[0048] The following will be combined Figures 1 to 15 Here we introduce the stamping and forming device provided in the embodiment of the present utility model.

[0049] According to an embodiment of the present invention, a stamping and forming device is provided for performing stamping and cutting operations on a device to be stamped 300. Figure 1 、 Figure 2 、 Figure 3 、 Figure 13 as well as Figure 15 As shown, the stamping and forming device includes an upper die assembly 10 and a lower die assembly 20, wherein the upper die assembly 10 includes a stamping portion 11 and a cutting portion 12, and the lower die assembly 20 is arranged below the upper die assembly 10, and the lower die assembly 20 includes a forming groove 21. The upper die assembly 10 can reciprocate in the up and down directions so that the stamping portion 11 cooperates with the forming groove 21 to stamp the component to be stamped 300, wherein the stamping portion 11 is movably connected to the cutting portion 12. After stamping the component to be stamped 300, the cutting portion 12 can continue to move relative to the stamping portion 11 to cut the component to be stamped 300, thereby obtaining the target component 200 from the component to be stamped 300.

[0050] According to the stamping and forming device of the present invention, when the upper die assembly 10 moves downward, the stamping portion 11 cooperates with the forming groove 21 of the lower die assembly 20, and the device 300 to be stamped is deformed according to the shape of the forming groove 21 under the pressure from the upper die assembly 10, thereby forming the device 300 to be stamped with a preliminary shape through the stamping operation. After that, the cutting portion 12 in the upper die assembly can continue to move downward relative to the stamping portion 11 to cut the device 300 to be stamped with a preliminary shape, thereby forming the target device 200. Subsequently, the upper die assembly 10 moves upward and returns to its initial position to prepare for the next round of stamping and cutting operations. At this time, the target device 200 can also be removed manually to make room for a new device 300 to be stamped.

[0051] According to the present application, the device to be punched 300 can be punched in its entirety or only partially. The following describes a specific embodiment using an electronic device having multiple connection terminals as an example. However, it should be noted that the present application is not limited thereto.

[0052] Figure 15 This is a schematic diagram of the structure of a device to be punched with connection terminals before and after forming according to an embodiment of the present invention. Figure 15 As shown, after punching and cutting, the connection terminals of the device to be punched 300 can form certain grooves and remove excess end portions to form the target device 200 .

[0053] According to the described utility model stamping and forming device, the stamping operation and the cutting operation can be completed through one up and down movement, which reduces the time required for the operation and thus improves production efficiency.

[0054] In an embodiment of the present application, the shape of the forming groove 21 should match the expected shape of the component 300 to be punched after the stamping operation (for example, it can be the preliminary shape mentioned in the above embodiment) to ensure that the component 300 to be punched can obtain the desired shape after stamping.

[0055] In the embodiment of the present application, the forming groove 21 can be on the lower mold assembly 20, and the groove is formed by internal removal. For example, it can be on the device support seat 90 to be described below.

[0056] As an example, the forming groove 21 is stepped. This allows, in conjunction with the stamping portion 11, to form a target device 200 having stepped connecting terminals. The forming grooves 21 are located at the edges of the lower die assembly 20. This prevents interference with other components when the device 300 to be punched deforms and moves during stamping. Furthermore, placing the forming grooves at the edges of the lower die assembly 20 facilitates the removal of excess terminal ends during the subsequent cutting process, thereby not only forming the target device 200 having stepped connecting terminals but also facilitating cutting operations.

[0057] According to the present application, during the stamping process, the punched component 300 will undergo some deformation. If the cutting operation and the stamping operation are performed simultaneously, it is inconvenient to control the cutting accuracy. Therefore, according to the embodiment of the present application, the stamping operation is performed first, and the cutting operation is performed after the stamping operation is completed.

[0058] In some embodiments, there is a certain gap between the cutting portion 12 and the stamping portion 11, and this gap allows the lower end of the stamping portion 11 to protrude relatively from the lower end of the cutting portion 12 when the upper mold assembly 10 moves downward to close to the lower mold assembly. In this way, the stamping portion 11 reaches the component to be punched 300 in advance, and the cutting portion 12 reaches the component to be punched 300 a predetermined time after the stamping portion 11 reaches the component to be punched 300, thereby achieving the purpose of first punching by the stamping portion 11 and then cutting by the cutting portion 12.

