Description

Technical Field

[0002] During the process of forming a spiral pipe by a steel pipe through a spiral coil pipe machine, since the spiral of the steel pipe is continuously pushed out by the rotating head of the coil pipe machine, a supporting device is required to support the spiral pipe. At the same time, as a flexible structural component, while the supporting device provides support for the spiral pipe, it needs to rotate synchronously to prevent the pitch of the spiral pipe from being compressed or stretched due to resistance. Therefore, a spiral coil pipe supporting rack capable of matching the discharging speed and rotation of the spiral pipe is needed to ensure the forming quality of the spiral coil pipe. Summary of the Invention

By adjusting the angle of the supporting rack, the discharging direction of the spiral pipe can be adapted. At the same time, the angle and rotation speed of the inclined supporting rollers are matched with the pitch and discharging speed of the spiral pipe, and will not compress or stretch the pitch of the spiral pipe, thereby preventing the formed spiral pipe from deforming and ensuring the consistency of the pitch of the spiral pipe.

[0005] It is further characterized in that: the supporting rollers are arranged on a supporting roller bracket, and the supporting roller bracket is arranged on the supporting rack through a plurality of lifting devices.

Adjusting the angle of the supporting rack can achieve coarse adjustment to adapt to the pitch, and adjusting the angle of the supporting rollers can achieve fine adjustment to adapt to the pitch.

[0008] Preferably: One end of the fixed rod and the angle adjusting rod is connected by a connecting piece; the angle adjusting rod is a lead screw, which is threadedly connected to the connecting piece; a rotating handwheel is provided on the angle adjusting rod. By rotating the handwheel to drive the lead screw to rotate, the staggered position of the fixed rod and the angle adjusting rod changes, driving the inclination angle of the material supporting roller to change, realizing fine adjustment of the pitch matching, so that the product can achieve an accuracy of pitch ±1 mm.

[0009] Preferably: The driving device is a driving rod driven by a servo motor to rotate, and the driving rod is arranged parallel to the fixed rod and the angle adjusting rod; a plurality of belt pulleys are provided on the driving rod, and the material supporting roller is connected to the belt pulley of the driving rod.

[0010] Preferably: The fixed rod and the angle adjusting rod are connected and positioned by a connecting piece; an adjusting lead screw is arranged between the two connecting pieces on both sides, which is used to adjust the distance between two rows of material supporting rollers. By adjusting the distance between two rows of material supporting rollers, the height difference between the two rows of material supporting rollers is realized to adapt to the universality of the left-handed and right-handed spiral tube products.

[0011] Preferably: The surface of the material supporting roller is covered with a flexible material. The part in contact with the spiral tube product uses a flexible material to ensure that the outer surface of the product will not cause hard abrasion or scratching.

[0012] Preferably: The frame and the material supporting frame are driven to rotate by a cylinder to realize rough adjustment of the angle of the material supporting frame.

[0013] Preferably: An angle measurement window is arranged between the frame and the material supporting frame, and the angle between the frame and the material supporting frame can be visually confirmed through the angle measurement window.

[0014] Through the adjustment of the angle of the material supporting frame, the present invention realizes rough angle adjustment, and through the adjustment of the angle of the material supporting roller, it realizes fine angle adjustment to adapt to the discharging direction of the spiral tube. At the same time, the inclination angle and rotation speed of the material supporting roller are matched with the pitch and discharging speed of the spiral tube, and will not cause compression or stretching of the pitch of the spiral tube, thereby preventing the deformed spiral tube after coiling and ensuring the consistency of the pitch of the spiral tube. The structure of the present invention is simple, the pitch control is accurate, the universality is strong, and the workload of manual shaping of the spiral tube in the later stage is reduced.

[0015] Figure 1 It is a schematic structural diagram of the present invention. Detailed Embodiment

[0016] Such asFigure 1 As shown in the figure, a spiral coil pipe supporting rack includes a rack 1 and a supporting rack 2 arranged on the rack 1. One end of the supporting rack 2 is pivotally connected to the rack 1, and the other end is driven by a cylinder 21 to swing around the pivot on the rack 1. An angle measurement window 11 is provided between the rack 1 and the supporting rack 2, and through the angle measurement window 11, the angle between the rack 1 and the supporting rack 2 can be visually confirmed.

[0017] Two rows of parallel driving rods 22, fixed rods 23 and angle adjusting rods 24 are arranged on the supporting rack 2. One ends of the fixed rod 23 and the angle adjusting rod 24 are connected by a connecting piece 26. The angle adjusting rod 24 is a lead screw, threadedly connected to the connecting piece 26, and a rotating handwheel 25 is arranged on the angle adjusting rod 24. A plurality of supporting rollers 27 are arranged on a supporting roller base 28, and both ends of the supporting roller base 28 are movably connected to the fixed rod 23 and the angle adjusting rod 24. By rotating the handwheel 25 to adjust the staggered positions of the fixed rod 23 and the angle adjusting rod 24, the angle of the supporting roller 27 is adjusted, driving the inclination angle of the supporting roller 27 to change, realizing fine adjustment of pitch matching, so that the product can reach an accuracy of pitch ±1 mm. The driving rod 22 is driven to rotate by a servo motor 30, a plurality of belt pulleys 29 are arranged on the driving rod 22, and the supporting roller 27 is belt-connected to the driving rod 22. A plurality of supporting rollers 27 are driven to rotate synchronously by the driving rod 22. The surface of the supporting roller 27 is covered with a rubber material to ensure that the outer surface of the product will not cause hard abrasion or scratching.

[0018] The two rows of supporting rollers 27, driving rods 22, fixed rods 23 and angle adjusting rods 24 are integrally arranged on the supporting rack 2 through a plurality of lifting devices. Through the lifting devices. The lifting device is a lead screw lifting device 31, which is driven by a servo motor 30 through a worm and worm gear device to lift synchronously. Through the lifting device, the height of the supporting roller is matched with the height of the spiral pipe discharging. By matching the servo motor and the lead screw lifting device, the accuracy of height adjustment can be achieved.

[0019] The fixed rod 23 and the angle adjusting rod 24 are connected and positioned by a connecting piece 26. An adjusting lead screw 33 is arranged between the connecting pieces 26 on both sides, which is used to adjust the distance between the two rows of supporting rollers 27. By adjusting the distance between the two rows of supporting rollers 27, the height difference between the two rows of supporting rollers 27 is realized to adapt to the universality of the left-handed and right-handed spiral pipe products.

[0020] When the present invention is used, first, the supporting rack 2 is driven to rotate by the cylinder 21 to roughly adjust the angle of the supporting rack 2 to adapt to the discharging direction of the spiral pipe. The height of the supporting rack 2 is adjusted to match the height of the spiral pipe 3 through the lifting device. After the spiral pipe 3 product enters the supporting rack 2, the angle and speed of the supporting roller 27 are finely adjusted through the handwheel 25 to match the pitch of the spiral pipe 3, so that after the workpiece is separated from the coiling machine, it automatically remains unchanged in shape and maintains an accurate pitch, reducing the workload of manual shaping of the spiral pipe 3 in the later stage.
