The two kinds of objects can be well connected together, mainly by the connection of parts between them, so this kind of parts has a general name, ANSI B18.2.1  There are many types and varieties of products, resulting in many ANSI B18.2.1 manufacturers being engaged in fierce competitions.  ANSI B18.2.1 manufacturers are constantly improving the quality of their products so as to attract a certain number of customers. do you know what is the manufacturing process of ANSI B18.2.1 manufacturers?

Process: wire pickling-annealing (wire can be drawn directly according to the difference of ANSI B18.2.1)-pickling (removing oxide scale, etc.)-drawing wire-forming on a cold header-rolling teeth on a tooth rolling machine-heat treatment (heat treatment is not generally performed for grades 6.8 and nuts below grade 8)-electroplating (according to customer requirements)-packaging-shipping

Cold heading: it is to use the plasticity of the metal and apply pressure or cold drawing with cold mechanics to achieve the purpose of solid deformation of the metal.  (Basic Definition)

Casting method of thickening the top of bar or wire at room temperature.  Cold heading is mainly used to manufacture bolts, nuts, nails, rivets, steel balls and other parts.  The forging stock data can be copper, aluminum, carbon steel, alloy steel, stainless steel, titanium alloy, etc., and the data utilization rate can reach 80-90%.  Cold heading is mostly carried out on a special cold heading machine, which is convenient for continuous, multi-station and active production.  On the cold header, the working procedures of cutting, heading, accumulation, forming, chamfering, thread rolling, diameter reduction and edge cutting can be completed in sequence.  The production efficiency is high, reaching more than 300 pieces per minute, and the diameter of the cold heading workpiece is 48mm.  The process of cold heading bolt implies that the figure is a typical process of cold heading bolt.  The multi-station nut active cold header is a multi-station nut active cold header.  The bar stock is actively fed to a certain length by a feeding organization, cut off by a cutting organization to form a blank, and then conveyed to a accumulating and overstock forming station and a punching station by a clamp for forming.

In fact, the current production technology level is relatively perfect, but this does not mean that there is no room to increase the demand for locks. In order to become a trustworthy Non-standard Bolt manufacturer, the development difficulties of non-standard bolt manufacturers on this road will continue to increase, which is also a test.
