The upper end cover, the cylinder barrel and the lower end cover are connected by the pull rod and are fixed by the locking nuts, the piston rod passes through the upper end cover and is arranged in the cylinder barrel; the stop iron and the piston rod are screwed and locked by the locking nuts; the piston rod, the upper end cover and the cylinder barrel are in sliding fit and the piston rod is provided with the sealing members; the cylinder barrel, the upper end cover and the lower end cover are in transition fit and the cylinder barrel is provided with the sealing member; the upper end cover is provided with an oil hole communicated with an oil outlet of the change valve, the check valve is connected in parallel with the adjustable restrictor valve, an oil outlet of the check valve is communicated with an oil hole on the lower end cover, and an oil inlet is communicated with the other oil outlet of the change valve. The invention can be automatically and accurately positioned through a hydraulic system without manual adjustment, saves time and labor, and improves the working efficiency.
Description
Technical field
The present invention relates to the guillotine of light industry processing sheet flexible material, the guillotine of hemisection function is especially arranged.
Background technology
Guillotine generally is to realize the accurate hemisection of material is processed by pressure sensor and block iron mechanism; at present; its block iron mechanism all is to adopt worm and gear or feed screw nut's manual adjustment mode; reasons such as strain owing to machining accuracy and processed factory material; when tool setting, often need the repeated multiple times calibration; sometimes even want just can find the tram behind the trial cut; this brings a lot of inconvenience to production; all need tool setting again after tool changing mould or the cutting die wearing and tearing; and product upgrades very fast now; output is also very big, and the tool setting process that takes time and effort is more and more denounced by enterprise.
Summary of the invention
The present invention seeks to overcome the deficiency of existing guillotine block iron mechanism, a kind of conveniently hydraulic pressure block iron mechanism is provided.
Technical scheme of the present invention: contain buting iron, upper end cover, locking nut, piston rod, bottom end cover, pull bar, hold-down nut, cylinder barrel and seal, also contain reversal valve, check valve, adjustable throttling etc., upper end cover, cylinder barrel and bottom end cover are connected by pull bar and fix with hold-down nut, piston rod passes upper end cover and places in the cylinder barrel, and buting iron and piston rod thread connect and locked by locking nut.
Between piston rod and upper end cover, the cylinder barrel for being slidingly matched and being provided with seal.
Be interference fits and be provided with seal between cylinder barrel and upper end cover, the bottom end cover.
Have hydraulic fluid port to be communicated with an oil-out of reversal valve on the upper end cover, check valve and adjustable throttling are connected in parallel, and the hydraulic fluid port on its oil-out and the bottom end cover is communicated with, and another oil-out of oil-in and reversal valve is communicated with.
The invention has the beneficial effects as follows: accurately locate automatically by hydraulic system, need not manual adjustment, time saving and energy saving, improved operating efficiency.
Description of drawings
Accompanying drawing 1 is the structural representation of the embodiment of the invention.
Accompanying drawing 2 is the hydraulic schematic diagram of the embodiment of the invention.
Among Fig. 1: the 1---buting iron; The 2---locking nut; The 3---piston rod; The 4---acorn nut; The 5---Y RunddichtringO; The 6---upper end cover; The 7---O RunddichtringO; The 8---cylinder barrel; 9---piston y-type seal ring; The 10---pull bar; The 11---O RunddichtringO; The 12---bottom end cover.
Among Fig. 2: the 13---check valve; The 14---adjustable throttling; 15---electricity hydraulic control three position four-way directional control valve.
The specific embodiment:
The present invention is further described below in conjunction with drawings and Examples.
In Fig. 1, upper end cover 6, cylinder barrel 8, bottom end cover 12 is connected by pull bar 10, pull bar 10 lower ends and bottom end cover thread connection, pull bar 10 upper ends are fixing by acorn nut 4 and upper end cover 6, cylinder barrel 8 and upper end cover 6, be respectively arranged with O RunddichtringO 7 and 11 between the bottom end cover 12, seal, piston rod 3 passes upper end cover 6 and is slidingly matched, y-type seal ring 5 is in the groove of upper end cover 6, seal, for being slidingly matched, two pistons y-type seal ring 9 is housed in the groove of piston rod 3 between cylinder barrel 8 and the piston rod 3, play the two way seal effect, buting iron 1 and piston rod 3 thread connection are also used locking nut 2 lockings.Fig. 2 is the hydraulic schematic diagram of present embodiment, during tool setting, close adjustable throttling 14, electricity hydraulic control three position four-way directional control valve 15 lower electromagnets get, pressure oil enters the oilhole of bottom end cover 12 through check valve 13, cylinder barrel 8 cavity of resorption oil-feeds, piston rod 3 moves upward, and stops when buting iron 1 supports to the guillotine cope match-plate pattern, unclamp adjustable throttling 14 this moment, start guillotine tool setting program, the guillotine cope match-plate pattern descends, because cope match-plate pattern pressure is greater than the active force of buting iron 1, buting iron 1 will descend with cope match-plate pattern, when cutting die contacts with backing plate, system pressure raises, envelope position during electric hydraulic control three position four-way directional control valve 15 switches to, cope match-plate pattern returns simultaneously, buting iron 1 has been accurately positioned, closes adjustable throttling 14, and tool setting is finished.Close adjustable throttling 14 when whole process only needs manually to unclamp adjustable throttling 14 and end when beginning and get final product, time saving and energy saving, its location is finished according to cutting die automatically by system, and is accurately reliable.
