深縫：鋸削深縫時即當(dāng)鋸縫的深度超過鋸弓高度時，高度時，鋸弓就會與工具相碰，無法繼續(xù)鋸削；此時應(yīng)將鋸條拆出，將鋸條轉(zhuǎn)90。

Deep seam: when sawing deep seams, when the depth of the sawblade exceeds the height of the saw bow, when the height is high, the saw bow is touched by the tool and can not continue to be sawed; the saw strip should be removed and the saw blade is turned 90.

手鋸鋸削的注意事項(xiàng)

鋸條的松緊要合適，且鋸割時壓力不能太大，以防折斷傷人；

當(dāng)鋸縫歪斜時，不可急于糾正，而需要慢慢地逐步糾正。

Notice of hand saw cutting

The tightness of the saw blade should be suitable, and the pressure should not be too large during sawing, so as to prevent breaking and hurting people.

When the SAW seam is skewed, it can not be corrected in a hurry, but it needs to be corrected gradually.

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.
