Description

Technical Field

[0001] This utility model relates to the technical field of steel pipe production equipment, and in particular to an automatic cutting machine for weld scar strips inside steel pipes. Background Technology

[0002] During the welding process of steel pipe production, weld spatter forms both inside and outside the weld. This spatter is typically scraped off using a scraper, leaving a continuous weld spatter strip. This strip, especially the internal weld spatter strip, needs to be cut promptly to ensure the normal transport, handling, and transfer of the steel pipe. Previously, without specialized cutting devices, the weld spatter strip was manually hooked out of the pipe and then cut. This method was not only time-consuming and labor-intensive but also posed safety hazards, easily injuring operators. To address these problems, our company has independently developed an automatic weld spatter cutting machine for steel pipes. This machine automatically cuts weld spatter strips, significantly saving time and manpower, and completely eliminating safety hazards. Summary of the Invention

The upper shear block is fixed to the knife handle. The knife handle is fixed to the connecting sleeve. The connecting sleeve is located on the rotating shaft. The rotating shaft is located on the rotating shaft seat and is connected to the power device.

[0005] Furthermore, a transmission sprocket is provided on the rotating shaft.

[0006] Moreover, the power unit is a cycloidal pinwheel reducer with a drive sprocket mounted on it.

Detailed Implementation

[0013] The present invention will be further described in detail below through specific embodiments. The following embodiments are only descriptive and not limiting, and should not be used to limit the protection scope of the present invention.

[0014] An automatic cutting machine for weld scar strips inside steel pipes consists of a base 3, a limiting device 1, a shearing device 4, and a power unit 5. The limiting device and the shearing device are both located on the top surface of the base, and the power unit is connected to the shearing device via a transmission.

[0015] The shearing device consists of a lower shear block 13, a lower shear block seat 12, an upper shear block 17, a knife handle 16, a connecting sleeve 15, a rotating shaft 11, and a rotating shaft seat 10. The lower shear block seat is coaxially and laterally arranged on the top surface of the machine base with the conveying roller. The lower shear block is coaxially fixed on the lower shear block seat, the upper shear block is fixed on the knife handle, the knife handle is fixed on the connecting sleeve, the connecting sleeve is arranged on the rotating shaft, and the rotating shaft is arranged on the rotating shaft seat and is connected to the power device for transmission.

[0016] A rotating shaft, on which a transmission sprocket 9 is mounted.

[0017] The power unit is a cycloidal pinwheel reducer with a drive sprocket mounted on it. The drive sprocket and the transmission sprocket are connected by a chain drive.

[0018] The limiting device consists of a limiting roller bracket 7, a side limiting roller 6, and an upper limiting roller 8. The limiting roller bracket is fixed on the machine base. The side limiting rollers are symmetrically and vertically arranged on both sides of the conveying roller on the machine base. The upper limiting roller is horizontally arranged above the conveying roller on the upper part of the limiting roller bracket.

[0019] The working principle of this utility model: On the steel pipe production line, after steel pipe 2 is cut by the rotary saw, the internal weld scar strips inside the steel pipe remain connected. When the cut steel pipe is conveyed forward by the conveyor roller 14, it will continue to be conveyed forward at a relatively fast speed, creating a gap between the preceding and following steel pipes. At this time, the production line control mechanism will control the power unit to start. After the cycloidal pinwheel reducer starts, it drives the cutter handle and the upper shear block fixed on it to rotate and rotate one revolution through the drive sprocket, chain, transmission sprocket, rotating shaft, and connecting sleeve. The upper shear block and the lower shear block are tangent, thus cutting off the internal weld scar strips.

[0020] Although embodiments and drawings of the present invention have been disclosed for illustrative purposes, those skilled in the art will understand that various substitutions, variations and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
