Description

Technical Field

[0001] This utility model relates to the technical field of phosphorus removal devices, specifically a mechanical phosphorus removal device for prestressed steel bars. Background Technology

[0002] The prestressed steel bar raw material has its surface iron oxide scale removed, which facilitates the straightening and drawing process in the next step. After use, it has the characteristics of clean iron oxide scale removal, straight wire outlet, and less breakage of electrical contacts.

[0003] Existing mechanical descaling devices for prestressed steel bars have a small number of descaling rollers, large spacing, and large downward pressure, resulting in unsatisfactory descaling effect. Furthermore, since the descaling rollers are integral, they need to be replaced as a whole after the surface is worn or scratched. Also, the electrical contacts are prone to breakage at the descaling point. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a mechanical descaling device for prestressed steel bars, which has the advantages of easy replacement of the descaling roller and better removal of iron oxide scale, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a mechanical descaling device for prestressed steel bars, comprising a steel plate, a controller fixedly installed on the outer wall of the steel plate, a through plate fixedly installed on the bottom outer wall of the steel plate, a cylinder fixedly installed on the top of the steel plate, a steel bar fixedly installed at the output end of the cylinder, a second descaling roller rotatably connected to the outer wall of the steel bar, a limit groove formed on the inner wall of the steel plate, a first descaling roller rotatably connected to the outer wall of the steel plate, a spring fixedly installed on the inner wall of the steel plate, a circular plate installed at one end of the spring, a fixing rod installed on the outer wall of the circular plate, a locking block fixedly installed on the outer wall of the fixing rod, a first descaling roller fixedly installed on the outer wall of the fixing rod, a steel bar slidably connected to the outer wall of the first descaling roller, and a second descaling roller fixedly installed on the outer wall of the steel bar.

[0006] As a preferred technical solution of this utility model: the controller and the cylinder are electrically connected, and the outer wall of the steel bar is slidably connected to the inner wall of the limiting groove.

[0007] As a preferred technical solution of this utility model: the number of the first dephosphorizing rollers is several, and the second dephosphorizing roller is located between the first dephosphorizing rollers.

[0008] As a preferred technical solution of this utility model: the inner wall of the steel plate is provided with a slot, and the outer wall of the slot is engaged with the outer wall of the block.

[0009] As a preferred technical solution of this utility model: the inner wall of the steel plate is provided with a sliding groove, and the outer wall of the sliding groove is adapted to the outer wall of the card block.

[0010] As a preferred technical solution of this utility model: the outer wall of the circular plate and the inner wall of the steel plate are slidably connected, and one end of the spring is fixed to the outer wall of the circular plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This mechanical descaling device for prestressed steel bars, through a control controller, uses the output end of a cylinder to drive the second descaling roller to slide up and down on the inner wall of the limiting groove via the steel bar. This allows the downward pressure of the second descaling roller on the steel bar to be adjusted. When the downward pressure is reduced, the electrical contacts are less likely to break. The number of first descaling rollers can be increased, and the second descaling roller is located between the first descaling rollers. The increased number of personnel passing through the rollers results in a better and cleaner removal of iron oxide scale from the outer wall of the steel bar, while reducing the diameter of the descaling roller.

[0013] 2. This prestressed steel bar mechanical descaling device utilizes a second descaling roller to drive a locking block to slide on the outer wall of a chute via a fixed rod. This causes the locking block to overlap and abut against the outer wall of a circular plate. The fixed rod then drives the locking block to abut against the outer wall of the circular plate, compressing the spring. The fixed rod then drives the locking block to rotate within the inner wall space of the steel plate into the locking groove, thereby ensuring the second descaling roller is stably installed on the inner wall of the steel plate. Personnel can individually replace roller rings of different diameters according to different steel wire specifications, resulting in a tighter fit, better descaling effect, and cost savings.

[0021] Please see Figures 1-5 A mechanical descaling device for prestressed steel bars includes a steel plate 1, a controller 6 fixedly installed on the outer wall of the steel plate 1, a through plate 2 fixedly installed on the bottom outer wall of the steel plate 1, a cylinder 4 fixedly installed on the top of the steel plate 1, a steel bar 7 fixedly installed at the output end of the cylinder 4, a second descaling roller 5 rotatably connected to the outer wall of the steel bar 7, a limit groove 8 formed on the inner wall of the steel plate 1, a first descaling roller 3 rotatably connected to the outer wall of the steel plate 1, a spring 9 fixedly installed on the inner wall of the steel plate 1, a circular plate 10 installed at one end of the spring 9, a fixing rod 11 installed on the outer wall of the circular plate 10, a locking block 12 fixedly installed on the outer wall of the fixing rod 11, a first descaling roller 3 fixedly installed on the outer wall of the fixing rod 11, a steel bar 7 slidably connected to the outer wall of the first descaling roller 3, and a second descaling roller 5 fixedly installed on the outer wall of the steel bar 7.

