Description

Technical Field

[0001] This invention relates to the field of stamping technology, and more specifically, to a metal stamping press with a waste collection device. Background Technology

[0002] Traditional stamping presses lack dedicated collection devices, and the waste generated during stamping relies mostly on manual sweeping or simple material chutes for collection. The waste is scattered around the equipment, which not only seriously pollutes the working environment, but also requires frequent shutdowns for cleaning, interrupting the continuous production process and significantly reducing the efficiency of stamping operations. Because stamping waste has a chaotic shape, including various irregular shapes such as long strips and curls, it is very easy for it to overlap and pile up after falling into the receiving hopper, forming an arch bridge effect. This causes the waste to become stuck in the receiving hopper, frequently blocking it and requiring manual intervention to clear the blockage, which seriously restricts the continuity of waste collection. The waste falls into the receiving hopper and is tangled and disordered during the conveying process, resulting in the waste overlapping and piling up on the conveyor belt, increasing the conveying resistance, and making it easy for it to slip and flow back when tilted and lifted. At the same time, the waste in the collection box is loose and has a low density, resulting in a short cleaning cycle. The overall collection efficiency is difficult to meet the needs of industrial production. Summary of the Invention

[0003] To overcome the above-mentioned technical problems, the present invention proposes a metal stamping machine with a waste collection device.

[0004] The objective of this invention can be achieved through the following technical solutions: A metal stamping press with a waste collection device includes: A stamping unit includes a frame, a stamping table disposed at the bottom of the frame, and a stamping part that is vertically and flexibly disposed above the stamping table; The collection unit includes a receiving hopper located below the frame and a collection box located on one side of the frame. A conveyor belt connects the receiving hopper and the collection box, and a drive motor is installed on one side of the bottom of the conveyor belt. A dredging component and a combing component are arranged sequentially from top to bottom inside the receiving hopper.

[0005] As a further aspect of the present invention: several partitions are equidistantly arranged on the conveyor belt, and adjacent partitions are separated to form a receiving cavity.

[0006] As a further aspect of the present invention: the combing component includes two sets of rotating drums rotatably mounted in the receiving hopper, each set of rotating drums being provided with a plurality of staggered combing teeth, and each set of rotating drums having meshing transmission gears installed at its ends.

[0007] As a further aspect of the present invention: a set of rotating drums are coaxially fixed with a transmission shaft at their ends, and the transmission shaft is connected to the output end of the drive motor via a first transmission belt.

[0008] As a further aspect of the present invention: the unblocking component includes several sets of guide rods evenly distributed in the receiving hopper, a slider is slidably sleeved on the guide rod, several unblocking teeth are provided on the upper and lower sides of the slider and are staggered with the guide rod, and springs that abut against the slider are movably sleeved on the guide rods on both sides.

[0009] As a further aspect of the present invention: a crank is eccentrically connected to the transmission shaft, a journal is provided at the end of the crank away from the transmission shaft, a pull rod is connected to one end of the slider and moves through the receiving hopper, an elastic band is connected between the pull rod and the journal, and a through groove for accommodating the pull rod is provided on one side of the receiving hopper.

[0010] As a further aspect of the present invention: the stamping table includes a table surface and a collection bin at the bottom of the table surface, a plurality of material collection troughs communicating with the collection bin are equally spaced on the table surface, and a discharge port connected to a receiving hopper is provided at the bottom of the collection bin.

[0011] As a further aspect of the present invention: the stamping part includes a lifting slide mounted vertically on the top of the frame, a stamping head provided at the bottom of the lifting slide, a transverse slide rail provided inside the frame, a piston cylinder horizontally slidably embedded in the transverse slide rail, a flexible rocker arm hinged to the stamping head, the top of the flexible rocker arm hinged to the inner wall of the frame, and a first connecting rod hinged between the piston cylinder and the middle of the flexible rocker arm; a stamping drive component for driving the piston cylinder is also provided inside the frame.

[0012] As a further aspect of the present invention: the stamping drive includes a turntable rotatably mounted in the frame, a second connecting rod is eccentrically hinged on the turntable, the end of the second connecting rod away from the turntable is hinged to the piston cylinder, and a drive gear is coaxially fixed on the turntable.

