Description
Technical field
The present invention relates to die forging bent axle, connecting rod shaving die device, particularly to die forging bent axle, connecting rod shaving die
The improvement for unloading deburring device of device.
Background technology
Forging part mould-dividing mode is plane and space curved surface, and forging part is of different sizes, species is various, complex-shaped, especially
It is that its point of mould of bent axle is curved surface.
Using trimming is carried out under hot, the upper male mould of shaving die is coordinated with lower cavity die carries out trimming to forging to forging part,
Upper male mould is completed after trimming into lower cavity die, is tended to occur cut overlap and is embraced on upper male mould, so in shaving die
It is provided with upper die plate and unloads deburring device, in upper male mould reset up with upper die plate, unloads the overlap that deburring device pushing and withstanding cuts,
Overlap is unloaded from upper male mould.
To be that a kind of elasticity is board-like unload deburring device to the deburring device that unloads on prior art shaving die device, and which is by being arranged on
On upper die plate and be distributed in upper male mould periphery four guide pillars, be connected to the discharging top board of guide pillar lower end, on guide pillar
Spring is constituted, in the through hole opened in the middle part of the bottom insertion discharging top board of upper male mould.
When upper die plate is descending, upper male mould coordinates overlap to forging to carry out trimming with lower cavity die with upper die plate is descending, together
When unload the discharging top board of deburring device and act on, upper male mould is descending extend into lower cavity die in complete to cut
Up with upper die plate after overlap down stroke, cut overlap embraces, discharging top together up with upper male mould in appearance in upper male mould
Plate is in the presence of its spring pressure（It is descending with respect to upper male mould）Pushing and withstanding overlap, lays down embracing under flash push on upper male mould.
The shortcoming deficiency of the prior art is：
1 discharging top board is monoblock type massive plate, and the size of discharging top board is greater than forging, the bigger discharging top board size of forging
Also bigger, not only the space of weight and occupancy is big, and can not be general, and to each, forging of different sizes needs to configure size pair
That what is answered unloads plate, and carries out replacing handling.
2 scope of applications are little, are confined to simple shape and the forging part for plane mould-dividing mode, for three-dimensional point of mode structure
Forging part, particularly bent axle is very inapplicable.
The space that 3 discharging top boards take is big, affects the placement of forging, is restricted the placement space of forging.
During 4 installation mold, it has not been convenient to adjust upper male mould position, affect the installation site that upper male mould is coordinated with lower cavity die and adjust
It is whole.
5 in process of production, if upper male mould will be repaired, needs first to pull down discharging top board just carry out.
The content of the invention
The purpose of the present invention is for above-mentioned the deficiencies in the prior art, there is provided a kind of simple structure, generally applicable, easy to use
Shaving die device, particularly shaving die unload deburring device improvement, fully meet the forging parts such as die forging bent axle, connecting rod and cut
Side uses.
Shaving die device of the present invention, including upper die plate 11, upper male mould 12, lower cavity die 13, die lower bolster 14, unload overlap
Device is constituted, and upper male mould 12 is fixedly mounted on upper die plate 11, and lower cavity die 13 is arranged on die lower bolster 14, be it is characterized in that
Be distributed with upper die plate 11 it is multiple unload deburring device 3, unload deburring device 3 and be made up of inner sleeve 4, overcoat 5, spring 6, ejection block 7,
The upper end of inner sleeve 4 is fixedly mounted with upper die plate 11, and overcoat 5 is slided and spacing cooperation with inner sleeve 4, in the slip of overcoat 5 and inner sleeve 4
Mating surface is provided with rotation-preventing mechanism, and spring 6 is in inner sleeve 4 and pressure is acted on overcoat 5, on the lower surface of overcoat 5
It is connected by screw ejection block 7 to constitute, forms inner-outer sleeve Combined elastic and unload deburring device.
It is according to the size and shape for being trimmed forging part when the present invention is used, two or more in 11 distributing installation of upper die plate
Deburring device 3 is unloaded, for point mould is the forging part such as bent axle forging part of curve, Ke Yitong due to overlap not at grade
The height that adjustment is connected to the ejection block 7 on 5 lower surface of overcoat is crossed, makes the ejection block 7 for respectively unloading deburring device 3 each with forging part
Place's overlap contact, keeps synchronous and overlap applying 33 active force of spring is pushed.
Side die device of the present invention unloads 3 simple structure of deburring device, and small volume, installation number and position are adjustable, make
With convenient, do not affected by forging part complex-shaped degree and size change, it is generally applicable, adjust simple and convenient, adapt to various
Forging part, the very irregular bent axle forging part of particularly suitable shape, the space of occupancy are little, do not affect the placement of forging, make forging
Placement space more open, increase the spatial altitude for placing forging, can accordingly reduce the overall high of shaving die device
Degree, does not impact when loading and unloading and adjust upper male mould position, when edger is installed, is easy to operator to estimate from any angle
With the gap of adjustment trimming punch and matrix, convenient maintenance upper male mould.
Description of the drawings
It is embodiment of the present invention structural representation that Fig. 1 is figure, and its left and right two parts is not illustrated on upper die plate 11
Punch 12 and unload when deburring device 3 is moved up and down with upper die plate 11 in different station situations.
It is to unload 3 example structure schematic diagram of deburring device that Fig. 2 is figure.
Fig. 3 is the A-A sectional views of Fig. 1, which show multiple 3 distributing installations of deburring device that unload in upper die plate 11 and bent axle mould
Forging uses cooperatively state.
