Hardware refers to various metal parts widely used in the machinery industry, mainly used in mechanical transmission, hydraulic transmission, automobile, railway, aviation, aerospace and other fields. The material used in the processing process of steel for hardware is mainly steel, because steel has good hardness, wear resistance, strength and toughness, and can withstand the ups and downs of strength and high-frequency repeated working state. Below, we will introduce the processing process of steel for hardware in detail.


First, steel cutting processing


Cutting is one of the most common and important processes in hardware processing. Mainly including turning, milling, drilling, planing, grinding and so on. Among them, turning is the most basic and most extensive cutting method, mainly used for processing cylindrical workpiece surface and hole processing. Milling is cutting on the surface of the workpiece with a tool, mainly used for machining flat and shaped surfaces. Drilling is the use of iron shell drill bits, drilling on the workpiece. Planing is the transverse cutting on the surface of the workpiece with a metal tool to achieve the purpose of machining the surface flatness. Grinding is the use of grinding machinery on the surface of the workpiece precision grinding, in order to achieve the requirements of processing accuracy.


Cutting is one of the most commonly used processing methods in the process of hardware processing, its main advantage is that it can quickly and efficiently process a variety of complex shapes of hardware parts, while ensuring the accuracy of parts, surface quality and dimensional accuracy.

Two, hardware forging processing


Forging is a commonly used metal forming process in the process of hardware processing, its main purpose is to compress metal materials through a large amount of application pressure to form. Forging process is mainly divided into cold heading and hot forging two kinds.


The main feature of cold heading is that it is carried out at room temperature and is mainly used to manufacture the heads of various fasteners and connectors. The advantage is that it can maintain the strength and accuracy of the material, and the disadvantage is that the processing efficiency is low.


Hot forging is to heat the metal material, and then add pressure and extrusion pressure to work the material into the desired shape. There are three methods of hot forging: free forging, forging under pressure and forging under extrusion. Among them, free forging is to place the metal material under the forging hammer head and process it with the impact force, which is often used to manufacture the square shaft and piston rod of the hardware. Forging under pressure is processed in the forging tool, which is often used to manufacture various wheel hubs, aircraft brackets, etc. Forging under extrusion is the use of extruder to extrude metal materials, which can produce various shapes of hardware parts.


Three, hardware sheet metal processing


Sheet metal processing is an important process in the process of hardware processing, mainly used to produce a variety of thin shell and sheet metal parts, including a variety of chassis, chassis and so on.


Sheet metal processing is usually divided into shearing plate forming, bending forming, stamping forming, deep drawing forming, reducing forming and other methods. Among them, shear plate molding refers to the cutting of metal plates through shear processing, which is often used to manufacture hardware shells and support structures. The bending forming type is the bending processing of the plate, which is often used for bending forming, folding forming and so on. Stamping molding is the use of punches to press the plate to form a variety of complex parts.


Deep drawing is the sheet metal stretching forming, mainly used to manufacture a variety of deep hardware parts. Reducing molding is the use of reducing the tube process to process the pipe into the required shape, often used in the manufacture of hardware pillars, shafts, etc.


In short, the processing of steel for hardware covers many areas, but its center is cutting, forging and sheet metal processing. In addition, the processing of hardware requires a lot of professional equipment and vocational skills, so professional processing manufacturers are required to process.
