Description

Technical Field

[0001] This utility model belongs to the technical field of metal wire processing equipment, specifically an integrated iron wire bending and welding machine. Background Technology

[0002] Iron wire is a linear product made by drawing iron. According to its use, it can be divided into:

[0003] Construction wire: It has a wide range of applications in the construction field, such as for tying steel bars to ensure the stability of the steel bar cage and to keep the steel bars in the correct position during concrete pouring.

[0004] Craft wire: Commonly used to make various handicrafts, such as wire flowers and wire animal shapes. This type of wire is usually thin, flexible, and easy to bend and shape.

[0005] Agricultural wire: It can be used to build the frame and fence of vegetable greenhouses. It needs to have a certain strength and corrosion resistance to adapt to harsh outdoor environmental conditions.

[0006] During wire processing, the wire may be bent or welded. Traditional production methods generally adopt a work mode that separates bending and welding processes. Specifically, operators first process the wire into specific shapes (such as U-shaped hooks, rectangular frames, etc.) on a bending machine, and then manually transport it to the welding station for joining. This results in low efficiency and large positioning errors due to handling. Utility Model Content

[0007] To solve the above-mentioned technical problems, this utility model provides an integrated wire bending and welding machine to solve the problems of low efficiency and large positioning errors caused by the separate steps of bending and welding of wire in the prior art.

[0008] An integrated wire bending and welding machine includes a main unit housing, a secondary unit housing on one side of the main unit housing, and rotating shafts symmetrically arranged in front of the main unit housing and the secondary unit housing. Bending and twisting knives are arranged on the outer wall of the rotating shaft near the bottom. A power assembly connected to the rotating shaft is arranged inside the main unit housing and the secondary unit housing. An upper column head and a lower column head, which are symmetrically arranged and energized between the two bending and twisting knives, are arranged vertically. The upper column head presses down and contacts the lower column head to weld the wire.

[0009] The front end of the main unit is provided with a pad on the side of the upper column away from the sub-unit. Below the pad is a cutting blade for passing through the wire, and on the other side of the cutting blade is a motor.

[0010] Preferably, the power assembly includes a toothed belt, toothed pulleys, a power shaft, and a motor. The toothed belt is symmetrically arranged on the main unit and the auxiliary unit. There are two toothed pulleys on one side of the toothed belt. The rotating shaft is connected to the toothed pulley with a smaller diameter. The power shaft is connected to the toothed pulley with a larger diameter. The motor is externally powered and installed on the bottom plate inside the main unit. The output shaft of the motor is connected to the power shaft via a coupling.

[0011] Preferably, an auxiliary block is provided between the main unit and the auxiliary unit, and a pressure block is provided in front of the auxiliary block. The vertical cross-sectional profile of the pressure block is "L" shaped. The pressure block extends to the interior of the main unit and the auxiliary unit, where a second power shaft is provided. A second motor is installed inside the auxiliary unit, and the output shaft of the second motor is connected to the second power shaft through a coupling.

[0012] Preferably, a guide plate is provided in front of the upper column head, and the guide plate is inclined downward.

[0013] Preferably, the front end face of the main unit is provided with a support wheel at the wire feeding inlet, the support wheel is rotatably connected to the main unit, and the support wheel is distributed in two rows at intervals.

[0014] Preferably, the front end face of the main unit is provided with guide wheels symmetrically spaced vertically between the support wheel and the cutting blade. Two of the guide wheels are provided with linkage shafts extending into the main unit. The main unit is provided with pulleys mounted on the linkage shafts inside the main unit. A transmission belt is provided between the two pulleys. One of the linkage shafts is provided with a motor. The output shaft of the motor is connected to the linkage shaft through a coupling.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This utility model features a main unit and a secondary unit, with rotating shafts symmetrically mounted on both. A power unit drives the rotating shafts to rotate. A bending and twisting blade is mounted on the bottom outer wall of the rotating shaft. When the wire moves to a set position between the pad and the cutting blade, the motor drives the cutting blade to cut the wire. The rotating shaft rotates, causing the bending and twisting blade to contact the wire and bend it during rotation. When the head of the wire bends above the lower column, the upper column is pressed down and energized. The wire is positioned between the upper and lower columns, thus welding the end of the wire to the wire, achieving synchronous bending and welding of the wire. It can also cut the wire, improving the efficiency of bending and welding the wire. Attached Figure Description

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0026] As attached Figure 1 To be continued Figure 5 As shown:

[0027] Example 1: This utility model provides an integrated wire bending and welding machine, including a main unit box 1, a secondary unit box 2 on one side of the main unit box 1, a rotating shaft 3 symmetrically arranged in front of the main unit box 1 and the secondary unit box 2, a bending and twisting knife 4 arranged on the outer wall near the bottom of the rotating shaft 3, a power assembly connected to the rotating shaft 3 is arranged inside the main unit box 1 and the secondary unit box 2, and an upper column head 5 and a lower column head 6 symmetrically arranged and powered between the two bending and twisting knives 4, the upper column head 5 presses down and contacts the lower column head 6 to weld the wire;

[0028] A pad 7 is provided on the front face of the main unit 1 and on the side of the upper column 5 away from the secondary unit 2. A cutting blade 8 for passing through the wire is provided below the pad 7. A motor 26 is provided on the other side of the cutting blade 8.

[0029] It should be noted that, through the set housing 1, a rotating shaft 3 is symmetrically installed on the housing 1. The power component can drive the rotating shaft 3 to rotate. A bending and twisting knife 4 is installed on the bottom outer wall of the rotating shaft 3. When the iron wire moves to the set position between the pad 7 and the cutting knife 8, the motor 426 drives the cutting knife 8 to cut the iron wire first. The rotation of the rotating shaft 3 causes the bending and twisting knife 4 to contact the iron wire and bend it during rotation. When the head of the iron wire bends above the lower column 6, the upper column 5 is pressed down and energized. The iron wire is located between the upper column 5 and the lower column 6, thereby welding the end of the iron wire to the iron wire, realizing the synchronous bending and welding of the iron wire, and also cutting it, improving the efficiency of bending and welding the iron wire.

