Description

Technical Field

[0001] This utility model relates to the field of automated processing equipment technology, specifically to an automatic feeding and unloading stamping machine for material strips and a production line equipped with the automatic feeding and unloading stamping machine for material strips. Background Technology

[0002] In the field of metal stamping, stamping presses, as a high-efficiency forming equipment, are widely used in the production of precision metal products such as automotive parts and electronic components. In traditional stamping processes, the loading and unloading of material strips is generally done manually. That is, the operator manually unrolls the metal coil to form a continuous strip, and then manually positions and feeds the strip step by step into the stamping die station. After the stamping process is completed, the stamped parts also need to be manually removed from the die area.

[0003] However, the above-mentioned operating mode has the following technical drawbacks: First, manual intervention in the working area of ​​the stamping machine poses serious safety hazards. Operators are prone to work-related injuries such as mechanical clamping and mold impacts due to equipment mis-triggering or fatigue operation during feeding, positioning, and part removal. Second, the efficiency of manual loading and unloading is limited by the operator's proficiency, making it difficult to match the cycle time requirements of high-speed stamping equipment, resulting in a decrease in equipment utilization. Third, the accuracy of manual positioning is greatly affected by subjective factors, which can lead to material strip deviation or positioning errors, thereby causing quality problems such as out-of-tolerance product dimensions or even mold damage. In addition, the existing stamping mechanism of the stamping machine lacks monitoring, making it impossible to accurately determine whether a single stamping action has been completed. Summary of the Invention

[0004] In order to solve the above problems, the main purpose of this utility model is to provide an automatic feeding and unloading stamping machine for material strips that can realize automatic loading and unloading, and improve stamping accuracy, production efficiency and reliability.

[0005] Another objective of this invention is to provide a production line equipped with the aforementioned automatic feeding and unloading stamping machine for material strips.

[0006] To achieve the main objective of this utility model, it provides an automatic strip feeding and unloading stamping machine, including a stamping mechanism. The stamping mechanism includes an upper die, a lower die, and a first drive unit. The first drive unit can drive the upper die to move relative to the lower die. The automatic strip feeding and unloading stamping machine further includes an unwinding mechanism, a winding mechanism, a unloading mechanism, a detection mechanism, and a control mechanism. The unwinding mechanism includes an unwinding wheel, and the winding mechanism includes a winding wheel and a second drive unit. The connection between the discharge end of the unwinding mechanism and the inlet end of the winding mechanism is located between the upper die and the lower die. The second drive unit can drive the winding wheel to rotate. The unloading mechanism includes a pusher plate and a third drive unit. The third drive unit can drive the pusher plate to move between the upper die and the lower die, so that the pusher plate cleans the lower die. The detection mechanism is used to detect whether the upper die has moved to the stamping position. The control mechanism is electrically connected to the first drive unit, the second drive unit, the third drive unit, and the detection mechanism.

[0007] Therefore, the coordination of the unwinding and rewinding mechanisms enables automatic unwinding and rewinding of the strip material, eliminating the need for manual feeding and unwinding, greatly improving production efficiency, reducing labor costs, and mitigating problems such as inaccurate feeding that may occur with manual operation. Furthermore, by configuring a blanking mechanism, the stamped parts formed by stamping can be automatically moved from the lower die to a designated position for blanking, eliminating the need for manual blanking and further improving the level of automation, making the entire stamping process smoother. Moreover, with the assembly of the detection mechanism, the stamping mechanism can effectively monitor whether the stamping action has been completed, ensuring that the stamping action is completed correctly and guaranteeing the forming quality and accuracy of the stamped parts.

[0008] In a preferred embodiment, the first drive unit includes a motor, a pulley assembly, a crankshaft, and a connecting rod. The output shaft of the motor is connected to the input pulley of the pulley assembly, the crankshaft is connected to the output pulley of the pulley assembly, and the first end of the connecting rod is connected to the connecting shaft portion of the crankshaft. The upper die includes a guide assembly and a stamping assembly. The guide assembly extends along the stamping direction of the stamping mechanism, the stamping assembly is slidably connected to the guide assembly, and is ball-jointed to the second end of the connecting rod. The first drive unit can drive the stamping assembly to move relative to the lower die through the guide assembly.

