Description

Technical Field

[0001] The present invention relates to the field of aluminum wire processing, in particular to a segment cutting device for aluminum wire processing. Background Art

[0002] Aluminum wire refers to a metal wire material with uniform cross-section along its entire longitudinal length, made of pure aluminum or aluminum alloy as raw materials, processed by pressure along the center and delivered in coils. The cross-sectional shapes include circle, oval, square, rectangle, equilateral triangle and regular polygon. According to the material, it is divided into pure aluminum wire and alloy aluminum wire, and according to the purpose, it is divided into industrial aluminum wire and process aluminum wire. At present, there are still shortcomings in the existing aluminum wire reels. Most of the existing aluminum wire reels lack aluminum wire cutting mechanisms. When connecting the aluminum wire, external tools are needed to cut the aluminum wire. When the operator does not have cutting tools around to cut the aluminum wire, he needs to wait, which reduces the efficiency of aluminum wire connection and reduces the use effect of the aluminum wire reel.

[0003] In order to solve the above problems, after searching, a Chinese patent with announcement number CN214243308U discloses an aluminum wire reel with a cutting mechanism, which includes a reel body and side panels, both sides of the vertical end of the reel body are engaged with the inner surface wall of the vertical end of the side panel, and also includes: a cross bar, the cross bar is slidably connected to the inner surface wall of the vertical end of the side panel through sliders fixedly connected at both sides of the vertical end, the front end surface of the cross bar is provided with a through hole, the upper surface of the cross bar is fixedly connected to a telescopic rod, the side of the telescopic rod away from the cross bar is fixedly connected to a pressure plate, the bottom of the pressure plate is fixedly connected to a cutter, the side panels and the front end surfaces of the sliders are both provided with positioning holes, the upper surfaces of the two groups of side panels are fixedly connected to connecting belts, one side of the connecting belt is fixedly connected to a positioning rod, and the positioning rod is plugged into the positioning hole;

[0004] Although the above device can press the pressure plate cutter to cut the aluminum wire, the telescopic rod will restore the cutter to its original position after cutting. When the aluminum wire is reduced, the positioning rod will be pulled out, and the cross bar will be moved down to fix the aluminum wire. After fixing, the positioning rod will be plugged into the positioning hole. Since the positioning rod is fixed to the upper surface of the side plate by a connecting belt, it is convenient to use the positioning rod, thereby improving the connection efficiency of the aluminum wire and thus improving the use effect of the aluminum wire reel. However, in actual use, when the aluminum wire reel is cut by the cutter, when the two sets of telescopic rods push the cutter, if there are differences in the telescopic speed and stroke (such as mechanical tolerance, unstable power source pressure, etc.), the cutter will be unevenly stressed and the cutter may be skewed, resulting in an uneven cut surface of the aluminum wire (such as burrs, bevel cuts), and even deformation and damage of the cutter or telescopic rod due to excessive force on one side.

An "L"-shaped slot is provided at the end of the knife seat, and the "L"-shaped slot is screwed and fixed to the side wall of the guide seat. The outer side of the guide seat is fixedly connected to the segment cutting knife through the knife seat, and the segment cutting knife is driven to lift and lower by the guide seat to cut the aluminum wire body.

[0010] Furthermore, the bottom edge of the segment cutting knife is arranged opposite to the aluminum wire body, and the aluminum wire body is located between the limit seat and the connecting seat to form a segment cutting station.

[0018] 2. This solution secures the guide base to the segmenting knife via a knife holder on the outside of the guide base. The segmenting knife is driven up and down by the guide base to segment the aluminum wire. While the aluminum wire is being segmented, it can be fed by a stepping segmenting feeding mechanism. This allows the aluminum wire to be fed step by step while being segmented, thus achieving the purpose of equidistant segmentation of the aluminum wire. At the same time, the power source required for the stepping segmenting feeding mechanism to transport the aluminum wire and the power source for the segmenting knife to cut the aluminum wire are both stepping motors, eliminating the need to install two sets of motors, thereby reducing the overall manufacturing cost of the device.

[0019] 3. This solution uses the transmission of the primary and secondary pulleys, and the meshing connection between gears B and A, to achieve synchronous rotation of the upper and lower conveyor wheels in opposite directions. This transmission method ensures balanced clamping force between the two sets of conveyor wheels on the aluminum wire body. The friction-based step-by-step conveying is more stable and can precisely control the conveying length of the aluminum wire body, avoiding problems such as aluminum wire skew and slippage caused by asynchronous conveying. This provides a precise positioning basis for the subsequent cutting operation of the segmenting knife, improving overall processing accuracy.

