Description

Technical Field

[0001] The invention relates to the technical field of air spring bladder cutting equipment, and in particular to an automatic air spring bladder cutting equipment. Background Art

[0002] An air spring is an elastic element that uses the elastic force generated by compressed air to achieve functions such as cushioning and support. The working principle of an air spring is based on the compressibility of gas; a sealed container (usually a structure composed of a rubber bladder and metal parts) is filled with gas at a certain pressure. When subjected to external force, the volume of the gas in the container changes, and the pressure changes accordingly, thereby generating an elastic restoring force that counteracts the external force, thereby achieving a cushioning and supporting effect. The air spring bladder is the core component of the air spring. The performance of the air spring bladder directly affects the overall performance of the air spring, and thus determines the operating quality of related equipment or systems; for example, in a vehicle suspension system, the air spring bladder is related to driving comfort and stability; in industrial equipment, the air spring bladder affects the vibration isolation effect and service life of the equipment.

[0003] After the initial molding process, the air spring bladder basically forms the required geometric shape and structure. The bladder needs to be cut according to specific needs to achieve the expected size and shape. The process of cutting the air spring bladder is to put the formed bladder on the matching bladder mold; expand the bladder mold to a predetermined state so that the bladder is fully unfolded; according to the parting line naturally formed during parting, the bladder is accurately cut by a cutter; during the cutting process, the cutting path, depth and speed of the cutter are strictly controlled to ensure that the cut is flat, smooth and meets the requirements; after the cutting is completed, the cutter returns to its original position, the bladder mold is recovered to its initial state, and finally the cut bladder is removed from the bladder mold to complete the cutting of the bladder. However, there is currently no automatic cutting equipment specifically for cutting air spring bladders on the market, and the existing manual cutting equipment is inefficient and difficult to meet the growing demand for rapid cutting of air spring bladders.

[0004] Therefore, the inventor carefully designed an automatic cutting device for air spring bladders, aiming to fill this gap, optimize the cutting process of air spring bladders, and improve product quality and production efficiency. Summary of the invention
