Product prices Comparison of domestic and cutting machine: As the cutter low-tech, easy to counterfeit, not the reasons for higher profits, so the manufacturers basically maintain the status quo for decades, the development of unpleasant, compared with foreign counterparts specifically the following aspects gap. (1) Foreign cutter eccentric shaft eccentricity larger, zhenghao jzr350 small drum diesel concrete mixer such as Japan vertical cutter eccentricity 24mm, while the domestic is usually 17mm. Seemingly and material, the gear structure is small, but, to bring trouble to the user, easy to manage. Because when cut by a small cut large expect material, not the tool change is to change the blade pad, and sometimes need to convert angles. Rack (2) foreign cutter are welded steel structure, parts machining accuracy, excellent roughness in particular, heat treatment process, the cutting machine had to bear the load, fatigue failure, wear, etc. more than made machines. (3) domestic cutter blade design is unreasonable, a single bolt, blade thin enough, 40 type and 50-type blade thickness are 17mm; and abroad are double-bolted, 25 ~ 27mm thick, so foreign blade in force overall performance and other aspects of life are more good domestic. (4) Domestic cutter cutting fewer times per minute. China is generally 28 to 31 times higher abroad 15 to 20 times, 30 times higher than the highest, higher working efficiency. (5) foreign models generally use the half-open structure, gears, bearings with grease lubrication, crank shaft, connecting rod bearing, red seat cutter, twist at hand plus oil lubrication. Domestic model structure fully open, fully closed, half open half closed three kinds of lubrication oil lubrication methods are focused on two kinds of splash lubrication. (6) Domestic cutter appearance quality, overall performance unsatisfactory; foreign manufacturers are generally scale production, willing to vote on the technical equipment The high level of automation, formed a complete system of quality assurance process. In particular, the appearance quality is excellence, cover one-time stamping molding, spray paint by the paint handling, color with a scientific and rational, not the outside where there are welds, burrs, sharp corners, the whole bright and clean. Some domestic manufacturers although production history is long, but not a scale, coupled with aging equipment, processing physical best sale js750 concrete mixer construction machine strength to fight, experience, production process consistent system for decades, so the quality of rough appearance, perception is poor. Method of operation (1) Transfer of materials and lower work surface should be kept horizontal cutter, table length can be determined according to the length of the workpiece. (2) Before starting, you should check to make sure no cracks cutter, turret bolt, solid shield. Then rotate the pulley by hand to check the gear meshing clearance, adjust the cutter gap. (3) to start, you should first dry run, check after each transmission parts and bearings in normal operation only after the job. (4) machinery does not meet the normal speed, the material can not be cut. When cutting, use the cutter, the lower parts of the alignment edge grip reinforced quickly put, the operator should stand on the side of force to suppress the fixed blade steel, should be reinforced to prevent the end of the pop-up hurt. It is prohibited on both sides of the blade with both hands holding the steel sub-leaning feeding. (5) Do not cut the diameter and strength than steel and red-hot steel mechanical nameplate. Once cut off when a plurality of reinforcement, the total cross-sectional area should be within the specified range. (6) cut low-alloy steel, replace the high hardness cutter, cutting machine plate diameter should be consistent with the provisions. (7) short-cut material, the distance between the hand and the knife should be maintained at 150mm or more, such as when hand side is less than 400mm, should be reinforced short sleeve or jig head pinched or folder in prison. (8) operation, is strictly prohibited by hand directly decapitation and remove debris near the cutter. Rebar cutter swing around and around, can not stay non-operators. (9) When they find machinery not functioning properly, good sale js500 widely used concrete cement mixer abnormal noise or skew cutter, you should immediately downtime. (10) job, should cut off the power, steel brush to remove debris between the cutter, carry out the whole cleaning lubrication. Ago (11) hydraulic drive type cutting machine operation, check that the hydraulic oil and motor rotation direction to meet the requirements. After starting, you should load operation, loose open valve, drain the body of the air cylinder net, before proceeding cut tendons. Front (12) Manual hydraulic cutting machine, oil drain valve should be tightened clockwise, after cutting is completed, it should immediately unscrew counterclockwise. Jobs, steady hand should be cut off the machine, and wear insulated gloves.
