Abstract
The utility model discloses a manual hydraulic nut cutter. The device comprises a manual hydraulic pump, a high-pressure oil pipe and a nut cutter, wherein oil pipe connectors are arranged on the manual hydraulic pump and the nut cutter, the two ends of the high-pressure oil pipe are respectively connected with the manual hydraulic pump and the nut cutter through the oil pipe connectors, a nut socket is arranged at the end part of the nut cutter, a piston is arranged in the nut cutter, a cutting knife is arranged on the piston, the cutting head of the cutting knife is directed at the nut socket, and an oil filling plug, an unloading valve, a pressure gauge and a handle are arranged on the manual hydraulic pump. The device can be conveniently assembled and disassembled and is convenient to carry. The size of the nut cutter is small so that cutting work can be finished in a small space. The cutting knife of the nut cutter is pushed by power which is provided by the manual hydraulic pump to cut off a nut, less force is required by the manual hydraulic nut cutter than a calipers type cutter, and the manual hydraulic nut cutter has cutting force of a higher limit.
Description
Technical field
The utility model relates to a kind of nut breaking cutter, refers more particularly to a kind of hand hydraulic nut breaking cutter.
Background technology
In industrial production widely used nut in the open, in high temperature or corrosive atmosphere, some meetings are by corrosion, have because overload is pulled and threaded off, what also have is touched and screw thread is impaired owing to pounding, occur after similar the problems referred to above, it is very difficult dismantling nut, way is in the past to utilize (gas) weldering that nuts and bolt is sliced off simultaneously, yet in some special industrial and mineral environment, strictly forbid employing fire (electricity) weldering operation, as the Pulverized Coal Bin in power plant, oil-piping high pressure, high temperature conduit etc., locate, change nut bolt and just more allow people feel simply helpless; Recently there is the broken cutter of a kind of pressing tongs formula to cut near artificial mechanism is broken, but run into, need to break more greatly shear force and could break the nut of cutting, because manpower is limited, be difficult to, and the volume and weight of this device is not suitable for some narrow spaces.
Summary of the invention
The technical problems to be solved in the utility model be to provide a kind of easy to use, adapt to all kinds of operating modes and the nut breaking cutter lower to manpower requirement.
In order to solve the problems of the technologies described above, the utility model provides a kind of hand hydraulic nut breaking cutter, by hydraulic hand-pump, high-pressure oil pipe and nut breaking cutter, formed, described hydraulic hand-pump and nut breaking cutter are provided with tubing interface, and described high-pressure oil pipe two ends are connected with nut breaking cutter with hydraulic hand-pump respectively by tubing interface.
As further improvement of the utility model, described nut breaking cutter end is provided with nut running-on, is provided with piston in nut breaking cutter, and described piston is provided with brokenly cutting knife, and the cutter head of described broken cutting knife points to nut running-on.
As further improvement of the utility model, described hydraulic hand-pump is provided with oil filler plug, unloader, Pressure gauge and handle.
Adopt said structure, its beneficial effect is: described hand hydraulic nut breaking cutter is comprised of hydraulic hand-pump, high-pressure oil pipe and nut breaking cutter three parts, can easy assembly and disassembly, be easy to carry, nut breaking cutter small volume, can complete brokenly cut at narrow space and do; Utilize hydraulic hand-pump that power is provided, the broken cutting knife that promotes nut breaking cutter cuts off nut, more laborsaving compared with the broken cutter of pressing tongs formula, and possesses the broken shear force of the higher upper limit; Nut running-on can entangle nut securely, prevents slippage; Pressure gauge on hydraulic hand-pump is monitor force size in real time, prevents excess load use.
Accompanying drawing explanation
Fig. 1 is the structural representation of hand hydraulic nut breaking cutter of the present utility model.
In figure: 1-hydraulic hand-pump, 2-high-pressure oil pipe, 3-nut breaking cutter, 4-tubing interface, 5-nut running-on, 6-piston, 7-breaks cutting knife, 8-oil filler plug, 9-unloader, 10-Pressure gauge, 11-handle.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in more detail.
As shown in Figure 1, a kind of hand hydraulic nut breaking cutter, this device is by hydraulic hand-pump 1, high-pressure oil pipe 2 and nut breaking cutter 3 form, described hydraulic hand-pump 1 and nut breaking cutter 3 are provided with tubing interface 4, described high-pressure oil pipe 2 two ends are connected with nut breaking cutter 3 with hydraulic hand-pump 1 respectively by tubing interface 4, described nut breaking cutter 3 ends are provided with nut running-on 5, in nut breaking cutter 3, be provided with piston 6, described piston 6 is provided with brokenly cutting knife 7, the cutter head of described broken cutting knife 7 points to nut running-on 5, described hydraulic hand-pump 1 is provided with oil filler plug 8, unloader 9, Pressure gauge 10 and handle 11.
During use, first open the oil filler plug 8 of hydraulic hand-pump 1, fill with 10# transformer oil or 32# antiwear hydraulic oil, close unloader 9, Pressure gauge 10 is resetted and check whether Pressure gauge 10 normally shows reading; The tubing interface 4 of high-pressure oil pipe 2 one end and hydraulic hand-pump 1 is tightened, the tubing interface 4 of high-pressure oil pipe 2 other ends and nut breaking cutter 3 is tightened; After preparation completes, nut running-on 5 is enclosed within on nut to be cut off, and ajusts and set level, press handle 11, cutting knife 7 is stretched out and be advanced into nut, when broken cutting knife 7 enters nut 1/2, care should be used to presses at a slow speed handle 11, in order to avoid broken cutting knife 7 advances too fast cut wound bolt screw thread, to hear after fracture sound, nut completes brokenly cuts, stop pressing handle 11, open unloader 9, broken cutting knife 7 is return original position, and work completes.
Within the similar designed nut breaking cutter of technical characterictic of any employing and the utility model will fall into protection domain of the present utility model.
