Description

Technical Field

[0002] The traditional elbow production process usually involves a lot of mechanical operations and energy consumption. Traditional heating methods such as flame heating or resistance heating have low energy utilization and low production efficiency, and induction heating is needed to push the elbow device.

[0003] In the prior art, the induction heating device generally includes an induction coil, a pushing device and a cooling system. The induction coil is arranged in the elbow forming area. The pushing device includes a push rod, a pushing system and a positioning system. The cooling system is provided with a cooling water system or a gas cooling system. The high-frequency current is provided by the induction power supply to quickly heat the elbow material to the required temperature. The pushing system can accurately control the movement trajectory and speed of the push rod to ensure that the elbow material can be formed according to the predetermined bending angle and curve after heating. The cooling system is used to quickly cool the elbow after forming to solidify the shape.

[0004] However, when the above-mentioned device is cooling, the elbow pipe is generally placed on the ground for natural cooling. The cooling speed is slow and the high-temperature softened elbow pipe placed on the ground will have a certain probability of deformation, or the staff is required to take it to a water tank for cooling, which increases the work intensity of the staff and also increases certain safety risks. There is also direct water spray cooling on the pipeline. This cooling generally sprays water at one side of the elbow pipe. If it is a common round pipe, the water can slide to the back, and if it is a square pipe, it is difficult to cool the back of the elbow pipe. Summary of the invention

[0028] One end of the positioning plate of the pushing device 2 is fixedly connected to a connecting rod 36, and the bottom of the connecting rod 36 is fixedly connected to a rack 28. The bottom of the machine table 1 is fixedly connected to a mounting plate, and one end of the mounting plate is rotatably connected to a rotating shaft 26 through a bearing. The surface of the rotating shaft 26 is fixedly connected to a gear 27, and the gear 27 is meshed with the rack 28.

The rotation of the rotating shaft 26 can cause the gear 27 to rotate, and the rotation of the gear 27 can cause the rotating disk 23 to rotate.

[0029] The conveying mechanism includes a fixed frame 29 located below the cooling ring 6, and a rotatable conveyor belt 30 is fixedly connected to the inner wall of the fixed frame 29.

The square cooling ring 6 can cool down the surrounding of the square tube at the same time to ensure the cooling effect. At this time, the cooling shaft 11 in the cooling port 9 will rotate with the blade 12 under the water pressure. The rotation of the blade 12 can change the direction of the water to a certain extent, increase the cooling area of ​​the square tube, and achieve a rapid cooling effect. During the cooling operation, the movement of the rack 28 as pushed by the pushing device 2 can cause the gear 27 to rotate, the rotation of the gear 27 can cause the rotating disk 23 to rotate, and the rotation of the rotating disk 23 can cause the vacuum pump 15 to move up and down. At this time, the intermittent door 14 will move up and down in the inner wall of the intermittent opening 13, so that the cooling port 9 can be intermittently opened and closed, which can reduce the amount of water vapor generated when in contact with high temperature. At the same time, the up and down movement of the vacuum pump 15 can flexibly extract water vapor from the upper and lower parts of the square tube, so that the missed discharged water vapor can be extracted, and the heating operation of the square tube can be guaranteed; The square tube after cooling can fall onto the baffle 33, and after sliding onto the conveyor belt 30 through the baffle 33, it can be blocked by the drain port 32, which can slow down the square tube to prevent the square tube from sliding out.
