Abstract
The utility model discloses a multifunctional transformer primary line bender, comprising a driving wheel, a driven wheel, a frame, a limiting bar, adjusting blocks, a bottom plate, a driven wheel shaft, a driving wheel shaft, a support bearing and a fixing base; the driving and driven wheels are arranged in the frame and wheel teeth of the driving and driven wheels are matched; round holes of which the diameters are equal to the diameter of a copper pipe to be bent are formed among the wheel teeth; the driven wheel is connected with the frame by the driven wheel shaft; the driving wheel is connected with the frame and the bottom plate by the driving wheel shaft; the limiting bar is arranged on the bottom plate; the adjusting blocks are arranged at two ends, connected with the frame, of the driven wheel shaft; the support bearing is arranged at the bottom of the frame and is in rolling contact with the bottom plate; the fixing base is connected below the bottom plate. The multifunctional transformer primary line bender is simple in operation, and suitable for multi-standard, multipoint and multi-angle bending, the deformation of a bent copper pipe is not larger than 5% by actual use and the once bending needs of the thin-wall copper pipe in the transformer industry can be fully met.
Description
Technical field
The utility model relates to transformer production instrument, particularly a kind of instrument that carries out bending for the copper pipe that the outside primary line of transformer is connected.
Background technology
Along with the quickening of Development of China's Urbanization, the demand of Cast Resin Dry-Type Transformer is increasing, but the copper pipe connecting as the outside primary line of transformer, has plurality of specifications and deposits, and wall thickness is very thin, 0.8-1 millimeter is not etc., and bending angle and quantity are not quite similar, above all situations, often cause gross distortion after copper pipe bending, even drawing crack phenomenon, thus transformer is caused to potential safety hazard.In view of above situation, be badly in need of exploitation one and can make after thin copper pipe bending without obviously distortion, and applicable plurality of specifications uses simultaneously, and meet a copper pipe simultaneously and roll over from different perspectives the instrument of multiple curved needs.
Utility model content
The purpose of this utility model is to provide a kind of Multifunction transformer primary line bending tool, meets the needs of a thin-wall copper pipe multi-angle multiple spot of transformer industry plurality of specifications bending.
The technical solution of the utility model is as follows:
A kind of Multifunction transformer primary line bending tool, comprises driving wheel, driven pulley, framework, limit stick, regulating block, base plate, follower shaft, drive sprocket axle, spring bearing and firm banking; Described driving wheel and driven pulley are arranged in framework, and both gear teeth cooperatively interact, and form and treat the circular hole of the copper pipe equal diameters of bending at wheel between cog; Described driven pulley is by follower shaft connecting frame; Described driving wheel is by drive sprocket axle connecting frame and base plate; Described limit stick is arranged on base plate; Described regulating block is arranged on the junction of follower shaft two ends and framework; Described spring bearing is arranged on base of frame and rolls and contact with base plate; Described base plate below is connected and fixed base.
Its further technical scheme is: on described framework, be connected with action bars.
Its further technical scheme is: on described base plate, be carved with angle mark.
Its further technical scheme is: described firm banking adopts angle steel to be welded, and below is provided with footing fixing hole.
Useful technique effect of the present utility model is:
The utility model is simple to operate, can be applicable to plurality of specifications, multiple spot, multi-angle bending, uses through actual, and after copper pipe bending, deflection is not more than 5 percent, can meet the bending needs of a thin-wall copper pipe of transformer industry completely.
Advantage of the present utility model will provide in the description of specific embodiment part below, and part will become obviously from the following description, or recognize by practice of the present utility model.
Accompanying drawing explanation
Fig. 1 is stereogram of the present utility model.
Fig. 2 is front view of the present utility model.
Fig. 3 is left view of the present utility model.
Fig. 4 is top view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further.
As shown in Figures 1 to 4, the utility model mainly contains driving wheel 1, driven pulley 2, framework 3, limit stick 4, regulating block 5, base plate 6, follower shaft 7, drive sprocket axle 8, spring bearing 9 and firm banking 10 and forms.Driving wheel 1 and driven pulley 2 are contained in framework 3, and both gear teeth complement each other to form and the circular hole of copper pipe equal diameters for the treatment of bending.Drive sprocket axle 8 is housed in driving wheel 1, is arranged in framework 3 and with base plate 6 and fixes by drive sprocket axle 8.Follower shaft 7 is housed in driven pulley 2, is arranged in framework 3 by follower shaft 7, driven pulley 2 can rotate around follower shaft 7 voluntarily.When work, driving wheel 1 is motionless, promotes framework 3 by action bars 11, drives driven pulley 2 to roll along driving wheel 1, thereby can effectively avoid damaging copper pipe.Limit stick 4 is arranged on base plate 6, for bearing the reaction force producing when copper pipe bends.Regulating block 5 is arranged on the junction of follower shaft 7 two ends and framework 3, is responsible for regulating the distance of driven pulley 2 and driving wheel 1, while meeting multiple spot bending, guarantees first curved can passing smoothly of roll over from the interstitial hole of two rollers.On base plate 6, there is scale marker, can bend as required different angles.Spring bearing 9 is a rolling bearing, is arranged on framework 3 bottoms, plays support frame 3, can on base plate 6, roll simultaneously, reduces bending labour intensity, guarantees principal and subordinate wheel no-float.Firm banking 10 is connected to base plate 6 belows, adopts angle steel to be welded, under have footing fixing hole, convenient fixing, highly moderate, the suitable people operation of standing.
Cardinal principle of the present utility model is that copper pipe passes from the middle circular hole of driving wheel 1 and driven pulley 2, circular hole and copper pipe no-float, and copper pipe uniform stressed in a circumferential direction when bending, avoids causing copper pipe distortion because of local pressure.The utility model can meet 20 millimeters of diameter phi 12, φ 16, φ, and the copper pipe bending of wall thickness 0.8-1 millimeter can multi-angle multiple spot bending and without obviously distortion.
Above-described is only preferred embodiment of the present utility model, and the utility model is not limited to above embodiment.Be appreciated that the oher improvements and changes that those skilled in the art directly derive or associate under the prerequisite that does not depart from basic conception of the present utility model, within all should thinking and being included in protection domain of the present utility model.
