Abstract
The invention discloses a steel bar bending tester. The steel bar bending tester comprises a pedestal. The pedestal is provided with two oppositely disposed supports. Each of the supports is provided with a supporting roller. The pedestal is provided with a stand. A hydraulic cylinder is disposed in the stand. The lower end of the hydraulic cylinder is connected to a pressing block. The outsides of the supports are provided with clamping apparatus. A steel bar is clamped at the clamping apparatus and is provided with a plurality of grooves. The steel bar bending tester has advantages of simple structure, increased efficiency and prolonged service lifetime.
Description
Technical field
The present invention relates to a kind of reinforcing steel bar bending tester.
Background technology
When with reinforcing steel bar bending tester, need to regulate the distance between roller according to the specification of reinforcing bar, at present, be to carry out distance between two rollers of condition by screw rod, but frequent owing to using, screw rod there will be the phenomenon of stripped thread, and screw rod also can be bending, be just difficult for having regulated; And briquetting is directly inserted in the lower end of hydraulic cylinder, because briquetting will be subject to very large pressure, so the junction of briquetting is easy to fracture, affect serviceable life.
Summary of the invention
The object of the invention is in order to overcome above deficiency, provide a kind of simple in structure, raise the efficiency, improve the reinforcing steel bar bending tester in serviceable life.
Object of the present invention is achieved through the following technical solutions: a kind of reinforcing steel bar bending tester, comprise base, base is provided with two bearings that are oppositely arranged, in two bearings, be equipped with a roller, base is provided with support, is provided with hydraulic cylinder in support, hydraulic cylinder lower end is connected with briquetting, the outside of two bearings is equipped with jig, and on jig, card has steel bar, steel bar to be provided with multiple grooves.
Further improvement of the present invention is: the lower end of hydraulic cylinder is provided with the first abutment ring and the second abutment ring successively, in the first abutment ring and the second abutment ring, run through and be provided with bolt, the bottom of bolt is connected with contiguous block, is provided with T-shaped groove in contiguous block, and in T-shaped groove, card has briquetting.
Further improvement of the present invention is: the internal diameter of the first abutment ring is greater than the internal diameter of the second abutment ring.
The present invention compared with prior art has the following advantages: the present invention adopts steel bar to replace original screw-rod structure, on steel band, be provided with different grooves according to the diameter of different reinforcing bars, when use, briquetting is adjusted in different grooves and just can two of easy adjustment have propped up the distance between rollers, convenient to operation, improve operating efficiency, and improved the serviceable life of equipment; The lower end of hydraulic cylinder is connected with contiguous block by two abutment rings, and transverse part volume in T-shaped groove becomes greatly, and briquetting is just not easy to rupture like this, the serviceable life that has increased briquetting.
brief description of the drawings:
Fig. 1 is structural representation of the present invention;
Number in the figure: 1-base, 2-bearing, 3-prop up roller, 4-support, 5-hydraulic cylinder, 6-briquetting, 7-jig, 8-steel bar, 9-groove, 10-the first abutment ring, 11-the second abutment ring, 12-bolt, 13-contiguous block, 14-T type groove.
embodiment:
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment only, for explaining the present invention, does not form limiting the scope of the present invention.
As Fig. 1 shows a kind of embodiment of reinforcing steel bar bending tester of the present invention, comprise base 1, base 1 is provided with two bearings that are oppositely arranged 2, in two bearings 2, be equipped with a roller 3, base 1 is provided with support 4, is provided with hydraulic cylinder 5 in support 4, hydraulic cylinder 5 lower ends are connected with briquetting 6, the outside of two bearings 2 is equipped with jig 7, and on jig 7, card has steel bar 8, steel bar 8 to be provided with multiple grooves 9.The lower end of hydraulic cylinder 5 is provided with the first abutment ring 10 and the second abutment ring 11 successively, in the first abutment ring 10 and the second abutment ring 11, run through and be provided with bolt 12, the bottom of bolt 12 is connected with contiguous block 13, is provided with T-shaped groove 14 in contiguous block 13, and in T-shaped groove 14, card has briquetting 6.The internal diameter of the first abutment ring 10 is greater than the internal diameter of the second abutment ring 11.
The present invention adopts steel bar to replace original screw-rod structure, on steel band, be provided with different grooves according to the diameter of different reinforcing bars, when use, briquetting is adjusted in different grooves and just can two of easy adjustment have propped up the distance between rollers, convenient to operation, improve operating efficiency, and improved the serviceable life of equipment; The lower end of hydraulic cylinder is connected with contiguous block by two abutment rings, and transverse part volume in T-shaped groove becomes greatly, and briquetting is just not easy to rupture like this, the serviceable life that has increased briquetting.
