A stamping mechanism

Abstract

The application provides a stamping mechanism, which comprises a stabilizing seat, a connecting piece penetrating through the stabilizing seat, a driving assembly and a stamping assembly. The driving assembly and the stamping assembly are like scales at two ends of the connecting piece, and the motion is synchronous and reverse, thus forming an internal symmetrical guiding system, and the stabilizing seat and the connecting piece form a fulcrum. The power is symmetrically transmitted through the central rocker arm, so that the force acting on the stamping rod and the driving rod is mainly in the axial direction, the lateral force of the guiding structure is reduced, the abrasion is reduced from the source, and the high centering precision can be maintained for a long time. Even if there is a small gap in the sliding pair, the synchronous action of the rocker arm can also ensure that the relative position of the stamping part and the driving source is rigidly determined, and the single guide rail will not be out of alignment due to abrasion.

Description

Technical Field

[0001] This application relates to the field of injection molding, and more particularly to a stamping mechanism. Background Technology

[0002] In traditional stamping mechanisms, the enormous stamping force is entirely borne and offset by the machine body guide rails. After prolonged use, the guide rails inevitably wear down, creating gaps. Once these gaps appear, the slide will experience slight wobble or deflection during the stamping process.

[0003] Such minute deviations can lead to serious problems: for example, the alignment of the punch and die is disrupted, and the upper and lower dies cannot be precisely aligned. This can result in excessive clearance on one side of the die and insufficient clearance on the other side, or even collisions, accelerating uneven wear of the die and potentially causing chipping or breakage, leading to extremely high repair costs. Moreover, poor equipment stability manifests as the need for frequent adjustments and repairs to the guide rails after a decrease in precision, affecting production efficiency and equipment reliability.

[0004] Therefore, a stamping mechanism with improved stability is needed. Utility Model Content

[0005] In view of this, it is necessary to provide a stamping mechanism with improved stability to solve the above problems.

[0006] Embodiments of this application provide a stamping mechanism, including: Stable mount; Connector, penetrating the stabilizer; A drive assembly is connected to one end of the connector and located on one side of the stabilizer, and slides along the height direction of the stabilizer; A stamping assembly is connected to the other end of the connector and located on the other side of the stabilizing seat, and the stamping assembly slides synchronously with the driving assembly.

[0007] In at least one embodiment of this application, the driving component includes: The drive seat is fixedly connected to the stabilizer seat; A drive rod is arranged along the height direction of the stabilizer, and is positioned opposite and spaced apart from the stabilizer. One end of the drive rod is slidably connected to the drive seat, and the other end of the drive rod is connected to one end of the connector.

[0008] In at least one embodiment of this application, the drive seat has a sliding cavity, the sliding cavity is arranged along the height direction of the stabilizing seat, and one end of the drive rod is attached to and slidably connected to the sliding cavity.

[0009] In at least one embodiment of this application, the stamping assembly includes: A stamping rod is provided along the height direction of the stabilizer and is positioned opposite and spaced apart from the stabilizer. One end of the stamping rod is connected to the other end of the connector. The stamped part is connected to the other end of the stamping rod.

[0010] In at least one embodiment of this application, the stamping rod and the drive rod are located on opposite sides of the stabilizing seat.

[0011] In at least one embodiment of this application, the stamped part includes: The punch is connected to the other end of the stamping rod; The die is connected to the end of the punch away from the stamping rod and has a stamping cavity.

[0012] In at least one embodiment of this application, the stabilizing seat has a connecting hole that extends through the stabilizing seat and is located at the end away from the stamping part.

[0013] In at least one embodiment of this application, the connector is configured as a rocker arm.

[0014] In at least one embodiment of this application, the connector further includes: The two connecting parts are respectively fixedly connected to the driving assembly and the stamping assembly.

[0015] In at least one embodiment of this application, the connector further includes: A fixed shaft is located between the two connecting parts, and the fixed shaft passes through the connecting member and is fixedly connected to the stabilizing seat.

[0016] The aforementioned stamping mechanism, with its drive assembly and stamping assembly resembling two weighing pans at either end of a connector, ensures that their movements are always synchronous and opposite. This constitutes an inherent, symmetrical guiding system. The stabilizing seat and the connector passing through it form the system's fulcrum.

