Description

Technical Field

[0001] This utility model relates to the field of bending tool technology, and in particular to a bending device for mechanical design and manufacturing. Background Technology

[0002] Mechanical design and manufacturing is a comprehensive discipline that involves transforming raw materials into various mechanical products. It encompasses a series of complex processes, from product conception, design, and analysis to manufacturing process planning and final product molding. In the production of many mechanical products, it is often necessary to bend various metal or non-metal materials to meet the specific shape and structural requirements of the products. Bending devices, as indispensable equipment in the field of mechanical manufacturing, can bend materials such as plates and pipes according to predetermined angles and shapes. They are widely used in many industries such as automobile manufacturing, aerospace, electronic equipment production, and building decoration, and play a crucial role in improving product quality, realizing product function diversification, and increasing production efficiency.

[0003] Traditional bending devices typically employ a fixed mold structure, which mainly consists of two fixed molds, an upper mold mounted on a stamping mechanism and a lower mold fixed on a worktable. During the bending operation, the material to be bent is placed on the lower mold, and the stamping mechanism drives the upper mold to move downwards, causing the material to form a predetermined bending angle or shape under the squeezing action of the upper and lower molds.

[0004] However, this traditional mold-type bending device has significant drawbacks. Its bending angle and shape are basically fixed after the mold is designed and manufactured. When production needs change, it is impossible to bend the material at different angles. The entire mold must be replaced, which will reduce production efficiency. Therefore, a bending device for mechanical design and manufacturing is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a bending device for mechanical design and manufacturing, which aims to improve the problem that in the prior art, the bending angle and shape are basically fixed after the mold design and manufacturing are completed, and it is impossible to bend the material at different angles when production needs change.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A bending device for mechanical design and manufacturing includes a worktable, a bracket fixedly connected to the top of the worktable, a mounting frame fixedly connected to the top of the worktable, a rotating plate rotatably connected to the top of the worktable, a rotating plate rotatably connected to the top of the mounting frame, a bending mechanism on the top of the rotating plate rotatably connected to the rotating plate rotatably, a connecting rod rotatably connected between the rotating plate rotatably and the rotating plate rotatably, and a quick-release mechanism inside the connecting rod; the bending mechanism includes a gear, the gear fixedly connected to the outside of one side of the connecting rod, a pressing roller rotatably connected to the outside of one side of the connecting rod, a guide frame fixedly connected to the top of the worktable, a rack slidably connected inside the guide frame rotatably, a hydraulic rod fixedly connected to the top of the bracket, a pressing roller rotatably connected to the outside of the connecting rod, and a handle fixedly connected to one side wall of the rotating plate;

[0008] As a further description of the above technical solution:

[0009] The quick-release mechanism includes a cylinder, which is fixedly connected inside the connecting rod. A spring is installed inside the cylinder, and a slider is slidably connected inside the cylinder. A locking block is fixedly connected to the side wall of the slider, and a limit rod is rotatably connected inside the second extrusion roller.

[0010] As a further description of the above technical solution:

[0011] The limiting rod is slidably connected to the outside of the connecting rod;

[0012] As a further description of the above technical solution:

[0013] The limiting rod has a groove inside, which engages with the locking block;

[0014] As a further description of the above technical solution:

[0015] One end of the spring is fixedly connected to the inside of the cylinder, and the other end of the spring is fixedly connected to the side wall of the slider;

[0016] As a further description of the above technical solution:

[0017] One of the connecting rods passes through the mounting frame and extends to the outside, and the top of the rotating plate is rotatably connected to the bottom of the mounting frame;

[0021] A guide frame two is fixedly connected to the top of the workbench, and a placement plate is fixedly connected to the side wall of the guide frame two.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by gripping the handle and rotating it, the first rotating plate is driven to rotate. Through the connection of the connecting rod, the second rotating plate also rotates synchronously. The first and second rotating plates rotate around the connecting rod on one side, thereby driving the second extrusion roller to move and extrude and bend the material between the second and first extrusion rollers. This solves the problem that existing bending devices usually bend according to the angle or shape of the mold, and it is inconvenient to adjust the bending angle. Through the above structure, the versatility and production efficiency of the equipment are improved.

