Change foundation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the weld seam stretching bending experiment instrument that the embodiment of the present invention provides.
Detailed description of the invention
In order to understand the present invention in depth, below in conjunction with the accompanying drawings and the present invention is carried out in detail by specific embodiment
Explanation.
See accompanying drawing 1, a kind of weld seam stretching bending experiment instrument that the present invention provides, including: it is used for pressing from both sides
Upper clamp 4 and lower clamp 7, the swing arm 3 of tight weld seam test specimen and be used for adjusting clamp 4 vertical position
Adjustment assembly；Lower clamp 7 is flexibly connected with swing arm 3；Swing arm 3 is placed in the top of lower clamp 7,
Clamp 7 can be relatively descended to overturn；Upper clamp 4 is arranged in swing arm 3 by adjusting assembly；Adjust regulation
Assembly can make clamp 4 opposed swing arms 3 vertically move.Lower clamp 7 clamps one end of weld seam test specimen,
Ensure that weld seam test specimen will not occur change in location, upper clamp 4 to clamp weld seam examination in bending drawing process
The other end of part, can be fixedly clamped weld seam test specimen.
As preferably, experiment instrument also includes: bearing 6；Swing arm 3 includes: crossbeam and side plate；Two
Side plate is vertically connected in the two ends of crossbeam；Lower clamp 7 both sides arrange pole；Bearing 6 is located in pole
On；The side plate bottom of swing arm 3 is connected on bearing 6；Bearing 6 coordinates with pole so that swing arm 3 energy
Clamp 7 is relatively descended to overturn.After weld seam test specimen is clamped by upper clamp 4 and lower clamp 7, operate swing arm
3 descend clamp 7 to overturn relatively, and now, swing arm 3 is back and forth transported with flexing roll 5 upper surface for axle center
Dynamic, thus ensure that this experiment instrument can make weld seam test specimen occur bending and deformation.
As preferably, adjusting part includes: screw rod 1 and nut 2；The crossbeam of swing arm 3 offers circular hole；
Circularhole diameter is less than the external diameter of nut 2；Screw rod 1 is located in circular hole；On the bottom of screw rod 1 is connected
Clamp 4；Rotating nut 2 can make to move or move down on the relative crossbeam of clamp 4.When on weld seam test specimen
After clamp 4 and the clamping of lower clamp 7, the bottom surface turning nut 2 to nut 2 contacts with beam surface,
Continuing to turn nut 2, the threaded function power between nut 2 and screw rod 1 passes to clamp 4 so that
Upper clamp 4 produces the trend of stretching weld seam test specimen, and now, weld seam test specimen bears the effect of tensile stress.
Therefore, this experiment instrument simulates at withdrawal straightening machine and three roller jockey pulleys on-the-spot during weld seam detection,
Weld seam test specimen is not only stretched power but also occur bending and deformation, it is possible to decrease owing to weld seam detection means deficiency is made
Become weld seam broken belt risk, and butt welded seam performance rating had quantify foundation.
As preferably, experiment instrument also includes: flexing roll 5；Flexing roll 5 is connected in the folder of lower clamp 7
Plate both sides.Equipped with two flexing rolls 5 on lower clamp 7, can make weld seam test specimen bending during by
Certain radian deforms, and the arc roll surface of flexing roll 5 can be prevented effectively from weld seam test specimen in the bending current political situation
Portion's stress is concentrated and is caused weld seam test specimen to rupture, and has ensured the accuracy of simulation experiment result.
A kind of weld seam stretching bending experiment instrument that the present invention provides is by arranging swing arm 3 and lower clamp 7
Movable connection structure ensures that this experiment instrument can make weld seam test specimen occur bending and deformation；By arranging adjustment group
The structure that part is connected with upper clamp 4 ensures that this experiment instrument can make the work that weld seam test specimen bears tensile stress
With.So this experiment instrument simulates the stressing conditions of cold rolling product line butt welded seam, reduces owing to weld seam is examined
The weld seam broken belt risk that survey means deficiency causes, improves the reliability of weld seam detection and comments for weldquality
Quantitative basis is provided surely.
Above-described detailed description of the invention, enters the purpose of the present invention, technical scheme and beneficial effect
Go further description, be it should be understood that the specific embodiment party that the foregoing is only the present invention
Formula, is not limited to the present invention, all within the spirit and principles in the present invention, that is done appoints
What amendment, equivalent, improvement etc., should be included within the scope of the present invention.
