What is the Method of Cavity Cold Extrusion Press? A cold extrusion hydraulic press is a kind of equipment that implements the extrusion molding process. Mainly used for extruding and forging metal materials, such as upsetting, drawing, drilling, bending, stamping, plastics, etc. cavity cold extrusion press 1. Selection of cold extrusion press machine Cavity cold extrusion press generally uses a hydraulic press machine. The requirements for the hydraulic press machine are: good rigidity, accurate piston guide, and stable and reliable operation. At the same time, there must be a safety protection device to prevent the extrusion punch from breaking or the billet from being squeezed and splashing out to injure people. 2. Design and manufacture of extrusion punches The size calculation method of the cold extrusion punch is as follows: Its processing technology is: billet preparation → design and manufacture of punches → billet and punch surface treatment → die loading → extrusion

The aluminum alloy ball head is a kind of cue connecting piece, and its manufacturing process includes cold extrusion forming and forging forming. Following, we will introduce  hydraulic cold extrusion press  for aluminum alloy ball heads. Cold extrusion is a processing method in which the metal blank is placed in the cold extrusion die cavity, and at room temperature, the punch fixed on the press is applied to the blank to cause plastic deformation of the metal blank to produce parts.                                                  Working principle of  hydraulic cold extrusion press: 1. Material preparation: Prepare the aluminum alloy material to be extruded and cut it into an appropriate length. 2. Install the mold: Install the ball extrusion mold on the workbench of the hydraulic press, and make sure the mold is in a cold state. 3. Adjust parameters: According to the diameter and shape requirements of the ball head, set the parameters such as pressure, speed and time of the 200-to

Cold extrusion is a mechanical processing method that is mainly used to produce high-precision metal parts, including various parts such as bearings, gears, and shaft pins. This processing method is widely used in the machinery industry, and its ability to produce high-precision parts also plays a very important role in the metal processing industry. The oil storage tank of the automobile shock absorber is processed by this cold extrusion molding process.                                                       The technical process of cold extrusion of automobile shock absorber oil storage cylinder by  hydraulic cold extrusion press  is mainly divided into several steps: 1. Processing analysis: First, it is necessary to analyze the parts of the automobile shock absorber oil storage tank to be processed, and analyze the parameters of the material, structure and size of the parts to determine the design parameters of extrusion processing. 2. Manufacture of molds: According to the results o
