Abstract

The utility model belongs to the technical field of wiredrawing equipment, and particularly relates to a metal wire bend tester. The utility model has the main technical scheme that the metal wire bend tester comprises a tester stand, and a swinging mechanism and a control mechanism are fixed on the tester stand; the side of the stand is provided with a swing fixed plate fixedly connected with an output shaft of the swinging mechanism; a support seat used for fixing and supporting a metal wire bending roll pair and an lower metal wire bayonet is arranged at the lower side of the swing fixed plate; the swing fixed plate is provided with a pressure spring mechanism, an upper metal wire bayonet and a center sleeve from top to bottom; the support seat has a vertical metal wire through hole; a lifting hook corresponding to the vertical metal wire through hole is arranged at the lower side of the vertical metal wire through hole in the support seat. After the metal wire bend tester is adopted, the steel wire bending performance detection error can be reduced, and the accuracy of detection performance parameters can be guaranteed.

Description

A kind of tinsel Flexing Apparatus
Technical field
The utility model belongs to tinsel experiments of measuring equipment technical field, relates in particular to a kind of tinsel Flexing Apparatus.
Background technology
In Steel Wire Products Industry, the toughness index of steel wire is by Flexing Apparatus, steel wire to be carried out the alternating bending of 180 °, records that steel wire fracture front curve number of times characterizes out, and general bending number of times is larger, and steel wire toughness is better.Existing test standard is that GB238 is equal to ISO7801 standard regulation: when test, " make sample perpendicular to cylinder bearing axis ", " tensile force applying must not exceed sample nominal tensile strength relative stress value 2% ".Because the defect on testing machine structure causes: one, in the time of the fixing tinsel of testing, be merely able to observing by laboratory technician, stretching steel wire head end " vertically " is clamped in lower bayonet socket, this operation both cannot guarantee that steel wire was vertical with cylinder bearing axis, more cannot guarantee that steel wire overlaps with the neutral line of sleeve pipe above, affects the accuracy of experimental result greatly; They are two years old, while applying tensile force, when laboratory technician is displaced downwardly to appropriate amount by hand nut to upper latch notch, tighten upper latch notch screw and clamp steel wire, when test, the tensile force of steel wire equals the elastic force of the volume under pressure generation of spring, power value is difficult to definite, and the volume under pressure that different experiments person controls can not guarantee unanimously, test findings stability and repeated very poor.
Utility model content
The purpose of this utility model is just to provide a kind of tinsel Flexing Apparatus that can reduce steel wire bending property detection error.
Realizing the technical scheme that the utility model above-mentioned purpose adopts is:
A kind of tinsel Flexing Apparatus, comprise the testing machine frame that is fixed with wabbler mechanism and control gear, the sidepiece of this frame is provided with the fixed head that waves being fixedly connected with the output shaft of described wabbler mechanism, this wave fixed head downside be provided with for fixing and support wire bending roll to the supporting seat of lower buckle, at the described pressure spring mechanism, tinsel upper latch notch, the cylindrical central sleeve that arrange from top to bottom on fixed head of waving, in described supporting seat, be provided with tinsel and vertically bore a hole; It is characterized in that: the downside setting of vertically boring a hole of the tinsel in described supporting seat is provided with suspension hook by correspondence with it.
In addition, in the structure of the above-mentioned a kind of tinsel Flexing Apparatus of formation, described suspension hook place is provided with draws heavy counterweight and pallet thereof.
A kind of tinsel Flexing Apparatus provided by the utility model compared with prior art has the following advantages: one, due to form testing machine the setting of supporting seat downside by with the vertical corresponding suspension hook of boring a hole of supporting seat center tinsel, therefore can guarantee that tinsel dangles through suspension hook must be perpendicular to cylindrical sleeves bearing axis, effectively avoid tinsel to be drawn the generation of inclined to one side phenomenon, improved the accuracy of test; Its two, because tested end wiry is stretching by vertical drop-down hook, and can determine the weight of stretching used counterweight, therefore can make the drop-down power of pressure spring mechanism accurate, can further improve the accuracy of institute's test parameter.
Accompanying drawing explanation
Fig. 1: the side-looking structural representation of the tinsel Flexing Apparatus providing for the utility model;
Fig. 2: for forming the Facad structure schematic diagram of above-mentioned tinsel Flexing Apparatus.
Embodiment
Concrete structure and use principle below in conjunction with accompanying drawing to a kind of tinsel Flexing Apparatus provided by the utility model are described in further detail.
As shown in Figure 1, 2, for forming the structural representation of a kind of tinsel Flexing Apparatus provided by the utility model.The structure that forms this testing machine comprises the testing machine frame 2 that is fixed with wabbler mechanism 12 and control gear 1, the sidepiece of this frame be provided be fixedly connected with the output shaft of wabbler mechanism wave fixed head 4, wave being provided with for fixing and support wire bending roll 9 and the supporting seat 11 of lower buckle 10 of downside of fixed head 4 at this, waving the pressure spring mechanism 6 arranging on fixed head from top to bottom, tinsel upper latch notch 7, cylindrical central sleeve 8 and be arranged at supporting seat 11 downsides and be arranged at the corresponding suspension hook 13 that is provided with of the vertical perforation 14 of supporting seat center tinsel, this suspension hook place is provided with draws heavy counterweight 15 pallets 16.
When use, while performance parameter wiry being detected to measurement, first steel wire head being arranged to a crotch 17 hangs up suspension hook, and tinsel is passed to lower bayonet socket successively, cylindrical central sleeve, upper latch notch, twisting with the fingers termination wiry mentions suspension hook and fixes with pressure spring mechanism, tighten upper latch notch, according to different size tinsel and intensity thereof, calculate the tensile force needing, on suspension hook, add the counterweight needing, holding tinsel stops swinging, clamp lower bayonet socket, at this moment the counterweight weight sum that spring force equals suspension hook and applies, equal the tensile force of steel wire, tinsel dangles through suspension hook, must be perpendicular to cylindrical sleeves bearing axis, rear unlatching has the wabbler mechanism of control gear control, making to wave fixed head starts to wave, and drive the tinsel of surveying to wave bending between tinsel bending roll, to the test to realize the performance parameters such as tinsel intensity.
In the structure of above-mentioned tinsel Flexing Apparatus, draw the hook of heavy counterweight being only subject to neutral effect owing to hanging with, therefore can guarantee that sample wiry is perpendicular to cylindrical sleeves axis, sample on the center line of sleeve pipe or very approaching, has effectively improved the accuracy of test.
