Description

Technical Field

[0001] This invention relates to the field of materials processing technology, and more specifically, to a bar and tube cutting production line. Background Technology

[0002] With the continuous development of industrial technology, bars and tubes are increasingly widely used in various fields, such as construction, machinery manufacturing, and aerospace. In these applications, the cutting and processing of bars and tubes is a crucial step. Traditional cutting methods mainly include mechanical cutting, flame cutting, and laser cutting.

[0003] In order to improve efficiency, manufacturers usually use production lines in conjunction with cutting equipment when processing large quantities of bars and pipes.

[0004] A search revealed a Chinese patent (publication number: CN116493664A) that discloses a metal pipe cutting production line. The patent includes a cutting device, a flanging mechanism, and a feeding mechanism. The feeding mechanism is provided with a feeding position one and a feeding position two corresponding to the flanging mechanism and the cutting device, respectively. A transfer component is installed between the feeding position one and the feeding position two. The flanging mechanism is used to flanging the ends of the metal pipe.

[0005] In the prior art, when processing bars or tubes, it is necessary to continue production demand and cut them quickly. During cutting, the bars or tubes need to be in a stable state to avoid shaking. After cutting, the bars or tubes need to be transferred quickly for subsequent processing. Therefore, this invention proposes a bar and tube cutting production line. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a bar and tube cutting production line.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a bar and tube cutting production line, comprising a material placement rack and a first conveying mechanism, wherein lifting mechanisms are installed on both sides of the material placement rack, and a drive frame located inside the material placement rack is installed between the two sets of lifting mechanisms, and multiple vertically distributed material placement platforms are installed on both sides of the material placement rack near the drive frame.

[0008] A cutting box is provided on one side of the material rack. A circulating cutting frame is installed inside the cutting box. After the bar or pipe enters the cutting box, it is installed inside the circulating cutting frame for cutting.

[0009] The cutting box is equipped with side adsorption mechanisms on both sides near the circulating cutting frame. When processing bars or tubes, the two sets of side adsorption mechanisms cover the outside of the cutting part to filter the debris and dust generated during cutting.

[0010] The first conveying mechanism passes through the inside of the material rack and extends to one side of the cutting box;

[0011] A connecting frame extending to the upper side of the cutting box is installed on the upper side of the first conveying mechanism. A cutting unit is installed inside the connecting frame, and a conveying mechanism is installed on the side of the connecting frame near the cutting unit. The conveying mechanism moves the bar or tube from the first conveying mechanism to the circulating cutting frame.

[0012] Furthermore, the circulating cutting frame includes a rotating frame, which includes a drive unit and a support unit;

[0013] The drive unit is connected to the inner wall of the cutting box, one end of the support unit is rotatably connected to the cutting box, and the other end is connected to the output end of the drive unit;

[0014] Furthermore, fixed brackets are installed on both the upper and lower sides of the drive unit, which serve as the output ends of the rotating frame;

[0015] The interior of the fixture is divided into multiple finished product zones based on the required cutting length of the bar or tube material.

[0016] Multiple finished product areas are separated by a cutting area;

[0017] Each finished product area is equipped with multiple adsorption components. When the bar or tube is cut, it is fixed inside the finished product area in the corresponding fixing frame by the adsorption components.

[0018] Each cutting zone has a cutting groove on its lower side. The side of the fixing frame is equipped with a connecting frame on both sides of the cutting groove. The sides of the connecting frame are all frame-shaped and are in a connected state.

[0019] Furthermore, the side adsorption mechanism includes an extension assembly connected to the cutting box, the output end of the extension assembly is equipped with an adsorption box, and the inside of the adsorption box is equipped with a filter assembly for filtering the debris and dust generated during cutting.

[0020] The adsorption box has an assembly frame installed on each of the cutting areas of the fixing frame on the side by multiple elastic reset parts.

[0021] Both sides of the assembly frame have connecting ports. After the adsorption box moves to one side of the fixed frame, the assembly frame contacts the connecting frame and the assembly frame communicates with the connecting frame through the connecting ports.

