Description

Technical Field

[0001] This invention relates to the field of continuous stamping die technology, and more particularly to a continuous stamping die for connecting spring pieces. Background Technology

[0002] The manufacturing process of connecting springs begins with stamping the connecting springs onto a flat surface using a stamping die, followed by manual folding and shaping by workers. Due to the influence of human factors such as worker skill levels, the shaping and elasticity of the produced connecting springs are uncontrollable, resulting in unstable quality, affecting the lifespan of the connecting springs, and consequently, the lifespan of electronic products.

[0003] Existing stamping dies include an upper die, a lower die, an upper die fixing plate, and a lower die fixing plate. The upper die is fixed on the upper die fixing plate, and the lower die is fixed on the lower die fixing plate. A spring-compression type pressure plate can also be provided on the upper die fixing plate, and a spring-spring-opening type stripper plate can be provided on the lower die.

[0004] A continuous stamping die for producing connecting spring pieces, with announcement number CN102935465A, includes an upper die, a lower die, an upper die fixing plate, and a lower die fixing plate. The upper die is fixed on the upper die fixing plate, and the lower die is fixed on the lower die fixing plate. The upper die is equipped with punches for all processes of producing the connecting spring pieces, and all punches are arranged equidistantly in a straight line according to the processing steps. The lower die is equipped with dies for all processes of producing the connecting spring pieces, and all dies are arranged equidistantly in a straight line according to the processing steps. The punches and dies correspond one-to-one. This invention's die includes punches and dies for all processes of producing connecting spring pieces. A set of processes can be completed in one stamping operation, resulting in a formed part at the last station. Then, the strip is fed in one unit distance, and the next stamping operation can be performed. The processing speed is fast, and the product dimensional accuracy is high.

[0005] The above technical solution enables materials to move sequentially. Conventional technical components cannot guarantee the stable movement of the plate to be stamped and are not conducive to achieving smooth flattening of the plate. Therefore, improvements are needed. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a continuous stamping die for connecting spring sheets.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A continuous stamping die for connecting spring pieces includes a base assembly, the upper end of which is provided with a stamping mechanism, and the stamping mechanism is provided with a pressure plate and two positioning rods; A power mechanism is installed at one end of the base assembly, and a lower shaft is provided on the power mechanism. The stamping mechanism corresponds to the lower shaft. One end of the pressure plate is equipped with an abutting linkage mechanism.

Two first reset components are installed on the positioning rod. The upper ends of the two first reset components are fixed with a bearing plate. A top plate is provided through the bearing plate. The upper end of the top plate extends to the upper end of the bearing plate. A second reset component is installed at the lower end of the top plate. The second reset component is connected to the positioning rod.

[0008] Compared with the prior art, this application can realize the operation of the continuous stamping die assembly by controlling the lifting and lowering of the pressure plate, so as to perform continuous stamping operation on the plate to be stamped. At the same time, it can fully adapt to the specifications of the plate to be stamped, so as to accurately control its movement distance, and facilitate the stamping position to pass between different dies in the continuous stamping die assembly in sequence, and cooperate with the stamping die to complete the stamping.

[0009] Preferably, the power mechanism includes a drive assembly mounted on the base assembly, the drive assembly being connected to one end of the lower shaft, the lower shaft being rotatably sleeved on one side of the base assembly, and one of the abutting gears being mounted on the lower shaft.

[0010] Furthermore, the drive assembly consists of a motor, two drive wheels, and a drive belt fitted on the two drive wheels. The motor can drive one of the drive wheels to rotate, so that the drive belt can rotate the drive wheel connected to the lower shaft. Moreover, the drive wheels and drive belt adopt a toothed structure to ensure stable transmission. Meanwhile, the necessary supporting components for the automation components, such as power supply, control, and installation equipment, are all conventional technologies in the field and do not need to be disclosed again.

