Description

Technical Field

[0001] This utility model relates to the technical field of terminal block production equipment, specifically to a device for processing metal sheet molds inside terminal blocks. Background Technology

[0002] In the manufacturing of terminal blocks, the internal metal sheet, as the core conductive component, has strict requirements for dimensional accuracy, structural strength, and processing efficiency. Traditional metal sheet processing often uses single-station stamping dies. The metal coil is fed into the die segment by segment by manual or semi-automatic feeding mechanism. After one stamping is completed, the machine needs to be stopped or slowed down to move and position the sheet before the next stamping operation.

[0003] This processing method has significant limitations: firstly, the intermittent nature of single-station operations leads to low production efficiency, making it difficult to meet the demands of large-scale mass production; secondly, the positioning accuracy of manual or semi-automatic feeding is limited, and metal sheets are prone to shifting during stamping, affecting not only product dimensional consistency but also potentially causing equipment damage due to mold misalignment. Furthermore, traditional stamping devices suffer from poor upper and lower die linkage, resulting in insufficient precision in controlling stamping pressure and timing, easily leading to quality defects such as deformation and cracks in the metal sheets. Simultaneously, the equipment lacks an effective synchronous detection and feedback mechanism, failing to promptly detect and adjust abnormalities during processing, further reducing production stability and finished product qualification rates. Utility Model Content

[0004] The purpose of this invention is to provide a terminal block internal metal sheet mold processing device that can achieve continuous synchronous processing, precise positioning, and a high degree of automation.

[0005] This utility model is achieved through the following technical solution: a metal sheet mold processing device for wiring terminals, including a frame, a pressure plate, a second synchronous belt, two first synchronous belts, multiple lower mold bases, and multiple stamping mechanisms;

[0006] Two first synchronous belts are arranged side by side in a horizontal direction and are located directly above the second synchronous belt. All three are in the same vertical plane, with gaps between adjacent synchronous belts for the metal coil to pass through. A power unit is installed on the frame to drive the second synchronous belt and the two first synchronous belts to move synchronously at the same linear speed. Multiple lower die holders are evenly distributed on the outer surface of the second synchronous belt. The lower die holders are fixedly connected to the second synchronous belt by second fixing rods. The side of the lower die holder facing the first synchronous belt has a die hole that matches the shape of the metal sheet. Multiple stamping mechanisms are evenly distributed on the outer surface of the first synchronous belt, corresponding one-to-one with the lower die holders. Each stamping mechanism includes an upper stamping head, a connecting plate, an elastic connecting assembly, and two first fixing rods. The two first fixing rods are respectively connected to the first synchronous belts on both sides. The outer surface of the belt is fixedly connected, and the connecting plate is horizontally connected between the two first fixed rods. The upper punch head is located on the side of the connecting plate facing the second synchronous belt and corresponds to the position of the die hole. The elastic connecting assembly includes a limiting plate, a guide rod and a spring. The guide rod moves through the connecting plate in a direction perpendicular to the connecting plate, and its two ends are fixedly connected to the upper punch head and the limiting plate, respectively. The spring is sleeved on the guide rod, and its two ends abut against the connecting plate and the limiting plate, respectively. The pressure plate is located on the inner side between the two first synchronous belts. Along the movement direction of the first synchronous belt, one end of the pressure plate is a horizontal section and the other end is an upwardly inclined guide section. The guide section is used to guide the limiting plate to smoothly enter the horizontal section. A cylinder is installed on the frame. The piston rod of the cylinder is fixedly connected to the pressure plate and is used to drive the pressure plate to rise and fall in the vertical direction.

[0007] The working principle of this technical solution is to achieve continuous stamping through the coordinated movement of synchronous belts. The two first and second synchronous belts are located on the same vertical plane and move synchronously at the same linear velocity, ensuring precise alignment between the upper stamping head and the lower die holder. The springs in the elastic connecting assembly buffer the stamping impact force, making the stamping process smoother; the guide section of the pressure plate guides the limiting plate smoothly into the horizontal section, ensuring orderly stamping action; and the cylinder drives the pressure plate to rise and fall, controlling the timing and force of the stamping.

