Description

Technical Field

[0001] This utility model relates to the field of automatic chamfering technology, and in particular to an automatic unloading chamfering device and production line. Background Technology

[0002] Pipe processing is widely used in industrial production, and the chamfering process is a key step. Although traditional chamfering machines can complete the chamfering operation, they require manual material handling, which is inefficient and labor-intensive. This process is not only time-consuming but also prone to downtime and waiting, affecting the production line rhythm. During the pipe handling process, the pipe may be damaged or safety accidents may occur, increasing production risks. Therefore, the limitations of traditional chamfering machines are becoming increasingly apparent, and there is an urgent need to develop a chamfering device with automatic unloading that can automatically unload the material after the chamfering process is completed, thus achieving full automation of the production process. Utility Model Content

[0003] The main purpose of this invention is to propose an automatic unloading chamfering device and production line, which aims to solve the technical problem that existing chamfering devices require manual unloading.

[0004] To achieve the above objectives, this utility model proposes an automatic unloading chamfering device, including a frame, on which a positioning frame, a clamping mechanism, a pushing plate and a chamfering machine are provided. The positioning frame includes two baffles, which extend vertically and are respectively installed on the left and right sides of the frame. The lower side of each baffle is provided with a material passage, which faces backward and is on the same horizontal line.

[0005] The clamping mechanism includes an upper clamping block, a lower clamping block, and a clamping drive device. The upper clamping block and the lower clamping block are arranged opposite each other. The upper clamping block is fixedly installed on the baffle. The lower clamping block is connected to the clamping drive device. The clamping drive device can drive the lower clamping block to move closer to or away from the upper clamping block, so that the clamping mechanism opens and closes.

[0006] The pusher plate is located inside the positioning frame. The pusher plate extends in the front-to-back direction. The pusher plate is provided with a material holding groove and a pusher driving device. The material holding groove opens upward to accommodate pipes. The pusher plate is slidably connected to the frame. The pusher driving device is drively connected to the pusher plate and can drive the pusher plate to move back and forth.

[0007] The chamfering machine is located on the left and right sides of the frame.

[0008] The clamping mechanism facilitates alignment between the pipe and the chamfering machine's chamfering edge, maintaining stability during chamfering. The positioning frame can hold multiple pipes, enabling continuous chamfering and improving work efficiency. The pusher plate facilitates pipe feeding, chamfering, and unloading. The left and right chamfering machines can simultaneously chamfer the left and right ends of the pipe. The combined use of these mechanisms enables the chamfering equipment to achieve automated chamfering and automated unloading.

[0009] Preferably, the clamping mechanism is disposed inside the positioning frame, and at least two sets of the clamping mechanism are provided, with the two sets of clamping mechanisms respectively disposed on the left and right sides inside the positioning frame.

[0010] The clamping mechanisms on both sides can enhance clamping stability and firmness, reduce the possibility of pipe shifting, shaking or rotating during clamping, and improve processing accuracy.

[0011] Preferably, the clamping mechanism is provided with a stop seat, which is located inside the clamping mechanism.

[0012] The stop provides support for the pipe to be cut, further improving the stability of the pipe. On the other hand, its location inside the clamping mechanism does not affect the chamfering operation.

[0013] Preferably, the pusher plate is disposed between the clamping mechanism and the baffle, and at least two sets of pusher plates are provided, with each pusher plate having at least two material troughs.

[0014] The pusher plate is positioned between the clamping mechanism and the baffle, making efficient use of space. The material trough on the pusher plate and the clamping mechanism of the chamfering process are well connected, forming a highly efficient automated production line.

[0015] Preferably, a discharge block is fixedly installed on the clamping mechanism. The discharge block includes a vertical plate and a discharge plate. The vertical plate is vertically arranged, with its bottom connected to the lower clamping block and its top connected to the discharge plate. The discharge plate extends in a diagonally rearward direction, and its front height is greater than its rear height.

[0016] The unloading block can be used in conjunction with the pusher plate and clamping mechanism to achieve automatic unloading and complete unloading automation.

[0017] Preferably, the chamfering machine is equipped with a chamfering drive device, which is connected to the chamfering machine in a transmission manner. The chamfering machine is slidably connected to the frame, and the chamfering drive device can drive the chamfering machine to move in the left and right directions.

[0018] The chamfering machine can move left and right to adapt to chamfering pipes of different lengths, meeting the chamfering requirements of pipes of different specifications.

[0019] Preferably, the inner side of the baffle is provided with two limiting plates, which extend vertically and are respectively located on the front and rear sides of the baffle.

