Description
Technical field
The utility model is related to building machinery technical field, more particularly to a kind of bar cropper.
Background technology
Existing bar cropper generally using electronic cut-out and hand off two ways, is cut off when using electric reinforced bar
It during machine, not only needs to draw temporarily at the scene and buries electric wire, powers on, but also ear-piercing noise is sent out during cutting machine work, not only
Power consumption is big, and wear rate is high, while also constitutes a threat to personal safety and health, in addition, when work-yard does not have power supply, electricity
Dynamic cutting machine can not work normally.Existing hand off tool is generally using hand vice, but hand vice are only suitable for cutting off thinner steel
Muscle, and it is time-consuming, laborious, so as to limit its use scope.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of bar croppers simple in structure.
Technical solution is used by the utility model solves its technical problem：Bar cropper, including rack；The machine
The side of frame is provided with the driving gear and driven gear of mutual external toothing；Its radial direction of the tooth top upper edge of the driven gear
It is provided with knife bar；Cutting blade is provided on the knife bar；It is provided in the rack and the matched ledger-plate of the cutting blade；
The cutting edge of the cutting blade is rectilinear form, and the cutting edge of the ledger-plate is circular shape；The driving gear tooth top upper edge its
Radial direction is provided with handle.
Further, the inner end of the knife bar is the arc structure being adapted with the outside circle of the driven gear, the knife
The inner end of bar is provided with the protrusion being adapted with the tooth socket of the driven gear.
Further, the diameter of the driving gear is more than the diameter of the driven gear.
Further, the length of the handle is more than the sum of the diameter of the driving gear and the diameter of the driven gear.
Further, the end set of the handle has anti-skid sleeve.
The beneficial effects of the utility model are：The bar cropper of the utility model, it is simple in structure, it can be light without power supply
Pine cut-out reinforcing bar, and noise-less pollution, it is not only safe but also easy to operate.In use, need to only apply active force on handle, lead to
It crosses driving gear and drives driven gear rotation, so that it may reinforcing bar be cut off by cutting blade and ledger-plate.
Description of the drawings
Fig. 1 is the structure diagram of the bar cropper of the utility model；
Reference numeral is in figure：1- racks, 2- driving gears, 3- driven gears, 4- knife bars, 5- cutting blades, 6- ledger-plates,
7- handles, 8- protrusions, 9- anti-skid sleeves.
Specific embodiment
The utility model is described further with reference to the accompanying drawings and examples：
As shown in Figure 1, bar cropper described in the utility model, including rack 1；The side of the rack 1 is provided with
The mutual driving gear 2 of external toothing and driven gear 3；Its radial direction of the tooth top upper edge of the driven gear 3 is provided with knife bar
4；Cutting blade 5 is provided on the knife bar 4；It is provided in the rack 1 and the 5 matched ledger-plate 6 of cutting blade；It is described
The cutting edge of cutting blade 5 is rectilinear form, and the cutting edge of the ledger-plate 6 is circular shape；2 tooth top upper edge its diameter of the driving gear
Direction is provided with handle 7.
In Fig. 1, the cutting blade 5 is arranged on the bottom of knife bar 4 and close to the position of rack 1, the cutting blade 5 and knife
Bar 4 can be integrally formed as preferred embodiment, and the cutting blade 5 is detachably connected on knife bar 4, convenient to overhaul and replacement.
The ledger-plate 6 is detachably connected in rack 1.In use, reinforcing bar is placed on ledger-plate 6, the application effect on handle 7
Power, handle 7 drive driving gear 2 to rotate, and then driven gear 3 is driven to rotate synchronously, and knife bar 4 is rotated with driven gear 3,
Cutting blade 5 is promoted to be docked with the ledger-plate 6 being arranged in rack 1, shearing force is formed to reinforcing bar, and then cut reinforcing bar.Passing through will
The cutting edge of ledger-plate 6 is set as circular shape, when reinforcing bar is placed on ledger-plate 6, not only increases ledger-plate 6 and reinforcing bar
Contact area, and can prevent reinforcing bar from moving, further improve stability during bar cutting.
To make knife bar 4 and 3 stable connection of driven gear, processing simple, the inner end of the knife bar 4 be with it is described driven
The arc structure that 3 outside circle of gear is adapted, the inner end of the knife bar 4 is provided with to be adapted with the tooth socket of the driven gear 3
Protrusion 8.The inner end of the knife bar 4 refers to that one end being connect with the driven gear 3.The inner end of the knife bar 4 need to only add
The arc structure that work is adapted into the outside circle with the driven gear 3, processing are simple.The shape of the protrusion 8 and institute
The shape for stating the tooth socket of driven gear 3 is adapted.The protrusion 8 is welded in the tooth socket of the driven gear 3, the knife bar 4
Tooth top of the inner end respectively with the protrusion 8 and driven gear 3 be welded and fixed.The parts machining of the connection structure is simple, even
Connect stabilization.
To increase the shearing force of bar cropper, the diameter of the driving gear 2 is more than the diameter of the driven gear 3,
In rotational handle 7, the angular speed of the driving gear 2 is more than the angular speed of the driven gear 3, increases the knife bar 4
Angular speed during rotation so as to increase shearing force when cutting blade 5 coordinates with ledger-plate 6, makes reinforcing bar be easier to be cut off.
The length of the handle 7 is more than the sum of the diameter of the driving gear 2 and the diameter of the driven gear 3.Pass through
Increase the length of handle 7, increase the torque applied on handle 7, reducing cut-out reinforcing bar needs the work being applied on handle 7
Firmly.Further, the end set of the handle 7 has anti-skid sleeve 9.The anti-skid sleeve 9 can be made of plastics or rubber.
