Description

Technical Field

[0001] The invention relates to the field of terminal stamping die design, and in particular to a stamping mechanism for forming terminals of a desired shape and a stamping production process thereof. Background Art

[0002] Please combine Figure 1 and Figure 2 As shown, the stamping die 10 commonly used in the current industry's strip terminal stamping production process includes a stamping die 11 and a bending die 12. The stamping die 11 is set close to the die feed end 13, and the bending die 12 is set close to the die discharge end 14. The existing strip terminal stamping production process is to first stamp and bend the metal sheet material into the desired shape of the strip terminal. Specifically, the metal sheet material fed from the die feed end 13 is stamped and blanked into a terminal strip in the stamping die 11, and then the electroplating part and support part of each strip terminal 20 in the terminal strip are bent into the desired shape in the bending die 12, and then discharged from the die discharge end 14 and wound into a whole roll of terminal strip on a reel. Next, the strip terminal 20 undergoes post-process electroplating and embedded injection molding operations.

[0003] Please combine Figure 3 and Figure 4 As shown in FIG. 1 , the plated portion of the existing strip terminal 20 is bent to form a bent portion. Specifically, as Figure 3 The first plating portion 21, the second plating portion 22 and the third plating portion 23 shown in FIG are bent to form corresponding Figure 4 The first bending portion 21A, the second bending portion 22A and the third bending portion 23A shown in the figure are formed on the ground side of the strip terminal 20 by bending downward; the third bending portion 23A is formed on the sky side of the strip terminal 20 by bending upward.

[0004] Since the strip terminal 20 has a slender structure and a high bend, when the terminal strip is loaded on a reel, the stress point of the terminal strip is the bend. In order to avoid deformation during packaging and transportation, a protective leg is required to support the terminal strip and to suspend the bend to protect the terminal functional area from external force collision and deformation. The support portion of the existing strip terminal 20 is bent to form a protective leg. Specifically, Figure 3 The first support portion 24 and the second support portion 25 shown in FIG are bent to form the following Figure 4The first protective leg 24A and the second protective leg 25A are bent upward and formed on the sky side of the strip terminal 20, and the first protective leg 24A and the second protective leg 25A are higher than the third bent portion 23A to overhead the third bent portion 23A; Figure 3 The third support portion 26 and the fourth support portion 27 shown in FIG are bent to form the following Figure 4 The third and fourth protective legs 26A, 27A shown are bent downward on the ground side of the strip terminal 20. These legs are higher than the first and second bent portions 21A, 22A, to lift them above the first and second bent portions 21A, 22A. However, due to the thin material thickness and weak strength of the strip terminal 20, deformation can occur during production, seriously affecting the subsequent automated injection molding process for the strip terminal and even causing damage to components in the injection mold.

[0005] At the same time, since multiple protective feet are added to the material strip terminals 20, the layer height of the terminal material strip is too high when it is packaged and collected, resulting in a small number of terminal material strip windings in each reel, which increases the reel switching frequency in the stamping, bending, electroplating, and embedded injection molding processes, increases the material change time, and causes loss of the head and tail materials of each reel of terminal material strip, thereby increasing production costs. Summary of the Invention

[0006] In order to solve the problems existing in the prior art, the invention provides a material strip terminal stamping and forming system, which can avoid the deformation of the material strip terminals, thereby ensuring the smooth progress of subsequent production operations, maintaining quality and improving production efficiency; while reducing the consumption of packaging materials and transportation costs, it also reduces the head and tail material loss ratio of each roll of full-flat terminal material strip.

[0007] In order to achieve the above-mentioned purpose, the invention adopts the following technical solutions:

[0008] A strip terminal stamping and forming system includes a strip terminal stamping and forming process and a strip terminal stamping and forming mechanism; wherein the production steps of the strip terminal stamping and forming process are as follows:

[0009] Step 1: The metal sheet material is punched through a full-plane punching die to form a full-plane terminal strip consisting of full-plane terminals;

[0010] Step 2: The full-planar terminals on the full-planar terminal strip are electroplated by a terminal electroplating device;

[0011] Step three, the full-flat terminal on the full-flat terminal strip after the electroplating operation is completed is bent into a terminal strip of the desired shape by a terminal bending and forming device, so that the full-flat terminal strip is processed into a bent terminal strip consisting of a terminal strip of the desired shape;

[0012] Step 4: the bent terminal strip is directly sent to an injection molding die, and the injection molding die directly performs an injection molding operation on the strip terminals of the required shape on the bent terminal strip without interference.

