Description

Technical Field

[0001] The utility model relates to the technical field of semicircular tube processing, in particular to a semicircular tube curling device. Background Art

[0002] Semi-circular steel pipes are a specialty type of steel pipe that has emerged in recent years in response to market demand. They are widely used in anti-wear tiles, anti-wear covers, and anti-wear protective tiles. As the name suggests, semi-circular pipes resemble pipes cut in half using a wire cutter, resulting in two semi-circular structures. They are manufactured by rolling steel strips through rolling equipment. They are primarily used to wrap around the outer surface of steel pipes to protect them from wear. Made primarily of heat-resistant stainless steel, semi-circular pipes require a bending device to ensure bending accuracy and quality.

[0003] At present, most bending devices used for semi-circular tube processing are usually composed of a box body and a cam and a concave wheel corresponding to the upper and lower cams installed on one side. The transmission of the gear set in the box is driven by a reducer to realize the rotation of the cam and the concave wheel, thereby realizing the rolling processing of the steel strip. The use of gears requires workers to add lubricating oil to them regularly in order to reduce friction and wear between gears, improve transmission efficiency, reduce noise and vibration, and play a role in cooling and heat dissipation, prevent gears from overheating and damage, etc., so as to protect the gears and extend their service life. However, most bending devices used for semi-circular tube processing usually lack the function of automatically and regularly adding lubricating oil to the gears in the equipment, which is inconvenient to use, increases the workload of the staff, and has relatively poor practicality.

The setting of the oil adding component can be dynamically linked with the linkage component, thereby continuously driving the lubricating oil entering the pump barrel 22 to be delivered to the temporary storage box 25 for gradual accumulation. When the weight of the lubricating oil in the temporary storage box 25 is greater than the elastic force of the spring 2 30, the sealing block 32 is separated from the guide block 26, so that the lubricating oil flows through the guide block 26 and then into the branch pipe, and is distributed through the refueling pipe, so that the lubricating oil is added to the gear, realizing the addition of gear lubricating oil. The lubricating oil can be added intermittently, which reduces the workload of workers and extends the service life of the gears, making it more practical.

[0024] In this example, the gear assembly includes Gear 1, which is rotatably mounted within the lower portion of housing 3. One end of the connecting shaft of the two cams 1 5 is sleeved within housing 3 with Gear 2, which meshes with Gear 1. The connecting shaft of the cam 4, located near the pinion 10, is sleeved within housing 3 with Gear 3, which meshes with Gear 2 below.

In this example, the connecting sleeve 13 is rotatably connected to the sleeve 12 via a bearing. The width of the stopper 19 is greater than that of the protrusion 16. Sealing rings are sleeved on the outer walls of the piston 23 and the outer walls of the sealing block 32 to ensure that the protrusion 16 remains in contact with the stopper 19 after movement. The provision of the sealing ring improves its sealing performance. In this example, the inner wall of the connector 31 and the outer wall of the temporary storage box 25 are respectively provided with internal threads and external threads that adapt to each other. The temporary storage box 25 is threadedly connected to the connector 31. A handle is provided at the bottom of the guide block 26, and the guide block 26 is threadedly connected to the temporary storage box 25, which facilitates the disassembly of the temporary storage box 25 and the guide block 26 to facilitate maintenance and replacement of components in the temporary storage box 25.

[0025] The working principle of the present utility model is as follows: when in use, the steel strip is processed after passing through the feeding assembly 6 and then between the cam 1 5 and the feeding assembly 6, and then bent by the cam 2 8; and the timer switch 15 is set as needed to control the time of starting the telescopic rod 14, so that the telescopic rod 14 can be controlled to start at intervals. When the telescopic rod 14 starts, it pushes the connecting sleeve 13 to drive the sleeve 12 to slide on the rotating shaft 11, and cooperates with the guide block 18 to guide it, and the movement of the sleeve 12 drives the protrusion 16 and the driven gear 1 7 moves, so that the driven gear 17 meshes with the pinion 10, so that the pinion 10 drives the driven gear 17 to drive the sleeve 12 to rotate, and then drives the rotating shaft 11 to rotate, and the sleeve 12 will drive the protrusion 16 to rotate, so that the protrusion 16 will continuously push the stopper 19, so that the stopper 19 drives the push rod 21, and then the push rod 21 drives the piston 23 to move, so that the piston 23 squeezes the spring 1 24. When the protrusion 16 moves away from one end of the sleeve 12 and gradually moves away from the stopper 19, the piston 23 will drive the push rod 21 to reset the stopper 19 under the elastic force of the spring 1 24. The piston 23 is moved back and forth in this way, and the movement of the piston 23 will continuously push the oil into the pump barrel 22, thereby delivering it to the temporary storage box 25 and accumulating it above the guide block 26. When the weight of the lubricating oil accumulated above the guide block 26 is greater than the elastic force of the spring 2 30, the sealing block 32 will drive the support rod 28 to move downward, and the support rod 28 will drive the fixed block 29 to squeeze the spring 2 30, so that the sealing block 32 and the guide block 26 are separated, so that the oil above the guide block 26 passes through and then enters the branch pipe for distribution to Several refueling pipes are inserted to add lubricating oil to the gear below. The rotation of the gears will transfer the lubricating oil between the adjacent gears, thereby adding lubricating oil to the gears. After the addition is completed, the telescopic rod 14 will be controlled to start under the action of the timing switch 15, so that the driven gear 17 is separated from the sub-gear 10 and restored to the initial position, and the addition of lubricating oil is stopped. This reciprocating operation can achieve the operation of adding lubricating oil to the gears at regular intervals, making it easy to use, reducing the workload of the staff, and being more practical.
