Due to the development of press machine tools in the direction of large multi-station, the thickness of the steel plate used for machine tool components is increased, and it is capable of cutting high-power steel plates of 300mm to 400mm and above with fast cutting speed and excellent cutting quality cutting torch and other accessories. Increase in demand. In recent years, the industrial development direction of replacing acetylene gas with C3 series gas is particularly obvious. Therefore, the demand of cutting production units for safe, efficient, environmentally friendly and energy-saving new gas has increased significantly.
Because most of the components such as press machine tools use steel plates with a thickness of about 30 to 40 mm, and when cutting in this thickness range, the new fine plasma arc cutting equipment is used by the unit because its cutting speed is about 5 times of the flame cutting speed. Greatly welcome.
As the press is developing in the direction of automatic loading and unloading, most of the automation equipment frames are welded by various profiles or pipe fittings. Therefore, professional cutting equipment such as special cutting equipment for pipe or pipe fittings and pipe bevel cutting equipment have great market demand. space.
The development of the machine tool manufacturing industry has increased the demand for welding equipment and welding materials due to the increase in the production of welding parts and the number of welding personnel. Due to the large differences in the skills of the practitioners, the welding quality requirements of the products are gradually increasing, so the fully automatic welding machines and digital welding machines that are relatively less dependent on the skill of the operators are popular. As energy consumption continues to be the biggest constraint to economic development, new energy-saving welding equipment such as CO2 welding machines are popular with users.
Due to the continuous development of high-speed, anti-pitting and high-life parts of the gears of the transmission components of the press, the materials of the welded gears are increasingly used with high-carbon equivalent alloy steel such as 42CrMo, and the welding of such alloy steels is required. The demand for medium and high-grade welding materials such as high tensile strength and low sulfur and low phosphorus welding wire, high tensile strength and low sulfur and low phosphorus welding wire is increasing.
Since most of the CNC machine tools pursue a human appearance, the appearance parts of CNC machine tools mostly use cold-rolled sheets as decorative parts. Most of these thin-plate decorative parts use spot welding to solve the connection problem. Therefore, spot welding equipment for thin plates is popular with machine tool manufacturing.
The development of the machine tool manufacturing industry analyzes the demand for welding in the field of welding. The level of durability of the machine tool has always been a key indicator to measure the pros and cons of the machine tool. The removal or homogenization level of the welding residual stress of the machine tool structural part has always been the most concerned issue for the machine tool user. . Compared with the cycle of the component's thermal aging, the energy consumed and the required hardware facilities, the vibration aging has its inherent technical advantages and application effects in many aspects, and is increasingly being welded. The production unit and the machine tool are recognized by the user. There is still much room for development in the production and sales of vibration aging equipment for weldments.
The components of the transmission parts of the press, the rocking shaft and other components are subjected to large dynamic loads during operation. If the residual stress of the weld is not well treated, and the work is subjected to a large dynamic load, the stress concentration will be large, causing fatigue fracture of the component or weld.
The development, production and effective use of stress-relieving equipment during and after welding are the problems that relevant scientific research institutions and professional production companies should focus on.
In the production of machine tool equipment, in order to improve the appearance quality of the machine tool, the steel plate bending structure or the steel plate rolling structure is often used externally. To produce such a structure, a steel plate bending machine or a steel plate bending machine is used. Such steel sheet forming equipment has a wide market demand space.
At present, the total production of each welding production unit is large, and the production work area is relatively small. The large amount of welding fumes generated in the welding production poses a great harm to the health of the welding practitioners. Especially in the winter in the north, there is a contradiction between maintaining room temperature and harmful smoke emissions. The environmental protection department is also constantly putting forward new requirements for welding fume treatment.
All of these, the development and production of new welding materials (such as non-copper welding wire), the control and treatment of welding fumes, the renewal and replacement of welding methods, the development and development of welding protection products, and the development and upgrade of welding equipment. All new topics and challenges have been raised.
