Abstract
The utility model relates to a kind of hydraulic shear, comprise cutter head, hydraulic cylinder, described cutter head is fixedly connected with between hydraulic cylinder, be characterized in described cutter head is provided with breach, be provided with fixed blade, cutting blade in breach, described fixed blade is fixed on cutter head, and described cutting blade is connected with the plunger of hydraulic cylinder, the control lever of described hydraulic cylinder is connected with fixed handle, and described hydraulic cylinder is fixedly connected with static handle; Be connected by screw between described fixed blade and cutter head; Described fixed handle, static handle are provided with Anti-slip cover; Described hydraulic cylinder is provided with overload protective device; Compared with prior art, the beneficial effects of the utility model are: the utility model provides a kind of hydraulic shear, be characterized in compact structure, can be used for the occasion that Large Shear equipment cannot operate, especially, time operating space is little, the utility model has simple, the practical feature reliably of structure simultaneously.
Description
Technical field
The utility model relates to hydraulic tool field, particularly relates to a kind of hydraulic shear.
Background technology
Powerful hydraulic shear is one of perfect orcible entry rescue tool product, and it adopts up-to-date design and machining, heat treatment and process of surface treatment, and selects high strength steel and aviation high-strength aluminum alloy material, and intensity is high, strength is large, volume is little, lightweight.The mechanics design optimized, unique cutter support tool, provides maximum shearing force, and durable in use; Be applicable to the orcible entry rescue in each place.Hydraulic shear has an aluminum alloy casing usually, and its blade is forged by hot-rolled steel and forms.Piston and piston push rod are then usual to be made up of hot rolled alloy steel.Hydraulic shear is mainly used to shear the material as sheet metal and plastics and so on.Usually, they are used to cut off automobile and other vehicles to save trapped passengers.The same with hydraulic spreader, hydraulic shear also can provide power by gasoline driven device.Different from hydraulic spreader, hydraulic shear is that bending claw-like extends, and its end is pointed.The same with the principle of hydraulic spreader, hydraulic fluid is applied to piston pressure after flowing into hydraulic cylinder.The direction being applied to power on piston is depended in the folding of blade.When piston push rod rises, blade opens.When piston push rod declines, blade starts to object, such as roof, closes up, and it is cut off.
When construction, some are comparatively thick when but cutting mechanics cannot be used again to cut, workman Chang Shougong hacksaw is sawed-off, and not only labour intensity is large, and inefficiency.
Utility model content
The utility model is in order to overcome deficiency of the prior art, provide a kind of hydraulic shear, be characterized in compact structure, can be used for the occasion that Large Shear equipment cannot operate, especially, time operating space is little, the utility model has simple, the practical feature reliably of structure simultaneously.
The utility model is achieved through the following technical solutions:
A kind of hydraulic shear, comprise cutter head, hydraulic cylinder, described cutter head is fixedly connected with between hydraulic cylinder, be characterized in described cutter head is provided with breach, be provided with fixed blade, cutting blade in breach, described fixed blade is fixed on cutter head, and described cutting blade is connected with the plunger of hydraulic cylinder, the control lever of described hydraulic cylinder is connected with fixed handle, and described hydraulic cylinder is fixedly connected with static handle.
As optimal technical scheme of the present utility model, be connected by screw between described fixed blade and cutter head.
As optimal technical scheme of the present utility model, described fixed handle, static handle are provided with Anti-slip cover.
As optimal technical scheme of the present utility model, described hydraulic cylinder is provided with overload protective device.
Compared with prior art, the beneficial effects of the utility model are: the utility model provides a kind of hydraulic shear, be characterized in compact structure, can be used for the occasion that Large Shear equipment cannot operate, especially, time operating space is little, the utility model has simple, the practical feature reliably of structure simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, cutter head; 2, fixed blade; 3, cutting blade; 4, hydraulic cylinder; 5, static handle; 6, Anti-slip cover; 7, fixed handle; 8, control lever.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
Described a kind of hydraulic shear, comprise cutter head 1, hydraulic cylinder 4, described cutter head 1 is fixedly connected with between hydraulic cylinder 4, be characterized in described cutter head 1 is provided with breach, be provided with fixed blade 2, cutting blade 3 in breach, described fixed blade 2 is fixed on cutter head 1, and described cutting blade 3 is connected with the plunger of hydraulic cylinder 4, the control lever 8 of described hydraulic cylinder 4 is connected with fixed handle 7, and described hydraulic cylinder 4 is fixedly connected with static handle 5.
As a preferred embodiment of the present utility model, be connected by screw between described fixed blade 2 and cutter head 1.
As a preferred embodiment of the present utility model, described fixed handle 7, static handle 5 are provided with Anti-slip cover 6.
As a preferred embodiment of the present utility model, described hydraulic cylinder 4 is provided with overload protective device.
Compared with prior art, the beneficial effects of the utility model are: the utility model provides a kind of hydraulic shear, be characterized in compact structure, can be used for the occasion that Large Shear equipment cannot operate, especially, time operating space is little, the utility model has simple, the practical feature reliably of structure simultaneously.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
