The utility model is further set to: described supporting component comprises support member, dwang, described upper bolster one side is provided with the holddown groove caving inward, described dwang runs through support member and its two ends are fixed on the cell wall of holddown groove, described support member one end is rotatably connected with dwang, and the lateral wall of the other end and punch is inconsistent.
By adopting technique scheme, described support member is fixed on by dwang in the holddown groove of upper bolster, and described support member is rotatably connected with dwang, simple in structure, is convenient to install.
The utility model is further set to: the inconsistent one end of described support member and punch is provided with the arcwall face suitable with the lateral wall of punch.
By adopting technique scheme, improve support member and punch conflict area, make support member better support punch, prevent the stressed flexural deformation of punch.
The utility model is further set to: described arcwall face is provided with chamfering on one side towards fixed part.
By adopting technique scheme, described support member relatively and patrix do to inner rotary smaller angle, just can make support member separate with punch, be convenient to processing work and take out from punch, increase work efficiency.
The utility model is further set to: described die shoe is provided with two for locating the keeper of processing work, and described left die and right die are placed between two keepers.
By adopting technique scheme, processing work can quick and precisely be located, increase work efficiency.