[0020] 4. This solution adopts a transmission mode of a combination of a main pulley, a secondary pulley, gears A and gear B, which combines the buffering and vibration absorption characteristics of belt transmission with the high precision and high efficiency advantages of gear transmission; the pulley transmission can effectively reduce the impact during starting and braking, and protect the stepper motor and various transmission components; the gear engagement ensures the accuracy of power transmission, so that the rotation speed of the upper and lower conveying wheels is strictly matched with the output of the stepper motor, ensuring the consistency and reliability of the conveying action; the various components are integrated into an integral mechanism through a reasonable transmission relationship, and there is no need to reserve too much space for independent conveying motors and cutting motors, making the structure of the entire step-by-step cutting feeding mechanism more compact, which is conducive to installation in limited equipment space and improves the space utilization of the device.

[0030] Specific implementation method 1: Please refer to Figure 1-Figure 7The present invention provides a technical solution: a segment cutting device for aluminum wire processing, comprising a fixed frame 11, a base 5 is fixedly provided at the bottom of the fixed frame 11, a stepping segment cutting feeding mechanism 9 is installed at the bottom of the fixed frame 11, the bottom of the base 5 is fixed by four groups of supporting feet distributed at equal intervals, a guide rail 1 is fixedly provided on the surface of the base 5, a guide seat 4 is movably provided on the guide rail 1, a transmission arm 3 is movably installed on the surface of the guide seat 4, a knife seat 41 is fixedly provided on the side wall of the guide seat 4, a segment cutting knife 42 is installed on the outer side of the knife seat 41, an aluminum wire body 8 is provided at the bottom of the segment cutting knife 42, a limiting seat 6 is inserted through the outside of one side of the aluminum wire body 8, and a connecting seat 7 is inserted through the outside of the other side of the aluminum wire body 8, the connecting seat 7 and the limiting seat 6 are both fixedly connected to the base 5, and an accommodating opening arranged opposite to the segment cutting knife 42 is opened on the base 5.

[0031] Working principle: During actual use, the stepper motor 97 drives the guide seat 4 to perform linear lifting and lowering with the guide track 1 as the track through the rocker arm 2 and the transmission arm 3. The outer side of the guide seat 4 is fixedly connected to the segmenting knife 42 through the knife seat 41. The segmenting knife 42 is driven to lift and lower by the guide seat 4 to segment the aluminum wire body 8. While the aluminum wire body 8 is being segmented, it can be fed by the stepping segmenting feeding mechanism 9, so that the aluminum wire body 8 can be fed step by step while being segmented, and the purpose of equidistant segmentation of the aluminum wire body 8 can be achieved.

[0032] When the segment cutting knife 42 moves downward to cut the aluminum wire body 8, the two sides of the cut position on the aluminum wire body 8 are supported by the limit seat 6 and the connecting seat 7, so that the aluminum wire body 8 will not be offset when it is passively subjected to force, thereby ensuring the stability of the aluminum wire body 8 during cutting, ensuring that the cut surface of the aluminum wire is flat, and improving the cutting quality of the aluminum wire.

[0033] Specific embodiment 2: This embodiment is a further limitation of specific embodiment 1. The sizes of the guide rail 1 and the guide seat 4 are adapted to each other. The guide seat 4 is slidably arranged on the outside of the guide rail 1. The cross-section of the guide rail 1 is dovetail-shaped. The back of the guide rail 1 is fixedly arranged on the fixed frame 11. The back of the fixed frame 11 is fixedly mounted with a stepper motor 97.

[0034] A transmission arm 3 is movably mounted on the surface of the guide seat 4 via a pin shaft, and a rocker arm 2 is movably mounted on the end of the transmission arm 3 via a pin shaft. The end of the rocker arm 2 away from the transmission arm 3 is fixed to the output shaft of the stepper motor 97.

[0035] The stepper motor 97 drives the guide seat 4 to perform linear lifting and lowering with the guide track 1 as the track through the rocker arm 2 and the transmission arm 3. A positioning groove is provided on the knife seat 41 outside the guide seat 4, and a positioning bar is fixedly provided at the end of the segment cutting knife 42. The positioning bar is inserted into the inside of the positioning groove. At the same time, the length of the segment cutting knife 42 is greater than the height of the guide seat 4. An "L"-shaped slot is provided at the end of the knife seat 41. The "L"-shaped slot is screwed and fixed to the side wall of the guide seat 4. The outer side of the guide seat 4 is fixedly connected to the segment cutting knife 42 through the knife seat 41. The segment cutting knife 42 is driven to lift and lower by the guide seat 4 to cut the aluminum wire body 8.

