作者:admin 發布日期:2016/6/27 17:25:17

滾絲(si)機操作規程

1、試車前的準(zhun)備

首先(xian)打開(kai)電氣箱,檢(jian)查(cha)各個接(jie)線端(duan)子是(shi)否有(you)松動(dong)現象(xiang),空氣開(kai)關是(shi)否合(he)好,手柄位置應(ying)(ying)該向上(shang),需要注意的是(shi),還應(ying)(ying)檢(jian)查(cha)各個部分電線是(shi)否完好,不(bu)應(ying)(ying)有(you)破皮現象(xiang),如(ru)發(fa)現請及時更換。最后要檢(jian)查(cha)漏電保護器是(shi)否靈敏(min)。

2、開機

合上(shang)電源開(kai)(kai)關,面板上(shang)的指(zhi)示燈亮,打開(kai)(kai)油泵電機(ji),將(jiang)模(mo)式選擇開(kai)(kai)關扳(ban)在手動位置,按綠色按鈕進(jin),滑(hua)動座應該前(qian)進(jin),若沒有(you)動作,檢查液壓電機(ji)是否反轉。

3、模(mo)式選(xuan)擇(ze)開關

1)轉換開(kai)關(guan)(guan)若扳(ban)(ban)在右側位(wei)置,則是自(zi)動(dong)(dong),由時(shi)間(jian)繼電(dian)器調整進退(tui)速度,調整時(shi)間(jian)時(shi)應將開(kai)關(guan)(guan)扳(ban)(ban)在中間(jian)手動(dong)(dong)位(wei)置,調整好時(shi)間(jian)后(hou)再扳(ban)(ban)回自(zi)動(dong)(dong)。此時(shi)當踏下(xia)腳踏開(kai)關(guan)(guan)時(shi)滑(hua)動(dong)(dong)座(zuo)后(hou)退(tui),(用于處理非正常情況(kuang),如工件沒(mei)放好等)。也(ye)可按急(ji)退(tui)按鈕(niu)使滑(hua)動(dong)(dong)座(zuo)后(hou)退(tui)。

2)轉換開(kai)關若(ruo)扳在中間手動(dong)(dong)(dong)(dong)位置(zhi),按(an)下綠色前(qian)進(jin)(jin)按(an)鈕,滑(hua)動(dong)(dong)(dong)(dong)座(zuo)前(qian)進(jin)(jin),松(song)開(kai)按(an)鈕,滑(hua)動(dong)(dong)(dong)(dong)座(zuo)停(ting)止(zhi)動(dong)(dong)(dong)(dong)作(zuo),此時滑(hua)動(dong)(dong)(dong)(dong)座(zuo)也(ye)不前(qian)進(jin)(jin)退。按(an)下紅色后退按(an)鈕,滑(hua)動(dong)(dong)(dong)(dong)座(zuo)后退,松(song)開(kai)按(an)鈕,滑(hua)動(dong)(dong)(dong)(dong)座(zuo)停(ting)止(zhi)動(dong)(dong)(dong)(dong)作(zuo),此時滑(hua)動(dong)(dong)(dong)(dong)座(zuo)也(ye)不后退。 滑(hua)動(dong)(dong)(dong)(dong)座(zuo)停(ting)止(zhi)動(dong)(dong)(dong)(dong)作(zuo)。這兩(liang)個(ge)按(an)鈕屬于電動(dong)(dong)(dong)(dong)按(an)鈕,用于調整滾絲輪(lun)。在自(zi)動(dong)(dong)(dong)(dong)模式下,這兩(liang)個(ge)按(an)鈕同樣起著點(dian)動(dong)(dong)(dong)(dong)的作(zuo)用。

3)轉換開關(guan)若(ruo)扳在左側位置(zhi),則是手(shou)動(dong)模式,此(ci)時踏(ta)(ta)下(xia)腳踏(ta)(ta)開關(guan),滑動(dong)座前進(jin),松(song)開后退,與(yu)全自動(dong)時腳踏(ta)(ta)開關(guan)的作用正(zheng)好相反。在手(shou)動(dong)模式下(xia),按下(xia)綠(lv)色(se)前進(jin)按鈕前進(jin),而松(song)開時則自動(dong)退回。

