In the invention, mechanical scoring is adopted for completing the gauge length work, the accuracy is high, and the workload is small.

Description

A kind of reinforcing bar gauge length instrument
Technical field
The present invention relates to a kind of steel bar mechanics performance test device, specifically a kind of reinforcing bar gauge length instrument.
Background technology
Elongation after fracture is an important indicator in the steel mechanics performance, and elongation after fracture is meant the difference and the original gauge length ratio of the have no progeny gauge length and the original gauge length of steel, represents with %.
As requested, when carrying out the steel mechanics performance test, the original gauge length of hot calendering round bar and hot rolled ribbed steel bar is 5 times a bar diameter, adopts the mode of artificial mark distance before steel bar stretching reinforcing bar to be carried out original gauge length at present usually.The shortcoming of this mode is: artificial mark distance, be easy to generate error, and influence accuracy of experimental results; And workload is big, cumbersome, and efficient is low.
Summary of the invention
In order to overcome at present artificial mark apart from the problem that mode exists, the purpose of this invention is to provide a kind of reinforcing bar gauge length instrument, this reinforcing bar gauge length instrument adopts mechanical score to finish gauge length work, the accuracy rate height, workload is little.
The objective of the invention is to be achieved through the following technical solutions:
A kind of reinforcing bar gauge length instrument is characterized in that: this gauge length instrument comprises support, is provided with rotating shaft on support, and rotating shaft is connected with handwheel by worm reduction box; In rotating shaft, be provided with one group with the suitable screw rod mounting hole in gauge length position, in the screw rod mounting hole, be provided with screw rod, be provided with the gauge length blade in the screw rod end; The two ends that are positioned at the screw rod mounting hole in rotating shaft are provided with the reinforcing bar fixed head, are provided with the reinforcing bar fixed orifice on the reinforcing bar fixed head.
Among the present invention, described reinforcing bar fixed head is three layers, and one deck is arranged on the upper end of screw rod mounting hole, all the other two-layer lower ends that are arranged on the screw rod mounting hole.Described reinforcing bar fixed head can be circular slab, and one group of reinforcing bar fixed orifice is evenly distributed on the circumference of circular reinforcing bar fixed head.
The present invention is provided with the reinforcing bar fixed orifice of all size reinforcing bar on the reinforcing bar fixed head, can once place φ 6-φ 32 12 groups of steel samples of totally 12 kinds of specifications, adopt mechanical score to finish gauge length work, as long as allow rotating shaft rotate 30 degree, the disposable original gauge length indentation work of finishing 12 groups of steel samples.Compared with prior art, accuracy rate height of the present invention, little, the high efficiency of workload.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the structural representation of reinforcing bar fixed head among the present invention;
Fig. 3 is the structural representation of shaft of the present invention;
Fig. 4 is the structural representation of screw rod and gauge length blade among the present invention.
Embodiment
A kind of reinforcing bar gauge length instrument of the present invention is seen Fig. 1, and this gauge length instrument comprises support 1, is provided with rotating shaft 6 on support 1, and rotating shaft 6 is connected with handwheel 5 by worm reduction box 4; In rotating shaft 6, be provided with one group with the suitable screw rod mounting hole 61 in reinforcing bar gauge length position, in screw rod mounting hole 61, be provided with screw rod 7, be provided with gauge length blade 3 in screw rod 7 ends; The two ends that are positioned at screw rod mounting hole 61 in rotating shaft 6 are provided with reinforcing bar fixed head 2, are provided with reinforcing bar fixed orifice 21 on reinforcing bar fixed head 2.Reinforcing bar fixed head 2 is three layers, and one deck is arranged on the upper end of screw rod mounting hole 61, all the other two-layer lower ends that are arranged on screw rod mounting hole 61.Reinforcing bar fixed head 2 is a circular slab, and one group of reinforcing bar fixed orifice 21 is evenly distributed on the circumference of circular reinforcing bar fixed head 2.Reinforcing bar fixed orifice 21 is suitable with all size reinforcing bar, can once place φ 6-φ 32 12 groups of steel samples of totally 12 kinds of specifications.
Principle of work of the present invention is as follows:
Fig. 2 is the structural representation of reinforcing bar fixed head among the present invention; Fig. 3 is the structural representation of shaft of the present invention; Fig. 4 is the structural representation of screw rod and gauge length blade among the present invention.The reinforcing bar that needs gauge length is inserted in the reinforcing bar fixed orifice 21.In rotating shaft 6, the screw rod 7 that has alloy steel gauge length blade 3 is installed by screw rod mounting hole 61, the distance that gauge length blade on this screw rod 7 is 3 is the gauge length of various steel, rotate handwheel 5, drive rotating shaft 6 by worm reduction box 4 and rotate 30 degree, the various reinforcing bar samples that gauge length blade 3 just will be placed on the reinforcing bar fixed head 2 are once finished the gauge length indentation.
The present invention can once place φ 6-φ 32 12 groups of steel samples of totally 12 kinds of specifications, 2 on every kind of specification steel sample, can directly put into corresponding reinforcing bar fixed orifice position, utilize devices such as worm and gear, rotating shaft, as long as with rotating shaft rotation 30 degree, can finish the work of gauge length indentation with 12 groups of steel samples putting into are disposable, increase work efficiency greatly, reduce manipulation strength.Adopt mechanical score to finish gauge length work, the accuracy rate height, workload is little, as long as allow main shaft rotate 30 degree, the disposable original gauge length indentation work of finishing 12 groups of steel samples.