[0059] According to the present application, the stamping part 11 limits the downward movement of the cutting part 12, and can prevent the cutting part 12 from acting on the device to be punched 300 before the stamping part 11. It can ensure that in each reciprocating motion, the stamping operation is always performed first, and then the cutting operation is performed, thereby ensuring the accuracy of cutting.

[0060] According to the present application, after the punching section 11 reaches the target component 300, the cutting section 12 can continue to move relative to the punching section 11. In some embodiments, a buffer member 30 is provided between the punching section 11 and the cutting section 12. Specifically, the buffer member 30 is located between the upper portion of the punching section 11 and the cutting section 12. The buffer member 30 has a certain elastic deformation force and can deform under the action of pressure. Therefore, after the punching section 11 completes the punching operation on the target component 300, the cutting section 12 can continue to move downward under the drive of an external force to perform the cutting operation.

[0061] Specifically, when the punching action of the punching part 11 is completed, the punching part 11 abuts against the lower mold assembly 20. At this time, the cutting part 12 will squeeze the buffer part 30 to deform while continuing to be subjected to force, providing the necessary moving space for the cutting part 12 to continue to move downward, so that it can continue to move downward relative to the punching part 11 to complete the cutting operation of the excess part of the edge of the punched component 300. In this way, the smooth progress of the cutting operation can be ensured.

[0062] At the same time, thanks to the presence of the buffer 30, the cutting section 12 can continue to move downward in a more stable state when subjected to pressure, thereby accurately completing the cutting operation and ensuring product quality. Moreover, when the cutting section 12 cuts the component to be punched, the buffer 30 can absorb part of the impact force, preventing the cutting section 12 from directly impacting the stamping section 11, helping to protect the cutting section 12 and the stamping section 11, extending the service life of the stamping and forming device, and reducing noise impact.

[0063] In addition, under the elastic force of the buffer member 30, the cutting portion 12 can quickly return to its original position after cutting is completed. In this way, the two processes of stamping and cutting can be smoothly connected without additional waiting time or adjustment, thereby improving production efficiency.

[0064] In some embodiments, the buffer member 30 is at least one of a spring and a buffer pad. Specifically, the buffer pad is a polyurethane pad. Using a polyurethane pad as the buffer member 30 can meet the working environment requirements of the stamping and forming device (for example, temperature, pressure, and rebound force, etc.), and can operate stably for a long time to ensure the service life of the stamping and forming device.

[0065] In some embodiments, the buffer 30 has at least two opposing and parallel surfaces. In this way, the buffer 30 with parallel surfaces can stably withstand the pressure from the stamping portion 11 and the cutting portion 12, helping to ensure that the cutting portion 12 can continue to move downward smoothly when subjected to force, thereby completing the cutting more accurately to improve precision. The buffer 30 with parallel surfaces can more evenly distribute the pressure it is subjected to, helping to prevent damage or deformation of the buffer 30 due to excessive local pressure, thereby extending its service life. In addition, the buffer 30 with parallel surfaces is more convenient to install and position, and can make it easier for the buffer to match the contact surfaces of the stamping portion 11 and the cutting portion 12, thereby ensuring the correct installation position and good contact effect.

[0066] According to the present application, the stamping forming device may further include a driving unit, which is connected to the upper mold assembly 10 and drives the upper mold assembly 10 to reciprocate. Here, the driving unit can provide power and enable the upper mold assembly to reciprocate according to a predetermined trajectory (up and down movement) and a predetermined speed. In this way, it is possible to facilitate the realization of automated and efficient production.

[0067] In some embodiments, the type of the driving unit can be hydraulic drive, pneumatic drive, electric drive, etc. Those skilled in the art can choose according to actual needs, and this application does not impose too many restrictions on this.

[0068] According to the present application, the cutting unit 12 can cut the punched device 300 to form the target device 200 .