[0011] Preferably, the stamping mechanism includes two hydraulic cylinder assemblies disposed on the upper end of the base assembly, the piston rod ends of the two hydraulic cylinder assemblies are jointly fixed with a pressure plate, and the upper end of the base assembly and the lower end of the pressure plate are jointly fixed with a continuous stamping die assembly. The upper end of the lower shaft is flush with the lower die component in the continuous stamping die assembly.

[0012] Furthermore, the hydraulic cylinder assembly is a hydraulic cylinder component that can drive the pressure plate to rise and fall. At the same time, the continuous stamping die assembly includes a lower stamping die assembly and an upper stamping die assembly. The lower die assembly and the base assembly are detachably connected, and the upper die assembly and the pressure plate are fixedly connected. The upper and lower die assemblies are continuous stamping die components that can stamp sheet metal into the required parts.

[0013] Preferably, the abutting linkage mechanism includes two through holes opened at one end of the pressure plate member, a reversing mechanism is installed in the through holes, a fixing plate is installed on both of the two reversing mechanisms, and a connecting frame is fixed on both sides of one end of the fixing plate, and the two ends of the upper shaft member are respectively rotatably sleeved on the two connecting frames. The connecting frame is provided with an adaptation mechanism, which is provided with a rotating shaft and a collar. The collar is fixedly fitted onto one end of the upper shaft, and another abutting gear is fixed onto the rotating shaft.

[0014] Furthermore, clever components are installed within the through-hole to allow the hydraulic cylinder assembly to control the descent of the upper shaft as it rises, so that the upper and lower shafts can press against the upper and lower ends of the plate. Power transmission is also controlled to ensure that the upper and lower shafts rotate at the same speed, which helps to move the plate smoothly.

[0015] Preferably, the reversing mechanism includes two second toothed conditions fixed on both sides of the upper end of the base assembly. The two second toothed conditions are slidably installed in two through holes. A second gear is rotatably sleeved at one end of the through hole near the upper shaft, and the second gear meshes with the second toothed conditions. One end of the second gear component is fixed to the first gear component, and the first gear component is slidably installed on one side of the second gear component. An elastic mechanism is provided on one side of the first gear component, and the elastic mechanism is connected to the side wall inside the through-hole. The fixing plate and the two first teeth are fixedly connected.

[0016] Furthermore, in actual operation, the hydraulic cylinder assembly can drive the pressure plate to rise, that is, the second gear and the first gear will rise with the pressure plate. The second gear and the second gear mesh with each other, so that the second gear drives the first gear to rotate. Meanwhile, the specifications of the first gear component are larger than those of the second gear component, and during operation, the specifications of the first and second gear conditions can be controlled so that the first gear condition can move downward when the hydraulic cylinder assembly rises.

[0017] Preferably, the elastic mechanism includes a slide rod fixed to one side of the first tooth condition, a partition is slidably mounted on the slide rod, one end of the partition is fixed to the side wall inside the through opening, and a return spring is sleeved on the slide rod, with both ends of the return spring fixed to the upper end of the slide rod and the upper end of the partition, respectively.

[0018] Furthermore, when the first tooth condition moves downward under the action of the first gear component, the return spring component is compressed, which facilitates the rapid rise of the first tooth condition without the action of external force.

[0019] Preferably, the adaptation mechanism includes a lifting plate slidably mounted on a connecting frame, a lifting frame fixed at the lower end of the lifting plate, a tensioning mechanism provided between the lifting frame and the connecting frame, and the rotating shaft rotatably sleeved on one side of the lifting frame; A lifting frame is slidably installed on the upper end of the lifting plate. An elastic mechanism is provided between the lifting frame and the lifting plate. A rotating shaft is rotatably sleeved on the upper end of the lifting frame. A linkage belt assembly is installed on the collar, the rotating shaft, and the rotating shaft.