[0013] As a further embodiment of the present invention: a stamping motor is installed at the bottom of the frame, and a transition shaft and a primary gear are rotatably installed in the frame. A second transmission belt is connected between the output end of the stamping motor and the primary gear. A flywheel and a secondary gear are respectively provided at both ends of the transition shaft, and the secondary gear meshes with the primary gear and the drive gear respectively.

[0014] The beneficial effects of this invention are: Through the coordinated operation of the stamping unit and the collection unit, the waste generated by the stamping parts falls directly into the receiving hopper under the action of gravity, and is automatically lifted and transported to the collection box by the conveyor belt driven by the drive motor. This not only avoids the waste from scattering and polluting the working environment, but also greatly reduces the frequency of downtime for cleaning, providing a reliable guarantee for waste post-processing for continuous stamping production. Inside the receiving hopper, unblocking and combing components are installed vertically. When waste falls in, the unblocking components first actively break the arch bridge effect formed by the waste accumulation, eliminating the risk of instantaneous bridging and blockage. Then, the combing components straighten the direction of the waste, so that the waste has completed the pre-adjustment of its shape and arrangement before entering the conveyor belt, overcoming the technical pain point of frequent jamming in traditional receiving hoppers due to the messy shape of waste. After being sorted by the combing components, the waste materials tend to be arranged in a consistent direction and fall onto the conveyor belt to form a regular single-layer or quasi-single-layer material flow. This orderly arrangement not only effectively prevents the waste materials from tangling, overlapping or slipping during transportation and reduces transportation resistance, but also increases the waste material accumulation density in the collection box, extends the box cleaning cycle, and improves the overall collection efficiency.

[0018] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0019] Please see Figure 1 The present invention discloses a metal stamping machine with a waste collection device, comprising a stamping unit 200 and a collection unit 100; Please see Figure 2 The stamping unit 200 includes a frame 210, a stamping table 220 disposed at the bottom of the frame 210, and a stamping part 230 disposed above the stamping table 220 in a height-adjustable manner. Please see Figure 3 The collection unit 100 includes a receiving hopper 110 disposed below the frame 210 and a collection box 120 located on one side of the frame 210. A conveyor belt 130 is connected between the receiving hopper 110 and the collection box 120. A drive motor 140 is disposed on one side of the bottom of the conveyor belt 130. A dredging component 160 and a combing component 150 are disposed sequentially from top to bottom inside the receiving hopper 110.

[0020] Specifically, the stamping part 230 stamps the sheet metal placed on the stamping table 220, and the waste generated by stamping falls into the receiving hopper 110 below the stamping table 220. Then, the drive motor 140 drives the conveyor belt 130 to move, thereby continuously conveying and lifting the waste in the receiving hopper 110 to the collection box 120 for unified collection. During the process of the waste falling into the receiving hopper 110, the messy waste is first cleared by the unblocking part 160 above to avoid the waste from forming an arch bridge effect and causing blockage in the receiving hopper 110. Then, the waste is combed by the combing part 150 below to make the waste oriented in a basically consistent direction. After the primary unblocking and secondary combing, the waste falls onto the conveyor belt 130 and is arranged in an orderly manner, improving the waste collection efficiency.

[0021] It should be noted that, through the coordinated operation of the stamping unit 200 and the collection unit 100, the waste generated by the stamping part 230 falls directly into the receiving hopper 110 under the action of gravity, and is automatically lifted and transported to the collection box 120 by the conveyor belt 130 driven by the drive motor 140. This not only avoids the waste from scattering and polluting the working environment, but also greatly reduces the frequency of downtime for cleaning, providing a reliable guarantee for waste post-processing for continuous stamping production. Inside the receiving hopper 110, there are vertically distributed unblocking components 160 and combing components 150. When waste falls in, the unblocking components 160 first actively break the arch bridge effect formed by the stacking of waste, eliminating the risk of instantaneous bridging and blockage. Then, the combing components 150 straighten the orientation of the waste, so that the waste has completed the pre-adjustment of its shape and arrangement before entering the conveyor belt 130, overcoming the technical pain point of frequent jamming in traditional receiving hoppers due to the messy shape of waste. After being sorted by the comb 150, the waste material tends to be arranged in a consistent direction and falls onto the conveyor belt 130 to form a regular single-layer or quasi-single-layer material flow. This orderly arrangement not only effectively prevents the waste material from tangling, overlapping or slipping during the transportation process and reduces the transportation resistance, but also increases the waste material accumulation density in the collection box 120, extends the box cleaning cycle, and substantially improves the overall collection efficiency.

