Abstract
The utility model discloses a hydraulic shearing device, which comprises a shear portion and a drive portion. A sheath is arranged between the shear portion and the drive portion, the front end of the sheath is in the shape of a horn mouth, and the root of the shear portion is sleeved by the sheath to prevent accidental injury. A quick connector of the drive portion is connected with a hydraulic source, a hand control valve is driven by turning a handle so that hydraulic oil enters a front cavity or a rear cavity of a cylinder to push a piston to move, cutters are closed or opened by the aid of a connecting rod, and accordingly shearing operation is completed. The hydraulic shearing device is compact in structure, small in size and light in weight, is capable of rotating around the center of a clamp by the design of a lifting handle and a rotating ring so as to facilitate use, and the sheath and colored cover strips thereon serve as a warning prompt mechanism and can decrease the accidental injury to users.
Description
Technical field
The utility model belongs to the hydraulic tool field, relates in particular to a kind of hydraulic pressure cutter.
Background technology
Along with The development in society and economy; Hydraulic pressure cutter with advantages such as shearing force are big, easy to operate is used quite general; Usually and the supporting use of power pump, electrodynamic pump or manual pump; Sheet material, bar and various section bar be can shear, when breaking out of fire, traffic accident, earthquake disaster, metal or nonmetal structure cut; As shear structures such as disconnected reinforcing bar guardrail, doorframe, cable and automobile frame; Can promptly give first aid to the victim or the rescue that are confined in the constrained environment to be in the pest that receives in the hazardous environment, therefore become the indispensable break-in tool of fire-fighting, traffic police team, industrial and mining enterprises and other rescue departments, the size of its shear ability and the comfort level of use are determining the effect of orcible entry.In the existing technology, the handle of carrying of hydraulic pressure cutter is fixed and can not be rotated, and under some occasion, is unfavorable for the effect of the instrument of giving full play to; Cutting off the warning structure that also lacks necessity on the body, operating personnel come to harm when under emergency, using easily.
The utility model content
It is big and the hydraulic pressure cutter of warning mechanism arranged that the purpose of the utility model provides a kind of simple in structure, easy to operate, shear strength.
The technical scheme of the utility model is: the hydraulic pressure cutter comprises hydraulic part and by the scissors part of its driving, also is provided with sheath between the two.Sheath comprises butt end and thin end, and butt end is a bell mouth shape, entangles the root of scissors part, and thin end middle part is connected with carries handle.Drive part comprises that handle, hand control valve, hydraulic cylinder and top are connected with the piston of connector, and hand control valve is positioned at the inside of handle.The thin end of sheath is enclosed within on the hydraulic cylinder, and is gapped between the two.Scissors partly comprises connecting rod, supporter and cutting knife, difference pin joint between the outer end of connecting rod and said connector and cutting knife, and supporter is fixed in an end of hydraulic cylinder, and the inner of cutting knife is connected between two otic placodes of supporter through bolt.
The advantage and the beneficial effect of the utility model are: owing to adopt technique scheme, the volume and weight of hydraulic pressure cutter is little, and the design of carrying handle and rotating ring can be done around the rotation at caliper center the hydraulic pressure cutter, the convenient use; Sheath and on colored cover strip can reduce the unexpected injury that the user receives as alarm and prompt mechanism.

The specific embodiment
As shown in Figure 1, the hydraulic pressure cutter comprises hydraulic part and by the scissors part of its driving, also is provided with sheath 1 between the two.Sheath 1 comprises butt end and thin end, and butt end is a bell mouth shape, entangles the root of scissors part, and what thin end middle part was connected with the shaped form profile carries handle 2.Drive part comprises that handle 4, hand control valve 5, hydraulic cylinder 6 and top are connected with the piston 7 of connector 8, and hand control valve 5 is positioned at the inside of handle 4.The thin end of sheath 1 is enclosed within on the hydraulic cylinder 6, and is gapped between the two.Scissors partly comprises connecting rod 9, supporter 10 and cutting knife 11, difference pin joint between the outer end of connecting rod 9 and said connector 8 and cutting knife 11, and supporter 10 is fixed in an end of hydraulic cylinder 6, and the inner of cutting knife 11 is connected between two otic placodes of supporter 10 through bolt.Chromatic colour cover strip on the sheath 1, as preferred embodiment a kind of, color is chosen as yellow.The thin end place of keeping to the side of sheath 1 is provided with the rotating ring 3 of thin tubular, and gapped between the sheath 1.
The course of work of this instance: utilize the fluid pressure transmission to equate that principle produces external force output to the piston oiling; Hydraulic oil gets into from fast interface along oil pipe the hydraulic cylinder 6, and the hand control valve 5 of turning handle 4 drive its internal portions makes hydraulic oil get into the back cavity of hydraulic cylinder 6; Promoting piston 7 outwards moves; The connecting rod 9 of pin joint on connector 8 stretches laterally, makes cutting knife 11 do the rotation around bolt, thereby accomplishes snap-action.Linkage converts the reciprocating force of piston 7 and connector 8 into the shear strength of cutting knife 11.After the snap-action, the hand control valve 5 of turning handle 4 drive its internal portions makes hydraulic oil get into the ante-chamber of hydraulic cylinder 6, promotes piston 7 and inwardly moves, and connector 8 drivening rods 9 inwardly shrink, thereby cutting knife 11 opens.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
