Description

Technical Field

[0001] This utility model relates to the field of terminal block processing technology, specifically to a device for stamping metal sheets inside a terminal block. Background Technology

[0002] As a key component in electrical connections, the stamping quality of the internal metal sheets of terminal blocks directly affects the stability and reliability of these connections. Currently, traditional stamping equipment faces several problems in the metal sheet stamping process for terminal blocks. Some existing equipment uses a single conveyor belt for feeding, where the metal sheets are susceptible to their own rigidity and conveyor belt vibration during transport, leading to positional shifts, unevenness, or even loosening, resulting in stamping misalignment and significantly reducing stamping accuracy and yield. Existing positioning methods are mostly simple fixed blocks or single clamping plates, which are insufficient to meet the precise positioning requirements of metal sheets of different specifications. Even slight changes in the metal sheet size cannot guarantee its straightness and positional accuracy during stamping, resulting in large dimensional deviations in the stamped products and failing to meet increasingly stringent electrical performance requirements. Furthermore, mold changes are cumbersome. The metal sheets inside terminal blocks come in various shapes, requiring frequent mold changes when producing different specifications. However, the connection between the lower die base and the operating table in traditional stamping equipment is complex, and the locking structure is inconvenient to operate. Each mold change consumes a significant amount of time and manpower, increasing production costs and reducing production efficiency. Utility Model Content

The two support plates are respectively in sliding contact with the bottom surface of the support end of the first conveyor belt and the second conveyor belt.

[0010] To better realize this utility model, a positioning channel is further formed between the first conveyor belt and the second conveyor belt. Two clamping plates that are symmetrically connected to the operating table are arranged in the positioning channel.

[0014] Compared with the prior art, this utility model has the following advantages and beneficial effects: (1) This utility model provides stable conveying support for the metal plate by setting a first conveyor belt and a second conveyor belt. At the same time, the two pressure rollers at the bottom of the pressure plate, which can only rotate unidirectionally along the conveying direction of the metal sheet, work with the tensioning assembly to drive the first rotating shaft to rotate, thereby realizing the precise segmented pushing of the metal plate. The unidirectional rotation characteristic of the pressure rollers can effectively prevent the metal plate from rebounding, while the tensioning assembly ensures the tension of the movable frame, ensuring that the pressure rollers and the metal plate always maintain good contact, reducing the vertical vibration of the metal plate during the conveying process, thereby reducing the probability of stamping deviation and improving product quality; (2) In this utility model, two clamping plates are symmetrically arranged in the positioning channel formed between the first conveyor belt and the second conveyor belt. The guide wheels on the clamping plates can roll with the metal plate during conveying, reducing friction. The bidirectional module can drive the clamping plates on both sides to move closer or further away synchronously along the direction perpendicular to the conveying direction of the metal sheet. It can be adjusted according to different specifications of metal plates to ensure that the metal plate maintains good straightness during conveying, which provides a guarantee for precise stamping and further improves the stamping accuracy. (3) In this utility model, the lower mold base is set in the guide groove through the sliding fit between the guide rail and the guide groove. The locking block in the locking assembly engages with the slot of the operating table under the elastic force of the first spring, thereby fixing the lower mold base. When it is necessary to replace the lower mold base, simply overcome the elastic force of the first spring to pull the slider, so that the locking block disengages from the slot, and the lower mold base can be slid out along the guide groove. The operation is simple and quick, reducing the time for mold replacement and improving production efficiency. (4) In this utility model, the discharge hopper at the bottom of the operating table is connected to the discharge hole on the lower die base. The waste generated by stamping can enter the discharge hopper through the discharge hole, which is convenient for centralized collection and treatment, avoids the accumulation of waste on the operating table, improves the production environment, and also reduces the interference of waste on subsequent processing. (5) The structure of this utility model is reasonable, the connection and cooperation logic between the components is clear, the function is perfect, it overcomes the shortcomings of the prior art, improves the overall level of stamping processing, and is suitable for widespread application.

