Description

Technical Field

[0001] The present invention relates to the technical field of metal product processing, and specifically to an indentation device for metal product processing. Background Art

[0002] In the actual processing of metal products, it is often necessary to perform indentation treatment on their surfaces to achieve functions such as identification, anti-slip, positioning, or subsequent assembly guidance. Traditional metal indentation methods mostly adopt a combination of a fixed mold and a manual or semi-automatic pressing structure. Its operation process relies on manual adjustment of the indentation depth and position, not only having problems such as inaccurate positioning and uneven indentation depth, but also having low production efficiency and being difficult to meet the processing requirements of large quantities and high consistency.

[0003] Although some existing automated devices have introduced a conveying mechanism and an indentation component, problems such as workpiece deviation or unstable clamping are likely to occur during the conveying process, affecting the accuracy of the indentation position. At the same time, existing indentation equipment generally lacks the ability of automatic feedback adjustment of indentation quality. If there are differences in metal materials or thicknesses, the indentation depth is prone to fluctuate, affecting the appearance and functional consistency of the product. In addition, some detection and adjustment systems relying on electronic sensors have problems such as high cost, poor reliability, and complex maintenance, restricting their wide application in small and medium-sized enterprises.

[0004] Therefore, it is necessary to develop a metal product indentation device with a reasonable structure, stable conveying, and an automatic indentation quality adjustment function to improve the accuracy, consistency, and automation level of indentation processing and meet the technical requirements of efficient processing of modern metal products.

[0005] After retrieval, it is found that the prior art publication number CN222001576U discloses an indentation device for metal product processing, including support columns, gaskets, cross plates, indentation mechanisms, clamping mechanisms, movable mechanisms, and bottom plates. Gaskets are arranged on the lower sides of the support columns, cross plates are arranged on the upper sides of the support columns, indentation mechanisms are arranged inside the cross plates, clamping mechanisms are arranged below the cross plates, the clamping mechanisms are located below the indentation mechanisms, the support columns and gaskets are located in front of and behind the clamping mechanisms, and movable mechanisms are arranged inside the clamping mechanisms. In this solution, the metal product to be processed is placed on the placement groove, the two connecting rods on both sides push the upper connecting rod one to move, and the connecting rod one then pushes the clamping blocks to move towards each other to clamp the metal product. The clamping blocks can clamp metal products of different sizes without manual adjustment, increasing the practicability of the indentation device for metal product processing.

[0006] Therefore, based on the above retrieval and in combination with the existing technology, an existing indentation device for metal product processing does not have any indentation depth feedback or adjustment mechanism. When the indentation mechanism performs the indentation task, it only relies on the mechanical pressing action and cannot achieve adaptive adjustment according to the material and thickness differences of metal products, which easily leads to uneven indentation depths, affecting the indentation consistency and appearance quality. At the same time, it lacks automation and intelligent adjustment capabilities. In this solution, the indentation and clamping processes entirely rely on the mechanical structure transmission, without involving detection, feedback, or closed-loop control design, and cannot achieve automatic identification, real-time compensation, or adjustment of indentation parameters. The degree of automation is low, and it is difficult to meet the diverse and high-precision processing requirements. Summary of the Invention

[0047] Please refer to Figure 5 , Figure 6 , The rotating assembly 6 includes a driven gear 61 and a driving gear 62. The driven gear 61 is coaxially and fixedly installed on the front end face of the rotating installation cylinder 5. Specifically, the driven gear 61 is coaxially and fixedly installed on the outer wall of the rotating cylinder 51. The outer wall of the rotating cylinder 51 is provided with ridges, and the inner wall of the driven gear 61 is provided with grooves. The ridges have a limiting effect on the grooves, enabling the rotating cylinder 51 to rotate synchronously with the driven gear 61. The driven gear 61 and the driving gear 62 are meshed and clamped. The driving gear 62 is coaxially and fixedly installed with a third motor 63. Specifically, the model of the third motor 63 is 573S15. The third motor 63 is fixedly installed on the inner wall of the mounting frame 11. By driving the driving gear 62 to rotate through the third motor 63, the driving gear 62 drives the driven gear 61 to rotate, indirectly driving the rotating installation cylinder 5 to rotate synchronously, so as to switch the indentation assembly 7 or the detection assembly 8 in contact with the metal product. Two sliding rails 52 are symmetrically arranged on the upper and lower inner walls of the rotating installation cylinder 5. The indentation assembly 7 and the detection assembly 8 are respectively slidably installed on the inner walls of the two sliding rails 52.

