Description

Technical Field

[0001] The invention relates to the technical field of metal stamping, in particular to a stamping die for stable hardware processing. Background Art

[0002] In the prior art, a stamping die is a metal stamping tool consisting of an upper and lower die. The kinetic energy is applied by a press to cause the metal sheet to undergo plastic deformation or separation in the die cavity, and hardware parts are manufactured in batches. Its core function is to achieve efficient and precise punching, bending or stretching processing, and it is widely used in the fields of automobiles, electronics, etc. In the process of hardware processing, the corresponding control system is usually used in combination. In daily use, there are often mechanical damage and physical damage, such as excessive vibration, impact, and harsh environmental conditions such as high temperature, low temperature, and humidity, which affect the performance of the sensor. If the sensor of the control system fails, the algorithm is inaccurate, or the operator does not set the parameters correctly, the system will not be able to accurately control the stamping speed, causing it to accelerate abnormally during the processing process, which not only affects the quality of the hardware, but also damages the mold and equipment, increases production costs and safety risks. However, the feedback of traditional stamping molds on the stamping speed often relies on complex sensor systems, and these sensor systems often have errors or failures, resulting in inaccurate feedback on the stamping speed, which makes it easy for staff to misjudge, thereby affecting the stamping quality and production efficiency of the hardware. In the subsequent stamping process, if the stamping speed is maintained too fast for a long time, it will not only cause deformation and damage to the hardware, but also impact the mold itself, shorten the service life of the mold, and even cause safety accidents.

[0008] Preferably, a mounting plate is fixedly connected to the top of the base, and the mounting plate, passive plate and touch plate are all arranged on the same horizontal line, the passive plate is arranged between the touch plate and the mounting plate, and the passive plate and touch plate are both slidably connected to the upper surface of the base.

[0009] Preferably, an elastic buffer column is fixedly connected to a side of the mounting plate facing the touch panel, and an end of the elastic buffer column away from the mounting plate is fixedly connected to the passive board.

[0010] Preferably, the anti-blocking and unblocking mechanism also includes a bidirectional synchronous motor fixedly connected to the inner top wall of the base, L-shaped support plates are symmetrically fixedly connected on both sides of the base, bidirectional reciprocating screws are symmetrically rotatably connected between the L-shaped support plates, and one side of the bidirectional reciprocating screw is symmetrically fixedly connected to the output ends of both sides of the bidirectional synchronous motor, and a transmission part is connected between the bidirectional reciprocating screws.

[0011] Preferably, the linkage frame is slidingly connected to the inner top wall of the base, the linkage frame is symmetrically threadedly connected to the outer surface of the bidirectional reciprocating screw, the outer surface of the linkage frame is fixedly connected to a guide plate, the guide plate is used to guide and transport the waste generated by stamping, the ends of the guide plates that are close to each other are set to an inclined shape, and the upper surface of the inclined end of the guide plate is fixedly connected to a dividing strip, and the dividing strip is used to divide the guide area on the upper surface of the inclined end of the guide plate.

[0014] Preferably, the connecting rod is used to control the height of the clearing frame, and the clearing frame is used to clear the mold holes opened on the lower mold. A protective cover is also fixedly connected to the bottom of the base.

[0015] Compared with the prior art, the present invention has the following beneficial effects: (1) By setting up the stamping feedback mechanism and utilizing the linkage of the guide sleeve, guide column and L-shaped piston cylinder, the stamping speed of the equipment can be converted into the actual displacement of the touch plate, thereby realizing real-time visual monitoring of the stamping speed and establishing a direct and clear relationship between the moving range of the touch plate and the stamping speed. When using the equipment, the staff only needs to observe the position of the touch plate to judge the current operating status of the equipment, thereby greatly simplifying the monitoring process and reducing the dependence on complex sensors. When the stamping speed of the equipment is too fast, the touch plate will move and contact the contact points on the passive plate, thereby triggering the alarm. This design not only reminds the staff to pay attention to potential safety issues, but also automatically shuts down the main power supply of the equipment to prevent equipment damage or personal injury caused by excessive stamping speed. Among them, the elastic buffer column designed between the passive board and the mounting plate is used to give the passive board additional flexibility, so that when the touch panel moves and contacts it, it can effectively absorb the impact energy caused by the touch panel through flexible contact, reducing the risk of rigid collision between the touch panel and the contact point, thereby effectively avoiding damage to the mechanical structure due to instantaneous overload, thereby improving the overall safety of the equipment and extending the service life of the overall mechanical mechanism.

