Description

Technical Field

[0001] This utility model relates to the technical field of automotive seat crossbeam processing equipment, and in particular to an automotive seat crossbeam flanging device. Background Technology

[0002] To achieve lightweight design, the car seat crossbeam is made by bending sheet metal, resulting in a hollow component. Flanged holes need to be cut into the car seat crossbeam for connecting parts to pass through; that is, two coaxially aligned flanged holes need to be machined into the hollow car crossbeam.

[0003] When machining two coaxially aligned holes using a single punch, the excessive length of the punch results in insufficient rigidity, leading to poor stability at the end furthest from the fixed end. During punching and flanging, this unstable end is prone to radial displacement due to the punching force, affecting the coaxiality between the two holes. This coaxiality error prevents subsequent parts from passing smoothly through both holes, hindering assembly. Even if parts manage to pass through both holes simultaneously, they will be subjected to additional shearing forces, reducing their lifespan and posing safety hazards.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a device for flipping holes in automotive seat crossbeams to improve the coaxiality between the processed coaxial holes.

[0006] The technical solution of this utility model is as follows: A flanging device for automotive seat crossbeams processes a first and a second flanging hole coaxially arranged on a workpiece. The device includes a pressure plate, a support block disposed on the same side of the pressure plate, a first slider, and a second slider. The support block supports the workpiece. The first and second sliders slide axially along the first flanging hole. The first slider is located on the same side of the first and second flanging holes, and the second slider is located between the first and second flanging holes. A downward inclined surface is provided on the side of the first slider away from the workpiece. The downward inclined surface slopes towards the workpiece towards the pressure plate. A protruding structure is provided on the side of the pressure plate closest to the workpiece, aligned with the downward inclined surface.

[0007] A further technical solution is to open a second groove on the support block and set the second slider in the second groove.

[0008] A further technical solution involves providing a guide post within the second groove along the sliding direction of the second slider. The guide post is positioned on the side of the second slider away from the first slider. The second slider is fitted onto the guide post. An elastic element is provided on the guide post between the second slider and the support block.

[0009] A further technical solution includes a base. The support block, the first slider, and the second slider are all mounted on the base. A guide block is also mounted on the base. The end of the guide block furthest from the base is bent, forming a first groove between the guide block and the base. The first slider engages with the first groove.

[0010] A further technical solution involves a first slider positioned on the side of the first flip hole away from the second flip hole. A first punch is positioned on the first slider facing the first flip hole. The outline of the first punch is set perpendicular to the sliding direction of the first slider, corresponding to the outline of the first flip hole.

[0011] A further technical solution involves setting a second punch towards the second flip hole on the second slider. The outline of the second punch is set perpendicular to the sliding direction of the second slider, corresponding to the outline of the second flip hole.

[0012] A further technical solution involves setting a cutting tool on the pressure plate facing downwards. The end of the cutting tool near the first slider has an upper inclined surface parallel to the downward inclined surface.

[0013] A further technical solution involves creating a limiting groove on the inserter parallel to the lower inclined surface. The sidewall of the long side of the limiting groove is set parallel to the lower inclined surface. A limiting hook is provided on the first slider. The limiting hook is located away from the end of the first slider and is bent to extend into the limiting groove.

[0014] A further technical solution involves placing pressure blocks on the surface of the pressure plate close to the workpiece. When the first and second sliders form the first and second flip holes, the pressure blocks, in conjunction with the support blocks, clamp the workpiece.

[0015] A further technical solution involves providing a stop on the surface of the pressure plate near the workpiece. When the first and second sliders form the first and second flanged holes, the stop abuts against the surface of the workpiece away from the first slider. A clearance groove is formed on the stop along the sliding path of the second slider.

[0016] The beneficial technical effects of this utility model are as follows: (1) The car seat crossbeam flanging device of this utility model is provided with a first slider and a second slider to complete the processing of the first and second flanging holes. Compared with using a single structure to process two flanging holes, the separate first slider and the second slider avoid the problem that the length of the processing end of the first slider is too long and the rigidity is insufficient, which affects the stability of the end of the processing end. The separate first slider and the second slider are respectively set close to the flanging holes they are processing. The length of the processing end on the first slider and the second slider is controllable, which improves the stability of the processing end on the first slider and the second slider, thereby improving the coaxiality between the two flanging holes and ensuring the processing accuracy of the workpiece. Moreover, the second slider is pushed by the first slider. The horizontal slider of the first slider can be converted into the vertical movement of the pressure block through the lower inclined surface, which facilitates the processing of the workpiece by the vertically set telescopic device.

[0017] (2) Furthermore, an elastic element is also provided between the second slider and the support block. When the pressure block moves downward to push the second slider for processing, the elastic element is compressed and stores energy. When the pressure block moves upward after processing is completed, the elastic element returns to its original state and releases energy, realizing the automatic reset of the second slider and improving processing efficiency.

