Technical Field

[0001] The utility model relates to the technical field of sheet metal processing, in particular to a stamping structure of a sheet metal mold. Background Technique

[0002] A stamping die is a special process equipment for processing workpieces in cold stamping. It is called a cold stamping die. The workpiece is stamped through the stamping die to generate deformation so that the workpiece reaches the predetermined shape. With the continuous development of society, the stamping die is also constantly improved. There are various types of such stamping dies in the current market, which can basically meet people's usage needs. For example, a stamping die is needed when processing arc-shaped sheet metal workpieces. However, the current stamping die for arc-shaped sheet metal workpieces is inconvenient to use. When the workpiece is processed, it is not easy to take out, and the stamping equipment lacks a structure for cleaning the stamping die. During processing, some scraps will fall into the stamping die. If the scraps are not cleaned, it will affect the workpiece and the die during the next stamping. Therefore, we propose a stamping structure of a sheet metal mold to solve the above problems. Content of the Utility Model

Detailed implementation manner

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0019] Such as Figure 1 , Figure 2 And Figure 3As shown in the figure, a stamping structure of a sheet metal mold proposed by an embodiment of the present utility model includes a bottom plate 1. Installation holes 13 are provided at the four corners of the top of the bottom plate 1, which makes it more convenient to install and fix the bottom plate 1. A lower template 2 is fixed to the top of the bottom plate 1, and a forming seat 3 is fixed to the top of the lower template 2. A top ejection assembly 4 is arranged on the forming seat 3. A support 5 is fixed to the top of the bottom plate 1, and a hydraulic cylinder 6 is fixed to the top of the support 5. The ejection end of the hydraulic cylinder 6 slidably penetrates through the support 5 and extends to its lower part and is fixed with an upper template 7. Two T-shaped rods 11 slidably penetrate through the top of the support 5. The bottom ends of the T-shaped rods 11 are fixedly connected to the upper template 7, which can play a guiding and supporting role for the upper template 7, so that it will be more stable during the up and down movement. A forming block 8 adapted to the forming seat 3 is fixed to the bottom of the upper template 7. Pressure plates 9 fixed to the bottom of the upper template 7 are arranged on both sides of the forming block 8. An air blowing assembly 10 for cleaning the inner wall of the forming seat 3 is arranged on the top of the bottom plate 1. When using this stamping die, the processing sheet can be placed on the forming seat 3 from one side for limiting. The hydraulic cylinder 6 is started to drive the upper template 7 to move down. After the upper template 7 moves down, it will drive the forming block 8 to move down to stamp and form the processing sheet. And when the upper template 7 moves down, it will drive the two pressure plates 9 to move down. After the pressure plates 9 move down, they will first squeeze the top ejection assembly 4 to prevent the top ejection assembly 4 from affecting the forming. After stamping is completed, when the upper template 7 is reset, it will drive the pressure plates 9 to reset. When the top ejection assembly 4 is released from the extrusion, the formed arc-shaped workpiece can be jacked up for the convenience of the staff to take. And after the upper template 7 moves up, it will drive the air blowing assembly 10 to move into the forming seat 3, and then the inside can be cleaned. When the upper template 7 moves down, it can also synchronously drive the air blowing assembly 10 away from the forming seat 3 to avoid affecting its forming process.

[0020] As Figure 4 shown, there is another way for the top ejection assembly 4 in the present utility model. It mainly includes a top material plate 14 slidably penetrating through the forming seat 3. Four limiting rods 15 are fixed to the top of the lower template 2. A support plate 16 is slidably connected between the four limiting rods 15. The bottom of the top material plate 14 is fixedly connected to the support plate 16. Two second springs 17 are fixed to the bottom of the support plate 16. The bottom ends of the second springs 17 are fixedly connected to the top of the lower template 2. When in use, under the action of the second springs 17, the support plate 16 can move up and down, and after the support plate 16 moves, it can drive the top material plate 14 to move up, so as to realize jacking up the processed arc-shaped workpiece.

[0021] As Figure 1 and Figure 3As shown, in some embodiments, the ejection assembly 4 includes two ejection plates 401. The bottoms of the two ejection plates 401 slide through the forming base 3 and extend below it, and a cross plate 402 is fixed. Circular rods 403 are fixed at the four corners of the top of the lower template 2. Moving plates 404 are slidably connected to the surfaces of the circular rods 403. One side wall of each moving plate 404 is fixedly connected to the cross plate 402. First springs 405 are fixed to the bottoms of the moving plates 404. Two rubber buffer blocks 12 are fixed to the top of the lower template 2, which can limit the maximum degree of extrusion of the first springs 405, thereby preventing excessive extrusion of the first springs 405. The bottom ends of the first springs 405 are fixedly connected to the top of the lower template 2. During use, the first springs 405 provided can be used to move the moving plates 404 up and down, and after the moving plates 404 move, they can drive the ejection plates 401 to move, so as to realize ejecting the processed arc-shaped workpiece.

[0022] As Figure 1 As shown, in some embodiments, the air blowing assembly 10 includes a guide rail 1001 fixed to the top of the bottom plate 1. A slide rod 1002 is slidably connected inside the chute of the guide rail 1001. An air blowing plate 1003 is fixed to the top of the slide rod 1002. An air inlet pipe 1004 is fixedly connected and communicated to the top of the air blowing plate 1003. A connecting rod 1005 is rotatably connected to one side wall of the upper template 7 through a pin shaft. The bottom end of the connecting rod 1005 is rotatably connected to the air blowing plate 1003 through a pin shaft. During use, an air conveying hose can be fixedly connected and communicated to the air inlet pipe 1004. After the upper template 7 moves up, with the cooperation of the connecting rod 1005, the air blowing plate 1003 can be moved to the forming base 3, and then air blowing and cleaning can be carried out on it. When the upper template 7 moves down, it can also drive the air blowing plate 1003 away from the forming base 3, so as to avoid affecting the stamping process of the workpiece.

[0023] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
