數(shù)控前送料剪板機(jī)工作原理（Working Principle of the CNC Front-feeding Plate Shearing Machine）：

板材輸送

• 上料：工人將待加工的金屬板材放置在剪板機(jī)的前送料裝置上，如送料平臺(tái)或送料輥道。也可通過自動(dòng)化上料設(shè)備，如機(jī)械手或吸盤裝置，將板材準(zhǔn)確地放置到送料位置。

• 送料控制：數(shù)控系統(tǒng)根據(jù)預(yù)先輸入的加工參數(shù)，如板材長度、剪切次數(shù)等，控制送料裝置的運(yùn)動(dòng)。送料裝置通常由伺服電機(jī)驅(qū)動(dòng)，通過滾珠絲杠或同步帶等傳動(dòng)機(jī)構(gòu)，帶動(dòng)板材向前移動(dòng)。伺服電機(jī)能夠精確控制送料的速度和位置，確保板材每次輸送的精度。

• 定位：當(dāng)板材輸送到指定位置時(shí)，送料裝置會(huì)停止運(yùn)動(dòng)，同時(shí)定位裝置會(huì)對板材進(jìn)行精確的定位，以保證剪切位置的準(zhǔn)確性。定位裝置可以是機(jī)械擋塊、光電傳感器或激光定位系統(tǒng)等。

剪切動(dòng)作

• 刀具驅(qū)動(dòng)：剪板機(jī)的剪切刀具由液壓系統(tǒng)或機(jī)械傳動(dòng)系統(tǒng)驅(qū)動(dòng)。在液壓驅(qū)動(dòng)的剪板機(jī)中，液壓泵將高壓油輸送到液壓缸，推動(dòng)刀具上下運(yùn)動(dòng)；在機(jī)械傳動(dòng)的剪板機(jī)中，電機(jī)通過皮帶、齒輪等傳動(dòng)機(jī)構(gòu)帶動(dòng)刀具運(yùn)動(dòng)。

• 剪切力計(jì)算：數(shù)控系統(tǒng)會(huì)根據(jù)板材的材質(zhì)、厚度和寬度等參數(shù)，計(jì)算出所需的剪切力，并控制液壓系統(tǒng)或機(jī)械傳動(dòng)系統(tǒng)提供相應(yīng)的動(dòng)力，確保刀具能夠順利地切斷板材。

• 刀具閉合：當(dāng)板材定位完成后，數(shù)控系統(tǒng)發(fā)出指令，驅(qū)動(dòng)刀具向下運(yùn)動(dòng)，與下刀片閉合，對板材進(jìn)行剪切。刀具的運(yùn)動(dòng)速度和行程也由數(shù)控系統(tǒng)精確控制，以保證剪切質(zhì)量。

數(shù)控系統(tǒng)控制

• 參數(shù)設(shè)置：操作人員通過數(shù)控系統(tǒng)的操作界面，輸入板材的尺寸、材質(zhì)、剪切長度、剪切次數(shù)等加工參數(shù)。數(shù)控系統(tǒng)會(huì)根據(jù)這些參數(shù)自動(dòng)生成加工方案，并控制送料裝置和剪切刀具的運(yùn)動(dòng)。

• 實(shí)時(shí)監(jiān)控：在加工過程中，數(shù)控系統(tǒng)會(huì)實(shí)時(shí)監(jiān)控送料裝置和剪切刀具的運(yùn)動(dòng)狀態(tài)，如位置、速度、壓力等。如果發(fā)現(xiàn)異常情況，如送料偏差、刀具磨損等，數(shù)控系統(tǒng)會(huì)及時(shí)發(fā)出警報(bào)，并自動(dòng)調(diào)整加工參數(shù)或停止加工，以保證加工質(zhì)量和設(shè)備安全。

• 數(shù)據(jù)存儲(chǔ)和調(diào)用：數(shù)控系統(tǒng)可以存儲(chǔ)多個(gè)加工方案，操作人員可以根據(jù)需要隨時(shí)調(diào)用這些方案，提高加工效率。同時(shí)，數(shù)控系統(tǒng)還可以記錄加工過程中的各種數(shù)據(jù)，如加工時(shí)間、剪切次數(shù)、板材消耗等，方便進(jìn)行生產(chǎn)管理和質(zhì)量追溯。

廢料處理

• 廢料分離：剪切完成后，板材被切斷成所需的長度，廢料會(huì)從剪板機(jī)的廢料出口排出。有些剪板機(jī)還配備了廢料分離裝置，能夠?qū)U料與成品板材自動(dòng)分離，提高生產(chǎn)效率。

• 廢料收集：排出的廢料會(huì)被收集到廢料箱或廢料輸送機(jī)上，以便進(jìn)行后續(xù)的處理，如回收利用或廢棄處理。

Plate Conveying

• Loading: Workers place the metal plates to be processed on the front-feeding device of the plate shearing machine, such as the feeding platform or the feeding roller table. Automated loading equipment, such as manipulators or suction cup devices, can also be used to accurately place the plates in the feeding position.