[0013] As described above, a strip terminal stamping and forming system, the strip terminal stamping and forming mechanism comprises a terminal stamping device, a terminal electroplating device, a terminal bending and forming device and an injection molding die which are sequentially assembled; wherein,

[0014] The terminal stamping device includes a metal sheet material feed end, a full-flat stamping die, and a full-flat terminal discharge end, which are sequentially assembled; the full-flat stamping die stamps the metal sheet material fed from the metal sheet material feed end to form a full-flat terminal strip composed of full-flat terminals, and the full-flat terminal discharge end outputs the full-flat terminal strip to the terminal electroplating device;

[0015] Terminal plating device, for electroplating the full-planar terminals of the full-planar terminal strip;

[0016] The terminal bending and forming device comprises a full-plane terminal feeding end, a bending and forming die, a pulling mechanism and a bending and forming terminal discharging end which are sequentially assembled; wherein,

[0017] The full-plane terminal feeding end feeds the full-plane terminal strip electroplated by the terminal electroplating device; the bending forming die bends the full-plane terminals in the full-plane terminal strip into strip terminals of required shapes, and the strip terminals of required shapes constitute the bent terminal strip;

[0018] The pulling mechanism includes a feeding die, a feeding punch, and a spring device; the spring device is connected to the feeding die, the feeding punch abuts against the feeding die, and the feeding die is set corresponding to the bent terminal strip, so that when the feeding punch pushes the feeding die, the bent terminal strip is synchronously driven to be output from the bent terminal discharge end to the injection molding mold;

[0019] The injection molding mold directly performs the injection molding operation on the terminal strip with the required shape on the bent terminal strip.

[0020] In the above-mentioned strip terminal stamping and forming system, the contact surface between the feeding punch and the feeding die is an inclined surface.

[0021] As described above, a strip terminal stamping and forming system is provided on the full-plane terminal, and a plating portion and a supporting portion are provided on the full-plane terminal. The plating portion is bent by a bending forming die to form a bending portion, and the bending portion is formed on the sky side and the ground side of the full-plane terminal, and the bending portion arranged on the sky side of the full-plane terminal is higher than the bending portion arranged on the ground side of the full-plane terminal; the supporting portion is bent by a bending forming die to form a protective foot, and the protective foot is formed on the ground side of the full-plane terminal, and the protective foot is higher than the bending portion arranged on the ground side of the full-plane terminal.

[0022] As for the above-mentioned strip terminal stamping and forming system, its characteristic is that the height of the first protective leg and the second protective leg should be lower than the height of the third bending portion.

[0023] Compared with the existing technology, the technical solution provided by the invention has the following beneficial effects:

[0024] First, the invented strip terminal stamping and forming system aims to solve the problem that the strip terminals in the existing technology are easily deformed after bending, which leads to the subsequent automatic injection molding production not going smoothly. A special full-flat stamping mold is used to punch the terminal products into full-flat terminal strips. After the electroplating operation, and at the front end of the subsequent injection molding mold, a terminal bending forming mold is used to bend the full-flat strip terminals into the required shape. This can avoid deformation of the strip terminals, thereby ensuring the smooth progress of subsequent production operations, maintaining quality and improving production efficiency.

[0025] Secondly, the invented terminal strip stamping and forming system is equipped with a full-flat stamping die to punch the terminal strip into a full-flat terminal strip for packaging the entire roll of strip. The layer height of the full-flat terminal strip is only the thickness of the metal sheet material, which can greatly increase the number of wound products on each reel (from the usual 5,000 / reel to 25,000 / reel), reduce the reel switching frequency of stamping, electroplating, and injection molding, and improve production efficiency; at the same time, reduce the consumption of packaging materials and transportation costs; and reduce the loss ratio of the head and tail materials of each roll of full-flat terminal strip.

