接到生產(chǎn)指令單或拿到一個樣品,首先先確定它的鋼絲直徑、圈數(shù)、彈簧外徑內(nèi)徑、螺距等參數(shù),然后選用相印的鋼絲放到料盤上,鋼絲逆時針穿過料盤上的每一個孔,先從料盤左前方的穿起。
然后穿過校直輪,再是壓線板,壓線板只能選用相同或略大于鋼絲直徑的,不能小。再繼續(xù)穿過送線輪,送線輪也必須選相同或略大于鋼絲直徑的,且要朝下放置。鋼絲越大送線輪要壓的越緊,以雙手緊為止。后是芯棒,芯棒也只能選用相同或略大于鋼絲直徑的,小于1.2包括1.2的要加套筒。
再仔細(xì)觀察樣品在頭腦中確定哪步先走,需要什么刀,打圈用卷曲刀打彎用折彎刀。然后是調(diào)整刀具了,首先要裝切刀,切刀一般是把角度搖到-120度然后用手拉下刀臂并使凸輪高點(diǎn)頂住,鎖緊凸輪,然后切刀與芯棒必須零靠零,如果沒靠緊會產(chǎn)生毛刺拖頭。之后按刀具的先后安好其他凸輪與刀具。具體什么樣品用什么刀多大的凸輪及凸輪位置可以參照視頻圖片。然后用手輪搖到要測試的那把刀,然后打彎或打圈試試,打出來的彎圈大了可以調(diào)節(jié)機(jī)械臂上的上下螺絲使它往下,或者調(diào)節(jié)刀架上的前后螺絲使刀往芯棒靠,總之是為了減小芯棒與刀之間的距離。圈彎小了往上或往前使刀與芯棒距離變大。刀臂左右的螺絲可以調(diào)節(jié)刀的左右,一般是使刀對準(zhǔn)芯棒中心可以,特殊情況要求密圈則可以往右偏一點(diǎn)點(diǎn),疏圈則往左一點(diǎn)點(diǎn),但是都不能偏離的使刀都不能打圈了。
刀具的角度都調(diào)節(jié)好了,可以進(jìn)行編程,編程是要先手搖樣品的段,設(shè)定好開始角與結(jié)束角,然后手搖出跟樣品直觀差不多的送線長度并確認(rèn),至于轉(zhuǎn)芯則只要芯棒不會與刀相撞并且要避免使芯棒的薄弱處對準(zhǔn)刀的運(yùn)動方向,否則會使芯棒爆掉。然后按步一樣的編程方式確定好開始角結(jié)束角轉(zhuǎn)芯及送線長度。一直到后一步切斷,后一步的開始角是切刀切斷鋼絲的位置,結(jié)束角一定要設(shè)為零,送線、轉(zhuǎn)芯也必須是零。后再引用結(jié)束指令E。
接下去是細(xì)調(diào),用手搖出一個彈簧與樣品對照哪一步不對改哪一步的送線長度,相差1—2個毫米的送線長度一般改100左右,比如角度沒到位、圈數(shù)不夠、直線長度不夠都要加送線,反之角度過了、圈數(shù)多了、直線長度長了都要減送線。細(xì)調(diào)完了按下單條看彈簧出來的速度是否合理,如果是單步太快在這步的后面的速比填上小于1的數(shù)值,太慢則填大于1的數(shù)值。如果是整體太慢則改程序步的S指令后面的開始角下的30,送線下的20,轉(zhuǎn)芯下的20,數(shù)值越大則速度越快,每次加減不能超過5,要逐次加減。全部調(diào)好可以按下自動運(yùn)行開始。

Receiving the production orders or to get a sample, first determine the diameter of steel wire, coil number, the outer diameter of the spring diameter, pitch and other parameters, and then choose printed wire into the tray, wire anti-clockwise across the tray on every hole, first from the tray in front left.
Then through the straightening wheels, then pressing line plate, pressure plate can only choose the same or slightly larger than the diameter of steel wire, not a small. Continue through the wire feeding wheel, a wire feeding wheel must also choose the same or slightly larger than the diameter of the wire, and be placed face down. The wire is wire feeding wheel to press more tight, with both hands tightly. Finally the mandrel mandrel, also can use the same or slightly larger than the diameter of the wire, less than 1.2including 1.2with sleeve.
Carefully observed samples in mind to determine which step ahead, need what cutter, circle curl bending bending knife with knife. And then the adjustment tool, first installed cutter, cutter is usually angle wave to -120 degrees and then hand pull arm and the cam peak withstand, locking cam, and the cutter and the mandrel must be zero by zero, if not close will produce the burr drag head. After the tool has other cam and tool. What specific samples using knives much of the cam and the cam position can refer to video pictures. Then using the handwheel wave to test the knife, and then bending or hit a circle to try, out of the circle big can modulate the mechanical arm on the upper and the lower screw it down, or adjusting the cutter frame before and after the screw mandrel cutter to rely on, it is in order to reduce the distance between the mandrel and the sword. Circle bend small went on to make a knife and a mandrel or forward distance is enlarged. Cutter arm around the screw can adjust the cutter, is generally make the knife aligned mandrel center can, special circumstances require sealing rings can right a little bit, a ring is a little to the left, but can't deviate from the knife can play circle.
Tool angle is adjusted, it can be programmed, programming is to first hand samples from the first section, set the start angle and end angle, and then hand out with the sample directly about wire feed length and confirmation, as to the core so that the mandrel will and knife collision and avoid the weak points of the mandrel on the direction of movement of the knife, or make the mandrel burst. Then the first step as programmatically determine good start angle end angle rotating core and wire feed length. Until the last step cut off, the final step of the starting angle is a cutting knife to cut off the wire end position, angle must be set to zero, the wire, turn the core must be zero. Finally, reference end directive E.
Then there are fine, hand out a spring and sample control which step wrong change which step of the wire feed length, a difference of 1-2mm wire feed length to about 100, for example, did not reach the designated position, angle, circle number not straight length enough to add the wire, and angle the number of laps, the line length, to reduce the wire. Fine finished press single watch spring up to speed is reasonable, if one step too soon in this step back fill ratio values less than 1, it was too slow, fill a value larger than 1. If the overall too slowly changed procedures first step S instruction behind the starting angle under 30, the wire under 20, a rotating core under the 20numerical value is greater, faster, each addition and subtraction can not exceed 5, to successive addition and subtraction. All the good can be pressed automatically start.
