Abstract
The invention provides a silicone rubber sealed mini electrical box which comprises a box body, wherein installation legs are arranged at the bottom of the box body, the box body is connected with a box cover via hinges, the box body and the box cover are sealed by a silicone rubber sealing strip, an upper edge of a box opening of the box body is inwards bent and contact the inner wall of the box body, an arc is formed at a bent position, and the arc part and the silicone rubber sealing strip are in interference fit. The invention also provides a fabrication method for the silicone rubber sealed mini electrical box. The whole box opening is bent, flattened and formed at one time by a dual-bending and flattening technique, and the edge of the box opening is reserved during flattening so as to ensure the arc formed at the edge. By bending, flattening and forming the box opening at one time, the processing difficulty is greatly reduced; and since the box opening with the arc is flattened and formed, the rigidity of the box opening is increased, an arc surface is very easy to be pressed into the silicone rubber sealing strip, moreover, the sealing effect is high, and the silicone rubber sealing strip cannot be cut and broken.
Description
Technical field
The present invention relates in a kind of power supply industry electrical assemblies switchgear equipment little three casees used, particularly relate to a kind of little three casees being undertaken sealing by silastic sealing strip.
Background technology
Electrically mainly comprise headstock, lighting case, batch meter etc. little three casees.Control cabinet, socket box belong to headstock classification, and user kit belongs to lighting case classification, and ammeter box belongs to batch meter classification.This kind of nonstandard all small box are all referred to as little three casees.
At present, require in the product of little three casees of high switchgear assembly in useful life, usually adopt silicon rubber to make seal, as shown in Figure 1, casing 1 is connected with case lid 4 by hinge 2, is sealed between casing 1 and case lid 4 by silastic sealing strip 3.Silicon rubber has feature that is high temperature resistant, long service life, but silastic sealing strip is close relative to its material of sealing strip of other materials and hard, therefore, the case mouth of band gradient made by usual casing 1, be convenient to the insertion silastic sealing strip 3 that case mouth edge can be more deep, play sealing effectiveness effectively.But this structure defect specific as follows:
1) the case oral area indent of casing forms the case mouth of band gradient, and it is complicated that this structure adds man-hour processing step, needs special equipment and special grinding apparatus, and cost is higher and waste time and energy;
2) silastic sealing strip directly inserts from the edge of case oralia material, and the corner angle that case oralia material is sharp easily cut silastic sealing strip.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind ofly processes convenient welding, good sealing effect and can not cut little three casees of silastic sealing strip.
In order to solve the problems of the technologies described above, technical scheme of the present invention is to provide little three casees of a kind of silicone rubber seal, comprise casing, bottom half is provided with installation foot, casing is connected with case lid by hinge, is sealed between casing and case lid by silastic sealing strip, it is characterized in that: the case mouth of described casing is fitted along inside bending with cabinet wall, bending part forms circular arc, and circular arc place and described silastic sealing strip are crossed to win and coordinated.
Preferably, along being square waveform on the case mouth of described casing, after bending, square waveform place and cabinet wall are fitted.
Present invention also offers the manufacture method of little three casees of a kind of silicone rubber seal, it is characterized in that, step is:
The first step: get one block of plate, carry out the four sides side plate of casing and the planning of case oralia material onboard, case oralia material is positioned at the top of respective side plate;
Second step: the bending part between side plate and case oralia material, under the state forming straight line, carries out Integral bending flattening, will guarantee that bending part forms circular arc during flattening;
3rd step: carry out 90 degree of bendings along the bending part between adjacent side plates, forms a casing casing only having a limit not close;
4th step: the open side weld of casing casing is connect, and bottom casing casing, add the welding of block base plate, form casing;
5th step: make case lid, install hinge, and paste silastic sealing strip between casing and case lid inside case lid, when case lid is closed, silastic sealing strip just in time props up the circular arc place of case mouth and interference fit.
Preferably, before described case mouth sheet metal bending, along going out breach on case oralia material, form square wave-shaped configuration; After bending, square waveform place and side plate inwall are fitted.
Device case mouth provided by the invention flattens technology processing by double-bending, and the bending of whole case mouth is flattened shaping.During flattening, case mouth edge reserves, and guarantees that edge forms circular arc.A bending is flattened shaping case mouth difficulty of processing and is greatly reduced, and band circular arc flattens shaping case mouth, not only adds the rigidity of case mouth, and arc surface is also easily pressed into silastic sealing strip and good sealing effect, also can not cut silastic sealing strip.

Embodiment
For making the present invention become apparent, hereby with a preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
Fig. 2 is the little three casees cutaway views of silicone rubber seal provided by the invention, described silicone rubber seal is little comprises casing 1 for three casees, installation foot 7 is housed bottom casing 1, casing 1 is connected with case lid 4 by hinge 2, sealed by silastic sealing strip 3 between casing 1 and case lid 4, casing 1 and case lid 4 are also locked by clamping screw 5 and locking nut 6.Composition graphs 3, the case mouth of casing 1 is fitted along inside bending with cabinet wall, and bending part forms circular arc.
Composition graphs 4, the case mouth of casing 1 flattens technology processing by double-bending, and the bending of whole case mouth is flattened shaping.During flattening, case mouth edge reserves, and guarantees that edge forms circular arc.A bending is flattened shaping case mouth difficulty of processing and is greatly reduced, and band circular arc flattens shaping case mouth, not only adds the rigidity of case mouth, and arc surface is also easily pressed into silastic sealing strip 3 and good sealing effect, also can not cut silastic sealing strip.
Composition graphs 5 and Fig. 6, edge on the case mouth of casing 1 is designed to square waveform, and after bending, square waveform place and cabinet wall are fitted, and square wave-shaped configuration contributes to realizing a bending better and flattens shaping, makes on case mouth along fitting tightr with cabinet wall.
Add man-hour, the four sides side plate of casing 1 is on one block of plate, and the case mouth of flattening is on the top of respective side plate.First, along going out breach on the case mouth of casing, form square wave-shaped configuration, then along the case mouth bending part of whole casing under shape is into a straight condition, carry out Integral bending flattening, during flattening, case mouth edge reserves, and guarantees that edge forms circular arc.Then, 90 degree of bendings are carried out to casing, make it form a casing casing only having a limit not link up.During welding processing, as long as the splice point both sides alignment of guard box mouth, just can realize the smooth welding of case mouth.As long as bottom half adds in the welding of block base plate, whole casing just welding completes.Silastic sealing strip 3 is pasted onto on case lid 4, as long as to control the degree of depth of case mouth press-in silastic sealing strip well just passable in the welding of hinge 2, processing welding is simple and convenient.
The little three-bin system of the silicone rubber seal of flattening shaping box mouth provided by the invention is done simple, and without the need to special equipment and special grinding apparatus, processing technology is good, can accomplish that volume is enough little, is applicable to the degree of protection such as nuclear power, explosion-proof, EME and requires that high occasion uses.
