Detailed Implementation

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] like Figures 1-6 As shown, an automated high-speed cutting system for aluminum forging raw materials includes a control system and, controlled by the control system, a raw material feeding unit (not shown), a clamping and cutting unit 1, a waste cleaning unit 2, a lifting and measuring unit 3, and a finished product unloading and sorting unit 4. The raw material feeding unit is equipped with a first length detection mechanism for detecting the length of the raw material. The first length detection mechanism feeds back the detected length to the control system. The control system analyzes and calculates the cutting data to generate a cutting command and sends it to the clamping and cutting unit 1. The clamping and cutting unit 1 performs clamping and cutting operations on the raw material according to the cutting command.

[0032] After cutting, the workpiece is conveyed to the waste cleaning unit 2 via the roller conveyor mechanism 5 for waste cleaning. A side pushing mechanism 6 is provided on one side of the end of the roller conveyor mechanism 5. The side pushing mechanism 6 pushes the cleaned workpiece to the temporary storage area 7. The lifting and measuring unit 3 is set between the temporary storage area 7 and the finished product unloading and sorting unit 4. The lifting and measuring unit 3 measures the length and weighs each workpiece in sequence, lifts it, and sends it to the finished product unloading and sorting unit 4.

[0033] The finished product unloading and sorting unit 4 includes a U-shaped conveyor 41, a second length detection mechanism 42, an industrial robot 43, a storage area 44, and a scrap area. The U-shaped conveyor 41 transports the workpiece along a U-shape, and its outlet end is equipped with a fixed baffle 45. The second length detection mechanism 42 is located on one side of the fixed baffle 45. The second length detection mechanism 42 detects the workpiece and feeds back the detected length to the control system. The control system compares and analyzes the detected length with the set length and generates an unloading command for the industrial robot 43. The industrial robot 43 sends qualified workpieces to the storage area 44 and unqualified workpieces to the scrap area.

[0034] The high-speed automated cutting system for aluminum forging raw materials of this invention is fully automated, enabling automatic sorting and collection of qualified and defective products. It replaces heavy manual operations, reduces reliance on workers and labor costs, and achieves "unmanned" operation, significantly improving production efficiency. It can operate continuously for 24 hours a day, and the entire process is digitally controlled by the control system. Process parameters are adjustable and storable, and production data is monitored and recorded in real time, facilitating quality traceability and lean production management. It can also ensure the consistency of workpiece cutting length and weight, greatly improving the quality of subsequent forging and material utilization. Furthermore, the high-speed automated cutting system for aluminum forging raw materials of this invention has safety protection effects, eliminating personal injury accidents and improving safety during operation.

[0035] like Figure 2 As shown, the lifting and measuring unit 3 includes a weighing lifting mechanism 31 and a third length detection mechanism 32. The weighing lifting mechanism 31 includes a feeding ramp 311, a weighing frame 312, and a driving mechanism 313. The feeding ramp 311 is located at the conveying inlet of the U-shaped conveyor 41. The height of the inlet end of the feeding ramp 311 is higher than the height of the outlet end of the temporary storage area 7. The weighing frame 312 is located between the feeding ramp 311 and the temporary storage area 7. The third length detection mechanism 32 is located on one side of the weighing frame 312. The weighing frame 312 is used to weigh a single workpiece and is driven up and down by the driving mechanism 313 to lift the single workpiece down along the feeding ramp 311 to the U-shaped conveyor 7 for transmission.

[0036] Here, the inclined plane of the temporary storage area can slide down, allowing a single workpiece to fall onto the weighing frame for weighing. The length of the workpiece is then detected by the third length detection mechanism 32. After detection, the drive mechanism 313 is activated to move the weighing frame 312 up to a certain height, so that the workpiece can slide into the U-shaped conveyor 41 along the unloading ramp of the unloading ramp frame 311.

[0037] The design of this weighing and lifting mechanism can avoid the problem of uneven material distribution in raw materials and improve the pass rate in the subsequent forging process. By sending the weighing data of a single workpiece to the control system, the control system analyzes and compares the data. When the weighing weight is significantly lower than the theoretical weight, the control system sends a feeding instruction to the industrial robot to send the workpiece to the scrap area.

