選擇釘箱機時應該注意哪些技術參數？
    在選購這類機(ji)器時主要是看廠家的(de)釘頭、機(ji)身加工材質以及(ji)處理工藝和(he)裝配水(shui)平(ping)。釘箱機(ji)的(de)技術(shu)參數：

    普(pu)通(tong)手(shou)動(dong)(dong)釘(ding)(ding)箱機(ji)(ji)的(de)結(jie)構為：主要(yao)有(you)釘(ding)(ding)頭(tou)(tou)(tou)、托臂、驅動(dong)(dong)電(dian)(dian)(dian)機(ji)(ji)、傳動(dong)(dong)離(li)(li)合、機(ji)(ji)身及(ji)腳踏開(kai)關等部分組成。驅動(dong)(dong)電(dian)(dian)(dian)機(ji)(ji)一般為0.5千(qian)瓦，采用(yong)單級或雙級三角帶傳速動(dong)(dong)力(li)，與電(dian)(dian)(dian)機(ji)(ji)只有(you)一種(zhong)速比。工作(zuo)(zuo)時(shi)(shi)電(dian)(dian)(dian)機(ji)(ji)運轉(zhuan)，但是不(bu)(bu)踩下腳踏開(kai)關時(shi)(shi)，傳送離(li)(li)合不(bu)(bu)動(dong)(dong)作(zuo)(zuo)，釘(ding)(ding)頭(tou)(tou)(tou)不(bu)(bu)釘(ding)(ding)釘(ding)(ding)，需要(yao)釘(ding)(ding)箱，人工架住紙板，踏下開(kai)關離(li)(li)合接通(tong)釘(ding)(ding)頭(tou)(tou)(tou)動(dong)(dong)作(zuo)(zuo)，循環釘(ding)(ding)釘(ding)(ding)。此種(zhong)機(ji)(ji)器(qi)比較(jiao)復雜(za)的(de)地方是釘(ding)(ding)頭(tou)(tou)(tou)以及(ji)機(ji)(ji)械離(li)(li)合。機(ji)(ji)頭(tou)(tou)(tou)內最重要(yao)部件是沖(chong)(chong)頭(tou)(tou)(tou)，隨著沖(chong)(chong)頭(tou)(tou)(tou)上下往復運動(dong)(dong)，在很短(duan)時(shi)(shi)間內(半秒左右)完成進(jin)線(xian)(含剪斷)壓(ya)形(xing)、沖(chong)(chong)釘(ding)(ding)、懸空4過程(cheng)一個工作(zuo)(zuo)循環，因結(jie)構設(she)計行進(jin)速度(du)(du)、加(jia)速度(du)(du)和停留時(shi)(shi)間不(bu)(bu)同，所需時(shi)(shi)間及(ji)易損零件也不(bu)(bu)相同，這樣(yang)就為制造(zao)商帶來一定難(nan)度(du)(du)。現用(yong)沖(chong)(chong)頭(tou)(tou)(tou)往復機(ji)(ji)構有(you)凸輪(lun)、偏心輪(lun)和偏心軸3種(zhong)形(xing)式(shi)。
