[0017] The present invention provides a metal square tube cutting machine with protective facilities. It has the following beneficial effects:

[0018] 1. The metal square tube cutting machine with protective facilities is to steadily cling the square tube to the horizontal end of the clamping plate, and then use the cutting device to cut the square tube, wherein the moving block in the cutting device can slide on the slide bar to achieve the effect of cutting and forming the square tube of a predetermined length.

[0019] 2. When the metal square tube cutting machine with protective facilities cuts into the hollow part of the square tube through the cutting saw, the pressure plate will squeeze the two ends of the square tube to achieve the pre-tightening effect on the two ends of the square tube.

[0020] 3.

[0022] 5. The metal square tube cutting machine with protective facilities makes the square tube touch the one-way plate, causing the one-way plate to rotate counterclockwise and stretch the laminate, so that the square tube can pass through. However, when the square tube completely enters the clamping device, the square tube will squeeze the one-way plate in the reverse direction.

DETAILED DESCRIPTION

[0034] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0035] like Figure 1-Figure 8 As shown, the present invention provides a technical solution: a metal square tube cutting machine with protective facilities, comprising a base 1, a placing device 2, a column beam device 3 and a cutting device 4, wherein the placing device 2 is arranged on the top of the base 1, the column beam device 3 is arranged on the top of the base 1, and the column beam device 3 is slidably connected with the cutting device 4;

[0036] The placing device 2 comprises a fastening plate 21, the bottom of the fastening plate 21 is fixedly connected to the top of the base 1, the top of the fastening plate 21 is fixedly connected to a placing platform 22, and the top of the placing platform 22 is fixedly connected to a clamping plate 23;

[0037] The column-beam device 3 comprises a column-beam 31, the bottom of which is fixedly connected to the top of the base 1, a slide rail 32 is provided on the surface of the column-beam 31, a clamping device 33 is provided on the surface of the column-beam 31, a support seat 35 is fixedly connected to the surface of the column-beam 31, a reinforcer 34 is provided on the surface of the support seat 35, and the reinforcer 34 is fixedly connected to the column-beam 31;

[0038] The cutting device 4 includes a pressing plate device 41, both sides of which are fixedly connected with connecting pipes 42, the surface of which is fixedly connected with a drainage groove tube 43, a sliding rod 45 is arranged inside the pressing plate device 41, a moving block 46 is slidably connected with the surface of the sliding rod 45, a cutting saw 47 is arranged at the bottom of the moving block 46, a suction device 48 is fixedly connected to the side of the moving block 46 close to the sliding rod 45, both ends of the moving block 46 are fixedly connected with connecting rods 44, and one end of the connecting rod 44 away from the moving block 46 is fixedly connected to the pressing plate device 41. The square tube is stably pressed against the horizontal end of the clamping plate 23, and then the cutting device 4 is used to cut the square tube, wherein the moving block 46 in the cutting device 4 can slide on the sliding rod 45.

[0039] When the cutting saw 47 cuts into the hollow part of the square tube, the pressing plate 411 will squeeze the two ends of the square tube.

[0040] The cutting of the square tube is completed by the cutting saw 47 , and the pressing plate 411 quickly moves the square tube cut into two pieces along the bevel of the clamping plate 23 and the drainage groove tube 43 .

[0041] The clamping device 33 includes a stopper 331, the surface of which is fixedly connected to the column beam 31, a rotating shaft 333 is provided on the surface of the column beam 31, an inner clamping plate 332 is rotatably connected to the surface of the rotating shaft 333, an outer clamping device 334 is provided on the side of the inner clamping plate 332 away from the stopper 331, and the bottom of the outer clamping device 334 is fixedly connected to the column beam 31. When the surface of the square tube touches the inner end of the inner clamping plate 332 and contacts the stopper 331, the inner clamping plate 332 will rotate counterclockwise with the rotating shaft 333 as the center, so that the other end of the inner clamping plate 332 will squeeze the square tube.

[0042] The outer clamping device 334 includes a fixed curved plate 3341, which is fixedly connected to the column beam 31. The upper surface of the fixed curved plate 3341 is rotatably connected to a one-way plate 3342. The surface of the one-way plate 3342 is fixedly connected to a laminate 3343. The end of the laminate 3343 away from the one-way plate 3342 is fixedly connected to the fixed curved plate 3341. When the square tube touches the one-way plate 3342, the one-way plate 3342 rotates counterclockwise and stretches the laminate 3343, so that the square tube can pass through. However, when the square tube completely enters the clamping device 33, the square tube will reversely squeeze the one-way plate 3342, and the laminate 3343 will fold to prevent the square tube from rolling outward.

