Description
Technical field
The present invention relates to a kind of die device, specifically, is the single hole die set that a kind of retainer cover plate of large size bearing is used.
Background technology
Rolling bearing generally is comprised of inner ring, outer ring, rolling element and retainer four parts, and retainer can make rolling element be uniformly distributed, and prevents that rolling element from coming off, guiding rolling element rotation lubricate.
Because the retainer size of large size bearing is also relatively large, if punching die is designed to overall structure, the parts machining of the punch die difficulty of getting up is large, and size also is difficult to guarantee precisely, thereby does not reach the desired dimensional accuracy of retainer cover plate.And integrally-built punch die is also very high to the requirement of punch press, and enough large work top be arranged, the institute that the blanking pressure of punch press also will guarantee once to thrust on the retainer cover plate is porose.Can be very heavy after unitary mould assembles, can make toward installing on lathe very difficult, and inconvenient debugging, it is larger that key need be purchased large-scale punching apparatus cost.
Summary of the invention
The object of the present invention is to provide a kind of single hole die set, by being fixed on patrix on the punch press pressure head and being fixed on counterdie and the rotation positioning device on work surface of punching machine, solve dimensional accuracy, install very difficult, and the problem of inconvenient debugging.
For achieving the above object, the invention provides a kind of single hole die set, comprise the patrix that is fixed on the punch press pressure head, be fixed on counterdie on work surface of punching machine and suitable rotation positioning device.
Described patrix comprises die shank body, top mold frame, red needle fixed head and red needle, described red needle is placed in described red needle fixed head central authorities, described red needle fixed head is fixedly connected with top mold frame, and red needle and described die shank body coaxially be arranged on the punch press pressure head, with the punch press pressure head, moves up and down.
Described counterdie comprises base plate, lower mold holder and die, and described die is placed in lower mold holder central authorities, and described lower mold holder is placed in an end of base plate upper surface.
Described rotation positioning device comprises positioning disk and locating module, and described locating module is placed in the other end of base plate upper surface; Described positioning disk is placed in the upper surface of die and locating module, is horizontal positioned, and is provided with packing ring between die and locating module, and described packing ring central authorities are equipped with connector, and packing ring becomes to be rotationally connected with the base plate of bottom, with the positioning disk on top, is fixedly connected with; Workpiece is installed in the positioning disk circle outside, and described workpiece upper surface is provided with top board, and described top board is fixedly connected with positioning disk.
The operating frequency of described red needle is consistent with the rotational frequency of rotating mechanism.By simplified, reduce installation difficulty, be convenient to the substep debugging.
Further improvement of the present invention is: described top board has through hole at workpiece opposite position place, is convenient to red needle and directly acts on workpiece, uses manpower and material resources sparingly.
Characteristics of the present invention are simple in structure, and precision is high, can reach the desired dimensional accuracy of retainer cover plate.And used cold stamping die set, both guaranteed the precision of mould, the life-span of also having improved mould.Passed through long-term practice, respond well, meet the needs of production.
