Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, specifically to an adjustable, non-disassembly-required bending machine. Background Technology

[0002] A bending machine is an essential piece of equipment for processing sheet metal. By precisely controlling pressure and angle, it can bend metal materials into various shapes and is widely used in many fields such as machinery manufacturing, automotive industry, and construction decoration. Bending machines are easy to operate, and parameters can be adjusted according to different processing needs. They are highly efficient and precise, effectively improving the quality and efficiency of sheet metal processing, making them an indispensable tool in modern manufacturing.

[0003] Chinese patent CN214639836U discloses a rebar bending machine, relating to the field of construction engineering technology. It aims to solve the problem of reducing mechanical wear in rebar bending machines. The key technical points are: a machine body, a bending device mounted on the machine body, and a feeding device mounted on the machine body. The top surface of the machine body has a bending groove and sliding grooves on both sides of the bending groove. The bending device includes a bending block slidably connected within the bending groove. A drive device connected to the bending block is mounted on the machine body. Bending point one and bending point two are located on the side of the feeding table closest to the bending block. The distance between the sliding grooves and the bending grooves gradually increases from the distance away from bending point two. A distance-fixing device is provided between the bending block and the stop block, keeping the distance between bending point one and bending point two constant. This bending machine is suitable for bending parts at different angles, reducing wear, increasing the processing accuracy of rebar bending, thereby reducing rebar waste and achieving an environmentally friendly effect.

[0004] The bending machine described in the aforementioned patent document first places the workpiece on the feeding table during operation. Then, a driving mechanism moves the bending block, applying external force to it, causing the workpiece to bend. However, the feeding table of this bending machine is rotatably mounted on a stop block. When the workpiece bends under external force, the feeding table rotates along the axis of the stop block. After the workpiece completes the bending process, the operator needs to manually readjust the feeding table to its initial working state before processing the next workpiece. This makes the bending machine extremely inconvenient to use and reduces production efficiency. Therefore, an adjustable, non-disassembly-required bending machine is proposed. Utility Model Content

[0005] To address the aforementioned issues, an adjustable, non-disassembly-required bending machine is provided. When the rotating seat is subjected to external force, it rotates axially along the first mounting shaft. At this time, the tension spring undergoes elastic deformation, storing elastic potential energy. When the workpiece bending process is completed and the external force acting on the rotating seat disappears, the tension spring releases the stored elastic potential energy and generates a restoring force. Under the action of the restoring force, the rotating seat can automatically return to its initial position, thus achieving automatic reset of the rotating seat.

[0006] To address the problems of existing technologies, this application provides an adjustable, non-disassembly-removable bending machine, including a worktable. Two sets of clamping mechanisms capable of moving closer to or further away from each other are provided on the worktable. Each clamping mechanism includes a slide block, with a first mounting shaft vertically positioned at the center of the top of the slide block. A rotatable rotating seat is mounted on the first mounting shaft. A set of rotatable first limiting rollers is mounted on the top of the rotating seat. An adjustment mechanism capable of horizontal adjustment and cooperating with the first limiting rollers to clamp the workpiece is also provided on the top of the rotating seat. Two sets of tension springs symmetrically arranged on the slide block for resetting the rotating seat are mounted on the rotating seat at the end furthest from the slide block.

[0007] As one technical solution of this application, a first column for mounting a tension spring is provided on the slide near the side of the rotating seat; a second column is provided on the top of the rotating seat, and the two ends of the tension spring are respectively hinged to the first column and the second column.

The first limiting roller is sleeved on the second mounting shaft, and a fastener is provided on the top of the second mounting shaft. The fastener is used to mount the first limiting roller on the second mounting shaft.

[0009] As one technical solution of this application, the rotating seat is provided with a threaded hole for installing the adjustment mechanism; the rotating seat is also provided with a limiting groove that enables the adjustment mechanism to move in a specific direction.

[0010] As one technical solution of this application, the adjustment mechanism includes a threaded rod horizontally installed inside the threaded hole, one end of the threaded rod is movably provided with a movable frame that can slide along the limiting groove, and a second limiting roller that can move closer to or further away from the first limiting roller is vertically provided on the movable frame.

[0011] As one technical solution of this application, the worktable is provided with two symmetrically arranged first slide grooves along the X-axis direction. The first slide grooves are horizontally provided with first lead screws for driving the two sets of slide blocks to move closer or further apart. The slide blocks are movably mounted on the first lead screws. A first servo motor for driving the first lead screws to rotate is fixed on one side of the worktable. One end of the first lead screw is fixedly connected to the output end of the first servo motor.