[0022] Furthermore, the drive frame includes two sets of connecting plates, which are respectively connected to the output ends of two sets of lifting mechanisms, and a horizontal moving component is installed between the two sets of connecting plates. A clamping frame is installed at the output end of the horizontal moving component, and the clamping frame is used for assembling with bars or tubes.

[0023] Driven by the connecting plate, the horizontal moving component moves vertically between the material placement platforms of different heights. After moving to the required height, the horizontal moving component drives the clamping frame to move horizontally, moving the bar or tube horizontally to the material placement platform of the corresponding height, and temporarily placing the bar or tube in the material placement platform.

[0024] Furthermore, the cutting unit includes at least one set of stroke cylinders connected to the connecting frame, with the output end of the stroke cylinder facing downwards and a cutting module installed thereon.

[0025] Furthermore, the conveying mechanism includes two sets of horizontal drive units, which are respectively arranged on both sides of the cutting unit, and axial drive units are installed at the output ends of both sets of horizontal drive units, and conveying frames are installed at the output ends of both sets of axial drive units.

[0026] When handling bars or tubes, the transport frame is assembled with the bars or tubes, and the axial drive unit lowers the height of the transport frame to the underside of the cutting module. Then, the horizontal drive unit drives the transport frame to move horizontally to the underside of the cutting module, placing the bars or tubes into the corresponding rotating frame.

[0027] Furthermore, a plurality of second conveying mechanisms are provided on one side of the cutting box, each of which corresponds to a group of finished product areas in the rotating frame.

[0028] Each of the second conveying mechanisms includes a unit box, inside which a guide frame is installed. The top of the guide frame extends into the interior of the cutting box and is located below the circulating cutting frame. After the bar or tube is processed into shape, the rotating frame in the circulating cutting frame rotates to the upper side of the guide frame and separates from the bar or tube. The bar or tube slides along the corresponding guide frame into the unit box.

[0029] The unit box is equipped with a conveyor frame, one end of which extends to the lower side of the guide frame for transporting the processed bars or pipes.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] Compared with the prior art, the present invention uses a production line to cut and process a large number of bars or tubes. When processing bars or tubes, the bar or tubes to be processed later can be temporarily stored through the material rack and material table, which facilitates the production management of bars or tubes.

[0032] Furthermore, during cutting, the rotating frame in the circulating cutting frame is equipped with two sets. After cutting the bar or tube, the processing position can be quickly changed, thereby improving processing efficiency. Each rotating frame is equipped with a finished product area and a cutting area. In the finished product area, the bar or tube can be adsorbed and fixed, maintaining stability during processing. When adjusting the position, it can prevent the bar or tube from falling off the rotating frame.

[0033] Furthermore, during cutting, the side adsorption mechanism is fitted outside the cutting area of ​​the rotating frame, which can filter the debris and dust generated during processing and prevent them from polluting the working environment. Attached Figure Description

[0042] Reference Figures 1 to 7As shown, a bar and tube cutting production line includes a material rack 1 and a first conveying mechanism 5. Lifting mechanisms 3 are installed on both sides of the material rack 1. A drive frame 4 located inside the material rack 1 is installed between the two sets of lifting mechanisms 3. Multiple vertically distributed material placement platforms 2 are installed on both sides of the material rack 1 near the drive frame 4.

[0043] A cutting box 6 is provided on one side of the material rack 1. A circulating cutting frame 7 is installed inside the cutting box 6. After the bar or pipe enters the cutting box 6, it is installed inside the circulating cutting frame 7 for cutting.

[0044] Inside the cutting box 6, on both sides near the circulating cutting frame 7, there are side adsorption mechanisms 8. When processing bars or tubes, the two sets of side adsorption mechanisms 8 are placed on the outside of the cutting area to filter the chips and dust generated during cutting.

