Description

Technical Field

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

[0002] When the outer edge of the seat side panel is straight, the sharp edge can easily scratch the user, posing a safety hazard. Rounding the outer edge inwards can significantly reduce the sharpness of the outer edge, thereby improving the safety of the seat.

[0003] To conform to ergonomics, the side panels need to be rolled into a rounded shape along their outer edges, while the panels themselves also require a certain degree of curvature. However, the curvature of the side panels themselves differs from that of the rolled-in area, resulting in different springback values, making it difficult to process them in a single step. Splitting the processing of the seat side panels into two steps significantly reduces processing efficiency and increases costs.

[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 side panel rolling device to improve the forming efficiency of seat side panels.

[0006] The technical solution of this utility model is as follows: The seat side panel rolling device includes a first slider, a second slider, a support block, and a pressure block. The first slider, the second slider, and the support block are disposed on the same side of the pressure block. The first slider and the second slider are slidably disposed towards each other. An arc groove is formed on the surface of the support block near the pressure block. A first inclined surface is raised on the surface of the pressure block near the first slider. An acute angle is formed between the first inclined surface and the sliding direction of the first slider. The first inclined surface faces the second slider. Perpendicular to the sliding direction of the first slider, the first inclined surface is aligned with the outer edge of the first slider away from the second slider.

[0007] A further technical solution involves a second inclined surface protruding from the surface of the pressure block near the second slider. The second inclined surface forms an acute angle with the sliding direction of the second slider. The second inclined surface faces the first slider. Perpendicular to the sliding direction of the second slider, the second inclined surface is aligned with the outer edge of the second slider away from the first slider.

[0008] A further technical solution involves providing a first insert and a second insert on the pressure block. A first inclined surface is provided on the first insert. A second inclined surface is provided on the second insert.

[0009] A further technical solution is to provide at least two first inserters and two second inserters.

[0010] A further technical solution involves providing an elastic element between the first and second sliders. The extension / retraction direction of the elastic element is set along the sliding direction of the first and second sliders.

[0011] A further technical solution involves providing a base plate, on which the first and second sliders are slidably mounted. A support block is also mounted on the base plate.

[0012] A further technical solution involves setting a first positioning rod on the base plate. A second positioning rod is positioned on the pressure block, aligned with the first positioning rod. The first and second positioning rods are positioned facing each other.

[0013] A further technical solution involves setting a guide rod on the pressure block facing the base plate. A guide sleeve is designed on the base plate for the guide rod to extend into.

[0014] A further technical solution is to also provide a slide rail, with grooves on the first and second sliders for the slide rail to engage.

[0015] A further technical solution involves setting a limiting rod on the slide rail. A limiting groove is formed on the first slider along the sliding direction of the first slider to allow the limiting rod to extend into it.

[0016] The beneficial technical effects of this utility model are as follows: (1) The seat side panel rolling device of this utility model is provided with a first slider and a second slider. The workpiece can be inserted between the first slider and the second slider and clamped to quickly form the curvature of the workpiece. A support block and a pressure block are also provided. An arc groove is opened on the support block. The outer edge of the bent workpiece can be inserted into the arc groove. Then the pressure block squeezes the side panel, so that the outer edge of the workpiece bends and deforms along the inner wall of the arc groove and is rolled. The pressure block is provided with a first inclined surface to cooperate with the first slider. While the pressure block is pressing the workpiece downward to roll it, the pressure block pushes the first slider through the first inclined surface. At this time, the moving first slider can cooperate with the second slider to clamp and bend another workpiece, completing two forming processes at the same time, which significantly improves the efficiency of workpiece processing and reduces the processing cost of workpiece.

[0017] (2) Furthermore, a second inclined surface is provided on the pressure plate. The first and second inclined surfaces work together to drive the first and second sliders to move towards each other to clamp the workpiece. The first and second sliders slide and squeeze the workpiece towards each other, and the opposite side of the workpiece is subjected to symmetrical pressure, so that the force on the workpiece is more uniform, thereby improving the accuracy of workpiece forming.