[0038] like Figure 2 As shown, baffles 8 are provided on both sides of the temporary storage area 7, and a protective plate 9 is connected to the front end of the baffles 8. The protective plate 9 is located on the outside of the weighing frame 312. A support plate 314 is installed at the bottom of the weighing frame 312. A weighing sensor is installed on the support plate 314. The driving mechanism is a driving cylinder. The output end of the driving cylinder passes through the support plate 314 and is fixed to the weighing frame 312. Here, the design of the baffles 8 prevents the workpiece from rolling out when it slides down the slope of the temporary storage area 7. The design of the protective plate 9 prevents the workpiece from falling out during the lifting process, ensuring safety during the transfer process.

[0039] like Figure 2 As shown, a guide plate for limiting the transmission of a single workpiece is provided on the outer side of the first corner of the U-shaped conveyor 41, and a side-pushing mechanism 6 is provided at the second corner of the U-shaped conveyor 41. Specifically, in this embodiment, the side-pushing mechanism 6 includes a pushing cylinder and a pushing plate, and the output end of the pushing cylinder is fixed to the pushing plate. The design of the side-pushing mechanism on one side of the roller conveying mechanism facilitates the removal of workpieces from the roller conveying mechanism 5 to the temporary storage area. The design of the side-pushing mechanism at the corner of the U-shaped conveyor 41 facilitates the reversal during the conveying process.

[0040] like Figure 3 As shown, the waste cleaning unit 2 includes a brush cleaning mechanism 21 and a waste collection box 22. The brush cleaning mechanism 21 is located above the roller conveying mechanism 5 on one side, and the waste collection box 22 is located below the roller conveying mechanism 5, with a waste discharge area 221 on one side. Here, the brush cleaning mechanism 21 is designed to clean the waste from the cut workpiece. Of course, an air blowing cleaning mechanism can also be designed here to improve the cleaning effect. The cleaned waste falls into the waste collection box 22 and can also be discharged from the waste discharge area 221 on one side.

[0041] Specifically, in this embodiment, the first length measuring mechanism (not shown in the figure) is a laser sensor; here, the length of the raw material is detected by the first length measuring mechanism, and the detected length is fed back to the control system. The control system generates a cutting command by analyzing and calculating the cutting data and sends it to the clamping and cutting unit 1, such as the target cutting length L, the number of cuts N, etc., and cooperates with the clamping and cutting unit 1 to realize the cutting of the raw material.

[0042] In this embodiment, both the second length detection mechanism 42 and the third length detection mechanism 32 are pneumatic ejection detection mechanisms, such asFigure 5 As shown, the pneumatic ejection detection mechanism includes an ejection cylinder 421, an ejector pin 422, and a displacement sensor. The ejection cylinder 421 is mounted on one side of the fixed baffle 45 / weighing frame 312 via a cylinder mounting base 423, and its output end is connected to the ejector pin 422. The displacement sensor is mounted on the ejection cylinder 421. The ejection cylinder 421 pushes the ejector pin 422 to push the workpiece to the fixed baffle 45 to detect the length of the workpiece. Specifically, the second length detection mechanism 42 is a pneumatic ejection detection mechanism. The ejection cylinder 421 pushes the ejector pin 422 to push the workpiece to the fixed baffle 45 to detect the length of the workpiece.

[0043] The displacement sensor directly monitors the extension length of the piston rod, i.e., the movement distance L of the ejector pin. 顶出 Actual length L of the workpiece 工件 =L 挡板 -L 顶出 ,

[0044] L 挡板 : Fixed distance from the fixed baffle to the initial position of the cylinder (known value);

[0045] L 顶出 Real-time reading of the sensor when the ejector pin contacts the fixed baffle.

[0046] Specifically, the storage area 44 includes at least one set of slide rails 441 and a storage rack 442. The set of slide rails 441 includes a high slide rail 4411 and a low slide rail 4412 arranged opposite to each other. The bottom of the storage rack 442 is slidably mounted on the high slide rail 4411 and the low slide rail 4412, respectively. Figure 6 As shown, the storage rack 442 in this invention is oriented with the left side higher than the right side and is set obliquely on the slide rail. It needs to be placed on the rail by a forklift first, and then its position is fixed by limiting components. Here, the storage rack design with a certain oblique angle utilizes the principle of inertia to prevent the workpieces from rolling left and right after being placed from low to high, thus reducing the probability of scratches on the products.

