DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-Figure 3, a cutting device for square tubes, comprising a placing table 1, a supporting plate 2 is fixedly connected to the top of the placing table 1, a motor 3 is fixedly connected to the outer wall of the supporting plate 2, an irregular gear 5 is fixedly connected to the driving end of the motor 3, a sliding groove is provided on the top of the placing table 1, a sliding plate 8 is slidably inserted in the sliding groove, a cutting machine 9 is fixedly connected to the right wall of the sliding plate 8, a detachable cutting blade 10 is fixedly installed on the driving end of the cutting machine 9, a reset spring 7 is fixedly connected to the inner wall of the sliding groove, the end of the reset spring 7 is fixedly connected to the outer wall of the sliding plate 8, an extension plate 6 is fixedly connected to the left side of the sliding plate 8, a plurality of convex teeth 4 are fixedly connected to the top of the extension plate 6, the irregular gear 5 is meshed with the convex teeth 4, a groove is provided on the top of the placing table 1 on the right side of the sliding groove, an inclined plate 11 is fixedly connected to the inner wall of the groove, when the square tube falls to the inclined plate 11, the square tube will slide to the bottom of the inclined plate 11 due to gravity, which is convenient for personnel to take it together, the supporting plate 2 is located on the leftmost side of the placing table 1, the groove and the inclined plate 11 are located at the cutting Directly below the cutting blade 10, when it is necessary to cut the square tube, the irregular gear 5 is rotated by the motor 3, and the irregular gear 5 drives the sliding plate 8 to perform intermittent motion through the convex teeth 4 and the extension plate 6. When the regular surface of the irregular gear 5 contacts the convex teeth 4, the sliding plate 8 moves vertically backward along the sliding groove. At this time, the reset spring 7 is pre-stressed, and the sliding plate 8 will drive the cutter 9 to move when it moves backward. During the movement, the cutting blade 10 is rotated by the cutter 9. When the cutting blade 10 moves to contact the square tube, the cutting action begins. When the reset spring 7 is pre-stressed to the limit, the cutting work is completed. At this time, the square tube cut down will fall into the groove and be placed on the inclined plate 11. When the reset spring 7 is pre-stressed to the limit, the irregular surface of the irregular gear 5 will face the top of the convex teeth 4. At this time, the reset spring 7 is stretched and drives the sliding plate 8 to move to the initial state, thereby completing the reciprocating intermittent motion, and the square tube can be continuously cut without the need for personnel to hold the cutting machine 9 for cutting, thereby reducing the risk of personal injury.

[0020] The top of the placement table 1 is fixedly connected with a sliding convex plate 12 located on the right side of the cutting machine 9, and the top of the sliding convex plate 12 is slidably connected with a sliding block 14, and the left side wall of the sliding block 14 is fixedly connected with a lower clamp 16, and an upper clamp 13 is arranged above the lower clamp 16, and the upper clamp 13 is threadedly connected to the lower clamp 16 by a bolt 15, and the lower clamp 16 and the cutting machine 9 are located in the same horizontal plane. When cutting is required, the square tube is first placed in the lower clamp 16, and then the upper clamp 13 is brought into contact with the square tube by rotating the bolt 15, so that the square tube is fixed by the upper clamp 13 and the lower clamp 16. When the cutting machine 9 is started, the personnel only need to put their hands on the sliding block 14, and adjust the position of the square tube to be cut by sliding the sliding block 14, which can lengthen the contact distance with the cutting surface and improve safety.
