Description

Technical Field

[0001] The present invention relates to the technical field of bending dies, in particular to a continuous stamping and bending die for a stamping strip. Background Art

[0002] The continuous stamping and bending die for stamping strips is suitable for large-scale, high-efficiency metal product production scenarios, such as batch manufacturing of electronic equipment casings (such as mobile phone middle frames, computer heat sinks), automotive parts (such as door hinges, seat brackets), and home appliance hardware (such as refrigerator drawer rails, air-conditioning grilles). It is especially suitable for scenarios with high requirements for product precision and strength and continuous and automated production. Through efficient feeding, precise stamping and bending, and real-time waste discharge functions, it can greatly shorten the production cycle and reduce the defective rate, meeting the stable supply demand of automobile OEMs, 3C OEM factories, and home appliance manufacturers for standardized parts. At the same time, it is suitable for the processing of strips of different materials (such as stainless steel, aluminum alloy, galvanized sheet), and flexibly adapts to the switching of multiple categories of orders.

[0003] However, in the existing stamping strip processing technology, most molds often face three major production problems: First, stamping relies on a simple rigid pressing mode, which makes it easy for punching to have problems such as hole position offset and bending angle deviation, and complex workpieces need to be positioned and processed multiple times. The yield rate is significantly affected by manual debugging and mechanical wear, and it is difficult to adapt to the production of parts with strict tolerance requirements such as high-precision electronic product housings or precision automobile hinges; Second, the strip feeding generally adopts intermittent gear meshing or one-way friction wheel transmission, and there is a risk of slipping, jamming and even breakage in the strip transportation. Especially when processing ultra-thin or high-strength strips, positioning errors cause fluctuations in the distance between adjacent workpieces, resulting in batch stamping waste; Third, the waste discharge system relies on a simple collection box, and the metal debris and scraps generated by stamping are easily accumulated around the mold cavity, causing the punch head to get stuck, the strip to be scratched, and even the equipment to short-circuit. Manual cleaning interrupts the production process, and waste wraps around the transmission components, causing shutdown failures.

[0004] In response to the above problems, the inventors proposed a continuous stamping and bending die for stamping strips to solve the above problems. Summary of the Invention

[0015] Preferably, a baffle is fixedly provided on the upper surface of the waste discharge rack.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention significantly improves the quality and efficiency of stamping operations through the innovative design of the stamping mechanism and multiple components. It adopts a symmetrical layout of two cylinders, and cooperates with the inclined sliding fitting structure of the driving inclined plate and the driven frame to accurately convert the linear motion of the cylinder into the vertical downward pressure of the stamping plate, ensuring that the punching die and the stamping die act on the material strip synchronously and smoothly, effectively avoiding the stamping offset or angle deviation problems caused by traditional rigid downward pressure. The elastic reset system composed of the reset rod and reset spring can quickly push the driven frame to reset after stamping is completed, so that the stamping plate can be quickly lifted, reducing non-production time and improving continuous operation efficiency.

[0018] 2. This invention achieves high-precision, stable conveying of stamped and bent material strips through the feeding mechanism, a dual innovation of mechanical transmission and material strip positioning. The motor transmits power stably to the feed wheel through a synchronous transmission system consisting of a drive rod, a driven rod, a transmission sprocket, and a chain, ensuring that the speeds of the feed wheels on both sides are completely synchronized, avoiding stretching or twisting of the material strip due to speed differences. The annular blocks on the surface of the feed wheel precisely engage with the bayonet holes on both sides of the material strip, achieving zero-slip feeding through physical engagement. The limit plates on both sides of the stamping table provide lateral constraints on the material strip.

[0019] 3. The present invention utilizes a waste discharge mechanism that utilizes power linkage and anti-blocking design to create an efficient and stable waste discharge system. Utilizing a sprocket and chain transmission structure linking the drive rod and drive wheel, the waste discharge power is synchronized with the punching power, precisely coupling the waste discharge speed with the punching frequency, thus avoiding waste accumulation caused by delayed waste discharge. Densely distributed anti-skid grooves and baffles on the conveyor belt surface form a dual anti-blocking mechanism. The anti-skid grooves increase friction to ensure stable adhesion of small waste materials such as metal scraps and scraps, while the baffles prevent waste from splashing due to inertia or airflow.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example 1: Figure 1-4 As shown, the present invention provides a continuous stamping and bending die for a stamping material strip, comprising a support frame 1, a feeding mechanism 3 is provided on the inner side of the support frame 1, a stamping and bending material strip 5 is provided inside the feeding mechanism 3, a stamping mechanism 2 is fixedly provided on the inner walls on both sides of the support frame 1, the stamping mechanism 2 is located above the stamping and bending material strip 5, a waste discharge mechanism 4 is fixedly provided on the inner walls on both sides of the support frame 1, and the waste discharge mechanism 4 is located below the stamping and bending material strip 5.