• Feeding Control: According to the pre-input processing parameters, such as the plate length and the number of shearing times, the CNC system controls the movement of the feeding device. The feeding device is usually driven by a servo motor, and the plate is driven to move forward through transmission mechanisms such as ball screws or synchronous belts. The servo motor can precisely control the feeding speed and position to ensure the accuracy of each plate feeding.

• Positioning: When the plate is conveyed to the specified position, the feeding device will stop moving. At the same time, the positioning device will accurately position the plate to ensure the accuracy of the shearing position. The positioning device can be a mechanical stop, a photoelectric sensor, or a laser positioning system, etc.

Shearing Action

• Tool Drive: The shearing tool of the plate shearing machine is driven by a hydraulic system or a mechanical transmission system. In a hydraulically driven plate shearing machine, the hydraulic pump delivers high-pressure oil to the hydraulic cylinder to push the tool to move up and down. In a mechanically driven plate shearing machine, the motor drives the tool to move through transmission mechanisms such as belts and gears.

• Shearing Force Calculation: The CNC system will calculate the required shearing force according to parameters such as the material, thickness, and width of the plate, and control the hydraulic system or the mechanical transmission system to provide the corresponding power to ensure that the tool can smoothly cut off the plate.

• Tool Closing: After the plate is positioned, the CNC system issues an instruction to drive the tool to move downward and close with the lower blade to shear the plate. The movement speed and stroke of the tool are also precisely controlled by the CNC system to ensure the shearing quality.

CNC System Control

• Parameter Setting: The operator inputs processing parameters such as the size, material, shearing length, and the number of shearing times of the plate through the operation interface of the CNC system. The CNC system will automatically generate a processing plan according to these parameters and control the movement of the feeding device and the shearing tool.

• Real-time Monitoring: During the processing, the CNC system will monitor the movement status of the feeding device and the shearing tool in real time, such as position, speed, and pressure. If an abnormal situation is detected, such as feeding deviation or tool wear, the CNC system will promptly issue an alarm and automatically adjust the processing parameters or stop the processing to ensure the processing quality and equipment safety.

• Data Storage and Retrieval: The CNC system can store multiple processing plans, and the operator can call these plans at any time as needed to improve processing efficiency. At the same time, the CNC system can also record various data during the processing, such as processing time, the number of shearing times, and plate consumption, which is convenient for production management and quality traceability.

Scrap Disposal

• Scrap Separation: After the shearing is completed, the plate is cut into the required length, and the scrap will be discharged from the scrap outlet of the plate shearing machine. Some plate shearing machines are also equipped with a scrap separation device, which can automatically separate the scrap from the finished plate to improve production efficiency.

• Scrap Collection: The discharged scrap will be collected in a scrap bin or a scrap conveyor for subsequent processing, such as recycling or disposal as waste.

板材上料

1. 放置板材：將待加工的板材放置在剪板機(jī)的前送料操作平臺(tái)上，注意板材的放置方向和位置要符合加工要求，并且要放置平穩(wěn)，避免板材在送料過程中發(fā)生晃動(dòng)或偏移。

2. 定位板材：通過數(shù)控系統(tǒng)控制前送料裝置，將板材準(zhǔn)確地定位到剪切位置。在定位過程中，可以使用測量工具對板材的位置進(jìn)行檢查和調(diào)整，確保板材的定位精度符合要求。

剪切加工

1. 啟動(dòng)剪切：確認(rèn)板材定位無誤后，按下啟動(dòng)按鈕，剪板機(jī)開始按照預(yù)設(shè)的程序和參數(shù)進(jìn)行剪切加工。在剪切過程中，要注意觀察設(shè)備的運(yùn)行狀態(tài)，如刀具的切削情況、板材的送料情況等，如有異常應(yīng)及時(shí)停機(jī)處理。