[0047] Specifically, in this embodiment, the high-speed cutting automation system for aluminum forging raw materials also includes a safety protection unit, which includes a safety protection net 10. The safety protection net 10 is set outside the waste cleaning unit 2, the lifting and measuring unit 3, and the finished product unloading and sorting unit 4. The control system of this invention integrates a safety protection system: through a fully enclosed or semi-enclosed safety protection net 10, personnel are prevented from contacting dangerous areas. A safety light curtain or laser scanner can be set in the sawing area to immediately stop the sawing action when personnel intrusion is detected. Emergency stop buttons are set in key parts of the equipment.

[0048] The control system in this invention coordinates and controls the action sequence and rhythm of all mechanisms, including the raw material feeding unit, clamping and cutting unit 1, waste cleaning unit 2, lifting and measuring unit 3, and finished product unloading and sorting unit 4. It receives and processes real-time signals from length measuring sensors (laser sensors, position sensors) from the first length detection mechanism, the second length detection mechanism 42, and the third length detection mechanism 32, and realizes high-precision closed-loop positioning control based on the target length.

[0049] It can store and recall optimized cutting process parameters (saw blade speed, feed rate, clamping force, etc.) for aluminum bars of different specifications (diameter, length).

[0050] Provides a human-machine interface (HMI): for setting cutting parameters (length, quantity), selecting recipes, starting and stopping equipment, monitoring equipment status (running, alarms, maintenance prompts), and viewing production reports (quantity, length, efficiency, fault records);

[0051] Safety interlock control: By integrating safety light curtains, emergency stop buttons, door lock switches, etc., the equipment is ensured to operate in a safe state;

[0052] Data communication interface: Supports connection with factory MES / ERP systems to upload production data.

[0053] Cycle and Counting: The main conveyor line sends the remaining aluminum rod (or the next section to be cut) back to the initial positioning position; the steps are repeated for the next cut; the system automatically counts, and stops the cycle when the set quantity N is reached or the raw material is used up; the cut workpiece is conveyed by the roller conveyor mechanism.

[0054] Monitoring and Management: The system displays the current cutting length, quantity cut, equipment status (running, alarm), and status of each unit in real time via HMI; the system records production data (time, length, quantity, alarm information) and can export reports; when an anomaly occurs (such as positioning error, sawing overload, safety trigger), the system immediately stops and issues an alarm.

[0055] The working principle of the high-speed cutting automation system for aluminum forging raw materials of the present invention is as follows:

[0056] 1. Initialization:

[0057] The operator sets the parameters for this production task (aluminum rod specifications, target cutting length L, cutting quantity N) through the HMI, selects the corresponding process formula, and waits for the system to pass the self-check.

[0058] 2. Automatic feeding:

[0059] The raw material feeding unit is equipped with material level detection and material shortage alarm; the feeding mechanism of the raw material feeding unit is equipped with aluminum rod diameter / position recognition function (such as photoelectric sensor, automatic length measurement) to adapt to raw materials of different specifications;

[0060] Specifically, the raw material feeding unit of this invention can be fed by a robot. The aluminum rod is placed stably at the starting position of the main conveyor line of the raw material feeding unit, and then the main conveyor line is started. The aluminum rod is conveyed forward. When the aluminum rod approaches the positioning point, the conveyor line decelerates.

[0061] Here, a servo drive system for a wave-shaped anti-slip belt conveyor can be used, driven by a motor (servo / frequency converter) to achieve stability during the movement of aluminum bars; the conveying is mainly an automated conveying device that precisely controls the movement of the conveyor belt / roller through a servo motor. The core principle is: the servo driver receives control commands from the control system → adjusts the motor speed and position in real time → drives the conveying mechanism to start / stop / change speed with millimeter-level precision, thereby achieving point-to-point conveying of raw materials;

[0062] 3. Precision length measurement and clamping cutting:

[0063] The first length detection mechanism feeds back the detected length to the control system. The control system generates a cutting command by analyzing and calculating the cutting data based on the set target cutting length and sends it to the clamping and cutting unit. This invention avoids the possibility of excessively long or ineffective cutting due to human error and lack of optimized material arrangement algorithm, which would increase material loss. This invention can improve the utilization rate of materials.

