[0042] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] Metal pipes are widely used in furniture, decoration, construction and other industries. Such pipes generally need to be processed when used, such as being cut according to different length requirements. Therefore, a cutting device is required when cutting metal pipes. Currently, cutting machines mostly fix pipes on the machine with a clamping mechanism, and then use the cutting disc to rotate at high speed to cut the pipes. Therefore, please refer to Figure 1-Figure 9 As shown, this embodiment provides a metal pipe cutting device capable of automatic feeding, comprising at least:

[0044] A placement guide assembly 100 is used to stack a plurality of metal pipes to be cut;

[0045] A material cutting guide assembly 300, which is used to guide the cutting of the metal pipe after cutting;

[0046] A limit frame 200 is provided with a stop groove 201 near the top of the placement guide assembly 100, and a cutting groove 202 is provided near the top of the unloading guide assembly 300. A rotating cutting assembly 210 for cutting metal pipe fittings is provided directly above the cutting groove 202, and an automatic feeding drive assembly 220 is provided inside the limit frame 200. The automatic feeding drive assembly 220 penetrates the stop groove 201 and the cutting groove 202 during the movement process, so that the metal pipe fittings slide from the placement guide assembly 100 into the stop groove 201 in sequence, and are pushed into the cutting groove 202 by the automatic feeding drive assembly 220. When the rotating cutting assembly 210 completes cutting the metal pipe fittings, the automatic feeding drive assembly 220 pushes the metal pipe fittings into the unloading guide assembly 300 again, wherein:

[0047] The rotary cutting assembly 210 is provided with an elastic partition assembly 230 that moves with the cutting position. The elastic partition assembly 230 is used to separate the material discharge guide assembly 300 into two spaces so that the metal pipes cut into two parts are discharged from the two spaces respectively.

[0048] like Figure 1-Figure 4As shown, the present invention takes into account that it is not convenient to automatically load materials when cutting multiple metal pipes. Workers need to constantly take metal pipes, which is labor-intensive, time-consuming and labor-intensive. Therefore, multiple metal pipes are stacked on the top of the placement guide component 100, so that one of the metal pipes slides from the top of the placement guide component 100 into the pause groove 201, and the automatic loading drive component 220 pushes the metal pipe in the pause groove 201 into the cutting groove 202, and the other metal pipe enters the pause groove 201. After the rotating cutting component 210 cuts the metal pipe into two sections in the cutting groove 202, the cut metal pipe is slid into the unloading guide component 300 by the automatic loading drive component 220 for unloading. At the same time, the automatic loading drive component 220 drives another metal pipe from the pause groove 201 to push into the cutting groove 202. The above operation is repeated, so that it is more convenient to cut multiple metal pipes for automatic loading, saving time and labor.

[0049] In addition, the current cutting machine tools are lacking in functionality. After the cutting of metal pipes is completed, it is not convenient to discharge the cut metal pipes. Although the metal pipes can be made to fall directly, they cannot be separated according to the cutting position, resulting in long pipes and short pipes being mixed together, which requires subsequent screening. Therefore, by rotating the cutting assembly 210 to change the cutting position and aligning the cutting piece with the metal pipe in the cutting groove 202 for cutting, the elastic separation assembly 230 is driven to change the two spaces separated by the feeding guide assembly 300 as the cutting position changes, so that the two cut sections of metal pipes are just aligned with the two spaces for feeding guidance, thereby avoiding mixing of pipes and improving the convenience of feeding and the screening effect.

[0050] On the basis of the above, the specific structure is disclosed in detail:

[0051] First, it is necessary to realize that the metal pipe is pushed from the pause groove 201 into the cutting groove 202 by the automatic feeding drive assembly 220 more stably. Figure 4 As shown, an inclined plate 203 is provided between the pause groove 201 and the cutting groove 202, and the inclined plate 203 is inclined from the pause groove 201 to the cutting groove 202, so that the metal pipe is first located inside the pause groove 201, and then driven by the automatic feeding drive assembly 220, the metal pipe rolls onto the inclined plate 203, and then rolls along the inclined surface of the inclined plate 203 to the inside of the cutting groove 202, thereby ensuring the stability of the metal pipe being pushed in.

