手板生產(chǎn)加工需要注意5點(diǎn)

手板材料的選擇不僅要滿足客戶對(duì)產(chǎn)品質(zhì)量的要求，還要考慮設(shè)定周期內(nèi)材料的成本和強(qiáng)度。當(dāng)然，材料應(yīng)根據(jù)手板的類型、工作方法、加工速度、主要故障形式等因素進(jìn)行選擇。
The selection of hand board materials should not only meet the customer's requirements for product quality, but also consider the cost and strength of the materials within the set cycle. Of course, materials should be selected based on factors such as the type of hand board, working method, processing speed, and main failure modes.
例如，沖壓模具的主要故障形式是刃口磨損，應(yīng)選擇表面硬度高、耐磨性好的材料；沖壓模具主要承受周期載荷，容易引起表面疲勞裂紋，導(dǎo)致表面剝落，應(yīng)選擇表面韌性好的材料；應(yīng)選擇摩擦系數(shù)特別低的材料；由于循環(huán)熱應(yīng)力，應(yīng)選擇熱疲勞性強(qiáng)的材料。
For example, the main form of failure in stamping molds is blade wear, and materials with high surface hardness and good wear resistance should be selected; Stamping molds mainly bear cyclic loads, which can easily cause surface fatigue cracks and surface peeling. Therefore, materials with good surface toughness should be selected; Materials with particularly low friction coefficients should be selected; Due to cyclic thermal stress, materials with strong thermal fatigue should be selected.
濟(jì)南手板生產(chǎn)加工需要注意以下幾點(diǎn)：
The production and processing of hand boards in Jinan should pay attention to the following points:
（1）制定手板工藝路線，可根據(jù)工件需要分為兩次加工。加工手板的外觀和內(nèi)壁，銑削基準(zhǔn)，然后翻轉(zhuǎn)180。夾緊，加工外表面和關(guān)鍵屏幕位置。如果外表面先加工，再加工內(nèi)壁，則很難定位夾具進(jìn)行二次加工。
(1) Develop a handicraft process route that can be divided into two processing steps according to the needs of the workpiece. Firstly, process the appearance and inner wall of the hand board, milling the benchmark, and then flip it 180 degrees. Clamping, machining the outer surface and key screen positions. If the outer surface is processed first and then the inner wall, it will be difficult to position the fixture for secondary processing.
(2)如果手板的壁厚只有1.5mm，加工外表面時(shí)容易變形破碎。如果在加工過(guò)的型腔中添加填料作為支撐。這樣可以避免加工出口，然后填充石膏，否則成品和填料很難分離。
(2) If the wall thickness of the hand board is only 1.5mm, it is easy to deform and break when processing the outer surface. If filler is added as a support in the processed cavity. This can avoid processing exports and then filling with gypsum, otherwise it is difficult to separate the finished product and filler.
（3）修復(fù)修剪曲面，覆蓋表面通孔位置，進(jìn)行整體加工，然后在開(kāi)槽處完成通孔加工，避免刀路起伏不平穩(wěn)，切削力不均勻。
(3) Firstly, repair and trim the surface, cover the through-hole position on the surface, and perform overall machining. Then, complete through-hole machining at the slot to avoid uneven tool path fluctuations and cutting forces.
(4)記住！先銑出基準(zhǔn)截角，以免翻轉(zhuǎn)夾子時(shí)胚料調(diào)整方向錯(cuò)誤。
(4) Remember! First, mill out the reference intercept to avoid the wrong direction of adjusting the blank when flipping the clamp.
(5)注意:在生產(chǎn)過(guò)程中，先模擬切割，檢查正確后再處理，進(jìn)行數(shù)控加工。
(5) Attention: During the production process, simulate cutting first, check for correctness, and then proceed with CNC machining.
手板上的各種部件應(yīng)具有足夠的強(qiáng)度和剛度，以防止使用過(guò)程中的損壞和變形。緊固件應(yīng)采取防松動(dòng)措施，以避免意外傷害操作人員。廢物或工件在加工過(guò)程中不得飛行，影響操作人員的注意力，甚傷害操作人員。此外，避免切割部件的毛刺。還有什么事項(xiàng)就來(lái)我們網(wǎng)站http://www.ebook5.cn咨詢！
The various components on the hand board should have sufficient strength and stiffness to prevent damage and deformation during use. Fasteners should take anti loosening measures to avoid accidental injury to operators. Waste or workpieces must not fly during the processing, affecting the attention of operators and even harming them. In addition, avoid burrs on cutting components.