[0048] Embodiment 3: Please refer to Figures 4 to 12, an indentation device for metal product processing. The indentation assembly 7 includes a first sliding plate 71. The outer wall size of the first sliding plate 71 is adapted to the inner wall size of the sliding rail 52. The first sliding plate 71 is slidably installed on the inner wall of the sliding rail 52. Specifically, a number of sliding strips are equidistantly provided on the left and right outer walls of the first sliding plate 71, and a number of sliding grooves are equidistantly provided on the left and right inner walls of the sliding rail 52. The number of sliding strips are respectively slidably inserted into the number of sliding grooves, so that the first sliding plate 71 can only move up and down inside the sliding rail 52. A number of force-bearing seats 711 are equidistantly provided on the top surface of the first sliding plate 71. The positions of the number of force-bearing seats 711 correspond to the positions of the number of hydraulic cylinders 44. Specifically, pressure-applying ends are installed at the telescopic ends of the number of hydraulic cylinders 44, and the force-bearing seats 711 are pressured through the pressure-applying ends. A number of adjusting cylinders 72 are equidistantly installed on the bottom surface of the first sliding plate 71. Silicone oil is filled inside the number of adjusting cylinders 72. Specifically, silicone oil still maintains fluidity at low temperatures, is not easy to solidify, and has a low friction coefficient, making it suitable as a lubricant. A number of adjusting rods 725 are slidably inserted into the number of adjusting cylinders 72. The bottom ends of the number of adjusting rods 725 are fixedly installed with an indentation die 73 for indentation of the metal mold. A water inlet pipe 721 is provided at the top end of the outer wall of the adjusting cylinder 72. A ball valve 722 is slidably installed inside the water inlet pipe 721. A spring 723 is fixedly installed on the outer wall of the ball valve 722. Specifically, please refer to Figure 12 , an abutting ring is provided at the end of the water inlet pipe 721. The outer wall of the ball valve 722 abuts against the inner wall of the abutting ring. A fixing ring is provided on the inner wall of the water inlet pipe 721. One end of the spring 723 away from the ball valve 722 is fixedly connected to the fixing ring. The spring 723 releases elastic force to tightly abut the ball valve 722 against the inner wall of the abutting ring. A second connecting rope 724 is connected to the outer wall of the ball valve 722. The end of the second connecting rope 724 away from the ball valve 722 passes through the top surface of the adjusting cylinder 72 and the first sliding plate 71 and then is connected to the first connecting rope 43.

