Description

Technical Field

[0001] This invention relates to the field of automotive shock absorber stamping equipment technology, specifically to a continuous stamping device for the production of automotive shock absorbers. Background Technology

[0002] Automotive shock absorber pads are key components of automotive shock absorber systems. Their processing involves core processes such as sheet metal cutting, continuous stamping, and edge grinding. Among these, continuous stamping is the crucial step determining product precision and efficiency, requiring a continuous stamping device for efficient and precise processing. The closest existing patent is CN209109925U, entitled "A Continuous Stamping Device for Automotive Shock Absorber Pads." This device can stamp multiple parts simultaneously, with convenient mold replacement and automatic calibration. However, it does not solve the problem of manual placement of sheet metal during feeding, posing a safety hazard. Furthermore, it lacks optimized sheet metal conveying limits and adaptive clamping structures, making it prone to sheet metal misalignment and unstable clamping, affecting production efficiency and stamping accuracy. Therefore, there is an urgent need for a continuous stamping device that balances safety, efficiency, and precision. Summary of the Invention

[0003] The present invention aims to solve one of the technical problems existing in the prior art.

[0004] This application provides a continuous stamping device for the production of automotive shock absorbers, including an operating table, a top frame, a hydraulic rod, an upper die, a lower die, and a sheet metal conveying device. The sheet metal conveying device is used to clamp and convey sheet metal, and includes a reciprocating drive assembly and a pair of adaptive clamps. The reciprocating drive assembly is used to drive the pair of adaptive clamps to reciprocate towards or away from the upper die and the lower die. When the adaptive clamps move away from the upper die and the lower die, they clamp and drag the sheet metal according to the thickness of the sheet metal, and when they move towards the upper die and the lower die, they release the sheet metal.

[0005] Furthermore, the adaptive fixture includes a clamping unit, a transmission unit, and a clamping control unit. The clamping unit is fixed on the reciprocating drive assembly and includes a pair of clamping blocks. The clamping control unit is disposed on the operating table. The transmission unit is movably mounted on the clamping unit and is connected to the clamping control unit in a transmission manner. When the clamping unit moves away from the upper and lower molds, the transmission unit and the clamping control unit cooperate to drive the pair of clamping blocks to adaptively clamp and drag the plate. When the clamping unit approaches the upper and lower molds, the transmission unit and the clamping control unit cooperate to release the clamping blocks from clamping the plate.

[0006] Furthermore, the clamping unit also includes a clamping block, a clamping groove, and a pair of L-shaped grooves. The clamping block is fixed on the reciprocating drive assembly. The clamping groove is opened inside the clamping unit. The pair of L-shaped grooves are both disposed inside the clamping block. The inner ends are respectively connected to the upper and lower surfaces of the clamping grooves, and the outer ends are connected to the outer side wall of the clamping block. The transmission unit is U-shaped with both ends facing inward and is airtightly slidably installed in the pair of L-shaped grooves. Each clamping block is airtightly slidably installed at the inner end of each L-shaped groove and extends into the clamping groove.

[0007] Furthermore, the transmission unit includes a vertical plate, a pair of horizontal plates, a pair of conductive components, a lifting slide groove, and a lifting transmission component. The vertical plate and the pair of horizontal plates are connected to each other in a U-shape. The inner ends of the pair of horizontal plates are airtightly slidably installed in corresponding L-shaped grooves and are provided with airtight slide grooves. The pair of conductive components are airtightly slidably installed in each airtight slide groove. The lifting slide groove is opened on the outer wall of the vertical plate. The lifting transmission component is slidably installed in the lifting slide groove and is connected to the clamping control unit. A spring is provided between the inner side of the vertical plate and the outer side of the clamping block.

[0008] Furthermore, the clamping control unit includes a side plate and a loop groove. The side plate is fixed on the operating table. The lifting transmission component slides in conjunction with the loop groove. The loop groove is trapezoidal and is formed on the side plate. The loop groove includes a return groove, a pressing groove, and a pair of oblique grooves. The depth of the return groove is greater than that of the pressing groove. The pair of oblique grooves connect the two ends of the return groove and the pressing groove, respectively.