2. 監(jiān)控加工過程：操作人員應(yīng)時(shí)刻關(guān)注剪切過程，確保板材的剪切質(zhì)量。如果發(fā)現(xiàn)剪切尺寸不準(zhǔn)確、切口不平整等問題，應(yīng)及時(shí)調(diào)整相關(guān)參數(shù)或停止設(shè)備進(jìn)行檢查和維修。

3. 完成剪切：當(dāng)板材完成剪切后，剪板機(jī)自動(dòng)停止運(yùn)行。此時(shí)，操作人員可以將剪切好的板材取下，并進(jìn)行下一次的上料和剪切操作。

加工結(jié)束

1. 清理工作區(qū)域：加工結(jié)束后，關(guān)閉設(shè)備電源，清理工作區(qū)域，將剪下的廢料收集起來，保持工作環(huán)境的整潔。

2. 保養(yǎng)設(shè)備：對剪板機(jī)進(jìn)行日常保養(yǎng)，如清理刀具、潤滑各運(yùn)動(dòng)部件、清理機(jī)床導(dǎo)軌等，以延長設(shè)備的使用壽命和保證設(shè)備的性能。

3. 記錄數(shù)據(jù)：記錄本次加工的相關(guān)數(shù)據(jù)，如板材的材質(zhì)、規(guī)格、加工數(shù)量、加工時(shí)間等，以便于生產(chǎn)管理和質(zhì)量追溯。

1. Inspect the Equipment: Check the appearance of the equipment for any damage. Ensure that all components are in normal condition, the lubrication system is functioning properly, the levels of hydraulic oil and lubricating oil are within the normal range, the electrical system is operating normally, and all buttons and switches are sensitive.

2. Prepare Tools and Materials: Prepare the required plates, ensuring that the surface of the plates is flat, free of impurities, and their dimensions meet the processing requirements. At the same time, prepare corresponding measuring tools such as calipers and tape measures to measure and inspect the plates.

3. Install the Cutting Tools: Select appropriate cutting tools according to the processing requirements. When installing the tools, make sure they are firmly fixed and the clearance between the cutting edges is adjusted reasonably. Generally speaking, the clearance between the cutting edges should be adjusted according to the material and thickness of the plate. Plates with harder materials and greater thickness require a larger clearance between the cutting edges.

1. Power On: Turn on the power switch of the equipment and start the CNC system. Wait for the system to complete the self-check.

2. Parameter Setting: According to parameters such as the material, thickness, length, and width of the plate, set the corresponding shearing parameters in the CNC system, such as the shearing angle, the clearance of the blades, and the shearing stroke. Meanwhile, set the relevant parameters for front feeding, such as the feeding speed and the feeding length.

3. Program Compilation: If batch production or shearing of complex shapes is required, a shearing program can be compiled in the CNC system. The program can be edited according to actual needs, including the sequence and parameters of actions such as the positioning, feeding, and shearing of the plate.

1. Place the Plate: Place the plate to be processed on the front-feeding operation platform of the plate shearing machine. Pay attention that the placement direction and position of the plate should meet the processing requirements, and the plate should be placed steadily to avoid shaking or deviation during the feeding process.

2. Position the Plate: Control the front-feeding device through the CNC system to accurately position the plate at the shearing position. During the positioning process, measuring tools can be used to check and adjust the position of the plate to ensure that the positioning accuracy of the plate meets the requirements.

1. Start Shearing: After confirming that the plate is positioned correctly, press the start button, and the plate shearing machine will start the shearing process according to the preset program and parameters. During the shearing process, pay attention to observing the operation status of the equipment, such as the cutting condition of the tools and the feeding condition of the plate. If any abnormalities occur, stop the machine immediately for handling.

2. Monitor the Processing: The operator should always pay attention to the shearing process to ensure the shearing quality of the plate. If problems such as inaccurate shearing dimensions or uneven cutting edges are found, adjust the relevant parameters in a timely manner or stop the equipment for inspection and maintenance.

3. Complete Shearing: When the plate is sheared, the plate shearing machine will stop running automatically. At this time, the operator can remove the sheared plate and proceed with the next loading and shearing operation.

1. Clean the Working Area: After the processing is completed, turn off the power of the equipment, clean the working area, collect the cut waste materials, and keep the working environment clean.

2. Maintain the Equipment: Conduct daily maintenance on the plate shearing machine, such as cleaning the cutting tools, lubricating all moving parts, and cleaning the machine tool guide rails, to extend the service life of the equipment and ensure its performance.

3. Record Data: Record the relevant data of this processing, such as the material and specification of the plate, the processing quantity, and the processing time, to facilitate production management and quality traceability.
