Abstract
Description
Technical Field
[0001] The present application relates to the technical field of stamping dies, and in particular to a stamping continuous die for a leaf spring bracket of an automobile seat. Background Art
[0002] As a crucial component of car seats, the quality and production efficiency of automotive seat leaf spring brackets are crucial to the automotive manufacturing industry. Currently, the production of automotive seat leaf spring brackets generally utilizes progressive die technology, which utilizes a series of precisely designed dies and automated equipment to achieve efficient, continuous stamping of metal blanks.
[0003] During the stamping process, a metal blank is fed into the die system via a continuous conveyor. The die system typically consists of a fixed die and a movable die. The fixed die is stationary and serves as a reference surface for the stamping process, ensuring the dimensional and shape accuracy of the formed part. Driven by a pressing mechanism, the movable die periodically rises and falls, applying pressure to the blank to achieve the desired stamping result. After stamping is complete, the continuous conveyor restarts, moving the metal blank forward to the next station for the next round of stamping.
[0004] However, in actual production, if an operator's hand accidentally gets caught between the fixed and movable molds, the rapid movement of the movable mold can easily cause an arm crush. This type of accident not only causes serious bodily injury to the operator but also disrupts the normal operation of the production line, resulting in financial losses and project delays.
[0005] Therefore, the present application provides a continuous stamping die for a leaf spring bracket of an automobile seat to solve the above problems. Utility Model Content
[0006] The present application provides a stamping continuous die for a leaf spring bracket of an automobile seat, which aims to solve the problem of the existing stamping continuous die proposed in the background art, in which when the operator's hand is accidentally placed between the fixed die and the movable die during use, the operator's arm may be easily squeezed due to the rapid lifting and lowering movement of the movable die.
[0007] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a continuous die for stamping a leaf spring bracket for an automobile seat, comprising a fixed die, a movable die disposed on the fixed die, and a protective structure for pushing out an arm located between the fixed die and the movable die when the fixed die and the movable die are merged;
[0008] To facilitate the removal of hands between the movable and fixed molds during closing, ensuring production safety, the protective structure includes a push plate positioned between the two molds; a guide member symmetrically positioned on the fixed mold near one end of the movable mold and connected to both ends of the push plate to guide the movement of the push plate; and a hinged plate symmetrically hinged to the movable mold and hinged at both ends to drive the movement of the push plate. During the stamping process of the continuous mold, when the movable mold begins to descend, the hinged plate rotates accordingly. Because the hinged plate is hinged to both ends of the push plate, its rotation drives the push plate's movement. If an operator's arm accidentally gets caught between the fixed and movable molds, the push plate will promptly remove it, preventing the arm from being crushed. Once the movable mold completes stamping and rises, the hinged plate and push plate return to their original positions, ready for the next round of stamping. This innovative protective structure improves production safety in the continuous mold for stamping automotive seat leaf spring brackets while ensuring production efficiency and convenient equipment maintenance.
[0009] Preferably, to facilitate the movement of the push plate, the guide member includes a guide rail fixed to the fixed mold and a slider slidably mounted on the guide rail and hingedly connected to the hinge plate. The cooperation of the guide rail and the slider effectively guides and supports the push plate during movement, avoiding safety hazards caused by shaking or deviation.
[0010] Preferably, in order to facilitate the connection between the slider and the pushing plate, a bracket plate fixedly connected to the pushing plate is fixedly mounted on the slider by bolts. By introducing the bracket plate, the connection between the slider and the pushing plate is more secure, avoiding safety hazards caused by loose connection.
[0011] Preferably, to reduce wear on the hinged plate during use, bearings are provided at the hinged joints. The introduction of bearings significantly reduces friction and wear during the hinged joint, extending the service life of the hinged plate and reducing wear-related failure rates. The introduction of bearings improves the stability and reliability of the hinged plate during the hinged joint, ensuring the stability and safety of the protective structure over extended use.
[0012] Preferably, to maintain the hinged plate in a tilted position, the guide member is provided with a buffer mechanism comprising a fixed seat fixedly mounted on the guide rail, a movable seat slidably mounted on the guide rail between a corresponding slider and the fixed seat, and a buffer spring disposed between the fixed seat and the movable seat. The introduction of the buffer mechanism ensures that the hinged plate remains in an ideal tilted position during the stamping process, avoiding safety hazards caused by shaking or deviation. The elasticity and restoring force of the buffer spring compensate for deformation caused by the stamping load, thereby ensuring the stability and reliability of the protective structure during long-term use.
[0013] Preferably, to prevent deformation of the buffer spring due to uneven force, a guide rod is slidably inserted into the fixed seat, extending into the buffer spring and fixedly connected to the movable seat. A baffle is fixedly connected to the end of the guide rod distal from the movable seat. The combined structure of the guide rod and baffle ensures balanced force distribution across the buffer spring, preventing deformation and failure caused by uneven force. The introduction of the guide rod and baffle enhances the overall structural stability of the buffer mechanism and improves the protective structure's resistance to impact during the stamping process.