[0024] 2. In this utility model, by grasping the second extrusion roller and lifting it upwards, the limiting rod is driven to extrude the locking block, thereby causing the slider to slide inside the cylinder. At this time, the spring is deformed by the force. When the locking block disengages from the groove, the second extrusion roller can be taken out for replacement. This solves the problem that when it is necessary to change molds of different sizes, a lot of time is spent on mold disassembly, installation and debugging, which affects production efficiency. Through the above structure, the speed of mold changing can be improved, thereby promoting production efficiency. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-2 This utility model provides an embodiment of a bending device for mechanical design and manufacturing, comprising a workbench 1, which provides a stable mounting platform for other components. A bracket 2 is fixedly connected to the top of the workbench 1, which supports and fixes other related components. A mounting frame 3 is fixedly connected to the top of the workbench 1. A rotating plate 4 is rotatably connected to the top of the workbench 1, which transmits the rotational force applied by the handle 13. A rotating plate 5 is rotatably connected to the top of the mounting frame 3, which works in conjunction with the rotating plate 4. The two are connected by a connecting rod 6 to form a stable transmission structure. A bending mechanism is provided on the top of the rotating plate 5. A connecting rod 6 is rotatably connected between the rotating plate 4 and the rotating plate 5, which provides stable support and motion guidance for the extrusion roller 8 and the extrusion roller 12. A quick-release mechanism is provided inside the connecting rod 6. The bending mechanism includes a gear 7, which drives the connecting rod 6 to rotate, thereby adjusting the angle of the extrusion roller 8 to facilitate material removal after bending. The gear 7 is fixedly connected to the outside of the connecting rod 6 on one side. A squeezing roller 8 is provided outside the connecting rod 6 on one side. A guide frame 9 is fixedly connected to the top of the worktable 1. It is used to provide a sliding track for the rack 10. The rack 10 is slidably connected inside the guide frame 9. A hydraulic rod 11 is fixedly connected to the top of the bracket 2. A squeezing roller 12 is provided outside the connecting rod 6. It is used to cooperate with the squeezing roller 8. Through the relative movement and squeezing action between the two, the material is bent. A handle 13 is fixedly connected to the side wall of the rotating plate 4. The connecting rod 6 on one side passes through the mounting frame 3 and extends to the outside. The top of the rotating plate 4 is rotatably connected to the bottom of the mounting frame 3. The output end of the hydraulic rod 11 is connected to the rack 10. The rack 10 meshes with the gear 7. A guide frame 20 is fixedly connected to the top of the worktable 1. It is used to provide a stable installation base for the placement plate 21. The placement plate 21 is fixedly connected to the side wall of the guide frame 20. It is used to restrict and guide the material placed on the placement plate 21.

[0032] When using this equipment, the material is first placed inside the placement plate 21. The placement plate 21 provides a stable initial placement platform for the material, ensuring that the material is in a suitable position before entering the bending process. The material is then fixed by passing through the gap between the second extrusion roller 12 and the first extrusion roller 8. The first extrusion roller 8 and the second extrusion roller 12 cooperate with each other to achieve the bending operation of the material through extrusion. The handle 13 is rotated by gripping it. The handle 13 serves as the part where the operator directly applies force, making it convenient for the user to operate and control the device. This rotates the first rotating plate 4, which is one of the key components of the transmission. Driven by the handle 13, the first rotating plate 4 begins to move. Through the connection of the connecting rod 6, the second rotating plate 5 also rotates synchronously. The connecting rod 6 transmits power and maintains the coordination of the movement of the first rotating plate 4 and the second rotating plate 5. The function is to ensure that the two can work together stably. Rotating plate 4 and rotating plate 5 rotate around the connecting rod 6 on one side, thereby driving the extrusion roller 12 to move and extrude and bend the material between the extrusion roller 12 and the extrusion roller 8, thereby adjusting the bending angle of the material. After bending is completed, the hydraulic rod 11 is activated. As a power supply device, the hydraulic rod 11 can output a stable and large thrust, which drives the rack 10 to drive the gear 7 to rotate. The combination of rack 10 and gear 7 realizes the conversion from linear motion to rotational motion, causing the connecting rod 6 on one side to rotate, thereby driving the extrusion roller 8 to rotate as well, changing the angle of the extrusion roller 8. When it rotates to a certain angle, the clamping state of the material is released, making it easy to take out the material, thereby improving the operation convenience and practicality of the equipment.

