Description

A kind of bent axle trimming correcting integrating mould bases
Technical field
The utility model is related to a kind of bent axle trimming correcting integrating mould bases for the field of forging.
Background technology
Automobile-used steel crankshaft part is generally processed using forging technology.In forging process, due to production technology Reason, forge piece inevitably produces overlap, therefore in order to ensure that parts of Casting quality needs to cut off part;Together When be also required to that the forging after excision overlap is built and is corrected.
Existing bent axle trimming correction process, is carried out step by step the need for having, and can so increase processing step, delay produce into Degree, reduces production efficiency, and can cause the waste of the energy;And the technology that bent axle trimming and correcting integrating are molded is used, also due to Set of molds structure design it is unreasonable, can cause set of molds serious wear, influence the service life of set of molds.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of bent axle trimming correcting integrating mould Frame, its compact conformation, is easily achieved, and can realize that forging trimming correction is once synchronously completed, and effectively improve mould bases Service life.
Realizing a kind of technical scheme of above-mentioned purpose is:A kind of bent axle trimming correcting integrating mould bases, including upper die plate, under Template, upper bolster, die shoe and the mould structure being arranged between upper bolster and die shoe;
The upper die plate and the lower template are connected with pressing equipment respectively, are provided with the center of the upper die plate Backpressure-device, the backpressure-device is connected with cooling device;The upper bolster is removably connected with the upper die plate, it is described under Die holder is removably connected with the lower template, and the upper bolster and the die shoe are connected by symmetrically arranged two guide pillars Connect;
The mould structure includes upper punch, cavity plate, low punch, stripper;The cavity plate is fixed on the upper bolster; The upper punch is arranged in the cavity plate, and the backpressure-device is connected through the upper bolster with the upper punch;Under described Drift is arranged on the die shoe, and the stripper is arranged on the die shoe, positioned at the both sides of the low punch.
Selected as one kind, the backpressure-device is nitrogen spring, the nitrogen spring is cooled down using compressed air.
Alternatively, the backpressure-device is hydraulic die cushion, and the hydraulic die cushion is cooled down by Hydraulic Station.
Further, the guide pillar is provided with guide column sleeve with the connecting portion of the upper bolster.
A kind of axle trimming correcting integrating mould bases of the present utility model, by upper die plate, lower template and mould structure, realizes Once synchronously completing for forging trimming correction, improves production efficiency;Mould structure is installed using inversion type, and cavity plate is set On upper bolster, the upper punch being connected with back pressure original paper is provided with, makes full use of gravitational effect, so as to improve making for cavity plate Use the life-span;Backpressure-device and the cooling device connection of the supporting installation of upper die plate, so as to improve the service life of backpressure-device.
Brief description of the drawings
Fig. 1 is a kind of structural representation of bent axle trimming correcting integrating mould bases of the present utility model.
Specific embodiment
In order to be able to preferably understand the technical solution of the utility model, below by specifically embodiment and combine Accompanying drawing is described in detail:
Refer to Fig. 1, a kind of bent axle trimming correcting integrating mould bases, including upper die plate 1, lower template 2, upper bolster 3, lower mould Seat 4 and the mould structure being arranged between upper bolster 3 and die shoe 4.
Upper die plate 1 and lower template 2 are connected by screw with pressing equipment respectively, and back pressure is provided with the center of upper die plate 1 Equipment, in the present embodiment, backpressure-device employs nitrogen spring 5.In order to ensure the service life of nitrogen spring, it is necessary to nitrogen Gas spring 3 is cooled down, therefore nitrogen spring 3 is connected with pneumatic plant.Except nitrogen spring, backpressure-device equally can be with Hydraulic die cushion is used, and hydraulic die cushion needs to be connected to be cooled down with Hydraulic Station.
Upper bolster 3 is removably connected with upper die plate 1, and die shoe 4 is removably connected with lower template 2, works as mould structure After reaching service life, can by upper and lower die holder from last year template integral demounting, overhauled and substituted, improve the inspection of equipment Repair efficiency.Upper bolster 3 and die shoe 4 are connected by symmetrically arranged two guide pillars 6.Set with the connecting portion of upper bolster 3 in guide pillar 6 There is guide column sleeve 61, to increase bonding strength and longitudinal holding power.
Mould structure includes upper punch 71, cavity plate 72, low punch 73, stripper 74.Cavity plate 72 is fixed on upper bolster, on Drift 71 is arranged in cavity plate 72, and nitrogen spring 5 is connected through upper bolster 3 with upper punch 71.Low punch 73 is arranged on die shoe 4 On, stripper 74 is arranged on die shoe 4, positioned at the both sides of low punch 73.Trimming correcting integrating mould bases of the present utility model Can realize that forging trimming correction is once synchronously completed;It is arranged on upper bolster using cavity plate, stripper is set on die shoe Inversion type mould structure design, can make full use of gravitational effect to carry out forging process, reduce impact of the back pressure for equipment, energy The physical life of enough effectively lifting trim dies.
When carrying out forging process using bent axle trimming correcting integrating mould bases of the present utility model, forging is placed on undershoot On first 73, sliding block declines, and cavity plate 72 from low punch 73 press from both sides the cutting burrs of forging, forging to walk, and stripper 74 rises will be winged Side folder is walked.During trimming, upper punch 71 is clamped forging and is slided in cavity plate 72 with low punch 73, and trimming and correction are once complete Into.
Those of ordinary skill in the art is it should be appreciated that the embodiment of the above is intended merely to illustrate that this practicality is new Type, and be not used as be to restriction of the present utility model, if in spirit of the present utility model, to the above Change, the modification of embodiment will all fall in Claims scope of the present utility model.
