[0001] This utility model relates to a material support mechanism, specifically a material support mechanism built into a stamping die, belonging to the technical field of terminal stamping equipment. Background Technology

[0002] Terminals are components that connect a battery to an external conductor. In electrical engineering, terminals often refer to wiring terminals, also called wiring terminals. Types include single-hole, double-hole, plug, hook, etc. In terms of materials, they include silver-plated copper, zinc-plated copper, copper, aluminum, iron, etc. Their main function is to transmit electrical signals or conduct electricity.

[0003] Chinese Patent Publication No. CN222817775U discloses a continuous stamping die for terminals, including a base plate, a continuous stamping mechanism, and a changing mechanism. Vertical plates are mounted on the upper ends of both sides of the base plate, and a top plate is mounted on the upper end of the vertical plates. Continuous stamping mechanisms for efficiently stamping terminal raw materials are provided on the upper sides of both the center of the top plate and the center of the base plate. When different types of terminals need to be stamped, this invention pulls the clamping plate outwards, causing it to move in and out of the slot, which in turn moves the side plate in and out of the side slot, compressing the hydraulic rod and the second spring, thus generating potential energy in the second spring.

[0004] However, the inventor of the above device believes that there are certain defects. During the continuous stamping process of the material strip, the terminal material strip is easily stuck in the stamping die, which prevents the material strip from being transported normally and affects the subsequent stamping process. Therefore, this utility model provides a material support mechanism built into the stamping die. Utility Model Content

[0006] The purpose of this utility model is to provide a built-in material support mechanism for stamping dies to solve the above-mentioned problems, thereby addressing the issue in the prior art where terminal strips are easily stuck inside the stamping die, causing the strips to be unable to be transported normally and affecting subsequent stamping processes.

[0007] (II) Technical Solution

[0008] This utility model is achieved through the following technical solution: a built-in material support mechanism for a stamping die, including a fixed base, a mounting seat fixedly connected to the top of the fixed base, a lower die base fixedly connected to the top of the mounting seat, a punch opening on the lower die base, a lifting plate directly above the lower die base, a stamping head adapted to the punch opening fixedly connected to the bottom of the lifting plate, a push rod slidably connected to the bottom of the lower die base, one end of the push rod extending to the top of the lower die base, a rotating rod rotatably connected inside the mounting seat, a top plate and a connecting block fixedly connected to both ends of the rotating rod respectively, an extrusion rod fixedly connected to both ends of the lifting plate, the extrusion rod being located directly above the connecting block, a connecting plate fixedly connected to the bottom of the push rod, and the top plate being located directly below the connecting plate.

[0009] Preferably, the push rod is located around the punch, and the connecting plate and the inner top wall of the lower die base are connected by a first spring. The first spring is sleeved on the push rod. When the bottom of the connecting plate is subjected to force, the push rod is driven to quickly descend and reset through the rebound of the connecting plate.

[0010] Preferably, a torsion spring is sleeved on one end of the rotating rod, one end of the torsion spring is fixedly connected to the connecting block, and the other end of the torsion spring is fixedly connected to the mounting base. Under the action of the torsion spring, the rotating rod can quickly rotate and reset when it is not under force.

[0011] Preferably, two limiting plates are installed on the top of the lower die base, and the punch is located between the two limiting plates. The two limiting plates are used to limit the material strip passing through the lower die base.

[0012] Preferably, the two ends of the limiting plate are detachably connected to the top of the lower mold base by bolts. The lower mold base is provided with screw holes that are compatible with the bolts. The distance between the two limiting plates is adjusted by the bolts and screw holes.

[0013] Preferably, a receiving hopper is rotatably connected inside the mounting base. The receiving hopper is located directly below the punch. A through groove is provided on one side of the mounting base. One end of the receiving hopper extends to the outside of the mounting base through the through groove. The receiving hopper is used to collect the stamped sheet.

[0014] Preferably, a receiving box is placed on top of the fixed base. The receiving box is located at the inclined end of the receiving hopper. The top plate and the receiving hopper are connected by a pull rope. The receiving box collects the material that slides out of the receiving hopper and drives the receiving hopper to swing under the action of the pull rope.

[0015] Preferably, a fixed frame is fixedly connected to the top of the fixed base, a connecting slide rod is slidably connected to the fixed frame, the lifting plate is fixedly connected to the bottom of the connecting slide rod, a hydraulic cylinder is fixedly connected to the top of the fixed frame, and the telescopic end of the hydraulic cylinder is fixedly connected to the top of the lifting plate. The lifting plate is raised and lowered by activating the hydraulic cylinder, which drives the stamping head to perform stamping processing.

[0016] This utility model provides a built-in material support mechanism for stamping dies, which has the following beneficial effects:

[0017] 1. This device conveys the strip to the lower die base, and controls the lowering of the lifting plate to stamp the strip under the action of the stamping head and punch. After stamping, the lifting plate rises and drives the rotating rod to rotate under the action of the pushing connecting block of the extrusion rod. This causes the top plate at the other end of the rotating rod to push the connecting plate to rise and slide, so that the push rod pushes the strip to prevent the strip from getting stuck in the stamping die and affecting the subsequent continuous stamping process.

[0018] 2. Under the action of the extrusion rod, rotating rod, top plate, connecting block and torsion spring, the device pushes the connecting block to swing downward during the descent of the stamping head, so it will not push the push rod to rise. The stamping head rises once each time it descends, pushing the push rod to slide upward once, thus completing the continuous pushing of material during the continuous stamping process.

[0019] 3. The device uses a collection hopper to push and collect the material pieces. Under the action of the connecting rope, the collection hopper swings around the rotating shaft, thereby accelerating the sliding of the material pieces on the collection hopper, and then collecting them through the collection box.

