Description

An intelligent sawing production line for sawing long and short aluminum bars Technical Field

[0001] The present invention mainly relates to the field of aluminum bar production and processing, and specifically to an intelligent sawing production line that is universal for sawing long and short aluminum bars. Background Art

[0002] The current aluminum bar production line has poor connections between various mechanisms, requiring manual intervention between each process, resulting in a low degree of automation. After sawing, manual framing and handling are still required, affecting overall production efficiency, resulting in high labor intensity, low safety, and excessively long production cycles. Furthermore, the current aluminum bar production model is single-minded, with one production line only producing aluminum bars within a certain sawing diameter range and unable to process different aluminum bars according to actual conditions. The details are as follows:

[0003] Currently, there are three types of aluminum bar sawing equipment in the aluminum processing industry: A. Manual sawing, which cuts 1-3 aluminum bars at a time and has low production capacity, high labor costs, and a low safety factor. B. Multi-bar automatic sawing lines for long and round bars, which cut 5-8 bars at a time, can achieve a certain degree of automation but have lower production capacity and are directly affected by the saw blade. For sawing bars with a wide diameter span, multiple sawing lines are required. C. Multi-bar band saws, which cut 5-15 bars at a time, are primarily used in sawing lines for aluminum flat ingots.

[0004] The above three saw types have certain limitations due to the characteristics of the machines themselves, and their scope of use and production capacity are affected by the equipment structure. Summary of the Invention

[0005] In order to solve the deficiencies of the prior art, the present invention provides a universal intelligent sawing production line for sawing long and short aluminum bars. It utilizes an intelligent production line to improve the efficiency of aluminum bar sawing by integrating and coordinating processes.

[0006] To achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions:

[0007] An intelligent sawing production line for sawing long and short aluminum bars, comprising a bar lifting and unloading mechanism for lifting aluminum bars from a smelting furnace; a bar storage and feeding mechanism for storing aluminum bars; a feeding trolley for pushing aluminum bars; and an aluminum bar conveying platform for conveying aluminum bars.

[0008] The aluminum bar conveying platform is provided with a first holding and pressing device, and a baffle mechanism is provided on one side of the first holding and pressing device. The baffle mechanism includes a serrated baffle. When the end of the aluminum bar contacts the serrated baffle, the first holding and pressing device presses the aluminum bar.

[0009] A gantry saw mechanism is provided between the first clamping and pressing device and the sawtooth baffle, and the saw head of the gantry saw mechanism can be adjusted up and down;

[0010] A second clamping and pressing device is provided on one side of the serrated baffle, and a digital sizing mechanism is provided on one side of the second clamping and pressing device. The digital sizing mechanism includes a sizing baffle, and the position of the sizing baffle is adjustable. When the end of the aluminum rod contacts the serrated baffle, the second clamping and pressing device presses the aluminum rod.

[0011] The end of the aluminum rod conveying platform is provided with a laser coding mechanism;

[0012] A discharge trolley and a discharge platform are provided on one side of the aluminum bar conveying platform, and the discharge trolley and the discharge trolley are used to discharge the aluminum bars after laser coding from the aluminum bar conveying platform;

[0013] One side of the feeding trolley is provided with a packing mechanism, a bundling mechanism and a weighing mechanism in sequence.

[0014] A control cabinet is provided on the gantry saw mechanism, and the hanging rod and reversing mechanism, feeding trolley, aluminum rod conveying platform, first clamping and pressing device, serrated baffle, gantry saw mechanism, second clamping and pressing device, digital sizing mechanism, laser coding mechanism, unloading trolley, packaging mechanism, bundling mechanism and weighing mechanism are all connected to the control cabinet.

[0015] A sawdust conveying and recycling mechanism is provided at the bottom of the gantry saw mechanism. The sawdust conveying and recycling mechanism includes a shell. An opening is provided at the top of the shell. When the saw head descends, the saw teeth of the saw head are located at the opening.

[0016] The aluminum rod conveying platform includes a conveying roller, a sprocket is provided at the end of the conveying pipe, a chain is provided on the sprocket, and the conveying roller conveys the aluminum rod through a chain and sprocket mechanism.

[0017] The packaging mechanism adopts a V-shaped frame structure.

[0018] The first holding and pressing device and the second holding and pressing device are both driven by hydraulic cylinders.

[0019] The production line also includes a base plate.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] This automated aluminum bar sawing production line utilizes a gantry saw as its main structure, capable of sawing aluminum bars ranging from φ80 to φ600. This eliminates the need for multiple units and utilizes a more sophisticated control scheme, replacing the original hydraulic control system with a servo motor and ball screw combination, further enhancing control accuracy.

[0022] The rod conveying and storage platform has been increased from 600-900mm to 3000-4000mm, significantly increasing the number of aluminum rods that can be sawn in a single pass and reducing the time spent on conveying rods from 5-7 times to just one. This significantly improves equipment utilization and increases production capacity. The corresponding equipment mechanisms have been industrialized and upgraded, achieving a heavy-duty industrial production line upgrade and improving production efficiency.