[0014] This application effectively avoids the risk of the operator's arm being squeezed during the stamping process by introducing a protective structure, significantly improving production safety. Due to the automated design of the protective structure, the arm can be pushed out without human intervention, thus ensuring the continuity and efficiency of the production line.

[0020] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0021] This embodiment provides a continuous die for stamping a leaf spring bracket of an automobile seat. Figure 1-3 As shown, the stamping continuous die includes a fixed die 1, a movable die 2 arranged on the fixed die 1, and a protective structure 3 for pushing out the arm located between the fixed die 1 and the movable die 2 when the fixed die 1 and the movable die 2 are merged;
[0022] To facilitate the ejection of hands between the movable and fixed molds 2 and 1 during closing, ensuring production safety, the protective structure 3 includes a push plate 31 corresponding to the movable and fixed molds 1 and 2, a guide member 32 symmetrically arranged on the fixed mold 1 near one end of the movable mold 2 and connected to both ends of the push plate 31 to guide the movement of the push plate 31, and a hinge plate 33 symmetrically hinged to the movable mold 2 and hinged to both ends of the push plate 31 to drive the movement of the push plate 31. The introduction of the protective structure 3 effectively eliminates the risk of the operator's arm being squeezed during the stamping process, significantly improving production safety. Due to the automated design of the protective structure 3, the arm can be ejected without human intervention, thereby ensuring the continuity and efficiency of the production line. During the operation of the continuous stamping die, when the movable mold 2 begins to descend, the hinge plate 33 rotates accordingly. Because the hinge plate 33 is hinged to both ends of the push plate 31, the rotation of the hinge plate 33 drives the push plate 31 to move. If an operator's arm accidentally gets between the fixed die 1 and the movable die 2, the push plate 31 will promptly push it out, preventing the arm from being crushed. Once the movable die 2 completes stamping and rises, the hinge plate 33 and push plate 31 return to their initial positions, ready for the next round of stamping. The introduction of this innovative protective structure 3 improves production safety in the continuous die for stamping automotive seat leaf spring brackets, while also ensuring production efficiency and convenient equipment maintenance.
[0023] Specifically, to facilitate the movement of the push plate 31, the guide member 32 comprises a guide rail 321 fixed to the fixed die 1, and a slider 322 slidably mounted on the guide rail 321 and hingedly connected to the hinge plate 33. The cooperation between the guide rail 321 and the slider 322 effectively guides and supports the push plate 31 during its movement, preventing safety hazards caused by shaking or deviation. During the stamping process, when the movable die 2 begins to descend, the hinge plate 33 rotates accordingly. Because the hinge plate 33 is hingedly connected to the slider 322, the rotation of the hinge plate 33 drives the slider 322 to slide on the guide rail 321, thereby moving the push plate 31. If an operator's arm accidentally gets between the fixed die 1 and the movable die 2, the push plate 31 will promptly push it out, preventing the arm from being squeezed. Once the movable die 2 completes stamping and ascends, the hinge plate 33 and the push plate 31 return to their initial positions, ready for the next round of stamping. By introducing the guiding mechanism of the guide rail 321 and the slider 322 , the protective structure 3 of the stamping continuous die for the automobile seat leaf spring bracket is further optimized, its stability and reliability are improved, and a safer production environment is provided for the operator.
[0024] More specifically, to facilitate the connection between the slider 322 and the push plate 31, a bracket plate 3221 fixedly connected to the push plate 31 is bolted to the slider 322. The introduction of the bracket plate 3221 further strengthens the connection between the slider 322 and the push plate 31, avoiding safety hazards caused by a loose connection. During the stamping process, when the movable mold 2 begins to descend, the hinge plate 33 rotates accordingly. Because the hinge plate 33 is hinged to the slider 322, the rotation of the hinge plate 33 drives the slider 322 to slide on the guide rail 321. At this time, the bracket plate 3221 acts as a connecting bridge, converting the sliding of the slider 322 into movement of the push plate 31. By introducing the bracket plate 3221 as a connecting bridge between the slider 322 and the push plate 31, the protective structure 3 of the automobile seat leaf spring bracket stamping continuous die is further optimized, improving its connection stability and reliability, and providing a safer and more reliable production environment for the operator.