[0030] To further explain, when the bending and twisting knife 4 rotates to bend the wire and make its end contact with the upper column head 5 and reach the preset pressure, the electrical control box 24 controls the welding power supply to pass a welding current of preset magnitude and time between the upper column head 5 and the bending and twisting knife 4 to complete the welding. The upper column head 5 is designed to be movable. The upper column head 5 is connected to the motor through a shaft. During the wire conveying process, the motor drives the upper column head 5 to move upward through the shaft so that the wire can pass through normally. When the wire is bent, the motor drives the upper column head 5 to move downward through the shaft so that it fits with the lower column head 6 to weld the wire.

[0031] In this embodiment, the power assembly includes a toothed belt 9, a toothed pulley 10, a power shaft 11, and a motor 12. The toothed belt 9 is symmetrically arranged on the main unit housing 1 and the auxiliary unit housing 2. There are two toothed pulleys 10 on one side of the toothed belt 9. The rotating shaft 3 is connected to the toothed pulley 10 with a smaller diameter. The power shaft 11 is connected to the toothed pulley 10 with a larger diameter. The motor 12 is connected to an external power supply and installed on the bottom plate inside the main unit housing 1. The output shaft of the motor 12 is connected to the power shaft 11 through a coupling.

[0032] It should be noted that motor 12 drives power shaft 11 to rotate. Power shaft 11 is connected to large-diameter toothed pulley 10. There is a toothed belt 9 between the two toothed pulleys 10, which drives another small-diameter toothed pulley 10 to rotate, thereby ultimately driving the rotating shaft 3 to rotate. Moreover, the number of rotating shafts 3 is set to two, and each rotating shaft 3 is equipped with a bending and twisting knife 4, so that both ends of a wire can be bent and welded at the same time. After the bending and welding of a wire is completed, the rotating shaft 3 reverses to return the bending and twisting knife 4 to its original position, without interfering with the transmission of the wire.

[0033] In this embodiment, an auxiliary block 13 is provided between the main unit 1 and the auxiliary unit 2. A pressure block 14 is provided in front of the auxiliary block 13. The vertical cross-sectional profile of the pressure block 14 is "L" shaped. The pressure block 14 extends into the space between the main unit 1 and the auxiliary unit 2 and a second power shaft 15 is provided inside. A second motor 16 is installed inside the auxiliary unit 2. The output shaft of the second motor 16 is connected to the second power shaft 15 through a coupling.

[0034] It should be noted that, through the auxiliary block 13, the wire will pass through the auxiliary block 13 during the forward transmission process. When the wire stops after moving a fixed distance, the motor 16 will drive the power shaft 15 to rotate, thereby causing the pressure block 14 to rotate towards the auxiliary block 13. Finally, the pressure block 14 will contact the wire and press it onto the auxiliary block 13. The purpose of setting the pressure block 14 is mainly to fix the wire that is about to be bent and welded after the cutting knife 8 cuts the wire, to prevent the wire from falling off after cutting, and to ensure the stability of the subsequent bending and welding of the wire.

[0035] In this embodiment, a guide plate 17 is provided in front of the upper column head 5, and the guide plate 17 is inclined downward.

[0036] It should be noted that after the wire is bent and welded, the pressure block 14 will rotate back to its original position. At this time, the wire is no longer fixed and will fall onto the guide plate 17. The guide plate 17 can be used to control the path of the wire falling, so that it can slide down along the guide plate 17 and be collected in a concentrated manner.

[0037] In this embodiment, a support wheel 18 is provided on the front end face of the main unit box 1 at the wire feeding inlet. The support wheel 18 is rotatably connected to the main unit box 1 and is distributed in two rows at intervals.

[0038] It should be noted that the support wheels 18 are arranged vertically. When the wire is fed in, it enters between the vertically arranged support wheels 18, so that it can be better fed between the two subsequent guide wheels 19 for precise wire feeding.

[0039] In this embodiment, guide wheels 19 are symmetrically arranged at intervals between the support wheel 18 and the cutting blade 8 on the front end face of the main unit 1. A linkage shaft 20 extending into the main unit 1 is provided on the two guide wheels 19. A pulley 21 mounted on the linkage shaft 20 is provided inside the main unit 1. A transmission belt 22 is provided between the two pulleys 21. A motor 23 is provided on one of the linkage shafts 20. The output shaft of the motor 23 is connected to the linkage shaft 20 through a coupling.

[0040] It should be noted that the motor 23 drives the linkage shaft 20 to rotate, which in turn drives the pulley 21 to rotate. The two pulleys 21 cooperate with the transmission belt 22, which ultimately causes the two guide wheels 19 to rotate. The wire is located between the two guide wheels 19, and the guide wheels 19 ultimately transport the wire between the pad 7 and the cutter 8, thus realizing the automated transportation of the wire.

[0041] In this embodiment, the main unit 1 is provided with an electrical control box 24 for external power supply on its side wall, and the front end of the auxiliary unit 2 and on the other side of the support wheel 18 are provided with a baffle 25 to block the wire.

[0042] It should be noted that the electric control box 24 controls the motor 12, motor 26, motor 3, and shearing cylinder 7, thereby ensuring integrated cutting, bending, and welding of the wire. The baffle 25 ensures that the end of the wire will contact the baffle 25 after it has been transmitted a fixed distance.

[0043] The embodiments of this utility model are given for the purpose of illustration and description. Although embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the utility model. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this utility model.
