Below in conjunction with the embodiment that attached drawing 1 to 14 provides, the plastic tube impact strength of the utility model is further illustrated
Inspection equipment specific implementation mode.The inspection equipment of the plastic tube impact strength of the utility model is not limited to following implementation
The description of example.
As shown in Figure 1, the inspection equipment of the plastic tube impact strength of the utility model, including it is used for fixed plastics pipe fitting
Fixing device 200 and with fixing device 200 be oppositely arranged for impacting the percussion mechanism of plastic pipe, fixing device 200
It is arranged on pedestal 110, percussion mechanism is connect with the rack 120 on pedestal 110 to be arranged in the top of fixing device 200, impact
Device includes actuating unit 400 and the impact probe being connect with actuating unit 400 300, and actuating unit 400 drives impact to visit
Cylinder may be used in the inner wall of first 300 impact plastic pipe, actuating unit 400, and the mobile power and speed of impact probe 300 can
Quantified controlling is carried out by cylinder parameters (position, air pressure and stroke), according to the practical set and service condition of different product,
Provide that the concrete numerical value of cylinder parameters, certain actuating unit 400 can also use hydraulic cylinder or motor etc. in test stone.

Force analysis figure of the plastic pipe when being impacted as shown in Figure 2, gos deep into impact probe 300 in plastic pipe
It during portion, is equivalent between impact probe 300 and plastic pipe and forms interference fit, impact probe 300 can be to modeling
The inner wall of expects pipe part generates extruding force, the longitudinal stress σ of plastic pipeLWith circumference stress σθIt can squeezing according to plastic pipe inner wall
The wall thickness S of pressure P, the average diameter D of plastic pipe and plastic pipe are found out：
σL=PD/4S；
σθ=PD/2S；
From the above equation, we can see that the circumference stress σ of plastic pipeθMuch larger than longitudinal stress σL, therefore consider fracture failure when
It waits, longitudinal stress σ can be ignoredLOnly consider circumferential tolerance, circumference stress, which is equal to after plastic pipe perimeter stretches, to be generated
Stress, the elongation strain ε of the perimeter of plastic pipe can be according to the outer diameter D o of the impact probe 300 and internal diameter Di of plastic pipe
Find out (Di<Do)：
ε=(Do-Di)/Di；
In order to reach best test effect, it should be ensured that the elongation strain ε of the perimeter of plastic pipe is less than plastics material used
The breaking strain ε of matter itselfB, by ε<εBAbove formula is substituted into obtain：
Do<Di(1+εB)；
The outer diameter D o for adjusting impact probe 300 when inspection by telescoping mechanism makes the outer diameter D o of impact probe 300 meet
Di<Do<Di(1+εB), most accurate, reliable test effect can be reached.