[0022] In one embodiment, please refer to Figure 3 The conveyor belt 130 is provided with several partitions 131 at equal intervals, and adjacent partitions 131 are separated to form a receiving cavity 132; Specifically, during the process of conveying waste, the waste processed by the combing component 150 and the unblocking component 160 falls sequentially into the corresponding receiving cavity 132 below, thereby conveying the waste in batches. By setting partitions 131 at equal intervals on the conveyor belt 130, adjacent partitions 131 are naturally separated to form independent receiving cavities 132. Although the waste materials processed by the unblocking component 160 and the combing component 150 are in the same direction, they are very easy to collide with each other again and become messy again during the vibration or tilting lifting process of the conveyor belt 130. The introduction of the receiving cavity 132 provides an independent physical isolation space for each batch of waste materials, effectively limiting the relative displacement and tumbling of the waste materials during the conveying process, and ensuring that the waste materials are stably conveyed to the collection box 120 in an orderly manner. When conveying waste at an angle, the flat conveyor belt without side guards is prone to causing the waste to slide or roll down due to the component of gravity. The partition 131, as a rigid baffle, works together with the receiving cavity 132 to form a bucket lifting structure. Even at a large lifting angle, the waste can be steadily supported in the cavity by the partition 131, effectively avoiding slippage and backflow. The receiving cavity 132 moves cyclically with the conveyor belt 130, and the waste material falls into the corresponding cavity one by one, forming a regular filling rhythm. This avoids the waste material after the upstream unblocking component 160 is cleared from flowing into the narrow entrance of the conveyor belt 130 in large quantities at the same time. It decomposes the concentrated flow impact into a uniform sequential supply, which not only protects the conveyor belt 130 from the instantaneous heavy load impact, but also greatly reduces the risk of secondary blockage induced by sudden flow changes at the discharge end of the receiving hopper 110.

[0023] Further, please refer to Figure 4 , Figure 5 and Figure 6 The combing component 150 includes two sets of rotating drums 151 rotatably mounted in the receiving hopper 110. Each set of rotating drums 151 is provided with a plurality of staggered combing teeth 155, and each set of rotating drums 151 is provided with a transmission gear 152 that meshes with each other. A drive shaft 153 is coaxially fixed to the end of a set of rotating drums 151. The drive shaft 153 is connected to the output end of the drive motor 140 via a first drive belt 154. Specifically, while the drive motor 140 drives the conveyor belt 130, it drives the transmission shaft 153 to rotate synchronously under the transmission of the first transmission belt 154. Thus, by using the meshing transmission of the two sets of transmission gears 152, the two sets of rotating drums 151 rotate synchronously in opposite directions. The combing teeth 155 distributed on the two sets of transmission shafts 153 comb and guide the waste material falling into the receiving hopper 110, so that the arrangement of each waste material tends to be consistent.

[0024] It is worth noting that while the drive motor 140 drives the conveyor belt 130 to operate, it synchronously distributes the single power source to the two sets of rotating drums 151 through the cascade transmission of the first transmission belt 154, the transmission shaft 153 and the meshing transmission gears 152. This ensures that the conveying rhythm of the conveyor belt 130 and the combing rhythm of the rotating drums 151 are always in strict synchronization, avoiding material accumulation or idling caused by speed adjustment deviations of multiple power sources. Two sets of rotating drums 151 achieve precise synchronous rotation in opposite directions under the meshing drive of transmission gears 152. Together with the interlaced combing teeth 155 on them, they form a dynamic combing working surface for rolling and kneading. When the waste material falls between the two rotating drums 151, it is subjected to the alternating pushing and guiding action of the combing teeth 155 rotating in opposite directions on both sides, which can force the bent and hooked waste material to be flattened and discharged along the tangential direction of rotation, thereby improving the consistency of the waste material arrangement orientation. When the combing teeth 155, which are staggered on the two sets of rotating drums 151, rotate in opposite directions, they continuously apply a shearing force to the falling waste material. Even if a small amount of tangled waste material is not completely broken up by the unblocking component 160, it will be forcibly torn apart when it enters the staggered area of ​​the combing teeth 155.