[0018] (3) Further, a limiting hook and a limiting groove are provided between the first slider and the insert. When the workpiece is processed and the pressure block moves upward away from the workpiece, the limiting hook and the limiting groove slide relative to each other. The limiting groove provides the limiting hook with a component force in the direction away from the workpiece to drive the first slider away from the workpiece, thereby realizing the automatic reset of the first slider and improving processing efficiency.

[0027] Figure 1 The diagram shows an assembly structure of the base, the first slider, and the second slider in an automotive seat crossbeam flipping device according to an embodiment of the present disclosure. Figure 2 A cross-sectional view at point A is shown of an embodiment of the automotive seat crossbeam flipping device of this disclosure. Figure 3 A partially enlarged view of point B is shown of an automotive seat crossbeam perforation device according to an embodiment of the present disclosure. Figure 4 A three-dimensional structural diagram of the pressure plate in an automotive seat crossbeam flipping device according to an embodiment of this disclosure is shown. Please refer to... Figure 1 , Figure 2 , Figure 3 and Figure 4This is a car seat crossbeam flanging device that processes a first flanging hole 51 and a second flanging hole 52 coaxially arranged on a workpiece 5. The device includes a pressure plate 4, a support block 11 located on the same side of the pressure plate 4, a first slider 2, and a second slider 3. The support block 11 supports the workpiece 5. The first slider 2 and the second slider 3 slide along the axial direction of the first flanging hole 51. The first slider 2 is located on the same side of the first flanging hole 51 and the second flanging hole 52, and the second slider 3 is located between the first flanging hole 51 and the second flanging hole 52. The first flanging hole 51 and the second flanging hole 52 are processed by the stamping action of the first slider 2 and the second slider 3. Compared to processing two flanging holes using a single structure, the separate arrangement of the first slider 2 and the second slider 3 avoids the first slider 2's processing end being too long and lacking rigidity, thus affecting the stability of the processing end. The split-type first slider 2 and second slider 3 are respectively positioned close to their respective machined flip holes. The length of the machined ends on the first slider 2 and second slider 3 is controllable, improving the stability of the machined ends on the first slider 2 and second slider 3, thereby improving the coaxiality between the two flip holes and ensuring the machining accuracy of the workpiece 5. A lower inclined surface 22 is provided on the side of the first slider 2 away from the workpiece 5. The lower inclined surface 22 is inclined towards the workpiece 5 in the direction close to the pressure plate 4. A protruding structure is provided on the side of the pressure plate 4 close to the workpiece 5, aligned with the lower inclined surface 22. When the pressure block 41 moves downward, the protruding structure slides along the lower inclined surface 22, pushing the first slider 2 to slide, while the first slider 2 pushes the second slider 3 to slide. The lateral sliding of the first slider 2 and second slider 3 is converted into the vertical movement of the pressure block 41, which facilitates the machining of the workpiece 5 through a vertically set telescopic device (not shown in the figure).

[0028] Please refer to Figure 1 , Figure 2 and Figure 3 A second sliding groove 111 is formed on the support block 11, and the second slider 3 is disposed in the second sliding groove 111. The second slider 3 and the second sliding groove 111 are fitted with a clearance. In addition to allowing the second slider 3 to slide, the second sliding groove 111 can also avoid the flange of the first flip hole 51 (not shown in the figure), thus avoiding interference between the support block 11 and the first flip hole 51.

[0029] Preferably, a guide post 112 is provided in the second slide groove 111 along the sliding direction of the second slider 3. The guide post 112 is located on the side of the second slider 3 away from the first slider 2. The second slider 3 is sleeved on the guide post 112. An elastic element 113 is provided on the guide post 112 between the second slider 3 and the support block 11. The elastic element 113 can be a spring. When the pressure block 41 moves downward to push the second slider 3 for processing, the elastic element 113 is compressed and stores energy by the second slider 3 and the support block 11. When the pressure block 41 moves upward after processing is completed, the elastic element 113 returns to its original state and releases energy to push the second slider 3, realizing the automatic reset of the second slider and improving processing efficiency.

[0030] Please refer to Figure 1, Figure 2 and Figure 3 The system also includes a base 1. Support block 11, first slider 2, and second slider 3 are all mounted on the base 1. This facilitates a unified positioning reference. Furthermore, after all components are installed, they can move as a whole with the base 1, avoiding the need to reposition the components on the base 1 when adjusting the seat beam side forming device. A guide block 12 is also provided on the base 1. The end of the guide block 12 away from the base 1 is bent, forming a first groove between the guide block 12 and the base 1. The first slider 2 engages with the first groove. Specifically, the two guide blocks 12 cooperate to form a T-shaped first groove on the base 1. An extension 23 can be provided on the first slider 2 to align the lower contour of the first slider 2 with the contour of the first groove. The first groove and the first slider 2 are fitted with a clearance to slidably connect the first slider 2 and the base 1. The first groove also serves as a guide, improving the stability of the first slider 2 during sliding.

