Description
Technical field
The utility model relates to commutator process equipment, is specifically related to a kind of finish draw mould that draws row for commutator segment, is applicable to the processing mode that half bag stretches.
Background technology
So-called half bag stretches, and is that relatively full bag stretches.The traditional row's of drawing mode is said working modulus, calculates exactly allowance, and working modulus is generally between 15%～25%, drawing (stretching) rule is that each face is all put surplus, makes each cross section stressed evenly, specifically, the size of relative 3mm, general allowance can reach 0.3mm left and right; And must all have surplus in each cross section, otherwise can cause drawing problem, as draw inhomogeneous phenomenon.Yet, still there is such-and-such defect in the copper bar drawing completely according to the method out, for example: two trapezoidal always out-of-flatnesses of working face, have the phenomenon that arches upward of circular arc, highly about 0.015mm left and right, this phenomenon should be because in drawing process, each causes to stressed.This arch arc phenomenon is a disadvantageous factor, can make the ring-like arch arc of the integral body unstability of commutator, thereby affect the performance of commutator.
In order to improve the quality of products, eliminate the problem that traditional full bag stretching mode produces, having worked out half bag stretches, the principle that half bag stretches is to make its three stressed (the trapezoidal two sides of commutator segment and planes) and the stretching way of another side (part in commutator segment except trapezium structure) emptying, this way can make the surface (two especially trapezoidal sides) of copper bar quite smooth, and even thickness; The very small cause of surplus simultaneously stretching due to half bag, can also make the life-span of mould significantly improve, thereby reach the object of stabilized product quality.
Because partly the finish draw of bag stretching and the surplus of finishing are very small, so there is strict position degree requirement the direction drawing while drawing and the position of drawing-die, due to copper bar can be on coiled strip cone cylinder when drawing back and forth walk about that (being drawn to some coiled strips can automatically skid off on cone cylinder, the walk about amplitude of wire rod on coiled strip is approximately 50 millimeters), the mould of drawing just must be made the amplitude of oscillation that action correspondingly adapts to its wire rod.Generally, this technique must meet twice connect draw, mould drawing requirement point-blank all the time.
Summary of the invention
The utility model partly wraps in stretching mode mainly for commutator segment, twice connect draw, mould drawing requirement point-blank all the time, invented a kind of finish draw mould that half bag stretches that is specially adapted for, this finish draw mould is provided with finishing die and die finish twice mould, and this twice mould is positioned at same level line, and combine the structures such as rotating shaft and locating slot, can adjust in time the position of mould, can meet the drawing requirement that half bag stretches completely.
Above-mentioned technical problem of the present utility model is implemented by the following technical programs: a kind of finish draw mould that draws row for commutator segment, it is characterized in that, comprise die holder fixed head, on die holder fixed head, be provided with two die holders that front and back are arranged in a straight line, be respectively the first die holder that is positioned at the place ahead, be positioned at second die holder at rear, in the first die holder and all arrange framed in the second die holder, the framed interior finishing die that arranges of the first die holder, the center of finishing die is the finish draw nib arranging according to the contour shape of commutator segment cross section, the framed interior die finish that arranges of the second die holder, the center of die finish is the finishing nib arranging according to the contour shape of commutator segment cross section, size with nib cross section compares, wherein, the width of the trapezoidal portions of finish draw nib is greater than the width of the trapezoidal portions of finishing nib, the width of the remainder of finish draw nib is less than the width of the remainder of finishing nib, and the length of the cross section of finish draw nib is less than the length of the cross section of finishing nib.
The principle that the variation of above-mentioned finishing die nib and die finish mold hole dimension stretches according to half bag arranges, arranging of finishing die nib met the requirement that full bag stretches, the setting of die finish nib has met the requirement that half bag stretches, i.e. the drawing requirement of three bread of trapezoidal two sides and a plane.
The below of die holder fixed head arranges base plate, leading section at die holder fixed head and base plate is provided with a vertical axle sleeve, vertical rotating shaft is set in axle sleeve, on die holder fixed head, be at least provided with the locating slot of the circular arc of one level, this locating slot take rotating shaft as the center of circle, the center line of the first die holder and the second die holder of take is symmetry axis, locating slot up/down perforation, arranges vertical backstay in locating slot.
As preferably, on described die holder fixed head, between two die holders and between base plate, be also provided with cover plate, height adjustable plate, cover plate is positioned at the top of height adjustable plate, and the leading section of base plate, height adjustable plate, cover plate, die holder fixed head is passed in described axle sleeve and rotating shaft from bottom to up successively.
As preferably, the position on described die holder fixed head, between the first die holder and the second die holder is provided with locating slot together, is provided with a backstay in this locating slot, and this backstay is passed down through die holder fixed head and cover plate, is connected to height adjustable plate.
As preferably, on described die holder fixed head, the rear of the second die holder is provided with another road locating slot, in this locating slot, be provided with two backstays, described backstay is passed down through die holder fixed head and cover plate, and the lower end of backstay is against the upper surface of height adjustable plate.
The setting of above-mentioned rotating shaft, circular arc locating slot and fixed pole, has realized the drawing requirement on same straight line all the time of twice mould; In the row's of drawing process, see, (being drawn to some coiled strips can automatically skid off on cone cylinder if occur, to walk up and down copper bar on coiled strip cone cylinder, the walk about amplitude of wire rod on coiled strip is approximately 50 millimeters) phenomenon, rotating shaft, circular arc locating slot and fixed pole cooperatively interact, and can make mould make the amplitude of oscillation that swing correspondingly adapts to its wire rod.
As preferably, on described height adjustable plate, be provided with some screws, screw is down through height adjustable plate, the lower end of screw is against the upper surface of base plate, between height adjustable plate and base plate, retain space, the vertical range between height adjustable plate and base plate regulates by rotating described screw, thereby changes the operation height of finish draw mold integral, or adjust the front and back working face of mould, to adapt to different job requirements.
