Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, and more specifically, to an encoder device for a bending machine. Background Technology

[0002] Roll bending machines are commonly used bending equipment for aluminum alloys and various metal profiles. They can process shapes such as circles, arcs, ellipses, and parabolas. To better understand the working efficiency of the roll bending machine and accurately control the dimensions of the workpiece, it is often necessary to measure the workpiece's displacement. Current technology generally uses encoders to measure this displacement.

[0003] For example, Chinese utility model with publication number CN206925162U discloses an encoder mounting bracket, which has a roller set on the upper end of the encoder. When in use, the drive device drives the encoder and the roller to rise, so that the roller presses against the lower surface of the workpiece. The roller and the encoder are connected by belt drive. The encoder indirectly measures the displacement of the workpiece by receiving the number of rotations of the roller. After processing, the encoder is lowered to remove the workpiece.

[0004] However, when measuring the displacement of a workpiece using the above method, the encoder and roller can only move up and down along the Z-axis. When the workpiece to be bent is a wide plate, the encoder and roller cannot move back and forth along the Y-axis, which means they cannot precisely press against the center of the bottom of the plate. When the bending machine is working, the plate is easily subjected to uneven force under the pressure of the upper pressure roller, resulting in bending deformation. When the workpiece to be bent is a narrow metal tube, the position of the metal tube must be precisely aligned with the roller before bending to ensure that the roller presses firmly against the metal tube, which is cumbersome.

[0008] In the encoder device of the above-mentioned bending machine, a roller is provided on the upper end of the encoder, the encoder and the roller are located on the same side of the bracket, and a synchronous pulley is provided on the other side of the bracket, which is connected to the encoder and the roller respectively. The two synchronous pulleys are connected by synchronous belt drive.

[0009] In the encoder device of the above-mentioned bending machine, the second moving component includes a cylinder fixedly connected to the lower end of the support base plate. The output end of the cylinder passes through the support base plate and is fixedly connected to the lower end of the connecting plate. The lower end of the connecting plate is provided with a guide rail, and a slider is slidably connected to the guide rail. The slider is fixedly connected to the lower end of the support base plate.

[0010] In the encoder device of the above-mentioned bending machine, the guide rail part includes a guide rail plate and a second guide rail. The guide rail plate is fixedly connected to the lower end of the connecting plate, and the second guide rail is located between the guide rail plate and the slider part. The second guide rail is fixedly connected to the guide rail plate.

[0011] In the encoder device of the aforementioned bending machine, the slider part includes a second sliding plate fixedly connected to the lower end of the support base plate, a second slider is provided between the second sliding plate and the guide rail part, the second sliding plate and the second slider are fixedly connected, and the second slider is slidably connected to the guide rail part.

[0012] In the encoder device of the aforementioned bending machine, the guide rail and the slider are two pairs and are symmetrically arranged with the cylinder as the center.

[0013] In the encoder device of the aforementioned bending machine, side fixing plates are provided on both sides of the first slide plate.

[0014] The beneficial effects of this utility model are: under the action of the first moving component and the second moving component, the encoder can reciprocate along the Z-axis and Y-axis when in use.

Detailed Implementation

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0018] Figure 4 The diagram illustrates the operational status of the encoder device, located below the work rollers of the roll bending machine. The encoder device's back plate 1 is fixedly connected to the roll bending machine. During operation, the workpiece is placed between the upper pressure roller 9 and the lower pressure roller 10. The upper pressure roller 9 is driven to press the workpiece downwards, while the encoder device pushes the workpiece upwards. The position of the roller 7 is adjusted according to the workpiece size and position. The rotation of the work rollers moves the workpiece, and the workpiece simultaneously drives the roller 7 to rotate synchronously. A belt drive connects the encoder 5 and the roller 7. The encoder 5 measures the angular displacement of the roller 7 and sends the measured data as an electrical signal to a connected CNC, PLC, or control system to calculate the workpiece's displacement. When the roll bending process is complete, the upper pressure roller 9 moves upwards, the encoder device moves downwards, and the processed workpiece is removed.

[0019] Combination Figures 1 to 3An encoder device for a roll bending machine includes a back plate 1 fixedly connected to the roll bending machine. A support base plate 2 is provided on one side of the back plate 1. A connecting plate 3 is provided on the upper end of the support base plate 2. A first moving component 4 is provided on the upper end of the connecting plate 3. An encoder 5 is provided on the first moving component 4. The encoder 5 can reciprocate along the Y-axis under the action of the first moving component 4. A second moving component 6 is provided on the lower end of the connecting plate 3. The encoder 5 can reciprocate along the Z-axis and Y-axis under the action of the first moving component 4 and the second moving component 6. The Z-axis movement facilitates loading and unloading and measuring workpiece displacement. At the same time, the position of the encoder 5 in the Y-axis direction can be adjusted according to the size and position of the workpiece, so that the encoder 5 can accurately measure the workpiece displacement and improve work efficiency.

