Service HotlineNuts and washers are both small and medium-sized components of the tension reinforcement system, and they are easily lost on the construction site when used separately, which is not conducive to the storage management of turnover materials; 3) During the process of formwork support and removal, they must be installed individually And demolition, thus adding a construction process, affecting the efficiency of construction.
A low-carbon steel rivet nut fastener composed of a brim, a deformed skirt and a threaded wire hole is characterized in that there are fish teeth below the brim; the outer side of the lower end of the threaded wire hole has a chamfer; the inner wall of the threaded wire hole The cross section of the thread is an isosceles trapezoid, and the upper bottom of the trapezoid is a concave arc.
The advantages of Guangdong Yueluo Hardware Industry Co., Ltd. are that the rivet nut is fixed on thin-walled or thin-plate objects without welding, easy operation, high production efficiency, easy to manufacture, low cost, single-sided riveting, firm connection, no pollution, no noise, Has significant economic benefits.
Process equipment for aircraft production (hereinafter referred to as tooling) is directly used for part forming and component assembly. In order to satisfy the loading and unloading of aircraft parts and components during the use of the tooling, the tooling generally adopts a structural form that is easy to disassemble as a whole. In the field of aircraft process equipment manufacturing, positioning pins are usually used to connect and position the detachable parts of the tooling. At present, this kind of locating pin is divided into two types: direct pull-out locating pin and tie-suspended locating pin.
Generally speaking, combination screws are widely used in electrical, electric, mechanical, electronic, household appliances, furniture, ships and so on. But the above said that different combination screws have different functions. For example, Phillips pan head combination screws are generally used in small electronic products. Larger cross hexagon combination screws are used in larger electrical products, such as frequency converters, and some larger frequency converters use many cross hexagon combination screws. Hit the inverter case. To loosen the tightening effect. For example, two combination screws with flower teeth, which are used on the inverter, are used to break the paint, so that all the two combination screws on the surface of the casing are powered on. There is also a two-combination screw with a square pressure line, which itself is a two-combination screw with a pan head screw and a square pad. It is generally used on the surface of the terminal block. The function is for wiring and for crimping.
