Description

Technical Field

[0001] The present invention relates to the field of slitting of aluminum alloy pipes, and particularly to a slitting device for processing aluminum alloy pipes. Background Art

[0002] Pipes are essential materials for construction projects. Commonly used ones include water supply pipes, drainage pipes, gas pipes, heating pipes, wire conduits, rainwater pipes, etc. There are many types of pipes. Among them, aluminum alloy pipes are one of the most widely used non-ferrous metal structural materials in industry. Due to the high strength of aluminum alloy pipes, they are not easy to rust. Compared with ordinary steel, they are lighter in weight and have been widely used in aviation, aerospace, automobiles, machinery manufacturing, ships, construction, decoration, and chemical industries.

[0003] According to the patent application with the publication number CN111590353B, an aluminum alloy pipe cutting device is disclosed. It is through: the middle of the horizontal plate of the U-shaped plate is fixedly connected to the cross bar of the U-shaped rod. One end of each of the two vertical rods of the U-shaped rod is fixedly connected to one end of the first guide rod. One end of one of the vertical rods of the U-shaped rod is fixedly connected to the first motor. The output shaft of the first motor is fixedly connected to one end of the first screw rod. The other end of the first screw rod is movably connected to the other vertical rod of the U-shaped rod. One end of each of the two vertical rods of the U-shaped rod is fixedly connected to one end of the second guide rod. The screw rod is threadedly connected to the cutting mechanism, so as to realize the pressing of both ends of the aluminum alloy pipe, and thus there is no need for manual fixation.

[0004] However, aluminum alloy pipes are divided into round pipes and rectangular pipes. This method has a good effect on round pipes but not on rectangular pipes. And after clamping both ends of the pipe and then cutting, it is impossible to effectively perform multi-segment cutting on the pipe. Workers need to remove the cut pipe and re-fix both ends of it to perform the next cut. This method undoubtedly increases the workload of workers and has low efficiency. Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems in the above technologies to a certain extent.

[0006] To achieve the above object, a first aspect of the present invention provides a slitting device for processing aluminum alloy pipes, including: a frame. It is characterized in that an inwardly concave installation groove is provided on the frame. One end of the top of the frame is provided with a support frame. A support plate is movably arranged inside the support frame. A strip of teeth is fixedly arranged at the bottom of the support plate. The cutting device is fixedly arranged on the support plate.

[0009] Furthermore, the support frame also includes: guide rods are fixedly arranged on both sides of the support frame, the guide rods are vertically arranged on the top of the frame, and both sides of the support plate pass through the support frame and are sleeved on the outer walls of the two guide rods.

[0010] Furthermore, the support plate is movably arranged inside the support frame through a telescopic rod, the telescopic rod is fixedly arranged on the top of the support frame, and the movable end of the telescopic rod passes through the support frame and is connected to the support plate.

[0014] According to the cutting device for aluminum alloy pipe processing of the present invention, the support plate can be driven to move up and down by the telescopic rod, so that the cutting device can cut the aluminum alloy pipe fitting located below it.

[0028] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0029] The slitting device for processing aluminum alloy pipes according to the embodiment of the present invention will be described below with reference to the drawings.

[0030] As Figures 1 to 9 shown, the slitting device for processing aluminum alloy pipes according to the embodiment of the present invention may include: a frame 1. It is characterized in that an inwardly concave installation groove 11 is provided on the frame 1, a support frame 2 is provided at one end of the top of the frame 1, a support plate 21 is movably arranged inside the support frame 2, a strip tooth 3 is fixedly arranged at the bottom of the support plate 21, a cutting device 4 is fixedly arranged on the support plate 21, a plurality of conveyor rollers 5 are equidistantly arranged in the installation groove 11, and a ratchet device 6 is arranged at one end of the conveyor roller 5 on one side of the frame 1. When the support plate 21 moves, it will drive the ratchet device 6 to rotate through the strip tooth 3.

[0031] It can be understood that when an aluminum alloy pipe to be cut is placed on the top of the conveyor roller 5 and one end is located at the bottom of the cutting device 4, at this time, the telescopic rod 7 and the driving motor 41 are started. At this time, the telescopic rod 7 will drive the support plate 21 to move towards the pipe direction, and the driving motor 41 will drive its cutting knife 44 to rotate through the transmission shaft 43. And during the movement of the support plate 21, the strip tooth 3 arranged at its bottom will drive its transmission gear 62 to rotate. Since the rotation direction of the transmission gear 62 is the same as the meshing direction of its pawl 613, the pawl 613 will not mesh with its ratchet tooth 621, so that the transmission gear 62 will rotate idly.

[0032] When the cutting knife 44 gradually approaches the pipe, the pressure rod 45 will press against the top of the pipe in advance, and as the support plate 21 descends, the spring 451 arranged thereon will be gradually compressed. When the cutting knife 44 contacts the pipe, it will cut it and cut off the pipe as it moves.

[0033] When the cutting is completed, the telescopic rod 7 is reset and drives the support plate 21 to move upward. At this time, the support plate 21 will drive the bar teeth 3 to move upward together, and the bar teeth 3 will drive its transmission teeth 62 to reverse, so that its ratchet teeth 621 are engaged with its pawl 613, so that the rotating transmission teeth 62 drive the limit shaft 61 to rotate together, and drive the transmission roller 5 connected to it to rotate together, and the rotating transmission roller 5 will drive the remaining transmission rollers 5 to rotate together through the synchronous wheel 53 and its second synchronous belt 8, so that the pipe at the top of the transmission roller 5 is moved toward the cutting knife 44, and the above steps are repeated for the next cutting.