[0032] The stamping mechanism 2 includes a fixed plate 20, which is located between the inner walls on both sides of the support frame 1. Two symmetrically distributed cylinders 22 are provided on the lower surface of the fixed plate 20. A driving inclined plate 23 is fixed to the output end of the cylinder 22. A reset rod 29 is fixed to the lower surface of the fixed plate 20. A reset spring 28 is sleeved on the outer side of the reset rod 29. A driven frame 27 is slidingly provided on the outer side of the reset rod 29. The two sides of the driven frame 27 are respectively slidably fitted with the two driving inclined plates 23. A stamping plate 26 is fixed to the lower surface of the driven frame 27. A plurality of punching dies 24 and a plurality of stamping dies 25 are fixed on the lower surface of the stamping plate 26. The punching dies 24 and the stamping dies 25 are located above the stamping and bending strip 5.

[0033] By adopting the above technical solution, through the stamping mechanism 2, through the coordinated action of the cylinder 22, the driving inclined plate 23, the driven frame 27 and other components, the punching and bending operations can be completed efficiently and accurately to ensure the stamping quality; before the stamping operation begins, the cylinder 22 is in an initial contracted state, and the driven frame 27 is in a high position under the action of the return spring 28. When stamping, the output end of the cylinder 22 extends, pushing the driving inclined plate 23 to move downward. Since the sliding inclined surfaces 201 on both sides of the driven frame 27 slide and fit with the driving inclined plate 23, the downward movement of the driving inclined plate 23 forces the driven frame 27 to overcome the elastic force of the return spring 28 and slide downward along the return rod 29, thereby driving the stamping plate 26 to move downward. The punching die 24 and the stamping die 25 on the lower surface of the stamping plate 26 perform punching and bending operations on the corresponding positions above the stamping and bending strip 5. After the stamping is completed, the output end of the cylinder 22 contracts, and the elastic force of the reset spring 28 causes the driven frame 27 to slide upward along the reset rod 29 and reset, driving the stamping plate 26 back to the initial position and waiting for the next stamping.

[0034] A fixing frame 21 is provided on both sides of the fixing plate 20 . One side of the fixing frame 21 is fixedly connected to an inner wall of one side of the support frame 1 , and the lower surface of the fixing frame 21 is fixedly matched with the cylinder 22 .

[0035] By adopting the above technical solution, one side of the fixing frame 21 is fixedly connected to the inner wall of one side of the support frame 1, and the lower surface is fixedly matched with the cylinder 22, providing a stable installation position for the cylinder 22, enhancing the fixing strength of the cylinder 22, and effectively preventing the cylinder 22 from shaking or displacing due to force during operation, thereby ensuring the stability and accuracy of the movement of the inclined plate 23 driven by the cylinder 22, thereby improving the overall working reliability of the stamping mechanism 2, and enabling punching and bending operations to be performed more accurately.

[0036] Sliding inclined surfaces 201 are formed on both sides of the driven frame 27 , and the sliding inclined surfaces 201 are slidably fitted with one side of the driving inclined plate 23 .

[0037] By adopting the above technical solution, the sliding inclined surfaces 201 opened on both sides of the driven frame 27 slide and fit with one side of the driving inclined plate 23. This design enables the vertical movement of the driving inclined plate 23 to be smoothly converted into the horizontal movement of the driven frame 27 along the direction of the reset rod 29, realizing effective transmission and conversion of force, ensuring that the driven frame 27 can smoothly and accurately drive the stamping plate 26 to perform stamping action, reducing energy loss and mechanical wear during movement, improving the working efficiency and precision of the stamping mechanism 2, and extending the service life of the equipment.

[0038] Working principle: Before the stamping operation begins, the cylinder 22 is in an initial contracted state, and the driven frame 27 is in a high position under the action of the return spring 28. When stamping, the output end of the cylinder 22 extends, pushing the driving inclined plate 23 to move downward. Since the sliding inclined surfaces 201 on both sides of the driven frame 27 slide and fit with the driving inclined plate 23, the downward movement of the driving inclined plate 23 forces the driven frame 27 to overcome the elastic force of the return spring 28 and slide downward along the return rod 29, thereby driving the stamping plate 26 to move downward. The punching die 24 and the stamping die 25 on the lower surface of the stamping plate 26 perform punching and bending operations on the corresponding positions above the stamping and bending strip 5. After the stamping is completed, the output end of the cylinder 22 contracts, and the elastic force of the return spring 28 causes the driven frame 27 to slide upward along the return rod 29 and reset, driving the stamping plate 26 back to its initial position and waiting for the next stamping.

