Description

Technical Field

[0001] This invention relates to the field of stamping machine technology, and more specifically to an automatic part-removing stamping die device with waste separation function. Background Technology

[0002] A stamping press is a general-purpose forming equipment that uses power sources such as motors and hydraulic systems to provide pressure, driving a die to apply force to metal or non-metal blanks, causing them to undergo plastic deformation or separation, thereby mass-producing workpieces of preset shapes and sizes. The stamping die is the core forming tool assembly adapted to the stamping press. Its core function is to process the blank into workpieces with preset shapes, sizes, and precision requirements by working in conjunction with the stamping press's power system. Refer to the relevant patent CN114850322B. Essentially, it achieves material cutting and forming through a stamping structure in which the die plate and base plate cooperate. At the same time, the friction and telescopic components inside the stamping die are driven by drive components and rotating connecting components to perform rough grinding (forward friction) and fine grinding (reverse friction) on the outer peripheral surface of the stamped material. During the fine grinding stage, the burrs on the upper surface edge of the material are treated simultaneously. Anti-rotation guide structures such as anti-rotation friction barrels ensure the stability of the material. The synergistic effect of the two frictions enhances the burr removal effect, realizing the integrated operation of stamping and burr removal.

[0003] However, existing stamping presses generally suffer from drawbacks such as low automation, poor mold adaptability, insufficient process coordination, high equipment wear and tear, and inefficient separation of scrap and finished products, making it difficult to meet the needs of continuous and flexible production. Therefore, based on existing stamping technology, it is necessary to add scrap separation and automatic part removal functions to reduce human intervention, increase output, and avoid accidents caused by human operation of stamping equipment. At the same time, it is also necessary to integrate automatic feeding and guiding structures and split quick-change mold structures to further coordinate with scrap separation and automatic part removal functions, so as to achieve integrated operation of automatic and accurate feeding of stamping blanks, quick mold change, simultaneous completion of workpiece shaping and cutting, and classified collection of finished product scrap. To this end, we provide an automatic part removal stamping mold device with scrap separation function to solve the above problems. Summary of the Invention

[0015] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows: 1. This invention provides an automatic part-removing stamping die device with waste separation function. During the workpiece stamping process, the stamping execution unit cooperates with the split die to process the stamping blank into a specified shape. At the same time, the workpiece that has been stamped and shaped in the front part of the stamping blank is cut and separated. The limit rail restricts the excessive displacement of the stamping blank to ensure the dimensional accuracy of the workpiece. At this time, the waste generated by stamping falls into the waste discharge chute and is guided to fall onto the top surface of the discharge conveyor belt through the waste discharge outlet. It is then transported to a designated area for centralized collection by the discharge conveyor belt. The stamped workpiece slides along the surface of the guide net under the guidance of the internal components of the stamping execution unit, and falls to the top of the finished product conveyor belt with the assistance of the pulsed airflow sprayed by the part-picking nozzle and the protective structure inside the stamping base frame, thus achieving the technical goal of automatic part picking.

[0016] 2. The present invention provides an automatic part-removing stamping die device with waste separation function. By sliding the mounting sliders on the two split dies into the cavity of the limiting slide groove for assembly, and ensuring that the connecting guide slide grooves on the sides of the two split dies are engaged and positioned with the limiting connecting rod, the two split dies are spliced ​​to form a complete die base. At this time, the stamping blank can slide in along the side of the limiting guide plate and enter the subsequent stamping process in a preset posture.

[0017] 3. This invention provides an automatic part-retrieving stamping die device with waste separation function. After the split die is installed and fixed on the outer surface of the stamping platform, the adjusting push rod drives the fixed bracket to slide down along the limiting slide to the preset position. At this time, the stamping blank enters between the two feeding roller shafts under the guidance of the guide plate. Under the transmission of the drive gear, the feeding roller shafts transmit the stamping blank to the limiting guide plate, realizing the automatic feeding of the stamping blank and ensuring the continuous and automated operation of the stamping operation.

[0018] 4. This invention provides an automatic part-removing stamping die device with waste separation function. The punch mounting base is driven by a stamping drive rod to apply pressure downward at a preset uniform speed. The guide limiting groove on the bottom surface of the punch mounting base is fitted onto the top of the limiting slide rod. The limiting slide rod accurately limits the falling trajectory of the punch mounting base. At the same time, as the punch mounting base continues to descend, the spring buffer rod is compressed and deformed to achieve buffering and shock absorption, reducing rigid collisions between equipment parts and reducing the wear rate of the split die and the punch. When the stamping drive rod descends to the preset height, the punch contacts the stamping blank, simultaneously completing the first stage of workpiece shaping and the second stage of workpiece cutting and separation. After the workpiece is processed, the punch mounting base continues to press down, and the material picking block presses down on one end of the workpiece, causing the other end of the workpiece to lift up and fall into the material picking slot, preventing the workpiece from getting stuck with the punch, while ensuring that the workpiece is in contact with the surface of the guide protective net, ensuring the smooth progress of the subsequent automatic part picking process.

