Description

Technical Field

[0001] This utility model relates to the field of metal product processing equipment technology, and in particular to a punching device for perforated plates. Background Technology

[0002] In the tobacco industry's warehousing process, metal tobacco frames are key containers for storing tobacco leaves. Their side walls typically need to be equipped with regularly arranged ventilation holes to ensure that the tobacco leaves are ventilated and dried.

[0003] Traditional drilling processes often employ single-point punching, which is inefficient and can only complete the processing of a single hole at a time, making it difficult to meet the needs of large-scale production.

[0004] Therefore, in view of the above situation, there is an urgent need to develop a perforation device for perforated plates to overcome the shortcomings in current practical applications. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide a punching device for perforated plates, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A perforating device for perforated plates includes a base frame with a placement platform fixedly connected to it. A receiving groove is formed on the placement platform, and a lower mold is fixedly installed within the receiving groove. Hydraulic push rods symmetrically distributed about the placement platform are also fixedly connected to the base plate of the base frame. A connecting plate is fixedly connected to the upper end of each hydraulic push rod, and a receiving plate is fixedly connected to the lower end of the connecting plate. An upper mold is detachably connected to the lower mold at the lower end of the receiving plate. Placement grooves are formed on both sides of the upper end of the placement platform, and guide rails are fixedly connected to each placement groove. Slides are symmetrically slidably connected to each guide rail. A clamping plate is fixedly connected between two corresponding slides on different guide rails, and the clamping plate abuts against the upper surface of the placement platform. A thrust assembly is also provided between the two clamping plates to control the relative movement of the two clamping plates.

[0008] In a further technical solution, the height of the clamping plate is smaller than the height of the receiving plate.

[0009] In a further technical solution, the guide rail is positioned at a height lower than the horizontal plane at the top of the placement platform.

[0010] In a further technical solution, the receiving groove is T-shaped.

[0011] In a further technical solution, the thrust assembly includes a fixed block, a threaded shaft, and a motor; a threaded shaft is rotatably connected to the inner wall of one of the placement slots, and a motor is fixedly connected to one end of the threaded shaft through the inner wall of the placement slot; fixed blocks are fixedly connected to the lower ends of the clamping plates, and the fixed blocks are threadedly connected to the threaded shafts respectively.

[0012] A further technical solution is that the threaded shaft has two threads in opposite directions, and they are respectively threadedly connected to the fixing blocks on different clamping plates.

[0013] In summary, the embodiments of this utility model have the following beneficial effects compared with the prior art:

[0014] 1. By controlling the two clamping plates to move closer to each other through the thrust assembly, the two clamping plates push the sheet metal to the middle position of the placement table, thereby fixing and clamping the sheet metal to ensure the accuracy of stamping. The hydraulic push rod is controlled to descend, and the hydraulic push rod drives the receiving plate to descend through the connecting plate. The receiving plate drives the upper mold to descend to stamp the sheet metal. It can stamp multiple holes at the same time, effectively improving stamping efficiency and meeting the needs of large-scale production.

[0015] 2. The guide rail is positioned below the horizontal plane at the top of the placement platform to prevent the sheet metal from contacting the guide rail, thereby preventing the guide rail from lifting the sheet metal upwards and affecting the stamping effect.

[0016] To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0022] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0023] like Figures 1-3 As shown, this utility model embodiment provides a drilling device for perforated plates, including a base frame 1. A placement platform 2 is fixedly connected to the base frame 1. A receiving groove 3 is formed on the placement platform 2, and a lower mold 4 is fixedly installed in the receiving groove 3. Hydraulic push rods 5, symmetrically distributed about the placement platform 2, are also fixedly connected to the base plate of the base frame 1. A connecting plate 6 is fixedly connected to the upper end of the hydraulic push rod 5, and a receiving plate 7 is fixedly connected to the lower end of the connecting plate 6. An upper mold 8 is detachably connected to the lower end of the receiving plate 7. The upper mold 8 corresponds to the lower mold 4. Placement slots 9 are provided on both sides of the upper end of the placement platform 2. Guide rails 10 are fixedly connected in each placement slot 9. Slide tables 11 are symmetrically slidably connected on each guide rail 10. Clamping plates 12 are fixedly connected between two corresponding slide tables 11 on different guide rails 10. The clamping plates 12 abut against the upper end surface of the placement platform 2. A thrust assembly 13 is also provided between the two clamping plates 12. The relative movement of the two clamping plates 12 is controlled by the thrust assembly 13.