[0020] Furthermore, the connecting frame and the fixed plate are fixedly connected. Through the cooperation of the second resistance spring and the first resistance spring, the distance between the lifting frame and the lifting frame can reach the maximum possible distance, so that the linkage belt assembly can be fully tensioned. In actual operation, the linkage belt assembly can be a transmission belt assembly or a chain assembly. The linkage belt assembly consists of three drive wheels and a belt sleeved on the drive wheels. At the same time, toothed mechanisms are provided on both the drive wheels and the belt so that they can mesh with each other. The linkage belt assembly consists of three sprockets and a chain fitted on the sprockets, which ensures that the chain is fully tensioned; In actual operation, the fixed plate moves downward under the action of the first tooth condition, which makes the two abutting gear parts abut against each other. The rotation of the abutting gear part at the lower end can make the abutting gear part at the upper end rotate. At the same time, by designing the specifications of the parts, it can be ensured that the upper shaft part and the lower shaft part rotate at the same speed but in opposite directions, so as to give the upper and lower ends of the plate to be stamped a force that moves in the same direction.

[0021] Preferably, the tensioning mechanism includes a vertical shaft fixed on the lifting frame, the upper end of the vertical shaft being slidably mounted on the connecting frame, and a first resistance spring being sleeved on the connecting frame, with both ends of the first resistance spring being fixed to opposite sides of the lifting frame and the connecting frame, respectively.

[0022] Furthermore, the first resistance spring can push the lifting frame to move downward relative to the connecting frame, so that the lifting frame can drive the rotating shaft to move upward; That is, through the action of the first resistance spring and the second resistance spring, the distance between the rotating shaft can reach the maximum distance that can be achieved.

[0023] Preferably, the elastic mechanism includes a limiting plate fixed to the upper end of the lifting plate, a vertical shaft component slidably installed inside the limiting plate, the limiting plate being slidably installed inside the lifting frame, and a second resistance spring component sleeved on the vertical shaft component, the two ends of the second resistance spring component being fixed to the top of the lifting frame and the upper end of the limiting plate, respectively.

[0024] Furthermore, the lifting plate has a square tube structure, and the limiting plate is fixed to the upper end of the lifting plate. The lifting frame adopts an inverted U-shaped structure or a square frame structure, which allows the limiting plate to be installed through the lifting frame to facilitate the installation of the vertical shaft component. The upper end of the vertical shaft component is fixed to the top of the lifting frame, and the vertical shaft component is slidably installed on the limiting plate. According to the specifications and weight of the component installation, a suitable second resistance spring component is selected, and its elastic coefficient is controlled to ensure that the second resistance spring component can push the lifting frame to move relatively upward so that the rotating shaft component can reach its position.

[0025] Preferably, the specifications of the first gear component are larger than those of the second gear component.

[0026] Furthermore, the first gear and the second gear are coaxially arranged, and the second gear can drive the first gear to rotate. The linear velocity of the first gear is greater than that of the second gear. This makes the linear velocity of the first gear greater than that of the pressure plate. By controlling the difference in linear velocities, it is easy to control the descent speed of the upper shaft, which helps to clamp the stamped plate with the upper and lower shafts and apply force to its movement. In actual operation, the ratio of the circumference of the first gear and the second gear, or the ratio of the number of teeth, is calculated according to the actual situation so that the descent speed of the first gear can be faster than the rise speed of the pressure plate, and the lifting range of the pressure plate can be controlled. The calculation and operation are existing technologies and do not need to be disclosed again.