[0020] The installation of a limit plate can precisely restrict the position of the pipe and improve the stability of the equipment.

[0021] On the other hand, this utility model proposes a production line in which the automatic unloading chamfering device and the cutting device group are connected by a conveyor belt, so that the pipes cut by the cutting device can be fed into the automatic unloading chamfering device. The automatic unloading chamfering device and the cutting device form a set of process machine tools.

[0022] The chamfering and cutting equipment with automatic unloading are connected by a conveyor belt to form a complete automated production process. The pipes can be automatically transferred from the cutting equipment to the chamfering equipment without manual intervention, which improves production efficiency and realizes automated continuous production.

[0023] Preferably, the frame is divided into a fixed frame and a movable frame, and the movable frame is slidably connected to the machine tool.

[0024] The mobile frame allows for flexible movement, facilitating chamfering operations on pipes of different lengths.

[0043] like Figure 1 As shown in Figure 7, an automatic unloading chamfering device includes a frame 1, a positioning frame 2, a clamping mechanism 3, a pushing plate 4 and a chamfering machine 5. The positioning frame 2 includes two baffles 21, which extend vertically and are respectively installed on the left and right sides of the frame 1. The lower side of each baffle 21 is provided with a material passage 211, and the two material passages 211 open backward and are on the same horizontal line.

[0044] The clamping mechanism 3 includes an upper clamping block 31, a lower clamping block 32, and a clamping drive device 33. The upper clamping block 31 and the lower clamping block 32 are arranged opposite each other. The upper clamping block 31 is fixedly installed on the baffle 21. The lower clamping block 32 is connected to the clamping drive device 33. The clamping drive device 33 can drive the lower clamping block 32 to move closer to or away from the upper clamping block 31, so that the clamping mechanism 3 opens or closes.

[0045] The pusher plate 4 is located inside the positioning frame 2. The pusher plate 4 extends in the front-to-back direction. The pusher plate 4 is provided with a material trough 41 and a pusher drive device 42. The material trough 41 opens upward and can hold the pipe 7. The pusher plate 4 is slidably connected to the frame 1. The pusher drive device 42 is connected to the pusher plate 4 in a transmission manner. The pusher drive device 42 can drive the pusher plate 4 to move back and forth.

[0046] The chamfering machine is located on the left and right sides of the frame.

[0047] The clamping mechanism 3 facilitates the alignment of the pipe 7 with the chamfering opening 51 of the chamfering machine 5 and maintains the stability of the pipe 7 during chamfering. The positioning frame 2 can hold multiple pipes 7, enabling the pipes 7 to be chamfered continuously, thus improving work efficiency. The pusher plate 4 facilitates the feeding, chamfering, and unloading of the pipes 7. The left and right chamfering machines 5 can simultaneously chamfer the left and right ends of the pipes 7. The cooperation of the above multiple mechanisms enables the chamfering equipment 65 to achieve automated chamfering and automated unloading.

[0048] The chamfering machine 5 is located on the left and right sides of the positioning frame 2, and the chamfering opening 51, the material passage 211 and the clamping center of the clamping mechanism 3 of the chamfering machine 5 are on the same horizontal line.

[0049] The positioning frame 2 consists of two baffles 21 on the left and right sides, which are arranged opposite each other. The material inlet 211 faces backward to facilitate unloading of the pipe 7 from the rear. The pipe 7 to be chamfered is placed between the baffles 21 for chamfering. The pushing drive device 42 is a cylinder. The pushing plate 4 is provided with a material holding groove 41. The front side of the pushing plate 4 is fixedly connected to a first slider 47, which is slidably connected to the first guide rail 43 on the frame 1 to ensure the forward and backward movement direction. The pushing plate 4 is also provided with a first rack 46, which meshes with a first gear 44 fixedly installed on the frame 1 to keep the pushing plate 4 stable when moving. The tube 7 at the bottom of the positioning frame 2 enters the material holding trough 41. The material holding trough 41 moves forward, sending the tube 7 to the clamping mechanism 3. The lower clamping block 32 is driven upward by the clamping drive device 33, causing the clamping mechanism 3 to close and clamp the tube 7. The chamfering machine 5 begins chamfering. After completion, the clamping mechanism 3 releases, and the lower clamping block 32 lowers with the tube 7 until the tube 7 lands on the material holding trough 41. The lower clamping block 32 descends to a height lower than the level of the pusher plate 4 to prevent the lower clamping block 32 from obstructing the pusher plate 4 when it moves back and forth. After the tube 7 lands on the material holding trough 41, the pusher plate 4 moves backward to push the tube 7 out, and then unloads the tube 7. After unloading, the tube 7 is returned to the bottom of the positioning frame 2 for material holding, and the cycle continues.