4、調(diao)整后退行程

后退(tui)行(xing)(xing)程的調(diao)(diao)(diao)整是機床右側(ce)的旋(xuan)鈕,后退(tui)行(xing)(xing)程過(guo)長效率(lv)低,過(guo)短會出(chu)現(xian)拿不出(chu)來的現(xian)象(xiang),應(ying)該根據實際(ji)情況調(diao)(diao)(diao)整,同時要配合時間繼電(dian)器進行(xing)(xing)調(diao)(diao)(diao)整。

5、通絲(si)角度調整

1)左輪(lun)向(xiang)上(shang),右輪(lun)向(xiang)下,正負角度一致。

2)角(jiao)度(du)不(bu)正確還(huan)需把左(zuo)輪(lun)和右(you)輪(lun)向大的方向調整(zheng)或小(xiao)的方向調整(zheng),即兩個接觸點(dian)錯誤必須一致。

3)調整亂扣時,T型(xing)盤(pan)向下旋轉(zhuan),或(huo)向上旋轉(zhuan)

4)如果(guo)定(ding)絲輪(lun)兩根(gen)主(zhu)軸都(dou)在0°上時,無需調試角(jiao)度,調整亂扣即可。

6、機(ji)床的調整(zheng)與操作(zuo)

1)、改變選(xuan)(xuan)擇(ze)開(kai)關工作位置(zhi),可選(xuan)(xuan)擇(ze)自動(dong)滾壓和(he)腳踏模式(shi)滾壓以及手動(dong)模式(shi)。

A、自(zi)動(dong)循(xun)環模式:啟(qi)動(dong)液壓(ya)電(dian)機,將選擇開關扳至自(zi)動(dong),根據滾壓(ya)需要分別調整自(zi)動(dong)進滾壓(ya)時(shi)(shi)(shi)間和后(hou)退停歇時(shi)(shi)(shi)間,這時(shi)(shi)(shi),滑動(dong)座在前(qian)進時(shi)(shi)(shi)間繼電(dian)器(qi)控制的液壓(ya)力作(zuo)用下(xia)做進給運動(dong),滑動(dong)座在停歇時(shi)(shi)(shi)間繼電(dian)器(qi)控制下(xia),做后(hou)退停歇運動(dong)。  

B、腳(jiao)(jiao)踏(ta)式循環模式:將(jiang)選擇開關扳至腳(jiao)(jiao)踏(ta)位置,這時(shi)(shi)時(shi)(shi)間繼(ji)電器(qi)停止(zhi)工(gong)作,踏(ta)下腳(jiao)(jiao)踏(ta)開關,滑動(dong)座在(zai)液壓(ya)壓(ya)力(li)作用下做前進(jin)運(yun)動(dong),在(zai)完(wan)成(cheng)工(gong)作滾(gun)壓(ya)后抬(tai)腳(jiao)(jiao),滑動(dong)座在(zai)液壓(ya)壓(ya)力(li)作用下退(tui)回。再踏(ta)下腳(jiao)(jiao)踏(ta)開關工(gong)作,動(dong)作依次重復。

2)選擇滾輪:滾輪選用時,能用窄的(de)不(bu)用寬(kuan)的(de),寬(kuan)度應大于(yu)被加工螺紋的(de)長(chang)度。

3)工件(jian)支(zhi)承座和(he)支(zhi)承塊(kuai)的調整:工件(jian)支(zhi)承座和(he)支(zhi)承塊(kuai)是用來支(zhi)承工件(jian)在滾絲(si)輪間的正確位置(zhi)進(jin)行滾壓。

滾絲機

A、支(zhi)承座導軌面上的(de)徑向位置(zhi)調整,機床支(zhi)承座應在工(gong)(gong)件中心(xin)位置(zhi),隨(sui)滾壓工(gong)(gong)件直徑的(de)變(bian)化,支(zhi)承座位置(zhi)也需(xu)要(yao)變(bian)化,調整方法:松(song)開兩個固定螺栓,將支(zhi)承座移到(dao)所(suo)需(xu)要(yao)的(de)位置(zhi),緊(jin)固螺栓即可。

B、支(zhi)承(cheng)(cheng)塊的調整:支(zhi)承(cheng)(cheng)塊裝(zhuang)在支(zhi)承(cheng)(cheng)座上面,頂端(duan)焊有硬(ying)質合金,松開支(zhi)承(cheng)(cheng)塊緊固(gu)螺(luo)絲,在支(zhi)承(cheng)(cheng)塊底部增減墊(dian)片來調整支(zhi)承(cheng)(cheng)塊高低,然后緊固(gu)螺(luo)絲,支(zhi)承(cheng)(cheng)塊高低在滾壓過(guo)程中起(qi)重(zhong)要作用。

