Service HotlineAn asphalt pavement screw, the asphalt pavement screw includes a main rod, an outer jacket, a pressing piece and a nut, the main rod is a columnar rod, the lower end of the main rod is provided with a table for supporting the outer jacket, and the middle part of the main rod passes through the outer jacket The upper part of the main rod is provided with a threaded section, the pressing piece and the nut are set on the threaded section, and at least two deformation holes are provided on the outer sleeve, and the middle part of the deformation hole is larger than the upper and lower sides of the deformation hole, The part between the adjacent deformation holes is the deformation part, and the width of the middle part of the deformation part is smaller than the width of the upper and lower sides of the deformation part. After the asphalt pavement screw of Guangdong Yueluo Hardware Industry Co., Ltd. is assembled, it has strong bonding force with the asphalt road. Even if it is hit, it will not be separated from the asphalt road. Using this asphalt pavement screw to fix the road railing can strengthen the road railing. The firmness of the assembly.
At present, due to the installation position determined in the design process of the traditional thrust cylinder in China, the corresponding position of the piston rod and the clamping arm is fixed, and it is impossible to ensure that the workpiece can be clamped while the workpiece is thin. It is not conducive to the use of such products when clamping. Secondly, when the workpiece is assembled or welded, it not only needs to be tightened in a certain direction, but also needs to be positioned, so as to ensure the accuracy required for processing. When a workpiece is fixed in this way, it must be realized by adding a mechanism, which will increase the complexity of the system and bring inconvenience to installation and maintenance.
Stainless steel screws, as the name suggests, must be made of stainless steel screw wire, and then screw the screw thread. Many of the properties of stainless steel screws are related to stainless steel. Taking into account the properties and organization of stainless steel, understand the properties of stainless steel materials and other aspects. Therefore, it is understood that stainless steel has good mechanical properties such as anti-rust, anti-corrosion, high temperature resistance, etc., then stainless steel screws also have these good mechanical properties. With the increasing quality of stainless steel materials. The mechanical properties of stainless steel screws produced by the screw industry are getting better and better. Anti-rust, anti-corrosion ability, and high temperature and high pressure are getting stronger and stronger.
Yueluo's thin plate rivet method, the thickness of the metal thin plate is less than 0.8mm. The convex rib extrudes the metal sheet adjacent to the rivet hole. The protruding rib is annular, and the protruding rib surrounds the rivet. The rivet head is provided with a positioning structure, the rivet head is provided with a positioning structure for docking the positioning structure, and the positioning structure and the positioning structure are mutually butted through the rivet to align the convex rib with the rivet
In the prior art, the screw suction device can be implemented in the following two ways. One is to use a magnet to magnetize the electric bit head, and the electric bit head is used to approach the screw, and the screw is stuck by the electric bit head, so that the function of picking up the screw can be realized; The vacuum generator is used to form a negative pressure in the screw guide groove, and the screw is sucked into the tube to realize the screw pickup. The disadvantage of this solution is that in the process of picking up the screws, the grooves of the screws cannot be aligned, which leads to the deviation or leakage of the screws. The disadvantage of this solution is that the screw with an aspect ratio of less than 1.8 is prone to suction and skew, and the stability is not high. It can be seen that the existing technology still needs to be improved and developed.
We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: rod motherboard copper column chassis studs, cap locking through holes, industrial automation nuts, high-foot hanging nuts and other products, we can provide you with suitable products Your fastener solution.
