Description
Technical field
The utility model is related to the processing of retainer, and in particular to a kind of 40CrNiMoA steels square hole retainer pulling eye work
Dress.
Background technology
Existing steel square hole retainer material is mostly using the materials such as brass, mild steel, hardness HB80-B200, hardness compared with
It is low.Its pockets processing mostly by the way of prebored hole-pulling eye processing, when broaching supporting disk 1 used, platen 2 such as Fig. 1,2 institutes
Show；Broaching process is shown in Fig. 3.
Supporting disk is fixed in machine tool fixture, coordinating at upper diameter diameter D1 with workpiece diameter, and platen is placed on workpiece, under
End diameter D1 is in workpiece diameter cooperation, is fastened by the fixing bolt that portal frame above fixture extends, broaching process is as schemed
3, since cutting force F is larger, product is easily deformed.
During broaching, although the cutting speed of wire pulling method is not high, since broaching tool is multitooth tool, participate in simultaneously
The number of teeth of work is more, and the cutting edge for simultaneously participating in cutting is longer, and can be completed in the one action stroke of broaching tool
Slightly --- half essence --- finishes, and 40CrNiMoA steel retainers material hardness is HB276-323, and hardness is higher, therefore is broached
Larger cutting force can be generated in the process, and workpiece Impact direction is parallel with workpiece end face, i.e. radial pull, and workpiece displacement is caused to become
Shape to ensure stability during broaching, preventing broaching tool tipping and fractureing, prevent workpiece from deforming, need to consider to improve tooling.
Utility model content
In order to solve the above technical problems, the purpose of this utility model is to propose a kind of 40CrNiMoA steels square hole retainer
Pulling eye tooling.
The utility model is adopted the following technical scheme that complete above-mentioned purpose：
A kind of 40CrNiMoA steels square hole retainer pulling eye tooling, the pulling eye tooling include supporting disk and platen；
The middle part of the supporting disk upper surface has round boss protruding upward, and the internal diameter phase of the diameter D1 of round boss and workpiece
Cooperation；The middle part of the platen lower face has downwardly projecting round boss；The diameter and branch of the round boss on platen
The diameter of the round boss is identical on tray；Supporting disk set is equipped on the outside of the supporting disk；The outer sheath of the platen
It is equipped with platen set；The internal diameter of the supporting disk set, the internal diameter of platen set are matched with the outer diameter of workpiece；Supporting disk set with
It is collectively formed to place work between round boss on supporting disk between the round boss, described on platen set and platen
The annular groove of part limits workpiece by the supporting disk set, platen set.
The utility model proposes a kind of 40CrNiMoA steels square hole retainer pulling eye tooling, using supporting disk set, platen
It covers that workpiece is controlled to deform, reduces tool wear, control workpiece deformation, improve pocket hole roughness；By on supporting disk
Round boss and platen on round boss workpiece is supported by inside workpiece, and by support plate set and platen set to work
Part is limited, and when carrying out wire pulling method, a part of pulling force is undertaken by supporting disk, platen, support plate set and platen set, simultaneously
The disk set of package workpiece also acts as the effect of limitation workpiece deformation, improves broaching stability, ensure that retainer machining accuracy.

Specific embodiment
The utility model is illustrated with reference to the drawings and specific embodiments：
A kind of 40CrNiMoA steels square hole retainer pulling eye tooling, the pulling eye tooling include supporting disk 1 and platen
2；With reference to Fig. 4, the middle part of 1 upper surface of supporting disk has a round boss protruding upward, and the diameter D1 of round boss with
The internal diameter of workpiece 5 matches；With reference to Fig. 5, the middle part of 2 lower face of platen has downwardly projecting round boss；On platen 2
The diameter of the round boss is identical with the diameter of round boss described on supporting disk 1；The outside of the supporting disk 1 is equipped with branch
Tray set 3；The outside of the platen 2 is equipped with platen set 4；The internal diameter of supporting disk set 3, the internal diameter of platen set 4 are and work
The outer diameter of part 5 matches；With reference to Fig. 6, on supporting disk set 3 and supporting disk 1 between the round boss, platen set 4 with
It is collectively formed to place the annular groove of workpiece 5 between the round boss on platen 2, by the supporting disk set 3, platen
4 pairs of workpiece of set limit.
