The invention provides a compound crimping die and terminal machine. The compound crimping die comprises a bottom plate, wherein a support is glidingly connected on the bottom plate, and a sliding drive for driving the support to slide on the bottom plate is fixed on the support, a plurality of die bodies corresponding to a plurality of terminals are arranged horizontally and in parallel on the support, each die is glidingly connected with a pressure head of the terminal machine in the horizontal direction through a sliding block, and each sliding block is glidingly connected with the support in the vertical direction. By adopting the compound crimping die disclosed by the invention, a plurality of the terminals can be crimped when the terminal machine does not replace the dies to improve the utilization rate of the terminal machine and save the cost.
