Tube cutoff die set |
摘要 |
A method and apparatus for severing successive lengths of tubing in a die set in which the movement of an upper die shoe is translated by mechanism to clamp the tubing on a lower die shoe, move a notching blade across the clamped tubing to slot the tubing, and pass a cutoff blade through the slot to sever the tubing. Use of a lever arm pivoted to one of the die shoes in combination with a cam on the other die shoe optimizes horizontal movement of the notching blade relative to vertical movement of the die shoes. In a preferred form, the cutoff blade is passed through a slot in the notching blade holder. The die set can be used in apparatus where the tubing is intermittently supplied, or, as in a tubing mill, a continuous length of tubing is moved during the severing process.