[0025] Specifically, to reduce wear on the hinged plate 33 during use, a bearing 331 is installed at the hinge joint of the hinged plate 33. The introduction of the bearing 331 significantly reduces friction and wear on the hinged plate 33 during the hinge process, extending its service life and reducing wear-related failure rates. The introduction of the bearing 331 improves the stability and reliability of the hinged plate 33 during the hinge process, ensuring the stability and safety of the protective structure 3 during extended use. During the stamping process, when the movable die 2 begins to descend, the hinged plate 33 rotates accordingly. At this point, the bearing 331 provides critical support and lubrication at the hinge joint, effectively reducing friction and wear during the hinge process. Due to its low coefficient of friction and wear rate, the bearing 331 ensures stable performance and a long service life of the hinged plate 33 during prolonged, high-frequency rotation. Furthermore, the design of the bearing 331 takes into account the high loads and frequent movements during the stamping process, ensuring that it can withstand significant radial and axial loads, thereby ensuring the stability and reliability of the protective structure 3 during the stamping process. By introducing the bearing 331 as the wear-resistant optimization design of the hinged joint of the hinged plate 33, the stability and reliability of the protective structure 3 of the stamping continuous die of the automobile seat leaf spring bracket are further improved, the maintenance cost is reduced, and a safer and more reliable production environment is provided for the operator.
[0026] Furthermore, to maintain the hinged plate 33 in a tilted position, a buffer mechanism 4 is provided on the guide member 32. This buffer mechanism 4 comprises a fixed seat 41 fixedly mounted on the guide rail 321, a movable seat 42 slidingly mounted on the guide rail 321 between the corresponding slider 322 and the fixed seat 41, and a buffer spring 43 disposed between the fixed seat 41 and the movable seat 42. The introduction of the buffer mechanism 4 ensures that the hinged plate 33 is always in an ideal tilted position during the stamping process, avoiding safety hazards caused by shaking or deviation. The elasticity and restoring force of the buffer spring 43 compensate for deformation caused by the stamping load, thereby ensuring the stability and reliability of the protective structure 3 during long-term use. During the stamping process, when the movable die 2 begins to descend, the hinged plate 33 rotates accordingly, driving the slider 322 to slide on the guide rail 321. When the slider 322 contacts the movable seat 42, the buffer mechanism 4 begins to function. Due to the elasticity and restoring force of the buffer spring 43, the sliding of the movable seat 42 on the guide rail 321 is subject to a certain resistance, thus ensuring that the hinge plate 33 does not tilt excessively or deviate from the ideal position due to inertia during rotation. At the same time, the buffer spring 43 can also compensate for the deformation caused by the stamping load, ensuring that the hinge plate 33 always maintains a stable tilted state during the stamping process. Once the movable mold 2 completes the stamping and rises, the hinge plate 33 will return to its initial position, and the buffer mechanism 4 will also return to its initial state, preparing for the next round of stamping. By introducing the buffer mechanism 4 as an optimized design for maintaining the tilted state of the hinge plate 33, the stability and reliability of the protective structure 3 of the continuous stamping die for the leaf spring bracket of the automobile seat are further improved, providing a safer and more reliable production environment for the operator.
[0027] Furthermore, to prevent deformation caused by uneven force on the buffer spring 43, a guide rod 5 is slidably inserted into the fixed seat 41, extending into the buffer spring 43 and fixedly connected to the movable seat 42. A baffle 51 is fixedly connected to the end of the guide rod 5 facing away from the movable seat 42. The combined structure of the guide rod 5 and baffle 51 ensures balanced force distribution on the buffer spring 43, preventing deformation and failure caused by uneven force distribution. The introduction of the guide rod 5 and baffle 51 enhances the overall structural stability of the buffer mechanism 4 and improves the impact resistance of the protective structure 3 during the stamping process. Because the force distribution on the buffer spring 43 is balanced, wear and fatigue caused by deformation are reduced, thereby extending the service life of the buffer mechanism 4 and the entire protective structure 3. During the stamping process, when the movable die 2 begins to descend, the hinged plate 33 rotates accordingly, driving the slider 322 and movable seat 42 to slide on the guide rail 321. At this point, the buffer spring 43 begins to compress. However, the presence of the guide rod 5 and baffle 51 makes the compression process of the buffer spring 43 more uniform and controllable. The guide rod 5 ensures that the buffer spring 43 maintains a stable shape and position when compressed, avoiding deformation caused by uneven force. At the same time, the baffle 51 acts as a limiting component for the buffer spring 43, preventing the buffer spring 43 from excessively deforming or failing when subjected to excessive compression. Therefore, during the compression and recovery process of the buffer spring 43, the combined structure of the guide rod 5 and the baffle 51 ensures the stability and reliability of the buffer mechanism 4, thereby improving the overall performance of the protective structure 3 during the stamping process. Once the movable mold 2 completes the stamping and rises, the hinged plate 33, the slider 322, and the movable seat 42 will return to their initial positions, and the buffer spring 43 will also return to its initial state, preparing for the next round of stamping. By introducing the combined structure of the guide rod 5 and the baffle 51 as an optimized design for balanced force on the buffer spring 43, the stability and reliability of the protective structure 3 of the continuous stamping die for the leaf spring bracket of the automobile seat are further improved, providing a safer and more reliable production environment for the operator.
