制定手板模型的五大注意點

手板設(shè)計是提高手板質(zhì)量的重要一步，需要考慮素需要考慮，如手板材料的選擇、手板結(jié)構(gòu)的可用性和性、手板零件的可加工性和手板維護(hù)的便利性。接下來，濟(jì)南手板加工廠小編將告訴您制定手板模型的五大注意點。
Prototype design is an important step to improve the quality of the prototype, which needs to be considered, such as the selection of prototype materials, the availability and safety of prototype structure, the processability of prototype parts, and the convenience of prototype maintenance. Next, Xiao Bian of Jinan Prototype Processing Factory will tell you the five points for attention in developing the prototype.
（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) The manual process route can be divided into two processes according to the needs of the workpiece. First, process the appearance and inner wall of the hand board, mill the benchmark, and then turn 180. Clamping, machining external surfaces and key screen positions. If the outer surface is processed first and then the inner wall is processed, it is difficult to position the fixture for secondary processing.
(2)如果手板的壁厚只有1.5mm，加工外表面時容易變形破碎。如果在加工過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 be deformed and broken when processing the external surface. If packing is added to the machined cavity as a support. This can avoid processing the export and then filling the gypsum, otherwise it is difficult to separate the finished product from the filler.
（3）先修復(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) First, repair and trim the surface, cover the through hole position on the surface, and perform the overall processing. Then, complete the through hole processing at the slot to avoid uneven tool path fluctuation and cutting force.
(4)記住！先銑出基準(zhǔn)截角，以免翻轉(zhuǎn)夾子時胚料調(diào)整方向錯誤。
(4) Remember! First, mill out the datum angle to avoid the wrong direction of blank adjustment when turning the clamp.
(5)注意:在生產(chǎn)過程中，先模擬切割，檢查正確后再處理，進(jìn)行數(shù)控加工。
(5) Note: In the production process, simulate cutting first, check the correctness before processing, and then conduct numerical control processing.
此外手板材料的選擇不僅要滿足客戶對產(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。
In addition, the selection of prototype materials should not only meet the customer's requirements for product quality, but also consider the cost and strength of materials in the set cycle. Of course, the materials shall be selected according to the type, working method, processing speed, main fault form and other factors of the hand board.
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 failure form of stamping die is edge wear, so materials with high surface hardness and good wear resistance should be selected; Stamping die mainly bears periodic load, which is easy to cause surface fatigue cracks and lead to surface peeling. Materials with good surface toughness should be selected; Materials with very low friction coefficient shall be selected; Due to cyclic thermal stress, materials with strong thermal fatigue should be selected.
手板上的各種部件應(yīng)具有足夠的強(qiáng)度和剛度，以防止使用過程中的損壞和變形。緊固件應(yīng)采取防松動措施，以避免意外傷害操作人員。更多關(guān)于手板制作或者加工的注意事項就來我們網(wǎng)站http://www.xtgs.com.cn進(jìn)行咨詢了解吧！
Various components on the hand board shall have sufficient strength and stiffness to prevent damage and deformation during use. Anti loosening measures shall be taken for fasteners to avoid accidental injury to operators.
