如今,有各種金屬制品如焊條、焊網(wǎng)、熱處理廚房用筐、汽車火花塞和排氣閥等,制造上述產(chǎn)品,鋼絲作為主要元素,是從線圈的形式理順,然后直絲按規(guī)定的長度被切成絲桿。對于這些順序操作,使用鋼絲矯直切割機?,F(xiàn)在,常規(guī)型線切割機正在被用在切斷鋼絲的刀頭,其長度和進給速度是有限的。本文調(diào)查了這種機器的矯直和切割過程。盡管這篇評論不能說詳盡無遺,但它可以被認為是對有興趣開發(fā)下一代鋼筋切割機的研究人員一個有價值的指導。
關鍵詞:鋼絲矯直切斷機(WSCM)、矯直、切斷
1.引言
Wire Straightening and Cutting Machines (WSCM) are widely used to extend wires from a roll or coil in
鋼絲調(diào)直切斷機(WSCM)廣泛用于矯直和切斷盤卷鋼筋。這些機器在不同的應用需求中具有廣泛的功能。一些機器配置為矯直和切斷各種冷拉拔絲絲and other nonferrous metal wires. They may cut the wire as per requirements in the required dimension and和其他有色金屬線。它們可以按規(guī)定的尺寸和要求切斷電線且可以連續(xù)工作。作。These machines are complied with three different processes such as feeding, straightening and cutting這臺機器有三種不同的工藝,如進料、矯直、切斷。這些機器有各種不同的功能,如不同矯直直徑,不同切斷長度,標準多功率電機矯直和切斷鋼絲。圖1和圖2顯示了WSCM可切斷直徑4毫米以下的鋼絲,和其工作layout respectively [1].布局[ 1 ]。

2.WSCM的單元
如WSCM布局顯示,它有基本部分(1)放線裝置,(2)進料裝置、(3)矯直裝置和(4)切斷裝置。
在放線裝置中,鋼絲可以從一個滑塊中通過,或更通常method employing a reel. Reel may be vertical or horizontal spindle. The vertical spindle should be used采用卷線法。卷筒可為立式或臥式主軸。立式主軸應該用于for wires up to approximately 2 mm to 4 mm in round.約為2毫米至4毫米的圓形鋼絲。
線。In feeding unit, feeding of the wire is usually done by grooved feeding rolls or “pinch rolls”. This在進料裝置中,通常用送料輥或“夾輥”進行送絲。這mechanism is power driven and pinches or squeezes the material so that the wire is either pulled and/or機制是電力驅(qū)動或者擠壓材料,電線是被拉或pushed through the machine. The feeding pressure to the rolls can be applied by hand through cams or推通過機器。給送料輥的進料壓力可以通過手動凸輪或spring. Figure 3 shows feed roller and its arrangement in the machine.彈簧。 圖3顯示了在機器中的進給輥和它的排列方式。
圖3 輥式矯直 圖4 旋轉(zhuǎn)軸矯直
矯直是對材料在制造過程中由于受力和扭矩的影響而引起的表觀瑕疵和應力進行消除straightened during its manufacture due to force and torque related influences. This applies to wire。它適用于鋼絲straightening, tube straightening, cable straightening, strip and profile shape straightening. Figure 3 and 4矯直,管矯直,電纜矯直,帶材和型材矯直。圖3和4顯示了輥式矯直機和圓桿矯直機的工作原理。show principle of roller straightening and rotary arbor straightening of wire.The roll straightened, consists of a series of rolls that are offset and which bend the wire beyond the
輥矯直, elastic limit a number of time in two or more planes as the wire runs through. The rolls are adjustable and當鋼絲穿過2個或多個平面時,由一系列的輥,抵消彎曲鋼絲中所超越彈性限位。輥可調(diào)整,the straightness obtained depends upon the skill of the operator making the adjustment. This method is獲得的鋼絲直線度取決于操作者做出調(diào)整的技能。這種方法是generally restricted to shaped wires such as hexagons, squares and flats except for minor straightening of一般限于成型線材如六角形、正方形和平板形外輕微的矯直round wire for removing coil bow before further forming.在進一步成形前去除線圈弓的圓形鋼絲。
The rotary straightened arbor rotates around the sock and imparts bending stresses in an overlapping
旋轉(zhuǎn)矯直心軸回繞使重疊的彎曲應力消失,獲得helical pattern that achieves a high degree of straightness inbound stock. The principle is that of a beam高程度的直線入站。原理是一束affect the moves around and along the wire at the same time producing a helix or wave disappears when the當在同一時間產(chǎn)生螺旋線或波消失時,影響周圍的移動和沿導線的部分重疊的直絲生產(chǎn)。直線度受各種因素控制,但mainly feeds, speeds and the condition of the straightening dies.主要是進料,速度和矯直模具的條件。
