Description

Technical Field

[0001] This utility model relates to a tube cutting and chamfering device for a PV tube. Background Technology

[0002] In the current "bulk tube cutting and chamfering" process, the tube fittings are cut by saw blade and fall into the material box. The chips are removed by manual air blowing and then manually transported into the chamfering machine. The chamfering machine then performs internal and external chamfering on the short tubes, which fall into the material box again, and are then manually blown to remove chips and manually transported.

[0003] The processing of the tube fittings during the production and processing of the PV tube is closely related to the tube fittings processing process, including but not limited to (clamping, cutting, transferring, distributing, inspection, blowing, chamfering, etc.). Therefore, the tube fittings need to be frequently transferred and moved back and forth, and a lot of manpower is required to move the workpieces for processing.

[0004] Currently, when the applicant is cutting X-ray tubes, a production line is typically equipped with one tube cutting machine and two chamfering machines. The tube cutting machine is used to cut the X-ray tubes. The short tubes cut by the tube cutting machine are manually transported to the two chamfering machines for chamfering. After chamfering, the short tubes fall into the material basket, which is then manually transported to a designated area for temporary storage. Throughout the entire production process, workers are also required to blow air to remove chips at necessary locations. The entire process involves a lot of manual operation, which not only requires a large number of workers, but also results in high labor intensity for the workers, which is not conducive to improving production efficiency. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a tube cutting and chamfering device for X-ray tubes, which effectively solves the problems mentioned in the background art.

[0006] The technical solution adopted in this utility model is:

[0007] A tube cutting and chamfering device for X-ray tubes includes a tube cutting machine and two chamfering machines arranged side by side at the discharge end of the tube cutting machine, as well as a material distribution and conveying mechanism arranged between the tube cutting machine and the chamfering machine. The material distribution and conveying mechanism includes a first lifting mechanism arranged along the discharge direction of the tube cutting machine at the discharge port of the tube cutting machine, a second lifting mechanism arranged side by side with the first lifting mechanism, a first transfer mechanism for transferring short tubes cut by the tube cutting machine to the first lifting mechanism, a second transfer mechanism for transferring short tubes held by the first transfer mechanism to the second lifting mechanism, and a conveying mechanism for conveying the short tubes at the discharge ends of the first lifting mechanism and the second lifting mechanism to the corresponding chamfering machines.

[0008] Preferably, the conveying mechanism includes a single-tube conveying mechanism, a feeding guide mechanism, and a chamfering transfer mechanism that feeds the short tube into the chamfering machine station, which are connected in sequence. The discharge end of the single-tube conveying mechanism is provided with an ejection mechanism that pushes the short tube into the feeding guide mechanism.

[0009] Preferably, the feeding guide mechanism includes a guide slope and guide baffles symmetrically arranged on both sides of the bottom end of the guide slope. A guide groove is provided on the inner side of the guide baffle. The top end of the guide groove is connected to the guide slope, and the bottom end is closed to form a short pipe temporary storage area. The chamfering and transplanting mechanism sends the short pipe from the short pipe temporary storage area into the chamfering machine station.

[0010] Preferably, the chamfering transplanting mechanism includes a pair of symmetrically arranged grippers and a pair of cylinders that drive the grippers to move.

[0011] Preferably, the first transfer mechanism includes a first moving platform that moves linearly along the discharge direction of the pipe cutter, and a rotating mechanism disposed on the first moving platform. The fixed seat of the rotating mechanism is fixed on the first moving platform, and a first clamping mechanism is fixedly installed on the rotating part. The second transfer mechanism includes a second moving platform that moves linearly between the first lifting mechanism and the second lifting mechanism, and a second clamping mechanism fixedly installed on the second moving platform.

[0012] Preferably, the second transplanting mechanism has a baffle on the other side relative to the first lifting mechanism, and the baffle is fixed to the second lifting mechanism.

[0013] Preferably, the discharge end of the tube cutting machine is provided with a first air blowing mechanism, which is used to blow air to remove chips from the entire bundle of tubes.

[0014] Preferably, the first lifting mechanism and the second lifting mechanism are provided with a second air blowing mechanism on their sides, which is used to blow air to remove chips from the inner cavity of a single short pipe.

[0015] Preferably, the bottom of the chamfering machine is provided with a discharge mechanism, and the discharge mechanism is provided with a third air blowing mechanism, which is used to blow air to remove chips from the chamfered short pipe.

