Leaf Spring Forming Equipment

 

Hydraulic cutting machine

This station completes the bending and cutting of the head of the steel plate material. When rolling the round ears and Berlin round ears, the steel plate is bent with a curvature radius close to the radius of the ear hole, and the head is cut off. In order to reduce the rotation angle when rolling the ears, the head cutter is tilted 30° to the vertical plane in the head cutting part, and the angle between the two sides of the simulated arc surface of the head cutter is 60°, which increases the ear angle at the head cutting and improves production efficiency.

It consists of a head cutting shearing mechanism, a clamping mechanism, a positioning mechanism and other parts.

The head cutting shearing mechanism consists of a frame, a head cutting cylinder, a guide rail, a slide rail, a head cutting knife and a head cutting R mold.

The clamping mechanism consists of a clamping oil cylinder, a guide rod, and a clamping seat;

The positioning mechanism consists of a center pin adjustment mechanism and a width positioning mechanism.

 

Roll-up earphones

This station completes the leaf spring rolling work. According to the different forming processes of the leaf spring, the operator can achieve different process performances after adjusting the equipment and replacing the mold. According to the shape of the ear hole, this machine can complete the forming of flat ears and Berlin ears. Flat ears are subdivided into flat round ears and flat wrapped ears (oval), and Berlin ears are subdivided into Berlin round ears and Berlin wrapped ears (oval); according to the forming method, it can be divided into rolling and wrapping due to the use of clamping blocks or rollers.

It consists of a core pulling device, a coiling ear clamping mechanism, a coiling ear rotating mechanism, a pressing mechanism, a length positioning and a lifting mechanism.

Technical parameters

This product is a non-standard automation product, and the parameters can be adjusted. The following are parameter examples:

The ear curling equipment is used for forming leaf springs with ear thickness (6-20 mm), ear width (50-120 mm), and ear (1000-2000 mm).

3.1. Automotive Industry

Commercial vehicles (trucks, buses): strong load-bearing capacity, can effectively buffer vibrations and improve vehicle stability.

Pickup trucks and SUVs: Some off-road vehicles and light trucks still use leaf springs to enhance load-bearing capacity and durability.

Trailers and trailers: provide better support and durability, suitable for heavy-load transportation.

3.2. Railways and rail transit

Trains and subways: leaf springs are used in bogie suspension systems to provide shock absorption effects and improve ride comfort and safety.

Railway freight cars: Due to their high load-bearing capacity and impact resistance, leaf springs are widely used in railway freight cars.

3.3 Agriculture and construction machinery

Agricultural machinery such as tractors and combine harvesters: leaf springs help equipment stay stable on rugged terrain and reduce vibration damage to mechanical parts.

Construction machinery such as excavators, loaders, cranes, etc.: enhance the durability of the suspension system and improve the equipment's ability to operate in harsh environments.

1) Flat curled round earphones