[0020] Example 1: The main structure of this embodiment is as follows: Figures 1-5 As shown, it includes: A base 1, on which an operating table 2 is provided, and a guide groove 201 is provided on the operating table 2; The lower mold base 4 is slidably disposed in the guide groove 201. The lower mold base 4 is provided with a locking component that engages with the operating table 2. The guide groove 201 is provided with a first conveyor belt 9 and a second conveyor belt 10 at intervals along the metal sheet conveying direction and located at the input end of the lower mold base 4. The bracket 14 is fixed on the operating table 2. The bracket 14 is movably and vertically provided with an upper mold base 15 and a pressure plate 17. The upper mold base 15 is located directly above the lower mold base 4. The bottom of the pressure plate 17 is provided with two first rotating shafts 19 that are rotatably connected to it. The pressure plate 17 is provided with a tensioning component for driving the first rotating shafts 19 to rotate elastically to keep the movable frame 20 in a tensioned state. The movable frame 20 includes two movable frames, each of which is fixedly connected to a first rotating shaft 19 on a corresponding side. Each of the two movable frames 20 is provided with a pressure roller 23 that can only rotate in one direction along the metal sheet conveying direction at the end away from the first rotating shaft 19. A first drive assembly is mounted on the bracket 14 and drives the upper mold base 15 to rise or fall. And a second drive assembly, which is mounted on the bracket 14 and drives the pressure plate 17 to rise or fall.

[0021] The specific implementation process is as follows: the metal sheet to be processed is pulled from the feeding roller 28 onto the first conveyor belt 9 and the second conveyor belt 10, so that its front end is aligned with the stamping area of ​​the lower die base 4; the second drive assembly is activated, driving the pressure plate 17 to descend, and the pressure roller 23 contacts the upper surface of the metal sheet. The tensioning assembly maintains pressure on the movable frame 20 through the first rotating shaft 19, ensuring that the pressure roller 23 is in close contact with the metal sheet; the first conveyor belt 9 and the second conveyor belt 10 are activated, and in conjunction with the unidirectional rotation of the pressure roller 23, the metal sheet is conveyed to the stamping area; when the metal sheet reaches the set stamping position, the first drive assembly drives the upper die base 15 to descend, and in conjunction with the lower die base 4, completes one stamping; after the stamping is completed, the upper die base 15 rises, the pressure plate 17 rises synchronously, and the pressure roller 23 rotates freely with the direction of movement of the metal sheet, ready for the next feeding. The above steps are repeated to achieve continuous stamping.

[0022] Example 2: This embodiment, based on the above embodiment, further adds a discharge hopper 3. As shown in the figure, the bottom of the operating table 2 is provided with a discharge hopper 3 that communicates with the guide groove 201. The lower die base 4 is provided with a discharge hole 401 that is adapted to and communicates with the discharge hopper 3. Waste materials generated during stamping, such as scraps, fall directly into the discharge hopper 3 through the discharge hole 401, avoiding the accumulation of waste materials on the surface of the lower die base 4 and affecting subsequent processing.

[0023] The specific implementation process is as follows: the waste material generated during stamping remains on the surface of the lower die base 4; as the metal sheet is continuously conveyed, a new area to be stamped covers the lower die base 4, and the waste material, pushed by subsequent metal sheets or by its own gravity, falls through the discharge hole 401 into the discharge hopper 3 below; the waste material in the discharge hopper 3 is cleaned regularly to ensure that the discharge channel is unobstructed. The other parts of this embodiment are the same as those in the above embodiment and will not be described again.

[0024] Example 3: This embodiment further defines the structure of the lower mold base 4 based on the above embodiments, such as... Figure 3 As shown, two sets of guide rails 403 are symmetrically arranged on both sides of the lower die base 4, and grooves that slide and adapt to the guide rails 403 are symmetrically opened on both sides of the inner wall of the guide groove 201. The guide rails 403 restrict the movement direction of the lower die base 4 in the guide groove 201, ensuring that the stamping position of the lower die base 4 and the upper die base 15 are aligned, and at the same time, it facilitates the quick assembly and disassembly of the lower die base 4.

[0025] The specific implementation process is as follows: When installing the lower mold base 4, align the guide rails 403 on both sides of it with the grooves on the inner wall of the guide groove 201, and push it into the guide groove 201 along the direction of the groove; during the pushing process, the guide rails 403 slide with the groove to ensure that the lower mold base 4 moves horizontally and does not deviate, until the locking component is locked and fixed to the operating table 2; when replacing the lower mold base 4, loosen the locking component, pull out the old lower mold base 4 along the direction of the cooperation between the guide rails 403 and the groove, and then install the new lower mold base 4 according to the above steps. The other parts of this embodiment are the same as those in the above embodiment, and will not be described again.

