Description

Technical Field

[0001] This utility model relates to the field of column technology, specifically a column with a double-layer irregular structure. Background Technology

[0002] Electrical discharge machining (EDM) machines, which use the principle of electric spark discharge to process metal parts, operate on a principle quite different from ordinary metal cutting machine tools. They are equipped with a high-energy pulse power supply that provides the necessary energy to generate the electric spark, causing a high-intensity electrical pulse between the tool electrode and the workpiece electrode, thus initiating the discharge spark. During the machining process, the tool and workpiece do not have direct contact, therefore no strong cutting force is required, which also eliminates the need for a main drive system. However, to ensure a small discharge gap between the electrodes, the machine tool is equipped with a highly sensitive automatic gap adjustment device that can automatically measure and adjust the gap in real time.

[0003] The machine tool mainly consists of a bed, column, saddle, ram, spindle head, and worktable. Its components must possess sufficient rigidity to ensure that deformation during machining does not affect the discharge gap, thus ensuring smooth machining. In electrical discharge machining (EDM), both the tool electrode and the workpiece are immersed in the working fluid. The function of the working fluid is to compress the spark channel during discharge, concentrate the current, and rapidly eliminate ionization and restore the insulating state after discharge to prevent arcing. Simultaneously, the working fluid also cools the tool and workpiece, ensuring stable machining. Furthermore, the machine tool is equipped with a working fluid circulation system, which forces the working fluid to circulate and promptly remove electro-erosion products from the electrode gap.

[0004] As the fundamental structure of a machine tool, the stability of the column is crucial to the relative positions of the electrode, worktable, and workpiece. The precision of these components directly determines the machining quality. To ensure high precision, the column not only needs a reasonable structure and high rigidity to withstand the spindle load and the inertial forces of moving parts, but also must be able to resist deformation caused by temperature changes. Furthermore, aging treatment to eliminate internal stress is essential to ensure long-term stability. Therefore, there is an urgent need for a double-layered, irregularly shaped column to solve these technical problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution:

A first hoisting hole and a second hoisting hole are respectively opened on the left and right sides of the front end of the column body. Bolt holes are opened at the front end of the bottom of the column body. A cross-shaped reinforcing rib is installed on the inner side of the side extensions.

[0008] Preferably, the column adopts a wide-body, box-type casting structure, and has a reasonable arrangement of cross-shaped reinforcing ribs inside to enhance rigidity and strength and reduce deformation.

[0009] Preferably, the main body of the column adopts a V-shaped and planar linear guide.

[0010] Preferably, the main body of the column is made of gray iron HT200 resin sand casting, and undergoes two aging treatments to eliminate internal stress and reduce deformation.

[0021] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings. In the embodiments of the present utility model, the different types of cross-sectional lines are not labeled according to national standards, nor do they specify material requirements for the components; they are used to distinguish the cross-sectional views of the components in the drawings.

[0022] Please see Figure 1-6 A double-layer irregularly shaped column includes a column body 12. The left and right sides of the column body 12 are respectively provided with side extensions 6 and end extensions 10. The upper ends of the column body 12 are provided with linear guides 5. The upper middle part of the column body 12 is provided with motor seats 1 on both sides. A first bearing seat 3 and a second bearing seat 4 are installed between the motor seats 1. Wiring holes 2 are opened on one side of the first bearing seat 3 and the second bearing seat 4. The front end of the column body 12 is provided with a first hoisting hole 8 and a second hoisting hole 9 on the left and right sides respectively. The bottom front end of the column body 12 is provided with bolt holes 11. The inner side of the side extensions 6 is provided with cross-shaped reinforcing ribs 7.

[0023] The column adopts a wide-body, box-type casting structure, and has a reasonable arrangement of cross-shaped reinforcing ribs 7 inside to enhance rigidity and strength and reduce deformation.

[0024] The column body 12 adopts a V-shaped and planar linear guide 5.

[0025] The column body 12 is made of gray iron HT200 resin sand casting and undergoes two aging treatments to eliminate internal stress and reduce deformation.

[0026] The upper part of one longitudinal side of the column body 12 also adopts an outward extension design, extending outward by about 150mm.

[0027] It should be noted that the column body 12 is made of high-quality, strong and tough cast iron, and through a scientifically designed reinforcing rib, it achieves high rigidity and minimal thermal deformation, thus enabling high-precision and high-speed machining performance. The design of the column body 12 also emphasizes reducing friction and thermal impact, employing V-shaped and flat guide rails covered with ultra-wear-resistant synthetic materials to reduce the coefficient of friction between the guide rails and improve the machine tool's motion accuracy.

[0028] The column adopts a wide-body, box-type casting structure, with internally arranged cross-shaped reinforcing ribs to enhance rigidity and strength and reduce deformation. This design can withstand the load of the spindle and the inertial force of sudden acceleration of moving parts, while reducing deformation caused by temperature changes.

[0029] The column material is made of gray iron HT200 resin sand casting, which undergoes two aging treatments to eliminate internal stress, reduce deformation, and maintain good stability and dimensional accuracy. Firstly, gray iron HT200 possesses excellent mechanical properties. It has high compressive and bending strength, making it suitable for withstanding large mechanical loads and wear. Its tensile strength is 200 MPa, and its hardness is approximately 180 HB. These properties enable gray iron HT200 to meet the requirements of EDM columns under high-speed movement and high-load operating conditions. Secondly, resin sand casting offers good machinability and cost-effectiveness. It can produce parts with complex shapes to meet the needs of different machine tools. Furthermore, the mold cost of resin sand casting is low, making it suitable for mass production and significantly reducing production costs. Finally, both gray iron HT200 and resin sand casting exhibit excellent wear resistance and vibration damping performance. Gray iron HT200 has good wear resistance and vibration damping properties, effectively absorbing and reducing vibration, improving the machining accuracy and service life of the machine tool. This is very important for EDM column, because the column is subjected to frequent impacts and vibrations during operation. Good wear resistance and shock absorption performance can extend its service life and ensure machining precision.

[0030] The inner side of the main body of the column 12 is provided with cross-shaped reinforcing ribs 7 to enhance the tensile strength.

[0031] Both ends of the column adopt an outward extension design, which expands the travel of the upper main shaft on the linear guide 5 and achieves full coverage of the workbench area.

[0032] The upper part of the longitudinal side of the column also adopts an outward extension design, extending outward by approximately 150mm. This increases the distance between the two side rails while maintaining the original base size, thus distributing the stress and making the operation safer and more stable. The side is equipped with a first hoisting hole 8 and a second hoisting hole 9, and the bottom is equipped with bolt holes 11. It adopts a fully enclosed ribbed design, which has a large span and high rigidity. The comprehensive application of transverse ribs, longitudinal ribs, diagonal ribs, and circular ribs at the joints enhances the overall load-bearing strength.
