Abstract

A portable hydrostatic cutter used in manufacturing, detaching and building industries comprises a working mechanism, a power switch, an oil box, a motor, a spill valve, an oil pump and an oil pipe, and is characterized in that the working mechanism is composed of a cutting tool, a connecting rod, a tool frame, a fastener, an oil pipe, a hydraulic cylinder, a piston, a piston rod connected with the cutting tool via the connecting rod, a change-over valve, a casing body, a handle and a pin roll. The utility model has the simple structure, low cost, convenient and reliable usage, capability of doing underwater operation, employment of electrically hydraulic actuation, strong force of cutting, low working noise, no-pollution of environment, no-spark when working, and no-result of fire hazard, thereby being able to cut various metal shaped materials by changing different knife tools and make mold processing by changing the knife tool into a die.

Description

Portable hydraulic cutter

Technical field.The utility model relates to the portable hydraulic cutter of a kind of cutting machine, particularly cutting circular steel and various metal sections.

Background technique.Now manufacturing, disassemble the cutting of industry, construction industry to various materials, the particularly cutting of metallic material, mostly adopt conventional methods such as shearing machine, sawing machine or grinder processing, the common drawback of this processing method is all to be based on process equipment basically, material to be cut or device are brought up to equipment one by one, and anchor clamps often must be set process, do obviously not only quite inconvenient like this, effort is big and efficient is low, and in fact also is difficult to whole realizations.Application number is that 96224047.8 Chinese patent application " Hydraulic power tools is cut) " has proposed a feasible solution, but because it without electric power, makes it when obtaining not to be subjected to this advantage of power limitations, its cutting power is restricted unavoidably.

Summary of the invention.The purpose of this utility model provides a kind of portable powerful hydraulic cutter that has motor-drive pump can cut various metal sections as power.

The utility model is so to realize: portable hydraulic cutter comprises operation mechanism, power switch, fuel tank, motor, relief valve, oil pump and oil pipe, it is characterized in that piston rod, selector valve, housing, handle and bearing pin that operation mechanism is connected with cutting tool by cutting tool, connecting rod, knives rack, fastening piece, oil pipe, oil hydraulic cylinder, piston, by connecting rod form.

Connecting rod of the present utility model place is provided with a guard shield in order to prevent that foreign material from curling.

According to need of work, cutting tool of the present utility model can be made into and is used for some container is carried out from inside to outside the outside cutter of the cutting edge of disassembling cutting, also can be adapted as the small mould that carries out mold pressing processing.

For ease of adjusting oil pressure, a pressure gauge is housed at the relief valve place.

The utility model is simple in structure, and cost is low, and is easy to use and reliable, can be used for underwater operation, adopt electric hydaulic to drive, cutting force is strong, operational noise is low, unlikely befouling environment, no-spark during work, the unlikely disaster hidden-trouble that causes, as long as use different cutters instead, just can cut various metal sections, the mould that cutter can also be changed the outfit carries out mold pressing processing.

Description of drawings.

Fig. 1 is the utility model system connection diagram.

Fig. 2 is operation mechanism's partial schematic sectional view.

Illustrate: 1 cutting tool, 2 connecting rods, 3 bearing pins, 4 oil hydraulic cylinders, 5 piston rods, 6 pistons, 7 selector valve switch A, 8 selector valves, 9 selector valve switch B, 10 oil pipes, 11 pressure gauges, 12 relief valves, 13 oil pumps, 14 motor, 15 fuel tanks, 16 fastening screws, nut 17 knives racks 18 guard shields 19 housings 20 handles

Mode of execution.As shown in Figure 1, 2, portable hydraulic cutter comprises operation mechanism, power switch, fuel tank 15, motor 14, relief valve 12, oil pump 13 and oil pipe 10, it is characterized in that operation mechanism by cutting tool 1, connecting rod 2, knives rack 17, fastening screw trip bolt nut 16, oil pipe 10, oil hydraulic cylinder 4, piston 6, form by piston rod 5, selector valve 8, housing 19, handle 20 and bearing pin 3 that connecting rod 2 is connected with cutting tool 1.Starting motor 14, oil pump 13 work, before cutting machine work, fluid flows back to fuel tank 15 through selector valve 8, pressing selector valve switch A7, fluid is pressed to oil hydraulic cylinder 4 back cavities through selector valve 8, propelling piston 6, driving cutting tool 1 by connecting rod 2 cuts, after once cutting is finished, i.e. pressing selector valve switch B9, fluid is pressed to oil hydraulic cylinder 4 ante-chambers through selector valve 8, move behind the piston 6, drive cutting tool 1 by connecting rod 2 and be in state to be cut next time, the fluid in oil hydraulic cylinder 4 back cavities then flows back to fuel tank 15 by selector valve 8 at this moment, and vice versa.If oil circuit is obstructed, then fluid returns fuel tank 15 through relief valve 12.
