Description
Technical field
The utility model belongs in the flange production process of cylinder (housing) branched hole of aluminium, Steel material, can realize directly cylindrical shell being carried out cold flange in the turn-up process, do not need cylindrical shell is carried out preheating procedure, once realize flanging process, and a kind of device that the flange effect is good is particularly about a kind of Shells of High Voltage Switches branched hole flanging die device.
Background technology
The flanging die device of cylinder (housing) branched hole of GIS product aluminium, Steel material, the flange that is mainly used in cylinder (housing) branched hole of high-voltage switch gear GIS product aluminium, Steel material makes it reach instructions for use.
The Tiebar structure of common original flanging die device is to be processed into external splines (360 ° of quarters of spline) at rod end, and distributes three layers on the short transverse, mainly is the intensity for reinforced pull rod.But such Structural Design Requirement pull bar, the spline machining accuracy of punch are very high, the fit dimension on the especially inside and outside spline short transverse, otherwise the extension mould that affects both cooperates.In addition, external splines has three layers, the contact area that can increase pull bar and punch in theory, thereby increase the intensity of pull bar, but in actual turn-up process, can not guarantee desirable cooperation of every one deck spline between pull bar and the punch, both contacts often become a contact, use for a long time, aggravated on the contrary the destruction to pull bar.
In addition, punch and matrix fillet design originally is lack of standardization, does not have unified standard, and often randomness is very large, causes the housing flange to produce easily the bad phenomenon such as drawing crack, vertical edge are not straight.
The utility model content
The bad phenomenon such as the purpose of this utility model provides a kind of Shells of High Voltage Switches branched hole flanging die device, and its standard reasonable in design is processed simply, uses reliably, has solved the housing flange and has produced easily drawing crack, and vertical edge is not straight.
In order to achieve the above object, the technical solution of the utility model is: design a kind of Shells of High Voltage Switches branched hole flanging die device, which comprises at least punch, die, die socket, pull bar forms, it is characterized in that: die shank links together by connector and punch, pull bar top and bottom are processed with respectively external splines, 45 ° of rotations and punch are connected together behind the pull bar top insertion punch inner spline groove, 45 ° of same rotations and master cylinder are connected together behind the pull bar bottom insertion oil cylinder piston inner spline groove, die and die socket are assembled together by the draw-in groove of matched in clearance, right block is used respectively at two ends, left block is fixed die, die socket is fixed on the cross positioning key of main workbench, housing is positioned in place on the die and centering, and punch places on the plug of Mechanical Moving arm front end.
Described die shank is connected with lid by screw, and lid links together with punch.
The crowning of the external splines at described pull bar two ends is to face directly.
The circumferential quartering of external splines at described pull bar two ends, 22.5 ° of each five equilibrium and axial cross center line angles.
The side surface tapering of described punch is 30 degree, and the bottom is the fillet of radius 60mm.
The curved surface of described die 4 is to support cylindrical shell, and its subsequent corrosion R determines according to the barrel diameter size; The curved surface of die 4 and upper surface link into an integrated entity by fillet R30 degree, fillet R90 degree smooth transition.
The utility model characteristics are: the utility model belongs in the flange production process of the cylinder housing branched hole that is mainly used in GIS product aluminium, Steel material, can realize directly cylindrical shell being carried out cold flange in the turn-up process, do not need cylindrical shell is carried out preheating procedure, once realize flanging process, and flange is respond well, without the drawing crack phenomenon, its improvement on the original basis, it improves the pull bar of design again, and No. 45 steel of material selection are from the working strength of material raising pull bar.The external splines of pull bar top end face becomes one deck by original three layers, and such design can guarantee that the spline fitted of pull bar, punch is the face contact all the time, thereby improves the stressing conditions of pull bar in turn-up process.In the situation that does not affect cooperation, the oblique surface machining of former external splines side changed into face processing directly, reduced difficulty of processing.The bad phenomenon such as punch and matrix fillet design specification high conformity contacts with the convex mould surface appropriateness at turn-up process middle cylinder body material, has solved the housing flange and has produced easily drawing crack, and vertical edge is not straight.