[0043] The pressure plate device 41 includes a pressure plate 411, the slide bar 45 is arranged inside the pressure plate 411, the pressure plate 411 is fixedly connected to the connecting rod 44, the pressure plate 411 is fixedly connected to the side away from the connecting rod 44 with an inner block 415, the end of the inner block 415 away from the pressure plate 411 is fixedly connected to the inner abutment plate 412, the surface of the inner abutment plate 412 is fixedly connected to a spring 414, the end of the spring 414 away from the inner abutment plate 412 is fixedly connected to an outer abutment plate 413, and the top end of the outer abutment plate 413 is rotatably connected to the inner abutment plate 412. The compression of the square tube by the outer abutment plate 413 causes the spring 414 fixed on the other side of the outer abutment plate 413 to be compressed, so that the outer abutment plate 413 rotates clockwise on the inner abutment plate 412.

[0044] The suction device 48 includes a suction pipe 481, one end of which is fixedly connected to the moving block 46, and a ring shaft 483 is provided inside the suction pipe 481. An inner metal sheet 482 is rotatably connected to the surface of the ring shaft 483, and an outer metal sheet 484 is fixedly connected to the surface of the inner metal sheet 482. Since the deformation of the outer metal sheet 484 is greater than that of the inner metal sheet 482, the outer metal sheet 484 will be bent toward the inside of the suction pipe 481 due to the heat and drive the inner metal sheet 482.

[0045] When in use, the square tube is placed on the placement table 22, and then the square tube is stably pressed against the horizontal end of the clamping plate 23. Then the cutting device 4 is used to cut the square tube, wherein the moving block 46 in the cutting device 4 can slide on the slide rod 45 to achieve the effect of cutting and forming the square tube of a predetermined length.

[0046] The movable block 46 is connected to the pressure plate 411 through the connecting rod 44, and the bottom of the movable block 46 is fixedly connected with a cutting saw 47. Therefore, when the cutting saw 47 cuts the square rectangular tube, the pressure plate 411 will also squeeze the two ends of the square rectangular tube. The cutting saw 47 cuts the square rectangular tube first, and the clamping plate 23 fixes the square rectangular tube. When the cutting saw 47 cuts into the hollow part of the square rectangular tube, the pressure plate 411 will squeeze the two ends of the square rectangular tube to achieve a pre-tightening effect on the two ends of the square rectangular tube.

[0047] When the cutting saw 47 cuts the last bit of thickness of the square tube, the square tube will suddenly vibrate. At this time, the pressure plate 411 and the cutting saw 47 will apply force to the square tube at the same time. At the same time, the cutting saw 47 completes the cutting of the square tube, and the pressure plate 411 quickly moves the square tube cut into two pieces along the bevel of the clamping plate 23 and the drainage groove tube 43 to prevent the shaking of the square tube from affecting the flatness of the port cutting.

[0048] The square tube cut into two ends will continue to be squeezed by the pressure plate 411 and move along the hypotenuse of the clamping plate 23 and the drainage groove tube 43, and finally enter the clamping device 33. When the surface of the square tube touches the inner end of the inner clamp 332 and conflicts with the block 331, the inner clamp 332 will rotate counterclockwise with the rotating shaft 333 as the center, so that the other end of the inner clamp 332 will squeeze the square tube to achieve the fixing effect of the square tube, wherein the left half of the inner clamp 332 is closer to the square tube than the right half.

[0049] The square tube touches the one-way plate 3342, causing the one-way plate 3342 to rotate counterclockwise and stretch the laminate 3343, allowing the square tube to pass through. However, when the square tube completely enters the clamping device 33, the square tube will squeeze the one-way plate 3342 in the reverse direction. At this time, the laminate 3343 will fold to prevent the square tube from rolling outward, thereby fixing the square tube.

[0050] The outer abutment plate 413 squeezes the other rectangular tube, so that the spring 414 fixed on the other side of the outer abutment plate 413 is squeezed, so the outer abutment plate 413 rotates clockwise on the inner abutment plate 412 to relieve the pressure on the other rectangular tube.

[0051] When the cutting saw 47 cuts the rectangular tube, a large amount of high-temperature iron filings will splash out and spray onto the bimetallic strip. Because the deformation of the outer metal sheet 484 is greater than that of the inner metal sheet 482, the outer metal sheet 484 will be heated and drive the inner metal sheet 482 to bend toward the inside of the suction pipe 481, so as to achieve the purpose of collecting and processing the iron filings by the suction force inside the suction pipe 481.

[0052] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