[0026] Example 4: This embodiment further defines the structure of the locking assembly based on the above embodiments, such as... Figures 1-3 As shown, the locking assembly includes a slider 6 and a locking block 7. A groove 402 is provided on the lower mold base 4, and a slot communicating with the guide groove 201 is provided on the operating table 2. The slider 6 is located within the groove 402 and slidably connected to the inner wall of the groove 402. Two sliding rods 5 are provided within the groove 402, passing through the slider 6 along the length of the groove 402 and slidably connected to it. One end of the locking block 7 is fixedly connected to the slider 6, and the other end is slidably inserted into the slot and abuts against the inner wall of the slot. A first spring 8 is sleeved on the sliding rod 5, with both ends of the first spring 8 abutting against the side of the slider 6 away from the locking block 7 and the inner wall of the groove 402, respectively. The sliding rod 5 provides guidance for the slider 6. The elastic force of the first spring 8 pushes the slider 6, causing the locking block 7 to insert into the slot of the operating table 2, thus locking. External force pulling the slider 6 compresses the first spring 8, causing the locking block 7 to disengage from the slot and release the lock.

[0027] The specific implementation process is as follows: When installing the lower mold base 4, the slider 6 moves along the slide rod 5 towards the slot under the elastic force of the first spring 8, causing the locking block 7 to insert into the slot of the operating table 2, thus completing the locking and fixing of the lower mold base 4; when the lower mold base 4 needs to be disassembled, the slider 6 is pulled away from the slot, the slider 6 compresses the first spring 8 and causes the locking block 7 to disengage from the slot, at which point the lower mold base 4 can be pulled out along the guide rail 403; after releasing the slider 6, the first spring 8 resets, pushing the slider 6 and the locking block 7 back to the initial position, waiting for the next locking. The other parts of this embodiment are the same as those in the above embodiment, and will not be described again.

[0028] Example 5: This embodiment, based on the above embodiment, further adds a support component, such as... Figure 2 As shown, the guide groove 201 is provided with two sets of support components. Each set of support components includes a support plate and two drive rollers. The two drive rollers are rotatably mounted on the support plate. The first conveyor belt 9 and the second conveyor belt 10 are respectively wound around and driven to the two drive rollers of the corresponding side support components, and the two support plates are in sliding contact with the bottom surfaces of the support ends of the first conveyor belt 9 and the second conveyor belt 10. The drive rollers drive the first conveyor belt 9 and the second conveyor belt 10 to move synchronously by rotating. The support plates are in contact with the bottom surface of the conveyor belts to prevent the conveyor belts from sagging due to the weight of the metal sheets and to ensure that the conveying plane is flat.

[0029] The specific implementation process is as follows: The drive roller device is activated, and the drive rollers of the two sets of support components rotate synchronously, driving the first conveyor belt 9 and the second conveyor belt 10 to move along the metal sheet conveying direction. The metal sheet is placed on the first conveyor belt 9 and the second conveyor belt 10, and the support plate supports the conveyor belt from below to prevent the conveyor belt from denting due to the weight of the metal sheet. During the operation of the conveyor belt, the support plate slides in contact with the bottom surface of the conveyor belt to reduce conveyor belt vibration and ensure that the metal sheet is smoothly conveyed to the stamping area. Other parts of this embodiment are the same as those in the above embodiment and will not be repeated.

[0030] Example 6: This embodiment, based on the above embodiment, further defines the positional relationship between the first conveyor belt 9 and the second conveyor belt 10, such as... Figure 2As shown, a positioning channel is formed between the first conveyor belt 9 and the second conveyor belt 10. Two clamping plates 11, symmetrically connected to the operating platform 2, are arranged within the positioning channel. The two clamping plates 11 are located on opposite sides of the metal sheet conveying path. Several rotatable guide wheels 12 are spaced apart on the side of each clamping plate 11 that is close to each other. The operating platform 2 is equipped with a bidirectional module 13 for driving the clamping plates 11 to move synchronously closer or further away along a direction perpendicular to the metal sheet conveying direction. The bidirectional module 13 drives the clamping plates 11 to move along a direction perpendicular to the conveying direction, adjusting the spacing to accommodate metal sheets of different widths. The guide wheels 12 roll in contact with the sides of the metal sheets, reducing friction while limiting metal sheet offset and ensuring straight conveying. The specific implementation process is as follows: Based on the width of the metal sheet, the bidirectional module 13 is activated, driving the two side clamping plates 11 to move synchronously closer or further away, ensuring that the guide wheels 12 on both sides are in contact with the sides of the metal sheet while maintaining a small gap to avoid excessive friction; the metal sheet enters the positioning channel under the drive of the first conveyor belt 9 and the second conveyor belt 10, and the guide wheels 12 on both sides rotate as the metal sheet moves, limiting the left and right deviation of the metal sheet; after passing through the positioning channel, the metal sheet maintains a straight line and enters the stamping area, ensuring that the upper die holder 15 and the lower die holder 4 are precisely aligned in the stamping position. Other parts of this embodiment are the same as those in the above embodiment and will not be repeated.

