在制作手板之前对手板进行设计对于提高手板质量是非常重要的，实际手板需要考虑到很多因素，如：手板材料的选用、手板结构的可使用性及性、手板零件的可加工性及手板维修的方便性，这些在设计手板之初都应当尽量考虑得周全一些。下面就来讲讲济南手板模型制作的注意事项。

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、手板材料的选用

1、 Selection of hand board materials

手板材料的选用既要满足客户对产品质量的要求，还应当考虑到材料的成本及其在设计周期内的强度，同时还需根据手板的类型、使用的工作方式、加工速度、主要失效形式等因素来选择。

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:

冲裁模的主要失效形式是刃口磨损，就需选择表面硬度高、耐磨性好的材料；冲压模主要承受周期性载荷，易引起表面疲劳裂纹，导致表面剥落，就要选择表面韧性好的材料；拉伸模应选择摩擦系数特别低的材料；压铸模由于受到循环热应力作用，故应选择热疲劳性强的材料。

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、手板制作加工时的注意事项

2、 Precautions during the production and processing of hand boards

1.手板工艺路线制定可先按照工件需要分两次加工。先加工手板的外观内壁，铣好基准，再翻转180度装夹，加工外表面及按键屏幕位置。若先加工外表面，再加工内壁，则难以定位装夹进行二次加工。

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，加工外表面时易出现变形、破碎的现象。如有在已加工好的型腔中加入填充物做出支撑。这样可避免加工出通孔部位，再填充石膏，否则很难分离成品和填充物。

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.要先修复修剪的曲面，掩盖住表面通孔位置，进行正面加工，然后再进行挖槽完成通孔加工，以免加工到通孔部位加工时刀路起伏不顺畅，切削力不均匀等现象。

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.切记！要先铣出基准截角，以免翻转装夹时配料调错方向。

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，制作过程中要先模拟切削，检查无误后，再进行处理，进行人数控加工。

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.

手板上的各种零件应有足够的强度及刚度，防止使用过程中损坏和变形，手板上的各种零件应有足够的强度及刚度，防止使用过程中损坏和变形，紧固零件要有防松动措施，避免意外伤害操作者。不允许在加工过程中发生废料或工件飞弹现象，影响操作者的注意力，甚击伤操作者。另外要避免冲裁件毛刺割伤人手。更多注意事项就来我们网站http://www.metferro.com咨询了解吧。

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.metferro.com Ask and understand.