The straightness and surface condition of the wire is depended on the straightened dies because the
鋼絲的平直度和表面狀況取決于其矯直模具,因為其rotary arbor is friction device with the die material is compatible with the wire and the contour presents旋轉(zhuǎn)桿是與模具材料的摩擦裝置與導線和輪廓線兼容enough area to support the load of bending. The center distance between the straightened dies must be有足夠的面積來支撐彎曲載荷。矯直模具之間的中心距必須是within specific limits for a particular wire diameter to give the correct beam effect and bending stress to在特定的鋼絲直徑范圍內(nèi)給予正確的光束效應和彎曲應力produce a straight product.生產(chǎn)一條直的產(chǎn)品。
“切斷”或剪切過程是在矯直過程之后。一般有2個classifications of cut off mechanisms; one being the stationary shear where in the wire is actually stopped切斷機構的分類;一類是固定的剪切,在切割周期中鋼絲實際上是停止的止during the cutting cycle, and the other the “travel-cut” or flying shear in which the shearing mechanism,另一類是 “行程剪切”或飛剪,剪moves along with the wire during the cutting cycle. The flying shear cut off is superior to the stationary在切割周期中隨金屬絲一起移動。對于許多應用軟絲或小直徑鋼絲,飛剪剪斷優(yōu)越于固定shear type; for many applications using soft wire or small diameters. However, the stationary shear will剪切型。然而,固定剪切也會give satisfactory results. When running hard wire or alloy through a high speed rotary arbor, flying shear is給出一個令人滿意的剪切結果。在高速旋轉(zhuǎn)桿上運行時,通過高速旋轉(zhuǎn)軸或合金,飛剪necessary, since if the wire were stopped for cutoff in the arbor, it may become overworked and overheated必要的,因為如果鋼絲在軸上靜止切斷,它可能會過熱而導致破壞心軸。致 。
In such type of machine, the energy of cutting is usually supplied by a flywheel and is transmitted either
對于這種類型的機器,切割的能量通常由一個飛輪提供,并directly or through clutch or brakes. Here in projected machine, power of motor is transmitted to flywheel直接發(fā)送或通過離合器或制動器傳遞。在設計的機器中,電機的功率by belt and pulley. Figure 5 and figure 6 shows flying shear in WSCM. Major parts of cutting unit in the由飛輪傳遞給皮帶和皮帶輪。圖5和圖6顯示了WSCM中的飛剪機構。切割裝置的主要部件machine are fly wheel, guide bar/scaling unit, stands, cutting block and cam mechanism.有飛輪,導向桿/定標單元,底座,切割塊和凸輪機構。

3.WSCM的工作過程Wire coil is mounted on the paying off unit. At time of start, wire is fed between the spring operated rollers
鋼絲盤被安裝在放線單元。開始時,在彈簧操作輥之間送線到of feeding unit, they pull the wire from paying off unit and push in to rotating spinner. The rotating spinner進給單元,它們把鋼絲從放線單元推到旋轉(zhuǎn)器。旋轉(zhuǎn)器矯直鋼絲后由送料滾筒裝置straightens the wire and again the roller of feeding unit pull the wire from spinner and push it in to cutter矯直鋼絲后由由 把鋼絲從旋轉(zhuǎn)輥推到切割機,nozzle and then Guide bar where an adjustable spring loaded stopper which can be adjusted -depending on然后通過導向桿,一種可根據(jù)the rod length required, blocks movement of wire. The blocking of movement of wire results in an increase所需鋼絲的桿長而調(diào)整彈簧負載的止動器。增加彈簧壓力從而增加鋼絲運動的阻塞,和由此產(chǎn)生的壓力驅(qū)動切割機刀頭往復運動形成一個完整的切割行程。一種錐形支撐裝置,在切割端輔助對準the scaling unit incorporating the stopper mechanism in line with machine axis[1].縮放單元軸線的止動機構[ 1 ]。