[0008] To better realize this utility model, each of the stamping mechanisms has a permanent magnet installed on the outer surface of the first synchronous belt, and multiple permanent magnets are equidistantly distributed along the length of the first synchronous belt; a Hall sensor is installed on the frame at the starting position of the horizontal section of the pressure plate, and the Hall sensor is used to detect the position of the permanent magnet and trigger the cylinder to act.

[0009] To better realize this utility model, the power device further includes a servo geared motor, two first mounting shafts, four first synchronous pulleys, two second mounting shafts, two second synchronous pulleys, and a transmission assembly; the two first mounting shafts are parallel and horizontally rotatably mounted on the upper part of the frame, and the two second mounting shafts are parallel and horizontally rotatably mounted on the lower part of the frame, with the first mounting shafts and second mounting shafts corresponding vertically; the four first synchronous pulleys are respectively fixedly mounted at both ends of the two first mounting shafts, and the two first synchronous pulleys on the same side are connected by a corresponding first synchronous belt; the two second synchronous pulleys are respectively fixedly mounted in the middle of the two second mounting shafts, and the second synchronous belts are sleeved on the two second synchronous pulleys to form a transmission connection; the servo geared motor is fixedly mounted on the frame, and its output shaft is fixedly connected to one of the first mounting shafts or the second mounting shaft through a coupling; the first mounting shaft and the second mounting shaft are connected by a transmission assembly to achieve synchronous rotation of the two.

[0010] To better realize this utility model, the transmission assembly further includes a third mounting shaft, a third synchronous belt, two third synchronous pulleys, and two gears; the third mounting shaft is horizontally rotatably mounted on the frame and located between the first mounting shaft and the second mounting shaft; the two third synchronous pulleys are respectively fixedly mounted on one end of the first mounting shaft and the corresponding end of the third mounting shaft, and are connected by the third synchronous belt; the two gears are respectively fixedly mounted on the other end of the third mounting shaft and the corresponding end of the second mounting shaft, and mesh with each other; through the cooperation of the third synchronous belt and the gears, the rotation directions of the first mounting shaft and the second mounting shaft are opposite, and their linear velocities are the same.

[0011] To better realize this utility model, the limiting plate is further provided with a rotating shaft rotatably mounted on the side facing the pressure plate. The axis of the rotating shaft is set perpendicular to the direction of movement of the first synchronous belt, so as to form rolling friction when the limiting plate and the pressure plate come into contact.

[0012] To better realize this utility model, the two ends of the inner side of the frame are further fixedly connected with a first support rod and a second support rod; the first support rod is located below the first synchronous belt, and its top end is in rolling contact with the bottom of the first fixed rod, for supporting the first synchronous belt and the stamping mechanism; the second support rod is located above the second synchronous belt, and its top end is in rolling contact with the bottom of the lower die base, for supporting the second synchronous belt and the lower die base.

[0013] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0014] (1) This utility model uses the coordinated movement of two first synchronous belts and a second synchronous belt to drive the upper punch head and the lower die base to move synchronously. The metal coil can complete continuous punching operations during uninterrupted conveying, which completely changes the traditional single-station intermittent processing mode. The precise matching of the linear speeds of the three ensures a high degree of synchronization between the punching action and the feeding rhythm, significantly shortens the processing cycle, effectively increases the product output per unit time, and meets the needs of large-scale mass production;

[0015] (2) In this utility model, the lower die base and the upper punch head are one-to-one and evenly distributed, and the die holes and the punch head are precisely aligned. Combined with the stable guiding effect of the synchronous belt drive, the metal coil is not prone to displacement during the stamping process. At the same time, the first support rod and the second support rod provide effective support for the first and second synchronous belts respectively, avoiding positioning deviations caused by component deformation, ensuring the dimensional accuracy and structural consistency of the metal sheet, and reducing the scrap rate;

