Description

Technical Field

[0001] The utility model discloses a punching chip-preventing structure, belonging to the field of metal shell punching equipment. Background Art

[0002] Metal can stamping is a metal processing process that applies force to the metal plate to subject it to deformation processes such as bending, stretching, compression or shearing, thereby stamping the metal plate into the desired shape. Metal shell stamping is usually operated using a punching machine, in which the metal sheet is placed in a mold and then force is applied by punching up or punching down for stamping. This process can be used to manufacture various metal shells, such as automotive parts, home appliance shells, mobile phone shells, etc. Metal shell stamping has the advantages of high efficiency, precision and repeatability, making it one of the common process methods for large-scale production of metal parts.

[0003] The metal shell stamping anti-chipping structure is a device used for metal shell stamping processing. The metal shell blank plate is placed directly above the mold, and the stamping mold is manually pressed down to fit with the mold below, so that the blank plate can be stamped from top to bottom. After stamping, manual demolding is required, which reduces the continuity of the metal shell stamping process and also reduces the efficiency of the metal shell stamping process.

[0004] In summary, the utility model provides a stamping anti-chip jumping structure to solve the above-mentioned problem. Utility Model Content

[0007] Furthermore, the front and rear sides of the top of the punching table and directly above the automatic demoulding module are fixedly connected with limit baffles, and the side of the punching table away from the blanking component is sloped.

[0008] Furthermore, the blanking assembly includes a fixed plate, which is fixedly connected to one side of the top of the stamping table, and two electric push rods are fixedly connected to one side of the fixed plate. A push plate is fixedly connected between the output ends of the two electric push rods and located on the top of the stamping table.

[0010] Furthermore, the stamping die set includes four hydraulic rods, which are all fixedly connected to the bottom of the mounting plate and located directly above the automatic demoulding die set, and a stamping template is fixedly connected between the output ends of the four hydraulic rods.

[0011] Furthermore, the automatic demolding module includes a die base, which is embedded in the top of the stamping table and directly below the stamping die group, the bottom of the die base penetrates the stamping table and extends to the top of the bottom plate, a die groove is provided at the top of the die base and directly below the stamping die group, two mounting grooves are provided inside the die base and directly below the die groove, a demolding plate is embedded in the top of the die groove, three demolding rods are fixedly connected on both sides of the bottom of the demolding plate and directly above the two mounting grooves, the bottom end of each of the three demolding rods penetrates the die groove and extends to the inside of the mounting groove, a movable plate is fixedly connected between the bottom ends of each three demolding rods and inside the mounting groove, and a plurality of compression springs are evenly fixedly connected from front to back between the bottom of the movable plate and the bottom of the inner wall of the mounting groove.

[0014] Beneficial effects of the utility model:

[0015] The metal shell blank plate below the stamping die is started to be stamped from top to bottom. After stamping, the stamping die is closed, and the stripping plate is moved upward by the rebound force of the compression spring below, so that the metal shell inside the die groove can be ejected for automatic demoulding. When the stamping die plate is moved upward after the stamping process is completed, the metal shell below can be automatically demoulded, which effectively improves the continuity of the metal shell stamping process, thereby improving the metal shell stamping process efficiency. In addition, this design prevents metal debris from splashing during the processing.

[0018] The damping ring can be used to buffer and reduce vibration of the movable plate, thereby reducing the noise generated by the movable plate colliding with the die base after the compressed spring rebounds and resets, effectively improving the working environment quality of the metal shell stamping anti-chip jumping structure.

The two electric push rods 62 are both connected to an external power supply and are provided with the same power control switch. The bottom of the push plate 63 is in contact with the top of the stamping table 5. The width of the push plate 63 is less than the spacing between the two limit baffles 9. The two limit baffles 9 can center the metal shell stamping blank plate, so that the metal shell stamping blank plate can be located directly below the stamping die 7.

[0030] See also Figure 3 and Figure 5 The stamping die set 7 includes four hydraulic rods 71, which are fixedly connected to the bottom of the mounting plate 3 and located directly above the automatic demolding die set 8. A stamping template 72 is fixedly connected between the output ends of the four hydraulic rods 71. The four hydraulic rods 71 ​​are all provided with the same control switch. The width of the stamping template 72 is equal to the distance between the two limit baffles 9.