[0039] Example 2: Figure 5-6As shown, the feeding mechanism 3 includes a motor 30, one end of the motor 30 is fixedly connected to one side of the support frame 1, and a driving rod 32 is fixedly arranged at the output end of the motor 30. The inner walls of both sides of the support frame 1 are rotated together with a driven rod 38, and one end of the driven rod 38 and the driving rod 32 are fixed with a transmission sprocket 35, and the outer sides of the two transmission sprockets 35 are engaged with a transmission chain 33. The inner walls of both sides of the support frame 1 are jointly fixed with a stamping table 34, and the upper surface of the stamping table 34 is slidably fitted with the lower surface of the stamping and bending material strip 5. Feeding wheels 39 are fixedly arranged at both ends of the driven rod 38, and a plurality of annularly distributed clamping blocks 37 are fixedly arranged on the outer side of the feeding wheel 39. A plurality of equally spaced bayonet slots 36 are opened on both sides of the stamping and bending material strip 5, and the bayonet slots 36 are fitted with the clamping blocks 37.

[0040] By adopting the above technical solution, through the feeding mechanism 3, with the help of the motor 30, the transmission sprocket 35, the feeding wheel 39, etc., the stable transportation and precise positioning of the stamping and bending material strip 5 are achieved, ensuring the smooth progress of the continuous stamping operation; after the motor 30 is started, its output end drives the driving rod 32 to rotate, and the transmission sprocket 35 at one end of the driving rod 32 rotates accordingly, and drives the transmission sprocket 35 at one end of the driven rod 38 to rotate through the transmission chain 33, thereby causing the driven rod 38 to rotate. The feeding wheels 39 at both ends of the driven rod 38 rotate accordingly, and the blocking blocks 37 on the outside of the feeding wheel 39 fit into the blocking holes 36 on both sides of the stamping and bending material strip 5. As the feeding wheel 39 rotates, the blocking blocks 37 drive the stamping and bending material strip 5 to move forward on the stamping table 34. The stamping table 34 provides stable support for the stamping and bending material strip 5. The limiting plates 301 on both sides of the stamping table 34 limit the stamping and bending material strip 5 to prevent it from deviating, thereby realizing stable transportation and precise positioning of the stamping and bending material strip 5 for the next stamping operation.

[0041] A mounting bracket 31 is fixedly provided on one side of the support frame 1 , and one side of the mounting bracket 31 is fixedly matched with one end of the motor 30 .

[0042] By adopting the above technical solution, the mounting frame 31 fixed on one side of the support frame 1 is fixedly matched with one end of the motor 30, providing a reliable installation foundation for the motor 30, enhancing the fixing stability of the motor 30, and effectively reducing the noise and displacement caused by vibration of the motor 30 during operation, ensuring that the motor 30 can stably and efficiently transmit power to the drive rod 32, thereby ensuring that the feeding mechanism 3 can operate stably, realizing the precise delivery of the stamping and bending material strip 5, and improving the production efficiency and product quality of the entire mold.

[0043] Limiting plates 301 are fixedly provided on both sides of the punching platform 34 , and one side of the limiting plate 301 is slidably fitted with one side of the punched and bent material strip 5 .

[0044] By adopting the above-mentioned technical solution, the limit plates 301 fixed on both sides of the stamping table 34 slide and fit with one side of the stamping and bending material strip 5. During the conveying process of the stamping and bending material strip 5, the limit plates 301 can effectively limit the lateral movement of the stamping and bending material strip 5, preventing it from deviating due to vibration or external force during the conveying process, ensuring that the stamping and bending material strip 5 can accurately reach the stamping position, improving the positioning accuracy of the stamping and bending material strip 5, thereby ensuring the quality and stability of the stamping operation, and reducing the scrap rate caused by the deviation of the material strip.