[0017] Furthermore, since the power is transmitted symmetrically through the central rocker arm, the force acting on the stamping rod and drive rod is mainly in the axial direction, greatly reducing the lateral force acting on the guide structure. This reduces wear on the guide components from the source and maintains extremely high alignment accuracy over a long period.

[0018] Furthermore, even if there are minute gaps in the sliding pairs of the drive rod and the stamping rod, the relative positional relationship between the stamping part and the drive source is rigid and definite due to the forced synchronization effect of the rocker arm, and will not become inaccurate due to the wear of a single guide rail.

[0020] The embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0021] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or may also have an intervening component.

[0022] Embodiments of this application provide a stamping mechanism, including: Stable mount; Connector, penetrating the stabilizer; A drive assembly is connected to one end of the connector and located on one side of the stabilizer, and slides along the height direction of the stabilizer; A stamping assembly is connected to the other end of the connector and located on the other side of the stabilizing seat, and the stamping assembly slides synchronously with the driving assembly.

[0023] The aforementioned stamping mechanism, with its drive assembly and stamping assembly resembling two weighing pans at either end of a connector, ensures that their movements are always synchronous and opposite. This constitutes an inherent, symmetrical guiding system. The stabilizing seat and the connector passing through it form the system's fulcrum.

[0024] Furthermore, since the power is transmitted symmetrically through the central rocker arm, the force acting on the stamping rod and drive rod is mainly in the axial direction, greatly reducing the lateral force acting on the guide structure. This reduces wear on the guide components from the source and maintains extremely high alignment accuracy over a long period.

[0025] Furthermore, even if there are minute gaps in the sliding pairs of the drive rod and the stamping rod, the relative positional relationship between the stamping part and the drive source is rigid and definite due to the forced synchronization effect of the rocker arm, and will not become inaccurate due to the wear of a single guide rail.

[0026] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0027] Please see Figures 1-4 The embodiments of this application provide a stamping mechanism 100, including: a stabilizing seat 10, a connecting member 20, a driving assembly 30 and a stamping assembly 40.

[0028] The connector 20 passes through the stabilizer 10. The drive assembly 30 is connected to one end of the connector 20 and is located on one side of the stabilizer 10, sliding along the height direction of the stabilizer 10. The stamping assembly 40 is connected to the other end of the connector 20 and is located on the other side of the stabilizer 10, and the stamping assembly 40 slides synchronously with the drive assembly 30.

[0029] Specifically, the stamping mechanism 100 consists of a stabilizing seat 10, a connecting member 20 passing through the stabilizing seat 10, a drive assembly 30 located on both sides of the stabilizing seat 10 and reciprocating linearly along its height, and a stamping assembly 40. The stabilizing seat 10 serves as the basic support structure of the entire stamping mechanism 100, stabilizing the whole and providing a stable platform for the installation and operation of other components. The connecting member 20 passes through the stabilizing seat 10, acting like a bridge connecting the drive assembly 30 and the stamping assembly 40, and is the key connection hub for the coordinated movement of the entire mechanism.

[0030] Furthermore, the connector 20 is a rod-shaped structure that runs through the channel of the stabilizer 10, with its two ends extending out from both sides of the stabilizer 10, thereby connecting the stamping mechanism 100 and the drive mechanism. The power input end of the drive assembly 30 can be connected to a power source such as a hydraulic cylinder or a servo motor, and the power output direction is completely consistent with the height direction, ensuring that the power can be transmitted along the axial direction of the connector 20.

[0031] Furthermore, the drive assembly 30 is connected to one end of the connector 20 and is located on one side of the stabilizer 10. During operation, the drive assembly 30 can slide along the height direction of the stabilizer 10. This sliding is achieved through a specific power input, such as a power source like a motor driving the relevant transmission components, thereby causing the drive assembly 30 to reciprocate in the vertical direction.

