Summary of information:We have more than ten years of production experience in the screw industry, the main products are: KM screws, hexagon so...

The connecting fasteners of the existing panel furniture are generally composed of pins, screws and nuts. When connecting two furniture boards, a nut must be placed in the hole first, then the screw is tightened, and then the pin is connected, which is not very convenient to assemble. Wood screws are generally used for fixing the existing concealed hinges, and the positioning is inaccurate, the installation is laborious and time-consuming, the labor intensity is high, and the work efficiency is low.

1. First remove the sludge on the surface of the broken head of the broken screw, use the center gun to kill the center gun of the section, and then use an electric drill to install a drill bit with a diameter of 6-8 mm to drill the hole in the center of the section, pay attention to the hole must be drilled through. After the hole is drilled through, remove the small drill bit and replace it with a drill bit with a diameter of 16 mm, and continue to expand and drill through the hole of the broken bolt. 2. Take a welding rod with a diameter of less than 3.2 mm and use a medium and small current to carry out surfacing welding from the inside to the outside in the hole of the broken bolt. Take half of the entire length of the broken bolt at the beginning of the surfacing welding. When starting the surfacing welding, the arc should not be too long. In order to avoid burning through the outer wall of the broken bolt, surfacing to the upper end face of the broken bolt, and then continue surfacing to weld a cylinder with a diameter of 14-16 mm and a height of 8-10 mm. 3. After the surfacing is completed, hammer the end face with a hammer to make the broken bolt vibrate along its axial direction. Due to the heat generated by the previous arc and the subsequent cooling plus the vibration at this time, the broken bolt and the thread of the body will be loose in between. 4. Carefully observe, when it is found that a small amount of rust leaks from the fracture after the knock, take the M18 nut and put it on the surfacing column head and weld the two together. 5. After welding, use a torx wrench to cover the nut while it is still hot, and twist it back and forth, or tap the end face of the nut with a small hand hammer while twisting back and forth, so that the broken bolt can be taken out. 6. After taking out the broken bolt, use a suitable tap to process the thread in the frame to remove rust and other debris in the hole.

The more complex inlaid embedded copper nut copper insert nut specification is M8, this copper insert nut is embedded in the injection molded part of the car, 5 twill embossing, 4 left twill embossing, 1 right twill embossing Knurling. Since there are multiple rolling patterns, double tool rests + double embossing rests are used, and 5 grooves and 2 chamfers are inserted at one time by a widening forming knife. The hot-pressed copper insert nut contains Reticulated and straight lines, the outer circle is conical, in the process of hot pressing to facilitate smooth introduction into the plastic hole.

Sprinkle the excess standard spring washer 7 on the positioning plate 12-1 on the spring washer positioning plate 2, and shake the spring washer positioning plate 2 by hand. After a short time, the spring washer 7 will be positioned and arranged on the upper positioning plate 12-1. In the upper spring washer hole 2-7, since the width of the opening groove 12-32 of the baffle plate 12-3 is smaller than the diameter of the spring washer hole 2-7, and the thickness of the upper positioning plate 12-1 is designed according to the thickness of the spring washer 7, Only one spring washer 7 can be accommodated in the spring washer hole 2-7 of each upper positioning plate 12-1, and the excess spring washer 7 is cleaned with a brush.
