Mainly solving thin material is less than or equal to 0.3mm, utmost point thin metal board, metal foil) the parallel end L of tensile sample sticks up, and the manual handling produces the technical problem of crease, technical scheme easily: a straightener of tensile sample, characterized by includes sample base, slide rail, sample centre gripping pincers and straightening mechanism, sample centre gripping pincers are U shaped steel, and the closed end setting is at sample base surface both ends, and sample centre gripping pincers the first half is opened there is the screw has in, and connects the bolt soon, the slide rail is parallel lines formula slide rail, through the bolt fastening on the sample base, straightening mechanism fixes on the slide rail slider. The aligning of device mainly used thin material tensile sample is mainly aligned the parallel end L of tensile sample and is stuck up, also has certain improvement effect to sample distortion and smooth sea shape.
Description
Technical field
The utility model relates to a kind of straightening device, in particular to the straightening device of a kind of tension specimen. Device is mainly used in the straightening device of thin material (0.3mm) following tension specimen, and the main aligning parallel end L of tension specimen sticks up, and sample distortion and smooth sea shape is also had some improvement.
Background technology
It is do the precondition of tension specimen that cold rolling mechanics sample possesses good planeness, but in the detection of reality, source and the state of sample are more complicated, add the reason that sample is processed, cold-reduced sheet sample (0.3mm) internal stress local accumulation or the release after sample preparation that particularly sample thickness is partially thin, more easily occur that L sticks up and the phenomenon of sample distortion, the full-automatic stretching experiment machine of the mechanical test ZWICK of current cold-reduced sheet sample (i.e. the dimensional measurement of sample and send sample trier automatically to complete), when the L of sample stick up exceed to a certain degree time, likely can produce two consequences: mechanical manipulator is grabbed less than sample on the one hand, sample drop test platform, the automatic step of trier is interrupted, need to restart trier, self-inspection again, relatively time-consuming, affect working efficiency, on the other hand sample and mechanical manipulator interfere collision, and sample can be hit distortion distortion, thus block mechanical manipulator cannot action, test is forced to interruption. distort serious sample and require, because not meeting sample, process of can only cancelling. according to long-time observation and practice, it has been found that the parallel end that the major cause that sample generation L sticks up is reduced sectien specimen produces warpage. even if clamping end is straight, if parallel end is not straight, warpage still can be produced. current testing staff processes the method that L sticks up two kinds, all not fully up to expectations. method presses a for some time the sample weight of warpage, but after weight releasing, owing to distortion is elasticity distortion, sample is warpage still. another kind of method is for being manually sample is pulled directly, but easily occurs viscous deformation folding line then occur at parallel end, can rupture from folding line during fracture when doing tension test, makes the tensile strength measured and elongation after fracture value inaccurate. therefore with mechanism, sample must be aligned for thin material warpage. so that tests carries out smoothly.
Through retrieval, Chinese patent 2015203292961 discloses a kind of straightener, and this straightener is used for steel band aligning, although being also by the mode to roller reinforcing, but its structure is comparatively complicated. But not yet retrieve domestic overstretching sample straightening device at present.
Summary of the invention
The purpose of this utility model is to provide the straightening device of a kind of tension specimen, mainly solve thin material (0.3mm, pole sheet metal, metal foil) the parallel end L of tension specimen sticks up, manual handling easily produces the technical problem of folding line, and sample distortion and smooth sea shape are also had some improvement by the utility model.
The technical solution adopted in the utility model is: the straightening device of a kind of tension specimen, comprises specimen mount, slide rail, sample holder pincers and straightening mechanism.

Embodiment
With reference to Fig. 1,2,3,4, the straightening device of a kind of tension specimen, comprise specimen mount 2, slide rail 3, sample holder pincers 1 and straightening mechanism 4.
Described specimen mount 2 is rectangular parallelepiped metallic object, for the fixing of various components and parts and support; As required matrix is equipped with threaded hole.
Described sample holder pincers 1 are U-shaped steel, and closed end is arranged on two ends, specimen mount 2 surface, and upper part has screw, and inside spin bolt, and bolt screws the clamping end for fixing sample. Bolt screws the clamping end for fixing sample.
Slide rail 3 is parallel orthoscopic slide rail, is bolted in specimen mount 2, and straightening mechanism 4 is fixed on slide rail 3 slide block.
Straightening mechanism 4 comprises working roll pedestal 43, upper working roll unit 41 and bottom working roll unit 42, upper working roll unit 41 is rotatably connected and is fixed on above working roll pedestal 43, bottom working roll unit 42 is fixed on working roll pedestal 43, upper working roll unit 41 is a roller, and bottom working roll unit 42 is two rollers of parallel setting.
The straightening device using method of tension specimen, comprises the following steps: a, the clamping end fixing tension specimen one end with sample holder pincers, tightens sample holder pincers screw, sample holder end is able to fully fixing. One end clamping end and gripper clamp gentle touchdown in addition, but guarantee mobile. Namely one end is fixed, in addition one end relative relaxation.
B, the working cell contact parallel end of sample. In rotation, the working roll of working roll unit 41 touches the parallel end of tension specimen, the pressure that artificial applying is certain. Make working roll unit 41 and bottom working roll unit 42 produce the overlapping amount of trace, make sample that slight flexural deformation occur.
C, shifting sledge 3, the fully parallel end of aligning. Shifting sledge repeatedly, makes sample parallel ends divide and all covers and align. In the process of aligning, the length on tension specimen is longitudinal is elongated, due to other one end relative relaxation, it is possible to make the sample of aligning free one's minds and fully extended.
D, sample upper and lower surface overturn, and repeat above operation. Until obtaining satisfied paralleled end plates shape.
