Embodiment Construction

[0029] The present invention will be further described in detail through the accompanying drawings and specific embodiments below.

[0030] As shown in the figure, this embodiment provides a process for efficiently forming a composite material leaf spring, including the following steps:

[0031] (1) Model the leaf spring, and model the leaf spring model hierarchically from bottom to top to form N (2, 3, 4...) single-layer models stacked together, that is, the first single-layer model , the second single-layer model...the Nth single-layer model, the first single-layer model, the second single-layer model...the width of the Nth single-layer model is equal, and the curvature of the contact surface of the upper and lower adjacent single-layer models corresponds; The principle of determining the number of layers is based on the maximum cutting depth of the ultrasonic cutting equipment, that is, in order to make the maximum thickness of the layered single-layer model less than the m...

Abstract

The invention discloses a process for high-efficiency molding of a composite plate spring. The process comprises the following steps: (1) subjecting a plate spring to modeling and carrying out layeredmodeling on a plate spring model from bottom to top; (2) preparing a curved-surface workbench according to each single-layer model; (3) separately carrying out paving and pasting on each curved-surface workbench by using an automatic tape laying machine so as to form a whole piece of a blank material and cutting the whole piece of the blank material with a cutting machine so as to form a plurality of single blank materials with the same structure; and (4) piling up the plurality of single blank materials and carrying out compression molding so as to form the plate spring. With such a technical scheme, the process for high-efficiency molding of the composite plate spring greatly improves the production efficiency of the composite plate spring prepared through molding and can realize automatic batch production of the composite plate spring.

Description

technical field [0001] The invention relates to a process method for efficiently forming a composite material leaf spring, and belongs to the production technical field of a composite material leaf spring for automobiles manufactured by a molding process. Background technique [0002] At present, most domestic commercial vehicles use longitudinal leaf spring suspensions. Leaf springs are the most widely used elastic components in longitudinal leaf spring suspensions. They are composed of several alloy springs of equal width but unequal length. An elastic beam of approximately equal strength, when the car is running, the load on the frame is transmitted to the loading box through the leaf spring, and then to the axle, during which the elastic deformation of the leaf spring acts as a buffer. The leaf spring has simple structure, low cost, convenient maintenance, and can play a guiding role, and the friction between the plates can also have a certain damping effect. However, t...
