Leaf spring bend-forming die

Abstract

The invention discloses a leaf spring bend-forming die which comprises a die base, a movable die core, a fixed die and vibration motors. The movable die core is arranged in the die base, a pressed plate is arranged inside the movable die core, and a positioning column is arranged on the surface of the pressed plate. Guide rods are fixedly connected to the top of the die base and the fixed die is fixedly connected to the tops of the guide rods, wherein connecting ports are formed in the tops of the guide rods and a mounting module is fixedly connected to the top of the fixed die. Hydraulic cylinders are arranged inside the fixed die, and hydraulic bases are evenly distributed at the bottom of the hydraulic cylinder, wherein hydraulic rods are arranged at the bottoms of the hydraulic bases,and an arc-shaped pressing plate is fixedly connected to the bottoms of the hydraulic rods. According to the leaf spring bend-forming die, the plurality of hydraulic cylinders are arranged and the electric expansion links are arranged at the bottom of the pressed plate, so that bending angles of the electric expansion links and the hydraulic rods can be adjusted through the expansion and contraction of the electric expansion links and the hydraulic rods correspondingly to adapt to bending processing of leaf springs of different types. The overall structure is simple, and the practicability ishigh.

Description

technical field [0001] The invention relates to the technical field of leaf spring processing dies, in particular to a leaf spring bending forming die. Background technique [0002] Leaf spring is a leaf spring composed of not less than one piece of spring steel. Leaf springs are commonly used in the suspension of wheeled vehicles, originally known as laminated or bracket springs, sometimes called semi-elliptical springs or trolley springs, it is one of the oldest forms of springs, leaf springs are long circular arcs with a rectangular cross-section shaped spring steel. In the most common configuration, the center of the arc provides the location of the axle, while rings formed at either end attach to the vehicle chassis. For very heavy vehicles, leaf springs can be made from multiple leaves stacked together, usually with progressively shorter leaves. [0003] Most of the leaf spring bending dies on the market are fixed mold cores, and the angle inside the mold core canno...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the present invention provides a leaf spring bending forming die, which solves the problem that most of the leaf spring bending dies on the market are fixed cores, and cannot be molded according to different types of leaf springs. Adjusting the angle inside the mold core has poor overall flexibility and rigidity. It can only process a single-shaped leaf spring, which has certain limitations. At the same time, the leaf spring will be out of position due to the huge impact force during bending The phenomenon of shifting, low precision and poor stability
