Description

Technical Field

[0001] The present invention relates to the field of automotive part processing, and more particularly to a bending processing device for automotive part production. Background Art

[0002] At present, with the booming development of the automotive industry, the production and manufacturing technologies of automotive parts are also continuously innovating. Among them, bending processing is a key process in the production of many automotive parts, and its processing quality and efficiency have a crucial impact on the development of the entire automotive manufacturing industry. However, there are many problems in the current bending processing of automotive parts. On the one hand, in the limiting link, the limiting method of traditional bending processing devices for automotive parts is too simple. Most rely only on basic fixed jigs and lack precise adjustment capabilities. This leads to the fact that during the actual bending process, once there are slight differences in the dimensions of the parts, or the parts are disturbed by external factors such as vibration during the operation of the equipment, the parts are extremely likely to shift. Such a shift will seriously affect the bending accuracy, resulting in large size deviations of the produced parts, making it difficult to meet the high-precision requirements of automotive assembly, thus leading to unstable product quality, increasing the defective rate, and raising the production cost. On the other hand, some of the existing technologies still use manual hand-held tools for bending, and this method has great limitations. Manual operation is greatly affected by factors such as the skill level, working state, and fatigue degree of workers. Different workers have different operation methods and forces, and even the same worker will have operation deviations due to fatigue after long-term work, which makes it impossible to guarantee the consistency of bending. For example, when producing a batch of automotive parts with the same shape, there will be obvious differences in key parameters such as bending angles and bending radii in the products bent manually, seriously affecting the stability and reliability of product quality. Moreover, the efficiency of manual bending is extremely low. Workers need to operate on each part one by one, and each bending requires a certain amount of time for positioning, applying force, etc., which is seriously out of line with the requirements of modern large-scale production. In today's automotive manufacturing industry that constantly pursues high-efficiency production, the low efficiency of manual bending has become a bottleneck restricting the expansion of production scale and is difficult to meet the rapidly growing market demand. In addition, there are also safety hazards in manual hand-held tool bending. During the operation process, workers need to be in close contact with tools and parts. Once an operation error occurs, such as the tool slipping or excessive force, it is very easy to cause harm to the workers themselves, increasing the enterprise's safety management costs and risks. Long-term engagement in this high-intensity manual operation will also cause damage to the physical health of workers, such as causing hand joint diseases and muscle strains. In summary, whether it is the deficiencies of traditional bending processing devices in the limiting link or the many problems brought by manual hand-held tool bending in the prior art, they have seriously restricted the quality and efficiency of automotive part bending processing. These problems not only increase the production cost but also reduce the product quality.

[0057] The optimal working principle of the present invention is as follows: Place the automotive parts on the feeding section 8 of the operating table 2. The operating areas 12 on both sides of the feeding section 8 facilitate the operators to load the materials. The operators adjust the limiting component 1 to make it start working, and rotate the adjusting rotary disc 19 to drive the screw rod 17 to rotate. Since the screw rod 17 is threadedly arranged on the positioning plate 18, when the screw rod 17 rotates, it will drive the movable plate 16 to move horizontally along the guide rod 20. The two movable plates 16 symmetrically arranged on both sides of the rear half section of the adjusting table 15 approach or move away from each other to precisely limit the automotive parts, ensuring the stable position of the parts during subsequent processing and preventing deviation from affecting the bending accuracy.

[0058] Start the transmission motor 75, and the transmission motor 75 drives the transmission cylinder 68 to rotate. The transmission cylinder 68 is composed of an inner cylinder 69 and an outer cylinder 70. The anti-slip grooves 72 on the outer wall of the outer cylinder 70 cooperate with the anti-slip ridges 73 on the inner side of the transmission belt 67. This structural design not only reduces the overall weight but also makes the cooperation between the transmission belt 67 and the transmission cylinder 68 more stable during transmission, so that the transmission belt 67 runs stably, and then smoothly conveys the automotive parts located at the feeding section 8 to the bending section 10. During the conveying process, the conveying support component 5 is not only responsible for conveying the parts but also can cooperate with the synchronous bending component 3 to provide reliable support for the bending operation, ensuring that the parts will not deform due to uneven stress during bending.

