传统的曲柄连杆式机械压力机,用于挤压工艺时,冲头与毛坯接触速度较大,两者硬性撞击,会引起模具,特别是冲头的磨损和疲劳损坏,不仅降低模具寿命,而且影响产品质量.本文介绍的偏置式压力机即主要为解决上述问题。通过理论分析计算,所提出的新方案可解决速度问题;在同样扭矩下,可获得较大挤压力;且压机结构紧凑。 Conventional crank-link mechanical presses for the extrusion process, the punch and the rough contact speed, the two rigid impact, can cause mold, especially the punch wear and fatigue damage, not only reduce the mold life, But also affect the product quality.The offset press introduced in this paper is mainly to solve the above problems. Through theoretical analysis and calculation, the proposed new scheme can solve the speed problem; under the same torque, a larger squeezing force can be obtained; and the compact structure of the press machine is obtained.