[0009] Therefore, by designing the first drive unit, the motor does not need to frequently reverse to control the movement of the upper mold relative to the lower mold, which effectively improves the service life of the first drive unit and also enhances the reliability of its operation.

[0010] A further embodiment includes a detection mechanism comprising a fixed base, a trigger block, a rocker arm, and a sensor. The fixed base has a connecting hole, a first arc-shaped groove, and at least two second arc-shaped grooves concentrically distributed with equal radii. The connecting hole and the first arc-shaped grooves are concentrically distributed. The trigger block has a pressure-bearing part, a first driving part, and a first pin matching the number of second arc-shaped grooves. One first pin is inserted into one second arc-shaped groove. The first end of the rocker arm is rotatably connected to the connecting hole via the second pin. The rocker arm has a third pin inserted into the first arc-shaped groove. The sensor has a sensing rod. A tension spring is provided between the second end of the rocker arm and the sensing rod. A second driving part is provided around the crankshaft. The second driving part can rotate with the crankshaft to contact the pressure-bearing part to drive the trigger block to slide along the second arc-shaped groove, causing the first driving part to drive the rocker arm to rotate around the connecting hole along the first arc-shaped groove, thereby causing the rocker arm to pull the sensing rod to slide.

[0011] It is evident that the above design makes the testing facility easy to install and maintain, and its relatively simple structure and small number of required electronic components make the testing facility more stable and reliable in operation.

[0012] A further embodiment includes a stamping mechanism that also includes a guide rail, a sliding seat, and an adjustment unit. The guide rail extends along the stamping direction, and the sliding seat is slidably connected to the guide rail. The first drive unit, guide assembly, fixed seat, and sensor are all mounted on the sliding seat. The adjustment unit is connected between the guide rail and the sliding seat, and can drive the sliding seat to slide relative to the guide rail.

[0013] It is evident that this design increases the flexibility of the stamping mechanism and allows it to adapt to different processing requirements, thereby enhancing the practicality of the automatic strip feeding and unloading stamping machine.

[0014] Another preferred embodiment is that the unwinding mechanism further includes a fourth drive unit that can drive the unwinding wheel to rotate.

[0015] Therefore, setting a fourth drive unit to drive the unwinding wheel to rotate helps with automatic feeding of the strip, while avoiding excessive tension on the strip, preventing strip breakage and / or deformation due to tension, which could lead to the stamped parts not meeting production requirements in terms of size, thus helping to improve the production accuracy of stamped parts.

[0016] A further embodiment is that the unwinding mechanism also includes a tension roller, a fifth drive unit, and a first guide roller group. The tension roller and the first guide roller group are distributed along the connecting line. Along the unwinding direction of the unwinding wheel, the tension roller is located between the unwinding wheel and the first guide roller group. The fifth drive unit can drive the tension roller to move relative to the first guide roller group on the connecting line. The winding mechanism also includes a second guide roller group, which is distributed on the connecting line.

[0017] Therefore, the cooperation between the tension roller and the fifth drive unit helps to adjust the tension of the strip, so that the strip remains taut but does not deform due to tension (tensioning of the unwinding and take-up rollers), thereby ensuring the dimensional accuracy of the stamped parts formed by stamping. The first guide roller group is used to change the direction of the strip, so that the unwinding roller can better unwind the strip and move it to the second guide roller group. The second guide roller group is also used to change the direction of the strip, so that the strip can be better wound onto the take-up roller. The cooperation between the first guide roller group and the second guide roller group can ensure the positional accuracy of the strip, so that the stamping mechanism can perform precise and reliable stamping processing on the strip.

[0018] Another further embodiment is that the unwinding mechanism also includes a pressure rod and a sixth drive unit. The first end of the pressure rod is provided with a pressure roller, and the sixth drive unit is connected to the second end of the pressure rod. The sixth drive unit can drive the pressure rod to rotate around the second end of the pressure rod, so that the pressure roller moves toward the unwinding roller.

[0019] Therefore, this design helps to control the stability of unwinding and prevents the material strip from becoming loose during the unwinding process.

