DETAILED DESCRIPTION

[0039] In order to make the above objectives, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0040] In the following description, a large number of specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the concept of the present application, therefore the present application is not limited to the specific embodiments disclosed below.

[0041] Second, the "one embodiment" or "an embodiment" referred to herein means a specific feature, structure, characteristic, or combination of features and / or characteristics described herein that can be included in at least one implementation of the present application. The various appearances of "in one embodiment" or "an embodiment" in the specification do not all refer to the same embodiment, although they can.

[0042] Embodiment 1, refer to Figures 1-6 , the first embodiment of the application, the embodiment provides an aluminum plate stamping device for bottle cap processing, the aluminum plate stamping device for bottle cap processing includes stamping assembly 1, stripping polishing assembly 2, ejection fixing assembly 3, feeding assembly 4, flattening assembly 5, fan 6 and discharge frame 7.

[0043] Specifically, the stamping assembly 1, including the base 11, the base 11 is installed with the stamping machine 12, the stamping machine 12 is a crank stamping machine, which is prior art, the working principle and so on in this part are prior art, the person skilled in the art can clearly know, here is not repeated, can realize the up-down reciprocating movement of the moving seat 14, and then realize the reciprocating movement of the punch 15, stamp the aluminum plate conveyed, form the bottle cap in the mold cavity 17 with the help of the lower die 13, which is prior art, the working principle and so on in this part are prior art, the person skilled in the art can clearly know, here is not repeated.

[0044] The base 11 is fixed with the lower die 13, the driving end of the stamping machine 12 is fixed with the moving seat 14, the inner wall of the moving seat 14 is fixed with the punch 15, the surface of the punch 15 is provided with a guide groove 16, the top of the lower die 13 is provided with a mold cavity 17, and the punch 15 is matched with the punch 15, the moving seat 14 is slidably provided with a positioning rod 18, and the lower end of the positioning rod 18 is fixed to the top of the lower die 13.

[0045] The positioning rod 18 penetrates through the moving seat 14 and is slidably connected with the moving seat 14, the number of the positioning rod 18 is four, the moving seat 14 is guided and positioned by the positioning rod 18, so that the punch 15 can be accurately inserted into the mold cavity 17 on the lower die 13 when the punch 15 moves down, through the setting of the guide groove 16, when the pressure plate 212 contacts with the lower die 13 during the up-down movement of the punch 15, the driving part 24 can be acted on, and under the cooperation of the transmission part 23, whether the polishing wheel 22 rotates or not is realized.

[0046] Specifically, the demolding and polishing assembly 2 is installed on the moving seat 14 and the punch 15 and arranged on the lower die 13, and includes a pressing piece 21 installed on the moving seat 14 and the lower die 13. Through the arrangement of the pressing piece 21, the corresponding part of the aluminum plate to be punched can be pressed and held during the downward movement of the pressing piece 21, the moving seat 14 and the punch 15, so as to reduce the movement of the aluminum plate during the punching process. The pressing and holding of the aluminum plate can avoid the action between the aluminum plate and the punch 15, so that the punch 15 moves upward to drive the punched part of the aluminum plate to move upward. After the punch 15 moves away from the lower die 13 and the aluminum plate gradually moves upward, the pressing plate 212 on the pressing piece 21 gradually moves upward to separate from the aluminum plate.

[0047] The polishing wheel 22 is rotatably arranged on the pressing piece 21. Through the arrangement of the polishing wheel 22, firstly, the corresponding part of the aluminum plate to be punched can be pressed and held after the polishing wheel 22 contacts the aluminum plate during the downward movement of the pressing piece 21. Then, after the punch 15 completes the punching process and moves upward, the polishing wheel 22 can limit the bottle cap formed in the mold cavity 17, so as to avoid the bottle cap adhering to the surface of the punch 15, which causes the material to be unable to be taken out and affects the subsequent punching and forming of the bottle cap.

[0048] Finally, during the upward movement of the punch 15, the polishing wheel 22 can be rotated under the driving of the driving member 24 and the transmission member 23, so as to polish the fracture of the bottle cap in contact with the polishing wheel 22, thereby removing the burrs and avoiding the damage to the human body when the bottle cap is taken by the operator. At the same time, the polishing can play a certain auxiliary role in polishing and separating the formed bottle cap from the aluminum plate.

