As the head of the innovation studio of the processing branch,，He not only has a set of innovations.，He is also proficient in technical fortifications.。Although the daily work is busy，But he insisted on studying mechanical design and manufacturing all the year round.、Tooling fixture、Processing technology and other professional knowledge，This enables him to integrate knowledge and practice with cutting-edge theory in his work.，Overcome the difficulties encountered in one's work after another。During the processing of Futian pin shaft parts，Due to time constraints、The task is heavy、Fewer personnel，He broke the rules and designed his own tooling.，Reuse the milling machine that has been idle for many years and operate it personally.，One person takes care of three devices，Take the initiative to put into production，To gain time for the completion of the project on schedule；In the processing of Tianjin motor shaft products，Because there are many kinds of products、The number of pieces is small、The length varies，He used his rest time to optimize the NC program.，So that that tool is flexible and convenient，Reduced clamping and tool setting time for each motor shaft，People even named it.“Adjustable slide multipurpose tool”。

   

     Tackling key technical problems to effectively improve the qualified rate of products

      “Through my design.，Two different types of products using the same tooling，The clamping and tool setting time of the motor shaft can be greatly reduced.，And greatly improve that work efficiency and the product qualification rate.”This is recently，At the technical exchange meeting of the processing branch，Li Lei is introducing his new project.。In October this year，Outsourcing task being trial-produced by Hebei Xuangong Processing Branch——Parts of petroleum machinery-Cylinder padeye and connecting plate，The processing efficiency is low under the condition of no tooling positioning，The freedom of adjustment of that workpiece is not limit，Causing random rotation and producing a large number of waste products.。After on-site discussion and study，Li Lei's independent programming design“Exclusive tooling”，Two kinds of workpieces are connected to one tooling and clamped twice to complete the processing.，It not only improves the working efficiency of the machine tool, but also ensures the accuracy of the workpiece.，Moreover, the qualified rate of two different types of products has also been greatly improved.。

      Under the background of the company's transformation and development，“Small micro unit”Continuously expand diversified business，With Fukuda、Trinity、Xugong and other large enterprises have in-depth cooperation.。Every time we face a new subject.，Li Lei will study hard.，Overcome technical difficulties repeatedly，It not only restores the original function of the large horizontal Kunming machine,，Vertical Machining Lathe for Multi-curve Operation，The production capacity of the processing branch has also been gradually improved.，Begin to undertake Futian crane jib one after another、Connecting frame、Equalizer beam、Pin shaft，Sany engine support、Boom、Cylinder bracket and other processing tasks，Especially the Jiejiexi iron roughneck business.，The monthly production capacity is stable at more than 20 units.，The monthly effect can reach more than one million yuan.，It creates favorable conditions for the company to seek new product support points.。

         Lead the team to successfully complete the first batch of prototype trial production

      “The quality of the bearing shell of the experimental part fully meets the requirements.！”When the processing branch receives the feedback from the outsourcing manufacturer Shanxi Zhizheng Company，Li Lei's team was very excited.，This is the result of working day and night.！This export business to the United States，Customers are strict，The accuracy requirement for the position of the 21 threaded holes in the casting bearing housing must be within 0.08mmWithin。After the failure of sample trial production by many well-known domestic manufacturers,，Zhizheng Company holds the idea of trying.，Found Hebei Xuangong Processing Branch。Li Lei is in charge of trial production.，Hold a mobilization meeting at the first time，Team members live and eat on the front line for several days in a row.，Hundreds of times of trial production by using waste materials，Several of the first 21 holes did not meet the position accuracy requirements.。During lunch one day，Li Lei's new apprentice, Xiao Wang, communicated with him.：“Could it be the machine tool error that causes the position of the 21 screw holes of the part to be out of tolerance individually?。”And then，Under the guidance of Master Li Lei，Xiao Wang and the technicians of the production management team calculated the coordinate size of each hole through multiple tests to find the law.，Finally solved the problem of position.，The dimensions of the first batch of trial-produced products are all qualified.，As a result, Hebei Xuangong has officially become a qualified supplier of the customer's bearing shell plate.，The annual effect of this project is more than 200000 yuan.。

      To master numerical control skills，He uses the innovation studio platform to often lead team members to learn computer mechanical drawing together.、On-line programming，Application of Macro Program in Processing Industry，Participated in and completed multiple models of high-end bulldozer planetary carrier、Piston、Piston seat、Trial production of key components such as final drive。In recent years，Under the leadership of Li Lei，The innovation studio maintains more than 20 key technical problems every year.，The qualified rate of quality is close to 100 percent，Upgrading the company's products，It provides technical support to occupy the high-end market at home and abroad.。

#1Pioneer business card：Li Lei，He is currently the head of the Machinery Manufacturing Innovation Studio of the Processing Branch.，In 2015、2016，In 2017, he was awarded the advanced production worker of the company for three consecutive years.，In 2018, he was awarded the title of Young Professional Expert of the Group，In 2020, he was awarded the model worker of Zhangjiakou City and the winner of the May Day Labor Medal.。Since this year，He actively participated in the construction of many key projects of the company.，Tackling key technical problems、Cost reduction, efficiency enhancement and promotion“Two structures”Optimization and other aspects have made significant contributions.。

#2Pioneer motto：The so-called ingenuity is to do only one thing in life.，The original aspiration remains unchanged，From one to the end。

#3Interview notes：Since joining the work，Li Lei has always been rooted in the front line.、Pay in silence，With his excellent level of business,，Become the leader of the innovation studio，Become the trump card of the processing branch。Work hard in the work、Strive for perfection in technology，Li Lei sticks to the front line with responsibility，Practice the new era with practical actions、Take on new responsibilities、New action！