[0024] Furthermore, the height of the clamping plate 12 is smaller than that of the receiving plate 7. When the upper mold 8 presses the sheet metal placed on the lower mold 4, it can effectively prevent the clamping plate 12 from colliding with the connecting plate 6, thereby avoiding affecting the stamping.

[0025] Furthermore, the guide rail 10 is positioned below the upper horizontal plane of the placement platform 2, thereby preventing the sheet metal from contacting the guide rail 10 and thus preventing the guide rail 10 from lifting the sheet metal upwards and affecting the stamping effect.

[0026] Furthermore, the receiving groove 3 is T-shaped, which facilitates the placement of the lower mold 4, while the waste generated during stamping can be effectively discharged.

[0027] like Figures 1-3 As shown, the thrust assembly 13 includes a fixing block 131, a threaded shaft 132, and a motor 133; the threaded shaft 132 is rotatably connected to the inner wall of one of the placement slots 9, and one end of the threaded shaft 132 is fixedly connected to the motor 133 through the inner wall of the placement slot 9. The lower ends of the clamping plates 12 are all fixedly connected to the fixing blocks 131, and the fixing blocks 131 are threadedly connected to the threaded shaft 132 respectively.

[0028] Furthermore, the threaded shaft 132 has two threads in opposite directions, and they are threadedly connected to the fixing blocks 131 on different clamping plates 12 respectively.

[0029] In a specific application, the control motor 133 is started, and then the motor 133 drives the threaded shaft 132 to rotate. After that, the two fixed blocks 131 of the threaded shaft 132 move closer or further away from each other. During this process, the slide table 11 slides along the guide rail 10. By cooperating with multiple guide rails 10 and slide table 11, the clamping plate 12 is effectively restricted to move only in a direction parallel to the guide rail 10.

[0030] In this embodiment of the invention, the two clamping plates 12 are brought closer together by the thrust assembly 13, and then the two clamping plates 12 push the sheet metal to the middle position of the placement table 2, thereby fixing and clamping the sheet metal to ensure the accuracy of stamping. The hydraulic push rod 5 is controlled to descend, and the hydraulic push rod 5 drives the receiving plate 7 to descend through the connecting plate 6. The receiving plate 7 drives the upper mold 8 to descend to stamp the sheet metal, which can stamp multiple holes at the same time, effectively improving stamping efficiency and meeting the needs of large-scale production. The guide rail 10 is positioned below the upper horizontal plane of the placement table 2, thereby avoiding contact between the sheet metal and the guide rail 10, and thus preventing the guide rail 10 from lifting the sheet metal upward and affecting the stamping accuracy.

[0031] The working principle of this utility model is as follows: The plate is placed on the placement platform 2, and then the threaded shaft 132 is rotated by the motor 133. Then the two fixing blocks 131 of the threaded shaft 132 move closer to each other until the clamping plate 12 abuts against the plate. Then the hydraulic push rod 5 is controlled to descend. The hydraulic push rod 5 drives the receiving plate 7 to descend through the connecting plate 6. The receiving plate 7 drives the upper mold 8 to descend and press the plate. Then the hydraulic push rod 5 rises and resets, thereby driving the upper mold 8 to rise. Then the motor 133 is controlled to reset, and the motor 133 drives the clamping plate 12 to reset.

[0032] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
