[0015] Compared with the prior art, the present invention provides a stamping die for an automotive seat frame, which has the following advantages:
[0016] 1. This automotive seat frame stamping die, equipped with a clamping mechanism, along with a sliding groove and a slidable moving block on the base, allows the entire clamping box to flexibly adjust its position to accommodate frames of different sizes. The core clamping action is achieved by rotating a knob to drive a threaded rod, which in turn moves the threaded cylinder connected to it axially, thereby pushing the connecting piece. The connecting piece, through a hinged frame, pushes a baffle, which in turn pushes the moving block to move, thus compressing the groove located at the center of the moving block. This causes the moving block to stretch the second telescopic spring and compress the first telescopic spring, which in turn pushes the fixed plate to apply or release clamping force to the seat frame. The operation is simple and intuitive, the clamping is reliable, and the clamping force can be precisely controlled through the threaded pair, effectively ensuring the stability of the workpiece during the stamping process.
[0017] 2. This automotive seat frame stamping die, through the setting of an auxiliary mechanism, in conjunction with a sliding groove, a sliding block, a hinge block, and a connecting rod, when the baffle is driven to rotate by the clamping mechanism, its inner surface drives the hinge block to move through the connecting rod. The hinge block then drives the sliding block to slide linearly within the sliding groove fixed to the side wall of the clamping box. This design cleverly transforms the rotational motion of the baffle into the linear guiding motion of the sliding block. Its function is similar to a parallelogram stabilizing mechanism. Its core benefit is that it significantly constrains the degree of freedom of the baffle during rotation, preventing unnecessary shaking or deviation, and ensuring that the baffle's movement trajectory is more precise and stable.

[0023] like Figures 1-4 As shown, this utility model provides a technical solution: a stamping die for an automobile seat frame, including a base 1, a support frame 11 fixedly connected to the upper surface of the base 1, a support plate 12 fixedly connected to the upper surface of the support frame 11, and a clamping mechanism 3 provided on the upper surface of the base 1. The clamping mechanism 3 includes: a clamping box 31, a slot 32, a knob 33, a threaded rod 34, a threaded cylinder 35, a connector 36, a hinge frame 37, a baffle 38, a fixed shaft 39, a moving block 310, and a sliding groove 311.
[0024] In one embodiment of this utility model, a sliding groove 311 is formed on the upper surface of the base 1. A movable block 310 is slidably connected to the upper surface of the sliding groove 311. A clamping box 31 is fixedly connected to the upper surface of the movable block 310. A slot 32 is formed inside the clamping box 31. A knob 33 is rotatably connected to the end of the clamping box 31 near the support frame 11. A threaded rod 34 is fixedly connected to the end of the knob 33 away from the support frame 11. The inner surface of the threaded cylinder 35 is threadedly connected to the inner surface of the threaded rod 34. A connector 36 is fixedly connected to the end of the threaded cylinder 35 away from the support frame 11. A hinge frame 37 is hinged to the side wall of the connector 36. A baffle 38 is fixedly connected to the end of the hinge frame 37 away from the connector 36. A fixed shaft 39 is rotatably connected to the inner side wall of the clamping box 31. The outer surface of the fixed shaft 39 is fixedly connected to the lower end of the baffle 38. The lower surface of the movable block 310 is fixedly connected to... A slider matching the size of the slide groove 311 is provided. With the clamping mechanism 3, the slide groove 311 and the slidable moving block 310 are provided on the base 1, so that the entire clamping box 31 can be flexibly adjusted to adapt to the frame of different sizes. The core clamping action is driven by rotating the knob 33 to drive the threaded rod 34 to rotate, which drives the threaded cylinder 35 connected to it to move axially, thereby pushing the connecting piece 36. The connecting piece 36 pushes the baffle 38 through the hinge frame 37, so that the baffle 38 can push the moving block 310 to move, thereby squeezing the groove set in the center of the moving block 310, so that the moving block 310 stretches the second telescopic spring 52 and squeezes the first telescopic spring 51, and then pushes the fixed plate 55 to apply or release the clamping force to the seat frame. The operation is simple and intuitive, the clamping is reliable, and the clamping force can be precisely controlled by the threaded pair, which effectively ensures the stability of the workpiece during the stamping process.
