Description

Technical Field

[0001] This utility model relates to the field of oil seal processing, and in particular to a stamping device for lubrication grooves on the surface of an oil seal. Background Technology

[0002] Oil seals, also known as shaft seals or rotary shaft lip seals, are sealing elements used to prevent lubricating oil leakage and the intrusion of external impurities into mechanical equipment. They are widely used in various rotating machinery, such as engines, transmissions, and hydraulic pumps, and are important components for ensuring normal equipment operation and extending service life.

[0003] However, when stamping the lubrication grooves on the oil seal surface, the oil seal may be difficult to eject smoothly due to its tight fit with the mold. Traditional mechanical ejection methods, such as using ejector pins, require gradual application of force, which may cause scratches or other damage to the oil seal surface, affecting its sealing performance and appearance. Excessive localized tension may also be applied at the contact point between the oil seal and the mold, causing deformation of the oil seal.

[0004] Therefore, this utility model proposes a stamping device for lubrication grooves on the surface of an oil seal. Utility Model Content

[0005] This invention provides a stamping device for lubrication grooves on the surface of an oil seal, which can solve the problem that the use of tools such as push rods for material removal in the prior art may cause scratches, deformation and other damage to the surface of the oil seal.

[0006] A device for stamping lubrication grooves on the surface of an oil seal, comprising:

[0007] The system comprises a base, a stamped part, and a stripper. The stamped part, mounted on the base, is used to stamp the surface of the oil seal. The stripper is symmetrically arranged on both sides of the stamped part and is used to remove the oil seal adhering to the stamped part. The stripper includes a fixing plate fixedly mounted on the base; a second cylinder is mounted on the fixing plate; a connecting frame is connected to the telescopic end of the second cylinder; collars are connected to both ends of the connecting frame; and a stripper plate passes through the collars.

[0008] Preferably, the stamped part includes a fixed frame fixedly mounted on a base; a cylinder is mounted on the fixed frame; a pressure plate is connected to the telescopic end of the cylinder; a mold is mounted on the base; and the pressure plate is configured to cooperate with the mold.

[0009] Preferably, the stripper plate is a semi-circular plate that is fitted to the side wall of the pressure plate.

[0010] Preferably, an insert plate is fixedly connected to the lower end of the stripping plate.

[0011] Preferably, a motor is provided on one side of the connecting frame; the drive end of the motor is connected to a sector gear; the side wall of the stripper plate is provided with teeth, and the teeth are meshed with the sector gear.

[0012] Preferably, the lower end of the stripper plate is evenly hinged with multiple ball bearings.

[0013] Preferably, one end of the stripper plate is provided with a protrusion, and the other end of the stripper plate is provided with a slot; the protrusion and the slot are engaged and locked together.

[0014] Preferably, the stripping plate has a cavity; the fixed plate has an air pump; the air pump is connected to a connecting pipe; the other end of the connecting pipe is connected to the cavity in the stripping plate; and the side wall of the stripping plate has multiple air holes evenly distributed.

[0015] Preferably, multiple air holes are opened at opposite ends of the two stripper plates.

[0016] Preferably, the connecting pipe is a corrugated pipe.

[0017] Compared with the prior art, the present invention has the following beneficial technical effects:

[0018] (1) The oil seal surface lubrication groove stamping device is fixedly mounted on a base plate; the fixed plate is equipped with a second cylinder; the telescopic end of the second cylinder is connected to a connecting frame; both ends of the connecting frame are connected to collars; a stripper plate passes through the collar; a motor is mounted on one side of the connecting frame; the drive end of the motor is connected to a sector gear; the side wall of the stripper plate is toothed and meshes with the sector gear through the teeth. By starting the motor, the sector gear is driven to rotate reciprocally, thereby driving the two stripper plates to rotate reciprocally, causing multiple balls to roll and rub against the upper surface of the oil seal. Through uniform force distribution, the friction and adsorption between the oil seal and the pressure plate can be overcome more effectively, allowing the oil seal to detach from the pressure plate more quickly. At the same time, it can avoid the oil seal shape from changing due to excessive local force, ensuring the dimensional accuracy and shape integrity of the oil seal.

[0019] (2) The oil seal surface lubrication groove stamping device has a cavity inside the stripper plate; an air pump is installed on the fixed plate; a connecting pipe is connected to the air pump; the other end of the connecting pipe is connected to the cavity inside the stripper plate; multiple air holes are evenly opened on the side wall of the stripper plate. By starting the air pump, airflow is blown out from the air holes along the connecting pipe, thereby blowing air into the gap between the oil seal and the pressure plate, so that the air quickly fills the gap between the oil seal and the pressure plate, forming a separation force. This shortens the stripping time of each oil seal and reduces the risk of damage to the oil seal during the stripping process. Attached Figure Description

[0025] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0026] like Figure 1-3 As shown in the figure, an embodiment of the present invention provides a stamping device for a lubrication groove on an oil seal surface, comprising a base 1, a stamping part 2, and a stripping part 3. The stamping part 2 is disposed on the base 1 and is used to stamp the surface of the oil seal. The stripping part 3 is symmetrically disposed on both sides of the stamping part 2 and is used to remove the oil seal adhering to the stamping part 2; the stripping part 3 includes a fixing plate 31 fixedly disposed on the base 1; a cylinder 32 is disposed on the fixing plate 31; a connecting frame 33 is connected to the telescopic end of the cylinder 32; collars 34 are respectively connected to both ends of the connecting frame 33; a stripping plate 35 passes through the collars 34.