[0031] Example 7: This embodiment, based on the above embodiment, further adds a second rotating shaft 22, such as... Figure 5 As shown, the movable frame 20 has a second rotating shaft 22 fixedly installed at one end away from the first rotating shaft 19. The pressure roller 23 is rotatably sleeved on the second rotating shaft 22 and coaxially arranged with the second rotating shaft 22. A circular groove coaxial with the pressure roller 23 is opened in the roller 23, and a side groove communicating with the circular groove is opened on the side wall of the pressure roller 23. A ratchet 24 coaxially and fixedly connected to the second rotating shaft 22 is provided in the circular groove. The ratchet 24 can rotate coaxially with the pressure roller 23. A second spring 25 is provided in the side groove. One end of the second spring 25 is connected to the inner wall of the side groove, and the other end is connected to a ratchet 26. The ratchet 26 engages with the ratchet 24 in one direction under the elastic force of the second spring 25. The second rotating shaft 22 is fixed to the movable frame 20, and the ratchet 24 is coaxially connected to the second rotating shaft 22. The pressure roller 23 is sleeved on the second rotating shaft 22, and the ratchet 26 in its side groove engages with the ratchet 24 under the action of the second spring 25. The ratchet is only allowed to rotate in the direction of metal sheet conveying. When rotating in the opposite direction, the ratchet is stuck in the ratchet to prevent the metal sheet from rebounding.

[0032] The specific implementation process is as follows: When the pressure plate 17 descends, the pressure roller 23 contacts the metal sheet and moves towards the stamping area. At this time, the pressure roller 23 rotates in the conveying direction, and the ratchet 26 slides on the tooth surface of the ratchet 24. The second spring 25 is slightly compressed and then reset, without affecting the rotation. After the metal sheet is conveyed to the position, the pressure plate 17 rises, and the pressure roller 23 separates from the metal sheet. If the metal sheet attempts to move in the opposite direction due to stress rebound, the ratchet 26 is engaged in the tooth groove of the ratchet 24 under the action of the second spring 25, restricting the reverse rotation of the pressure roller 23, thereby preventing the metal sheet from rebounding. When the pressure plate 17 descends again, the pressure roller 23 re-adheres to the metal sheet, and the above-mentioned directional rotation process is repeated to ensure accurate feeding length each time. The other parts of this embodiment are the same as those in the above embodiment and will not be described again.

[0033] Example 8: This embodiment, based on the above embodiment, further adds a waste collection box. A detachable waste collection box is located at the bottom of the operating platform 2, corresponding to the area below the first conveyor belt 9 and the second conveyor belt 10. The top opening of the waste collection box communicates with the bottom of the guide groove 201, and the side wall of the waste collection box is provided with a handle for pulling it out. The top opening of the collection box communicates with the guide groove 201, ensuring that waste falls directly into the box, and the pull handle facilitates quick retrieval and cleaning.

[0034] The specific implementation process is as follows: when the metal sheet is conveyed on the first conveyor belt 9 and the second conveyor belt 10, the debris attached to the surface or the small waste materials scattered at the edges fall off due to gravity and fall into the waste collection box below through the bottom opening of the guide groove 201; when the waste material in the collection box accumulates to a certain amount, it is pulled out from the bottom of the operating table 2 through the side wall handle, the waste material is emptied and then put back in its original position to ensure that the conveying area is clean. The other parts of this embodiment are the same as those in the above embodiment and will not be described again.

[0035] Example 9: This embodiment, based on the above embodiment, further adds a buffer component. A buffer component is provided between the upper mold base 15 and the output end of the first drive component. The buffer component includes a buffer spring and a guide post. One end of the guide post is fixedly connected to the upper mold base 15, and the other end slides through the output end of the first drive component. The buffer spring is sleeved on the guide post, and both ends of the buffer spring abut against the upper mold base 15 and the output end of the first drive component, respectively. The guide post ensures that the upper mold base 15 moves vertically. The buffer spring is compressed during the stamping process, absorbing part of the impact force, reducing the rigid collision between the upper mold base 15 and the lower mold base 4, and protecting the mold and the drive component.

[0036] The specific implementation process is as follows: When the first drive assembly drives the upper die holder 15 to descend for stamping, the buffer spring is compressed the instant the upper die holder 15 contacts the metal sheet, converting part of the impact force into the spring's elastic potential energy and reducing the impact stress at the contact of the die; after stamping is completed, the first drive assembly drives the upper die holder 15 to rise, the buffer spring resets, and the guide post ensures that the upper die holder 15 rises vertically back to its initial position, avoiding deviation that could affect the next stamping. Other parts of this embodiment are the same as those in the above embodiment and will not be repeated here.

[0038] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
