本文簡要分析了鋼筋調直切斷機、彎曲機、套絲機的工作原理及其的應用。鋼筋作為混凝土的骨架構成鋼筋混凝土，成為建筑結構中使用面大、量大的主材。在澆注混凝土前，鋼筋必須制成一定規(guī)格和形式的骨架納入模板中。制作鋼筋骨架，需要對鋼筋進行強化、拉伸、調直、切斷、彎曲、連接等加工，最后才能捆扎成形。由于鋼筋用量極大，加工操作難以完成，需要采用各種專用機械進行加工，這類機械稱為鋼筋加工機械，簡稱鋼筋機械。為了增加鋼筋混凝土粱、屋架等主要結構的強度．常采用預應力鋼筋混凝土，即預先將鋼筋(鋼絲束或鋼鉸線)拉伸到設計應力，并錨固于結構受拉區(qū)內，使其產生有利的壓應力利應變，用以抵消荷載時產生的拉應力，從而增加其荷載能力。張拉鋼筋產生預應力的專用設備，稱為鋼筋預應力機械。現(xiàn)代建筑施工中，由于鋼筋混凝土用量日益增大，鋼筋加工量相應增加，促使鋼筋機械不斷發(fā)展。一般施工現(xiàn)場和預制混凝土構件廠都有一定規(guī)模的鋼筋加工車間，為實現(xiàn)鋼筋加工機械化提供有利條件。隨著社會經濟的發(fā)展,產品的多樣化及對市場的快速反應成為企業(yè)能否在激烈的市場競爭中處于有利位置的必備能力，這就對企業(yè)的生產設備提出了更高地要求如何提高生產設備的柔性和效率,滿足產品的多樣化的需要,是每個企業(yè)都面臨著的一個重要問題，尤其是近些年來住宅產業(yè)、能源交通等基礎設施建設不斷發(fā)展，鋼筋砼結構的跨度和規(guī)模不斷擴大，對建筑物、構筑物使用年限的提高，對抗震、節(jié)能、節(jié)材要求的提高，施工難度不斷增加，傳統(tǒng)施工方法及現(xiàn)場手工操作已不適應工程的要求，只有發(fā)展鋼筋加工商品化才能滿足建筑結構和工程新技術發(fā)展的需要，就是在這樣的背景下,我們即將設計一種適用于鋼筋鋼管多種加工的產品。黃 河 科 技 學 院 畢 業(yè) 設 計 (文獻翻譯） 第 2 頁在當今的建筑施工現(xiàn)場，工人一般使用的是機械式的鋼筋加工設備，這樣的設備不但占用的場地大，而且費力費時，同時沒有安全保護措施，極易造成工人的受傷；有些雖然占地少，但是工序繁雜，不能同時加工出所須的鋼筋用件，并且噪聲大，不宜控制，鑒于以上的情況，有必要設計一種有液壓系統(tǒng)統(tǒng)一提供動力的多功能鋼筋鋼管加工機械，可以適用于中小型建筑隊，該加工機動作方便靈活，便于掌握，移動，安裝簡便可靠。鋼筋切斷機是把鋼筋原材或已校直的鋼筋按配料計算的長度要求進行切斷的專用設備。廣泛應用于施上現(xiàn)場和構件預制廠剪切 6—40mm 的鋼筋。更換相應刀片，還可作為各種型鋼的下料機.切斷機的使用1．使用前的準備工作1.1 鋼筋切斷機應選擇堅實的地固安置平穩(wěn)，機身鐵輪用三角木楔好，接送料工作臺面府和切刀的刀刃下部保持水平，工作臺的長度可根據加工材料的長度決定，四周應有足夠搬運鋼筋的場地。1.2 使用前必須清除刀口處的鐵銹及雜物．檢查刀片應無裂紋，刀架螺栓應緊固防護罩應完好，接地要牢固，然后用于扳動帶輪，檢查齒輪嚙合間隙，調整好刀刃間隙、定刀片和動刀片的水平間隙以 0.5—1mm 為宜。間隙的調整，通過增減固定刀片后面的墊塊來實現(xiàn)。1.3 按規(guī)定向各潤滑點及齒輪面加注和涂抹潤滑油，液壓式的還要補充液壓油：1.4 起動后先空載試運轉．整機運行應無卡滯和異常聲響，離合器應接觸平穩(wěn)，分離徹底。若是液壓式的，還應先排除油缸內空氣，待各部確認正常后，方可作業(yè)。2．操作要點2.1 新投入使用的切斷機，應先切直徑較細的鋼筋，以利于設備磨合。2.2 被切鋼筋應先調直，切料時必須使用刀刃的中下部位、并應在動刀片后退時，緊握鋼筋對準刀口迅速送人，以防鋼筋末端擺動或蹦出傷人。嚴禁在動刀片已開始向前推進時向刀門送料，否則易發(fā)生事故。黃 河 科 技 學 院 畢 業(yè) 設 計 (文獻翻譯） 第 3 頁2.3 嚴禁切斷超出切斷機規(guī)定范圍的鋼筋和材料。一次切斷多根鋼筋時，其總截面積應在規(guī)定范圍以內。禁止切斷中碳鋼鋼筋和燒紅的鋼筋。切斷低合金鋼等特種鋼筋時，應更換相應的高硬度刀片。2.4 斷料時，必須將被切鋼筋握緊，以防鋼筋末端擺動或彈出傷人。在切短料時，靠近刀片的手和定刀片之間的距離應保持 150mm 以上，如手握一端的長度小于 400mm時，用套管或夾具將鋼筋短頭壓住或夾緊，以防彈出傷人。2.5 在機械運轉時，嚴禁用手去摸刀片或用于直接去清理刀片上的鐵屑，也不可用嘴吹。鋼筋擺動周圍和刀片附近，非操作人員不可停留。切斷長料時，也要注意鋼筋擺動方向，防止傷人。2.6 運轉中如發(fā)現(xiàn)機械不正常或有異響，以及出現(xiàn)刀片歪斜、間隙不合等現(xiàn)象時，應立即停機檢修或調整。2.7 工作中操作者不可擅自離開崗位，取放鋼筋時既要注意自己，又要注意周圍的人。已切斷的鋼筋要堆放整齊，防止個別切口突出，誤踢割傷。作業(yè)后用鋼刷清除刀口處的雜物，并進行整機擦拭清潔。2.8 液壓式切斷機每切斷一次，必須用手扳動鋼筋，給動刀片以回程壓力，才能繼續(xù)工作。為了保證鋼筋在混凝土結構中的相互連接，提高預制構件的強度。必須對鋼筋進行配胃，彎曲成設汁圖紙所要求的尺寸和形狀．這是鋼筋加工中一道重要的加工工序。因此．在鋼筋加工機械中，鋼筋彎曲機械同樣是重要的鋼筋加工設備之一.目前，為了更適應于建筑行業(yè)的發(fā)展方向，成功設計了一種液壓鋼筋彎曲切斷機，它是由液壓傳動和操縱的兩用機床，適用于加工直徑為 6—32mm 的鋼筋。這種彎曲機還可以進行切斷工作，是一種兩用機械，自動化程度高，操作方便，但不能同時進行切斷和彎曲兩項工作。該機械有一臺電動機帶動兩組柱塞式液壓泵，一組推動切斷用活塞；另一組驅動回轉液壓缸，帶動工作盤旋轉。同時，為了移動方便，機械底盤上裝有行走輪。但是這樣的兩用機械有一個缺點就是不能同時進行加工。黃 河 科 技 學 院 畢 業(yè) 設 計 (文獻翻譯） 第 4 頁鋼筋彎曲機的使用1 為適應鋼筋和中心軸直徑的變化，應在成形軸上加——個偏心套，用以調節(jié)中心軸、鋼筋和成形軸三者之間的間隙.2 根據彎曲鋼筋的直徑更換配套齒輪，以調整工作盤(主軸)轉速。當鋼筋直徑d＜18mm 時取高速；d＝18 —32mm 時取中速；d＞ 32mm 時取低速：一般工作盤常放在慢速上，以便彎曲在允許范圍內所有直徑的鋼筋。3 當彎曲鋼筋直徑在 20mm 以下時，應在插入座上放置擋料架，并有軸套，以使被彎鋼筋能正確成形。擋板要貼緊鋼筋，以保證彎曲質量。4 業(yè)前先進行空載試運轉，應無卡滯、異響，各操縱按鈕靈活可靠；再進行負載試驗，先彎小直徑鋼筋，再彎大直徑鋼筋，確認正常后、方可投入使用。