Embodiment
An embodiment of disc insulator cast shaping device of the present invention as shown in Figure 1, for formalizing to the disc insulator 50 of casting forming, this disc insulator 50 comprise middle insert part 51 and have outer turn edge 53 cast 52, this disc insulator cast shaping device comprises the base for supporting 10 of platy structure, be vertically fixed on the intermediate support 20 in the middle part of base for supporting 10, be fixed by screws in the quick-speed jigs support 40 of base for supporting 10 side, be fixed on quick-speed jigs 41 on quick-speed jigs support 40 and for compress support disc insulator 50 outer turn edge 53 annular pressing plate 30.
Wherein the below of base for supporting 10 is fixed with base support leg 12, be convenient to carrying, base for supporting 10 be provided with to turn edge with disc insulator 50 outer 53 step supporting surface corresponding to bottom profile, the part that step supporting surface is corresponding with the datum level 54 turned edge outward on 53 bottom surfaces forms the outer supporting surface 11 that turns edge, for supporting the datum level 54 of disc insulator 50.Middle standing pillar is fixed by screws on base for supporting 10, and its top is provided with the supporting bracket corresponding with the inner face of middle insert part 51 on disc insulator 50, and support plate top surface is configured for supporting surface 55 at the bottom of the basin of medial surface at the bottom of the basin of support disc insulator 50.Supporting surface 11 and the vertical range of supporting surface 55 at the bottom of described basin of turning edge outward equal corresponding disc insulator 50 outer turn edge 53 bottom surface to the design pitch L of medial surface at the bottom of basin, can ensure that design pitch L remains unchanged in the curing process.
There is in the middle part of annular pressing plate 30 centre bore of the side tub wall for dodging disc insulator 50, can overlap and be set on disc insulator 50.The external diameter of annular pressing plate 30 is greater than the external diameter of disc insulator 50, its lower surface has the ring compression face for outer 53 compression fit that turn edge with described disc insulator 50, the part that lower surface top external diameter exceeds disc insulator 50 is provided with guide finger 31 hole, support baseboard is fixed with corresponding guide finger 31, the axis of guide finger 31 is vertical with support baseboard.Insert in guide finger 31 hole for ease of guide finger 31, guide finger 31 top has the boot segment of taper.The compaction direction that guide finger 31 can ensure annular pressing plate 30 is set, can turns edge to disc insulator 50 outer and 53 to compress uniformly, avoid outer turning edge 53 to occur torsional deformation.
Quick-speed jigs 41 adopts fast-holding fixture conventional in prior art, its form has multiple, the compression cantilever 42 of the quick-speed jigs 41 in the present embodiment is provided with elastic hold-down mechanism, elastic hold-down mechanism by being fixed on the spring guide 43 compressed on cantilever 42, the hold-down head 45 that is set in the holddown spring 44 on spring guide 43 and is arranged on holddown spring 44 end forms, can elastic compression be realized, effectively ensure shaping effect.When quick-speed jigs 41 unclamps, annular pressing plate 30 can take off from guide finger 31, is convenient to picking and placeing of disc insulator 50, easy to use.
During use, after disc insulator 50 depanning of having cast, quick-speed jigs 41 is unclamped, take out annular pressing plate 30, disc insulator 50 cast 52 is placed on base for supporting 10, annular pressing plate 30 is led by lead, to be placed on disc insulator 50 and make its ring compression face compress disc insulator 50 outer turn edge 53 top; Then, quick-speed jigs 41 is pressed on plane on annular pressing plate 30, by pressure effect ensure disc insulator 50 water outer turn edge 53 axial two sides not to be distorted distortion.Because intermediate support 20 supports the top of disc insulator 50, top can be avoided to deform, avoid design pitch L to change simultaneously.After disc insulator 50 has solidified, unclamp quick-speed jigs 41, take off annular pressing plate 30, the disc insulator 50 be shaped can be unloaded, in this process, positioner can be good at preventing disc insulator 50 from producing distortion, requirement of ensuring the quality of products, and improves rate of finished products, and adopt the formal operations of quick-speed jigs 41 convenient, operating efficiency is high.
In the above-described embodiments, what base for supporting 10 adopted is platy structure, and hold down gag adopts is annular pressing plate 30 and hydraulic-driven and can realizes the quick-speed jigs 41 of elastic compression.In other embodiments of the invention, base for supporting 10 also can replace with other forms, such as be fixed on the annular base on the corresponding platform arranged, now intermediate support 20 can be fixed to that this platform to realize with base for supporting 10 relative fixing, and hold down gag also can replace with other forms, such as arrange and only adopt many quick-speed jigs 41, rely on quick-speed jigs 41 directly to turn edge to disc insulator 50 outer and 53 to compress.In addition, in above-described embodiment is nonessential structure for forming the guide finger 31 of guiding mechanism, also can save in other embodiments, or replace with other guidance modes, such as pilot hole is set on base for supporting 10, annular pressing plate 30 arranges corresponding lead.Moreover quick-speed jigs 41 also can replace with other forms of the prior art, 53 to be pressed on described base for supporting 10 as long as can realize disc insulator 50 outer to turn edge.
