Abstract
The invention relates to a die for trimming a large turbine blade. The die for trimming the large turbine blade comprises an upper die base, an upper punch, a lower die base and a lower punch, wherein the upper die base is connected with a slider; and the lower die base is arranged on a movable worktable. The die for trimming the large turbine blade is characterized in that the upper end of the upper punch is fixed with the middle of the upper die base; guide sleeves are respectively arranged at two ends of the upper die base; die changing clamps are respectively arranged on the outer sides of the two guide sleeves of the upper die base; a cavity for accommodating a discharging trolley and a workpiece tray is formed in the lower die base; and guiding columns which are matched with the two guide sleeves of the upper die base are arranged at two ends of the lower die base. The die for trimming the large turbine blade has the advantages that the die is simple in structure, die changing operation is quick, easy, convenient, safe and reliable, the production efficiency is improved greatly, the machining cost of the turbine blade is reduced, and requirements on modernization production of the turbine blade are met.
Description
Technical field
The invention belongs to hydraulic machinery technical field, particularly relate to a kind of large-size steam turbine blade trimming mould.
Background technology
Steam turbine is main prime mover of modern thermal power plant and nuclear power plant, and it also can be used as thrust power and the various large-scale working machine of the industry such as metallurgy, chemical industry in order to drive of large ship and warship.Blade is building block important in steam turbine, reprocess through press after the many employing castings of processing mode that turbine blade is traditional, and the mould structure of its press process equipment is generally that upper punch lower end and upper bolster are fixed, when drift changed by needs, hold-down screw need be dismantled by operating personnel from below, in order to prevent the upper punch when dismantling from dropping, also need to be hung by upper punch by boom hoisting, then operating personnel pierce in press and carry out die change.The operation of above-mentioned die change not only loaded down with trivial details, waste time and energy, and there is potential safety hazard.
Summary of the invention
The present invention for solve in known technology the technical problem that exists and provide a kind of structure simple, be convenient to quick die change operation and safe and reliable large-size steam turbine blade trimming mould.
The technical scheme that the present invention takes for the technical problem existed in solution known technology is:
Large-size steam turbine blade trimming mould, comprise be connected with slide block upper bolster, upper punch, be arranged on die shoe on travelling table and low punch, described upper punch upper end and upper bolster middle part are fixed, respectively guide pin bushing is housed at described upper bolster two ends, is positioned at outside upper bolster two guide pin bushing and is provided with die change binding clasp; Be shaped with the cavity for putting out trolley and tray for work pieces in described die shoe, the lead matched with upper bolster two guide pin bushing is housed at described die shoe two ends.
Described die change binding clasp realizes that upper/lower die and slide block and travelling table are fixing fast to depart from.
The advantage that the present invention has and good effect are: because the present invention adopts technique scheme, when namely needing to change dismounting upper punch, first upper bolster is placed on die shoe, open the die change binding clasp at upper bolster two ends, then upper bolster is made to be separated with press, dismantle the trip bolt of upper bolster and upper punch again, can realize safely and fast replace with drift.This mould structure is simple, die change operation is fast and convenient, safe and reliable, increases substantially production efficiency, reduces turbine Blade Machining cost, and then meet turbine blade modern production demand.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1, upper bolster; 2, die change binding clasp; 3 guide pin bushings; 4, upper punch; 5, low punch; 6, lead; 7, die shoe; 7-1, cavity; 8, adjustment block.
Detailed description of the invention
For summary of the invention of the present invention, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, large-size steam turbine blade trimming mould, comprise be connected with slide block upper bolster 1, upper punch 4, be arranged on die shoe 7 on travelling table and low punch 5.Described upper punch upper end and upper bolster middle part are fixed by screw, at described upper bolster two ends, guide pin bushing 3 are housed respectively, are positioned at outside upper bolster two guide pin bushing and are provided with die change binding clasp 2.
In the present embodiment, described die change binding clasp realizes that upper/lower die and slide block and travelling table are fixing fast to depart from.
Be shaped with the cavity 7-1 for putting out trolley and tray for work pieces in described die shoe, the lead 6 matched with upper bolster two guide pin bushing is housed at described die shoe two ends.Described low punch 5 is contained on die shoe, and is fixed by adjustment block 8 and die shoe.
Operation principle of the present invention is:
When needs change dismounting upper punch time, first upper bolster is placed on die shoe, opens the die change binding clasp 2 at upper bolster two ends, then make upper bolster be separated with press, then dismantle the trip bolt of upper bolster and upper punch, can realize safely and fast replace with drift.
