Abstract
The utility model discloses a large-R circular arc bending tool for paper boards, which consists of two parts including a controlling plate and a circular arc plate. The two parts are a connected entirety; the circular arc plate is arranged at one side of the lower end of the controlling plate; and a vertical slot in which the paper board can be inserted is arranged on the controlling plate. The large-R circular arc bending tool for the paper boards is convenient and quick to operate, has high efficiency, and does not occupy production field.
Description
Technical field
The utility model relates to a kind of power tool, is specifically related to the big R circular arc of a kind of cardboard bending tool, is suitable for large oil immersed high voltage transformer insulating part manufacturing, and insulating board bending R circular arc is greater than 15mm.
Background technology
My company is when developing large-scale ultrahigh pressure oil immersed type reactor, iron core side pole has adopted outsourcing multilayer screen structure, other post is a rectangular column, each layer screen is 2.0 thick single piece of cardboard, being converted into U-shaped places three faces of whole other post, the bending place of U-shaped screen is the R circular arc, and R value layer from inside to outside increases successively, all screen bending places are that the R circular arc is all greater than 15mm, the cardboard bending need be adopted folding brake, and during but R＞15mm, flanging equipment can not be realized processing, therefore, the big R circular arc of essential a kind of cardboard of development bending tool.
Summary of the invention:
Technical problem to be solved in the utility model is: solve the problem that above-mentioned prior art exists, and provide a kind of make the specification requirement simple, that expense is few, the bending product can satisfy drawing and convenient to operation, efficient is high, do not take the big R circular arc of the cardboard bending tool of production site.
The technical solution adopted in the utility model is: the big R circular arc of this cardboard bending tool is by controlling plate and circular arc plate two parts constitute, two parts are whole for connecting, the circular arc plate is positioned at controls plate lower end one side, controls and has the vertical slot that can insert cardboard on the plate.
In the technique scheme, the big R circular arc of this cardboard bending tool adopts the machine-shaping of pressed laminated wood material, and its thickness is 60～80mm, and the vertical slot height is advisable less than 400mm, and the vertical slot width is 2.5～3mm, and the R value of circular arc plate is by being determined by the cardboard arc chord angle of bending.
Beneficial effect:
Bending tool of the present utility model can be made by oneself, and makes simply, and expense is few, and the bending product can satisfy the specification requirement of drawing, and convenient to operation, and the efficient height does not take production site, has solved the tool equipment problem of the big R circular arc of insulating board bending.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model fundamental diagram.
The specific embodiment:
Referring to Fig. 1, the big R circular arc of this cardboard of the present utility model bending tool, by controlling plate 1 and circular arc plate 2 two parts constitute, two parts are whole for connecting, and circular arc plate 2 is positioned at controls plate 1 lower end one side, controls and has the vertical slot 4 that can insert cardboard 3 on the plate.The utility model adopts the machine-shaping of pressed laminated wood material, and its thickness is 60～80mm, and the vertical slot height is advisable less than 400mm, and the vertical slot width is 2.5～3mm, and the R value of circular arc plate is by being determined by the cardboard arc chord angle of bending.
Referring to the operation principle of Fig. 2, the edge of vertical slot 4 from cardboard 3 inserted, the R nose circle of circular arc plate 2 is pressed on the position of cardboard 3 need bendings, if cardboard is very long, need to adopt a plurality of bending tools to carry out simultaneously.The upper end of controlling plate 1 with holds and up turn over, make cardboard 3 be bent to 90 degree, extract vertical slot 4 then out, by the another side of cardboard 3 being bent to 90 degree, extract vertical slot 4 out again,, make it keep shape, can finalize the design behind the natural airing with the interim colligation of cotton yarn tape with quadrat method.
Claims (2)
1. the big R circular arc of cardboard bending tool is characterized in that: by controlling plate and circular arc plate two parts constitute, two parts are whole for connecting, and the circular arc plate is positioned at controls plate lower end one side, controls and has the vertical slot that can insert cardboard on the plate.
2. the big R circular arc of cardboard according to claim 1 bending tool, it is characterized in that: bending tool adopts the machine-shaping of pressed laminated wood material, its thickness is 60～80mm, the vertical slot height is advisable less than 400mm, the vertical slot width is 2.5～3mm, and the R value of circular arc plate is by being determined by the cardboard arc chord angle of bending.
