Description

Technical Field

[0001] This utility model relates to the field of metal bending technology, and in particular to a metal bending device. Background Technology

[0002] In modern manufacturing, metal products are widely used in aerospace, automobile manufacturing, construction engineering, and many other fields. Metal bending, as a crucial step in metal processing, directly impacts product performance and production cycles in terms of processing quality and efficiency. With the increasingly diversified demands for metal products across industries, higher requirements are being placed on the functionality and precision of metal bending equipment. Traditional metal bending equipment often employs simple die stamping or manual bending methods. Such equipment can typically only achieve bending at specific angles or shapes, and is insufficient for complex shapes, such as bending a metal rod all the way around. In actual production, when manufacturing ring-shaped metal parts or spiral metal structures, traditional equipment is not only inefficient but also suffers from significant human error during operation, making it difficult to control angle deviations. This results in products with dimensions and shapes that do not meet standards, increasing scrap rates, affecting subsequent assembly processes, and causing cost waste.

[0003] The inventors believe that the following defects often exist: when workers bend heated metal rods, the equipment can only achieve bending at specific angles or shapes, making it difficult to meet the special requirements of bending all the way, and the angle is prone to deviation, resulting in the product size and shape not meeting the standard requirements, thus affecting product quality and subsequent assembly problems; therefore, a metal bending equipment is proposed to address the above problems. Summary of the Invention

[0027] Reference Figure 1-5As shown, this utility model provides a technical solution: a metal bending device, including an operating table 1, an electric cylinder 2 fixedly connected to the surface of the operating table 1, a lead screw 3 fixedly connected to the output end of the electric cylinder 2, a toothed plate 4 fixedly connected to one end of the lead screw 3, a support block 6 fixedly connected to the surface of the operating table 1, a toothed ring 5 rotatably connected to the arc surface of the support block 6, the toothed ring 5 meshing with the surface of the toothed plate 4, a support plate 7 slidably connected to the arc surface of the support block 6, the support plate 7 fixedly connected to the surface of the toothed ring 5, a bending frame 8 fixedly connected to the surface of the support plate 7, the bending frame 8 slidably connected to the surface of the support block 6, a shaping rod 9 fixedly connected to the surface of the support block 6, and a positioning rod 10 fixedly connected to the surface of the support block 6. A heated metal rod is placed on the support block 6. Located between the shaping rod 9 and the positioning rod 10, the electric cylinder 2 is activated. The electric cylinder 2 drives the lead screw 3 to reciprocate, which in turn drives the toothed plate 4 to reciprocate. The toothed plate 4 drives the toothed ring 5 to rotate on the arc surface of the support block 6. Simultaneously, the toothed ring 5 drives the support plate 7 to move, and the support plate 7 drives the bending frame 8 to rotate 360 ​​degrees against the heated metal rod. At this point, the metal rod deforms and wraps around the arc surface of the shaping rod 9, achieving the effect of bending the heated metal rod one full turn. This avoids the problem when workers bend the heated metal rod, as the equipment can only achieve bending at specific angles or shapes, making it difficult to meet the special requirement of bending one full turn. Furthermore, the angle is prone to deviation, resulting in the product's size and shape not meeting standard requirements, thus affecting the product's performance. The quality and subsequent assembly issues have improved the versatility of the device. Two sliding rods 11 are fixedly connected to the surface of the operating table 1. A clamping frame 12 is slidably connected to the arc surfaces of the two sliding rods 11. A first spring 13 is fitted onto the arc surfaces of the sliding rods 11. Both ends of the first spring 13 are fixedly connected to the clamping frame 12 and the sliding rod 11, respectively. A clamping rod 14 is slidably inserted into the clamping frame 12. A clamping plate 15 is fixedly connected to one end of the clamping rod 14. When the operator places the heated metal rod into the clamping frame 12 and presses the clamping rod 14, the clamping rod 14 moves to the end fixedly connected to the clamping plate 15. The clamping plate 15 causes the metal rod to press against the surface of the support block 6, stretching the first spring 13. At this point, the heated metal rod is pressed, clamped, and fixed to the surface of the support block 6. To reduce direct contact between the worker's palm and the heated metal rod during bending, thus minimizing the risk of burns, a push handle 16 is fixedly connected to one end of the clamping rod 14. The surface of the push handle 16 has several anti-slip protrusions. When the worker needs to press the clamping rod 14, they can move it by pressing the push handle 16. The push handle 16 facilitates operation, and the anti-slip protrusions improve stability during operation. A second spring 18 is fitted onto the arc-shaped surface of the clamping rod 14. Both ends of the second spring 18 are fixedly connected to the push handle 16 and the clamping frame 12, respectively. When the worker releases the push handle 16, releasing the pressure of the clamping plate 15 on the heated metal rod, the rebound force of the second spring 18 causes the push handle 16 to move upwards.The device achieves automatic reset of the push handle 16 and clamping plate 15, reducing the number of steps required for operation and improving worker efficiency. A heat insulation pad 17, made of ceramic fiber, is fixedly connected to the side of the clamping plate 15 away from the clamping rod 14. This pad effectively isolates the heat from the heated metal rod, preventing heat transfer to the push handle 16 and thus avoiding burns to workers. A positioning plate 19 is fixedly connected to the arc surface of the slide rod 11. The surface of the positioning plate 19 slides against the clamping frame 12, thus positioning the clamping frame 12. The purpose of this design is to ensure that the heated metal rod falls accurately onto the surface of the support block 6, reducing unnecessary operations by the workers. A feeding rack 20 is fixedly connected to one side of the clamping frame 12. A feeding rod 21 is slidably inserted into the feeding rack 20, and a circular plate 22 is fixedly connected to one end of the feeding rod 21. The worker places the heated metal rod into the feeding rack 20 and pushes the feeding rod 21, causing it to slide within the rack. Simultaneously, the feeding rod 21 drives the circular plate 22 to push the heated metal rod into the clamping frame 12. This achieves the effect of convenient feeding by workers, thereby improving their work efficiency.

