The DC electric welding machine is a kind of electric welding machine that uses the high voltage arc generated when the positive and negative poles are short circuited instantaneously to melt the solder on the welding electrode, so that they can achieve the purpose of atomic combination. Now, let's get to know it together with the Speed Plus Mesh! Principle of DC welding machine: DC electric welding machine is an electric welding machine whose output power is DC power. It has the advantages of easy arc ignition, stable arc and good welding quality. DC electric welding machine can also be…

In order to reduce the vibration and noise of the hydraulic system of CNC machine tools and avoid the expansion of noise, prevention and improvement should be done in the following aspects: （1） Improvement of Hydraulic System Structure In the process of controlling the hydraulic system of CNC machine tools, attention should be paid to the use of low-noise hydraulic components. Through research, it is found that the old hydraulic pumps are mainly plunger pumps or gear pumps, and their noise vibration and noise are much higher than those of vane pumps, and their rated pressure is also very high.…

1. The universality and harmfulness of burrs Burr is an inevitable product of metal processing, which is difficult to avoid completely. The existence of burr not only affects the appearance of the product, but also affects the assembly and service performance of the product, speeds up the wear between equipment and reduces the service life. With the development of high technology and the improvement of product performance, the requirements for product quality become more and more strict, and deburring of mechanical parts becomes more and more important. The existence of burr has a great impact on product quality, product assembly,…

Machining performance is not only related to the interests of enterprises, but also related to safety. While bringing economic benefits to enterprises, it can also effectively reduce the probability of safety accidents. Therefore, it is particularly important to avoid part deformation in the process of part processing. Operators need to consider various factors and take corresponding measures to prevent deformation during processing, so that finished parts can be used normally. In order to achieve this goal, it is necessary to analyze the causes of deformation in part processing and find out reliable measures for part deformation, so as to lay…

It refers to a metal thermal processing process in which materials are heated, insulated and cooled in solid state to obtain expected structures and properties. This technology plays an extremely important role in the flat plate platform industry. In order to make metal workpieces have the required mechanical, physical and chemical properties, in addition to reasonable selection of materials and various forming processes, heat treatment process is often essential. First, the quick screening editor introduces: 1、 Surface treatment technology of mould In addition to the reasonable matching of the matrix with high strength and toughness, the surface performance of the…

Seam welding machine refers to the resistance welding machine in which the weldment is assembled into a lap joint or butt joint and placed between two roller electrodes. The roller electrode pressurizes the weldment and rotates. Continuous or intermittent pulse power is transmitted to form a continuous weld. It is widely used in the thin plate welding of oil drums, cans, radiators, aircraft and automobile fuel tanks, and sealing containers in jet engines, rockets and missiles. Working principle of seam welder: 1. The basic type of seam welding of the seam welding machine is based on the mechano electrical coordination…

Forging is a combination of forging and stamping. It is a forming processing method that uses hammers, anvils, punches or dies of forging machinery to exert pressure on the blank to produce plastic deformation, so as to obtain the required shape and size. In the forging process, the billet has obvious plastic deformation and a large amount of plastic flow; In the stamping process, the blank is formed mainly by changing the spatial position of the area of each part, and there is no plastic flow within the blank with a large distance. Forging is mainly used to process metal…

Introduction to industrial switch: Industrial switches and commercial switches are positioned differently, so industrial switches pay more attention to stability, high temperature resistance, vibration resistance, corrosion resistance and other industrial characteristics. In the past few years, industrial switch manufacturers have mainly overcome several problems. How to make their products operate stably under different working conditions is their thinking. However, for the management of switches, everyone adopts the management mode of commercial switches. The management mode of the console is combined with the wizard mode of IE browsing and the network management software. The following describes the three management methods 1.…

Two professors at the University of Colorado in the United States invented an epoch-making cooling material made of TPX plastic. Its biggest feature is that it can cool objects without refrigerant and electricity! This film is made of a plastic called TPX. It looks like a plastic wrap, but under a microscope you will find many glass beads with a diameter of only 8 microns inside. The exterior is covered with transparent plastic. Ordinary plastics and ordinary glass beads can be combined to reflect sunlight back and prevent heat from penetrating downward. Its cooling principle is "radiation cooling". The received…

As a standard fastener, eyebolt is widely used in mechanical and electrical products. Its main function is to lift loads. As shown in the figure, it should be very common in our life. However, attention should be paid to the specifications of eyebolts in the process of selection. Any error is likely to affect or cause losses to the project. The following is a brief introduction to the specifications of eyebolts and the matters needing attention in the selection. GB825-88 specifies the structural type, size, technical requirements, lifting weight and service conditions of eyebolts. Technically, the eyebolts shall be made…
