Abstract
The utility model discloses a main tooth die for forging production, comprising a force plug body and a lower die body which are buckled together; both the force plug body and the lower die body are rectangular structures; semi-cylindrical die openings with equal conicity and diameter are respectively arranged on the buckling interface of the force plug body and the lower die body along the axial direction. Ends of the semi-cylindrical die openings respectively thread through the side walls of the force plug body and the lower die body. The main tooth die has the advantages that the force plug body and the lower die body, both provided with semi-cylindrical die openings, are shaped to be rectangular structures, so the bucking interface of the force plug body and the lower die body is large and no U-shaped grab handle is needed when connecting the force plug body and the lower die body, thus not only omitting the original U-shaped grab handle but also reducing one operational personnel. When in work, the operational personnel holds the master gear and disposes the shaft of the master gear into the die openings with one hand and operates the forcing press for forging process with the other hand, thus greatly improving work efficiency of the operational personnel.
Description
Technical field
The utility model relates to the production and processing of bevel gear, especially relates to the main tooth mould in the bevel gear forging production.
Background technology
The main gear shaft of bevel gear mostly is cone axis, and more its production and processing is taked to forge and finished.Employed main tooth mould structure is upper die body and the lower mold body that offers conical cavity at present, and upper and lower die body connects as one by a long lever of horizontally disposed U-shaped.During use, operating personnel's both hands are held the long lever of U-shaped, and another operating personnel one hold master gear main gear shaft is placed in the die cavity, and the operating pressure machine forges processing on the other hand.Therefore, the forging processing of main gear shaft need two people be operated, production efficiency is lower.
The utility model content
The utility model purpose is to provide a kind of forging simple in structure, that only need operating personnel can finish forging processing to produce main tooth mould.
For achieving the above object, the utility model can be taked following technical proposals:
Main tooth mould is produced in forging described in the utility model, it comprises upper die body and the lower mold body that snaps together up and down, described upper die body and lower mold body are respectively rectangular configuration, offer tapering, half-conical phantom chamber that diameter is identical on the buckling surface of upper die body and lower mold body vertically respectively; Pairing upper and lower die body sidewall is run through at the two ends in described half-conical phantom chamber respectively.
The utility model advantage is that the upper and lower die body that offers conical die cavity is set to rectangular configuration, therefore, the buckling surface contact area of upper and lower die body needs to use the long lever of U-shaped to connect greatly and not to be one, this has not only saved the setting of the long lever of existing U-shaped, and has saved operating personnel.During work, only need operating personnel one to hold master gear main gear shaft is placed in the die cavity, proficiency operating pressure machine forges processing and can finish, and has improved operating personnel's production efficiency greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in the figure, main tooth mould is produced in forging described in the utility model, it comprises upper die body and the lower mold body 1,2 that snaps together up and down, described upper die body 1 and lower mold body 2 are respectively rectangular configuration, offer tapering, half- conical phantom chamber 3,4 that diameter is identical on the buckling surface of upper die body 1 and lower mold body 2 vertically respectively; The two ends in described half- conical phantom chamber 3,4 are run through pairing upper die body, lower mold body sidewall respectively.
Claims (1)