[0028] Working principle: During use, the operator first places the heated metal rod into the loading rack 20 and pushes the loading rod 21. The loading rod 21 drives the circular plate 22 to send the metal rod into the clamping frame 12. Since the positioning plate 19 on the sliding rod 11 positions the clamping frame 12, it can ensure that the metal rod can accurately land on the surface of the support block 6. Next, the clamping rod 14 is pressed by the push handle 16. The clamping rod 14 drives the clamping plate 15 to press down on the metal rod, so that it abuts against the support block 6. At this time, the first spring 13 is stretched to achieve pressing and clamping of the metal rod, reducing the risk of burns from direct contact with the high-temperature metal rod. At the same time, the ceramic fiber heat insulation pad 17 on the clamping plate 15 effectively insulates the heat and prevents burns. After the fixing is completed, the electric cylinder 2 is started. The electric cylinder 2 drives the lead screw 3 to move back and forth. The lead screw 3 then drives the toothed plate 4 to move. The toothed plate 4 and the... The toothed ring 5 engages, causing it to rotate on the arc surface of the support block 6. As the toothed ring 5 rotates, it drives the support plate 7 connected to it. The support plate 7 then drives the bending frame 8 to press against the metal rod and rotate 360 ​​degrees around the support block 6. During this process, the metal rod deforms under the action of the bending frame 8 and wraps around the arc surface of the shaping rod 9, completing one round of bending. After bending is completed, the push handle 16 is released, and the rebound force of the second spring 18 drives the push handle 16 and the clamping plate 15 to automatically reset, releasing the clamp on the metal rod. Throughout the process, the first spring 13 sleeved on the slide rod 11 assists the clamping frame 12 to reset. The clamping frame 12 slides on the slide rod 11, preparing for the next feeding and bending. Through the coordinated operation of multiple components, the equipment not only meets the special requirement of bending the metal rod one round, but also improves the safety and efficiency of operation.
