Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, specifically to a multi-purpose adjustable rectangular tube cutting device. Background Technology

[0002] Rectangular tubes are hollow, square-section, lightweight, thin-walled rectangular tubes, also known as cold-formed steel profiles. They are made from Q235 hot-rolled or cold-rolled strip steel or coils, cold-bent into shape, and then high-frequency welded to form a square cross-section. Due to their unique structural characteristics, rectangular tubes are widely used in manufacturing various mechanical parts and constructing engineering structures.

[0003] Due to varying engineering structures, different sizes of bent or straight pipes may be required for cutting. When simultaneously cutting bent (right-angled) or straight (long strip) rectangular pipes of different sizes, the common practice is to equip multiple sets of cutting equipment and assign multiple people to coordinate the cutting operation. Furthermore, cutting positioning largely relies on measuring tapes. This method is inefficient and lacks precise dimensional positioning, often resulting in unsuitable and scrapped rectangular pipes. Simultaneously, the significant vibrations generated by the cutting equipment during the cutting process negatively impact cutting accuracy, causing unevenness and deviations in the cut surface, and also pose substantial safety risks. Moreover, frequently changing cutting equipment to accommodate different sized rectangular pipes is not only time-consuming and labor-intensive but also causes significant wear and tear on the equipment, further increasing maintenance costs.

[0004] Therefore, it is very important to design an adjustable rectangular tube cutting device. Utility Model Content

[0015] The working principle and advantages of this utility model are as follows: When the workpiece is a straight (long strip) rectangular tube, one end of the workpiece can be directly positioned by the main positioning component and the second movable positioning block on the first worktable. Then, the position of the first movable positioning block is adjusted to position the other end of the workpiece, ensuring that it is not prone to positional displacement during the cutting process. When the workpiece is a bent (right-angled) rectangular tube, a section of the tube is positioned by the first worktable and the second worktable respectively.

[0026] The basic implementation examples are as follows: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown: A multi-purpose adjustable rectangular tube cutting device includes a first worktable 1 and a second worktable 8.

[0027] The first workbench 1 is provided with a cutting machine 101; the cutting machine 101 is provided with a cutting groove 102 at the processing position; a main positioning block 103 and a sliding groove 104 are provided in sequence on one side of the cutting groove 102; a first movable positioning block 2 is provided on the sliding groove 104 and slidably connected thereto; a second movable positioning block 4 is provided on the opposite side of the main positioning block 103.

[0028] Specifically, the cutting groove 102 is arranged vertically along the first worktable 1, and the sliding groove 104 is arranged horizontally along the first worktable 1.

[0029] Both the main positioning block 103 and the first movable positioning block 2 are L-shaped positioning blocks. A fixed support lug 5 is also provided on the opposite side of the main positioning block 103. Both the main positioning block 103 and the fixed support lug 5 are welded to the first worktable 1. The fixed support lug 5 has a threaded hole through which an adjusting screw 6 passes. The second movable positioning block 4 is fixedly connected to one end of the adjusting screw 6 (the end closer to the main positioning block 103). The other end of the adjusting screw 6 has a hand-held knob 7 for easy manual operation. By rotating the adjusting screw 6, the distance between the second movable positioning block 4 and the main positioning block 103 can be controlled to securely position the workpiece to be processed (i.e., the rectangular tube to be cut).

[0030] The sliding groove 104 is provided with a limiting screw 3; the first movable positioning block 2 is connected to the sliding groove 104 through the limiting screw 3; the limiting screw 3 is used to fix the position of the first movable positioning block 2 on the sliding groove 104.
