Description

Technical Field

[0001] This utility model relates to the field of hole-flipping mold technology, and more specifically, to a high-efficiency hole-flipping mold for automobile seats. Background Technology

[0002] Car seats are an important component of a car's interior, primarily composed of a frame, foam, and upholstery. They provide support and comfort for occupants, offering adjustable features to suit different needs. Some seats also include ventilation and heating functions, and some high-end seats even feature massage functions. While enhancing the riding experience, they also play a crucial role in ensuring driving safety. The car seat frame is generally assembled from multiple metal parts through welding, bolting, and other methods. At these connection points, perforations are often used to provide more reliable connection points.

[0003] In automotive seat machining, the flanging of components is performed on a support member, which is spring-loaded. Pressure is applied to the machining component via the upper flanging structure, causing the support member to descend. This allows the lower flanging head to protrude from the support member and perform flanging at the punching location. However, the small contact area between the support member and the machining component, coupled with concentrated pressure, easily leads to deformation of the machining component, compromising the quality of the automotive seat components. Therefore, we propose a high-efficiency flanging mold for automotive seats. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a high-efficiency flanging mold for automobile seats. This solves the technical problem that the current support plate has a small contact area with the workpiece, and the workpiece is prone to deformation due to pressure concentration when the workpiece applies pressure to the support plate, which is not conducive to ensuring the quality of automobile seat components.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-efficiency flanging mold for automobile seats, including a lower flanging mechanism and an upper flanging mechanism and a support mechanism disposed on the lower flanging mechanism. The lower flanging mechanism includes a mounting plate, an mounting tube is embedded in the lower end of the mounting plate, a support column is installed in the mounting tube, a flanging head is disposed at the upper end of the support column, the upper end of the flanging head is tapered, a spring is disposed in the mounting tube outside the support column, and the support mechanism includes a positioning seat disposed in the mounting tube, the positioning seat is mounted on the upper end of the spring, and a support plate is arranged in an array on the upper part of the positioning seat.

[0006] Preferably, the positioning seat is a frustum-shaped structure with a larger bottom and a smaller top, the lower diameter of the positioning seat is adapted to the inner diameter of the mounting tube, and the upper part of the positioning seat extends above the mounting plate.

[0007] Preferably, the positioning seat has a through extension hole, the size of which is adapted to the size of the flange head, and the flange head is located inside the extension hole.

[0008] Preferably, the support plate includes a support portion and a positioning portion. The support portion is fan-shaped, and the positioning portion is bent at ninety degrees and located at the end of the support portion. The positioning portion is arc-shaped.

[0009] Preferably, the upper end of the mounting plate is provided with a limiting groove adapted to the shape of the support part, and the limiting groove is provided with a positioning hole adapted to the shape of the positioning part. The positioning part passes through the positioning hole, and the lower end of the positioning part is fitted with a limiting plate by bolts.

[0010] Preferably, the upper end of the mounting plate is provided with a mounting frame, the upper end of the mounting frame is provided with a hydraulic device, the hydraulic rod of the hydraulic device extends to a pressure plate installed below the mounting frame, and a flanged tube is embedded in the pressure plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, through the design of a support plate structure, features an arc-shaped positioning part that can position the support plate as it moves up and down, and a fan-shaped support part that increases the area supporting the workpiece. When the workpiece is subjected to pressure from above, the pressure can be distributed more evenly, avoiding pressure concentration that could cause deformation of the workpiece. This helps ensure the quality of automotive seat components and solves the problem that the current support plate has a small contact area with the workpiece, and that pressure concentration when the workpiece applies pressure to the support plate can easily cause deformation of the workpiece, which is detrimental to the quality of automotive seat components.

[0013] 2. This utility model also incorporates a spring structure. When pressure is applied to the workpiece, the spring can buffer the pressure, thereby protecting the equipment and improving its service life. When the support mechanism loses its downward force, the spring can cause it to rise back to its original position, allowing the flanging head to automatically disengage from the flanging hole of the seat component, making it easy to remove the flanged seat component.

