Abstract
The utility model discloses a flange type internal ball cage forging die which comprises an upper die holder, a lower die holder and a lower die plate, wherein the lower die holder is fixedly arranged on the lower die plate, and a die chamber is arranged on the lower die holder; an upper holding die and a lower holding die are fixedly arranged in the die chamber; a concave die in which a step hole is formed is arranged in the upper holding die, and the lower holding die propps against the bottom of the concave die; a through hole is formed in the lower die plate, and is internally provided with a lower propping rod in a sliding fit; an upper propping rod is connected with the end part of the lower propping rod; the lower propping rod upwards passes through the through hole and the lower holding die in sequence, and extends into the concave die, and handle dies are arranged around the upper propping rod; a pedestal is fixedly arranged on the lower surface of the upper die holder; and a T-shaped punch towards the concave die is fixedly arranged on the pedestal through a connecting block. The flange type internal ball cage forging die is reasonable and reliable in structure, and has the capacity of integrally forging and forming an internal chamber of a flange type internal ball cage and a flange at an end port of the flange type internal ball cage, and therefore, the technical process is simplified, the working efficiency is improved, and the forming precision of the flange type internal ball cage is greatly improved.
Description
Technical field
The utility model relates to mould applications, specifically is a kind of flange form internal spherical cage forging mold.
Background technology
The flange form internal spherical cage is a kind of of pivoting constant velocity cardan joint, is made up of foreign steamer and three pivots, and output position direct and differential mechanism links, and is used to transmit the moment of torsion of engine output.The flange form internal spherical cage has simple installation, easy-to-mount characteristics.
Have the flange connecting of being used for around the port of flange form internal spherical cage inner chamber, when forging, generally forge the inner chamber of flange form internal spherical cage earlier; The port of flange form internal spherical cage inner chamber forges flange then; Technology more complicated, and the bad grasp of precision, defect rate is higher.
The utility model content
The purpose of the utility model provides a kind of flange form internal spherical cage forging mold, with the inner chamber of flange form internal spherical cage and the flange one forging molding of its port.
The technical scheme of the utility model is following:
A kind of flange form internal spherical cage forging mold includes upper and lower die holder and lower bolster, and described die shoe is fixedly mounted on the lower bolster; Die shoe is provided with die cavity, it is characterized in that: be installed with upper and lower armful of mould in the described die cavity, described going up in armful mould is provided with die; Be provided with stepped hole in the described die, described following armful mould withstands on the bottom of die, and described lower bolster is provided with through hole; Through hole is interior through the lower push rod that has been slidingly installed; The end of said lower push rod is connected with upper ejector pin, and described upper ejector pin upwards passes through hole and following armful mould successively and extends in the die, around upper ejector pin, is provided with the handle mould; The lower surface of said upper bolster is installed with base, is installed with T type drift through contiguous block on the described base, and described T type drift is towards die.
Described flange form internal spherical cage forging mold is characterized in that: be placed with workpiece in the described die, the oral area of workpiece has flange, and the flange of workpiece is pressed and put on the step surface of stepped hole in die, and the end of said upper ejector pin withstands on the bottom of workpiece.
Described flange form internal spherical cage forging mold is characterized in that: be provided with cushion block between described following armful mould and the lower bolster.
The beneficial effect of the utility model:
The utility model is rational in infrastructure, reliable, can the inner chamber of flange form internal spherical cage and the flange one forging molding of its port have been simplified technological process; Reduced cost; Improved operating efficiency, and the resultant metal streamline that forges is good, has improved the formed precision of flange form internal spherical cage greatly.