[0031] See also Figure 3-6The automatic demoulding module 8 includes a die base 81, which is embedded in the top of the punching table 5 and is located directly below the punching die set 7. The bottom of the die base 81 penetrates the punching table 5 and extends to the top of the bottom plate 1. A die groove 82 is provided at the top of the die base 81 and is located directly below the punching die set 7. Two mounting grooves 83 are provided inside the die base 81 and are located directly below the die groove 82. A stripping plate 84 is embedded in the top of the die groove 82. Three stripping rods 85 are fixedly connected on both sides of the bottom of the stripping plate 84 and are located directly above the two mounting grooves 83. The bottom ends of each of the three stripping rods 85 penetrate the die groove 82 and extend to the inside of the mounting groove 83. The bottom ends of each of the three stripping rods 85 are fixedly connected between the bottom ends of the three stripping rods 85 and are located inside the mounting groove 83. There is a movable plate 86, and a plurality of compression springs 87 are evenly fixedly connected between the bottom of the movable plate 86 and the bottom of the inner wall of the mounting groove 83 from front to back. The movable plate 86 has a limiting effect on the demoulding rod 85, and the movable plate 86 is slidably connected to the mounting groove 83. The stamping template 72 and the demoulding template 84 have the same shape and volume. The top of the demoulding template 84 and the top of the die base 81 are located at the same horizontal height. The top of the inner wall of the mounting groove 83 and the rod surface of each demoulding rod 85 are sleeved with a damping ring 88, the demoulding rod 85 is in contact with the die base 81, and the demoulding rod 85 is in contact with the damping ring 88. The top of the damping ring 88 is fixedly connected to the top of the inner wall of the mounting groove 83, and the movable plate 86 can be buffered and vibration-reduced by the damping ring 88.

[0032] Specific implementation method: by placing the metal shell stamping blank plate on the top of the stamping table 5 and on one side of the push plate 63, starting the two electric push rods 62, so that the push plate 63 can be pushed from right to left, and the metal shell stamping blank plate is pushed from right to left by the push plate 63, and the metal shell stamping blank plate is pushed to the top of the automatic demoulding module 8, and the four hydraulic rods 71 ​​inside the stamping module 7 are started to drive the stamping template 72 to move downward at the same time, and then the metal shell blank plate below can be stamped from top to bottom, and the demoulding template 84 is pushed downward at the same time, and multiple demoulding rods 85 are driven to move downward at the same time. The metal shell blank plate is stamped and formed through the die groove 82 below, and the four hydraulic rods 71 ​​inside the stamping die set 7 are closed, so that the stamping die plate 72 can be driven to move upward. Since the stripping die plate 84 is no longer under pressure and will not continue to squeeze the compression spring 87, the rebound force of the compression spring 87 can be used to push the movable plate 86 to move and reset, thereby driving the stripping rod 85 to move upward and reset, and then driving the stripping die plate 84 to move upward. The inside of the die groove 82 moves upward to reset. Since the top horizontal height of the demoulding plate 84 after reset is the same as the top horizontal height of the die base 81, the metal shell inside the die groove 82 can be ejected and automatically demoulded. When the stamping plate 72 is moved upward after the stamping process is completed, the metal shell below can be automatically demoulded, which effectively improves the continuity of the metal shell stamping process, thereby improving the metal shell stamping process efficiency. At the same time, the electric push rod 62 inside the blanking component 6 can be started to push the push plate 63 to the left, so that the formed metal shell is pushed from the top of the demoulding plate 84 to one side of the top of the die base 81 , and then one side of the top of the right die base 81 is pushed to the slope at the top of the stamping table 5, and the material is slid and unloaded through the slope, which effectively improves the efficiency of the metal shell stamping process. The movable plate 86 can be buffered and vibration-reduced through the damping ring 88, so that the noise generated by the collision between the movable plate 86 and the die base 81 after the compression spring 87 rebounds and resets can be reduced, which effectively improves the working environment quality of the metal shell stamping anti-chip jumping structure. The demolding rod 85 can be limited by the movable plate 86, so that the demolding plate 84 can be limited, ensuring that the height of the demolding plate 84 after resetting can be consistent with the height of the top of the die base 81.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