鋼筋套絲機 即鋼筋螺紋連接設備的一種， 鋼筋螺紋連接設備和工具主要有鋼筋套絲機、量規(guī)、力矩扳手和砂輪鋸等。傳統(tǒng)的加上方法是手工在車床上扳牙，而手工扳牙最大的困難是定心難，對于大批量生產時，手工扳牙存在著勞動強度大、生產效率低、不安全等問題。為此，我們設計了一種扳牙自動定心套絲裝置。工作原理:將所用標準的扳牙放于調緊圈內(調緊圈的大小根據扳牙的大小由調節(jié)栓 )，用定位栓將扳牙鎖緊在調緊圈內。將套8的錐柄桿套于車床尾座內，固定尾座，車床正轉運廳了，搖動尾座手輪，扳牙白動定心，隨著工件轉動，殼體在套體內向左滑動，同時扭縮彈簧(彈簧由限位塊限位)進行扳牙。扳牙完成后，將車床反轉運行，在彈簧的反彈力作用下，殼體自動退出，完成扳牙。鐵屑從殼體上銑的一個落屑槽中落下。 由于調緊圈上銑有缺口，可以通過調節(jié)栓來調節(jié)其大小，所以此裝置可以用于扳不同規(guī)格的螺紋。它既解決了手工扳牙定心難的問題，又減輕了勞動強度，大大提高了生產效率。展望前景，隨著建筑施工機械化程度的提高，液壓技術和電子技術在鋼筋機械中加快應用，微機自動控制技術的逐漸普及，將使鋼筋機械自動化和半自動化的新面貌早日實現(xiàn)。畢 業(yè) 設 計文獻翻譯院 （ 系 ） 名

harming a person.For the sake of assurance reinforcing bar is in the concrete structure of link mutually, raise to prepare strength of make the piece.Have to carry on go together with to the reinforcing barStomach, the flection becomes to establish the size and shape that the juice diagram paper request. this BE, in the reinforcing bar that process to process a work preface together and importantly.Therefore.atThe reinforcing bar processes a machine in, the reinforcing bar flection machine the similarly important reinforcing bar process one of the equipmentses;Currently, for being adapt in a development direction of construct the profession more, success design a kind of liquid press the reinforcing bar flection to cut off machine, it is press by the liquid to spread to move and manipulate of two use tool machine, be applicable to process the diameter as the reinforcing bar with 6-32 mms.This kind of bent machine can be also carry on cutting off a work, is a kind of two use a machine, automation the degree is high, operation convenience, but can't be in the meantime carry on cut off and curve two works.That machine has a the set electric motor to arouse two sets of pillar fill type liquids to press a pump, a set of push cuts off to use piston;Another a set of drive to turn round a liquid to press an urn, arouse a work to hover around to turn.In the meantime, for moving convenience, have to run about a round on the machine bedrock.But such of two have a weakness with the machine be can't be in the meantime carry on process.The usage of the reinforcing bar flection machine1，In order to adapt the variety of the reinforcing bar and the central axis diameter, should add in taking shape stalk- the partiality set, regulate central axis,reinforcing bar and take shape stalk three clefts of in order to.2，According to the diameter of the flection reinforcing bar replace the kit wheel gear to turn by adjusting the work dish(principal axis) soon.When the reinforcing bar diameter d32 mms take low speed:General work the dish often put on slowly and soon, in order to flection all diametral in allow the scope of reinforcing bar.3，When curve the reinforcing bar diameter following in the 20 mm, should place to block to anticipate on inserting, also the stalk set with make curved reinforcing bar of quilt