Description

Technical Field

[0001] The utility model relates to the technical field of flat tube deformation, in particular to a flat tube deformation machine of a welded tube unit. Background Art

[0002] When the pipe is pressed and shaped, a flat tube deforming machine is used to press and deform the pipe. Generally, the pipe deforming machine presses the pipe through a roller with protrusions or grooves on the outer wall, so that the pipe is compressed and deformed according to the protrusions or grooves on the outer wall of the roller, so that the pipe is deformed into a required style. However, it is inconvenient for a general flat tube deforming machine to press and shape the bent pipe because the bent pipe is bent as a whole. When the bent pipe is pressed and deformed by the roller, if there is a support under the deformed pipe, the deformed part of the bent pipe is easy to conflict with the support and cause damage to the pipe. If there is no support under the deformed pipe, the bent pipe may tilt downward due to its own weight, affecting the compression deformation of the part of the bent pipe that has not been pressed and deformed, which is inconvenient. In addition, the process of replacing the rollers on the general flat tube deforming machine is cumbersome and inconvenient. Utility Model Content

[0026] In this embodiment, the motor shaft of the driving motor is in the shape of a polygonal column, and one end of any connecting shaft 221 is provided with a polygonal column hole movably plugged into the motor shaft of the driving motor. When in use, the user can plug the polygonal column hole on the connecting shaft 221 into the motor shaft of the driving motor, and then rotate the two adjusting screw rods 240 to drive the two deforming rollers 220 to clamp the pipe, and then start the driving motor to move the two deforming rollers 220 to clamp the pipe, so that it passes through the two deforming rollers 220 to deform. When replacing the deforming roller 220, the user The user can rotate the screw rod 270 so that the screw rod 270 drives the internal thread ring 271 to move upward, so that the internal thread ring 271 pushes the two sleeve rings 261 and the slide rod 260 to move away from each other through the two rotating rods 262, so that the two clamping plates 210 move away from each other, so that the user can remove the deformation roller 220 clamped between the two clamping plates 210, and then replace the deformation roller 220 with a new one after removing the deformation roller 220, and then rotate the screw rod 270 in the opposite direction to reset the two clamping plates 210 and clamp the two deformation rollers 220 through the clamping blocks 230 for fixing.

[0027] like Figure 3 As shown, in this embodiment, the adjustment mechanism 400 includes a U-shaped plate 410, and one end of the two arms of the U-shaped plate 410 is fixedly connected to the top surface of the bottom plate 100, one side of the two arms of the U-shaped plate 410 is provided with a guide groove 411, and a roller 440 is arranged between the two guide grooves 411, one side of the two arms of the U-shaped plate 410 is fixedly connected to two support plates, and a screw rod 420 is rotatably connected between the two support plates located on the same wall of the U-shaped plate 410, and both ends of the roller 440 are rotatably connected to a moving block 441, and one side of the two moving blocks 441 is provided with a threaded hole whose inner wall is screwed with the adjacent screw-on rod 420, the top ends of the two screw-on rods 420 pass through the adjacent support plates and are fixedly sleeved with a transmission gear 421, and a driven toothed belt 422 is rotatably sleeved between the two transmission gears 421, the top surface of the U-shaped plate 410 is fixedly connected to a power box 430 through a mounting frame, and a power motor is arranged inside the power box 430, and the motor shaft of the power motor is fixedly connected to the top end of a screw-on rod 420.

[0028] In specific implementation, when the bending tube is deformed, the end of the bent tube can be placed between the two deforming rollers 220, and then the driving motor is started to drive the adjacent deforming rollers 220 to rotate, so that the bent tube is pressed and deformed by the deforming rollers 220, and is driven to move by the deforming rollers 220, and the other parts of the bent tube are supported by the rollers 440. The user can use the control device to automatically control the opening and closing of the power motor according to the bending degree of the bent tube, so that the power motor drives the adjacent screwing rods 420 to rotate, and drives the two screwing rods 420 to rotate synchronously through the driven toothed belt 422 and the transmission gear 421, so that the two screwing rods 4 20 The roller 440 is driven by the moving block 441 to slide up and down between the two guide grooves 411. When the bent pipe is continuously fed between the two deforming rollers 220 to be compressed and deformed, since the bent pipe is in a bent state, its moving path is an arc path. If it is a special bent pipe such as an S-shaped one, the position change of the part that does not enter the two deforming rollers 220 when passing through the two deforming rollers 220 is more complicated. In addition, if the bent pipe is not restricted, its head or tail may tilt downward due to its own weight. The roller 440 moves and always supports the bent pipe, thereby facilitating the bent pipe to enter between the two deforming rollers 220 for compression molding.

[0030] In specific implementation, the pressure roller 452 is used to press the upper part of the bent pipe so that the bent pipe is always supported by the roller 440, and the weight can be applied by the counterweight block 453 so that the pressure roller 452 always clamps the bent pipe with the roller 440 to assist the bent pipe to enter between the two deforming rollers 220.

[0031] Embodiment 2

[0032] On the basis of the first embodiment, a limiting mechanism 300 is provided to limit the position of the bent pipe to prevent the bent pipe from being skewed.

[0033] like Figure 3As shown, in this embodiment, the limiting mechanism 300 includes a U-shaped frame 310, and one end of the two arms of the U-shaped frame 310 is fixedly connected to the top surface of the base plate 100, two adjusting screws 320 are rotatably connected between the two arms of the U-shaped frame 310, and one end of the two adjusting screws 320 passes through one arm of the U-shaped frame 310 and is fixedly sleeved with a main gear 321, a transmission toothed belt 322 is rotatably sleeved between the outer walls of the two main gears 321, and one end of an adjusting screw 320 is fixedly connected to a crank, two splints 330 are arranged between the two arms of the U-shaped frame 310, and screw holes are opened at both ends of the two splints 330, and the inner walls of the two screw holes on the same splint 330 are respectively screwed with the outer walls of the two adjusting screws 320.

Both the two adjusting screw rods 320 are positive and negative threaded screw rods, so that when the two adjusting screw rods 320 rotate, they can drive the two clamping plates 330 to move toward or away from each other. Then the user can turn the crank to drive the adjacent adjusting screw rods 320 to rotate, and drive the two adjusting screw rods 320 to rotate synchronously through the two main gears 321 and the transmission toothed belt 322, so that the two clamping plates 330 are close to each other, limit the bent pipe, and prevent the bent pipe from being skewed.