[0034] like Figures 1 to 3 As shown, the slitting device for aluminum alloy pipe processing of the embodiment of the present invention may include: a support leg 12 and a baffle 13 are arranged at the bottom of the frame 1, wherein the baffle 13 is L-shaped, and is movably arranged at the bottom of the frame 1 through a slide groove and a limit screw, and the moving end of the baffle 13 is on the side of the cutting device 4, and a through-hole paving groove 14 is also opened on the frame 1, and the bottom of the bar tooth 3 is located in the paving groove 14.

[0035] It can be understood that the support legs 12 arranged at the bottom of the frame 1 can make the frame 1 off the ground and provide sufficient moving space for its bar teeth 3. By adjusting the distance between the baffle 13 and the frame 1, the distance of the pipe cutting can be consistent each time. The clearance groove 14 is used to enable the bar teeth 3 to pass through the frame 1 and drive the ratchet device 6 to rotate.

[0036] like Figure 1 Figure 2 As shown, the slitting device for aluminum alloy pipe processing in an embodiment of the present invention may include: guide rods 22 are fixedly arranged on both sides of the support frame 2, the guide rods 22 are vertically arranged on the top of the frame 1, and the support plates 21 on both sides pass through the support frame 2 and are sleeved on the outer walls of the two guide rods 22.

[0037] It can be understood that the guide rod 22 can constrain the support plate 21 to prevent it from deviating when moving.

[0038] like Figure 2 Figure 4As shown in the figure, the slitting device for processing aluminum alloy pipes according to the embodiment of the present invention may include: The support plate 21 is movably arranged inside the support frame 2 through the telescopic rod 7. The telescopic rod 7 is fixedly arranged on the top of the support frame 2, and the moving end of the telescopic rod 7 passes through the support frame 2 and is connected to the support plate 21.

[0039] It can be understood that when the telescopic rod 7 is started, the moving end of the telescopic rod 7 will drive its support plate 21 to move, so that the support plate 21 descends and ascends.

[0040] Furthermore, it should be noted that the cutting device 4 includes: a driving motor 41, a synchronous belt 42, a transmission shaft 43, a cutting knife 44 and a pressing rod 45. Among them, the driving motor 41 and the transmission shaft 43 are respectively arranged on the support plate 21 through mounting brackets. The cutting knife 44 is located on one side of the frame 1, and the cutting knife 44 is concentrically arranged at one end of the transmission shaft 43. The output end of the driving motor 41 is connected to the end of the transmission shaft 43 away from the cutting knife 44 through the synchronous belt 42. The pressing rod 45 is arranged on the support plate 21 in an I-shaped manner, and a spring 451 is wound on the outer wall of the pressing rod 45.

[0041] It can be understood that when the driving motor 41 is started, the output end of the driving motor 41 will drive its transmission shaft 43 to rotate through the synchronous belt 42, so that the cutting knife 44 arranged on the transmission shaft 43 rotates, thereby achieving the purpose of cutting the pipe. The pressing rod 45 can press the pipe when the cutting knife 44 cuts the pipe, so as to prevent it from moving during the cutting process and affecting the cutting effect.

[0042] As Figure 2 and Figure 5 As shown in the figure, the slitting device for processing aluminum alloy pipes according to the embodiment of the present invention may include: Synchronous wheels 53 are respectively arranged on one side of a plurality of conveying rollers 5. A plurality of second synchronous belts 8 connect the plurality of conveying rollers 5 in pairs through the synchronous wheels 53. The conveying roller 5 further includes: a tapered block 51 and a throat tube 52. Among them, the synchronous wheel 53 is fixedly arranged at one end of the tapered block 51. The contraction ends of the two tapered blocks 51 are respectively arranged at both ends of the throat tube 52 in a mirror image manner. The ends of the two tapered blocks 51 away from the throat tube 52 are respectively pivotally connected to the side wall of the installation groove 11.

[0043] It can be understood that the two tapered blocks 51 are arranged at both ends of the throat tube 52 in a mirror image manner, so that the pipe placed on it is located between the two tapered blocks 51 and plays a certain limiting role. Rubber pads can be arranged on the surface of the tapered blocks 51 to increase the friction between it and the pipe, so as to drive the pipe to move more stably. The synchronous wheels 53 and the second synchronous belts 8 arranged on one side of it can make the plurality of conveying rollers 5 rotate together.

[0044] As Figures 6 to 9As shown in the figure, the slitting device for processing aluminum alloy tubes according to the embodiment of the present invention may include: a ratchet device 6, where the ratchet device 6 includes: a limiting shaft 61 and a transmission gear 62. The limiting shaft 61 is fixedly arranged at one end of the conveying roller 5 away from the synchronous wheel 53. A plurality of grooves 611 are formed in the side wall of the limiting shaft 61 along the circumference. A reed 612 and a pawl 613 are respectively arranged in the grooves 611. The transmission gear 62 is sleeved on the limiting shaft 61, and the transmission gear 62 meshes with the strip teeth 3. A ratchet tooth 621 is arranged inside the transmission gear 62, and the ratchet tooth 621 meshes with the pawl 613.

[0045] It can be understood that, taking Figure 6 as an example, when the transmission gear 62 rotates clockwise, the ratchet tooth 621 inside the transmission gear 62 will not mesh with its pawl 613. At this time, the transmission gear 62 will rotate idly. When the rotating gear 62 rotates counterclockwise, the ratchet tooth 621 meshes with its pawl 613. At this time, the transmission gear 62 will drive its limiting shaft 61 to rotate together through the pawl 613.

[0046] In summary, the slitting device for processing aluminum alloy tubes according to the embodiment of the present invention can reduce the workload of its staff, and is highly efficient, and can work for tubes of different shapes.