ability the exactitude take shape.Block the plank wants to stick tight reinforcing bar, curving quality by assurance.4，Homework the ex- forerunner go to get empty to carry to try an operation, should have no card ,the difference ring, each manipulate to press button vivid credibility;Carry on again a load to experiment, bend small diameter reinforcing bar first, then bend big diameter reinforcing bar, confirm a normal empress,the square can throw in an usage.Set of steel wireThe reinforcing bar set silk machine namely the reinforcing bar thread conjunction equipments of a kind of, the reinforcing bar thread conjunction equipments and tool mainly have the reinforcing bar set the silk machine,quantity the rules,the dint wrench and emery wheel saw etc..Plusing a method traditionally is a handicraft to pull a tooth on the lather, but the handicraft pull a biggest difficulty of tooth is fix mind difficult, for When the large quantity produce, the handicraft pulls a tooth to exist a labor strength big,produce an efficiency a low and uneasy and identically equal problem.For this, we design a kind of pull a tooth to fix mind a set of silk to equip automatically.The work principle:pull the standard use the tooth put in adjust a tight inside of circle(adjust the size of the tight turn according to pull the size of the tooth from regulate to bolt), bolting with the fixed position will pull the tooth lock tightly Be adjusting a tight inside of circle.Set of the awl handle pole set in the lather tail inside, fix the tail, the lather was transport hall, waving the tail the hand round, pulling the tooth white to move to fix mind, turning to move along with the work piece, the hull body at set left glide with introverted body, twist the spring coil(spring coil from limit piece the limit) to carry on pulling a tooth in the meantime.Turn over lather after pulling the tooth completion movement, under the rebound dint function of the spring coil, the hull body withdraws automatically, completing to pull a tooth.The iron scraps falls the scraps slot to decline a bottom from an of the hull body top . In order to adjusting to fence in to there is indentation tightly, can pass to regulate to bolt to regulate its size, so this device can used for the thread that pulls different specification.It since resolved handicraft to pull a tooth to fix mind a difficult problem, and then eased the labor strength, raised to produce an efficiency consumedly.Prospect foreground, along with construct the exaltation of[with] the construction mechanization degree, the liquid presses the technique and the electronics technique to speed an application in the reinforcing bar machine, the tiny machine controls automatically technical gradual universality, will make the reinforcing bar machine automate to automate and half of the new feature carries out soon.
