Description
Technical Field
[0001] This utility model relates to the field of metal rod bending equipment technology, and in particular to an automated metal rod bending equipment. Background Technology
[0002] A metal rod bending machine is an industrial device used to bend metal rods (such as steel bars, steel pipes, round steel, square steel, etc.) into specific shapes. It is widely used in construction, machinery manufacturing, automobiles, aerospace and other fields.
[0003] Metal rod bending machines are generally divided into mechanical and hydraulic types. Hydraulic metal rod bending machines, due to their complex structure and high energy consumption, are mostly suitable for bending high-strength metal rods. In machining processes, the bending strength of metal rods is generally not very high, and they often need to be bent multiple times to achieve the desired shape. To facilitate processing and reduce energy consumption and equipment costs, mechanical metal rod bending machines are more commonly used. Currently, mechanical bending machines on the market often use a crank connection structure to manually bend the metal rod, which is time-consuming and labor-intensive, and the bending precision is not high, making it difficult to control the bending angle each time, requiring a high level of skill from the technicians. Furthermore, during the bending process, the template usually needs to be changed according to different bending requirements. Changing the template on the aforementioned mechanical bending machines is very inconvenient. Therefore, it is generally necessary to set up multiple machines to accommodate different bending needs. Utility Model Content
[0004] To address the aforementioned problems, this utility model proposes an automated bending device for metal rods.
[0005] The technical solution adopted by this utility model is: an automated bending device for metal rods, comprising:
[0006] frame;
[0007] A drive unit is mounted on the frame and includes a drive motor and a shaft linked to the drive motor.
[0008] The linkage assembly includes a swing arm, a connecting rod, and a rocker arm, wherein one end of the swing arm is fixed to the shaft, and the connecting rod is disposed between the swing arm and the rocker arm;
[0009] A support plate is disposed above the frame;
[0010] The mold kit includes a transfer plate fixed above a support plate, a rotating assembly mounted above the transfer plate, and a fixture plate disposed above the frame. The rotating assembly includes a shaft seat fixed above the transfer plate, a rotating sleeve sleeved outside the shaft seat, and a pressure bearing fixed above the rotating sleeve. One end of the rocker arm is fixed to the rotating sleeve. The fixture plate has a clamping groove for a metal rod to pass through at one end near the rotating assembly.
[0011] The rotating sleeve rotates around the central seat and bends the metal rod through the driving bearing.
[0012] Several alternative methods are provided below, but they are not intended as additional limitations on the overall solution above. They are merely further additions or optimizations. Provided there are no technical or logical contradictions, each alternative method can be combined individually with respect to the overall solution above, or multiple alternative methods can be combined with each other.
[0013] Preferably, the frame includes a working panel, a proximity switch is installed on the working panel, a sensing block is provided on the swing arm, and the proximity switch is located at the initial end of the movement path of the sensing block.
[0014] Preferably, the working panel has an arc-shaped slot, and the proximity switch is installed on the arc-shaped slot.
[0015] Preferably, the drive device further includes a fixing plate and a bearing seat fixed on the working panel, wherein the drive motor is mounted on the fixing plate and the shaft passes through the bearing seat.
[0016] Preferably, the support plate is suspended above the bearing seat and the shaft by a plurality of first support rods.
[0017] Preferably, the support plate is provided with a plurality of T-shaped grooves spaced apart from each other, and a slider is slidably disposed on the T-shaped grooves, and a locking bolt is provided between the slider and the transfer plate.
[0018] Preferably, the swing arm and the rocker arm are both placed horizontally, and the connecting rod is placed vertically.
[0019] Preferably, the fixture plate is mounted above the work panel via a plurality of second support rods.
[0020] Preferably, the fixture plate has a pressing block at one end near the rotating assembly, and the automated bending equipment further includes a clamping device, which includes a mounting plate installed on the working panel or the support plate, and a drive cylinder installed on the mounting plate. The drive cylinder is used to drive the clamping block to move horizontally, and the clamping groove is formed between the clamping block and the pressing block.
[0021] More preferably, a control mechanism is also provided above the frame, the control mechanism being used to control the operation of the drive motor and the drive cylinder.
