Description

Technical Field

[0001] The invention relates to the technical field of metal pipe cutting, and in particular to a metal pipe cutting device. Background Art

[0002] Metal pipe fittings are important components in the connecting pipelines of modern industrial equipment. They are widely used because of their high temperature resistance, low temperature resistance, aging resistance, and corrosion resistance. During the production and processing of metal pipe fittings, the length of the metal pipe fittings needs to be cut to suit different usage needs.

[0003] Chinese patent authorization announcement number CN115319312B discloses a large-diameter metal pipe laser cutting device with a positioning cutting function, including a fixed shell, a control module is fixedly connected to the upper part of the outer side surface of the fixed shell, the control module is connected to the handheld controller signal, and a fixing mechanism is provided on the left side of the fixed shell. By setting up the cutting mechanism, the operator is prevented from adjusting the device according to metal pipes of different diameters, thereby improving the cutting efficiency of metal pipes.

[0004] The above-mentioned existing technical solution has the following shortcomings: since the middle part of the large-diameter metal pipe is hollow, when the cutting part cuts along the circumference of the pipe, the connection area at the left and right ends of the cutting line is significantly small, so the force at the connection increases. In the device, since the cut end is not supported, the cut end is easily deformed due to pressure. At the same time, since the cut end is not supported, after cutting, the cut end is easy to fall directly to the ground, and then it is easy to cause injuries, etc., so there is room for improvement.

The rotation of the motor cooperates with the action of the incomplete toothed ring and the gear to drive the dust collection component to rotate circumferentially, thereby increasing the range of flying chip absorption. At the same time, as the front and rear ends of the tube body are separated after cutting, the outer dust collection hole of the sleeve can be directed toward the inner wall of the tube body under the elastic action of spring 2. As the motor rotates in the opposite direction, the dust collection component can further absorb the debris adhering to the inner wall of the tube body, thereby improving the effect of absorbing the debris on the inner and outer walls of the tube body.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the invention to clearly and completely describe the technical solutions in the embodiments of the invention. Obviously, the described embodiments are only part of the embodiments of the invention, not all of the embodiments. Based on the embodiments of the invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the invention.

[0032] Embodiment 1

[0033] In order to solve the problem that the existing metal pipe cutting equipment is not easy to automatically cut the cut end, the following solution is disclosed, specifically as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown:

[0034] A metal pipe cutting device comprises a table 1, a support rotating mechanism 2 is arranged on one side of the top of the table 1, a feeding mechanism 4 is arranged on the other side of the top of the table 1, and a tube 5 is passed through between the feeding mechanism 4 and the support rotating mechanism 2, a motor 6 is installed on one side of the bottom of the table 1, and a rotating shaft 7 is arranged at one end of the motor 6, and an external thread is arranged on the outside of the end of the rotating shaft 7 away from the motor 6, and one end of the rotating shaft 7 is connected to the bottom of the table 1 through a fixing plate;

[0035] The unloading mechanism 4 includes an annular frame 41 sleeved on the outside of the tube body 5, and two sets of parallel supporting rods 42 are welded at both ends of the annular frame 41. A pushing assembly 44 is arranged outside the rotating shaft 7 below the annular frame 41, and the two ends of the pushing assembly 44 are respectively connected to the outside of the supporting rod 42 close to the supporting rotating mechanism 2, and a guide assembly 43 is arranged at the top of the table 1 below the supporting rod 42 on the same side;

[0036] The guide assembly 43 includes an H-shaped frame 4301 installed on the top of the table 1, and a guide block 4302 is installed on one side of the top of the H-shaped frame 4301, and a slope 4303 is provided on one side of the guide block 4302;

[0037] The pushing assembly 44 includes a translation block 4401 threadedly sleeved on the outside of the rotating shaft 7, and vertical rods 4402 are installed on both sides of the top of the translation block 4401, and the tops of the vertical rods 4402 are connected to rectangular frames 4403, and the rectangular frames 4403 are sleeved on the outside of the support rod 42 on the same side close to the support rotation mechanism 2. In the initial state, the inner side wall of the rectangular frame 4403 is away from the support rotation mechanism 2 and abuts against the outer wall of the support rod 42;

[0038] A protective pad is provided inside the annular frame 41, and the inner diameter of the annular frame 41 is matched with the outer diameter of the tube body 5. The inner length and inner width of the rectangular frame 4403 are both greater than the diameter of the support rod 42. When the support rod 42 located inside the rectangular frame 4403 approaches the guide block 4302, the support rod 42 first moves horizontally and then contacts the slope 4303 and is gradually lifted.