[0020] Specifically, the first moving component 4 in this embodiment includes a first guide rail 41 fixedly connected to the upper end of the connecting plate 3, a first slider 42 slidably connected to the first guide rail 41, a first slide plate 43 fixedly connected to the upper end of the first slider 42, a bracket 44 fixedly connected to one end of the first slide plate 43, and an encoder 5 located on the bracket 44. The first moving component 4 can be connected to a driving device such as a cylinder, or it can be moved manually. During operation, the bracket 44 is driven, the bracket 44 drives the first slide plate 43 to move, and the first slide plate 43 drives the first slider 42 to move linearly along the first guide rail 41, thereby causing the encoder 5 installed on the bracket 44 to move in the Y-axis direction. The structure is compact, easy to install, and can achieve rapid movement.

[0021] In this embodiment, the encoder 5 is provided with a roller 7 at its upper end. The encoder 5 and the roller 7 are located on the same side of the bracket 44. The other side of the bracket 44 is provided with a synchronous pulley 8 that is connected to the encoder 5 and the roller 7 respectively. The two synchronous pulleys 8 are connected by a synchronous belt drive. The encoder 5 measures the displacement of the workpiece by measuring the displacement of the roller 7 that is close to the workpiece. This can avoid the encoder 5 directly contacting the workpiece, reduce the wear of the encoder 5, and ensure the measurement accuracy of the encoder 5. At the same time, the roller 7 can be made of a material with good rigidity to avoid wear of the roller.

[0022] Specifically, the second moving component 6 in this embodiment includes a cylinder 61 fixedly connected to the lower end of the supporting base plate 2. The output end of the cylinder 61 passes through the supporting base plate 2 and is fixedly connected to the lower end of the connecting plate 3. The lower end of the connecting plate 3 is provided with a guide rail 62, and a slider 63 is slidably connected to the guide rail 62. The slider 63 is fixedly connected to the lower end of the supporting base plate 2. In use, the cylinder 61 is driven to push the connecting plate 3 upward with its output end, thereby driving the encoder 5 on the connecting plate 3 to move upward. At the same time, the guide rail 62 and the slider 63 at the lower end of the connecting plate 3 cooperate with each other to prevent the connecting plate 3 from deviating or shifting during the up-and-down movement.

[0023] In this embodiment, the guide rail part 62 includes a guide rail plate 621 and a second guide rail 622. The guide rail plate 621 is fixedly connected to the lower end of the connecting plate 3, and the second guide rail 622 is located between the guide rail plate 621 and the slider part 63. The second guide rail 622 is fixedly connected to the guide rail plate 621. Since the linear guide rail itself is narrow, if one end of the linear guide rail is directly connected to the connecting plate 3, the pressure on the linear guide rail itself will be large due to the small force-bearing area. Long-term use may cause the linear guide rail to be slightly bent. However, by connecting the guide rail plate 621 to the connecting plate 3 and then connecting the guide rail plate 621 to the side of the second guide rail 622, the force-bearing area can be increased and the pressure on the second guide rail 622 can be reduced.

[0024] Preferably, the slider part 63 in this embodiment includes a second sliding plate 631 fixedly connected to the lower end of the support base plate 2. The second sliding plate 631 and the guide rail part 62 are provided with a second slider 632. The second sliding plate 631 and the second slider 632 are fixedly connected, and the second slider 632 is slidably connected to the guide rail part 62. The second sliding plate 631 can provide better support for the support base plate 2. At the same time, the second slider 632 is connected to the second sliding plate 631 instead of being directly connected to the support base plate 2, which makes the stability of the whole device better.

[0025] It is worth noting that the guide rail section 62 and the slider section 63 are two pairs and are symmetrically arranged with the cylinder 61 as the center; the arrangement of two pairs of guide rail assemblies makes the encoder 5 more stable when moving up and down on the Y-axis and less prone to displacement.

[0026] In this embodiment, side fixing plates 45 are provided on both sides of the first sliding plate 43. When the bending machine stops working, the encoder 5 moves down, and the connecting plate 3 is pressed against the support base plate 2. The weight above the first guide rail 41 is entirely on the first guide rail 41, which can easily lead to damage to the guide rail over time. By providing the side fixing plates 45, when the connecting plate 3 is pressed against the support base plate 2, the side fixing plates 45 are also pressed against the support base plate 2, which can distribute some of the pressure above the first guide rail 41 to the support base plate 2, reducing the pressure on the first guide rail 41.

[0027] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