[0016] Preferably, a material basket is placed at the discharge end of the discharge mechanism.

[0017] The innovative points of this utility model are as follows:

[0018] 1. Material conveying structure with "double lifting + double transfer":

[0019] An innovative first lifting mechanism and a second lifting mechanism (arranged side by side) are set up between the discharge end of the pipe cutting machine and the two chamfering machines side by side.

[0020] It is equipped with a first transfer mechanism (responsible for taking material from the pipe cutting machine and transferring it to the first lifting mechanism) and a second transfer mechanism (responsible for taking material from the first transfer mechanism and transferring it to the second lifting mechanism).

[0021] This architecture ingeniously enables the automatic and efficient distribution of short pipes produced by a single pipe cutting machine to two chamfering machines, solving the problems of matching the cycle time and load balancing of the pipe cutting and chamfering processes, and is the foundation for the automation of the entire device;

[0022] 2. Integrated conveying path and positioning mechanism:

[0023] A dedicated conveying path was designed for each chamfering machine, including: a single-tube conveying mechanism, an ejection mechanism, a feeding guide mechanism, and a chamfering transfer mechanism;

[0024] Ejection mechanism: Precisely pushes the short tube on the single-tube conveying mechanism into the next stage;

[0025] Feeding guiding mechanism: The core of it is that it includes a guide slope and a guide baffle with a guide groove. The guide slope causes the short pipe to roll into the guide groove, and the closed temporary storage area at the bottom of the guide groove reliably positions the short pipe, providing a precise gripping position for subsequent transplanting, and ensuring the accuracy and stability of the chamfering machine's feeding.

[0026] 3. Optimized transplanting mechanism design:

[0027] The first transplanting mechanism not only achieves linear movement but also integrates a rotating mechanism, enabling the first clamping mechanism on it to rotate. After the short pipe is discharged, it completes a 90° rotation, making it easy to place into the first lifting mechanism and the second lifting mechanism.

[0028] Second transplanting mechanism: Since the second transplanting mechanism directly receives and transplants materials from the first transplanting mechanism, there is no need to rotate the short pipe, eliminating the need for a rotating mechanism and simplifying the material distribution and conveying mechanism. A baffle is installed on the side of the second lifting mechanism to ensure the stability of the short pipe during the transplanting process and prevent it from slipping or shifting.

[0029] Chamfering and transplanting mechanism: It adopts symmetrical grippers and is driven by a pair of cylinders to ensure stable and reliable clamping. It can accurately send the short pipes in the temporary storage area into the chamfering machine station. The two actions of transplanting and clamping are realized by a pair of cylinders. The structure is simple and reasonable.

[0030] 4. Multi-stage, automated, and integrated air-blowing chip removal system:

[0031] First air blowing mechanism: Located at the discharge end of the tube cutter, it performs preliminary air blowing to remove chips from the entire bundle of tubes, removing most of the chips at the source;

[0032] The second air blowing mechanism is located on the side of the first and second lifting mechanisms. It blows air into the inner cavity of a single short pipe to remove chips. This step is completed automatically during the material distribution process, replacing manual air blowing.

[0033] The third air blowing mechanism is located on the discharge mechanism at the bottom of the chamfering machine. It performs final air blowing to remove chips from the short tube after chamfering and is also integrated into the discharge process.

[0034] This design fully automates the air blowing process and integrates it into key nodes of material flow, covering the main stages of chip generation (cutting, chamfering) and key locations (whole bundle, single tube inner cavity, finished product).

[0035] 5. Automated material unloading and temporary storage:

[0036] The bottom of the chamfering machine is equipped with a discharge mechanism. The finished short tubes that have been chamfered are automatically output through this mechanism, and air blowing is completed to remove chips during the output process.

[0037] The material basket is placed directly at the discharge end of the discharge mechanism, and the finished short pipes automatically fall into the material basket for temporary storage, completely eliminating the need for manual handling of the short pipes to the material basket.