[0016] (2) By setting up the anti-blocking and unblocking mechanism and using the bidirectional reciprocating screw to drive the linkage frame, combined with the design of the connecting rod, the two guide plates can be moved in opposite directions to expand when the main power of the equipment is turned off, and the unblocking frame can be driven to be inserted into the mold hole opened on the lower mold to push the metal waste left inside the mold hole and causing blockage. As the bidirectional reciprocating screw continues to rotate, the two linkage frames can be driven to move toward each other, so that the unblocking frame is withdrawn from the mold hole, and the loosened metal waste falls out of the mold hole synchronously, thereby unblocking the mold hole and avoiding the metal waste in the mold hole from getting stuck or falling smoothly, causing excessive waste to pile up in the hole and affecting the subsequent normal stamping of the hardware. In addition, the linkage between the structures can realize the automatic movement and unblocking of the unblocking frame, so that there is no need for manual intervention to unblock the waste in the mold hole, thereby improving the production efficiency.

[0017] (3) Through the setting of the anti-blocking and dredging mechanism, when the equipment is in use, two guide plates close to each other are used, and the guide plates are inclined, and the adjacent inclined ends are set at high positions. When the hardware is stamped, the hardware waste formed by the hardware can be diverted and discharged to both sides in an orderly manner through the guide plates, thereby ensuring the smooth discharge of the waste, and allowing these hardware wastes to eventually fall into the collection box for collection; Among them, the inclined design of the guide plate can divide the upper surface of the inclined end of the guide plate into unloading areas in sequence by cooperating with the dividing strip to form a directional slideway, thereby increasing the dispersion of the hardware waste in the process of diversion and discharge of the hardware waste, further ensuring the smoothness of the waste discharge, and avoiding the problem of waste contacting each other and accumulating to cause secondary blockage.

When the contact 609 is touched to activate the alarm, the main power supply of the equipment is simultaneously turned off to stop stamping the hardware to reduce losses.

[0023] The effects achieved by this embodiment are as follows: compared with the prior art, by setting the stamping feedback mechanism 6 and utilizing the linkage of the guide sleeve 4, the guide column 5 and the L-shaped piston cylinder 602, the stamping speed of the equipment can be converted into the actual displacement of the touch plate 605, thereby not only realizing real-time visual monitoring of the stamping speed, but also establishing a direct and clear relationship between the moving range of the touch plate 605 and the stamping speed, so that the staff only needs to observe the position of the touch plate 605 to judge the current operating status of the equipment when using it, thereby greatly simplifying the monitoring process and reducing the dependence on complex sensors, and when the stamping speed of the equipment is too fast, the touch plate 605 will move and contact the contact 609 on the passive plate 608, thereby triggering the alarm. This design not only reminds the staff to pay attention to potential safety issues, but also automatically shuts down the main power supply of the equipment to prevent equipment damage or personal injury caused by excessive stamping speed; Among them, the elastic buffer column 607 designed between the passive plate 608 and the mounting plate 606 is used to give the passive plate 608 additional flexibility, so that when the touch plate 605 moves and contacts it, it can effectively absorb the impact energy caused by the touch plate 605 through flexible contact, thereby reducing the risk of rigid collision between the touch plate 605 and the contact point 609, thereby effectively avoiding damage to the mechanical structure due to instantaneous overload, thereby improving the overall safety of the equipment and extending the service life of the overall mechanical mechanism.

