Abstract
The utility model relates to a plane flattening piece for molding and processing a shielding cover of a filter. The plane flattening piece comprises a planar cover plate, wherein four sidewalls are connected in an integrated manner in the periphery of the planar cover plate, the four sidewalls and the planar cover plate are positioned in the same plane, and every two adjacent sidewalls are connected in an integrated manner via a sector-shaped arch planar portion. The finished shielding cover can be obtained via blanking by a blanking die and molding by a molding die. Thus, the processing procedures are simplified, the material is saved, and the product quality and intensity are ensured.
Description
Technical field
The utility model relates to filter screening cover, refers in particular to filter screening cover processing and forming planar development part.
Background technology
According to national < < 12 planning outline > >, generation information technology is listed in one of seven great strategy new industries in " 12 planning ", is the important directions of following national strategy development.Communications industry as the industry that relates generally in generation information technology, will be supported energetically, be realized the great-leap-forward development of industry in following development.Between the good trend of communications industry development, for the demand of filter, also can be the situation of sustainable growth, wherein the market space of relevant component is huge.
At present, the screening cover of filter generally comprises plane cover plate 1 and is fixed on the sidewall 2 of plane cover plate surrounding, and referring to Fig. 1, surrounding sidewall is by being welded into one, referring to Fig. 2.Its manufacture method is blanking punched for sheet material being carried out by blanking die, makes screening cover planar development part.This planar development part comprises plane cover plate 1 and between 2, four sidewalls 2 of conplane unfashioned sidewall, has gap with plane cover plate 1, and two of a pair of relative sidewall edges leave boss 21 therein.The planar development part of blanking die being made by shaping dies carries out sidewall moulding, by shaping dies, four sidewalls are carried out to bending, then boss 21 is carried out to bending, make it wrap another sidewall, by welding, boss 21 and the sidewall being adjacent are welded on to one again, form screening cover.The planar development part of screening cover, its shape has determined that processing method must comprise four procedures, blanking, moulding, boss bending and welding; Procedure of processing is more loaded down with trivial details, time-consuming, and especially boss bending and welding needs respectively to carry out the bending of four boss and the welding of four corners, while taking a lot of work very much.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of planar development part structure of screening cover, when planar development part is processed as to screening cover, only needs 2 road manufacturing procedures just can machine, time saving and energy saving, saves raw materials for production, has reduced production cost.
For solving the problems of the technologies described above, the technical scheme that the utility model provides is filter screening cover processing and forming planar development part, it comprises plane cover plate, it is characterized in that being connected with four sidewalls in the surrounding of described plane cover plate, described four sidewalls and described plane cover plate same plane, connect by fan-shaped circular arc planar portions one between described adjacent two side.
The radius of described fan-shaped circular arc planar portions is 0.75 times of described sidewall height.
Filter screening cover processing and forming planar development part of the present utility model, it launches part structure by blanking die punch process out-of-plane, then by mould, planar development part is carried out to sidewall drawing and forming, just can obtain screening cover finished product, it is identical with the profile of original screening cover for this screening cover finished product, and, between adjacent wall, be integrated connection.By changing traditional planar development part structure, screening cover processing of the present utility model only needs two operations can complete processing, has saved processing cost.And owing to having avoided sidewall boss and welding, fresh processed screening cover integral body is all formed in one, its shielding action is better, and product quality and intensity are higher.
Accompanying drawing explanation
Fig. 1, existing planar development part structural representation.
Fig. 2, existing screening cover structural representation.
Fig. 3, the planar development figure structure schematic representation of the utility model screening cover.
Fig. 4, the structural representation of the utility model screening cover.
Embodiment
Now lift a preferred embodiment and be specifically described in conjunction with diagram.The planar development part of screening cover of the present utility model, it comprises plane cover plate 3, sidewall 4, sidewall 5, referring to Fig. 3, Fig. 4, wherein.
The processing method of screening cover, first, according to the planar development part design blanking die of screening cover, is designed to mould according to the finished product of screening cover.By blanking die punching press, make the planar development part of screening cover.Then by mould, carry out screening cover moulding, by four rectangular shapes of sidewall bending, now, between adjacent two side, be also directly formed to right angle, because two adjacent walls of planar development part are integrated connection, therefore by after mould moulding, the right angle that two adjacent walls form is integrated connection, has avoided boss bending and the welding sequence of traditional processing.By mould moulding, just directly process screening cover finished product.
Filter screening cover processing and forming planar development part of the present utility model, it is simple in structure, than traditional processing method, has saved twice manufacturing procedure, has avoided the use of sidewall boss, has saved materials'use amount.Processing method is simplified, reduced production cost, improve the quality of screening cover simultaneously.
Claims (2)