[0025] Furthermore, please refer to Figure 5 and Figure 6 The unblocking component 160 includes several sets of guide rods 161 evenly distributed in the receiving hopper 110. A slider 162 is slidably sleeved on the guide rods 161. Several unblocking teeth 164 are provided on the upper and lower sides of the slider 162, which are staggered with the guide rods 161. Springs 163 that abut against the slider 162 are movably sleeved on the guide rods 161 on both sides. A crank 166 is eccentrically connected to the drive shaft 153. A journal 167 is provided at the end of the crank 166 away from the drive shaft 153. A pull rod 165 is connected to one end of the slider 162 and moves through the receiving hopper 110. An elastic band 168 is connected between the pull rod 165 and the journal 167. A through groove 111 is provided on one side of the receiving hopper 110 to accommodate the pull rod 165. Specifically, when the drive shaft 153 rotates, it drives the crank 166 to rotate synchronously, thereby causing the journal 167 to rotate circumferentially around the drive shaft 153. Then, the elastic band 168 pulls the pull rod 165, causing the slider 162 to slide horizontally along the guide rod 161, so as to achieve the lateral unblocking effect of the unblocking tooth 164 connecting with the waste material falling into the hopper 110. When the elastic band 168 pulls the slider 162 to slide towards the spring 163, the spring 163 is gradually compressed. Then, the spring 163 pops the slider 162 out and slides back to its original position. By repeating this process, the reciprocating movement of the slider 162 can achieve the unblocking effect.

[0026] It should be noted that while the drive motor 140 drives the conveyor belt 130 and the combing part 150 to operate, it also converts the single rotational power into the reciprocating linear motion of the slider 162 along the guide rod 161 through the cascade transmission of the crank 166, journal 167, elastic belt 168 and pull rod 165 on the transmission shaft 153. An elastic band 168 connects the journal 167 and the pull rod 165, and works with the spring 163 to form a composite drive mode of "elastic traction + energy storage ejection". When the crank 166 pulls the slider 162 to compress the spring 163, the elastic band 168 can buffer the instantaneous impact of the crank 166. When the crank 166 turns to the release position, the elastic potential energy stored in the spring 163 will quickly eject the slider 162. This flexible combination makes the reciprocating speed and amplitude of the slider 162 not constant, forming an adaptive unblocking effect and greatly improving the adaptability to different waste forms. The opposing rotation of the two sets of rotating drums 151 in the upstream combing component 150 provides longitudinal (along the direction of waste falling) forced guidance, while the slider 162 in this unblocking component 160 drives the unblocking teeth 164 to slide horizontally back and forth along the guide rod 161, thus dynamically cutting and loosening the waste layer from the vertical direction. The two sets of actions are arranged orthogonally in space. During the fall, the waste is first repeatedly "sawing" and breaking the arch bridge structure by the horizontal back and forth unblocking teeth 164, and then guided by the longitudinal rolling combing teeth 155, forming a dual active intervention process of "first horizontally breaking the arch, then longitudinally guiding". It has a strong destructive removal ability, especially for the entanglement and blockage of long strip and curled metal waste. The through slot 111 on one side of the receiving hopper 110 provides a through channel for the pull rod 165. Meanwhile, the elastic band 168, as a flexible connector, allows for a certain amount of elastic deformation during the process of the crank 166 driving the pull rod 165. When the unclogging teeth 164 encounter hard waste material and become stuck, causing the slider 162 to be unable to continue sliding, the elastic band 168 can be passively stretched to absorb the continued rotation stroke of the crank 166, preventing the rigid rod from being forcibly pushed and damaging the tooth tips or burning out the motor. At the same time, the instantaneous acceleration generated by the slider 162 when the spring 163 returns to its original position can cause the unclogging teeth 164 to vibrate slightly, shaking off the adhering waste debris and playing a self-cleaning role.

[0027] In yet another embodiment, please refer to Figure 7 The stamping table 220 includes a table surface 221 and a collection bin 222 opened at the bottom of the table surface 221. A plurality of material collection troughs 223 communicating with the collection bin 222 are equally spaced on the table surface 221. A discharge port 224 connected to the receiving hopper 110 is opened at the bottom of the collection bin 222. Specifically, the waste generated after stamping falls into each collection trough 223, and then enters the collection bin 222, and falls into the receiving hopper 110 through the discharge port 224 along the bottom slope of the collection bin 222.

