Description
Technical field
The utility model relates to the forging equipment field, relates in particular to a kind of block forging appts.
Background technology
Block forging is a kind of of precision forging technology technology.Be meant that through two unidirectional or out movements with mold or drift, extrusion metal is full of die cavity in the die cavity of sealing, thereby obtain the Forging Technology technology of the near net-shape finish forge spare of non-trimming.Described near closed hollow ring generally is to be formed by the upper die and lower die matched moulds.Different with common closed die forging, extra action and operating pressure motion that block forging need provide except that press slide and the pressure, needed mold clamping force when satisfying the upper and lower mould matched moulds.
The block forging basic principle: shaping dies can divide die to form by upper and lower 2; Put into blank in the mould separated position through the proper volume of primary Calculation; Patrix is closed under the effect of inaccessible power; Low punch is clamp-oned the die cavity of sealing from bottom to top, and the blank material in the die cavity is out of shape under the effect of contraction of the extruding of drift and die cavity and is full of die cavity, finally obtains the accurate blank of the non-trimming that shape and size and die cavity height meet; The patrix backhaul; Last stripping attachment dnockout withdraws from forging from die.
Therefore block forging can be particularly suitable for the production of complex parts once obtaining bigger deflection and complicated profile in the distortion.With the finish forge part in the automobile industry such as gearbox gear, inner race, three bearing pins etc., if adopt the explained hereafter of open die forging, impressing forging, then stock utilization is lower, and follow-up amount of machining is big, and production cost is high.Adopt the block forging technology to produce above-mentioned net-size forging, can save most cut, make cost reduce significantly.Because of its These characteristics, the development in industry parts such as automobile, space flight and aviation are made in recent years very rapidly.
Block forging method commonly used is: on ordinary press, adopt special-purpose inaccessible mould bases to realize block forging production, see accompanying drawing 1; Perhaps use special-purpose occlusion pressure machine, see accompanying drawing 2.
The inaccessible mould bases principle of dedicated hydraulic: the inaccessible mould bases of dedicated hydraulic is made up of upper and lower template and collapsible form, between collapsible form and lower bolster, is equipped with hydraulic pressure or pneumatic inaccessible mechanism, and forming punch is fixedly connected with lower bolster.When forcing press driving sliding block and patrix moved downward, upper and lower die closed up, and lower cavity die receives the high pressure of hydraulic pressure or pneumatic inaccessible mechanism, with the upper cavity die tight closure; Slide block continues when descending, and die and drift form relative motion, reaches the effect that drift is clamp-oned the sealing die.In inaccessible extrusion process, inaccessible oil cylinder or cylinder provide the mold closing power that can divide die closed of keeping.Narrow mostly because of the workbench of general forging type punching machine, the mould bases that is complementary is difficult to hold the oil cylinder or the cylinder of bigger inaccessible power, thus special-purpose inaccessible mould bases only be applicable in, in enormous quantities inaccessible shaping of finding.
Hydraulic pressure block forging forcing press: used occlusion pressure machine is multidirectional hydraulic press mostly, like Fig. 2, generally adopts hydraulic system to realize the multi-directional action of inner and outer slider.Inaccessible power can be done very greatly, is applicable to that the obturation of big part is shaped.Shortcoming is the press structure complicacy, involves great expense, and productive temp is low, and system reliability is bad.
The utility model content
The technical problem that the utility model will solve provides a kind of separate type block forging appts, and it can realize that the obturation of big specification forging is shaped with comparatively simple structure; Manufacturing cost is lower; Actual motion is reliable, is convenient to maintenance, and has higher forging speed and production efficiency.
For solving the problems of the technologies described above; The utility model provides following technical scheme: a kind of separate type block forging appts; Comprise forcing press, inaccessible mould, wherein: inaccessible mechanism separates with inaccessible mould, and inaccessible mechanism passes to a few transmission rod and drives inaccessible mould and carry out obturation and move.
A kind of preferred version as the described separate type block forging appts of the utility model; Wherein: inaccessible mechanism is hydraulic pressure or pneumatic locking device; Be installed in forcing press sill bottom; Inaccessible mould is made up of cope match-plate pattern, lower bolster and collapsible form, and collapsible form is arranged between cope match-plate pattern and the lower bolster, and hydraulic pressure or pneumatic locking device carry out the obturation motion through counterdie and the patrix on the cope match-plate pattern that transmission rod drives on the collapsible form.
A kind of preferred version as the described separate type block forging appts of the utility model; Wherein: inaccessible mechanism is hydraulic pressure or pneumatic locking device; Hydraulic pressure or pneumatic locking device are fixed on the outside of forcing press through external method; Inaccessible mould is installed on cope match-plate pattern, lower bolster and the collapsible form, and collapsible form is arranged between cope match-plate pattern and the lower bolster, and hydraulic pressure or pneumatic locking device form inaccessible motion through counterdie and the patrix that transmission rod drives on the collapsible form.
As a kind of preferred version of the described separate type block forging appts of the utility model, wherein: said external inaccessible oil cylinder is through in the base that is bolted to forcing press or base bottom.
As a kind of preferred version of the described separate type block forging appts of the utility model, wherein: said transmission rod is many, and transmission rod is the multi-segment activity draw bail.
As a kind of preferred version of the described separate type block forging appts of the utility model, wherein: said forcing press sill is provided with at least one pilot sleeve, and said transmission rod places in the pilot sleeve, and two ends connect with inaccessible mechanism and collapsible form respectively.
Adopted the said device of the utility model, it has following useful technique effect: 1. the height that has kept the punching machine prototype forges speed and high efficiency; 2. locking device does not receive the narrow and small restriction of work space, and bigger inaccessible oil cylinder can be installed, and realizes that the obturation of big specification forging is shaped; 3. inaccessible mechanism is away from the mold work space, and obtains protection easily, avoided inaccessible oil cylinder to be forged possible that dust and mold cools down-lubricating fluid pollutes, and is particularly suitable for inaccessible warm forging and inaccessible forge hot production; 4. inaccessible mechanism separates with mould bases fully, and is simple in structure, reliable, is convenient to die change and maintenance.