[0052] Then, to realize automatic feeding, the driving assembly 220 can push the metal pipe from the pause groove 201 to the inside of the cutting groove 202, and after the cutting is completed, the cutting groove 202 is pushed into the unloading guide assembly 300 for unloading. Figure 7As shown, the structure of the automatic feeding drive assembly 220 is further disclosed, so that the automatic feeding drive assembly 220 at least includes a movable plate 221 sliding inside the limit frame 200, and a plurality of first arc push plates 222 are evenly spaced on the top of the movable plate 221. The first arc push plates 222 extend from the plurality of first grooves opened on the inner wall of the cutting groove 202 to the inside of the limit frame 200, and an extension plate 223 is connected to the end of the movable plate 221, and the extension plate 223 extends into the inside of the pause groove 201. A plurality of second arc push plates 224 are provided on the surface of the extension plate 223, and the second arc push plates 224 extend from the second grooves inside the pause groove 201 to the inside of the limit frame 200, wherein:

[0053] When the movable plate 221 slides to the top of the inner cavity of the limiting frame 200, the first arc push plate 222, the inclined plate 203 and the second arc push plate 224 are inclined toward the downward material guide assembly 300, and slide from the inside of the placement guide assembly 100 to the inside of the pause groove 201 in sequence through the metal pipe fittings, and then, the movable plate 221 slides upward inside the limiting frame 200, driving the second arc push plate 224 and the first arc push plate 222 to extend out of the limiting frame 200, and the second arc push plate 224 is supported inside the pause groove 201, lifting the metal pipe fittings to above the inclined plate 203, so that the metal pipe fittings slide along the second arc push plate 224 into the top of the inclined plate 203, and then slide to the inside of the cutting groove 202;

[0054] At the same time, the metal pipe inside the cutting groove 202 is lifted by the first arc push plate 222, so that the metal pipe slides along the surface of the first arc push plate 222 to the inside of the unloading guide assembly 300, thereby realizing the automatic loading and unloading of multiple metal pipes in sequence, thereby improving convenience;

[0055] Furthermore, during cutting, the rotary cutting assembly 210 can extend into the first groove for cutting when the metal pipe is located inside the cutting groove 202. At this time, the first arc push plate 222 is completely located inside the limiting frame 200 to ensure structural integrity.

[0056] Specifically, when the movable plate 221 slides inside the limit frame 200, in order to improve automation, it is necessary to open a groove on the inner wall of the limit frame 200, and a transmission screw 225 is rotatably provided in the groove. One end of the transmission screw 225 extends out of the limit frame 200 and is connected to the output shaft of the transmission motor 2250. The transmission screw 225 is threadedly connected to the edge of the movable plate 221. The transmission motor 2250 is powered on to make it work. The output shaft of the transmission motor 2250 drives the transmission screw 225 to rotate inside the groove, so that the movable plate 221 slides along the thread of the transmission screw 225, thereby driving the first arc push plate 222 and the second arc push plate 224 to move up and down more conveniently.

[0057] Next, in order to realize that the placement guide assembly 100 can store multiple metal pipes and allow the metal pipes to enter the interior of the pause groove 201 in sequence, it is necessary to further disclose the structure of the placement guide assembly 100, please refer to Figure 5-Figure 6 As shown, the placement guide assembly 100 at least includes a placement frame 110 connected to the outer wall of the limit frame 200, a mesh plate 120 is provided at the bottom of the inner cavity of the placement frame 110, and the mesh plate 120 is inclined toward the inside of the pause groove 201, and the inner size of the pause groove 201 is adapted to the size of a metal pipe. Through the mesh plate 120, when multiple metal pipes are stacked inside the placement frame 110, as the metal pipes roll, impurities on the surface of the metal pipes can fall downward from the gaps of the mesh plate 120, so as to achieve dust screening of the metal pipes, and as the metal pipes roll into the pause groove 201 along the inclined surface of the mesh plate 120, since the pause groove 201 can only accommodate one metal pipe, each time the second arc push plate 224 can push one metal pipe into the cutting groove 202;

[0058] Among them, since the surface of the grid plate 120 is inclined, it is easy to cause a large number of metal pipes to roll down completely. Therefore, a limiting protrusion can be set between the placement rack 110 and the pause groove 201 to prevent a large number of metal pipes from rolling down (not shown in the figure). This is common knowledge among people in this technical field and will not be elaborated here. At the same time, when the second arc push plate 224 extends from the inside of the pause groove 201, the second arc push plate 224 can be used to prevent other metal pipes inside the placement rack 110 from continuing to roll down, thereby ensuring that the metal pipes are cut in sequence.

