Stretch Machine Casing Precision Hardware Components

English Translation: The stretching machine housing is an integrated shell component processed by precision stretch forming technology. It is mainly used to enclose and protect the core components of stretching equipment (such as motors, hydraulic systems, transmission mechanisms, etc.), while undertaking functions such as positioning and assembly, heat dissipation and protection. With the characteristics of high forming precision, excellent structural strength and good surface quality, it is widely used in the field of high-end equipment manufacturing and is a key structural component ensuring the stable operation of stretching equipment.English Translation:High-precision forming: Adopting multi-pass shallow stretching technology, the diameter tolerance can be precisely controlled, and the flatness error is small, ensuring tight fitting with supporting components and avoiding assembly jamming or excessive gap problems;Excellent structural strength: After cold working hardening treatment, the product strength is increased by 20%-40% compared with the raw material. Combined with the built-in reinforcing rib design, it can effectively resist vibration and pressure during equipment operation and reduce deformation risks;Good surface quality: The stretched surface is smooth without burrs, the cut surface is neat, the Ra value can reach 0.8-1.6μm, and it can meet assembly or appearance requirements without additional grinding;Efficient heat dissipation and protection: Some models integrate heat dissipation holes, thermal conductive silica gel and heat sink fin structures, which can quickly dissipate heat generated by internal components; at the same time, they have dustproof and moisture-proof functions to avoid debris intrusion affecting equipment life.

English Translation:1. Common materials: According to application scenarios, stainless steel (304/316), aluminum alloy (5052), low-carbon steel (DC04/SPCC), etc. can be selected. Among them, stainless steel has good electrical conductivity, thermal conductivity and corrosion resistance, making it the preferred choice in the electronic and automotive fields; aluminum alloy has significant lightweight advantages and is suitable for equipment with strict weight requirements;2. Key processes: The core process includes blank preparation → lubrication treatment → primary stretching → annealing stress relief → precision stretching → trimming and shaping. By precisely controlling the stretching coefficient (first stretching coefficient 0.5-0.6), mold gap (1.1-1.3 times the material thickness) and lubrication conditions, the stability and consistency of product forming are guaranteed.English Translation: It covers multiple fields such as electronic appliances (micro motors, sensors, lithium battery casings), automobile manufacturing (automobile body panels, seat parts, battery casings), aerospace (aircraft skin components), home appliance industry (refrigerator/air conditioner panels, washing machine inner drums), new energy (solar brackets, fuel cell bipolar plates), etc., and can adapt to the customization needs of stretching equipment of different tonnages.