[0036] like Figure 1 As shown: a positioning groove is provided on the knife seat 41 outside the guide seat 4, which is plugged into the positioning strip fixed at the end of the segment cutting knife 42. This structure can quickly realize the precise positioning of the segment cutting knife 42 and the knife seat 41, effectively avoiding offset during assembly, ensuring the coaxiality and verticality of the connection between the two, and laying the foundation for the stability of subsequent segment cutting work; at the same time, the length of the segment cutting knife 42 is greater than the height of the guide seat 4, ensuring that when the guide seat 4 drives it to rise and fall, the segment cutting knife 42 has enough travel to complete the segment cutting operation of the aluminum wire body 8, avoiding the problem of incomplete segment cutting due to insufficient length; the "L"-shaped slot at the end of the knife seat 41 is fixed to the side wall of the guide seat 4 by screw connection, and this connection The method not only achieves a firm combination of the knife holder 41 and the guide seat 4, but also facilitates installation and disassembly. When the knife holder 41 and the cutting knife 42 need to be replaced or repaired, the operating efficiency can be greatly improved, and the "L"-shaped structure increases the contact area, makes the connection force more uniform, and reduces the risk of loosening due to vibration in long-term use; and the guide seat 4 drives the cutting knife 42 to rise and fall through the knife holder 41 to perform cutting work. The entire transmission path is clear and direct, and the power transmission loss is small, which can make the cutting knife 42 respond more quickly, ensuring the timeliness and accuracy of cutting the aluminum wire body 8. The overall structural design is compact and reasonable, and the components are closely matched, which significantly improves the working reliability and cutting quality of the equipment.

[0037] The bottom edge of the segment cutting knife 42 is arranged opposite to the aluminum wire body 8. The aluminum wire body 8 is located between the limit seat 6 and the connecting seat 7 to form a segment cutting station. The aluminum wire body 8 is cut by the segment cutting knife 42 and is fed step by step by the step cutting feeding mechanism 9.

[0038] Specific embodiment three: This embodiment is a further limitation of specific embodiment one. The step-by-step cutting feeding mechanism 9 includes an upper conveying wheel 90, a support frame 901, a limiting wheel 902, a lower conveying wheel 91, gear A92, gear B93, a secondary pulley 94, a synchronous belt 95, a main pulley 96 and a stepping motor 97. The lower conveying wheel 91 is installed at the bottom of the upper conveying wheel 90, and the support frames 901 are movably provided on the rotating shafts of the lower conveying wheel 91 and the upper conveying wheel 90. The ends of the two groups of support frames 901 are movably installed with limiting wheels 902, and the two groups of limiting wheels 902 are respectively installed on the upper and lower sides of the aluminum wire body 8.

[0039] The upper conveying wheel 90 and the lower conveying wheel 91 are respectively installed on the upper and lower sides of the aluminum wire body 8. The upper conveying wheel 90 and the lower conveying wheel 91 move synchronously towards each other. Gears A92 and gears B93 are respectively installed on the ends of the rotating shafts of the upper conveying wheel 90 and the lower conveying wheel 91.

[0040] The sizes of gear A92 and gear B93 are adapted to each other, gear A92 and gear B93 are meshed and connected, a secondary pulley 94 is installed at the end of the rotating shaft of gear B93, a synchronous belt 95 is installed on the secondary pulley 94, and a main pulley 96 is installed on the side of the synchronous belt 95 away from the secondary pulley 94.

[0041] The main pulley 96 is fixedly connected to the output shaft of the stepper motor 97. The stepper motor 97 drives the gear B93 to rotate synchronously through the main pulley 96, the synchronous belt 95 and the secondary pulley 94.

[0042] The upper and lower conveying wheels 90 and 91 are also bonded with rubber tubes that increase the friction between them and the aluminum wire. The rubber material itself has a high friction coefficient. Compared with the metal wheel surface, the rubber tube can greatly increase the friction between the upper and lower conveying wheels 90, 91 and the aluminum wire body 8; this allows the conveying wheels to effectively avoid slipping when driving the aluminum wire body 8, especially when the aluminum wire body 8 is thin in diameter or there is slight oil on the surface. It can still maintain a stable step-by-step conveying rhythm, further ensuring the accuracy of the feeding length, cooperating with the synchronization of the gear transmission, and improving the overall conveying reliability; the rubber tube has good elasticity. When the upper and lower conveying wheels 90 and 91 clamp the aluminum wire body 8, the rubber material can disperse the clamping force through slight deformation, avoiding scratches and indentations on the aluminum wire surface caused by direct contact with the metal wheel surface; for aluminum wire bodies 8 with an insulating layer on the surface or that need to maintain a smooth finish, this buffer protection can effectively maintain the original performance and appearance quality of the aluminum wire, reducing the defective rate caused by the conveying process;

[0043] Two groups of support frames 901 are arranged in parallel, and the two groups of support frames 901 are installed on the base 5 through the bracket. A wire drum 10 is provided on the upper left side of the base 5, and an aluminum wire body 8 is wound on the wire drum 10. An inflatable shaft is inserted in the middle of the wire drum 10, and the inflatable shaft is movably installed on the top of the fixed frame 11 through a bearing seat.

