Description
One, technical field:
The present invention relates to transformer insulated process equipment and processing method thereof, is a kind of dove shoe bar processing machine and processing method thereof.
Two, background technology:
The cushion block that stay generally is used for Transformer Winding is worn and is joined, and uses stay that cushion block is worn and fits over together.The winding stay is as the mechanical support between the coil on the one hand, the 2nd, be used for fixing the oil clearance cushion block, and it is the main insulation of transformer.Stay is divided into two kinds: T type stay and dove shoe bar.The T-shape stay as shown in Figure 1, dove shoe bar is as shown in Figure 2.
The T-shape stay is to be formed through gluing hot pressing by paperboard strip one by one, has glue-line.And exist thickness to be difficult for the defective that guarantees, easily easily blocks the turn insulation of bad lead at the both sides corner angle of wide of stay.Dove shoe bar is to adopt moulding millboard time processing to form.Have that shrinkage is little, thickness is stable.Tolerance is little, cooperates with cushion block closely, the good advantage of sliding vertically.
Traditional dove shoe bar process equipment is to form by biplate profile milling cutter time processing.As shown in Figure 3.This kind equipment is when the processing stay, and stay can not all cut down, and leaves a little connection at last, after milling cutter to be shut down is return, with the coupling part strip off.Need in time to clear up the cardboard bits on the machine during operation.Specify and see that China Machine Press published " transformer insulated and insulating material " 44-45 page or leaf in 1999.The defective of this equipment is problems such as high material consumption, long processing time, production efficiency be low, of poor quality.This equipment mainly is made up of fuselage, slide carriage, milling cutter transmission and platform binder four parts.Fuselage adopts ironcasting, and both sides are guide rail, and a side is a San shape guide rail, and opposite side is a level gauge.Stud with tooth bar under the level gauge.The milling cutter running part mainly is by two milling cutters, the support of bearing.Slide carriage is to be welded by steel plate.By milling cutter running part, drive system.Drive system is by motor, worm reducer and pair of sprocket.Platform and fuselage link together, and six binder cylinders are fixed on the support.
Three, summary of the invention:
The invention provides a kind of dove shoe bar processing machine and processing method thereof that can improve working (machining) efficiency.
One of technical scheme of the present invention is: a kind ofly be used to process transformer insulated dove shoe bar processing machine, its fuselage comprises blanking platform, milling cutter, feeding roller, discharge roller and unit head, feeding roller is installed in the feed end of blanking platform, discharge roller is installed in the discharge end of blanking platform, the knife face of milling cutter and slotted eye from blanking platform parallel with feedstock direction stretches out, and the angle between the table top of the knife face of milling cutter and blanking platform is 60 °.
Above-mentioned blanking platform preferably has positioning table along feed direction one side.
In above-mentioned positioning table inboard side shield is arranged preferably.
The blade of above-mentioned milling cutter preferably exceeds 10 millimeters of blanking flat surface.
The axis of above-mentioned feeding roller or discharge roller and the angle of feed direction are preferably 87 to 88 °.
Above-mentioned feeding roller rotating ratio discharge roller rotating speed preferably slow 3% to 5%.
On above-mentioned fuselage, dust cleaning apparatus is installed.
Two of technical scheme of the present invention is: the dove shoe bar processing method of the above-mentioned dove shoe of a kind of usefulness bar processing machine, it is undertaken by following step: at first through twice milling flitch is processed into rib shape with milling cutter, secondly through a milling flitch of above-mentioned rib shape is processed into the flitch of two terraced bar shapeds with milling cutter, the chamfering of processing terraced bar shaped flitch then promptly obtains dove shoe bar.
In above-mentioned method, cutting speed is preferably 100 to 150 meters/minute; The amount of feeding is preferably 1.5 to 2.0 meters/minute; Cutting depth is preferably 0.4 to 0.5 millimeter; Flitch thickness is preferably 4 to 8 millimeters.
Advantage of the present invention is: this dove shoe bar processing machine simple and compact structure, and easy for operation; This dove shoe bar processing method has improved production efficiency, has reduced the consumption of flitch in processing technology, compares with the T-shape stay, and its intensity is good, Functionality, quality and appealing design.
