With the increase of the mileage of expressway in China, the rapid development of urbanization, the increase of road reconstruction work in large and medium cities, the road cold milling machine as one of the main models of road maintenance projects, its advanced technical performance, High efficiency, simple construction methods, has been more and more attention by the construction unit. According to the engineering machinery industry statistics, at present, the number of cold milling machines used in our country is at least 3,500, and the number of 250-300 units is increasing every year. Domestic construction units have been out of manpower and milling machine difficult to choose the stage, now consider how to use the milling machine, looking for more efficient construction methods. China's road cold milling machine industry market prospects, milling machinery supporting parts and tools market promising.
Milling is one of the main consumables in the process of milling machines. The reasonable design and proper use of the milling teeth have an important effect on the working efficiency and construction quality of the milling machine. At present, the domestic cutting production enterprises on the milling teeth, especially the structural design of concrete milling teeth, cloth form lack of in-depth theoretical analysis, affecting the milling effect and picking and tooth seat life. Reference to foreign advanced drilling production enterprises of similar products, to develop design ideas, and thus improve product performance, to produce their own characteristics of the milling cutter will help.

Pavement Cold Milling Machine During the working process, the milling drum mounted on the lower part of the machine drives the milling cutter to rotate at high speed, and the pavement material is milled through the milling machine's own weight and mechanical forward movement. High-speed rotation of the milling cutter under the action of gravity and thrust with the milled pavement material produced a high contact stress, the contact stress reaches the limit, the pavement material is crushed and caving. With the linear motion of the milling machine and the rotation of the picks, the pavement objects are crushed and cradled alternately, thus completing the milling road work. Milling machine is usually in the alloy structure steel cutter body inlaid with carbide teeth, alloy teeth and steel cutter body with copper solder sink welding method for welding, and then re-quenching heat treatment and throwing Pills and other enhanced treatment process, made of good toughness of the cut. Pick-up alloy and trousers with steel material, as well as the structure and production process determines the use of picking performance. The accessory part of the pick includes a retainer sleeve, a preloaded gasket. The retainer is used to fix the picks and to ensure that the picks are rotated in use. Preloaded gaskets are easy to install and increase the rotation of the picks while protecting the outer surface of the picks from being worn. See the components of the picks.Road Repair Equipment - Doan Machinery
The following are the same as the "Alloy teeth are usually coarse grain tungsten carbide alloy, in the case of high temperature, high impact with good toughness and wear resistance, through copper brazing connection in the steel pants body. Milling teeth require a high weld strength, can withstand the application of the alloy teeth and knife handle at 45 ° angle, 6 tons of force generated by the bending moment and not fall off. At the same time, the upper and lower parts of the steel pants body also require different mechanical properties, the front and the road and milling waste material to produce friction requires a high hardness, the rear handle into the tooth socket, the need to absorb the milling process Impact energy, which requires better toughness. There is a reamer in the middle of the tooth, you can use the unloading pliers to pick out the pick from the tooth seat, there is no back to the groove can be used from the back of the punch directly out of the punch. Some of the cutting head is also equipped with grooves to increase the rotation performance with the ground friction process to prevent tooth picking.
Pre-pressure gasket made of high-quality spring steel, similar to the disc spring, was inverted cone. There are two uses: first to reduce the tooth wear. When the work of the rotating head if installed directly on the tooth seat, is bound to bring serious wear and tear to the knife seat, and the price of tooth seat is much higher than the pick, so to install a gasket between, so that when the rotation Only with the gasket friction, so as to protect the tooth base; Second, the cone of the gasket and the teeth of the tapered positioning surface with the exact work to ensure that the teeth in the tooth in a good alignment, The wear and tear.
geico flat tire commercial advantages of slotting machine for sale best pavement machineThe so-called synchronous gravel seal, is the use of special equipment that is synchronized gravel seal car and bonding materials (modified asphalt or modified emulsified asphalt) simultaneously spread on the road, through natural driving or tire roller rolling Single layer of asphalt gravel wear layer, he is mainly used as a pavement surface layer can also be used for low-grade highway surface construction. The simultaneous gravel seal concentrates the spraying of the binder with the aggregate process in a vehicle at the same time, allowing the gravel particles to come into contact with the sprayed adhesive immediately. At this point, due to hot asphalt or emulsified asphalt flow is better, can be buried at any time deeper into the binder. The simultaneous gravel sealing technology shortens the spacing between the adhesive spray and the aggregate spreading, increases the area of the aggregate particles and the binder, makes it easier to ensure a stable ratio between them, improves the work efficiency, Reduce the equipment cultivation, reducing the construction costs. Asphalt pavement after the treatment of synchronous gravel seal, the road has a good anti-skid performance and impermeability performance, can effectively cure the road lean oil, drop particles, minor cracks, rutting, subsidence and other diseases, mainly for the road Preventive and Reproductive Maintenance The simultaneous gravel sealer is used to synchronize the spraying of the asphalt binder and the spreading of the stone so that there is the most adequate surface contact between the asphalt binder and the aggregate to achieve the maximum between them Bonding of special equipment.Road Repair Equipment - Doan Machinery
Whether for road maintenance or as a transitional pavement, the performance of synchronous gravel seal is significantly better than other methods, thus greatly reducing the road maintenance and repair costs. On the original road disease repair role. After the road surface of the road surface of the small cracks, reticulate, lean oil, oil and so have a good repair effect. Short construction period. Sealing the road can be speed limit open traffic, ease the traffic situation, to ensure the normal use of the road. Construction process is simple, practical, wide range of applications. Reduce road maintenance costs. Compared with the traditional black road maintenance, synchronous gravel seal layer use efficiency is high, unit construction cost is low, can save 40% to 60% of the funds.
