数控前送料剪板机工作原理（Working Principle of the CNC Front-feeding Plate Shearing Machine）：
数控前送料剪板机是一种自动化程度较高的金属板材加工设备，它结合了数控技术和前送料系统，能够精确地对板材进行剪切操作。以下是其工作原理的详细介绍：
上料：工人将待加工的金属板材放置在剪板机的前送料装置上，如送料平台或送料辊道。也可通过自动化上料设备，如机械手或吸盘装置，将板材准确地放置到送料位置。
送料控制：数控系统根据预先输入的加工参数，如板材长度、剪切次数等，控制送料装置的运动。送料装置通常由伺服电机驱动，通过滚珠丝杠或同步带等传动机构，带动板材向前移动。伺服电机能够精确控制送料的速度和位置，确保板材每次输送的精度。
定位：当板材输送到指定位置时，送料装置会停止运动，同时定位装置会对板材进行精确的定位，以保证剪切位置的准确性。定位装置可以是机械挡块、光电传感器或激光定位系统等。
刀具驱动：剪板机的剪切刀具由液压系统或机械传动系统驱动。在液压驱动的剪板机中，液压泵将高压油输送到液压缸，推动刀具上下运动；在机械传动的剪板机中，电机通过皮带、齿轮等传动机构带动刀具运动。
剪切力计算：数控系统会根据板材的材质、厚度和宽度等参数，计算出所需的剪切力，并控制液压系统或机械传动系统提供相应的动力，确保刀具能够顺利地切断板材。
刀具闭合：当板材定位完成后，数控系统发出指令，驱动刀具向下运动，与下刀片闭合，对板材进行剪切。刀具的运动速度和行程也由数控系统精确控制，以保证剪切质量。
参数设置：操作人员通过数控系统的操作界面，输入板材的尺寸、材质、剪切长度、剪切次数等加工参数。数控系统会根据这些参数自动生成加工方案，并控制送料装置和剪切刀具的运动。
实时监控：在加工过程中，数控系统会实时监控送料装置和剪切刀具的运动状态，如位置、速度、压力等。如果发现异常情况，如送料偏差、刀具磨损等，数控系统会及时发出警报，并自动调整加工参数或停止加工，以保证加工质量和设备安全。
数据存储和调用：数控系统可以存储多个加工方案，操作人员可以根据需要随时调用这些方案，提高加工效率。同时，数控系统还可以记录加工过程中的各种数据，如加工时间、剪切次数、板材消耗等，方便进行生产管理和质量追溯。
The CNC front-feeding plate shearing machine is a metal plate processing equipment with a high degree of automation. It combines CNC technology with a front-feeding system and can accurately perform shearing operations on metal plates. The following is a detailed introduction to its working principle:
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.
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.
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 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.

What is the operating procedure of the CNC front-feeding plate shearing machine?
Preparatory Work
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.
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.
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.
Program Setting
Power On: Turn on the power switch of the equipment and start the CNC system. Wait for the system to complete the self-check.
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.
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.
Plate Loading
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.
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.
Shearing Process
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.
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.
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.
After Processing
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.
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.
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.

A large-scale floor-type boring and milling machine is used, and the precision machining is carried out by the one-time machining method to ensure the machining accuracy.
The hydraulic guillotine structure with three-point supported rolling bearings eliminates the support clearance and improves the shearing accuracy.
The hydraulic system adopts an integral logic circuit, with stable operation, low noise, and simple maintenance.
Japanese NOK seals are used; specially made oil cylinders control the operation of the knife plate.
The material pressing device adopts an integral circuit and independent parallel clamping cylinders. When the plate is uneven, it can freely stretch and press against the plate.
It is controlled by electricity, and fixed-stroke shearing can be realized, and the shearing stroke is adjustable.
The electrical control is centralized and reliable, as follows:
The power facilities are all installed inside the machine body, and the operation, control, and realization are carried out through the buttons on the control panel. A foot switch is provided, and the shearing action can be directly operated through it, which is convenient and fast. The overload and short circuit of the motor are protected by an air switch.
The hydraulic system is safe and reliable.
The upper and lower knives are made of high-quality HK13/6Crw2si or imported DA53 materials, and all are heat-treated to ensure that they have sufficient hardness and a long service life.
The ball-type worktable and the front material supporting device make the feeding convenient and ensure that the workpiece is not scratched during operation. The CNC rear stop gauge device adopts high-performance servo motors and drivers, and the precision ball screw drive positioning accuracy is ≤±0.15mm.
