Problems solved by technology
However, the production of sleeve-type air springs is often in large quantities, that is, thousands of sleeve-type air springs of the same model in each batch need to be shaped and curled. Therefore, it is difficult to ensure that each sleeve-type air spring is inflated and curled The shaping height in the process is the same, that is, the height consistency in the shaping and curling process is poor, which seriously affects the production quality and production efficiency of the sleeve air spring

The invention proposes a sleeve-type air spring shaping and curling device and method, wherein the sleeve-type air spring shaping and curling device includes a lifting piece, a power element and a support frame, wherein the top of the lifting piece is provided with a mounting bracket for installing the air spring. Joints, the installation joints are fixedly connected with the lifting parts, there are multiple installation joints, and the multiple installation joints are arranged side by side and at intervals on the same horizontal plane, the power components are fixed on the support frame, and the power components are connected with the lifting parts to drive the lifting parts Lifting movement; the sleeve-type air spring shaping and curling method uses the above-mentioned sleeve-type air spring shaping and curling device. The invention improves the consistency of the height in the shaping and curling process of the sleeve type air spring.
Description
technical field [0001] The invention belongs to the technical field of air spring manufacturing equipment, and in particular relates to a sleeve-type air spring forming curling device and method. Background technique [0002] Compared with traditional steel springs, leaf springs and rubber springs, air springs have obvious advantages in vibration and noise reduction, so they are widely used in automotive and engineering vibration reduction and other fields. There are three types of air springs: sleeve type, membrane type and bladder type. The sleeve type air spring is mainly composed of an upper cover, an upper snap ring, a lower snap ring, a capsule and a piston. It has the advantages of large stroke, obvious vibration reduction effect and wide application. Before installing the sleeve-type air spring, the capsule needs to be shaped and curled to the required height, so that it can be assembled and used with different types of shock absorbers. [0003] According to the ex...
