Torsional shear wrench tight end primarily torsional shear type high strength bolts, its purpose is to torsional shear type high strength bolts Torx be interrupted. Work will be aligned with the bolt head wrench head, pull the switch to start the work, after a few seconds, Torx bolts will be broken, and then out of the Torx wrench to pull the trigger pop-up, that the end of the work. Torsional shear type high strength bolts tight early electric impact wrench can be used or set torque wrench, but you must use the tight end wrench torsional shear, torsional shear wrench is designed so tight end torsional shear type high strength bolts. Easy to operate, time-saving, safe and convenient. Note 1, the use of torsional shear wrench, should be balanced load slowly, the pressure must not be yanked and shoved torsional shear wrench, to avoid overloading the electric torsional shear wrench, causing misalignment of the output torque. After reaching the preset torque, should stop loading. 2, can not use the Preset torsional shear wrench to disassemble the bolt or nut. 3, is strictly prohibited in torsional shear wrench plus access trailing arm bushings extend supply torsional shear wrench, torque wrench to prevent damage. 4, be adjusted according to the desired torque, and confirm the adjustment mechanism in a locked state before use. 5. Preset torsional shear wrench use, it should be to the minimum torque, so that the full force of the spring to relax, to prolong its life. 6, avoid water intrusion Preset torsional shear wrench, to prevent corrosion of parts. 7, the choice of torsional shear wrench opening dimensions must be consistent with the size of the bolt or nut wrench opening is too large and easy to slip and damage parts of the hexagonal screw Jinan torsional shear wrench in the import car repair, you should pay attention to the metric wrench Select 8, selection principles of various types of wrenches, socket wrench generally preferred, followed wrenches, again open end wrench, adjustable wrench the last election. 9, in order to prevent damage and wrench slip, should be pulling in the opening thicker side, which is a larger force on the activities of the wrench in particular, should pay attention to prevent the opening of a "eight" shape, damaged nuts and wrench. A friction-type high connection requirements with face of tight joints, and with sufficient friction coefficient. When the combination of surface pattern design processing requirements are not specified, the following provisions deal with: The combination of high strength bolts blasting or shot blasting surface treatment to remove the surface rust, oil and other impurities, to Sa2.5 class standards roughness 50 ~ 75um, the friction coefficient of not less than 0.40. Drawings provisions, the execution by drawing regulations. 2.2 after treatment by high strength bolts connecting at the friction surface, should take protective measures to prevent contaminated dirt and oil. Prohibited in high strength bolt friction surface connections to make any mark. Stored in the factory, or in transport, to the custody of the installation site should pay special connection surface to prevent contamination. Pay particular attention to the protection of installed units feature friction surface cleanliness good strength bolts connecting the surface plate and the mother. Do not allow arbitrary webs connecting surface grinding machine grinding and maternal attachment surface.
