我厂先后生产过多种规格的对击锤。为了向设计、生产和使用单位提供对击锤的各种性能参数,在出厂前都要进行大量的测试工作。由于对击锤的打击能量是其锻造能力的重要标志,因此,对击锤功能的测定就成为主要的测试内容之一。通常采用的打击能量测试方法可以归结为两种:一种是以示功图为基础,采用示功仪和P(压力)—S(行程)曲线法测理论打击能量,另一种是用示波器对检测锤头速度的光电速度传感器发出的脉冲到示波照象,然后由人在标定的时间间隔内数脉冲个数,并找到最大脉冲数从而求出实际最大平均打击速度及能量。但是,这些方法,都存在测试精度不高、数据处理方法繁琐的缺点,而且测出的实际打击速度 I plant has produced a variety of specifications on the hammer. In order to design, production and use of the hammer units to provide a variety of performance parameters, a lot of testing before leaving the factory. Since striking energy is an important indicator of its forging ability, the determination of hammer function has become one of the main test contents. The commonly used methods of striking energy test can be summed up in two ways: one is based on the dynamometer, the use of dynamometer and P (pressure) -S (stroke) curve method to measure the theory of striking energy, and the other is to use oscilloscope On the photoelectric speed sensor to detect the speed of the hammer sent to the oscillographic image, and then by the number of pulses in the calibration interval and find the maximum number of pulses to find the actual maximum average strike speed and energy. However, these methods have the shortcomings of low test accuracy and complicated data processing methods, and the actual attack speed
