Tungsten steel mold processing is a process of shaping tungsten steel materials into the required shapes and sizes, and is widely used in various industrial fields. Tungsten steel is a kind of hard alloy, featuring high hardness, high strength, high wear resistance and high thermal stability, and thus is highly suitable for manufacturing molds. During the processing of tungsten steel molds, the following safety issues should be noted: 1. Prevent the hazards of tungsten dust and gases: Dust and harmful gases are produced during tungsten processing, which are detrimental to human health. Therefore, effective ventilation and protective measures should be taken, such as wearing dust masks and protective glasses, to ensure good ventilation in the working environment.
Mold processing refers to the processing of forming and blanking tools, and it also includes shearing dies and die-cutting dies. Under normal circumstances, a mold consists of two parts: the upper mold and the lower mold. Then, regarding various faults that may be encountered in precision mold processing, here are some troubleshooting tips: First, check the processing dimensional deviation and the cutting tool: Tool wear, damage or incorrect installation may cause processing dimensional deviation. Check the wear of the cutting tools and replace those that are severely worn in a timely manner. Make sure the tool is firmly installed and the cutting edge is sharp. Check the accuracy of the machine tool: A decline in the accuracy of the machine tool may affect the processing dimensions.
What should be noted when processing precision mold parts? 1. Choose equipment reasonably. The processing of precision mold parts mainly involves cutting off most of the machining allowance and does not require high-precision processed parts. Therefore, rough machining should have more power and high-precision machine tools, and relatively high-precision machine tools should be maintained during the completion process. Precision machine tools that can perform rough and finish machining on different machine tools, fully leveraging the equipment's capabilities and extending its service life. In the processing of precision mold parts, heat treatment processes are often arranged.
Mold accessories refer to the general term for metal parts specifically used on stamping dies, plastic molds or FA automation equipment in the mold industry. Mold accessories include: punches, punches, guide pins, guide sleeves, ejector pins, ejector cylinders, steel ball sleeves, oil-free guide sleeves, oil-free slide plates, guide pin assemblies, etc. When the wear-resistant blank undergoes plastic deformation in the mold cavity, it flows and slides along the cavity surface, causing intense friction between the cavity surface and the blank, which leads to the failure of the mold due to wear. Therefore, the wear resistance of materials is one of the most fundamental and important properties of molds. Hardness is the main factor affecting wear resistance.
(1) To ensure the processing accuracy of precision mechanical parts, it is best to carry out rough and finish processing of mechanical parts separately. During the rough machining of mechanical parts, the cutting volume is large, the cutting force and clamping force on the workpiece are significant, the heat generation is considerable, and there is a relatively obvious work hardening phenomenon on the machined surface of the mechanical parts. There is also a large internal stress inside the workpiece. If the rough and rough machining of mechanical parts is carried out continuously, the accuracy of the parts after finishing will be lost quickly due to the redistribution of stress. For some mechanical parts with high processing accuracy requirements.
