Automobile leaf springs are the main elastic components of automobile suspension systems at home and abroad. With the continuous advancement of science and technology, lightweight design of automobile leaf springs has also been widely used. The demand for variable-section leaf spring products for semi-trailers at home and abroad is increasing. The variable-section products of semi-trailers have fixed characteristics such as short fulcrum distance, uniform size, small number of pieces and light weight. The current assembly line is divided into four stations: swinging pieces, center bolts, pre-compression and unloading. The total power consumption is generally 30 kilowatts, 4 people are employed, and the maximum output can reach 500 pieces / shift. First, the operator at the leaf-swinging station places the spring leaf on the spring-loading seat of the assembly line; after the spring-loading seat with the spring leaf moves to the center-bolt station, the operator at this station starts the leaf spring clamping device to clamp the spring leaves and tightens the bolts to form a leaf spring assembly; the leaf spring assembly with the center bolt tightened moves to the pre-stressing station, and the operator at this station starts the pre-stressing device to pre-stress the leaf spring assembly and tightens the bolts again; the pre-stressed leaf spring assembly moves to the next workpiece station, and the operator at this station transfers the leaf spring assembly rack to the next process.
