The Wedge anchor / Through bolt uses the slope of the trapezoid to exert a large amount of friction until the ideal fixing effect is obtained The material of fixdexWedge anchor / Through bolt is carbon steel and stainless steel. When it is used, it is set by the standard of expansion screws.Place the corresponding small holes, and then act out the expansion screw, it will have a very good fixing effect when the screw is working. Wedge Anchor / Through bolts are usually threaded on one side and tapered on the other. Wedge anchor / Through boltThe skin has a layer of galvanization, so that it all acts on the pre-set holes in the wall, and then tightened by the nut, which tightens the screws The outward action can apply the tapered side to the object. When the cylinder is fully opened, it is even fastened in the wall.
Wedge anchor / Through bolts are fasteners with a large contact area and high pull-out strength.
Mainstream products. The diameter of the partial column ring is smaller than that of the internal thread warp. Therefore, the pre-hole to be punched becomes smaller, which improves the construction efficiency. Also apply upward.
Working hours are convenient. Multi-position cold extrusion molding method of strong Wedge anchor / Through bolt, including cold extrusion when material is brokenIn the step of pressing the material, the diameter of the broken material is the same as the diameter of the rolling segment of the Wedge anchor / Through bolt.Cold extrusion processing: One or more cold extrusions make the upper part of the material part shrink, and the head forms a lead angle shape; one or more cold extrusions Pressure to make the tail of the material cold-extrusion compression rod into the shape of a striking head on a Wedge anchor / Through bolt;Make its head an inverted cone on a Wedge anchor / Through bolt. By reasonably delineating the working procedures, the present invention makes it necessary to adopt The car repair gecko can be manufactured by cold extrusion, with high speed, high accuracy, high production efficiency, and no traces of previous turning.Problems such as traces and expansion do not occur. Greatly save raw materials and reduce production costs. Moreover, cold extrusion improves the mechanical properties of the product, makingThe product has more advantages in using functions.The use of internal cones makes it difficult to lose the cones during construction and prevents it from falling off after construction. Machinable concrete, stone material. Applicable to electrical equipment engineering, piping engineering, air-conditioning pipeline engineering.
