Closed single-point high-precision punching machine has extremely high accuracy requirements in industrial production, and its accuracy retention is crucial.
First of all, the body structure design of the punching machine is the basis for affecting the accuracy retention. The high-strength cast iron or steel structure is adopted, and after careful mechanical analysis and optimization, it is ensured that the body does not deform when it is subjected to the punching load for a long time. Reasonable structural layout and the setting of reinforcing ribs can effectively disperse stress, reduce the distortion and vibration of the body, and thus provide guarantee for the stability of accuracy.
High-precision parts processing and assembly process are also key. Key components such as sliders, guide rails, crankshafts, etc. use advanced processing equipment and processes to strictly control processing accuracy and surface quality. During the assembly process, through precise measurement and adjustment, ensure that the matching accuracy between the components meets the design requirements and reduce the accuracy loss caused by assembly errors.
In order to reduce the long-term drift of accuracy, high-quality material selection is indispensable. Wear-resistant, heat-resistant and deformation-resistant materials are used to manufacture key components, such as high-strength alloy steel for crankshafts, to withstand long-term reciprocating motion and impact. At the same time, surface treatment of easily worn parts, such as quenching and nitriding, is performed to improve their hardness and wear resistance.
A good lubrication and cooling system also plays an important role in maintaining accuracy. Effective lubrication can reduce friction and wear between components and reduce heat generation, thereby avoiding changes in accuracy caused by thermal deformation. The cooling system can take away heat in time and maintain the punch press working within a suitable temperature range.
Regular accuracy testing and maintenance are essential. Use high-precision measuring instruments to regularly test the various accuracy indicators of the punch press, such as slider stroke accuracy, parallelism, verticality, etc. Once an accuracy deviation is found, adjust and repair it in time. At the same time, formulate a scientific and reasonable maintenance plan, including cleaning, tightening, and replacing wearing parts, to ensure that the punch press is always in good working condition.
In addition, the correct use and standardized operation of the operator can also maintain the accuracy of the punch press to a certain extent. Train operators to be familiar with the performance and operation essentials of the punching machine to avoid damage to the punching machine and loss of precision due to incorrect operation.
In summary, through a series of measures such as optimizing the machine body structure, improving the processing and assembly precision of parts, selecting high-quality materials, improving the lubrication and cooling system, regular inspection and maintenance, and standardized operation, the closed single-point high-precision punching machine can effectively maintain accuracy, reduce long-term drift, and provide reliable guarantee for high-quality stamping production.
