[0002] During use, square tubes generally need to be cut into required lengths according to actual needs. When cutting tubes, in order to facilitate subsequent pipe connection and sealing after pipeline connection, it is necessary to ensure that the cutting surface is flat and smooth. Therefore, many high-precision large-scale square tube cutting machines have appeared on the market. Such machines can well ensure the smoothness of the cutting surface after the square tube is cut according to the characteristics of square tubes. However, such machines are often expensive, which is undoubtedly unaffordable for small or micro square tube processing companies. Therefore, in these companies, the processing of square tubes still remains in manual cutting machines. Such cutting machines include a cutting table and a cutting knife. The cutting knife is driven by a motor. After the square tube is manually fixed on the cutting table, the cutting knife is driven to cut the square tube, and then the material is pushed manually. The whole process is basically manually operated, and it is difficult to ensure the stability of the square tube during cutting. After cutting, the smoothness of the cut surface of the square tube is even more difficult to ensure. Therefore, how to improve such cutting machines to ensure the stability of square tube cutting is very important. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0022] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the present invention should be understood by people with ordinary skills in the field to which the present invention belongs. The words "first", "second" and similar words used in the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0023] The first aspect of the utility model is as follows Figure 1 and Figure 2 As shown, it includes a cutting table 10 and a positioning assembly 20, wherein the positioning assembly 20 is composed of a sliding base plate 201, a movable vertical plate 202 and a rotating pressure plate 204, and the initial fixation of the square tube 30 relies on the mutual pressing of the rotating pressure plate 204 and the sliding base plate 201.

[0024] In this embodiment, after placing the square tube 30 on the sliding base plate 201, the worker manually rotates the rotating pressing plate 204 to press it on the square tube 30, and the two press and fix the square tube 3 up and down. After the rotating pressing plate 204 presses the square tube 30, the fixing piece 208 at the lower end of the handle 207 is located just in front of the square tube 30, and the lower end of the fixing piece 208 faces inward, so the fixing piece 208 presses against the movable vertical plate 202 just in front of and behind the square tube 30 to press and fix the square tube 30 front and back, and finally the positioning of the square tube 30 is achieved by squeezing in four directions.

[0025] In this embodiment, a fixed cutting knife 102 is provided on the cutting table 10, and a pair of positioning components 20 are provided and symmetrically arranged on both sides of the cutting knife 102 on the cutting table 10. Through the positioning of the two sets of positioning components 20, the square tube 30 is fixed more stably.

[0026] In addition, the sliding base plate 201 is slidably connected to the slide groove 101 provided on the cutting table 10, so the positioning assembly 20 can slide forward along the slide groove 101 to feed the material, making it more convenient for workers to push the material.

[0027] Preferably, rubber cushions may be provided at the positions where the rotating pressing plate 204 and the fixing member 208 for squeezing and fixing the square tube 30 contact the square tube 30 .

[0028] On the other hand, Figure 4 As shown, the movable upright plate 202 is movably connected to the sliding base plate 201 in a telescopic manner by connecting the telescopic plate 203. Therefore, it means that the distance between the movable upright plate 202 and the sliding base plate 201 is adjustable, so that the square tubes 30 of different widths can be adapted.

[0029] In the present embodiment, the handle 207 is also connected to the outer end surface of the rotating pressure plate 204 by the connecting rod 206 so as to be slidable forward and backward. Therefore, it means that the distance between the fixing member 208 and the movable vertical plate 202 is adjustable, so that the square tubes 30 of different heights can be adapted. That is, the positioning assembly 20 in the present solution can be adapted to square tubes of different specifications.

[0030] Preferably, a spring may be connected between the movable vertical plate 202 and the connecting telescopic plate 203 .

[0031] Embodiment: When a worker uses it, he only needs to place the square tube 30 on the sliding base plate 201, and then rotate the rotating pressing plate 204 to press it on the square tube 30, and at the same time hold the handle 207 with his hand and push it forward with force. Pushing the handle 207 forward not only makes the fixing part 208 press and fix the square tube 30, but also starts pushing the material directly. Finally, the square tube 30 starts cutting after contacting the cutting knife 102, and can be pulled back after cutting is completed.

[0032] Based on the above, the utility model designs a rotating pressing plate that cooperates with the sliding base plate, which can press and fix the square tube up and down through the handle, and easily achieve positioning. A retractable fixing piece is set under the handle, which can not only cooperate with the movable vertical plate to press and fix the square tube forward and backward, but also adapt to square tubes of different specifications. And the movable vertical plate can be extended and shortened, so it is suitable for square tubes of different specifications. The positioning component slides through the slide groove and cooperates with the fixed cutting props, which makes it convenient for workers to push the material when cutting.
