DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0020] The traditional punching die punching structure has a single function when in use. It can only realize a single unloading and demoulding function, and cannot fix the workpiece to be punched. As a result, the workpiece is easily deflected during the punching operation, which in turn affects the production qualification rate of the workpiece, thus bringing inconvenience to the staff.

[0021] In view of this, the utility model provides a rod structure of a stamping die, which can automatically fix the workpiece when stamping through the cooperation of the upper die, the first step punch, the second step punch, the punching device and the fixing device, thereby avoiding the phenomenon of force deviation of the workpiece during stamping, greatly improving the stamping quality of the workpiece, and automatically demolding the workpiece after the stamping is completed, thereby facilitating the use of the staff.

[0022] Embodiment 1: Figure 1 , 2, 3 and 4 show that a punching rod structure of a stamping die comprises an upper die 1, a first step punch 6 is installed at the bottom of the upper die 1, a second step punch 7 is installed at the bottom of the first step punch 6, and power equipment 5 is installed on both sides of the top of the upper die 1. The punching rod structure of the stamping die also includes: a punching device 2, which is arranged above the second step punch 7; a fixing device 3, which is installed at the four corners of the upper die 1; and an adjusting device 4, which is arranged at the four corners of the upper die 1; wherein the punching device 2 can discharge the material inside the second step punch 7, the fixing device 3 can fix and limit the workpiece to be stamped, and the adjusting device 4 can change the stamping distance of the first step punch 6;

[0023] In the specific implementation process, it is worth pointing out that the present case should be equipped with a lower die corresponding to the upper die 1, the first step punch 6 and the second step punch 7, so as to complete the stamping work. It can be understood that the first step punch 6 and the second step punch 7 provided in the present embodiment are only a feasible implementation method for processing external workpieces. The selection of the specific structure can be reasonably designed according to the actual situation. The punching device 2 can demould the stamped workpiece inside the second step punch 7, the fixing device 3 can press and fix the workpiece to be processed, and after the stamping is completed, the workpiece can be taken away from the outer wall of the first step punch 6, and the adjusting device 4 can adjust the stamping depth of the first step punch 6;

[0024] Specifically, when using the hitting rod structure of the stamping die, the staff first uses the adjustment device 4 to change the stamping depth of the first step punch 6, and then the stamping work can be carried out. When stamping, the fixing device 3 can be used to press and fix. When the stamping is completed, the fixing device 3 and the punching device 2 can demold the workpiece.

[0025] Embodiment 2: By Figure 1 , 2 As can be seen from Figures 4, the punching device 2 includes: a punching rod 201, which is installed inside the upper mold 1 and is movably connected to the inner wall of the first step punch 6; a discharge plate 202, which is fixedly connected to the bottom of the punching rod 201 by bolts; a boss 203, which is installed on the top of the upper mold 1 and is movably connected to the outer wall of the punching rod 201; two first springs 204 are provided, both of which are installed on the top of the boss 203 and are fixedly connected to the upper part of the punching rod 201; wherein, when the first spring 204 is stretched, it will drive the discharge plate 202 to move downward through the punching rod 201;

[0026] In the specific implementation process, it is worth pointing out that the boss 203 can limit the position of the hitting rod 201. When the first spring 204 is stretched, the first spring 204 will give the hitting rod 201 a downward force, so that the hitting rod 201 can bring the workpiece away from the inner wall of the second step punch 7 through the stripper plate 202.

[0027] Specifically, based on the above-mentioned embodiment 1, when the stamping is completed, the elastic force of the first spring 204 can drive the hitting rod 201 to move downward, and the hitting rod 201 drives the unloading plate 202 to move downward, and then the workpiece can be pushed out from the inner wall of the second step punch 7 through the unloading plate 202, thereby realizing the unloading work.

[0028] Embodiment 3: By Figure 1 , 2 As can be seen from Figure 3, the fixing device 3 includes: a pressing plate 301, which is arranged below the upper mold 1; four vertical rods 302, which are respectively installed at the top four corners of the pressing plate 301 and are all movably connected to the inner wall of the upper mold 1; four top plates 303, which are respectively installed at the tops of the four vertical rods 302; a plurality of second springs 304, which are respectively installed at the bottoms of the four top plates 303 and are all fixedly connected to the top of the upper mold 1; wherein, when the second spring 304 is stretched, it will drive the vertical rods 302 through the top plates 303 to drive the pressing plate 301 to move downward;

[0029] In the specific implementation process, it is worth pointing out that when the second spring 304 is stretched, the second spring 304 will exert a downward force on the pressing plate 301 through the vertical rod 302 and other components, thereby limiting and fixing the workpiece to be stamped;

[0030] Furthermore, a rubber pad 8 is fixedly connected to the bottom of the pressing plate 301;

[0031] In the specific implementation process, it is worth pointing out that the rubber pad 8 can improve the pressing stability between the pressing plate 301 and the workpiece;

[0032] Specifically, on the basis of the above-mentioned embodiment 1, when the upper mold 1 moves downward, the upper mold 1 can drive the pressure plate 301 and other components to move downward. When the pressure plate 301 contacts the top of the workpiece, the vertical rod 302 can move upward along the upper mold 1 and stretch the second spring 304 at the same time. At this time, the workpiece can be pressed and limited by the pressure plate 301 through the elastic force of the second spring 304. After the stamping is completed, when the upper mold 1 moves upward, due to the elastic force of the second spring 304, the vertical rod 302 and the pressure plate 301 and other components can be driven to move downward, and the workpiece can be pushed away from the outer wall of the first step punch 6.

[0033] Embodiment 4: By Figure 1 , 2As can be seen from Figure 3, the adjusting device 4 includes: four threaded rods 401, which are respectively rotatably connected to the inner walls of the four top plates 303 through bearings; four sliders 402, which are respectively threadedly connected to the outer walls of the four threaded rods 401 and are respectively movably connected to the inner walls of the four vertical rods 302; multiple clamping plates 403 are respectively installed on the outer walls of the four sliders 402 and are respectively slidably clamped with the inner walls of the four vertical rods 302; wherein, twisting the threaded rod 401 can drive the clamping plate 403 to move along the inner wall of the vertical rod 302 through the slider 402;

[0034] In the specific implementation process, it is worth pointing out that the punching depth of the first step punch 6 can be adjusted by the cooperation between the clamping plate 403 and the upper die 1, thereby meeting a variety of different usage requirements;

[0035] Specifically, based on the above-mentioned embodiment 1, when it is necessary to change the stamping depth of the first step punch 6, the staff twists the threaded rod 401, and the threaded rod 401 can drive the slider 402 to move along the inner wall of the vertical rod 302, and the slider 402 drives the clamping plate 403 to move. At this time, as the position of the clamping plate 403 changes, the stamping depth of the first step punch 6 can be changed.
