Description

Technical Field

[0001] This invention relates to the field of air spring technology, specifically to an air spring forming machine. Background Technology

[0002] Air springs are made by filling a sealed container with compressed air, utilizing the compressibility of gas to achieve their elastic effect. Air springs possess ideal non-linear elastic characteristics; with the addition of a height adjustment device, the vehicle height does not change with load variations, and the spring stiffness can be designed to be lower, resulting in good ride comfort. However, air spring suspension structures are complex and have high manufacturing costs.

[0003] For example, Chinese patent application number CN200820229147.8 describes an air spring forming machine with a radial shrinkage forming head and a combined pressure roller device. It comprises a molding machine main unit, a combined pressure roller device, a rotating tailstock device, and a machine base. The molding machine main unit is connected to a main shaft via a sleeve shaft, and a radial shrinking molding head is connected to the main shaft. The molding head includes an expansion and contraction main shaft, alternating small and large bearing slides, with small and large bearings respectively mounted on the small and large bearing slides. A pair of drive seats and guide sleeves are fitted on the expansion and contraction main shaft, and an expansion and contraction tie rod is installed inside the cylindrical expansion and contraction main shaft. The expansion and contraction tie rod is connected to the drive seat via a connecting pin. The combined pressure roller device consists of a triangular base, a rectangular carriage, a tread rolling assembly, and a drive device.

[0043] The control panel 6 is fixedly installed on the support platform 1.

[0044] Furthermore, it also includes a pressing mechanism 7, which is located below the forming cylinder mechanism 2 and fixedly installed on the support platform 1. The pressing mechanism 7 includes a second lateral displacement component 71, on which a third cylinder 72 is installed. A pressing wheel 73 is fixedly connected to the telescopic end of the third cylinder 72. A large ring fixing component 74 fixedly connected to the displacement part of the second lateral displacement component 71 is provided on the left side of the third cylinder 72. Through the second lateral displacement component 71, the pressing wheel 73 on the third cylinder 72 can be moved to achieve the pressing of the air spring rubber part. It can also move the metal ring placed on the large ring fixing component 74 to a certain position to achieve rubber covering of the metal ring, thereby completing the shaping of the large ring of the air spring.

[0045] Furthermore, the small-circle reverse wrapping forming mechanism 5 also includes a covering ring 58, and a second cylinder 56 with a telescopic end fixed to the covering ring 58 is installed on the moving frame 52; by extending the telescopic end of the second cylinder 56, the covering ring 58 can be moved, so that its converging inner cavity fits against the right side of the rubber cylinder, causing it to fold to the left, and then the reverse wrapping part can be pressed by the pressing wheel 73.

[0046] Furthermore, magnets 514 are uniformly fixed to the outer side of the small ring fixing ring 59. The magnets 514 are used to attract the metal ring wrapped around the small opening.

[0047] Furthermore, the small-ring expansion mechanism 4 includes an airbag fixing mechanism 41 installed at the right end of the forming cylinder mechanism 2 and an air pipe 45 passing through the central shaft 21.

Each set of clamping arms 742 is equipped with a clamping head 744 with an arc-shaped clamping part, and a rubber layer 745 is provided on the clamping head 744. By controlling the extension and retraction of the extension and retraction ends of the two sets of sixth cylinders 743, the two sets of clamping arms 742 can be brought closer and further apart, thereby clamping and fixing the metal ring at the large ring opening.

[0050] Furthermore, the large-aperture reverse-wrapping forming mechanism 3 includes a sliding cylinder 31 sleeved on the central shaft 21. A first drive plate 32 is rotatably connected to the left side of the sliding cylinder 31. A fourth cylinder 33 with a telescopic part fixed to the first drive plate 32 is installed on the support platform 1. A sliding ring 34 is slidably connected to the outside of the sliding cylinder 31. A second drive plate 35 is rotatably connected to the sliding ring 34. A fifth cylinder 36 with a telescopic part fixed to the first drive plate 32 and fixed to the second drive plate 35 is fixed to the first drive plate 32. A reverse-wrapping toothed ring 37 is fixed to the outer wall of the right end of the sliding ring 34. A hinge seat 38 is fixed to the right end of the sliding cylinder 31. A first support rod 39 is evenly hinged to the hinge seat 38. A second support rod 39 is hinged to the forming cylinder 22. A spring 311 sleeved on the central shaft 21 is provided between the support rod 310, the sliding cylinder 31, and the forming cylinder 22. By controlling the extension end of the fourth cylinder 33 to extend, the first drive plate 32 can be moved, thereby causing the sliding cylinder 31 to move to the right. This causes the hinge joints of multiple sets of first support rods 39 and second support rods 310 to be opened outward, so that the rubber wrapped around the outside of the first support rods 39 and second support rods 310 is expanded until it fits against the inner wall of the large-mouth metal ring. Then, by controlling the fifth cylinder 36 to drive the sliding ring 34 to move the reverse-wrapping toothed ring 37 to the right, the rubber that exceeds the large-mouth metal ring can be reverse-wrapped over its outer surface. With the rotation of the pressure wheel 73 and the forming cylinder mechanism 2, the forming of the large-mouth ring can be achieved.