[0036] The present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the contents of the present invention, those skilled in the art may make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present application.

[0037] The standard parts used in this application can all be purchased from the market, and special-shaped parts can be customized according to the instructions and drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, and bonding in the existing technology, and the components used for circuit connection are all conventional models in the existing technology.

[0038] At the same time, in order to clearly express the connection relationship and working principle between the various components and highlight the key points, the drawings in the specification are organized and drawn in the form of simple diagrams. One simple diagram can correspond to a variety of materials and actual external structural shapes.

[0039] An intelligent sawing production line for sawing both long and short aluminum bars. Its main structure includes a bar hoisting and unloading mechanism 1 for hoisting aluminum bars 19 from a smelting furnace; a bar storage and feeding mechanism 2 for storing aluminum bars 19; a feeding trolley 3 for pushing aluminum bars 19; and an aluminum bar 19 conveying platform 4 for conveying aluminum bars 19. As shown in the accompanying drawings, the cycle time for casting aluminum bars 19 is 1 to 1.5 hours per casting. The cycle time of the smelting furnace, that is, for casting aluminum molten aluminum bars, is 3 to 4 hours per furnace. In other words, the time required to lift semi-finished aluminum bars 19 from the casting pit cannot exceed 1 hour to ensure continuous use of the subsequent casting pit. Therefore, the aluminum bars 19 must be quickly lifted to the storage rack for easy sawing.

[0040] Due to the limited sawing efficiency, the lack of fast sawing capability will lead to congestion in the casting pit. Secondary transfer and intermediate storage are required, and the newly developed gantry sawing line can quickly saw and meet the requirements. The attached figure uses multiple storage rod racks, multiple horizontal feed trolleys 3, and a sawing conveyor platform with a span of 3-4 meters, which can solve the problem of traditional one-time sawing machines blocking the previous process.

[0041] The aluminum rod 19 conveying platform 4 is provided with a first holding and pressing device 5, and a baffle mechanism 6 is provided on one side of the first holding and pressing device. The baffle mechanism includes a serrated baffle that can move up and down. When the end of the aluminum rod 19 contacts the serrated baffle, the first holding and pressing device 5 presses the aluminum rod 19;

[0042] A gantry saw mechanism 7 is located between the first clamping and pressing device 5 and the sawtooth baffle. The saw head of the gantry saw mechanism 7 can be adjusted vertically and laterally. As shown in the accompanying drawings, the gantry saw mechanism 7 can adjust the position of the saw teeth horizontally and vertically, resulting in high sawing efficiency and rapid production. The sawing cycle for 40 aluminum bars 19 is just 4 minutes.

[0043] A second clamping and pressing device 8 is provided on one side of the serrated baffle, and a digital sizing mechanism 9 is provided on one side of the second clamping and pressing device 8. The digital sizing mechanism 9 includes a sizing baffle, and the position of the sizing baffle is adjustable; when the end of the aluminum rod 19 contacts the serrated baffle, the second clamping and pressing device 8 presses the aluminum rod 19; the position of the digital sizing is set according to production needs, and the sizing device adopts servo precision control, which can meet the requirements of sawing lengths of various aluminum rods 19.

[0044] Furthermore, a laser coding mechanism 10 is provided at the end of the aluminum rod 19 conveying platform 4, which is used for laser coding the aluminum rod 19 after cutting.

[0045] A discharge trolley 11 and a discharge platform 12 are provided on one side of the aluminum rod 19 conveying platform 4. The structures of the discharge trolley 11 and the discharge platform 12 are the same as those of the rod storage and feeding mechanism 2 and the feeding trolley 3, and are used to unload the aluminum rods 19 after laser coding from the aluminum rod 19 conveying platform 4;

[0046] Furthermore, one side of the feeding trolley 3 is provided with a packing mechanism 13, a bundling mechanism 14 and a weighing mechanism 15. As shown in the accompanying drawings, the packing mechanism 13, the bundling mechanism 14 and the weighing mechanism 15 are used to pack, bundle and weigh the aluminum bars 19, further enhancing the processing efficiency of the aluminum bars 19.

[0047] The gantry saw mechanism 7 is provided with a control cabinet 16. The rod lifting and reversing mechanism 1, the feeding trolley 3, the aluminum rod 19 conveying platform 4, the first clamping and pressing device 5, the sawtooth baffle, the gantry saw mechanism 7, the second clamping and pressing device 8, the digital sizing mechanism 9, the laser coding mechanism 10, the unloading trolley 11, the packaging mechanism 13, the bundling mechanism 14 and the weighing mechanism 15 are all connected to the control cabinet 16, thereby improving the automation level of the production line and improving production efficiency. In one embodiment of the present invention, the control cabinet 16 adopts a PLC control system. The PLC has high reliability and strong anti-interference ability. It is equivalent to the control circuit of the relay contactor control system, is simple to use, and is easy to debug and maintain. The control of the PLC signal can adopt a push button switch or a touch screen called Siemens. In actual use, it is specially set in an electrical cabinet and connected to the actuator to be controlled through a wire. The operation is simple and convenient.

