Abstract
The utility model discloses ram hammer snubber assembly on a kind of rubber impact elasticity tester, this device comprises cylinder, cylinder one end connects baffle plate, when baffle plate when stretching out state, be positioned at and will carry out above test sample, sample is pressed on fixed head by pressing plate, and cylinder is stretched by connection control device.The utility model structure is simple, be easy to control, easy for installation, efficiently solve ram hammer can again fall to carrying out second time and sometimes hold do not allow it again fall by returning ram hammer that bullet falls from off-gauge At The Height falling impacts and operating personnel with hand, and again return it to the problems of next time impacting at calibrated altitude place.
Description
Technical field
The utility model belongs to rubber materials, is specifically related to ram hammer snubber assembly on a kind of rubber impact elasticity tester.
Background technology
When using Taiwan high ferro impact elasticity tester to measure rubber impact elasticity, by testing standard " the elastic mensuration of GB/T 1681-2009 vulcanized rubber " requirement, start to need to carry out continuous pre-impact more than 3 ~ 7 times as mechanical adjustment to sample, after carrying out mechanical adjustment, with identical speed, three Secondary Shocks are carried out to sample immediately, and write down the resilience reading of three times, their intermediate value is exactly the rebound value of sample, and two samples then calculate their rebound value of arithmetic mean as test sizing.When pre-impact, when ram hammer is after absolute altitude falling impacts sample, because caoutchouc elasticity impulses hammer can return the certain height of bullet (this is also the ultimate principle that impact elasticity measures), if do not stoped, ram hammer can fall to carrying out second time again from off-gauge At The Height falling impacts, after circulation several times like this, hold stopping most, thus affect test findings.When practical operation, operating personnel sometimes hold with hand do not allow it again fall by returning the ram hammer that bullet falls, and again return it to calibrated altitude place and impact next time.Use and seem convenient not.
Summary of the invention
According to the deficiency that prior art exists, provide a kind of structure simple, be easy to control, ram hammer snubber assembly on rubber impact elasticity tester easy for installation.
Technical solutions of the utility model realize by the following method:
Ram hammer snubber assembly on a kind of rubber impact elasticity tester, this device comprises cylinder, described cylinder one end connects baffle plate, when baffle plate when stretching out state, be positioned at and will carry out above test sample, described sample is pressed on fixed head by pressing plate, and described cylinder is stretched by connection control device.
Described baffle plate is respectively provided with a convex body relative to the two ends of pressing plate one side, and be block rubber in the middle of described baffle plate, the centre of described block rubber is concave.
Described control device comprises travel switch and the time relay, and described travel switch connects the ram hammer impacted described baffle plate, and the described time relay connects cylinder by solenoid valve.
The described time relay adopts energization delay relay, and time delay is 2s ~ 3s.
The beneficial effects of the utility model are:
The utility model structure is simple, be easy to control, easy for installation, efficiently solve ram hammer can again fall to carrying out second time and sometimes hold do not allow it again fall by returning ram hammer that bullet falls from off-gauge At The Height falling impacts and operating personnel with hand, and again return it to the problems of next time impacting at calibrated altitude place.

Structural representation when Fig. 2 is the utility model contraction state;
1-baffle plate, 2-cylinder, 3-ram hammer, 4-sample, 5-pressing plate, 6-block rubber, 7-convex body.
Embodiment
Below in conjunction with accompanying drawing, by specific embodiment, technical solutions of the utility model are described further.
As shown in Figure 1 and Figure 2, ram hammer snubber assembly on a kind of rubber impact elasticity tester, this device comprises cylinder 2, cylinder 2 one end connects baffle plate 1, baffle plate 1 is respectively provided with a convex body 7 relative to the two ends of pressing plate 5 one side, and be block rubber 6 in the middle of baffle plate 1, the centre of block rubber 6 is concave.When baffle plate 1 when stretching out state, be positioned at and will carry out above test sample 4, sample 4 is pressed on fixed head by pressing plate 5, and cylinder 2 is stretched by connection control device.Control device comprises travel switch and the time relay, and travel switch connects the ram hammer 3 impacted baffle plate 1, and the time relay connects cylinder 2 by solenoid valve.The time relay adopts energization delay relay, and time delay is 2s ~ 3s.
This device is when normally strong state is in punctured position, as shown in Figure 2, its course of work is after ram hammer 3 impacts sample 4, touch the travel switch such as photoelectricity or magnetoelectricity switch, the time relay is started working, postpone to start after 3s solenoid valve to open cylinder 2 and stretch out baffle plate 1 fast, falling impacts hammer 3 is just buffered again, as shown in Figure 1.When proceeding to impact, when absolute altitude place got back to by ram hammer 3 next time, touch backhaul switch (travel switch such as photoelectricity or magnetoelectricity), cylinder 2 resets, and baffle plate 1 is return, and can carry out lower Secondary Shocks.
The utility model structure is simple, be easy to control, easy for installation, efficiently solve ram hammer 3 can again fall to carrying out second time and sometimes hold do not allow it again fall by returning ram hammer 3 that bullet falls from off-gauge At The Height falling impacts and operating personnel with hand, and again return it to the problems of next time impacting at calibrated altitude place.
