The wire-cutting method is used for the hole processing and shape processing of the cavity and template of the plastic mold. The technology of wire cutting is used to replace the electrode with a metal wire for electrical discharge machining. The wire material generally uses brass (alloy of copper and zinc). In addition, there are…
There are many types of inverted buckles for the flow channel locking shape of the point gate structure, and the type shown in Figure 1 is generally used. The type in Figure 1 is a method in which a pull pin with an undercut shape on the head is arranged at the root of the…
The basic knowledge of thermal expansion of plastic mold parts is explained. In order to maintain the proper surface temperature of the mold core, plastic molds are generally insulated at a temperature of 30 to 150°C. Other parts, such as sprue bushes, runners, and the parts where the molten resin flows in, will receive the…
Molding or molding manufacturing process to form a liquid or soft raw material using a rigid frame called a mold or matrix. This in itself may already use a pattern or the final object of the model. The mold or mold is a hollow block filled with liquid or soft materials such as plastic, glass, metal,…
The shrinkage of plastics is mainly due to the shrinkage of the volume, the surface raw materials at the thickness of the wall are pulled in, and dent marks appear on the surface of the finished product during chemical conversion. Shrinkage is the most common undesirable phenomenon that occurs on the surface of the finished product….
As a novice of simple conveyor belt equipment, often appear troubling deviation problem, because I have done several belt conveyor before (ordinary belt conveyor, electric roller belt conveyor, telescopic lifting belt conveyor, etc.), now I sum up the experience to share. Opening: transport equipment is now one of the equipment can be seen everywhere, can…
Calculate the air consumption of pneumatic actuators and the amount of air required. It can be used to control the amount of air used and select the size of components such as pressure reducing valves. Air consumption/required air volume calculation software: https://www.smc.com.cn/select/accs/zh-cn/index.html Calculation steps: 1. Select the calculation item air consumption/required air volume (flow rate )…
Some common problems and solutions in the assembly, debugging and use of laser cutting gas circuit are as follows: 1. When the laser cutting machine is cutting stainless steel plates, the actual value of the oxygen pressure provided by the air supply system is 1.5mpa, which exceeds the normal use range (0-1.0mpa) of the conventional…
Fully automatic palletizing manipulator, also known as palletizing robot, is a kind of high-tech servo robot developed under the background of modern industrial development. Using its flexible and changeable working environment and working time, it can be used in any environment. And a masterpiece of modern high-tech means that can work normally at any time….
The technical requirements for mechanical drawings (including parts drawings and assembly drawings) in “basic requirements for product drawings and design documents drawings” can be roughly divided into the following five aspects.
In order to earn more money, there are many black heart merchants who charge old bearings well, recycle some used or unused old bearings and buy them as new bearings after treatment.
The purpose of disassembly is to facilitate maintenance. As the structure of mechanical equipment has its own characteristics, there are differences in the weight, structure, precision and other aspects of parts. If the parts are disassembled improperly, they will be damaged, causing unnecessary waste, or even unable to repair. In order to ensure the quality…
Surface treatment is a process of forming an artificial surface layer on the surface of the base material, which is different from the mechanical, physical and chemical properties of the base material.
Train a group of mechanical engineers who can truly understand the essence of design and combine theory with design.
We cannot control the Customer’s environment. We can only control the design and declare the design and hazards to the Customer, so they can determine the reasonable safety measures beyond our machine envelope.
Electroplating is the process of plating a thin layer of other metals or alloys on the surface of certain metals using the principle of electrolysis. It is the process of using electrolysis to attach a layer of metal film to the surface of metal or other materials to prevent metal oxidation ( Such as rust), improve wear resistance, electrical conductivity, reflectivity, corrosion resistance (copper sulfate, etc.) and enhance aesthetics.
The most commonly used medium carbon quenched and tempered steel, with good comprehensive mechanical properties, low hardenability, and easy to crack during water quenching.
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.
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.
