Abstract
Description
Technical Field
[0001] This disclosure relates to the field of mold technology, and in particular to waste discharge devices and stamping die devices. Background Technology
[0002] In modern metal processing technologies, such as stamping, cutting, and forming, various types of waste are inevitably generated, including scrap, chips, and other residual materials. Especially for small pieces of waste, the handling method affects the stability of equipment operation, production efficiency, and the quality of the final product. In related technologies, waste handling typically relies on the waste's own gravity to fall naturally into the lower die or a specially designed waste collection area. Due to the small size and light weight of the waste, it sometimes cannot fall smoothly by gravity alone and easily gets stuck in the die structure or other obstacles, causing blockages. Once blockages or residues occur, manual intervention to clean the die is often required, increasing downtime and labor costs, and reducing production efficiency. Current air blowing operations are usually based on fixed time points, lacking real-time monitoring and intelligent control, making it difficult to dynamically adjust the timing and intensity of air blowing according to actual conditions, thus leading to blockages in the waste discharge device. Summary of the Invention
[0003] In view of the shortcomings of the prior art described above, the purpose of this disclosure is to provide a waste discharge device and a stamping die device to solve the problems in the related art.
[0004] The first aspect of this disclosure provides a waste discharge device, comprising:

[0006] A blocking member is movably and vertically disposed above the storage section, forming a storage space for storing the waste material between itself and the storage section;
[0007] At least one sensor is configured to cooperate with the blocking member to generate a trigger signal when the blocking member is sensed to be in a preset position;
[0008] The discharge mechanism, provided corresponding to the storage section and communicatively connected to the sensor, is configured to perform a cleaning action on the storage space in response to the trigger signal, thereby removing waste material from the storage space.
[0009] In the first aspect of the embodiment, a lifting mechanism is further included to drive the blocking member, the lifting mechanism including: at least one set of guide grooves and connecting rods;
[0010] The guide groove is provided to extend in the vertical direction;
[0011] The connecting rod is slidably disposed in the guide groove, and one end is connected to the blocking member.
[0012] In the embodiments of the first aspect, it further includes:
[0013] An elastic element, deformably disposed within the guide groove by the upward movement of the connecting rod, provides a downward restoring force applied to the connecting rod during deformation.
[0014] In an embodiment of the first aspect, the sensor includes a contact sensor located at a preset position, configured to generate the trigger signal based on a contact signal from the blocking member; and / or, the sensor includes a non-contact sensor positioned relative to the blocking member at a preset sensing distance.
[0015] In the first aspect of the embodiment, a pair of sensors are provided, respectively disposed on opposite sides of the blocking member.
[0016] In an embodiment of the first aspect, the blocking member has an extension extending beyond the storage space, and the sensor is located at the position of sensing the extension.
[0017] In the first aspect of the embodiment, the waste inlet and the waste outlet are misaligned in the vertical direction.
[0018] In a first aspect embodiment, the blocking member is further connected to a guide plate along the discharge direction of the waste material, and the guide plate is at a preset angle to guide the waste material to slide out of the main body through the guide plate.
[0019] In an embodiment of the first aspect, the emission mechanism is one of a blowing mechanism, a suction mechanism, or a mechanical mechanism that moves waste.
[0020] A second aspect of this disclosure provides a stamping die apparatus, comprising:
[0021] The upper and lower molds work together;
[0022] At least one of the upper and lower dies includes a punch, one end of which is provided with a die opening for punching, which is connected to the die opening and the discharge channel respectively.
[0023] The waste discharge device described in any of the above-mentioned items is located in the mold where the punch is located, and its waste output channel is connected to the end of the discharge channel away from the mold opening.
[0024] The beneficial effects of this disclosure are as follows: When the sensor detects waste residue, the discharge mechanism automatically performs a cleaning action to remove the waste from the storage space, thereby further reducing the possibility of waste accumulation. Since the waste discharge process is automated, waste discharge and cleaning can be completed without manual intervention, greatly reducing equipment downtime caused by waste blockage or residue. Timely discharge and cleaning of waste also effectively avoids mold jamming or process deviations caused by waste residue, thereby reducing the defect rate and improving the product qualification rate.

