Auto Accumulator Housing Cold Extrusion Blank Forging Moulds

Auto accumulator housing cold extrusion blank forging moulds
Product introduction:
Material: Q235
Process: reverse extrusion + shaping + reverse stretch + machining + finishing
Heat treatment: annealing
Product application: automobile energy storage system.

Process introduction:
Adopting cold forging technology, forming process by reverse extrusion and drawing, the product has the advantages of high precision, less turning allowance and strong mechanical performance, which is superior to the traditional hot forging process.

Features:
the product adopts multiple cold forging and finishing process, with high precision, good mechanical performance, high dimensional accuracy and stability. The reverse drawing process enables the product to reach the drawing size directly, eliminates the need for machining, and ensures the overall linearity of the flow.

The shape of the cold forgings is becoming more and more complex

Cold forging parts of the shape is more and more complex, from the initial stepped shaft, screws / nuts and catheter, to shape complex parts, such as motorcycles of different sizes spline axis and the spline sleeve, the typical process of spline shaft: extrusion rod - upsetting extrusion head - Intermediate spline; main process the spline sleeve is: anti extrusion Cup - bottom ring made - extrusion sleeve, such as car output shaft and the input shaft, and other cold forging products. For example, all kinds of automotive / motorcycle bevel gears, spiral bevel gears and other disc parts made by rolling rolling technology, such as cold forging parts and scroll supercharger produced by a Japanese company, has been listed in the national "fifteen" research project. At present, the cold extrusion technology of cylindrical gear has also been successfully used in production. In addition to the black metal, the cold extrusion of copper alloy, magnesium alloy and aluminum alloy material is becoming more and more widely used.

FAQ
Q:What is cold extrusion?
A:Cold extrusion is to put the metal blank in the cold extrusion die cavity. At room temperature, press the fixed punch on the press to make the metal blank produce plastic deformation, and make the processing method of the part.

A:1.to save raw materials
    2.improve production efficiency
    3.surface roughness is good, conducive to follow-up processing
    4.improve the mechanical properties of parts
    5.reduce the cost of parts
    6.environmental protection and energy saving
Q:Can three-dimensional exit by itself?
A:Sure.
