Description
Technical field
The utility model relates to a kind of mould, is specifically related to a kind of busbar rounding mould.
Background technology
In order to solve busbar wedge angle electric discharge phenomena, conventional 10kV and the busbar termination in the above high-voltage board all need rounding.Traditional rounding method has two kinds: the one, through common angle cutting mold the right angle at busbar two ends is cut into circular arc; Through the manual grinding finishing, the operation of this method is numerous and diverse then, and the end face of busbar can not be cut into fillet; The circular arc of pouring out is difficult to the limit of end face tangent, forms new tip easily; The 2nd, through milling machine two right angles of copper bar are milled (as shown in Figure 6), this method length consuming time, cost is high, and the end face of same busbar can not be cut into fillet, can only polish through manual filing, and operation is numerous and diverse.
The utility model content
The purpose of the utility model is the deficiency that overcomes in the above-mentioned background technology, and a kind of busbar rounding mould is provided, and this mould should be able to be apace falls into fillet with two right angles of busbar and end face, and has characteristics simple in structure, easy to use.
For realizing above purpose, the technical scheme below the utility model has adopted:
Busbar rounding mould; It is characterized in that: said mould comprises up and down in opposite directions and right top board and fillet counterdie; The upper surface of top board is being fixed the cross-shaped pressing plate that is used to connect driving mechanism; Lower surface is being fixed the fillet patrix, and the upper surface of fillet counterdie is fixed with four leads that are used to locate said top board, and said lead is vertically arranged; Be set with the back-moving spring that said top board is applied upward pressure on wherein any two leads that are diagonal, the top of lead is equipped with adjusting nut; The upper surface of the lower surface of said fillet patrix and fillet counterdie respectively is provided with one in opposite directions and right cutting knife; First fillet that radius is R is fallen in the left and right sides of cutting knife; Two first fillets are tangent with the edge on busbar left side and right side respectively; And second fillet that arbitrary cross section of said cutting knife all has radius to equate with busbar both sides radius of corner r, the circle that it is r that the arc length of said second fillet equals 1/4 radius; The cutting edge of two cutting knifes in opposite directions and right.
Said cutting knife both sides respectively are provided with a leading edge to the busbar guiding, and two leading edges are parallel with the right edge edge with the busbar left side with respectively.
Be provided with in addition on the said fillet counterdie the left locating piece of busbar guiding, right locating piece and back locating piece; Said left locating piece and right locating piece are separately positioned on the anterior left and right sides of fillet counterdie; Spacing between the two is greater than the Breadth Maximum 0.5-2cm of busbar, and both symmetrical center line overlap with the symmetrical center line of cutting knife; Said back locating piece is fixed on the cutting knife rear side, and its symmetrical center line overlaps with the symmetrical center line of cutting knife.
The operation principle of the utility model is: (between two leads) are stretched in the termination of busbar between the left and right locating piece, through the guiding of leading edge, the end face until the termination arrives to the back locating piece.Driving mechanism is depressed the fillet patrix then; Two cutting knifes can be with a chamfering moulding of end face of busbar up and down; Because two first fillets are tangent with the edge on busbar left side and right side respectively; And the circle that it is r that the arc length of second fillet equals 1/4 radius, so moulding busbar end face slick and sly (as shown in Figure 7) just can reach technological requirement through a spot of burr of repairing.
The beneficial effect of the utility model is: the utility model utilizes cutting knife with the chamfering moulding in busbar termination, can make the busbar termination slick and sly a little after the polishing, can not produce the tip, solves busbar wedge angle electric discharge phenomena; And high efficiency can reduce operating personnel greatly and work strong many.In addition, this apparatus structure is simple, and is cheap, has vast market and is worth.

The specific embodiment
Below in conjunction with Figure of description, the utility model is described further, but the utility model is not limited to following examples.
As shown in Figure 1; The described busbar rounding of the utility model mould; Comprise top board 2, fillet patrix 3 and fillet counterdie 8 from top to bottom in regular turn, said top board and fillet counterdie are in opposite directions and right, and the fillet patrix is fixed on the lower surface of top board; The lower surface of top board is fixed with cross-shaped pressing plate 1, and said top board can be installed on hydraulic press or the milling machine.Four angles of said fillet counterdie are fixed with four leads 5 straight up; Four angles of top board are shaped on locating hole (omit and do not draw); Four leads pass four corresponding locating holes, make top board to be set with the upwards back-moving spring 10 of roof pressure top board on the lead along easy motion about the lead; Back-moving spring can be installed on any two leads that are diagonal; Also can respectively install one, specifically confirm that according to actual conditions the top of lead is equipped with adjusting nut 11 at four leads.
The upper surface of the lower surface of said fillet patrix and fillet counterdie respectively be provided with one in opposite directions and the cutting edge of right 7, two cutting knifes of cutting knife in opposite directions and right.Shown in Figure 5 is the shape of cutting knife; First fillet that maximum radius is R (center of circle is positioned at a side of busbar termination) is fallen in the left and right sides of this cutting knife; In fact, the circle that it is R that the arc length of said first fillet equals 1/4 radius, therefore; The maximum radius place of first fillet and its maximum width at of busbar tangent (shape of busbar such as Fig. 6, shown in Figure 7, its dual-side is along also being rounded down).For fillet is led in the termination of busbar; Second fillet (center of circle is positioned at a side of busbar termination) that arbitrary cross section of said cutting knife all has radius to equate with busbar both sides radius of corner r; In like manner, the arc length of said second fillet circle that also to equal 1/4 radius be r.Obviously, the height of cutting knife can be greater than the radius r of second fillet, only needs to keep the end face and the second fillet smooth transition, between do not have wedge angle to get final product.The radius R of said first fillet can be confirmed according to the actual size of busbar.
Produce for ease; Said cutting knife both sides respectively are provided with a leading edge 12 to the busbar guiding; One end of guide edge is supporting the end points of cutting knife first fillet; The other end is parallel with the busbar edge, perhaps with towards the outer tilt 5-15 degree at busbar edge (specifically confirming) according to actual conditions to form a diminishing opening; Said guide edge also can be made into the location that is beneficial to busbar with the similar structure of cutting knife.
In addition; Also be provided with left locating piece 9, right locating piece 6 and back locating piece 4 on the said fillet counterdie to the busbar guiding; Said left locating piece and right locating piece are separately positioned on the anterior left and right sides of fillet counterdie; Spacing between the two is greater than the Breadth Maximum 0.5-2cm (specifically confirming according to actual conditions) of busbar, and both symmetrical center line overlap with the symmetrical center line of cutting knife; Said back locating piece is fixed on the cutting knife rear side, and its symmetrical center line overlaps with the symmetrical center line of cutting knife.
In the utility model, said cutting knife can select for use high-intensity alloy material to make; Spacing between two cutting knifes is according to the thickness decision of busbar.
