埃馬克生產(chǎn)系統(tǒng)：
適合差速器外殼的高效加工解決方案
Production system by EMAG:
High-performance solutions for differential cases
根據(jù)麥肯錫公司最新的一項調研預測，至 2030 年，全球汽車產(chǎn)量的年增長率為百分之二。以差動傳動裝置為例，如何在保證達到高質量要求的同時，也滿足日益增加的產(chǎn)量要求：無論使用何種驅動系統(tǒng)設計，該核心組件均必不可少。換言之，差速器殼體的產(chǎn)量將持續(xù)增加。同時，差速器外殼的加工要求也極其嚴格。埃馬克集團在這個領域中已處于優(yōu)勢地位：這家專業(yè)制造商研發(fā)包括倒立式車削中心、工件輸送系統(tǒng)解決方案和夾具在內的完整生產(chǎn)線，從而能為用戶提供差速器外殼的高效加工整體交鑰匙解決方案。
The worldwide production of motor vehicles is set to rise by about two percent every year until 2030, according to the estimates of a new McKinsey study. An excellent example of how to handle these rising production volumes despite stringent quality requirements can be found in the differential: This key component will remain indispensable whatever the propulsion system used by the vehicle. In other words, production volumes of differentials will continue to rise. At the same time, the machining required for parts like the differential case can be very demanding. The EMAG Group is well positioned in this environment: Its specialists develop complete production lines including vertical turning centers, automation solutions, and clamping devices. The user receives a turnkey, high-performance production solution for differential cases.
在汽車制造行業(yè)中，差速器殼體始終是生產(chǎn)規(guī)劃人員關注的重點。一方面，無論汽車使用內燃機、電動機還是混合動力發(fā)動機進行驅動：過彎時用于平衡兩個車輪之間轉速的車橋差速器總是不可或缺的。另一方面，工件種類繁多，并且全部需要高效可靠地進行生產(chǎn)。以差速器外殼為例：差速器外殼有內部為球形或半球形的封閉式殼體，也有配備蓋子的“開放式”殼體，這些不同的形狀會影響加工工序。但無論是哪種情況，都需要分為多道相互協(xié)調、依次執(zhí)行的子工序進行加工。設計制造此類整體系統(tǒng)便是總部位于薩拉赫的埃馬克集團這樣的專業(yè)制造商的任務。“我們?yōu)楦鞣N差速器外殼的加工研發(fā)完整的解決方案。方案中所采用的工藝技術，包括倒立式車削中心、夾具和連線裝置，均來自埃馬克。客戶可向埃馬克中心聯(lián)系人一對一提出所有要求，然后將整個項目規(guī)劃工作外包給我們。我們可以為客戶提供經(jīng)過完美協(xié)調的整體式系統(tǒng)——節(jié)拍僅 95 秒、場地需求小、工藝可靠性高，”埃馬克的模塊化解決方案技術銷售經(jīng)理兼差速器外殼技術專家 Daniele Loporchio 解釋說。
The differential case is still a constant focus of attention among production planners in the automotive industry. For one, it doesn't matter whether the vehicle is powered by a combustion engine, an electric motor, or a hybrid engine: They all require an axle differential that compensates the speed between the two wheels during turns. On top of that, there are different versions of the component that all need to be manufactured efficiently and reliably. Take the differential case, for example: There are closed cases with a spherical or hemispherical internal shape, and “open” cases with a lid. These shapes have an effect on the machining sequence. In all cases, however, a number of subprocesses are required which need to be carried out in a perfectly timed sequence cycle. Creating an overall system that can do this is a job for specialists—like the EMAG Group based in Salach, Germany. “We develop comprehensive solutions for machining different types of differential cases. EMAG supplies all the technology required, including vertical turning centers, clamping devices, and interlinking of machines. Customers discuss their requirements with a single point of contact and outsource the entire project planning to us. The result is a perfectly calibrated comprehensive system with short cycle times of only about 95 seconds, a small footprint, and high process reliability,” explains Daniele Loporchio, Technical Sales Manager Modular Solutions and technology expert for differential cases at EMAG.
