Abstract

The utility model relates to a hand concrete iron cut-out machine which overcomes the defects that the existing hand wire cutting clamp wastes labor and the range of cutting is small. A fan-shaped gear plate and a gear with a handle which are engaged with each other by shafts are arranged on a frame. A fan core axle on the fan-shaped gear plate is provided with a movable blade corresponding to a fixed blade arranged on the frame, and a groove for putting reinforcing steel bars is arranged between the two blades on the frame. The utility model has the advantages of simple structure, easy use and labor saving, big cutting range, no electricity used and durability, and the utility model is suitable for the occasions, such building industry and other places which need to cut the reinforcing steel bars.

Description

Manual bar cropper

The utility model relates to a kind of manual bar cropper of cutting reinforcing bar.

At present, what people generally used when shear reinforcement is " section bar machine ", and promptly electric rebar cutter and wiring clip claim bolt clipper again, and these the two kinds instruments that cut off reinforcing bar are not ideal.The power consumption of section bar machine is big, and the wearing and tearing of grinding wheel are also more serious, and often will change, its price height, and the loss of steel is also high, and in use, safety coefficient is little, and service life is short.And bolt clipper generally only is applicable to the scope of cutting off 6mm to 10mm, is the long bolt clipper of 700cm as handle, and with the masterpiece time spent of 40Kg, edge of a knife shearing pressure has only about 2 tons, and it has limited the shearing scope.

The purpose of this utility model is to provide a kind of shearing scope big, uses the manual bar cropper in labour-saving.

The utility model is finished with following mode: manually bar cropper is by install sector wheel plate 5 and 8 engagements of band handle gear respectively with axle 4 and axle 9 on frame 6, fan axle place installing cutting blade 3 on sector wheel plate 5, installing fixed blade 1 corresponding cutting blade 3 on frame 6.Sector wheel plate 5 and band handle gear 8 are in the groove that is installed on the frame 6, on the frame 6 between fixed blade 1 and the cutting blade 3 fluted 10.

The manual bar cropper of the utility model, be to adopt band handle gear drive sector gear plate, drive the structure of cutting blade shear reinforcement, it has utilized suitable speed ratio to increase the effect of transmission power, and the length and the suitable length that strengthens the afterburning sleeve of the arm of force of dwindling the salty arm of scissors, reach laborsaving, simultaneously, it is safe in utilization that it has the electricity consumption of need not, and no feed consumption, cost are low, durable in use, can be widely used in building trade and other places.

Fig. 2 is the utility model vertical view

Below in conjunction with accompanying drawing the utility model is described in further detail:

As shown in Figure 1 and Figure 2, the manual bar cropper of the utility model is by sector wheel plate 5 and 8 engagements of band handle gear are housed in the groove in the middle of the frame 6, sector wheel plate 5 usefulness axle 4 is contained on the frame 6, on the sector wheel plate 5 above the axle 4, cutting blade 3 is housed, it is corresponding with cutting blade 3 with bolt 2 fixed blade 1 to be housed on frame 6, have groove 10 on the frame 6 between fixed blade 1 and the cutting blade 3, be convenient to place the reinforcing bar location, band handle gear 8 usefulness axle 9 is contained on the frame 6.During use, the reinforcing bar that will cut is positioned in the groove 10, with the hands holding afterburning sleeve 7 entangles band handle gear 8 and presses down clockwise, by of the engagement of band handle gear 8 with sector rack 5, thereby drive sector wheel plate 5 and do the counterclockwise rotation around axle 4, as shown in Figure 1, by the movable blades on the sector wheel plate 53, pressure is reached on reinforcing bar and the fixed blade 1, until with bar cutting.

The utility model as be designed to the edge of a knife to distance of shaft centers from for 40mm, on the afterburning sleeve secondary sleeve pipe complete set, its tail end to axle center length is 1400mm, gear ratio is 1: 5 o'clock, if the 40Kg pressure effect of user's both hands, the shear pressure of the edge of a knife can reach 7 tons, can cut off the reinforcing bar of φ 18mm--φ 20mm, general between twenty and fifty male citizen's body weight a lot of about 60 kilograms operate these facility with 40 kilograms of downforce and should most of people can be competent at.
