Characteristics of hardware mold manufacturing
The number of parts or quantities completed per unit time is several times, or even hundreds of times, the general processing method. In addition, the metal mold manufacturing process can be combined with the multi-chip, multi-process content in the mold to further improve production efficiency.
2, product quality is stable, strong interchangeability. Metal stamping is used to form the product. There are few factors affecting quality change and the risk is low. Some factors can be corrected by taking appropriate measures. The quality management can ensure the stability within the ideal range, thus effectively ensuring its interchangeability.
3. High material utilization rate Through a variety of stacking methods such as cross, tilt, multi-row, mixing, stacking, and uniform stacking, the material utilization rate can be improved and the material cost of the product can be reduced.
4, the material does not need to be heated. Generally, there is no need to heat the material during the metal mold manufacturing process. This can not only save energy, reduce heating equipment and space occupation, but also prevent the shape and size instability caused by the oxidation and deformation of the product surface caused by the heating furnace. In addition, it is possible to prevent an adverse effect of the temperature rise on the mold.
5. Improve the mechanical properties of stamping parts. Affected by the hardening phenomenon, the surface structure is dense, the hardness and wear resistance are increased, and the strength and rigidity are also improved.
The precision and error of metal mold manufacturing are terms for evaluating surface geometric parameters. Accuracy is measured by tolerance level, and the smaller the level value, the higher the accuracy. The processing error is expressed in numbers, and the number is large and the error is large. The machining accuracy is high, and the machining error is small, and vice versa. The actual parameters obtained by the processing method are inaccurate. In the function of the parts, as long as the machining error is within the tolerance range required by the part drawing, it is considered to ensure the machining accuracy.
All kinds of tools and products used in our daily production and life, the base of machine tools, the body shell, as small as an embryo head screw, buttons and the shell of various household appliances, are closely related to the manufacture of metal molds.
hardware mold manufacturing process performance:
1. Forgeable: hot forging has low deformation resistance, good plasticity, wide forging temperature range, less forging crack, cold crack and network carbide precipitation.
2. Annealing processing: wide range of spheroidizing annealing temperature, low annealing hardness, small fluctuation range and high spheroidizing rate.
3. Cutting: large cutting volume, small tool loss and low surface roughness.
4. Oxidation and decarburization sensitivity: high temperature heating has good oxidation resistance, slow decarburization speed, insensitive to heating medium, and not easy to produce pitting corrosion.
5. quenching: after quenching, the surface hardness is uniform and the hardness is high.