[0038] The beneficial effects of this utility model are as follows:

[0039] 1. Significantly reduce manual operations and lower labor costs:

[0040] Eliminating handling: Completely eliminates the two critical manual handling steps of short pipes from the pipe cutting machine to the chamfering machine, and then from the chamfered short pipes to the material basket;

[0041] Eliminates manual air blowing: Completely replaces the manual air blowing chip removal operation required after pipe cutting and chamfering in the original process;

[0042] Reduced manual intervention: The entire process (cutting, chip removal, diversion, conveying, positioning, chamfering, further chip removal, and temporary storage) is highly automated, significantly reducing the number of operators required;

[0043] 2. Significantly improves production efficiency:

[0044] Continuous automation: Seamless connection between each process, smooth material flow, and elimination of waiting time caused by manual handling and operation;

[0045] Parallel processing: Through the material distribution mechanism, the output of one pipe cutting machine can be supplied to two chamfering machines for processing at the same time, which improves equipment utilization and overall production line cycle time;

[0046] Reduce non-processing time: Automated handling and chip removal are faster and more consistent than manual processes, shortening the overall processing cycle of a single product;

[0047] 3. Improve processing quality and consistency:

[0048] Reduced impact damage: Automated transplanting and conveying reduce the risk of short pipes being bumped or scratched during manual handling;

[0049] Precise positioning: The guide groove and temporary storage area design of the feeding guide mechanism, together with the transfer mechanism, ensures that the short pipe can be accurately and stably fed into the chamfering machine station, which helps to ensure the consistency of chamfering quality;

[0050] More thorough chip removal: Multi-stage, automated air blowing systems (especially for single-tube cavities) are more reliable and thorough than manual air blowing, reducing product quality issues or subsequent process problems caused by chip residue;

[0051] 4. Improve the working environment and safety:

[0052] Reduce labor intensity: Workers are freed from heavy, repetitive tasks such as carrying and blowing air;

[0053] Reduced safety hazards: Reduced opportunities for workers to directly operate equipment (especially near pipe cutting and chamfering stations) and frequently come into contact with workpieces, thus reducing the risk of workplace injuries;

[0054] Improving the environment: Centralized, automated air blowing may be easier to integrate with dust removal equipment, thus improving the workshop environment;

[0055] 5. Optimize production processes and space utilization:

[0056] Process integration: The previously separate pipe cutting and chamfering processes (including intermediate chip removal and handling) are integrated into a compact automated production line;

[0057] Compact structure: The device design (pipe cutting machine, material conveying mechanism, and chamfering machine side by side) is reasonable and has a high space utilization rate.

[0058] This utility model achieves a high degree of automation in the entire process of the tube from cutting to chamfering, chip removal, and discharge through a carefully designed "double lifting + double transfer" material distribution architecture, an integrated conveying and positioning path (especially the feeding guide mechanism with a temporary storage area), an optimized transfer mechanism, and a multi-stage automated air blowing system. Its technical effects are mainly reflected in significantly reducing reliance on manual labor, significantly improving production efficiency, steadily improving product quality, and improving the working environment and safety. It effectively solves the pain points mentioned in the background technology, such as the high manual operation, high labor intensity, and low efficiency of traditional processing methods.

[0073] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0074] like Figure 1-8 As shown, a tube cutting and chamfering device for X-ray tubes includes a tube cutting machine 1 and two chamfering machines 2 arranged side by side at the discharge end of the tube cutting machine 1, as well as a material distribution and conveying mechanism arranged between the tube cutting machine 1 and the chamfering machines 2. The material distribution and conveying mechanism includes a first lifting mechanism 3 arranged along the discharge direction of the tube cutting machine 1 at the discharge port of the tube cutting machine 1, a second lifting mechanism 4 arranged side by side with the first lifting mechanism 3, a first transfer mechanism 5 for transferring the short tubes cut by the tube cutting machine 1 to the first lifting mechanism 3, a second transfer mechanism 6 for transferring the short tubes held by the first transfer mechanism 5 to the second lifting mechanism 4, and a conveying mechanism 7 for conveying the short tubes at the discharge ends of the first lifting mechanism 3 and the second lifting mechanism 4 to the corresponding chamfering machines 2.

[0075] The conveying mechanism 7 includes a single-tube conveying mechanism 71, a feeding guide mechanism 72, and a chamfering and transfer mechanism 73 that feeds the short tube into the chamfering machine 2 station, which are connected in sequence. The discharge end of the single-tube conveying mechanism 71 is provided with an ejection mechanism 74 that pushes the short tube into the feeding guide mechanism 72.

