Abstract
The utility model relates to an upper knockout device of a blade trimming and forming press of a large turbine. The upper knockout device is characterized by comprising knockout drive devices respectively arranged at the upper end face of a press sliding block, wherein each knockout drive mechanism penetrates through the sliding block and is connected with an upper knockout rod, one end of the upper knockout rod is connected with an ejector rod at the periphery of an upper punch positioned below the sliding block, and a knockout ring is fixedly connected to the end part of the ejector rod. The upper knockout device has the advantages that the production efficiency can be greatly improved, an operator is prevented from operating in the high temperature environment, and the labor intensity is lightened. In addition, because the upper knockout device is fixed on the upper end face of the sliding block, a knockout device of a conventional drop press is prevented from being positioned under the sliding block; because the temperature of a workpiece is overhigh, the hidden dangers such as frequent oil leakage and heat loss of the knockout device are caused. The upper knockout device has the characteristics of simple structure, high safety performance, stable running, easiness in maintenance and the like.
Description
Technical field
The utility model belongs to hydraulic machinery technical field, particularly relates to filling device on a kind of large-size steam turbine blade trimming for forming press.
Background technology
Steam turbine is main prime mover of modern thermal power plant and nuclear power plant, and it also can be used as the various large-scale working machines of industry in order to drive such as the thrust power of large ship and warship and metallurgy, chemical industry.Blade is building block important in steam turbine, and how processing vapor turbine blade, all by die-forging forming, can produce thicker overlap when blade forming at present, therefore need to be through secondary compacting trimming.But the overlap major part that trimming produces all can be bonding with press upper punch, is difficult to separation.At present, mainly by manual operation, carry out the separated of profiled member and overlap, but because the profiled member after die forging and overlap are warmware, operating environment temperature is high, causes operator's work under bad environment, labour intensity is large, and has had a strong impact on production efficiency.
Summary of the invention
The utility model for solve the technical problem existing in known technology provide a kind of simple in structure, avoid filling device on large-size steam turbine blade trimming for forming press that workman operates, reduces labor intensity and can enhance productivity under high-temperature severe environment.
The technical scheme that the utility model is taked for the technical problem existing in solution known technology is:
Comprise the dnockout driving mechanism being arranged on respectively on press slide upper surface, described dnockout driving mechanism is through slide block and connect upper knockout rod, described upper knockout rod one end is connected with the push rod that is positioned at slide block below upper punch periphery, and described push rod end is connected with dnockout ring.
The utility model can also adopt following technical scheme:
Described dnockout driving mechanism comprises material-punching cylinder, piston rod and the cylinder mouth guide pin bushing being packed on slide block.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, by this device, can be realized the blade overlap that is bonded in upper punch is quick separated with it and be hit down counterdie, can increase substantially production efficiency; Avoid operating personnel to be under hot environment and operated, alleviated its labour intensity.In addition, because this device is fixed on upper end of slide block face, avoid traditional drop press filling device to be positioned at below slide block, because workpiece temperature is too high, caused the hidden danger such as the frequent leakage of oil of material ramming system and heat waste.This device also has the features such as easy care simple in structure, security performance be high, stable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is the I portion enlarged drawing in Fig. 1.
In figure: 1, material-punching cylinder; 2, piston rod; 3, cylinder mouth guide pin bushing; 4, clamp nut; 5, upper knockout rod; 6, slide block; 7, upper bolster; 8, push rod; 9, dnockout ring; 10, upper punch.
The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1-Fig. 3, filling device on large-size steam turbine blade trimming for forming press, comprise the dnockout driving mechanism being arranged on respectively on press slide 6 upper surfaces, described dnockout driving mechanism is through slide block and be connected with knockout rod 5, described upper knockout rod one end is connected with the push rod 8 that is positioned at slide block below upper punch 10 peripheries, and described push rod end is connected with dnockout ring 9.
In the present embodiment, described dnockout driving mechanism comprises material-punching cylinder 1, piston rod 2 and the cylinder mouth guide pin bushing 3 being packed on slide block, and described cylinder mouth guide pin bushing is fixed on slide block by clamp nut 4.
Operation principle of the present utility model is:
After slide block down completes blade cutting burrs, slide block backhaul, start this device material-punching cylinder 1, piston rod 2 descending and promote knockout rod 5 and push rod 8 descending and eject, then by the dnockout ring 9 of push rod bottom, overlap is laid, now, blade and overlap depart from completely, material-punching cylinder pressure release, knockout rod is return.