[0038] In related technologies, gravity is relied upon to expel waste from the mold. However, for small, lightweight waste, relying solely on gravity is often insufficient to ensure its smooth discharge.
[0039] To address the aforementioned problems, this disclosure provides a waste discharge device in one embodiment, which please refer to. Figures 1 to 4 In this embodiment, the waste discharge device includes: a main body 200 with a waste inlet 101, a blocking member 220, at least one sensor 230, and a discharge mechanism 240. During operation, when the sensor 230 detects waste residue, the discharge mechanism 240 automatically performs a cleaning action to remove the waste from the storage space, thereby further reducing the possibility of waste retention.
[0040] Specifically, the main body 200 is also provided with a storage section 210; the storage section 210 is used to temporarily store the waste discharged from the waste output channel 100. The storage section is connected to one end of the vertically extending waste output channel via the waste outlet, ensuring that the waste can fall naturally or be pushed into the storage section 210; the other end of the waste output channel forms a waste inlet.
[0041] The waste output channel 100 extends vertically, with a waste inlet 101 for waste to enter and a waste outlet 102 for waste to exit. In some embodiments, the waste inlet 101 is located at the lower end of the waste output channel 100, and the waste outlet 102 is located at the upper end of the waste output channel 100. A blanking die orifice is provided at the waste inlet 101 to contact the stamping material. The blanking die orifice is used to create a target hole in the stamping material. In actual operation, multiple blanking dies with different diameters can be provided to adapt to different stamping requirements. In some embodiments, a corresponding waste output channel 100 may be provided only for blanking dies with diameters smaller than a specific size. The waste outlet 102 leads to the external environment or an external discharge device, allowing the stamping waste generated during stamping to be discharged through the waste output channel 100. For larger diameter punching dies, the waste material generated can fall directly onto the lower die plate due to its own weight, without needing to go through the waste output channel 100.
[0042] The blocking member 220 is movably and vertically disposed above the storage section 210, forming a storage space for storing the waste material between itself and the storage section 210. Figure 2 In this embodiment, the blocking member 220 covers the storage section 210, thereby forming a storage space. Waste material travels from the waste outlet 102 to the storage section 210 and enters the storage space formed between the storage section 210 and the blocking member 220. It is understood that as the waste material filling the storage section 210 accumulates, it will support the blocking member 220. The sensor 230 is configured in responsive cooperation with the blocking member 220 to generate a trigger signal when the blocking member 220 is detected to be in a preset position. For example, when the waste material in the storage space reaches a certain amount, the blocking member 220 is supported to the preset position, thereby generating the trigger signal. When the sensor 230 issues the trigger signal, the discharge mechanism 240 corresponding to the storage section 210 will immediately respond and perform a cleaning action to remove the waste material from the storage space. The discharge mechanism 240 can use various methods such as air blowing, push rods, and vibration for cleaning; the most suitable method can be selected based on the actual situation to ensure thorough removal of waste.
[0043] The specific process is as follows: Waste material enters the storage section 210 through the waste output channel 100, gradually accumulating in the storage space. Sensor 230 monitors the position of the blocking component 220 in real time. When the waste material accumulates to a preset position, sensor 230 generates a trigger signal. The trigger signal is sent to the discharge mechanism 240, notifying it to initiate a cleaning operation. The discharge mechanism 240 selects an appropriate cleaning method (such as air blowing, push rod, or vibration) based on the actual situation to remove the waste material from the storage section 210.
[0044] Alternatively, please refer to Figure 2The enlarged view at point F in the embodiment shows that the waste discharge device further includes a lifting mechanism 300, which drives and connects to the blocking member 220. The lifting mechanism 300 includes at least one set of guide grooves 310 and connecting rods 320. The guide grooves 310 and connecting rods 320 guide the blocking member 220 to ensure that the blocking member 220 can move up and down along the direction of the guide grooves 310, thereby preventing lateral deviation or swaying.
[0045] exist Figure 2 In this embodiment, the guide groove 310 is provided extending in the vertical direction; the connecting rod 320 is slidably disposed in the guide groove 310, and one end is connected to the blocking member 220.
