在制作手板之前對手板進(jìn)行設(shè)計對于提高手板質(zhì)量是非常重要的，實際手板需要考慮到很多因素，如：手板材料的選用、手板結(jié)構(gòu)的可使用性及性、手板零件的可加工性及手板維修的方便性，這些在設(shè)計手板之初都應(yīng)當(dāng)盡量考慮得周全一些。下面就來講講濟(jì)南手板模型制作的注意事項。

It is very important to design the hand board before making the hand board to improve the quality of the hand board. The actual hand board needs to consider many factors, such as the selection of hand board materials, the usability and safety of the hand board structure, the processability of the hand board parts, and the convenience of the hand board maintenance. These should be considered as comprehensive as possible at the beginning of the design of the hand board. Now let's talk about the notes for making the prototype in Jinan.

一、手板材料的選用

1、 Selection of hand board materials

手板材料的選用既要滿足客戶對產(chǎn)品質(zhì)量的要求，還應(yīng)當(dāng)考慮到材料的成本及其在設(shè)計周期內(nèi)的強(qiáng)度，同時還需根據(jù)手板的類型、使用的工作方式、加工速度、主要失效形式等因素來選擇。

The selection of prototype materials should not only meet the customer's requirements for product quality, but also take into account the cost of materials and their strength in the design cycle. At the same time, it should also be selected according to the type of prototype, working mode, processing speed, main failure forms and other factors.

例如：

For example:

沖裁模的主要失效形式是刃口磨損，就需選擇表面硬度高、耐磨性好的材料；沖壓模主要承受周期性載荷，易引起表面疲勞裂紋，導(dǎo)致表面剝落，就要選擇表面韌性好的材料；拉伸模應(yīng)選擇摩擦系數(shù)特別低的材料；壓鑄模由于受到循環(huán)熱應(yīng)力作用，故應(yīng)選擇熱疲勞性強(qiáng)的材料。

The main failure form of blanking die is edge wear, so it is necessary to select materials with high surface hardness and good wear resistance; Stamping die mainly bears periodic load, which is easy to cause surface fatigue cracks and surface peeling, so it is necessary to select materials with good surface toughness; The material with particularly low friction coefficient shall be selected for the drawing die; Because the die-casting die is subjected to cyclic thermal stress, the material with strong thermal fatigue should be selected.

二、手板制作加工時的注意事項

2、 Precautions during the production and processing of hand boards

1.手板工藝路線制定可先按照工件需要分兩次加工。先加工手板的外觀內(nèi)壁，銑好基準(zhǔn)，再翻轉(zhuǎn)180度裝夾，加工外表面及按鍵屏幕位置。若先加工外表面，再加工內(nèi)壁，則難以定位裝夾進(jìn)行二次加工。

1. The manual process route can be prepared in two times according to the needs of the workpiece. First, process the exterior inner wall of the hand board, mill the benchmark, then turn over the 180 degree clamp, and process the exterior surface and key screen position. If the outer surface is processed first and then the inner wall is processed, it is difficult to position and clamp for secondary processing.

2.如果手板的壁厚只有1.5mm，加工外表面時易出現(xiàn)變形、破碎的現(xiàn)象。如有在已加工好的型腔中加入填充物做出支撐。這樣可避免加工出通孔部位，再填充石膏，否則很難分離成品和填充物。

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 any, add filler to the machined cavity for support. In this way, it can avoid processing through holes and filling gypsum, otherwise it is difficult to separate finished products and fillers.

3.要先修復(fù)修剪的曲面，掩蓋住表面通孔位置，進(jìn)行正面加工，然后再進(jìn)行挖槽完成通孔加工，以免加工到通孔部位加工時刀路起伏不順暢，切削力不均勻等現(xiàn)象。

3. The trimmed surface shall be repaired first to cover the position of the surface through hole, and then the front face shall be machined, and then the through hole shall be finished by slotting, so as to avoid such phenomena as unsmooth tool path fluctuation and uneven cutting force when machining to the through hole.

4.切記！要先銑出基準(zhǔn)截角，以免翻轉(zhuǎn)裝夾時配料調(diào)錯方向。

4. Remember! The datum angle shall be milled first to avoid the wrong direction of batching during overturning and clamping.

5.需要注意的是，制作過程中要先模擬切削，檢查無誤后，再進(jìn)行處理，進(jìn)行人數(shù)控加工。

5. It should be noted that during the manufacturing process, the cutting shall be simulated first, and then the processing shall be carried out after no error is found.

手板上的各種零件應(yīng)有足夠的強(qiáng)度及剛度，防止使用過程中損壞和變形，手板上的各種零件應(yīng)有足夠的強(qiáng)度及剛度，防止使用過程中損壞和變形，緊固零件要有防松動措施，避免意外傷害操作者。不允許在加工過程中發(fā)生廢料或工件飛彈現(xiàn)象，影響操作者的注意力，甚擊傷操作者。另外要避免沖裁件毛刺割傷人手。更多注意事項就來我們網(wǎng)站http://www.faxuemingjia.com咨詢了解吧。

The various parts on the hand board shall have sufficient strength and stiffness to prevent damage and deformation during use. The various parts on the hand board shall have sufficient strength and stiffness to prevent damage and deformation during use. The fastening parts shall have anti loosening measures to avoid accidental injury to the operator. It is not allowed to produce waste materials or workpiece missiles during processing, which may affect the operator's attention or even injure the operator. In addition, avoid cutting hands by burrs of blanking parts. More notes on our website http://www.faxuemingjia.com Ask and understand.