[0069] like Figures 4 to 7 As shown, the cutting portion 12 includes a connecting boss 121 and a cutting main body portion 122 connected to the connecting boss 121, the connecting boss 121 is connected to the driving portion, the connecting boss 121 is located above the cutting main body portion 122 and protrudes laterally relative to the cutting main body portion 122, the stamping portion 11 is movably connected to the cutting main body portion 122, the buffer member 30 is arranged between the connecting boss 121 and the upper end of the stamping portion 11, and the lower end portion of the cutting main body portion 122 serves as the punch end of the cutting portion 12, for cutting the device 300 to be punched.

[0070] In this embodiment, the connecting boss 121 serves as the connection between the cutting unit 12 and the drive unit. It is located above the cutting body 122 and projects laterally relative to the cutting body 122. This facilitates connection with the drive unit and ensures that the cutting unit 12 as a whole can move under the action of the driving force. The lower end of the cutting body 122 serves as the punch end of the cutting unit 12, which is used to cut the component 300 to be punched.

[0071] In these embodiments, a buffer member 30 is provided between the connecting boss 121 and the upper end of the punching portion. The deformation of the buffer member 30 provides the necessary space for the cutting portion 12 to continue its downward movement, ensuring a smooth cutting operation. Furthermore, when the punching portion 11 punches the component 300 to be punched, the buffer member 30 absorbs some of the impact force, protecting both the cutting portion 12 and the punching portion 11.

[0072] According to the present application, the stamping portion 11 is movably connected to the cutting portion 12. Specifically, the cutting portion 12 includes a connecting boss 121 and a cutting body portion 122 connected to the connecting boss 121. The stamping portion 11 is movably connected to the cutting body portion 122. As for the specific form of this movable connection, those skilled in the art can select it according to the actual needs of the substrate. For example, the cutting body portion 122 can be connected to the stamping portion 11 by means of a slide rail or a slider. For another example, an elongated hole 123 extending in the vertical direction can be provided on the cutting body portion 122, and the stamping portion 11 is movably connected to the elongated hole 123 by a connecting bolt 118.

[0073] In these embodiments, the cutting body 122 is provided with a vertically extending elongated hole 123, and a connecting bolt 118 is passed through the punching portion 11 and the elongated hole 123, and is fixed to the cutting body 122 by a nut or other fastener, so that the cutting portion 12 can continue to move downward relative to the punching portion 11 after punching is completed. In addition, this connection method makes the connection between the punching portion 11 and the cutting portion 12 more reliable, which can meet the needs of punching.

[0074] In some embodiments, the cutting body portion 122 and the connecting boss 121 are formed in an L-shape, so that the stability of the formed cutting portion 12 can be ensured.

[0075] In some embodiments, the cutting body 122 and the connecting boss 121 are integrally formed. This ensures the overall strength of the cutting portion 12 and prevents them from cracking or separating during long-term use. It should be noted that this application does not limit the two to being integrally formed. Those skilled in the art can, based on the teachings of this application, configure the two as separate structures and connect them in a reliable manner.

[0076] In some embodiments, the lower end of the cutting body 122 is the punch end of the cutting part 12. Here, the punch end of the cutting part 12 can be made of a material with high hardness and high wear resistance to ensure that its cutting performance during use is more durable.

[0077] According to the present application, the stamping portion 11 can be configured based on the specific requirements of the component 300 to be stamped. As an example, the stamping portion 11 includes a main body 111 and a stamping protrusion 112 protruding outward from the lower end of the main body 111. When the buffer 30 is in the initial state, the lower end of the stamping protrusion 112 protrudes beyond the punch end of the cutting portion 12. The stamping protrusion 112 can abut against the lower die assembly 20 outside the forming groove 21 to stamp the component 300 to be stamped.