[0026] Third, the contact surface between the feeding punch and the feeding die of the material strip terminal stamping forming system of the invention is set as an inclined surface, which can further enhance the automatic and smooth pulling function of the bent terminal material strip.

[0027] Fourth, the bending die is located at the front end of the injection molding die. The top side of the fully flat terminal, after the electroplating process, is unaffected by external forces and will not deform, eliminating the need for protective legs. Eliminating the protective legs enhances the overall strength of the terminal strip in the desired shape. BRIEF DESCRIPTION OF THE DRAWINGS

It should be understood that the specific embodiments described herein are only used to explain the invention and are not intended to limit the invention.

[0046] In the claims, description and above-mentioned drawings of the invention, unless otherwise expressly defined, if the terms "fixed connection" or "fixed connection" are used, they should be understood in a broad sense, that is, any connection method without displacement relationship and relative rotation relationship between the two parties, that is to say, including non-detachable fixed connection, detachable fixed connection, integral connection and fixed connection through other devices or elements.

[0047] In the claims, description and drawings of the present invention, if the terms "include", "have" and their variations are used, they are intended to mean "including but not limited to".

[0048] Now combined Figures 5 to 14 As shown, a strip terminal stamping and forming system is invented, including a strip terminal stamping and forming process and a strip terminal stamping and forming mechanism.

[0049] The strip terminal stamping and forming mechanism of the present invention comprises a terminal stamping device 100, a terminal electroplating device, a terminal bending and forming device 200 and an injection molding die which are sequentially assembled.

[0050] Please combine Figure 9 and Figure 10 As shown, the terminal stamping device 100 of the present invention includes a metal sheet material feeding end 110, a full-plane stamping die 120 and a full-plane terminal discharging end 130 which are sequentially assembled.

[0051] The full-plane stamping die 120 stamps the metal sheet material fed from the metal sheet material feed end 110 to stamp the metal sheet material into a full-plane terminal strip composed of full-plane terminals 300, and the full-plane terminal strip is output to the terminal electroplating device from the full-plane terminal discharge end 130.

[0052] Specifically, the full-plane stamping die 120 includes a full-plane stamping upper die 120A and a full-plane stamping lower die 120B. A full-plane stamping punch 122 is provided on a full-plane stamping upper die base 121 of the full-plane stamping upper die 120A, and a full-plane stamping die 124 is provided on a full-plane stamping lower die base 123 of the full-plane stamping lower die 120B. The shapes of the full-plane stamping punch 122 and the full-plane stamping die 124 are machined to vary according to the shape of the full-plane terminal 300. The full-plane stamping punch 122 and the full-plane stamping die 124 cooperate with each other to stamp a metal sheet material, thereby forming the metal sheet material into a full-plane terminal strip composed of the full-plane terminals 300.

[0053] The first step of the production process of the strip terminal stamping forming process is to first feed the metal sheet material from the metal sheet material feeding end 110 and punch it through the full-plane stamping die 120 to form a full-plane terminal strip. Figure 5 and Figure 6 As shown, the strip terminals on the full-flat terminal strip are full-flat terminals 300. The full-flat terminal strip composed of full-flat terminals 300 can avoid deformation problems of each strip terminal thereon, thereby ensuring the smooth progress of subsequent production operations, maintaining quality and increasing production capacity. In addition, when the full-flat terminal strip of the invention is packaged and collected, the layer height of the full-flat terminal strip is only the thickness of the metal sheet material, which can significantly increase the number of wound products per reel (from the usual 5,000 / reel to 25,000 / reel), reduce the reel switching frequency for stamping, electroplating, and injection molding, and improve production efficiency; at the same time, it reduces the consumption of packaging materials and transportation costs; and reduces the loss ratio of the head and tail materials of each reel of full-flat terminal strip.

