Description

Universal shearing cutter

Technical field

The utility model belongs to rescue and relief work equipment technical field, is specifically related to a kind of Universal shearing cutter.

Background technology

Along with the fast development of Chinese national economy and urban construction, various natural calamities, serious accident happen occasionally, and the people's lives and property is subject to serious threat.For this reason, aspect the research of rescue and relief work instrument, all doing a large amount of work both at home and abroad, develop into modern pneumatic tool, hydraulic tool, ultrahigh-pressure hydraulic instrument from initial hand tools, kind, the function of product also become better and approaching perfection day by day, but existing clipper complex structure is bulky, and cutter head angle is fixed, in small space, cannot shear, therefore be necessary to propose to improve.

Utility model content

The technical problem that the utility model solves: a kind of Universal shearing cutter is provided, shear knife can be swung around hydraulic cylinder in ± 90 degree scopes, efficiently solve the clipper of some small space routines because volume is large, the fixing problem that cannot shear of shear knife angle, improved the ability of rescue personnel's rescue and relief work.

The technical solution adopted in the utility model: Universal shearing cutter, there is cylinder body, described cylinder body one end inner chamber is fixedly connected with cylinder cap, the piston rod that is positioned at cylinder body from the cylinder body other end stretch out and piston rod head and shear knife I rear end hinged, the locating hole matched in clearance of rotary hinged seating one end and cylinder cap end is also spacing with dog screw, the described rotary hinged seating other end and shear knife II rear end are hinged, the hinged formation sheared edge of described shear knife II and shear knife I middle part, described cylinder body sidepiece is shaped with C oilhole and D oilhole and respectively with to be fixed on A oilhole and B oilhole on the handle of cylinder body sidepiece corresponding.

Further, described shear knife II and shear knife I rear end are all shaped with U-shaped groove, and described rotary hinged seating end and piston rod head all insert in U-shaped groove and fix with bearing pin.

Further, described rotary hinged seating and locating hole abutting end are shaped with cannelure, and described dog screw is pushed against cannelure through cylinder cap sidepiece) in.

The utility model is structure optimization compared with prior art, and volume is little, lightweight, shear knife can rotate take piston rod as axle within the scope of ± 90 °, facilitate the arbitrarily angled shearing of small space, instrument uses more flexible, has improved greatly the operating efficiency of rescue.

The specific embodiment

Below in conjunction with accompanying drawing 1-4, a kind of embodiment of the present utility model is described.

Universal shearing cutter, there is cylinder body 4, described cylinder body 4 one end inner chambers are fixedly connected with cylinder cap 2, the piston rod 3 that is positioned at cylinder body 4 from cylinder body 4 other ends stretch out and piston rod 3 heads and shear knife I 8 rear ends hinged, locating hole 9 matched in clearance of rotary hinged seating 5 one end and cylinder cap 2 ends are also spacing with dog screw 6, specifically, described rotary hinged seating 5 is shaped with cannelure 11 with locating hole 9 abutting ends, and described dog screw 6 is pushed against in cannelure 11 through cylinder cap 2 sidepieces.Described rotary hinged seating 5 other ends and shear knife II 1 rear end are hinged, described shear knife II 1 and the shear knife I 8 hinged formation sheared edges 10 in middle part, specifically, described shear knife II 1 and shear knife I 8 rear ends are all shaped with U-shaped groove 12, and described rotary hinged seating 5 ends and piston rod 3 heads all insert in U-shaped groove 12 and use bearing pin 13 fixing.Described cylinder body 4 sidepieces are shaped with C oilhole and D oilhole and respectively with to be fixed on A oilhole and B oilhole on the handle 7 of cylinder body 4 sidepieces corresponding.

Operation principle: the C oilhole that the A oilhole of hydraulic oil on handle 7 enters cylinder body 4 is in plunger shaft, promote piston rod 3 protruding, the shear knife I 8 reach drive shear knife I 8 that are fixed on piston rod front end are rotated take bearing pin 13 as fulcrum, the also rotation take bearing pin 13 as fulcrum of shear knife II 1, two shear knives make sheared edge 15 closures take the bearing pin of its middle part pin joint as fulcrum rotates, and complete shearing work.The B oilhole that the hydraulic oil of piston rod chamber flows to handle 7 through D oilhole flows out, and completes shearing function one time.When hydraulic oil arrives rod end chamber from the oil-feed of B oilhole through D oilhole, piston rod 3 is retracted and is driven two shear knives oppositely to open, and realizes the planning function, and the oil of plunger shaft flows out to handle 7 from A oilhole through C oilhole, completes one action circulation.

The utility model adopts 63MPa ultrahigh-pressure hydraulic technology, the technical state-of-the-art technology of gathering the subjects such as machinery, hydraulic pressure, material, heat treatment, described shear knife adopts high strength alloy steel forging, process special thermal treatment, and shear knife all can carry in whole length range.

The utility model is compared traditional hydraulic clipper, structure optimization, and volume is little, lightweight, cutter head can piston rod be that axle rotates within the scope of ± 90 °, facilitates the arbitrarily angled shearing of small space, instrument uses more flexible, has improved greatly the operating efficiency of rescue; Supplementing conventional hydraulic rescue tool, support the use with power pump or manual pump, be mainly used in rescue site limited space, cannot use the occasion of conventional hydraulic tool, utilize that its volume is little, shear knife can be at 180 degree scope flexible rotatings, complete shearing work, rescue is confined in the victim in constrained environment or rescues the pest that is subject in hazardous environment, reaches the object of rescue or the disaster relief.

Above-described embodiment, is preferred embodiment of the present utility model, is not used for limiting the utility model practical range, and the equivalence of being done with content described in the utility model claim therefore all changes, within all should being included in the utility model claim scope.
