German kohn spannwerkzeuge tools kohn spannwerkzeuge models kohn spannwerkzeuge prices

kohn spannwerkzeuge tools integrate hydraulic systems with conventional tools into a unified whole. They convert powerful hydraulic power into mechanical motions such as reciprocating linear motion, rotary motion, and orbital motion. A complete hydraulic tool system consists of five components: power elements, actuating elements, control elements, auxiliary elements, and hydraulic oil. Hydraulic tools include: hydraulic wrenches, electric pumps dedicated to hydraulic wrenches, hydraulic jacks, hydraulic bolt tensioners, hydraulic flange spreaders, hydraulic nut splitters, hydraulic pullers, etc. Hydraulic tools offer the advantages of high efficiency and convenience. A complete hydraulic tool system consists of five components: power elements, actuating elements, control elements, auxiliary elements, and hydraulic oil.

kohn spannwerkzeuge tool description

Lifting tools vary in application and construction, but all feature a hoisting mechanism that performs the basic lifting and lowering action. Materials can be lifted and lowered while suspended from flexible members such as wire ropes or lifting chains, or they can be raised by rigid members such as screws. Based on structural differences, lifting tools are categorized into light-duty lifting equipment, hoists, and overhead monorail systems. Light-duty lifting equipment mainly includes lifting pulleys, rigging, jacks, triangular chain blocks, electric chain hoists, and standard winches. Most are compact, lightweight, and simple to operate. Except for electric chain hoists, the majority are manually driven and suitable for applications with moderate workloads. They can be used individually or in combination. Some light-duty lifting equipment has substantial lifting capacity; for example, the lifting capacity of hydraulic jacks has reached 750 tons. Mine hoists and bucket elevators primarily perform vertical or near-vertical lifting and lowering movements along fixed paths. Overhead monorail systems utilize routes formed by rigid suspended rails, enabling material transport to various parts of a workshop and extending to areas outside the workshop.

1) Correct air supply system: The inlet pressure at the tool inlet (not the compressor outlet pressure) is generally 90PSIG (6.2Kg/cm^2). Excessively high or low pressure impairs tool performance and service life. The intake air must contain sufficient lubricating oil to ensure adequate lubrication of the pneumatic motor inside the tool (place a white sheet of paper at the tool exhaust to check for oil stains; the presence of oil stains is normal). The intake air must be free of moisture; using compressed air without an air dryer is inappropriate. 2) Do not arbitrarily disassemble tool parts before operation, as this compromises operator safety and causes tool damage. 3) If the tool malfunctions slightly or fails to achieve its original performance after use, do not continue using it; inspect it immediately. 4) Inspect and maintain the tool regularly (approximately once a week); apply Grease to rotating parts such as bearings, and apply Oil to the pneumatic motor. 5) When using various tools, strictly adhere to all safety regulations and operating instructions. 6) Select appropriate tools for the job; oversized tools easily cause work-related injuries, while undersized tools are prone to damage.

1) Set: The set is adjusted using a saw set. When setting, engage the slot of the saw set with the teeth and force them left or right. The degree of set must meet the requirements for the kerf. 2) Filing: When filing the teeth, clamp the saw blade in a vise so that the teeth protrude. Depending on the tooth size, use a triangular steel file 100–200 mm in length, filing each tooth from right to left. Apply uniform pressure with both hands. One face of the file should be held vertically against the lower cutting edge of the tooth, while the other face rests against the upper edge of the adjacent tooth. If the set of the teeth is irregular, place the saw blade flat on a steel plate and flatten all teeth with a wooden mallet, then reset and refile. Additionally, maintain the saw frame; if damage is found in cables, nuts, knobs, or wooden joints, adjust or repair them promptly.
