pipe 43, and each of which is connected to the negative pressure box 41. Specifically, the multiple oil drain holes 23 can improve the oil drain efficiency.
[0029] In this embodiment, an air inlet pipe 24 is provided on the upper side of the degreasing pipe 2. This inlet pipe 24 is connected to an air compressor, and a filter is installed within the inlet pipe 24. Specifically, the air compressor delivers high-pressure air through the inlet pipe 24 into the degreasing pipe 2 to flush the parts. The air in the degreasing pipe 2 then flows directly into the oil drain pipe 43, forming an air duct that effectively flushes and drains the oil from the parts' surfaces.
[0030] In this embodiment, a pressure tube 44 is connected to the side wall of the negative pressure box 41. The end of the pressure tube 44, away from the negative pressure box 41, is connected to the air compressor. The pressure tube 44 communicates with the upper side of the negative pressure box 41. A valve is provided on the negative pressure tube 42. Specifically, for parts with a large oil content, the negative pressure box 41 can be temporarily stopped during the oil absorption process. The air compressor and pressure tube 44 can then be used to pressurize the negative pressure box 41 (with the valve on the negative pressure tube 42 closed). This allows gas to pass through the oil drain pipe 43 and then be injected into the degreasing pipe 2. This multiple instantaneous impacts on the parts in the degreasing pipe 2 can disrupt the parts and more evenly flush the oil from the part surfaces.
[0031] In this embodiment, the first valve 21 comprises a first baffle 211 disposed within the de-oiling tube 2, a first rotating shaft 213 connected to the side of the first baffle 211, and a first motor 212 connected to the first rotating shaft 213. The first motor 212 is located on the upper outer wall of the de-oiling tube 2. Specifically, the motor drives the first rotating shaft 213 and the first baffle 211 to rotate, thereby opening and closing the first valve 21. Furthermore, by frequently and slightly moving the first baffle 211, the first baffle 211 can also agitate the parts.
[0032] In this embodiment, a second valve 22 is installed at one end of the de-oiling pipe 2 near the discharge pipe 1. The second valve 22 comprises a second baffle 221 disposed within the de-oiling pipe 2, a second rotating shaft connected to the side of the second baffle 221, and a second motor 222 connected to the second rotating shaft. The second motor 222 is located on the upper outer wall of the de-oiling pipe 2. An oil discharge hole 23 is located between the first valve 21 and the second valve 22. Specifically, the first and second valves 21, 22 have substantially identical structures. By simultaneously closing the first and second valves 21, 22, parts can be temporarily trapped between the first and second valves 21, 22. After de-oiling is complete, the first valve 21 is opened to discharge all parts. The first valve 21 is then closed, and the second valve 22 is opened. When a certain amount of parts are present between the first and second valves 21, the second valve 22 is closed, and de-oiling begins. This allows de-oiling to resume after a certain amount of parts have accumulated for low-flow parts, reducing the burden on the negative pressure device 4 and saving energy.
[0033] The oil removal pipe 2 in this embodiment is tilted, with one end of the oil removal pipe 2 close to the discharge pipe 1 being higher than the other end thereof. Specifically, this is more conducive to the automatic movement of the parts under the action of gravity.
[0034] In summary, the stamping parts degreasing device of this embodiment is used to discharge the parts punched by the stamping machine into the discharge pipe 1, and then enter the degreasing pipe 2 through the discharge pipe 1. In the degreasing pipe 2, the first valve 21 is closed, so that the parts gather and temporarily stay in the degreasing pipe 2, and then the negative pressure device 4 is started. The negative pressure device 4 absorbs the excess oil on the surface of the parts, thereby reducing the difficulty of subsequent grease treatment on the surface of the workpiece, and can also reduce the oil content in the pipeline and reduce the frequency of cleaning and maintenance of the equipment. In addition, by blocking the workpiece by the first valve 21, the movement rate of the workpiece can be reduced, the impact of the workpiece falling can be reduced, and the deformation of the workpiece can be reduced. In the case where the workpiece moves slowly, the first valve 21 can also be opened to degreasing the workpiece during the movement of the workpiece.
[0035] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
