Description

Technical Field

[0001] This utility model relates to a water control device for the production of bent pipe shafts, specifically a water control device for removing internal quenching fluid after quenching in the production of automotive bent pipe shafts (truck drive shafts). Background Technology

[0002] After the tube shaft undergoes quenching, the quenching fluid inside needs to be removed. In existing technology, a cylinder is generally used to lift one end of the workpiece, tilting it at a certain angle and holding it for a certain period of time to allow the water (quenching fluid) inside the workpiece to flow away naturally.

[0003] However, when producing bent pipe shafts, this type of water control device takes a long time to control the water, and the quenching liquid inside the workpiece often cannot be effectively drained, which cannot effectively meet the production cycle requirements and affects the production quality of subsequent processes. Utility Model Content

[0004] This utility model proposes a water control device for the production of bent pipe shafts, which aims to overcome the above-mentioned shortcomings of the existing technology and improve the water control effect and efficiency of bent pipe shafts.

[0005] The technical solution of this utility model is a water control device for producing bent pipe shafts. Its structure includes a tilting cylinder, a chain conveyor mechanism, an air-blowing positioning mechanism, and an air-and-water-discharge positioning mechanism. The workpiece is supported on a pair of spaced-apart chain conveyors. A tilting cylinder is located below the workpiece near one of the chain conveyors, and an air-blowing positioning mechanism and an air-and-water-discharge positioning mechanism are located near both ends of the workpiece, respectively. In use, the bent pipe shaft workpiece is positioned on the chain conveyor mechanism and conveyed to the center position corresponding to the air-blowing positioning mechanism and the air-and-water-discharge positioning mechanism, at which point the conveying stops. The air-blowing positioning mechanism and the air-and-water-discharge positioning mechanism press down on both ends of the workpiece. Compressed air is introduced into the air-blowing positioning mechanism to blow away the water inside the workpiece. The blown-out water vapor is discharged through the air-and-water-discharge positioning mechanism. After blowing is completed and air supply stops, the air-blowing positioning mechanism and the air-and-water-discharge positioning mechanism release the workpiece, and the chain conveyor mechanism starts conveying the workpiece to the next station.

[0006] Preferably, the air-blowing positioning mechanism includes a positioning cylinder and a guide sleeve mounted on a positioning bracket. The output end of the positioning cylinder is connected to one end of a top shaft, which is slidably connected inside the guide sleeve and connected to a horn-shaped pressing head at the other end. The horn opening has a conical guide surface corresponding to the outer edge of the workpiece end, and the center of the conical guide surface has a rubber sealing gasket corresponding to the workpiece end position. The side of the pressing head tube is connected to an air inlet, and the air inlet is connected to compressed air.

[0007] Preferably, the air and water positioning mechanism includes a positioning cylinder and a guide sleeve mounted on a positioning bracket. The output end of the positioning cylinder is connected to one end of a top shaft, the top shaft is slidably connected inside the guide sleeve and the other end is connected to a horn-shaped clamping head. A rubber sealing gasket is provided on the inner side of the horn opening of the clamping head, and an air and water outlet is connected to the side of the clamping head tube body. A water collection tank is provided below the air and water outlet.

[0008] The advantages of this utility model are: reasonable structural design, which can use compressed air to quickly dry the water inside bent tube shaft workpieces, with good water control effect and high efficiency, and is compatible with the existing tilting water control method. It is also suitable for straight tube shaft workpieces that only need to be tilted to control water, without causing additional energy consumption. Attached Figure Description

Detailed Implementation

[0012] The present invention will be further described in detail below with reference to embodiments and specific implementation methods.

[0013] like Figure 1 , 2 As shown, a water control device for producing bent pipe shafts includes a tilting cylinder 1, a chain conveyor mechanism 2, an air blowing positioning mechanism, and an air and water outlet positioning mechanism. The workpiece 11 is supported on a pair of chain conveyor mechanisms 2 arranged at intervals. The tilting cylinder 1 is located below the workpiece 11 near one side of the chain conveyor mechanism 2. The air blowing positioning mechanism and the air and water outlet positioning mechanism are respectively located near both ends of the workpiece 11.

[0014] In use, the workpiece 11 of the bent pipe shaft is positioned on the chain conveyor 2, and is driven by the chain at the top to be conveyed to the center position corresponding to the air blowing positioning mechanism and the air and water outlet positioning mechanism. The chain stops conveying, and the air blowing positioning mechanism and the air and water outlet positioning mechanism press down on both ends of the workpiece 11. The air blowing positioning mechanism introduces compressed air to blow away the water inside the workpiece 11. The blown water vapor is discharged through the air and water outlet positioning mechanism. After the blowing is completed and the air supply stops, the air blowing positioning mechanism and the air and water outlet positioning mechanism release the workpiece 11, and the chain conveyor 2 starts to convey the workpiece 11 to the next station.

[0015] The air-blowing positioning mechanism includes a positioning cylinder 5 and a guide sleeve 7 mounted on a positioning bracket 4. The output end of the positioning cylinder 5 is connected to one end of a top shaft 6. The top shaft 6 is slidably connected inside the guide sleeve 7 and the other end is connected to a horn-shaped pressing head 9. The horn mouth is provided with a conical guide surface corresponding to the outer edge of the end of the workpiece 11. The center of the conical guide surface is provided with a rubber sealing gasket 8 corresponding to the end of the workpiece 11. The side of the pressing head 9 tube body is connected to an air inlet 12, and the air inlet 12 is connected to compressed air.

[0016] The air and water positioning mechanism includes a positioning cylinder 5 and a guide sleeve 7 mounted on a positioning bracket 4. The output end of the positioning cylinder 5 is connected to one end of a top shaft 6. The top shaft 6 is slidably connected inside the guide sleeve 7 and the other end is connected to a flared pressing head 9. A rubber sealing gasket 8 is provided on the inner side of the flared opening of the pressing head 9. An air and water outlet 10 is connected to the side of the tube body of the pressing head 9. A water collection tank 3 is provided below the air and water outlet 10.

[0017] During installation, the front end of the top shaft 6 is fixed with bolts to the pressure head 9, and the top shaft 4 is welded with an air outlet / water outlet interface 10 or an air inlet 12.

[0018] In practical use, the positioning cylinders 5 of the air blowing positioning mechanism and the air / water outlet positioning mechanism push the top shaft 6 to drive the clamping head 9 to press down on both ends of the workpiece 11. The conical guide surface in the middle of the clamping head 9 ensures that the workpiece 11 is accurately pressed between the two clamping heads 9, and the rubber sealing gasket 8 on the pressing contact surface ensures sealing. After the workpiece is pressed down, compressed air is introduced through the air inlet 12 to blow away the water inside the workpiece 11. The blown water vapor is sprayed into the lower water collection tank 3 through the air / water outlet 10. After the blowing is completed and the air supply stops, the positioning cylinders 5 on both sides retract, causing the clamping head 9 to release the workpiece 11.

[0019] All of the components described above are existing technologies, and those skilled in the art can use any model and existing design that can achieve their corresponding functions.

[0020] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
