The specific embodiment
Shown in Fig. 1, Fig. 3 and Fig. 4, a kind of hydraulic clamp cutter foot pedal apparatus comprises platen oil cylinder 8, is provided with flow control valve 9 in the oil supply loop of platen oil cylinder 8, and foot pedal apparatus 6 cooperates with spool 91 through the push rod 96 in the flow control valve 9.
In Fig. 3, in the described foot pedal apparatus 6, slide block 608 is connected with crank mechanism, and the front end of slide block 608 is provided with an inclined-plane, and an end of the push rod 610 in this inclined-plane and the sliding chute seat 609 is slidingly matched, and the other end of push rod 610 cooperates with push rod 96 in the flow control valve 9.
In Fig. 3, also be provided with adjusting nut 605 on the described push rod 610, the length that can regulate push rod 610 through adjusting nut 605, thus regulate transmission accuracy, reliable for the fixed-site of guaranteeing adjusting nut 605, joint nut 605 1 sides also are provided with locking nut 611.
In Fig. 1, in the described crank mechanism, pedal 602 is fixedly connected with pedal spindle 601 with crank 603, and crank 603 is hinged through connecting rod 606 and slide block 608.Pedal spindle 601 is installed on the cabinet base 604;
In Fig. 3, spool 91 is installed in the housing in the flow control valve 9, and housing is provided with first passage 92, third channel 94 and is communicated with the second channel 93 of first passage 92 and third channel 94;
Spool 91 1 ends cooperate with push rod 610, and the other end is provided with spring;
Spool 91 forms actual internal area cooperating from maximum-0 with first passage 92.
In Fig. 4, in the described oil supply loop, oil pump 3 imports are communicated with oil sump 1, and oil pump 3 outlets are communicated with platen oil cylinder 8, and oil pump 3 is also parallelly connected with a way to cycle oil, and way to cycle oil is communicated with oil sump 1, and way to cycle oil is provided with flow control valve 9.In the scheme of optimizing, also be in series with solenoid directional control valve 7 with flow control valve 9 on the described way to cycle oil.Oil pump 3 is also parallelly connected with a skimmer circuit, and skimmer circuit is provided with an overflow valve 5.
