Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

The utility model provides a die holder stop device for punch press, which comprises a frame, still include 4 spacing subassemblies, spacing subassembly includes fixed subassembly and slip subassembly, fixed subassembly includes fixing base 2, a frame body is provided with 4 stands 3, and stand 3 is the cuboid type, 4 stands 3 are square distribution at the lower terminal surface of frame, fixing base 2 is fixed mutually with stand 3 and is located the inboard of the frame of stand 3, the slip subassembly sets up at fixed subassembly, between upper die base 4, fixed subassembly and slip subassembly sliding fit are used for restricting the square space that 4 vertical activities of upper die base enclose at 4 stands 3.