Detailed Implementation

[0021] The present invention will be further described in detail below with reference to embodiments: Example 1: As Figure 1-8 As shown, the present invention provides an automatic part-removing stamping die device with waste separation function, including a base plate 1. The top surface of the base plate 1 is provided with a stamping base unit 2, which can realize the classification and diversion of waste and target workpiece after the stamping process. The top surface of the stamping base unit 2 is provided with a stamping execution unit 3 with the function of quick mold replacement as needed. The stamping base unit 2 includes a stamping frame 21 fixedly installed on the top surface of the base plate 1, a stamping platform 24 set inside the top surface of the stamping base 21 as the workpiece and waste separation working surface, a discharge conveyor belt 22 set on the bottom surface of the stamping base 21 for directional waste conveying, and a finished product conveyor belt 23 set at the other end of the bottom surface of the stamping base 21 for finished workpiece removal and conveying. The stamping base frame 21 has two output ends inside, which face different directions and are used to classify, separate and output the target workpiece and the waste. There are four spring buffer rods 26, which are symmetrically arranged in pairs on both sides of the stamping base frame 21. The top surface of the spring buffer rods 26 is fixedly connected to the limiting slide rods 27 to realize the limiting and buffering functions of the punch mounting base 34. A spring buffer rod 26 is fixedly connected inside the top surface of the stamping base frame 21. A limit slide rod 27 is fixedly connected to the output end of the spring buffer rod 26. A stamping blank 25 is provided on the top surface of the stamping platform 24. A waste discharge chute 29 is opened inside the top surface of the stamping platform 24. A waste discharge outlet 210 is fixedly connected to the output end of the waste discharge chute 29. The waste discharge outlet 210 is movably connected to the top surface of the discharge conveyor belt 22. A limit slide 28 is opened inside the side of the stamping platform 24. A part-picking air nozzle 211 is fixedly connected inside the other side of the stamping platform 24. A guide protective net 212 is fixedly connected to the inner side of the part-picking air nozzle 211. A limit railing 213 is fixedly connected to the side of the stamping platform 24. The stamping platform 24 is fixed to the middle of the top surface of the stamping base 21. The side of the stamping platform 24 is provided with a guide groove for workpiece discharge. The part-retrieving air nozzle 211 is fixedly connected in the guide groove. The guide protective net 212 installed at the output end of the part-retrieving air nozzle 211 can prevent foreign objects from entering the part-retrieving air nozzle 211. The limiting rail 213 is fastened to the outer surface of the stamping platform 24 by bolts to limit the length of the stamping blank 25 and ensure that the size of a single workpiece meets the preset requirements.

[0022] In this embodiment, during the workpiece stamping process, the stamping execution unit 3 cooperates with the split mold 214 to process the stamping blank 25 into a specified shape. At the same time, the workpiece that has been stamped and shaped in the front part of the stamping blank 25 is cut and separated. The limiting rail 213 restricts the excessive displacement of the stamping blank 25 to ensure the dimensional accuracy of the workpiece. At this time, the waste generated by stamping falls into the waste discharge chute 29 and is guided to fall onto the top surface of the discharge conveyor belt 22 through the waste discharge outlet 210. It is then transported to a designated area for centralized collection by the discharge conveyor belt 22. The stamped workpiece slides along the surface of the guide net 212 under the guidance of the internal components of the stamping execution unit 3, and falls to the top surface of the finished product conveyor belt 23 with the assistance of the pulse airflow ejected by the part-picking nozzle 211 and the protective structure provided inside the stamping base frame 21, thus achieving the technical goal of automatic part picking.

[0023] Example 2: Figure 1-8 As shown, based on Embodiment 1, the present invention provides a technical solution: preferably, a split mold 214 is movably connected to the top surface of the stamping platform 24, an installation slider 216 is fixedly connected to the bottom side of the split mold 214, the installation slider 216 is snapped into the inside of the limiting slide groove 28, a limiting guide plate 217 is fixedly connected to the top surface of the split mold 214, and the stamping blank 25 is slidably connected to the inside of the limiting guide plate 217; The number of split molds 214 is two and they are arranged opposite each other. The mounting slider 216 is adapted to the limiting slide groove 28 to ensure the structural stability of the split mold 214 during operation. The side of the split mold 214 is equipped with fastening bolts for further reinforcement. The opposite surfaces of the two split molds 214 are respectively provided with connecting guide slide groove 219 and limiting connecting rod 215, which are adapted to each other to further improve the structural stability during the stamping process. The side of the split mold 214 has a connecting guide groove 219. The side of the other split mold 214 is fixedly connected to a limiting connecting rod 215. The limiting connecting rod 215 is slidably connected inside the connecting guide groove 219. The top surface of the split mold 214 has a stamping cavity 218. The stamping cavity 218 is opened on the top surface of the split mold 214. Through the coordinated cooperation of the stamping cavities 218 inside the two split molds 214, a forming basis is provided for subsequent stamping operations. The limiting guide plate 217 has a guide groove inside for guiding and limiting the stamping blank 25.