[0049] The driving member 24 is installed on the surface of the punch 15 and rotates on the surface of the polishing wheel 22. The transmission member 23 is installed between the polishing wheel 22 and the driving member 24. Through the arrangement of the transmission member 23, after the pressing piece 21 presses and holds the aluminum plate, the polishing wheel 22 will not rotate under the action of the driving member 24 during the downward movement of the punch 15. After the punching is completed, the polishing wheel 22 can rotate under the action of the driving member 24 during the upward movement of the punch 15, so as to polish the fracture of the bottle cap.

[0050] Specifically, the ejection fixing assembly 3 is fixed to the lower die 13 and includes a top spring 31 installed on the lower die 13. Through the arrangement of the top spring 31, the bottle cap formed in the mold cavity 17 after punching can be provided with a driving force, so as to facilitate the demolding of the bottle cap after the punch 15 and the pressing plate 212 move upward after the punching is completed, so that the bottle cap can be smoothly discharged without affecting the subsequent punching process.

[0051] The bottom of the lower die 13 is fixed with a suction element 32, and the suction element 32 is communicated with the top elastic element 31. Through the setting of the suction element 32, when the aluminum plate is subjected to stamping to form the bottle cap in the die cavity 17, and the top elastic element 31 is lowered, the suction element 32 generates suction force under the cooperation of the rubber ring 33, so as to adsorb and fix the bottle cap. The fixing function firstly reduces the upward movement of the bottle cap from the punch 15, and then fixes the bottle cap, so as to avoid the rotation of the bottle cap with the rotation of the polishing wheel 22, and make the polishing wheel 22 better polish the bottle cap.

[0052] The top elastic element 31 is respectively fixed with the rubber ring 33 and the elastic sheet 34. The top ring 35 is fixed at the upper end of the elastic sheet 34 and slides in the rubber ring 33. Through the setting of the elastic sheet 34, the top ring 35 is pressed down to be flush with the rubber ring 33 in the process of stamping the bottle cap. At this time, the elastic sheet 34 is deformed. In the subsequent pressing process, the elastic sheet 34 and the top ring 35 move downward together with the rubber ring 33. When the bottle cap moves upward from the die cavity 17 and separates from the pressing plate 212 after the subsequent stamping is completed, the bottle cap is bounced up by the upward force under the instantaneous elastic force of the elastic sheet 34, so as to be conveniently discharged into the discharge frame 7 under the action of the wind force.

[0053] Specifically, the feeding assembly 4 is installed on one side of the lower die 13 and cooperates with the moving seat 14. The feeding assembly 4 can intermittently feed the aluminum plate without affecting the normal stamping forming of the aluminum plate. The stamping machine 12 does not need to stop for feeding, has strong continuity, and improves the efficiency of processing and production.

[0054] Specifically, the flattening assembly 5 is installed on one side of the moving seat 14. Through the setting of the flattening assembly 5, a pulling force equivalent to one side can be provided for the aluminum plate during the downward movement of the punch 15 and the moving seat 14, and when the aluminum plate is not pressed by the downward pressing element 21, so that the stamping part of the aluminum plate is ensured to be flat. Then, a good condition is provided when the aluminum plate is pressed by the downward pressing element 21, so as to improve the quality of subsequent stamping.

[0055] Specifically, the fan 6 is fixed on the base 11, and the discharge frame 7 is fixed on the base 11. Through the operation of the fan 6, the demolded bottle cap can be blown to guide the bottle cap into the discharge frame 7 for discharge and collection.

[0058] Through the arrangement of the spring 213, when the pressing plate 212 is not in contact with the lower die 13, the pressing plate 212 is indirectly connected between the moving seat 14, so that when the moving seat 14 moves up and down, the pressing plate 212 can move together with the moving seat 14 under the action of the spring 213, after the pressing plate 212 is in contact with the lower die 13, the spring 213 is compressed with the downward movement of the moving seat 14, and the elastic force generated by the spring 213 acts on the pressing plate 212 to hold the aluminum plate, at the same time, the continuous downward movement of the moving seat 14 and the punch 15 is not affected, the aluminum plate is punched, and the subsequent upward movement of the punch 15 and the moving seat 14, when the spring 213 is not restored, can act on the pressing plate 212 to prevent the pressing plate 212 from moving upward, and then act on the polishing wheel 22, so that the polishing wheel 22 is in contact with the formed bottle cap to ensure the time and quality of polishing the bottle cap by the polishing wheel 22.

