Abstract
The invention discloses an elastic metal sealing ring. The elastic metal sealing ring is composed of a metal circular ring, wherein the section of the metal circular ring is in a spiral shape provided with a cavity at the centre. A manufacturing method for the elastic metal sealing ring comprises the following steps: punching and blanking a metal plate to obtain a circular metal flat plate; then stretching the circular metal flat plate, and cutting off a stretching neck to obtain a cylinder body; then punching a cylinder bottom, and cutting through the cylinder bottom; and finally carrying out curling machining on the cylinder bottom and a cylinder opening respectively to produce a metal circular ring, and configuring the section of the metal circular ring to be in a spiral shape provided with a cavity at the centre. The invention provides an elastic metal sealing ring suitable for the injection moulding industry. The elastic metal sealing ring is convenient to machine and low in manufacturing cost, has elasticity to a certain extent, and can be repeatedly used.
Description
Technical field
The present invention relates to a kind of metal o-ring for flat seal, particularly relate to a kind of for injection moulding
The elastic metal sealing ring in field.
Background technology
When operating ambient temperature is higher than the adaptable temperature of non-metallic seal institute, metal o-ring is as flat
Face static seal is highly effective, is widely used in industrial circle.Mainly there is solid soft metal
Sealing ring, such as red copper sealing ring, and has certain elastic hollow metal O RunddichtringO.Close for red copper
The such solid flexible metal sealing washer of seal, elastic little, pressure once will produce plastic deformation, it is impossible to repeats
Use, the sealing ring that each dismounting all must more renew, and red copper price is higher, adds use cost.
Hollow metal O RunddichtringO is formed by the two ends butt welding of thin-wall seamless pipe circumflexion, has certain bullet
Property, can repeatedly use, but complex process, manufacturing cost are higher.
Summary of the invention
It is an object of the invention to overcome deficiency of the prior art, it is provided that a kind of injection moulding industry that is applicable to
Elastic metal sealing ring and processing method thereof.This elastic metal sealing ring is easy to process, low cost of manufacture,
And there is certain elasticity, can reuse.
The purpose of the present invention is achieved by following technical proposals:
The elastic metal sealing ring of the present invention is a metal ring, has the spiral type of cavity centered by its cross section.
The described spiral number of turns is 1.25 circles～1.5 circles.
In order to make elastic metal sealing ring have certain corrosion resistance, can be by stretchable type cold-rolling stainless steel
Plate is made.
The manufacture method of the elastic metal sealing ring of the present invention is: metal blank is punched out blanking, obtains
One piece of circular metal flat board；Then circular metal flat board is stretched, and cut off stretching eck, obtain one
Individual cylinder body；Again cylinder bottom is punched out, cuts through cylinder bottom；The most respectively cylinder bottom and cylinder mouth are carried out crimping processing,
Make a metal ring so that it is there is centered by cross section the spiral type of cavity.
Wherein, described carries out crimping processing to cylinder bottom and cylinder mouth respectively, and crimping is machined to curled portion for the first time
Dividing and reach 0.75 circle～1 circle, crimping is shaped to a metal ring for the second time, has sky centered by its cross section
The spiral type in chamber.
It addition, the cylinder bottom flare radius of cylinder body that stretching obtains be elastic metal sealing ring diametrically
The half of monolateral thickness.
Described is punched out cylinder bottom, and punching hole diameter is that the outside dimension of elastic metal sealing ring deducts its edge
Diametric monolateral thickness.
Further, first the fillet ring limit along cylinder bottom residual carries out crimping processing to cylinder bottom, is crimped to crimping portion
Reach 0.75 circle～1 circle；Again cylinder mouth is carried out crimping molding.
The sealing principle of the elastic metal sealing ring of the present invention is: be arranged on the elasticity in B plate annular seal groove
Metal o-ring is when by the pressure of A plate, and elastic metal sealing ring occurs elasticity along the hand of spiral in cross section
Texturized so that elastic metal sealing ring remains certain to the bottom of A plate and B plate seal groove
Pressure, stops fluid to overflow outside seal groove.After the pressure of A plate is removed, elastic metal sealing ring recovers former
Shape.
The present invention has the following advantages compared with prior art:
1. the cross section of the elastic metal sealing ring of the present invention is the spiral type of hollow, and this structure improves metal
Planar seal ring is by the elastic performance on pressure direction, thus improves that metal o-ring is repeatable to be made
Number of times, the stability of sealing and reliability.
2. the elastic metal sealing ring of the present invention uses punch machining process, easy to process, reduces and is manufactured into
This, improve productivity ratio.And punch process belongs to cold-working processing, especially produces in drawing process
The phenomenon of raw flow harden so that metal o-ring need not just can be obtained institute by heat treatment process
The intensity needed and hardness.
3. the elastic metal sealing ring of the present invention can use stretchable type cold rolled stainless steel sheet to manufacture, and is normal
Less expensive stainless steel material, reduce material cost.

Detailed description of the invention
Seeing Fig. 1～Fig. 3, the elastic metal sealing ring 1 of the present invention is a metal ring, centered by its cross section
Having the spiral type of cavity, the described spiral number of turns is 1.25 circles～1.5 circles.
In embodiment shown in Fig. 3, the highly elastic metal sealing ring 1 for H is arranged on the annular of B plate 2
In seal groove 21, when A plate 3 presses together with B plate 2, the height of elastic metal sealing ring 1 is pressed
Being condensed to Hc, elastic metal sealing ring 1 occurs elastic Texturized along the hand of spiral in cross section so that elastic gold
Belong to the pressure that sealing ring 1 remains certain to the bottom of A plate 3 and B plate seal groove 21, stop fluid
Overflow outside seal groove 21.After the pressure being applied on A plate 3 and B plate 2 is removed, elastic metal sealing ring
Recover original height H.
Selecting stretchable type cold rolled stainless steel sheet is raw material, and sheet thickness t is the height of elastic metal sealing ring 1
/ 10th of degree H.First plate is punched out blanking, obtains one piece of circular metal flat board 11.The most right
Circular metal flat board 11 stretches, and cuts off stretching eck, obtains a cylinder body 12, outside cylinder body 12
Footpath is identical with the outer diameter D of elastic metal sealing ring 1, and the flare radius r of cylinder bottom 121 is elastic metallic
The half of the diametrically opposite monolateral thickness b of sealing ring 1.Again cylinder bottom 121 is punched out, cuts through cylinder bottom
121, punching hole diameter is that the outside dimension D of elastic metal sealing ring 1 deducts its diametrically opposite monolateral thickness
b.It follows that first the fillet ring limit 123 along cylinder bottom residual carries out crimping processing to cylinder bottom, it is crimped to curling
Part reaches 1 circle；Again cylinder mouth 122 is carried out crimping molding, make a metal ring 1, during its cross section is
The heart has the spiral type of cavity, and the spiral number of turns is 1.25 circles.
Wherein, the outside dimension D of elastic metal sealing ring 1 be its diametrically opposite monolateral thickness b 7～
12 times；The height H of elastic metal sealing ring 1 is 1.04 times of its diametrically opposite monolateral thickness b.