[0046] In some embodiments, if the connecting rod 320 is not connected to the drive device, the reset mechanism relies on the gravity of the blocking member 220 itself. For example, when the blocking member 220 needs to rise, it can be temporarily lifted by stacking waste materials; and after the waste materials are discharged, the blocking member 220 will naturally fall back to its original position by gravity.
[0047] In some embodiments, the cross-section of the storage section 210 is adapted to the shape of the blocking member 220, which can prevent waste from reaching above the blocking member 220, thus avoiding the problem of difficulty in removing waste above the blocking member 220. Figure 2 In this embodiment, when the storage section 210 is implemented as an elongated groove, the corresponding blocking member 220 is implemented as a blocking plate. If only one lifting mechanism 300 is used to drive one end of the blocking plate (such as the center position), the blocking plate may tilt during movement, especially when the blocking plate is long or subjected to uneven external forces. By setting two lifting mechanisms 300 to drive the left and right ends of the blocking plate respectively, it can be ensured that the blocking plate remains horizontal during up and down movement, avoiding jamming or movement failure due to tilting.
[0048] In one embodiment, the elastic member 330 can be directly connected to the blocking member 220. One end of the elastic member 330 is directly connected to the blocking member 220, and the other end is fixed to the guide groove 310. As an example, the elastic member 330 can also be in its natural state with one end abutting against the top of the blocking member 220 and the guide groove 310. When the blocking member 220 is lifted, the elastic member 330 is compressed; when the waste is cleaned up, the elastic member 330 gradually returns to its original shape, restoring the blocking member 220 to its initial position.
[0049] In another embodiment, the elastic element 330 is deformably disposed within the guide groove 310, driven by the upward movement of the connecting rod 320, so as to provide a downward restoring force applied to the connecting rod 320 during deformation.
[0050] You can refer to this. Figure 2 The elastic element 330 can also have one end corresponding to the connecting rod 320 and the other end corresponding to the top of the guide groove 310. When the connecting rod 320 moves upward, it can create pressure on one end of the elastic element 330, and the other end of the elastic element 330 can press against the top of the groove, thus compressing the elastic element 330. After the external driving force (the squeezing force of the waste accumulation on the blocking element 220) disappears, the elastic element 330 pushes the connecting rod 320 downward, causing the blocking element 220 to reset. The two ends of the elastic element 330 are not fixed, which facilitates installation.
[0051] In another embodiment, the two ends of the elastic member 330 can also be fixedly connected to the connecting rod 320 and the top of the guide groove 310, respectively. Compared with the embodiment where the two ends of the elastic member 330 are not fixedly connected, the elastic movement of the elastic member 330 is somewhat limited, and the reliability is somewhat increased.
[0052] As an example, guide groove 310 is as follows Figure 2 In the enlarged view at point F, the guide groove 310 has a stepped portion, and the end of the connecting rod 320 that mates with it has a locking portion 321. The locking portion 321 is blocked by the stepped portion, allowing the connecting rod 320 to disengage from the guide groove 310. In some embodiments, the elastic element 330 can also be implemented as a tension spring, which is disposed at both the stepped portion and the locking portion, and its two ends are fixedly connected to both. When the connecting rod 320 moves upward, the tension spring is stretched and deformed. When the external driving force is removed, the tension spring contracts, pulling the connecting rod 320 downward to complete the reset.
[0053] Optionally, the sensor 230 includes a contact sensor located at a preset position, configured to generate the trigger signal based on a contact signal from the blocking member 220. When the blocking member 220 moves to the preset position and makes physical contact with the contact sensor, the sensor 230 generates the trigger signal. Contact sensors have a simple structure, low cost, and high reliability. The contact sensor may include one of the following: a pressure sensor, a microswitch, or a mechanical switch.
[0054] Optionally, the sensor 230 includes a non-contact sensor, positioned relative to the blocking member 220 at a preset sensing distance. When the blocking member 220 enters the effective detection range of the sensor 230, the non-contact sensor generates a trigger signal without physical contact. Because there is no physical contact, the non-contact sensor reduces mechanical wear and extends the equipment's lifespan. The non-contact sensor may include, for example, a photoelectric sensor or a magnetic sensor (a corresponding magnet needs to be provided on the blocking member 220).
