Metal cutting equipment Metal cutting CNC equipment is the most common numerical control equipment, and is also the most important sign of the development of numerical control technology. CNC machines with almost all kinds of metal cutting methods are used in the manufacture of high voltage switches. CNC lathes, CNC milling machines, CNC drilling machines, CNC boring machines, turning centers, machining centers, and turning and milling composite machining centers are all used in the manufacture of high-voltage switches. MetalWorking37 is on a regular lathe. Most of the high-voltage switch products use horizontal lathes, which are suitable for contacts, contact holders, machined shields, conductors, shafts, flanges, sleeves, etc. Due to the special requirements of electric fields for high-voltage switch products, many Parts have a continuous transition of arcs and arcs and straight lines, which must be machined on a CNC lathe. In addition, some parts such as axle pins, which require high precision and many varieties and small batches, are also commonly processed by numerical control equipment. The turning diameter of CNC lathe is generally between φ200～φ600mm, the processing length is below 1000mm, the spindle speed is 2000～5000rpm, and the tool position is 4～12. The general enterprise is equipped with economical and full-function equipment, and the economical type is used. Parts with lower precision and complexity are required, while those requiring higher use are fully functional. Vertical CNC machine tools (turning centers) are generally used less and can be used for large flanges, plate parts and small tanks. The CNC milling machine is mainly vertical, suitable for all kinds of connecting plates, joints, arm, hexagonal shaft, connecting seat, contact seat, etc. The working table is generally below 400mm × 1200mm, and currently mainly based on full-function type. Only some companies with long-term use of CNC equipment retain the early economical CNC milling machines. CNC boring machine is mainly used for processing various housings for GIS (gas insulated metal-enclosed switchgear) and individual large flanges. The worktable is above 1600×1400mm, and the X, Y and Z strokes are 1800mm, 1600mm, 2000mm. There are B-axis and rotary disc (U-axis), B-axis has 4×90 accurate positioning, flat disc stroke is 200mm, and the diameter of the boring shaft is 130mm. According to the size of the workpiece, it is also necessary to configure a CNC boring machine with a shaft diameter of 110mm, stroke, etc. Other parameters are reduced accordingly. At present, the products used by Zhongjie and Kunji are more. CNC drilling machine is used for various flanges, discs, seats and other parts. The use of CNC drilling machines for various hole types and thread processing can eliminate the scribing steps and improve the consistency of product processing and production efficiency. There are many kinds of such parts, the specifications are wide, and the processing methods are also many. Generally, the worktable is 400mm×600mm and 1000mm×1200mm. The machining center is a CNC milling and boring machine with automatic tool changer. It is superior to CNC milling and boring machine in terms of function, precision, rigidity, efficiency and protection. It is generally divided into vertical and horizontal types. The vertical machining center is mainly It is used for processing various connecting plates, joints, arm, hexagonal shaft, connecting seat and contact seat. The horizontal machining center is mainly used for processing mechanism bracket and GIS housing processing. Vertical machining center workbench generally selects 400mm×600mm to 600mm×1000mm, Z-axis stroke is more than 500mm, and the tool magazine capacity is more than 20. According to the needs of machining shaft parts, a certain number of CNC rotary table (fourth axis) need to be configured. The center height of the rotary table is 150mm~200mm. The horizontal working table can be selected from 500mm×500mm, 1000mm×1000mm and 2000mm×2000mm for processing of mechanism, Cylinder and GIS shell. The X, Y, and Z strokes can be determined according to the size of the product, but the maximum range should be greater than 3000mm, 1800mm, 2000mm, the diameter of the boring shaft is 130mm, the B axis has at least 4×90 accurate positioning, and the large horizontal machining center needs to be equipped with a flat disk. (Depending on the processing requirements of the sealing surface, it may not be matched), the flat disc stroke is 200mm, and the magazine capacity is 20 to 40. Turning centers and turning-milling composite centers are generally used less frequently, but with the continuous improvement of product requirements, especially the introduction of some foreign technologies, such equipment is gradually being used. Compared with the CNC lathe, the turning center has added the C-axis and the power tool rotation axis, and has the milling, tapping and drilling functions of the workpiece end face. The turning-milling compound center adds the Y-axis, C-axis and B-axis to the turning center. And the tool magazine, and some even have a second spindle, with the function of CNC lathe and micro pentahedron machining center, can complete the processing of most workpieces in one manual clamping. Cutting and welding equipment cutting CNC equipment mainly includes flame, plasma, laser cutting machine, welding equipment including steel and aluminum housing longitudinal seam and circumferential seam welding. The cutting machine is used for cutting steel and aluminum. The working area is generally 4m×6m, the flame cutting thickness is more than 80mm, the thickness of plasma cutting is generally 30mm, and it has the functions of sleeve cutting and automatic programming. The shell is stretched before stretching. The wire cutting can be performed by a special CNC cutting machine to complete the drawing of the outer hole of the outer cylindrical surface of the casing. Generally, a special numerical control cutting machine with four coordinates or more is required. The CNC laser cutting machine has the characteristics of high cutting speed and high precision. It is suitable for the cutting of thin plate materials with high precision requirements and the number of holes, slots, and many contours. It is mainly used in the opening and complex shape of the switch cabinet. The sheet of the part is blanked. After laser cutting, most of the subsequent contour processing can be omitted, and the carbon steel cutting thickness can reach 12mm or more (the aluminum plate stainless steel plate can be cut to a thickness of 6-8mm). There are many welding equipments, and there are longitudinal seams and ring seam welders of the same type of CNC. They are generally customized machines, including welders and welding fixtures. Welding is generally performed by DC and variable polarity plasma welders. The control of the action or the welding action and the welding current are controlled in whole or in part by numerical control technology. CNC equipment configuration features in the high-voltage switch industry, different types and sizes of enterprises, the configuration of CNC equipment has different characteristics. Generally, small enterprises are less equipped with numerical control equipment, and large-scale CNC equipment with stamping type. On the basis of this, large-scale well-known enterprises generally have imported flexible sheet metal production lines, mechanical processing and electric machining numerical control equipment. CNC equipment configuration principle CNC equipment has the advantages of high precision, good quality and fast speed. It has been widely used in high-voltage switch manufacturing, and is also an essential means for enterprise development and new manufacturing technology, but CNC equipment also has high investment and consumption. High and demanding features. For the configuration and investment of numerical control equipment, the following aspects must be analyzed and researched: (1) The configuration of imported or domestic CNC equipment must be based on the principle of maximizing the ultimate benefit (lowest cost), especially in the decision to use imported equipment. Or on domestic equipment. (2) The unit manufacturing cost of the product is closely related to the fixed manufacturing cost, output, and unit variable manufacturing cost. It is best to use mathematical means to obtain the quantitative relationship.
