Description

One kind falls mould
Technical field
The utility model is related to fall mould technical field, more particularly to it is a kind of can drive blank rotate fall mould.
Background technology
With respect to hot-rolled steel, the comprehensive mechanical performance of forged steel is more preferable, is generally used for the works such as high temperature, high pressure, fatigability be strong Under condition.The forging method of forged steel can be divided into flat-die forging, closed die forging and loose tool forging.Closed die forging(Die forging)Refer to Blank is molded using mold and obtain the forging method of forging on special forging equipment.Loose tool forges(Loose tooling forging)It is in freedom It forges using the formed in mould method of activity in equipment, it is the process for forging between open die forging and die forging.Loose tool Forging can obtain that shape is more complicated, the more accurate forging of size compared with open die forging;Compared with die forging, set using open die forging Standby to organize each forging production, loose tool manufacture is easier.The most commonly used is falling mould in loose tool forging, blank needs artificial during forging Rotation, it is uneven due to rotating unstable speed in blank rotation to ensure the quality of loose tooling forging, it be easy to cause and falls die clamp material, falls The problem of mould gets stuck reduces production efficiency, and die life is short.
Utility model content
The purpose of this utility model is to provide one kind to fall mould, to solve the problems, such as blank rotation in the prior art.
In order to solve the above technical problems, the technical solution that the utility model uses is:Including fall on opposed mould, under Mould is fallen, is arranged on down the die holder for falling mould bottom;Fallen on described mould, under fall matched semicircular arc straight slot be relatively set on mould; Fallen on described mould, under fall the quadrangle of mould and be provided with step, blind hole is provided on step, lead, lead are fitted in blind hole It is arranged with spring outside;The die holder side is provided with guide rail, is slided on guide rail and is provided with mould bases;Rotation is provided on the mould bases Symmetrical idler wheel, shaft one end of one of idler wheel are connected with speed reducer, and the other end of speed reducer is provided with motor.
Further, be provided on the die holder and fall the matched groove of mould under, under fall mould and clamp down in a groove.
Further, the both sides that mould is fallen under described are provided with card slot, and the card being adapted to card is provided in the groove of die holder Item;Card slot is fixedly connected with strip using removably.
Further, the provided circumferentially about of the idler wheel has packing layer.
Further, the material of described filler layer is rubber, belt, fiber.
Further, the guide rail both sides are provided with gusset, and gusset upper end is fixedly connected on mould bases.
Further, threaded hole is provided on the gusset, bolt is fitted in threaded hole.
The beneficial effects of the utility model are:1st, in forging, blank with uniform rotation, can improve the Forming Quality of blank, It prevents from falling mould and blocks blank.2nd, the mould bases of blank rotation is driven to be slidably arranged on guide rail, by suitably adjusting the position of mould bases, It can be adapted for the forging of long blank and short blank.3rd, it falls mould and is detachably fixed with die holder and connect, it can be different big with dismounting and change It is small to fall mould mold, it is applied widely.

Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing, to this reality With novel further description.
Such as Fig. 1 --- shown in Fig. 4, the utility model provides one kind and falls mould, including fall on opposed mould 7, under fall mould 12, It is arranged on down the die holder 11 for falling 12 bottom of mould;Fallen on described mould 7, under fall matched semicircular arc straight slot be relatively set on mould 12 18.On fall mould 7, under fall that mould 12 is opposed to form a full circle, hydraulic press moves downward, impinges upon and fall on mould 7, above fall mould 7 to Lower movement, blank 6 it is upper fall mould 7, under fall mould 12 under the action of extrusion forming be forged into round steel.Fallen on described mould 7, under fall mould 12 Quadrangle be provided with step 10, blind hole 17 is provided on step 10, is fitted with lead 9 in blind hole 17, is arranged with outside lead 9 Spring 8.Four leads 9 play the guiding role, and prevent from falling mould in forging, above fall and occur crooked when mould 7 moves downward, influence base Expect 6 molding effect or even since mould is fallen in the too big damage of deviation.Spring 8 is cased with outside lead 9, the both ends of spring 8 are pushed against It falls mould 7 to fall on the step 10 of mould 12 and be welded and fixed under, effect is to fall mould 7 by to bounce, and can prevent from falling 7 bullet of mould upper It flies out when rising.11 side of die holder is provided with guide rail 13, is slided on guide rail 13 and is provided with mould bases 14;It is installed on the mould bases 14 There are two support plate, the both ends of the shaft 5 of idler wheel 4 are installed on the supporting plate by bearing, the shaft 5 one of one of idler wheel 4 End is connected with speed reducer 2, and the other end of speed reducer 2 is provided with motor 1.Motor 1 provides power, after speed reducer 2 is regulated the speed, Blank 6 is driven to rotate under the action of idler wheel 4.The mould bases 14 that blank 6 rotates is driven to be slidably arranged on guide rail 13, by suitably adjusting The position of mould preparation frame 14 can be adapted for the forging of long blank 6 and short blank 6.
Be provided on die holder 11 and fall 12 matched groove 21 of mould under, under fall mould 12 and clamp down in groove 21.Die holder 11 The strip 19 being adapted to card is provided in groove 21, under fall the both sides of mould 12 and be provided with card slot 20, card slot 20 is adopted with strip 19 It is fixedly connected with removably.Under fall mould 12 and be detachably fixed with die holder 11 and connect, can be fallen so that dismounting and change is different size of Mould mold, it is applied widely.
The provided circumferentially about of idler wheel 4 has packing layer 3, and the material of packing layer 3 is rubber, belt, fiber.By setting filler Layer 3 can improve friction coefficient, skid when preventing blank 6 from rotating.While the material of packing layer 3 is rubber, belt, fiber, it is hard Gu durable, service life is long.
13 both sides of guide rail are provided with gusset 15, and 15 upper end of gusset is fixedly connected on mould bases 14.It is additionally provided on gusset 15 Threaded hole is fitted with bolt 16 in threaded hole.Gusset 15 clasps the outside of guide rail 13, can prevent in work mould bases 14 because of vibration Overstep the limit and translate into.Bolt 16 screws and pushes against guide rail 13, and mould bases 14 is fixed firmly on guide rail 13.
The foregoing is merely the preferred embodiments of the utility model, and it does not limit the scope of the patent of the present invention, Every equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is directly or indirectly transported Used in other related technical areas, it is equally included in the patent within the scope of the utility model.