[0027] Further explanation: The stamped part 2 includes a fixed frame 21 fixedly mounted on the base 1; a cylinder 22 is mounted on the fixed frame 21; a pressure plate 23 is connected to the telescopic end of the cylinder 22; a mold 24 is mounted on the base 1; the pressure plate 23 is configured to cooperate with the mold 24. A resistance wire is installed inside the pressure plate 23, which can heat the material during stamping to help shape it. By activating the cylinder 22, the pressure plate 23 is pressed down, thus stamping the oil seal.

[0028] To further explain, the stripper plate 35 is a semi-annular plate that fits snugly against the side wall of the pressure plate 23. An insert plate 36 is fixedly connected to the lower end of the stripper plate 35. During the process of the cylinder 22 driving the pressure plate 23 to rise, the insert plate 36 can be inserted into the gap between the pressure plate 23 and the oil seal, ensuring successful stripping and preventing the stripper plate 35 from falling off the surface of the oil seal.

[0029] Further explanation: A motor 37 is mounted on one side of the connecting frame 33; a sector gear 38 is connected to the drive end of the motor 37; the side wall of the stripper plate 35 has teeth, which mesh with the sector gear 38. This allows the stripper plate 35 to reciprocate and rub against the upper surface of the oil seal. Through uniform force distribution, it can more effectively overcome the friction and adhesion between the oil seal and the pressure plate 23, allowing the oil seal to detach from the pressure plate 23 more quickly. Simultaneously, it avoids changes in the shape of the oil seal due to excessive local force, ensuring the dimensional accuracy and shape integrity of the oil seal. Multiple ball bearings 39 are evenly hinged at the lower end of the stripper plate 35. This reduces the friction between the stripper plate 35 and the oil seal, preventing wear on the oil seal surface caused by the stripper plate 35. A protrusion 313 is provided at the end of one side of the stripper plate 35, and a slot 314 is provided at the end of the other side of the stripper plate 35; the protrusion 313 and the slot 314 engage and lock together. Two stripper plates 35 can be connected together so that the two stripper plates 35 rotate together.

[0030] Further explanation: A cavity is formed within the stripping plate 35; an air pump 310 is mounted on the fixed plate 31; a connecting pipe 311 is connected to the air pump 310; the other end of the connecting pipe 311 communicates with the cavity within the stripping plate 35; multiple air holes 312 are evenly distributed on the sidewall of the stripping plate 35. These air holes 312 are located at opposite ends of the two stripping plates 35. Air can be blown into the gap between the oil seal and the pressure plate 23, allowing air to quickly fill the gap, creating a separation force, shortening the stripping time of each oil seal, and reducing the risk of damage to the oil seal during the stripping process. The connecting pipe 311 is a corrugated pipe, allowing it to extend and retract as the stripping plate 35 moves.

[0031] The working principle of this utility model is as follows: During operation, the material is first placed in the mold 24, and then the cylinder 22 is activated to drive the pressure plate 23 to descend, pressing the material. At the same time, the resistance wire inside the pressure plate 23 is activated to help shape the material. After the pressing is completed, the cylinder 22 drives the pressure plate 23 to rise, and the oil seal adheres to the surface of the pressure plate 23. At this time, the cylinder 32 is activated to drive the connecting frame 33 to move towards the pressure plate 23, and the protrusion 313 engages with the slot 314, so that the two stripper plates 35 together cover the side wall of the pressure plate 23, and the insert plate 36 is inserted into the gap between the oil seal and the pressure plate 23. Then, the air pump 310 is activated, and the airflow is blown out from the air hole 312 through the connecting pipe 311, thereby blowing air into the gap between the oil seal and the pressure plate 23, so that the air quickly fills the gap between the oil seal and the pressure plate 23, forming a separation force. Simultaneously, the motor 37 is started, driving the sector gear 38 to reciprocate, which in turn drives the two stripper plates 35 to reciprocate. This causes multiple balls 39 to roll and rub against the upper surface of the oil seal. Through uniform force distribution, the friction and adhesion between the oil seal and the pressure plate 23 can be overcome more effectively, allowing the oil seal to detach from the pressure plate 23 more quickly. At the same time, it can prevent the shape of the oil seal from changing due to excessive local force, ensuring the dimensional accuracy and shape integrity of the oil seal.

[0032] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
