Abstract

The utility model relates to a manual hydraulic steel bar cutter. The utility model is characterized in that a manual fuel pump (2) which is communicated with oil cylinder (12) and oil reserving chamber (10) is arranged on a frame (1). A piston is installed in the oil cylinder, and the front end of the piston is fixed on a cutting blade. A fixed blade (19) is fixedly installed on the front frame (1) of the cutting blade. An adjustable stop lever (20) is arranged on one side of the cutting blade. Thus, the utility model has the advantages of portability, convenience, safety, simple structure, convenient operations, etc.

Description

Hand hydraulic steel rod cutter

The utility model relates to the shear that a kind of operation by hand is used for cutting off reinforcing bar, particularly use the shear of hand-hydraulic mode.

Cut off at present reinforcing bar and adopt the sawing machine saw usually, emery wheel is cut, and gas cutting or bolt clipper are cut etc.We know that sawing machine can only carry out in the workshop, can not move easily because the big thing of its body is heavy, more can not carry, and there is certain requirement in its required place; Abrasive machine cutting need be fixedly mounted on the building site of power supply and use, and used grinding wheel consumption is big, and cost is also high, and security is relatively poor; Then need professional skilled worker to be competent at gas cutting, cost is also high; Then can only cut the reinforcing bar of diameter below 10 millimeters as for bolt clipper, narrow application range, labour intensity is big.The purpose of this utility model is in order to overcome the deficiency of above-mentioned existence, to be easy to carry and provide a kind of, and is easy to use, safety and economic hand-hydraulic bar cropping machine.

The purpose of this utility model is finished by following technical solution, support is provided with hand oil pump, this oil pump communicates with oil cylinder and oil storage chamber respectively by sending oily passage and oil inlet passage, drainback passage between oil cylinder and the oil storage chamber is provided with oil return valve, the piston nose that is placed in the oil cylinder and has a return spring is fixed with cutting blade, is fixed with ledger-plate on the support in cutting blade motion the place ahead.

The utility model also is provided with adjustable pin in described support 1 upper cutter one side.

Description of drawings is as follows:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is that A among Fig. 1 is to view.

Below will the utility model is further introduced by accompanying drawing: support 1 be provided with hand oil pump 2, the composition of this hand oil pump 2 is: have a pump housing 3 to be fixed on the support 1, be mounted with the plunger 4 of slippage up and down in the pump housing 3, the top of this plunger 4 is connected with rocking bar 5, the end of rocking bar 5 joins with the pole 6 that is connected on the support 1, respectively be provided with in line check valve 7 and fuel-displaced check valve 8 in the bottom of the pump housing 3, grasping rocking bar 5 moves up and down, plunger 4 also will move up and down thereupon this moment, realize the effect of pump.Above-mentioned hand oil pump 2 communicates with oil storage chamber 10 by oil inlet passage 9, communicates with oil cylinder 12 by sending oily passage 11, and oil storage chamber 10 all is arranged on the support 1 with oil cylinder 12, drainback passage 13 is arranged between the two, and be provided with oil return valve 14.Be mounted with piston 15 in oil cylinder 12, the front end of this piston 15 exposes on workbench and is fixedly connected with cutting blade 18 with screw 17, and fixed in position has ledger-plate 19 on the support in its motion the place ahead.Can fix its position for the reinforcing bar that guarantees to make required cutting is placed on the workbench 16, be unlikely to run-off the straight in cutting process, influence cutting effect, the utility model is mounted with adjustable pin 20 on a side support of cutting blade 18.During use, earlier the reinforcing bar of required cutting is placed on the work top between cutting blade 18 and the ledger-plate 19, adjustment pin 20 makes it paste reinforcing bar and makes reinforcing bar be basically perpendicular to blade (a kind of reinforcing bar of specification only need be adjusted once), move up and down with hand-motion rocking bar 5 then, thereby the plunger 4 that drives in the oil pump 2 is done straight reciprocating motion, be pressed into promotion pistons 15 reaches in the oil cylinder 12 from oil storage chamber 10 interior oil suctions, the cutting blade 18 that is fixed on piston 15 front ends just relatively moves with the ledger-plate 19 that is fixed on the support, together with bar cutting.Open oil return valve 14 then, piston 15 is just return under the effect of return spring 21 and is resetted, and the oil of will working simultaneously pushes back oil storage chamber 10 through drainback passage 13, thereby finishes a work period.

The utility model also can be made said structure split type, promptly according to different needs, oil storage chamber and support are separated setting separately, and connect by high pressure rubber hose, equally also oil pump and support can be separated separately being provided with, connect by high pressure rubber hose too, can not only on ground or platform, use like this, but also available holding sheared the reinforcing bar under the various different conditions in space.On separate type, also can adopt the small-sized electric oil pump to replace hand oil pump.The utility model also is applicable to the cut-out wirerope in addition.

The utility model compared with prior art has easy to carryly, safe and reliable, simple in structure, uses easy to operately, is widely used in the characteristics such as cutting reinforcing bar or wirerope on the building site of shortage equipment and the energy.

Claims

1, a kind of hand-hydraulic bar cropping machine, it is characterized in that support (1) is provided with hand oil pump (2), this oil pump (2) communicates with oil cylinder (12) and oil storage chamber (10) respectively by sending oily passage (11) and oil inlet passage (9), drainback passage (13) between oil cylinder (12) and the oil storage chamber (10) is provided with oil return valve (14), piston (15) front end that is placed in the oil cylinder (12) and has return spring (21) is fixed with cutting blade (18), is fixed with ledger-plate (19) on the support (1) in cutting blade (18) motion the place ahead.

2, hand-hydraulic bar cropping machine as claimed in claim 1 is characterized in that described support (1) upper cutter (18) one sides are provided with adjustable pin (20).
