Description
Technical Field
The utility model belongs to the technical field of gear machining, refer in particular to an electronic screw press is with open floating forging mould of straight bevel gear.
Background
In straight bevel gear processing production process, on electronic screw press usually, adopt ordinary open die forging straight bevel gear, for guaranteeing that the blank fully deforms, adopt the mode of "just forging + finish forging" usually, just forge promptly and adopt open forging and pressing, carry out the preliminary forging to the blank shape and make, later carry out open finish forging, carry out concrete shaping forging and pressing to the blank of preliminary forging through forming die, above-mentioned blank need can be formed through 2 forgings. Not only two sets of equipment are needed, but also the processing process is complex and the efficiency is influenced; and if the closed forging mode is adopted, although one-step forming can be realized, the price of special equipment required to be invested in closed forging is higher, and the production cost is greatly increased.
Disclosure of Invention
The utility model aims at providing a high and cost-effective open floating forging die of straight bevel gear for electric screw press of machining efficiency, which is not enough for prior art.
The purpose of the utility model is realized like this: the utility model provides an open floating forging mould of straight bevel gear for electronic screw press, includes blank, upper die base and die holder, upper die base bottom be provided with the mould, last mould in be provided with the forge pole, last mould be provided with the stress ring outward, die holder top be provided with the lower mould, last mould and lower mould all be provided with the die cavity, the blank be located the die cavity, the lower mould in be provided with the forge pole down, lower mould bottom be provided with the lower mould backing plate, the lower mould backing plate be provided with the spring assembly, lower mould and lower mould backing plate be provided with down the stress ring outward.
The utility model discloses further optimize to: the lower die base plate is provided with spring holes which are uniformly distributed in the circumferential direction, and the spring group is positioned in the spring holes.
The utility model discloses further optimize to: the upper forging rod is positioned in the middle of the upper die, the lower forging rod is positioned in the middle of the lower die, and the upper forging rod is vertically aligned with the lower forging rod.
The utility model discloses further optimize to: and an upper die base plate is arranged at the top of the upper die in the upper stress ring.
Compared with the prior art, the utility model outstanding and profitable technological effect is: the utility model discloses a mode of open forging that floats compares ordinary open forging, because the effect of spring assembly, there is the process of downstream in the lower mould, at a complete forging in-process, the blank warp and is divided into two stages: in the first stage, similar to the 'initial forging' of common open forging, an upper die screw-receiving press acts downwards, an upper forging rod forges and presses a blank, the deformation speed of the blank in a lower die is slowed down by a spring group at the bottom of the die, the deformation speed of the blank in an upper die is relatively higher, and the blank preferentially fills a bevel gear cavity of the upper die; and in the second stage, after the lower die contacts the lower die base plate, the deformation speed of the blank in the upper die and the lower die is balanced, the upper die further performs finish forging on the blank while filling a lower die cavity, and performs bevel gear forging on the blank.