Detailed Implementation

[0027] This utility model embodiment provides a built-in material support mechanism for a stamping die.

[0028] Example 1:

[0029] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A stamping die built-in material support mechanism includes a fixed base 1, a mounting base 2 fixedly connected to the top of the fixed base 1, a lower die base 3 fixedly connected to the top of the mounting base 2, a punch 31 opened on the lower die base 3, a lifting plate 92 provided directly above the lower die base 3, and a punching head 93 adapted to the punch 31 fixedly connected to the bottom of the lifting plate 92. When the strip material is placed on the lower die base 3, the lifting plate 92 is driven to descend, and the punching head 93 punches the strip material under the action of the punch 31. The residual material falls into the interior of the mounting base 2 through the punch 31.

[0030] Please refer to it again. Figure 1 and Figure 3 A fixed frame 9 is fixedly connected to the top of the fixed base 1. A connecting slide rod 91 is slidably connected to the fixed frame 9. A lifting plate 92 is fixedly connected to the bottom of the connecting slide rod 91. A hydraulic cylinder 11 is fixedly connected to the top of the fixed frame 9. The telescopic end of the hydraulic cylinder 11 is fixedly connected to the top of the lifting plate 92. A second spring is sleeved on the connecting slide rod 91. The lifting plate 92 is pushed to move up and down by activating the hydraulic cylinder 11. The stability of the connecting slide rod 91 during the lifting process is increased under the action of the connecting slide rod 91.

[0031] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 Two limiting plates 6 are installed on the top of the lower die base 3. The punch 31 is located between the two limiting plates 6. The two ends of the limiting plates 6 are detachably connected to the top of the lower die base 3 by bolts. The lower die base 3 is provided with screw holes that are compatible with the bolts. The two limiting plates 6 are used to limit the two sides of the strip. The distance between the two limiting plates 6 is adjusted by the bolts and screw holes.

[0032] Example 2:

[0033] Please refer to it again. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A push rod 41 is slidably connected to the bottom of the lower mold base 3. One end of the push rod 41 extends to the top of the lower mold base 3. The push rod 41 is located around the punch 31. A connecting plate 43 is fixedly connected to the bottom of the push rod 41. Under normal conditions, the top surface of the push rod 41 is lower than the top surface of the lower mold base 3. The connecting plate 43 and the inner top wall of the lower mold base 3 are connected by a first spring 42. The first spring 42 is sleeved on the push rod 41. Under the action of the first spring 42, the connecting plate 43 is connected to the lower mold base 3, so that the push rod 41 slides at the bottom of the lower mold base 3.

[0034] Please refer to it again. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The mounting base 2 has a rotating rod 5 rotatably connected inside. A support seat for rotating the rotating rod 5 is fixed to the inner wall of the mounting base 2. A top plate 51 and a connecting block 52 are fixedly connected to both ends of the rotating rod 5, respectively. A pressing rod 10 is fixedly connected to both ends of the lifting plate 92. The pressing rod 10 is L-shaped and positioned directly above the connecting block 52. When the lifting plate 92 descends, it pushes one end of the pressing rod 10 to press the connecting block 52, thereby driving the rotating rod 5 to rotate. Similarly, when the lifting plate 92 rises, it causes the connecting block 52 to flip upwards. The top plate 51 is located directly below the connecting plate 43. Under the action of the rotating rod 5, when the connecting block 52 flips upward, it drives the top plate 51 to flip upward as well. One end of the top plate 51 pushes the connecting plate 43 to rise. One end of the rotating rod 5 is fitted with a torsion spring 53. One end of the torsion spring 53 is fixedly connected to the connecting block 52, and the other end of the torsion spring 53 is fixedly connected to the mounting base 2. When one end of the connecting block 52 is not under force, the top plate 51 is quickly rotated and reset by the rebound of the torsion spring 53.

[0035] Example 3:

[0036] Please refer to it again. Figure 1 , Figure 2 , Figure 4 and Figure 5The mounting base 2 is rotatably connected to a receiving hopper 7, which is located directly below the punch 31. A through groove is provided on one side of the mounting base 2, and one end of the receiving hopper 7 extends to the outside of the mounting base 2 through the through groove. A receiving box 8 is placed on the top of the fixed base 1, which is located at the inclined end of the receiving hopper 7. The top plate 51 and the receiving hopper 7 are connected by a pull rope. The receiving hopper 7 collects the residual material falling from the punch 31. Under the action of the connecting rope, the top plate 51 swings, pulling the receiving hopper 7 to swing, realizing a small amplitude shaking of the receiving hopper 7, accelerating the material on the receiving hopper 7 to slide down, and the receiving box 8 collects the residual material.

[0037] Working principle: The feeding mechanism feeds the strip onto the lower die base 3. Two limiting plates 6 limit the strip to the left and right. The feeding mechanism drives the strip to move. The hydraulic cylinder 11 is activated to push the lifting plate 92 down. The punching head 93 at the bottom of the lifting plate 92 punches holes in the strip. The residual material falls through the punch 31 into the receiving hopper 7 inside the mounting base 2 for collection. When the punching head 93 punches holes, it drives the lifting plate 92 to rise, causing one end of the extrusion rod 10 to press and push one end of the connecting block 52 upward. The rotating rod 5 causes the other end of the top plate 51 to flip upward inside the fixed base 1, pushing the bottom of the connecting plate 43 to rise. This causes the push rod 41 to slide and push the material strip attached to the lower die base 3, facilitating the normal transport of the material strip and the next stamping process. Under the action of the connecting rope, the top plate 51 swings, pulling the receiving hopper 7 to swing, causing the receiving hopper 7 to shake slightly and accelerate the material from the receiving hopper 7 to slide down. The remaining material is then collected by the receiving box 8.