[0064] Here, combined with a non-contact length measuring unit, a high-precision laser rangefinder or machine vision system is used to accurately measure the distance from the front end of the aluminum rod to the sawing position (or fixed reference point). Based on the target cutting length and the real-time feedback from the non-contact length measuring unit, the control system accurately calculates the distance that needs to be compensated, drives the conveyor line to move the aluminum rod forward slightly, so that its front end accurately reaches the theoretical sawing position, ensuring that the cutting length is highly consistent (accuracy can reach ±0.1mm), which greatly improves the subsequent forging quality and material utilization rate (reducing scrap and material loss).

[0065] Specifically, by activating a high-precision laser rangefinder, the actual distance `D_actual` from the front end of the aluminum rod to the theoretical cutting surface (or a fixed reference point) is measured.

[0066] The target position offset `ΔL = L_target - D_actual` (or equivalent calculation) is calculated through the control system.

[0067] By controlling the servo drive system, the conveyor line is precisely driven to move the aluminum bar forward by a distance `ΔL`, ensuring that the front end of the aluminum bar accurately reaches the set sawing position. This process is a closed-loop control, ensuring positioning accuracy (±0.1mm or higher).

[0068] Specifically, the clamping and cutting unit in this embodiment employs a clamping mechanism and a cutting mechanism. For example, a hydraulic or pneumatic clamping mechanism (such as a V-jaw) is provided at the sawing position to firmly clamp the aluminum rod instantly before cutting, preventing vibration and displacement, and ensuring cutting accuracy and safety. Then, the cutting mechanism is started, and the spindle motor drives the saw blade to rotate at high speed to the set speed. At the same time, the servo feed system drives the saw head to feed smoothly at the set speed, and high-speed rotation cutting begins. After the saw blade completely cuts through the aluminum rod, the feed system returns to its original position according to the set trajectory, and the spindle stops rotating. Of course, a high-efficiency coolant spray system can also be equipped here, using micro-lubrication MQL or wet cooling, which is precisely sprayed onto the sawing point to reduce the saw blade temperature, reduce aluminum chips sticking to the blade, extend the saw blade life, and improve the quality of the cut surface.

[0069] 4. Waste removal:

[0070] The cut aluminum rods are conveyed by the roller conveyor mechanism 5 and cleaned by the brush cleaning mechanism 21. The cleaned waste falls from the gap between the rollers of the roller conveyor mechanism 5 into the waste collection box 22. Then, the aluminum rods are pushed away from the roller conveyor mechanism 5 by the side push mechanism at the end and enter the temporary storage area 7. Of course, an air nozzle blowing mechanism can also be used here to improve the waste cleaning efficiency.

[0071] 5. Lifting Measurement:

[0072] The aluminum rods that enter the temporary storage area 7 roll down the temporary storage area 7 and fall onto the weighing frame 312. They are weighed by the weighing sensor and the length of the cut workpiece is measured by the third length detection mechanism 32 (high-precision laser rangefinder). After the measurement is completed, the weighing frame 312 is driven to move upward by the drive mechanism 313 until a single workpiece can fall down the unloading ramp 311 onto the U-shaped conveyor 41.

[0073] One or more brush cleaning mechanisms 21 can be added to the U-shaped conveyor 41 to perform further cleaning of waste chips and improve the surface cleanliness of the workpiece.

[0074] 6. Material feeding and sorting

[0075] The workpiece is conveyed along the U-shaped conveyor 41 until it enters the inner side of the fixed baffle 45. The inner side of the fixed baffle 45 can only accommodate a single workpiece. The length of the workpiece is detected by the second length detection mechanism 42, and the detected length is fed back to the control system. The control system compares and analyzes the detected length with the set length and generates a feeding instruction to the industrial robot 43. The industrial robot 43 sends qualified workpieces to the storage area 44 and unqualified workpieces to the scrap area. In this embodiment, the end of the industrial robot 43 uses an elliptical vacuum suction cup to pick up the workpiece and remove it from the fixed baffle 45. According to the detected length, the workpiece is placed in the storage area and the scrap area respectively.

[0076] The above description is merely a preferred embodiment of the present invention and should not be construed as limiting the scope of the invention. Therefore, any equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.
