[0002] At present, the bending machines on the domestic market are mainly used to meet the bending angle requirements of bent parts, facilitate the replacement of bending part molds, and reduce the labor intensity of workers. According to different functional requirements in different fields, the structures of bending machines are also different. The main purpose is to change the wire bending from manual operation to mechanical operation.

[0003] Steel wires are widely used in the construction field and can be used to reinforce concrete structures and improve the seismic performance of buildings. Their high strength and corrosion resistance make them ideal building materials. Steel wires can also be used to manufacture mechanical equipment, auto parts, etc. Their excellent mechanical properties and wear resistance make them widely used in the manufacturing industry. Steel wires can also be used to manufacture wires and cables. Their electrical conductivity and high temperature resistance make them important materials in the fields of power transmission and communication. Steel wires have some other applications, such as making springs and making wire ropes. In short, steel wires have a variety of uses and are widely used in fields such as construction, manufacturing, and power transmission.

[0004] At present, most of the same type of wires at home and abroad adopt general wire bending machines or manual bending to achieve the required product shapes and dimensions. For a general numerical control wire bending machine, it costs 200,000 to 300,000 yuan per unit, and special programming and operating personnel are required, so the equipment and production costs are relatively high. Therefore, when general factories are in production, they often bend wires manually. This method greatly increases the labor intensity of workers, resulting in low production efficiency, poor bending quality, inconsistent shapes of the bent products, unstable wire quality, and is not suitable for modern industrial production. Content of the Utility Model

[0005] The purpose of the utility model is to provide an electric bending device for steel wires. In the whole processing process of the steel wire, only the position of the steel wire needs to be placed manually, and it is limited and fixed by a wire contact plug and a wire limit plug, and then the driving motor is started to achieve the bending effect of the steel wire. The overall bending process is simple and convenient to operate, and the motor is used as the bending power, so the bending effect is better and the efficiency is higher.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: an electric bending device for steel wires, comprising: a bending turntable, a turntable support mechanism, a wire fixing mechanism, and a wire front-position supporting mechanism;

[0007] The turntable support mechanism includes a support base, a support column, and a support platform, wherein the top and bottom ends of the support column are fixedly connected to the bottom surface of the support platform and the top surface of the support base respectively; a drive motor is fixedly arranged on the top surface of the support platform, and a rotor end of the drive motor is fixedly connected to the rear side of the bending turntable;

[0008] The wire fixing mechanism is fixedly arranged on the outer side of the circumference of the bending turntable, and the wire fixing mechanism includes a wire fixing seat and a wire contact plug.

[0009] The wire front support mechanism includes a support thick plate, which is arranged on the wire inlet side of the bending turntable. The support thick plate is provided with a transversely penetrating support opening on the front side corresponding to the position of the wire opening, and a wire limiting plug is provided in the support opening.

[0010] As a preferred technical solution of the utility model, the bottom end of the supporting thick plate is vertically fixedly connected to the top surface of the supporting base.

[0011] As a preferred technical solution of the utility model, at least two groups of bending turntables are provided, and the centers of the multiple bending turntables are arranged on the rotor end axis of the drive motor. The bending turntable with the largest diameter is closest to the drive motor. The bending turntables are arranged in sequence from large to small in diameter along the direction away from the drive motor, and adjacent bending turntables are fixedly connected.

[0012] As a preferred technical solution of the utility model, the bending mounting seat is provided with a sunken groove at the bottom corresponding to the innermost part of the wire opening, and the sunken groove is used to accommodate the steel wire to be bent.

[0016] In summary, the utility model has the following beneficial effects: Due to the physical properties of steel itself, it is very difficult to manually bend it. Therefore, the utility model uses a driving motor for bending drive, and at the same time uses a bending turntable as the bending abutment die for steel wire, realizing the automatic bending of steel wire. During the actual use of steel wire bending, the steel wire is passed through the supporting opening and the wire opening in sequence, and then a wire abutting plug is inserted into the wire opening to fix one end of the wire. A wire limiting plug is inserted into the supporting opening to prevent the wire from slipping out of the supporting opening, so that the steel wire is placed on the bending turntable and the supporting thick plate.

Detailed implementation manners

[0025] To make the purpose, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Therefore, the following detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the claimed present utility model, but merely represents the selected embodiments of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0026] As Figures 1-7 shown, the present utility model provides an electric bending device for steel wire, including: a bending turntable 1, a turntable support mechanism, a wire fixing mechanism and a wire front-position supporting mechanism;

[0027] As Figure 2 shown, the turntable support mechanism includes a support base 2, a support column 3, and a support table 4. The top and bottom ends of the support column 3 are respectively fixedly connected to the bottom surface of the support table 4 and the top surface of the support base 2; a drive motor 5 is fixedly arranged on the top surface of the support table 4, and the rotor end of the drive motor 5 is fixedly connected to the rear side of the bending turntable 1; wherein the drive motor 5 is provided with a control switch for controlling the working rotation of the drive motor 5, including the rotation angle and rotation speed, so as to be able to control the bending amplitude of the steel wire. The turntable support mechanism is used to support the drive motor 5 and the bending turntable 1. During the actual driving of the bending turntable 1, a large reaction force will be generated. Therefore, a bearing is also arranged on the support table 4, wherein the outer ring of the bearing is fixedly connected to the support table 4 for supporting the bending turntable 1, and the inner ring of the bearing is fixedly connected to the side of the bending turntable 1 where the rotor end of the drive motor 5 is connected. When the rotor end of the drive motor 5 acts, it can drive the inner ring of the bearing to rotate, that is, it can drive the bending turntable 1 to rotate.

