Description

Technical Field

[0001] This utility model belongs to the field of aluminum cutting technology, and specifically relates to a slitting device for aluminum processing with a pre-pressing structure. Background Technology

[0002] In modern industrial production, aluminum is widely used in aerospace, building decoration, electronic equipment and many other fields due to its excellent properties such as light weight, high strength and corrosion resistance. In the aluminum processing process, slitting is an extremely critical process, and its processing quality directly determines the performance and quality of the subsequent aluminum products.

[0003] Currently, the aluminum slitting equipment commonly found on the market has significant technical shortcomings. The most prominent one is the general lack of a pre-compression structure. During the slitting operation, due to the lack of a pre-compression step, the aluminum material faces many problems at the moment of cutting. First, the cutting force will directly act on the aluminum material, making it very easy to shift and shake. For slitting tasks with high precision requirements, even the slightest positional deviation can cause the product size accuracy to deviate significantly from the standard, resulting in a large number of scraps and greatly increasing production costs.

[0004] Secondly, aluminum materials can deform due to uneven stress during the cutting process, especially thin-walled and complex-shaped aluminum materials. The impact of the cutting force causes an imbalance of internal stress in the material, resulting in bending, twisting and other deformation phenomena, which seriously affect the appearance and internal quality of the aluminum material. Moreover, the lack of a pre-compression structure makes it impossible for the aluminum material to effectively buffer vibration during cutting. The vibration generated during the cutting process not only reduces the flatness of the cut surface, resulting in a rough surface and ripples, but may also leave scratches and burrs on the surface of the aluminum material. It can be seen that the existing technology has certain defects and shortcomings, so it is necessary to improve its design. Utility Model Content

[0012] As a preferred technical solution, the cutting assembly includes a fixing plate, which is fixedly installed on one side of the slider. A second electric push rod is fixedly installed on the top of the fixing plate. The output end of the second electric push rod passes through the fixing plate and is fixedly connected to a bending arm. The outer end of the bending arm is fixedly connected to a housing. A cutting disc is rotatably connected inside the housing. A fourth motor is fixedly connected to the middle of the outer side of the housing.

[0016] First, this device, with its pre-pressing and positioning mechanism, effectively improves the aluminum cutting performance. When the device is activated, the aluminum material is precisely positioned on top of the guide roller. The first electric push rod applies stable force, pushing the mounting base and pressure roller downwards to firmly press the aluminum material between the pressure roller and the guide roller. Then, the second motor is started, and through the precision transmission of the worm gear, it drives the pressure roller to rotate, allowing the aluminum material to move smoothly between the two rollers. During cutting, the first electric push rod continuously applies pressure and positions the material to ensure its stability. The second motor flexibly adjusts the transverse and longitudinal displacement of the aluminum material and can also drive the guide roller and pressure roller to reciprocate and press the aluminum material before and after cutting. This not only ensures the stability and quality of the cutting but also enables automatic feeding, greatly improving the ease of use and efficiency of the device.

[0017] Secondly, this device optimizes the aluminum cutting process by coordinating the waste collection component with the cutting mechanism. During aluminum cutting, the second electric push rod precisely controls the bending arm and the housing to descend, bringing the cutting disc closer to the aluminum. The fourth motor drives the cutting disc to rotate at high speed for precise cutting of the aluminum. Simultaneously, the third motor drives the lead screw to cause the slider and cutting disc to move laterally, achieving linear cutting. Cutting debris falls into the side rail collection frame through the reserved groove. During cleaning, the mounting screw can be rotated, and the collection frame and slide plate can be quickly disassembled. This design achieves automated cutting and debris collection and cleaning. Combined with the pre-pressure positioning mechanism, it achieves continuous automated cutting, improving cutting convenience and processing efficiency. Attached Figure Description

[0024] Example

[0025] refer to Figures 1 to 5 This embodiment of an aluminum material processing slitting device with a pre-pressing structure includes a base 1, with support legs 2 fixedly installed at the four corners of the top of the base 1, a processing table 3 fixedly installed on the top of the support legs 2, pre-pressing positioning mechanisms 5 fixedly installed on both sides of the top of the processing table 3, a cutting mechanism 6 fixedly installed in the middle of the top of the processing table 3, a cutting reserved groove 4 opened in the middle of the top of the processing table 3, and a waste collection component 7 provided at the bottom of the processing table 3 at the position of the cutting reserved groove 4.

