[0002] Reinforcing strips are products used to enhance the rigidity and stability of materials. They play a crucial role, especially in the processing of FPCs (flexible printed circuit boards). To ensure that the reinforcing strips meet specific application requirements, stamping is a key step that ensures they meet the specific shape, size, and performance requirements of reinforcing strips in different application scenarios.

[0003] Depending on the application environment, reinforcing sheets are not limited to direct pasting. They often require flanging to process three-dimensional parts with special spatial shapes and good rigidity. During the manufacturing and forming process, stamping is needed to obtain the required shape and structure. In the existing technology, when the stamping device flanging and stamping the reinforcing sheet strip, part of the structure after flanging and stamping will form a clamp on the punch due to elastic deformation, resulting in difficulty in demolding.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The stamping device for the reinforcing strip uses a demolding mechanism to set the punch as a movable part within the demolding mechanism. A servo motor drives the control component to move left and right, thereby controlling the position of the punch. When the punch rises, its bottom structure will create a gap due to dissociation, giving the bottom end of the punch the ability to bend, and thus pull it out from the flange of the strip in the clamp, achieving the demolding effect and improving the convenience of demolding during the flange stamping of the stamping device.

[0016] 2. The stamping device for the reinforcing strip uses lifting frames at both ends of the lower die. During the stamping process, the lifting frames control the height of the strip body. As the upper die presses down, the strip body is placed flat on the stamping point. After the stamping is completed, the lifting frames lift the strip body to a certain height as it is demolded, so that the strip body automatically leaves the die groove and begins the next round of stamping and flanging. There is no need to manually lift the body to demold. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-7A stamping device for reinforcing sheet strip includes: a base 1 and a top frame 3, the base 1 and the top frame 3 are installed together by a guide rod 14, an upper mold 5 is slidably arranged on the guide rod 14, a demolding mechanism 6 is installed on the upper mold 5, a hydraulic cylinder 4 is installed on the top frame 3, the output shaft of the hydraulic cylinder 4 passes through the top frame 3 and is installed on the demolding mechanism 6, a lower mold 2 is installed on the base 1, and lifting frames 9 are installed on both sides of the lower mold 2;

[0027] The demolding mechanism 6 has a control element 11 and a punch 10 slidingly arranged inside. A servo motor 8 is installed on the side of the demolding mechanism 6. A mold groove 12 is opened at the center of the top of the lower mold 2, and the mold groove 12 is located directly below the punch 10.

[0028] The lower die 2 and the upper die 5 both have a stamping platform formed by outward protrusion at the center of their stamping contact surfaces. A strip body 7 is provided between the stamping platforms of the lower die 2 and the upper die 5. When the lower die 2 and the upper die 5 are in contact, the stamping platform fixes the edge of the stamping range of the strip body 7, making the folding marks that appear during stamping more uniform.

[0029] The lifting frame 9 includes a frame base 91, a lifting rod 92 is slidably arranged inside the frame base 91, a lifting seat 93 is installed on the top of the lifting rod 92, a limit frame 94 is installed on the top of the lifting seat 93, and a flange groove 95 is opened on the lifting seat 93. After the material strip body 7 is flanged and stamped, the flanged part can be directly slid out through the flange groove 95, and then the stamping of the next section of the material strip body 7 can begin.

[0030] The lifting frame 9 also includes a receiving cavity 96 opened inside the frame base 91. The lifting rod 92 passes through the receiving cavity 96 and a spring 97 is sleeved on its surface. A limiting ring 98 is sleeved on the surface of the lifting rod 92. The limiting ring 98 is located on top of the spring 97 and slides against the inner wall of the receiving cavity 96. By setting the spring 97 and the limiting ring 98, the lifting rod 92 is given the ability to spring upward, so that when the lifting frame 9 is stamping, it can press down the upper mold 5 to place the strip body 7 flat on the stamping surface. After the stamping is completed, the stamped flange is ejected from the mold groove 12.

[0031] The demolding mechanism 6 includes a demolding shell 61, with a mold cavity 62 inside the demolding shell 61. The punch 10 is slidably disposed in the mold cavity 62. T-slots 64 are provided on both sides of the mold cavity 62. The control member 11 is slidably disposed in the T-slots 64. A frame 65 is installed on both sides of the demolding shell 61. A servo motor 8 is installed on the frame 65 located on one side of the demolding shell 61. A rotating groove 63 for connecting the upper structure of the punch 10 is provided on the inner wall of the mold cavity 62 near the bottom. The mold cavity 62 and T-slots 64 provided in the demolding shell 61 limit the sliding direction of the punch 10 and the control member 11 respectively. At the same time, when pressing down, the connection between the control member 11 and the punch 10 can provide sufficient support force for the punch 10.

[0032] Among them, a lead screw 13 is rotatably mounted on the frame 65 located on both sides of the demolding shell 61 via bearings. One end of the lead screw 13 is mounted on the output shaft of the servo motor 8. The control element 11 is threaded onto the surface of the lead screw 13. The servo motor 8 drives the lead screw 13 to rotate, thereby controlling the movement position of the control element 11.

[0033] The control member 11 has an I-shaped structure on its side, which is larger at the top and smaller at the bottom. The strip structure below the control member 11 is set at an angle. The punch 10 is slidably set on the angled strip structure below the control member 11. The I-shaped structure design gives the control member 11 a stable shape. When the punch 10 is stamping, the control member 11 can serve as a stable fulcrum at the top of the punch 10. At the same time, when the control member 11 moves, the height of the punch 10 can change with the movement of the control member 11, and then demolding can be performed.

[0034] The punch 10 includes a mold body 101. The top of the mold body 101 has a sliding groove 102 that slides with the control member 11. A wedge block 103 is integrally formed at the bottom of the mold body 101. The sides of the wedge block 103 are sloped. A module 105 overlaps the sloped surface of the wedge block 103. A transition seat 107, connected to the upper structure of the demolding mechanism 6, is provided on the side of the module 105 near the top. The middle of the wedge block 103 protrudes outward to form a conical positioning cone 104. The sides of the module 105... A positioning groove 106 is provided to match the positioning cone 104. The punch 10 is set as a combined structure. By pressing down the die body 101, the wedge block 103 is wedged into the two group modules 105 and cooperates with the hole through the upper die 5 to form a stable structure. After the stamping is completed, the gap between the two group modules 105 is exposed by the upward ability of the die body 101, so that the two group modules 105 can move to a certain extent and directly detach from the flange of the clamp.

[0035] The working principle is as follows: When stamping the strip body 7, the lifting frame 9 is used to support the strip body 7 and move the stamping point of the strip body 7 to the center of the lower mold 2. Then, the hydraulic cylinder 4 is controlled to press down the upper mold 5. During the pressing process, the upper mold 5 presses down the lifting frame 9 at the same time, so that the height of both ends of the strip body 7 is level with the stamping point. After the stamping is completed, the upper mold 5 rises one distance so that the strip body 7 is flanged and disengaged from the mold groove 12. Then, the servo motor 8 is started to drive the lead screw 13 to rotate and control the position control component 11 to move, so that the punch 10 is pulled upward. As the upper mold 5 continues to rise, under the restriction of the lifting frame 9, the flange on the punch 10 is disengaged, and the demolding is completed.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
