Service HotlineThe embossing wheel is used to press the mesh pattern (rolling mesh pattern), and the middle is slotted. After milling, the thread still guarantees 6H accuracy. This knurled copper nut is used in power tools, which is different from other knurled copper nuts. The diamond pattern of this knurled copper nut is located in the middle section of the product, and the diamond-shaped mesh knurling wheel rolls the diamond-shaped flower along the large outer circular step surface.
On the other hand, when assembling many pin installation mechanisms, one end of the pin needs to be installed into the hole or arranged in the hole, and then the other end of the pin is applied to the pin through the pin installation mechanism, so that the pin is fixed in the hole. In the hole of the hole type product. This fixing method is not only extremely inefficient. And it is not possible to install multiple pins at once. Especially when exemplified at the other end of the pin, since there is nothing to hold the pin stable when the pin enters the hole type product, when force is applied to the other end of the pin, the pin can easily bend and damage the pin. .
screw is a tool that uses the physical and mathematical principles of the circular rotation and friction of an object to fasten the mechanism of the object step by step. A screw is a common term for fasteners, an everyday colloquial language. Screws are indispensable industrial necessities in daily life: tiny screws used in cameras, glasses, clocks, electronics, etc.; general screws in televisions, electrical products, musical instruments, furniture, etc.; as for engineering, construction, and bridges, large screws are used. Screws and nuts; transportation equipment, airplanes, trams, automobiles, etc. are used together with large and small screws. Screws have important tasks in industry. As long as there is industry on earth, the function of screws will always be important. The screw is a common invention in people's production and life for thousands of years.

The existing open-type blind rivets are widely used, usually composed of an iron rivet shell and an iron or stainless steel mandrel. During the riveting process, the open-type rivets are often unstable and biased due to the unsteady breaking force of the mandrel. When the foam is riveted, the nail head is directly pulled into the foam layer to damage the product structure. And there may be safety hazards such as scratching the operator during the installation process due to the exposed nail core. At the same time, due to the expansion of the rivet shell hole, the nail head will be loose inside.
In the switchgear of high and low voltage power equipment, the surface of many switchgear shells is painted or sprayed with plastic, and the installation beams and other parts of the switchgear and the entire cabinet must be continuously grounded according to the requirements of switchgear standards to improve the safe use of equipment. Because the common screw, spring washer, flat washer and nut type structural connection between the surface of the shell and the metal mounting beam cannot meet the requirements of grounding continuity, in order to meet the requirements, the surface of the shell is painted or Before spraying, special grounding studs must be welded. With the increase of installation beams, the number of welded studs must also increase, which increases the complexity of the product processing technology, wastes man-hours and increases costs.
