Description
Technical field
The utility model relates to metallurgy, machinery manufacturing industry such as steel rolling and heat treatment, particularly the pushing device of a kind of screw body of continuous-type furnace driving.
Background technology
Pushing device is widely used in steel rolling and heat treatment with continuous-type furnace and other occasion that steel billet is moved.
The steel frame guiding mechanism that pushes away of traditional pushing device adopts pilot bar orienting sleeve structure, and pushing away the steel frame pilot bar is the steel round bar of machine up, and base and guide frame are equipped with the copper orienting sleeve, push away the steel frame pilot bar and move in the copper orienting sleeve.Base and guide frame are the cast steel structure, and its weight is heavier, and the manufacturing cycle is long.Base and guide frame, pilot bar and orienting sleeve require all very high aspect processing and assembling.Base need be gone up boring machine processing, and the especially processing of pilot hole, pilot bar to size and Geometrical Tolerance Principle height, has certain degree of difficulty in processing.The guiding movement pair is a sliding friction pair, and mechanical efficiency is lower.Under the big environment of dust, pilot bar and orienting sleeve are influenced by the dust iron scale easily, jam takes place scratch.Push away the steel frame guiding mechanism and adopt rack-and-gear slide rail transmission guide frame sometimes, adopt this structure, when the processing rack-and-gear, need production machine and dedicated tool, all very high to the requirement of processing and assembling, and also manufacturing cost is also high.
The utility model content
Task of the present utility model provides the pushing device that a kind of improved screw body drives, and it has solved, and to push away steel frame machine up, manufacturing cycle long, aspect processing and assembling, require high, difficulty is big, the mechanical problem that efficient is low, manufacturing cost is high of slide-and-guide.
The technical solution of the utility model is as follows:
The pushing device that a kind of screw body drives, it comprises sole plate, pushes away steel frame and pushes away steel toe, guide piece, and Power Drive Unit, described guide piece be the guiding mechanism that constitutes by two rollers up and down to replace slide guide device, four pairs of guide rollers are installed on the base by support; The described steel frame that pushes away is equipped with pilot bar, and base and guide frame are equipped with guide roller, pushes away the steel frame pilot bar and is placed between the guide roller; Described Power Drive Unit is a screw mandrel screw driver train, screw mandrel screw driver train is equipped with screw mandrel shaft block, screw mandrel screw, motor and speed reduction gearing, screw mandrel shaft block has front-end bearing pedestal and rear bearing block, front bearing is play, rear bearing is the radial thrust bearing of mounted in pairs, screw mandrel is connected with speed reduction gearing and motor, screw then with push away steel frame and be connected, push away steel frame and be placed in the guide roller movingly.
Continuous-type furnace pushing device employing of the present utility model is welded to be pushed away steel frame and pushes away steel toe, directly utilizes shaped steel to make guide frame, and the shaped steel material obtains easily, manufacturing structure is simple, also need not carry out machine up, shorten the manufacturing cycle thus, reduce manufacturing cost.
The utility model uses four pair rollers as guiding mechanism, replaces the slide-and-guide mode with the rolling guidance mode.Adopt this structure design, reduced machining amount widely, only need processing parts seldom, low cost of manufacture.Each forms the simple in structure of parts, and low to size and Geometrical Tolerance Principle, processing and manufacturing is more or less freely, assembles easy to adjust quick.Can finish the processing of whole machined piece on middle-size and small-size lathe, tooling cost is low, and equipment manufacturing cost is cheap.Because guiding movement is a roll mode, has reduced friction coefficient, has improved mechanical efficiency, has reduced the energy consumption in the use.
This pushing device adopts the screw body type of drive, and stability when the bearing arrangement design has improved the screw mandrel axially loaded has been eliminated bearing axle that the screw mandrel temperature traverse causes to subsidiary load.
Description of drawings
Fig. 1 is the structural representation of the pushing device of a kind of screw body driving of the present utility model.
Fig. 2 is by A-A cutaway view shown in Figure 1.
The specific embodiment
Referring to Fig. 1 and Fig. 2, the utility model is the pushing device that a kind of screw body drives, and it comprises sole plate 7, pushes away steel frame and pushes away steel toe 1, guide piece and Power Drive Unit.Guide piece is a kind of by two guiding mechanisms that roller 2 constitutes up and down, has replaced traditional pilot bar orienting sleeve/rack-and-gear slide rail transmission guiding mechanism.Four pairs of guide rollers 2 are installed on the base 7 by support 8.
Push away steel frame 1 pilot bar is housed, base 7 and guide frame are equipped with guide roller, push away steel frame 1 pilot bar and are placed between the guide roller.Pushing away steel frame and pushing away steel toe 1 is welded structure, and the guiding leverage is made by rolled section steel such as solid drawn pipe or I-beam section channel-section steels.Base 7 and guide frame are welded structure, and guide frame is made by shaped steel.
Power Drive Unit is a screw mandrel screw driver train.Screw mandrel screw driver train is equipped with screw mandrel shaft block, screw mandrel 5 and screw 4, motor and speed reduction gearing.Screw mandrel shaft block has front-end bearing pedestal 3 and rear bearing block 6, and the front fulcrum bearing can play, and rear bearing adopts the radial thrust bearing of mounted in pairs to be used to bear the beidirectional axial force.Stability when this structure design can improve the screw mandrel axially loaded, the bearing axle that elimination screw mandrel temperature traverse causes is to subsidiary load.
Screw mandrel 5 is connected with speed reduction gearing and motor, 4 of screws with push away steel frame 1 and be connected, push away steel frame 1 and be placed in movingly in the guide roller 2.When pushing device was worked, motor drove screw mandrel 5 through speed reduction gearing and rotates, and screw 4 drives and pushes away steel frame 1 and travel forward in guide roller 2, and then drove to push away steel frame and push away steel toe 1 and promote steel billet and advance.
Last track adjusting wheel in the guide roller 2 is equipped with the holddown spring that track adjusting wheel is fluctuated, and holddown spring is installed, and track adjusting wheel is fluctuated.When track adjusting wheel has certain thrust on guaranteeing, can adjust the gap between the guide wheel voluntarily, guarantee to push away the steel frame easy motion, avoid taking place the jam phenomenon.The cross sectional shape of guide roller 2 is to carry out design-calculated according to the cross sectional shape that pushes away steel frame 1 pilot bar, for example adopts the steel pipe shape.
Certainly, those skilled in the art in the present technique field will be appreciated that, the foregoing description only is to be used for illustrating the utility model, and be not with opposing qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in the scope of the utility model claim conversion, the modification of the foregoing description.