[0078] In an embodiment of the present application, the driving part can simultaneously drive the stamping part 11 and the cutting part 12. When the stamping part 11 and the cutting part 12 both move at the same time, the buffer 30 located between the stamping part 11 and the cutting part 12 can be in a non-deformed state or in a slightly deformed state. At this time, the buffer 30 is in an initial state. When the punch end of the stamping part 11 abuts against the lower die assembly 20, the driving part can drive the cutting part 12 to squeeze the buffer 30. In this case, the buffer 30 is deformed or deformed to a large extent. At this time, the buffer 30 is in a deformed state, thereby providing the necessary moving space for the cutting part 12 to continue to move downward. In this way, the cutting part 12 can continue to move downward relative to the stamping part 11.

[0079] In these embodiments, the main body 111 is relatively thick. As the main component of the stamping part 11, it can provide sufficient strength and stability to cope with the pressure and impact force during the stamping process, and avoid damage to the stamping part 11 or poor stamping effect. In addition, the main body 111 is provided, and it can also be connected to the driving part, the connecting boss 121, etc., so as to avoid affecting various aspects of the performance of the stamping convex part 112 as the punch end. The stamping convex part 112 is the part of the stamping part 11 that performs stamping. When the buffer part 30 is in the initial state, the lower end of the stamping convex part 112 protrudes from the punch end of the cutting part 12, which can ensure that during the stamping process, the stamping convex part 112 can first contact the device 300 to be punched and apply the required stamping force, thereby facilitating the realization of the first stamping function.

[0080] In some embodiments, the main body 111 and the stamping protrusion 112 are integrally formed. This ensures the overall strength of the stamping portion 11 and prevents cracking or separation during long-term use. It should be noted that this application does not limit the two to being integrally formed. Those skilled in the art can, based on the teachings of this application, configure the two as separate structures and connect them in a reliable manner.

[0081] In some embodiments, the lower end of the stamping protrusion 112 is the punch end of the stamping part 11. Here, the punch end of the stamping part 11 can be made of a material with high hardness and high wear resistance to ensure the durability of its stamping performance during use.

[0082] In some embodiments, a clearance groove 113 and a limiting protrusion 114 located on at least one side of the clearance groove 113 are formed at the lower end of the stamping protrusion 112. The component to be punched 300 is stamped through the bottom wall of the clearance groove 113, and the limiting protrusion 114 can abut against the lower mold assembly 20 on the outside of the forming groove 21.

[0083] like Figure 4 、 Figure 5 as well as Figure 8 as well as Figure 9 As shown, the stamping protrusion 112 is a ridge formed on the lower edge of the main body 111. The ridge includes the aforementioned clearance groove 113 and limiting protrusions 114 located on both sides of the clearance groove 113. In this way, the limiting protrusions 114 on both sides can provide more balanced support, ensuring that the clearance groove 113 can stamp the target device 300 smoothly and consistently, thereby ensuring the quality of the target device 200 formed.

[0084] In these embodiments, before the stamping operation begins, there is a certain gap between the limiting protrusion 114 and the lower die assembly 20, and the bottom wall of the clearance groove 113 is above the device to be stamped 300. When the limiting protrusion 114 gradually approaches the lower die assembly until it contacts it, the bottom wall of the clearance groove 113 presses against the device to be stamped 300 to deform it, thereby achieving the desired deformation or processing by applying a stamping force. In addition, there is a height difference between the clearance groove 113 and the limiting protrusion 114. This height difference can ensure that after stamping, the device to be stamped 300 can be effectively avoided, and the limiting protrusion 114 abuts against the lower die assembly 20 to prevent the stamping portion 11 from continuing to move downward, thereby preventing the device from being broken or excessively deformed.

[0085] According to the present application, for positioning the component 300 to be punched, a pressing plate can be added to the upper mold assembly 10 to limit the vertical movement of the component 300 to be punched.

[0086] like Figure 3 、 Figure 4 、 Figure 11 and Figure 12 An elastic pressing plate 40 is fixedly provided on one side of the main body 111. The elastic pressing plate 40 is arranged corresponding to the clearance groove 113 and protrudes from the lower end of the punching protrusion 112. When the punching part 11 moves downward, the elastic pressing plate 40 presses against the bottom wall of the clearance groove 113 before pressing the component 300 to be punched.

