"The caliber of the new product line is larger, and the thin-walled products are deformed and not round. How can this' difficult and complex disease 'be cured?"

"What material is the product made of? In which process does the deformation occur? What is the amount of deformation?"

On the afternoon of April 2, under the leadership of the Fenghua District Federation of Trade Unions in Ningbo, Zhejiang Province, an activity of artisans entering the enterprise was carried out in a number of enterprises such as Ningbo Yiji Valve Manufacturing Co., LTD.

On the same day, the national labor model, great country artisans, China Baowu Baoshan Iron and Steel Co., Ltd. skill expert Wang Jun "parachuted" Ningbo One machine Valve Manufacturing Co., LTD., Ningbo Purui Machinery Technology Co., Ltd. to carry out on-site technical guidance, and enterprise trade union cadres and technical backbone face to face to carry out technical discussion activities to help enterprises break the technical bottleneck.

Ningbo Yiji Valve Manufacturing Co., Ltd. is an enterprise with more than 60 years of professional design, production and sales of all kinds of high, medium and low pressure valves. In the exchange, the company's valve production department minister Hu Songjun first threw out the current most troubled him "thin wall products deformation is not round" problem, Wang Jun through discussion exchanges, production site view "diagnosis", quickly gave professional advice and solutions: "you can optimize the process to reduce the amount of cutting, or change the processing method to cut to grinding." In addition, the cooling time can be extended to prevent thermal deformation."

In Ningbo Purui Machinery Technology Co., LTD., Wang Jun was interested in visiting and understanding all kinds of motor shafts, micro shafts, precision shafts and hardware produced by enterprises, and talking with workers. In response to the technical problems proposed by the enterprise, such as "the subsequent process cost increase due to the varying hardness of individual No. 54 steel products in the heat treatment process", Wang Jun put forward a variety of solutions, and took part samples back to study. He also volunteered to leave his contact information.

In addition, Wang Jun also offered suggestions for enterprises to accelerate the intelligent transformation of products: "I hope that our manufacturing enterprises can make more young workers like to enter the workshop through full-line automation transformation and flexible tooling development, and do not do 'tool people'..."
