The purpose of this utility model is achieved through the following technical solutions：
A kind of stretching cutting dies, including upper die holder and lower die holder, the upper die holder bottom surface are equipped with upper mold core, upper mold core
Middle part processing is fluted, and groove side is equipped with knife tool, and lower mold core is equipped in the middle part of the lower die holder, be equipped in the middle part of lower mold core with
The punch that groove top profile matches is additionally provided with holding pad in lower mold core, is machined with and drift profile kissing in the middle part of holding pad
The through-hole of conjunction, the holding pad top surface be equipped with positioning plate and buffer, the positioning plate in a ring, the holding pad of positioning plate side
It is equipped with limited block, the buffer is mounted on the quadrangle of holding pad, and the side wall of holding pad is equipped with lubricating substance slot, the lubricating substance slot
Corresponding with knife tool, the bottom surface of holding pad is equipped with stop screw, and the bottom of the stop screw is mounted in lower mold core.
Multiple locating pieces are machined on the side wall of the punch.
The locating slot to match with locating piece is machined in through-hole on the holding pad.
Notch corresponding with knife tool is machined on the positioning plate.
The utility model has the following effects that：
(1) by the way that pressure coil is arranged, so that workpiece is quickly positioned and is processed, improve the processing efficiency of workpiece；
(2) by the way that lubricating substance slot is arranged, so that waste material is rapidly separated mold, waste material is avoided to influence punch process.

Specific implementation mode
Embodiment
As shown in Figure 1 to 4, stretching cutting dies provided in this embodiment include upper die holder 1 and lower die holder 2, it is described on
1 bottom surface of die holder is equipped with upper mold core 11, and 11 middle part processing fluted 12 of upper mold core, 12 side of groove is equipped with knife tool 13, institute
It states 2 middle part of lower die holder and is equipped with lower mold core 21,21 middle part of lower mold core is equipped with the punch 22 to match with 12 top profile of groove, punch
It is machined with multiple locating pieces 23 on 22 side wall, holding pad 3 is additionally provided in lower mold core 21,3 middle part of holding pad is machined with and punch
The through-hole 31 that 22 profiles match is machined with the locating slot 32 to match with locating piece 23 in the through-hole 31 on holding pad 3, described
3 top surface of holding pad is equipped with positioning plate 33 and buffer, and the positioning plate 33 in a ring, is machined with and knife tool on positioning plate 33
The holding pad 3 of 13 corresponding notch 34,33 side of positioning plate is equipped with limited block 36, and the buffer is mounted on holding pad 3
The side wall of quadrangle, holding pad 3 is equipped with lubricating substance slot 37, and the lubricating substance slot 37 is corresponding with knife tool 13, the bottom surface of holding pad 3
It is equipped with stop screw 38, the bottom of the stop screw 38 is mounted in lower mold core 21.
The application method of the utility model：
Workpiece is placed on holding pad 3 first, then controls 1 downlink of upper die holder, the upper mold core 11 on upper die holder 1 is under
Lower mold core 21 on die holder 2 stretches workpiece, while the knife tool 13 on upper die holder 1 cuts the corner of workpiece
It cuts, 1 uplink of last upper die holder simultaneously takes out workpiece.When 1 downlink of upper die holder, the buffer on holding pad 3 can slow down upper die holder 1
Impact force extends the service life of mold.
