Fig. 1 is rubber pad, round steel, steel seat and pressure in the rubber pad rubber adhesive strength test method of specific implementation mode
The assembly structure figure of testing machine.
Fig. 2 is the distribution map on the upper pressure hole that rubber pad opens up and pushing mono- circumference of Kong Yuan.
Specific implementation mode
It 1 to Fig. 2 elaborates below in conjunction with the accompanying drawings to the embodiment of the present invention.
Rubber pad rubber adhesive strength test method selects round rubber pad or polygon rubber pad to be tested, rubber
Each layer metallic plate and the bond area of rubber layer are equal in pad, and rubber pad is horizontally disposed with, with vertical force-extension adjacent two
Rubber layer between layer metallic plate, until rubber layer is detached from metallic plate, it is vertical outer when metallic plate is detached from rubber layer
Power F and when test metallic plate and rubber layer bond area S, calculating the ratio of F and S, to be worth to rubber layer bonding with metallic plate
Intensity P, it is characterised in that the adjacent two layers metallic plate is respectively upper layer metallic plate 100 and lower metal plate 101, described
Rubber pad on open up and be vertically staggered and upper pressure hole 1 that diameter is equal and push hole 2, the upper pressure hole 1 is from rubber pad
Top surface is opened up across upper layer metallic plate 100 to the top surface of lower metal plate 101, and the pushing hole 2 is opened from the bottom surface of rubber pad
If across lower metal plate 101 to the bottom surface of upper layer metallic plate 100, it is inserted into round steel 3 in upper pressure hole 1 and pushing hole 2, vertical
Make that the round steel 3 in hole 1 is pressed to move downward under the action of external force, upper layer metallic plate 100 and lower metal plate 101 apart from increase,
The rubber layer 102 between upper layer metallic plate 100 and lower metal plate 101 is stretched, until upper layer metallic plate 100 and/or lower layer's gold
Belong to plate 101 and rubber layer 102 and detaches.
Above-described rubber pad rubber adhesive strength test method, according to the design feature of rubber pad, on rubber pad
Open up the upper pressure hole 1 that is vertically staggered and push hole 2, upper pressure hole 1 from the top surface of rubber pad open up across upper layer metallic plate 100 to
The top surface of lower metal plate 101 pushes hole 2 and is opened up from the bottom surface of rubber pad across lower metal plate 101 to upper layer metallic plate 100
Bottom surface, and vertical force is applied to upper layer metallic plate 100 and lower metal plate 101 by round steel 3, makes 100 He of upper layer metallic plate
Lower metal plate 101 pulls open, until being detached from rubber layer 102.It should be noted that different with 2 quantity of hole is pushed in upper pressure hole 1
When, upper layer metallic plate 100 and lower metal 101 may be caused not to be detached from rubber layer 102 simultaneously, when upper layer metallic plate 100 with
One of them is detached from lower metallic plate 101 with rubber layer 102, just records vertical external force F when metallic plate is detached from rubber layer, you can
Calculate the adhesive strength of the metallic plate and rubber layer that are detached from rubber layer.
By multiple repetition test, the sum of the hole area in upper pressure hole 1 and the sum of the hole area for pushing hole 2 are not less than metal
The 1/15 of plate and the bond area of rubber layer, it is ensured that metallic plate under the promotion of round steel, can be effectively detached from rubber layer, and circle
Steel 3 moves downward that stroke is moderate, avoids the damage of round steel 3 in test process.
Wherein, the upper pressure hole 1 is equal with the quantity in hole 2 is pushed, and upper pressure hole 1 and pushing hole 2 are equal on the same circumference
Even isolation is distributed, and between two adjacent upper pressure holes 1 one pushing hole 2 of distribution, as can be seen from Figure 2 upper pressure hole 1 and pushing
The quantity in hole 2 is four, and is evenly distributed on same circumference, ensure upper layer metallic plate 100 and lower metal plate 101 by
Power is uniform, and upper pressure hole 1 is equal with 2 quantity of hole is pushed, and upper layer metallic plate 100 and lower metal plate 101 can be made same with rubber layer 102
When be detached from.
Wherein, it is bonding with rubber layer to account for metallic plate for the area of the circumference in the upper pressure hole 1 and pushing hole 2 distribution place
The 1/3 ~ 1/2 of area, as shown in Figure 2, the area of inner ring A are the area of the circumference where upper pressure hole 1 and the distribution of pushing hole 2,
The area of outer ring B is the bond area of metallic plate and rubber layer, i.e. the area of inner ring A accounts for the 1/3 ~ 1/2 of the area of outer ring B, is protected
Demonstrate,prove metallic plate plane uniform force Nian Jie with rubber layer, metallic plate is essentially whole face disengaging, raising survey with rubber layer when disengaging
The operability of method for testing.
Specifically, a diameter of 16 ~ 24mm in upper pressure hole 1, quantity are 4 ~ 8, upper layer metallic plate 100 and lower metal plate
101 have enough forced areas, and metallic plate is made to be detached from rubber layer, and upper pressure hole 1 and the size sum number for pushing hole 2
Metallic plate and the bond area of rubber layer are too small when amount will not cause to test, to ensure the adhesive strength tested out in error model
In enclosing.
In actual test, the length of round steel 3 is too short, can lead to press the round steel 3 in hole and push the round steel in hole 2
3, which collide with each other, causes to damage, long, can improve space requirement when difficulty of test and test, therefore the length of the round steel 3
It is 3 ~ 4 times of rubber mat thickness, can effectively avoid round steel 3 in test process and more collsion damages, one end of round steel 3 and upper pressure occurs
Hole 1 pushes 2 clearance fit of hole, facilitates the placement of round steel 3.
Wherein, the round steel 3 being placed in pressure hole 1 is connected by steel seat 4 forms entirety, is placed in and pushes in hole 2
Round steel 3 is connected also by steel seat 4 forms entirety, and the steel seat 4 is horizontally disposed parallel with rubber pad, and the steel seat 4 is fixed
In the other end of round steel 3, vertical force, which acts on, makes that the round steel 3 in hole 1 is pressed to move downward on steel seat 4, and steel seat 4 is by 3 side of round steel
Even whole, vertical force acts on steel seat 4, makes to press the stress synchronous with the round steel 3 pushed in hole 2 of hole 1, is further ensured that metal
The uniform force of plate.
As shown in Figure 1, providing the vertical force acted on steel seat 4, rubber pad setting by pressure testing machine 200
In on pressure testing machine 200, the steel seat 4 of 3 end of round steel in upper pressure hole 1 is contacted with the pressure head of pressure testing machine, is pushed in hole 2
The steel seat 4 of 3 end of round steel contacted with the chassis of pressure testing machine, Opening pressure testing machine, pressure head moves downward, pressure effect
Move downward the round steel 3 in upper pressure hole 1 on steel seat 4, upper layer metallic plate 100 and lower metal plate 101 are apart from increase, when upper
When layer metallic plate 100 and lower metal plate 101 and rubber layer 102 are with being detached from, the load reading of pressure testing machine be metallic plate with
Vertical external force F when rubber layer is detached from.When pressure testing machine is opened, the speed control that pressure head moves downward is in 10 ~ 20mm/
Min, when tester being facilitated accurately to read upper layer metallic plate 100 and lower metal plate 101 with rubber layer 102 and disengaging, pressure
The load of testing machine is read.