[0032] Furthermore, the stamping assembly 40 is connected to the other end of the connector 20, located on the other side of the stabilizing seat 10. The stamping assembly 40 slides synchronously with the drive assembly 30, much like two weighing pans at both ends of the connector 20. While the drive assembly 30 moves, the stamping assembly 40 moves in the same rhythm but in the opposite direction. This synchronous and reverse motion pattern constitutes the unique inherent, symmetrical guiding system of the stamping mechanism 100. The stabilizing seat 10 and the connector 20 that passes through it together form the fulcrum of this system, providing mechanical support for the stable operation of the entire mechanism, allowing the movement of the drive assembly 30 and the stamping assembly 40 to proceed in an orderly manner around this fulcrum.

[0033] In one specific embodiment, the driving component 30 includes: The drive seat 31 is fixedly connected to the stabilizer seat 10; The drive rod 32 is arranged along the height direction of the stabilizer 10 and is opposite to and spaced apart from the stabilizer 10. One end of the drive rod 32 is slidably connected to the drive seat 31, and the other end of the drive rod 32 is connected to one end of the connector 20.

[0034] Specifically, the drive mount 31 and the stabilizer mount 10 are fixedly connected, such as by bolts, to provide precise and highly rigid guiding support for the drive rod 32. The drive mount 31 securely mounts the main body of the drive assembly 30 onto the stabilizer mount 10, which serves as a reference platform.

[0035] Furthermore, the drive rod 32 is the actuator for power transmission. It is positioned along the height direction of the stabilizer 10, i.e., the stamping direction, and one end of it is slidably connected to the drive seat 31, thereby ensuring that the drive rod 32 can only move linearly along its axial direction, while greatly restricting the degrees of freedom in other directions.

[0036] Furthermore, one end of the drive rod 32 is slidably connected to the drive seat 31. This sliding connection allows the drive rod 32 to reciprocate flexibly in a specific direction on the drive seat 31. In this embodiment, the sliding connection is achieved through a structure such as a groove, ensuring that the drive rod 32 experiences low friction and smooth, stable movement during motion. The other end of the drive rod 32 is connected to one end of the connector 20, which transmits the motion of the drive rod 32 to the stamping assembly 40, achieving linkage between the drive assembly 30 and the stamping assembly 40, thereby completing the working cycle of the entire stamping mechanism 100.

[0037] In summary, when the stamping mechanism 100 is operating, the power generated by the drive source of the drive mechanism is transmitted to the drive rod 32. When the power source pushes the drive rod 32 downward, the force is instantly converted into an equal and opposite force through the lever action of the connecting member 20, pushing the stamping rod 41 at the other end of the connecting member 20 upward to complete the stamping action. Therefore, the movements of the drive assembly 30 and the stamping assembly 40 are always synchronous and opposite, and their displacements and accelerations are always mirror images of each other. This avoids the dispersion and loss of power during transmission, improves power transmission efficiency, and enables the stamping mechanism 100 to achieve greater stamping force with less energy input, thus reducing energy consumption.

[0038] In one specific embodiment, the drive seat 31 has a sliding cavity 311, which is arranged along the height direction of the stabilizing seat 10, and one end of the drive rod 32 is attached to and slidably connected to the sliding cavity 311.

[0039] Specifically, the sliding cavity 311 is a hole or channel machined along the height direction of the stabilizer 10. Its cross-sectional shape matches the cross-section of one end of the drive rod 32, and is usually circular, square, or other regular geometric shape. One end of the drive rod 32 is embedded and accommodated in this sliding cavity 311, and its outer wall is in sliding fit with the inner wall of the sliding cavity 311, thereby achieving a tight, surface-contact sliding connection.

[0040] Furthermore, one end of the drive rod 32 is fitted and slidably connected to the sliding cavity 311, which effectively restricts the degree of freedom of the drive rod 32 in directions other than height, preventing instability such as swaying or deflection during movement. Simultaneously, the sliding connection design ensures smooth sliding of the drive rod 32 within the sliding cavity 311, reducing frictional resistance during movement, making power transmission more efficient, and reducing energy loss.

[0041] In one specific embodiment, the stamping assembly 40 includes: A stamping rod 41 is arranged along the height direction of the stabilizer 10 and is opposite to and spaced apart from the stabilizer 10. One end of the stamping rod 41 is connected to the other end of the connector 20. The stamping part 42 is connected to the other end of the stamping rod 41.