Detailed Implementation

[0021] like Figures 1 to 6 As shown, this utility model relates to a high-efficiency flanging mold for automotive seats, including a lower flanging mechanism 100 and an upper flanging mechanism 200 and a support mechanism 300 provided on the lower flanging mechanism 100. The lower flanging mechanism 100 includes a mounting plate 101, with a mounting tube 102 embedded in the lower end of the mounting plate 101. A support column 104 is installed inside the mounting tube 102, and a flanging head 105 is provided at the upper end of the support column 104. The upper end of the flanging head 105 is tapered. A spring 103 is provided inside the mounting tube 102 outside the support column 104. The support mechanism 300 includes a positioning seat 301 provided inside the mounting tube 102. The positioning seat 301 is installed on the upper end of the spring 103, and a support plate 302 is arranged in an array on the upper part of the positioning seat 301. This invention features a special support structure that not only enables effective positioning but also distributes pressure more evenly during operation, preventing pressure concentration that could lead to deformation of the workpiece and thus ensuring the quality of automotive seat components.

[0022] Specifically, the positioning seat 301 is a frustum shape with a larger bottom and a smaller top. The lower diameter of the positioning seat 301 matches the inner diameter of the mounting tube 102, and the upper part of the positioning seat 301 extends above the mounting plate 101. The frustum shape of the positioning seat 301, with its lower diameter matching the inner diameter of the mounting tube 102, ensures stable installation within the mounting tube 102 while allowing the upper part to extend above the mounting plate 101, facilitating the installation of the support plate 302 and supporting the machined parts.

[0023] Furthermore, the positioning base 301 has a through-hole, the size of which is adapted to the size of the flanging head 105, and the flanging head 105 is located within the through-hole. The positioning base 301 has an extension hole that is adapted to the size of the flanging head 105, so that the flanging head 105 is located within it, which plays a certain guiding, positioning and protection role for the flanging head 105, ensuring the positional accuracy of the flanging head 105 during the working process, and further ensuring the quality of the flanging process.

[0024] It is worth noting that the support plate 302 includes a support portion 3021 and a positioning portion 3022. The support portion 3021 is fan-shaped, and the positioning portion 3022 is bent at ninety degrees and located at the end of the support portion 3021. The positioning portion 3022 is arc-shaped. The arc-shaped positioning portion 3022 of the support plate 302 can position the support plate 302 when it moves up and down. The fan-shaped support portion 3021 of the support plate 302 can increase the area of ​​support for the workpiece, avoiding deformation of the workpiece caused by pressure concentration.

[0025] It is worth mentioning that the upper end of the mounting plate 101 has a limiting groove 106 that matches the shape of the support part 3021. The limiting groove 106 has a positioning hole 107 that matches the shape of the positioning part 3022. The positioning part 3022 passes through the positioning hole 107, and the lower end of the positioning part 3022 is bolted to a limiting plate 303. The limiting groove 106 limits the downward distance of the support part 3021, the positioning hole 107 positions the positioning part 3022 for vertical movement, and the bolted limiting plate 303 secures and fixes the support mechanism 300.

[0026] It is worth noting that a mounting bracket 201 is provided at the upper end of the mounting plate 101, and a hydraulic device 202 is provided at the upper end of the mounting bracket 201. The hydraulic rod of the hydraulic device 202 extends to a pressure plate 203 installed below the mounting bracket 201, and a flanging tube 204 is embedded in the pressure plate 203. When the flanging head 105 enters the flanging tube 204, it forms a flanging cavity, which shapes the vertical edge formed by the hole edge within the flanging cavity. This helps to ensure the shape and dimensional accuracy of the flanging and improves the flanging quality of the automotive seat components.

[0027] Working Principle: This embodiment provides a high-efficiency flanging mold for automotive seats. In use, the automotive seat component is placed on the upper end of the support plate 302. The upper end of the flanging head 105 is positioned inside the hole of the automotive seat component. The hydraulic device 202 operates to lower the pressure plate 203 to apply pressure to the seat component, thereby causing the support mechanism 300 to descend. This allows the flanging head 105 to extend from the upper end of the positioning seat 301. The flanging head 105 can squeeze the hole of the seat component, turning the hole edge into a vertical edge. After the flanging head 105 enters the flanging tube 204, it forms a flanging cavity. The vertical edge turned into the hole edge enters the flanging cavity for shaping, thus performing the flanging work on the automotive seat component. After the flanging is completed, the hydraulic device 202 operates to raise the pressure plate 203 back to its original position. The support mechanism 300 loses its downward force, and under the action of the spring 103, the support mechanism 300 can rise back to its original position. This allows the flanging head 105 to automatically disengage from the hole of the seat component, making it easy to remove the flanged seat component.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
