Summary of information:We have more than ten years of production experience in the screw industry. The main products are: hot-dip galvanized nu...

Further, the pressure riveting portion and the pressure-bearing portion are both columnar structures, the outer diameter of the pressure-bearing portion is larger than the outer diameter of the pressure riveting portion, the pressure riveting portion is a stepped structure, and the diameter of the lower end of the pressure riveting portion is smaller than that of the pressure riveting portion. The diameter of the upper end of the rivet part.

In the existing industrial technology field, screws are mostly used for the connection between components. For many electronic products, because the products are more and more thin and light, the connection between the shell and the shell is often affected by the thickness of the shell. , usually need to use screw column structure for connection. Take the existing outdoor three-proof mobile phone as an example: the screw column structure includes a shell, a shell and a screw, the shell is provided with a plurality of screw columns, and the nuts in the screw columns are injected through the in-mold injection process. Directly integrated with the housing. Due to the special use environment and use requirements of outdoor three-proof mobile phones, they need to have good high-strength anti-drop performance, while the three-proof mobile phones in the prior art are subjected to high-strength drop tests due to the fundamental stress concentration of the screw column. During the process, problems such as cracking of the screw column or breaking from the root occur.

In the process of automatically locking the screw to the product, there are only three types of screw supply mechanisms in the traditional automatic screw locking machine: 1. Magnet sucks for screws; 2. Vacuum sucks for screws; 7. Air blows for screws. The above three methods require long-distance screw supply, resulting in slow screw supply, low efficiency and high manufacturing cost. To this end, we propose an automatic locking screw machine that can directly supply screws.

Aiming at the shortcomings of the above-mentioned cabinets in the prior art that are assembled through hardware accessories, which affects the overall appearance, Yueluo provides a cabinet with a hidden screw-type installation structure and an assembling method thereof. The plate is fixed so that the screws can be hidden from the outside.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: pressure riveting nuts, cross flange bolts, black Torx bolts, anti-loosening serrated washers and other products, we can provide you with suitable tightening. Firmware Solutions.
