Abstract
The utility model discloses a manufacture die for a circular insulation washer, comprising a disc, a threaded rod and at least one cutting knife. The threaded rod is vertical with the disc surface of the disc and is fixedly connected to the center of the disc; a plurality of concentric circles sharing the same center with the disc are engraved on the disc surface of the disc; the disc surface of the disc is radically provided with a run-through sliding chute; and a cutting knife capable of radically moving and locking is vertically installed in the sliding chute. When the disc rotates round the threaded rod, the running path of the cutting knife forms a circle; the position of the cutting knife on the disc can be adjusted through the sliding chute so as to quickly cut a rubber insulation washer into a circular shape with needed size.
Description
Technical field:
The utility model relates to a kind of making mould, and specifically a kind of making is used for the mould of the annular felt pad of transformer ' s type equipment.
Background technology:
Transformer is one of main equipment of power system; its health operation directly affects the stable of electric power system; in present transformer ' s type equipment rebuilding, maintenance construction; run into the situation that main transformer sleeve pipe base, butterfly valve, Buchholz relay bend pipe etc. are located the annular felt pad of changing through regular meeting; find according to transformer site examining and repairing situation; the principal element that influences Repair of Transformer quality and repair time depends on the situation of felt pad; present main transformer felt pad mainly adopts to be made by hand, and traditional method of making by hand is often brought the problem of following several respects:
1, make poor accuracy, construction quality by hand and be difficult to guarantee, during processing annular insulated enclosure pad, with compasses draw, scissors cuts, and carries out processing and manufacturing, the finished product that processes, extremely lack of standardization, effect is also very low, and has problems such as poorly sealed.
2, processing rubber insulation pad difficulty is big, size is difficult to control, during the processing felt pad, often once can not moulding, need constantly finishing, be difficult to grasp the size of felt pad like this, make the random and empirical stronger of insulated enclosure pad mode, not that each Repair of Transformer personnel can both make, can not guarantee 100% good seal performance even if having the insulated enclosure pad that the master craftsman of professional work experience for many years makes.
3, the work efficiency of processing rubber insulation pad is low, influence the major insulation level after main transformer overhauls, when processing the rubber insulation pad by hand, felt pad size is as required made, and needs constantly finishing, inefficiency, when cover is hung in the main transformer overhaul, the time of making and change the rubber insulation pad is longer, causes main transformer core body open-assembly time long like this, influences the major insulation level of main transformer.
4, make the felt pad randomness by force, high material consumption, it is random strong to make felt pad, and manufactured size is difficult to assurance, if on the make error is bigger, causes and does over again, and will strengthen material consumption, the raising cost of overhaul.
The utility model content:
For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of annular felt pad to make mould, be used for improving the making quality of felt pad and increasing work efficiency, reach the purpose that reduces the repair time, the operating condition of transformer ' s type equipment does not take place to influence because of the making quality of insulated enclosure pad and work efficiency.
The utility model technical solution problem adopts following technical scheme:
The annular felt pad is made mould, comprise a disk, one threaded rod and at least one cutter, described threaded rod is vertical with the card of disk and can be fixedly attached to the circle centre position of disk, the card of disk is carved with some concentric circles concentric with disk, and radially offer the chute of perforation in the card of disk, the cutter that can move radially and lock along chute vertically is installed in the described chute.
Design feature of the present utility model also is:
Described cutter is two, and two cutteves form the center symmetry with the center of circle of disk.
The lower end of described threaded rod is coniform, and this end passes the card of disk, and respectively is provided with the nut that disk can be fastened on the threaded rod in the above and below that is positioned at disk on the threaded rod.
Described cutter vertically is installed in the chute of disk, and the above and below that is positioned at disk on the knife bar of cutter respectively is equipped with the clamp nut that cutter can be locked on the disk.
Per two neighboring concentric diameter of a circle difference of being carved in the disk card are 10mm.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, making mould of the present utility model adopts the vertical structure that is connected of a threaded rod and a disk, and in the chute of disk, be provided with two cutteves that are centrosymmetric with circle disk center, when disk when threaded rod rotates, the walking path of cutter just forms a circle, adjust the position of cutter on disk by chute, just can apace valve rubber be cut into the annular of required size.
2, be carved with equably on the card of disk and be spaced apart concentric circles 5mm, concentric with disk, therefore can accurately adjust the position of cutter on disk by chute, also just can accurately cut out the felt pad of required size, draw with existing employing compasses, the method that scissors is cut is compared, both embody rapidity, embodied accuracy again.
3, adopt making die for cutting felt pad of the present utility model, can produce once successfully, avoided being prone to error and causing the situation of reprocessing because of making by hand, reduced the waste of material, improve economic benefit, reduced spending, also improved operating efficiency simultaneously greatly.
4, adopt making mould of the present utility model can cut out the felt pad of required size apace, therefore can reduce the time that the main transformer core body exposes in the maintenance process, improved the dielectric level of main transformer after maintenance.