[0009] Furthermore, the return groove also includes a guide block, which is disposed at one end of the pressing groove near the upper and lower molds, for guiding the lifting sliding component into the inclined groove near the upper and lower molds. The lower end of the inclined groove away from the upper and lower molds maintains a 5mm gap with the bottom of the return groove, for preventing the lifting transmission component from entering the inclined groove during the retraction process.

[0010] Furthermore, the lifting transmission component includes a lifting slider and a sliding column that are fixedly connected to each other. The lifting slider is slidably engaged with the lifting groove, and the sliding column is slidably engaged with the loop groove.

[0011] Furthermore, the reciprocating drive assembly includes a mounting cavity, a load-bearing slide plate, a rotating column, a cone block, a lifting component, a drive component, and a transmission slide plate. The mounting cavity is located at the bottom of the operating table. The load-bearing slide plate is slidably mounted on the top surface of the operating table to support the adaptive clamp. The transmission slide plate is slidably mounted in the mounting cavity. The rotating column is rotatably mounted on the operating table and extends into the mounting cavity, and is connected to the load-bearing slide plate and the transmission slide plate through a pair of sliding pairs. The cone block is rotatably mounted in the mounting cavity through the drive component and has a vertical surface on one side for driving the transmission slide plate to slide horizontally back and forth. The lifting component is used to control the lifting and lowering of the cone block.

[0012] Furthermore, the lifting component includes a lifting shell, a lifting bracket, and an adjusting bolt. The lifting shell is fixed to one side of the operating table and communicates with the mounting cavity. The lifting bracket is slidably installed in the mounting cavity. The cone block is rotatably installed at the inner end of the lifting bracket. The adjusting bolt is rotatably installed in the lifting shell and is connected to the outer end of the lifting bracket through a screw hole.

[0013] Furthermore, the driving component includes a motor and a polygonal drive shaft. The motor is mounted at the bottom of the mounting cavity, and the polygonal drive shaft is mounted on the output shaft of the motor and slides through the cone block along the central axis of the cone block.

[0014] The beneficial effects of this invention are as follows: 1. By cooperating with the reciprocating drive component and the adaptive fixture, the reciprocating drive component drives the adaptive fixture to move back and forth. The clamping unit, transmission unit and clamping control unit of the adaptive fixture are linked together. When it is far away from the stamping station, it adaptively clamps the sheet metal and releases it when it is close to the station, realizing automatic sheet metal conveying without manual intervention, ensuring the safety of operators and improving feeding efficiency. 2. By cooperating with the L-shaped groove and T-shaped clamping block of the clamping unit and the airtight structure and floating plate of the transmission unit, the floating plate adaptively floats according to the thickness of the sheet metal, and the airtight structure pushes the clamping block to stably clamp the sheet metal, so as to realize the adaptive clamping of sheet metal of different thicknesses, avoid the sheet metal being damaged by excessive clamping or slipping due to excessive loose clamping, and ensure stamping accuracy. 3. By using the loop groove of the clamping control unit, the conductive plate, the lifting transmission component, and the electrorheological fluid in conjunction, the sliding column slides along the loop groove, causing the sliding column to contact / separate from the conductive plate. This controls the electrorheological fluid to lock / unlock the clamping block, ensuring stable clamping during the conveying process and avoiding false linkage during reset, thus improving the stability of the device operation. 4. Through the cooperation of the cone block, transmission slide plate, rotating column and sliding pair of the reciprocating drive component, the cone block rotates to drive the transmission slide plate to slide back and forth, and the rotating column and sliding pair drive the load slide plate to move. Combined with the lifting component to adjust the height of the cone block, the feeding stroke can be flexibly adjusted to adapt to the processing of different specifications of shock-absorbing plates and expand the application range of the device.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0019] The continuous stamping apparatus for producing automotive shock absorbers provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0020] Example 1: This application provides a continuous stamping device for producing automotive shock absorbers, including an operating table 1, a top frame 2, a hydraulic rod 3, an upper die 4, a lower die 5, and a sheet metal conveying device. The sheet metal conveying device is used to clamp and convey sheet metal, and includes a reciprocating drive assembly 6 and a pair of adaptive clamps. The reciprocating drive assembly 6 is used to drive the pair of adaptive clamps to reciprocate towards or away from the upper die 4 and the lower die 5. When the adaptive clamps move away from the upper die 4 and the lower die 5, they clamp and drag the sheet metal according to the thickness of the sheet metal; when they move towards the upper die 4 and the lower die 5, they release the sheet metal.