[0042] Specifically, the stamping rod 41 serves as the force transmission bridge for the stamping assembly 40. The stamping rod 41 is positioned opposite and spaced apart from the stabilizer 10. This spacing is precisely calculated and designed to provide ample space for the movement of the stamping rod 41, preventing interference with the stabilizer 10 during reciprocating motion and affecting normal operation. Simultaneously, the stabilizer 10 helps to constrain and guide the movement of the stamping rod 41 to a certain extent, preventing excessive deviation or swaying and ensuring stability.

[0043] Furthermore, one end of the stamping rod 41 is connected to the other end of the connecting member 20. The connecting member 20, as a key transmission component between the drive assembly 30 and the stamping assembly 40, transmits the movement of the drive rod 32 to the stamping rod 41. This connection method needs to have sufficient strength and rigidity to withstand the huge forces generated during the stamping process, ensuring the continuity and reliability of power transmission. The stamping part 42 is connected to the other end of the stamping rod 41. The stamping part 42 is a component that directly acts on the material being processed. Its shape and size are designed according to the specific stamping process and product requirements. Driven by the stamping rod 41, the stamping part 42 can apply precise stamping force to the material to complete various stamping forming operations.

[0044] Furthermore, in terms of power transmission, the connector 20 efficiently transmits the power of the drive rod 32 to the stamping rod 41. The power generated by the drive rod 32 during its movement is transmitted to the stamping rod 41 with almost no loss through the rigid connection of the connector 20, enabling the stamping rod 41 to obtain sufficient power to drive the stamped part 42 to perform the stamping operation. This efficient power transmission method ensures that the stamping mechanism 100 can achieve a large stamping force output with a small energy input, improving energy utilization efficiency and reducing production costs. At the same time, because the power transmission process is stable and reliable, stamping failures caused by power interruption or fluctuation are reduced, enhancing the operational stability of the equipment.

[0045] In summary, the drive rod 32 and the stamping rod 41 in the drive assembly 30 are connected by the connector 20, and the movements of the drive assembly 30 and the stamping assembly 40 are always synchronized and opposite, with the stamping rod 41 moving in sync with the drive rod 32. When the drive rod 32 reciprocates linearly along the height of the stabilizer 10 within the sliding cavity 311 of the drive seat 31, the stamping rod 41 also moves synchronously in the same direction. This high degree of motion coordination ensures the accuracy and consistency of the stamping process. Whether in the initial, ongoing, or final stage of stamping, the stamping part 42 can accurately reach the predetermined position and apply appropriate stamping force to the material, thereby producing stamped products with stable quality and precise dimensions, greatly improving the product qualification rate.

[0046] In one specific embodiment, the stamping rod 41 and the driving rod 32 are located on both sides of the stabilizing seat 10.

[0047] Specifically, by placing the stamping rod 41 and the drive rod 32 on both sides of the stabilizer 10, the structural strength of the stabilizer 10 can be fully utilized, making the force distribution more uniform and reasonable. This avoids the stabilizer 10 from being deformed or damaged due to excessive local stress caused by the force being concentrated on one side, thereby ensuring the stability and reliability of the entire stamping mechanism 100 under long-term high-load operation.

[0048] Furthermore, during the stamping process, the drive rod 32 generates power under the action of the drive source, and transmits the force to the stamping rod 41 through the connector 20. The stamping rod 41 then drives the stamping part 42 to apply stamping force to the material. When the stamping rod 41 and the drive rod 32 are located on both sides of the stabilizing seat 10, the stabilizing seat 10 can act like a symmetrical mechanical support structure, evenly distributing the power transmitted by the drive rod 32 and the reaction force received by the stamping rod 41 to its various parts.

[0049] In one specific embodiment, the stamped part 42 includes: The punch 421 is connected to the other end of the stamping rod 41; The die 422 is connected to the end of the punch 421 away from the stamping rod 41 and has a stamping cavity 423.