[0033] Reference Figure 3 The quick-release mechanism includes a cylinder 14, which provides a stable installation space. The cylinder 14 is fixedly connected inside the connecting rod 6. A spring 15 is installed inside the cylinder 14. A slider 16 is slidably connected inside the cylinder 14, which connects the spring 15 and the locking block 17 and transmits the elastic force of the spring 15 to the locking block 17. The locking block 17 is fixedly connected to the side wall of the slider 16. A limit rod 18 is rotatably connected inside the extrusion roller 12. The limit rod 18 is slidably connected to the outside of the connecting rod 6. A groove 19 is provided inside the limit rod 18, which is used to engage or disengage with the locking block 17 to achieve quick fixing and disassembly of the extrusion roller 12. The groove 19 engages with the locking block 17. One end of the spring 15 is fixedly connected inside the cylinder 14, and the other end of the spring 15 is fixedly connected to the side wall of the slider 16.

[0034] When bending materials of different sizes is required, the extrusion roller 12 is grasped and lifted upwards. As a key component that directly contacts the material and performs the bending action, the adjustable position of the extrusion roller 12 is crucial for adapting to different material sizes. The upward lifting action drives the limiting rod 18, which transmits the displacement force of the extrusion roller 12 to the clamping block 17. The clamping block 17, under pressure, presses the slider 16 inwards. The slider 16 slides inside the cylinder 14, which provides a stable sliding track for the slider 16, restricting its direction of movement and ensuring the accuracy of its linear motion. At this time, the spring 15 deforms under pressure. Utilizing its elastic properties, the spring 15 stores energy when compressed, providing... The subsequent reset action provides power. When the locking block 17 disengages from the groove 19, the second extrusion roller 12 can be removed and replaced to accommodate materials of different sizes. After replacement, the limiting rod 18 is aligned with the connecting rod 6 and pressed down, transmitting the pressing force to the locking block 17. The locking block 17 is then pressed inward again, causing the slider 16 to compress the spring 15 and deform it. When the spring 15 loses its force and resets, it releases its stored elastic potential energy, causing the locking block 17 to engage with the groove 19, thereby fixing the second extrusion roller 12. This ensures that the second extrusion roller 12 remains stable during operation and does not loosen or shift, guaranteeing the reliability of the bending operation. Through the above structure, the practicality and versatility of the equipment are improved.

[0035] Working principle: When using this equipment, first place the material inside the placement plate 21 and pass it through the gap between the second extrusion roller 12 and the first extrusion roller 8 to fix the material. Then, hold the handle 13 and rotate it to drive the first rotating plate 4 to rotate. Through the connection of the connecting rod 6, the second rotating plate 5 also rotates synchronously. The first rotating plate 4 and the second rotating plate 5 rotate around the connecting rod 6 on one side, thereby driving the second extrusion roller 12 to move and extrude and bend the material between the second extrusion roller 12 and the first extrusion roller 8. After bending is completed, start the hydraulic rod 11 to push the rack 10 to drive the gear 7 to rotate, so that the connecting rod 6 on one side rotates and drives the first extrusion roller 8 to rotate as well. When it rotates to a certain angle, release the clamping state of the material to facilitate the removal of the material. Through the above structure, the bending angle can be adjusted as needed.

[0036] When bending materials of different sizes is required, the pressure roller 12 is grasped and lifted upwards, causing the limiting rod 18 to press the clamping block 17. The clamping block 17 is forced to press the slider 16 inwards, causing the slider 16 to slide inside the cylinder 14. At this time, the spring 15 is deformed by the force. When the clamping block 17 disengages from the groove 19, the pressure roller 12 is removed and replaced. After replacement, the limiting rod 18 is aligned with the connecting rod 6 and pressed downwards. The clamping block 17 is forced to press inwards again, causing the slider 16 to press the spring 15 and deform. When the spring 15 loses the force and resets, it causes the clamping block 17 to engage with the groove 19, fixing the pressure roller 12. The above structure improves the applicability of the equipment.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