[0087] like Figure 8 、 Figure 9 、 Figure 11 and Figure 12 As shown, a mounting hole 116 is formed on the main body 111 of the stamping part 11 , and the elastic pressing plate 40 is fixed to the stamping part 11 through a fastener passing through the mounting hole 116 .

[0088] In these embodiments, the elastic pressing plate 40 protrudes from the lower end of the stamping protrusion 112. When the stamping portion 11 moves downward, the elastic pressing plate 40 can press against the component to be punched 300 before the bottom wall of the clearance groove 113, so as to preliminarily fix and position the component to be punched 300, ensuring that it will not move or deflect during the stamping process. It also provides a certain buffer to avoid displacement or damage due to excessive impact force. Before the bottom wall of the clearance groove 113 begins to apply the punching force to the component to be punched 300, the elastic pressing plate 40 has already pressed the component to be punched 300, preliminarily fixing it. As the bottom wall of the clearance groove 113 continues to move downward, the elastic pressing plate 40 will deform, and then the bottom wall of the clearance groove 113 will apply the required punching force on the component to be punched 300 that has been fixed by the elastic pressing plate 40 to achieve the required deformation or processing. In this way, the accuracy of the stamping and the quality of the stamped product can be guaranteed.

[0089] According to the present application, the stamping portion 11 and the cutting portion 12 are movably connected, and when the cutting portion 12 continues to move relative to the stamping portion 11, the cutting portion 12 can move in the vertical direction. On the one hand, the matching degree of the long strip hole 123 and the connecting bolt 118 can be set to ensure that the cutting portion 12 can move in the vertical direction. On the other hand, a guide component can be set on the stamping portion 11 and the cutting portion 12 to further increase the reliability of the stamping portion 11 and the cutting portion 12 during relative movement.

[0090] In some embodiments, a guide post 115 is provided on one of the punching portion 11 and the cutting portion 12 , and a guide groove 124 is provided on the other, and the guide post 115 cooperates with the guide groove 124 .

[0091] Specifically, if Figures 4 to 9 As shown, a guide column 115 extending in the vertical direction is provided on the main body 111 of the stamping part 11, and a guide groove 124 extending in the vertical direction is provided on the connecting boss 121 of the cutting part 12. The guide column 115 cooperates with the guide groove 124. In this way, when the stamping part 11 and the cutting part 12 move relative to each other, they can move in the vertical direction with the cooperation of the guide components. In this way, the accuracy of cutting can be increased and the yield rate can be improved.

[0092] like Figure 4 、 Figures 9 to 11 As shown, a guide post 115 extending vertically is provided on the main body 111 of the punching portion 11 , and the guide post 115 passes through the buffer member 30 and is connected to the guide groove 124 on the connecting boss 121 of the cutting portion 12 .

[0093] According to the present application, a positioning groove 22 may be added to the lower die assembly 20 to position the component 300 to be punched, so as to limit the lateral movement of the component 300 to be punched, thereby ensuring the stability of the position of the component 300 to be punched and improving the accuracy of the stamping operation.

[0094] In some embodiments, the lower mold assembly 20 further includes a positioning groove 22 disposed on one side of the forming groove 21. The component to be punched 300 can be placed in the positioning groove 22, thereby limiting the lateral movement of the component to be punched 300. As an example, the shape and size of the positioning groove 22 match the component to be punched 300, and the component to be punched 300 can fit tightly in the positioning groove 22, thereby limiting the lateral movement (horizontal movement) of the component to be punched 300.

[0095] In these embodiments, a positioning groove 22 is provided on one side of the forming groove 21 on the lower mold assembly 20, and the positioning groove 22 can accommodate and fix the component to be punched 300, thereby ensuring the stability of the placement of the component to be punched 300. In this way, the bottom wall of the positioning groove 113 can accurately act on the target area of ​​the component to be punched 300, thereby improving the accuracy and consistency of the stamping and reducing the scrap rate and rework rate.