[0055] Optionally, a pair of sensors 230 may be provided, respectively located on opposite sides of the blocking member 220. Both sensors 230 simultaneously monitor changes in the position of the blocking member 220. Optionally, the purging action of the emission mechanism may be triggered only when both sensors 230 detect that the blocking member 220 has reached a predetermined position.
[0056] Optionally, the barrier 220 has an extension extending beyond the storage space, and the sensor 230 is positioned to sense the location of the extension. The extension serves as a sensing area, allowing the sensor 230 to accurately detect changes in the position of the barrier 220 without directly contacting the waste within the storage space.
[0057] Whether it's a non-contact or contact sensor, the position of the blocking element 220 can be monitored through the sensing extension. Since the sensor 230 does not directly contact the waste in the storage space, the risk of false triggering due to waste accumulation is reduced, thus improving the reliability of the system.
[0058] Optionally, in some embodiments, the waste output channel 100 includes a discharge channel, and the waste inlet 101 and waste outlet 102 are vertically offset. This offset design reduces the likelihood of waste accumulating directly at the outlet, avoiding blockages caused by concentrated waste. After entering the discharge channel from the inlet, the waste is pushed by subsequent waste due to the offset between the inlet and outlet, causing it to slide along the inner wall of the discharge channel and gradually move to the outlet position.
[0059] As an example, in Figure 4 In this embodiment, the other end of the discharge channel can be connected to a transition channel 110. The transition channel 110 and the discharge channel are inclined at a preset angle so that the stamping waste can be discharged at an angle along the transition channel 110. The transition channel 110 serves to guide the flow of waste and ensure that the waste can be discharged in a staggered manner.
[0060] Optionally, in Figure 2 In this embodiment, the blocking member 220 is also connected to a guide plate 250 along the discharge direction of the waste. The guide plate 250 forms a preset angle with the storage section 210 to guide the waste through the guide plate 250 and slide out of the main body 200. An appropriate tilt angle helps the waste slide out of the storage section 210 faster and more smoothly, reducing the time the waste stays in the storage space.
[0061] Optionally, the emission mechanism 240 is one of an air blowing mechanism, a suction mechanism, or a mechanical mechanism for moving waste.
[0062] As an example, the blowing mechanism uses high-speed airflow to propel waste in a designated direction, ultimately discharging the waste from the storage space. In some embodiments, the airflow speed and direction can be adjusted according to the characteristics of the waste (such as size, shape, and weight), making it highly adaptable.
[0063] As an example, the suction mechanism can be implemented as a vacuum pump, connected to the storage space via a pipe, to generate negative pressure to draw waste out of the storage space.
[0064] As an example, the mechanical mechanism that moves the waste directly through physical contact. For instance, a pusher device uses hydraulic or pneumatic pushers to move the waste, pushing it out of the storage space through periodic push-pull actions. A rotating brush at the waste outlet 102, driven by a motor, sweeps the waste away from the outlet. This method is effective for handling larger, heavier, or more viscous waste.
[0065] This disclosure also provides a stamping die device, which includes an upper die and a lower die that cooperate with each other to complete operations such as punching and forming of materials.
[0066] At least one of the upper and lower dies includes a punch, one end of which has a die opening for blanking, which is connected to a discharge channel. The die opening is the part of the punch used to cut or blank the workpiece. The die opening cuts off excess material through the blanking action to form the desired workpiece shape. The discharge channel guides the waste generated during blanking to a waste discharge device to prevent waste from accumulating in the die and affecting normal operation.
[0067] In any of the above embodiments, the waste discharge device is located in the mold where the punch is located, and its waste output channel 100 is connected to the end of the discharge channel away from the mold opening. As an example, the waste discharge device can be located in the upper mold.
[0068] The above embodiments are merely illustrative of the principles and effects of this disclosure and are not intended to limit this disclosure. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this disclosure. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this disclosure should still be covered by the protection scope of this disclosure.