[0024] Embodiment 2 of the present invention: Please refer to Figures 1 to 6 As shown, the anti-blocking and dredging mechanism 7 also includes a bidirectional synchronous motor 702 fixedly connected to the inner top wall of the base 1, and L-shaped support plates 701 are symmetrically fixedly connected on both sides of the base 1. A bidirectional reciprocating screw rod 703 is symmetrically rotatably connected between the L-shaped support plates 701, and one side of the bidirectional reciprocating screw rod 703 is symmetrically fixedly connected to the output ends of the bidirectional synchronous motor 702 on both sides, and a transmission member 704 is transmission-connected between the bidirectional reciprocating screw rods 703; The linkage frame 705 is slidably connected to the inner top wall of the base 1, and the linkage frame 705 is symmetrically threadedly connected to the outer surface of the bidirectional reciprocating screw 703. The outer surface of the linkage frame 705 is fixedly connected with a guide plate 706, and the guide plate 706 is used to guide and transport the waste generated by stamping. The ends of the guide plates 706 that are close to each other are all set to be inclined, and the upper surface of the inclined end of the guide plate 706 is fixedly connected with a partition bar 707, and the partition bar 707 is used to divide the upper surface of the inclined end of the guide plate 706 into a guide area; A collecting box 708 is slidably connected to the bottom of one end of the guide plate 706 facing the linkage frame 705, and the collecting box 708 is used to collect the waste guided and transported by the guide plate 706; The outer surface of the linkage frame 705 is also fixedly connected to a connecting frame 709, the bottom of the clearing frame 712 is fixedly connected to a connecting plate 711, and both ends of the connecting rod 710 are rotatably connected to the connecting plate 711 and the connecting frame 709 respectively; The connecting rod 710 is used to control the height of the clearing frame 712. The clearing frame 712 is used to clear the mold holes opened on the lower mold 2. A protective cover 713 is also fixedly connected to the bottom of the base 1.

[0025] Please refer to Figure 3 , preferably: the bidirectional synchronous motor 702 is electrically connected to the main power supply of the stamping equipment. When the main power supply of the stamping equipment is turned off, the bidirectional synchronous motor 702 starts to start, and the mold hole opened on the lower mold 2 is cleared by the clearing frame 712 (it should be noted that the triggering condition of the bidirectional synchronous motor 702 here is that whether the main power supply of the equipment is normally turned off or the contact 609 is turned off due to being touched, the start-up operation of the bidirectional synchronous motor 702 is triggered); In addition, a bidirectional reciprocating screw rod 703 is fixedly arranged at both output ends of the bidirectional synchronous motor 702, and the opposite ends of the bidirectional reciprocating screw rod 703 connected to the bidirectional synchronous motor 702 are respectively rotatably connected to the two L-shaped support plates 701. In addition, a bidirectional reciprocating screw rod 703 is rotatably connected between the two L-shaped support plates 701, and the linkage frame 705 is connected according to Figure 3 As shown, the symmetrical sliding is arranged at the bottom of the base 1, and the linkage frame 705 is slidably connected to the outer surface of the bidirectional reciprocating screw rod 703. When the bidirectional synchronous motor 702 starts to run, the bidirectional reciprocating screw rod 703 rotates on the L-shaped support plate 701, and through the threaded connection, the two linkage frames 705 can be driven to move toward or away from each other; according to Figure 3As shown, the bidirectional reciprocating screw rods 703 are connected to each other by a transmission member 704, which is composed of two transmission wheels and a transmission belt connected between the two transmission wheels, and the transmission wheels are respectively fixed on the bidirectional reciprocating screw rods 703 on both sides. When the bidirectional synchronous motor 702 drives the bidirectional reciprocating screw rod 703 on one side to rotate, the transmission action of the transmission member 704 can drive the bidirectional reciprocating screw rod 703 on the other side to rotate synchronously.

