Technical Field

[0001] The present application relates to the technical field of steel bar straightening machines, and in particular to a steel bar straightening machine. Background Art

[0002] Rebar refers to steel used for reinforced concrete and prestressed reinforced concrete. Its cross-section is circular, and sometimes square with rounded corners. It includes plain round steel bars, ribbed steel bars, and twisted steel bars. Depending on the needs, sometimes the steel bars need to be straight, and there are certain requirements for the length. At this time, a straightening machine is generally used to process the steel bars, straighten and cut the steel bars as required. Therefore, a steel bar straightening machine is particularly needed.

[0003] However, after the straightening is completed, the existing steel bar straightening machine requires workers to manually pick up the straightened steel bars and then carry them. This method is time-consuming and labor-intensive. Therefore, those skilled in the art provide a steel bar straightening machine to solve the problems raised in the above background technology. Utility Model Content

[0004] In order to solve the problems raised in the above background technology, the present application provides a steel bar straightening machine.

[0005] The present application provides a steel bar straightening machine that adopts the following technical solution:

[0006] A steel bar straightening machine comprises a machine body, wherein lower straightening rollers are provided at equal intervals horizontally at the front end of the machine body, and a plurality of upper straightening rollers are provided above the lower straightening rollers, a blanking assembly is provided on one side of the machine body, and the blanking assembly comprises an inclined table, a rectangular groove is provided at the upper end of the inclined table, a rotating motor is fixedly mounted on the inner wall of one side of the rectangular groove, a blocking rod is fixedly mounted on one end of the output shaft of the rotating motor, a supporting leg is fixedly mounted on the lower end of the inclined table, an L-shaped plate is fixedly mounted on the outside of the supporting leg, an arc plate is fixedly mounted on the upper end of the L-shaped plate, an electric push rod is fixedly mounted on one side of the L-shaped plate, and a contact plate is fixedly mounted on one end of the electric push rod.

[0007] Preferably, the lower straightening roller and the upper straightening roller are both driven by motors.

[0008] Preferably, a fixing plate is fixedly installed on one side of the machine body, a rectangular through slot is opened on one side of the fixing plate, and two telescopic cylinders are fixed through the upper and lower inner walls of the rectangular through slot.

[0009] Preferably, an upper pressing plate is fixedly installed on the top of the two telescopic cylinders located at the lower end, and a lower pressing plate is fixedly installed on the top of the two telescopic cylinders located at the upper end.

[0011] To sum up, the present application includes the following beneficial technical effects: through the setting of the unloading assembly, the baffle can block the falling of the steel bars. When the straightened steel bars accumulate to a certain extent, the rotating motor is started to rotate the baffle to the inside of the rectangular groove. At this time, the straightened steel bars fall onto the arc plate at the upper end of the L-shaped plate. At this time, since one end of the fallen steel bars is not aligned, the electric push rod is started to move the contact plate, so that one end of multiple steel bars is aligned and placed, which is convenient for later bundling and makes the straightening efficiency higher.

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0017] like Figure 1-Figure 3As shown, a steel bar straightening machine includes a machine body 1. The front end of the machine body 1 is horizontally and equidistantly provided with lower straightening rollers 2, and a plurality of upper straightening rollers 3 are arranged above the lower straightening rollers 2. A blanking assembly 4 is provided on one side of the machine body 1. The blanking assembly 4 includes an inclined platform 41. A rectangular groove 42 is formed at the upper end of the inclined platform 41. A rotating motor 49 is fixedly mounted on the inner wall of one side of the rectangular groove 42. A stopper 43 is fixedly mounted on one end of the output shaft of the rotating motor 49. A support leg 44 is fixedly mounted on the lower end of the inclined platform 41. An L-shaped plate 45 is fixedly mounted on the outside of the support leg 44. An arc-shaped plate 46 is fixedly mounted on the upper end of the L-shaped plate 45. An electric push rod 47 is fixedly mounted on one side of the L-shaped plate 45. A contact plate 48 is fixedly mounted on one end of the electric push rod 47. The lower straightening roller 2 and the upper straightening roller 3 are both driven by a motor.

[0018] First, the bent steel bar is placed between the lower straightening roller 2 and the upper straightening roller 3 for straightening. The straightened steel bar will fall onto the inclined platform 41. Figure 1 In the position shown, the blocking rod 43 can stop the falling of the steel bars. When the straightened steel bars accumulate to a certain level, the rotating motor 49 is started to rotate the blocking rod 43 to the inside of the rectangular groove 42. At this time, the straightened steel bars fall onto the arc plate 46 at the upper end of the L-shaped plate 45. At this time, since one end of the fallen steel bars is not aligned, the electric push rod 47 is started to move the contact plate 48, so that one end of multiple steel bars are aligned and placed, which is convenient for later bundling.

[0019] A fixed plate 5 is fixedly mounted on one side of the machine body 1. A rectangular slot 6 is defined on one side of the fixed plate 5. Two telescopic cylinders 7 are fixedly mounted on the upper and lower inner walls of each of the rectangular slots 6. An upper pressure plate 8 is fixedly mounted on the tops of the two telescopic cylinders 7 at the lower end, while a lower pressure plate 9 is fixedly mounted on the tops of the two telescopic cylinders 7 at the upper end. The tops of the rectangular slots 6 are also fixedly mounted between the two lower pressure plates 9. A high-speed motor 10 is mounted on the outside of the telescopic cylinders 7, with a cutting blade 11 fixedly mounted on one end of the output shaft of the high-speed motor 10.

[0020] Since thin steel bars are long during production and inconvenient to place later, after the straightened steel bars pass through the rectangular through slot 6, the upper pressure plate 8 and the lower pressure plate 9 at the upper end of the telescopic cylinder 7 move simultaneously to limit the steel bars, the high-speed motor 10 rotates, and the cutting knife 11 quickly cuts the thin steel bars. The cut steel bars meet actual needs and are convenient for later cutting and bundling.

[0021] The implementation principle of the steel bar straightening machine of the embodiment of the present application is as follows: first, the bent steel bar is placed between the lower straightening roller 2 and the upper straightening roller 3 for straightening. The straightened steel bar will fall onto the inclined table 41. Figure 1In the position shown, the blocking rod 43 can stop the falling of the steel bars. When the straightened steel bars accumulate to a certain level, the rotating motor 49 is started to rotate the blocking rod 43 to the inside of the rectangular groove 42. At this time, the straightened steel bars fall onto the arc plate 46 at the upper end of the L-shaped plate 45. At this time, since one end of the fallen steel bars is not aligned, the electric push rod 47 is started to move the contact plate 48 so that one end of multiple steel bars are aligned and placed, which is convenient for later bundling. Since the thin steel bars are longer during production, it is not convenient to place them later. After the straightened steel bars pass through the rectangular through groove 6, the upper pressure plate 8 and the lower pressure plate 9 at the upper end of the telescopic cylinder 7 move at the same time to limit the steel bars. The high-speed motor 10 rotates, and the cutting knife 11 quickly cuts the thin steel bars. The cut steel bars meet actual needs and are convenient for later unloading and bundling.