[0012] As one technical solution of this application, a second slide groove is provided on the worktable along the Y-axis direction, and a second lead screw is rotatably arranged inside the second slide groove; a bending die is slidably arranged inside the second slide groove, and a first slider mounted on the second lead screw is provided at the bottom of the bending die; a handwheel for driving the second lead screw to rotate is provided on the front of the worktable, and the handwheel is arranged on the extension end of the second lead screw.

[0013] As one technical solution of this application, the top of the worktable is provided with a bending roller that can move along the Y-axis direction; the top of the worktable is provided with a first hydraulic telescopic component for driving the bending roller closer to or away from the bending die, the bending roller is provided on the output end of the first hydraulic telescopic component, and the bending roller cooperates with the bending die to bend the workpiece.

The cutting mechanism includes a base disposed inside the workbench, and a blade groove is provided on the top of the base. The cutting mechanism also includes a second hydraulic telescopic component disposed on the top of the workbench and close to the base.

[0015] The advantages of this utility model compared to the prior art are:

[0016] When the rotating seat is subjected to an external force, it rotates axially along the first mounting shaft. At this time, the tension spring undergoes elastic deformation, storing elastic potential energy. When the workpiece bending process is completed and the external force acting on the rotating seat disappears, the tension spring releases the stored elastic potential energy and generates a restoring force. Under the action of the restoring force, the rotating seat can automatically return to its initial position, thus achieving automatic reset of the rotating seat. Attached Figure Description

[0025] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0026] See Figures 1-6 As shown, an adjustable, non-disassembly type bending machine includes a worktable 1. Two sets of clamping mechanisms 5 are provided on the worktable 1, which can move closer to or further away from each other. Each clamping mechanism 5 includes a slide 51, with a first mounting shaft 513 vertically positioned at the center of the top of the slide 51. A rotatable rotating seat 52 is mounted on the first mounting shaft 513. A set of rotatable first limiting rollers 523 are mounted on the top of the rotating seat 52. An adjustment mechanism 55, which can be horizontally adjusted and cooperates with the first limiting rollers 523 to clamp the workpiece, is also provided on the top of the rotating seat 52. Two sets of tension springs 53 are symmetrically arranged on the slide 51 for resetting the rotating seat 52. The end of the tension spring 53 furthest from the slide 51 is mounted on the rotating seat 52.

[0027] The system comprises two sets of clamping mechanisms 5 mounted on the worktable 1. The core component of each clamping mechanism 5 is a slide 51, with a first mounting shaft 513 vertically mounted at the top center of the slide 51. A rotating seat 52 rotates along the center of the first mounting shaft 513. The rotating seat 52 can freely rotate around the central axis of the first mounting shaft 513 to accommodate workpieces of different shapes and sizes. A set of rotatable first limiting rollers 523 is mounted on the top of the rotating seat 52. These rollers initially contact and guide the workpiece into the clamping area. Furthermore, the rotating seat 52 is equipped with an adjusting mechanism 55, which can be horizontally adjusted to allow the adjusting mechanism 55 and the first limiting rollers 523 to clamp the workpiece. Two sets of tension springs 53 are symmetrically mounted on the slide 51. One end of each tension spring 53 is mounted on the slide 51, and the other end is mounted on the rotating seat 52, providing a restoring torque for the rotating seat. When the rotating seat 52 rotates, the tension spring 53 stores elastic potential energy; when the external force decreases or disappears, the tension spring 53 releases the elastic potential energy, causing the rotating seat 52 to return to its initial state, and the tension spring 53 causes the rotating seat 52 to return to its initial state, ready for the next clamping operation.

[0028] See Figure 3 As shown, a first column 512 for mounting a tension spring 53 is provided on the slide 51 near the side of the rotating seat 52; a second column 521 is provided on the top of the rotating seat 52, and the two ends of the tension spring 53 are respectively hinged to the first column 512 and the second column 521.

[0029] When the rotating seat 52 rotates, the position of the second column 521 relative to the first column 512 changes. At this time, the tension spring 53 undergoes elastic deformation, storing elastic potential energy. When the external force causing the workpiece to bend disappears or decreases to a certain extent, the tension spring 53 releases the stored elastic potential energy, generating a restoring force that returns the rotating seat 52 to its initial position. This achieves automatic reset of the rotating seat 52.

[0030] See Figure 3 As shown, a second mounting shaft 522 for mounting the first limiting roller 523 is vertically arranged near the center of the top of the rotating seat 52. The first limiting roller 523 is sleeved on the second mounting shaft 522. A fastener 524 is provided on the top of the second mounting shaft 522. The fastener 524 is used to mount the first limiting roller 523 on the second mounting shaft 522.

