Technical Field
[0001] This utility model relates to the field of feeding device technology, specifically an automatic feeding device for metal sheet processing. Background Technology
[0002] Metal sheet is a type of metal sheet with a certain thickness and width, produced through processes such as rolling. It is commonly used in industries such as construction, machinery manufacturing, automobiles, and home appliances. It has good mechanical properties, machinability, and corrosion resistance. It can be cut, bent, stamped, and processed according to different needs, and is widely used in the manufacture of various structural components, parts, and decorative materials. The use of a feeding device during the processing of metal sheets is mainly to improve production efficiency, reduce manual labor intensity, reduce human error, and ensure the stability and consistency of the processing. The feeding device can automatically and accurately transport the metal sheets to the designated position of the processing equipment, realize automated production, thereby improving the overall processing quality and efficiency, and adapting to the needs of modern industrial large-scale production. During the feeding process of metal sheets, when the equipment starts from a stationary state or stops from a moving state, the metal sheet will often be displaced along the direction of movement due to inertia. Although this displacement seems small, it may cause a series of problems in a high-precision processing environment. The most direct impact is that the position of the sheet will be deviated, making it impossible to place it accurately in the predetermined processing position. Existing technology uses mechanical clamping, but due to the inertia of the metal sheet, mechanical wear will occur due to the impact force of inertia after long-term use, resulting in gaps, which is not conducive to long-term positional accuracy control. Therefore, an automatic feeding device for metal sheet processing is proposed to address the above problems. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: An automatic feeding device for processing metal sheets includes a worktable and a linear motor. A load-bearing platform assembly is fixedly connected to the upper end of the linear motor. A metal sheet is clamped at the upper end of the load-bearing platform assembly. Hydraulic oil control components are fixedly connected to both sides of the load-bearing platform assembly. The load-bearing platform assembly includes an arch frame with an oil storage tank at its upper end. A guide rod is slidably connected to the inner side of the oil storage tank, and a first rubber sealing ring is fixedly connected to the outer side of the guide rod. A spring is fixedly connected to one end of the guide rod. The hydraulic oil control component includes a cylindrical shell with a solenoid valve fixedly connected to one end. A column plate is slidably connected to the inner side of the cylindrical shell, and a second rubber sealing ring is fixedly connected to the outer side of the column plate.

[0016] Please see Figures 1-7 This utility model provides a technical solution: An automatic feeding device for processing metal sheets includes a worktable 1 and a linear motor 2. A load-bearing platform assembly 3 is fixedly connected to the upper end of the linear motor 2. A metal sheet 4 is clamped at the upper end of the load-bearing platform assembly 3. Hydraulic oil control components 5 are fixedly connected to both sides of the load-bearing platform assembly 3. The load-bearing platform assembly 3 includes an arch frame 31. An oil storage tank 33 is opened at the upper end of the arch frame 31. A guide rod 34 is slidably connected to the inner side of the oil storage tank 33. A first rubber sealing ring 35 is fixedly connected to the outer side of the guide rod 34. A spring 36 is fixedly connected to one end of the guide rod 34. The hydraulic oil control component 5 includes a cylindrical shell 51. A solenoid valve 52 is fixedly connected to one end of the cylindrical shell 51. A column plate 53 is slidably connected to the inner side of the cylindrical shell 51. A second rubber sealing ring 54 is fixedly connected to the outer side of the column plate 53. A pull rod 55 is fixedly connected to one end of the column plate 53.
[0017] As a further implementation of this solution, the front and rear ends of the workbench 1 are fixedly connected to the linear motor 2, and the upper end of the linear motor 2 is fixedly connected to the arch frame 31. Through the above settings, the overall robustness of the device is improved, and the positional accuracy of the metal sheet during the processing is ensured. As a further implementation of this solution, a rotating groove is provided at the lower end of the arch frame 31, and a roller 32 is rotatably connected to the lower end of the arch frame 31. The roller 32 rolls on the upper end of the worktable 1. Through the above arrangement, the friction is reduced, and at the same time, it plays a supporting role for the metal plate 4, thereby improving the stability and accuracy of the movement. As a further implementation of this solution, a metal plate 4 is placed on the upper end of the arch frame 31, and a clamping plate 37 is fixedly connected to the end of the guide rod 34 away from the spring 36. The front and rear ends of the metal plate 4 are both clamped by the clamping plate 37. Through the above settings, the hydraulic principle is used to achieve clamping, which reduces wear caused by inertial impact and improves the reliability of clamping and the stability of long-term use. As a further implementation of this solution, the guide rod 34 extends out of the outer side of the oil reservoir 33, the outer side of the first rubber sealing ring 35 is in contact with the inner side of the oil reservoir 33, one end of the spring 36 is fixedly connected to the inside of the oil reservoir 33, the oil reservoir 33 and the cylinder shell 51 are both filled with hydraulic oil, the solenoid valve 52 is fixedly connected to the arch frame 31, and the solenoid valve 52 and the arch frame 31 are sealed by a rubber gasket. Through the above settings, the sealing performance of the hydraulic oil is ensured, hydraulic oil leakage is prevented, the reliability and service life of the device are improved, and the fixed connection of the spring 36 further enhances the stability of the structure. As a further implementation of this solution, the pull rod 55 extends out of the outer side of the cylinder shell 51, and the outer side of the second rubber sealing ring 54 fits against the inner side of the cylinder shell 51. With the above arrangement, the design of the pull rod 55 can make the two clamping plates 37 move away from each other when the pull rod 55 is pushed to move in the direction of the arch frame 31, thereby facilitating the positioning of the metal plate 4.
[0018] Workflow: When fixing the metal plate 4, the hydraulic oil inside the cylinder shell 51 is stored in the oil reservoir 33. Both clamping plates 37 are away from the arch frame 31. The metal plate 4 is placed on the upper end of the arch frame 31, and the solenoid valve 52 is opened. At this time, under the elastic force of the spring 36, the guide rod 34 is pulled to move. The guide rod 34 is retracted into the roller 32. The guide rod 34 drives the clamping plates 37 to clamp the metal plate 4. If there is a gap between the front or rear clamping plates 37 and the metal plate 4, the pull rod 55 is pulled by hand to move away from the cylinder shell 51. The pull rod 55 drives the column plate 53 to move. The second rubber sealing ring 54 seals the column plate 53 and the cylinder shell 51. At the same time, the first rubber sealing ring 35 seals the guide rod 34 and the arch frame 31 to prevent hydraulic oil from overflowing. Under the suction of the column plate 53, the front... Hydraulic oil from the oil reservoir 33 at one or both ends enters the cylinder shell 51. Under negative pressure, the gapped clamping plate 37 pushes the metal plate 4, causing both clamping plates 37 to be tightly pressed against the metal plate 4. When multiple solenoid valves 52 are closed simultaneously, the hydraulic oil inside the oil reservoir 33 cannot flow, thus fixing the guide rod 34 and the clamping plate 37. When controlling the metal plate 4 to move to the predetermined position for processing, the linear motor 2 controls the movement of the load-bearing platform assembly 3. At this time, the roller 32 rolls on the upper end of the worktable 1, thereby displacing the metal plate 4. Based on the above principles, the device changes the traditional mechanical fixing method. This significantly reduces mechanical wear caused by inertia when displacing the metal plate 4, ensuring that the device can still stably position the metal plate 4 during long-term use.
[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
