Description

Technical Field

[0001] This utility model relates to the field of molding equipment technology, and in particular to a seat crossbeam side molding device. Background Technology

[0002] The ends of the car seat crossbeam are bent to increase the contact area between the crossbeam and the seat side panel, slide rail, frame or other components, thereby enhancing the stability of the crossbeam connection.

[0003] When machining the bent portion of the seat crossbeam, the crossbeam must first be clamped and fixed, and then the bent portion must be bent. This process is rather cumbersome and has low production efficiency. Inadequate clamping and fixing can also affect the bending quality, further impacting the production efficiency of the seat crossbeam.

[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 seat crossbeam side forming device to improve the production efficiency of seat crossbeam workpieces.

[0006] The technical solution of this utility model is as follows: The seat crossbeam side forming device includes a pressure block, a lower fixed block disposed on the same side of the pressure block, a clamping slider, and a bending slider. A workpiece is disposed on the lower fixed block. The clamping slider is slidably disposed toward the workpiece. The bending slider is slidably disposed toward the bent portion of the workpiece and along the bending direction of the bent portion. A first inclined surface is disposed on the side of the clamping slider away from the workpiece, and a second inclined surface is disposed on the side of the bending slider away from the workpiece. The first and second inclined surfaces gradually approach the workpiece towards the pressure block. A raised structure is provided on the surface of the pressure block to contact the first and second inclined surfaces.

[0007] A further technical solution involves a raised bump on the surface of the bending slider facing the bending portion. The side of the bump forms an angle of ≥90° with the bending slider, and a concave fillet is provided for transition. The bending portion is positioned along the side of the bump towards the concave fillet.

[0008] A further technical solution involves providing two retaining edges on the clamping slider and the bending slider respectively, along the sliding direction of the clamping slider and the bending slider. A protruding structure extends between the two retaining edges to contact either the first or second inclined surface.

[0009] A further technical solution is that the protruding structure includes a first insert and a second insert. The first insert contacts a first inclined surface, and the second insert contacts a second inclined surface.

[0010] A further technical solution involves creating a limiting groove on the surface of the first insert blade perpendicular to the sliding direction of the clamping slider. A limiting hook is provided on the clamping slider. The limiting groove is parallel to the first inclined surface. The end of the limiting hook away from the clamping slider extends into the limiting groove.

[0011] A further technical solution involves creating a limiting groove on the surface of the second insert perpendicular to the sliding direction of the bending slider. A limiting hook is provided on the bending slider. The limiting groove is parallel to the second inclined surface. The end of the limiting hook away from the bending slider extends into the limiting groove.

[0012] A further technical solution includes a base. The lower fixing block, clamping slider, and bending slider are centrally mounted on the base.

[0013] A further technical solution involves installing a pressure plate on the base. A groove is formed between the pressure plate and the base. The clamping slider and the bending slider are engaged in the groove.

[0014] A further technical solution involves providing a guide rod on the pressure block. A guide sleeve is provided on the base for the guide rod to extend into.

[0015] A further technical solution involves aligning the upper fixing block with the lower fixing block. The workpiece is positioned between the upper and lower fixing blocks. The bent portion extends from between the upper and lower fixing blocks.

[0016] The beneficial technical effects of this utility model are as follows: (1) The seat beam side forming device of this utility model is provided with a lower fixing block for placing the workpiece, a clamping slider for clamping the workpiece in cooperation with the lower fixing block, and a bending slider for forming the bent part of the workpiece. While the pressure block moves down to clamp and fix the workpiece, the pressure block simultaneously pushes the clamping slider and the bending slider along the first and second inclined surfaces to complete the clamping and bending of the workpiece. Only one downward movement of the pressure block is needed to complete the clamping and bending processes. The bending can be performed without the operator manually clamping the workpiece, which greatly shortens the processing cycle of the workpiece, improves the production efficiency of the workpiece, and reduces the production cost of the workpiece.

[0017] (2) Further, a protrusion is provided on the bending slider, and a concave rounded corner transitions between the protrusion and the bending slider. When bending the workpiece, the bending edge of the workpiece enters the concave rounded corner along the side of the protrusion, and slides and deforms along the concave arc surface of the concave rounded corner to contact the surface of the bending slider, and continues to be squeezed and bent to the predetermined position along the surface of the bending slider, which facilitates forming. The concave rounded corners can be symmetrically provided on the opposite side of the protrusion to process two bending parts on the workpiece that are set opposite to each other at the same time, so as to ensure production efficiency.

[0018] (3) Furthermore, baffles are provided on the clamping slider and the bending slider to position and restrict the sliding path of the first insert and the second insert along the first inclined plane and the second inclined plane, thereby improving the stability of the pressure block when it descends, ensuring that the workpiece is properly clamped and bent, and ensuring the processing quality of the workpiece.