[0031] First, the first limiting roller 523 is axially fixed using fasteners 524 to prevent it from moving axially along the second mounting shaft 522 during operation. After the first limiting roller 523 is mounted on the second mounting shaft 522, it can rotate axially around the second mounting shaft 522, preventing friction between the workpiece and the surface of the first limiting roller 523 when the workpiece is bent.

[0032] See Figure 3 As shown, the rotating base 52 is provided with a threaded hole 526 for mounting the adjustment mechanism 55; the rotating base 52 is also provided with a limiting groove 525 that enables the adjustment mechanism 55 to move in a specific direction.

[0033] The adjusting mechanism 55 is connected to the threaded hole 526 on the rotating seat 52 via its threaded portion. This allows the adjusting mechanism 55 to move axially along the center axis of the threaded hole 526. Simultaneously, the bottom of the adjusting mechanism 55 is embedded in the limiting groove 525 on the rotating seat 52. When adjusting the adjusting mechanism 55, it can slide along the inside of the limiting groove 525, thereby enabling the adjusting mechanism 55 to move in a specific direction and ensuring that the adjusting mechanism 55 moves according to a predetermined path and range.

[0034] See Figure 3 As shown, the adjustment mechanism 55 includes a threaded rod 551 horizontally installed inside the threaded hole 526. One end of the threaded rod 551 is movably provided with a movable frame 552 that can slide along the limiting groove 525. A second limiting roller 553 that can move closer to or further away from the first limiting roller 523 is vertically provided on the movable frame 552.

[0035] When the second limiting roller 553 is adjusted to approach the first limiting roller 523, the threaded rod 551 is rotated, causing it to move axially within the threaded hole 526. At this time, the threaded rod 551 drives the movable frame 552 and the second limiting roller 553 to move together. The movable frame 552 is movably mounted on the threaded rod 551, with its bottom confined within the limiting groove 525 of the rotating seat 52. Therefore, when the threaded rod 551 rotates and moves axially, the movable frame 552 slides along the predetermined path of the limiting groove 525, ensuring the stability of the adjusting mechanism 55 during movement. Simultaneously, the second limiting roller 553 on the movable frame 552 moves closer to or further away from the first limiting roller 523, allowing the second limiting roller 553 and the first limiting roller 523 to cooperate in clamping the workpiece, preventing it from falling off during bending.

[0036] See Figure 2 , Figure 3 and Figure 7 As shown, the worktable 1 has two symmetrically arranged first slide grooves 15 along the X-axis. The first slide groove 15 has a first lead screw 12 horizontally arranged inside it to drive the two sets of slide blocks 51 to move closer or further apart. The slide blocks 51 are movably mounted on the first lead screw 12. A first servo motor 11 is fixed on one side of the worktable 1 to drive the first lead screw 12 to rotate. One end of the first lead screw 12 is fixedly connected to the output end of the first servo motor 11.

[0037] The slide block 51 is stationary on the first lead screw 12 and is in an initial position within the first slide groove 15. The first lead screw 12 is also stationary at this time, the first servo motor 11 is not started, and the entire system is in standby mode.

[0038] When the slide block 51 needs to move, the first servo motor 11 is activated. The first servo motor 11 begins to rotate according to the control command, and its output directly transmits the rotational power to the first lead screw 12, which is fixedly connected to it, causing the lead screw 12 to rotate around its own axis. Since the slide block 51 is movably mounted on the first lead screw 12, if the first lead screw 12 rotates clockwise, it causes the two sets of slide blocks 51 to move closer together; conversely, if the first lead screw 12 rotates counterclockwise, it causes the two sets of slide blocks 51 to move further apart. Simultaneously, the two sets of slide blocks 51 move linearly along the X-axis direction defined by the first slide groove 15, preventing the slide blocks 51 from deviating from their predetermined trajectory.

[0039] See Figure 4 and Figure 7 As shown, a second slide groove 16 is provided on the worktable 1 along the Y-axis direction, and a second lead screw 13 is rotatably arranged inside the second slide groove 16; a bending die 3 is slidably arranged inside the second slide groove 16, and a first slider 31 is provided at the bottom of the bending die 3 and mounted on the second lead screw 13; a handwheel 14 for driving the second lead screw 13 to rotate is provided on the front of the worktable 1, and the handwheel 14 is arranged on the extension end of the second lead screw 13.

[0040] The second lead screw 13 is rotatably installed inside the second slide groove 16. The bending die 3 is connected to the second lead screw 13 via the first slider 31 at the bottom, and then the second lead screw 13 is driven to rotate by the handwheel 14. The thread on the second lead screw 13 engages with the thread inside the first slider 31, allowing the first slider 31 to slide inside the second slide groove 16. Ultimately, the linear motion of the first slider 31 in the Y-axis direction directly drives the bending die 3 to slide precisely in a straight line along the Y-axis direction under the guidance constraint of the second slide groove 16. This achieves the position adjustment of the bending die 3 in the Y-axis direction, thereby allowing the bending die 3 to be adjusted according to the bending angle of the workpiece.