[0059] The driving piece 24 comprises a sleeve 241 sleeved on the surface of the punch 15, and the lower end of the sleeve 241 is rotationally connected to the polishing wheel 22, the inner wall of the sleeve 241 is embedded with a plurality of rolling balls 242, and the rolling balls 242 are slidingly arranged in the guide groove 16, the polishing wheel 22 is rotationally connected with the pressing plate 212 through a bearing, the sleeve 241 is rotationally connected with the polishing wheel 22 through a bearing, the sleeve 241 is slidingly sleeved on the surface of the punch 15, and the rolling balls 242 are rotationally arranged on the sleeve 241, during the process that the pressing plate 212 is in contact with the lower die 13 and no longer moves, the upward and downward movement of the punch 15 makes the rolling balls 242 move in the guide groove 16 thereon, so as to make the sleeve 241 rotate reversely or positively, so as to rotate the sleeve 241 when the punch 15 moves up and down.

[0060] The transmission piece 23 comprises a ratchet wheel 231 fixed to the lower end surface of the sleeve 241, a short rod 232 is fixed to the inner wall of the polishing wheel 22, a clamping block 233 is rotationally arranged on the short rod 232, and the clamping block 233 is matched with the ratchet wheel 231, the clamping block 233 is sleeved on the surface of the short rod 232, a torsional spring 234 is sleeved on the surface of the short rod 232, and the two ends of the torsional spring 234 are fixed to the surface of the clamping block 233 and the short rod 232, respectively.

[0061] The setting of the torsion spring 234 provides an elastic force to the clamping block 233, so that the clamping block 233 can be reset after rotation. The setting of the clamping block 233 and the cooperation of the torsion spring 234 enable the punch 15 to move downward, and the ratchet wheel 231 to rotate under the action of the driving piece 24, without driving the polishing wheel 22 to rotate. When the punch 15 moves upward and the ratchet wheel 231 rotates under the action of the driving piece 24, the polishing wheel 22 can rotate, thereby polishing the bottle cap to be subsequently ejected and demolded.

[0082] Embodiment 5, refer to Figures 3-15 This is the fifth embodiment of the application, which is based on the previous four embodiments.

[0083] Specifically, the flattening assembly 5 comprises an unfolding piece 51 mounted on one side of the moving seat 14. Through the unfolding piece 51, a pulling force can be provided to the aluminum plate during the downward movement of the punch 15 and the moving seat 14, and when the pressing piece 21 does not press the aluminum plate, so that the stamping part of the aluminum plate is ensured to be flat. The unfolding piece 51 is fixed with a fixed plate 52, and the fixed plate 52 is fixed with a fixed block 53. The fixed block 53 is provided with a clamping groove 54 on one side. The moving seat 14 is fixed with a fixing piece 55 on one side, which is matched with the clamping groove 54. The positioning rod 18 is fixed with a connecting plate 56 at the upper end. The connecting plate 56 is fixed with an unlocking plate 57 at the bottom, which is matched with the fixing piece 55.

[0084] Through the setting of the clamping groove 54, after the unfolding piece 51 is rotated by a certain angle and is positioned under the action of the fixing piece 55 after the downward stamping of the punch 15 and the moving seat 14 is completed, the unfolding piece 51 will not act on the aluminum plate during the subsequent resetting of the punch 15 and the moving seat 14, and only the downward stamping will play a flattening role. Through the setting of the unlocking plate 57, the fixing piece 55 can be acted on to release the fixing of the unfolding piece 51 after the upward movement, so as to reset the unfolding piece 51 for the next operation.

[0085] The unfolding piece 51 comprises a horizontal rod 511 fixed on the moving seat 14. The horizontal rod 511 is rotatably provided with a movable plate 512 on the surface. The movable plate 512 is fixed with a rubber wheel 513 at the lower end. The horizontal rod 511 is sleeved with a torsion spring 514 at both ends of the surface, and the both ends are respectively fixed on the surface of the movable plate 512 and the horizontal rod 511.

[0086] Through the setting of the torsion spring 514, when the rubber wheel 513 contacts the aluminum plate and moves downward with the moving seat 14 and the punch 15, the torsion spring 514 provides a force to the movable plate 512 to rotate the rubber wheel 513, so that the aluminum plate is pressed and moved at the same time. By means of the friction force, the aluminum plate is pushed to be flattened. In this process, the torsion spring 514 is deformed, and provides a force for the resetting of the movable plate 512, the rubber wheel 513, the connecting plate 56 and the fixed block 53 when the unlocking plate 57 releases the fixing of the fixed block 53 by the fixing piece 55.

