Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and in particular to a wire bending machine. Background Technology

[0002] In the field of steel wire processing, bending is a common process used to bend steel wire into specific shapes and angles to meet the needs of different products. Traditional steel wire bending machines mostly adopt a cam-type design, which relies on the combination of multiple sets of cams and dies to achieve bending of steel wires into different shapes. Specifically, the cams drive the bending dies to apply pressure to the steel wire through their specific profile curves, causing it to bend and deform. Different bending shapes and angles require cams with corresponding profiles and dies with specific shapes. Therefore, in actual production, in order to meet diverse production needs, multiple sets of cams and dies are often required.

[0003] While this traditional cam-type bending machine can accomplish the task of bending steel wire to a certain extent, it also has many significant drawbacks. Firstly, its complex mechanical structure is one of its most prominent problems. The combination of multiple cams and dies results in a large number of parts in the bending machine, requiring high precision in the assembly of each component. This not only increases the manufacturing cost of the equipment but also raises the difficulty of maintenance. If a component malfunctions, troubleshooting and repair are often cumbersome and require a significant amount of time and manpower.

[0004] Traditional cam-type bending machines are extremely inefficient when producing different types of parts. Because different parts require different bending shapes and angles for the steel wire, each time the production model is changed, the corresponding die must be replaced, and the machine parameters, such as the cam rotation angle and die position, must be manually adjusted. This process is not only cumbersome but also requires operators with high technical skills and extensive experience; otherwise, inaccurate adjustments can easily occur, resulting in steel wire bending parts that do not meet quality requirements. Furthermore, the time-consuming manual parameter adjustment process severely impacts production efficiency and fails to meet the demands of modern industrial production for high efficiency and speed.

[0005] To address the aforementioned problems, this technical solution proposes a wire bending machine. Utility Model Content

[0006] The purpose of this invention is to solve the problems of complex mechanical structure and low changeover efficiency of traditional cam-type bending machines in the prior art, and to propose a wire bending machine.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A wire bending machine includes a work base with a bottom frame fixedly connected to the top of the work base. The bottom frame contains a conveying mechanism, including multiple rotatably connected transmission sprockets at equal intervals and corresponding drive motors. The output shaft of the drive motor is fixedly connected to the transmission sprockets, and the transmission sprockets have an annular groove for limiting the wire. The bottom frame also has a limiting mechanism, including a top frame, an electric push rod I, a movable slide plate, and pressure rollers. The output shaft of the electric push rod I drives the movable slide plate to move longitudinally, causing the pressure rollers to clamp into the annular groove of the transmission sprockets.

[0009] A bending mechanism is provided on one side of the bottom frame, including a support plate, support rollers, bending forming wheel and stepper drive motor. The output shaft of the stepper drive motor is fixedly connected to the rotating ring through a connecting plate. The rotating ring drives the bending forming wheel to make a circular motion to bend the steel wire. The steel wire is conveyed by the conveying mechanism and pressed by the limiting mechanism. It is then passed through the gap between the support roller and the bending forming wheel. The bending is achieved by driving the bending forming wheel to move through the stepper drive motor. The bending angle range can be controlled by adjusting the motor rotation parameters.

[0010] In one possible design, multiple transmission sprockets of the conveying mechanism are rotatably connected to the inner wall of one side of the bottom frame via bearings, and the output shaft of the drive motor is fixedly connected to the end of the transmission sprockets via a coupling.

[0011] In one possible design, the movable slide of the limiting mechanism is slidably connected to the inner wall of the top frame via a slide rail, and the pressure roller is rotatably connected between two support base plates at the bottom of the movable slide via a rotating shaft.

[0012] In one possible design, the support roller of the bending mechanism is installed on the docking ring of the bearing plate by plugging in, and the adjusting and locking plate of the positioning component limits the top of the support roller to be in the docking positioning hole by adjusting the threaded transmission of the threaded rod.