[0024] In this embodiment, by sliding the mounting sliders 216 on the two split molds 214 into the cavity of the limiting slide groove 28 and ensuring that the connecting guide slide groove 219 on the side of the two split molds 214 engages with the limiting connecting rod 215, the two split molds 214 are spliced ​​together to form a complete mold base. At this time, the stamping blank 25 can slide into the side of the limiting guide plate 217 and enter the subsequent stamping process in a preset posture.

[0025] Example 3: As Figure 1-8 As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, the stamping execution unit 3 includes a punch fixing plate 31 fixedly installed in the middle of the outer surface of the stamping base 21, a limiting slide 32 fixedly installed on the top side of the punch fixing plate 31 for guiding the stable feeding of the stamping raw material, and a punch mounting base 34 set on the top inner surface of the punch fixing plate 31 for completing the stamping forming operation. An adjustment push rod 35 is fixedly connected to the top inner surface of the limiting slide 32, and a fixed bracket 36 is fixedly connected to the output end of the adjustment push rod 35. A limiting block 310 is fixedly connected to the side of the fixed bracket 36, and the limiting block 310 is slidably connected to the inner side of the limiting slide 32. The fixed bracket 36 has two guide plates 39 fixedly connected to the side facing each other. The fixed bracket 36 has a feeding roller shaft 37 rotatably connected inside. One end of the feeding roller shaft 37 passes through the side of the fixed bracket 36 and is fixedly connected to a drive gear 38. The limiting slide 32 inside the punch fixing plate 31 can limit the fixed bracket 36, ensuring that the fixed bracket 36 can only move axially along the guiding direction of the limiting slide 32. The limiting block 310 further limits the movement trajectory of the fixed bracket 36 to avoid overtravel. Two oppositely arranged guide plates 39 are provided on the back of the fixed bracket 36 to guide and correct the stamping blank 25. The two feeding roller shafts 37 inside the fixed bracket 36 achieve reverse synchronous movement through the meshing drive gears 38, thereby driving the stamping blank 25 to be stably conveyed according to the preset rhythm. The output end of the feeding roller shaft 37 and the input end of the limiting guide plate 217 keep their axes coplanar to ensure smooth feeding.

[0026] In this embodiment, after the split mold 214 is installed and fixed on the outer surface of the stamping platform 24, the adjusting push rod 35 drives the fixed bracket 36 to slide down along the limiting slide 32 to the preset station. At this time, the stamping blank 25 enters between the two feeding roller shafts 37 under the guidance of the guide plate 39. Under the transmission cooperation of the drive gear 38, the feeding roller shaft 37 transmits the stamping blank 25 to the limiting guide plate 217, realizing the automatic feeding of the stamping blank 25 and ensuring the continuous and automated operation of the stamping operation.

[0027] Example 4: Figure 1-8 As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, a punching drive rod 33 is fixedly connected to the inner top of the punch fixing plate 31, a punch mounting base 34 is fixedly connected to the output end of the punch mounting base 34, a guide limiting groove 312 is opened at one end of the bottom surface of the punch mounting base 34, a limiting slide rod 27 is slidably connected inside the bottom surface of the guide limiting groove 312, and a mold locking slide groove 311 is opened at the bottom side of the punch mounting base 34; The limiting slide bar 27, which is fixedly connected to the top surface of the spring buffer rod 26, slides along the bottom surface of the guide limiting groove 312, thereby limiting the movement trajectory of the punch mounting base 34. When the punch mounting base 34 moves, it synchronously drives the spring buffer rod 26 to extend and retract. The elastic deformation of the spring buffer rod 26 buffers the rigid impact between the equipment parts and extends the service life of the equipment. The mold locking slide 311 is slidably connected to the mold guide slide block 314. The bottom surface of the mold guide slide block 314 is fixedly connected to the punch base 315. The bottom surface of the punch base 315 is fixedly connected to the punch head 316. The other end of the bottom surface of the punch base 315 is provided with a material picking groove 317. The side surface of the punch base 315 is fixedly connected to the material picking pressure block 313. The mold guide slide block 314 is adapted to and cooperates with the mold locking slide 311. The punch 316, which is fixedly connected to the bottom surface of the die base 315, has a two-stage operation function: the first stage completes the plastic forming of the target workpiece, and the second stage realizes the cutting and separation of the target workpiece and the stamping blank 25. The internal top cavity of the material taking movable groove 317 is reasonably designed to prevent the workpiece from getting stuck inside the groove. The installation height of the material taking pressure block 313 is higher than the working end face of the punch 316. The material taking pressure block 313 only contacts the workpiece after the punch 316 has completed the cutting and separation operation.