[0028] Further, please refer to Figure 8 and Figure 9 The stamping part 230 includes a lifting slide 231 vertically slidably mounted on the top of the frame 210, a stamping head 232 provided at the bottom of the lifting slide 231, a transverse slide rail 233 provided inside the frame 210, a piston cylinder 234 horizontally slidably embedded in the transverse slide rail 233, a flexible rocker arm 235 hinged to the stamping head 232, the top of the flexible rocker arm 235 hinged to the inner wall of the frame 210, and a first connecting rod 236 hinged between the piston cylinder 234 and the flexible rocker arm 235 at the middle; a stamping drive part 240 for driving the piston cylinder 234 is also provided inside the frame 210. The stamping drive component 240 includes a turntable 241 rotatably mounted in the frame 210. A second connecting rod 242 is eccentrically hinged to the turntable 241. One end of the second connecting rod 242 away from the turntable 241 is hinged to the piston cylinder 234. A drive gear 243 is coaxially fixed on the turntable 241. A stamping motor 250 is installed at the bottom of the frame 210. A transition shaft 260 and a primary gear 270 are also rotatably installed inside the frame 210. A second transmission belt 280 connects the output end of the stamping motor 250 and the primary gear 270. A flywheel 261 and a secondary gear 262 are respectively provided at both ends of the transition shaft 260. The secondary gear 262 meshes with the primary gear 270 and the drive gear 243 respectively.

[0029] Specifically, under the transmission of the second transmission belt 280, the stamping motor 250 drives the first-stage gear 270 to rotate. Subsequently, the first-stage gear 270 drives the second-stage gear 262 to rotate, and drives the flywheel 261 to rotate and store energy. Then, it drives the drive gear 243, i.e., the turntable 241, to rotate, thereby reducing speed and increasing torque. Finally, the second connecting rod 242 pushes the piston cylinder 234 to slide back and forth in the transverse slide rail 233. Under the transmission of the first connecting rod 236, the flexible swing arm 235 can be driven to swing back and forth around the upper hinge point. The height of the lower hinge point of the flexible swing arm 235 changes continuously, thereby driving the lifting slide 231 to move up and down in the frame 210 to realize the stamping action of the stamping head 232.

[0030] It is worth noting that the power of the stamping motor 250 is transmitted to the first-stage gear 270 via the second transmission belt 280, which then drives the second-stage gear 262 and drives the flywheel 261 to rotate and store energy. Subsequently, the flywheel 261 is driven by the drive gear 243. The flywheel 261 stores rotational kinetic energy during the stamping interval and releases auxiliary torque at the moment the stamping head 232 contacts the sheet metal, effectively suppressing the impact of sudden changes in stamping load on the stamping motor 250. At the same time, the reduction cascade formed by the first-stage gear 270, the second-stage gear 262 and the drive gear 243 significantly increases the output torque while reducing the speed, so that a stamping motor 250 with a smaller power can generate sufficient stamping force, which reduces the energy consumption and manufacturing cost of the whole machine and extends the service life of the stamping motor 250 under heavy load conditions. The piston cylinder 234 slides horizontally back and forth within the transverse slide rail 233. The first connecting rod 236 drives the flexible rocker arm 235 to swing back and forth around its top hinge point. The periodic change in the height of the lower hinge point of the flexible rocker arm 235 drives the lifting slide block 231 to move vertically up and down along the frame 210. Compared with the conventional crank-slider direct impact method, its motion acceleration curve is smoother, which is especially suitable for the stamping process curve requirements of slow contact-fast pressure-smooth return of metal sheet, effectively improving the forming quality of the stamped part 230. The flexible rocker arm 235 has a certain elastic deformation capability. When the stamping head 232 contacts the sheet metal and generates a huge instantaneous recoil force, the flexible rocker arm 235 can absorb part of the impact energy through slight bending. This prevents the rigid connecting rod from directly transmitting the impact load to precision components such as the first connecting rod 236, piston cylinder 234, and even drive gear 243, which greatly reduces the vibration and noise of the whole machine. At the same time, it protects the stamping head 232 from the risk of hard chipping. It is especially suitable for adaptive stamping of metal sheets with uneven thickness or fluctuating hardness.

[0031] The specific embodiments of the present invention have been described above. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention, all of which are within the protection scope of the present invention.
