马鞍山华夏天宇机械有限公司是一家专业生产各种机械设备,刀具刃具,工程机械配件,矿山机械配件的厂家。

铣刨机刀头路面冷铣刨机是一种用于去除路面材料的养护机械，高速旋转且布满刀具的铣刨鼓采用逆铣的方式切除沥青、水泥等混凝土路面。由于路面材料成分复杂、硬度高，刀具的剧烈磨损使其成为消耗最迅速的易损件，大大增加了施工费用。因此，加强对刀具的研究以及合理的使用具有重要的经济意义。

  主要有刀头、刀座和基座组成。连接方式为：基座直接焊接在铣刨鼓上，刀座通过螺钉紧固在基座的槽里，而刀头则通过涨簧插入刀座。刀头由刀尖、刀柄、垫片和涨簧组成

由于要完成主要的切削任务，刀尖材料采用大颗粒的碳化钨合金，并由软性的钴金属将其连结在一起，硬度达到１４００ＨＶ以上，使其在高温、高冲击的情况下也拥有较好的抗折和耐磨性能。刀尖呈锥形，顶部直径小，确保切入地面时的锥入性能，减少切削阻力；刀尖底部直径大，提供对刀柄的保护。刀尖通过特别的铜钎焊连接在刀柄上，连接强度高，能承受施加在刀尖上，与刀柄成４５度方向的６吨力所产生的弯矩。
   刀柄上下部分有着不同的力学性能，上半部要与路面和铣刨废料产生磨擦，所以需要很高的硬度，下半部的杆插入刀座内，需要能吸收铣刨过程中的冲击，所以韧性好。这样刀柄就需要具有双重性能：耐磨且抗折。中间存在一个退刀槽，可以利用卸刀钳将刀头从刀座中拔出（有的刀头没有退刀槽，使用刀头冲杆将其从后部冲出）。一些新型的刀头，刀柄头部还布有凹槽，增加了与地面摩擦过程中的旋转性能，防止偏磨。
    垫片是由优质弹簧钢制成，形状类似碟簧，呈倒锥状。其用处有两个：首先减小刀座的磨损。工作时旋转的刀头如果直接安装在刀座上，势必给刀座带来严重磨损，而刀座的价格远高于刀头，所以要在这之间安装一个垫片，让刀头旋转时只与垫片发生摩擦，保护了刀座；其次，锥形的垫片与刀座的锥形定位面精确配合，保证工作时刀头在刀座中处于良好的对中状态，减少刀座孔的磨损。

Respect customer: First thanks fellow friends, the respect customer, the presence we the universe company, selects and purchases our product.
China Universe Machinery Limited company is a specialized production each kind of mechanical device, the cutting tool cutting tool, the project mechanical fitting, the mining machinery fitting factory
The mill digs machine tool bit road surface Xian to dig machine is one kind uses in removing the road surface material the maintenance machinery, revolves high speed also covers entirely the cutting tool the mill to dig the drum to use coagulation earthen road pavements and so on the up milling way excision asphalt, the road surface material ingredient complex, degree of hardness is high, the cutting tool fierce attrition causes it to become consumes most rapid vulnerable, increased the operating charges strengthens to the cutting tool research as well as the reasonable use has the vital economical significance.
Mainly has the tool bit, the tool apron and the base connection way is: The base direct welding digs on the drum in the mill, tool apron through bolt fastening in base trough, but the tool bit through rises the reed insertion tool bit by the knife point, the hilt, the filling piece and rises the reed to be composed
Because must complete the main cutting task, the knife point material uses the big pellet the carbon-tungsten alloy, and links by the soft cobalt metal it in the same place, degree of hardness achieved above 1400HV, enable it at high temperature, in the high impact situation also to have the good anti-booklet with the wear-resisting knife point assumes the cone-shape, the top diameter is small, guarantees cuts into when the ground the awl to enter the performance, reduces the resistance to cutting; The knife point base diameter is big, provides to the hilt the knife point through the special copper brazing connection on the hilt, the joint strength is high, can withstand the infliction on the knife point, becomes the bending moment with the hilt which 45 degrees directions 6 tons strength produce.
About the hilt the part has the different mechanics performance, the upper half must digs the waste material with the road surface and the mill to have the friction, therefore needs the very high degree of hardness, in lower part's pole insertion tool apron, needs to be able to absorb the mill to dig in the process the impact, therefore toughness is hilt needs to have the dual performance: Wear-resisting also anti- has a tool escape, may use unloads the knife pliers (tool bit which draws out from the tool apron has not to have the tool bit tool escape, uses tool bit rammer to run out it from behind).Some new tool bits, the hilt forehead also cloth has the scoop channel, increased with the ground friction process in, prevents the lopsided wear.
The filling piece is made by the high quality spring steel, the shape similar small dish reed, assumes but actually the use has two: First reduces the tool apron the work revolves if the tool bit installs directly on the tool apron, will inevitably bring the serious attrition to the tool apron, but the tool apron price will be higher than the tool bit far, therefore will have to install a filling piece between this, lets the tool bit will revolve when only with the filling piece have the friction, has protected the tool apron; Next, the cone-shape filling piece and the tool apron cone-shape locating surface home, guaranteed when work the tool bit is at good in the tool apron to the condition, reduces the tool apron hole the attrition.