[0021] In this embodiment of the application, the adaptive fixture includes a clamping unit 7, a transmission unit 8, and a clamping control unit 9. The clamping unit 7 is fixed on the reciprocating drive assembly 6 and includes a pair of clamping blocks 71. The clamping control unit 9 is disposed on the operating table 1. The transmission unit 8 is movably mounted on the clamping unit 7 and is connected to the clamping control unit 9 in a transmission manner. When the clamping unit 7 is away from the upper mold 4 and the lower mold 5, the transmission unit 8 and the clamping control unit 9 cooperate to drive the pair of clamping blocks 71 to adaptively clamp and drag the plate. When the clamping unit 7 is close to the upper mold 4 and the lower mold 5, the transmission unit 8 and the clamping control unit 9 cooperate to release the clamping of the pair of clamping blocks 71 on the plate.

[0022] like Figures 1 to 9 As shown, due to the above structure, when moving the sheet metal, the reciprocating drive assembly 6 is first activated, which drives the clamping unit 7 (including a pair of clamping blocks 71) and the transmission unit 8 fixed on it to move synchronously away from the upper mold 4 and the lower mold 5. Then, the transmission unit 8 works in conjunction with the clamping control unit 9 on the operating table 1 to drive the pair of clamping blocks 71 to adaptively clamp the sheet metal according to the sheet metal thickness. After clamping, the reciprocating drive assembly 6 drives the adaptive fixture to move away from the stamping station in the opposite direction, dragging the sheet metal to the stamping station accurately. When the clamping unit 7 moves to the stamping station, the cooperation state between the transmission unit 8 and the clamping control unit 9 changes, and the clamping blocks 71 release the sheet metal, completing the sheet metal moving process.

[0023] During reset, after the sheet material is fed, the reciprocating drive assembly 6 starts the reset program, driving the adaptive fixture to move towards the stamping station. At this time, the transmission unit 8 and the clamping control unit 9 remain in a disengaged state, and the clamping block 71 never contacts the sheet material. As the reciprocating drive assembly 6 continues to drive the clamping unit 7 and the transmission unit 8 to move towards the initial position, the transmission unit 8 gradually restores the initial engagement state with the clamping control unit 9 until all components return to the initial position away from the stamping station, and the clamping block 71 is in a ready-to-clamp state, completing the reset process.

[0024] Example 2: In this embodiment, in addition to the structural features of the aforementioned embodiments, the clamping unit 7 further includes a clamping block 72, a clamping groove 73, and a pair of L-shaped grooves 74. The clamping block 72 is fixed on the reciprocating drive assembly 6. The clamping groove 73 is formed inside the clamping unit 7. The pair of L-shaped grooves 74 are both disposed inside the clamping block 72. The inner ends of the L-shaped grooves 73 are respectively connected to the upper and lower surfaces of the clamping grooves 73, and the outer ends are connected to the outer side wall of the clamping block 72. The transmission unit 8 is U-shaped with both ends facing inward and is airtightly slidably installed in the pair of L-shaped grooves 74. Each clamping block 71 is airtightly slidably installed inside the L-shaped grooves 74 and extends into the clamping grooves 73.