[0051] Furthermore, the reverse-wrapping toothed ring 37 includes a toothed ring body 371, on which are uniformly provided clearance openings 372 arranged in a circumferential array, the clearance openings 372 being used to avoid the first support rod 39 and the second support rod 310.

[0052] A specific application of this embodiment is as follows: This invention is an air spring forming machine. When in use, the rubber sheet for forming the air spring is brushed with glue and wrapped layer by layer on the forming cylinder mechanism 2, with both ends extending beyond the forming cylinder mechanism 2. During the wrapping process, the drive motor 23 can be controlled to drive the central shaft 21 to rotate, thereby realizing the rotation of the forming cylinder 22, which is used to assist in wrapping the rubber sheet to form a rubber cylinder. During the wrapping process, the second lateral displacement component 71 on the pressing mechanism 7 can drive the pressing wheel 73 on the third cylinder 72 to move, and the extension and retraction of the extension end of the third cylinder 72 can be adjusted to achieve the pressing of the air spring rubber sheet.

[0053] After the rubber cylinder for air spring molding is formed, the large-diameter metal ring is placed on the large-diameter fixing member 74 and clamped. The second lateral displacement member 71 drives it to move to the limited position of the large-diameter opening. By controlling the extension end of the fourth cylinder 33 to extend, the first drive plate 32 can be moved, thereby driving the sliding cylinder 31 to move to the right. This causes the hinge joints of multiple sets of first support rods 39 and second support rods 310 to be opened outward, so that the rubber wrapped around the outside of the first support rods 39 and second support rods 310 is expanded until it fits against the inner wall of the large-diameter metal ring. Then, by controlling the fifth cylinder 36 to drive the sliding ring 34 to drive the reverse wrapping toothed ring 37 to move to the right, the rubber that exceeds the large-diameter metal ring can be reversed over its outer surface. With the rotation of the pressure wheel 73 and the molding cylinder mechanism 2, the large-diameter opening can be formed.

[0054] Forming the small coil of the air spring: First, the small coil metal ring is attracted to the magnet 514. Then, the extension end of the first cylinder 55 is controlled to retract, which drives the moving shaft 54 ​​to push the gripper 511 out of the mounting cylinder 57. After the gripper 511 is freed from the restriction of the mounting cylinder 57, it opens outward under the action of elasticity. Next, the first lateral displacement component 51 is controlled to drive the moving frame 52 to move to the left until the gripper 511 can grip the right end of the rubber cylinder. Then, the extension end of the first cylinder 55 is controlled to retract, which drives the gripper 511 to grip the right end of the rubber cylinder and bring it inward. Then, the moving frame 52 is driven to move to the left. The moving frame 52 moves to the left, causing the small metal ring attracted to the magnet 514 to abut against the outer wall of the rubber tube. Then, by inflating the airbag 42, the airbag 42 can be expanded, thereby pushing the right side of the rubber tube outward. During the expansion of the airbag 42, the moving frame 52 moves to the right, and the mounting cylinder 57 makes way for the right end of the rubber tube to fold outward. Then, by extending the telescopic end of the second cylinder 56, the covering ring 58 can be moved, so that its converging inner cavity fits against the right side of the rubber tube, causing it to fold to the left. The pressure roller 73 presses the reverse wrapping part to achieve the covering of the small metal ring.

[0055] After completing the forming of the large and small rings, the rubber tube of the air spring can be disengaged from the forming tube mechanism 2.