[0025] Additionally, an auxiliary mechanism 4 is provided on the side wall of the clamping box 31. The auxiliary mechanism 4 includes a sliding groove 41, one end of which is fixedly connected to the inner side wall of the clamping box 31. A sliding block 42 is slidably connected to the side wall of the sliding groove 41. A hinge block 43 is fixedly connected to the side of the sliding block 42 away from the sliding groove 41. A connecting rod 44 is hinged to the outer surface of the hinge block 43. One end of the connecting rod 44 is fixedly connected to the inner surface of the baffle 38. A locking block is fixedly connected to the side of the clamping box 31 near the support frame 11. Multiple sets of auxiliary mechanisms 4 are provided, with each pair of auxiliary mechanisms 4 distributed in a mirror-symmetrical manner on the inner side wall of the clamping box 31. With the cooperation of sliding groove 41, sliding block 42, hinge block 43 and connecting rod 44, when the baffle 38 is driven to rotate by the clamping mechanism 3, its inner surface drives the hinge block 43 to move through the connecting rod 44. The hinge block 43 then drives the sliding block 42 to slide linearly in the sliding groove 41 fixed to the side wall of the clamping box 31. This design cleverly transforms the movement of the baffle 38 into the linear guiding movement of the sliding block 42. Its function is similar to a parallelogram stabilizing mechanism. Its core benefit is that it significantly restricts the degree of freedom of the baffle 38 during rotation, preventing unnecessary shaking or deviation, and ensuring that the movement trajectory of the baffle 38 is more accurate and stable.
[0026] In this embodiment of the utility model, a stamping assembly 2 is provided on the lower surface of the support plate 12. The stamping assembly 2 includes a telescopic cylinder 21. The fixed tube of the telescopic cylinder 21 is fixedly connected to the lower surface of the support plate 12. A connecting plate 22 is fixedly connected to the movable end of the telescopic cylinder 21. A stamping head 23 is detachably connected to the lower surface of the connecting plate 22. The lower surface of the connecting plate 22 is fixedly connected to the upper surface of the clamping box 31. A fixed frame 24 is fixedly connected to one end of the support frame 11 near the telescopic cylinder 21. By providing the telescopic cylinder 21 and the stamping head 23, stamping and drilling of the workpiece can be completed. A telescopic rod 5 is fixedly connected to one end of the fixed frame 24 near the clamping box 31. A telescopic spring 51 is sleeved on the outer surface of the telescopic rod 5. One end of the telescopic spring 51 is close to the fixed frame 24 for telescopic movement. One end of cylinder 21 is fixedly connected, and the other end of telescopic spring 51 is fixedly connected to the end of moving block 310 near support frame 11. The end of moving block 310 away from fixed frame 24 is fixedly connected to one end of movable rod 53. Telescopic spring 52 is sleeved on the outer surface of movable rod 53. The other end of movable rod 53 is fixedly connected to fixed plate 55. Protective sleeve 54 is sleeved on the outer surface of telescopic spring 52. Under the action of clamping mechanism 3, telescopic spring 51 is compressed, and telescopic spring 52 adapts to the shape of the workpiece and works with fixed plate 55 to fix the workpiece. A rubber pad is fixedly connected to the end of fixed plate 55 away from support frame 11. The rubber pad can fully alleviate the hard clamping caused to the workpiece and increase friction to achieve a better clamping effect.
[0027] In this invention, during use, the operator first places the car seat frame blank to be stamped between two sets of fixed plates 55, and then rotates the knob 33 at one end of the clamping box 31. The knob 33 drives the threaded rod 34 fixedly connected to it to rotate. Since the threaded rod 34 is threadedly connected to the inner surface of the threaded cylinder 35, the rotation of the threaded rod 34 drives the threaded cylinder 35 to move along its axis. The movement of the threaded cylinder 35 pushes the hinge frame 37, which is hinged to it, through the connecting piece 36 fixedly connected to its end. The hinge frame 37 drives the baffle 38 fixedly connected to its end to rotate around the fixed shaft 39 on the side wall of the clamping box 31, thereby pushing the moving block 310. During this process, multiple sets of auxiliary mechanisms 4, which are mirror-symmetrically distributed on the inner wall and side wall of the clamping box 31, work together. The connecting rod 44 moves with the baffle 38. The movement pulls or pushes the sliding block 42 to slide within the sliding groove 41, thereby enhancing the stability and clamping force of the baffle 38. After the workpiece is clamped, the telescopic cylinder 21 on the lower surface of the support plate 12 is activated, and its movable end pushes the connecting plate 22 downward. The connecting plate 22 drives the stamping head 23, which is detachably connected to its lower surface, to move downward. The fixed workpiece is stamped and formed. The telescopic rod 5 connected to the fixed frame 24 and its sleeved telescopic spring 51, as well as the movable rod 53 connected to the moving block 310, its sleeved telescopic spring 52, the protective sleeve 54, and the rubber pad on the end fixed plate 55 work together to buffer and absorb the vibration and impact generated by the stamping, ensuring the smoothness of the stamping process and the positioning accuracy of the mold. After the stamping is completed, the baffle 38 can be released and the finished product can be taken out by rotating the knob 33 in the opposite direction.
[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