[0026] The effects achieved by this embodiment are as follows: by setting up the anti-blocking and unblocking mechanism 7, using the bidirectional reciprocating screw rod 703 to drive the linkage frame 705, and cooperating with the design of the connecting rod 710, the two guide plates 706 can be moved back to back to be unfolded when the main power of the equipment is turned off, and the clearing frame 712 is driven to be inserted into the mold hole opened on the lower mold 2, and the hardware waste left inside the mold hole that causes the blockage is pushed, and as the bidirectional reciprocating screw rod 703 continues to rotate, the two linkage frames can be driven to move. 705 move toward each other, so that the clearing rack 712 withdraws from the die hole, and the loosened hardware waste falls out of the die hole synchronously, thereby achieving the unblocking of the die hole, avoiding the hardware waste in the die hole from getting stuck and falling poorly, causing excessive waste accumulation in the hole and affecting the subsequent normal stamping of the hardware. In addition, the linkage between the structures can realize the automatic movement and unblocking of the clearing rack 712, so that there is no need for manual intervention to unblock the waste in the die hole, thereby improving the production efficiency; In addition, by setting the anti-blocking and unblocking mechanism 7, when the equipment is used, two guide plates 706 close to each other are used, and the guide plates 706 are inclined, and the adjacent inclined ends are set at high positions. When the hardware is stamped, the hardware waste formed by the hardware can be orderly diverted and discharged to both sides through the guide plates 706, thereby ensuring the smooth discharge of the waste, and allowing these hardware wastes to eventually fall into the collection box 708 for collection; Among them, the inclined design of the guide plate 706 can divide the upper surface of the inclined end of the guide plate 706 into unloading areas in sequence by cooperating with the dividing strip 707, thereby increasing the dispersion of the hardware waste in the process of diverting and exporting the hardware waste, further ensuring the smoothness of the waste discharge, and avoiding the problem of waste contacting each other and accumulating to cause secondary blockage.

