The Design of an Alloy Powder Workshop
The material particle size of metal powder sintering is an important factor affecting the performance of parts. When metal powder is pressed and sintered, deformation, shrinkage, cracking and other forming factors affect the performance of parts. Therefore, the powder workshop needs to do a good job in dust control.
The main content of the design of a metal powder workshop includes:
(1) Designing the layout of the workshop should make full use of the available space and be easy to manage and maintain.
(2) The workshop should lay out the production line in a reasonable manner to ensure production efficiency.
(3) The air supply and air extraction systems should be designed to meet the requirements of dust-free and dust-free conditions.
(4) Various dust collection equipment should be selected reasonably according to different production processes.
The workshop of metal powder sintering is a closed production space. In order to prevent dust from spilling out of the workshop, it is necessary to pay attention to the tightness of the workshop. At the same time, it is also necessary to consider the use of negative pressure, temperature, temperature and humidity control and other depth control measures, in order to make sure that the interior of the workshop reaches a certain level of dust-free and dust-free.
In the design of the metal powder workshop, the dust-free and dust-free requirements are also highlighted. The design of the dust removal system, in addition to the external air supply and air discharge systems, also includes a series of dust collection equipment. Examples of typical dust collection equipment include dust collecting bags, cyclone dust collectors, wet type dust collectors and electrostatic dust collectors.
The dust collecting bag is composed of a cloth bag and a dust frame, the operation is simple and the cleaning and replacement of the filter bag are very convenient. It is widely used in the dust removal process in powder processing workshops.
The cyclone dust collector is also a commonly used dust collection equipment. The dust collection is completed by air cyclone dust collector due to the centrifugal force generated by the air flow in the dust collection pipe. The dust particles with high dust concentration produced by powder processing can be effectively removed.
The wet type dust collector is a dust collection equipment that uses water as ash. The water performs the role of ash and dust, and the ash is trapped in the filter cloth. It is especially suitable for the treatment of sticky materials in powder processing.
Electrostatic dust collector is a dust collection equipment that uses the principle of electrostatic attraction. It is mainly suitable for the capture of particulate matter with small particle size and high concentration.
After the design of the metal powder workshop is completed, the corresponding safety and lighting equipment and instruments should be selected and installed. In addition, it is also important to design some auxiliary equipment for the powder workshop, for example, the production and storage of raw materials, such as sieves and hoists; powder packaging equipment; air and steam supply and drainage pipes; heating and cooling equipment; and fire-fighting equipment.
When the design of the metal powder workshop is completed, the relevant test should be carried out and the corresponding test report should be prepared. The production process flow and related data should also be fully recorded, including process parameters, daily output, quality and other data. During the operation of the workshop, the data should be continuously collected, analyzed and compared to ensure the correct use of the workshop.
In summary, designing a metal powder workshop requires professional knowledge and experience, in addition to ensuring the complexity of dust removal and ventilation, safety and comfort must also be taken into consideration. With the continuous development of powder sintering technology, the workshops design technology is constantly improving to meet the needs of production.