[0054] The second step of the present invention's strip terminal stamping process is to electroplate the full-plane terminal strip composed of the full-plane terminals 300 through the terminal electroplating device. Figure 5 and Figure 6 As shown, the fully planar terminal 300 of the present invention is provided with one or more plating portions, and the terminal plating device performs plating operations on the one or more plating portions provided on the planar terminal 300. In this embodiment, the fully planar terminal 300 is provided with a first plating portion 310, a second plating portion 320, and a third plating portion 330.

[0055] The third step of the present invention's strip terminal stamping process is to bend the full-plane terminal 300 on the full-plane terminal strip through the terminal bending and forming device 200 to bend the full-plane terminal 300 into the desired shape strip terminal 300A. Figure 7 As shown, the one or more electroplating parts are bent by the bending forming device 200 of the present invention to form one or more bending parts accordingly.

[0056] Please combine Figure 11 and Figure 12 As shown, the terminal bending and forming device 200 of the present invention is used to achieve the bending process of the full-plane terminal 300 and the drawing of the material inside the mold. The terminal bending and forming device 200 includes a full-plane terminal feed end 210, a bending forming mold 220, a drawing mechanism 230, and a bent terminal discharge end 240.

[0057] The flat terminal strip plated by the terminal plating device is fed from the flat terminal feed port 210 to the bending die 220. The bending die 220 bends the flat terminals 300 in the flat terminal strip into strip terminals 300A of desired shape. The strip terminals 300A of desired shape constitute the bent terminal strip. The bent terminal strip is pulled by the pulling mechanism 230 and discharged from the bent terminal discharge port 240.

[0058] Specifically, the bending forming die 220 includes an upper bending forming die 220A and a lower bending forming die 220B. The upper bending forming die 220A is provided with a bending punch 221, and the lower bending forming die 220B is provided with a bending die 222. The shapes of the bending punch 221 and the bending die 222 are machined according to the shape of the desired shape of the strip terminal 300A. The bending punch 221 and the bending die 222 cooperate with each other to bend the full-flat terminals 300 in the full-flat terminal strip, so that the full-flat terminal strip is formed into a bent terminal strip consisting of the strip terminals 300A of the desired shape.

[0059] The fully flat terminal 300, after the electroplating process, is fed from the fully flat terminal feed port 210 and bent into the desired shape strip terminal 300A by the bending forming die 220. This allows the fully flat terminal strip to be processed into a bent terminal strip consisting of the desired shape strip terminals 300A. Specifically, the bending forming die 220 bends the plating portion and support portion of the fully flat terminal 300 to form the desired shape strip terminal 300A having a bent portion and protective legs.

[0060] Specifically, the electroplating portion provided on the full-plane terminal 300 is bent by the bending forming mold 220 of the invention to form a bending portion, and the bending portion is formed on the sky side and the ground side of the full-plane terminal 300, and the bending portion provided on the sky side of the full-plane terminal 300 is higher than the bending portion provided on the ground side of the full-plane terminal 300.

[0061] The support portion provided on the full-plane terminal 300 is bent by the inventive bending forming mold 220 to form a protective foot. The protective foot is formed on the ground side of the full-plane terminal 300, and the protective foot is higher than the bending portion provided on the ground side of the full-plane terminal 300.

[0062] In this embodiment, the fully flat terminal 300 after the electroplating operation is completed is provided with the following Figure 5 The first plating portion 310, the second plating portion 320 and the third plating portion 330 shown in FIG are formed into the following shapes after being bent by the bending forming mold 220 of the invention. Figure 7 The first, second, and third bent portions 310A, 320A, and 330A are shown. The first and second bent portions 310A, 320A are bent downward on the ground side of the full-plane terminal 300; the third bent portion 330A is bent upward on the sky side of the full-plane terminal 300; and the height of the third bent portion 330A is greater than that of the first and second bent portions 310A, 320A.

[0063] The fully flat terminal 300 after the electroplating operation is completed is provided with Figure 5 The first supporting portion 340 and the second supporting portion 350 shown in FIG. 3 are formed by bending the first supporting portion 340 and the second supporting portion 350 by the bending forming mold 220 of the invention. Figure 7 The first and second protective legs 340A and 350A are bent downward on the ground side of the full-plane terminal 300 and are higher than the first and second bent portions 310A and 320A to lift the first and second bent portions 310A and 320A above the ground.

