Hebei Xuangong: Small Technological Innovation and Great Efficiency Improvement
August 16, 2023
Since miniaturization，Cost reduction and efficiency enhancement run through the process of production organization，How to reduce costs and improve efficiency is the focus of the work of the hydraulic branch.。In the pressing process of the high-pressure rubber hose,，There are some rubber hoses as required.，It is required to wrap a layer of protective sleeve on the high-pressure hydraulic oil pipe.，To prevent bumps and play a protective role.。The protective sleeve is generally made of nylon or polypropylene.，Helical sheathed wire manufactured by hot winding shaping extrusion proces，Carry out anti-aging treatment on that outer surface of the rub tub、Protection against corrosion and abrasion。
Most of the hoses originally used by the company are from outside.，The size of the hose collected from outside will be affected.、Single angle problem，Quality requirements cannot be guaranteed after installation。In 2021, the hose team of the hydraulic branch plant began to develop self-made hose.，Carry out technical research on hose production step by step，Realize self-made instead of external mining，And that production cost is reduce.。The existing method for winding the sheath is manual winding.，Its disadvantage is low efficiency.，The labor intensity of operators is high.，With the increase of production tasks of various types of Bulldozers,，More and more hydraulic hoses are needed.，The production efficiency of manual winding sheath has seriously affected the production efficiency of the whole hose assembly.。“Contribution of cost reduction and efficiency increase ratio、Technological upgrading and striving to be the first”Since the launch of the Theme Pioneer Competition，Under the arrangement and guidance of Guo Qiang, director of the branch factory，Party member Li Jiandong、Xiao Jiandong and operator Xing Yongqiang form a hose research team，Decided to make the sheath winding equipment by hand。The principle of technical transformation is to make use of existing machinery.，Make simple and practical equipment，Meet the needs of work，And minimize capital investment.。Combined with the sheath winding video forwarded by Director Guo Qiang，Three Party members and workers actively use their brains to find ways.，Measure the dimensions carefully together.，Discuss, study and determine the technical transformation plan。Scrap channel steel and angle steel were found.，The channel steel is used as the guide frame of the hose.，Angle steel is welded under the guide frame as the support frame，Four universal wheels are installed under the support frame to facilitate movement.。After testing，The rotating speed of the selected rubber stripping machine can just meet the rotating speed of the rubber hose winding，The manufacturing and connecting core shaft is arranged on an unused rubber stripping machine.。When performing the sheath winding operation，Manually wind the sheath wire at one end of the hydraulic hose.，After the end part is wound firmly，Clamp the end on the coupling mandrel，And the other end is connected with a limiting block of the guide frame through a thread.，And the problem of swinging of the rubber tube is solved.，Pedal switch starts the stripping machine，Carry out orderly winding on the sheath wire with an iron hook。Verified by production for many times，The semi-automatic sheath winding equipment is simple in structure.，But is convenient to operate and use.，Reliable performance，Fully meet the company's Bulldozer、Powder loosening machine、Hose sheath winding for tapping machine and social services，And that labor intensity is reduce，And that production efficiency is improve.，The quality is more stable。Xing Yongqiang said，“When winding the sheath by hand，After a few turns, the lower sheath line is twisted together.，You have to wind the lower sheath wire back in reverse.，Very annoying，Longest 3.It takes 25 minutes to wind the 5-meter hose by hand.，I am so tired that my head is dizzy and my hands and feet are numb.，After the improvement, it was wrapped in more than 2 minutes.，10x more efficient，It is very convenient and labor-saving，Solve the big problem of winding。”