[0020] Another further embodiment is that the unwinding reel includes a reel body and multiple limiting clamps. The reel body has a mounting shaft and a disc. The disc is arranged around the mounting shaft. The mounting shaft is provided with multiple support plates distributed around itself. The support plates extend along the axial direction of the mounting shaft. The multiple limiting clamps correspond one-to-one with the multiple support plates. The limiting clamps are slidably mounted on the corresponding support plate, and a clamping position is formed between the limiting clamps and the disc.

[0021] It is evident that by designing the unwinding roller, it becomes possible to accommodate strip rolls of different widths, thereby enhancing the practicality and applicability of the automatic strip feeding and unloading punching machine.

[0022] A further proposed solution is to include a material feeding chute in the feeding mechanism, located at the downstream end of the lower die along the feeding direction of the pusher plate.

[0023] Therefore, the feeding chute can accurately guide the stamped parts pushed out by the pusher plate to the designated station for recycling or to participate in the next stage of processing, and has a collection function to prevent the stamped parts from being scattered all over the ground.

[0024] To achieve another objective of this utility model, this utility model provides a production line, which includes the above-mentioned automatic material feeding and unloading stamping machine.

[0025] It is evident that production lines equipped with the aforementioned automatic feeding and unloading stamping machine for material strips have a high degree of automation, high production efficiency, and high quality of stamped parts. Attached Figure Description

[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0033] Example of an automatic feeding and unloading stamping machine for material strips:

[0034] Reference Figure 1 The automatic feeding and unloading stamping machine 100 includes a frame 10, a stamping mechanism 1, a detection mechanism 2, an unwinding mechanism 3, a winding mechanism 4, a feeding mechanism 5, and a control mechanism 6. The stamping mechanism 1, the unwinding mechanism 3, the feeding mechanism 5, and the control mechanism 6 are all mounted on the frame 10. The winding mechanism 4 can be mounted on the frame 10 or located outside the frame 10, i.e., it can be mounted on other external structures. It is understood that, based on the installation inspiration of the winding mechanism 4, the unwinding mechanism 4 can also be located outside the frame 10 (i.e., mounted on other external structures).

[0035] Combination Figure 2 The stamping mechanism 1 includes an upper die 11, a lower die 12, and a first drive unit 13. The upper die 11 and the lower die 12 are distributed along the height direction of the frame 10, and the lower die 12 is mounted on the frame 10. The first drive unit 13 is used to drive the upper die 11 to move relative to the lower die 12, so that the upper die 11 moves to the lower die 12 to cooperate with the lower die 12 to stamp the strip material, thereby forming a stamped part; or to drive the upper die 11 to move away from the lower die 12 to release the formed stamped part, and enable the unloading mechanism 5 to clean the stamped part from the lower die 12, so that the stamped part can be collected or transferred to the next level processing equipment for subsequent processing.

[0036] In this embodiment, the stamping mechanism 1 further includes a guide rail frame 14, a sliding seat 15, and an adjustment unit 16. The guide rail frame 14 is mounted on the frame 10 and extends along the stamping direction of the stamping mechanism 1 (which is parallel to the height direction of the frame 10). The sliding seat 15 is slidably connected to the guide rail frame 14, allowing the sliding seat 15 to move relative to the lower die 12 in the stamping direction via the guide rail frame 14, ensuring the smoothness of the movement of the sliding seat 15.

[0037] Both the upper die 11 and the first drive unit 13 are mounted on the sliding seat 15 to move with the sliding seat 15. The upper die 11 includes a guide assembly 111 and a stamping assembly 112. The guide assembly 111 extends along the stamping direction of the stamping mechanism 1 and is mounted on the sliding seat 15. The stamping assembly 112 is slidably connected to the guide assembly 111, so that the stamping assembly 112 can move smoothly relative to the lower die 12 in the stamping direction through the guide assembly 111, thereby ensuring the forming accuracy and forming quality of the stamped part.

