1.1Automatic wire straightening and cutting machine
Reinforcing steel cutting machine is a kind of shear of reinforced by the use of a tool. The general automatic steel cutting machine, and automatic steel bar cutting machine of. It is one of the essential equipment in steel processing, it is mainly used for buildings, bridges, tunnels, hydropower, large-scale water conservancy projects of steel cutting. Reinforcing steel cutting machine and other cutting equipment, has the advantages of light weight, low energy consumption, reliable work, high efficiency, so in recent years has been gradually mechanical processing and small rolling mill is widely used, in all areas of national economic construction play an important role.
The general automatic steel cutting machine, and automatic steel bar cutting machine of. Full automatic electric cutting machine is also called the electric energy is converted to kinetic energy by the motor control cutter incision, to achieve the effect of shear reinforcement. The semi-automatic is artificial control of incision, and shear reinforcement operation. But there is more to belong to the hydraulic steel bar cutting machine hydraulic steel bar cutting machine is divided into a charging and portable two categories.
Steel bar cutting machine
Applicable to all types of ordinary carbon steel construction, hot rolling bar, screw steel, flat steel, square steel cutting. Cut round: ( Q235-A ) diameter: (Φ 6-Φ 40) mm cut flat maximum specifications: (70x15) mm cut square: (Q235-A) the maximum specifications: (32x32) mm cut angle maximum specifications: (50x50) mm
Domestic and international comparison: because the cutting machine cutting machine technical content is low, easy imitation, profit is not high, so the manufacturer for decades to maintain the basic present situation, development is rapid, with foreign counterparts in particular has following several aspects the gap.
1) foreign cutting machine of the eccentric shaft of large eccentricity, such as vertical cutting machine eccentric distance 24mm, and general domestic17mm. seemingly saves material, some small gear structure, but to give the user to bring trouble, not easy to management. Because the cut the expected cut small material, not for a knife pad is for the blade, sometimes also need to change perspective.
2) foreign cutting machine frame is welded steel structure, precision machining parts and components, roughness especially heat treatment technology is excellent, so that the cutter under overload load, fatigue failure, wear etc. more than domestic machine.3) domestic cutter blade design is reasonable, the single screw bolt is fixed, the blade thickness is thin enough, type 40and type 50blade thickness is 17mm; and abroad are double bolt,25~ 27mm thickness, so foreign blade in stress and life are more domestic excellent comprehensive performance.
4) domestic cut machine cut fewer times per minute. Home is generally 28 to31 times, foreign higher than 15~ 20 times,30times the highest high, high work efficiency. 5) foreign models generally use the semi-open structure, gear, bearing grease, crank shaft, connecting rod, cutting knife holder, swivel by manual plus dilute oil lubrication. The model structure has fully open, fully closed, half open3, lubrication methods are concentration of dilute oil lubrication and splash lubrication of 2. 6) domestic cutting machine appearance quality, machine performance is unsatisfactory; foreign manufacturers generally is the scale of production, make investment in technology and equipment in
Into, automated production level is higher, form a complete set of quality assurance and processing system. Especially on the appearance quality is refine on, cover one-time stamping molding, paint the paint spraying processing, color collocation is scientific and reasonable, the appearance can not see where the weld, burrs, sharp corners, the bright and clean appearance. And some domestic manufacturers although production history is long, but not one of the formation of scale, and aging equipment, process, production technology experience to spell physical power, always make a few years, so the appearance of rough, perception of poor quality.
Reinforcing steel cutting machine safety requirements for operation
(1) to the surface of the work material feeding and cutter lower level, the length of the working platform can be processed according to material length.
(2) before, should check and confirm the cutter without crack, carriage bolts,

Its operating principles are: It use electric motors level triangle belt transmission and secondary gear transmission to slowdown. Then, it drives the crank rotate, The crank connected to slide block and moving blades in the slippery way make the back and forth straight line sport, makes the moving blades and the fixed blade shear and cut steel.
According to the working environment choice thetype of electric motors,using horizontal installation, protection of the electrical, squirrel-cage three-phase asynchronous motor.
momentum, and the scope of power, transmission efOption three slowdown,first level belt slowdown, followed by the secondary gear deceleration. firstthe introduction of automated, because it has a buffer, absorb shock and operate smoothly, small noise, and can protect the over loading. Then introduce a secondary gear deceleration slowdown, because gear transmission can be used to transmit arbitrary space between the two axis movement andficient transmission accurately, long using life, such as safe and reliable character. Power output by electric motors through slow down transmission system to import power to the executive body. As the system make rotation movement, The steel cutting machine needs the back and forth straight line sport ,in order to achieve this transformation, we can use c slider-crank institutions or gear and rack. I decided to consider realistic machinery.conditions using slider-crank as the executing.
