The specific embodiment
Beneficial effect in order more properly to describe the utility model and to bring is described further the utility model below in conjunction with accompanying drawing, but content of the present utility model and protection domain are not limited to the content that the specific embodiment is explained.
In conjunction with Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8 the utility model is described further.
The side cut corrective system of trunnion shaft comprises mould A section and mould B section.
C mould A section comprises: cope match-plate pattern 1; And upper limit position block 2, upper limit position block 2 be fixed in cope match-plate pattern 1 below; Drift 3, drift 3 is fixed in the downside of cope match-plate pattern 1, and is positioned at the inboard of upper limit position block 2.
D mould B section comprises: lower bolster 7; And lower bolster 6, lower bolster 6 be fixed in lower bolster 7 above; And die socket 5; Die socket 5 be fixed in lower bolster 6 above; And lower position block 4, lower position block 4 is fixed on the die socket 5; And trim die 8, trim die 8 is positioned on inboard and the fixing and die socket 55 of lower position block 4, and is provided with the groove 1 of vertical perforation trim die 8; Trim die 8 is used for placing the trunnion shaft B that forged.
Form a cavity A between lower bolster 7, lower bolster 6, die socket 5 and the trim die 8.
D mould B section also comprises lower ejection die 9, and lower ejection die 9 is arranged in cavity A, and can move up and down in cavity A; The upper end 93 of lower ejection die 9 cooperates with groove 1, and can move up and down in groove 1; The upper end 93 of lower ejection die 9 is provided with the groove 2 92 that coincide with trunnion shaft B shape from top to bottom.
Also comprise a base 91, base 91 links to each other with lower ejection cylinder by being located on the lower bolster 7 hole 71, lower ejection die 9 fixing with base 91 on, base 91 ejection die 9 under can driving in cavity A under the active force of lower ejection cylinder moves up and down.
Wherein, when the side cut corrective system was cut edge to trunnion shaft B, lower ejection die 9 did not contact with trunnion shaft B; When the side cut corrective system is finished side cut, upper limit position block 2 and lower position block 4 butts, trunnion shaft B proofreaies and correct shaping by drift 3 and 9 pairs of trunnion shafves of lower ejection die between drift 3 and lower ejection die 9.
During use, first the trunnion shaft B through finish-forging is placed on the trim die 8 of mould B section, trim die 8 is provided with the groove 1 of the described trim die of vertical perforation.The opening pressure machine, the cope match-plate pattern 1 of mould A section drives drift 3 and moves downward, until the trunnion shaft through finish-forging that 3 pairs of drifts are positioned on the trim die 8 is cut edge.
After side cut is finished, drift 3 is taken trunnion shaft B route groove 1 and is continued operation downwards, until patrix limited block 2 and counterdie limited block 4 butts, at this moment, lower ejection die 9 is arranged in cavity A, trunnion shaft B fall into the groove 2 92 of lower ejection die 9 and be in drift 3 and lower ejection die 9 between, at this moment, trunnion shaft B complete packet is contained between drift 3 and the lower ejection die 9, and the remaining kinetic energy that moves downward by drift 3 and in conjunction with the reaction force of lower ejection die 9 is carried out thermal recalibration to trunnion shaft B.
After correction is finished, the thrust that outside forcing press makes progress to base 91, base 91 drives fixing and upwards operation of the lower ejection die on it 9, trunnion shaft B is arranged in the groove 2 92 of lower ejection die 9, the upper end 93 of lower ejection die 9 finally makes trunnion shaft B take out from groove 2 92 through the groove 1 of trim die 8.Wherein, base 91 links to each other with the external pressure machine by hole on the lower bolster 7.After trunnion shaft B was removed, lower ejection die 9 was return among the cavity A again.
Use the utility model to the trunnion shaft timing of cutting edge, workflow is: the corrections of cutting edge of the thick moulding of middle frequency furnace heating → 1000mm automatic roll forging machine roll forging → 4000 tons of friction press bending finish-forging → 1000 tons of friction presses.Required personnel are configured to heat 1 people, automatic roll forging machine group 1 people, and 4000 tons of friction press 2 people, 1000 tons of friction press 2 people, auxiliary turnover 1 people, per tour needs 7 people altogether.Productive temp generally is 2.5 minutes/root.
Because the utility model reduces special correction link one, reduced the equipment investment (price is 1,200,000 yuan) of 1600 tons of friction presses, (1600T friction pressure acc power is 132kWh to have alleviated energy consumption, by a class 8 hours, each class is actual can be saved more than the energy consumption 700kWh), reduced the requirement to personnel amount, and because operation is simplified, can make productive temp be increased to 2.5 minutes/part.