[0026] The pre-pressure positioning mechanism 5 includes a concave seat 51, which is fixedly installed on both sides of the top of the processing table 3. Guide rollers 52 are rotatably connected at equal intervals inside the concave seat 51. A fixed arm 53 is fixedly installed on the outer side of the concave seat 51. A first electric push rod 54 is fixedly installed on the top of the fixed arm 53. The output end of the first electric push rod 54 passes through the fixed arm 53 and is fixedly installed with a pre-pressure drive assembly 55. The base 1 of this slitting device stably supports the processing table 3 through support legs 2 at the four corners of the top. When the pre-pressure positioning mechanism 5 is working, the concave seats 51 located on both sides of the top of the processing table 3 provide a mounting base. The concave seats 51 are rotatably connected at equal intervals inside. The guide roller 52, which is rotatably connected at intervals, is used to place aluminum material. When the aluminum material needs to be pre-pressed and positioned, the first electric push rod 54, which is fixedly installed on the top of the fixed arm 53 on the outside of the concave seat 51, is activated. Its output end, with a stable and controllable driving force, pushes the pre-press drive assembly 55 downward through the fixed arm 53. During the downward movement of the pre-press drive assembly 55, it cooperates with the guide roller 52 to tightly press and fix the aluminum material placed on the guide roller 52, laying the foundation for the stable positioning of the aluminum material in the subsequent cutting process, ensuring the accuracy of the cutting operation, avoiding cutting deviations caused by displacement, shaking, etc. during the processing of the aluminum material, and ensuring processing quality.

[0027] refer to Figures 1-3The preload drive assembly 55 includes a mounting base 551, which is fixedly mounted on the bottom output end of the first electric push rod 54. Pressure rollers 552 are rotatably connected at equal intervals on the inner side of the mounting base 551. A power unit 553 is provided on one side of the mounting base 551. The power unit 553 includes a side plate 5531 and worm gears 5532. The side plate 5531 is fixedly mounted on both ends of one side of the concave seat 51. The worm gears 5532 are rotatably connected to one side of the mounting base 551 in a linear arrangement at equal intervals. The inner side of the side plate 5531 is connected to one end of the pressure roller 552. A worm gear 5533 is rotatably connected between the inner sides of the side plate 5531. The worm gear 5533 and the worm wheel 5532 are connected in a transmission connection. A second motor 5534 is fixedly connected to the outer side of one side plate 5531. The output end of the second motor 5534 is connected to one end of the worm gear 5533. When the pre-pressure drive assembly 55 of this device is working, the bottom output end of the first electric push rod 54 pushes the mounting base 551 to move down. The inner sides of the mounting base 551 are rotatably connected at equal intervals. The pressure roller 552 descends accordingly, cooperating with the guide roller 52 to tightly press the aluminum material together. At this time, the second motor 5534 is started, and its output end drives the worm gear 5533 connected to it to rotate. Since the worm gear 5533 is connected to the worm wheels 5532 arranged linearly at equal intervals on one side of the mounting base 551, and the inner side of the worm wheels 5532 is connected to one end of the pressure roller 552, the rotation of the worm gear 5533 will drive the worm wheels 5532 to rotate synchronously, thereby driving all the pressure rollers 552 to rotate. After the pressure rollers 552 rotate, they can effectively... The aluminum material being pressed is driven to move smoothly between the guide roller 52 and the pressure roller 552, and continuous pressure is applied by the first electric push rod 54. Combined with the mutual pressing of the pressure roller 552 and the guide roller 52, it can not only play a role in precise positioning during the aluminum material cutting process and ensure the stability of the aluminum material, but also flexibly adjust the lateral and longitudinal displacement of the aluminum material between the guide roller 52 and the pressure roller 552 by controlling the second motor 5534, so as to realize the rolling operation of the aluminum material, improve the stability and quality of the slitting process, and realize the automatic feeding function.