[0038] Combination Figure 3 The first drive unit 13 includes a motor 131, a pulley assembly 132, a crankshaft 133, and a connecting rod 134. The motor 131 is mounted on a sliding seat 15 and electrically connected to the control mechanism 6. The crankshaft 133 is rotatably mounted on the sliding seat 15 around its own axis of rotation. The input pulley of the pulley assembly 132 is connected to the output shaft of the motor 131, and the output pulley 1321 of the pulley assembly 132 is connected to the crankshaft 133. The diameter of the input pulley is smaller than the diameter of the output pulley 1321, so that the motor 131 drives the rotation of the crankshaft 133 by reducing speed through the pulley assembly 132. The first end of the connecting rod 134 is connected to the connecting shaft portion 1331 of the crankshaft 133, and the second end of the connecting rod 134 is ball-jointed to the stamping assembly 112 of the upper die 11, so that the first drive unit 13 can drive the stamping assembly 112 to move relative to the lower die 12 in the stamping direction through the guide assembly 111.

[0039] With the coordinated action of crankshaft 133, connecting rod 134, guide assembly 111, etc., the linear reciprocating movement of stamping assembly 112 can be achieved by the unidirectional continuous rotation of motor 131, thus eliminating the need for frequent starting and stopping of motor 131 and frequent forward and reverse rotation of motor 131. This helps extend the service life of motor 131 and ensures smooth and efficient transmission and stamping accuracy. In addition, since the drive mechanism of the first drive unit 13 is mainly mechanical with almost no electrical drive structure, the maintenance and repair of stamping mechanism 1 is more convenient and less costly. Furthermore, by adjusting the speed of the motor 131, the transmission ratio of the pulley assembly 132, and the parameters of the crankshaft 133, the stamping speed, frequency, and stroke parameters can be easily changed to adapt to the stamping requirements of workpieces with different materials, thicknesses, and shapes, thus improving the adaptability and flexibility of the automatic strip feeding and unloading stamping machine for different stamping processes. Moreover, by rationally designing the dimensions, shape, and motion parameters of the crankshaft 133 and connecting rod 134, various forms of stamping actions can be realized, such as single stamping, continuous stamping, and step-by-step stamping, meeting the production process requirements of different products and broadening the application range of the automatic strip feeding and unloading stamping machine 100.

[0040] See also Figure 2The adjusting unit 16 is connected between the guide rail frame 14 and the sliding seat 15, and is used to drive the sliding seat 15 to slide relative to the guide rail frame 14. This design increases the flexibility of the stamping mechanism 1 and allows it to adapt to different processing requirements, improving the practicality of the automatic strip feeding and unloading stamping machine 100. For example, the overall position of the stamping mechanism 1 can be flexibly adjusted according to different stamping requirements. For instance, when processing workpieces of different thicknesses or shapes, the distance between the upper die 11 and the lower die 12, the stamping stroke, and other parameters can be adjusted by adjusting the position of the sliding seat 15, thereby adapting to various stamping process requirements and expanding the applicability of the automatic strip feeding and unloading stamping machine. In addition, when it is necessary to change the mold (such as the upper die 11 and / or the lower die 12), the position of the sliding seat 15 can be quickly adjusted by the adjusting unit 16 to adapt to the size and installation requirements of the new mold, reducing mold change time, improving the production efficiency of the equipment, enabling the stamping machine to cope with the production tasks of different products more efficiently, and enhancing the flexibility and market adaptability of the equipment. Furthermore, this design facilitates the installation, debugging, and maintenance of the stamping mechanism 1, reducing maintenance difficulty and time, improving equipment maintainability, and reducing downtime, thereby lowering production costs. In this embodiment, the adjustment unit 16 includes a screw 161 and an adjustment handwheel 162. The screw 161 is parallel to the stamping direction of the stamping mechanism 1 and is rotatably connected to the guide rail frame 14. The sliding seat 15 is threadedly connected to the screw 161. The adjustment handwheel 162 is connected to the screw 161 and is used to drive the screw 161 to rotate, thereby causing the screw 161 to drive the sliding seat 15 to slide relative to the guide rail frame 14.

