1. Customer profile

Zhejiang Wangu Electric Co., Ltd. is a backbone enterprise specializing in the production of high and low voltage switchgear, and is one of the leading enterprises in the domestic electrical cabinet industry. Since its inception, Wangu has been continuously pioneering and innovating in the field of high and low voltage switchgear, improving serialized products to meet the needs of market customers, and is a modern enterprise integrating the design, development, production and sales of high and low voltage switchgear cabinet. The products include high and low voltage switchgear cabinet, inflatable cabinet, power cabinet, ring network cabinet and other complete sets of equipment cabinet, which are widely used in power system, water power generation, airport construction, chemical industry and other industries.

2. Business challenges

The development of high and low voltage distribution cabinet industry is closely related to the fixed assets investment market, its market capacity is closely linked to the development of the power industry, with China's proposed to vigorously develop "new infrastructure" construction goals, China's grid infrastructure construction scale will continue to increase, high and low voltage distribution cabinet market demand will also grow. In order to improve the production capacity of electrical switchgear, Wangu Electric based on various production links to improve efficiency, analysis found that the processing of electrical cabinet shell sheet metal parts is the efficiency of the entire production chain, especially the large batch of cabinet side panels and panel workpieces, the bending process is relatively complex, and the workpiece is up to two meters long, weight more than 30 kilograms. It takes two people to lift the material to complete the short side, which is very tiring and time-consuming, for the sheet metal master to recruit workers at the moment, many young people see the hard work of sheet metal workshop, and the bending work will be discouraged. To this end, at the end of 2019, Wangu Electric actively sought a highly efficient automatic bending equipment that could replace manual bending, and the ability of Yawei robot bending unit matched Wangu's needs.

3. Solutions

Yawei focuses on sheet metal processing equipment, and through years of accumulation, the products basically cover the whole metal sheet processing industry chain, and gradually develop from CNC single machine to automatic unit and flexible production line. This project provides Wangu Electric with an automatic bending unit customized by Yawei machine tool for the electrical industry. Through the strong combination of Yawei's special bending machine for electric cabinet and German KUKA industrial robot, and equipped with a multi-functional pneumatic flattening bending mold, the robot can realize the automatic centering, bending, turning and palletizing of the side panels and panels of the central cabinet after grasping the workpiece. The powerful KUKA robot can continuously process dozens of workpieces, and the entire processing unit can be unmanned.

4. Customer revenue

Through the purchase of Yawei automatic bending processing unit, the processing efficiency of the sheet metal shell in the cabinet of Wangu Electric has been improved by quality. For example, the high and low cabinet side panels in the above figure, the robot automatically completes the four-sided bending in only 2 minutes, while the original two people took 4 minutes to complete, and the accuracy of the bending Angle has also been improved to within 30 minutes, which can be said to improve quality and efficiency. More importantly, because the robot has replaced the manual completion of this kind of high-intensity physical work, the work of sheet metal workers in the workshop has become easier, and the robot has tirelessly processed a batch of workpieces, and everyone unanimously cast a positive eye!

"Force pulling mountain Xi gas world", powerful robots will become the right-hand arm of modern factories, highly flexible Yawei bending unit will also contribute inexhaustible power for smart factories!