1.2畢業(yè)設(shè)計中文文獻(xiàn)
鋼筋切斷機(jī)是一種剪切鋼筋所使用的一種工具。一般有全自動鋼筋切斷機(jī),和半自動鋼筋切斷機(jī)之分。它是鋼筋加工必不可少的設(shè)備之一,它主要用語房屋建筑、橋梁、隧道、電站、大型水利等工程中對鋼筋的定長切斷。鋼筋切斷機(jī)與其他切斷設(shè)備相比,具有重量輕、耗能少、工作可靠、效率高等特點(diǎn),因此近年來逐步被機(jī)械加工和小型軋鋼廠等廣泛采用,在國民經(jīng)濟(jì)建設(shè)的各個領(lǐng)域發(fā)揮了重要的作用。
鋼筋切斷機(jī)特點(diǎn):
一般有全自動鋼筋切斷機(jī),和半自動鋼筋切斷機(jī)之分。全自動的也叫電動切斷機(jī)是電能通過馬達(dá)轉(zhuǎn)化為動能控制切刀切口,來達(dá)到剪切鋼筋效果的。而半自動的是人工控制切口,從而進(jìn)行剪切鋼筋操作。而目前比較多的是應(yīng)該屬于液壓鋼筋切斷機(jī) 液壓鋼筋切斷機(jī)又分為充電式和便攜式兩大類。
鋼筋切斷機(jī)分類
適用于建筑工程上各種普通碳素鋼、熱扎圓鋼、螺紋鋼、扁鋼、方鋼的切斷。
切斷圓鋼:(Q235-A)直徑:(Φ6-Φ40)mm
切斷扁鋼最大規(guī)格:(70x15)mm
切斷方鋼:(Q235-A)最大規(guī)格:(32x32)mm
切斷角鋼最大規(guī)格:(50x50)mm
鋼筋切斷機(jī)行情
國內(nèi)外切斷機(jī)的對比:由于切斷機(jī)技術(shù)含量低、易仿造、利潤不高等原因,所以廠家?guī)资陙砘揪S持現(xiàn)狀,發(fā)展不快,與國外同行相比具體有以下幾方面差距。
1)國外切斷機(jī)偏心軸的偏心距較大,如日本立式切斷機(jī)偏心距24mm,而國內(nèi)一般為17mm.看似省料、齒輪結(jié)構(gòu)偏小些,但給用戶帶來麻煩,不易管理.因為在由切大料到切小料時,不是換刀墊就是換刀片,有時還需要轉(zhuǎn)換角度。
2)國外切斷機(jī)的機(jī)架都是鋼板焊接結(jié)構(gòu),零部件加工精度、粗糙度尤其熱處理工藝過硬,使切斷機(jī)在承受過載荷、疲勞失效、磨損等方面都超過國產(chǎn)機(jī)器.
3)國內(nèi)切斷機(jī)刀片設(shè)計不合理,單螺栓固定,刀片厚度夠薄,40型和50型刀片厚度均為17mm;而國外都是雙螺栓固定,25~27mm厚,因此國外刀片在受力及壽命等綜合性能方面都較國內(nèi)優(yōu)良。
4)國內(nèi)切斷機(jī)每分鐘切斷次數(shù)少.國內(nèi)一般為28~31次,國外要高出15~20次,最高高出30次,工作效率較高。
5)國外機(jī)型一般采用半開式結(jié)構(gòu),齒輪、軸承用油脂潤滑,曲軸軸徑、連桿瓦、沖切刀座、轉(zhuǎn)體處用手工加稀油潤滑.國內(nèi)機(jī)型結(jié)構(gòu)有全開、全閉、半開半閉3種,潤滑方式有集中稀油潤滑和飛濺潤滑2種。
6)國內(nèi)切斷機(jī)外觀質(zhì)量、整機(jī)性能不盡人意;國外廠家一般都是規(guī)模生產(chǎn),在技術(shù)設(shè)備上舍得投入,自動化生產(chǎn)水平較高,形成一套完整的質(zhì)量保證加工體系。尤其對外觀質(zhì)量更是精益求精,外罩一次性沖壓成型,油漆經(jīng)烤漆噴涂處理,色澤搭配科學(xué)合理,外觀看不到哪兒有焊縫、毛刺、尖角,整機(jī)光潔美觀。而國內(nèi)一些廠家雖然生產(chǎn)歷史較長,但沒有一家形成規(guī)模,加之設(shè)備老化,加工過程拼體力、經(jīng)驗,生產(chǎn)工藝幾十年一貫制,所以外觀質(zhì)量粗糙、觀感較差。
