Geeignet für die schwere Schruppbearbeitung von Gussstahl mit großem Vorschub bei mittlerer und niedriger Drehzahl unter ungünstigen Arbeitsbedingungen.

(3) Special cold heading mold: Design and manufacture cold heading molds with special shapes according to specific product requirements

Main components and material selection of cold heading molds

1. Main components of cold heading molds: Cold heading molds mainly include upper and lower molds, mold cores, and mold seats. The upper and lower molds are used to clamp metal materials and complete the forming process through the clamping action, while the mold core is used to support and form the internal structure of the material.

2. Material selection for cold heading molds: The materials for cold heading molds need to have high hardness, high strength, good wear resistance, and fatigue performance. Common cold heading die materials include alloy steel

High speed steel, hard alloys, etc.

The manufacturing process of cold heading molds

1. Design of Cold Heading Mold: The design of cold heading mold needs to meet the technical and process requirements of the product, including the structural shape, dimensional accuracy, surface smoothness, etc. of the product. When designing, it is necessary to consider factors such as the strength, stiffness, and temperature changes of the mold.

2. Processing technology of cold heading molds: The processing technology of cold heading molds includes rough machining, heat treatment, precision machining, assembly, and debugging. Among them, heat treatment is crucial for improving the hardness, wear resistance, and fatigue performance of the mold.

The use and maintenance of cold heading molds

1. Use of cold heading molds: When using cold heading molds, it is necessary to select appropriate process parameters based on product requirements and mold characteristics, and strictly control the quality and dimensional accuracy of the forming.

2. Maintenance of cold heading molds: Cold heading molds require regular maintenance and upkeep during use, including cleaning and lubrication of the mold surface, repair of wear, and timely replacement of damaged parts.

Hard alloy molds mainly include the following categories

1. Wire drawing molds. This type of mold accounts for a large proportion in hard alloy molds, with main grades including YG8, YG6, YG3, etc

2. Cold heading die and cold stamping die. The main grades include YC20C, YG20, YG15, etc

3. Integral mold. The main grades of this type include CT35, YJT30, and MO15.

4. Non magnetic alloy molds. Mainly used for the production of magnetic materials。Grade such as YSN series YSN (including 20, 25, 30, 35, 40) and steel structure non-magnetic mold grade -TMF

5. Hot work molds. There is currently no standard brand for this type of mold, but market demand is increasing

general impact-resistant forging die

6. punching and shearing molds, as well as in large impact forming and stamping molds

stamping dies such as progressive dies.

7. In addition, there are some special types of molds, such as hexagonal molds, spiral molds and other non-standard molds etc.
