Description

Technical Field

[0001] This utility model relates to the field of steel bar straightening technology, and more specifically, to an integrated machine for straightening and removing rust from steel bars. Background Technology

[0002] A rebar straightening machine mainly uses a series of mechanical devices to straighten bent rebars. Its core principle is to use the friction between the rebar and the straightening device to make the rebar move forward. At the same time, as it passes through the straightening device, it is subjected to repeated bending and stretching, thereby straightening the bent rebar.

[0003] When steel bars are placed outdoors, they will be bent under pressure, and the high humidity in the open air makes them prone to rusting, making them unsuitable for direct use as they pose a safety hazard. Conventional steel bar straightening machines cannot completely remove the rust from the steel bars, causing them to rust easily even after straightening. Therefore, a steel bar straightening and rust removal integrated machine was designed to solve this problem. Utility Model Content

[0004] The purpose of this utility model is to provide a steel bar straightening and rust removal integrated machine with both straightening and rust removal functions, and with more thorough rust removal.

[0005] This utility model is achieved through the following technical solution: a rebar straightening and rust removal integrated machine, comprising a traction mechanism, a straightening mechanism and a rust removal mechanism arranged in sequence. The straightening mechanism includes a rotating drum and straightening wheels, and multiple straightening wheels are evenly arranged in the inner wall of the rotating drum. The rust removal mechanism includes a cylinder cover and wire brushes. The wire brushes are symmetrically arranged on both sides of the cylinder cover, and the tail end of the wire brush is provided with a first spring connected to the cylinder cover. The rebar passes through the gap between the two wire brushes. A blower is provided on the top of the cylinder cover.

[0006] Furthermore, the outside of the rotating drum is provided with a gear ring, which is meshed with a drive gear, and the drive gear is connected to a first power motor; a mounting cavity is provided below the straightening mechanism, and the drive gear and the first power motor are located in the mounting cavity; bearings are fitted at both ends of the rotating drum.

[0007] Furthermore, the traction mechanism includes a group of guide rollers arranged vertically, and the surface of the guide rollers is provided with a number of breaking protrusions.

[0008] Furthermore, the guide rollers are provided with at least two sets arranged side by side, and the lower end of the guide rollers is provided with pulleys, with belts sleeved between the pulleys, and one of the guide rollers is connected to a second power motor for driving.

[0009] Furthermore, the traction mechanism has a guide cylinder at its front end, and the guide cylinder is set in a horizontal position.

[0010] Furthermore, the bottom of the shroud is provided with a discharge port, which is located below the wire brush, and a receiving bucket is provided below the discharge port.

[0011] Furthermore, the wire brush has a crescent-shaped structure.

[0012] The technical solution of this utility model has at least the following advantages and beneficial effects: This utility model removes rust simultaneously during the straightening process of the steel bars. The rotation combined with the wire brush during the straightening process helps to clean the rust on the surface of the steel bars more thoroughly. At the same time, the blower prevents rust from adhering and also dries the surface of the steel bars, making them less prone to secondary rusting. Attached Figure Description

Detailed Implementation

[0017] The following description, in conjunction with specific embodiments, provides further details. Figures 1-3As shown, this embodiment is an integrated machine for straightening and removing rust from reinforcing bars, including a traction mechanism 1, a straightening mechanism 2, and a rust removal mechanism 3 arranged sequentially. The straightening mechanism 2 includes a rotating drum 21 and straightening wheels 22, with multiple straightening wheels 22 evenly arranged on the inner wall of the rotating drum 21. The rust removal mechanism 3 includes a cylinder cover 31 and wire brushes 32, with the wire brushes 32 symmetrically arranged on both sides of the cylinder cover 31. The tail end of each wire brush 32 is provided with a first spring 321 connected to the cylinder cover 31. The reinforcing bar passes through the gap between the two wire brushes 32. The top of the cylinder cover 31 is provided with... Hair dryer 33; Specifically, the reinforcing bar is introduced and moved by the traction mechanism 1, and then rotated and straightened by the rotating drum 21 and straightening wheel 22 of the straightening mechanism 2. Then, through the rust removal mechanism 3, the rotating reinforcing bar comes into frictional contact with the wire brush 32. The wire brush 32 scrapes off the rust on the surface of the reinforcing bar, and the hair dryer 33 located above can blow air at the position where the wire brush 32 is applied, preventing rust from adhering. At the same time, it can dry the reinforcing bar, preventing moisture from remaining on the surface of the reinforcing bar and reducing the speed of secondary rusting. Its cleaning effect is good.

[0018] like Figure 1 As shown, in this embodiment, the rotating drum 21 is provided with a gear ring 23 on its outside, and the gear ring 23 is meshed with a drive gear 25. The drive gear 25 is connected to a first power motor 26. The straightening mechanism 2 is provided with a mounting cavity 5 below it, and the drive gear 25 and the first power motor 26 are located in the mounting cavity 5. Bearings 24 are fitted at both ends of the rotating drum 21. Specifically, the rotating drum 21 is driven by the first power motor 26 to rotate the drive gear 25, and the drive gear 25 drives the gear ring 23 and the rotating drum 21 to rotate together.

[0019] like Figure 1 and Figure 3 As shown, the traction mechanism 1 in this embodiment includes a group of guide rollers 11 arranged vertically, and the surface of the guide rollers 11 is provided with a number of crushing protrusions 111. Specifically, the guide rollers 11 pull the steel bars for horizontal movement and conveying, and the steel bars are sandwiched between two guide rollers 11. The crushing protrusions 111 can increase the contact friction to avoid slippage, and can also crush and remove the relatively soft soil and rust on the surface of the steel bars, reducing the difficulty of subsequent processing.

[0020] In addition, the guide rollers 11 are provided with at least two sets arranged side by side, and the lower end of the guide rollers 11 is provided with pulleys 12. A belt 13 is sleeved between multiple pulleys 12. One of the guide rollers 11 is connected to a second power motor 14 for driving. Specifically, multiple sets of guide rollers 11 are driven by a single second power motor 14 to make their rotation speed consistent.

[0021] When the reinforcing bar is inserted, a guide cylinder 4 is provided at the front end of the traction mechanism 1, and the guide cylinder 4 is set in a horizontal state to prevent the reinforcing bar from shifting.

[0022] like Figure 1As shown, a discharge port 311 is provided at the bottom of the cylinder cover 31. The discharge port 311 is located on the lower side of the wire brush 32, and a receiving bucket 34 is provided below the discharge port 311. Specifically, the cylinder cover 31 is located below the wire brush 32 and has a conical funnel-shaped discharge port 311 to facilitate the recycling of the removed rust.

[0023] like Figure 2 As shown, in order to improve the fit and coverage of the wire brush 32 with the reinforcing bar, the wire brush 32 is designed as a crescent-shaped structure.

[0024] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
