由凸(tu)輪傳動(dong)連桿，使(shi)節距(ju)刀機器里面推(tui)出，更好(hao)的(de)(de)估大節距(ju)的(de)(de)彈(dan)簧(huang)。五、切斷(duan)(duan)機構：切斷(duan)(duan)機構是(shi)卷(juan)繞成形(xing)(xing)(xing)(xing)(xing)后，切斷(duan)(duan)鋼(gang)絲是(shi)彈(dan)簧(huang)落下的(de)(de)一個加工(gong)動(dong)作(zuo)，切斷(duan)(duan)時通過刀和(he)芯來(lai)完成。中凹形(xing)(xing)(xing)(xing)(xing)螺旋彈(dan)簧(huang)的(de)(de)性能與(yu)圓(yuan)(yuan)錐(zhui)螺旋彈(dan)簧(huang)相似，多用(yong)于坐墊(dian)和(he)床墊(dian)等。彈(dan)簧(huang)鋼(gang)絲的(de)(de)載面有(you)圓(yuan)(yuan)形(xing)(xing)(xing)(xing)(xing)和(he)矩形(xing)(xing)(xing)(xing)(xing)等，以圓(yuan)(yuan)形(xing)(xing)(xing)(xing)(xing)截面為(wei)常(chang)用(yong)。按形(xing)(xing)(xing)(xing)(xing)狀分類(lei)可分為(wei)：圓(yuan)(yuan)柱彈(dan)簧(huang)、塔形(xing)(xing)(xing)(xing)(xing)彈(dan)簧(huang)、D形(xing)(xing)(xing)(xing)(xing)彈(dan)簧(huang)、U形(xing)(xing)(xing)(xing)(xing)彈(dan)簧(huang)異形(xing)(xing)(xing)(xing)(xing)彈(dan)簧(huang)、O形(xing)(xing)(xing)(xing)(xing)彈(dan)簧(huang)、W形(xing)(xing)(xing)(xing)(xing)彈(dan)簧(huang)、S形(xing)(xing)(xing)(xing)(xing)彈(dan)簧(huang)等。

送(song)料輪旋(xuan)轉(zhuan)(zhuan)一周，送(song)料長度就是送(song)料輪的(de)周長，彈簧(huang)的(de)展(zhan)開長度可由送(song)料輪的(de)旋(xuan)轉(zhuan)(zhuan)圈(quan)數(shu)決定，扇形不完全齒(chi)輪的(de)齒(chi)數(shu)是控(kong)制送(song)料輪的(de)旋(xuan)轉(zhuan)(zhuan)圈(quan)數(shu)。中凹(ao)形螺旋(xuan)彈簧(huang)的(de)性能與(yu)圓錐螺旋(xuan)彈簧(huang)相似，多用(yong)于坐墊和床墊等。彈簧(huang)鋼絲的(de)載面有圓形和矩形等，黃(huang)山彈簧(huang)廠家，以圓形截(jie)面為常用(yong)。生產變徑(jing)彈簧(huang)時，如中凸、截(jie)錐形彈簧(huang)、上(shang)頂(ding)杠(gang)前(qian)后兩個螺栓(shuan)松開，讓頂(ding)桿(gan)在刀架(jia)里來回(hui)伸縮(suo)，以改(gai)變彈簧(huang)外經(jing)，通過(guo)變徑(jing)凸輪驅動頂(ding)桿(gan)，達到生產各種變徑(jing)彈簧(huang)的(de)目的(de)。

除支(zhi)承圈(quan)(quan)(quan)以(yi)外(wai)，其余各圈(quan)(quan)(quan)均參加(jia)受力(li)變形(xing)，并保持相等(deng)的?節距，稱為有(you)效圈(quan)(quan)(quan)數(shu)(shu)，?有(you)效圈(quan)(quan)(quan)數(shu)(shu)n = 總圈(quan)(quan)(quan)數(shu)(shu)n1 - 支(zhi)承圈(quan)(quan)(quan)數(shu)(shu)nz；中(zhong)凹(ao)形(xing)螺(luo)(luo)旋(xuan)彈(dan)簧的性能與圓錐螺(luo)(luo)旋(xuan)彈(dan)簧相似(si)，多用于坐墊和床墊等(deng)。彈(dan)簧鋼絲的載面有(you)圓形(xing)和矩形(xing)等(deng)，以(yi)圓形(xing)截面為常用。圓柱螺(luo)(luo)旋(xuan)壓縮(suo)彈(dan)簧的?名稱代號為Y，彈(dan)簧在端圈(quan)(quan)(quan)形(xing)式上分為A型(兩端圈(quan)(quan)(quan)并緊磨平(ping)）和B型(兩端圈(quan)(quan)(quan)并緊鍛平(ping)）兩種。