[0045] The first conveying mechanism 5 passes through the inside of the material rack 1 and extends to one side of the cutting box 6;

[0046] A connecting frame 9 extending to the upper side of the first conveying mechanism 5 is installed on the upper side of the cutting box 6. A cutting unit 11 is installed inside the connecting frame 9, and a conveying mechanism 10 is installed on the side of the connecting frame 9 near the cutting unit 11. The conveying mechanism 10 moves the bar or tube from the first conveying mechanism 5 to the circulating cutting frame 7.

[0047] Multiple second conveying mechanisms 12 are provided on one side of the cutting box 6.

[0048] Reference Figures 2 to 4 As shown, the circulating cutting frame 7 includes a rotating frame 71, and the rotating frame 71 includes a drive unit and a support unit;

[0049] The drive unit is connected to the inner wall of the cutting box 6, one end of the support unit is rotatably connected to the cutting box 6, and the other end is connected to the output end of the drive unit;

[0050] Furthermore, the upper and lower sides of the drive unit, which serve as the output ends of the rotating frame 71, are each equipped with a fixed frame 72;

[0051] The interior of the fixture 72 is divided into multiple finished product zones based on the required cutting length of the bar or tube.

[0052] Multiple finished product areas are separated by a cutting area;

[0053] Each finished product area is equipped with multiple adsorption components 73. When the bar or tube is cut, it is fixed inside the finished product area in the corresponding fixing frame 72 by each adsorption component 73.

[0054] Each cutting area has a cutting groove 74 on its lower side. The side of the fixing frame 72 is equipped with a connecting frame 75 on both sides of the cutting groove 74. The sides of the connecting frame 75 are all frame-shaped and are in a connected state.

[0055] The side adsorption mechanism 8 includes an extension assembly 81 connected to the cutting box 6. An adsorption box 82 is installed at the output end of the extension assembly 81. A filter assembly is installed inside the adsorption box 82 to filter the debris and dust generated during cutting.

[0056] Both sides of the inside of the cutting box 6 are equipped with exhaust mechanisms, and the two exhaust mechanisms are respectively connected to the adsorption box 82 in the corresponding direction.

[0057] The extension component 81 includes a bidirectional lead screw drive assembly, which includes a housing, a lead screw portion and a drive portion. The drive portion is connected to the lead screw portion, and both are housed inside the housing. A groove is provided on one side of the housing.

[0058] The two ends of the bidirectional lead screw drive assembly are connected to the adsorption box 82 through two sets of transmission rods. The transmission rod includes a threaded sleeve part connected to the lead screw part, a rod body part rotatably connected to one side of the threaded sleeve part, the rod body part slidably connected to the sliding groove of the housing, and the other end of the rod body part rotatably connected to the adsorption box 82.

[0059] After startup, the bidirectional screw drive assembly drives the adsorption box 82 to move horizontally to one side of the circulating cutting frame 7 via two sets of transmission rods;

[0060] The sides of the adsorption box 82, corresponding to each cutting area of ​​the fixing frame 72, are equipped with assembly frames 83 by multiple elastic reset parts 84.

[0061] Both sides of the assembly frame 83 have connecting ports. After the adsorption box 82 moves to one side of the fixing frame 72, the assembly frame 83 contacts the connecting frame 75 and the assembly frame 83 is connected to the connecting frame 75 through the connecting ports.

[0062] Reference Figure 5 As shown, the drive frame 4 includes two sets of connecting plates 41, which are respectively connected to the output ends of two sets of lifting mechanisms 3. A horizontal moving component 42 is installed between the two sets of connecting plates 41. A clamping frame 43 is installed at the output end of the horizontal moving component 42. In this embodiment, the clamping frame 43 adopts a mechanical claw structure for handling.

[0063] Driven by the connecting plate 41, the horizontal moving component 42 moves vertically between the material placement platforms 2 at different heights. After moving to the required height, the horizontal moving component 42 drives the clamping frame 43 to move horizontally, moving the bar or tube horizontally to the material placement platform 2 at the corresponding height, and temporarily placing the bar or tube in the material placement platform 2.

[0064] Reference Figure 6 As shown, the cutting unit 11 includes at least one set of stroke cylinders 111 connected to the connecting frame 9. The output end of the stroke cylinder 111 faces downward and is equipped with a cutting module 112.

