Abstract

The utility model discloses a combined internal profiling model which is composed of a plurality of long bar boards having equal width and different length, wherein, both ends of the boards forms a semicircular shape. The middle of every board is provided with a slotted hole. Both ends of the slotted holes forms the semicircular shape too and is concentric with the semi-circles of the ends of boards. The product can be used for processing the internal holes of ceramic sleeves in different types. The utility model can be used as a pair of internal profiling combined models instead of a thousand-block board type model.

Description

Combined internal profiling modelling for inside and outside profilling base repair machine

The utility model relates to profiling mould in a kind of composite type, is a kind of frock that is mainly used in the processing of high tension electrical porcelain insulator insulator moulding endoporus.

Its interior hole shape of high tension electrical porcelain insulator insulator is generally straight tubular, taper, dolioform.And the endoporus of processing these insulators all adopts the inside and outside profiling trimming machine of interior profiling mould.Used interior profiling mould is made up of according to the model that hole dimension is special in the product of a certain specific insulator one or two.For example Nanjing Dianci Factory adopts this pattern exactly.Use this pattern to make every kind of product need one pair of master plate of corresponding design processing, cause the number of products endoporus to change that then former master plate is scrapped and numerous pattern management, deposit problem such as difficulty.Also may occur in addition bringing the product rejection loss because of receiving mistake.This shows this frock expense material, effort, time-consuming, no versatility is difficult to management.

The purpose of this utility model is exactly the problem at above-mentioned existence, a kind of composite type pattern is proposed, satisfy the different requirements that different insulator endoporus are processed internal profiling mould by its different compound mode, thereby reach the purpose that one pair of pattern can adapt to the processing of various insulator endoporus.

The design's interior profiling combination pattern is to utilize the vertical section broken line of all insulator endoporus all can be subdivided into by some rectilinear(-al)s, only is the length of straight line and the mutual different principle of angle.Profiling mould adopts some width identical in this composite type, the special rectangular plate that length differs, its two ends semicircular in shape, there is a rectangular installation slotted eye centre, the two ends of rectangular slotted eye are semicircular in shape also, and must with the semi-circular concentric at plate two ends.The rectangular plate of some different length is suitably combined, just can be constituted required interior profiling mould.

With reference to the accompanying drawings the utility model is described in detail.

Fig. 1 is an a certain taper insulator endoporus vertical section schematic diagram.

Fig. 2 is the former interior profiling mould schematic diagram that is used for this insulator endoporus processing.

Fig. 3 is the rectangular plate schematic diagram of the utility model monolithic.

Fig. 4 is the interior profiling mould schematic diagram of utility model composite type that is used for this insulator endoporus processing.

Such as Fig. 1, shown in Figure 4, the interior profiling mould of the utility model combined type that is used for this porcelain bushing inner hole processing is made up of three block length batten I, II, III. Their length is respectively greater than each straight line L1, the L2, the L3 that form product endoporus vertical section broken line, and I length is L ' 1, and II is long to be L ' 2, and III is long to be L ' 3. L ' 1〉L1, L ' is 2.〉L2, and L ' 3〉L3. I is with fixing closed assembly ground, II termination, and the center of circle of two plate ends overlaps. Adjust the angle α ' between plate I and the plate II, make α '=α; Plate III termination and plate II also fixedly are stacked, and can slide up and down along the notch of plate II, make L, and " 2=L2 adjusts the angle β ' between plate II and the III, makes β '=β. Like this, the interior profiling mould by I, II, III plate so combine is installed in it on inside and outside profiling trimming machine by the slotted eye on support and the pattern, can satisfy the processing of porcelain bushing inner hole shown in Figure 1.

Because interior profiling combination pattern of the present invention is through appropriate combination, be assembled on the inside and outside profiling trimming machine, thereby process required porcelain bushing inner hole, so, this combined type pattern is adapted to the porcelain bushing inner hole processing of different cultivars, plays the effect of thousand board-like patterns of profiling combination pattern replacement in a pair. In addition, this invention has reduced to produce prepares, and has saved material, and machining period has reduced the labour, is convenient to tool storage room management etc.; And install lightly, adjusts flexiblely, greatly improved the flexibility that equipment is processed, particularly favourable to the product of experimental stage.

Most preferred embodiment, the present invention successfully uses on inside and outside profiling trimming machine that our factory is introduced by West Germany and domestic homemade inside and outside profiling trimming machine, and having produced endoporus already with this composite type pattern is dolioform, taper, straight-cylindrical all kinds of insulators.As: Article Number be＜526501＞the 220KV porcelain shell for current mutual inductor, its L1=312, L2=1252, L3=1140, α=177 ° β=177 °, φ on the insulator aperture=27.3, following φ=405.This product is introduced processing and forming on the inside and outside profiling trimming machine in the West Germany that profiling mould inside and outside the utility model composite type is housed, after testing, and each size conforms drawing requirement of endoporus, and dimensional discrepancy satisfies the GB772-87 standard and company standard is checked standard at goods.Profiling mould has used three blocks of rectangular plates of monolithic as shown in Figure 3 in this composite type, and plate length is respectively 500,1500,1500, and plate is wide by 60, and slotted eye is wide by 9, and thickness of slab 6, material are the A3 steel plate.

Claims

1, profiling mould in a kind of composite type, it is characterized in that profiling mould is according to hole shape in the product in this, adopt some width identical, the rectangular plate that length differs combines, this rectangular plate two ends semicircular in shape, there is a slotted eye centre, and the two ends of slotted eye are semicircular in shape also, and with the semi-circular concentric of plate end.

2, profiling mould in the composite type according to claim 1, the rectangular plate of monolithic of profiling mould in it is characterized in that forming, its length should be respectively greater than each section straight line in the product endoporus vertical section of correspondence.