C、支承塊高(gao)度的選擇(ze):高(gao)度取決(jue)于(yu)滾(gun)壓工(gong)(gong)(gong)件(jian)(jian)的規(gui)格,同時(shi)根據不同工(gong)(gong)(gong)件(jian)(jian)材質(zhi),可(ke)以略(lve)微(wei)偏高(gao)或偏低(di)。由此可(ke)分為(wei)(wei)兩(liang)種(zhong)情況(kuang):一種(zhong)是工(gong)(gong)(gong)件(jian)(jian)中(zhong)(zhong)(zhong)(zhong)(zhong)心(xin)(xin)稍低(di)于(yu)滾(gun)絲(si)輪中(zhong)(zhong)(zhong)(zhong)(zhong)心(xin)(xin),這種(zhong)方式使(shi)(shi)滾(gun)壓過程(cheng)(cheng)中(zhong)(zhong)(zhong)(zhong)(zhong)穩定性強,但(dan)(dan)支承塊頂(ding)端容易磨損 螺(luo)(luo)紋(wen),螺(luo)(luo)紋(wen)頂(ding)端容易刮(gua)掉。另(ling)一種(zhong)是工(gong)(gong)(gong)件(jian)(jian)中(zhong)(zhong)(zhong)(zhong)(zhong)心(xin)(xin)稍高(gao)于(yu)滾(gun)絲(si)輪中(zhong)(zhong)(zhong)(zhong)(zhong)心(xin)(xin),可(ke)以減輕支承塊頂(ding)端磨損,滾(gun)壓螺(luo)(luo)紋(wen)頂(ding)端不被刮(gua)傷,但(dan)(dan)在滾(gun)壓過程(cheng)(cheng)中(zhong)(zhong)(zhong)(zhong)(zhong),工(gong)(gong)(gong)件(jian)(jian)容易上跳而脫離(li)滾(gun)壓,在一般情況(kuang)下對(dui)普通(tong)鋼、優質(zhi)碳(tan)素鋼和有色金屬工(gong)(gong)(gong)件(jian)(jian),可(ke)使(shi)(shi)工(gong)(gong)(gong)件(jian)(jian)中(zhong)(zhong)(zhong)(zhong)(zhong)心(xin)(xin)略(lve)高(gao)于(yu)滾(gun)絲(si)輪中(zhong)(zhong)(zhong)(zhong)(zhong)心(xin)(xin),使(shi)(shi)用中(zhong)(zhong)(zhong)(zhong)(zhong)應(ying)根據實際(ji)情況(kuang),以工(gong)(gong)(gong)件(jian)(jian)不跳不刮(gua)絲(si)為(wei)(wei)目(mu)標。

4)、支(zhi)承塊(kuai)寬(kuan)度(du)的(de)(de)選擇: 支(zhi)承塊(kuai)寬(kuan)度(du)應以滾(gun)壓時,滾(gun)絲輪不會與支(zhi)承塊(kuai)相碰為(wei)出發(fa)點,對(dui)M10以下規格(ge)的(de)(de)工(gong)件,應取接近于允許的(de)(de)最(zui)大寬(kuan)度(du),對(dui)于M10以上的(de)(de)工(gong)件,允許支(zhi)承塊(kuai)頂端(duan)寬(kuan)度(du)較大,但也沒有必要(yao)超過18mm。

5)、滾絲輪牙(ya)位調整:(常(chang)見牙(ya)位調整有(you)兩(liang)種方法)

A、樣件對(dui)牙(ya)位法:樣件對(dui)牙(ya)位法就(jiu)是借(jie)助(zhu)螺(luo)絲(si)樣件調(diao)整兩滾(gun)輪(lun)(lun)的牙(ya)位位置,通過(guo)調(diao)整動力分配(pei)箱上的滾(gun)輪(lun)(lun)牙(ya)位調(diao)整整盤(pan),使一(yi)個(ge)滾(gun)絲(si)輪(lun)(lun)單獨旋轉,另一(yi)個(ge)滾(gun)絲(si)輪(lun)(lun)不動,來錯(cuo)過(guo)一(yi)個(ge)牙(ya)位,使兩滾(gun)絲(si)輪(lun)(lun)牙(ya)位與(yu)樣件螺(luo)紋相(xiang)符即可(ke)。

