1. Turning tool Generally uses the following types of turning tool tip: (1) Rough turning tool: It is mainly used to cut a large number of excess parts to make the diameter of the workpiece close to the required size. When rough turning, the surface finish is not important, so the tip of the turning …
The back of the polyurethane belt backing timing belt is used to bond and wrap the tensile element. It should have good flexibility and flex fatigue resistance, not easy to age, good oil resistance, and abrasion resistance, on the inner surface of the belt back A sharp-angled groove with an appropriate size can not only improve the flexural fatigue performance of the toothed belt due to process requirements, but also allow the intercepted air between the belt and the gear teeth to escape during operation to eliminate part of the noise.
Refers to the ability of a material to resist local deformation, especially plastic deformation, indentation or scratches. It is a measure of material softness and hardness.
The Preferred Path for eliminating hazardous conditions is to eliminate the hazard through improved design.
In the cutting process, the thin wall is easily deformed by the cutting force, which leads to an oval or a “waist shape” with a small middle and large ends.
Ancient machinery provides a new world for the development of human beings. With the continuous innovation and change of machinery, human ideas are also changing.
There are many reasons for the deformation of aluminum parts, which are related to the material, the shape of the parts, and the production conditions.
A set of reliable plastic mold design is mainly reflected in the quality of the molded plastic products (appearance quality and dimensional stability), convenient, rapid, and concise processing and manufacturing, which saves money and manpower, and leaves room for correction and improvement.
It is worth pointing out that no “lighthouse factory” has completed digital transformation alone. They all rely on partnerships to acquire or jointly develop new knowledge. And Microsoft has become the choice of many business partners.
The task of mechanical structure design is to draw a specific structure diagram based on the design task on the basis of the overall design conception, and to draw a specific structure diagram to achieve the functions required by the design.
Surface roughness Ra is a symbol often used by our machines. It is basically our old friend. If that drawing does not have it, it is estimated that the drawing will be scrapped. It is such a symbol for dealing with every day. Do you know why 0.8 is used , 1.6, 3.2, 6.3, 12.5, and not other numbers? I believe that members of the community have also encountered this confusion when they are learning and using it, but they have not studied the answer in detail. All of this must start with the great mathematics, and now I will explain it in detail.
Is it designed based on KKD (experience, intuition and courage) alone? Explain the advantages and necessary knowledge of tolerance design concisely and easily!
There are many transmission modes. Among the four major types of transmission methods (mechanical, electrical, hydraulic, and pneumatic) that are currently widely used, none of the power transmissions is perfect. Today I will share with you the comparison of the pros and cons of the 4 transmission methods.
The diaphragm compressor is determined by its structural characteristics. It is widely used to compress and transport various high-purity gases, precious and rare gases, toxic and harmful gases and corrosive gases. As an irreplaceable positive displacement compressor, it will follow the progress and development of science and technology and the people’s living standards. Continuous improvement will have more extensive applications. The main application areas of diaphragm compressors are: nuclear power, nuclear energy, food and medicine, petrochemicals, electronics industry, materials industry, national defense and military industry, and scientific experiments.
Stability is well understood, the ability to maintain or restore the original balance form under force. For example, the thin rod under pressure suddenly bends, the load-bearing thin-walled member folds, or the column of a building collapses. Today I will mainly talk about the understanding of stiffness and strength.