[0018] (3) Further, an elastic element is provided between the first slider and the second slider. When the pressure block moves downward, driving the first slider and the second slider closer to clamp the workpiece, the elastic element is compressed. After the pressure block moves upward and away from the first slider and the second slider, the elastic element returns to its original state and pushes the first slider and the second slider, thereby realizing the automatic reset of the first slider and the second slider.

[0025] Figure 1 The diagram shows an assembly structure of the base plate, the first slider, the second slider, and the support block in a seat side panel rolling device according to an embodiment of the present disclosure. Figure 2A three-dimensional structural schematic diagram of the pressure block in a seat side panel rolling device according to an embodiment of this disclosure is shown. Please refer to... Figure 1 and Figure 2 The seat side panel rolling device includes a first slider 2, a second slider 3, a support block 4, and a pressure block 5. The first slider 2, the second slider 3, and the support block 4 are disposed on the same side of the pressure block 5. The first slider 2 and the second slider 3 are slidably disposed towards each other, and the workpiece can be inserted between the first slider 2 and the second slider 3 and clamped to quickly form the curvature of the workpiece. In some embodiments, the workpiece can be a seat side panel. An arcuate groove 41 is formed on the surface of the support block 4 near the pressure block 5. The outer edge of the bent workpiece can extend into the arcuate groove 41, and then the pressure block 5 presses the side panel, causing the outer edge of the workpiece to bend and deform along the inner wall of the arcuate groove 41 and be rolled into a circle. A first inclined surface 511 is raised on the surface of the pressure block 5 near the first slider 2. The first inclined surface 511 forms an acute angle with the sliding direction of the first slider 2. The first inclined surface 511 is disposed facing the second slider 3. Perpendicular to the sliding direction of the first slider 2, the first inclined surface 511 is disposed aligned with the outer edge of the first slider 2 away from the second slider 3. As the pressure block 5 descends and extrudes the workpiece to roll it into a circle, it simultaneously pushes the first slider 2 via the first inclined surface 511. At this time, the moving first slider 2, in conjunction with the second slider 3, clamps and bends another workpiece, completing two forming processes at the same time. This significantly improves the efficiency of workpiece processing and reduces processing costs. While forming the workpiece, the pressure block 5 contacts the first slider 2, the second slider 3, and the support block 4 to clamp the workpiece, preventing displacement during forming and improving stability.

[0026] Please refer to Figure 1 and Figure 2 A second inclined surface 521 is raised on the surface of the pressure block 5 near the second slider 3. The second inclined surface 521 forms an acute angle with the sliding direction of the second slider 3. The second inclined surface 521 faces the first slider 2. Perpendicular to the sliding direction of the second slider 3, the second inclined surface 521 is aligned with the outer edge of the second slider 3 away from the first slider 2. While the pressure block 5 descends to compress the workpiece and roll it into a circle, it pushes the second slider 3 through the second inclined surface 521. At this time, the moving second slider 3 can cooperate with the first slider 2 to clamp and bend another workpiece, completing two forming processes simultaneously, significantly improving the efficiency of workpiece processing and reducing processing costs. Furthermore, the first inclined surface 511 and the second inclined surface 521 work together to drive the first slider 2 and the second slider 3 to move towards each other to clamp and form the workpiece. The first slider 2 and the second slider 3 slide and compress the workpiece towards each other, resulting in symmetrical pressure on opposite sides of the workpiece, making the force on the workpiece more uniform and improving the forming accuracy.

[0027] Preferably, the pressure block 5 is provided with a first insert 51 and a second insert 52. A first inclined surface 511 is provided on the first insert 51. A second inclined surface 521 is provided on the second insert 52. At least two first inserts 51 and two inserts 52 are provided respectively, so as to apply the pushing force more evenly on the first slider 2 and the second slider 3, thereby improving the stability of the movement of the first slider 2 and the second slider 3.

