Also be provided with cushion block, cushion block is arranged on the top of cover plate, and the endoporus tight fit of the little cylindrical of cushion block and described cover plate.The outside wall surface of described die holder is taper seat, and the tapering of the outer wall taper seat of die holder equates with the tapering of the circular conical surface of inner wall of drift, and the internal face bottom equal diameters of the outside wall surface bottom diameter of die holder and drift.Described slide block has 3 ~ 6.
That the present invention has is simple in structure, production cost is low and the advantage such as operating efficiency height.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with specific embodiment, the invention will be further described.
The die device of this punching press internal spline, upper surface at base plate 9 is fixed with die holder 8, at the middle part of die holder 8, plug 2 is installed, have the spline be complementary with workpiece on plug 2, upper surface at die holder 8 offers chute, the length direction of chute is arranged along the radial direction of die holder 8, bottom land at chute offers mounting groove 10, be provided with spring 7 in mounting groove 10, be provided with cover plate 4 above die holder 8, cover plate 4 fixedly mounts by securing member with die holder 8, be provided with the slide block 5 more than two or two between die holder 8 and cover plate 4, the outside wall surface of slide block 5 is taper seat, there is protruding internal spline and rush bar 11 on the internal face of slide block 5, internal spline rushes bar 11 and coordinates with the spline of offering on plug 2, lower surface at slide block 5 is fixed with sliding pin 6, the lower end of sliding pin 6 embeds in described chute 10, the outer end of spring 7 and sliding pin 6 offset, be provided with drift 1 above slide block 5, described drift 1 is hood-shaped body, the internal face of drift 1 is taper seat, and the tapering of the circular conical surface of inner wall of drift 1 equates with the tapering of the outer wall taper seat of slide block 5.
Also be provided with cushion block 3, cushion block 3 is arranged on the top of cover plate 4, and the endoporus tight fit of the little cylindrical of cushion block 3 and described cover plate 4.
The outside wall surface of described die holder 8 is taper seat, and the tapering of the outer wall taper seat of die holder 8 equates with the tapering of the circular conical surface of inner wall of drift 1, and the internal face bottom equal diameters of the outside wall surface bottom diameter of die holder 8 and drift 1.
Described slide block 5 has 3 ~ 6.
Drift 1 is fixedly connected with slider of punch.Plug 2 is placed on center, the interior step axial location of the large cylindrical lower surface of plug 2 and die holder 8, and the little cylindrical in the lower end of plug 2 and die holder 8 endoporus matched in clearance also are slidably connected with spline.Cushion block 3 is placed in above 4 cover plates, the little cylindrical of cushion block 3 and the endoporus tight fit of cover plate 4.Cover plate 4 is placed in the following of cushion block 3 with above 8 die holders, and fixing with screw and die holder 8.Slide block 5 is placed in the chute of die holder 8, and the lower surface of slide block 5 is embedded with pin 6 ，Ke Xiang centers and moves.Pin 6 be placed in slide block 5 below and with slide block 5 below aperture tight fits, expose supported underneath spring 7.Spring 7 is placed in the mounting groove 10 of die holder 8, and an end supports mounting groove 10 inwalls, and the other end is supported on pin 6 planes.Die holder 8 is placed in the below of cover plate 4 and the top of base plate 9.Base plate 9 is placed in the below of die holder 8 and fixes with screw and die holder 8.
