Description
Technical Field
The utility model relates to an kinds of plastics ribbon fastening power testing arrangement especially relates to kinds of ribbon fastening power test fixture.
Background
Plastic tie is now used in a wide variety of industries where it is desirable to secure lashes, particularly in the electrical industry, in the time sexual life field, plastic tie is also used in the fastening of hose to joint connections, and therefore places relatively stringent requirements on the fastening force of plastic ties, which can lead to loosening of the tie when the fastening force is insufficient, indicating leakage in time use systems.
SUMMERY OF THE UTILITY MODEL
The utility model provides an kinds of ribbon fastening force test fixture has solved and has tested the fastening force after tying up the plastics ribbon to read the problem of the power value when the ribbon became invalid, its technical scheme as follows:
kind of ribbon fastening power test fixture, including steel sheet and semi-circular metal block, semi-circular metal block includes the bottom surface of rectangle, the semi-circular side of left and right sides, and connect the extrados of above-mentioned three faces, the terminal surface of steel sheet is provided with through-holes, end welding is in the highest point of extrados in addition, the centre of a circle line of the semi-circular side of semi-circular metal block left and right sides, be on a parallel with the welding line between steel sheet and the semi-circular metal block, be provided with ring shape recesses in extrados middle part, be arranged in being fixed in the recess with the plastics ribbon.
The two ends of the circular groove are connected with the bottom surface.
The distance between the left side and the right side of the steel plate is the same as the distance between the left side and the right side of the semicircular metal block.
The plane of the steel plate is vertical to the bottom surface.
The utility model discloses following beneficial effect has:
1. the clamp has a very simple structure and low manufacturing cost;
2. the binding belt is fixed in the groove during measurement and cannot slide randomly;
3. the test fixture simulates the actual situation of the cable tie in use, and the obtained result has certain credibility;
4. the fixture is simple and convenient to mount and dismount during testing, and the operation time is saved.

Detailed Description
As shown in fig. 1 to 3, the band fastening force test jig includes an upper steel plate 1 and a lower semicircular metal block 4, which are formed by metal welding as in .
The two semicircular metal blocks 4 with the same shape can form cylinders, and the semicircular metal blocks 4 are half of the cylinders after being cut from a plane passing through the central axis of the cylinders, and comprise a bottom surface, a left semicircular surface, a right semicircular surface and an extrados surface connected with the three surfaces.
The steel plate 1 is vertically welded at the highest part of the outer arc surface of the semicircular metal block 4, and as can be seen in the combination of fig. 2, the bottom surface of the semicircular metal block 4 is vertical to the steel plate 1.
The steel plate 1 of the upper half is made of a steel plate of suitable thickness, the surface of which is provided with through holes 2 for connection with the clamping jaws 5 of a tensile tester as shown in fig. 4.
In the figure 2, two ends of the circular grooves 3 are connected to the bottom surface, the radius B from the circle center to the groove is smaller than the radius A of the semicircular metal block 4, after the upper half part and the lower half part are welded, the verticality of the steel plate 1 and the lower semicircular metal block 4 is ensured, the force value reading is avoided being inaccurate, and two same clamps are required to be matched for use during testing.
As shown in fig. 4 and 5, the two band tightening force test jigs are arranged oppositely, and the two semicircular metal blocks 4 form a cylinder, and on the outer surface of the cylinder, a circular groove 3 is formed around the outer surface .
The upper clamping jaw 5 and the lower clamping jaw 5 of the tension tester are connected with the steel plate 1, and the binding belt fastening force testing clamp is connected and fixed with the clamping jaws 5 through the bolts 6 and the nuts 7. because the upper clamping jaw 5 and the lower clamping jaw 5 only use connection points, the tension line can be ensured to be positioned on the same straight lines during testing, and errors are reduced.
During testing, the cable tie shown in fig. 6 is passed through the groove on the test fixture and fixed as shown in fig. 2, then the cable tie is cut off by using a cable tie gun, and at the moment, the pawl at the head of the cable tie is fixed in the groove on the surface of the cable tie and cannot slide randomly, so that the binding and fastening are realized.
Start the tension tester, tension tester clamping jaw 5 can drive test fixture, and test fixture's interval can enlarge gradually from top to bottom, until the pawl with the ribbon head is broken or other positions of ribbon fracture, alright read the pulling force value from the tension tester this moment to confirm whether the ribbon can carry out reliable fastening according to this power value.
The utility model has simple structure and low manufacturing cost, and the ribbon is fixed in the groove and can not slide randomly during measurement; the fixture is simple and convenient to mount and dismount during testing, and the operation time is saved.
Claims (4)
