A bending testing machine for reinforcing bar detection

Abstract

The utility model relates to the technical field of building engineering inspection, and specifically discloses a bending testing machine for reinforcing bar detection, which comprises a reinforcing bar bending testing machine body fixed to the ground, a side base detachably fixed to the upper surface of the reinforcing bar bending testing machine body, a limiting groove symmetrically formed in the side base, two limiting shafts slidingly inserted into the limiting groove, and a limiting sleeve plate sleeved to the two ends of the limiting shafts. By moving the position of the limiting shaft in the limiting groove, the protective cover plate fixed to the limiting shaft can be switched between the horizontal state and the vertical state, so that the reinforcing bar can be placed on the upper surface of the reinforcing bar bending testing machine body when the protective cover plate is vertical. When the bending test is performed on the reinforcing bar, the protective cover plate is moved to the horizontal state to limit the displacement of the reinforcing bar, so that the reinforcing bar is confined in the limited space formed between the protective cover plate and the reinforcing bar bending testing machine body, thereby ensuring safety.

Description

Technical Field

[0001] This utility model relates to the field of building engineering inspection technology, specifically a bending test machine for reinforcing steel bars. Background Technology

[0002] The rebar bending test machine is a specialized device for conducting cold bending tests and reverse planar bending tests on rebars. The equipment consists of a frame, worktable, reducer, clamping device and electrical control system. It is used in metallurgy, machinery manufacturing, construction and quality supervision and can determine the plastic bending capacity and bending resistance of rebars.

[0003] Chinese invention patent CN103994932B, published on April 20, 2016, discloses a rebar bending testing machine, including a base, two opposing supports on the base, each support having a support roller, a bracket on the base, a hydraulic cylinder in the bracket, a pressure block connected to the lower end of the hydraulic cylinder, and clamps on the outer sides of the two supports, with steel bars clamped on the clamps, and multiple grooves on the steel bars; the invention has the advantages of simple structure, improved efficiency, and extended service life.

[0004] However, the above-mentioned publicly disclosed solutions have the following shortcomings: the existing steel bar bending test machine, in addition to bending by contacting the upper and lower parts, does not have a limiting structure, which means that the precise position of the steel bar must be carefully controlled when conducting the steel bar bending test. Otherwise, the steel bar may easily break apart during bending, causing danger. Utility Model Content

[0005] The purpose of this invention is to solve the technical problem that existing steel bar bending testing machines, which only involve bending under pressure from above and below without a limiting structure, require precise placement of the steel bars during bending tests. Otherwise, the steel bars may easily break apart during bending, posing a danger. This invention provides a steel bar bending testing machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution;

[0007] The present invention discloses a rebar bending test machine, comprising a rebar bending test machine body fixed to the ground; a side base is detachably fixed to the upper surface of the rebar bending test machine body; symmetrically provided limiting grooves are provided on the side bases; two limiting shafts are slidably inserted into the limiting grooves; limiting sleeves are sleeved at both ends of the limiting shafts; and protective cover plates are sleeved on the limiting shafts.

[0008] Furthermore, multiple handles are fixed to the upper surface of the protective cover.

[0009] Furthermore, a plurality of limiting baffles are fixedly connected to the lower surface of the protective cover.

[0010] The bending test machine for reinforcing bar testing provided by this utility model has the following beneficial effects:

[0011] 1. This utility model moves the limiting shaft within the limiting groove, thereby switching the protective cover plate fixed on the limiting shaft between a horizontal and a vertical state. When the protective cover plate is vertical, reinforcing bars can be placed and removed onto the upper surface of the reinforcing bar bending test machine body. Then, when the reinforcing bar is bent, the protective cover plate is moved to a horizontal state, restricting the displacement of the reinforcing bar, thus confining it within the limited space formed between the protective cover plate and the reinforcing bar bending test machine body, thereby enhancing safety.

[0012] 2. This utility model provides gripping positions through multiple handles, making it more convenient and quick to switch between the vertical and horizontal states of the protective cover; the limiting baffle extends into the gaps on the upper surface of the rebar bending test machine body, thereby further restricting the flying path of the rebar and thus making the protection effect better.

[0018] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0019] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] It should be noted that all directional indications (such as up-down-left-right-forward-backward...) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0021] Please see Figure 1-3 As shown, a rebar bending test machine includes a rebar bending test machine body 1 fixed to the ground; a side base 2 is detachably fixed to the upper surface of the rebar bending test machine body 1; symmetrically formed limiting grooves 4 are formed on the side base 2; two limiting shafts 5 are slidably inserted into the limiting grooves 4; limiting sleeves 6 are sleeved at both ends of the limiting shafts 5; protective cover plates 7 are sleeved on the limiting shafts 5. By moving the position of the limiting shafts 5 in the limiting grooves 4, the protective cover plates 7 fixed on the limiting shafts 5 are switched between a horizontal state and a vertical state. When the protective cover plates 7 are vertical, rebars can be placed and removed from the upper surface of the rebar bending test machine body 1; then, when the rebar is bent, the protective cover plates 7 are moved to a horizontal state to restrict the displacement of the rebar, so that it is confined within the limited space formed between the protective cover plates 7 and the rebar bending test machine body 1, thus making it safer.

[0022] Multiple handles 8 are fixed to the upper surface of the protective cover 7, providing gripping positions and making it more convenient and quick to switch between the vertical and horizontal states of the protective cover 7.

[0023] Multiple limiting baffles 9 are fixed to the lower surface of the protective cover plate 7. The limiting baffles 9 penetrate into the gaps on the upper surface of the steel bar bending test machine body 1, thereby further restricting the flying path of the steel bar and thus making the protection effect better.

[0024] The limiting groove 4 is a shape that connects a vertical groove and an L-shaped groove. By designing the limiting groove 4 with its special shape, when the two limiting shafts 5 in the limiting groove 4 are in the vertical groove, the fixed protective cover 7 remains vertical, making it more convenient to place and remove the steel bars. Then, when the two limiting shafts 5 in the limiting groove 4 are in the L-shaped groove, the protective cover 7 remains horizontal and covers the upper surface of the steel bar bending test machine body 1, restricting the displacement of the steel bars, thereby making the bending test of the steel bars safer.

[0025] The limiting shaft 5, the protective cover plate 7, and the limiting baffle 9 are made of metal. The metal limiting shaft 5, the protective cover plate 7, and the limiting baffle 9 can generate sufficient strength to resist the danger caused by the splintering of the steel bar during the bending process, and limit the steel bar between the protective cover plate 7 and the steel bar bending test machine body 1.

[0026] Multiple countersunk holes 3 are provided on the side base 2; bolts are inserted into the countersunk holes 3 and threadedly connected to the main body 1 of the steel bar bending test machine for fixation. The countersunk holes 3 prevent the bolts from protruding from the upper surface of the side base 2 during fixation, thereby reducing the possibility of collision damage and making the fixation more stable.
