Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.
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, on plug 2, have the spline matching with workpiece, 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, in mounting groove 10, be provided with spring 7, above die holder 8, be provided with cover plate 4, cover plate 4 fixedly mounts by securing member with die holder 8, between die holder 8 and cover plate 4, be provided with more than two or two slide blocks 5, the outside wall surface of slide block 5 is taper seat, on the internal face of slide block 5, there is protruding internal spline and rush bar 11, 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, above slide block 5, be provided with drift 1, 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 little cylindrical of cushion block 3 and the endoporus tight fit of 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 lower end of plug 2 and die holder 8 endoporus matched in clearance are also 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 be placed in cushion block 3 below with above 8 die holders, and fix 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 mounting groove 10 inwalls are supported in one end, and the other end is supported in 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.
