Description

Technical Field

[0001] The utility model provides a steering wheel skeleton coiling device, which relates to the technical field of coiling devices. Background Art

[0002] The steering wheel is a key component in a car, allowing the driver to control the vehicle's direction. It's typically located in front of the driver, allowing them to turn the steering wheel to change direction. The steering wheel frame is the internal structural framework of the steering wheel, typically made of metal (such as steel or aluminum alloy). Its primary function is to provide support and stability, enabling the driver's operating force to be accurately transmitted during steering. The steering wheel frame is ring-shaped and requires a coiling device to be wound during production.

[0003] When the existing coiling device coils the skeleton blank, since there are only three forming rollers to roll the blank into a circle, the bent blank needs to be manually supported by the staff to prevent it from tilting forward and backward. Sometimes a certain external force needs to be manually applied to assist the skeleton in shaping and preventing the skeleton from deforming. The operation is cumbersome and inefficient. Therefore, we propose a steering wheel skeleton coiling device. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the existing steering wheel frame needs workers to assist in shaping when the coil is formed, which is relatively inefficient.

[0010] Preferably, a notch is provided on one side of the operating table, and a material discharge basket is provided below the notch.

[0011] Beneficial effects of the utility model:

[0012] By setting the guide outer plate and the guide inner plate, the skeleton blank after bending and extrusion can be guided and limited, so that the skeleton can be automatically rounded without the need for manual shaping assistance from staff.

[0018] The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0019] Reference Figures 1 to 4The present invention provides a steering wheel frame winding device, comprising an operating platform 1, a mechanism plate 2 fixedly connected to the operating platform 1, and forming rollers 1 (8) and 2 (9) rotatably mounted on the mechanism plate 2. Forming roller 1 (8) is coaxially fixedly connected to a rotating shaft 14, which passes through the mechanism plate 2 and is coaxially fixedly connected to a gear 1 (15). Gear 1 (15) meshes with gear 2 (16). A motor 17 is fixedly connected to the operating platform 1, and the output shaft of motor 17 is coaxially fixedly connected to gear 2 (16). Specifically, motor 17 drives gear 2 (16) to rotate, which in turn drives the two gears 15 to rotate synchronously. Gear 1 (15) drives rotating shaft 14, which in turn drives forming roller 1 (8). When the blank passes between forming roller 1 (8) and forming roller 2 (9), the blank can be squeezed and bent into a circle.

[0020] Furthermore, if Figure 4 As shown, in the present invention, the second forming roller 9 is rotatably connected to a slider 18. The mechanism plate 2 has a through hole 21 that mates with the slider 18. Limit blocks are symmetrically fixed to the slider 18 on either side. Limit slots 20 that mate with the limit blocks are defined within the through hole 21. A screw 22 is rotatably connected to the top of the slider 18. The screw 22 extends upward through the mechanism plate 2 and is fixed to a hand lever 3. A nut 4 is threadedly connected to the top of the screw 22. Specifically, the hand lever 3 can be used to rotate the screw 22, thereby driving the slider 18 up and down, thereby adjusting the height of the second forming roller 9.

[0021] Furthermore, if Figure 1 As shown, in the utility model, a guide outer plate 5 and a guide inner plate 6 are fixedly connected to the front side of the mechanism plate 2. The guide outer plate 5 and the guide inner plate 6 are both arc-shaped. The guide outer plate 5 and the guide inner plate 6 are used to limit and guide the direction of the bent blank, so that the blank can be automatically rounded without manual assistance from the staff.

[0022] Furthermore, if Figure 1 、 Figure 3 As shown, in the present invention, the distance between the guide outer plate 5 and the guide inner plate 6 gradually increases on the side close to the forming roller 1 8, and on the side close to the forming roller 1 8 and the forming roller 2 9, the guide outer plate 5 and the guide inner plate 6 are in an outward-expanding trumpet shape, which facilitates the blank to enter the inner side of the guide outer plate 5 and the guide inner plate 6.

[0023] Furthermore, if Figure 3 As shown, in the present invention, the side walls of the guide outer plate 5 and the guide inner plate 6 are both rotatably provided with roller needles 19. When the blank contacts the inner wall of the guide outer plate 5 or the guide inner plate 6, the rolling of the roller needles 19 can reduce the resistance to the blank and allow the blank to pass smoothly.

[0024] Furthermore, if Figure 2As shown, in the present invention, an ejection mechanism is provided on the rear side of the mechanism plate 2. The ejection mechanism includes a plurality of ejector rods 12 that pass through the mechanism plate 2, a ejector plate 11 fixedly connected to the ejector rods 12, connecting plates 10 fixedly connected to both ends of the ejector plate 11, and an electric push rod 13 fixedly connected between the connecting plate 10 and the mechanism plate 2. Specifically, after the skeleton is formed, it will remain between the guide outer plate 5 and the guide inner plate 6. At this time, the electric push rod 13 is activated to drive the ejector plate 11 to move. The ejector plate 11 drives the ejector rod 12 to push the skeleton out and then reset it.

[0025] Furthermore, in the present invention, a rubber pad is fixedly connected to the end of the push rod 12. The provision of the rubber pad can avoid leaving an indentation on the surface of the skeleton when the skeleton is pushed out.

[0026] Further, if Figure 1 As shown, in the utility model, a notch is provided on one side of the operating table 1, and a blanking basket 7 is provided below the notch. The pushed-out skeleton can directly fall into the blanking basket 7 for centralized collection.

[0027] Working principle: The blank enters from the left side of the forming roller 1 8 and the forming roller 2 9, and is extruded from the right side after bending. The extruded skeleton enters the inner side of the guide outer plate 5 and the guide inner plate 6, and moves along the path defined by the guide outer plate 5 and the guide inner plate 6, so that it can automatically form a circle without manual assistance from the staff. After the skeleton is formed, the electric push rod 13 is started to drive the push plate 11 to move, and the push plate 11 drives the push rod 12 to push the skeleton out, and the skeleton falls directly into the discharge basket 7 for centralized collection.

[0028] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
