HTB(G)-DA69W系列電液伺服數(shù)控折彎機(jī)( Series Electro-hydraulic Servo CNC Press Brake)工作原理Working Principle

      HTB(G)-DA69W系列8 + 1軸加機(jī)械工作臺補(bǔ)償電液伺服數(shù)控折彎機(jī)的工作原理融合了多軸聯(lián)動控制、電液伺服驅(qū)動以及獨(dú)特的機(jī)械工作臺補(bǔ)償機(jī)制，具體如下：

1. 電液伺服驅(qū)動原理：該折彎機(jī)采用先進(jìn)的電液伺服系統(tǒng)。數(shù)控系統(tǒng)會根據(jù)操作人員預(yù)先輸入的加工參數(shù)（如板材材質(zhì)、厚度、折彎角度、折彎長度等），經(jīng)過精確的計(jì)算和分析后，向電液伺服閥發(fā)出對應(yīng)的電信號。電液伺服閥依據(jù)這些電信號來精確控制液壓油的流量和流向，進(jìn)而驅(qū)動液壓缸，實(shí)現(xiàn)對滑塊運(yùn)動的精準(zhǔn)控制，包括滑塊的下降速度、停止位置以及施加的壓力等，以確保折彎操作的準(zhǔn)確性和穩(wěn)定性。

2. 8 + 1軸聯(lián)動控制：“8 + 1軸” 意味著該折彎機(jī)具備多個可獨(dú)立運(yùn)動且又能協(xié)同工作的軸。其中8軸通常涵蓋了滑塊的垂直運(yùn)動軸（控制上下行程以實(shí)現(xiàn)折彎動作）、后擋料的多個定位軸（用于精確確定板材的位置，保證每次折彎的尺寸精度）等。另外1軸可能是指特定的輔助軸或具有特殊功能的軸。這些軸在數(shù)控系統(tǒng)的協(xié)調(diào)和控制下，能夠按照預(yù)設(shè)的程序和軌跡進(jìn)行聯(lián)動運(yùn)動，使得折彎機(jī)可以處理各種復(fù)雜的折彎任務(wù)，滿足不同形狀和尺寸的板材加工需求。

3. 機(jī)械工作臺補(bǔ)償原理：在折彎過程中，由于工作臺在承受較大壓力時會產(chǎn)生一定的變形，這種變形會影響到折彎的精度。為了克服這一問題，該折彎機(jī)配備了機(jī)械工作臺補(bǔ)償裝置。當(dāng)滑塊向下運(yùn)動對板材施加壓力進(jìn)行折彎時，工作臺的變形情況會被檢測裝置實(shí)時監(jiān)測（可能通過傳感器等設(shè)備）。數(shù)控系統(tǒng)根據(jù)檢測到的變形數(shù)據(jù)，計(jì)算出需要補(bǔ)償?shù)牧?，并控制機(jī)械補(bǔ)償裝置（如通過絲桿、螺母機(jī)構(gòu)等）對工作臺的相應(yīng)部位進(jìn)行微調(diào)，增加或減少工作臺的局部高度，從而補(bǔ)償因工作臺變形而導(dǎo)致的折彎誤差，確保折彎角度和尺寸的高精度，提高加工質(zhì)量。

4. 模具配合與折彎過程：折彎機(jī)上安裝有特定形狀和尺寸的上、下模具。上模具固定在滑塊上，下模具安裝在工作臺上。當(dāng)滑塊在電液伺服系統(tǒng)的驅(qū)動下向下運(yùn)動時，板材被放置在上、下模具之間，隨著滑塊的繼續(xù)下壓，板材在模具的作用下發(fā)生塑性變形，逐漸達(dá)到所需的折彎角度和形狀。在這個過程中，各軸的精確運(yùn)動和機(jī)械工作臺補(bǔ)償機(jī)制共同作用，保證了折彎的準(zhǔn)確性和一致性 。

5. 數(shù)控系統(tǒng)的核心作用：數(shù)控系統(tǒng)是整個折彎機(jī)的大腦，它不僅負(fù)責(zé)接收和處理操作人員輸入的各種加工參數(shù)，還能對電液伺服系統(tǒng)、各軸的運(yùn)動以及機(jī)械工作臺補(bǔ)償裝置等進(jìn)行實(shí)時監(jiān)控和精確控制。通過內(nèi)置的算法和程序，數(shù)控系統(tǒng)能夠根據(jù)不同的加工任務(wù)，自動調(diào)整各部分的工作狀態(tài)，實(shí)現(xiàn)自動化、智能化的折彎加工過程，同時還具備故障診斷、數(shù)據(jù)記錄和存儲等功能，方便操作人員進(jìn)行設(shè)備維護(hù)和生產(chǎn)管理。

