Abstract
The invention discloses a high-speed punch which comprises a machine station. Four guide pillars are arranged on the middle part of the machine station. The guide pillar is provided with a slider through a sliding mechanism. The slider can slide up and down along the guide pillar. A driving mechanism for driving the slider to move up and down is arranged on the upper part of the machine station. A lubricating system which is connected with an oil pump system is arranged in the driving mechanism and the sliding mechanism. The machine station is an integrated structure which is made of ductile iron. An integrated thermal balance structure which is communicated with the lubricating system is arranged on the middle lower part of the machine station. The assembly precision of the invention is higher than a fission structure and can be maintained easily. And the machine body can not deform easily. Therefore, higher processing precision can be achieved. At the same time, the whole temperature risings of the machine station are basically identical. The problem that the machine heats to deform the machine body to lower the processing precision during the high-speed processing is solved. And with the totally enclosed lubricating system adopted, the possibility of foreign bodies for entering the inside of the machine is avoided, and the service life and the reliability of the machine are greatly improved.
