The utility model can simultaneously shear thin steel plates, steel reinforcement and steel strips; the utility model has the advantages of small size, labor saving for use and convenient carrying, providing convenience for workers doing iron works, and reducing the investment of tools.

Description

Light dual-purpose the cutting of ironworker

Technical field:

The utility model relates to a kind of hand-operated tools, and is especially a kind of in order to sheet iron is cut off light dual-purpose the cutting of the ironworker that reinforcing bar, steel bar are cut off.

Background technology:

Iron, welder often all can run into cut off sheet iron, cut off reinforcing bar, the operation of steel bar etc., always needed two kinds of instruments in the past, give work and carry and bring a lot of inconvenience.

Summary of the invention:

The purpose of this utility model provides that a kind of handle is cut iron plate and shear-steel muscle function is integrated, and volume is little, portably uses light dual-purpose the cutting of ironworker easily.

The technical scheme that the utility model adopted is: underframe is made T-shaped, and tool rest is made turnably, reaches to reduce the applicable again purpose of volume.The shear cutter with cut muscle cutter branch front and rear direction with being contained on the tool rest, the two is with a handle, and the supporting point of handle is made the pinch roller formula, adopts second lever to reach laborsaving suitable.Architectural feature is: be welded into T-shaped underframe with channel-section steel, with the rotatable tool rest of pin bolt cross-under, vertical welding two back-up blocks on tool rest, back-up block is clamped the moving knife piece that the top has U-lag, on be inserted in pinch roller, with wheel pressing shaft cross-under working handle; Vertical edge dress shear bottom knife at tool rest becomes the scissors shape with the shear cutter of moving knife piece; Load onto bottom knife that blade and left back-up block inlay constitutes disconnected muscle and cuts at the nearly fulcrum of moving knife piece place.

The utility model has the function of cutting sheet metal, shear-steel concrete steel bar simultaneously, and volume is little, uses laborsavingly, carries lightly, provides convenience for the workman be engaged in ironworker's operation, has reduced the instrument investment.

Description of drawings:

Elaborate below in conjunction with accompanying drawing.

Fig. 1 is the utility model unitary side view.

Fig. 2 is the A-A view of Fig. 1.

The specific embodiment:

The utility model by: but T-shaped underframe 1, T-shaped rotary disk basement 2, disconnected muscle bottom knife 3, pin bolt 4, adjustable top muscle double-screw bolt 5, stud pin 6, left back-up block 7, wheel pressing shaft 8, working handle 9, pressure wheel 10, moving knife piece U-lag 11 moving knife pieces 12, right back-up block 13, disconnected muscle cutter 14, shear cutter 15, shear bottom knife 16, pin bolt 17, band handle nut 18 etc. are formed.

Be welded into T-shaped underframe 1 with channel-section steel, open an axis hole in T-shaped underframe planar central.Tool rest is also made T-shaped rotating disc type 2, make central shaft hole, seat is used pin bolt 17 cross-under on T-shaped underframe 1, with 18 lockings of band handle nut, left back-up block 7 at the bent angle of tool rest 2 horizontal roots of side vertical joint weldering adds 13 one-tenth clamping plate shapes of a right back-up block of weldering again, and the upper end connects working handle 9 with stud pin 6, the supporting point of handle penetrates wheel pressing shaft 8, the pressure wheel 10 of packing into.The moving knife piece 12 of packing in the centre of two back-up blocks, the top of moving knife piece 12 has U-lag 11, entangles pinch roller 10.Penetrate pin bolt 4 at the branched shaft hole relative again with back-up block.T-shaped vertical edge at rotating disk tool rest 2 is loaded onto shear bottom knife 16, with 15 one-tenth scissors shapes of shear upper slitter of moving knife piece 12.At the disconnected muscle cutter cutter 14 of the nearly fulcrum of moving knife piece place dress pincers, cut with 3 one-tenth disconnected muscle of disconnected muscle cutter bottom knife of left back-up block panel.The top muscle double-screw bolt 5 that above the disconnected muscle bottom knife 3 of left back-up block, is welded adjustable again.Operation principle:

In the time will cutting off reinforcing bar, steel bar, working handle 9 is lifted, disconnected muscle is cut and is opened, and puts reinforcing bar into, regulates top muscle double-screw bolt 5 and withstands reinforcing bar, depresses handle, through pinch roller 10 pressure is passed to the moving knife piece and forms second lever, cuts the muscle cutter and becomes to cut off gesture.

In the time will cutting sheet iron, unclamp T-shaped underframe band handle nut 18, the shear swivel is crossed the perpendicular direction of underframe T-shaped, the set lever nut, plate fixed handle difference can folding shear cutter.Because the root of back-up block 7,13 becomes bent horn shape, the limit of cutting off of thin plate can be by the end of back-up block, and cuts off length arbitrarily.

Claims (1)

1, light dual-purpose the cutting of a kind of ironworker, comprise underframe, rotatable tool rest, reach blade, it is characterized in that: be welded into T-shaped underframe (1) with channel-section steel, with the rotatable tool rest (2) of pin bolt (17) cross-under, go up vertical welding two back-up blocks (7), (13) at tool rest (2), back-up block is clamped the moving knife piece (12) that the top has U-lag (11), on be inserted in pinch roller (10), with wheel pressing shaft (8) cross-under working handle (9); Vertical edge dress shear bottom knife (16) at tool rest (2) becomes the scissors shape with the shear cutter (15) of moving knife piece (12); Load onto blade (14) cuts with the disconnected muscle of bottom knife (3) formation that left back-up block is inlayed at the nearly fulcrum of moving knife piece place.
