Description
Technical Field
[0001] This utility model relates to the field of spring bending technology, and in particular to a spring bending adjustment device. Background Technology
[0002] In various industries such as machinery manufacturing, hardware processing, and construction, springs are important basic components, and their processing quality directly affects the performance and service life of the products. Spring bending and bending at spring joints are key steps in the spring processing, playing a decisive role in the spring's shape, dimensional accuracy, and mechanical properties.
[0003] When bending springs manually, operators rely mainly on experience and feel to control the bending angle and force. This method is not only inefficient but also makes it difficult to ensure consistency and accuracy. When different degrees of curvature are required for the springs, controlling and positioning the bending degree is particularly difficult, often resulting in large deviations in the bending angle that do not meet the usage requirements. This forces workers to perform repeated bending operations, increasing their workload and material waste.
[0004] The inventors believe that the following defects often exist: when workers need to bend raw materials to different degrees of curvature, the degree of bending is often difficult to control or position, resulting in bending of the raw materials that does not meet the usage requirements. Workers have to perform bending operations multiple times to meet the usage requirements, thus increasing the workload of workers. Therefore, a spring bending device is proposed to address the above problems. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies where bending of raw materials does not meet usage requirements, forcing workers to perform multiple bending operations to satisfy these requirements, thus increasing their workload. Therefore, this invention proposes a spring-loaded bending device.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a spring bending device, comprising an operating table, the surface of which is provided with a bending device, the bending device comprising two rotating frames, both of which are fixedly connected to the surface of the operating table, a bending cylinder rotatably connected to one side of the two rotating frames that are close to each other, an insertion hole being provided on the arc surface of the bending cylinder, a rotating head being fixedly connected inside the bending cylinder, the arc surface of the rotating head being rotatably connected to the two rotating frames, a fixing rod being fixedly connected to one side of the operating table, an operating plate being slidably connected to the arc surface of the fixing rod, an octagonal rod being fixedly connected to one side of the operating plate, and an octagonal groove being provided on the surface of the rotating head.
[0007] The effect achieved by the above-mentioned components is as follows: by setting up a bending device, it is possible to bend raw materials that need to be bent to different degrees, thus avoiding the situation where the degree of bending is often difficult to control or position when workers need to bend raw materials to different degrees, resulting in bending of raw materials that does not meet the usage requirements. This would force workers to perform bending operations multiple times to meet the usage requirements, thereby increasing the workload of workers and improving the practicality of the device.
[0008] Preferably, a limiting plate is fixedly connected to the end of the fixed rod away from the operating table, and the size of the octagonal rod is adapted to the size of the octagonal groove of the rotating head.
[0009] The effect achieved by the above components is that the limiting plate restricts the maximum sliding distance of the operating plate on the arc surface of the fixed rod, thus preventing the operating plate from detaching from the arc surface of the fixed rod due to excessive pulling force when the operator pulls it.
[0010] Preferably, a first spring is fitted onto the arc surface of the fixing rod, and the two ends of the first spring are fixedly connected to the operating plate and the operating table, respectively.
[0011] The effects achieved by the above components are as follows: the first spring improves the stability of the octagonal rod when limiting the rotating head, and at the same time improves the work efficiency of the staff.
[0012] Preferably, a rubber ring is fixedly connected to the surface of the operating panel, and the rubber ring is slidably connected to the arc surface of the fixing rod.
[0013] The effect achieved by the above components is that the contraction force of the rubber ring wraps around the arc surface of the fixed rod, thereby slowing down the sliding speed of the operating plate on the arc surface of the fixed rod, thus achieving a damping effect.
[0014] Preferably, the surface of the operating table is provided with a sliding groove, and the surface of the sliding groove of the operating table is provided with a clamping device. The clamping device includes a support plate, the support plate is slidably connected to the surface of the sliding groove of the operating table, the surface of the support plate is provided with a placement hole, and two connecting plates are fixedly connected to the surface of the support plate. A drive rod is threaded into the connecting plate, and one end of the drive rod is rotatably connected to the clamping plate.
[0015] The effect achieved by the above-mentioned components is as follows: by setting up a clamping device, the bending raw material after bending and positioning is clamped and fixed, avoiding the need for workers to hold the raw material for a period of time after bending, which would affect the workers' normal work and improve the practicality of the device.
[0016] Preferably, a handle is fixedly connected to the end of the drive rod away from the clamping plate, and an anti-slip pad is fixedly connected to one side of the clamping plate.
