Service HotlineAn elastic cylindrical pin assembling device, the assembling device includes an adapter handle, a punching needle, an elastic piece, a fixed sleeve and a telescopic sleeve, the adapter handle and the fixed sleeve are fixedly connected, and the punching needle is inserted into the adapter handle and fixed Inside the sleeve and its upper end is pressed against the adapter handle, the lower end of the punch needle is also inserted into the fixed sleeve and moves relative to the fixed sleeve in the up and down direction when the adapter handle pushes it to move up and down, the fixed sleeve A reset spring is also set between the punch and the punch, the lower end of the fixing sleeve has an insertion hole for the elastic cylinder pin, that is, a working cavity, and the lower end of the punch needle is also provided with a push fit for the upper end of the elastic cylinder pin. the positioning boss. When the elastic cylindrical pin assembling device is used, after assembling an elastic cylindrical pin, the elastic cylindrical pin needs to be re-installed into the fixed sleeve, which cannot realize continuous assembly and has low assembly efficiency.
The composition and proportion of this high-performance stainless steel screw thread are: 0.08%-0.15% C; 0.01%-0.60% Si; 0.02%-0.60% Mn; 0.01%-0.03% P; 0.002%- 0.03% S; 12%-14% Cr; 0.8%-1.5% Mo and the rest is Fe. The preparation method includes the following steps: smelting molten steel according to chemical composition requirements; hot rolling; annealing and pickling to obtain a stainless steel plate blank; coating and drying; cold drawing; cleaning and drying with a neutral activator; quenching; tempering ; coated and dried; drawn into stainless steel thread. This high-performance stainless steel screw line is energy-saving and environmentally friendly, with high corrosion resistance, high elasticity and high toughness. The preparation method and process are advanced and simple, and the production cost is low.
Self-tapping screw is a kind of threaded fastener that self-tapping and drilling the matching female thread in the pre-drilled hole of metal or non-metal material. When using self-tapping screw, a flat washer is often required to protect the fastening surface. Traditional When the self-tapping screw is used, the flat pad is easy to fall off, resulting in low work efficiency. In view of this, we propose a combined structure of the stuck self-tapping screw spring washer that prevents the flat pad from falling off.
At present, there are many kinds of smart terminals on the market. Due to the reduction of the overall volume of the smart terminal and the more compact internal parts, the nuts are generally made of injection-molded nuts. The traditional injection-molded nuts are directly fixed on the equipment. During the process, it is easy to loosen and fall off, which greatly reduces the service life of the injection nut and brings inconvenience to the use of the mobile terminal.
In recent years, more fasteners have been used in rivet nuts, which have replaced some existing welding methods to a certain extent. Rivet nuts are a way to join some difficult-to-weld equipment and other components. The use of rivet nuts requires rivet nut equipment (manual rivet nut equipment, etc.). Matters needing attention before using manual rivet nut equipment. 1. First, make sure the nozzle screws are properly assembled. According to the size of the rivet nut, select the appropriate equipment and rivet bolt. Every connecting part is not secure. 2. Confirm the deformation length or displacement of the rivet nut, and then leverage the long angle. 3. The scale ring of the rivet nut equipment is used to adjust the rivet stroke, which can be adjusted freely as needed. When adjusting the length of the rivet bolt, open the two handles and adjust the device head sleeve. The rivet bolts are exposed for a length slightly greater than the length of the rivet nut, which will eventually adjust the nut and device sleeve.
