[0001] The utility model relates to the technical field of steel pipe furniture processing, in particular to a fixed-length cutting device for steel pipe furniture. Background Art

[0002] Steel pipe furniture is made of steel pipe as the main raw material. Common beds, chairs, tables, etc. are all made of steel pipes. When processing steel pipe furniture, the steel pipe needs to be cut.

[0003] For example, the Chinese utility model patent with the authorization announcement number CN220278408U relates to a steel pipe cutting device, which belongs to the field of pipe cutting machines and includes a support, on which a cutting assembly for cutting steel pipes and a roller assembly for positioning steel pipes are arranged. The roller assembly includes a roller seat symmetrically arranged on the support, which is slidably connected to the support, and the roller seats are connected by a double-rotation screw thread. The roller seat is installed with a first roller and a second roller configured as a U-shaped structure for contacting the steel pipe for rotation. The rotating shaft of the first roller can slide along the plumb direction of the roller seat, and the two ends of the rotating shaft are slidably connected to the inclined groove on the base; the screw drives the roller seat to drive the second roller to move closer, so that the rotating shaft of the first roller can slide downward along the inclined groove, so that the first roller moves downward to contact the side wall of the steel pipe. The roller used to position the pipe body can be adjusted. When a smaller pipe body is replaced for cutting, the position of the roller is adjusted to contact the pipe body to avoid falling off when cutting a smaller pipe body.

[0004] The above-mentioned authorized patent has the following problems during use:

[0005] It is impossible to cut the steel pipe to a fixed length. When cutting the steel pipe to a fixed length, it is necessary to measure the length of the steel pipe with a ruler and mark it before cutting it, which leads to slow cutting efficiency. In addition, only one side of the steel pipe is fixed, which makes the steel pipe shake easily during cutting, which easily leads to uneven cutting surface.

[0006] In view of the above problems, it is urgently necessary to carry out innovative design based on the original steel pipe cutting device for steel pipe furniture. Utility Model Content

An indicator plate 210 is fixed to the rear side of the outer rod 206, and the inner side of the indicator plate 210 is aligned with the support rod 2 01 are fitted together, a scale line 209 is set on the support rod 201, the outer rod 206 is located between the support rods 201, the threaded rod 207 and the nut 208 are threadedly connected, the inner rod 205 and the through groove 203 constitute a sliding structure, and the outer wall of the outer rod 206 is fitted together with the outer wall of the support rod 201, ensuring that the outer rod 206 and the indicator plate 210 can move left or right under the action of the guide groove 202, the through groove 203, the guide block 204 and the inner rod 205, so that the position of the outer rod 206 and the indicator plate 210 can be adjusted, so that the scale value indicated on the right side of the indicator plate 210 on the scale line 209 can be changed, so that the length of the steel pipe to be cut can be quickly determined, thereby improving work efficiency.

[0029] The cutting mechanism 3 includes a first L-shaped fixing frame 301, which is fixed to the rear side of the top center of the desktop 1, a cylinder 302 is fixed through the top of the first L-shaped fixing frame 301, a hood 303 is fixed to the lower end of the cylinder 302, a motor 304 is fixed inside the hood 303, a cutting disc 305 is fixed to the output end of the motor 304 through the side wall of the hood 303, and a knife groove 306 is provided at the top of the desktop 1 below the cutting disc 305.

[0030] The fixing mechanism 4 includes a second L-shaped fixing frame 401. The top of the desktop 1 is located on both sides of the cylinder 302, and the second L-shaped fixing frame 401 is fixed. The top of the second L-shaped fixing frame 401 is penetrated by a rotating shaft 402. The lower end of the rotating shaft 402 is rotatably mounted with a pressing plate 403 through a bearing.

[0033] Working principle: When using the fixed-length cutting device for steel pipe furniture, first determine the position of the outer rod 206 according to the length of the steel pipe to be cut, then rotate the nut 208. Since the nut 208 and the threaded rod 207 are threadedly connected, the nut 208 moves upward, then move the outer rod 206 to the left or right, and then the outer rod 206 drives the guide block 204 to move inside the guide groove 202 through the inner rod 205. The outer rod 206 drives the indicator plate 210 to move at the same time until the scale value indicated on the scale line 209 on the right side of the indicator plate 210 is the same as the length of the steel pipe to be cut, and then rotate the nut 208 so that the bottom of the nut 208 fits tightly with the top of the outer rod 206, and the outer rod 206 and the indicator plate 210 are fixed;

[0034] Next, place the steel pipe between the two support rods 201, then make the left end of the steel pipe contact with the right side of the outer rod 206, then rotate the handle 404 on the left, and then the handle 404 drives the rotating shaft 402 to rotate. Since the second L-shaped fixing frame 401 and the rotating shaft 402 are threadedly connected, and the guide rod 405 and the second L-shaped fixing frame 401 form a sliding structure, the rotating shaft 402 pushes the pressing plate 403 and the guide rod 405 to move downward, and cooperate with the two support rods 201 on the left to complete the left side fixation of the steel pipe cutting place, and then rotate the handle 404 on the right to make the pressing plate 403 on the right move downward, and cooperate with the two support rods 201 on the right to complete the right side fixation of the steel pipe cutting place;

[0035] Then the motor 304 is started, and then the motor 304 drives the cutting disc 305 to rotate, and then the cylinder 302 is started, and then the cylinder 302 drives the rotating cutting disc 305 to move downward, thereby completing the cutting of the steel pipe;

[0036] Then take down the cut steel pipe, and then fit the left end of the remaining steel pipe to the right side of the outer rod 206, and then continue to cut the steel pipe according to the above operation, so as to achieve fast fixed-length cutting of the steel pipe.

[0037] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein.
