Abstract
The invention discloses a lower die seat of sizing die; the lower die seat of sizing die comprises a lower die seat body; the lower die seat body is in a cylindrical shape; the axial middle potion of the lower die seat body is provided with a through hole; the periphery of the through hole is uniformly provided with a plurality of sunk screw holes; the radial edge of the lower die seat body is symmetrically provided with two grooves for fixation. The disclosed lower die seat of sizing die optimizes the structure, reduces the difficulty of manufacturing, increases the strength and rigidity; therefore, the stability is ensured, the product quality is increased, the operation is simple, the positioning is precise, the stability is good, the adjustment and replacement are convenient, the labor intensity is reduced; and a small tonnage press machine can be used for machining, thus greatly increasing the work efficiency.
Description
Technical field
The present invention relates to a kind of shaping mould structure, the structure of refering in particular to the sizing die die shoe that a kind of good stability easily adjusts is improved.
Background technology
Ribbon retainer production technology is primarily of cutting the punch process operation compositions such as ring, shaping, shaping, punching.In whole process, wherein the quality of trimming crudy directly affects the quality after bearing assemble, and therefore the process of trimming just seems particularly important.Ribbon retainer trimming crudy ensures primarily of trimming moulds of industrial equipment, the assembly structure schematic diagram of correcting die and die shoe in accompanying drawing 2 prior art, can find out that correcting die is fixed by screw in the counterbore 5 being placed on die shoe, such upper and lower mould is being just confined in the counterbore 5 of die shoe die during film, not easily automatic capturing, nest is produced inclined when processing retainer, nest pressure is not just, plane is uneven, the light one side of one side is heavy, not easily adjust, and outside dimension when processing die and the counter bore hole diameters dimensional requirement of die shoe mating part strict, make die shoe processing cost high, process-cycle is long, machining accuracy is not easy to ensure, and along with utility time increase, die shoe distortion starts to increase, counter bore hole diameters diminishes, die is coordinated and has a negative impact.Therefore be necessary to improve the structure of sizing die die shoe.
Summary of the invention
For the technical problem of above-mentioned existence, the object of the invention is: propose the sizing die die shoe that a kind of good stability easily adjusts.
Technical solution of the present invention is achieved in that a kind of sizing die die shoe, comprises die shoe main body, and described die shoe main body is cylindrical shape; The axis middle part of described die shoe main body offers through hole; Described through hole periphery is evenly provided with multiple countersunk screw hole; The radial edges symmetry of described die shoe main body offers two fixing grooves.
Preferably, described screw hole has 3.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Sizing die die shoe of the present invention, by the improvement to structure, optimizes Lower die base structure, reduces the manufacture difficulty of die shoe, improve die shoe intensity and rigidity, die shoe quality is guaranteed, and ensure that the stability of die shoe, product quality is improved, and decreases the regulation time of operator, accurate positioning simple to operate, good stability, be convenient to adjustment, be convenient to change, alleviate labour intensity, and the forcing press of little tonnage can be adopted to process, operating efficiency effectively improves.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the sizing die Lower die base structure schematic diagram of prior art;
Accompanying drawing 2 is the top view of the sizing die die shoe of prior art;
Accompanying drawing 3 is the assembling schematic diagram of the sizing die die shoe of prior art;
Accompanying drawing 4 is sizing die Lower die base structure schematic diagram of the present invention;
Accompanying drawing 5 is the top view of sizing die die shoe of the present invention;
Wherein: 1, die shoe body; 2, through hole; 3, countersunk screw hole; 4, groove; 5, counterbore.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described.
The structure of sizing die die shoe of the present invention, as shown in accompanying drawing 4,5, comprises die shoe main body 1, and described die shoe main body 1 is in cylindrical shape; The axis middle part of described die shoe main body 1 offers through hole 2; Described through hole 2 axial periphery is evenly provided with three countersunk screw hole 3; The radial edges symmetry of described die shoe main body 1 offers two fixing grooves 4.
Sizing die Lower die base structure of the present invention, by improving, compared with prior art, eliminates counterbore of the prior art, keep the total height of die shoe constant, die shoe is stressed increases, bulk strength increase, rigidity improves, owing to eliminating counterbore, so can reduce die shoe appearance and size, profile changes into circle by rectangle, the area taking press bench face diminishes, thus can apply on the forcing press of little one-level tonnage, improve efficiency, strong adaptability.When the die shoe assembling of this structure uses, correcting die is fixed by screws on die shoe, such structure makes upper and lower mould when to mould, can the automatic capturing of minute angle, workman, in mold process, strengthens production safety coefficient, and it is inclined not easily to produce nest when processing retainer, the phenomenon that nest pressure is not positive, it is also easy to adjust.Because counterbore cancelled by the die shoe of this structure, make the correcting die that assembles mutually with it require also to relax adding man-hour outside dimension, can machining tolerance be cancelled, be convenient to processing.The manufacturing procedure of die shoe is also much simple, and the profile step before improvement can be cancelled, and the seam size originally coordinated with correcting die also eliminates, and therefore die shoe of the present invention is convenient to processing, reduces processing cost.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