[0017] The above components achieve the following effects: the handle facilitates the operation of the device by the staff, providing a more suitable point of leverage; and the anti-slip mat prevents the raw materials from slipping.
[0018] Preferably, a positioning rod is fixedly connected to the side of the clamping plate near the drive rod, and the arc surface of the positioning rod is slidably connected to the connecting plate.
[0019] The effect achieved by the above components is that the positioning rod restricts the clamping plate from rotating with the drive rod, so as to provide stable and accurate guidance for the clamping plate.
[0020] In summary, the beneficial effects of this utility model are as follows:
[0021] 1. In this utility model, by setting a bending device, the effect of bending raw materials with different degrees of curvature is achieved. This avoids the situation where the degree of bending is often difficult to control or position when workers need to bend raw materials with different degrees of curvature, which leads to the bending of raw materials not meeting the usage requirements. As a result, workers have to perform bending operations multiple times to meet the usage requirements, which increases the workload of workers and improves the practicality of the device.
[0022] 2. In this utility model, by setting a clamping device, the bending raw material after bending and positioning is clamped and fixed, avoiding the need for workers to hold the raw material for a period of time after bending it, which would affect the workers' normal work and improve the practicality of the device.

Detailed Implementation
[0028] Reference Figure 1 As shown, this utility model provides a technical solution: a spring bending device, including an operating table 1. The surface of the operating table 1 is provided with a bending device 2. By setting the bending device 2, the effect of bending raw materials to be bent to different degrees can be achieved. This avoids the situation where the bending degree of the raw materials is often difficult to control or position when the operator needs to bend the raw materials to different degrees, resulting in the bending of the raw materials not meeting the usage requirements. This would force the operator to perform bending operations multiple times to meet the usage requirements, thereby increasing the workload of the operator. This improves the practicality of the device. The surface of the operating table 1 is provided with a sliding groove, and the surface of the sliding groove of the operating table 1 is provided with a clamping device 3. By setting the clamping device 3, the bending and positioning of the raw materials can be clamped and fixed. This avoids the situation where the operator needs to hold the raw materials for a period of time after bending, which would affect the operator's normal work. This improves the practicality of the device.
[0029] The specific configuration and function of its bending device 2 and clamping device 3 will be explained in detail below.
[0030] Reference Figure 2 and Figure 3As shown in this embodiment: the bending device 2 includes two rotating frames 21, both of which are fixedly connected to the surface of the operating table 1. A bending cylinder 22 is rotatably connected to one side of the two rotating frames 21 that is close to each other. An insertion hole is provided on the arc surface of the bending cylinder 22. A rotating head 23 is fixedly connected inside the bending cylinder 22. The arc surface of the rotating head 23 is rotatably connected to the two rotating frames 21. A fixing rod 24 is fixedly connected to one side of the operating table 1. An operating plate 25 is slidably connected to the arc surface of the fixing rod 24. An octagonal rod 26 is fixedly connected to one side of the operating plate 24. An octagonal groove is formed on the surface of the rotating head 23. A limit plate 27 is fixedly connected to the end of the fixed rod 24 away from the operating table 1. The size of the octagonal rod 26 is adapted to the size of the octagonal groove of the rotating head 23. When the operator pulls the operating plate 25, the operating plate 25 slides on the arc surface of the fixed rod 24. At this time, the limit plate 27 achieves the effect of limiting the maximum distance of the operating plate 25 sliding on the arc surface of the fixed rod 24, thus preventing the operator from pulling the operating plate 25 due to the pulling... Excessive force caused the operating plate 25 to detach from the arc surface of the fixing rod 24. A first spring 28 is fitted onto the arc surface of the fixing rod 24, with both ends of the first spring 28 fixedly connected to the operating plate 25 and the operating table 1, respectively. When the operator releases the operating plate 25, the rebound force of the first spring 28 causes the operating plate 25 to slide on the arc surface of the fixing rod 24. Simultaneously, the operating plate 25 drives the octagonal rod 26 to move until the octagonal rod 26 inserts into the octagonal groove of the rotating head 23. At this point, the first spring 28 raises the octagonal... The stability of the lever 26 when limiting the rotating head 23 is improved, and the work efficiency of the operator is also improved. A rubber ring 29 is fixedly connected to the surface of the operating plate 25. The rubber ring 29 is slidably connected to the arc surface of the fixed rod 24. When the operator moves the operating plate 25, the operating plate 25 drives the rubber ring 29 to slide on the arc surface of the fixed rod 24. At this time, the contraction force of the rubber ring 29 wraps around the arc surface of the fixed rod 24, thereby slowing down the sliding speed of the operating plate 25 on the arc surface of the fixed rod 24, which has a damping effect.