[0016] (3) The elastic connection component of this utility model buffers the impact of the stamping through the elastic force of the spring, making the pressure of the upper stamping head more gentle and controllable, effectively avoiding problems such as deformation and cracking of the metal sheet due to excessive force. The cylinder drives the pressure plate to rise and fall, and the stamping pressure can be adjusted according to the processing requirements of metal sheets of different specifications, further improving the stability of product quality, especially suitable for processing thin-walled precision metal sheets;

[0017] (4) In this utility model, the combination of the Hall sensor and the permanent magnet enables automatic detection and triggering of the stamping process. When the permanent magnet moves to the position of the Hall sensor along with the first synchronous belt, the sensor can accurately trigger the cylinder to act, controlling the pressure plate to press down in time to complete the stamping, without the need for manual operation. The servo-driven geared motor ensures the automated operation of the transmission system, reduces the intervention of manual feeding, positioning and other links, reduces labor costs, and avoids the impact of human operation errors on processing accuracy.

[0018] (5) The transmission assembly of this utility model achieves the reverse synchronous rotation of the first mounting shaft and the second mounting shaft through the combination of the third synchronous belt and the gear, ensuring the stability and durability of the synchronous belt drive. The rotating shaft on the limiting plate converts sliding friction into rolling friction, reducing the wear when the pressure plate contacts the limiting plate, reducing the wear rate of the components, and the overall structure is compact and the force is balanced. The coordinated cooperation of each component reduces local stress concentration and significantly improves the overall service life and operational reliability of the device.

[0028] Example 1:

[0029] The main structure of this embodiment is as follows: Figures 1-4 As shown, it includes a frame 1, a pressure plate 9, a second synchronous belt 51, two first synchronous belts 41, multiple lower die bases 2, and multiple stamping mechanisms;

[0030] Two first synchronous belts 41 are arranged side by side in the horizontal direction and are located directly above the second synchronous belt 51. All three are in the same vertical plane, and a gap is left between adjacent synchronous belts for the metal coil to pass through. A power device for driving the second synchronous belt 51 and the two first synchronous belts 41 to move synchronously at the same linear speed is installed on the frame 1. Multiple lower die bases 2 are evenly distributed on the outer surface of the second synchronous belt 51. The lower die bases 2 are fixedly connected to the second synchronous belt 51 by second fixing rods 20. The side of the lower die base 2 facing the first synchronous belt 41 has a die hole 201 that matches the shape of the metal sheet. Multiple stamping mechanisms are evenly distributed on the outer surface of the first synchronous belt 41, corresponding one-to-one with the lower die bases 2. The stamping mechanism includes an upper stamping head 3, a connecting plate 21, an elastic connecting assembly, and two first fixing rods 13. The two first fixing rods 13 are respectively fixed to the outer surface of the two first synchronous belts 41. The connection is as follows: the connecting plate 21 is horizontally connected between the two first fixed rods 13; the upper punch head 3 is located on the side of the connecting plate 21 facing the second synchronous belt 51 and corresponds to the position of the die hole 201; the elastic connecting assembly includes a limiting plate 14, a guide rod 16 and a spring 17; the guide rod 16 moves through the connecting plate 21 in a direction perpendicular to the connecting plate 21, and its two ends are fixedly connected to the upper punch head 3 and the limiting plate 14 respectively; the spring 17 is sleeved on the guide rod 16, and its two ends abut against the connecting plate 21 and the limiting plate 14 respectively; the pressure plate 9 is located on the inner side between the two first synchronous belts 41, along the movement direction of the first synchronous belts 41, one end of the pressure plate 9 is a horizontal section, and the other end is an upwardly inclined guide section, which is used to guide the limiting plate 14 to smoothly enter the horizontal section; a cylinder 10 is installed on the frame 1, and the piston rod of the cylinder 10 is fixedly connected to the pressure plate 9, which is used to drive the pressure plate 9 to rise and fall in the vertical direction.

