Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing equipment, specifically to a high-efficiency steel pipe slitting device. Background Technology

[0002] Before use, long steel pipes sometimes need to be cut to a fixed length. Current methods for fixed-length cutting include: some involve marking a single pipe to a predetermined length before cutting it with a cutting machine, which is inefficient; others use a clamping mechanism to hold one or more pipes and push them forward to a fixed position under the cutting machine for fixed-length cutting. However, with this method, as the pipes are continuously shortened at the front end, the clamping mechanism needs to be released, moved, and re-clamped, affecting work efficiency. Furthermore, the working area of ​​the cutting saw blade on current cutting machines is generally open for cutting purposes, posing a safety risk of accidental injury. Therefore, it is necessary to improve the steel pipe cutting device. A solution that allows for clamping multiple pipes at once without releasing the clamping mechanism mid-cut, and enables fixed-length cutting by moving the cutting machine, while also providing complete protection for the cutting saw blade when not in operation with a protective cover, would improve cutting efficiency and reduce safety risks. This is the problem to be solved in this case. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model discloses a high-efficiency steel pipe slitting device, including a clamping assembly and a cutting assembly. The clamping assembly is equipped with several sets of clamping parts that can simultaneously clamp several steel pipes and a linear module that can drive them to move laterally. The cutting assembly is equipped with a circular saw with a circular saw blade, a protective cover covering the circular saw blade, and a lifting frame that can drive the circular saw to move longitudinally. The protective cover is equipped with a fixed cover and a movable cover. The movable cover can rotate upward and can be hidden in the cavity of the upper fixed cover, so that the lower half of the circular saw blade is exposed. This invention improves the steel pipe cutting device by using several sets of clamping components to simultaneously clamp several steel pipes and move them laterally. The movable cover of the cutting assembly can rotate upwards and retract into the cavity of the upper fixed cover, exposing the lower half of the circular saw blade to cut several steel pipes. Furthermore, a lifting frame drives the circular cutter to move longitudinally to a fixed length, allowing it to cut the next section of several steel pipes, thus achieving efficient cutting without needing to release the clamping components midway. In non-working mode, the movable cover rotates downwards, completely protecting the circular saw blade within the cavities of its fixed and movable covers, thereby reducing the safety risk of accidental injury from the circular saw blade.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

The drive motor of the drive component 233 is started to drive the traveling gear 2331 to rotate on the rack 2311 and drive the U-shaped bracket of the hanging traveling wheel 232 to move longitudinally. At this time, the hanging traveling wheel 232 moves the circular cutter 21 to the preset steel pipe cutting position and then stops and brakes. Start the circular saw 21, then use the linear module 13 to drive several sets of clamping components 11 to move several steel pipes 900 laterally, so that the exposed lower half of the circular saw blade 212 of the circular saw 21 cuts the steel pipes 900. After cutting, turn off the circular saw 21, then use the linear module 13 to drive the steel pipes 900 to move laterally backward, and then move the circular saw 21 to the next preset cutting position of the steel pipe for length setting, and then cut the next part of the steel pipes 900. When the circular saw 21 is not working, the rotary cylinder 224 can be used to drive the movable cover 222 to rotate downward, so that the circular saw blade 212 is completely protected by the protective cover 22 in the cavity of its fixed cover 221 and movable cover 222.

[0038] This invention improves the steel pipe cutting device by providing a clamping assembly 1 on one side of the cutting assembly 2.

The invention utilizes the several sets of clamping components 11 to simultaneously clamp multiple steel pipes 900 and move them laterally, and the movable cover 222 of the cutting assembly 2 can be used to... The upper rotating body is retracted into the cavity of the upper fixed cover 221, exposing the lower half of the circular saw blade 212 to cut several steel pipes 900. After the circular cutting machine 21 is driven to move longitudinally to a fixed length by the lifting frame 23, it can cut the next part of several steel pipes 900, thereby achieving efficient cutting without having to release the clamping assembly 11 midway. In the non-working state, the movable cover 222 rotates downward, so that the circular saw blade 212 is completely protected by the protective cover 22 in the cavity of its fixed cover 221 and movable cover 222, thereby reducing the safety risk of the circular saw blade 212 accidentally injuring people.