[0059] When the automotive parts are conveyed to the bending section 10, the synchronous bending assembly 3 starts to operate. The pressing cylinder 25 is activated, and its output end pushes the pressing seat 26 downward. The two bending cylinders 27 at the lower end of the pressing seat 26 then descend. The L-shaped bending notches 28 on the inner side of the lower half of the bending cylinder 27 are closely fitted with both sides of the bending support platform 23. When the bending notch 28 contacts the part to be bent, the two bending cylinders 27 are squeezed by the automotive parts to be bent, and thus rotate inward to bend both sides of the automotive parts. The positioning seat 30 not only facilitates the installation of the tensioning return spring 32, but also its bottom can tightly press and position the part to be bent, further improving the stability during bending. When the two bending cylinders 27 rotate in opposite directions during the bending process, the tensioning return spring 32 is stretched due to the pulling force from the bending cylinder 27, and the swing rod 37 drives the rotating support guide roller 38 to move within the arc-shaped guide opening 50. The rotating support guide roller 38 not only supports the weight of the bending cylinder 27, but also plays a guiding role, making its operation more stable.

[0060] The weight-reducing cavity 200 inside the bending cylinder 27 can reduce its own weight, lower energy consumption, improve the operating efficiency of the equipment, and enable the tensioning return spring 32 to work better, reduce the replacement frequency of the tensioning return spring 32, extend its service life, and thus reduce the usage cost. After bending, the tensioning return spring 32 can quickly reset the bending cylinder 27 to prepare for the next bending operation. In addition, the bending support seat 76 can support the automotive parts during bending; the bent automotive parts continue to move to the discharging section 11 along the conveyor belt 67, and then are discharged through the discharging assembly 6. The discharging guide member 77 is inclined, and the discharging guide groove 78 thereon guides the parts to slide down. The parts slide down along the discharging guide groove 78 and finally fall into the collecting box body 80 of the collecting assembly 7; To avoid damaging the processed parts due to the height difference, this device can automatically adjust the distance between the receiving plate 82 and the discharging guide groove 78 without any power source, saving usage and manufacturing costs and without manual intervention, preventing the distance between the discharging guide groove 78 and the receiving plate 82 from being too large, resulting in the processed parts falling from a high place and being damaged. The specific working principle is as follows: When multiple components fall onto the receiving plate 82, as the number of components increases, the weight on the receiving plate 82 increases. At this time, the receiving plate 82 moves downward. As the receiving plate 82 moves downward, the connecting column 86 also moves downward accordingly, thereby causing each inner telescopic rod 132 and outer telescopic rod 133 to swing downward simultaneously. At the same time, the inner telescopic rod 132 contracts into the outer telescopic rod 133, and each inner telescopic rod 132 and outer telescopic rod swing in opposite directions, while squeezing the second return spring 300. At the same time, the inner sleeve 88 contracts into the outer sleeve 100, and the first return spring 89 is squeezed. In this way, as the weight on the receiving plate 82 increases gradually with the increase in the number of components, the receiving plate 82 moves downward slowly to load more components. After being filled, the aggregate assembly 7 can be removed. When the components inside the aggregate assembly 7 are taken out, the weight on the receiving plate 82 gradually decreases. At this time, the first return spring 89 rebounds, causing the receiving plate 82 to rise. As the receiving plate 82 rises, the distance between the components at the bottom of the aggregate box 80 and the operator is shortened, making it more convenient for the operator to take out the components located at the bottom of the aggregate box 80 and more labor-saving. As the receiving plate 82 rises through the first return spring 89, the inner telescopic rod 132 and the outer telescopic rod 133 also swing upward to return to their positions. At the same time, under the action of the second return spring 300, the inner telescopic rod 132 extends, realizing the return of the receiving plate 82.
