五金沖壓件與鑄件、鍛件相比，具有薄、勻、輕、強(qiáng)的特點。沖壓可制出其他方法難于制造的帶有加強(qiáng)筋、肋、起伏或翻邊的工件，以提高其剛性。秦皇島五金沖壓件由于采用精密模具，工件精度可達(dá)微米級，且重復(fù)精度高、規(guī)格一致，可以沖壓出孔窩、凸臺等。冷沖壓件一般不再經(jīng)切削加工，或僅需要少量的切削加工。熱沖壓件精度和表面狀態(tài)低于冷沖壓件，但仍優(yōu)于鑄件、鍛件，切削加工量少。

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.

檢查、核對模具和沖壓機(jī)床。在安裝模具前，要確認(rèn)沖壓機(jī)床為沖壓工藝的型號，并檢查模具的尺寸、工作要求是否與沖壓機(jī)床的技術(shù)參數(shù)（裝模高度、滑塊行程等）相匹配，沖壓機(jī)床的狀態(tài)足否良好。

Check and check die and stamping machine. Before installing the mould, it is necessary to confirm that the stamping machine is the designated type of the stamping process, and check the size of the die and the work requirements to match the technical parameters of the designated stamping machine (the height of the die, the slider stroke, etc.), and the state of the stamping machine is good or not.

將閉合的模具放置于雎力機(jī)工作臺或墊板上適當(dāng)位置，如果使用氣墊，先要放好頂桿，并標(biāo)記好模具的擺放位置。

手動扳動沖壓機(jī)床飛輪（或操縱點動按鈕），使機(jī)床上滑塊下行并停于下死點位置。

Place the closed mould on the bench or pad of the mandrel machine. If the air cushion is used, the ejector pin should be placed first and the placement of the mould should be marked.

Manually pull the flywheel of the stamping machine (or  the moving button), so that the slider on the machine tool will be downhill and stop at the bottom dead center.
