Tagalog Improving the structural rigidity of punching machine tools can be achieved from the following aspects:
1. * * Optimized structural design * *: Reasonable structural design can effectively enhance the rigidity of punching machines. For example, adding horizontal and vertical support components to the main structure of a machine tool and increasing the lateral thickness of the bed can effectively improve the rigidity of the machine tool. In addition, selecting appropriate support methods, such as using steel ball screws for support, can avoid friction and wear caused by traditional sliding pairs, further improving rigidity.
2. * * Choose high-strength and high rigidity materials * *: The selection of materials is also the key to improving the rigidity of punching machines. Choosing materials with high strength and rigidity can increase the overall rigidity of the machine tool. The main components of the machine tool, such as the bed and workbench, should be made of high-quality cast iron or welded parts to ensure that the machine tool has sufficient rigidity.
3. * * Improve machining accuracy * *: In the process of machining machine tool components, machining accuracy should be ensured, machining errors should be controlled to ensure the interchangeability and assembly accuracy of components. In addition, during the machining process, attention should be paid to the coordination between the cutting tool and the workpiece, reducing the magnitude of cutting force to reduce the force on the machine tool and improve its rigidity.
4. * * Use shape memory alloy materials * *: In the structural design of punching machines, shape memory alloy materials can be considered. This material can effectively improve the structural stiffness under the action of aerodynamic heat, as the elastic modulus of shape memory alloy materials increases with temperature.
5. * * Active strain energy adjustment * *: The structure is heated and controlled by embedding a pre stretched shape memory alloy wire driver into the structure, and the stiffness of the structure is controlled by using active strain energy adjustment. This method can use shape memory alloy wire actuators to change the stress state inside the structure and achieve stiffness control.
In summary, by optimizing structural design, selecting high-strength and high rigidity materials, improving machining accuracy, using shape memory alloy materials, and adopting active strain energy adjustment, the structural rigidity of punching machine tools can be effectively improved.
