[0026] Please refer to Figures 1 to 5 The physical scale test equipment for the oxide scale is described as follows. The physical scale test equipment for the oxide scale comprises a test table 1, a bending angle seat 2, a rotating strip plate 3, a torsion seat 4 and a torsion sleeve 5. The bending angle seat 2 and the torsion seat 4 are arranged on the test table 1. One end of the rotating strip plate 3 is hinged to the driving rod test table 1 through a limiting column 31 extending in the up-down direction, and the other end is provided with a driving rod 32. A forming shaft 33 is arranged on the rotating strip plate 3 adjacent to the limiting column 31 to bend the disc strip 8 in cooperation with the limiting column 31. The forming shaft 33 and the limiting column 31 abut against two sides of the disc strip 8 respectively to make the disc strip 8 bend around the limiting column 31 and form a bend 81. The torsion seat 4 is provided with a jacking piece 41 for pressing the limiting disc strip 8. The torsion sleeve 5 is used for being sleeved on the bend 81 of the disc strip 8 to torsionally twist the disc strip 8 or for being sleeved on the driving rod 32 to drive the rotating strip plate 3 to swing horizontally.
[0027] Compared with the prior art, the physical scale test equipment for the oxide scale provided in the embodiment utilizes the bending angle seat 2 to limit the end of the disc strip 8. The driving rod 32 drives the rotating strip plate 3 to rotate around the limiting column 31. The forming shaft 33 above the rotating strip plate 3 and the limiting column 31 cooperate with each other to bend the disc strip 8 to form the bend 81. Then the jacking piece 41 is used to lock the bend 81 on the torsion seat 4. The torsion sleeve 5 is used to torsionally twist the disc strip 8, which facilitates the effective peeling of the oxide scale on the outer periphery of the disc strip 8, so as to directly observe the outer wall of the disc strip 8. The equipment improves the convenience of test operation, ensures the accuracy of disc strip 8 detection, and improves the operation efficiency of the test.
[0028] The test device is used in the process, the wire rod 8 is affected by the torsion and produces controllable plastic deformation, because the deformation of the oxide skin formed on the surface of the wire rod 8 is small, therefore, after the axial displacement is generated, the oxide skin on the surface of the wire rod 8 can be effectively peeled off, and the test device is suitable for detecting the wire rod product with a diameter of 5.5-9mm.
[0029] In the embodiment, the torsion sleeve 5 can be used for the subsequent torsion operation of the wire rod 8, and can be sleeved on the driving rod 32 during the bending of the wire rod 8, so as to facilitate the driving of the driving rod 32 to drive the rotating strip plate 3 to rotate around the limiting column 31, facilitate the increase of the force arm, reduce the force applied by the operator, and have good labor-saving effect.
[0030] In a possible implementation, please refer to Figures 1 to 5 The bending angle seat 2 includes a first plate body 21 and a second plate body 22, the first plate body 21 and the second plate body 22 are arranged at a right angle, the inner side wall of the first plate body 21 is used for limiting the end face of the wire rod 8, and the second plate body 23 is used for limiting the peripheral wall of the wire rod 8.
[0031] In the embodiment, when the unbent rod-shaped wire rod 8 is installed to the bending angle seat 2, the end face of the wire rod 8 is in contact with the inner side wall of the first plate body 21, the end of the wire rod 8 is limited, the bending size of the elbow 81 is guaranteed to be consistent, and the second plate body 22 limits the peripheral wall of the wire rod 8 (specifically, the peripheral wall of the elbow 81 which is bent subsequently), then the limiting column 31 is pressed against one side of the peripheral wall of the wire rod 8 by driving the rotating strip plate 3 to swing horizontally, so that the corresponding position of the wire rod 8 is limited in position, and the wire rod 8 is driven to bend by the forming shaft 33, so that the end part adjacent to the bending angle seat 2 of the wire rod 8 is formed into the elbow 81.
[0032] Specifically, the first plate body 21 and the second plate body 22 are integrally formed, which can enhance the connection strength between the two, guarantee the effective limitation of the end and the peripheral wall of the wire rod 8, and meet the bending requirement of the elbow 81.
[0033] In a possible implementation, please refer to Figures 1 to 5 The main shaft of the driving rod 32 extends along the tangent direction of the limiting column 31, the driving rod 32 has an extension part 34 which protrudes outward from the side edge of the rotating strip plate 3, and the torsion sleeve 5 is sleeved on the extension part 34. The above-mentioned mode is convenient for driving the driving rod 32, which is helpful to reduce the force arm and realize the labor-saving effect. By sleeving the torsion sleeve 5 on the driving rod 32, the driving effect of the rotating strip plate 3 is realized.
[0034] Further, in order to avoid the interference of the corner position of the test bench 1 to the operation of the operator to the torsion sleeve 5, the corner of the test bench 1 is chamfered to realize sufficient avoidance of the structure.