[0022] Compared with the prior art, this utility model has the following beneficial effects:
[0023] 1. A geared motor is used to drive the swing arm to rotate. Since there is a connecting rod and a swing arm between the swing arm and the rotating sleeve, the rotating sleeve can be driven to rotate around the shaft seat. During this process, the pressure bearing fixed above the rotating sleeve will drive the metal rod fixed above the jig plate and bend it. The drive is labor-saving, and the bending angle and bending speed of the metal rod can be controlled by the control mechanism.
[0024] 2. After a single bend is completed, the orientation of the metal rod needs to be adjusted manually for the next bend. This means that the only manual step involved is the placement of the metal rod, which is more labor-saving.
[0025] 3. Since the mold kit can be disassembled from the mounting plate and frame, it can be completely disassembled and reassembled when the mold kit needs to be replaced, without the need for additional parts assembly. During the disassembly and assembly of the mold kit, the drive device, mounting plate, swing arm and clamping device do not need to be adjusted, making it easy to operate and highly practical.

[0038] Detailed implementation plan: See below Figures 1-6 This utility model is an automated bending device for metal rods, comprising:
[0039] Rack 1;
[0040] The drive unit 2 is mounted on the frame 1 and includes a drive motor 22 and a shaft 24 linked to the drive motor 22.
[0041] The linkage component 3 includes a swing arm 31, a connecting rod 32 and a rocker arm 33, wherein one end of the swing arm 31 is fixed on the shaft 24, and the connecting rod 32 is disposed between the swing arm 31 and the rocker arm 33;
[0042] Support plate 4 is installed above frame 1;
[0043] The mold kit includes a transfer plate 8 fixed above the support plate 4, a rotating assembly 5 mounted above the transfer plate 8, and a fixture plate 6 set above the frame 1. The rotating assembly 5 includes a shaft seat 51 fixed above the transfer plate 8, a rotating sleeve 52 sleeved outside the shaft seat 51, and a pressure bearing 53 fixed above the rotating sleeve 52. One end of the rocker arm 33 is fixed on the rotating sleeve 52. The fixture plate 6 has a clamping groove for the metal rod a to pass through at one end near the rotating assembly 5.
[0044] The rotating sleeve 52 rotates around the central seat 51 and bends the metal rod a through the pressure bearing 53.
[0045] As a preferred embodiment of this example, please refer to Figure 1 and Figure 3 As can be seen, the frame 1 includes a working panel 11, a proximity switch 10 is installed on the working panel 11, and a sensing block 34 is provided on the swing arm 31. The proximity switch 10 is located at the initial end of the movement path of the sensing block 34.
[0046] In addition, in this embodiment, the working panel 11 is provided with an arc-shaped slot 111, and the proximity switch 10 is installed on the arc-shaped slot 111.
[0047] Here, since the rotation path of the swing arm 31 is arc-shaped, by setting an arc-shaped slot 111 on the work panel 11, the proximity switch 10 can be installed at different positions of the arc-shaped slot 111 as needed to control the initial movement position of the swing arm 31.
[0048] In this embodiment, the swing arm 31 and the rocker arm 33 are both placed horizontally, while the connecting rod 32 is placed vertically.
[0049] Furthermore, for ease of installation, in this embodiment, a connecting block is provided between the connecting rod 32 and the rocker arm 33. The connecting block has a through hole for the rocker arm 33 to pass through. After the rocker arm 33 passes through the through hole, tightening the screws on the connecting block will complete the fixing between the rocker arm 33 and the connecting block.
[0050] The working principle of the drive device 2 and the linkage component 3 working together to drive the rotating sleeve 52 to rotate around the central seat 51 is as follows:
[0051] The drive motor 22 is a geared motor. The drive motor 22 drives the shaft 24 to rotate. Since one end of the swing arm 31 is fixed on the shaft 24, the swing arm 31 can be driven to rotate circumferentially around the shaft 24. Since the connecting rod 32 is fixed between the swing arm 31 and the rocker arm 33, and one end of the rocker arm 33 is fixed on the outer wall of the rotating sleeve 52, the rocker arm 33 will drive the rotating sleeve 52 to rotate around the shaft seat 51 during the circumferential rotation of the swing arm 31 around the shaft 24.