[0049] Please refer to Figures 4 to 12, the detection component 8 includes a second sliding plate 81. The outer wall dimensions of the second sliding plate 81 are adapted to the inner wall dimensions of the sliding rail 52. The second sliding plate 81 is slidably installed on the inner wall of the sliding rail 52. Specifically, a number of sliding strips are equidistantly arranged on the left and right outer walls of the second sliding plate 81, and a number of sliding grooves are equidistantly arranged on the left and right inner walls of the sliding rail 52. The number of sliding strips are respectively slidably inserted into the number of sliding grooves, so that the second sliding plate 81 can only move up and down inside the sliding rail 52. Fixing plates 53 are provided at the ends of the two sliding rails 52 close to the outer wall of the rotating mounting cylinder 5. The fixing plates 53 have a limiting effect to prevent the indentation component 7 and the detection component 8 from falling off the sliding rail 52. A number of induction seats 811 are equidistantly arranged on the bottom surface of the second sliding plate 81. The positions of the number of induction seats 811 correspond to the positions of the number of hydraulic cylinders 44. Specifically, pressure application ends are installed at the telescopic ends of the number of hydraulic cylinders 44, and the induction seats 811 are pressured through the pressure application ends. A corrugated sleeve 82 is fixedly installed on the top surface of the second sliding plate 81. Silicone oil is stored inside the inner wall of the corrugated sleeve 82. Specifically, silicone oil remains fluid at low temperatures, is not easy to solidify, and has a low friction coefficient, making it suitable as a lubricant. The top surface of the corrugated sleeve 82 is a rigid plate, and a detection film 83 is fixedly installed on the top surface of the rigid plate. A communication hole is opened on the top surface of the rigid plate, and the inside of the corrugated sleeve 82 is communicated with the detection film 83 through the communication hole. Specifically, the detection film 83 is a silicone rubber film. The silicone rubber film has excellent elastic deformation ability, can withstand large deformations without breaking, can completely return to its original shape after the external force is removed, and also has excellent flexibility, maintains good mechanical strength even at extremely thin thicknesses, can closely fit complex surface contours, and also has stable chemical inertness, is resistant to oil and grease, acid and alkali corrosion, does not react with common industrial media, and has even more durable mechanical durability, can withstand long-term repeated compression deformations without permanent deformation or performance degradation. The rigid plate is fixedly connected to the fixing plate 53. When the corrugated sleeve 82 is in a normal state, the detection film 83 blocks the communication hole, and the silicone oil cannot be discharged from the corrugated sleeve 82. When the corrugated sleeve 82 is compressed, the silicone oil enters the inside of the detection film 83 through the communication hole, causing the detection film 83 to deform and filling and detecting the grooves of the metal product. A number of water guide pipes 84 are equidistantly installed at the bottom end of the outer wall of the corrugated sleeve 82. The number of water guide pipes 84 are communicated with the inside of the corrugated sleeve 82. One ends of the number of water guide pipes 84 away from the corrugated sleeve 82 are respectively fixedly connected to the water inlet pipes 721 of the number of adjusting cylinders 72. A number of wiring posts are equidistantly arranged on the bottom surface of the second sliding plate 81. One ends of the number of first connecting ropes 43 away from the second connecting rope 724 are respectively fixedly connected to the number of wiring posts. Specifically, when the indentation on the metal product by the indentation die 73 is too shallow, the detection component 8 is used to detect the indentation. Since the silicone oil inside the corrugated sleeve 82 is constant, the silicone oil inside the corrugated sleeve 82 is made to enter the detection film 83 by compressing the corrugated sleeve 82 until the outer wall of the detection film 83 is in full contact with the inner wall of the indentation. At this time, the excess silicone oil inside the corrugated sleeve 82 pressures the ball valve 722 through the water guide pipe 84, and the ball valve 722 is pushed open, compressing the compression spring 723.Excess silicone oil enters the adjustment cylinder 72, increasing the amount of silicone oil inside the adjustment cylinder 72, pushing the adjustment rod 725 downward, thereby extending the combined length of the adjustment cylinder 72 and the adjustment rod 725, making the next indentation deeper. The ball valve 722 and the spring 723 form a one-way valve, preventing the silicone oil inside the adjustment cylinder 72 from discharging. When the indentation of the indentation die 73 on the metal product is too deep, the detection assembly 8 detects the indentation. Since the silicone oil inside the corrugated sleeve 82 is constant, the silicone oil inside the corrugated sleeve 82 enters the detection film 83 by compressing the corrugated sleeve 82 until the outer wall of the detection film 83 is in full contact with the inner wall of the indentation. At this time, too much silicone oil has been discharged from the corrugated sleeve 82, the second sliding plate 81 drives the end of the first connecting rope 43 downward, the surplus of the first connecting rope 43 is used, the first connecting rope 43 is straightened, the end of the first connecting rope 43 away from the second sliding plate 81 pulls the second connecting rope 724, the second connecting rope 724 pulls the ball valve 722, causing the ball valve 722 to disengage from the abutting ring, compressing the spring 723, and discharging the excess silicone oil inside the adjustment cylinder 72 into the corrugated sleeve 82 through the water guide pipe 84, thereby shortening the combined length of the adjustment cylinder 72 and the adjustment rod 725 and making the next indentation shallower.