[0035] In a possible implementation, please refer toFigures 1 to 5 A rolling sleeve 37 is sleeved on the limiting column 31, and the rolling sleeve 37 is in rolling cooperation with the peripheral wall of the coil rod 8.

[0036] In some embodiments, referring to Figures 1 to 5 The end of the rotating strip plate 3 away from the limiting column 31 is also provided with a reinforcing part 35, and the reinforcing part 35 is located on the side away from the extending part 34. The reinforcing part 35 at the end of the rotating strip plate 3 facilitates structural reinforcement of the rotating strip plate 3, ensures the installation strength of the driving rod 32, and meets the strength requirement of subsequent driving.
[0037] Further, the driving rod 32 can also be driven by a hydraulic cylinder or other power element, reduces the labor intensity of manual operation, improves the automation degree of the equipment, and expands the specification range of the coil rod 8.

The rolling bearings 36 can form a rolling action with the peripheral wall of the coil rod 8, can reduce the friction action between the rolling bearings 36 and the coil rod 8, avoids affecting the oxide skin on the peripheral wall of the coil rod 8 in the forming process of the coil rod 8, and ensures the test precision in the subsequent process.
[0039] Further, in order to ensure the effective contact between the rolling bearings 36 and the coil rod 8, two or more rolling bearings 36 can be sleeved on the outer periphery of the forming shaft 33 to form a stacked structure, so as to avoid the influence of the up-and-down shaking of the coil rod 8 on the bending process.
[0040] In a possible implementation, referring to Figures 1 to 5 The outer periphery of the limiting column 31 is provided with an outwardly protruding accommodation boss 38, and the accommodation boss 38 is located between the test table 1 and the rotating strip plate 3.
[0041] In this embodiment, in order to facilitate driving of the driving rod 32, the lower part of the limiting column 31 can be provided with the accommodation boss 38 which is supported below the rotating strip plate 3, so as to leave sufficient distance in the up-and-down direction and facilitate subsequent installation of the torsion sleeve 5 on the driving rod 32.
[0042] In a possible implementation, referring to Figures 1 to 5 The side wall of the torsion seat 4 is provided with a side limiting hole 42 for accommodating the elbow 81, and the jacking piece 41 extends into the side limiting hole 42 through the top wall of the torsion seat 4 and is used for abutting against the peripheral wall of the elbow 81.
[0043] In the embodiment, the elbow 81 is inserted into the side limiting hole 42 of the torsion seat 4, and the top pressing piece 41 is used to press against the circumferential wall of the elbow 81, so that the elbow 81 is effectively locked. The top pressing piece 41 can be a top pressing screw or the like, which can effectively lock the elbow 81 and facilitate the subsequent twisting operation of the wire rod 8.
[0044] In some embodiments, referring to Figures 1 to 5 , the test bench 1 is provided with a limiting plate 6 adjacent to the torsion seat 4 and extending in the up-down direction. The side of the limiting plate 6 is provided with a limiting cavity 61 for the wire rod 8 to pass through. The limiting plate 6 is provided with a limiting pin 62 extending into the limiting cavity 61 to limit the wire rod 8. After the elbow 81 is installed into the side limiting hole 42, the wire rod 8 can be placed in the limiting cavity 61 of the limiting plate 6. The limiting cavity 61 extends to one side edge of the limiting plate 6, which facilitates the installation of the wire rod 8. Then, the wire rod 8 is limited in the limiting cavity 61 by the limiting pin 62, so as to limit the wire rod 8 in the subsequent twisting process and facilitate the judgment of the peeling of the iron oxide skin of the wire rod 8.
[0045] In a possible implementation, referring to , the test bench 1 is further provided with a supporting seat 7. The bending angle seat 2, the rotating strip plate 3, and the torsion seat 4 are all arranged on the supporting seat 7. The test bench 1 has a collection area 12 located below the outside of the supporting seat 7.
[0046] In the embodiment, the test bench 1 is provided with the supporting seat 7. The bending angle seat 2, the rotating strip plate 3, and the like are all installed on the supporting seat 7. The side limiting hole 42 of the torsion seat 4 faces the outside of the supporting seat 7. When the wire rod 8 is twisted subsequently, the iron oxide skin can fall into the collection area 12 of the test bench 1, which facilitates the centralized collection of the iron oxide skin and helps to judge the peeling condition of the iron oxide skin.
[0047] The above-mentioned iron oxide skin physical peeling test equipment drives the rotating strip plate 3 to rotate around the limiting column 31 by the driving rod 32. The end of the wire rod 8 is limited by the bending angle seat 2, and the forming shaft 33 above the rotating strip plate 3 bends the wire rod 8 to form the elbow 81. Then, the elbow 81 is locked on the torsion seat 4 by the top pressing piece 41. The wire rod 8 is twisted by the torsion sleeve 5, which facilitates the effective peeling of the iron oxide skin on the outer periphery of the wire rod 8, so as to directly observe the outer wall of the wire rod 8. The equipment improves the convenience of the test operation, ensures the accuracy of the detection of the wire rod 8, and improves the operation efficiency of the test.