[0025] In this embodiment of the application, the transmission unit 8 includes a vertical plate 81, a pair of horizontal plates 82, a pair of conductive elements 83, a lifting slide 84, and a lifting transmission element 85. The vertical plate 81 and the pair of horizontal plates 82 are connected to each other in a U-shape. The inner ends of the pair of horizontal plates 82 are airtightly slidably installed in corresponding L-shaped grooves 74 and are provided with airtight slide grooves 86. The pair of conductive elements 83 are respectively airtightly slidably installed in each airtight slide groove 86. The lifting slide 84 is opened on the outer wall of the vertical plate 81. The lifting transmission element 85 is slidably installed in the lifting slide 84 and is connected to the clamping control unit 9. A spring 85 is provided between the inner side of the vertical plate 81 and the outer side of the clamping block 72.

[0026] In this embodiment of the application, the clamping block 71 has a T-shaped cross-section, and springs 85 are provided between the top two sides and the bottom surface of the inner cavity of the L-shaped groove 74.

[0027] In this embodiment of the application, the conductive element 83 includes a floating plate 84 and a spring 85. The floating plate 84 is floatingly mounted in the airtight slide groove 86 by the spring 85. The floating stroke in the airtight slide groove 86 is affected by the thickness of the clamped plate.

[0028] like Figures 2 to 6As shown, due to the above structure, when moving the sheet metal, the reciprocating drive assembly 6 is activated, which drives the clamping block 72 and the transmission unit 8 to move away from the stamping station simultaneously. At this time, the spring 85 between the vertical plate 81 and the clamping block 72 naturally extends, the horizontal plate 82 is outside the L-shaped groove 74, and the clamping block 71 slightly extends into the clamping groove 73 to be clamped. As the clamping block 72 moves away, the lifting transmission component 85 is driven by the clamping control unit 9 to slide down along the lifting slide 84, which drives the vertical plate 81 to compress the spring 85 and the horizontal plate 82 to slide airtightly towards the clamping groove 73. The compressed gas pushes the T-shaped clamping block 71 to clamp the sheet metal. The floating plate 84 floats adaptively according to the thickness of the sheet metal. After the clamping is stable, the reciprocating drive assembly 6 continues to drive the clamping block 72 and the transmission unit 8 away from the stamping station, dragging the sheet metal to the station. When it approaches the station, the lifting transmission component 85 slides up, the vertical plate 81 and the horizontal plate 82 are reset under the action of the spring 85, the clamping block 71 is released, and the feeding is completed.

[0029] During reset, after the sheet material is fed, the reciprocating drive assembly 6 starts to reset, driving the clamping block 72 and the transmission unit 8 to move towards the stamping station. The lifting transmission component 85 slides up and disengages from the clamping control unit 9. Then, the vertical plate 81 returns to its initial position under the action of the spring 85, driving the horizontal plate 82 to slide to the outside. The clamping block 71 and the floating plate 84 reset under the action of their own springs 85, until the reciprocating drive assembly 6 drives all components to return to their initial positions. The lifting transmission component 85 and the clamping control unit 9 resume the linkage ready state, and the reset is completed.

[0030] Example 3: In this embodiment, in addition to the structural features of the aforementioned embodiments, the clamping control unit 9 includes a side plate 91 and a loop groove 92. The side plate 91 is fixed on the operating table 1. The lifting transmission component 85 is slidably engaged with the loop groove 92. The loop groove 92 is trapezoidal and is formed on the side plate 91. The loop groove 92 includes a return groove 921, a pressing groove 922, and a pair of oblique grooves 923. The depth of the return groove 921 is greater than that of the pressing groove 922. The pair of oblique grooves 923 respectively connect the two ends of the return groove 921 and the pressing groove 922.

[0031] In this embodiment of the application, the groove 92 further includes a guide block 924, which is disposed at one end of the pressing groove 922 near the upper mold 4 and the lower mold 5, for guiding the lifting sliding component into the inclined groove 923 near the upper mold 4 and the lower mold 5. The lower end of the inclined groove 923 away from the upper mold 4 and the lower mold 5 maintains a 5mm gap with the bottom of the return groove 921, for preventing the lifting transmission component 85 from entering the inclined groove 923 during the retraction process.