[0027] The complete usage steps and working principle of the above embodiment are as follows: The following is the working process of the stamping feedback mechanism 6 providing real-time feedback on the stamping speed of the stamping part 3: When in use, the hardware is placed on the upper surface of the lower die 2. Through the downward movement of the stamping part 3, in conjunction with the die holes opened on the lower die 2, the hardware can be stamped. During the stamping process, Figure 1 and Figure 2 As shown, since guide sleeves 4 and guide posts 5 that are slidably connected to each other are arranged at the four corners between the stamping part 3 and the base 1, and the guide sleeve 4 is fixedly connected to the stamping part 3, and the guide post 5 is fixedly connected to the base 1, and a first piston rod 601 is fixedly arranged on the outer surface of one of the guide sleeves 4, when the stamping part 3 descends to stamp the hardware, the guide sleeve 4 slides downward synchronously with the outer surface of the guide post 5, and drives the first piston rod 601 installed on the outer surface of the guide sleeve 4 to move downward synchronously, according to Figure 1 As shown, an L-shaped piston cylinder 602 is fixedly arranged on the upper surface of the base 1, and the upper end of the L-shaped piston cylinder 602 is slidably connected with the first piston rod 601. Therefore, when the guide sleeve 4 cooperates with the first piston rod 601 to move downward, the first piston rod 601 can move downward synchronously in the L-shaped piston cylinder 602. Figure 2 As shown, a second piston rod 603 is slidably connected to the end of the L-shaped piston cylinder 602 away from the first piston rod 601, and a touch plate 605 is fixedly arranged at the end of the second piston rod 603 away from the L-shaped piston cylinder 602. When the first piston rod 601 moves downward, the second piston rod 603 can be pushed to move outward in the L-shaped piston cylinder 602. At this time, the touch plate 605 arranged at the end of the second piston rod 603 follows synchronously and slides on the upper surface of the base 1 toward the passive plate 608. When the stamping speed is not too fast, the moving range of the touch plate 605 is small and cannot contact the passive plate 608. When the stamping speed is too fast, the moving range of the touch plate 605 increases and contacts the passive plate 608. like Figure 2 As shown, since the passive plate 608 and the touch plate 605 are both slidably arranged on the base 1, and the passive plate 608 and the touch plate 605 are arranged oppositely, and the passive plate 608 is provided with a contact 609 on the side of the touch plate 605, when the stamping speed is too fast and the touch plate 605 and the passive plate 608 are pushed to form contact, the touch plate 605 will preferentially contact the contact 609, and an alarm electrically connected to the contact 609 is fixedly installed on the base 1. When the contact 609 is touched, the alarm will be turned on to remind nearby staff that there is a problem of excessive stamping speed at that place and timely response is required, thereby not only achieving real-time feedback on the stamping results, so that the staff can understand the stamping speed of the equipment according to the push-out situation of the touch plate 605, but also can respond in time when the problem of excessive stamping speed occurs, thereby effectively reducing the failure rate of the equipment and the unqualified rate of the finished hardware stamping products; Furthermore, the contact 609 is electrically connected to the alarm and the main power supply of the stamping equipment. When the stamping speed is too fast and the touch plate 605 touches the contact 609, not only the alarm is activated, but also the main power supply of the equipment can be turned off synchronously to stop the stamping of the hardware, so as to avoid the staff failing to handle it in time and affecting the overall stamping quality of the hardware. Among them, Figure 2 As shown, since a return spring 604 is fixedly arranged between the L-shaped piston cylinder 602 and the touch plate 605, and the return spring 604 is sleeved on the outside of the second piston rod 603, when the first piston rod 601 moves downward to drive the second piston rod 603 to move outward in the L-shaped piston cylinder 602, the return spring 604 can be stretched by the pulling action of the touch plate 605. When the stamping action is completed and the ascending action is performed, the first piston rod 601 moves in the opposite direction, moves upward in the L-shaped piston cylinder 602, and drives the second piston rod 603 to move in the opposite direction in the L-shaped piston cylinder 602, that is, when it moves in the direction away from the passive plate 608, the tension on the return spring 604 disappears and it will shrink synchronously. The design of the return spring 604 can make the pushing motion of the second piston rod 603 more stable. When the stamping action is completed, the return spring 604 will help the second piston rod 603 return to its initial position to prepare for the next stamping action. This stability helps to ensure the long-term reliable operation of the mechanism. In addition, according to Figure 2 As shown, an elastic buffer column 607 is fixedly arranged on one side of the passive plate 608 away from the touch plate 605, and the other end of the elastic buffer column 607 is fixedly connected to the mounting plate 606, and the mounting plate 606 is fixedly arranged on the upper surface of the base 1. When the stamping speed of the equipment is too fast, the touch plate 605 slides on the upper surface of the base 1 and finally touches the passive plate 608. At this time, due to the instability of the stamping speed, the design of the elastic buffer column 607 enables the contact 609 to increase the flexibility. When facing the touch of the touch plate 605, it can be combined with the rigid push of the touch plate 605 to make the passive plate 608 slide synchronously on the upper surface of the base 1, thereby avoiding the situation that the touch plate 605 pushes the passive plate 608 excessively when the stamping speed is too fast, causing damage to the contact 609, thereby realizing the buffer design of the contact 609 structure and extending the service life of the contact 609 structure; In the above process, by setting the stamping feedback mechanism 6 and utilizing the linkage of the guide sleeve 4, the guide column 5 and the L-shaped piston cylinder 602, the stamping speed of the equipment can be converted into the actual displacement of the touch plate 605, thereby not only realizing real-time visual monitoring of the stamping speed, but also establishing a direct and clear relationship between the moving range of the touch plate 605 and the stamping speed, so that the staff only needs to observe the position of the touch plate 605 to judge the current operating status of the equipment during use, thereby greatly simplifying the monitoring process and reducing the dependence on complex sensors. When the stamping speed of the equipment is too fast, the touch plate 605 will move and contact the contact 609 on the passive plate 608, thereby triggering the alarm. This design not only reminds the staff to pay attention to potential safety issues, but also automatically shuts down the main power supply of the equipment to prevent equipment damage or personal injury caused by excessive stamping speed. Among them, the elastic buffer column 607 designed between the passive plate 608 and the mounting plate 606 is used to give the passive plate 608 additional flexibility, so that when the touch plate 605 moves and contacts it, it can effectively absorb the impact energy caused by the touch plate 605 through flexible contact, reducing the risk of rigid collision between the touch plate 605 and the contact point 609, thereby effectively avoiding damage to the mechanical structure due to instantaneous overload, thereby improving the overall safety of the device and extending the service life of the overall mechanical mechanism; Please refer to the above working process Figures 1 to 6 .

