Description
Technical field
The present invention relates to a kind of automobile-used component of motor vehicle, a kind of especially cylinder seal pad and preparation method thereof.
Background technique
The Chinese utility model patent of existing Patent No. CN201420474877.X entitled " exhaust pipe gasket " a kind of
A kind of exhaust pipe gasket, including the upper and lower are disclosed, the upper layer and lower layer are by the fiber for fiber disposal molding
Plate, is gripped with the middle layer of steel between the upper layer and lower layer, the upper layer, middle layer and lower layer are to be linked together by viscose glue
Overall plate, the convex edge that can improve bend resistance intensity, the entirety are convexly equipped on the bottom surface of the upper and lower layer in top surface on upper layer
It is provided with circular hole compatible with exhaust pipe caliber on plate, anti-friction metal collar is equipped on the inner peripheral surface of circular hole.
The advantages of utility model, is: being not easy to lose, long service life, simple process is easily manufactured, and low production cost meets
Seal request.However, the gasket is easy bending, service life is shorter, therefore the structure of the device also needs to be further improved.
Summary of the invention
The technical problem to be solved by the present invention is to a kind of easy to make, sealing is provided for above-mentioned state of the art
Performance is good and the cylinder seal pad of high production efficiency.
The technical scheme of the invention to solve the technical problem is: this cylinder seal pad, is arranged on gasket
There is the compatible opening of cylinder port, include upper layer, middle layer, lower layer on the gasket, the middle layer is folded in upper layer under
Layer between, it is characterised in that: be provided on the top surface and bottom surface of the gasket be disposably extruded from can improve leakproofness
The convex ribs of bend resistance intensity can be improved again.
As an improvement, be made of respectively two points of convex ribs in top surface with the convex ribs on bottom surface, two points of convex ribs are by setting
Meter requires to be convexly equipped on the top surface and bottom surface of gasket in the form locally separated with corresponding positions that is close together, and described two points
Convex ribs it is of same size, every width for dividing convex ribs is 1.0~1.5mm, divides convex ribs from a surface to convex ribs on top surface or bottom surface
The height of top surface is 0.03~0.06mm.The structure of this design not only saves material, but also can rightly play sealing
It is required that dividing the width of convex ribs excessive such as every, then material is wasted, and too small that sealing can be made to imitate is bad；And on top surface or bottom surface
Divide convex ribs from a surface to convex tendon top surface height be 0.03~0.06mm, when gasket pad being made to be placed in cylinder, it can play
Replacement is more convenient, while can play good extruding tightness again, very ideal through practical effect.
It is further improved, the upper layer is graphite linings, and the middle layer is metal plate layer, and the lower layer is coating, the stone
Layer of ink and middle layer are bonded together by glue, and the lower layer is to apply to stick on the bottom surface in middle layer.
Be further improved, the upper thickness be 0.8~1.2mm, the middle layer with a thickness of 0.2~0.4mm, under described
Layer is with a thickness of 0.1~0.3mm.
As an improvement, being painted with skin of paint respectively on the top surface of the gasket and the surface of bottom surface.
As an improvement, being equipped with anti-friction metal collar on the inner peripheral surface of the opening.
It is further improved, top surface and gold is respectively equipped on the upper and lower surfaces on the local outer periphery of the metal collar
Belong to the reinforcement annular bar of lantern ring top flush, the width for reinforcing annular bar is 2~4mm.
As an improvement, the opening of the gasket is four, the quantity and opening of the metal collar are corresponding and described
Metal collar is coated on the periphery of opening for entirety lantern ring made of time processing, and the depth that the metal collar is packed in is
2~6mm.
As an improvement, being provided with fixed hole in the overall structure, being equipped in the fixed hole can be convenient for changing
Sheet metal, be provided with fixation hole on the sheet metal, the sheet metal with a thickness of 0.08~0.3mm.
The production method of the cylinder seal pad, by following steps:
One, first the graphite linings of the specific thickness on upper layer are adhered on the surface in middle layer by glue, lower layer is applied and is placed in
On the bottom surface in middle layer, and control the thickness of lower layer；
Two, again by upper layer, middle layer, under be placed in extrusion die and carry out extrusion forming；
Three, the gasket of extrusion forming is subjected to deburring, as sealing element molded product；
Four, metal collar bound edge is carried out again；
Five, it brushes and paints on sealing element molded product, be finished product after airing.
Compared with the prior art, the advantages of the present invention are as follows: disposable extruding is provided on the top surface and bottom surface of gasket
Made of convex ribs, sealing performance can not only be improved and improve bend resistance intensity, and production efficiency is significantly had submitted, make to produce
Efficiency improves at least three times or more than original production efficiency, to greatly reduce labor intensity, is effectively saved production expense
With, and the convex ribs by being once extruded from have sealing station more acurrate, have set because having in extrusion die,
It is more preferable to produce gasket leakage efficiency, the service life is longer to make gasket；In addition, cylinder seal is lined with three layers, on
It is respectively equipped with the reinforcement annular bar of top surface Yu metal collar top flush on layer and lower layer, improves cylinder seal and pads bend resistance energy
Power；Be equipped with anti-friction metal collar on the inner peripheral surface of opening, extend the service life of cylinder seal pad, sealing effect into
One step improves, and the depth that metal collar is packed in is 2~6mm, makes metal collar be not easy to loosen, further increases sealing performance；Gu
Determine to be provided with sheet metal on through-hole, replacement is convenient.And the production method in the present invention is very convenient, production quality is stable and easy
Operation.