[0032] In this embodiment of the application, the lifting transmission component 85 includes a lifting slider 851 and a sliding column 852 that are fixedly connected to each other. The lifting slider 851 is slidably engaged with the lifting slide groove 84, and the sliding column 852 is slidably engaged with the loop groove 92.

[0033] In this embodiment of the application, a conductive plate is provided in the pressing groove 922, the outer end of the lifting slider 851 is conductive, and an electrorheological fluid is provided in the L-shaped groove 74. When the lifting slider 851 contacts the conductive plate, the electrorheological fluid is energized and transformed into a low-viscosity fluid, so that the position of the pair of clamps 71 cannot change.

[0034] like Figures 2 to 6 As shown, due to the aforementioned structure, when moving the sheet metal, the reciprocating drive assembly 6 is activated, driving the clamping block 72 and the transmission unit 8 away from the stamping station. At this time, the sliding column 852 is in the return groove 921 near the stamping station end, the lifting slider 851 separates from the conductive plate, the electrochemical fluid is de-energized, the clamping block 71 is released, and as the clamping block 72 moves away from the stamping station, the sliding column 852 slides along the return groove 921, and under the guidance of the guide block 924, it enters the inclined groove 923 near the stamping station and slides to the pressing groove 922. The lifting slider 851 is driven down and pushes the vertical plate 81 and horizontal plate 82 towards the clamping groove 73. The clamping block 71 clamps the plate. The lifting slider 851 contacts the conductive plate, which energizes the electrochemical fluid and locks the clamping block 71. The reciprocating drive assembly 6 continues to drive the clamping block 72 away from the stamping station, dragging the unstamped part of the plate into the stamping station until the sliding column 852 enters the inclined groove 923 away from the stamping station. The lifting slider 851 slides up and separates from the conductive plate. The electrochemical fluid resets and the clamping block 71 is released, completing the feeding.

[0035] During reset, after feeding is completed, the reciprocating drive assembly 6 starts resetting, driving the clamping block 72 and transmission unit 8 to move towards the stamping station. Simultaneously, the sliding column 852 slides towards the return groove 921, approaching the stamping station. Due to the 5mm distance between the oblique groove 923 and the return groove 921, the sliding column 852 is prevented from accidentally entering the oblique groove 923 during its sliding towards the stamping station. As the sliding column 852 slides to the end of the return groove 921 near the stamping station, it rises... The sliding block 851 remains separated from the conductive plate, the electrochemical fluid is de-energized, the clamping block 71 is released, and the lifting slider 851 remains in its upper position without moving the clamping block 71 until the sliding column 852 slides to the end of the return groove 921 away from the stamping station. All components return to their initial state, the lifting slider 851 resumes linkage and completes the reset, and the end of the guide block 924 away from the stamping station is tilted so that the sliding column 852 can return to the end of the return groove 921 near the stamping station via the guide block 924.

[0036] Example 4: In this embodiment, in addition to the structural features of the aforementioned embodiments, the reciprocating drive assembly 6 includes a mounting cavity 61, a bearing slide plate 62, a rotating column 63, a cone block 64, a lifting component 65, a driving component 66, and a transmission slide plate 67. The mounting cavity 61 is located at the bottom of the operating table 1. The bearing slide plate 62 is slidably mounted on the top surface of the operating table 1 to support the adaptive clamp. The transmission slide plate 67 is slidably mounted in the mounting cavity 61. The rotating column 63 is rotatably mounted on the operating table 1 and extends into the mounting cavity 61 and is connected to the bearing slide plate 62 and the transmission slide plate 67 via a pair of sliding pairs 68. The cone block 64 is rotatably mounted in the mounting cavity 61 via the driving component 66 and has a vertical surface on one side for driving the transmission slide plate 67 to slide horizontally back and forth. The lifting component 65 is used to control the lifting and lowering of the cone block 64.