[0028] refer to Figures 1-3 and Figure 5The cutting mechanism 6 includes a frame 61, which is fixedly installed at the top center of the processing table 3. A top rail 62 is fixedly installed on the top of the frame 61. A lead screw 63 is rotatably connected inside the top rail 62. A slider 64 is threadedly connected to the outer surface of the lead screw 63. The slider 64 is slidably connected inside the top rail 62. A cutting assembly 66 is fixedly installed on one side of the slider 64. A third motor 65 is fixedly connected to one end of the top rail 62. The output end of the second motor 5534 is fixedly connected to one end of the lead screw 63. The cutting assembly 66 includes a fixing plate 661. The fixing plate 661 is fixed... Mounted on one side of slider 64, a second electric push rod 662 is fixedly mounted on the top of fixed plate 661. The output end of the second electric push rod 662 passes through fixed plate 661 and is fixedly connected to bending arm 663. The outer end of bending arm 663 is fixedly connected to housing 664. Cutting disc 665 is rotatably connected inside housing 664. A fourth motor 666 is fixedly connected to the middle of the outer side of housing 664. The output end of fourth motor 666 is fixedly connected to cutting disc 665. When the cutting mechanism 6 of this device is working, the frame 61 mounted on the middle of the top of processing table 3 is a whole. The cutting mechanism 6 provides stable support. The third motor 65 at one end of the top rail 62 is activated, and its output end drives the lead screw 63 to rotate. Since the lead screw 63 is threadedly connected to the slider 64, and the slider 64 can slide inside the top rail 62, the rotation of the lead screw 63 drives the slider 64 to slide smoothly inside the top rail 62. The fixing plate 661 fixed on one side of the slider 64 moves laterally, thereby driving the entire cutting assembly 66 to move. When aluminum cutting is required, the second electric push rod 662 at the top of the fixing plate 661 is activated, and its output end passes through the fixing plate 661 to push the bending arm 663 downward. As the bending arm 663 moves, the housing 664 connected to its outer end also descends synchronously, causing the cutting disc 665 inside the housing 664 to gradually approach the aluminum material. At this time, the fourth motor 666 in the middle of the outer side of the housing 664 starts operating, and its output end drives the cutting disc 665 to rotate at high speed. The high-speed rotating cutting disc 665 contacts the aluminum material, which can perform stable and precise cutting processing on the aluminum material. The third motor 65 drives the lead screw 63 to rotate, realizing the lateral displacement of the cutting component 66, thereby controlling the cutting disc 665 to perform linear cutting on the aluminum material to meet different cutting needs.

[0029] refer to Figures 1-3The waste collection assembly 7 includes side rails 71, which are fixedly connected to the bottom of the top base and located on both sides of the cutting pre-reserved groove 4. A sliding plate 72 is slidably connected inside the side rails 71, and a collection frame 73 is fixedly installed on the inner side of the sliding plate 72. The collection frame 73 is located directly below the cutting pre-reserved groove 4. A connecting frame 74 is fixedly installed at the front end of the side rails 71, and a mounting screw 75 is threadedly connected to the middle of the connecting frame 74. The mounting screw 75 is a hand-tightening screw, and its end passes through the connecting frame 74 and the collection frame 73, threadedly connected. The side rails 71 of the waste collection assembly 7 are fixed to the bottom of the top base and located on both sides of the cutting pre-reserved groove 4, providing an installation foundation for the entire waste collection assembly 7. During aluminum cutting, the cutting debris generated falls directly below the cutting pre-reserved groove 4 through the guiding action of the groove. Inside the square collection frame 73, the collection frame 73 is installed inside the slide plate 72, which can slide flexibly inside the side rail 71. When it is necessary to clean the waste in the collection frame 73, the operator manually rotates the hand-tight mounting screw 75. The end of the mounting screw 75 passes through the connecting frame 74 and is threadedly connected to the collection frame 73. As the screw rotates, it gradually disengages from the collection frame 73. At this time, the slide plate 72 can be easily pulled out along the inside of the side rail 71, so that the collection frame 73 can be conveniently removed for waste cleaning. After cleaning, the operation is reversed, the slide plate 72 is pushed into the side rail 71, and the mounting screw 75 is tightened to fix the collection frame 73 in its original position, so as to continue to collect the debris generated by subsequent cutting, ensuring the cleanliness of the cutting working environment and improving the overall convenience of the slitting device operation.