[0027] The beneficial effects of this invention are: Through the clever cooperation between the components, the stamping plate can be quickly contacted when the mold is separated, so that the upper and lower ends of the plate can be applied with a force moving in the same direction. This allows the stamping plate to move smoothly along the direction of the continuous stamping mold assembly, so that the stamping plate can move smoothly to the next step position after the previous stamping step is completed, realizing continuous stamping operation, so as to complete the stamping preparation of the spring sheet. The power mechanism allows for easy operation under the control of staff, providing power for the rotation of the upper and lower shafts. In actual operation, the operation of the power mechanism and the lifting and lowering of the hydraulic cylinder assembly are controlled to ensure full coordination. Sufficient time is allowed after the hydraulic cylinder assembly drives the pressure plate and the upper die assembly in the continuous stamping die assembly to rise, so that the power mechanism can start and move the plate to be stamped. After the movement is completed, the power mechanism stops operating, allowing the hydraulic cylinder assembly to push the pressure plate down to complete the stamping operation. The upper and lower shafts rotate in opposite directions through the engagement of two opposing gear components, while ensuring that the upper and lower shafts rotate at the same speed, so as to smoothly drive the plate to be stamped to move. The movement range of the top plate and the bearing plate is controlled. When the upper and lower stamping die components in the continuous stamping die assembly are separated, the movement speed is controlled to avoid vibration and ensure the stability of the sheet metal. After the bearing plate rises, there is a certain distance between the sheet metal and the upper end of the lower die in the continuous stamping die assembly, which facilitates the movement of the sheet metal under the action of the lower and upper shafts.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] Reference Figures 1-7 A continuous stamping die for connecting spring pieces includes a base assembly 1, a stamping mechanism at the upper end of the base assembly 1, and a pressure plate 3 and two positioning rods 19 on the stamping mechanism; A power mechanism is installed at one end of the base assembly 1, and a lower shaft 15 is provided on the power mechanism. The stamping mechanism corresponds to the lower shaft 15. The base assembly 1 is the equipment base, and the power supply, control and other components required for the operation of the automated components in this application can be installed inside it. At the same time, the automated components in this application are all existing equipment, and their operating principles and control methods are common knowledge and do not need to be disclosed again. Through the ingenious cooperation between the components, this application can quickly abut the plate to be stamped when the mold separates, so that the upper and lower ends of the plate can be applied with a force moving in the same direction, so that the plate to be stamped can move smoothly along the direction of the continuous stamping mold assembly 2, which facilitates the plate to be stamped. After the previous stamping step is completed, the device smoothly moves to the next step position to achieve continuous stamping operation, so as to complete the stamping preparation of the spring sheet. The power mechanism can be easily operated by the operator to provide power for the rotation of the upper shaft 9 and the lower shaft 15. At the same time, in actual operation, the operation of the power mechanism and the lifting and lowering of the hydraulic cylinder assembly 4 are controlled to ensure full coordination. That is, after the hydraulic cylinder assembly 4 drives the pressure plate 3 and the upper mold assembly in the continuous stamping die assembly 2 to rise, sufficient time is allowed to allow the power mechanism to start and drive the plate to be stamped to move. At the same time, when the movement is completed, the power mechanism stops operating, so that the hydraulic cylinder assembly 4 can push the pressure plate 3 down to complete the stamping operation.

[0031] In this embodiment, a contact linkage mechanism is installed at one end of the pressure plate 3. Both the contact linkage mechanism and the power mechanism are provided with contact gears 7. The contact linkage mechanism is provided with an upper shaft 9, which is located at the upper end of the lower shaft 15. The contact linkage mechanism can realize the transmission of power. That is, when the lower shaft 15 rotates, the upper shaft 9 and the lower shaft 15 can be rotated in opposite directions through the cooperation between the two contact gears 7. At the same time, the upper shaft 9 and the lower shaft 15 rotate at the same speed, so as to smoothly drive the plate to be pressed to move.

Second reset components 20 are installed on the lower ends of the top plate 16, and the second reset components 20 are connected to the positioning rod 19. When the hydraulic cylinder assembly 4 pushes the pressure plate 3 and the upper stamping die assembly thereon to descend, it first contacts the top plate 16 and pushes the top plate 16 down to contact the top of the sheet metal. Finally, it pushes the sheet metal and the bearing plate 17 down, causing the lower end of the sheet metal to contact the lower die inside the continuous stamping die assembly 2. The upper end abuts; at the same time, the first reset component 18 and the second reset component 20 are both composed of rods and springs sleeved on them. The rods are slidably mounted on the positioning rod 19, and the springs are fixed to the lower end of the corresponding rods and the lower end of the positioning rod 19. At the same time, corresponding limiting components are set to control the movement range of the top plate 16 and the bearing plate 17. When the upper and lower stamping die components in the continuous stamping die assembly 2 are separated, the movement speed is controlled to avoid vibration and ensure the stability of the sheet metal. After the bearing plate 17 rises, it can make the sheet metal and the upper end of the lower die in the continuous stamping die assembly 2 have a certain distance, which facilitates the movement of the sheet metal under the action of the lower shaft 15 and the upper shaft 9.

