Applications of Bow-Type Press Fitting Machines in Automobile Manufacturing

Bow-type press fitting machines (also known as C-type press fitting machines) are widely used in automobile manufacturing. Their open C-shaped structure, flexible operation, and multi-functionality make them ideal for production scenarios involving numerous automotive parts and high assembly precision requirements. Below is a sharing from Jianlong Hydraulic Technology for your reference!

2. Key Considerations for Selection and Use

When selecting a bow-type press fitting machine for the automotive industry, the following points should be emphasized:

2.1 Precision and Process Control

• Key Requirements: The automotive industry has strict requirements for the displacement-pressure curve of the press fitting process, requiring real-time monitoring and 100% recording to ensure traceability of the press fitting quality of each part.

• Equipment Requirements: The machine must be equipped with high-precision pressure sensors and displacement encoders, and have pressure/displacement monitoring and early warning functions.

2.2 Efficiency and Automation Integration

• Key Requirements: Adapt to the high-paced production of the automotive industry and reduce manual intervention.

• Equipment Requirements: Servo electric or servo hydraulic drives are preferred, with programmable and stable speeds. The machine body should have standardized interfaces for easy integration with robots, conveyors, PLCs, etc., to achieve automated loading and unloading.

2.3 Safety and Reliability

• Key Requirements: Meet factory safety standards; the equipment must be durable and have a low failure rate.

• Equipment Requirements: Must be equipped with safety light curtains, two-hand buttons, and anti-fall devices. Structurally, it should possess sufficient rigidity and good long-term precision retention to adapt to high-intensity continuous operation.

Currently, bow-type press fitting machines are developing towards intelligent press fitting, the core of which is to transform the press fitting process from "outcome judgment" to "process control." For example, when press fitting bearings, the equipment will compare the pressure and displacement curves in real time and match them with the preset ideal curve. If any deviation occurs, an alarm will be triggered immediately, eliminating defective products at the source.
