Abstract
Provided is a slot resonance column. The resonance column is in a barrel shape, and comprises a bottom part and a hollow cylindrical part. A circumferential wall of the hollow cylindrical part is provided with four equal slots, and the slots are vertical to the bottom part.
Description
Technical field
The utility model relates to communications industry, refers in particular to the resonant column that communications industry is used.
Background technology
In communications industry, conventionally all can use resonant column.Resonant column is one of key element forming cavity body filter.The principle producing according to cavity body filter, the metallic cavity of resonant column and sealing produces resonance frequency, thereby realizes the required frequency of cavity body filter.
Conventionally, resonant column is all that whole block material is through machine work moulding.Utilize lathe to go to make it to form the required shape of resonant column in the car of unnecessary material, comprise that body forms resonant column with the flange being connected with body.Existing resonant column is owing to utilizing whole block material car out, and therefore the utilance of its material is very low, and the waste causing is very large.Or with sheet material carry out punching stretch form resonant column.Punching stretch causes the strength of materials to reduce.A filter needs multiple resonant columns, and therefore, the cost that this traditional diamond-making technique of resonant column causes has accounted for the very large ratio of filter.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of resonant column of new structure and makes the compacting tool set of this resonant column.This resonance pole structure is simple, easy to make, the phenomenon such as the fracture that can avoid original plate stamping to stretch causing by the compacting tool set of peculiar exploitation, wall unevenness.
For the above-mentioned technical problem that needs solution, the technical scheme that the utility model provides is a kind of plane-of-weakness joint type resonant column, and it is barrel-shaped, comprise bottom and hollow cylindrical portion, it is characterized in that, on the perisporium of described cylindrical portion, offering four impartial lines of rabbet joint, the described line of rabbet joint and described bottom vertical.
The width of the described line of rabbet joint is 0.5mm..
The compacting tool set of plane-of-weakness joint type resonant column, it is characterized in that comprising blanking die, Bending Mould and mould, wherein, described blanking die comprises staking punch, described staking punch profile is mated with the profile of cross blanking, described cross blanking comprises the circular piece with centre bore, at the edge of described circular piece with cross sheet; Described Bending Mould comprises formpiston and former, described former has the groove mating with described cross blanking, the groove mating with the cross sheet of described cross blanking is arc shape groove, and described formpiston is that the cross matching with described cross blanking that has matching with described former protrudes pressing portion; Described mould comprises the former that just has the cylindrical hole that together the circular piece profile of described cross blanking matches, and with the formpiston of the punching press post mating with described cylindrical hole.
Resonant column provided by the utility model and process the compacting tool set of this resonant column, by blanking die, prepare cross blanking, then through Bending Mould, the cross sheet of cross blanking is carried out to bending, its four cross sheets are combined can form cylindrical, then by mould, carry out moulding, the cross sheet that makes cross blanking is combined into cylindrical with the line of rabbet joint perpendicular to circular piece, forms resonant column finished product.By mould of the present utility model, changed the problems such as fracture that the direct punching stretch of original sheet material occurs, wall unevenness, guaranteed material and the structural quality of resonant column.And, novel plane-of-weakness joint type resonant column, its resonance effect is good.

Embodiment
For technique scheme, now lift a preferred embodiment and be specifically described in conjunction with diagram.Referring to Fig. 1 ~ Fig. 5.Resonant column provided by the utility model and process the compacting tool set of this resonant column, by blanking die, prepare cross blanking, then through Bending Mould, the cross sheet of cross blanking is carried out to bending, its four cross sheets are combined can form cylindrical, then by mould, carry out moulding, the cross sheet that makes cross blanking is combined into cylindrical with the line of rabbet joint perpendicular to circular piece, forms resonant column finished product.Wherein.
Blanking die, comprises the staking punch 21 mating with cross blanking shape, by staking punch punching press, forms cross blanking, for further bending and molding is prepared.
Bending Mould, comprises formpiston 31 and former 32.On the stitching surface of former 32, offer the cross arc groove 33 that same cross blanking profile matches.The centre of converging at cross groove 33 is circular groove, and its profile is mated with the circular piece profile of cross blanking.Corresponding former 32 on formpiston 31 offers with the cross arc groove of former and wants the cross arc fin 34 mating on its stitching surface.In order to guarantee when Bending Mould carries out bending to cross blanking, circular piece to cross blanking causes extruding, in the corresponding cross blanking of formpiston and former position, be all correspondingly provided with the circular groove of depression, so mould structure, guarantee when bending, only cross sheet is carried out to radian bending, and can not cause extruding to circular piece.
Mould, comprises former 41 and formpiston 42, offers the cylindrical hole 43 of an opening on former 41, and the external diameter of the circular piece of the shape of this cylindrical hole 43 and cross blanking matches; On formpiston 42, offer punching press post 44, the cylindrical hole on profile and the former of this punching press post matches.When carrying out moulding, the circular piece that punching press post props up the cross blanking that carried out bending makes in its cylindrical hole that enters former, and the cross sheet of the bending of cross blanking, under punching press post and cylindrical hole effect, draws in and forms barrel-shaped resonant column.In the cylindrical periphery wall of the resonant column of overmolding, be evenly distributed with four lines of rabbet joint, the seam of every line of rabbet joint is wide is 0.5mm left and right, and its bottom is the circular piece of cross blanking.
By blanking die, Bending Mould and mould, the novel barrel-shaped resonant column 5 with even four lines of rabbet joint is just easily made in the situation that there is no material extending, its manufacture craft is simple, fracture, the even bad phenomenon of resonant column wall unevenness of having avoided material extending to cause, improve product quality, guaranteed the consistency of product quality.
Claims (2)
1. a plane-of-weakness joint type resonant column, it is barrel-shaped, comprises bottom and hollow cylindrical portion, it is characterized in that, on the perisporium of described cylindrical portion, offering four impartial lines of rabbet joint, the described line of rabbet joint and described bottom vertical.
2. plane-of-weakness joint type resonant column according to claim 1, the width that it is characterized in that the described line of rabbet joint is 0.5mm.
