Detailed implementation manner

[0021] In the following, embodiments of the punching device for the pin hole of the broken bridge aluminum window frame of the present utility model will be described with reference to the accompanying drawings.

[0022] Figures 1-4 The punching device for the pin hole of the broken bridge aluminum window frame showing an embodiment of the present utility model includes a punching table 1. On both sides of the bottom of the inner cavity of the punching table 1, bases 2 are fixedly connected. On the top of the bases 2, a punching assembly 3 is provided. The punching assembly 3 includes guide rods 31 fixedly connected to the four corners of the top of the bases 2. At the tops of the four guide rods 31, a fixed plate 32 is fixedly connected. On both sides of the top of the punching table 1, hydraulic cylinders 33 are fixedly installed. The output ends of the hydraulic cylinders 33 penetrate to the bottom of the fixed plate 32 and are fixedly connected to the lifting plate 34 through flanges. A spring 35 is sleeved on the surface of the guide rod 31. The top and bottom ends of the spring 35 are respectively welded to the lifting plate 34 and the base 2. Through the setting of the spring 35, it plays an elastic pushing role on the lifting plate 34, so that when the hydraulic cylinder 33 drives the lifting plate 34 to reset upward, the spring 35 can squeeze the lifting plate 34 upward to assist the lifting plate 34 to actively reset. At the same time, it plays an elastic supporting role for the lifting plate 34 when not in use. There is a liftable lifting plate 34 between the base 2 and the fixed plate 32. A stamping die 4 is fixedly connected to the top of the base 2. The bottom of the lifting plate 34 is fixedly connected with a fixed arm 5 through bolts. The front side of the bottom of the fixed arm 5 is fixedly connected with a stamping head 6. A stamping hole 7 adapted to the stamping head 6 is opened on the front side of the top of the stamping die 4. A material discharging groove 9 is opened on the front side of the punching table 1. The inner cavity of the material discharging groove 9 is communicated with the stamping hole 7. An alignment component 8 is provided on the top of the stamping die 4. The alignment component 8 includes an alignment baffle 81 slidably connected to the surface of the stamping die 4. At the top of the inner cavity of the alignment baffle 81, a threaded sleeve 82 is fixedly connected. A rectangular sliding groove 83 adapted to the threaded sleeve 82 is opened on the top of the stamping die 4. The front side of the inner cavity of the rectangular sliding groove 83 is rotatably connected with a threaded pin 84 through a bearing. The rear end of the threaded pin 84 penetrates to the rear side of the stamping die 4. The threaded sleeve 82 is threadedly connected to the surface of the threaded pin 84. A scale mark 85 is provided on the right side of the top of the stamping die 4. Through the cooperation of the threaded sleeve 82 and the threaded pin 84, it plays a threaded pushing role on the alignment baffle 81, so that the position of the alignment baffle 81 can be adjusted, thereby facilitating the user to calibrate the punching position and improving the punching efficiency of the pin hole.

[0023] Working principle: When the utility model is in use, the user first rotates the threaded pin 84. During the rotation of the threaded pin 84, the threaded sleeve 82 is pushed forward through the threads on its surface, so that the alignment baffle 81 slides driven by the threaded sleeve 82. At the same time, the user adjusts the position of the alignment baffle 81 with reference to the scale mark 85, and then the punching position of the broken bridge aluminum profile can be adjusted. After the adjustment is completed, the user places the broken bridge aluminum profile on the top of the stamping die 4, and makes the rear side of the broken bridge aluminum profile contact the front side of the alignment baffle 81, so as to calibrate the punching position. Subsequently, the hydraulic cylinder 33 is started and drives the lifting plate 34 to slide downward on the surface of the guide rod 31, so that the fixed arm 5 and the punching head 6 are pressed downward. After the bottom end of the punching head 6 completely penetrates the broken bridge aluminum profile and enters the inner cavity of the punching hole 7, the punching is completed. Subsequently, the hydraulic cylinder 33 drives the lifting plate 34 to reset upward. At this time, the scraps generated by punching enter the inner cavity of the material discharge groove 9 from the inner cavity of the punching hole 7, and exit forward under the action of the inclined surface at the bottom of the inner cavity of the material discharge groove 9.

[0024] To sum up: For the stamping device for the pin holes of the broken bridge aluminum window frame, through the setting of the alignment component 8, the punching position is preset. Subsequently, the broken bridge aluminum profile is placed on the top of the stamping die 4, and with the coordinated use of the punching component 3, the fixed arm 5 and the punching head 6, the punching can be quickly completed, thus achieving the purpose of facilitating the alignment of the punching position, fast stamping and accurate position.