B、工(gong)作壓(ya)痕法:啟動主(zhu)電機使滾絲(si)機轉動,啟動液壓(ya)電機把工(gong)件(jian)放到支承塊上(shang),踏(ta)下(xia)腳(jiao)踏(ta)開關(guan),使一(yi)個滾絲(si)輪(lun)前移,兩滾絲(si)輪(lun)擠住工(gong)件(jian)羅(luo)(luo)坯,并隨滾絲(si)輪(lun)一(yi)起(qi)轉動,使滾絲(si)輪(lun)牙頂(ding)在羅(luo)(luo)坯上(shang)壓(ya)出印(yin)(yin)痕立即抬(tai)起(qi)腳(jiao)踏(ta)開關(guan),取出壓(ya)有印(yin)(yin)痕的(de)羅(luo)(luo)坯,根據羅(luo)(luo)坯上(shang)的(de)連(lian)接印(yin)(yin)痕,調(diao)(diao)整滾絲(si)輪(lun)牙位(wei)調(diao)(diao)整盤,使印(yin)(yin)痕連(lian)接成一(yi)條連(lian)續螺旋線即可。

(注:樣件(jian)對牙(ya)法(fa)(fa)(fa)和工(gong)件(jian)壓痕法(fa)(fa)(fa)相比(bi)(bi)(bi)較,壓痕法(fa)(fa)(fa)比(bi)(bi)(bi)樣件(jian)對牙(ya)法(fa)(fa)(fa)精確度高,使(shi)用于(yu)多種規(gui)格螺紋,缺(que)點(dian)是比(bi)(bi)(bi)較麻煩,必(bi)須(xu)有幾(ji)件(jian)至十幾(ji)件(jian)羅坯(pi),才可(ke)(ke)以(yi)調(diao)整完畢,樣件(jian)對牙(ya)法(fa)(fa)(fa)只(zhi)需要有一(yi)個(ge)螺紋樣件(jian)即可(ke)(ke),但精度低,更不適于(yu)小螺距細工(gong)件(jian)的牙(ya)位(wei)調(diao)整。

6)機床液壓(ya)行程(cheng)(cheng)的(de)調整:液壓(ya)行程(cheng)(cheng)包括:滾壓(ya)行程(cheng)(cheng)、后(hou)退(tui)行程(cheng)(cheng)

A、滾(gun)壓(ya)(ya)行程(cheng)(cheng)相當于螺紋的牙形高度,其調整(zheng)步驟(zou)是:a、啟(qi)動(dong)(dong)液壓(ya)(ya)電機(ji),踏下腳踏開關(guan),使(shi)滑動(dong)(dong)座(zuo)前(qian)滾(gun)絲輪(lun)(lun)進(jin)給到位,查看兩個滾(gun)輪(lun)(lun)之(zhi)間距離(li),中心距不應低(di)于加工(gong)工(gong)件(jian)螺紋根(gen)徑,如果距離(li)過(guo)大,則(ze)工(gong)件(jian)螺紋深(shen)度不夠,過(guo)小(xiao)則(ze)機(ji)床滾(gun)壓(ya)(ya)吃(chi)力。b、如需調整(zheng),可(ke)搖(yao)動(dong)(dong)滑動(dong)(dong)座(zuo)上的行程(cheng)(cheng)手輪(lun)(lun),順時(shi)針(zhen)方向旋轉則(ze)向前(qian)移動(dong)(dong),逆時(shi)針(zhen)方向旋轉則(ze)向后移動(dong)(dong)。(注(zhu):滑動(dong)(dong)座(zuo)進(jin)給速(su)度直接調整(zheng)節流閥旋轉手柄,以機(ji)床上所標方向調整(zheng)快(kuai)慢,過(guo)快(kuai)容(rong)易使(shi)工(gong)件(jian)卡(ka)住,過(guo)慢生產工(gong)作(zuo)效率過(guo)低(di),小(xiao)螺距可(ke)以調快(kuai),大螺距則(ze)不可(ke)過(guo)快(kuai)。

