To be honest, the first time I heard the word "packing" in this small edition, I didn't know what it was. After online inquiry and relevant information search, I learned that packing is also known as "braided packing". It is a kind of sealing packing made of expanded graphite wire. Next, this small edition will introduce in detail what is packing and how it works? If you want to know, please join us to learn! Prepare packing Packing, also known as sealing packing, is usually woven from softer linear materials. Usually, strips with square or rectangular cross-sectional area and circular…

The purpose of sealing is to prevent the objects from being damaged, and to have the effect of shock proof, pressure reduction and sound insulation. According to the understanding of this small edition, there are many sealing methods, each of which is different. Today, this small edition will explain the difference between packing seal and mechanical seal and the comparison between them. If you want to know about children's shoes, hurry up and follow the pace of this small edition. Let's have a look! The packing seal is to compress the packing through the packing gland to make the packing…

As a representative of emerging industries, industrial robots can create new industries by developing new demands. It is the key to China's realization of "made in China 2025" and also a new engine to drive economic development after China's economy enters the new normal. In the latest national economic industry classification, which will be officially implemented on October 1, 2017, robot manufacturing is included in the national economic industry classification as an independent industry for the first time. According to the new classification, industrial robot manufacturing and special operation robot manufacturing are two sub industries. It can be said that…

Thin plate structural members generally refer to structural members made of steel plates (including stainless steel plate, galvanized plate and white iron sheet) with a thickness of no more than 4 mm. For example, the roller drill shed, cab and electric shovel cab produced by our factory belong to this category. The control and correction of welding deformation of thin plate structural parts need advanced technology. The following will discuss the control and correction of welding deformation of lower thin plate structural parts together with the quick screening and editing. 1、 Causes of welding deformation Arc welding is an uneven…

First, from digitalization of production process to intelligent factory In the process manufacturing fields of petrochemical, steel, metallurgy, building materials, textile, papermaking, medicine, food and so on, the internal driving force for enterprises to develop intelligent manufacturing lies in the controllable product quality. It focuses on starting from the digital construction of production and changing from product end control to full process control based on the demand of quality control. Therefore, its intelligent factory construction mode is: First, promote the digitization of the production process, build a dynamic transparent traceability system covering the whole process on the basis of the…

Wood products processing refers to the processing process of changing the shape, size and surface quality of wood by destroying the connection between wood fibers through cutters. The machinery for processing wood products is called woodworking machinery. Woodworking machinery is widely used in construction, furniture, factory wood mold processing and home decoration industries. There are many kinds of woodworking machines, which can be divided into woodworking sawing machine, planer, milling machine, drilling machine, lathe and sanding machine according to their working principle, scope of application and performance structure. Woodworking machinery and equipment belong to equipment with high operational risk. Since…

With the higher and higher requirements of hardness in modern engineering material processing, the hardness of tools is also higher and higher, and more superhard tools are applied. Superhard tools are mainly used for cutting hardened steel, including carbon tool steel, alloy tool steel, high-speed steel, bearing steel, die steel, etc., or cutting various iron-based, nickel based, cobalt based and other thermal spraying (welding) parts. However, cutting different materials will have different superhard tools, so it is very important to understand the classification of superhard tools. Here is a brief introduction for you. (1) PCD metal cutting tool Tool type:…

one Scorched 1. Scorching phenomenon (1) The temperature is too high, or the instrument controlling the temperature is out of order, causing the plastic to scorch due to high temperature. (2) The rubber outlet of the machine head has large smoke, strong irritating smell and crackling sound. (3) Granular scorched matter appears on the plastic surface. (4) There are continuous air holes at the glue joint. 2. Causes of scorching (1) Super high temperature control causes scorching of plastics. (2) The screw has been used for a long time without cleaning, and burnt materials are accumulated and extruded with plastic.…

If no measures are taken after the door cover is welded, assembled and adjusted to be qualified, the flatness and clearance of the door cover will be greatly changed under the influence of external force and internal stress release during transportation and coating. This phenomenon is common in the automobile industry, especially the impact on flatness is obvious. In view of this problem, this paper introduces the concept of welding boss applied to the welding spot of the door cover, and proposes a new process method - using the welding boss to realize welding, so as to improve the rigidity…

With the development of microelectronics and computer technology, the development of numerical control technology in China has been promoted. The domestic numerical control system has been successfully developed, which ensures the quality and performance of numerical control machine tools in China. Numerical control machine tools have been widely used in various fields because of their strong adaptability to workpiece modification, high machining accuracy and high productivity. Numerical control technology has been widely used in sheet metal machine tools. It solves the problems of high precision, complex shape and large batch in sheet metal processing. Numerical control sheet metal machine tools…