[0039] The supporting rotation mechanism 2 includes a main rotating wheel 21 installed at the center of the top of the table 1, and the rotating shaft of the main rotating wheel 21 is connected to the external transmission of the lower rotating shaft 7 through a belt 22. The rotating speed of the main rotating wheel 21 is greater than the rotating speed of the rotating shaft 7. Secondary rotating wheels 23 are installed on both sides of the top of the table 1, and the two secondary rotating wheels 23 are respectively located on both sides of the main rotating wheel 21. The main rotating wheel 21 and the secondary rotating wheels 23 both support and rotate the lower side of the tube body 5. A limiting component 24 is set at the outer edge of the top of the table 1 to limit the upper side of the tube body 5.

[0040] The limiting assembly 24 includes two electric telescopic rods 2401 installed on the top of the table 1, and the two electric telescopic rods 2401 are respectively located on the side of the secondary rotating wheel 23 on the same side. A lifting plate 2402 is commonly connected between the two electric telescopic rods 2401, and the center of the lifting plate 2402 passes through a limiting pressure wheel 2403, and the outer side of the limiting pressure wheel 2403 is against the upper side of the tube body 5.

[0041] In this embodiment, when in use, the tube body 5 is placed between the main rotating wheel 21, the secondary rotating wheel 23 and the limiting pressure wheel 2403, and one end of the tube body 5 is inserted into the inside of the annular frame 41, the electric cutting seat 11 is started to lift and cut the tube body 5, and the motor 6 is started synchronously to rotate the rotating shaft 7, thereby driving the belt 22 to move, so that the main rotating wheel 21 rotates, and the main rotating wheel 21 drives the tube body 5 to rotate circumferentially, so that the electric cutting seat 11 cuts the tube body 5 circumferentially. Since the cutting ends of the tube body 5 are respectively supported by the secondary rotating wheel 23, the annular frame 41, etc. during the cutting process, deformation of the cutting part is effectively avoided to improve the cutting effect;

[0042] During the cutting process, due to the rotation of the rotating shaft 7, the translation block 4401 moves outward along the rotating shaft 7, so that the inner wall of one side of the rectangular frame 4403 is separated from the support rod 42, while the inner wall of the other side gradually approaches the support rod 42. When the tube body 5 is cut, with the continuous rotation of the rotating shaft 7, the rectangular frame 4403 pushes the support rod 42 to translate along the top end of the H-shaped frame 4301, so that the cut end of the tube body 5 and the front end of the tube body 5 are gradually separated. With the continuous movement of the rectangular frame 4403, the front support rod 42 moves to the slope 4303, so that the front support rod 42 is lifted, and then the front end of the entire annular frame 41 is lifted, so that the cut end of the tube body 5 is tilted, and the cut end slides outward along the inside of the annular frame 41 to realize the automatic unloading of the cut end of the tube body 5, and then the motor 6 is started to rotate in the opposite direction, so that the rotating shaft 7 is reversed, the support rod 42 is reset, and the annular frame 41 is driven to return to a horizontal state.

[0043] Embodiment 2

[0044] This embodiment is different from the first embodiment. The cleaning mechanism 3 is used to collect the flying debris on the outer wall of the tube body 5. In combination with the dust collecting assembly 35, the debris attached to the inner wall of the cut tube body 5 can be further collected. Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown:

[0045] An electric cutting seat 11 is arranged at the top of the table 1 between the supporting rotating mechanism 2 and the unloading mechanism 4, and a cleaning mechanism 3 is arranged at the top of the table 1 on the side of the electric cutting seat 11 close to the unloading mechanism 4, and the cleaning mechanism 3 is used to collect the waste generated by the cutting of the electric cutting seat 11;

