Service HotlineWith the advancement of technology in various industries, the current structural design of screws has evolved from just simple locking to focusing on work efficiency during the locking process and not destroying the integrity of the objects to be locked. The new cases such as No. 556784 screw improvement and No. 289405 screw that integrates locking, stability, labor-saving, fast and multi-function which were previously designed and approved and published in the Central Taiwan Bulletin are the main representatives of screws. It is clear that It is learned that the two cases not only fully improve the shortcomings of the traditional simple locking screws, but also achieve the purpose of substantial improvement of the screws designed in each case in actual use.
Screw, some people call it screw [Screw] (screw), screw (screw rod). In fact, the screw is a general term, and the screw and the screw rod are different from each other. Screws are generally called wood screws to fasten wooden and plastic parts. The screw rod is a machine screw (machine screw), which is the kind of flat head at the front end. The pitch is small and uniform. It is generally used to fasten metal and machine parts. With the development of society, the materials for making screws are also various, and the functions of screws are becoming more and more diverse.
Riveting products provide great convenience for the unilateral connection of sheet parts, fast and efficient connection without bulky installation tools, and produce reliable standard internal and external threads, achieve cold installation after surface treatment, no pollution, is welding Effective alternative to nuts. Main applications: Auto-body, seat belt systems, bumpers, airbag systems, etc. 1. One-way drawing connection 2. Build standard internal and external threads 3. General product range: M3-M124. Materials: Carbon Steel, Stainless Steel, Aluminum 5. High quality air tools - efficient, economical, lightweight and easy to operate. Use the same principle as hand rivet nuts.
The slotted nut mainly refers to the hexagonal slotted nut, that is, the slot is machined above the hexagonal nut. It is used in conjunction with screw bolts with holes and cotter pins to prevent the relative rotation of the bolts and nuts, see GB6178 ~ 6181 and so on.
There are two typical pin shearing fixture tooling, among which the traditional fixture shown in Fig. 1 is more complicated and consists of fixture, spacer, washer and shearing block guide post, hardened bushing, shearing block and so on. The cylindrical pin is installed in the hardened bushing, and the axial load is applied through the shear block to complete the shear test. The fixture is complicated in manufacture and has many consumables, because the size of the hardened bushing is similar to that of the cylindrical pin. , and to keep the notch of the cylindrical pin upward, it is difficult to install before the test, and the broken cylindrical pin after the test remains in the hardened bushing and is difficult to remove.
