Abstract
The utility model relates to a valve rod thread rolling die which comprises a machine frame, oil nozzles, a work table and pressing rollers. The number of the pressing rollers is two, and the pressing rollers comprise a fixed pressing roller and a movable pressing roller. The circumferential surface of the fixed pressing roller and the circumferential surface of the movable pressing roller are respectively provided with a threaded structure. The fixed pressing roller is fixed on the machine frame through a pressing roller mounting platform A, the movable pressing roller is connected with the machine frame through a pressing roller mounting platform B. The number of the oil nozzles is two, and the oil nozzles are an oil nozzle A and an oil nozzle B. The oil spraying opening of the oil nozzle A is formed above the fixed pressing roller, and the oil spraying opening of the oil nozzle B is formed above the movable pressing roller. The work table is arranged under a gap between the fixed pressing roller and the movable pressing roller. The work table is driven by a drive device arranged on the machine frame to move up and down, and a fixed support is arranged in front of the work table. The valve rod thread rolling die has the advantages of processing a threaded structure of a valve rod through the two pressing rollers which are sprayed with oil, and being convenient to use, and low in labor intensity of workers.
Description
Technical field
The utility model relates to a kind of valve rod mould of thread, a kind ofly specifically can process easily and efficiently large dry helicitic texture, and the low device of labour intensity.
Background technology
Valve rod is valve vitals, for transmission ，Shang Jie executing agency or handle, below directly band movable valve plug move or rotate, to realize valve switch or regulating action.
Valve rod not still movement parts, stressed member in valve opening and closing process, and be seal.Meanwhile, it is subject to impact and the corrosion of medium, also produces friction with filler.Therefore when selector valve bar material, must guarantee that it has enough intensity, good impact flexibility, resistance to marring, corrosion resistance at the temperature of stipulating.Valve rod is consumable accessory, should also be noted that machining property and the heat treatment performance of material when selecting.
In producing at present, generally adopt the dead technique of car of anti-dandruff mode for the processing of threaded stem, along with the develop rapidly of Mechanical Processing Industry, the performance requirement of double thread is also more and more higher.
Utility model content
The technical problems to be solved in the utility model is to provide a kind ofly can process large dry helicitic texture easily and efficiently, and the low valve rod mould of thread of labour intensity.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of valve rod mould of thread, and its innovative point is: frame, atomizer, workbench, pressure roller and fixed support;
Described pressure roller one has two, be respectively fixedly pressure roller and movable platen, the circumferential surface of described fixedly pressure roller and movable platen is all threaded structure, described fixedly pressure roller is fixed in frame by pressure roller mounting platform A, fixedly between pressure roller and pressure roller mounting platform A, roll and be connected, between pressure roller mounting platform A and frame, be fixedly connected with, described movable platen is connected with frame by pressure roller mounting platform B, and fixedly between pressure roller and movable platen, is relative direction and rotates;
Described atomizer one has two, is respectively atomizer A and atomizer B, and the jet of atomizer A is positioned at the fixedly top of pressure roller, and the jet of atomizer B is positioned at the top of movable platen;
The below in the gap of described fixedly pressure roller and movable platen is provided with workbench, described workbench mainly comprises valve rod placement platform and guide rail, the bottom of guide rail is connected with drive unit, in the upper end of guide rail, is connected with valve rod placement platform, between described guide rail and valve rod placement platform, is slidably connected;
The place ahead of described workbench is provided with a fixed support, and described fixed support is positioned at the outside of frame.
The utility model has the advantage of: utilize two pressure rollers that sprayed oil to process the helicitic texture of valve rod, convenient, fast, whole process is completed by machine, and staff only need be fixed on the valve rod of needs processing on fixed support, has reduced hand labor intensity.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of valve rod mould of thread of the present utility model.
The specific embodiment
Schematic diagram is as shown in Figure 1 known, and valve rod mould of thread of the present utility model mainly comprises frame 12, atomizer, workbench, pressure roller and fixed support 13.
Pressure roller one has two, is respectively fixedly pressure roller 9 and movable platen 4, and fixedly pressure roller 9 is all threaded structure with the outer surface of movable platen 4.
Fixedly pressure roller 9 is fixed in frame 12 by pressure roller mounting platform A11, and fixedly pressure roller 9 is connected by rolling between fixing pressure roller shaft 10 and pressure roller mounting platform A11, and fixedly pressure roller 9 is by motor driving rotation, between pressure roller mounting platform A11 and frame 12, is fixedly connected with; Movable platen 4 is connected with frame 12 by pressure roller mounting platform B3, movable platen 4 is connected by rolling between movable platen axle 5 and pressure roller mounting platform B3, movable platen 4 is driven and is rotated by motor, between pressure roller mounting platform 3B and frame 12, be flexibly connected, pressure roller press-mounting platform 3B is driven by motor, and fixedly between pressure roller 9 and movable platen 4, is relative direction and rotates.
Atomizer one has two, is respectively atomizer A1 and atomizer B2, and the jet of atomizer A1 is positioned at the fixedly top of pressure roller 9, and the jet of atomizer B2 is positioned at the top of movable platen 4.
Below the gap of fixing pressure roller 9 and movable platen 4, be provided with workbench, workbench is driven and is moved up and down by cylinder 8, and cylinder 8 is arranged in frame 12.In the present embodiment, cylinder 8 also can be replaced by oil cylinder or other drive unit.
Workbench mainly comprises valve rod placement platform 6 and guide rail 7, and the bottom of guide rail 7 is connected with cylinder 8, and the upper end of guide rail 7 is provided with valve rod placement platform 6, movable cooperation between valve rod placement platform 6 and guide rail 7.
In the dead ahead of whole workbench, be provided with a fixed support 13, fixed support 13 is for the fixing square toes end of valve rod, and fixed support 13 is positioned at the outside of whole frame 12.
Concrete workflow is: need valve rod to be processed is placed on valve rod placement platform 6 by staff is portable, the square toes end of valve rod is fixed on fixed support 13 places, then by cylinder 8, drive guide rail 7, thereby make valve rod placement platform 6 rise to both medium positions of fixing pressure roller 9 and movable platen 4, pressure roller mounting platform B3 is driven to fixing pressure roller 9 directions and is moved by motor, make fixedly pressure roller 9 just can push down valve rod with movable platen 4, then fixedly pressure roller 9 and movable platen 4 are rotated, start to process the helicitic texture of valve rod, fixedly pressure roller 9 utilizes the oil of atomizer ejection to process stem surface in the process of rotating with movable platen 4 simultaneously, after the several seconds, pressure roller mounting platform B3 is back to original position, cylinder 8 drives workbench to decline simultaneously, machine.