[0046] The cleaning mechanism 3 includes a fixed ring 31 fixedly mounted on the top of the table 1, and an annular hollow tube 32 is rotatably connected inside the fixed ring 31, and the tube body 5 passes through the center of the annular hollow tube 32, and an incomplete toothed ring 33 is sleeved on the outer side of the annular hollow tube 32 near the electric cutting seat 11, and a gear 34 is sleeved on the outer side of the rotating shaft 7 below the fixed ring 31, and one side of the gear 34 and one side of the incomplete toothed ring 33 are meshed with each other, and dust collection components 35 are evenly arranged on the inner side wall of the annular hollow tube 32 near the tube body 5, and one end of the dust collection component 35 is against the outer wall of the tube body 5, and the outer side of the annular hollow tube 32 is connected with a suction pipe 36;

[0047] Two fixed blocks 9 are installed in the fixing ring 31 near the inner part of the annular hollow tube 32, and one side of the fixed block 9 is connected to a spring 8, and one end of the spring 8 is installed with a slider 10, and the inner side of the slider 10 is connected to the outer side of the annular hollow tube 32;

[0048] The teeth on the outer side of the incomplete toothed ring 33 occupy one quarter of the circumference of the incomplete toothed ring 33. Three dust collecting components 35 are provided, and the dust collecting components 35 are evenly spaced on the annular hollow tube 32. The meshing rotation of the incomplete toothed ring 33 and the gear 34 is used to stretch the spring 8 and drive the dust collecting components 35 to rotate 90 degrees along the outer wall of the tube body 5.

[0049] The dust suction assembly 35 includes a dust suction pipe 3501 that passes through the inner side of the annular hollow tube 32, and a sleeve 3504 is sleeved on the bottom end of the dust suction pipe 3501, and a pressing piece 3502 is sleeved on the outer side of the sleeve 3504 near the end of the annular hollow tube 32, and a spring 2 3503 is connected to the top of the pressing piece 3502, and the top of the spring 2 3503 is connected to the inner wall of the annular hollow tube 32, and an inner dust suction hole 3506 is opened at the bottom end of the dust suction pipe 3501 near the electric cutting seat 11, and an outer dust suction hole 3505 is opened at the bottom end of the sleeve 3504 near the electric cutting seat 11;

[0050] The bottom end of the sleeve 3504 abuts against the outer wall of the tube body 5 near the end of the feeding mechanism 4, and the outer dust suction hole 3505 and the inner dust suction hole 3506 overlap in the initial state, and the spring 2 3503 is in a compressed state in the initial state.

[0051] In this embodiment, during the rotation and cutting process of the tube body 5, due to the positive rotation of the rotating shaft 7, the gear 34 rotates and meshes with the incomplete gear ring 33, so that the annular hollow tube 32 rotates along the inner periphery of the fixed ring 31, and the external air extraction equipment is started synchronously, so that the suction pipe 36 drives the inside of the annular hollow tube 32 to generate suction, so that the dust suction component 35 rotates along the outer wall of the tube body 5, and the flying chips on the outer wall of the tube body 5 enter the inside of the annular hollow tube 32 along the outer dust suction hole 3505 and the inner dust suction hole 3506, and follow the suction pipe 36 to the inside of the subsequent collection box, so as to realize the collection of the flying chips on the outer wall of the tube body 5 during the cutting process, and at the same time, the spring 8 is gradually stretched in this process;

[0052] When the rotating shaft 7 rotates in the opposite direction, the cut-off end and the front end of the tube body 5 are separated, so that under the elasticity of the second spring 3503, the sleeve 3504 slides downward along the dust suction tube 3501, and the bottom end of the pressing plate 3502 is abutted against the outer wall of the tube body 5, and then the outer dust suction hole 3505 is directed toward the inner wall of the tube body 5. Due to the elasticity of the spring 1 8 at this time, the reverse rotation of the gear 34 can drive the incomplete gear ring 33 to engage in the opposite direction, so as to realize the reverse rotation of the annular empty tube 32, so that the sleeve 3504 rotates to the inner wall of the tube body 5 to absorb dust, thereby realizing the debris absorption effect on the inner and outer walls of the cut part of the tube body 5.