The drive assembly 14 consists of a motor, two drive wheels, and a power belt sleeved on the two drive wheels. The motor can drive one of the drive wheels to rotate, so that the drive belt can rotate the drive wheel connected to the lower shaft 15. Moreover, the drive wheel and the power belt adopt a toothed structure for stable transmission. Meanwhile, the necessary supporting components for the automation components, such as power supply, control, and installation equipment, are all conventional technologies in the field and do not need to be disclosed again.

[0034] In this embodiment, the stamping mechanism includes two hydraulic cylinder assemblies 4 disposed on the upper end of the base assembly 1. The piston rod ends of the two hydraulic cylinder assemblies 4 are jointly fixed with a pressure plate 3. The upper end of the base assembly 1 and the lower end of the pressure plate 3 are jointly fixed with a continuous stamping die assembly 2. The upper end of the lower shaft 15 and the lower die component in the continuous stamping die assembly 2 are flush. The hydraulic cylinder assembly 4 is a hydraulic cylinder component that can drive the pressure plate 3 to rise and fall. At the same time, the continuous stamping die assembly 2 includes a lower stamping die assembly and an upper die assembly. The lower die assembly and the base assembly 1 are detachably connected, and the upper die assembly and the pressure plate 3 are fixedly connected. The upper and lower die assemblies are continuous stamping die components that can stamp sheet metal into the required components.

The collar 10 is fixedly fitted onto one end of the upper shaft 9, and another abutting gear 7 is fixed on the rotating shaft 6. Another abutting gear 7 is disposed above one of the abutting gear 7; a clever component is installed in the through opening 5 so that when the hydraulic cylinder assembly 4 rises, it can control the upper shaft 9 to descend so that the upper shaft 9 and the lower shaft 15 can press the upper and lower ends of the plate, and can control the power transmission so that the upper shaft 9 and the lower shaft 15 rotate at the same speed, which helps to make the plate move smoothly.

[0036] In this embodiment, the reversing mechanism includes two second tooth conditions 26 fixed on both sides of the upper end of the base assembly 1. The two second tooth conditions 26 are slidably installed in the two through holes 5 respectively. A second gear 25 is rotatably sleeved at one end of the through hole 5 near the upper shaft 9.

An elastic mechanism is provided on one side of the first gear condition 21, and the elastic mechanism is connected to the side wall inside the through-hole 5. The fixed plate 27 is fixedly connected to the two first gear conditions 21. The hydraulic cylinder assembly 4 can drive the pressure plate component 3 to rise, that is, the second gear component 25 and the first gear component 28 will rise with the pressure plate component 3. The second gear component 25 and the second gear condition 26 mesh, so that the second gear component 25 drives the first gear component 28 to rotate. Meanwhile, the specifications of the first gear component 28 are larger than those of the second gear component 25, and during operation, the specifications of the first tooth condition 21 and the second tooth condition 26 can be controlled so that the first tooth condition 21 can move downward when the hydraulic cylinder assembly 4 rises.

[0037] In this embodiment, the elastic mechanism includes a slide bar 22 fixed to one side of the first gear condition 21. A partition 24 is slidably mounted on the slide bar 22.

