Choose Secondhand Scarifier Cutter

Scarifier cutter is a type of conservation for getting rid of of pavement materials, machinery, high-speed rotation of the milling cutter drum and filled with milling method using inverse removed asphalt, cement concrete pavement. Any the complexity of material composition, high hardness, wear a sharp knife definitely makes the most rapid consumption of wearing parts, greatly enhancing 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 for the milling drum, the knife block through 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 caused by the finishing of major tasks, tip materials, large particles of tungsten carbide alloy used by the soft cobalt metal will link it together and also the hardness reached 1400HV above it at high temperature, high-impact cases, also has a more good flexural and abrasion counteraction. And cone-shaped tip, top diameter is small, cut into the soil to make certain the cone into the performance, reduced cutting resistance; tip in the bottom massive diameter, providing protection against knife interact with. Corner by special brazing copper attached to the shank, the connection strength, can withstand the exerted on top of the knife's edge with the knife handle 45 degrees to the direction of 6 numerous force generated by flexing. Shank boasts a different lower and upper part of your mechanical properties, the upper half utilizing friction between road and milling wastes, which require high hardness, lower 50 percent the rod into a knife block, the need to be rrn a position to absorb the impact of milling process, So, good ruggedness. This shank would should have a dual properties: wear and bending. Retract the middle there is really a slot, home furniture use a knife clamp unloading from the cutter head pulled out a knife block (some Blade would not back a knife slots, use the Cutter punch out today from the rear). Some new Cutter, Shank head cloth also has grooves to increase friction a concern . ground the particular rotation performance, to prevent partial dress. Gasket created of high-quality spring steel, shape significantly like the disc spring, showing inverted spool. Its usefulness is twofold: First, reduce the wear and tear regarding your knife avoid. Segment work rotating seat if these directly that come with the knife, knife block is sure cause serious wear and tear, insurance policy coverage knife a lot higher in contrast to price of Block Cutter, so to a gasket in between, so that rotation Segment only the actual friction pads to protect the knife block; Second, the cone-shaped seat belonging to the gasket and knife cone positioning accuracy with top to ensure that the work of Segment in the knife block in the perfect right in the state, reducing knife block Kong corrosion. Spring up from the 1.2 mm high-quality spring steel is intended into a knife block knife block hole after strong tension, and the milling process does not block the prolapse at the knife. Milling process require to be able Segment rotation, it springs up light and portable knife handle large radial clearance between. Knife Block Old-fashioned milling machine is commonly employed in welding a knife block, it's just not easy to replace, have right now been using quick-change-type knife block, through the set screws within the fixed base. Screw open screws would be able to remove the knife restrict. Knife block installation area, effectively protecting the base and reduce stress. Open two instances the top ring groove, as the wear-lines for simple maintenance. Base Base soldered directly to milling drum, in accessory for install additional tools, an incredibly real a very important role - screw marketing. Large base in the milling drum spiral arrangement, forming a Road 'spiral blade.' After milling the waste through using rely on rotating 'spiral blade' are going to pushed in the milling chamber in the middle, then it thrown through the plate throwing material. Therefore, the base shape and layout on the direct impact on milling drum stacker, too as expected income effect, require special attention.