7)壓(ya)力(li)(li)大小的調整:直接旋轉溢流(liu)閥手柄即可,壓(ya)力(li)(li)大時(shi)滾(gun)壓(ya)時(shi)間短,壓(ya)力(li)(li)小時(shi)滾(gun)壓(ya)時(shi)間長,壓(ya)力(li)(li)過大容易損壞滾(gun)絲輪,壓(ya)力(li)(li)大小應根(gen)據(ju)螺紋精(jing)度調整。(注(zhu):開始(shi)工作(zuo)前應反復踩腳(jiao)踏開關,進行油缸排氣。

8)時間(jian)繼(ji)電(dian)器滾(gun)(gun)壓(ya)(ya)時間(jian)和(he)后退時間(jian)的(de)(de)調(diao)(diao)(diao)整(zheng):液(ye)壓(ya)(ya)時間(jian)長短確定,是(shi)根據(ju)工件的(de)(de)機械性(xing)能(neng)、螺(luo)紋(wen)(wen)規格、螺(luo)紋(wen)(wen)精(jing)(jing)度(du)來(lai)調(diao)(diao)(diao)整(zheng)的(de)(de),對于硬度(du)較(jiao)高,精(jing)(jing)度(du)要求(qiu)高的(de)(de)螺(luo)紋(wen)(wen),應(ying)選用較(jiao)長的(de)(de)液(ye)壓(ya)(ya)時間(jian),否(fou)則被(bei)滾(gun)(gun)壓(ya)(ya)的(de)(de)螺(luo)紋(wen)(wen)工件中(zhong)徑(jing)、外徑(jing)、內徑(jing)產生(sheng)橢圓,應(ying)根據(ju)實(shi)際(ji)情況調(diao)(diao)(diao)整(zheng)液(ye)壓(ya)(ya)時間(jian)。后退時間(jian)的(de)(de)調(diao)(diao)(diao)整(zheng)是(shi)根據(ju)工人(ren)操作熟練(lian)程度(du)進行調(diao)(diao)(diao)整(zheng),調(diao)(diao)(diao)整(zheng)時間(jian)繼(ji)電(dian)器上的(de)(de)數字按鈕(niu),即可得(de)到所(suo)要求(qiu)的(de)(de)前進時間(jian)和(he)后退時間(jian)。

9)機(ji)床(chuang)滾絲長度(du):滾絲長度(du)可根據(ju)需要而(er)定(ding),一(yi)般情況下m6-m10可加(jia)工(gong)3m長,m12-m16可加(jia)工(gong)2m長,m16-m20可加(jia)工(gong)1m長

11、滾(gun)絲輪(lun)(lun)(lun)轉(zhuan)數的調(diao)整:機床(chuang)有兩對交換齒(chi)輪(lun)(lun)(lun),變換滾(gun)絲輪(lun)(lun)(lun)轉(zhuan)速,調(diao)整轉(zhuan)速時,打(da)開傳動箱(xiang)外的交換齒(chi)輪(lun)(lun)(lun)箱(xiang),安(an)裝齒(chi)輪(lun)(lun)(lun),選(xuan)擇(ze)所需滾(gun)輪(lun)(lun)(lun)轉(zhuan)數(見(jian)交換齒(chi)輪(lun)(lun)(lun)表)。

12、機(ji)床(chuang)主軸(zhou)(zhou)(zhou)傾(qing)(qing)斜(xie)角(jiao)的(de)(de)調(diao)(diao)整:主軸(zhou)(zhou)(zhou)角(jiao)的(de)(de)調(diao)(diao)整是以(yi)工件螺(luo)紋,螺(luo)旋角(jiao)和軸(zhou)(zhou)(zhou)角(jiao)調(diao)(diao)整表相對應的(de)(de)值制作調(diao)(diao)整棒(bang)(bang)或調(diao)(diao)整塊來調(diao)(diao)整主軸(zhou)(zhou)(zhou)的(de)(de)傾(qing)(qing)斜(xie)角(jiao)度。調(diao)(diao)整時先松開輪臺傾(qing)(qing)斜(xie)角(jiao)固(gu)定(ding)絲,將所需(xu)調(diao)(diao)整棒(bang)(bang)或調(diao)(diao)整塊塞(sai)在0°為14的(de)(de)空隙內(nei),按(an)所需(xu)方向(xiang),向(xiang)上調(diao)(diao)或向(xiang)下調(diao)(diao),并與棒(bang)(bang)或塊靠緊,最后(hou)將螺(luo)釘旋緊,取下調(diao)(diao)整棒(bang)(bang)或塊。