[0064] Since the bending forming mold 220 is arranged at the front end of the injection molding mold, the full-plane terminal 300 that has completed the electroplating operation will immediately enter the injection molding mold after exiting the bending forming mold 220. The third bend portion 330A is formed by bending upward on the top side of the full-plane terminal 300. The top side of the full-plane terminal 300 is not subject to external forces and will not deform, so there is no need to set protective legs. Eliminating the provision of higher protective legs on the top side of the full-plane terminal 300 can enhance the overall strength of the required shape strip terminal 300A. Conversely, if the first bend portion 310A and the second bend portion 320A are formed by bending downward on the ground side of the full-plane terminal 300, the first protective legs 340A and the second protective legs 350A still need to be provided. The first bend portion 310A and the second bend portion 320A need to be supported overhead to prevent the electroplated first bend portion 310A and the second bend portion 320A from being deformed by external forces.

[0065] A protective foot needs to be set on the ground side of the full-plane terminal 300. The higher the protective foot is, the worse the strength will be. Therefore, further, the height of the first protective foot 340A and the second protective foot 350A should be lower than the height of the third bending portion 330A to further improve the overall strength of the required shape strip terminal 300A.

[0066] The bent terminal strip of the invention is automatically moved to the bent terminal discharge end 240 via the pulling mechanism 230 .

[0067] For details, please combine Figure 13 and Figure 14 As shown, the inventive pulling mechanism 230 includes a feed die 231, a feed punch 232, and a spring device 233. The spring device 233 is connected to the feed die 232, causing the feed die 232 to move back and forth linearly. The feed die 232 is configured to correspond to the bent terminal strip, thereby synchronously driving the bent terminal strip. The feed punch 232 abuts against the feed die 231, pushing the feed die 231 toward the bent terminal outlet 240.

[0068] When the feeding punch 232 does not move downward to push the feeding die 231, the feeding die 231 is at the feeding initial point under the elastic force of the spring device 233 (the feeding die 231 is as shown in FIG. Figure 13 The feeding die 231 does not touch the bent terminal strip.

[0069] When the feeding punch 232 moves downward and pushes the feeding die 231, the feeding die 232 simultaneously contacts the bent terminal strip (the feeding die 232 is in a closed state), and the feeding die 232 overcomes the elastic force of the spring device 233 and simultaneously drives the bent terminal strip to move toward the bent terminal discharge end 240 (the feeding die 232 is in a closed state). Figure 14 The bent terminal discharge end 240 outputs the bent terminal strip to the injection molding die.

[0070] Furthermore, to achieve the automatic and smooth pulling function of the bent terminal strip, the contact surfaces between the feed punch 232 and the feed die 231 of the present invention are configured as inclined surfaces. These inclined surfaces include a punch inclined surface 232A provided on the feed punch 232 and a die inclined surface 231A provided on the feed die 231. When the punch press drives the feed punch 232 downward, the feed die 231 closes. Under the action of the inclined punch surface 232A of the feed punch 232, the feed die 231 overcomes the elastic force of the spring device 233 (compression spring) and simultaneously pulls the bent terminal strip to move.

[0071] The fourth step of the invented strip terminal stamping forming process is that the bent terminal strip discharged from the bent forming terminal discharge end 240 does not need to be packaged again. The bent terminal strip is directly sent from the bent forming terminal discharge end 240 to the injection molding mold, and the injection molding mold directly performs the injection molding operation on the required shape strip terminal 300A on the bent terminal strip without interference.

[0072] The foregoing description shows and describes preferred embodiments of the invention. As previously mentioned, it should be understood that the invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the invention is adaptable to various other combinations, modifications, and environments and is capable of modification within the scope of the inventive concept described herein, through the teachings above, or through techniques or knowledge in the relevant art. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the invention are intended to be within the scope of the appended claims.
