Choose Secondhand Scarifier Cutter

Scarifier cutter is a sort of conservation for the removal of pavement materials, machinery, high-speed rotation of the milling cutter drum and filled with milling method using inverse removed asphalt, cement concrete pavement. Due to the complexity of material composition, high hardness, wear a sharp knife makes the most rapid consumption of wearing parts, greatly boosting the construction costs. Therefore, the strengthening of the tools of research and rational use of 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 towards the milling drum, the knife block along with the screw fastening the bottom of the slot, while the cutter head knife inserted through the spring seat up. Segment from the tip, knife handles, gaskets, and spring up composition (Figure 2). Segment Cutting due to the finishing major tasks, tip materials, large particles of tungsten carbide alloy used from your soft cobalt metal will link it together and the hardness reached 1400HV above it at high temperature, high-impact cases, also consists of more good flexural and abrasion opposing force. And cone-shaped tip, top diameter is small, cut in the ground particular that the cone in the performance, reduced cutting resistance; tip in the bottom large diameter, providing protection against knife regulate. Corner by special brazing copper connected towards shank, relationship strength, can withstand the exerted on top of the knife's edge with the knife handle 45 degrees to the direction of 6 a huge amount of force generated by bending. Shank boasts a different upper and lower part of the mechanical properties, the upper half is not friction between road and milling wastes, which require high hardness, lower fifty percent of the rod into a knife block, the might want to be inside an absorb the impact of milling process, So, good hardness. This shank would desire to have a dual properties: wear and bending. Retract the middle there is often a slot, we use a knife clamp unloading through the cutter head pulled out a knife block (some Blade did not back a knife slots, use the Cutter punch out than me from the rear). Brand new Cutter, Shank head cloth also has grooves to increase friction at a time ground the actual rotation performance, to prevent partial put. Gasket is constructed of high-quality spring steel, shape in order to the disc spring, showing inverted spool. Its usefulness is twofold: First, reduce the wear and tear of a knife engine block. Segment work rotating seat whenever they are directly installed along the knife, knife block will definitely cause serious wear and tear, however the knife is much higher in comparison with price of Block Cutter, so to set up a gasket in between, so that rotation Segment only utilizing the friction pads to protect the knife block; Second, the cone-shaped seat of the gasket and knife cone positioning accuracy with leading to always make sure that the work of Segment in the knife block in a good right their state, reducing knife block Kong wear and tear. Spring up from the 1.2 mm high-quality spring steel is formed into a knife block knife block hole after strong tension, and the milling process does not block the prolapse using the knife. Milling process need to be able Segment rotation, it springs up one knife handle large radial clearance betwixt. Knife Block Old-fashioned milling machine must be used in welding a knife block, which could easy to replace, have now been using quick-change-type knife block, along with the set screws within the fixed base. 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 for quick maintenance. Base Base soldered directly to milling drum, in accessory for install additional tools, however a critical role - screw conveying. Large base your milling drum spiral arrangement, forming a Road 'spiral blade.' After milling the waste might be to rely on rotating 'spiral blade' are going to pushed into the milling chamber in the middle, soon after thrown through the plate throwing material. Therefore, the base shape and layout in the direct affect milling drum stacker, too as expected income effect, require special attention.
