Description

Technical Field

[0002] At present, the high-frequency welded pipe industry adopts the front and back butt joint of the strip steel coil to achieve continuous production. In the process of butt jointing of the strip steel coil, the efficiency of butt jointing greatly affects the efficiency of the entire production line; at the same time, the quality of the joint and the protection of the surface quality of the steel strip during butt jointing are also very important. In the butt jointing process of the strip steel coil, the role of the leveling machine is to level the head and tail of the strip steel coil to facilitate shearing and butt welding. The existing leveling machines all adopt a gantry structure, which controls the leveling amount by raising and lowering the upper leveling roller, and at the same time, it rises to allow the strip steel to pass during normal feeding. However, the mutual friction between the strip steel and the lower leveling roller cannot be effectively solved. At the same time, the raising and lowering of the upper leveling roller is controlled by hydraulic pressure or elevator, and the speed is slow, which affects the efficiency of strip butt jointing.

[0020] like Figure 1-3 As shown, this embodiment provides an open leveling machine for welding pipe equipment, including a base 1, on which a leveling bracket 2 is installed, and a plurality of leveling rollers 3 are fixedly installed on the leveling bracket 2. In this embodiment, there are five leveling rollers 3, including three first leveling rollers 31 at the bottom and two second leveling rollers 32 at the top, and the two second leveling rollers 32 at the top are respectively arranged at the gaps 31 between the three first leveling rollers at the bottom, so that the leveling process of the strip steel can be realized.

[0021] In order to achieve a better strip leveling effect, in this embodiment, an auxiliary strip head leveling device 4 is further provided next to the second leveling roller 32, and the auxiliary strip head leveling device 4 is also installed on the leveling bracket 2. Specifically, the auxiliary strip head leveling device 4 includes an auxiliary strip head leveling roller 41, and the auxiliary strip head leveling roller 41 is connected to a drive motor 42, and the drive motor 42 is fixed on the leveling bracket 2. The auxiliary strip head leveling device 4 can realize all-round leveling of the strip, thereby facilitating subsequent processing.

[0022] In this embodiment, the leveling roller 3 is connected to a leveling power device 5, which includes a motor 51, which is connected to a transmission gear box 52 through a coupling, and the output shaft of the transmission gear box 52 is connected to the leveling roller 3. The transmission gear box 52 is driven by the motor 51 to rotate, thereby driving the leveling roller 3 to rotate. In this embodiment, the output shaft of the transmission gear box 52 is connected to the second leveling roller 32, the two second leveling rollers 32 at the top are active rollers, and the three first leveling rollers 31 at the bottom are driven rollers.

[0023] Furthermore, one side of the leveling bracket 2 is connected to a hydraulic drive mechanism 6, which drives one side of the leveling bracket 2 to open and close. In addition, a pinch roller 7 is arranged between the leveling roller 3 and the hydraulic drive mechanism 6, and the pinch roller 7 is connected to a pinch roller drive mechanism 8, which is fixed on the leveling bracket.

[0024] In this embodiment, a centering device 9 is also installed on the base 1 , and the centering device 9 is arranged on a side close to the hydraulic drive mechanism 6 .

[0025] In this embodiment, a feed lifting device 10 is further provided between the centering device 9 and the leveling bracket 2 , and the feed lifting device 10 is used to lift the strip for feeding.

[0026] In this embodiment, the feed lifting device 10 includes a cylinder 101, and the cylinder 101 is connected to a passive roller 102, and the passive roller 102 is used to lift the strip for feeding.

[0027] When it is necessary to level the strip head and tail in the strip coil butt jointing process, the second leveling roller 32 is opened around the rotation point by the hydraulic drive mechanism 6. After the strip head enters the leveling machine, the hydraulic drive mechanism 6 closes the second leveling roller 32 to press the strip, and the leveling power device 5 drives the second leveling roller 32 to level the strip through the transmission gear box 52. After the entire butt jointing process is completed, the second leveling roller 32 is opened around the rotation point, and the feed lifting device 10 lifts the passive roller 102 and holds up the steel strip for normal feeding.

[0028] The leveling machine installs a leveling roller 3 on a leveling machine bracket 2, and uses a hydraulic cylinder to drive a second leveling roller 32 on one side to open and close up and down, thereby completing loading and unloading. This avoids scratches on the strip during normal feeding, and also avoids wear on the lower leveling roller during normal strip feeding. While improving the overall efficiency, it also avoids the problem of wear on the leveling roller.
