    Development trends of punch presses

    In an increasingly pessimistic economic environment, cutting-free forming is a powerful way for companies to distance themselves from their opponents and win in the competition. Environmental protection is the theme of the 21st century. As an environmentally friendly processing method, it will be the key development direction. Forming of high-precision, high-value-added shapes is indispensable in non-cutting forming. In order to meet these requirements, it is necessary to master the comprehensive technology of the entire process from raw materials to finished products. The punch press is one of the key technical factors. This article will introduce in detail the basic characteristics of mechanical punch presses and the development direction of high-precision intelligent punch presses that have been developed in recent years and are suitable for various forming technologies.

    Basic characteristics of punch press

    The relationship between the characteristics of mechanical punch presses and product accuracy. There are two main characteristics of the punch press. One is rigidity, which includes vertical rigidity—the arch of the slider and workbench and the ductile extension of the sound card frame; and horizontal rigidity—the horizontal movement of the eccentric load impact reducing block. The second is the movement characteristics of the slider, including verticality, parallelism, straightness, etc., which have a great impact on the accuracy of the product. The accuracy of the product is not only related to the punch machine, but also related to the raw materials, molds, lubrication, etc. You cannot only consider one factor. Considering the factors of the punching machine, the accuracy of the thickness direction of the product is related to the vertical rigidity, while the error, bending or parallelism is related to the lateral rigidity and motion curve characteristics. Therefore, by improving this characteristic, product accuracy can be improved, mold service life can be increased, and production stability can also be improved.

    Development trend of mechanical punch press

    High rigidity and high functionality of universal punch press: The C-shaped punch press originally used as a general-purpose machine also pursues perfect high precision and high functionality, thus developing an all-in-one gantry type punch press; the speed around the bottom dead center is relatively slow and the SPM is not affected by Impact of the connecting rod punch. This connecting rod type punch press interposes two eccentric connecting rods between the driving gear and the crankshaft. When the driving gear rotates, due to the change of the connecting angle of the connecting rods, the crankshaft moves at an uneven speed. What makes this mechanical structure different from other mechanical structures is that there are fewer nodes in the force-receiving part and the overall gap is small.
