The present invention relates to a high speed hydraulic press. At present, the forging time of the hydraulic press is not more than 300 times per minute, and the speed can not meet the needs of mass rapid production. The purpose of the invention is to forging hydraulic machine per minute up to 400 times per minute, the specific measures are: a high speed hydraulic machine, which comprises a body, slider, piston, cylinder block, cylinder bottom, which is characterized in that the cylinder bottom is provided with a sealing plunger, the upper end of the piston is having a tapered hole, live Senegal a drain port, the lower sealing plunger is a plane. A spring support is arranged at the bottom of the cylinder, and a spring is arranged between the spring support and the sealing plunger. The invention of the high pressure oil is filled in the upper part of the piston pressure so that the slider down after the establishment of complete process under high pressure oil pressure at the same time the upper part of the piston to seal oil piston automatically pushed from the upper part of the piston to the high-pressure oil inside the piston quickly to oil tank and short cycle time can ensure the forging times 400 times per minute.
【技术实现步骤摘要】
高速液压机
本专利技术涉及一种高速液压机
技术介绍
目前的液压机,包括所谓的快锻机每分钟的锻造次数都没有超过300次,这种速度不能满足当今大批量块速生产的需要。
技术实现思路
一种高速液压机,包括机身[1],滑块[2],活塞[3],缸堵[4],缸堵螺钉[5],缸堵密封圈[6],活塞密封圈[7],缸底密封圈[8],缸底[10],缸底螺钉[9]缸底进油口[13],缸堵进油口[17],其特征是缸底[10]内装有封油柱塞[15],活塞[3]的上端有锥形口[19],活塞[3]内有泄油口[18],封油柱塞[15]的下端是个平面。缸底[10]上装有弹簧支架[12],在弹簧支架[12]与封油柱塞[15]之间装有弹簧[11]。本专利技术是这样实现的:在机身[1]上装有缸底[10],缸底[10]通过缸底螺钉[9]与机身[1]固定连接,在缸底[10]内装有封油柱塞[15],封油柱塞[15]与缸底[9]滑动连接,封油柱塞[15]上装有封油柱塞密封圈[14],机身[1]内装有活塞[3]活塞[3]与机身[1]滑动连接,缸堵[4]通过缸堵螺钉[5]与机身[1]固定连接,缸堵[4]与活塞[3]滑动连接,活塞[3]上装有密封圈[16],附图说明图1是本专利技术的总体结构图,图2是图1的A部放大图图3是本专利技术的液压原理图,图中有溢流阀[20],电机[21],油泵[22],单向阀[23],压力表[24]三位四通电磁阀[25]。本专利技术的高压油充入活塞上部后建立压力使滑块下行完成压下工序与此同时活塞上部的高压油把封油柱塞自动推开让活塞上部的高压油从活塞内迅速流回油箱,因而循环时间短能确保每分钟 ...
