Abstract
The utility model provides a material ejecting structure of a knuckle vertical-forge forging die, which comprises an upper die and a lower die, wherein the upper die is matched with the lower die to form cavities of forged pieces. A stair hole is arranged under the cavity of forged pieces of the lower die, an ejector rod transition board is arranged in an outer hole of the stair hole, the bottom surface of the ejector rod transition board is on the same level with the bottom surface of the lower die, a hole is arranged at the center of the ejector rod transition board, an ejector rod is arranged in an inner hole of the stair hole, a flange is arranged in the middle of the ejector rod, the diameter of the flange is larger than that of the hole at the center of the ejector rod transition board, the lower end face of the flange is contacted with the ejector rod transition board, and the bottom of the ejector rod extends out from the hole at the center of the ejector rod transition board. By using the material ejecting structure of the knuckle vertical-forge forging die, forging pressure born by the ejector rod transition board is acted on the bottom face of a holder for limiting, simultaneously stressed area is enlarged, pressure of unit area of a material ejecting hole accessory of the holder is greatly reduced, and accordingly collapse of the periphery of the material ejecting hole caused by long-time stressing at one position of the holder is avoided.
Description
Technical field
The utility model relates to a kind of forging mold, the upright liftout structure of forging forge die of especially a kind of knuckle.
Background technology
The development of Chinese Automobile Industry ' is constantly risen to high-quality, low-cost forging demand.Knuckle is security personnel's part of automobile front axle steering, is accompanied by the continuous expansion of automobile family, and the knuckle kind is also more and more, and planform also becomes increasingly complex, and causes the moulding difficulty to continue to increase, and forging quality is required to improve constantly.General knuckle part profile is definite when product design, and its optimum molding mode is generally the open die forging, impressing forging that has only a die joint.As far as forging, be exactly to crouch to forge, stand and forge two kinds of orientation.Usually, miniature, light, Medium Truck knuckle adopts the forging process that crouches, and often adopts upright forging process and heavily block knuckle.Knuckle is upright, and bar minister degree is usually by ejector pin of die set control when forging, and lifting surface area is merely the push rod flange area in the bar portion forming process, and this position is long-time stressed to subside near being prone to cause clamper liftout hole, thereby to the short variation that exists of forging bar minister.
Summary of the invention
The purpose of the utility model provides the upright liftout structure of forging forge die of a kind of knuckle; Can solve when existing knuckle is upright to be forged bar minister degree is controlled by ejector pin of die set usually; Lifting surface area is merely the push rod flange area in the bar portion forming process; This position is long-time stressedly to subside near being prone to cause clamper liftout hole, thereby to the short problem that has variation of forging bar minister.
In order to solve the problems of the technologies described above, the technical scheme of the utility model as: the upright liftout structure of forging forge die of a kind of knuckle comprises upper die and lower die; Patrix cooperates the die cavity that forms forging with counterdie; It is characterized in that: the forging die cavity below of said counterdie is provided with stepped hole, is provided with the push rod rebound in the outer hole of stepped hole, and the bottom surface of push rod rebound is concordant with the bottom surface of counterdie; The center of push rod rebound is provided with the hole; Be provided with push rod in the endoporus of stepped hole, the middle part of push rod is provided with flange, and the diameter of flange is greater than the diameter in the hole at push rod rebound center; The lower surface of flange contacts with the push rod rebound, and stretch out in the hole at push rod rebound center the bottom of push rod.
Beneficial effect:
Use the upright liftout structure of forging forge die of the described knuckle of the utility model; When forging forming, forge die is closed, and the push rod rebound has born the forging and pressing active force in the bar portion forming process; Push rod forging force that rebound bears acts on to add and holds on the device bottom surface, plays position-limiting action; Lifting surface area is increased, greatly reduce clamper liftout hole annex unit are pressure, thereby subside near avoiding that this position of clamper is long-time stressed and being prone to cause the liftout hole; Because the flange diameter of push rod is greater than the diameter of bore of push rod rebound in the utility model; Therefore the push rod rebound has position-limiting action; Make push rod receive forging force down during return; Stop motion when push rod touches the push rod rebound makes the down stroke of push rod precisely controlled, makes that forging bar minister degree precision is also precisely controlled.After forging completion, equipment and add and hold the device material jacking mechanism and withstand on the push rod, push rod is through forging part bar portion die cavity guiding down, with the depanning of forging jack-up.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among Fig. 1: 1. patrix, 2. counterdie, 3. push rod, 4. push rod rebound, 5. major part screw.
The specific embodiment
The upright liftout structure of forging forge die of a kind of knuckle of the utility model as shown in Figure 1 comprises patrix 1, counterdie 2, and patrix 1 cooperates the die cavity that forms forging with counterdie 2; The forging die cavity below of said counterdie 2 is provided with stepped hole, through the major part screw push rod rebound 4 is installed in the outer hole of stepped hole, and the bottom surface of push rod rebound 4 is concordant with the bottom surface of counterdie 2; The center of push rod rebound 4 is provided with the hole; Be provided with push rod 3 in the endoporus of stepped hole, the middle part of push rod 3 is provided with flange, and the diameter of flange is greater than the diameter in the hole at push rod rebound 4 centers; The lower surface of flange contacts with push rod rebound 4, and stretch out in the hole at push rod rebound 4 centers the bottom of push rod 3.
