[0002] A structure is a structure composed of steel materials and is one of the main building structure types. For example, steel structures such as angle steel, H-shaped steel or square pipes. During the production of steel structures, a cutting machine is generally used to cut the steel structure into a specific length to facilitate the use and sale of the steel structure.

[0003] When the existing cutting machine cuts a square pipe, generally, the square pipe is fixed on the operating table by a fixture, and then the cutting wheel is used to cut the square pipe. During the process of the cutting wheel rubbing against the square pipe, a large contact force will be generated between the cutting wheel and the square pipe. And for some square pipes with thin pipe walls, it may cause the deformation of the pipe wall near the cutting part of the square pipe, and subsequent leveling treatment by the operator is required, reducing the cutting efficiency of the square pipe steel structure.

[0020] In order to make the technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0021] The present utility model provides a technical solution: Refer to Figures 1-4 , a steel structure cutting machine disclosed by the present utility model includes a loading platform 1 and a cutting mechanism 2. A rectangular hole 5 is opened at one end of the top side of the loading platform 1. The cutting mechanism 2 is fixedly installed on the bottom side of the loading platform 1 through bolts, and the top of the cutting wheel of the cutting mechanism 2 penetrates through the rectangular hole 5. An adjusting mechanism 3 is fixedly installed on the loading platform 1, and a support mechanism 4 is arranged on the outer periphery of the adjusting mechanism 3.

[0022] In this embodiment, when the improved steel structure cutting machine is in use, the operator sleeves the square pipe on the adjusting mechanism 3, locks the position of the square pipe on the loading platform 1 through the support mechanism 4, and at the same time makes the cutting wheel of the cutting mechanism 2 align with a specific position on the square pipe. At this time, the adjusting mechanism 3 and the support mechanism 4 cooperate with each other to support and limit the pipe wall at the cutting position of the square pipe from the inside and outside of the square pipe, so that the pipe wall of the square pipe is stably kept straight, and the feeding operation of the square pipe is completed;

[0023] After the square pipe is loaded, the adjusting mechanism 3 drives the square pipe to rotate rapidly, and at the same time the cutting mechanism 2 slowly pushes the rotating cutting wheel towards the square pipe, so as to cut off the pipe wall of the square pipe. When the square pipe rotates, the gas on the outer peripheral side of the square pipe flows rapidly, so that the heat on the square pipe can be quickly carried away by the air flow, and the square pipe is quickly cooled.

[0024] In a further preferred embodiment of the present utility model, as Figure 1 and Figure 2 shown, the adjusting mechanism 3 includes a base 31. The base 31 is fixedly installed on the other end of the top side of the loading platform 1 through bolts. A scale rod 32 is arranged on one side of the base 31, and one end of the scale rod 32 is inserted into the base 31 and rotatably connected to the base 31 through a bearing;

[0025] In this embodiment, when the above-mentioned feeding process of the square pipe is carried out, the operator sleeved the square pipe on the scale rod 32, and can quickly determine the length of the square pipe after cutting according to the scale on the square pipe, which facilitates the feeding process of the square pipe.

[0026] In a further preferred embodiment of the present utility model, as Figure 2 shown, a baffle 33 is slidably sleeved on the outer peripheral side of the scale rod 32. A knob 34 is provided on the front side of the baffle 33, and the rear end of the knob 34 is inserted into the baffle 33 and contacts the outer peripheral wall of the scale rod 32. The knob 34 is threadedly connected to the baffle 33;

[0027] In this embodiment, the operator reversely rotates the knob 34 to separate the knob 34 from the scale rod 32. Then, according to the length of the steel structure to be cut and the scale on the scale rod 32, the baffle 33 is pushed to move the baffle 33 to a suitable position on the scale rod 32. Then, the knob 34 is rotated forward to make the knob 34 contact the scale rod 32, so as to lock the position between the baffle 33 and the scale rod 32 by the frictional force generated when the knob 34 contacts the scale rod 32;

[0028] During the process of the above square tube being sleeved on the scale rod 32, it is possible to directly determine whether the square tube is installed in place by the mutual contact between the end of the square tube and the baffle 33, without the need for the operator to manually adjust, which facilitates the feeding process of the square tube.

[0029] In a further preferred embodiment of the present utility model, as Figure 1 and Figure 2 shown, a motor 35 is fixedly installed on the other side of the base 31, and the driving end of the motor 35 is inserted into the base 31 and fixedly connected to the scale rod 32. Two support blocks 36 are fixedly sleeved on the outer peripheral side of the other end of the scale rod 32, and the two support blocks 36 are relatively arranged on both sides of the rectangular hole 5. The baffle 33 is located between the base 31 and the corresponding support block 36;

[0030] In this embodiment, after the above square tube is installed, the motor 35 drives the scale rod 32 to drive the support block 36 to slowly rotate. Due to the mutual contact between the support block 36 and the inner wall of the square tube, the square tube synchronously rotates rapidly with the scale rod 32, so as to adjust the contact position between the square tube and the cutting wheel by the rotation of the square tube, so that the rotating cutting wheel does not rub against the same position of the square tube for a long time, resulting in too high temperature at this position of the square tube.

