壓住材料。克服傳統(tǒng)的模具設(shè)計結(jié)構(gòu)，在卸料板上開出容料間隙(即模具閉合時，卸料板與凹模貼合，而容納材料處卸料板與凹模的間隙為材料厚t-0.03～0.05mm)。如此，沖壓中卸料板運動平穩(wěn)，而材料又可被壓緊。關(guān)鍵成形部位，卸料板一定做成鑲塊式結(jié)構(gòu)，以方便解決長時間沖壓所導(dǎo)致卸料板壓料部位產(chǎn)生的磨(壓)損，而無法壓緊材料。

Press the material. In order to overcome the traditional mold design structure, the clearance of material is opened on the discharge plate (i.e., when the die is closed, the discharge plate and the die are fitted, and the gap between the discharge plate and the die is t-0.03 to 0.05mm). In this way, the discharging plate moves smoothly, and the material can be pressed tightly. In the key forming part, the discharge plate must be made into an inlaid structure to facilitate the solution of the grinding (pressure) loss caused by the pressing part of the unloading plate for a long time, and the material can not be pressed.

沖壓件是靠壓力機和模具對板材、帶材、管材和型材等施加外力，使之產(chǎn)生塑性變形或分離，從而獲得所需形狀和尺寸的工件（沖壓件）的成形加工方法。沖壓和鍛造同屬塑性加工（或稱壓力加工），合稱鍛壓。

Stamping is a forming and processing method for workpiece (stamping parts) by applying external force to plate, strip, pipe and profile by press and die to produce plastic deformation or separation. Stamping and forging belong to plastic processing (or pressure machining).

五金沖壓模具的安裝是否正確合理，不僅影響五金沖壓件的產(chǎn)品質(zhì)量和精度，還會影響模具的工作壽命及生產(chǎn)安全。并且熟練掌握沖壓模具的安裝也是每個沖壓工應(yīng)該掌握的技巧。

Whether the installation of the metal stamping die is correct and reasonable, not only affects the quality and precision of the metal stamping parts, but also affects the working life and production safety of the die. And skilled in stamping die installation is also a skill that every stamping worker should master.