[0028] Figure 3 An exploded view of the structure between the first slider, the second slider, and the slide rail in a seat side panel rolling device according to an embodiment of this disclosure is shown. Please refer to... Figure 1 and Figure 3 An elastic element (not shown in the figure) is provided between the first slider 2 and the second slider 3. The elastic element can be a spring. The extension and retraction direction of the elastic element is set along the sliding direction of the first slider 2 and the second slider 3. Specifically, the second slider 3 is provided with a reset rod 31 facing the first slider 2. A hole (not shown in the figure) is opened on the first slider 2 for the reset tube to extend into, and the elastic element is sleeved on the reset rod 31. When the pressure block 5 moves downward to drive the first slider 2 and the second slider 3 closer to clamp the workpiece, the elastic element is compressed. After the pressure block 5 moves upward away from the first slider 2 and the second slider 3, the elastic element returns to its original state and pushes the first slider 2 and the second slider 3, realizing the automatic reset of the first slider 2 and the second slider 3.

[0029] Preferably, a slide rail 13 is also provided, and the first slider 2 and the second slider 3 are respectively provided with a groove 21 for the slide rail 13 to engage. The groove 21 and the slide rail 13 are in clearance fit. In some embodiments, the slide rail 13 can be a T-shaped slide rail 13, and the groove 21 is a T-shaped slot for the slide rail 13 to engage. This further restricts the degrees of freedom of the first slider 2 and the second slider 3, improving the stability of the first slider 2 and the second slider 3 during sliding.

[0030] More preferably, a limiting rod 14 is provided on the slide rail 13. A limiting groove 22 is formed on the first slider 2 along its sliding direction for the limiting rod 14 to extend into. The limiting rod 14 cooperates with the limiting groove 22 to restrict the sliding stroke of the first slider 2 and prevent it from falling off the slide rail 13. Simultaneously, a hole can be formed on the pressure block 5 to cooperate with the limiting rod 14, further positioning the pressure block 5 and the slider. In some embodiments, limiting blocks 131 are provided at both ends of the slide rail 13 to prevent the first slider 2 and the second slider 3 from falling off the slide rail 13.

[0031] Please refer to Figure 1 , Figure 2 and Figure 3It also includes a base plate 1, with a slide rail 13 mounted on the base plate 1. The first slider 2 and the second slider 3 are slidably mounted on the base plate 1 via the slide rail 13. The support block 4 is also mounted on the base plate 1. All components are centrally mounted on the base plate 1, providing a unified positioning reference. After installation, each component can move as a whole with the base plate 1, avoiding repeated clamping and adjustment of the positions between components.

[0032] Preferably, a first positioning rod 11 is provided on the base plate 1. A second positioning rod 53 is provided on the pressure block 5, aligned with the first positioning rod 11. The first positioning rod 11 and the second positioning rod 53 are arranged facing each other. This limits the distance between the base plate 1 and the pressure block 5, preventing excessive pressure between the base plate 1 and the pressure block 5 from damaging the components.

[0033] More preferably, a guide rod 54 is provided on the pressure block 5 facing the base plate 1. A guide sleeve 12 is designed on the base plate 1 for the guide rod 54 to extend into. The guide rod 54 and the guide sleeve 12 cooperate to limit the relative position between the pressure block 5 and the base plate 1.

[0034] The specific workflow of this utility model is as follows: When forming a workpiece, the workpiece requiring an arc is placed on the first slider 2, with its side plate extending between the first slider 2 and the second slider 3. The workpiece requiring a rolled shape is placed on the support block 4. Then, the pressure block 5 is driven downwards towards the base plate 1 via a telescopic mechanism (not shown in the figure). During this process, the first inclined surface 511 contacts and pushes the first slider 2 towards the second slider 3, and the second inclined surface 521 contacts and moves the second slider 3 towards the first slider 2. The first slider 2 and the second slider 3 clamp and form the arc of the workpiece's side plate, compressing the elastic element between the first slider 2 and the second slider 3. Simultaneously, the pressure block 5 moves downwards and the support block 4 clamps and squeezes the workpiece. The outer edge of the workpiece's side plate slides and bends along the inner wall of the arc groove 41, becoming rolled. Finally, the telescopic mechanism lifts the pressure block 5 away from the base plate 1. At this time, the elastic element extends and returns to its original position, pushing the first slider 2 and the second slider 3 back to their original positions. Both workpieces can be removed, and subsequent workpieces requiring an arc can be placed at the support block 4 for rolling.

[0035] 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.

[0036] 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.