[0027] Figure 1 A three-dimensional structural schematic diagram of a seat beam side forming apparatus according to an embodiment of the present disclosure is shown in a top view. Figure 2 A three-dimensional structural schematic diagram of a seat crossbeam processed in a seat crossbeam side forming apparatus according to an embodiment of this disclosure is shown. Please refer to... Figure 1 and Figure 2 The seat crossbeam side forming device includes a pressure block 4, a lower fixing block 31 disposed on the same side of the pressure block 4, a clamping slider 1, and a bending slider 2. A workpiece 5 is disposed on the lower fixing block 31. The clamping slider 1 slides toward the workpiece 5, cooperating with the lower fixing block 31 to clamp the workpiece 5. The bending slider 2 slides toward the bent portion 51 of the workpiece 5 and along the bending direction of the bent portion 51, pushing the slider of the bent portion 51 to slide, thereby processing the bent portion 51. A first inclined surface 11 is disposed on the side of the clamping slider 1 away from the workpiece 5, and a second inclined surface 21 is disposed on the side of the bending slider 2 away from the workpiece 5. The first inclined surface 11 and the second inclined surface 21 gradually approach the workpiece 5 in the direction closer to the pressure block 4. A raised structure is disposed on the surface of the pressure block 4 to contact the first inclined surface 11 and the second inclined surface 21. While the pressure block 4 descends to clamp and fix the workpiece 5, the pressure block 4 simultaneously pushes the clamping slider 1 and the bending slider 2 along the first inclined surface 11 and the second inclined surface 21, completing the clamping and bending processing of the workpiece 5. The clamping slider 1 first clamps the workpiece 5, and then the bending slider 2 bends the workpiece 5, completing the forming of the workpiece 5. The order of the clamping and bending actions can be adjusted by changing the distance between the workpiece slider, the bending slider 2, and the workpiece 5, or by adjusting the distance between the clamping slider 1, the bending slider 2, and the pressure block 4. Only one downward movement of the pressure block 4 is needed to complete both the clamping and bending processes. Bending can be performed without the operator manually clamping the workpiece 5, significantly shortening the processing cycle of the workpiece 5, improving its production efficiency, and reducing its production cost.

[0028] In some embodiments, two or more clamping sliders 1 can be provided to fix the workpiece 5 at multiple points. Taking two clamping sliders 1 as an example, the two clamping sliders 1 are set on opposite sides of the workpiece 5 to improve the stability of the workpiece 5. Two bending sliders 2 can also be provided. Taking the workpiece 5 as a seat crossbeam as an example, the two ends of the workpiece 5 are respectively provided with bending portions 51, and the two bending sliders 2 can respectively correspond to one end of the length of the workpiece 5 to simultaneously complete the processing of all bending portions 51 on the workpiece 5.

[0029] Figure 3 A schematic diagram of the assembly structure of the first insert and the clamping slider in a seat beam side forming apparatus according to an embodiment of the present disclosure is shown. Figure 4 A three-dimensional structural schematic diagram of a seat beam side forming apparatus according to an embodiment of the present disclosure is shown in the upward view. Figure 5 A schematic diagram of the assembly structure between the bending slider and the second insert blade in a seat beam side forming apparatus according to an embodiment of this disclosure is shown. Please refer to... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The bending slider 2 has a protrusion 22 on its surface facing the bending portion 51. The side of the protrusion 22 forms an angle of ≥90° with the bending slider 2, and a concave fillet 221 is provided for transition. The bending portion 51 is positioned along the side of the protrusion 22 towards the concave fillet 221. When bending the workpiece 5, the bent edge of the workpiece 5 enters the concave fillet 221 along the side of the protrusion 22, and slides and deforms along the concave arc surface of the concave fillet 221, contacting the surface of the bending slider 2. It continues to be pressed and bent to a predetermined position along the surface of the bending slider 2, facilitating forming. The concave fillets 221 can be symmetrically arranged on opposite sides of the protrusion 22 to simultaneously process two opposing bending portions 51 on the workpiece 5, ensuring production efficiency.

[0030] Preferably, along the sliding direction of the clamping slider 1 and the bending slider 2, two retaining edges 12 are respectively provided on the clamping slider 1 and the bending slider 2. The protruding structure extends between the two retaining edges 12 and contacts the first inclined surface 11 or the second inclined surface 21. Taking the protruding structure as the first insert 42 and the second insert 43 as an example, when the first insert 42 contacts the first inclined surface 11 and slides relative to it, the two retaining edges 12 on the clamping slider 1 can restrict the sliding path of the first insert 42 along the first inclined surface 11; when the second insert 43 contacts the second inclined surface 21 and slides relative to it, the two retaining edges 12 on the bending slider 2 can restrict the sliding path of the second insert 43 along the second inclined surface 21, so as to improve the stability of the pressure block 4 when it descends, ensure that the workpiece 5 is correctly clamped and bent, and ensure the processing quality of the workpiece 5.

[0031] More preferably, an upper fixing block 41 is provided on the pressure block 4, aligned with the lower fixing block 31. The workpiece 5 is clamped and fixed between the upper fixing block 41 and the lower fixing block 31. Correspondingly, a cavity (not shown in the figure) corresponding to the shape of the workpiece 5 is formed between the upper fixing block 41 and the lower fixing block 31. The bent portion 51 extends from between the upper fixing block 41 and the lower fixing block 31. When forming the bent portion 51, the surfaces of the upper fixing block 41 and the lower fixing block 31 can abut against and position the bent portion 51, ensuring the processing accuracy of the bent portion 51.

