Description

Technical Field

[0001] The utility model relates to the technical field of the pressing rib experiment of galvanized iron wire, in particular to a straightening and pressing rib test device for galvanized iron wire.

[0002] Background Technique

[0003] As a common building material, steel bars play an important role in concrete structures. In order to

[0004] better understand and apply the role of steel bars in concrete structures, researchers usually use

[0005] galvanized iron wires with similar properties to simulate steel bars in model tests.

[0006] However, in current projects, ribbed steel bars are basically used, while the surface of galvanized iron wire is smooth. If galvanized iron wire is directly used,

[0007] it is very difficult to simulate the bonding and slip effects between steel bars and concrete in actual projects. Therefore, there is an urgent need

[0008] to design a device to straighten and press ribs on galvanized iron wire to produce more realistic test effects.

[0009] In the prior art, the invention with the patent number CN116735345A discloses a test device for straightening and pressing ribs on galvanized iron wire. Since the surface of galvanized iron wire is smooth, a device needs to be developed to straighten and press ribs on it in order to

[0010] produce realistic test effects. In this invention, a straightening roller assembly is provided on the base, and the straightening roller assembly includes

[0011] two rows of small rollers, upper and lower; a lower pressing rib roller assembly is also provided on the base, and an upper pressing rib roller assembly is provided above it. The lower pressing rib roller assembly has lower rollers, and the upper pressing rib roller assembly has upper rollers. The lower rollers are connected to the motor

[0012] ; Insert the galvanized iron wire into the groove between the upper roller and the lower roller from the side without small rollers, and continue

[0013] to insert it between the upper and lower small rollers. After the galvanized iron wire passes through from the other side, rib marks can be pressed out and it can be

[0014] straightened from a coil of galvanized iron wire. This invention can press ribs and straighten galvanized iron wire to promote

[0015] the test to produce more practical data and effects.

[0018] However, in order to adapt to rib pressing of galvanized iron wires with different diameters, the above technology requires continuous

[0019] dismantling and installing the upper roller to adjust the distance between the upper roller and the lower roller, making the rib pressing process

[0020] troublesome. Therefore, it needs to be optimized and improved. Content of the Utility Model

[0021] According to the above existing technical problems, the utility model provides a straightening and rib pressing test device for galvanized iron wires,

[0022] which can realize the downward movement of the upper roller by operating the sheep's horn nut, and further realize the adjustment of the distance between the upper roller and the lower roller, with convenient operation.

[0072]

[0073] Embodiment 1

[0074] As shown in the figure, two lower mounting blocks 21 in the lower pressing roller assembly are fixed to the bottom plate 1 by screws. A lower roller 22 is installed between the two lower

[0075] mounting blocks 21 through bearings. One end of the lower roller 22 is connected to the output end of the driving motor 25 through a rotating shaft 24. The driving motor 25 is installed on the bottom plate 1 through a mounting seat 251. The two ends of the lower mounting block

[0076] 21 are respectively connected to fixing blocks 43. A stud 31 is connected to the fixing block 43. The upper end of the stud 31 passes through and extends out of the through hole provided on the upper mounting

[0077] block 31 and is threadedly connected to a split nut 42. A support spring 44 is provided between the fixing block 43 and the upper mounting block 31. The support spring 44 is located outside the stud 41. Two upper mounting

[0078] blocks 31 are installed with an upper roller 32 through bearings. The upper roller 32 is located directly above the lower roller 22, and

[0079] roller grooves 23 are provided at the middle positions of both the upper roller 32 and the lower roller 22 for ribbing the galvanized iron wire.

[0080] A guiding component is arranged at the front side position of the lower roller 22 on the bottom plate 1. The guiding component consists of a support column 51

[0081] and a guiding ring 52. The support column 51 is installed on the bottom plate 1. A guiding ring 52 is provided at the top end of the support column 51, and the guiding ring 52 is opposite to the position where the roller groove 23 is provided.

[0082]

[0083]

[0084] Specifically, an installation plate 6 is arranged between two upper installation blocks 32, and a spirit level 7 is installed on the installation plate 6,

[0085] which is used to observe whether the two upper installation blocks 32 are on the same horizontal plane after adjustment.

[0086] Embodiment 2

[0087] When using the present utility model, the distance between the upper roller 32 and the lower roller 22 is adjusted according to the diameter of the galvanized iron wire. The upper installation block 31 for installing the upper roller 32 is supported by a support spring 44,

[0088] so that it is located above the lower roller 22. When adjusting the distance, by operating the sheep's horn nut 42 on the stud 41,

[0089] the sheep's horn nut 42 moves downward, which will give the upper installation block 31 a downward pressure, and the support spring 44 is further compressed.

[0090] Then the upper installation block 31 will move downward, so that the position of the upper roller 32 moves downward, thereby realizing the adjustment of the distance between the upper roller 32 and the lower roller 22. There is no need to repeatedly disassemble and install, making the adjustment operation convenient, and

[0091] whether the two upper installation blocks 31 at both ends are on the same horizontal plane after adjustment can be observed by the spirit level 7. It should be noted that the spirit level 7 is an existing instrument for measuring the horizontal level, so it will not be elaborated in detail in this application.

[0092] After adjustment, the operator passes one end of the galvanized iron wire through the guiding ring 52 and extends it between the upper roller 32 and the lower roller 22,

[0093] and then starts the driving motor 25. The driving motor drives the lower roller 22 to rotate, and ribs are pressed on the galvanized iron wire through the roller groove 23. The galvanized iron wire after rib pressing can better simulate

[0094] the bond slip and other effects between the steel bar and the concrete in the actual project during the experiment, so as to promote the experiment to generate more practical data and effects.
