What is the difference between cold forming and hot forming of mechanical materials, and what materials are mainly processed

by admin

the difference between cold forming and hot forming of mechanical materials: forming is mainly for forging. Forging forming of workpiece blank in the state of no heating is cold forming, and forging forming in the state of heating is hot forming. Hot forming is divided into warm forging and hot forging, with different temperatures. Not only stainless steel, but also other materials when forging. It is mainly used to process steel parts
cold forming is the processing method of punching, shearing, bending and stretching materials without heating. Cold forming processes include cold heading, cold rolling, die forging, etc. The main advantages of cold-formed steel structure: 1. Compared with thicker hot-rolled section steel, cold-formed steel can be processed into smaller load and shorter span. 2. Through cold forming, the unusual section shape can be obtained economically and the satisfactory strength weight ratio can be obtained. 3. Considering the tight type of packaging and transportation, nested sections can be produced. 4. There is no expansion and deformation under the action of environmental gravity
a special plastic processing method for processing thermoplastic (see thermoplastic resin) sheets into various products. The sheet is clamped on the frame and heated to a softened state. Under the action of external force, it is close to the mold surface to obtain a shape similar to the mold surface. After cooling and shaping, the product is finished after trimming. This process is also used for rubber processing.

cold forming: it refers to changing its shape at room temperature, such as stamping and cutting. Material Science; Metal, plastic
thermoforming; Is to heat the material to its melting point and turn it into a liquid, which is made with a fixed mold; Aluminum alloy, magnesium alloy, steel making, plastic, etc

generally, the quality of cold forming is high, and the cold steel plate

suppose you are talking about metal material forming process:
first of all, cold forming is what we often say about stamping, cold heading, etc. sheet metal processes are most commonly used, such as case forming, electronic plug-in forming, etc. Cold heading: more common processes such as handle and screw
secondly: hot forming is what we often call hot forging,
1 Generally, machining parts with complex shape and certain requirements for mechanical properties. For example: slider, joint, pin, etc
2. Generally, the hot forging process is used to process large parts that are difficult to machine. It is a common large-scale equipment in iron and steel plants and large machinery plants

main processing materials:
cold forming materials: thin sheet metal parts. The materials have certain ductility, that is, good plasticity and low strength, so as to prevent cold processing cracking or internal cracks
thermoforming material: good thermoplastic. For details, please refer to the specification of hot work die steel in the mechanical design manual.

cold forming and hot forming are mainly for forging. Forging forming of workpiece blank in the state of no heating is cold forming, and forging forming in the state of heating is hot forming. Hot forming is divided into warm forging and hot forging, with different temperatures. This is also true when forging other materials, not only stainless steel

generally used to process steel parts
