Roller type metallurgy powder mixing device

Abstract

The invention provides a roller type metallurgy powder mixing device, and belongs to the technical field of powder metallurgy mixing equipment. The roller type metallurgy powder mixing device has the beneficial effects that a mixing bin of the roller type metallurgy powder mixing device and a center transmission shaft of a stirring structure can rotate synchronously, and metallurgy powder is turned over and mixed; a transmission gear I on the center transmission shaft is driven by a driving gear, a hollow cylindrical rotating shaft is connected to the center transmission shaft in a transmission bin in a sleeving manner, rotation of a transmission gear II is achieved by means of the driving gear, a driven gear A and a driven gear B, and the aims that even though the transmission gear I and the transmission gear II are not coaxial, the transmission gear I and the transmission gear II can rotate synchronously, and stirring rods on the center transmission shaft fully stir powder particles are achieved; and diameter ratios of the powder particles are more balanced, and mixing is more sufficient.

Description

technical field [0001] The invention relates to the technical field of powder metallurgy mixing equipment, in particular to a drum-type metallurgical powder mixing device. Background technique [0002] Powder metallurgy is a process technology for producing metal or using metal powder (or a mixture of metal powder and non-metal powder) as raw material, forming and sintering to manufacture metal materials, composite materials and various types of products. Powder metallurgy has similarities with the production of ceramics. Therefore, a series of new powder metallurgy technologies can also be used for the preparation of ceramic materials. Due to the advantages of powder metallurgy technology, it has become the key to solve the problems of new materials and plays a pivotal role in the development of new materials. [0003] In the previous process of powder metallurgy, the mixing of metal powder is related to the quality of the subsequent metallurgical process. When mixing, var...

AI Technical Summary

Problems solved by technology

The existing powder metallurgy production process generally prepares powder particles of suitable particle size first, then presses them into shape, and then sinters them to form parts with fixed shapes. The density and product performance after sintering are directly related to the size of powder particles. The requirements of the products are different, and powder particles of different particle sizes need to be uniformly mixed in different proportions to achieve the desired effect. However, the smaller particles of these powders tend to deposit downward during the transfer process. Due to the small particle size of the powder, the existing equipment is very difficult. It is difficult to achieve uniform remixing in proportion. The current mixing device is used to mix the powder. The mixing time usually takes about 3 hours. The long mixing time seriously restricts the mixing production efficiency
