Background technology
The PVC material has obtained increasing application in small-bore electrical casing pipe field.In tubing uses; Its superior performance; Method of testing is more complete, but in toughness detects, also has deficiency, is to have inner spring to support in the middle simulation use to test like crooked test; In low temperature, the inside and outside supporting condition of nothing use and transport, impact the damage that causes bending and distortion but can not simulate tubing fast, can not truly measure the low temperature flexibility of tubing.Cause the deviation and the misunderstanding to product quality understanding of manufacturer and applying unit, cause unnecessary trouble and dispute thus.
The utility model content
To the problems referred to above that exist in the prior art, the purpose of the utility model be to provide a kind of simple in structure, test bending pipes testing apparatus accurately.
Described a kind of bending pipes testing apparatus; Comprise base and be fixedly installed on the protective cover on the base; It is characterized in that being equipped with in the described protective cover pipe fitting detent mechanism that is used for fixing tubing to be measured; Described protective cover top is equipped with web joint, and the cylinder of band piston rod is set on the described web joint, and described pipe fitting detent mechanism comprises following keeper that is connected with base and the last keeper that is connected with the band piston rod.
Described a kind of bending pipes testing apparatus is characterized in that described keeper down comprises following positioning seat that is fixedly installed on the base and the lower sleeve that is articulated and connected with following positioning seat.
Described a kind of bending pipes testing apparatus is characterized in that the described keeper of going up comprises last positioning seat that is fixedly installed on piston rod end and the upper bush that is articulated and connected with last positioning seat.
Described a kind of bending pipes testing apparatus is characterized in that the centre of described web joint is provided with center pit, and piston rod is fixedly connected with last keeper through center pit.
Described a kind of bending pipes testing apparatus is characterized in that described protective cover is an arc-shaped structure.
Above-mentioned a kind of bending pipes testing apparatus; Be used to test the tubing bending property; It comprises base and is fixedly installed on the protective cover on the base that be equipped with the pipe fitting detent mechanism that is used for fixing tubing to be measured in the described protective cover, described protective cover top is equipped with web joint; The cylinder of band piston rod is set on the described web joint, and described pipe fitting detent mechanism comprises following keeper that is connected with base and the last keeper that is connected with the band piston rod.The utility model is inserted in tubing to be measured two ends in the upper and lower sleeve through adopting the said equipment, through cylinder pressed downward upper bush, up to tubing bending to be measured or fracture, measures the quality of pipe performance to be measured.Simple in structure, simple to operate, test accurately is suitable for applying.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is an A-A cross-sectional view among the utility model Fig. 1.
Among the figure: 1-cylinder, 2-piston rod, 3-web joint, 4-protective cover, 5-tubing to be measured, positioning seat under the 6-, 7-base, 8-lower sleeve, 9-upper bush, the last positioning seat of 10-.
Embodiment
Below in conjunction with Figure of description the utility model is done further to describe:
Shown in Fig. 1-2; A kind of bending pipes testing apparatus is used to test the tubing bending property, and it comprises base 7 and is fixedly installed on the protective cover 4 on the base 7; Protective cover 4 is an arc-shaped structure; Be equipped with the pipe fitting detent mechanism that is used for fixing tubing 5 to be measured in it, described pipe fitting detent mechanism comprises following keeper that is connected with base 7 and the last keeper that is connected with piston rod 2, and described keeper down comprises following positioning seat 6 that is fixedly installed on the base 7 and the lower sleeve 8 that is articulated and connected with following positioning seat 6; Lower sleeve 8 can be around positioning seat 6 activities down; Last keeper comprises last positioning seat 10 that is fixedly installed on piston rod 2 terminations and the upper bush 9 that is articulated and connected with last positioning seat 10, and upper bush 9 can be around last positioning seat 10 activities, and protective cover 4 tops are equipped with web joint 3; The cylinder 1 of band piston rod 2 is set on the described web joint 3; The centre of web joint 3 is provided with center pit, and piston rod 2 is fixedly connected with last positioning seat 10 on the last keeper through center pit, and the distance between upper bush 9 and the lower sleeve 8 is less than the length of tubing 5 to be measured.
As shown in the figure, the operating process of the utility model is following: piston rod 2 is slided to the top of cylinder 1, and tubing 5 one ends to be measured are inserted in lower sleeve 8; The other end inserts upper bush 9, because the distance between upper bush 9 and the lower sleeve 8 is less than the length of tubing 5 to be measured, after installation; The pressurized air of stored gas tank under certain air pressure (1.0 ± 0.1 MPa), is opened the pneumatic control valve door; Give cylinder 1 inflation, piston rod 2 is extruded fast moved down, piston rod 2 promotes upper bush 9 and presses down; Tubing to be measured is compressed the generation linear deformation gradually, until bending or fracture, thereby measures the bending property of this tubing to be measured.