[0041] The detection mechanism 2 is mainly used to detect whether the upper die 11 has moved to the stamping position, thereby monitoring whether the stamping mechanism 1 has completed the stamping action and ensuring that the stamping action of the stamping mechanism 1 is completed in place, thus guaranteeing the forming quality and accuracy of the stamped parts. In addition, the detection mechanism 2 can also act as a counter, allowing the control mechanism 6 to promptly determine whether the strip roll has been unwound, thus reminding the user to replace it with a new strip roll. Combined with... Figure 4 The detection mechanism 2 includes a fixed base 21, a trigger block 22, a swing arm 23, a sensor 24, and a tension spring 25. The fixed base 21 and the sensor 24 are both mounted on the sliding seat 15 of the stamping mechanism 1, so that the detection mechanism 2 moves synchronously with the stamping mechanism 1 except for the lower die 12, thereby ensuring the accuracy of the detection.

[0042] The mounting base 21 is provided with a connecting hole 211, a first arc-shaped groove 212, and a second arc-shaped groove 213. The connecting hole 211 is located between the first arc-shaped groove 212 and the crankshaft 133, and the connecting hole 211 and the first arc-shaped groove 212 are concentrically distributed, that is, the connecting hole 211 can be regarded as the center of the first arc-shaped groove 212. Preferably, there are two second arc-shaped grooves 213, which are concentrically distributed and have the same radius. The second arc-shaped grooves 213 are located between the connecting hole 211 and the crankshaft 133, and the center of the second arc-shaped groove 213 is located between the crankshaft 133 and the second arc-shaped groove 213.

[0043] The actuating block 22 is provided with a pressure-receiving part 221, a first driving part 222, and a first pin 223. In the height direction of the frame 10, the pressure-receiving part 221 is preferably located at the top of the actuating block 22, and the first driving part 222 is preferably located at the bottom of the actuating block 22. The number of first pins 223 is equal to the number of second arc-shaped grooves 213, and one first pin 223 is inserted into one second arc-shaped groove 213, so that the actuating block 22 can slide along the second arc-shaped groove 213.

[0044] The first end of the swing rod 23 is rotatably connected to the connecting hole 211 via the second pin 231, and the swing rod 23 is provided with a third pin 232, which is inserted into the first arc groove 212, so that the swing rod 23 can swing around the second pin 231 along the first arc groove 212.

[0045] Sensor 24 is electrically connected to control mechanism 6. Sensor 24 has a sensing rod 241, which can slide relative to the body of sensor 24. Tension spring 25 is connected between one end of sensing rod 241 and the second end of swing rod 23, so that when swing rod 23 swings away from sensor 24, tension spring 25 can pull sensing rod 241 to move relative to the body of sensor 24. When sensor 24 drives sensing rod 241 to reset, sensing rod 241 can pull swing rod 23 to reset via tension spring 25.

[0046] Depend on Figure 2 and Figure 3 It can be seen that the crankshaft 133 is provided with a second driving part 1332 around its periphery. The second driving part 1332 can rotate with the crankshaft 133 to contact the pressure part 221 and drive the touch block 22 to slide along the second arc groove 213 and the direction R1. This causes the first driving part 222 of the touch block 22 to drive the rocker arm 23 to rotate around the connecting hole 211 along the first arc groove 212 and the direction R2, thereby causing the rocker arm 23 to pull the sensing rod 241 to slide.

[0047] The design of the detection mechanism 2 facilitates installation and maintenance, and its relatively simple structure and low requirement for electronic components make its operation more stable and reliable. Furthermore, this design enables the detection mechanism 2 to monitor the rotational state of the crankshaft 133 in real time and provide timely feedback to the control mechanism 6. This allows the control mechanism 6 to understand the working status of the stamping machine in real time, such as stamping position and stamping frequency, thereby achieving precise control and monitoring of the stamping process and ensuring the normal operation of the stamping machine and product quality.

[0048] The stamping mechanism 1 is located between the unwinding mechanism 3 and the winding mechanism 4, and is combined with Figure 5 The unwinding mechanism 3 includes a first mounting base 30, an unwinding wheel 31, a fourth drive unit 32, a tensioning roller 33, a fifth drive unit 34, a first guide roller group 35, a pressure rod 36, and a sixth drive unit 37; the first mounting base 30 is mounted on the frame 10.

