Fine regulating device for height of male die

The invention discloses a fine regulating device for the height of a male die. A U-shaped block is fixedly installed between an upper die base and a fixing plate. The upper die base is provided with a counter bore. The extending direction of a groove in the U-shaped block is perpendicular to the axis of the counter bore. A first bolt penetrates through the counter bore and the U-shaped groove in sequence, and the threaded end is placed in a via hole of the fixing plate. A rod part of the first bolt is sleeved with an elastic component, and the elastic component is placed in a big bore body of the counter bore. A sliding block is slidably assembled in the groove of the U-shaped block. A cushion plate is arranged at the open side of the U-shaped block and fixedly connected with the upper die base and the fixing plate. A second bolt penetrates through the cushion plate and the rear end of the sliding block and is in threaded connection with the sliding block. According to the fine regulating device for the height of the male die, the male die can be installed at the threaded end of the first bolt, and the height of the male die can be fine adjusted by fastening or loosening the second bolt; on the premise that the die is not detached, the height of the male die can be fine adjusted rapidly and conveniently, so that the time of die manufacturing and die regulating is shortened, the working efficiency is improved, and the manufacturing cost is reduced.
