Tungsten steel square hole tensile mold is a precision mold specially designed for processing square holes or other special structures. Its design and manufacture combines the high performance of tungsten steel materials with special processes. The following is a summary of relevant information about the comprehensive search results:
1. Material selection and characteristics
1. **Material Advantages**
Tungsten steel (carbide) is made of a mixture of tungsten and steel, with the highest hardness (HRA 88-93), the highest wear resistance, the highest corrosion resistance and the highest high temperature stability, suitable for high-strength stretching scenarios. Commonly used brands include YG8, YG15, etc., which are suitable for stretching and forming materials such as stainless steel, copper, aluminum, etc.
2. **Performance Considerations**
- **Hardness and toughness balance**: High hardness ensures wear resistance, while appropriate toughness reduces the risk of impact fracture.
- **Thermal Conductivity**: The good thermal conductivity of tungsten steel helps to quickly dissipate heat and reduces thermal deformation of the mold.
2. Manufacturing process
1. **Core Steps**
According to the process description of web pages 1 and 6, the machining process of square hole stretching die usually includes:
- **Structural Design**: Design mold cavity, mold release mechanism, etc. according to square hole size.
- **Material Cutting and Rough Processing**: Cut tungsten steel and perform preliminary molding.
- **Heat treatment and finishing**: The inner wall of the square hole is processed through high-precision processes such as wire cutting and electric spark processing to ensure dimensional accuracy (the tolerance can be controlled at ±0.002mm).
- **Surface treatment**: Polish to mirror finish to reduce material adhesion; some molds require CVD coating to enhance wear resistance.
2. **Assembly Process**
The assembly of square hole molds requires special treatment:
- Use interference fit to inlay the tungsten steel die into the die sleeve, and gradually align the end faces through stamping to ensure concentricity.
- Multiple coating and assembly cycles to avoid deformation and improve life.
3. Advantages and applications of molds
1. **Performance Advantages**
- **High precision**: can process mirror-grade mold holes to ensure product surface finish.
- **Long life**: The wear resistance is more than 5 times that of ordinary molds, especially suitable for large-scale production.
- **Low coefficient of friction**: Reduce tensile resistance, improve efficiency and reduce energy consumption.
2. **Application Area**
Widely used in industries such as stainless steel tableware, electronic communication shells, automotive parts (such as engine parts), etc. that require high-precision square hole molding.
4. Maintenance and customization
1. **Maintenance points**
- Clean the mold regularly to avoid dust or corrosive media residues.
- Avoid overload use and repair worn parts in time to maintain accuracy.
2. **Customized Service**
Our company supports customization of the map and adjusting mold structural parameters according to customer needs.
