2、机床的结构说明
2. Structural description
本机床主要由床身、床台、底座,主、辅溜板、主机械卡刀刀体、辅液压卡刀体、专用工装、液压系统、电气系统、润滑系统、冷却系统、排屑系统、拉刀、防护等组成。qnryb.com
This machine consists mainly of a body, a bed, a base, main and auxiliary sliding plates, a main mechanical cutting tool body, an auxiliary hydraulic cutting tool body, special-purpose industrial equipment, a hydraulic system, an electric system, a lubrication system, a cooling system, a chip discharge system, broaching tools and guards, etc.
2.1床身、床台、底座均为A3钢板焊接件。消除内应力的方法为焊接后退火,粗加工后进行振动时效处理,半精加工后再次振动时效处理。导板及压板材料采用45#钢,采用表面中频淬火处理,淬火硬度为HRC42-45,淬火深度为2-6 mm。
2.1 The body, the bed and the base are welded from A3 steel plates. The method of stress elimination is quenching after welding, vibration stress relief after rough machining and again after semi-finishing. The guide plate and the press plate are made from 45# steel, and are subject to medium-frequency surface quenching to a hardness of HRC42-45 and a depth of 2-6mm.
2.2主溜板采用整体铸造的形式。主溜板采用长条形燕尾的结构,辅溜板采用直线滚珠导轨的结构,辅溜板及提刀油缸装在主溜板上从而可实现拉刀的全程护送。
2.2 The main sliding plate is cast integrally in a strip-shaped dovetail structure, and the auxiliary sliding plate in a linear ball guide rail structure and mounted on the main sliding plate together with the lifting cylinder for whole-course conveying of the broaching tools.
2.3主卡刀体采用机械弹簧滑套式的结构、辅卡刀体采用液压滑套式的结构。主、辅卡刀体的具体规格待刀具确认后再定。
2.3 The main cutting tool body is in a mechanical spring sliding sleeve structure, and the auxiliary cutting tool body in a hydraulic sliding sleeve structure. The detailed specifications of the main and auxiliary cutting tool bodies will be determined after the tools are confirmed.
