Abstract

The invention discloses a kind of reinforcing steel bar bending tester, comprise base, base is provided with two bearings be oppositely arranged, be equipped with a roller in two bearings, 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, and steel bar is provided with multiple groove.The present invention have structure simple, raise the efficiency, improve the advantage in serviceable life.

Description

Reinforcing steel bar bending tester
Technical field
The present invention relates to a kind of reinforcing steel bar bending tester.
Background technology
Needing when using reinforcing steel bar bending tester to regulate the distance between a roller according to the specification of reinforcing bar, at present, is regulate distance between two rollers by screw rod, but frequent owing to using, screw rod there will be the phenomenon of stripped thread, and screw rod also can bend, just not easily have adjusted; 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, have impact on serviceable life.
Summary of the invention
The object of the invention is to overcome above deficiency, provide a kind of structure simple, 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 be oppositely arranged, be equipped with a roller in two bearings, 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, and steel bar is provided with multiple groove.
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, run through in first abutment ring and the second abutment ring 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, steel bar is provided with different grooves according to the diameter of different reinforcing bar, during use, jig is adjusted in different grooves and just easy adjustment two can props up the distance between roller, convenient to operation, improve operating efficiency, and improve the serviceable life of equipment; The lower end of hydraulic cylinder is connected with contiguous block by two abutment rings, and the transverse part volume in T-shaped groove becomes large, and such briquetting is just not easy fracture, increases the serviceable life of briquetting.
accompanying drawing illustrates:
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-first abutment ring, 11-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 be oppositely arranged 2, be equipped with a roller 3 in two bearings 2, base 1 is provided with support 4, is provided with hydraulic cylinder 5 in support 4, hydraulic cylinder 5 lower end is connected with briquetting 6, the outside of two bearings 2 is equipped with jig 7, and on jig 7, card has steel bar 8, and steel bar 8 is provided with multiple groove 9.The lower end of hydraulic cylinder 5 is provided with the first abutment ring 10 and the second abutment ring 11 successively, run through in first abutment ring 10 and the second abutment ring 11 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, steel bar is provided with different grooves according to the diameter of different reinforcing bar, during use, jig is adjusted in different grooves and just easy adjustment two can props up the distance between roller, convenient to operation, improve operating efficiency, and improve the serviceable life of equipment; The lower end of hydraulic cylinder is connected with contiguous block by two abutment rings, and the transverse part volume in T-shaped groove becomes large, and such briquetting is just not easy fracture, increases the serviceable life of briquetting.