[0041] See Figure 7 As shown, the top of the worktable 1 is provided with a bending roller 21 that can move along the Y-axis direction; the top of the worktable 1 is provided with a first hydraulic telescopic component 2 for driving the bending roller 21 closer to or away from the bending die 3. The bending roller 21 is located on the output end of the first hydraulic telescopic component 2. The bending roller 21 cooperates with the bending die 3 to bend the workpiece.

[0042] When bending of the workpiece is required, the first hydraulic telescopic assembly 2 is activated. The output end of the first hydraulic telescopic assembly 2 extends or retracts, thereby driving the bending roller 21 to move closer to or further away from the bending die 3 along the Y-axis. Simultaneously, the bending die 3 is adjusted to a designated position along the second slide groove 16 via the first slider 31. Driven by the first hydraulic telescopic assembly 2, the bending roller 21 moves closer to the bending die 3, and at the same time, the bending roller 21 applies appropriate pressure to the workpiece, so that the bending roller 21 and the bending die 3 work together to bend the workpiece.

[0043] See Figure 5 , Figure 6 and Figure 7 As shown, a cutting mechanism 4 for cutting workpieces is provided on the top of the workbench 1. The cutting mechanism 4 includes a base 41 disposed inside the workbench 1. A blade groove 412 is provided on the top of the base 41. The cutting mechanism 4 also includes a second hydraulic telescopic component 42 disposed on the top of the workbench 1 and close to the base 41. A cutting blade 421 that can cooperate with the blade groove 412 to cut the workpiece is fixed at the output end of the second hydraulic telescopic component 42. A third sliding groove 411 is provided on the side of the blade groove 412 on the top of the base 41. A second slider 422 that can slide along the inside of the third sliding groove 411 is provided at the bottom of the cutting blade 421.

[0044] When the workpiece needs to be cut, the second hydraulic telescopic assembly 42 drives the output end to move the cutting blade 421 horizontally. Simultaneously, the second slider 422 at the bottom of the cutting blade 421 slides smoothly along the third groove 411 until the cutting blade 421 fully enters the blade groove 412 and contacts the workpiece. At this point, the second hydraulic telescopic assembly 42 drives the cutting blade 421, causing it to apply sufficient cutting force to the workpiece, thereby achieving the cutting of the workpiece.

[0045] In operation, this invention first uses two sets of relatively movable clamping mechanisms 5 to stably clamp the workpiece. The core component of each clamping mechanism 5, the slide block 51, is fixed to the first lead screw 12, which is driven to rotate by the first servo motor 11. This rotation causes the slide block 51 to move linearly along the X-axis within the first sliding groove 15, allowing the two clamping mechanisms 5 to move closer or further apart to accommodate workpieces of different sizes. The rotating seat 52 on the slide block 51 can rotate freely around the first mounting shaft 513. The first limiting roller 523 on the first mounting shaft 513 is used to initially contact and guide the workpiece into the clamping area. By adjusting the axial movement of the threaded rod 551 in the threaded hole 526 on the adjusting mechanism 55, the movable frame 552 and the second limiting roller 553 slide along a predetermined path in the limiting groove 525. This allows the second limiting roller 553 to cooperate with the first limiting roller 523 to clamp the workpiece, ensuring that the workpiece does not fall off during bending. The tension spring 53 provides a reset torque for the rotating seat 52, ensuring that the clamping mechanism 5 can automatically reset to its initial state after the external force is removed. The bending die 3 is connected to the second lead screw 13 via the first slider 31. The second lead screw 13 is driven to rotate by the handwheel 14, causing the bending die 3 to move linearly along the Y-axis in the second slide groove 16, thereby adjusting the position of the bending die 3 to adapt to the bending angle requirements of different workpieces. When the workpiece needs to be bent, the first hydraulic telescopic component 2 drives the bending roller 21 to move closer to or further away from the bending die 3 along the Y-axis until the bending roller 21 and the bending die 3 work together to apply appropriate pressure to the workpiece, completing the bending process. During the cutting process, the second hydraulic telescopic component 42 drives the cutting blade 421 to move horizontally. The second slider 422 at the bottom of the cutting blade 421 slides smoothly along the third slide groove 411 until the cutting blade 421 fully enters the blade groove 412 and contacts the workpiece. At this time, the second hydraulic telescopic component 42 applies sufficient cutting force to cut the workpiece.