[0050] like Figure 1-3 As shown, in some specific embodiments, the clamping mechanism 3 is located inside the positioning frame 2, and there are two sets of clamping mechanisms 3, which are respectively located on the left and right sides inside the positioning frame 2.

[0051] The clamping mechanisms 3 on both sides can enhance clamping stability and firmness, reduce the possibility of pipe 7 shifting, shaking or rotating during clamping, and improve processing accuracy.

[0052] The clamping mechanism 3 is located inside the left and right baffles 21. The two clamping mechanisms are arranged opposite to each other. The first shaft 321 is installed on the lower clamping block 32 and passes vertically through the linear bearing 322 on the frame 1. The clamping drive device 33 drives the first shaft 321 to move, thereby driving the lower clamping block 32 to move in the vertical direction to ensure a vertical movement path.

[0053] like Figure 3 As shown, the clamping drive device 33 is a crank-slider mechanism drive device. A first guide rod 331 is used to connect the discs 332 below the two sets of clamping mechanisms 3. The other side of the first guide rod 331 is rotatably connected to the clamping motor 334. The upper and lower clamping blocks 32 of the disc 332 are connected by a connecting rod 333.

[0054] When the clamping motor 334 rotates, it drives the two discs 332 to rotate simultaneously through the first guide rod 331. The discs 332 drive the connecting rod 333 to rotate, causing the lower clamping block 32 to move. The first shaft 321 and the linear bearing 322 limit the movement of the lower clamping block 32, making it move vertically.

[0055] like Figure 1-4 As shown in 7a-7e, in some specific embodiments, the clamping mechanism 3 is provided with a stop seat 34, which is located inside the clamping mechanism 3.

[0056] The stop seat 34 provides support for the pipe 7 to be cut, further improving the stability of the pipe 7. On the other hand, it is located inside the clamping mechanism 3 and does not affect the chamfering operation.

[0057] The baffle seat 34 has a rectangular structure. When the pusher plate 4 transports the pipe 7 to the clamping mechanism 3, the clamping mechanism 3 begins to close, the lower clamping block 32 moves upward to catch the pipe 7, the lower clamping block 32 fits against the pipe 7, the clamping mechanism 3 closes and clamps the pipe 7, the main body of the pipe 7 rests on the baffle seat 34, and together with the lower clamping block 32, supports the pipe 7, thereby further improving the stability of the pipe 7 when chamfering.

[0058] like Figure 1-4 As shown in 7a-7e, in some specific embodiments, the pusher plate 4 is disposed between the clamping mechanism 3 and the baffle 21, and the pusher plate 4 is provided in at least two sets, with each pusher plate 4 having at least two material holding grooves 41.

[0059] The pusher plate 4 is located between the clamping mechanism 3 and the baffle 21, making reasonable use of space. The material trough 41 on the pusher plate 4 is well connected with the material feeding process before the chamfering, forming an efficient automated production line.

[0060] A second guide rod 45 connects the first gears 44 on both the left and right sides, enabling the two first gears 44 to rotate synchronously, facilitating the synchronous movement of the pusher plate 4 and improving the accuracy of the equipment. A material trough 41 is provided on each of the front and rear sides of the pusher plate 4. When the pusher plate 4 is in the forward position without material, it is pushed backward so that the rear material trough 41 first catches the pipe 7. Continuing to push the material trough 41 backward, the pipe 7 in the rear material trough 41 enters the chamfering process, while the front material trough 41 catches the pipe 7. After the pipe 7 in the rear material trough 41 is chamfered, the pusher plate 4 continues to move backward, unloading the pipe 7 from the chamfering machine 5. The pipe 7 in the front material trough 41 then enters the chamfering process. After both material troughs 41 have completed chamfering and unloading, the pusher plate 4 returns to its initial position to prepare for the next operation.

[0061] like Figure 4 , 7a As shown in -7e, in some specific embodiments, a discharge block 35 is fixedly installed on the clamping mechanism 3. The discharge block 35 includes a vertical plate 351 and a discharge plate 352. The vertical plate 351 is vertically arranged, and its bottom is connected to the lower clamping block. The top of the vertical plate 351 is connected to the discharge plate 352. The discharge plate 352 extends in the oblique rear direction, and its front height is greater than its rear height.

[0062] The unloading block 35 can work with the pusher plate 4 and the clamping mechanism 3 to achieve automatic unloading and complete unloading automation.

