Description

Technical Field

[0001] This application relates to the field of steel pipe processing. Specifically, it relates to a steel pipe straightening device for steel pipe processing. Background Art

[0002] Existing steel pipes are generally straightened mechanically, allowing the steel pipe to pass through the roller of a cam structure in sequence. During the process of the steel pipe passing through the roller, the bent part of the steel pipe is straightened. However, when the steel pipe enters between the rollers, the rollers extrude the outer wall of the contact part of the bent part of the steel pipe, resulting in a relatively large pressure on one side of the steel pipe wall and easily causing deformation of the steel pipe wall.

[0003] The structure of the product can refer to a steel pipe straightening device disclosed in the Chinese patent document publication number: CN218049719U, which includes a workbench. A number of arc-shaped blocks are installed on the upper end surface of the workbench. A number of heating semi-rings are installed between two adjacent arc-shaped blocks. Support frames are symmetrically arranged on the upper end surface of the workbench in a mirror image manner. A lead screw is horizontally arranged between the two support frames. A bidirectional motor is installed on the support frame near the left end of the lead screw. A bearing is provided on the support frame near the right end of the lead screw. The lead screw passes through the bearing. A slider is installed on the lead screw. An electric push rod and an N-shaped frame are sequentially installed at the bottom of the slider. A connecting rod is horizontally arranged between the N-shaped frames. A roller is rotatably connected to the connecting rod. An arc-shaped groove is provided on the roller.

[0004] In the above structure, the outer wall of the bent position of the steel pipe is extruded and straightened by the roller, resulting in the problem that the steel pipe wall is easily deformed.

[0005] Therefore, a steel pipe straightening device for steel pipe processing that avoids deformation of the pipe wall is needed. Summary of the Utility Model

[0030] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0031] Referring to Figures 1-4 , a steel pipe straightening device for steel pipe processing includes: a frame 100, guide rollers 101, a driving motor 102, a straightening frame 103, and straightening wheels 104. Two support side plates 105 arranged along the direction of steel pipe insertion are fixedly connected to the frame 100. The straightening frame 103 is rotatably arranged between the two support side plates 105, and the rotation axis is consistent with the axis of the inserted steel pipe.

[0032] In one embodiment, an adjustment wheel 106 is fixedly connected to the straightening frame 103, and an adjustment motor 107 is fixedly connected to the frame 100. The output end of the adjustment motor 107 is in transmission connection with the adjustment wheel 106 through a transmission belt. By the adjustment motor 107 outputting power and driving the adjustment wheel 106 to rotate through the transmission belt, the straightening frame 103 is deflected, facilitating the straightening of the steel pipe bent in different directions.

[0033] A straightening groove 108 for the steel pipe to be inserted is formed in the straightening frame 103, and both ends of the straightening groove 108 are through along the direction of steel pipe insertion.

[0034] A plurality of cylinders 109 are fixedly connected to the straightening frame 103. One end of the telescopic rod of the cylinder 109 is inserted into the straightening groove 108, and the straightening wheel 104 is rotatably arranged at one end of the telescopic rod of the cylinder 109.

[0035] In one embodiment, the plurality of cylinders 109 are arranged along the direction of steel pipe insertion.

[0036] A vertical plate 110 is fixedly connected to the frame 100. The vertical plate 110 is arranged at the end position of the frame 100 along the direction of steel pipe insertion. A connecting rod 111 arranged along the direction of steel pipe insertion and extending into the straightening groove 108 is fixedly connected to the vertical plate 110. The connecting rod 111 is a rod made of plastic material and can undergo a certain deformation. An installation block 112 is slidably arranged on the connecting rod 111. A moving motor 121 is fixedly connected to the vertical plate 110. The output end of the moving motor 121 is fixedly connected to a screw rod 113 arranged in the same direction as the connecting rod 111. The screw rod 113 passes through the installation block 112 and is in threaded connection with the installation block 112. By the moving motor 121 outputting power to drive the screw rod 113 to rotate, the installation block 112 slides along the connecting rod 111.

[0037] A plurality of hydraulic cylinders 114 distributed circumferentially are arranged on the installation block 112, and one end of each hydraulic cylinder 114 is fixedly connected to a support block 115.

[0038] In one embodiment, one side surface of the support block 115 away from the installation block 112 is set as an arc surface structure that fits the inner wall of the steel pipe.

[0039] In one embodiment, two guiding frames 116 are further provided on the rack 100 and are respectively located on both sides of the straightening frame 103. A sliding groove 117 is formed in the guiding frame 116, and two vertically distributed sliders 118 are slidably connected in the sliding groove 117. The guiding roller 101 is rotatably arranged on the slider 118. There is a gap for the steel pipe between the two vertically distributed guiding rollers 101. An elastic member 119 is arranged between the slider 118 and the guiding frame 116, and the elastic member 119 is set as a spring, so that the two guiding rollers 101 have a tendency to approach each other, thereby clamping the steel pipe between the two guiding rollers 101. The output end of the driving motor 102 fixed on the rack 100 is connected to one of the guiding rollers 101 through belt drive. A tensioning structure is arranged on the belt to prevent the belt from slipping when the guiding roller 101 moves.

[0040] In one embodiment, a plurality of support bolts 120 distributed circumferentially along the axis of the steel pipe are threadedly connected to the support side plate 105. The mounting block 112 is threadedly arranged on the straightening frame 103 and is arranged on both sides of the axis of the steel pipe. One end of the support bolt 120 is inserted into the straightening groove 108. When guiding and moving in the straightening groove 108 through the guiding roller 101, the connecting rod 111 is inserted into the steel pipe, and at the same time, the mounting block 112 is located inside the steel pipe. By rotating the support bolt 120, the head end of the support bolt 120 abuts against the outer wall of the steel pipe.
