They can be flexibly adjusted and optimized according to different usage scenarios and needs, providing reliable support and guarantee for industrial production and engineering construction. They are an indispensable and important part of modern industry.

[0003] In order to facilitate the connection between various metal brackets, it is usually necessary to punch holes on the workpiece. When using the existing punching machine, workers usually use corresponding fixtures to fix the workpiece first, and then the machine processes it according to the set processing data. However, in complex structural parts, blind holes need to be processed at the corresponding positions on both sides of the bracket to meet the connection requirements. Therefore, after drilling one side, the machine needs to be stopped and the worker needs to turn the workpiece over and reposition it on the other side. In order to ensure the accuracy of the drilling, this process will take a lot of time and the work efficiency is low. In view of this, the present application proposes a metal bracket punching device. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figure 1 and Figure 4 As shown, in the present embodiment, a metal bracket punching device comprises a base 1, a guide rail 2 is fixedly mounted on the upper end of the base 1, a slider 3 is slidably mounted on the guide rail 2, a movable arm 4 is mounted on the upper end of the slider 3, a body 5 for punching is mounted on the movable arm 4, a storage groove 6 is provided on the upper surface of the base 1, a double-headed screw 7 is arranged in the storage groove 6, one end of the double-headed screw 7 is rotatably connected to the inner wall of the storage groove 6, the other end of the double-headed screw 7 is connected through the base 1, and the end of the double-headed screw 7 extending outside the base 1 is connected to a motor through a coupling, and further, when the motor is started, the output shaft of the motor will drive the double-headed screw 7 to rotate synchronously.

[0022] Two nuts 8 are symmetrically arranged on the double-headed screw 7, and assembly blocks 9 are respectively sleeved on the two nuts 8. The two assembly blocks 9 are both arranged in the storage groove 6, and the side walls of the two assembly blocks 9 are in contact with the inner wall of the storage groove 6. It should be noted that when the double-headed screw 7 rotates, the nut 8 will drive the side wall of the assembly block 9 to resist the inner wall of the storage groove 6, thereby limiting the rotation of the nut 8, and finally causing the nut 8 to move along the direction in which the double-headed screw 7 is set.

[0023] The upper ends of the two assembly blocks 9 are respectively fixedly connected with support plates 10, wherein the top of one support plate 10 is connected to a fixed plate 12 via a movable shaft 11, and the other support plate 10 is connected to another fixed plate 12 via an adjusting device, and clamping devices are provided on both fixed plates 12.

[0024] The adjusting device includes a limit slot 19 and a movable block 20. A through hole is vertically opened at the corresponding position of the movable block 20 and the support plate 10. A limit rod 21 is passed through the through hole. The limit rod 21 extends to one end outside the support plate 10 and is fixedly connected to a pull plate 22. A connecting rod 23 is fixedly connected to the side wall of the movable block 20. The connecting rod 23 extends to one end outside the support plate 10 and is fixedly connected to a handle 24. Furthermore, the movable block 20 can be fixed in the limit slot 19 by setting the limit rod 21 to avoid movement of the metal bracket during the punching process, thereby ensuring the accuracy of the punching.

[0025] The limiting groove 19 is designed as a square groove, and the side wall of the movable block 20 contacts the inner wall of the limiting groove 19. The end of the movable block 20 extending outside the limiting groove 19 is fixedly connected to the side wall of the corresponding fixed plate 12. Furthermore, by judging whether the movable block 20 can be moved into the square limiting groove 19, the metal bracket can be rotated 180° quickly and accurately.

[0026] The clamping device includes a support plate 13 and an extension plate 14. A threaded sleeve 15 is passed through the extension plate 14, and the threaded sleeve 15 and the extension plate 14 are fixedly connected. A threaded rod 16 is passed through the threaded sleeve 15, a knob 17 is fixedly connected to the top of the threaded rod 16, and a pressure plate 18 is rotatably connected to the bottom of the threaded rod 16.

[0027] The support plate 13 is fixed at the bottom of the fixed plate 12, the extension plate 14 is fixed at the top of the fixed plate 12, and the side walls of the pressure plate 18 are in contact with the side walls of the fixed plate 12. It should be noted that when the threaded rod 16 rotates, the side walls of the pressure plate 18 are against the fixed plate 12, which can prevent the pressure plate 18 from rotating with the threaded rod 16, ensure that the corresponding side walls of the pressure plate 18 and the support plate 13 remain parallel, increase the contact area with the metal bracket, and ensure stability during clamping.

[0028] The utility model provides a metal bracket punching device, and the specific working principle is as follows: the base 1 is installed in the working area, and the motor is started. The output shaft of the motor will drive the double-headed screw 7 to rotate synchronously. Under the limit of the assembly block 9, the nut 8 cannot rotate, so that the nuts 8 on both sides move toward each other along the direction set by the double-headed screw 7, driving the upper support plate 10 to move synchronously. According to the length between the metals to be processed, the spacing between the support plates 10 on both sides is adjusted, so that the two ends of the metal bracket are placed on the support plates 13 on both sides, and the knobs 17 on both sides are turned respectively to drive the threaded rod 16 to rotate. Under the limit of the threaded sleeve 15, the threaded rod 16 will move with the pressing plate 18 below, and finally abut against the upper surface of the metal bracket, and cooperate with the support plate 13 to complete the fixation of the metal bracket. The position of the movable arm 4 can be adjusted by moving the slider 3 on the guide rail 2. When it moves to the position where the holes are required to be punched, the movable arm 4 drives the machine body 5 to move to complete the punching of the metal bracket.

[0029] When the other side of the metal bracket needs to be processed, first move the pull plate 22 upward to drive the limit rod 21 to move out of the support plate 10, so that pushing the handle 24 can drive the movable block 20 to move out of the limit groove 19. At this time, the movable shaft 11 on the other side also slides with the corresponding support plate 10. Turning the handle 24 can drive the fixed plates 12 on both sides to flip over. By comparing the angle between the movable block 20 and the square limit groove 19, it can accurately rotate 180° to quickly complete the flipping of the metal bracket, saving the time of re-clamping and positioning, and improving work efficiency.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
