Description

강제 복귀 기구를 부착한 수동유압식 공구Manual hydraulic tools with forced return mechanism

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 통상의 복귀시를 표시하는 수동유압식공구의 단면도,1 is a cross-sectional view of a manual hydraulic tool indicating the normal return time,

제2도는 강제 복귀의 조작시를 표시하는 수동유압식공구의 단면도,2 is a sectional view of a manual hydraulic tool for indicating the operation of forced return,

제3도는 제1도의 Ⅰ-Ⅰ선 단면도.3 is a cross-sectional view taken along the line I-I of FIG.

Claims (1)

고정자를 향하여 가동자를 왕동시키는 럼과, 그럼을 가동시키기 위한 실린더와, 그 실린더 내에 수동조작으로 압유를 급송하기 위한 프란저와, 상기 럼을 복동시키기 위한 리턴스프링과 상기 럼을 왕동과 복동을 전환하기 위한 전환판을 구비한 수동유압식 공구에 있어서, 상기 전환판을 전환하기 위한 복귀축이, 전환판을 전환하였을시에, 그 복귀축과 계지하는 제1의 강제복귀용 피스톤을 가지며, 그 제1의 강제복구용 피스톤을 상기 복귀축이 전환판의 전환후에 다시 가동하므로서 압유를 급송가능하게 제1의 강제복구용피스톤실에 내장하고, 한편 상기럼에는 제2의 강제 복귀용피스톤을 제2의 강제복귀용피스톤실에 감입시킴과 동시, 제2의 강제복귀용피스톤실을 상기 제1의 강제복귀용 피스톤실에 연통시킨 것을 특징으로 하는 강제복귀 기구를 부착한 수동식 유압공구.A rum for moving the mover toward the stator, a cylinder for operating the grommet, a plunger for manually feeding hydraulic oil into the cylinder, a return spring for double-acting the rum, and a reciprocating and doubling of the rum In a manual hydraulic tool provided with a switching plate, the return shaft for switching the switching plate has a first forced return piston engaged with the return shaft when the switching plate is switched. The forced recovery piston of 1 is incorporated in the first forced recovery piston chamber so that the hydraulic oil can be supplied while the return shaft is restarted after the switching plate is switched, while the second forced recovery piston is provided in the column. And a second forced return piston chamber communicated with the first forced return piston chamber. A hand-operated hydraulic tool. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
