Special electric wrench for steel structure installation

    Steel structure is composed of steel materials, is one of the main types of building structures. The structure is mainly composed of beam steel, steel column, steel truss and other members made of section steel and steel plate, and adopts such derusting and anti-rust processes as silanization, pure manganese phosphating, washing drying, galvanizing and so on. Welds, bolts or rivets are usually used to connect each member or component. Due to its light weight and simple construction, it is widely used in large workshops, stadiums, super high-rise buildings and other fields. Steel structure is easy to rust, generally steel structure to rust, galvanized or paint, and regular maintenance.

     High-strength bolt connection is commonly used in steel structure engineering. High-strength bolt connection is also composed of bolt rod, nut and washer. High-strength bolt connection A special wrench is used to tighten the high-strength bolt and apply a specified pretension to it. The high-strength bolt connection mainly consists of large-hexagon high-strength bolt connection and torsional shear high-strength bolt connection.

     Fastening with electric fixed torque wrench for large hexagon high-strength bolt connection:

The nuts of large hexagonal high strength bolts are regular hexagonal, which is convenient for fixing with wrenches. For fastening large hexagon high strength bolts, an electric torque wrench is required. When the wrench fastens the large hexagon high strength bolts, the torque value shall be set in advance. When the wrench reaches the set torque value, the wrench will stop automatically.

     Fastening with electric torsional shear wrench for high strength bolt connection:

The twisted shear bolt is constructed with a twisted shear wrench, and the root USES the forward and backward torsion bar to clamp the screw itself directly through the "plum head", so there will be no turning during the application. The electric twist shear wrench will keep the cut plum head inside the sleeve after tightening, and then pull the trigger to pop the plum head out.

     Shandong OAK machinery industrial co., LTD., is set research and development, production, sales in the integration of professional electric tool manufacturers, the main products: electric  shear wrench, electric torque wrench detector, portable bolt torque, axial force torque, axial force, etc., after 20 years of innovation and development, the company now has 62 acres of industrial parks and 3 square meters production development workshop, introduced a large number of high-end processing equipment made in Switzerland, Germany, Japan, become large domestic production base of electric wrench.