[0013] In one possible design, the rotating ring of the bending mechanism is rotatably connected to the bottom of the bearing plate via a bearing, the fixed plate is fixedly connected to the side wall of the rotating ring, the support frame is fixedly connected to the top of the fixed plate, the movable carriage is slidably connected to the support frame via a guide rail, the bending forming wheel is rotatably connected to the movable carriage via a rotating shaft, and the output shaft of the electric push rod II is fixedly connected to the movable carriage to drive its lateral movement.

[0014] In one possible design, the bending mechanism controls the rotation angle of the rotating ring through the pulse signal of the stepper motor, thereby achieving precise adjustment of the bending angle of the steel wire.

[0015] In one possible design, the conveying mechanism, the limiting mechanism, and the bending mechanism work together to solve the problems of complex structure and low changeover efficiency of traditional bending machines, and to achieve efficient wire conveying and bending at any angle.

[0016] In one possible design, the pressure rollers and transmission sprockets are arranged in a one-to-one correspondence to ensure that the steel wire is subjected to uniform force at all points during transmission and to avoid local deviation.

[0017] In this application, during use, the required support roller is first inserted into the mating connection ring on the bearing plate. Then, the adjusting threaded rod inside the limiting cover is rotated. Under the threaded transmission action of the adjusting threaded rod and the adjusting locking plate, the adjusting locking plate is moved downward, so that the top of the support roller is inserted into the mating positioning hole on the adjusting locking plate, thus completing the limiting support of the support roller. Then, the steel wire is inserted into the annular groove on the transmission sprocket on one side of the bottom frame. The drive motor on one side of the bottom frame is started, which drives the transmission sprocket to rotate. At the same time, multiple electric push rods I on the top frame are started. The electric push rods I drive the moving slide plate to move longitudinally within the top frame. The moving slide plate drives the pressure roller to move downward through the support base plate. With the support and cooperation of the transmission sprocket, the pressure roller presses against the steel wire. The wire is clamped to ensure a tight fit between the wire and the inner wall of the annular groove of the transmission sprocket, achieving stable wire transmission. The wire is then passed through the gap between the support roller and the bending forming wheel on the moving carriage in the bending assembly. The electric push rod II on one side of the support frame is activated, causing the moving carriage to move outwards, clamping the wire with the bending forming wheel. Finally, the stepper drive motor on the top side of the work base is activated. The stepper drive motor drives the rotating ring to rotate via the connecting fixing plate. The rotating ring drives the fixing plate in a circular motion, which in turn causes the bending forming wheel to move in a circular motion, pressing the wire and bending it around the support roller as an axis. The range of motion of the bending forming wheel can be adjusted as needed to bend the wire to any desired angle without frequent changes to the bending die.

[0018] Beneficial effects: In this utility model, the steel wire bending machine can insert the steel wire into the annular groove on the transmission sprocket on one side through the transmission mechanism. Then, the drive motor is started to drive the transmission sprocket to rotate. At this time, under the pressing action of the limiting mechanism, the steel wire can be tightly fitted with the annular groove. Therefore, the rotating transmission sprocket can realize the transmission of the steel wire.

[0019] In this utility model, the steel wire bending machine, through the limiting mechanism, can drive the moving component to move downward by activating multiple electric push rods I. At this time, it can drive multiple pressure rollers to move downward, thereby clamping the steel wire with the support and cooperation of the corresponding transmission sprockets. This allows the steel wire to fit tightly against the inner wall of multiple annular grooves during the conveying process, thus enabling stable conveying of the steel wire.

[0020] In this utility model, a steel wire bending machine can insert the required support roller into the docking connection ring in advance through the bending mechanism, and operate the positioning component to limit and support the support roller. Then, the steel wire is passed through the gap between the support roller and the bending component. At this time, by starting the bending component, the steel wire can be bent around the support roller as the axis by the thrust of the bending component.