[0031] The specific implementation process is as follows: First, the metal coil is inserted through the gap between adjacent synchronous belts. The power unit is started, causing the two first synchronous belts 41 and the second synchronous belt 51 to move synchronously at the same linear speed, and the metal coil is conveyed along with the synchronous belts. When the metal coil moves to above the die hole 201 of the lower die holder 2, it continues to move with the synchronous belt, and the upper punch head 3 gradually approaches. At the same time, the limiting plate 14 moves under the drive of the first synchronous belt 41 and smoothly enters the horizontal section through the guide section of the pressure plate 9. At this time, the cylinder 10 is started, and its piston rod pushes the pressure plate 9 down, squeezing the limiting plate 14. The limiting plate 14 drives the upper punch head 3 to move downward through the guide rod 16, punching the metal coil to form a matching workpiece at the die hole 201. After the punching is completed, the piston rod of the cylinder 10 drives the pressure plate 9 to rise, and the limiting plate 14 is reset under the action of the spring 17, and the upper punch head 3 leaves. With the movement of the synchronous belt, the upper punch head 3 and the lower die holder 2 repeat the above process to achieve continuous processing.

[0032] Example 2:

[0033] This embodiment further defines the structure of the stamping mechanism based on the above embodiments, such as... Figure 1 , Figure 2 As shown, a permanent magnet 12 is installed on the outer surface of the first synchronous belt 41 corresponding to each of the stamping mechanisms, and multiple permanent magnets 12 are equidistantly distributed along the length direction of the first synchronous belt 41; a Hall sensor 11 is installed on the frame 1 at the starting position of the horizontal section of the pressure plate 9, and the Hall sensor 11 is used to detect the position of the permanent magnet 12 and trigger the cylinder 10 to act.

[0034] Automatic stamping control is achieved by using Hall sensor 11 in conjunction with permanent magnet 12. Permanent magnet 12 moves with the first synchronous belt 41. When Hall sensor 11 detects permanent magnet 12, it indicates that the upper stamping head 3 and lower die holder 2 have reached the preset position, and then the cylinder 10 is triggered to act, thereby improving the degree of automation and ensuring accurate stamping timing.

[0035] The specific implementation process is as follows: when the first synchronous belt 41 drives the permanent magnet 12 to move, the Hall sensor 11 detects its position in real time. When the permanent magnet 12 moves to the position corresponding to the Hall sensor 11, the Hall sensor 11 sends a signal to trigger the cylinder 10 to act. The cylinder 10 drives the pressure plate 9 to descend, and drives the upper punch head 3 to punch through the limit plate 14 and guide rod 16. After completion, the cylinder 10 resets, and the spring 17 drives the upper punch head 3 and the limit plate 14 to reset. The first synchronous belt 41 continues to move, and when the next permanent magnet 12 approaches and the Hall sensor 11 detects it again, the punching is repeated, realizing automatic triggering and continuous operation. The other parts of this embodiment are the same as those in the above embodiment and will not be described again.

[0036] Example 3:

[0037] This embodiment further defines the structure of the power unit based on the above embodiments, such as... Figure 1 , Figure 2 As shown, the power unit includes a servo geared motor 7, two first mounting shafts 43, four first synchronous pulleys 42, two second mounting shafts 53, two second synchronous pulleys 52, and a transmission assembly. The two first mounting shafts 43 are parallel and horizontally rotatably mounted on the upper part of the frame 1, and the two second mounting shafts 53 are parallel and horizontally rotatably mounted on the lower part of the frame 1, with the first mounting shafts 43 and second mounting shafts 53 corresponding vertically. The four first synchronous pulleys 42 are respectively fixedly mounted at both ends of the two first mounting shafts 43, and the two first synchronous pulleys 42 on the same side are connected by a corresponding first synchronous belt 41. The two second synchronous pulleys 52 are respectively fixedly mounted in the middle of the two second mounting shafts 53, and the second synchronous belts 51 are sleeved on the two second synchronous pulleys 52 to form a transmission connection. The servo geared motor 7 is fixedly mounted on the frame 1, and its output shaft is fixedly connected to one of the first mounting shafts 43 or the second mounting shaft 53 through a coupling. The first mounting shafts 43 and the second mounting shafts 53 are connected by a transmission assembly to achieve synchronous rotation between them. The servo geared motor 7 provides power and, through the cooperation of the synchronous pulley, synchronous belt drive, and transmission components, enables the first mounting shaft 43 and the second mounting shaft 53 to rotate synchronously, ensuring that the linear speeds of the two first synchronous belts 41 and the second synchronous belt 51 are the same. The servo geared motor 7 has high precision and a wide speed range, ensuring stable and accurate synchronous belt movement.

[0038] The specific implementation process is as follows: The servo geared motor 7 is started, and its output shaft drives the connected first mounting shaft 43 or second mounting shaft 53 to rotate via a coupling. If the first mounting shaft 43 is driven, the first synchronous pulleys 42 at both ends rotate, driving the other first synchronous pulley 42 and the first mounting shaft 43 to rotate via the first synchronous belt 41, thus moving the two first synchronous belts 41. Simultaneously, the first mounting shaft 43 drives the second mounting shaft 53 to rotate via a transmission assembly. The second synchronous pulley 52 in the middle of the second mounting shaft 53 rotates, driving the other second synchronous pulley 52 and the second mounting shaft 53 to rotate via the second synchronous belt 51, thus moving the second synchronous belt 51. Due to the action of the transmission assembly, the two mounting shafts rotate synchronously, ensuring that the linear speed of the synchronous belts is the same. Other parts of this embodiment are the same as those in the above embodiment and will not be described again.

[0039] Example 4:

[0040] This embodiment further defines the structure of the transmission assembly based on the above embodiments, such as... Figure 1 , Figure 2As shown, the transmission assembly includes a third mounting shaft 22, a third synchronous belt 81, two third synchronous pulleys 82, and two gears 83. The third mounting shaft 22 is horizontally rotatably mounted on the frame 1 and located between the first mounting shaft 43 and the second mounting shaft 53. The two third synchronous pulleys 82 are respectively fixedly mounted at one end of the first mounting shaft 43 and the corresponding end of the third mounting shaft 22, and are connected by the third synchronous belt 81. The two gears 83 are respectively fixedly mounted at the other end of the third mounting shaft 22 and the corresponding end of the second mounting shaft 53, and mesh with each other. Through the cooperation of the third synchronous belt 81 and the gears 83, the first mounting shaft 43 and the second mounting shaft 53 rotate in opposite directions but have the same linear velocity. The transmission assembly, through the cooperation of the third synchronous belt 81, the third synchronous pulleys 82, and the gears 83, ensures that the first mounting shaft 43 and the second mounting shaft 53 rotate in opposite directions but have the same linear velocity. The third synchronous belt 81 can smoothly transmit power over long distances, and the meshing of the gears 83 ensures accurate transmission ratios, ensuring coordinated movement of the two mounting shafts and further guaranteeing synchronous movement of the synchronous belt.

[0041] The specific implementation process is as follows: the servo reduction motor 7 drives the first mounting shaft 43 to rotate, and the third synchronous pulley 82 at one end of the first mounting shaft 43 drives the corresponding third synchronous pulley 82 at the third mounting shaft 22 to rotate via the third synchronous belt 81, causing the third mounting shaft 22 to rotate. The gear 83 at the other end of the third mounting shaft 22 meshes with the corresponding gear 83 at the second mounting shaft 53, causing the second mounting shaft 53 to rotate. Because the third synchronous belt 81 and the gear 83 are engaged, the two mounting shafts rotate in opposite directions and have the same linear velocity, ensuring that the two first synchronous belts 41 and the second synchronous belt 51 move in opposite directions with the same linear velocity. Viewed vertically, this ensures that the upper punch head 3 and the lower die base 2 are precisely matched. The metal coil processing is the same as in the previous embodiment, and continuous stamping is completed under the synchronous movement of the synchronous belts. The other parts of this embodiment are the same as those in the above embodiment and will not be described again.

