Description

Technical Field

[0001] This utility model relates to the field of welded pipe processing technology, specifically to a cutting device for irregularly shaped welded pipes. Background Technology

[0002] Welded steel pipes are steel pipes with seams on their surface, made by bending steel strips or plates into round, square, or other shapes and then welding them together. The raw materials used for welded steel pipes are steel plates or strips. Furnace-welded pipes can be used as water and gas pipes, while large-diameter straight-seam welded pipes are used for high-pressure oil and gas transportation. Spiral welded pipes are used for oil and gas transportation, pipe piles, bridge piers, etc.

[0003] A search revealed that patent document CN210703011U discloses a spiral welded pipe cutting device. The device includes a displacement adjustment assembly, a cutting torch clamping component, and a spiral welded pipe positioning assembly. The displacement adjustment assembly includes an X-direction displacement adjustment mechanism, a Y-direction displacement adjustment mechanism, a Z-direction displacement adjustment mechanism, and a support platform. The spiral welded pipe positioning assembly includes a base, a first support, a second support, a first roller, and a second roller. In use, the spiral welded pipe is first placed between the first and second rollers. Then, the X-direction, Y-direction, and Z-direction displacement adjustment mechanisms are adjusted so that the nozzle of the cutting torch, held by the cutting torch clamping component, is aligned with the cutting line of the spiral welded pipe, allowing the cutting torch to cut the pipe.

[0004] However, the rollers in this welded pipe cutting device can only rotate circular welded pipes. When cutting some irregularly shaped welded pipes, such as square, triangular, and oval shapes, the rollers cannot drive the irregularly shaped welded pipes to rotate effectively, which reduces the cutting efficiency. Therefore, an irregularly shaped welded pipe cutting device is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a non-circular welded pipe cutting device, which has advantages such as easy and stable clamping and rotation. It solves the problem that in existing welded pipe cutting devices, the roller can only rotate circular welded pipes, and when cutting some non-circular welded pipes, the roller cannot drive the non-circular welded pipes to rotate effectively, thus reducing the cutting efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a non-circular welded pipe cutting device, comprising a base plate, a bracket fixedly installed at the bottom of the base plate, a mounting frame provided on the upper side of the base plate, a cutting machine fixedly installed on the outer side of the mounting frame, and a rotating mechanism provided on one side of the cutting machine;

[0007] The rotating mechanism includes a connecting plate connected to a base plate, a fixed cylinder fixedly connected to the end of the connecting plate, a drive motor fixedly mounted on the outer wall of the connecting plate, a transmission gear fixedly mounted on the output shaft of the drive motor, a driven gear meshing with the outer side of the transmission gear, a rotating cylinder fixedly connected to the inner side of the driven gear, a bench vise fixedly connected to one end of the rotating cylinder, the other end of the rotating cylinder extending into the interior of the fixed cylinder, and a support bearing installed between the rotating cylinder and the fixed cylinder.

[0008] Furthermore, there are two supports, which are symmetrically distributed on both sides of the bottom of the base plate. A hydraulic rod is hinged to the side wall of the support closest to the rotating mechanism.

[0009] Furthermore, the output shaft of the hydraulic rod is hinged to the bottom of the connecting plate, and the end of the connecting plate away from the fixed cylinder is hinged to the side wall of the bottom plate.

[0010] Furthermore, the outer wall of the rotating cylinder is tightly fitted with the inner ring of the supporting bearing, and the inner wall of the fixed cylinder is tightly fitted with the outer ring of the supporting bearing.

[0011] Furthermore, a fixing seat is fixedly installed on the top of the base plate, and an mounting plate is fixedly connected to the outside of the fixing seat.

[0012] Furthermore, an electric push rod is fixedly installed on the outer side of the mounting plate, and the output shaft of the electric push rod is fixedly connected to the mounting bracket.

[0013] Furthermore, a guide rod is fixedly connected to the side of the mounting bracket near the mounting plate. The guide rod passes through the inner side of the mounting plate and the fixing seat, and the outer wall of the guide rod slides in cooperation with the inner side of the fixing seat. There are two guide rods.

[0014] Compared with the prior art, this utility model provides a cutting device for irregularly shaped welded pipes, which has the following advantages:

[0015] 1. This irregular welded pipe cutting device uses a bench vise to clamp and fix the irregular welded pipe. With the cooperation of the drive motor, transmission gear, driven gear, and rotating cylinder, the bench vise can be driven to rotate, thereby driving the irregular welded pipe to rotate. This ensures the efficient cutting of irregular welded pipes by the cutting machine, improves processing efficiency, and solves the problem that the rollers in existing welded pipe cutting devices can only rotate round welded pipes. When cutting some irregular welded pipes, the rollers cannot drive the irregular welded pipes to rotate effectively, which reduces the cutting efficiency.

[0016] 2. This irregularly shaped welded pipe cutting device, driven by a hydraulic rod, allows for easy adjustment of the angle of the rotating mechanism, thereby facilitating the adjustment of the fixed height of the welded pipe and improving ease of use. Attached Figure Description