[0059] It is worth noting that in order to realize the basic function of the rotary cutting assembly 210 to completely cut the metal pipe in the cutting groove 202 and to conveniently change the cutting position at will, please refer to Figure 8 As shown, the structure of the rotary cutting assembly 210 is further disclosed, so that the rotary cutting assembly 210 at least includes a support frame 211 sliding on the outer wall of the limit frame 200, the support frame 211 is located directly above the cutting groove 202, and a transverse frame 212 is slidably provided inside the support frame 211, and a cutting disk 213 is rotatably provided near the lower end of the transverse frame 212, and the end of the cutting disk 213 is connected to the output shaft of the cutting motor 2130, and the cutting disk 213 is adapted to the first groove, and the metal pipe is located inside the cutting groove 202, and the transverse frame 212 is slid inside the support frame 211 to change the cutting position, and the limit frame 200 slides on the outer wall of the support frame 211 to change the cutting height, driving the cutting disk 213 to contact the position to be cut, and the cutting disk 213 is driven by the output shaft of the cutting motor 2130 to rotate at a high speed to cut the metal pipe, and as the cutting slides downward, the cutting disk 213 extends into the first groove to ensure the structural integrity.

[0060] Specifically, a threaded rod 214 is rotatably provided inside the support frame 211, and the outer wall of the threaded rod 214 is threadedly connected to the end of the transverse frame 212, and one end of the threaded rod 214 extends out of the support frame 211 and is connected to the output shaft of the rotating motor 2140, and the threaded rod 214 is driven to rotate by the output shaft of the rotating motor 2140, so that the end of the transverse frame 212 slides left and right along the thread of the outer wall of the threaded rod 214, which is convenient for changing the cutting position, wherein:

[0061] The rotary cutting assembly 210 also includes a cylinder 215 fixed to the outer wall of the limiting frame 200. The piston rod of the cylinder 215 is connected to the end of the support frame 211. The piston rod of the cylinder 215 moves linearly to drive the support frame 211 to move up and down to change the cutting height.

[0062] Furthermore, in order to realize that the metal pipe cut from the cutting groove 202 can slide along the material guide assembly 300, the structure of the material guide assembly 300 needs to be disclosed in detail, such as Figure 6 As shown, the material removal guide assembly 300 includes at least two symmetrical brackets 310 movably connected to the outer wall of the limit frame 200 through a rotating shaft, and a material removal plate 320 is connected between the two brackets 310 through a rotating shaft. The material removal plate 320 is used to adjust to an inclined state to guide the metal pipe fittings. By rotating the bracket 310 on the outer wall of the limit frame 200, the material removal plate 320 can be driven to change the support height, so as to adjust the height according to the cut metal pipe fittings. In addition, the material removal plate 320 is rotated at the end of the bracket 310 to change the inclination angle. The larger the inclination angle, the faster the metal pipe fittings roll down. As the material removal plate 320 is lifted upward, the metal pipe fittings can be limited from rolling downward, thereby increasing the scope of use. As for the rotation between the bracket 310 and the limit frame 200 through the rotating shaft, the material removal plate 320 and the bracket 310 through the rotating shaft, the rotation angle can be limited with the help of the friction resistance of the rotating shaft.

[0063] Then, to achieve the elastic separation component 230 can adjust the space in the blanking plate 320 as the cutting position changes, so that the two sections of the cut metal pipe are rolled down from the two spaces respectively, to achieve the screening effect, please refer to Fig. 9As shown, the structure of the elastic partition component 230 is further disclosed, so that the elastic partition component 230 at least includes a baffle shell 231 arranged on the outer wall of the horizontal frame 212, and an inner baffle plate 232 is slidably provided inside the baffle shell 231, and an elastic member 234 is fixedly connected between the upper end of the inner baffle plate 232 and the end of the inner cavity of the baffle shell 231, and the lower end of the inner baffle plate 232 extends out of the baffle shell 231. When the cutting position and the cutting height are changed by the horizontal frame 212, the inner baffle plate 232 is pressed against the surface of the blanking plate 320 under the elastic force compressed by the elastic member 234, so that the inner baffle plate 232 separates the blanking plate 320 into two spaces, and the separation position is the cutting position of the metal pipe fittings, so that the cut metal pipe fittings are pushed by the first arc push plate 222 to slide from the two spaces respectively, so as to realize the screening and blanking of the two sections of metal pipe fittings.

[0064] Specifically, the baffle shell 231 is movably connected to the transverse frame 212, and a plurality of brush rods 233 are fixedly connected to the lower end of the baffle inner plate 232. The baffle inner plate 232 is driven to adapt to the surface of the blanking plate 320 by rotating the baffle shell 231, so that the two are parallel to improve the separation effect, and the brush rod 233 is made to contact the surface of the blanking plate 320. As the transverse frame 212 slides, the brush rod 233 can be driven to brush the blanking plate 320, thereby avoiding the cutting debris on the blanking plate 320 from being inconvenient to clean, thereby improving convenience.

[0065] 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. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention.