[0049] The unwinding wheel 31 is rotatably mounted on the first mounting base 30 around its own rotation axis. In this embodiment, the unwinding wheel 31 includes a wheel body 311 and a limiting clamp 312. The wheel body 311 has a mounting shaft portion 3111 and a disc portion 3112. The mounting shaft portion 3111 is used to mount the material strip roll, and the disc portion 3112 is arranged around the mounting shaft portion 3111. The mounting shaft portion 3111 is provided with multiple support plates 31111, which are distributed around the mounting shaft portion 3111 and extend along the axial direction of the mounting shaft portion 3111. The number of limiting clamps 312 is equal to the number of support plates 31111. Multiple limiting clamps 312 correspond one-to-one with multiple support plates 31111, ensuring that one limiting clamp 312 is installed on each support plate 31111. The limiting clamp 312 is slidably connected to the support plate 31111, forming a clamping position between the limiting clamp 312 and the disc 3112 to clamp the strip roll and prevent it from moving axially along the mounting shaft 3111. Furthermore, the limiting clamp 312 and the support plate 31111 are preferably connected by a snap-fit ​​connection, making the assembly and disassembly of the limiting clamp 312 and support plate 31111 simpler and easier to operate. This also makes adjusting the position of the limiting clamp 312 more convenient, allowing the unwinding roller 31 to accommodate strip rolls of different widths, improving the practicality and applicability of the automatic strip feeding and unloading punch press 100, and making strip roll replacement more convenient.

[0050] The fourth drive unit 32 is mounted on the first mounting base 30 and electrically connected to the control mechanism 6. The fourth drive unit 32 is used to drive the unwinding wheel 31 to rotate; preferably, the fourth drive unit 32 is a motor. The fourth drive unit 32 can precisely control the rotational speed of the unwinding wheel 31, making it precisely match the overall operating speed of the automatic strip feeding and unloading stamping machine and the winding speed of the winding mechanism 4. During the stamping process, different stamping frequencies and process requirements require the strip to be supplied at different speeds. The fourth drive unit 32 can flexibly adjust the unwinding speed to ensure that the strip is always delivered to the stamping position at a suitable speed, ensuring the continuity and stability of the production process, avoiding insufficient or excessive strip supply, and improving production efficiency and product quality. Furthermore, thanks to the assistance of the fourth drive unit 32, when the winding mechanism 4 winds up the strip after stamping, the strip will not break due to excessive difference between the unwinding force and the winding force, or the dimensions of the stamped parts formed by the stamping will not fail to meet production requirements due to tensile deformation. This helps to improve the production accuracy of the stamped parts, and at the same time, it can keep the strip taut and prevent it from loosening, ensuring the dimensional accuracy and forming quality of the stamped parts formed by the stamping.

[0051] The fifth drive unit 34 is mounted on the first mounting base 30, and the tension roller 33 is mounted on the drive end of the fifth drive unit 34. The fifth drive unit 34 is preferably a cylinder or an electric push rod, and is controlled by the control mechanism 6. The first guide roller group 35 is mounted on the first mounting base 30. The tension roller 33 and the first guide roller group 35 are distributed along the line connecting the discharge end of the unwinding mechanism 3 and the feed end of the winding mechanism 4, which is located between the upper die 11 and the lower die 12 of the stamping mechanism 1. Along the unwinding direction of the unwinding wheel 31, the tension roller 33 is located between the unwinding wheel 31 and the first guide roller group 35. The fifth drive unit 34 drives the tension roller 33 to move relative to the first guide roller group 35 along the connecting line. The cooperation between the tension roller 33 and the fifth drive unit 34 helps to adjust the tension of the strip so that the strip remains taut but does not deform due to tension (tensioning of the unwinding roller 31 and the take-up roller 41), thereby ensuring the dimensional accuracy of the stamped parts formed by stamping; while the first guide roller group 35 is used to change the direction of the strip so that the unwinding roller 31 can better unwind the strip roll and move it to the second guide roller group 43.

