Description

TECHNICAL FIELD

[0001] The utility model relates to air spring skin bag cutting machine technical field, concretely relates to an air spring skin bag automatic cutting machine. BACKGROUND

[0002] Air spring is a kind of elastic element using the elastic force generated by air compression to realize buffering, supporting and other functions. The working principle of air spring is based on the compressibility of gas; a certain pressure gas is filled in a sealed container (usually the structure formed by the combination of rubber skin bag and metal piece), when subjected to external force, the volume of gas in the container changes, and the pressure changes accordingly, thereby generating elastic recovery force to resist external force, so as to realize the effect of buffering and supporting. Air spring skin bag is the core component of air spring, and the performance of air spring skin bag directly affects the overall performance of air spring, and further determines the operation quality of related equipment or system; such as in vehicle suspension system, air spring skin bag is related to driving comfort and stability; in industrial equipment, air spring skin bag affects the vibration isolation effect and service life of equipment.

[0003] After the preliminary forming process of air spring skin bag is completed, the required geometric shape and structure are basically formed, and the skin bag needs to be cut according to specific requirements in the subsequent process to achieve the expected size and shape. The process of cutting the air spring skin bag is as follows: the formed skin bag is sleeved on the skin bag mold matched therewith; the skin bag mold is expanded to a certain state, so that the skin bag is fully expanded; according to the parting line naturally formed during parting, the skin bag is accurately cut by cutter; in the cutting process, the cutting path, depth and speed of the cutter are strictly controlled to ensure that the cut is smooth and meets the requirements; after cutting is completed, the cutter is reset, the skin bag mold is recycled to the initial state, and finally the cut skin bag is taken off from the skin bag mold, and the cutting of the skin bag is completed. However, there is no automatic cutting device for air spring skin bag on the market at present, and the existing manual cutting device is low in efficiency and difficult to meet the increasing demand for rapid cutting of air spring skin bag.

[0004] Therefore, the inventor designs an air spring skin bag automatic cutting machine to fill this gap, optimize the cutting process of air spring skin bag and improve product quality and production efficiency. UTILITY MODEL CONTENTS
