● There are four types of screwing forms for Threaded fastener, which can be grasped with one screw, grasped with one screw, and grasped with one screw.
There are three forms of internal rotation for slotted nuts, which can be grasped with four screws and grasped with four screws. Only with 21 screws that can be grasped and lifted with 1 screw can the “hand help” be rotated; There is no difference.
What about the slotted nut without a stop wrench? Due to the large stop angle (note), it can only slip with a regular wrench and rotate the coupling with a hammer.
Hardware stamping parts are parts processed from steel or some non-ferrous metals, and the processing methods include cold/hot stamping, extrusion, rolling, etc. The processing methods include cold/hot stamping, die-casting, extrusion, etc.
Most precision machined hardware stamping parts require a long production time for structural stamping parts, and post-processing and other work still cannot meet the original requirements.
Hardware stamping parts are used in many places, such as electronic components, automotive parts, and can be seen in automobiles and other aspects.
The service life of stamping parts depends not only on the reasonable mold structure to manufacture hardware stamping parts with good precision, but also on the correct increase in the feeding ratio of the mold, otherwise it will cause waste products. The stamping of molds mainly depends on the reasonable precision of mold manufacturing, especially for precision stamping, casting, heat treatment, and precision stamping parts during mold stamping processing.
The stamping of the mold only requires 55% of the ejection, while some hardware stamping requires 10% of the thickness. Electrical parts should be made of stainless steel as much as possible, with smaller metal and alloy parts to reduce the amount of sheet metal used in the stamping process.
The cost of hardware stamping parts lies in selecting suitable blank products, rather than selecting blanks based on one’s own processing capabilities. The structural design of hardware stamping parts should not only make the blank produce larger size and weight, but also make the guide pillar and guide sleeve loose,
Hardware stamping processing refers to machine parts or components made from hardware, as well as some small hardware products. It can be used alone or as an assistive tool.
Furniture hardware mainly includes household appliances, kitchen equipment, and office supplies. For example, multiple home hosts, office desks, and ATM stop hardware products will be damaged, the plugs of home appliances will be severely worn, and large hardware radiators will be damaged,
The processing process of metal stamping parts includes blank, surface treatment, lathe processing, blade drilling, sharp angle rounding, spraying (electroplating, polishing), powder spraying, and other processes
