[0021] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.
[0022] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments disclosed in the following specification.
[0023] Embodiment 1: As Figures 1-5 shown, the present utility model provides a limiting mechanism for a stamping device used in the production of punched enclosures, including a top plate 1. A first support plate 3 is fixedly connected to the bottom of the top plate 1 near the left side. A first limiting groove 31 is formed on the right surface of the first support plate 3. A travel switch 32 is arranged at the bottom of the first limiting groove 31. A second support plate 4 is fixedly connected to the bottom of the top plate 1 near the right side. A second limiting groove 41 is formed on the left surface of the second support plate 4. A fixed plate 45 is fixedly connected to the bottom of the second limiting groove 41. Two dampers 43 are symmetrically arranged on the top of the fixed plate 45. Springs 44 are sleeved on the outer surfaces of the two dampers 43. The top of the two dampers 43 is fixedly connected to a movable plate 42. One end of the spring 44 is fixedly connected to the bottom of the movable plate 42. A hydraulic cylinder 11 is installed on the top of the top plate 1. The telescopic end of the hydraulic cylinder 11 is fixedly connected to a mounting plate 2. A first limiting plate 21 is fixedly connected to the outer surface of the left side of the mounting plate 2. The outer surface of the first limiting plate 21 is slidably fitted with the inner wall of the first limiting groove 31. A second limiting plate 22 is fixedly connected to the outer surface of the right side of the mounting plate 2. The outer surface of the second limiting plate 22 is slidably fitted with the inner wall of the second limiting groove 41. A first connecting plate 33 is fixedly connected to the bottom of the first support plate 3. A second connecting plate 46 is fixedly connected to the bottom of the second support plate 4.
[0024] The effect achieved by the entire Example 1 is that when using this device, the device is installed on the workbench through the first connecting plate 33 and the second connecting plate 46. Then, the hydraulic cylinder 11 on the top plate 1 is started. Under the action of the hydraulic cylinder 11, the telescopic end of the hydraulic cylinder 11 will drive the mounting plate 2 to move downward. When moving, it will drive the first limiting plate 21 on the left and the second limiting plate 22 on the right to move simultaneously. At this time, it will also drive the stamping head 5 at the bottom of the mounting plate 2 to stamp downward. When the stamping head 5 stamps to the maximum stroke, the second limiting plate 22 will squeeze the movable plate 42 inside the second limiting groove 41. At this time, the damper 43 and the spring 44 at the bottom of the movable plate 42 will contract under the downward squeezing force, thereby driving the movable plate 42 to contract towards the fixed plate 45. This is the maximum stroke of the stamping head 5. At the same time, the first limiting plate 21 will also move downward synchronously in the first limiting groove 31. Therefore, when the first limiting plate 21 moves downward to the bottom and touches the triggering end at the top of the travel switch 32, it means that the stamping head 5 has reached the maximum stroke, and the travel switch 32 will stop the hydraulic cylinder 11 from working. This device precisely controls the stroke of the stamping head 5 through double limiting (the combination of the second limiting plate 22 and the movable plate 42, the damper 43, and the spring 44, as well as the first limiting plate 21 and the travel switch 32), ensuring that the stamping head 5 stops immediately when it reaches the maximum stroke, which not only improves the processing accuracy but also avoids damage to the workbench caused by over-travel, and can effectively improve the overall production efficiency. The first support plate 3 is for facilitating the installation of the travel switch 32, and the second support plate 4 is for facilitating the installation of the damper 43 and the spring 44.
[0025] Example 2: As Figures 1-5 shown, a mounting sleeve 51 is fixedly connected to the bottom of the mounting plate 2. The stamping head 5 is inserted into the bottom of the mounting sleeve 51. A fastening bolt 52 is arranged on the outer surface of the mounting sleeve 51. The end of the fastening bolt 52 slidably penetrates the outer surfaces of the mounting sleeve 51 and the stamping head 5 and extends to the other side. A nut 53 is threadedly connected to the end of the fastening bolt 52.
[0026] The effect achieved by the entire Example 2 is that when the stamping head 5 is damaged and needs to be replaced, the nut 53 on the mounting sleeve 51 is unscrewed, and then the fastening bolt 52 is screwed outwards to take out the damaged stamping head 5 and install a new stamping head 5. By simply unscrewing the nut 53 and the fastening bolt 52, the damaged stamping head 5 can be easily taken out and replaced with a new one. The entire replacement process is fast and convenient, which can effectively avoid the problem of reduced stamping accuracy caused by component wear or damage.
[0027] Working principle: When using this device, install this device on the workbench through the first connecting plate 33 and the second connecting plate 46, and then start the hydraulic cylinder 11. Under the action of the hydraulic cylinder 11, the telescopic end of the hydraulic cylinder 11 will drive the mounting plate 2 to move downward, which will drive the first limiting plate 21 on the left and the second limiting plate 22 on the right to move simultaneously, and will also drive the stamping head 5 at the bottom of the mounting plate 2 to punch downward. When the stamping head 5 punches to the maximum stroke, the second limiting plate 22 will squeeze the movable plate 42 inside the second limiting groove 41. At this time, the damper 43 and the spring 44 at the bottom of the movable plate 42 will contract under the downward extrusion force, thereby driving the movable plate 42 to contract towards the fixed plate 45. At the same time, the first limiting plate 21 will also move downward synchronously in the first limiting groove 31. Therefore, when the first limiting plate 21 moves downward to the bottom and touches the triggering end at the top of the travel switch 32, it means that the stamping head 5 has reached the maximum stroke, and the hydraulic cylinder 11 will stop working. This device accurately controls the stroke of the stamping head 5 through double limiting, ensuring that the stamping head 5 stops immediately when it reaches the maximum stroke, which not only improves the processing accuracy but also avoids damage to the workbench caused by over-travel, and can effectively improve the overall production efficiency. Moreover, when the stamping head 5 is damaged and needs to be replaced, by simply unscrewing the nut 53 and the fastening bolt 52, the damaged stamping head 5 can be easily removed and replaced with a new one. The entire replacement process is fast and convenient, which can effectively avoid the problem of reduced stamping accuracy caused by component wear or damage.

Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