[0045] Working principle: After the motor 30 is started, its output end drives the driving rod 32 to rotate, and the transmission sprocket 35 at one end of the driving rod 32 rotates accordingly. The transmission chain 33 drives the transmission sprocket 35 at one end of the driven rod 38 to rotate, thereby rotating the driven rod 38. The feed wheels 39 at both ends of the driven rod 38 rotate accordingly, and the clamping blocks 37 on the outside of the feed wheel 39 fit with the clamping blocks 36 on both sides of the stamping and bending material strip 5. As the feed wheel 39 rotates, the clamping blocks 37 drive the stamping and bending material strip 5 to move forward on the stamping table 34. The stamping table 34 provides stable support for the stamping and bending material strip 5. The limit plates 301 on both sides of the stamping table 34 limit the stamping and bending material strip 5 to prevent it from deviating, thereby achieving stable transportation and precise positioning of the stamping and bending material strip 5 for the next stamping operation.

[0046] Example 3: Figure 7-8 As shown, the waste discharge mechanism 4 includes a waste discharge frame 40, and the two sides of the waste discharge frame 40 are fixedly connected to the inner walls of the two sides of the support frame 1 respectively. The inner sides of the two ends of the waste discharge frame 40 are respectively rotatably provided with a driving wheel 41 and a driven wheel 45. The outer sides of the driving wheel 41 and the driven wheel 45 are jointly engaged and connected with a conveyor belt 46. One end of the driving rod 32 and the driving wheel 41 is fixed with a linkage sprocket 43, and the outer sides of the two linkage sprockets 43 are jointly engaged and connected with a linkage chain 42.

[0047] By adopting the above technical solution, the waste generated by stamping is promptly discharged through the waste discharge mechanism 4, utilizing the drive wheel 41, the driven wheel 45, the conveyor belt 46, etc., preventing waste accumulation from affecting production, improving waste discharge efficiency and stability, and ensuring a clean production environment and normal operation of the mold. When the drive rod 32 rotates, the linkage sprocket 43 at one end thereof rotates accordingly, driving the linkage sprocket 43 at one end of the drive wheel 41 through the linkage chain 42, thereby rotating the drive wheel 41, which in turn drives the driven wheel 45 through the conveyor belt 46. The waste generated during the stamping process will fall onto the conveyor belt 46. The multiple anti-skid grooves 47 on the outer surface of the conveyor belt 46 increase the friction between the waste and the conveyor belt 46, preventing the waste from slipping during transportation. The waste is promptly discharged as the conveyor belt 46 rotates. The baffle 44 on the upper surface of the waste discharge rack 40 prevents the waste from falling from both sides of the conveyor belt 46 during transportation, ensuring smooth waste discharge and preventing waste accumulation from affecting production.

[0048] A plurality of anti-slip grooves 47 are formed on the outer surface of the conveyor belt 46 .

[0049] By adopting the above technical solution, the multiple anti-slip grooves 47 opened on the outer surface of the conveyor belt 46 increase the friction between the waste and the conveyor belt 46. During the waste discharge process, it can effectively prevent the waste from slipping or accumulating on the conveyor belt 46, ensuring that the waste can be discharged smoothly with the rotation of the conveyor belt 46, thereby improving the waste discharge efficiency of the waste discharge mechanism 4, avoiding production interruptions or equipment failures caused by waste accumulation, ensuring the cleanliness of the production environment and the normal operation of the mold, and improving the continuity and stability of the entire production process.

[0050] A baffle 44 is fixedly provided on the upper surface of the waste discharge rack 40 .

[0051] By adopting the above technical solution, the baffle 44 fixed on the upper surface of the waste discharge rack 40 can prevent the waste from falling from both sides of the conveyor belt 46 during the transmission process, ensuring that the waste can be discharged smoothly along the predetermined path on the conveyor belt 46, avoiding the waste from being scattered around the equipment or other parts, further ensuring the cleanliness of the production environment, and at the same time reducing the potential damage to the equipment caused by the scattering of waste, thereby improving the stability and reliability of the waste discharge mechanism 4 and providing a strong guarantee for the long-term stable operation of the mold.

[0052] Working Principle: When the drive rod 32 rotates, the interlocking sprocket 43 at one end rotates accordingly. This interlocking chain 42 drives the interlocking sprocket 43 at one end of the drive wheel 41, which in turn rotates the drive wheel 41. The drive wheel 41 then drives the driven wheel 45 via the conveyor belt 46. Waste generated during the stamping process falls onto the conveyor belt 46. Multiple anti-skid grooves 47 on the outer surface of the conveyor belt 46 increase the friction between the waste and the conveyor belt 46, preventing the waste from slipping during transport. As the conveyor belt 46 rotates, the waste is promptly discharged. Baffles 44 on the upper surface of the waste discharge rack 40 prevent the waste from falling off the sides of the conveyor belt 46 during transport, ensuring smooth waste discharge and preventing waste accumulation that could affect production.