[0050] The working principle of the present invention is as follows: When the device is in use, first, the metal product is conveyed by the conveyor belt 2 installed inside the mounting frame 11. The conveyor belt 2 is driven by the first motor 21. Two groups of limiting components 3 are provided on both sides of the conveyor belt 2. Each group of limiting components 3 is composed of a rotating rod 31, a mounting plate 311, a bearing, a pressure roller 32, and a second motor 33. The pressure roller 32 is made of rubber and has a patterned structure, clamping the metal product in cooperation with the conveyor belt 2, providing stable guidance during transportation, and preventing the workpiece from running off track. The rotating rod 31 is connected to the second motor 33 through a transmission belt 34 to achieve the active rotation of the pressure roller 32, effectively improving the clamping force and transportation efficiency.

[0051] After the metal product is sent directly below the fixing component 4, the first motor 21 and the second motor 33 stop working, and the rotating component 6 installed on the front end face of the rotating mounting cylinder 5 is started. The third motor 63 is started, the driving gear 62 is driven to rotate by the third motor 63, the driven gear 61 is driven to rotate by the driving gear 62, indirectly driving the rotating mounting cylinder 5 to rotate synchronously. Two sliding rails 52 are symmetrically arranged on the inner wall of the rotating mounting cylinder 5. The indentation component 7 and the detection component 8 are respectively slidably installed in their respective sliding grooves. By rotating the rotating mounting cylinder 5, the indentation component 7 and the detection component 8 can alternately contact the metal product, alternately completing the indentation and detection tasks.

[0052] When the mounting cylinder 5 is rotated to rotate the indentation assembly 7 to the position aligned with the metal product, the hydraulic cylinders 44 are extended and driven to press the upper pressure end downwards. During the pressing process, the pressure is transmitted to the first sliding plate 71 through the force bearing seat 711, and then the first sliding plate 71 drives the adjusting cylinder 72 and the indentation mold 73 at the lower part thereof to move downwards, and the surface of the metal product is indented by the indentation mold 73.

[0053] The regulating cylinder 72 is pre-filled with silicone oil, which has excellent low-temperature fluidity and lubricity. An adjusting rod 725 is installed inside the regulating cylinder 72 and connected to the indentation mold 73. A water inlet pipe 721 is installed on the top of the regulating cylinder 72. A one-way valve composed of a ball valve 722 and a spring 723 is installed inside the water inlet pipe 721. A feedback loop is formed between the regulating cylinder 72 and the detection component 8 through the first connecting rope 43 and the second connecting rope 724 to realize closed-loop control of the indentation depth.

[0054] When the indentation is completed, the rotating installation cylinder 5 rotates the detection component 8 to the top of the metal product. The second sliding plate 81 slides downward under the pressure of the hydraulic cylinder 44. The second sliding plate 81 compresses the corrugated sleeve 82. Silicone oil is stored inside the corrugated sleeve 82. A rigid plate and a detection film 83 are installed on the top surface of the corrugated sleeve 82. When the indentation mold 73 makes a shallow indentation on the metal product, the indentation is detected by the detection component 8. Since the silicone oil inside the corrugated sleeve 82 is constant, the silicone oil inside the corrugated sleeve 82 enters the detection film 83 by compressing the corrugated sleeve 82. The film 83 is pressed until the outer wall of the detection film 83 is completely in contact with the inner wall of the indentation. At this time, the excess silicone oil in the corrugated sleeve 82 applies pressure to the ball valve 722 through the water guide pipe 84, and the ball valve 722 is pushed open, compressing the spring 723, and the excess silicone oil enters the regulating cylinder 72. The silicone oil in the regulating cylinder 72 increases, pushing the regulating rod 725 to move downward, thereby extending the common length of the regulating cylinder 72 and the regulating rod 725, making the next indentation deeper, and the ball valve 722 and the spring 723 form a one-way valve, so that the silicone oil in the regulating cylinder 72 cannot be discharged;

[0055] If it is detected that the indentation is too deep and too much silicone oil in the bellows sleeve 82 is pressed out, the second sliding plate 81 drives the first connecting rope 43 to tighten and pull the second connecting rope 724, so as to disengage the ball valve 722 from the abutment ring, release the pressure of the spring 723, open the channel, and allow excess silicone oil to flow back from the adjusting cylinder 72 to the bellows sleeve 82, thereby reducing the effective stroke of the adjusting rod 725 and making the indentation depth shallower, so as to achieve automatic adjustment according to the detection feedback in each cycle and realize high consistency indentation quality control; at this point, the device is completed.

[0056] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
