Description

Technical Field

[0001] This utility model relates to the technical field of testing for reinforcing bar bending tests, and in particular to a testing device for reinforcing bar bending tests. Background Technology

[0002] A rebar bending machine is a processing tool for bending rebar. Rebar processing is essential in the construction and industrial fields. With the rapid development of industry and construction, our rebar processing volume is also increasing. Bending rebar is generally the most important processing method, so we have rebar bending machines.

[0003] Among existing testing devices for rebar bending tests, such as the one disclosed in utility model patent application number 202021616869.6, this utility model, through the setting of universal wheels, enables the rebar bending test device to move freely. The device, through the setting of a first motor and a bending disc, enables it to bend rebar. Through the cooperation of a limiting plate and a clamping plate, the rebar being tested can be fixed during use, thereby reducing the need for manual fixing.

[0004] However, during the testing process for rebar bending tests, the rebar will experience friction and bends in multiple directions during use, requiring testing. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a steel bar bending test device that, by setting a moving mechanism and a bending mechanism, can simulate the actual use of materials during the steel bar bending test, has a large testing range, and good testing effect.

[0006] The present invention provides a testing device for a steel bar bending test, comprising a limiting mechanism; and further comprising two sets of clamping mechanisms, two sets of moving mechanisms, two sets of driving mechanisms and two sets of bending mechanisms. The two sets of clamping mechanisms are mounted on the limiting mechanism, the two sets of moving mechanisms are mounted on the limiting mechanism, the two sets of driving mechanisms are mounted on the limiting mechanism, and each set of moving mechanisms is equipped with a set of bending mechanisms.

[0007] The limiting mechanism limits the material, the clamping mechanism clamps it, the moving mechanism moves it, the driving mechanism drives it, and the bending mechanism bends it. By opening the limiting mechanism to limit the material, the clamping mechanism to clamp it, the bending mechanism to bend it, and the driving mechanism to drive it, the bending mechanism to move it and simulate friction, thus simulating the actual use of the material during the steel bar bending test, resulting in a large testing range and good testing effect.

[0008] Preferably, the limiting mechanism includes a base, two sets of limiting blocks, a bidirectional lead screw, and a motor. The two sets of limiting blocks are slidably mounted on the base, and the bidirectional lead screw is rotatably mounted on the base. The bidirectional lead screw and the two sets of limiting blocks are threaded together. The motor is mounted on the left end of the base, and the output end of the motor is connected to the input end of the bidirectional lead screw. By turning on the motor, the bidirectional lead screw is driven to rotate. As the bidirectional lead screw rotates, it engages with the limiting blocks through the threaded connection, causing the limiting blocks to move and limit the material movement.

[0009] Preferably, the clamping mechanism includes a jaw and a threaded sleeve. The jaw is mounted on a limiting block, and the threaded sleeve is mounted on the jaw via threads. By rotating the threaded sleeve to engage with the jaw, the threaded sleeve moves, thereby tightening the jaw and clamping the material.

[0010] Preferably, the moving mechanism includes a threaded block and a lead screw. The threaded block is slidably mounted on the base, and the lead screw is rotatably mounted on the base, with the lead screw and the threaded block being threadedly engaged. The threaded block is moved by rotating the lead screw and engaging with it.

[0011] Preferably, the drive mechanism includes a worm gear, a second motor, and a worm. The worm gear is connected to the input end of the lead screw. The second motor is installed on the right end of the base. The input end of the worm is connected to the output end of the second motor, and the worm and the worm gear perform worm gear transmission. By turning on the second motor, the worm is driven to rotate. While the worm is rotating, it performs worm gear transmission with the worm gear, causing the worm gear to drive the lead screw to rotate.

[0012] Preferably, the bending mechanism includes a hydraulic cylinder and a contact wheel. The hydraulic cylinder is mounted on the threaded block, and the contact wheel is rotatably mounted on the hydraulic cylinder. By opening the hydraulic cylinder, the contact wheel contacts the material, thereby bending the material.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: by opening the limiting mechanism to limit the material, by opening the clamping mechanism to clamp the material, by opening the bending mechanism to bend the material, by opening the driving mechanism to drive, and by opening the bending mechanism to simulate friction, the material can be simulated under actual use conditions during the steel bar bending test, resulting in a large testing range and good testing effect.