[0028] As Figure 1 and 4 shown, the wire fixing mechanism is fixedly arranged on the outer circumference of the bending turntable 1. The wire fixing mechanism includes a wire fixing seat 6 and a wire contact plug 7. As Figure 5As shown, a wire opening 8 which runs transversely through the front side of the wire fixing seat 6 is provided, and a wire contact plug 7 is provided in the wire opening 8 for contacting and connecting the steel wire; when the steel wire is fixed by the wire contact plug 7, the driving motor 5 is started to rotate, which can drive the steel wire to move downward away from the supporting thick plate 9. At this time, the steel wire is limited by the outer circumference of the bending turntable 1, thereby bending occurs.

[0029] like Figure 3 As shown, the front support mechanism of the wire includes a support plate 9, the bottom end of which is vertically fixedly connected to the top surface of the support base 2, so that the distance between the support plate 9 and the support column 3 is fixed, so that the wire has better movement stability during the bending process. The support plate 9 is arranged on the inlet side of the bending turntable 1, and the support plate 9 is provided with a transversely penetrating support opening 10 on the front side corresponding to the position of the wire opening 8, and a wire limit plug 11 is provided in the support opening 10. When the wire limit plug 11 is inserted into the support opening 10, the steel wire can move along the wire direction, but it prevents the steel wire from escaping from the support opening 10, so that during the bending process of the steel wire, the moving trajectory of the wire between the support plate 9 and the bending turntable 1 can be kept unchanged.

[0030] Specifically, Figure 5 As shown, a pull-out handle 16 is provided at one end of the wire limiting plug 11 and the wire interfering plug 7 away from the steel wire. The pull-out handle 16 facilitates better grasping of the wire limiting plug 11 and the wire interfering plug 7, and is convenient for actual control and use.

[0031] The working principle, use process and technical advantages of the bending device of the present invention are as follows: due to the physical properties of steel itself, manual bending is difficult to operate, so the present invention adopts a drive motor 5 for bending drive, and uses a bending turntable 1 as a bending abutment mold for the steel wire to realize automated steel wire bending. When the steel wire is actually bent, the steel wire is passed through the supporting opening 10 and the wire opening 8 in turn, and then the wire resistance plug 7 is used to insert it into the wire opening 8, one end of the wire is fixed, and the wire limit plug 11 is inserted into the supporting opening 10 to prevent the wire from slipping out of the supporting opening 10, so that the steel wire is supported on the bending turntable 1 and the supporting thick plate 9, and then the rotation angle of the driving motor 5 is set and started. At this time, the wire fixing mechanism can move to a circular arc position in the direction away from the supporting thick plate 9. When in the moving position, the steel wire is driven to bend along the outer ring of the bending turntable 1 to the corresponding outer diameter. At this point, the steel wire can be bent. When it is necessary to take out the steel wire, the wire resistance plug 7 and the wire limit plug 11 are taken out, and the bent steel wire can be removed, which is convenient for subsequent processing. The entire steel wire processing process only requires manual placement of the steel wire, and limiting and fixing it through the wire resistance plug 7 and the wire limit plug 11, and then starting the drive motor 5 to achieve the bending effect of the steel wire. The overall bending process is simple and convenient to operate, and the motor is used as the bending power, so the bending effect is better and the efficiency is higher.

[0032] As an embodiment of the present utility model, Figure 1 As shown, at least two groups of bending turntables 1 are provided, and the centers of the multiple bending turntables 1 are all set on the rotor end axis of the drive motor 5. The bending turntable 1 with the largest diameter is closest to the drive motor 5. The bending turntables 1 are arranged in sequence from large to small in diameter along the direction away from the drive motor 5. Adjacent bending turntables 1 are fixedly connected, and multiple groups of bending turntables 1 are arranged in sequence, so that one drive motor 5 can be used to drive multiple bending turntables 1, that is, to achieve bending of steel wires at different angles, which can meet more needs.

[0033] As an embodiment of the present utility model, Figure 6 and 7As shown, the bending mounting base is provided with a sunken groove 12 at the bottom corresponding to the innermost part of the wire opening 8. The sunken groove 12 is used to accommodate the steel wire to be bent. When the wire contact plug 7 is arranged inside the wire opening 8, the bottom surface of the end of the wire contact plug 7 is in contact connection with the top surface of the steel wire arranged in the sunken groove 12. At the position corresponding to the sunken groove 12 on the bending mounting base, a threaded pin hole 13 is further provided. A fixing pin 14 is arranged in the threaded pin hole 13. When the steel wire needs to be fixed, the fixing pin 14 is screwed into the threaded pin hole 13 and abuts against and fixes the steel wire. The position of the steel wire can be better determined through the sunken groove 12, and the steel wire can be fixed more stably through the fixing pin 14, reducing the possibility of the wire falling off during the bending process.

[0034] Further, as Figure 3 shown, the supporting thick plate 9 is provided with a limiting groove 15 at the bottom corresponding to the innermost part of the supporting opening 10. The limiting groove 15 is used to accommodate the steel wire to be bent, which is convenient for better limiting the steel wire at the position of the supporting thick plate 9 and greatly avoids the position deviation of the steel wire at the position of the supporting thick plate 9 during the bending process of the steel wire.

[0035] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention; any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