[0076] The feeding guide mechanism 72 includes a guide slope 721 and guide baffles 722 symmetrically arranged on both sides of the bottom end of the guide slope 721. A guide groove 723 is provided on the inner side of the guide baffle 722. The top end of the guide groove 723 is connected to the guide slope 721, and the bottom end is closed to form a short pipe temporary storage area 724. The chamfering and transplanting mechanism 73 sends the short pipe from the short pipe temporary storage area 724 into the chamfering machine 2 station.

[0077] The chamfered transplanting mechanism 73 includes a pair of symmetrically arranged grippers 731 and a pair of cylinders 732 that drive the grippers 731 to move.

[0078] The first transplanting mechanism 5 includes a first moving platform 51 that moves linearly along the discharge direction of the pipe cutter 1, and a rotating mechanism 52 disposed on the first moving platform 51. The fixed seat of the rotating mechanism 52 is fixed on the first moving platform 51, and a first clamping mechanism 53 is fixedly installed on the rotating part. The second transplanting mechanism 6 includes a second moving platform 61 that moves linearly between the first lifting mechanism 3 and the second lifting mechanism 4, and a second clamping mechanism 62 fixedly installed on the second moving platform 61.

[0079] The second transplanting mechanism 6 is provided with a baffle 63 on the other side relative to the first lifting mechanism 3, and the baffle 63 is fixed on the second lifting mechanism 4.

[0080] The tube cutting machine 1 is equipped with a first air blowing mechanism 8 at the discharge end, which is used to blow air to remove chips from the entire bundle of tubes.

[0081] The first lifting mechanism 3 and the second lifting mechanism 4 are provided with a second air blowing mechanism 9 on their sides. The second air blowing mechanism 9 is used to blow air to remove chips from the inner cavity of a single short pipe.

[0082] The bottom of the chamfering machine 2 is provided with a discharge mechanism 10, and the discharge mechanism 10 is provided with a third air blowing mechanism. The third air blowing mechanism is used to blow air to remove chips from the short tube after chamfering. The third air blowing mechanism only needs to be able to spray positive pressure gas onto the short tube on the discharge mechanism 10. Its specific setting position and method are not specifically limited, so it is not shown in the attached figure.

[0083] A material basket 11 is placed at the discharge end of the discharge mechanism 10.

[0084] The overall workflow of this utility model is as follows: pipe cutting → transplanting / rotation → material distribution and lifting → conveying / positioning → chamfering → chip removal / discharging. The entire process is automated and requires no manual handling or air blowing. Details are as follows:

[0085] 1. Pipe cutting and preliminary chip removal:

[0086] The first clamping mechanism 53 of the first transplanting mechanism 5 is a cutting station of the pipe cutting machine 1, which clamps the whole bundle of tubes on the station, and then the pipe cutting machine 1 cuts the long tubes into short tubes.

[0087] The first air blowing mechanism 8 is located at the discharge end of the pipe cutter 1 and blows air onto the bundle of cut short pipes to remove surface chips (source chip removal).

[0088] 2. Transplanting and Providing:

[0089] First transplanting mechanism 5: First moving platform 51 moves along the discharge direction of pipe cutter 1 and controls first clamping mechanism 53 to move the short pipe it clamps to directly above the inlet of first lifting mechanism 3;

[0090] Rotating mechanism 52: Rotates the short tube 90° (rotates in the horizontal plane) to facilitate placement into the lifting mechanism;

[0091] If the destination of the short pipe is the first lifting mechanism 3, the first clamping mechanism 53 can be released directly to allow the short pipe to fall into the first lifting mechanism. If the destination of the short pipe is the second lifting mechanism 4, the second moving platform 61 is controlled to move linearly to the first lifting mechanism 3, and the second clamping mechanism 62 is used to directly pick up the short pipe on the first clamping mechanism 53. Finally, the short pipe is transferred to the feeding point of the second lifting mechanism 4, and the second clamping mechanism 62 is released to allow the short pipe to fall into the second lifting mechanism 4.

[0092] Baffle 63: Fixed to the side of the second lifting mechanism 4 to prevent the short pipe from slipping when it is transferred from the first lifting mechanism 3 to the second lifting mechanism 4;

[0093] Innovation points:

[0094] The dual-lifting + dual-transfer architecture enables automatic material distribution from one pipe cutting machine to two chamfering machines;

[0095] The first transplanting mechanism integrates a rotation function, while the second transplanting mechanism has a simplified design (no rotation).