[0032] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The protruding structure includes a first insert 42 and a second insert 43. The first insert 42 contacts the first inclined surface 11, and the second insert 43 contacts the second inclined surface 21. Corresponding to the first inclined surface 11, the first insert 42 can be provided with an inclined surface (not marked in the figure) that contacts the first inclined surface 11, and the inclined surface is set parallel to the first inclined surface 11; corresponding to the second inclined surface 21, the second insert 43 can be provided with an inclined surface that contacts the second inclined surface 21, and the inclined surface is set parallel to the second inclined surface 21, so as to increase the contact area between the first insert 42 and the first inclined surface 11, and increase the contact area between the second insert 43 and the second inclined surface 21, thereby enhancing the stability of the pressure block 4 when it descends.

[0033] Preferably, a limiting groove 421 extends from the first insert 42. A limiting hook 14 is provided on the clamping slider 1, with one end of the limiting hook 14 away from the clamping slider 1 engaging in the limiting groove 421. The limiting groove 421 is parallel to the first inclined surface 11. A limiting groove 421 also extends from the second insert 43. Another limiting hook 14 is provided on the bending slider 2 and engages in the limiting groove 421. When the pressure block 4 moves downwards and approaches the workpiece 5, the first insert 42 / second insert 43 approaches the clamping slider 1 / bending slider 2. At this time, the limiting hook 14 engages in the limiting groove 421 and slides relative to the limiting groove 421. The sliding between the limiting hook 14 and the limiting groove 421 guides the movement of the first insert 42 and the second insert 43, improving the stability of the movement of the first insert 42 and the second insert 43. When the subsequent pressing block 4 moves upward away from the workpiece 5, the inclined inner wall of the limiting groove 421 pushes the limiting hook 14, providing force to the clamping slider 1 and the bending slider 2 away from the workpiece 5, so as to drive the clamping slider 1 and the bending slider 2 to slide away from the workpiece 5 and automatically reset.

[0034] Please refer to Figure 1 and Figure 3 It also includes a base 3. The lower fixing block 31, clamping slider 1, and bending slider 2 are centrally located on the base 3, providing a unified positioning reference. Furthermore, after all components are installed, they can move as a whole with the base 3, avoiding the need to reposition the components on the base 3 when adjusting the seat beam side forming device.

[0035] Preferably, a pressure plate 32 is provided on the base 3. A groove 321 is formed between the pressure plate 32 and the base 3. The clamping slider 1 and the bending slider 2 are engaged in the groove 321. In some embodiments, the groove 321 can be a T-shaped groove, and sliding extensions 13 are respectively provided on the clamping slider 1 and the bending slider 2 to form T-shaped ends. These ends are engaged in the T-shaped groove with clearance fit to slidably connect the clamping slider 1 and the bending slider 2 on the base 3. More preferably, the pressure block 4 is also provided with a guide rod 44. The base 3 is provided with a guide sleeve 33 for the guide rod 44 to extend into. When the pressure block 4 moves downward, the guide rod 44 slides along the guide sleeve 33 to guide the pressure block 4 to move, ensuring that the pressure block 4 is aligned with the base 3 to achieve the expected molding effect.

[0036] The specific workflow of this utility model is as follows: When forming workpiece 5, workpiece 5 is placed on the lower fixed block 31. The driving pressure block 4 moves downwards towards workpiece 5, and the downward pressure block 4 drives the first insert 42 and the second insert 43 to move downwards synchronously. During this process, the first insert 42 contacts the first inclined surface 11 and continues to move downwards. The first insert 42 and the first inclined surface 11 slide relative to each other. The first insert 42 pushes the clamping slider 1 closer to workpiece 5 until the clamping slider 1 cooperates with the lower fixed block 31 to clamp workpiece 5. At the same time, the second insert 43 contacts the second inclined surface 21 and continues to move downwards. The second insert 43 and the second inclined surface 21 slide relative to each other. The second insert 43 pushes the bending slider 2 closer to workpiece 5. During the process of the second insert 43 approaching workpiece 5, the bent part 51 slides along the side of the protrusion 22 into the concave rounded corner 221, and slides and deforms along the concave arc surface of the concave rounded corner 221 until it contacts the surface of the bending slider 2. Then the bent part 51 continues to be squeezed and bent along the surface of the bending slider 2 until the bent part 51 is clamped by the upper fixed block 41 and the bending slider 2. Then the pressure block 4 moves upward, the limiting groove 421 and the limiting hook 14 slide relative to each other, the limiting groove 421 provides the limiting hook 14 with a component force away from the workpiece 5, driving the clamping slider 1 and the bending slider 2 to reset, at which point the workpiece 5 can be taken out, and the workpiece 5 is formed.

[0037] 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.

[0038] 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.