[0042] Example 5:

[0043] This embodiment, based on the above embodiment, further adds a rotating shaft 15, such as... Figure 3 As shown, a rotating shaft 15 is rotatably mounted on the side of the limiting plate 14 facing the pressure plate 9. The axis of the rotating shaft 15 is arranged perpendicular to the movement direction of the first synchronous belt 41, and is used to generate rolling friction when the limiting plate 14 and the pressure plate 9 come into contact. The rotating shaft 15 on the limiting plate 14 converts the sliding friction between the limiting plate 14 and the pressure plate 9 into rolling friction. Rolling friction is less than sliding friction, which can reduce wear when the two are in contact, extend the service life of the components, and at the same time make the movement of the limiting plate 14 on the pressure plate 9 smoother, ensuring stamping stability.

[0044] The specific implementation process is as follows: the basic processes of metal coil insertion, synchronous belt start-up, and stamping are the same as in Example 1. When the limiting plate 14 moves under the drive of the first synchronous belt 41 and contacts the pressure plate 9, the rotating shaft 15 on the limiting plate 14 contacts the pressure plate 9. As the limiting plate 14 moves, the rotating shaft 15 rolls on the pressure plate 9, realizing friction conversion. This allows the limiting plate 14 to pass through the guide section and enter the horizontal section more smoothly, reducing friction loss, ensuring the smooth movement of the upper stamping head 3, and improving the stamping quality. After stamping is completed, the limiting plate 14 is reset under the action of the spring 17, and the rotating shaft 15 moves with it, preparing for the next stamping. The other parts of this embodiment are the same as those in the above embodiments and will not be described again.

[0045] Example 6:

[0046] This embodiment, based on the above embodiment, further adds a first support rod 18 and a second support rod 19, such as... Figure 1 , Figure 2 As shown, a first support rod 18 and a second support rod 19 are fixedly connected to both ends of the inner side of the frame 1. The first support rod 18 is located below the first synchronous belt 41, and its top end is in rolling contact with the bottom of the first fixed rod 13, serving to support the first synchronous belt 41 and the stamping mechanism. The second support rod 19 is located above the second synchronous belt 51, and its top end is in rolling contact with the bottom of the lower die holder 2, serving to support the second synchronous belt 51 and the lower die holder 2. The first support rod 18 and the second support rod 19 respectively support the first synchronous belt 41 and the stamping mechanism, and the second synchronous belt 51 and the lower die holder 2. During stamping, the stamping mechanism and the lower die holder 2 are subjected to pressure. The support rods can prevent the synchronous belt from deforming under force, ensuring the positional accuracy of the upper stamping head 3 and the lower die holder 2, and ensuring accurate and stable stamping.

[0047] The specific implementation process is as follows: During stamping, the pressure plate 9 presses against the limiting plate 14, causing the upper stamping head 3 to stamp downwards. The first support rod 18 supports the first fixed rod 13, bearing the pressure of the stamping mechanism and preventing the first synchronous belt 41 from sinking and deforming. At the same time, the lower die base 2 bears the stamping pressure, and the second support rod 19 supports it, preventing the second synchronous belt 51 from deforming and ensuring the stability of the die hole 201. Through the action of the two support rods, it is ensured that the upper stamping head 3 and the lower die base 2 are always precisely aligned, improving stamping accuracy and quality, reducing synchronous belt wear, and extending the life of the device. The other parts of this embodiment are the same as those in the above embodiment and will not be described again.