[0028] In this embodiment, the punch mounting base 34 is driven by the stamping drive rod 33 to apply pressure downward at a preset uniform speed. The guide limiting groove 312 on the bottom surface of the punch mounting base 34 is fitted onto the top of the limiting slide rod 27. The limiting slide rod 27 precisely limits the falling trajectory of the punch mounting base 34. At the same time, as the punch mounting base 34 continues to descend, the spring buffer rod 26 is compressed and deformed to achieve buffering and shock absorption, reduce rigid collisions between equipment parts, and reduce the wear rate of the split mold 214 and the punch 316. When the stamping drive rod 33 descends to the preset height, the punch 316 contacts the stamping blank 25, simultaneously completing the first stage of workpiece shaping and the second stage of workpiece cutting and separation. After the workpiece is processed, the punch mounting base 34 continues to press down, and the material taking block 313 presses one end of the workpiece, causing the other end of the workpiece to lift up and fall into the material taking movable groove 317, preventing the workpiece from getting stuck with the punch 316, while ensuring that the workpiece is attached to the surface of the guide protective net 212, ensuring the smooth progress of the subsequent automatic part taking process.

[0029] The working principle of this automatic part-removing stamping die device with waste separation function will be explained in detail below.

[0030] like Figure 1-8 As shown, by sliding the mounting sliders 216 on the two split molds 214 into place along the cavity of the limiting slide groove 28, and ensuring that the connecting guide slide groove 219 on the side of the two split molds 214 and the limiting connecting rod 215 are engaged and positioned, the two split molds 214 are spliced ​​together to form a complete mold base. At this time, the stamping blank 25 can slide in along the side of the limiting guide plate 217 and enter the subsequent stamping forming process with a preset precise posture; After the split mold 214 is installed and fixed on the outer surface of the stamping platform 24, the adjusting push rod 35 drives the fixed bracket 36 to slide down along the limiting slide 32 to the preset working position. At this time, the stamping blank 25 enters between the two feeding roller shafts 37 under the guiding and correcting action of the guide plate 39. Under the meshing and transmission of the drive gear 38, the feeding roller shaft 37 smoothly transmits the stamping blank 25 into the limiting guide plate 217, realizing the automatic and precise feeding of the stamping blank 25 and ensuring the continuous and automated operation of the stamping operation. During the stamping process, the stamping execution unit 3 and the split mold 214 work together to process the stamping blank 25 into a preset shape, and simultaneously complete the cutting and separation of the stamped workpiece in front of the stamping blank 25; the limiting rail 213 restricts the excessive displacement of the stamping blank 25 to ensure that the workpiece size meets the preset tolerance requirements. At this time, the waste generated by stamping naturally falls into the waste discharge chute 29, and after being guided by the waste discharge outlet 210, it falls to the top surface of the discharge conveyor belt 22, and is transported by the discharge conveyor belt 22 to a designated area for centralized recycling and processing; The stamping drive rod 33 drives the punch mounting base 34 to apply a stamping load downward at a preset uniform speed. The guide limiting groove 312 on the bottom surface of the punch mounting base 34 is fitted onto the top of the limiting slide rod 27. The limiting slide rod 27 precisely constrains the downward trajectory of the punch mounting base 34. At the same time, as the punch mounting base 34 continues to descend, the spring buffer rod 26 is compressed and deformed to achieve buffering and shock absorption, reduce rigid collisions between equipment parts, reduce the wear rate of the split mold 214 and the punch 316, and extend their service life. When the stamping drive rod 33 descends to the preset stamping height, the punch 316 contacts the stamping blank 25, simultaneously performing the first stage of workpiece shaping and the second stage of workpiece cutting and separation. After the workpiece is processed, the punch mounting base 34 continues to press down, and the material taking block 313 presses one end of the workpiece, causing the other end of the workpiece to lift up and fall accurately into the cavity of the material taking movable groove 317, avoiding the workpiece from getting stuck with the punch 316, while ensuring that the workpiece is tightly attached to the surface of the guide protective net 212, providing a guarantee for the smooth operation of the subsequent automatic part taking process. The stamped workpiece slides smoothly along the surface of the guide net 212 under the limiting and guiding action of the guide component inside the stamping execution unit 3; and with the assistance of the pulsed airflow sprayed by the part-picking nozzle 211 and the internal protective guide structure of the stamping base frame 21, it falls precisely onto the top surface of the finished product conveyor belt 23, achieving the technical effect of automatic part picking.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements made without departing from the spirit of the present invention are within the scope of protection of the present invention.
