Description
Technical field
The utility model belongs to machinery industry frock clamp field more particularly to pipe fitting total cross-section tension test.
Background technology
For DN≤50mm steel pipes, the full cross section sample of generally use, but difficulty is sampled, processing capacity is big and time-consuming.Pipe
The conventional method of clamping of part, which is divided into, flattens clamping and the clamping of steel duct plug, wherein it is past to flatten the yield strength for being clamped and measuring and
It is very big toward error；It is clamped using plug, plug is not easily taken out a large amount of wastes for causing material after pipe fitting stress, often does primary experiment
It is required for remaking plug, and processes plug and take time and effort.
Invention content
We will solve the problems, such as：A kind of full cross section tension test tooling is designed, there is reusing, overcome
The a large amount of of material waste and take time and effort so that experiment becomes simple and reliable, and the accuracy of guarantee test data.
Technical solution is：
Pipe fitting total cross-section tension test tooling, structure include casing 1, cone stick 2, removal rod 3, dumbbell shaped handle 4；Institute
1 outer diameter of casing stated is slightly less than pipe fitting internal diameter, is divided into pintongs, and casing 1 can divide valve to be packed into pipe fitting, and there are baffle ring, baffle ring in 1 one end of casing
Outer diameter is equal to or slightly less than tube outer diameter；The small end of the cone stick 2 is slightly less than 1 internal diameter of casing, and big end is slightly larger than in casing 1
There is a threaded hole at diameter, length >=100mm, 2 big end center of cone stick；The removal rod 3 is screw structure, and one end is equipped with screw thread,
Screw thread can be matched with the 2 big end screwed hole of centre of cone stick；4 internal diameter of dumbbell shaped handle is slightly larger than 3 middle part of removal rod
Outer diameter, can be flexibly mobile at 3 middle part of removal rod.
All of above structure material is 20# steel or Q235B.
The tension test of pipe fitting total cross-section is as follows with tooling application method：
1. making full cross section sample by GB/T 2975, gauge length is got on sample with metal marking machine；
2. casing 1 and cone stick 2 are packed into 5 both ends of tensile sample pipe fitting respectively；
3. lower collet first by test specimen clamping in upper grip, then is moved to suitable clip position, finally by clamping test specimen
Clamp test specimen lower end；
4. starting testing machine, slowly equably load, until test specimen is pulled off, removes tensile sample；
5. removal rod 3 connect and tightens with cone stick 2, one hand dumbbell shaped handle 4 of holding with a firm grip firmly hammers backward, makes dumbbell shaped handle
4 bump against with 3 rear end of removal rod, extract cone stick 2 under the action of impact force, dismantle casing 1, back out removal rod 3；
6. the casing of the sample pipe fitting other end and cone stick is split out with same procedure, back out removal rod 3；
7. recording test data.
The utility model has the following advantages compared with the tubing total cross-section tension test prior art：
1, the error for avoiding the test data caused by tubing is pinched ensure that the accuracy of test data.
2, repeat and utilize, the not equal pipe fitting of but wall thickness identical for tubing nominal diameter only need to make a secondary casing 1 and
Stick 2 is bored, lot of materials and processing charges are saved.
3, simple in structure, manufacturing cost is low so that experiment becomes simple and reliable, improves test efficiency.