[0052] The first end of the pressure rod 36 is provided with a pressure roller 361, and the second end of the pressure rod 36 is rotatably mounted on the first mounting base 30. This allows the pressure roller 361 on the pressure rod 36 to rotate towards the mounting shaft 3111 of the unwinding wheel 31 via the second end of the pressure rod 36, thereby appropriately pressing the strip roll on the unwinding wheel 31 to prevent the strip roll from becoming loose or slipping, thus ensuring that the unwound strip remains taut and achieving uniform unwinding. The sixth drive unit 37 is connected between the second end of the pressure rod 36 and the first mounting base 30. The sixth drive unit 37 is used to drive the pressure rod 36 to rotate around the second end of the pressure rod 36, causing the pressure roller 361 to rotate to the position of the strip roll on the unwinding wheel 31 and appropriately press the strip roll. In this embodiment, the sixth drive unit 37 is a cylinder or an electric push rod, and is controlled by the control mechanism 6. Of course, in some embodiments, the sixth drive unit 37 can also be a spring, such as a torsion spring, tension spring, or compression spring. When the sixth drive unit 37 is a spring, the connection between the sixth drive unit 37, the pressure rod 36, and the first mounting base 30 is a conventional technical method, and therefore will not be described in detail here. The sixth drive unit 37 ensures that the pressure roller 361 on the pressure rod 36 is stable and presses it firmly onto the strip roll with appropriate pressure, thereby preventing the strip roll from becoming loose while avoiding damage to the strip by the pressure roller 361.

[0053] Combination Figure 6 The winding mechanism 4 includes a second mounting base 40, a winding wheel 41, a second drive unit 42, and a second guide roller group 43. In this embodiment, the second mounting base 40 is located outside the frame 10, but it is understood that in other embodiments, the second mounting base 40 may be located on the frame 10. The winding wheel 41 is rotatably mounted on the second mounting base 40 about its own rotation axis. The second drive unit 42 is mounted on the second mounting base 40 and electrically connected to the control mechanism 6. The second drive unit 42 is preferably a motor, and the output shaft of the second drive unit 42 is connected to the winding wheel 41 to drive the winding wheel 41 to rotate and wind the material strip. The above-mentioned connection is formed between the second guide roller group 43 (i.e., the feed end of the winding mechanism 4) and the first guide roller group 35 (i.e., the discharge end of the unwinding mechanism 3). The second guide roller group 43 is used to change the direction of the strip so that the strip can be better wound and recycled onto the winding wheel 41. By setting the first guide roller group 35 and the second guide roller group 43, the cooperation between the two can ensure the positional accuracy of the strip, so that the stamping mechanism 1 can perform precise and reliable stamping processing on the strip. At the same time, the unwinding wheel 31 can better unwind the strip and the winding wheel 41 can better wind the strip, and ensure that the strip is always kept taut, so as to ensure the dimensional accuracy and processing quality of the stamped parts formed by stamping.

[0054] Reference Figure 1 and Figure 2The unloading mechanism 5 includes a pusher plate 51, a third drive unit 52, and an unloading groove 53. The third drive unit 52 is mounted on the frame 10. The third drive unit 52 is preferably a cylinder or an electric push rod, and is controlled by the control mechanism 6. The pusher plate 51 is connected to the drive end of the third drive unit 52, so that the third drive unit 52 can drive the pusher plate 51 to move between the upper die 11 and the lower die 12. Along the pushing direction of the pusher plate 51, the unloading groove 53 is located at the downstream end of the lower die 12, so that the pusher plate 51 cleans the stamped parts stamped on the lower die 12, so that the stamped parts fall into the unloading groove 53, and are recycled to the set recycling bin or the next stage equipment for processing in the next stage.

[0055] In summary, the cooperation of the unwinding mechanism 3 and the winding mechanism 4 enables automatic unwinding and winding of the strip material, eliminating the need for manual feeding and unwinding, greatly improving production efficiency, reducing labor costs, and mitigating problems such as inaccurate feeding that may occur due to manual operation. Furthermore, by configuring the unloading mechanism 5, the stamped parts formed by stamping can be automatically moved from the lower die 12 to a designated position for unloading, eliminating the need for manual unloading and further improving the level of automation, making the entire stamping process smoother. Moreover, with the assembly of the detection mechanism 2, it is possible to effectively monitor whether the stamping mechanism 1 has completed its stamping action, ensuring that the stamping action of the stamping mechanism 1 is completed in place, and guaranteeing the forming quality and accuracy of the stamped parts.