[0037] In this embodiment of the application, the lifting component 65 includes a lifting shell 651, a lifting bracket 652, and an adjusting bolt 653. The lifting shell 651 is fixed to one side of the operating table 1 and communicates with the mounting cavity 61. The lifting bracket 652 is slidably installed in the mounting cavity 61. The cone block 64 is rotatably installed at the inner end of the lifting bracket 652. The adjusting bolt 653 is rotatably installed in the lifting shell 651 and is connected to the outer end of the lifting bracket 652 through a screw hole.

[0038] In this embodiment of the application, the lifting member 65 further includes a guide groove 654 and a guide post 655. The guide groove 654 vertically penetrates the lifting bracket 652. The guide post 655 is slidably installed in the guide groove 654 and its upper end is fixedly connected to the top of the mounting cavity 61, and its lower end is connected to the bottom of the side wall of the mounting cavity 61 through a base plate.

[0039] In this embodiment of the application, the driving member 66 includes a motor 661 and a polygonal drive shaft 662. The motor 661 is mounted at the bottom of the mounting cavity 61, and the polygonal drive shaft 662 is mounted on the output shaft of the motor 661 and slides through the cone block 64 along the central axis of the cone block 64.

[0040] In this embodiment of the application, the sliding pair 68 includes a transmission groove 681 and a transmission slider 682. The transmission groove 681 extends radially along the rotating column 63, and the transmission slider 682 slides in cooperation with the transmission groove 681.

[0041] like Figures 5 to 9As shown, due to the above structure, when moving the sheet metal, the drive unit 66 motor 661 is started, which drives the cone block 64 to rotate through the polygonal transmission shaft 662. The lifting unit 65 locks the cone block 64 to rotate smoothly. The cone surface of the cone block 64 periodically pushes against the transmission slide plate 67. Under the action of the pushing force and the restoring force of the spring 85, the transmission slide plate 67 slides back and forth, driving the rotating column 63 to deflect, which in turn drives the bearing slide plate 62 to slide back and forth. When the bearing slide plate 62 drives the adaptive fixture away from the stamping station, the sheet metal is clamped. Then, it moves in the opposite direction to send the fixture and sheet metal to the stamping station. The sliding pair 68 structure is used to achieve precise feeding and complete the sheet metal moving process.

[0042] During reset, after the sheet material is fed and the clamp is released, the motor 661 continues to run, driving the cone block 64 to rotate. The cone surface of the cone block 64 separates from the transmission slide plate 67. The transmission slide plate 67 resets under the action of the spring 85 and drives the rotating column 63 to deflect in the opposite direction, thereby driving the bearing slide plate 62 to move away from the stamping station. This drives the adaptive clamp to reset synchronously and remain in the released state until the transmission slide plate 67, rotating column 63, bearing slide plate 62 and all components return to their initial positions. The cone block 64 remains powered and ready, completing the reset process.

[0043] The transmission groove 681 corresponding to the transmission slide plate 67 is shorter in length, and the distance between its corresponding transmission slider 682 and the axis of the rotating column 63 is smaller. On the other hand, the transmission groove 681 corresponding to the bearing slide plate 62 is longer in length, and the distance between its corresponding transmission slider 682 and the axis of the rotating column 63 is larger. Based on this structural design, the reciprocating stroke of the bearing slide plate 62 is greater than that of the transmission slide plate 67, which plays a role in amplifying the stroke.

[0044] In addition, the operator can drive the lifting bracket 652 and the cone block 64 to move up and down by rotating the adjusting bolt 653, thereby changing the diameter of the contact position between the cone block 64 and the transmission slide plate 67, and thus adjusting the stroke of the transmission slide plate 67 each time it is pushed, so as to achieve flexible adjustment of the feeding length each time and adapt to the stamping processing needs of different specifications of automotive shock absorbers.
