Abstract
A kind of sample pickup tongs shank curved performance test frock, comprise fixed bin, described fixed bin is the box body of the hollow upper and lower opening in middle part, the retained part that can clamp fixing sample pickup tongs pincers portion is installed in described fixed bin, after the pincers portion of described sample pickup tongs is fixed on retained part, the shank of sample pickup tongs exposes described retained part, two opposite faces of described fixed bin are provided with bending screw rod to deserving to be called, and the working end of described bending screw rod is corresponding with shank position in fixed bin of sample pickup tongs.This patent structure is simple, size is less, greatly reduce testing cost and with strong points, can test out the ability that sample pickup tongs shank bears plastic yield in alternating bending.
Description
Technical field
This patent relate to a kind of sample pickup tongs shank curved performance test frock.
Technical background
Namely the existing method assessed metal material bending performance is standard GB/T/T238-2002 " metal wire rod alternating bending test method ", metal alternating bending test device structure now on the market made by this national standard is complicated, and have the requirement of size, pattern high to the metal material sample of test, not easily process, make greatly to increase time of material properties test and workload.
Utility model content
The purpose of this utility model is to provide for the deficiencies in the prior art that a kind of structure is simple, size is less, production cost is low, can clamp the sample pickup tongs shank curved performance test frock of the special sample pickup tongs cannot processed again of profile, for testing the shank bending performance of the sample pickup tongs that Ying Jie company produces.
The technical scheme of this patent is:
A kind of sample pickup tongs shank curved performance test frock, comprise fixed bin, described fixed bin is the box body of the hollow upper and lower opening in middle part, the retained part that can clamp fixing sample pickup tongs pincers portion is installed in described fixed bin, after the pincers portion of described sample pickup tongs is fixed on retained part, the shank of sample pickup tongs exposes described retained part, two opposite faces of described fixed bin are provided with bending screw rod to deserving to be called, and the working end of described bending screw rod is corresponding with shank position in fixed bin of sample pickup tongs.Described bending screw rod is rotated by artificial or driven by motor.
Described retained part comprises the fixture of two Mirror Symmetries, the plane of symmetry of two described fixtures is provided with the pickup groove matched with the pincers portion size of sample pickup tongs, the opening of described pickup groove is arranged on the upper side of described fixture, the pincers portion size of size and sample pickup tongs that two described fixture planes of symmetry connect rear described pickup groove relatively matches, after the pickup groove degree of depth makes the pincers portion of described sample pickup tongs insert pickup groove, the shank of sample pickup tongs exposes described pickup groove.
Described fixed bin wherein two opposite faces is arranged with the screw rod allowing the opposite face of two fixtures connect clamping, and another two opposite faces of described fixed bin are arranged with bending screw rod.
Owing to adopting such scheme, this device fixes sample pickup tongs by retained part, and allow the opposite face of two fixtures connect clamping by the screw rod on fixed bin, bent back and forth by the shank of bending screw rod to sample pickup tongs on another two opposite faces of fixed bin, bending screw rod can be rotated by artificial or driven by motor, the number of times of the shank fracture bending of test sample pickup tongs, thus show whether the shank of sample pickup tongs can be up to state standards, the relatively existing bending property test of this device, structure is simple, size is less, greatly reduce testing cost, and it is with strong points, the ability that sample pickup tongs shank bears plastic yield in alternating bending can be tested out.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model hold assembly.
Embodiment
Below by example, further describe the embodiment of this patent.
As Fig. 1, shown in 2, a kind of sample pickup tongs shank curved performance test frock, comprise fixed bin 1, described fixed bin 1 is the box body of the hollow upper and lower opening 2 in middle part, retained part 5 is installed with in described fixed bin 1, described retained part 5 comprises the fixture of two Mirror Symmetries, the plane of symmetry of two described fixtures is provided with the pickup groove 6 matched with sample pickup tongs size, the opening of described pickup groove 6 is arranged on the upper side of described fixture, two described fixture planes of symmetry relatively connect the rear size of described pickup groove and the size of sample pickup tongs matches, after the pickup groove degree of depth makes described sample pickup tongs insert pickup groove, the shank of sample pickup tongs exposes described pickup groove, described fixed bin 1 wherein two opposite faces is arranged with the screw rod 4 allowing the opposite face of two fixtures connect clamping, another two opposite faces of described fixed bin are arranged with bending screw rod 3, the position that after the working end of described bending screw rod 3 and described sample pickup tongs insert pickup groove, the shank of sample pickup tongs exposes pickup groove matches.
The pincers portion of sample pickup tongs complete " laminating " can clamp by retained part, thus carry out spacing when bending to the shank of sample pickup tongs, bending screw rod 3 is by successively rotating successively, realize carrying out push-and-pull to the shank of sample pickup tongs, thus make the shank of sample pickup tongs repeat bending, by operation so repeatedly, the bending number of times that the shank fracture recording sample pickup tongs needs just can complete measurement and the assessment of the repeated bending performance of sample pickup tongs shank, and bending number of times is more, bending property is better.
