手板设计是提高手板质量的重要一步，需要考虑素需要考虑，如手板材料的选择、手板结构的可用性和性、手板零件的可加工性和手板维护的便利性。接下来，济南手板加工厂小编将告诉您制定手板模型的五大注意点。

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）制定手板工艺路线，可根据工件需要分为两次加工。加工手板的外观和内壁，铣削基准，然后翻转180。夹紧，加工外表面和关键屏幕位置。如果外表面先加工，再加工内壁，则很难定位夹具进行二次加工。

(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，加工外表面时容易变形破碎。如果在加工过的型腔中添加填料作为支撑。这样可以避免加工出口，然后填充石膏，否则成品和填料很难分离。

(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）先修复修剪曲面，覆盖表面通孔位置，进行整体加工，然后在开槽处完成通孔加工，避免刀路起伏不平稳，切削力不均匀。

(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)记住！先铣出基准截角，以免翻转夹子时胚料调整方向错误。

(4) Remember! First, mill out the datum angle to avoid the wrong direction of blank adjustment when turning the clamp.

(5)注意:在生产过程中，先模拟切割，检查正确后再处理，进行数控加工。

(5) Note: In the production process, simulate cutting first, check the correctness before processing, and then conduct numerical control processing.

此外手板材料的选择不仅要满足客户对产品质量的要求，还要考虑设定周期内材料的成本和强度。当然，材料应根据手板的类型、工作方法、加工速度、主要故障形式等因素进行选择。

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，冲压模具的主要故障形式是刃口磨损，应选择表面硬度高、耐磨性好的材料；冲压模具主要承受周期载荷，容易引起表面疲劳裂纹，导致表面剥落，应选择表面韧性好的材料；应选择摩擦系数特别低的材料；由于循环热应力，应选择热疲劳性强的材料。

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.

手板上的各种部件应具有足够的强度和刚度，以防止使用过程中的损坏和变形。紧固件应采取防松动措施，以避免意外伤害操作人员。更多关于手板制作或者加工的注意事项就来我们网站http://www.metferro.com进行咨询了解吧！

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.
