Description

Technical Field

[0001] This utility model relates to the field of pipe bending machine technology, specifically a thin-walled steel pipe bending machine. Background Technology

[0002] A thin-walled steel pipe bending machine is a machine for bending thin-walled steel pipes. The working principle of the bending machine is to bend the metal pipe into various shapes using electric, hydraulic, or pneumatic principles. The bending machine can easily complete a large number of high-quality bending tasks. Compared with manual labor, the bending machine greatly improves production efficiency while shortening the time.

[0003] Existing thin-walled steel pipe bending machines, in continuous pipe bending production, do not provide uniform support at both ends of the cut section after bending, and it is also inconvenient to quickly correct the deformed position during cutting, thus affecting the production quality. To address this, we propose a thin-walled steel pipe bending machine. Utility Model Content

[0007] Preferably, a correction motor for driving the rotary seat is also fixedly installed at the rear end of the movable block.

[0008] Preferably, a first electric push rod is also fixedly installed at the rear of the movable frame, and a fixed seat is also fixedly installed between the first electric push rod and the movable frame.

[0010] Preferably, a second electric push rod is fixedly connected to one side of the movable frame, and the second electric push rod is fixed to the upper part of the pipe bending machine body.

[0011] Preferably, the pipe bending machine body is also provided with a slide groove, and the movable support seat is movably restrained and installed in the slide groove, and a positioning block is also fixedly installed in the slide groove.

[0012] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0013] In this invention, after the thin-walled steel pipe is bent by the bending seat, the fixed support and movable support on both sides of the cutting part of the thin-walled steel pipe will reduce the deformation of the thin-walled steel pipe during the cutting by the cutting disc. At the same time, after the thin-walled steel pipe is cut, the inner and outer straightening plates on both sides of the front end of the rotating seat will also move to both ends of the cutting part of the thin-walled steel pipe. Thus, the inner and outer straightening plates are driven by the straightening motor to rotate at the cutting part of the thin-walled steel pipe to correct the deformed parts of the thin-walled steel pipe after cutting, thereby ensuring the production quality of the thin-walled steel pipe.

Both the front end 206 and the outer straightening plate 207 have an opening 208 on their inner front side. The rear end of the movable block 204 is also fixedly installed with a straightening motor 209 that drives the rotating seat 205. The rear part of the movable frame 202 is also fixedly installed with a first electric push rod 210. A fixed seat 211 is also fixedly installed between the first electric push rod 210 and the movable frame 202. A binding groove 212 is also opened on one side of the movable frame 202, and the movable block 204 is movably bound in the binding groove 212. A second electric push rod 213 is also fixedly connected to one side of the movable frame 202, and the second electric push rod 213 is fixed to the upper part of the pipe bending machine body 100.

A positioning block 215 is also fixedly installed in the sliding groove 214.

[0026] Specifically, a thin-walled steel pipe bending machine is a machine for bending thin-walled steel pipes. The working principle of the bending machine is to bend metal pipes into various shapes using electric, hydraulic, or pneumatic principles. After the thin-walled steel pipe fitting 103 is bent by the bending seat 101, the fixed support seat 201 and movable support seat 203 on both sides of the cutting area of ​​the thin-walled steel pipe fitting 103 will reduce the deformation of the thin-walled steel pipe fitting 103 during cutting by the cutting disc 104. Simultaneously, after the thin-walled steel pipe fitting 103 is cut, the inner straightening plate 206 and outer straightening plate 207 on both sides of the front end of the rotating seat 205 will also move to both ends of the cutting point of the thin-walled steel pipe fitting 103. Thus, the straightening motor 209 drives the inner straightening plate 206 and outer straightening plate 207 to rotate at the cutting point of the thin-walled steel pipe fitting 103, correcting the deformed parts of the thin-walled steel pipe fitting 103 after cutting, thereby ensuring the production quality of the thin-walled steel pipe fitting 103. A rotating seat 205 is installed inside the movable block 204, mainly to ensure the stability of the inner straightening plate 206 and the outer straightening plate 207 during rotational straightening.

The first electric push rod 210 is fixedly installed on the movable frame 202, mainly for moving the inner straightening plate 206 and the outer straightening plate 207. The binding groove 212 on the movable frame 202 is mainly for binding the moving position of the movable block 204 and ensuring its stability. The second electric push rod 213 is installed on one side of the movable frame 202, mainly for switching the movement of the movable support 203 and the straightening motor 209. The positioning block 215 installed in the slide 214 is mainly for positioning the moving position of the movable support 203, thereby ensuring the accuracy of the straightening position of the inner straightening plate 206 and the outer straightening plate 207.

[0027] Working principle and usage process of this utility model:

[0028] After the thin-walled steel pipe 103 conveyed by the conveyor plate 102 is bent at the bending seat 101, the cutting plate 104 inside the bending machine body 100 will be raised to cut the thin-walled steel pipe 103. During the cutting of the thin-walled steel pipe 103, both sides of the cut part are evenly supported by the fixed support seat 201 and the movable support seat 203, respectively, thereby reducing the deformation at the cut point of the thin-walled steel pipe 103. After the thin-walled steel pipe 103 is cut by the cutting plate 104, the cutting plate 104 will move back to its original position, the conveyor plate 102 will move the remaining steel pipe backward, and the second electric push rod 213 at the upper end of the bending machine body 100 will be activated to drive the movable frame 202 to move along the slide 214. The movable support seat 203 at the front end of the movable frame 202 fits against the slide 214. After the positioning block 215 is positioned inside 214, the rotating seat 205 will be located on the outside of the cutting section of the thin-walled steel pipe fitting 103. At this time, the first electric push rod 210 at the upper end of the movable frame 202 will drive the movable block 204 to move along the binding groove 212, so as to move the inner straightening plate 206 and the outer straightening plate 207 on both sides of the rotating seat 205 in front of the movable block 204 to both sides of the cutting section of the thin-walled steel pipe fitting 103. After the inner straightening plate 206 and the outer straightening plate 207 are on both sides of the cutting section of the thin-walled steel pipe fitting 103, the straightening motor 209 will be started to drive the rotating seat 205, the inner straightening plate 206 and the outer straightening plate 207 to rotate. Thus, the production quality of the thin-walled steel pipe fitting 103 is ensured by the cyclic straightening of the inner and outer walls of the cutting section of the thin-walled steel pipe fitting 103 during the rotation of the inner straightening plate 206 and the outer straightening plate 207.
