Status and development of mechanical speed press machine
The mechanical speed press machine is mainly used for high-speed stamping of precision parts, which requires high precision and rigidity. Regarding the definition of mechanical speed press machine, there is currently no unified standard. Its speed is related to many factors, mainly slider stroke, nominal force, stamping part size and punch structure, etc., so it is difficult to use a simple number as the dividing standard . The mechanical speed press machine mentioned in this article refers to a mechanical press used for stamping precision small parts.
The mechanical speed press machine adopts an integrated special cast iron alloy with high rigidity and shock resistance; the slider is designed with a long guide path and equipped with a slider balancing device to ensure precise and stable operation; all anti-wear components are automatically lubricated with electronic timing The system, if there is a lack of lubricating oil, the punch will stop automatically; the advanced and simple control system ensures the accuracy of the slide movement and stop; it can be matched with any automated production requirements to improve production efficiency and reduce costs.
The mechanical speed press machine is widely used in the stamping of small precision parts such as precision electronics, communications, computers, household appliances, auto parts, motor stators and rotors; it is suitable for mass production of precision electronics and hardware parts.
High speed and high precision are the development trend of mechanical speed press machine. In order to achieve high precision at high speed, foreign mechanical speed press machine manufacturers have conducted a lot of research in the fields of drive mechanism, bottom dead center control, etc., and have formed many patents. .
The continuous increase in the number of strokes of the mechanical speed press machine greatly improves the production efficiency and reduces the cost at the same time. Benefiting from the strong market demand for standardized, serialized, and batch-oriented functional stamping parts, the thickness of stamping parts is gradually reduced, and the required stamping tonnage is gradually reduced, which creates conditions for the mechanical speed press machine to increase the number of strokes. In addition, the development of high-speed precision stamping dies, especially multi-station high-precision progressive dies and automated peripheral equipment, has also created conditions for high-speed presses to increase the number of strokes. From the development history of mechanical speed press machine, as the number of strokes increases by leaps and bounds, its nominal force and stroke show a decreasing trend.
High precision refers to high static geometric accuracy and dynamic accuracy. The static geometric accuracy is related to the manufacturing level of the mechanical speed press machine, and the dynamic accuracy is achieved by adopting temperature control and bottom dead center dynamic compensation mechanism.
