First, the basic process of screw production
The production process of screws usually includes the following key steps: material selection, forming process, heat treatment, surface treatment and quality inspection. In this process, mold opening is an important link, especially in the molding process stage.
Second, the role of opening mold in screw production
Mold opening refers to making the corresponding mold according to the design requirements of the screw, which is used to form the head, rod and thread part of the screw. The purpose of mold opening is to ensure that the size, shape and accuracy of the screws meet the design requirements, thereby improving production efficiency and product quality.
In screw production, the opening die is usually divided into cold heading die and hot heading die two kinds. The cold heading die is suitable for the production of small screws and has the characteristics of high efficiency and high precision. The hot heading die is suitable for the production of large screws, with high toughness and strength.
Third, why do you need to open the mold?
1. Ensure dimensional accuracy: the mold can ensure the dimensional accuracy of the screw, so that it meets the design requirements. This is essential for the assembly and use of screws to avoid quality problems caused by dimensional deviations.
2. Improve production efficiency: Through mold opening, automatic production of screws can be realized and production efficiency can be improved. At the same time, the repeated use of molds also reduces production costs.
3. Easy quality control: The screw production after opening the mold has high repeatability and stability, which is easy to carry out quality control. Through the maintenance and adjustment of the mold, it is possible to ensure that the screws produced are always maintained at a high quality standard.
Four, how to choose the right mold?
When choosing a mold, the following factors need to be considered:
1. Screw type: Different types and specifications of screws require different types of molds. Therefore, when choosing the mold, we must first clarify the type and specification of the screw.
2. Material requirements: The material of the mold should have good wear resistance and toughness to ensure that it is not easy to damage during use.
3. Accuracy requirements: Select the right mold according to the accuracy requirements of the screw. High precision molds can ensure that the screws produced have high dimensional accuracy and surface quality.
