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…

Working principle of automatic numerical control lathe Machining parts on automatic CNC lathe usually goes through the following steps: 1) According to the drawings and process plans of the processed parts, the program sheet shall be prepared with the specified code and program format and recorded on the carrier. 2) The program on the program carrier is input into the CNC unit through the input device. 3) After processing the input program, the CNC unit sends a signal to the servo system of each coordinate of the machine tool. 4) The servo system drives the moving parts of the machine…

1. Clean the grinder with a brush after daily operation. It is strictly forbidden to blow the worktable or guide rail directly with an air gun to prevent iron chips from entering the guide rail and affecting the precision of the grinder. 2. It is strictly prohibited to use a fan to blow against the workbench during operation, so as to prevent dust and iron filings from rolling back into the guide rail, which will affect the accuracy and feel of the guide rail. 3. The guide rail oil of the grinder should be replaced and added in time. Generally,…

With the gradual rise of people's demand, 3D printing enterprises are making their products bigger and bigger, just like the development of mobile phone screens. 3D printing is not a strange word, especially in manufacturing and medical biology. However, with the gradual development of 3D printing, the original technology of 3D printer has not been further improved, especially the development of FDM technology. It can be said that there is basically no technical breakthrough. However, some enterprises are keen on one thing: big, bigger! With the slogan of Apple, why is it big. Big, just fine? As we all know,…

First of all, I want to give you an idea: not all models can be used for 3D printing. The various online game character models look beautiful, but many of them can't be used. Why? Because the purpose of designer modeling is not to be used for 3D printing, many places do not design according to the requirements of 3D printing models. 2. Optimized design with less support The pain of adding support and removing support is only known through personal experience, and after removing support, it will still leave a very ugly mark on the model, and the process…
