“These five beams, whether from the product size or the appearance quality, are much better than the imported parts! The beam or Dongfeng mold is doing well! We have 8 beams that are ready to be given to Dongfeng Mould!†This is a statement made by Jiangling Motors Co., Ltd., who is responsible for the frame manager Xu Xu’s speech to Li Benyan, the chief engineer of Dongfeng Mould Manufacturing Technology.
Project weight: 25 parts 85 sets of mold
Jiangling V348 mould project is a “bulk†mold development and manufacturing project signed by Jiangling Motors Co., Ltd. and Dongfeng Auto Mould Co., Ltd. at the end of June 2005. A total of 25 parts 85 sets of molds, from October last year, in strict accordance with the provisions of the contract in three batches of shipments. As of June 10, for a period of two years, the third batch of molds for the Jiangling V348 project had all been credited to users.
"The characteristics of this mould project are many beam parts and a total of 10 beam parts. Therefore, in the development design, the first is to optimize the stamping process and mold structure design, and to predict in advance the rebound and distortion of the parts during the actual debugging process. Such phenomena, Second, in the process of manufacturing and debugging, to develop a reasonable solution, because the beam parts of the press pressure, mold clearance requirements are very sensitive, parts change is very sensitive, the size is not easy to control, need repeated modification, repeated debugging."
Talking about the Jiangling Mould Project, Mr. Ren Qian, the director of the company's mold adjustment workshop, talked about everything in a row. “The second point is the top cover mold, which is up to 4 meters in length and draws a depth of 0.4 meters. This is by far the biggest cover our mold company has undertaken.â€
High difficulty: 1 part 7 rounds of debugging
The rebound problem of beams is a difficult problem to overcome and is well known in the mold industry. “When debugging the stringer parts, Zhou Bo, Zhou Yuchun and other staff faced difficulties in rebounding complex parts, but never thought of retreat. Instead, they turned round and round, repeatedly feeding parts, and when the most difficult The issue of bombs was solved. The problem of pulling parts on the side of the parts came one after another. A maximum of one part was changed to seven rounds, which lasted six months." Li Cheng, director of the Jiangling project, said.
When debugging the beam mold, Hua Lianhan, marketing manager of the marketing department, told the writer about an episode. “At the time, when Jiangling users saw that it was difficult to debug the parts and the mold progress was not very smooth, they invited a mold debugging expert from Turkey to make a special visit to the mold company to conduct 'consultation', and the proposed proposal could not change the status quo of the parts. Under this circumstance, we still haven't given up on the mold and still hold the concept of being responsible for the users. Under the guidance and bold innovation of the chief division of Li Benyan, the employees are united and overcome the difficulties in mold debugging."
Sunge is one of the debugging beam components. Relying on the hard skills hard-working in daily work, he repeatedly pondered the root of the problem in the debugging of the mold and formulated a solution. When the user saw the product size of the part that was debugged when the mold was accepted, the size of the part was more in line with the product definition than the KD part. Thumbs up helplessly: "Dongfeng's workers are amazing!"
Rectification more: more than 40 pages more than 200 children
Die is a technology-intensive industry, mold production is the order of production, is based on user needs and continuous improvement, after the end of the mold manufacturing, the user acceptance, in order to better customer satisfaction, and the user's current production beat "in tune." , To adapt to the user's equipment and production conditions, mold rectification has become a key part to improve the quality of parts.
In February of this year, the acceptance inspection team of the Jiangling mold project began acceptance of the third batch of molds. For this purpose, the rectification work began. The clamp adjustment workshop dispatched 6 elite troops to establish the Jiangling Project Rectification Team, and Luke took the lead.
"For two consecutive months, Luc led five team members to debug and rectify more than 30 sets of molds. To ensure the progress, Yamashita's press adjustments were attributed to them as 'unique', in the case of tight deadlines and low manpower. According to the requirements of the user node to complete the task of rectification of more than 40 pages for more than 200 subitems!†said Lu Zhigang, the dispatcher of the clamp adjustment workshop, to the author.
Next to the press in the workshop, the author finally found Luce who was giving the mold to Nissan. An angular face, handsome and handsome, always with hearty laughter in his speech. Recalling the days of Jiangling's rectification some time ago, it was a word and it was exhausting, but it was also worth seeing when the third batch of JMC molds were sent away from their hands, and the feeling of pride was over.
“At that time, we generally accompanied the users during the day to accept and check, and at night, rectify the opinions put forward by the users, re-accept the next morning, rectify it at night, and insert the seams in a busy manner to paint and oil the molds. Every day, Fighting for 4 months. In February of this year, there was a week before returning home at 11 o'clock and 12 o'clock and working on time at 8 o'clock the next day.†Luc said as he glared at the mold.
"On a Sunday morning, Luc went to the marketing department to participate in the project promotion meeting and fell asleep while listening. After the meeting, the head of the Yuguan responsible for Jiangling's acceptance inspection was very distressed. It turned out to be "staring at us". I team, took the initiative to ask Luc to rest. "Joining in the side together, participating in Jiangling rectification member Yang Xiaoshui added.
"In this way, I spent half an afternoon to accompany my children to play for an afternoon to make up for the children's feelings." Luc smiled brightly.
“ Through the joint efforts of all the cadres and employees of Dongfeng Mould, in order to let the user not give up and crack the rebound problem of the beam parts of the mold industry, we ensured the forming quality and forming stability of our products and met our production requirements. We are the Dongfeng Mould. I was deeply touched by the philosophy of being responsible for the users!" said the head of the Jiangling Acceptance team sincerely.