[0028] The following is the working process of the anti-blocking and unblocking mechanism 7 unblocking the mold hole opened on the lower mold 2: It should be noted that the die hole opened on the lower die 2 is opened on the base 1 simultaneously, so that the subsequent clearing frame 712 structure penetrates the base 1 and is inserted into the die hole opened on the lower die 2 to push the hardware waste remaining from the stamping inside the die hole, so as to avoid the waste from accumulating inside the die hole and affecting the subsequent stamping process, so as to reduce the overall quality of the hardware stamped out later; like Figure 3 As shown, L-shaped support plates 701 are symmetrically fixedly arranged on both sides of the base 1, a bidirectional synchronous motor 702 is fixedly arranged on the inner top wall of the base 1, and bidirectional reciprocating screw rods 703 are fixedly arranged between the output ends on both sides of the bidirectional synchronous motor 702 and the adjacent L-shaped support plates 701. At the same time, the bidirectional synchronous motor 702 is electrically connected to the main power supply of the stamping equipment. When the main power supply of the stamping equipment is turned off, the bidirectional synchronous motor 702 starts to run, and the mold hole opened on the lower mold 2 is cleared by the clearing frame 712 (it should be noted that the triggering condition of the bidirectional synchronous motor 702 here can trigger the start-up of the bidirectional synchronous motor 702 regardless of whether the main power supply of the equipment is normally turned off or the contact 609 is turned off due to being touched); like Figure 3 As shown, a bidirectional reciprocating screw rod 703 is synchronously rotated between the L-shaped support plate 701 and away from the bidirectional synchronous motor 702, and a transmission member 704 is connected between the bidirectional reciprocating screw rods 703 on both sides. For details, please refer to Figure 3The transmission member 704 is composed of two transmission wheels and a transmission belt connected between the two transmission wheels, and the transmission wheels are fixedly arranged on the two-way reciprocating screw rods 703 on both sides. When the two-way synchronous motor 702 drives the two-way reciprocating screw rod 703 on one side to rotate, the transmission effect of the transmission member 704 can drive the two-way reciprocating screw rod 703 on the other side to rotate synchronously. Since a linkage frame 705 is symmetrically threaded between the two-way reciprocating screw rods 703 on both sides, when the two-way reciprocating screw rods 703 rotate, the two linkage frames 705 can be synchronously driven to move in opposite directions by means of threaded connection. Figure 4 , Figure 5 as well as Figure 6 , a guide plate 706 is fixedly arranged on the linkage frame 705, and the end of the guide plates 706 close to each other is arranged in an inclined shape, and the guide plate 706 is arranged below the base 1. When the hardware is stamped, the stamped hardware waste can fall vertically downward from the mold hole opened on the lower mold 2, pass through the base 1, and finally fall to the upper surface of the guide plate 706. The inclined design can make the fallen hardware waste be diverted and discharged to both sides. Because a dividing strip 707 is fixedly arranged on the upper surface of the inclined end of the guide plate 706, the upper surface of the inclined end of the guide plate 706 can be divided into areas, so that the areas are aligned with the mold holes, so as to facilitate the mold to be discharged one by one according to the divided areas, thereby avoiding mutual contact and collision between the waste materials, and stacking on the guide plate 706, so that the discharge of the waste materials can be more orderly and smooth, and a slidingly connected collection box 708 is arranged below the end of the guide plate 706 away from each other, such as Figure 6 As shown, when the guide plate 706 guides and discharges the hardware waste, the hardware waste can eventually fall into the inside of the collection box 708 due to the inclined design of the guide plate 706, and the waste is collected accordingly; Because the linkage frame 705 is also fixedly provided with a connecting frame 709, a clearing frame 712 is provided below the guide plate 706, and a connecting plate 711 is fixedly provided at the bottom of the clearing frame 712, and a connecting