Non-ferrous metal forging process

Forging is one of the methods of non-ferrous metal pressure processing and a link in machinery manufacturing. According to the different temperature states of metal materials during forging and working, forging can be divided into hot forging, warm forging and cold forging.

Application fields and specific cases of cold forging technology

Cold forging refers to placing a metal blank into a die cavity in a cold state, and under the action of a strong pressure and a certain speed, the metal is forced out of the die cavity to obtain the desired shape, size and certain mechanical properties. pieces. Clearly, the cold forging process relies on the die to control the flow of metal and the mass transfer of the metal volume to form the part. It is an important part of precision plastic volume forming technology.

Causes of cracks in precision forgings

(1) Surface cracks are caused by over-burning or overheating of the billet due to excessive forging temperature or excessive hammering speed. The crack is wide, the fracture is uneven, and the structure is coarse and dark gray. In the low magnification structure, the crack end is zigzag,

Description of materials and processes suitable for cold forging

Cold forging is a process carried out at room temperature or slightly warmer and can be used for most materials, provided that the die is designed to be strong enough to withstand the stresses created by forging. Metals that can be forged are lead, tin, aluminum alloys, copper, titanium, molybdenum, vanadium, and steel. Examples of cold forged parts are collapsible tubes, aluminum cans, cylinders, gear blanks.

Introduction to the process characteristics of forging and pressing by non-ferrous metal forging and processing manufacturers

Modify metal structure, metal function. After the ingot is hot forged, the original as-cast looseness, pores, micro-cracks, etc. are compacted or welded; the original dendrites are broken to make the grains finer; at the same time,

What are the effects of die accuracy of non-ferrous metal forgings

Die structure has a certain influence on the quality, productivity, labor intensity, service life of forging dies and processing and manufacturing of non-ferrous metal forgings, and its importance is no less than the design of various die chambers. In order to fill the forging well and to balance the stress in all parts of the die,

What are the characteristics of cold forging and ordinary forging

First of all, you need to accurately calculate the size of the original billet, and strictly according to the quality of the billet blanking, otherwise it will increase the dimensional tolerance of precision die forgings and reduce its accuracy. It is also necessary to carefully clean the billet surface, removing all scales on the billet surface, and other defects such as decarburized layers.

Copper, silver... hammers in non-ferrous metal forging

There are two types of tools: casting and forging. Forged ones are better. In some large tool manufacturers in Europe, forged English will be marked on the tools.

Cold forging process and process classification

Cold forging technology belongs to volume plastic deformation at room temperature. Using the die installed on the press, under the action of a considerable unit extrusion force and a certain speed, the metal is plastically deformed in the die cavity, so that the blank becomes the desired Shape, size and parts with certain properties

The advantages of precision forgings

Precision forgings are metal parts that can be plastically deformed into the shape of the part, engineered to a certain tolerance, and a blueprint configuration that can be obtained with little, if any, subsequent machining. They feature 0- and 1-degree draft angles, thin cross-sections, tight tolerances, tight radii, and good surface conditions. Precision forgings of aluminum and titanium usually have multiple parting lines, which can be projected horizontally or vertically, while achieving better grain flow control
