Description

Technical Field

[0001] This utility model belongs to the field of steel pipe straightening machines and relates to a straightening roller for steel pipe straightening machines. Background Technology

[0002] Application CN201420025021.4 discloses a steel pipe straightening machine, including a base, a movable support mechanism, and a movable pressure mechanism. The movable support mechanism supports both ends of the steel pipe and moves linearly on the base. The movable support mechanism rotates the steel pipe, causing the portion with the largest bending radius to rotate to a higher position. The movable pressure mechanism presses down on the bent portion. The steel pipe straightening machine repeats the above process to complete the straightening. However, the above-mentioned prior art can only straighten one bent portion at a time, which is slow. Furthermore, adjacent portions may deform during the straightening process. Therefore, existing steel pipe straightening machines suffer from low straightening efficiency. Utility Model Content

[0003] This invention addresses the problem of low straightening efficiency in existing steel pipe straightening machines by providing a straightening roller for a steel pipe straightening machine.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a straightening roller for a steel pipe straightening machine, including a lower base, an upper base connected above the lower base, two straightening roller mechanisms installed on the upper base, a steel pipe passing through the two straightening roller mechanisms, the straightening roller mechanism including a horizontally arranged lifting machine, the lifting machine including a linear movable end, the linear movable end being connected to a roller frame, and the roller frame being rotatably connected to a straightening roller for overlapping with the steel pipe.

[0005] Preferably, the elevator is connected to a speed reducer, and a motor is connected to the end of the speed reducer away from the speed reducer.

[0006] Preferably, the upper base is provided with rails on both sides, and the rails are slidably connected to the roller frame.

[0007] Preferably, the straightening roller is arranged vertically.

[0008] Preferably, the lower base is hollowed out.

[0009] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0010] Multiple components of this invention are mounted on a steel pipe straightening machine. Driven by a motor, straightening rollers clamp the steel pipe from both sides, thus straightening multiple bent sections. Furthermore, existing straightening machines require the bent section of the steel pipe to be rotated to a high position before being pressed down. With this invention, the steel pipe only needs to be rotated to a horizontal position; there is no need to pay attention to whether the rotation is in the correct or reverse direction. Existing straightening machines require control of the downward pressure to prevent insufficient force leading to incomplete straightening or excessive force causing reverse bending. Since this invention uses two straightening rollers moving towards the center, there is no need to control the pushing force of the lifting mechanism. Attached Figure Description

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] like Figure 1 , Figure 2As shown, to solve the problem of low straightening efficiency in existing steel pipe straightening machines, this utility model provides a straightening roller for steel pipe straightening machines, which replaces the existing moving pressure mechanism. Multiple rollers of this utility model are arranged along a straight line on the steel pipe straightening machine. This utility model includes a lower base 1, with an upper base 2 connected above it. Two straightening roller mechanisms 3 are installed on the upper base 2. A steel pipe 4 passes between the two straightening roller mechanisms 3. The straightening roller mechanism 3 includes a horizontally arranged lifting platform 31, which includes a linear movable end 32 connected to a roller frame 33. The roller frame 33 is rotatably connected to a straightening roller 34 for overlapping with the steel pipe 4.

[0018] The method of using this utility model is as follows: After placing both ends of the steel pipe 4 on the steel pipe 4 straightening machine, the steel pipe straightening machine drives the steel pipe 4 to rotate. In the prior art, it is necessary to rotate the bent part to a high position, but in this utility model, it is necessary to rotate the bent part to a horizontal position. It is not necessary to pay attention to whether the rotation is horizontal in the forward or reverse direction. Then, start this utility model, and the lifting machine 31 pushes the roller frame 33 to move upward to the center of the base 2, so that the straightening roller 34 clamps the steel pipe 4 from both sides. When multiple of this utility model are set, the steel pipe 4 can be straightened, and multiple bent parts in the horizontal direction can be straightened at one time, thus improving the straightening efficiency. Rotate the steel pipe and repeat the above straightening process until the straightening requirements of the steel pipe 4 are met.

[0019] Furthermore, the elevator 31 is connected to a reducer 35, and a motor 36 is connected to the end of the reducer 35 away from the reducer 35.

[0020] Furthermore, rails 21 are provided on both sides of the upper base 2, and the rails 21 are slidably connected to the roller frame 33, so that the roller frame 33 can move stably along a straight line.

[0021] Furthermore, the straightening roller 34 is set vertically.

[0022] Furthermore, the lower base 1 is hollowed out to reduce its weight.

[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