[0052] During the rotation of the rotating sleeve 52 around the central seat 51, the pressure bearing 53 fixed above the rotating sleeve 52 will drive and press the metal rod a fixed above the jig plate 6, causing it to bend. Note that the use of the pressure bearing 53 here ensures that the pressure bearing 53 maintains contact with the metal rod a during the process of driving and pressing the metal rod a.
[0053] Then, please see Figure 1 , Figure 2 , Figure 5 and Figure 6 As can be seen, in this embodiment, the drive device 2 also includes a fixing plate 21 and a bearing seat 23 fixed on the working panel 11, wherein the drive motor 22 is mounted on the fixing plate 21 and the shaft 24 passes through the bearing seat 23.
[0054] In this embodiment, the fixing plate 21 is fixed below the working panel 11, and the bearing seat 23 is fixed above the working panel 11. The setting of the bearing seat 23 allows the shaft 24 to rotate more stably.
[0055] Next, please refer to Figure 1 As can be seen, in this embodiment, the support plate 4 is suspended above the bearing seat 23 and the shaft 24 by a number of first support rods 41.
[0056] In addition, please see Figure 4 As can be seen, in this embodiment, the support plate 4 is provided with a plurality of T-shaped grooves 42 spaced apart from each other, and a slider is slidably arranged on the T-shaped grooves 42. A locking bolt is provided between the slider and the transfer plate 8.
[0057] Here, by setting a T-shaped groove 42 on the support plate 4, when it is necessary to adjust the left and right position of the transfer plate 8, the locking bolt can be loosened. At this time, the slider (with a T-shaped cross-section) can slide left and right in the T-shaped groove 42. After the transfer plate 8 is adjusted to the appropriate position, the locking bolt is tightened again to complete the relative fixation between the transfer plate 8 and the support plate 4.
[0058] Note that the T-slot 42 on the support plate 4, the slider in the T-slot 42, and the mounting structure of the locking bolt between the transfer plate 8 and the slider are existing technologies, and therefore are only briefly described above.
[0059] Please see Figure 1 As can be seen, in this embodiment, the jig plate 6 is mounted above the work panel 11 by a number of second support rods 61.
[0060] When you need to change the template suite, please refer to Figure 4 To remove the template kit, you need to remove the locking bolts between the transfer plate 8 and the support plate 4, remove the screws between the rocker arm 33 and the connecting block, and remove the second support rod 61 between the work panel 11 and the fixture plate 6. The template kit can then be removed entirely. Similarly, the other template kit can be installed back onto the frame 1 and the support plate 4.
[0061] In addition, please see Figure 1 and Figure 4 As can be seen, in this embodiment, the jig plate 6 is provided with a pressing block 62 at one end near the rotating component 5. The automated bending equipment also includes a clamping device 9. The clamping device 9 includes a mounting plate 91 mounted on the working panel 11 or the support plate 4, and a drive cylinder 92 mounted on the mounting plate 91. The drive cylinder 92 is used to drive the clamping block 93 to move back and forth. A clamping groove is formed between the clamping block 93 and the pressing block 62.
[0062] The working principle of clamping device 9: After the metal rod a is placed in the clamping groove, the drive cylinder 92 operates, driving the clamping block 93 to move horizontally towards the side closer to the pressing block 62, thus clamping the metal rod a. When it is necessary to adjust the placement position of the metal rod a, the drive cylinder 92 operates, driving the clamping block 93 to move horizontally away from the pressing block 62, thus removing the metal rod a. After adjusting the placement position of the metal rod a (the metal rod a is placed back in the clamping groove), the drive cylinder 92 operates again, and similarly, the metal rod a is clamped again.
[0063] More specifically, a control mechanism 7 is also provided above the frame 1. The control mechanism 7 is used to control the operation of the drive motor 22 and the drive cylinder 92.
[0064] In this embodiment, the control mechanism 7 is a PLC, which can adjust parameters such as the bending count, bending angle, bending speed, and holding time. When multiple bending angles are set, the metal rod a can be bent sequentially according to the set bending angles during multiple placements.
[0065] The above description of an automated bending device for metal rods is merely a preferred embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