[0022] In the above structure, by installing the through plate 2, the iron oxide scale on the outer wall of the steel bar 7 is peeled off by the first dephosphorizing roller 3 and the second dephosphorizing roller 5, and the phosphorus powder falls through the through plate 2 to the bottom inner wall of the steel plate 1, which is convenient for personnel to clean.

[0023] In a preferred embodiment: the controller 6 is electrically connected to the cylinder 4, and the outer wall of the steel bar 7 is slidably connected to the inner wall of the limiting groove 8.

[0024] In the above structure, by controlling the controller 6, the output end of the cylinder 4 drives the second descaling roller 5 to slide up and down on the inner wall of the limiting groove 8 through the steel bar 7, so that the downward pressure of the second descaling roller 5 on the steel bar 7 can be adjusted. When the downward pressure is reduced, the electrical contact is less likely to break.

[0025] In a preferred embodiment, there are several first dephosphorization rollers 3, and the second dephosphorization roller 5 is located between the first dephosphorization rollers 3 and the first dephosphorization rollers 3.

[0026] In the above structure, there are several first descaling rollers 3, and the second descaling roller 5 is located between the first descaling rollers 3. The increase in the number of personnel passing through the rollers makes the iron oxide scale on the outer wall of the steel bar 7 more effectively and cleaner, and reduces the diameter of the descaling rollers.

[0027] In a preferred embodiment, the inner wall of the steel plate 1 is provided with a slot 13, and the outer wall of the slot 13 is engaged with the outer wall of the block 12.

[0028] In the above structure, the outer wall of the slot 13 is engaged with the outer wall of the block 12, and the second descaling roller 5 is used to drive the block 12 into the inner wall of the steel plate 1 through the fixing rod 11, so that the block 12 and the slot 13 are stably installed, and the second descaling roller 5 is prevented from falling off during the descaling process.

[0029] In a preferred embodiment, the inner wall of the steel plate 1 is provided with a groove 14, and the outer wall of the groove 14 is adapted to the outer wall of the block 12.

[0030] In the above structure, the second dephosphorization roller 5 drives the locking block 12 to slide on the outer wall of the slide groove 14 through the fixing rod 11, so that the locking block 12 overlaps with the outer wall of the circular plate 10 and abuts against the circular plate 10.

[0031] In a preferred embodiment, the outer wall of the circular plate 10 is slidably connected to the inner wall of the steel plate 1, and one end of the spring 9 is fixed to the outer wall of the circular plate 10.

[0032] In the above structure, the fixing rod 11 drives the locking block 12 to abut against the outer wall of the circular plate 10, so that the spring 9 is in a compressed state. The fixing rod 11 drives the locking block 12 to rotate in the inner wall space of the steel plate 1 to the slot 13, thereby making the second descaling roller 5 stably installed on the inner wall of the steel plate 1. Personnel can replace roller rings of different diameters according to different steel wire specifications, resulting in a tighter fit, better descaling effect, and cost savings.

[0033] Working principle: By controlling the controller 6, the output end of the cylinder 4 drives the second descaling roller 5 to slide up and down on the inner wall of the limiting groove 8 via the steel bar 7. This allows the downward pressure of the second descaling roller 5 on the steel bar 7 to be adjusted. Lowering the downward pressure reduces the likelihood of electrical contact breakage. With several first descaling rollers 3 passing through, and the second descaling roller 5 positioned between the first descaling rollers 3, the increased number of personnel passing through the rollers results in better and cleaner removal of iron oxide scale from the outer wall of the steel bar 7. Reducing the diameter of the descaling rollers further enhances the descaling effect. Roller 5 drives the locking block 12 to slide on the outer wall of the slide groove 14 via the fixing rod 11, so that the locking block 12 overlaps with the outer wall of the circular plate 10 and abuts against the circular plate 10. The fixing rod 11 drives the locking block 12 to abut against the outer wall of the circular plate 10, so that the spring 9 is in a compressed state. The fixing rod 11 drives the locking block 12 to rotate in the inner wall space of the steel plate 1 to the locking groove 13, thereby making the second descaling roller 5 stably installed on the inner wall of the steel plate 1. Personnel can replace roller rings of different diameters according to different steel wire specifications, resulting in a tighter fit, better descaling effect, and cost savings.
