Choose Secondhand Scarifier Cutter

Scarifier cutter is in other words conservation for the associated with pavement materials, machinery, high-speed rotation of the milling cutter drum and filled up with milling method using inverse removed asphalt, cement concrete pavement. Because of the complexity of material composition, high hardness, wear a sharp knife makes the most rapid consumption of wearing parts, greatly increasing style with a durable costs. Therefore, the strengthening of the tools of research and rational involving important economic significance. Tool Structure and Process Tool typical structure shown in Figure 1, mainly Cutter, knife holder and base composition. Connection as follows: base soldered directly for the milling drum, the knife block together with screw fastening the lower slot, protected cutter head knife inserted through the spring seat up. Segment from the tip, knife handles, gaskets, and spring up composition (Figure 2). Segment Cutting because of the completion of major tasks, tip materials, large particles of tungsten carbide alloy used with the soft cobalt metal will link it together as well as the hardness reached 1400HV above it at high temperature, high-impact cases, also rrncludes a more good flexural and abrasion resistor. And cone-shaped tip, top diameter is small, cut into the ground for the cone into the performance, reduced cutting resistance; tip in the bottom of large diameter, providing protection against knife handle. Corner by special brazing copper connected on the shank, rest and memory connect strength, can withstand the exerted on the knife's edge with the knife handle 45 degrees to the direction of 6 many force generated by tripled. Shank has a different lower and upper part of the mechanical properties, the upper half your friction between road and milling wastes, which require high hardness, lower a portion of the rod into a knife block, the will need to be able soak up the impact of milling process, So, good toughness. This shank would need for optimal dual properties: wear and bending. Retract the middle there is really a slot, turn out to be use a knife clamp unloading from cutter head pulled out a knife block (some Blade still did not back a knife slots, use the Cutter punch out with it from the rear). Innovative Cutter, Shank head cloth also has grooves to boost friction together with ground in rotation performance, to prevent partial buy. Gasket involves high-quality spring steel, shape similar into the disc spring, showing inverted cone. Its usefulness is twofold: First, reduce the wear and tear and tear of a knife street. Segment work rotating seat if it is directly attached with the knife, knife block is required to cause serious wear and tear, although knife significantly higher approach price of Block Cutter, so to set up a gasket in between, so that rotation Segment only however friction pads to protect the knife block; Second, the cone-shaped seat in the gasket and knife cone positioning accuracy with top to be sure that the work of Segment the actual world knife block in a superb right in state, reducing knife block Kong usage. Spring up from the 1.2 mm high-quality spring steel is made into a knife block knife block hole after strong tension, and the milling process does not block the prolapse through knife. Milling process reason to be able Segment rotation, it springs plan the knife handle large radial clearance between. Knife Block Old-fashioned milling machine is commonly employed in welding a knife block, discuss easy to replace, have now been using quick-change-type knife block, through set screws within the fixed socle. Screw open screws can easily remove the knife block. Knife block installation area, effectively protecting the base and reduce stress. Open two instances the top ring groove, as the wear-lines with regard to maintenance. Base Base soldered directly to milling drum, in accessory for install additional tools, fortunately there is a very important role - screw conveying. Large base in the milling drum spiral arrangement, forming a Road 'spiral blade.' After milling the waste usually rely on rotating 'spiral blade' will be pushed into the milling chamber in the middle, right after which thrown through the plate throwing material. Therefore, the base shape and layout of direct effects on milling drum stacker, as well as expected income effect, require special diligence.
