High speed punch guide in the process of production should be how to choose

High speed punch guide according to the trajectory was divided into linear motion guide and circular motion guide rail, in accordance with the nature of work points motion guide rail, the feed movement guide and adjust the guide rail, in accordance with the stress distribution is divided into open type guide and closed guide. According to the friction properties are divided into sliding guide rail and rolling guide two kinds. According to the state of convex concave of bearing guide rail and can be divided into the concave convex shape of guide rail and guide rail; Convex triangle guide called yamagata guide, concave V rail triangle said. Convex guide rail is not easy to save oil, but easy to remove the chip of guide rail surface clutter. Concave guide is easy to store oil, also easy to fall into chip and sundry, must set protective device. Choose to use should grasp the following principles:

1, guide rail has larger rigidity and bearing capacity, with a rectangular guide rail, small and medium sized high speed punch guide and rectangular shape are adopted, while heavy high-speed punch press with double rectangular guideway.

2, for guidance of high precision punching machine adopts triangle, triangle rail face up bearing section and guiding role at the same time, can automatically compensate wear after clearance, the guidance precision is high.

3, rectangular and circular guide good manufacturability, fabrication, inspection is convenient. Triangle, dovetail guideway manufacturability is poor.

4, compact structure, small height and easy to adjust the high-speed punching machine, using dovetail guideway.