[0030] Operating Principle and Advantages: This device, through the pre-pressing positioning mechanism 5, allows for precise placement of the aluminum material on top of the guide roller 52 upon initial use. Then, the first electric push rod 54 is activated. This electric push rod, with its stable and controllable driving force, pushes the mounting base 551 downwards. As the mounting base 551 moves downwards, the pressure rollers 552 connected to it descend synchronously, thus tightly pressing and fixing the aluminum material between the pressure rollers 552 and the guide roller 52. At this point, the second motor 5534 is activated. After the second motor 5534 starts operating, its output shaft drives the worm gear 5533 to rotate. Because the worm gear 5533 and the worm wheel 5532 are connected by a precise transmission method, as the worm gear 5533 continues to rotate, the worm wheel 5532 rotates synchronously. The rotation of the worm wheel 5532 further drives all the pressure rollers 552 inside the mounting base 551 to rotate. Through the rotational movement of the pressure rollers 552, the device effectively drives… The aluminum material moves smoothly between the guide roller 52 and the pressure roller 552. During this process, the first electric push rod 54 continuously applies pressure, which, together with the mutual pressing action of the guide roller 52 and the pressure roller 552, provides precise positioning during the aluminum material cutting process, ensuring a stable and reliable pressing and fixing effect and maintaining a stable position for the aluminum material during cutting. On the other hand, the operation of the second motor 5534 allows for flexible control of the reciprocating lateral and longitudinal displacement of the aluminum material between the guide roller 52 and the pressure roller 552. This design, combining the pressure application of the first electric push rod 54 with the drive of the second motor 5534, allows the guide roller 52 and the pressure roller 552 to work together before and after cutting, performing reciprocating rolling operations on the aluminum material. This not only significantly improves the stability and quality of the aluminum material slitting process but also achieves automatic feeding, greatly enhancing the convenience and efficiency of the device.

[0031] This device utilizes the waste collection component 7 in conjunction with the cutting mechanism 6. When aluminum cutting is required, the second electric push rod 662 is activated. The second electric push rod 662, with precise stroke control, pushes the bending arm 663 downward. The downward movement of the bending arm 663 causes the connected housing 664 to descend synchronously. As the housing 664 descends, the cutting blade disc 665, mounted at the bottom of the housing 664, gradually approaches the aluminum material. At this time, the fourth motor 666 is activated. The fourth motor 666, with its strong power output, drives the cutting blade... The cutting disc 665 rotates at high speed. After contacting the aluminum material, the high-speed rotating cutting disc 665 can stably and accurately cut the aluminum material. At the same time, the third motor 65 is started. When the third motor 65 is running, its output shaft drives the lead screw 63 to rotate. The rotation of the lead screw 63 drives the slider 64 to slide smoothly inside the top rail 62. The sliding of the slider 64 further drives the fixed plate 661 and the second electric push rod 662 mounted on the fixed plate 661 to move laterally. With the lateral movement of the second electric push rod 662... The cutting disc 665 also moves laterally, thus achieving linear cutting of the aluminum material through the lateral movement of the cutting disc 665. During the cutting process, the cutting debris generated is guided by the cutting groove 4 and falls smoothly into the collection frame 73 inside the side rail 71. When it is necessary to clean the debris in the collection frame 73, simply rotate the mounting screw 75 to move the mounting screw 75 upward and disengage it from the collection frame 73. At this time, the collection frame 73 and the sliding plates 72 on both sides can be easily pulled out, allowing the sliding plates 72 to be pulled out from the inside of the side rail 71, thereby achieving quick disassembly and installation of the collection frame 73. This design enables the device to not only have excellent automated cutting function and efficiently complete the cutting task of aluminum material, but also facilitate the collection and cleaning of debris generated during the cutting process, effectively improving the overall operating efficiency of the device and the cleanliness of the working environment. In addition, the waste collection component 7 and the automatically movable pre-pressing positioning mechanism 5 work together to realize a continuous automated cutting process, significantly improving the overall cutting convenience and cutting efficiency of the device.