[0044] like Figure 1-5 As shown: the working mode of the stepping segment feeding mechanism 9 is as follows: the output shaft of the stepping motor 97 drives the main pulley 96 to rotate, the main pulley 96 drives the secondary pulley 94 to rotate through the secondary pulley 94, the secondary pulley 94 drives the lower conveying wheel 91 to rotate through the gear B93, and at the same time, the gear B93 drives the gear A92 to rotate. When the gear B93 and the gear A92 are meshed and connected, they respectively drive the upper conveying wheel 90 and the lower conveying wheel 91 to rotate synchronously, and the rotation directions of the upper conveying wheel 90 and the lower conveying wheel 91 are opposite. The friction between the two sets of conveying wheels and the aluminum wire body 8 is used to realize the stepping conveying of the aluminum wire body 8. At the same time, the power source required for the stepping segment feeding mechanism 9 to convey the aluminum wire body 8 and the power source for the segment cutting knife 42 to cut the aluminum wire body 8 are both the stepping motor 97. There is no need to install two sets of motors, thereby reducing the overall production cost of the device.

[0045] The stepper motor 97 drives the guide seat 4 to perform precise linear lifting along the guide rail 1 through the rocker arm 2 and the transmission arm 3. The knife seat 41 and the segment cutting knife 42 fixed on the outside of the guide seat 4 move synchronously, thereby efficiently performing the segment cutting action on the aluminum wire body 8; at the same time, the stepping segment cutting feeding mechanism 9 coordinates the operation to feed the material, realizing the synchronous stepping feeding of the aluminum wire body 8 during the segment cutting process, ensuring that the aluminum wire body 8 can be accurately and automatically segmented at equal distances; segment cutting and feeding are carried out synchronously, which improves efficiency; the stepper motor 97 provides precise angle and position The positioning control, combined with the stable linear motion of the guide seat 4 along the guide rail 1, ensures high precision in the cutting position and length. Through the precise drive of the stepper motor 97 and the coordinated cooperation of the stepping cutting and feeding mechanism 9, the aluminum wire body 8 can be automatically and reliably segmented into equal distances without the need for manual intervention in measurement or positioning. The guide seat 4 strictly rises and falls along the guide rail 1, ensuring the straightness and stability of the motion trajectory of the cutting knife 42, improving the cutting quality and equipment reliability. The synchronized cutting and feeding process eliminates waiting time and significantly improves the overall processing efficiency.

[0046] In the step-by-step cutting feeding mechanism 9, the stepper motor 97 provides power for the conveying of the aluminum wire body 8 and the cutting action of the segment cutting knife 42 at the same time, without the need to install two additional motors; this design directly reduces the purchase cost of the motor, and at the same time simplifies the circuit connection and overall structure of the device, reduces the difficulty of assembly and the complexity of subsequent maintenance, and effectively controls the full cycle cost from production to use; through the transmission of the main pulley 96 and the secondary pulley 94, and the meshing connection of the gear B93 and the gear A92, the upper conveying wheel 90 and the lower conveying wheel 91 achieve synchronous rotation, and the rotation direction is opposite; this transmission method ensures that the clamping force of the two sets of conveying wheels on the aluminum wire body 8 is balanced, and the step-by-step conveying using friction is more stable, and can accurately control the conveying length of the aluminum wire body 8, avoiding the problems of aluminum wire skewness and slippage caused by asynchronous conveying, and providing a basis for the subsequent segment cutting knife. The cutting work of 42 provides an accurate positioning basis and improves the overall processing accuracy; the transmission method of the main pulley 96, the secondary pulley 94 and the gear A92 and the gear B93 is adopted, which has the buffering and vibration absorption characteristics of the belt drive and the high precision and high efficiency advantages of the gear drive; the pulley drive can effectively reduce the impact during starting and braking, and protect the stepper motor 97 and various transmission components; the gear engagement ensures the accuracy of power transmission, so that the rotation speed of the upper conveying wheel 90 and the lower conveying wheel 91 is strictly matched with the output of the stepper motor 97, ensuring the consistency and reliability of the conveying action; the various components are integrated into an integral mechanism through a reasonable transmission relationship, and there is no need to reserve too much space for independent conveying motors and cutting motors, making the structure of the entire stepping cutting feeding mechanism 9 more compact, which is conducive to installation in a limited equipment space and improves the space utilization of the device.