[0087] The fixing piece 55 comprises a fixed rod 551 fixed on one side of the moving seat 14. The fixed rod 551 is fixed with a short block 552 at one end. The short block 552 is slidably provided with a clamping plate 553, which is matched with the clamping groove 54. The clamping plate 553 penetrates through the short block 552 and is slidably connected with the short block 552. The clamping plate 553 is fixed with a pulling plate 554 at one end. The clamping plate 553 is sleeved with a spring 555 on the surface, and the both ends are respectively fixed on the surface of the short block 552 and the pulling plate 554. The clamping plate 553 is provided with an unlocking groove 556 at one end, which is matched with the unlocking plate 57. The clamping plate 553 is fixed with a positioning block 557.

[0088] The end of the clamping plate 553 and the fixing block 53 are provided with inclined surfaces. Through such arrangement, when the fixing block 53 rotates and is pressed by the clamping plate 553, the clamping plate 553 and the pulling plate 554 can move, and then the spring five 555 deforms. When the clamping plate 553 corresponds to the clamping groove 54, the end of the clamping plate 553 is inserted into the clamping groove 54 under the action of the rebound of the spring five 555, the fixing block 53 and the connecting plate 56 are limited, and thus the unfolded piece 51 is limited. The unlocking groove 556 and the lower end of the unlocking plate 57 are provided with inclined surfaces. With the upward movement of the moving seat 14, the fixing piece 55 moves upward, the clamping plate 553 is pressed by the rear end of the unlocking groove 556 and the unlocking plate 57, and thus the clamping plate 553 moves, the end of the clamping plate 553 is separated from the clamping groove 54, the fixing of the fixing block 53 is released, and the movable plate 512 and the rubber wheel 513 are reset under the action of the torsional spring two 514.

[0089] In use, the operation of the punch press 12 drives the moving seat 14 and the punch 15 to move downward. When the pressing plate 212 does not contact the lower die 13, the pressing plate 212 moves with the moving seat 14. After the pressing plate 212 contacts the lower die 13, the spring one 213 is compressed with the downward movement of the moving seat 14, and the generated elastic force acts on the pressing plate 212 to press and hold the aluminum plate. After the grinding wheel 22 moves downward with the lower pressing piece 21 and contacts the aluminum plate, the corresponding part of the aluminum plate that is subjected to stamping is pressed and held.

[0090] After the aluminum plate is subjected to stamping to form a bottle cap in the mold cavity 17, and the suction piece 32 generates suction force under the cooperation of the rubber ring 33 with the downward movement of the top pop piece 31, the bottle cap can be adsorbed and fixed. Then, after the punch 15 completes stamping and moves upward, the bottle cap formed in the mold cavity 17 can be limited, avoiding that the bottle cap is attached to the surface of the punch 15, causing that the bottle cap cannot be removed, and affecting subsequent stamping and forming of the bottle cap. Finally, in the process of upward movement of the punch 15, the grinding wheel 22 can rotate under the driving of the driving piece 24 and the transmission piece 23, and then the grinding wheel 22 contacts the bottle cap to grind the breakage of the bottle cap and remove burrs.

[0091] In the process of the punch 15 moving upward after separating from the lower die 13, the piston 324 moves upward and resets under the action of the top pop piece 31, the air hole 323 is communicated with the atmosphere after the blocking frame 327 removes the shielding of the air hole 323, and then the top pop piece 31 is communicated with the atmosphere, and the fixing of the bottle cap is released. Through the operation of the fan 6, the demolded bottle cap can be blown to guide the bottle cap into the discharging frame 7 for discharging and collecting.

[0092] In summary, through the demolding polishing assembly 2 (downward pressure piece 21 + polishing wheel 22 + ratchet 231 transmission), compared with the prior art, the polishing wheel 22 is automatically rotated when the punch 15 moves up, the demolding limiting and burr removal are synchronously completed, the traditional manual intervention is avoided, and the ejection fixing assembly 3 is through the rubber ring 33 adsorption + elastic piece one 34 ejection mechanism: when stamping: air cylinder 322 and piston 324 linkage generates negative pressure adsorption fixed bottle cap, when demolding: spring two 314 reset push top block 312 and elastic piece one 34 elastic force auxiliary pop out.

[0093] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application, which should be covered in the scope of the claims of the present application.