[0021] This invention solves the problems of complex mechanical structure and difficult maintenance of traditional cam-type bending machines. It also eliminates the need for frequent mold replacements and manual parameter adjustments during production changes, making it easy to operate and requiring low technical skills from operators. Furthermore, it allows for adjustment of the bending forming wheel's movement range as needed, enabling steel wires to bend at any angle, thus significantly improving production efficiency and meeting the demands of high-efficiency production.

Multiple pressure rollers 8 are distributed at equal intervals between the two support base plates 7. The two ends of the pressure rollers 8 are rotatably connected to the two support base plates 7 respectively. When the multiple electric push rods I9 are activated, the movable slide plate 6 moves longitudinally within the top frame 5, thereby driving the multiple pressure rollers 8 to move downward. With the support and cooperation of the transmission sprocket 3, the steel wire is clamped, so that the steel wire is tightly fitted with the inner wall of the annular groove of the transmission sprocket 3, achieving stable transmission of the steel wire.

[0031] like Figure 4-5As shown, a bending mechanism is installed on one side of the bottom frame 2. The bending mechanism includes a support plate 10 fixedly installed on one side of the bottom frame 2. A docking connection ring 11 is fixedly installed through the support plate 10, and a support roller 16 is inserted into the docking connection ring 11. A positioning component is installed on the top of the support plate 10. The positioning component consists of a limiting cover 12 fixedly installed on the top of the support plate 10. An adjusting locking plate 13 is slidably connected inside the limiting cover 12. One side of the adjusting locking plate 13 extends to the outside of the limiting cover 12. A docking positioning hole 15 is opened on the adjusting locking plate 13 located on the outside of the limiting cover 12. The support roller 16 passes through the docking positioning hole 15 and fits against the inner wall of the docking positioning hole 15. An adjusting threaded rod 14 is rotatably connected to the inner wall of the bottom of the limiting cover 12. The top end of the adjusting threaded rod 14 passes through the adjusting locking plate 13 and the inner wall of the top of the limiting cover 12 and extends above the limiting cover 12. The adjusting threaded rod 14 is threadedly connected to the adjusting locking plate 13. After the support roller 16 is inserted into the docking ring 11, the adjusting threaded rod 14 is rotated. Under the action of thread transmission, the adjusting locking plate 13 is moved downward, so that the top of the support roller 16 is inserted into the docking positioning hole 15, and the support roller 16 is rotated and supported and limited.

[0032] This application can be used in the field of metal processing technology, or in other fields applicable to this application.

[0033] In another embodiment: Reference Figure 5Based on the above embodiments, an improvement is made: a wire bending machine, which is applied to the field of metal processing technology. A drive assembly is rotatably connected to the bottom of a support plate 10. The drive assembly includes a rotating ring 17 rotatably connected to the bottom of the support plate 10.

A support frame 19 located on one side of the support plate 10 is fixedly installed on the top of the fixed plate 18. A movable slide 20 is slidably connected inside the support frame 19. One side of the movable slide 20 extends above the support plate 10. A bending forming wheel 21 is rotatably connected inside the movable slide 20. The bending forming wheel 21 cooperates with a support roller 16. An electric push rod II 22 is fixedly installed on one side of the support frame 19. The output shaft of the electric push rod II 22 extends into the support frame 19 and is fixedly connected to one side of the movable slide 20. After the steel wire passes between the support roller 16 and the bending forming wheel 21, the electric push rod II 22 is activated, driving the movable slide 20 to move outwards from the support frame 19. The bending forming wheel 21 clamps the steel wire, and then the stepper drive motor 24 is activated, driving the connecting fixing plate 23 to rotate, which in turn drives the rotating ring 17 to rotate, causing the fixing plate 18 to move in a circular motion, which in turn drives the bending forming wheel 21 to move in a circular motion, pressing the steel wire and achieving the bending process. By adjusting the rotation parameters of the stepper drive motor 24, the range of motion of the bending forming wheel 21 can be adjusted, thereby bending the steel wire to any required angle without the need for frequent changes of bending dies, providing excellent ease of use.