[0063] After the pipe 7 on the material holding trough 41 behind the pusher plate 4 is chamfered, the clamping mechanism 3 that clamps the pipe 7 opens, and the pipe 7 moves downward with the lower clamping block 32, sending the pipe 7 back to the material holding trough 41 behind the pusher plate 4. The lower clamping block 32 continues to move downward. At this time, the unloading block 35 installed on the lower clamping block 32 moves downward, so that the front height of the unloading block 35 is lower than the height of the material holding trough 41, which makes it convenient for the pusher plate 4 to continue to move backward. Then, the pipe 7 on the front receiving trough 41 of the pusher plate 4 enters above the lower clamping block 32. At this time, the pipe 7 on the rear receiving trough 41 of the pusher plate 4 is above the unloading block 35. Subsequently, the clamping mechanism 3 starts to work, the lower clamping block 32 begins to move upward, and the unloading block 35 moves upward accordingly, knocking the pipe 7 on the rear receiving trough 41 of the pusher plate 4 down. The pipe 7 rolls down along the extension direction of the unloading plate 352. The clamping mechanism 3 clamps the pipe 7 on the front receiving trough 41 of the pusher plate 4 and performs chamfering. After chamfering is completed, the above operation is repeated. After the two pipes 7 are unloaded, the pusher plate 4 returns to the initial position to prepare for loading. Multiple cycles of operation complete the fully automated unloading process. The clever cooperation of the unloading block 35, the pusher plate 4, and the clamping mechanism 3 improves the efficiency of chamfering and unloading.

[0064] like Figure 2As shown, in some specific embodiments, the chamfering machine 5 is provided with a chamfering drive device 52, which is connected to the chamfering machine 5 in a transmission manner. The chamfering machine 5 is slidably connected to the frame 1, and the chamfering drive device 52 can drive the chamfering machine 5 to move in the left and right directions.

[0065] The chamfering machine 5 can move left and right to adapt to chamfering pipes 7 of different lengths, meeting the chamfering requirements of pipes 7 of different specifications.

[0066] A second guide rail 11 is mounted on the frame 1. The second slider 12 on the chamfering machine 5 is slidably connected to the second guide rail 11. The chamfering drive device 52 is used to drive the chamfering machine 5 to move left and right. Taking the right chamfering machine 5 as an example, when the pipe 7 is being fed, it can move to the right to leave space, and then move to the left to chamfer the pipe 7, making the chamfering work more flexible and improving its versatility.

[0067] like Figure 2-5 As shown in some specific embodiments, the inner side of the baffle 21 is provided with two limiting plates 22, which extend in the vertical direction and are respectively provided on the front and rear sides of the baffle 21.

[0068] The installation of the limiting plate 22 can precisely limit the position of the pipe 7 and improve the stability of the equipment.

[0069] A certain space is formed between the front and rear limiting plates 22 on the baffle 21. The pipe 7 is placed between the positioning frame 2. The space between the limiting plates 22 restricts the position of the pipe 7, so that the pipe 7 is arranged vertically and can only move downward into the pusher plate 4 by gravity, thus stabilizing the pipe 7.

[0070] like Figure 6 As shown, in some specific embodiments, the automatic unloading chamfering device 65 and the cutting device 61 are connected by a conveyor belt 62, so that the pipe 7 cut by the cutting device 61 can be fed into the automatic unloading chamfering device 65. The automatic unloading chamfering device 65 and the cutting device 61 form a set of process machine tools 6.

[0071] The chamfering device 65 with automatic unloading is connected to the cutting device 61 via the conveyor belt 62 to form a complete automated production process. The pipe 7 can be automatically transferred from the cutting device 61 to the chamfering device 65 without manual intervention, which improves production efficiency and realizes automated continuous production.

[0072] like Figure 6 As shown, in some specific embodiments, the frame 1 is divided into a fixed frame 63 and a movable frame 64, and the movable frame 64 is slidably connected to the process machine tool 6.

[0073] The flexible movement of the mobile frame 64 facilitates chamfering operations on pipes 7 of different lengths.

[0074] The frame 1 on the right is a movable frame 64. The third slider 13 on the movable frame 64 is slidably connected to the third guide rail 14 on the process machine tool 6. The right side of the movable frame 64 is connected to a turntable 15 for transmission. By rotating the turntable 15 on the right side, the movable frame 64 is driven to move left and right. The movement of the frame 1 can make the positioning frame 2 expand or shrink, which is convenient for chamfering pipes 7 of different lengths.

[0075] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