rod 710 is rotatably provided between the connecting plate 711 and the connecting frame 709, so that when the two linkage frames 705 move in opposite directions, not only can the guide plate 706 installed thereon move outward synchronously, but also the connecting frame 709 can synchronously follow the linkage frame 705 to move horizontally below the base 1, and cooperate with the connecting rod 710 to make the connecting plate 711 and the clearing frame 712 move upward synchronously, that is, toward the location of the base 1. The two-way reciprocating screw rod 703 is rotated in a direction close to each other, so that the clearing frame 712 can finally penetrate the corresponding mold hole on the base 1 and be inserted into the mold hole on the lower mold 2, so as to push the metal waste left inside the mold hole and causing the blockage. With the continuous rotation of the two-way reciprocating screw rod 703, the two linkage frames 705 can be driven to move toward each other, so that the clearing frame 712 is withdrawn from the mold hole, and the loosened metal waste is synchronously dropped out of the mold hole, thereby achieving the unblocking of the mold hole, avoiding the metal waste in the mold hole from getting stuck and falling poorly, causing the waste to pile up too much in the hole and affecting the subsequent normal stamping of the hardware. When the clearing frame 712 exits the die hole, the linkage frame 705 moves toward each other, so that the guide plate 706 can be reset to collect the hardware waste that falls through the die hole during subsequent stamping. The sliding design of the collection box 708 can facilitate the removal of the waste, and the collected waste can be subsequently recycled and processed. Figure 1 As shown, a protective cover 713 is provided at the lower end of the base 1, which can protect the various structures in the anti-blocking and dredging mechanism 7 to avoid structural damage caused by collision, thereby effectively extending the service life of the mechanism and facilitating the subsequent stamping work of the hardware; In the above process, by setting the anti-blocking and unblocking mechanism 7, the two-way reciprocating screw 703 drives the linkage frame 705, and cooperates with the design of the connecting rod 710, when the main power of the equipment is turned off, the two guide plates 706 can be moved back to each other for expansion, and the unblocking frame 712 is driven to be inserted into the mold hole opened on the lower mold 2, and the hardware waste left inside the mold hole and causing the blockage is pushed. As the two-way reciprocating screw 703 continues to rotate, the two linkage frames 705 can be driven to move toward each other, so that the unblocking frame 712 withdraws from the mold hole, and the loosened hardware waste falls out of the mold hole synchronously, thereby realizing the unblocking of the mold hole, avoiding the hardware waste in the mold hole from getting stuck and falling poorly, causing the waste to pile up too much in the hole and affecting the subsequent normal stamping of the hardware. In addition, the linkage between the structures can realize the automatic movement and unblocking of the unblocking frame 712, so that there is no need for manual intervention to unblock the waste in the mold hole, thereby improving the production efficiency. In addition, by setting the anti-blocking and unblocking mechanism 7, when the equipment is used, two guide plates 706 close to each other are used, and the guide plates 706 are inclined, and the adjacent inclined ends are set at high positions. When the hardware is stamped, the hardware waste formed by the hardware can be orderly diverted and discharged to both sides through the guide plates 706, thereby ensuring the smooth discharge of the waste, and allowing these hardware wastes to eventually fall into the collection box 708 for collection; Among them, the inclined design of the guide plate 706 can be used to divide the upper surface of the inclined end of the guide plate 706 into unloading areas in sequence to form a directional slideway by cooperating with the dividing strip 707, so that in the process of diverting and exporting the hardware waste, the dispersion of the hardware waste can be increased, and the smoothness of the waste discharge can be further ensured, and the problem of secondary blockage caused by the contact and accumulation of the waste can be avoided; Please refer to the above working process Figures 1 to 6 .
