With the development of the machining industry, there are more and more parts manufactured by cold work moulds in production, and more and more types of cold deformation moulds are used. Cold bulk die forging (cold heading, cold extrusion, embossing, etc.); sheet metal stamping (such as drawing, blanking, trimming, punching, etc.); material rolling (cold rolling, […]

Low-hardenability cold-deformed die steels are mainly carbon tool steels, especially high-carbon complex steels GCr15 and 9Cr2Mo. Among them, GCr15 bearing steel and 9Cr2Mo are used to make various forming wheels and cold rolls. GCr15 steel has good wear resistance, but poor hardenability and large quenching deformation. As a small cold roll (φ≤200m/m), it can be

The maintenance of standard parts of automobile molds is extremely meticulous work. Each damaged standard part of automobile molds needs careful maintenance and maintenance, so as to achieve our expected results and extend the service life of the mold. Punches and sleeves: most of the punches and sleeves used on the standard parts of automobile

Metal stamping die production process: Raw material processing: 1. Milling six face squares (perpendicularity error is not more than 0.1/300), the same mold material length and width dimensions can be the same, the thickness of 0.2mm grinding (requiring 0.5mm grinding of quenched parts); edge chamfer . 2. Grind the upper and lower planes (the workpiece

Mould is the basic process equipment of industrial production. The quality of the mould determines the quality of the product. Therefore, the mould is called the “mother of all industries”. The life of the mould refers to the number of products processed before being scrapped due to mould wear or other forms of failure under

In the stamping process of the die, sometimes it is inevitable that the processed parts will be damaged. How to prevent damage to the stamping parts of the mold? 1. The models, specifications and functions of the hardware fittings should conform to the current national standards and relevant regulations, and match the selection of plastic

When the above-mentioned defects occur in the mould parts, qualified fastener products cannot be formed, which will inevitably affect the production plan of the enterprise. Precaution In order to prevent early failure of the mould and effectively extend the service life of the mould, corresponding preventive measures are mainly taken from the following aspects. 1.

Cold heading mould is the most important process equipment in cold heading production, and it is the basis of cold heading processing, which directly affects the quality, production efficiency and safety status of cold heading special-shaped products. The basic composition of the cold heading die: the cold heading die is mainly composed of a feeding

Moulds have high requirements for materials, so the performance of mould materials should have the following points. 1. High wear resistance, if the mould is not wear-resistant, it is easy to cause excessive wear on the cavity. 2. High corrosion resistance, many plastic additives, such as flame retardants, and even the chemical action of the

Drawing moulding refers to a plastic forming method in which the processed material is reduced in cross-sectional area through a mould with a certain taper hole. Various geometric cross-section profiles can be formed through drawing moulding. It is an important method for preparing wires and pipes. . The characteristics of drawing processing are: it is

Because the failure of the drawing die is mainly adhesive wear and abrasive wear, and mainly adhesive wear. Therefore, the selected mould material must have high wear resistance and anti-adhesion performance, and sufficient strength. The selection should also consider factors such as the thickness of the sheet material to be drawn, the size and shape

What are the characteristics of precision mold manufacturing: 1. Wear resistance When the blank is plasticized in the mold type chamber, the surface of the cavity is flowing and sliding along the surface of the cavity, causing a severe friction between the cavity surface to the blank, causing the mold to fail due to wear.