[0096] In some embodiments, a notch 221 is formed on one side of the positioning groove 22, allowing a portion of the punched component 300 to be suspended in the air. The stamping device includes a start / stop button, which is located on the same side of the positioning groove 22 as the notch 221. As an example, the notch 221 is formed on the edge of the positioning groove.

[0097] In these embodiments, by providing a notch 221 on one side of the positioning groove 22, when the device 300 to be punched is placed in the positioning groove 22, its edge portion will be suspended due to the presence of the notch 221, thus facilitating the pick-up and placement of the device 300 to be punched. The start-stop button is arranged at a position on the same side of the positioning groove 22 as the notch 221. Thus, before the stamping operation begins, the operator usually places the device 300 to be punched with one hand, and then simultaneously presses the start-stop button to start the device. This can, to a certain extent, avoid injuries caused by accidental pressing during the cyclic operation of the operator's two-handed operation, thereby improving the safety of the operation. In addition, when an abnormal situation occurs or the stamping operation needs to be stopped urgently, the operator can use the start-stop button again to shut down the stamping device to ensure the safety of personnel and equipment.

[0098] According to the present application, the lower mold assembly 20 also includes a device support seat 90, the molding groove 21 is formed on the upper edge of the device support seat 90, the stamping molding device includes a mounting base 100, and the device support seat 90 is detachably arranged on the mounting base 100.

[0099] like Figure 2 、 Figure 13 、 Figure 14The device support base 90 is formed with a forming groove 21 for supporting the device 300 to be punched, and the forming groove 21 is formed at the upper edge of the device support base 90. Here, the forming groove 21 is intended to ensure that the device 300 to be punched can be deformed in a predetermined manner when subjected to the punching force, thereby achieving the desired forming effect. Its arrangement near the edge can guide and control the deformation of the device 300 to be punched during the punching process.

[0100] In the embodiment of the present application, the mounting base 100 provides a stable support platform for the stamping and forming apparatus, securing and supporting the lower die assembly 20 (including the device support base 90 to be stamped) and other related components. By detachably attaching the device support base 90 to the mounting base 100, device support bases 90 of different shapes and sizes can be easily replaced to accommodate the stamping requirements of different devices to be stamped.

[0101] In these embodiments, by providing a support seat 90 for the device to be punched and detachably arranging it on the mounting base 100, the design of the lower mold assembly 20 becomes more flexible, allowing different types of device support seats 90 to be adjusted according to different stamping requirements, thereby improving the versatility and adaptability of the stamping forming device.

[0102] According to the present application, a guide structure is provided between the upper mold assembly 10 and the lower mold assembly 20. The guide structure ensures that the upper mold assembly 10 and the lower mold assembly 20 are accurately aligned during mold closing, preventing mold misalignment or tilting, thereby ensuring the shape and dimensional accuracy of the target device. In addition, during the stamping process, the guide structure can guide the upper mold assembly 10 to descend and ascend smoothly, preventing the mold from shaking or trembling during stamping, ensuring the stability and safety of the stamping process, and also reducing friction and wear between the molds, thereby extending the service life of the molds.

[0103] In some embodiments, a guide rod 23 is provided on one of the punching portion 11 and the lower die assembly 20 , and a guide hole 117 is provided on the other, and the guide rod 23 cooperates with the guide hole 117 .

[0104] like Figure 2 、 Figure 8 as well as Figure 13 As shown, a guide hole 117 is provided on the main body 111 of the stamping part 11, and a guide rod 23 is formed on the punch component support seat 90 of the lower mold assembly 20. The guide rod 23 can be inserted into the guide hole 117 when the upper mold assembly 10 and the lower mold assembly 20 are closed.

[0105] In these embodiments, when the upper mold assembly 10 is lowered, the guide rods 23 can be smoothly inserted into the guide holes 117, thereby achieving precise alignment and stable movement.

[0106] Although the embodiments of the present invention have been described in detail above, those skilled in the art may make various modifications and variations to the embodiments of the present invention without departing from the spirit and scope of the present invention. However, it should be understood that, in the opinion of those skilled in the art, such modifications and variations will still fall within the spirit and scope of the embodiments of the present invention as defined in the claims.
