Hardware mold manufacturing can be based on different product characteristics and needs to design the corresponding mold, they have different structure and function, the production of different products. Today, Xiaobian will introduce the characteristics of hardware mold manufacturing and the knowledge of processing accuracy and error in detail.
Characteristics of hardware mold manufacturing
1, production efficiency unit time to complete the number of parts or engineering is the general processing way several times, even hundreds of times. In addition, the metal mold manufacturing process can be combined with the mold of multi-chip, multi-process content, further improve the production efficiency.
2. Stable product quality and strong interchangeability. Metal stamping is used to form products. There are few factors affecting quality change and low risk. Some factors can be corrected by taking appropriate measures. The quality control can ensure the stability in the ideal range, so as to effectively ensure its interchangeability.
3, high material utilization rate through cross, tilt, multi-row, mixing, stacking, uniform stacking and other stacking methods, can improve the utilization rate of materials, reduce the material cost of products.
4. Materials do not need heating. Generally, heating materials are not required during the manufacturing of hardware molds. This can not only save energy, reduce heating equipment and space occupation, but also prevent the product surface oxidation and deformation caused by heating furnace shape and size instability. In addition, it can prevent the adverse effect of rising temperature 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 stiffness are also improved.
The precision and error of metal mold manufacturing are terms to evaluate the geometric parameters of the surface. Accuracy is measured by tolerance grade. The smaller the grade value, the higher the accuracy. Machining errors are represented by numbers, large numbers, large errors. High machining accuracy, small machining error, and vice versa. The actual parameters obtained by the processing method are not accurate. In the function of 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, body shell, as small as an embryonic head screws, buttons and the shell of various household appliances, are closely related to hardware mold manufacturing.
Hardware mold manufacturing process performance:
1. Malleable: low deformation resistance in hot forging, good plasticity, wide forging temperature range, less forging crack, cold crack and mesh carbide precipitation.
2, annealing processing: spheroidization annealing temperature range is wide, annealing hardness is low, fluctuation range is small, high spheroidization rate.
3, cutting: large cutting amount, small tool loss, low surface roughness.
4, oxidation and decarburization sensitive: high temperature heating oxidation resistance is good, slow decarburization speed, not sensitive to the heating medium, not easy to produce pitting.
5, quenching: after quenching surface hardness is uniform, high hardness.
