Description

Multifunction transformer bending machine

Technical field

The utility model relates to transformer production equipment, particularly a kind of bending machine 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 machinery of multiple curved needs.

Utility model content

The purpose of this utility model is to provide a kind of Multifunction transformer bending machine, 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 bending machine, comprises driving wheel, driven pulley, framework, limit stick, regulating block, base plate, follower shaft, drive sprocket axle, spring bearing and action bars; Described framework is made up of parallel framework upper plate and framework lower plate and the framework side plate that is connected both; 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 upper plate and framework lower plate; Described driving wheel is by drive sprocket axle connecting frame upper plate, framework lower plate 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 upper plate and framework lower plate; Described spring bearing is made up of back shaft, two fixed heads, support roller and support sleeves; Described two fixed heads are arranged on framework lower plate bottom, and the two ends of described back shaft are erected on fixed head, and the two ends of back shaft are provided with support sleeve, and described support roller is arranged on back shaft, and support roller rolls and contacts with base plate; Described action bars is connected on framework side plate.

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 detailed description of the invention part below, and part will become obviously from the following description, or recognize by practice of the present utility model.

Detailed description of the invention

Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further.

As shown in Figures 1 to 5, 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 action bars 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.Framework 3 is made up of parallel framework upper plate 15 and framework lower plate 16 and the framework side plate 17 that is connected both.Drive sprocket axle 8 is housed in driving wheel 1, and the framework upper plate 15 and the framework lower plate 16 that are arranged on framework 3 by drive sprocket axle 8 are interior and fixing with base plate 6.Follower shaft 7 is housed in driven pulley 2, is arranged in the framework upper plate 15 and framework lower plate 16 of framework 3 by follower shaft 7, driven pulley 2 can rotate around follower shaft 7 voluntarily.Action bars 10 is arranged on framework side plate 17, and when work, driving wheel 1 is motionless, promotes framework 3 by action bars 10, 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 framework upper plate 15 of follower shaft 7 two ends and framework 3 and the junction of framework lower plate 16, be responsible for regulating the distance of driven pulley 2 and driving wheel 1, while meeting multiple spot bending, ensure first curved can passing smoothly of roll over from the interstitial hole of two rollers.Spring bearing 9 is a rolling bearing, is made up of back shaft 11, two fixed heads 12, support roller 13 and support sleeves 14; Two fixed heads 12 are arranged on framework lower plate 16 bottoms of framework 3, and the two ends of back shaft 11 are erected on fixed head 12, and the two ends of back shaft 11 are provided with support sleeve 14, and support roller 13 is arranged on back shaft 11, and support roller 13 rolls and contacts with base plate 6.Spring bearing 9 plays the effect of support frame 3, can on base plate 6, roll simultaneously, reduces bending labour intensity, ensures principal and subordinate wheel no-float.

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.
