Description

Technical Field

[0001] This utility model relates to the field of cutting, specifically a continuous cutting device for square and rectangular tubes. Background Technology

[0002] Square and rectangular tubes are a type of steel pipe, referring to steel pipes with equal or unequal side lengths. They are made from strip steel through a processing technique. Generally, the strip steel is unpacked, flattened, rolled, and welded into a round tube, which is then rolled into a square tube. Square and rectangular tubes are widely used in the metal pipe processing industry. In actual production, it is often necessary to cut square and rectangular tubes into pipes of specific lengths.

[0003] Currently, most existing square and rectangular tube cutting methods rely on manual operation of cutting equipment. When cutting large batches of square and rectangular tubes of the same length, it is inconvenient to quickly position the cutting length of the tubes, resulting in low cutting efficiency, high labor intensity, and difficulty in guaranteeing cutting accuracy. Therefore, a continuous square and rectangular tube cutting device is proposed to address these issues. Utility Model Content

[0025] Please see Figures 1-4As shown, a continuous cutting device for square and rectangular tubes includes a worktable 1. Support columns 2 are fixedly installed at the four corners of the lower part of the worktable 1. A cutting machine body 18 for cutting square and rectangular tubes is installed on the upper part of the worktable 1. A mounting hole 3 is opened on one side of the cutting machine body 18 on the worktable 1. The mounting hole 3 is rectangular. A slide table 5 is slidably installed in the mounting hole 3. A first limiting plate 11 and a second limiting plate 12 are fixedly installed on the upper surface of the slide table 5. The first limiting plate 11 and the second limiting plate 12 are arranged in an L-shape on the slide table 5. A pressure plate 16 is installed above the slide table 5 and can be raised and lowered. A positioning plate 21 is slidably installed at the corner on the other side of the worktable 1.

[0026] Through the design of the slide table 5, the first limiting plate 11, the second limiting plate 12, the pressure plate 16, and the positioning plate 21, the distance between the slide table 5 and the cutting machine body 18 can be adjusted according to the required length of the rectangular tube to be cut, thereby achieving the purpose of controlling the cutting length of the rectangular tube. The L-shaped design of the first limiting plate 11 and the second limiting plate 12 allows the first limiting plate 11 to limit one end of the rectangular tube after it is placed on the worktable 1, which facilitates the control of the cutting length. The second limiting plate 12 can position one side of the rectangular tube. During cutting, the pressure plate 16 can press on the rectangular tube, which facilitates the sequential pushing of the rectangular tube for positioning and cutting, improving the stability during cutting. The positioning plate 21 facilitates the quick alignment of the rectangular tube, improving the processing accuracy.

[0027] Among them, the mounting hole 3 has a sliding groove 4 on both sides opposite to each other, and a slider 6 is slidably installed in each of the two sliding grooves 4. One side surface of the two sliders 6 is fixedly connected to the opposite sides of the slide table 5.

[0028] To ensure the slide table 5 is slidable, two sliders 6 installed in the slide groove 4 are fixedly connected to the slide table 5, so that the slide table 5 can slide linearly within the mounting hole 3.

[0029] Among them, the upper part of the slide table 5 is fixedly installed with a support plate 13 on one side of the second limiting plate 12, and a horizontal plate 14 is fixedly connected to the upper end of the support plate 13, and the pressure plate 16 is located at the bottom of the horizontal plate 14.

[0030] In order to enable the pressure plate 16 to be raised and lowered above the slide table 5, a horizontal plate 14 is installed on the support plate 13 to facilitate the lifting and lowering of the pressure plate 16 on the slide table 5.

[0031] Among them, a cylinder 15 is fixedly installed on the upper part of the horizontal plate 14, one end of the piston rod of the cylinder 15 is fixedly connected to the upper surface of the pressure plate 16, and a rubber pad 17 is provided on the lower surface of the pressure plate 16.

[0032] In order to achieve the lifting and lowering of the pressure plate 16, the piston rod of the cylinder 15 installed on the horizontal plate 14 can extend and retract, which can control the up and down movement of the pressure plate 16, thereby facilitating the positioning of the rectangular tube.

[0033] Among them, a movable block 7 is fixedly installed on the lower surface of the slide table 5, and a screw 9 is threaded through the movable block 7.

[0034] To facilitate the sliding of the slide table 5, the first screw 9 of the drive mechanism rotates, and the moving block 7 moves linearly on the first screw 9 under the engagement of the thread, thereby driving the slide table 5 to slide, which facilitates the control of the sliding of the slide table 5.

[0035] Among them, both ends of the No. 1 screw 9 are rotatably mounted with mounting plates 8, and both mounting plates 8 are fixedly connected to the lower surface of the workbench 1.

[0036] To ensure the rotation of the first screw 9 by sliding the slide table 5, two mounting plates 8 are used to rotate and install it under the worktable 1, making it convenient to drive the first screw 9 to rotate.

[0037] Among them, a motor 10 for driving the first screw 9 is fixedly installed on the lower part of the workbench 1 away from the positioning plate 21.

[0038] To facilitate the rotation of the No. 1 screw 9, the motor 10 is set to control its forward and reverse rotation, which allows for easy adjustment of the distance between the motor and the cutting machine body 18 as needed, saving time and effort and improving processing efficiency.

[0039] Among them, a second screw 20 is rotatably connected to one side surface of the positioning plate 21, and a side plate 19 is threaded through the second screw 20. The side plate 19 is fixedly installed on the upper surface of the workbench 1, and a rocker plate 22 is installed at the other end of the second screw 20.

[0040] To facilitate the positioning of the movable positioning plate 21, a rocker plate 22 is provided to drive the second screw 20 to rotate. With the help of the thread, the second screw 20 will step inward to the side plate 19, thus facilitating the positioning of the movable positioning plate 21.

[0041] Working principle: Through the design of the slide table 5, the first limiting plate 11, the second limiting plate 12, the pressure plate 16, and the positioning plate 21, the distance between the slide table 5 and the cutting machine body 18 is adjusted according to the required length of the rectangular tube to be cut, thereby achieving the purpose of controlling the cutting length of the rectangular tube. The L-shaped design of the first limiting plate 11 and the second limiting plate 12 allows the first limiting plate 11 to limit one end of the rectangular tube after it is placed on the worktable 1, which facilitates the control of the cutting length. The second limiting plate 12 can position one side of the rectangular tube. During cutting, the pressure plate 16 can press on the rectangular tube to improve the stability during cutting. The positioning plate 21 facilitates the quick alignment of the rectangular tube and improves the processing accuracy.
