Description

Welded pipe shaping and straightening device

technical field

The utility model relates to a welded pipe production equipment, in particular to an online leveling and straightening device for welded pipes.

Background technique

In the prior art, the production of welded pipes is generally processed by roll forming, which is welded and formed at its closed position. Specifically, it passes the strip through the feeding device, leveling device, shear butt welding device, and roll forming in sequence. device, welding device, planing device, straightening device and online cutting device, so that the strip is gradually rolled into a tubular shape, and then welded, planed and cut to obtain a welded pipe. After welding and forming, it is necessary to straighten the welded pipe to correct the deformation of the roll bending and welding process, so that the welded pipe has good roundness and straightness.

The current welded pipe shaping device mainly includes a number of flat roller pairs and vertical roller pairs, and the flat roller pairs and vertical roller pairs are arranged alternately. It is squeezed and deformed by each group of shaping rollers in turn to make it round, smooth and straight. Its shortcoming is that the existing shaping roller pair can only maintain its state of being a flat roller pair or a vertical roller pair. As a result, the number of shaping roller pairs required for shaping and straightening is large, and the manufacturing and use costs are high.

Utility model content

The purpose of the utility model is to provide a welded pipe shaping and straightening device, which can adjust the angle and height of the shaping roller pair on-line, so as to reduce the consumption of the shaping roller pair.

The device also includes a base. A frame is set upright on the base. A rectangular chute is provided on the frame. A main slider is arranged in the chute. The upper end of the frame is threaded with a main adjustment screw. The screw goes through the upper end of the frame and extends into the rectangular chute. The lower end of the main adjusting screw is rotatably connected with the main slider. The center of the main slider is rotatably provided with a rotor. The center of the rotor is provided with a horizontal through hole. The worm gear is engaged with the worm gear and is provided with a worm screw, which is rotatably installed on the main slider. There are two guide grooves located on the same axis on the support plate, and auxiliary sliders are arranged in the guide grooves, and the two ends of the roller shaft are installed on the corresponding auxiliary sliders. It is connected with the gland on the corresponding side, and the gland on at least one side is screwed with an auxiliary adjusting screw rod, and the auxiliary adjusting screw rod is rotatably connected with the auxiliary sliding block.

The utility model is used in a welded pipe production line. It is necessary to set multiple groups on the same axis. By rotating the worm, the worm wheel drives the rotor to rotate, and then drives the shaping roller pair to rotate as a whole, so that part of the shaping roller pair is a flat roller pair, and some shaping roller pairs are For the vertical roller pair, the flat roller and the vertical roller pair can be arranged alternately. The overall height of the main slider can be adjusted through the main adjusting screw, and the gap between the two shaping rollers of the shaping roller pair can be adjusted through the auxiliary adjusting screw. Under the extrusion of the machine, the welded pipe is rounded and straightened to meet the design requirements. The device has versatility and does not need to specially design independent pairs of flat rollers and vertical rollers. It can be used as both a pair of flat rollers and a pair of vertical rollers, which can simplify the overall design. During the working process, the angle of the rotor can also be adjusted at any time according to the needs of shaping, not only the roller axis is limited to the horizontal and vertical directions, but can be at any angle, so that targeted adjustments can be made at positions with large deformation. The overall shaping passes are reduced, that is to say, the amount of shaping roller pairs can be reduced, the cost is saved, and the length of the production line is shortened. The device can realize online adjustment without stopping the machine.

The utility model can have the following two specific schemes: one, one of the two auxiliary sliders on each support plate is fixedly connected to the gland on the corresponding side, and the other auxiliary slider is connected to the gland on the corresponding side through the The auxiliary adjusting screw is connected. One of the auxiliary sliders is fixed, and the gap between the shaping rollers is adjusted through the movement of the other auxiliary slider. Second, the two auxiliary sliders on each support plate are connected to the glands on the corresponding sides via the auxiliary adjustment screw; thus the position of the auxiliary sliders can be adjusted bidirectionally.

In order to facilitate the positioning of the rotor and facilitate the fixed installation of the support plate, a radially protruding step is provided at the end of the rotor, one side of the step is attached to the main slider, and the support plate is connected to the other side of the step.

As a further improvement of the present invention, the main slider and the auxiliary slider are roughly rectangular. The rectangular main slider and auxiliary slider are easy to manufacture and install, and have good direction when adjusting.
