Abstract
The utility model provides an overlap cut off die is forged to straight bevel gear profile of tooth, including press on the straight bevel gear circular bead and have the spill drift of hole on the mould, the upper end has the side cut lower mould that involute profile, lower extreme have the hole. The utility model discloses overlap cut off die is forged to straight bevel gear profile of tooth, the trim, the preparation is easy, and the location is accurate, and production efficiency is high, the lower track process of being convenient for, the cutting resistance is little. But the wide application is in the straight bevel gear manufacture process.
Description
Technical field
The present invention relates to a kind of Straight-tooth Conical Gear Shapes forging overlap edger, can be widely applied in straight bevel gear manufacture process.
Background technology
The teeth portion of existing straight bevel gear, general die-forging forming, burr and overlap is easily remained at big end tooth exterior feature inner edge, when follow-up large end face polish, the cutting flank profil in interrupted shape necessarily continues to produce a certain amount of impulsive force, and removing these process residues is manufacture one of indispensable operation of straight bevel gear. Existing edger, forging location is inaccurate, and forging flash and profile of tooth excision are of poor quality, and easily causes edger damage.
Summary of the invention
It is an object of the invention to provide a kind of remove overlap, make easily, accurate positioning, production efficiency is high, be easy to next procedure processing, Straight-tooth Conical Gear Shapes forging overlap edger that cutting resistance is little.
In order to achieve the above object, Straight-tooth Conical Gear Shapes of the present invention forging overlap edger, including being pressed against on straight bevel gear shoulder and spill with endoporus rushes upper die, upper end with involute profile, lower end with the trimming counterdie of endoporus.
Straight-tooth Conical Gear Shapes of the present invention forging overlap edger, its operation principle is: operationally, spill is rushed upper die and is arranged on fly press, be arranged on by counterdie on helical pressure machine worktable. Bevel gear forging is placed on trimming counterdie, forging cone tooth is corresponding with trimming counterdie involute Cylinder Gear, accurate positioning, trimming counterdie maintains static, press ram moves down, spill is rushed upper die and is moved down strike forging, forging flash departs from gear forgings, forging big end cone tooth is cut with the overlap of trimming counterdie transverse tooth thickness contact position simultaneously, the forging cone big end of tooth is cut out the involute profile identical with trimming counterdie, makes easily, thus end cone tooth involute flank forms chamfering with back cone place greatly, being easy to next procedure processing, cutting resistance is little.
Straight-tooth Conical Gear Shapes of the present invention forging overlap edger, described spill rushes upper die, and there is circular inner hole its lower end, with forging diameter of axle matched in clearance, drift lower surface and forging end contact.
Straight-tooth Conical Gear Shapes of the present invention forging overlap edger, is used for removing straight bevel gear flank and the Periapical forging overlap of tooth, and cone tooth flank forms chamfering with back cone place simultaneously, it is simple to next procedure is processed.
Straight-tooth Conical Gear Shapes of the present invention forging overlap edger a, it is possible to stamping-out, removes forging overlap, improves production efficiency.
Straight-tooth Conical Gear Shapes of the present invention forging overlap edger, the cone big end tooth side of tooth punches out chamfering with back cone junction, it is simple to next procedure is processed.
In sum, Straight-tooth Conical Gear Shapes of the present invention forging overlap edger, to remove overlap, make easily, accurate positioning, production efficiency is high, it is simple to next procedure is processed, and cutting resistance is little.

Detailed description of the invention
In Fig. 1��Fig. 7, Straight-tooth Conical Gear Shapes of the present invention forging overlap edger, including being pressed against on straight bevel gear shoulder and spill with endoporus a rushes upper die 1, upper end with involute profile b, lower end with the trimming counterdie 2 of endoporus c.
Additionally, in figure, Straight Bevel Gear Forgings 3, forge overlap d, forging overlap is removed position e. Forming chamfering at each tooth of bevel gear big end place flank with back cone place, the profile of tooth at big chamfer place is identical with the involute cylinder profile of tooth of trimming counterdie.
