转向拉杆端部冷缩成形工艺及专用卧式油压机设计

对细长钢管变径都采用热锻缩口,工艺性差,还要进行再加工,费时费料。而采用油压机进行冷缩口,工艺性好,产品规则,不需进行再加工。结合具体产品和工艺,介绍了重型汽车转向拉杆冷缩工艺参数的确定,设备型式的确定,专用卧式油压机的具体设计参数和设计要点。经生产验证,该工艺及专用设备参数合理,能稳定地保证产品工序质量,且高效节能。

Steering Linkage End Shrink Forming Process and Special Horizontal Oil Hydraulic Press Design

Hot forging necking is always employed for diameter reduction of slender steel pipe for which the process performance isn't good due to its long forming time and material waste.But using oil hydraulic press to shrink forming has better process performance,regular product and needn't to reprocess them.Giving examples of product and process,the paper introduces the determination of heavy vehicle steering linkage shrink forming process parameters and corresponding equipment model,and detailed design parameters and essentials of the special horizontal oil hydraulic press.Production demonstrates that parameters of the process as well as special equipment are reasonable and can stably ensure the product procedure quality effectively and energy-saving.