[0031] In a further preferred embodiment of the present utility model, as Figure 1 , Figure 3 and Figure 4 shown, the support mechanism 4 includes two support plates 41. The support plates 41 are sleeved on the outer peripheral side of the corresponding support blocks 36, and the support plates 41 are fixedly connected to the carrier table 1 by bolts. A circular plate 42 is rotatably penetrated through the support plates 41 through bearings. A square hole 43 is opened at the center position of the circular plate 42, and the support block 36 penetrates through the corresponding square hole 43. The support block 36 is in clearance fit with the inner wall of the corresponding square hole 43;

[0032] In this embodiment, during the rotation of the square tube, the square tube can be supported and limited by the support plate 41 and the circular plate 42, so as to avoid the position deviation of the square tube caused by the mutual contact between the square tube and the cutting wheel;

[0033] During the cutting of the square tube, due to the mutual contact between the inner wall of the square tube and the support block 36 and the mutual contact between the outer wall of the square tube and the inner wall of the square hole 43 of the circular plate 42, the tube wall near the cutting position of the square tube is stably kept flat.

[0034] In a further preferred embodiment of the present utility model, as Figure 3 and Figure 4 shown, the opening corners at both ends of the square hole 43 are both arranged in an arc shape. Counterweight blocks 44 are fixedly installed on the reverse sides of the two circular plates 42, and the counterweight blocks 44 are located below the corresponding square holes 43. A threaded rod 45 is installed through the counterweight blocks 44 in a threaded manner;

[0035] In this embodiment, the arc-shaped setting of the opening end of the square hole 43 can expand the area of the opening end of the square hole 43, making it easier for the square tube to pass through the square hole 43. The setting of the counterweight blocks 44 can change the center of gravity position of the circular plate 42, so that the circular plate 42 always maintains a specific state without external force, facilitating the installation of the square tube;

[0036] After the above-mentioned square tube is installed, the operator rotates the threaded rod 45, and locks the position between the square tube and the circular plate 42 through the frictional force generated when the threaded rod 45 contacts the square tube.

[0037] Working principle: When the improved steel structure cutting machine is used, first, the operator reversely turns the knob 34 to separate the knob 34 from the scale rod 32. Then, according to the length of the steel structure to be cut and the scale on the scale rod 32, the baffle 33 is pushed so that the baffle 33 moves to a suitable position on the scale rod 32. Then, the knob 34 is turned forward so that the knob 34 contacts the scale rod 32, and thus the position between the baffle 33 and the scale rod 32 is locked through the frictional force generated when the knob 34 contacts the scale rod 32;

[0038] After the position of the above-mentioned baffle 33 is adjusted, the operator sleeves the square tube on the support block 36. At this time, due to the mutual contact between the support block 36 and the inner wall of the square tube, the square tube moves along a horizontal linear trajectory, so that the square tube directly passes through the square hole 43 and is sleeved on the scale rod 32 until the end of the square tube contacts the baffle 33. At this time, the cutting wheel of the cutting mechanism 2 is located at a specific position on the square tube. Finally, the threaded rod 45 is rotated forward to lock the position of the square tube through the mutual contact between the threaded rod 45 and the square tube;

[0039] After the installation of the above square tube is completed, the motor 35 drives the scale rod 32 to drive the support block 36 to rotate slowly. Due to the mutual contact between the support block 36 and the inner wall of the square tube, the square tube synchronously rotates rapidly with the scale rod 32. At the same time, the cutting mechanism 2 starts to slowly push the cutting wheel towards the square tube, thus completing the cutting process of the square tube wall;

[0040] It should be noted that during the cutting process of the square tube wall, due to the mutual contact between the inner wall of the square tube and the support block 36 and the mutual contact between the outer wall of the square tube and the circular plate 42, the wall of the square tube is stably kept straight;

[0041] During the rotation of the above square tube, the air flow on the outer periphery of the square tube flows rapidly, thus quickly taking away the heat on the square tube and preventing the square tube from overheating;

[0042] After the square tube is cut, the operator reversely turns the threaded rod 45 to release the restraint positioning of the square tube. At this time, the operator can directly pull out the uncut square tube and the square tube of a specific length after cutting from the scale rod 32. At the same time, due to the action of the counterweight 44, the circular plate 42 automatically rotates and resets to facilitate the subsequent installation of the square tube. According to the above repeated operations, the cutting process of the square tube can be continuously carried out.

[0043] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
