Technical field
The utility model relates to hand-hydraulic safety cutter, is mainly used in reinforcing bar, round-link chain etc. is sheared.
Technical background
At present, China is in industrialization and urbanization fast-developing period, and construction industry development is very swift and violent, become one of important industry of Chinese national economy, and ferrous materials is the material of main part of building structure all the time, and steel demand for building is bigger, accounts for 50.5% of steel consumption amount.Because it is main material that the infrastructure of China remains with armored concrete, so reinforcing bar and wire rod consumption figure maximum in construction(al)steel always for many years.When the reinforcing bar to diameter 16-25mm blocked, method was more single, and efficient is lower.
In mining equiment, scratch board conveyor is the Transport Machinery that mainly transport the down-hole, and its haulage gear is an annular chains, and along with increasing substantially of scraper plate machine transport capacity, the requirement of strength of round-link chain increases, and the diameter of bar also obviously increases.When haulage chain length is accepted or rejected, block (round-link chain need cut 2 times) to round-link chain, mainly adopt the disconnected method of artificial hard iron in the down-hole, that have even adopt iron hammer to knock or the mode of gas cutting is blocked, labour intensity is big, and efficient is low, brings very big unsafe factor.
In addition, in plant equipment such as cement elevator, electric power dragveyer, sand-digging machine, annular chains also is main power transmission mechanism, uses comparatively extensively, and blocking of its round-link chain needs manpower and apparatus equally.
To sum up narrate, shearing for reinforcing bar, round-link chain becomes a link that influences labor safety, labour intensity and operating efficiency, at present clipper on the market can only be sheared fine steel rib, thin chain link, and complex structure, volume big, carry inconvenience, safety coefficient is low.
Summary of the invention
The utility model is at the existing in prior technology shortcoming, provides that a kind of hand-hydraulic safety cutter is used for reinforcing bar, round-link chain is cut off, and simple in structure, safe and reliable, labour intensity is little, and efficient is higher, and is easy to operate.
The utility model is realized by following technical measures: shear at hollow hand lever formula hydraulic pump is installed on the frame, hand-operated direction valve, pressurized cylinder, plunger case, immovable support, movable carriage and fuel tank constitute clipper, the right chamber of pressurized cylinder is communicated with plunger case, the plunger of plunger case stretches into hollow and shears frame, connect movable carriage on the plunger of plunger case, movable cutter is installed on the movable carriage, the cylinder body of pressurized cylinder installs and fixes knife rest, install and fix cutter on the immovable support, movable cutter and fixed cutting tool position relative engagement, oil pipe on the fuel tank is through manual lever hydraulic pump, hand-operated direction valve is communicated with the left chamber of pressurized cylinder, and the right chamber of pressurized cylinder is communicated with fuel tank through oil pipe.
Wherein, the oil pipe on the fuel tank is installed safety valve through the left chamber of manual lever hydraulic pump, hand-operated direction valve connection pressurized cylinder on this oil pipe.
Wherein, the right chamber of pressurized cylinder is communicated with fuel tank through oil pipe, on this oil pipe check valve is installed.
Before the use, select suitable movable cutter and fixed cutting tool to be installed in respectively on movable carriage, the immovable support, cutting object is put into square shape shear frame, cover protective cover; During shearing, hand-operated direction valve is got to oil-feed position, position, a left side, move back and forth the handle of hand lever formula hydraulic pump, hydraulic oil enters chamber, a pressurized cylinder left side toward pressurized cylinder left side chamber fluid injection, and the big valve piston that promotes pressurized cylinder moves to right, the fluid in the right chamber of pressurized cylinder enters in the plunger case, under the effect of hydraulic coupling, the plunger of plunger case is overhanging, promotes movable cutter, under the acting in conjunction of movable cutter and fixed cutting tool shearing force, material is cut off; After material is cut off, again hand-operated direction valve is got to oil return position, right position, move back and forth the handle of hand lever formula hydraulic pump, hydraulic oil enters the right chamber of pressurized cylinder, under action of hydraulic force, the withdrawal of the plunger of plunger case, movable carriage unclamps withdrawing, simultaneously, pressurized cylinder right-hand member plunger shaft fluid passes back into fuel tank; If round-link chain takes off protective cover, the upset round-link chain is put into the edge of a knife to the opposite side of chain link, covers protective cover, repeats above-mentioned action.
The beneficial effects of the utility model are: 1, simple in structure, easy to operate, practical; 2, hand lever formula hydraulic pump provides hydraulic power, and the fluid direction of pressurized cylinder is supplied with in hand-operated direction valve control, hydraulic booster, and the production efficiency height, labour intensity is low; 3, add a cover protective cover, can not produce the phenomenon of bursting apart, the safety coefficient height; 4, manual operations is easy to control, can not produce spark.