[0096] 3. Single-pipe chip removal and conveying:

[0097] Second air blowing mechanism 9: Located on the side of the lifting mechanism, it blows air into the inner cavity of a single short pipe to remove residual chips inside the pipe (replacing manual labor).

[0098] Conveying mechanism 7: (One set for each chamfering machine):

[0099] Single-pipe conveying mechanism 71: receives the short pipe from the lifting mechanism;

[0100] Ejection mechanism 74: pushes the short tube into the feed guide mechanism 72;

[0101] Feeding guide mechanism 72: The short pipe rolls down along the guide slope 721 and slides into the short pipe temporary storage area 724 at the bottom through the guide groove 723 (located inside the guide baffle 722) to achieve precise positioning;

[0102] Innovation points:

[0103] The guide groove and short pipe storage area design ensures the stability of the short pipe position and provides a precise gripping point for chamfered transplanting.

[0104] 4. Chamfering and feeding:

[0105] Chamfered transplanting mechanism 73: A pair of cylinders 732 drive symmetrical grippers 731 to grip the short tube from the short tube storage area 724;

[0106] The short tube is precisely transferred to station 2 of the chamfering machine for internal and external chamfering;

[0107] Innovation points:

[0108] The chamfering and transplanting mechanism 73, through the setting and proper control of only a pair of cylinders 732, not only realizes the transplanting of short pipes, but also uses the grippers 731 to hold and position the short pipes during chamfering. The specific control method of the chamfering and transplanting mechanism 73 is as follows: The chamfering station of the chamfering machine 2 is on the same horizontal plane as the short pipe temporary storage area 724. During the transplanting operation, firstly, the grippers near the short pipe temporary storage area 724 are controlled to move towards the short pipe temporary storage area 724 until they pass over the short pipe temporary storage area 724. Then, the ejection mechanism 74 is controlled to eject a short pipe. Pushing in the feeding guide mechanism 72 causes the short tube to slide from the guide slope 721 into the guide groove 723 and finally fall into the short tube storage area 724. At this time, the grippers 731 on both sides of the short tube storage area 724 are controlled to move into the short tube in the short tube storage area 724 until the short tube is clamped. Finally, by controlling the two cylinders 732, the short tube is moved to the chamfering station of the chamfering machine 2. At this time, the chamfering operation can be performed. After the chamfering operation is completed, the grippers 731 are released so that the chamfered short tube can fall into the discharge mechanism 10 for discharge.

[0109] 5. Chamfering, chip removal, and unloading:

[0110] Chamfering machine 2: Completes the internal and external chamfering of short pipes;

[0111] Discharge mechanism 10: Automatic output of the chamfered short tube;

[0112] The third air blowing mechanism is integrated into the discharge mechanism and blows air onto the finished product short tube to remove the chips generated during chamfering.

[0113] Material basket 11: Placed at the discharge end, the finished short tubes automatically fall into the basket for temporary storage.

[0114] In this utility model, production can be achieved by specifically equipping the following personnel:

[0115] 1. One worker is assigned to the pipe cutting machine to perform the feeding operation;

[0116] 2. Each material discharge mechanism shall have a worker stationed at the material basket at the discharge port to replace the material basket when it is full of short pipes.

[0117] Therefore, it can be seen that this utility model only requires 3 workers to carry out production operations, and the workers' labor intensity is low, which is conducive to improving production efficiency and achieving safe production.

[0118] Since the following structures (first lifting mechanism, second lifting mechanism, ejection mechanism, rotation mechanism, first clamping mechanism, second clamping mechanism, first blowing mechanism, second blowing mechanism, third blowing mechanism and discharge mechanism) are commonly used structures in this field, this utility model does not describe them in detail. For example, the first lifting mechanism, second lifting mechanism and discharge mechanism can adopt a secondary lifting mechanism for a ball tube disclosed in Chinese Patent No. CN2024214871492, the ejection mechanism can be realized by an ejection cylinder, the rotation mechanism can be realized by a rotation cylinder, and the first blowing mechanism, second blowing mechanism and third blowing mechanism can be realized by nozzles capable of emitting air.

[0119] Finally, it should be noted that the above examples are merely specific embodiments of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. All variations that can be directly derived or conceived by those skilled in the art from the disclosure of this utility model should be considered within the protection scope of this utility model.
