Abstract

The invention discloses an automobile steel plate spring machining die. The automobile steel plate spring machining die comprises an upper die plate (1) connected with a lathe, upper die bodies (3) arranged on the upper die plate (1), a lower die plate (2) arranged on a punch press, lower die bodies (4) arranged on the lower die plate (2), an abutting plate (7) arranged on the lower die plate (2),middle cushion blocks (5) arranged between the lower die bodies (4) and the abutting plate (7), and cushion plates (8) arranged between the middle cushion blocks (5) and the abutting plate (7), wherein the lower die bodies (4) are arranged on the two sides of the abutting plate (7); the punch press controls the upper die plate (1) to move so as to control the upper die bodies (3) to move, by increasing or decreasing the number of the cushion plates (8) and through mutual effect of the upper die bodies (3), the lower die bodies (4) and the middle cushion blocks (5), steel plate springs arranged between the upper die plate (1) and the lower die bodies (4) are machined with different bending degrees.

Description

technical field [0001] The invention belongs to the field of processing molds, and in particular relates to a processing mold for automobile leaf springs and a processing method thereof. Background technique [0002] Leaf spring is the most widely used elastic element in automobile suspension. It is composed of several alloy spring pieces of equal width but unequal length (thickness can be equal or not). An approximately equal strength elastic beam. Leaf springs constitute the shock absorbers of some cars now. There are many specifications and models of car shock absorbers, and the bending angles are different, so the specifications and models of the leaf springs are also different, and the curvature is also different. If designing a bending mold for each type of shock absorber, it will increase a lot of cost, and the mold must be replaced each time the shock absorber is reprocessed. Contents of the invention [0003] The main purpose of the present invention is to provi...