四道工序、節(jié)拍僅 95 秒即可達成目標
埃馬克展示的差速器外殼制造系統(tǒng)以其簡單而巧妙的設計令人印象深刻。為能實現(xiàn)這一節(jié)拍僅為 95 秒的完整加工工序，各機床無一例外地采用了埃馬克的模塊化解決方案，并與 TrackMotion 工件輸送系統(tǒng)高效聯(lián)接。
OP 10 / OP 20：車削差殼面一側 / 法蘭面一側
差殼首先在兩臺 VL 4 車床上進行加工。此處將完成軸座和法蘭的內部和外部加工。VL 機床配備具有 12 個刀位的動力刀具刀塔，還可實現(xiàn)十字軸孔鉆削加工。
OP 30：車削外徑
差速器外殼的剩余外部加工可在一臺 VT 4 車床上通過一次裝夾完成。由此可排除重復裝夾定位帶來的裝夾誤差。VT 4 配備兩個刀塔，每個刀塔具有 11 個刀位。由此可實現(xiàn) 4 軸同時加工，從而縮短節(jié)拍。工件的平行上下料也確保縮短非加工時間。
OP 40：精加工
后續(xù)加工在一臺 VL 6立式車削中心上進行。在 OP 40 中，埃馬克專為差速器外殼加工而設計的獨特夾具(見圖示)是一大亮點。在這道工序中對十字軸孔進行精鉸加工，并用鵝頸刀對球頂先進行粗加工，然后再進行精加工——全部在一次裝夾中完成。
至此僅需要完成最后的質檢步驟。此步驟可在一套額外的測量系統(tǒng)上完成，確保每件差速器外殼均具有完美的品質。
Job done in four operations with a cycle time of only 95 seconds
What is striking about the manufacturing system for differential cases that EMAG is presenting is its simple and yet ingenious design. To implement such comprehensive machining within a cycle time of only about 95 seconds, the machines used are exclusively based on EMAG Modular Solutions building blocks that are interlinked with the TrackMotion automation system.
OP 10 / OP 20: TURNING OF THE CASE SIDE / FLANGE SIDE
The case is first machined on two VL 4 turning centers. This is where the internal and external machining of the shaft mounts and flanges is performed. Furthermore, the driven tool turret with 12 tool posts on the VL machines enables them to drill cross holes.
OP 30: TURNING OF THE OUTER DIAMETER
The remaining external machining of the differential case is performed with a single clamping operation on a VT 4 turning center. This eliminates the occurrence of positioning errors when changing the clamping position. The VT 4 has two tool turrets with 11 tool posts each, which enables 4-axis simultaneous machining and thus quick processes. Moreover, parallel loading and unloading of components ensures short idle times.
OP 40: FINE MACHINING AND FINISHING
Machining is then performed on a VL 6 pick-up turning center. In OP 40, the imposing clamping device catches the eye. It was specially developed by EMAG to machine differential cases (see image). In this operation, the bore holes are precision machined and the spherical calotte is first rough-machined on the inside with a special tool and then finished—all in a single clamping operation.
All that remains to be done now is final quality control. This is performed on an additional measuring system and thus guarantees that each differential case is of flawless quality.
此外，這套系統(tǒng)的連線也非常高效。基于埃馬克的模塊化和標準化機床平臺：由于具有統(tǒng)一的傳送高度、軟件控制系統(tǒng)和上下料主軸，可以輕松地使用埃馬克的 TrackMotion 工件輸送系統(tǒng)來連接各臺機床。配備可編程電動機械手的升降翻轉滑臺可在各臺機床之間的軌道 (Track) 上來回穿梭，并將差速器外殼放置到輸送帶上。之后，由上下料工作主軸將工件送入和送出加工區(qū)——這是一個非加工時間極短的快速進程。還有很重要的一點，由于采用緊湊型的立式機床，整條生產(chǎn)線的占地面積非常小，可輕松訪問及設置各個模塊。
The interlinking of the machines in this system is also especially effective. It is based on EMAG's modular, standardized machine platform: With their uniform transfer height, software control, and pick-up spindle, the machines can easily be connected using EMAG's TrackMotion automation system. A lifting and flip-over carriage with a programmable electric gripper runs back and forth between the machines on a track and places the differential cases on a conveyor belt. The pick-up working spindle then transports the parts in and out of the machining area, in a rapid process with little non-productive time. Owing to the compact vertical machines, the overall line has a very small footprint, and the modules can be accessed easily for setup.
在市場上取得成功
近年來，這種精簡高效的生產(chǎn)方法越來越成功：在全球范圍內，已有 60 至 70 條埃馬克生產(chǎn)線、共約 250 臺機床應用于差速器外殼的車削生產(chǎn)。原始設備制造商和一級供應商均信賴這種工藝技術。“我們提供從機床到夾具的整套交鑰匙產(chǎn)品。所有組件都已完美協(xié)調匹配。我們所有的研發(fā)工作都以豐富的實踐經(jīng)驗為基礎，這些優(yōu)勢將在市場上得到認可，”Loporchio 總結說。
Successful in the marketplace
In recent years, this slim and efficient approach has enjoyed ever greater success: 60 to 70 EMAG production lines with a total of around 250 turning machines are already in use around the world in the production of differential cases. OEMs and tier 1 suppliers rely on this technology. “We offer the complete package, from machine to clamping device. All the components are perfectly matched. Also, all our development work is grounded in a lot of practical experience. These advantages are gaining recognition in the marketplace,” says Loporchio in conclusion.