[0048] A sawdust conveying and recovery mechanism 17 is provided at the bottom of the gantry saw mechanism 7. The sawdust conveying and recovery mechanism 17 includes a housing with an opening at the top. When the saw head is lowered, the saw teeth of the saw head are positioned within the opening. As shown in FIG12 , the sawdust conveying and recovery mechanism 17 is separated from the gantry saw mechanism 7. When the saw head is lowered, the saw teeth can enter the opening. An internal fan is provided to absorb debris generated during the sawing process. Since both the debris and the aluminum rod 19 generate heat during the sawing process, timely absorption and removal of the sawdust effectively protects the aluminum rod 19 and the saw teeth after sawing.

[0049] The aluminum bar 19 conveying platform 4 includes a conveying roller, a sprocket is provided at the end of the conveying tube, and a chain is provided on the sprocket. The conveying roller conveys the aluminum bar 19 through a chain-sprocket mechanism. As shown in Figure 5, a sprocket is provided at the end of the conveying roller, and a chain is provided on the sprocket. A single conveying roller is rotated by a motor, thereby driving the entire conveying roller to rotate, further improving conveying efficiency.

[0050] The packaging mechanism 13 adopts a V-shaped frame structure. As shown in Figures 9 and 10, the V-shaped frame structure can automatically stack the cut aluminum bars 19, making it easier for the subsequent bundling mechanism 14 to perform bundling.

[0051] The first clamping device 5 and the second clamping device 8 are both driven by hydraulic cylinders. As shown in Figure 6, the first clamping device 5 and the second clamping device 8 are driven by hydraulic cylinders, so that the clamping plates on both sides can smoothly release and clamp the aluminum rod 19, maintaining stability in the clamped state to ensure smooth cutting.

[0052] The production line further comprises a bottom plate 18. As shown in Figures 1 to 3, the bottom plate 18 closely links together the various process devices for cutting the aluminum rod 19 to form a whole, further enhancing the relevance between the production lines. Example

[0053] When sawing aluminum bars 19, the semi-finished aluminum bars 19 are first quickly lifted from the casting pit by the bar lifting and unloading mechanism 1 to the bar storage and feeding mechanism 2, and then transported by the feeding trolley 3 to the aluminum bar 19 conveying platform 4: When the aluminum bar 19 blank is 6500mm, the aluminum bar 19 is transferred to the baffle mechanism 6 to work at 150mm. The baffle mechanism 6 operates, and the fixed-length baffle rises to block the aluminum bar 19. At this time, the first clamping and pressing device 5 starts working, tightening the aluminum bar 19 to the rated pressure, pressing the aluminum bar 19, and the sawing machine starts working. After descending to the rated height, it moves horizontally to cut off the front end of the aluminum bar 19;

[0054] Then, the first clamping and pressing device 5 is released, the sawtooth baffle descends, and the aluminum bar 19 is transported forward to the position of the fixed-length baffle. The fixed-length position is set according to production needs. The fixed-length device implements servo precision control. After contacting the fixed length, the second clamping and pressing device 8 starts working. After reaching the rated pressure, the aluminum bar 19 is pressed, and the sawing machine starts working and sawing normally. The finished product is completed after two sawings.

[0055] After sawing is completed, the finished aluminum bars 19 continue to be transported and the subsequent coding, unloading, packaging, bundling and weighing are completed. Example

[0056] When sawing aluminum bars 19, the semi-finished aluminum bars 19 are first quickly lifted from the casting pit by the bar lifting and unloading mechanism 1 to the bar storage and feeding mechanism 2, and then transported by the feeding trolley 3 to the aluminum bar 19 conveying platform 4: When the aluminum bar 19 blank is 12.5m long and the aluminum bar 19 is conveyed to the baffle mechanism 6 at a distance of 150mm, the baffle mechanism 6 operates, and the fixed-length baffle rises to block the aluminum bar 19. At this time, the first clamping and pressing device 5 starts working, tightening the aluminum bar 19 to the rated pressure, pressing the aluminum bar 19, and the sawing machine starts working. After descending to the rated height, the saw moves horizontally to cut off the front end of the aluminum bar 19;

[0057] Then release the first clamping and pressing device 5, the fixed-length baffle drops, and the aluminum bar 19 is transported forward to the position of the fixed-length baffle. The fixed-length position is set according to production needs. The fixed-length device realizes servo precision control. After contacting the fixed length, the first clamping device and the second clamping and pressing device 8 start working at the same time. After reaching the rated pressure, the aluminum bar 19 is pressed, and the sawing machine starts working for the second sawing;

[0058] After the second sawing is completed, the first clamping and pressing device 5 and the second clamping and pressing device 8 are released, and the aluminum rod 19 continues to be transported forward to the position of the fixed-length baffle. The fixed-length device realizes servo precision control and repeats the previous action of clamping, pressing the rod, sawing, and releasing the clamp to complete this cycle of sawing.

[0059] After sawing is completed, the finished aluminum bars 19 continue to be transported and the subsequent coding, unloading, packaging, bundling and weighing work are completed.