[0031] Reference Figure 4As shown, specifically, the clamping device 3 includes a support plate 31, which is slidably connected to the surface of the sliding groove of the operating table 1. The surface of the support plate 31 has placement holes. Two connecting plates 32 are fixedly connected to the surface of the support plate 31. A drive rod 33 is threaded into the connecting plate 32. One end of the drive rod 33 is rotatably connected to a clamping plate 34. A handle 36 is fixedly connected to the end of the drive rod 33 away from the clamping plate 34. An anti-slip pad 35 is fixedly connected to one side of the clamping plate 34. The handle 36 facilitates the operation of the device by the operator, providing a more suitable operating environment. The anti-slip pad 35 is used to prevent the raw materials from slipping. A positioning rod 37 is fixedly connected to the side of the clamping plate 34 near the drive rod 33. The arc surface of the positioning rod 37 is slidably connected to the connecting plate 32. When the operator turns the handle 36, the handle 36 drives the drive rod 33 to move in the threaded motion of the connecting plate 32. At the same time, the drive rod 33 drives the clamping plate 34 to move. The clamping plate 34 drives the positioning rod 37 to slide in the connecting plate 32. At this time, the positioning rod 37 achieves the effect of limiting the clamping plate 34 to rotate with the drive rod 33, so as to provide stable and accurate guidance for the clamping plate 34.
[0032] Working principle: The octagonal rod 26 has an angle of 45 degrees. When the raw material needs to be bent, the operator first pulls the operating plate 25. The operating plate 25 slides on the arc surface of the fixed rod 24. The limiting plate 27 limits the maximum sliding distance to prevent the operating plate 25 from detaching from the fixed rod 24 due to excessive pulling force. During this process, the operating plate 25 drives the rubber ring 29 to slide on the arc surface of the fixed rod 24. The contraction force of the rubber ring 29 wraps around the fixed rod 24, slowing down the sliding speed of the operating plate 25 and providing a damping effect. As the operating plate 25 slides, the first spring 28 is stretched, and at the same time, the octagonal rod 26 disengages from the octagonal groove of the rotating head 23. Then, the operator inserts the raw material to be bent through the insertion hole on the arc surface of the bending cylinder 22 into the bending cylinder. Inside the cylinder 22, the bending cylinder 22 is rotated according to the required curvature. Since the rotating head 23 is fixedly connected inside the bending cylinder 22 and the rotating head 23 is rotatably connected to the rotating frame 21, the bending cylinder 22 can rotate smoothly and drive the raw material to bend. When the appropriate curvature is reached, the operator releases the operating plate 25. The rebound force of the first spring 28 causes the operating plate 25 to slide in the opposite direction on the arc surface of the fixed rod 24. The operating plate 25 drives the octagonal rod 26 to move until the octagonal rod 26 is inserted into the octagonal groove of the rotating head 23, thereby limiting the rotating head 23 and fixing the bending cylinder 22 and the bent raw material. At this time, the first spring 28 improves the stability of the octagonal rod 26 in limiting the rotating head 23, completing a precise bending operation and improving work efficiency.
[0033] In use, first slide the support plate 31 along the slide groove of the operating table 1 to a suitable position to prepare for clamping the raw material. When it is necessary to clamp the bent raw material, place the raw material in the placement hole on the surface of the support plate 31. Then, the operator turns the handle 36. Since the handle 36 is fixedly connected to the drive rod 33, the drive rod 33 moves in a threaded motion within the connecting plate 32. At the same time, the drive rod 33 drives the clamping plate 34 to move towards the raw material. During this process, the clamping plate 34 drives the positioning rod 37 to slide within the connecting plate 32. The positioning rod 37 restricts the clamping plate 34 from following the drive. Rotating the lever 33 causes it to move linearly in a specific direction, providing a stable and accurate guide for the clamping plate 34. As the clamping plate 34 approaches the raw material, the anti-slip pad 35 on one side contacts the raw material, increasing the friction between the anti-slip pad 35 and the raw material to prevent the raw material from slipping during clamping. Continuing to rotate the handle 36 continues until the clamping plate 34 firmly clamps the raw material, thus completing the stable clamping of the raw material. When it is necessary to release the raw material, rotating the handle 36 in the opposite direction drives the lever 33 to move the clamping plate 34 away from the raw material, making it easy to remove the processed or unprocessed raw material.