[0065] The conveying mechanism 10 includes two sets of horizontal drive units 101, which are respectively arranged on both sides of the cutting unit 11. An axial drive unit 102 is installed at the output end of each set of horizontal drive units 101, and a conveying frame 103 is installed at the output end of each set of axial drive units 102. In this embodiment, the conveying frame 103 uses an adsorption structure to convey the bar or tube.

[0066] When handling bars or tubes, the handling frame 103 is assembled with the bars or tubes, and the axial drive unit 102 lowers the height of the handling frame 103 to the lower side of the cutting module 112. Then, the horizontal drive unit 101 drives the handling frame 103 to move horizontally to the lower side of the cutting module 112, and places the bars or tubes into the corresponding rotating frame 71.

[0067] The cutting module 112 includes a cutting component and a housing component. The cutting component is installed inside the housing component. Before the cutting component contacts the bar or tube, the housing component contacts the corresponding fixing frame 72.

[0068] Furthermore, the housing assembly includes a fixed housing and a movable housing. The movable housing is mounted on the lower side of the fixed housing via multiple elastomers. After contacting the corresponding fixed frame 72, the movable housing slides along the fixed housing via the compression elastomers. When sealing the top of the corresponding fixed frame 72, the cutting assembly can still cut the bar or tube.

[0069] Reference Figure 7 As shown, each of the second conveying mechanisms 12 corresponds to a set of finished product areas in the rotating frame 71;

[0070] Each of the second transmission mechanisms 12 includes a unit box 121;

[0071] Inside the unit box 121, a guide frame 122 is installed. The top of the guide frame 122 extends into the interior of the cutting box 6 and is located on the lower side of the circulating cutting frame 7. After the bar or tube is processed and formed, the rotating frame 71 in the circulating cutting frame 7 rotates to the upper side of the guide frame 122 and separates from the bar or tube. The bar or tube slides along the corresponding guide frame 122 into the unit box 121.

[0072] The unit box 121 is equipped with a conveyor frame 123, one end of which extends to the lower side of the guide frame 122 for transporting the processed bars or pipes.

[0073] Working principle:

[0074] Before processing, the bar stock or tube is placed in the transport box and transported to the lower side of the placement rack 1 by the first conveying mechanism 5. The drive frame 4 is vertically lowered to the upper side of the transport box by the lifting mechanism 3 and assembled with the transport box by the clamping frame 43. Then, the lifting mechanism 3 raises the drive frame 4 to the required height, and the clamping frame 43 is activated to move the transport box to the corresponding placement platform 2.

[0075] When processing is required, the lifting mechanism 3 and the drive frame 4 move the corresponding bar or tube transport box to the first conveying mechanism 5. The first conveying mechanism 5 moves it to the lower side of the connecting frame 9. The horizontal drive unit 101 in the handling mechanism 10 moves the axial drive unit 102 and the handling frame 103 to the upper side of the transport box. Then the axial drive unit 102 lowers the handling frame 103 to the upper side of the transport box. The handling frame 103 is assembled with the bar or tube inside the transport box and then transported to the upper fixed frame 72 in the circulating cutting frame 7.

[0076] The various adsorption components 73 inside the finished product area of ​​the fixed frame 72 are activated to fix the rods or tubes inside the fixed frame 72;

[0077] Then the extension component 81 in the side adsorption mechanism 8 is activated, covering the adsorption box 82 to the side of the upper fixed frame 72, fitting the assembly frame 83 onto the outside of the connecting frame 75, and the exhaust mechanism is activated.

[0078] Then the cutting unit 11 is activated to cut the bar or tube;

[0079] After cutting, the rotating frame 71 rotates, swapping the positions of the two sets of fixed frames 72, flipping the cut bars or tubes onto the upper side of each guide frame 122, and then the adsorption components 73 in the corresponding fixed frames 72 close, causing the bars or tubes to fall onto the guide frames 122 in the corresponding second conveying mechanism 12, slide along the guide frames 122 to the conveyor frame 123, and be transported by the conveyor frame 123.
