設(shè)計(jì)的沖壓件必須形狀簡(jiǎn)單，結(jié)構(gòu)合理，以有利于簡(jiǎn)化模具結(jié)構(gòu)、簡(jiǎn)化工序數(shù)量，即用少、簡(jiǎn)單的沖壓工序完成整個(gè)零件的加工，減少再用其他方法加工，并有利于沖壓操作，便于組織實(shí)現(xiàn)機(jī)械化與自動(dòng)化生產(chǎn)，以高勞動(dòng)生產(chǎn)率。

設(shè)計(jì)的沖壓件，在保證能正常使用情況下，盡量使尺寸精度等級(jí)及表面粗糙度等級(jí)要求低一些，并有利于產(chǎn)品的互換，減少?gòu)U品、保證產(chǎn)品質(zhì)量穩(wěn)定。

設(shè)計(jì)的沖壓件，應(yīng)有利于盡可能使用現(xiàn)有設(shè)備、工藝裝備以及工藝流程對(duì)其進(jìn)行加工，并有利于沖模使用壽命的延長(zhǎng)。

五金沖壓件材料的硬度檢測(cè)，其主要目的就是確定購(gòu)入的金屬板材退火程度是否適于隨后將要進(jìn)行的沖壓件加工，不同種類的沖壓件加工工藝，需要不同硬度級(jí)別的板材。

stamping material hardness testing, the main is to determine whether the purchase of metal sheet annealing is suitable for subsequent stamping parts processing, different types of stamping processing technology, the need for different hardness levels of the plate.

增設(shè)強(qiáng)壓功能。即對(duì)卸料鑲塊壓料部加厚尺寸(正常的卸料鑲塊厚H 0.03mm)，以增加對(duì)凹模側(cè)材料的壓力，從而抑制沖切時(shí)沖壓件產(chǎn)生翻料、扭曲變形。

Additional pressure function. In order to increase the pressure on the material of the die side, the pressure of the material in the die side is increased by the thickness of the material of the unloaded insert (normal unloaded insert thickness H 0.03mm), so as to suppress the turning and distortion of the stamping parts.

薄板：鋸削時(shí)盡可能從寬面鋸下去，若必須從窄面鋸下時(shí)，可用兩塊木墊夾持，連木塊一起鋸下，也可把薄板直接夾在虎鉗上，用手鋸作橫向斜推鋸，使鋸齒與薄板料接觸的齒數(shù)增加，避免鋸齒崩裂。

Thin plate: sawing as far as  as wide as when sawing. If must be sawed from narrow surface, it can be held by two wooden blocks and sawed together with wooden blocks. The sheet can be clipped directly to the vise, and a hand saw is used as a transverse oblique saw to increase the number of teeth contacted with the sheet material and avoid the crack of the saw teeth.
