Abstract
The utility model belongs to the field of wire experiment equipment, and provides a wire bending device with resistance testing. The device comprises a fixing device and a testing device, wherein the fixing device consists of two springs that the outer ends are fixed and the inner ends are connected with two ends of a wire to be tested; the testing device is arranged between the two springs; the testing device comprises a tension meter for tensioning the wire to be tested and a resistance tester for testing the resistance of the wire to be tested. Through the adoption of the wire bending device with resistance testing, the problems that the conventional wire bending device is complex in structure, expensive in price and inconvenient to use for small factories or temporary construction fields are solved; as the wire bending device with resistance testing uses the resistance tester to test the resistance of the wire, the wire bending degree can be reflected from the resistance of the wire; meanwhile, the components can be disassembled to use separately, so that the wire bending device is simple in structure, convenient to use and economic and practical, and the requirements of small factories and temporary construction fields on the bending testing on cables can be met.
Description
Technical field
The utility model relates to wire rod testing equipment field, relates in particular to a kind of wire rod bending device that resistance detects that has.
Background technology
Electric wire is a kind of in order to transmit electricity (magnetic) energy, information and to realize the wire product that electromagnetic energy is changed, and electric wire can be referred to as cable.Cable in use often can bend to various shapes; after alternating bending, the core in cable may fracture, and causes electric discontinuity of cable; therefore should carry out bending test to cables such as power lead, DC lines, investigate the crack conditions of cable after the bending of certain angle, number of times.Existing wire rod bending device complex structure, expensive, be not suitable for midget plant or the use of interim building site.
Summary of the invention
The purpose of this utility model is: solve existing wire rod bending device complex structure, and expensive, the problem that midget plant or interim building site are inconvenient to use.
The technical scheme that the utility model is taked for solving existing issue: a kind of wire rod bending device with resistance detection, comprise stationary installation and pick-up unit, stationary installation is that two outer ends are fixed, the inner spring that connects wire rod to be measured two ends, pick-up unit is arranged between these two springs, and pick-up unit comprises for the tautness meter of tractive wire rod to be measured with for detection of the resistance meter of the resistance value of wire rod to be measured.
Described tautness meter is connected with the central point of described wire rod to be measured.
Described tautness meter is digital display type or pointer-type.
The test lead of described tautness meter is connected with wire rod to be measured by connection cord.
The beneficial effects of the utility model: a kind of wire rod bending device that resistance detects that has is provided, comprise stationary installation and pick-up unit, stationary installation is that two outer ends are fixed, the inner spring that connects wire rod to be measured two ends, pick-up unit is arranged between these two springs, pick-up unit comprises for the tautness meter of tractive wire rod to be measured with for detection of the resistance meter of the resistance value of wire rod to be measured, this wire rod bending device with resistance detection solves existing wire rod bending device complex structure, expensive, the problem that midget plant or interim building site are inconvenient to use, because this wire rod bending device with resistance detection is used resistance meter to measure wire rod resistance, from wire rod resistance, can find out wire rod bending degree, the detachable independent use of parts simultaneously, simple in structure, easy to use, economical and practical, can solve the requirement to cable bending test of midget plant or interim building site.
Accompanying drawing explanation
Fig. 1 is a kind of schematic diagram with the wire rod bending device of resistance detection.
In figure: 1, stationary installation; 2, tautness meter; 3, resistance meter; 4, wire rod to be measured; 5, connection cord.
Embodiment
A kind of as shown in Figure 1 have a wire rod bending device that resistance detects, comprise stationary installation and pick-up unit, stationary installation is that two outer ends are fixed, the inner spring 1 that connects wire rod to be measured 4 two ends, pick-up unit is arranged between these two springs 1, and pick-up unit comprises for the tautness meter 2 of tractive wire rod 4 to be measured with for detection of the resistance meter 3 of the resistance value of wire rod 4 to be measured.
During test, by pulling force meter 2, make the bending of 4 one-tenth 90 degree of wire rod to be measured, tautness meter 2 is not during the application of force, under the effect of two spring 1 pulling force, wire rod 4 to be measured recovers certain deformation, repeat above-mentioned action, until resistance meter 3 is shown as, within 0 o'clock, be that wire rod records tautness meter application of force number of times while fractureing, the bend resistance ability of known wire rod to be measured 4, is convenient to wire rod performance analyze and improve.
Embodiment 3
Embodiment 4
The present embodiment and embodiment 2 structures are basic identical, and difference is that tautness meter passes through connection cord 5 and is connected with cable to be measured 4 middles, larger at wire rod 4 diameters to be measured, uses connection cord 5 in the time of cannot being directly connected with tautness meter 2.The holding capacity of connection cord 5 must be greater than the holding capacity of wire rod 4 to be measured.
More than exemplifying is only to illustrate of the present utility model, does not form the restriction to protection domain of the present utility model, within the every and same or analogous design of the utility model all belongs to protection domain of the present utility model.