[0050] Specifically, the punch 421 is connected to the other end of the stamping rod 41, ensuring that the punch 421 can receive power from the stamping rod 41 and convert the linear motion of the stamping rod 41 into a stamping action on the material. The punch 421 is the component that directly acts on the material, and the stamping cavity 423 opened on the die 422 is the final area for receiving the material and performing stamping or separation.

[0051] Furthermore, during the stamping process, the material is placed between the punch 421 and the die 422. When the punch 421 moves downward under the action of the stamping rod 41, the material is pressed into the stamping cavity 423 of the die 422, where it undergoes plastic deformation under the stamping force, thus forming a product with a shape consistent with the stamping cavity 423. This cooperative design of the punch 421 and the die 422 ensures the dimensional accuracy and shape consistency of the stamped product, thereby improving product quality.

[0052] In one specific embodiment, the stabilizing base 10 has a connecting hole 11 that penetrates the stabilizing base 10 and is located at the end away from the stamping part 42.

[0053] In one specific embodiment, the connector 20 is configured as a rocker arm.

[0054] Specifically, the connecting hole 11 is used to accommodate the connecting member 20, so that the connecting member 20, which is a swing arm, can swing smoothly and without wobbling within the connecting hole 11. The other end of the connecting member 20 is connected to the stamping rod 41. As the connecting member 20 swings, the stamping rod 41 will reciprocate linearly under the push of the connecting member 20 to realize the stamping action.

[0055] In one specific embodiment, the connector 20 further includes: The two connecting parts 21 are respectively fixedly connected to the driving assembly 30 and the stamping assembly 40.

[0056] Specifically, the connecting part 21 serves as a key connection hub, fixing the drive assembly 30 and the stamping assembly 40 together. This is typically achieved through methods such as threaded connections, flange bolt fastening, wedge block locking, or spline fit, forming a rigid whole. The connecting part 21 also needs to ensure the smoothness of power transmission, preventing fluctuations or impacts during power transmission from adversely affecting the stamping assembly 40, thereby ensuring the stable quality of the stamped products.

[0057] Furthermore, the drive source is transmitted directly from the drive rod 32 to the connecting part 21 of the rocker arm, and then directly to the stamping rod 41 through the connecting part 21 of the other end of the connecting part 20. The entire force flow path is a completely rigid whole, ensuring that the stamping force is transmitted most effectively and directly, further improving energy utilization efficiency and stamping stability.

[0058] In one specific embodiment, the connector 20 further includes: A fixed shaft 22 is located between the two connecting parts 21, and the fixed shaft 22 passes through the connecting member 20 and is fixedly connected to the stabilizing seat 10.

[0059] Specifically, the fixed shaft 22 is located at the center between the connecting parts 21 at both ends of the rocker arm and extends through the rocker arm body. As a stable rotation center and support point, the fixed shaft 22 can reasonably distribute and transmit the various forces from the drive assembly 30 and the stamping assembly 40 borne by the two connecting parts 21.

[0060] Furthermore, both ends of the fixed shaft 22 are fixedly connected to the stabilizing seat 10, so that the fixed shaft 22 itself is stationary relative to the stabilizing seat 10. The connector 20 body is mounted on the fixed shaft 22 by bearings and other mechanisms, and can rotate freely around the axis of the fixed shaft 22.

[0061] Therefore, the aforementioned stamping mechanism 100, through the drive assembly 30 and the stamping assembly 40 acting like two weighing pans at both ends of the connector 20, ensures that the movements of the drive assembly 30 and the stamping assembly 40 are always synchronous and opposite, forming an inherent, symmetrical guiding system. The stabilizer 10 and the connector 20 passing through it constitute the fulcrum of the system.

[0062] Furthermore, since the power is transmitted symmetrically through the central rocker arm, the force acting on the stamping rod 41 and the drive rod 32 is mainly in the axial direction, greatly reducing the lateral force acting on their guide structure. This reduces the wear of the guide components from the source and maintains extremely high alignment accuracy over a long period of time.

[0063] Furthermore, even if there are minute gaps in the sliding pairs of the drive rod 32 and the stamping rod 41, the relative positional relationship between the stamping part 42 and the drive source is rigid and definite due to the forced synchronization effect of the rocker arm, and will not become inaccurate due to the wear of a single guide rail.

[0064] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