[0031] Preferably, the first slider 2 is disposed on the side of the first flip hole 51 away from the second flip hole 52. A first punch 21 is disposed on the first slider 2 facing the first flip hole 51. The outline of the first punch 21 is set perpendicular to the sliding direction of the first slider 2, corresponding to the outline of the first flip hole 51. The sliding of the first slider 2 drives the first punch to stamp and form the first flip hole 51.

[0032] More preferably, the second punch 31 is positioned facing the second flip hole 52 from the second slider 3. The outline of the second punch 31 is set perpendicular to the sliding direction of the second slider 3, corresponding to the outline of the second flip hole 52. The sliding of the second slider 3 drives the second punch to stamp and form the second flip hole 52.

[0033] In some embodiments, multiple first punches 21 and second punches 31 may be provided to simultaneously process multiple sets of first flanged holes 51 and second flanged holes 52 on the workpiece 5.

[0034] Figure 5 This diagram illustrates the assembly structure of the insert and the first slider in an automotive seat crossbeam perforation device according to an embodiment of this disclosure. Please refer to... Figure 2 , Figure 4 and Figure 5 A blade 43 is positioned on the pressure plate 4 facing the lower inclined surface 22. An upper inclined surface 431, parallel to the lower inclined surface 22, is positioned near the end of the blade 43 close to the first slider 2. The upper inclined surface 431 increases the contact area between the blade 43 and the first slider 2, improving the stability of the first slider 2's movement when the blade 43 pushes the first slider.

[0035] Preferably, a limiting groove 432 is formed on the insert 43 parallel to the lower inclined surface 22. The sidewall of the long side of the limiting groove 432 is set parallel to the lower inclined surface 22. A limiting hook 24 is provided on the first slider 2. The limiting hook 24 is bent and extends into the limiting groove 432 away from the end of the first slider 2. After the workpiece 5 is processed, when the pressure block 41 moves upward away from the workpiece 5, the limiting hook 24 and the limiting groove 432 slide relative to each other. The limiting groove 432 provides a component force to the limiting hook 24 in the direction away from the workpiece 5 to drive the first slider 2 away from the workpiece 5, realize the automatic reset of the first slider 2, and improve processing efficiency.

[0036] Please refer to Figure 2 , Figure 3 and Figure 4 A pressure block 41 is provided on the surface of the pressure plate 4 near the workpiece 5. When the first slider 2 and the second slider 3 form the first flip hole 51 and the second flip hole 52, the pressure block 41 cooperates with the support block 11 to clamp the workpiece 5.

[0037] Preferably, a stop 42 is also provided on the surface of the pressure plate 4 near the workpiece 5. When the first slider 2 and the second slider 3 form the first flange 51 and the second flange 52, the stop 42 abuts against the surface of the workpiece 5 away from the first slider 2. Along the sliding path of the second slider 3, a clearance groove (not shown in the figure) is formed on the stop 42. The clearance groove avoids interference between the stop 42 and the second slider 3, and also avoids interference between the stop 42 and the flange of the second flange 52, ensuring that the second flange 52 is correctly processed. The stop 42 abuts against the workpiece 5 to prevent the workpiece 5 from deforming when the second slider 3 punches the second flange 52.

[0038] In some embodiments, the pressure plate 4 and the pressure block 41, as well as the pressure plate 4 and the baffle, can be connected by an elastic structure (not shown in the figure). The elastic structure can be a telescopic cylinder with a built-in spring. After the pressure plate 4 and the baffle 42 contact the fixed workpiece 5, the pressure plate 4 can continue to press down to push the first slider 2 and the second slider 3.

[0039] The specific workflow of this utility model is as follows: When processing workpiece 5, workpiece 5 is placed on support block 11. The telescopic mechanism is activated, driving pressure plate 4 downward. During the downward movement of pressure plate 4, upper inclined surface 431 contacts lower inclined surface 22, and limit hook 24 engages in limit groove 432. The downward movement of upper inclined surface 431 pushes first slider 2, and limit hook 24 extends into limit groove 432. Pressure plate 4 and stop block 42 respectively contact workpiece 5, fixing workpiece 5 on support block 11. Pressure block 41 continues to move downward, and first punch 21 on first slider 2 moves synchronously to punch workpiece 5 to process first flange 51. Then first punch 21 pushes second slider 3, and second punch 31 on second slider 3 moves synchronously to punch workpiece 5 to process second flange 52. At the same time, second slider 3 and support block 11 clamp and compress elastic element 113. Then, the telescopic structure drives the pressure plate 4 to move upward. At this time, the limiting groove 432 and the limiting hook 24 move relative to each other. The limiting groove 432 provides a force to the first slider 2 away from the workpiece 5 through the limiting hook 24, and the first slider 2 resets. The elastic element 113 extends and pushes the second slider 3, and the second slider 3 resets. The machining of the two coaxial flip holes of the workpiece 5 is completed.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