     The working principle of the HTB(G)-DA69W series 8 + 1-axis electro-hydraulic servo CNC press brake with mechanical worktable compensation integrates multi-axis linkage control, electro-hydraulic servo drive, and a unique mechanical worktable compensation mechanism, as follows:

1. Principle of Electro-hydraulic Servo Drive: This press brake adopts an advanced electro-hydraulic servo system. The CNC system will send corresponding electrical signals to the electro-hydraulic servo valve after precise calculation and analysis based on the processing parameters pre-entered by the operator (such as the material, thickness, bending angle, and bending length of the sheet metal, etc.). The electro-hydraulic servo valve precisely controls the flow and direction of the hydraulic oil according to these electrical signals, and then drives the hydraulic cylinder to achieve precise control of the movement of the slider, including the descending speed, stop position, and the applied pressure of the slider, to ensure the accuracy and stability of the bending operation.

2. 8 + 1-axis Linkage Control: "8 + 1-axis" means that this press brake has multiple axes that can move independently and work in coordination. Among them, the 8 axes usually include the vertical movement axis of the slider (controlling the up-and-down stroke to achieve the bending action), multiple positioning axes of the backgauge (used to accurately determine the position of the sheet metal to ensure the dimensional accuracy of each bending), etc. The additional 1 axis may refer to a specific auxiliary axis or an axis with special functions. Under the coordination and control of the CNC system, these axes can perform linkage movements according to the preset program and trajectory, enabling the press brake to handle various complex bending tasks and meet the processing requirements of sheet metals of different shapes and sizes.

3. Principle of Mechanical Worktable Compensation: During the bending process, the worktable will deform to a certain extent due to the large pressure it bears, and this deformation will affect the bending accuracy. To overcome this problem, this press brake is equipped with a mechanical worktable compensation device. When the slider moves downward to apply pressure to the sheet metal for bending, the deformation of the worktable will be monitored in real time by the detection device (possibly through sensors and other equipment). The CNC system calculates the required compensation amount according to the detected deformation data and controls the mechanical compensation device (such as through a screw and nut mechanism, etc.) to make fine adjustments to the corresponding parts of the worktable, increasing or decreasing the local height of the worktable, thereby compensating for the bending error caused by the deformation of the worktable, ensuring the high accuracy of the bending angle and dimensions, and improving the processing quality.

4. Mold Matching and Bending Process: Specific-shaped and sized upper and lower molds are installed on the press brake. The upper mold is fixed on the slider, and the lower mold is installed on the worktable. When the slider moves downward driven by the electro-hydraulic servo system, the sheet metal is placed between the upper and lower molds. As the slider continues to press down, the sheet metal undergoes plastic deformation under the action of the molds and gradually reaches the required bending angle and shape. During this process, the precise movement of each axis and the mechanical worktable compensation mechanism work together to ensure the accuracy and consistency of the bending. 

5. The Core Role of the CNC System: The CNC system is the brain of the entire press brake. It is not only responsible for receiving and processing various processing parameters input by the operator but also for real-time monitoring and precise control of the electro-hydraulic servo system, the movement of each axis, and the mechanical worktable compensation device, etc. Through the built-in algorithms and programs, the CNC system can automatically adjust the working status of each part according to different processing tasks to achieve an automated and intelligent bending processing process. At the same time, it also has functions such as fault diagnosis, data recording, and storage, which is convenient for the operator to carry out equipment maintenance and production management.

I. Equipment Features:

This machine tool is equipped with the imported Dutch DELEM DA69W CNC system or the Swiss CYBELEC system.

It has a user-friendly boom. Based on the real-time Windows operating system, it is a three-dimensional color graphic CNC system for press brakes.

The adoption of the Dutch DELEM DA69W CNC system or the Swiss CYBELEC press brake CNC system provides users with a friendly operation interface, a high-efficiency programming method, and integrates the proud stability, which will greatly improve the working efficiency of the CNC press brake.

The CNC system includes 2D graphic programming software, which has functions such as automatic calculation of bending processes, workpiece interference detection, and a self-learning database. The application of the database will greatly improve the bending accuracy.

The full-featured 3D graphic programming software clearly shows the configuration of the real machine tool mold and the feasibility of bending.

A more efficient algorithm is used to optimize the entire working cycle of the Y-axis, X-axis, R-axis, and compensation V-axis, shortening the cycle period of the Y-axis, X-axis, R-axis, and compensation V-axis, improving the working efficiency of the machine tool.
