Description

Technical Field

[0001] The utility model relates to pipeline production auxiliary equipment, in particular to a pipeline production bending device. Background Art

[0002] In order to meet the needs of actual applications, it is often necessary to bend the pipes during production or use. At present, there are many types of pipe bending equipment on the market, such as: a pipe bending device disclosed in Chinese patent CN219820621U, and a pipe bending device disclosed in Chinese patent CN220387559U. Through the provided pressure rod, base plate and clamping arm, when bending the pipe, the pressure rod rotates upward, the sliding sleeve drives the long rod to rotate, thereby driving the clamping arm to rotate. When the inner wall of the U-shaped clamp is aligned with the side wall of the cavity, the pipe is inserted into the inner wall of the U-shaped clamp and the side wall of the cavity, and then the U-shaped clamp is pushed to make the slider slide in the slide groove, driving the U-shaped clamp to move to the required position, pressing the pressure rod downward to make the sliding sleeve move to the right, and the clamping arm drives the pipe to rotate, thereby bending the pipe to a specific curvature. However, the use of this equipment requires manual force to bend.

[0017] like Figure 1-2 As shown, a bending device for pipe production includes a frame and a pipe conveying mechanism and a pipe bending mechanism disposed on the frame. The pipe conveying mechanism includes a support frame for supporting the pipe, a pushing mechanism for driving the pipe to move along the support frame, and a clamping mechanism for bending and positioning. The pipe bending mechanism includes a support base 6, a rotating table 7 disposed on the support base 6, a rotating shaft 9 rotatably connected to the rotating table 7, a bending motor 8 for driving the rotating shaft 9, a guide wheel 10 rotatably connected to the upper end of the rotating shaft 9, a bending bracket 15 transmission-connected to the rotating shaft 9, and a bending stopper 11 disposed on the bending bracket 15. The bending device for pipe production has the advantages of scientific design, ease of use, and good bending effect. During use, the rotating shaft is driven by the motor to rotate, which drives the bending bracket and the bending stopper to move. The bending stopper squeezes the pipe to bend it.

[0018] In other embodiments, one end of the bending stopper is also connected to a rotating shaft, the lower end of the rotating shaft is rotatably connected to the support seat, and a pressure wheel is provided on the bending bracket, and the pressure wheel is tangent to the bending stopper (the bending stopper is located between the pressure wheel and the guide wheel). During use, the motor drives the rotating shaft to rotate, and the bending bracket and the pressure wheel also move around the rotating shaft, and the pressure wheel presses the bending stopper to move the bent pipe.

[0019] In one embodiment, the support frame comprises several sets of parallel inverted V-shaped frames, each comprising two inclined support rods 1 connected at the top and middle by transverse connecting rods 2, with longitudinal connecting rods 3 provided at the lower ends of the support rods 1. The upper sides of the transverse connecting rods 2 at the top of each inverted V-shaped frame are connected by a pipe guide plate 4, which has a V-shaped groove in the middle. During use, the pipe to be bent is placed in the V-shaped groove of the pipe guide plate.

[0020] In one embodiment, the pushing mechanism includes a first telescopic rod 5, the telescopic end of which is provided with a spherical pushing head, and the fixed end of the first telescopic rod 5 is fixedly connected to the inverted V-shaped frame farthest from the pipe bending mechanism. During use, the first telescopic rod is extended to push the pipe to be bent to the pipe bending mechanism for bending. In other embodiments, other pushing mechanisms of the prior art may be adopted, such as: a clamping mechanism, a screw nut and a transmission screw. When the pipe needs to be pushed forward, the clamping mechanism clamps the pipe, and the motor drives the screw to move the clamping mechanism, as long as it can meet the feeding requirements.

[0021] In one embodiment, the clamping mechanism includes a fixed clamping block 14 and a movable clamping block 13 arranged opposite to each other. The fixed clamping block 14 is fixedly connected to the support frame, and the movable clamping block 13 is connected to the telescopic end of the second telescopic rod 12. The fixed end of the second telescopic rod 12 is fixedly connected to the support frame and / or the support base 6. The fixed clamping block 14 and the movable clamping block 13 are respectively provided with an arc groove on the opposite side, and a channel is formed between the two arc grooves to accommodate the pipe to be bent. During use, the movable clamping block is driven to move closer to or away from the fixed clamping block by the extension and contraction of the second telescopic rod to achieve clamping or loosening. Specifically, the telescopic end of the second telescopic rod can be directly connected to the movable clamping block. When directly connected, the extension and contraction trajectory of the second telescopic rod and the movement trajectory of the movable clamping block are on the same straight line. In order to save space, the extension and contraction end of the second telescopic rod can also be connected to the movable clamping block via a hinged connecting rod, so that the extension and contraction trajectory of the second telescopic rod is perpendicular to the movement trajectory of the movable clamping block. As long as the movable clamping block and the fixed clamping block can be driven to perform clamping and loosening operations, it can be used.

[0022] In one embodiment, the guide wheel 10 is provided with an annular groove. A positioning groove is formed on the side of the bending stopper 11 adjacent to the guide wheel 10, corresponding to the annular groove. The positioning groove and the annular groove form a channel for accommodating the pipe to be bent. During use, the positioning groove and the annular groove sandwich the pipe, facilitating the bending operation.

[0023] The above embodiments can be combined with each other.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and not to limit it; although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents; without departing from the spirit of the technical solution of the utility model, they should all be included in the scope of the technical solution for protection of the utility model.
