[0002] The steel plate spring is composed of multiple steel plates with different lengths and curvatures. After installation, the two ends are naturally curved upwards. When the impact force of the road on the wheel is transmitted, the steel plate deforms, plays a buffering and damping role, and has a guiding force transmission effect when arranged longitudinally. Non-independent suspension mostly uses a steel plate spring as an elastic element, which can save the guiding device and shock absorber, and has a simple structure.

[0003] In the production process of the steel plate spring, a pressing device is usually used to press the steel plate spring.

Moreover, the pressing device usually uses an extension rod with a pressing block to press the steel plate spring, so that the pressing force of the device on the steel plate spring is limited. To solve the technical problem, the steel plate spring processing pre-pressing equipment is provided. UTILITY MODEL CONTENTS