A linkage belt assembly 8 is mounted on the collar 10, the rotating shaft 6, and the rotating shaft 11. The connecting frame 12 and the fixing plate 27 are fixedly connected. Through the cooperation of the second resistance spring 33 and the first resistance spring 30, the distance between the lifting frame 29 and the lifting frame 13 can reach the maximum possible distance so that the linkage belt assembly 8 can be fully tensioned. In actual operation, the linkage belt assembly 8 can be a transmission belt assembly or a chain assembly. The linkage belt assembly 8 consists of three drive wheels and a belt sleeved on the drive wheels. At the same time, toothed mechanisms are provided on both the drive wheels and the belt so that they can mesh with each other. The linkage belt assembly 8 consists of three sprockets and a chain sleeved on the sprockets, which can ensure that the chain is fully tensioned; In actual operation, the fixed plate 27 moves downward under the action of the first tooth condition 21, which makes the two abutting gear parts 7 abut against each other. The rotation of the abutting gear part 7 at the lower end can make the abutting gear part 7 at the upper end rotate. At the same time, by designing the specifications of the components, it can be ensured that the upper shaft part 9 and the lower shaft part 15 rotate at the same speed but in opposite directions, so as to give the upper and lower ends of the plate to be stamped a force that moves in the same direction.

[0039] In this embodiment, the tensioning mechanism includes a vertical shaft 32 fixed on the lifting frame 13. The upper end of the vertical shaft 32 is slidably mounted on the connecting frame 12. A first resistance spring 30 is sleeved on the connecting frame 12. The two ends of the first resistance spring 30 are respectively fixed on opposite sides of the lifting frame 13 and the connecting frame 12. The first resistance spring 30 can push the lifting frame 13 to move downward relative to the connecting frame 12, so that the lifting frame 13 can drive the rotating shaft 6 to move upward.

The two ends of the second resistance spring 33 are respectively fixed to the top of the lifting frame 29 and the upper end of the limiting plate 35. The lifting plate 31 is a square tube structure. The limiting plate 35 is fixed to the upper end of the lifting plate 31. The lifting frame 29 adopts an inverted U-shaped structure or a square frame structure, which allows the limiting plate 35 to be installed through the lifting frame 29 for the installation of the vertical shaft 34. The upper end of the vertical shaft 34 is fixed to the top of the lifting frame 29. The vertical shaft 34 is slidably installed on the limiting plate 35. A suitable second resistance spring 33 is selected according to the specifications and weight of the component installation, and its elastic coefficient is controlled to ensure that the second resistance spring 33 can push the lifting frame 29 to move upward relative to each other, so as to drive the rotating shaft 11 to reach its reachable position.

[0041] In this embodiment, the specifications of the first gear component 28 are larger than those of the second gear component 25; the first gear component 28 and the second gear component 25 are coaxially arranged, and the second gear component 25 can drive the first gear component 28 to rotate. The linear velocity of the first gear component 28 is greater than the linear velocity of the second gear component 25. This will make the linear velocity of the first gear component 21 greater than the linear velocity of the pressure plate component 3. By controlling the difference in linear velocities, it is easy to control the descent speed of the upper shaft component 9, which helps the upper shaft component 9 and the lower shaft component 15 to clamp the stamping plate and apply force to its movement. In actual operation, the ratio of the circumference of the first gear component 28 or the ratio of the number of teeth of the second gear component 25 is calculated according to the actual situation so that the descent speed of the first gear component 21 can be faster than the rise speed of the pressure plate component 3, and the lifting range of the pressure plate component 3 can be controlled. The calculation and operation are existing technologies and do not need to be disclosed again.

[0042] In this embodiment, the power mechanism can be easily operated by the operator to provide power for the rotation of the upper shaft 9 and the lower shaft 15. When the hydraulic cylinder assembly 4 drives the pressure plate 3 to rise, the upper shaft 9 will move towards the lower shaft 15. The transmission is achieved through the engagement of two abutting gears 7. The teeth on the two abutting gears 7 have an arc-shaped structure, which facilitates relative contact and engagement. The upper shaft 9 and the lower shaft 15 can push the plate to move within the continuous stamping die assembly 2. The movement time is within the time range of the hydraulic cylinder assembly 4 driving the pressure plate 3 to rise and fall. Within this range, after the plate is lifted and clamped by the upper shaft 9 and the lower shaft 15, the plate is pushed forward, so that the plate that has completed the previous stamping process moves to the next process to complete the continuous stamping operation.
