Specific embodiment
Following is a specific embodiment of the present invention in conjunction with the accompanying drawings, technical scheme of the present invention will be further described,
However, the present invention is not limited to these examples.
As shown in figure 1, figure 2, figure 3, figure 4 and figure 5, a kind of cutter, for shearing the wire rod 600 of steel, by wire rod 600
It is cut into the length of setting, comprising: clutch, feeding mechanism 200, transmission mechanism 300 and cutting mechanism 400, cutter
On be additionally provided with rack, for carrying above-mentioned mechanism, wire rod 600 is coiled in biscuit frame, is then fed machine
Structure 200 involves, and enters on cutting mechanism 400, is cut into one section one section by cutting mechanism 400.
In this cutter, by the way that clutch is arranged, the effect of self-feeding shearing can be realized, in clutch
Under coordination, when feeding mechanism 200, which conveys wire rod 600, arrives predetermined position, clutch stops feeding structure, and starts biography
Motivation structure 300, transmission mechanism 300 are that cutting mechanism 400 transmits power, cut the wire rod 600 of setting length, and in clutch
Under the coordination of structure, feeding mechanism 200 is made to continue feeding, and cutting mechanism 400 is made to stop shearing.
Wherein, clutch includes feeding clutch 110 and shearing clutch 120, when the feeding clutch 110 divides
From when the shearing clutch 120 engage；Feeding clutch 110 and shear clutch 120 effect other than passing movement,
Separation at any time or the work of engaging work machine are also had both, clutch is selected to coordinate feeding mechanism 200 and transmission mechanism 300,
The operation is stable can be played, smooth engagement, separation is rapid, the convenient succinct and simple structure advantage of Operation and maintenance, and
Feeding clutch 110 and shearing clutch 120 are dry single-disk electromagnetic clutch, and dry single-disk electromagnetic clutch has ruler
It is very little small, light-weight, wear resistence and perfect heat-dissipating, the advantages of suitable for being frequently switched on and being quick on the draw.
The working characteristics of dry single-disk electromagnetic clutch is to generate magnetic force when coil is powered, under the action of electromagnetic force,
It is deformed the spring leaf of armature, Moving plate is pulled together with " armature ", and clutch is in engagement state；When coil blackout,
Magnetic force disappears, and " armature " rebounds under the action of spring leaf elastic force, and clutch is in discrete state.
Feeding mechanism 200 is the mechanism for pulling out the wire rod 600 of steel from disk coil holder comprising feeding motor 210 with
And friction pulley group 220, it is connected between the feeding motor 210 and the friction pulley group 220 by the feeding clutch 110,
Wire rod 600 to be sheared is mobile by the friction pulley group 220；It in simple terms, is exactly that feeding motor 210 drives friction pulley group
220 rotations, make friction pulley group 220 that wire rod 600 be driven to travel forward.
Current wire rod 600 is the Q235 steel of diameter 14mm, and the wire rod 600 without straightening, which will affect the normal stress of structure, to be made
Concrete cracking, therefore could use, 600 attribute elastic solid (Hookean body) of wire rod after many times needing to be straightened, elastic solid (Hookean body) by external force and
Deformation, so friction pulley group 220 is needed to carry out that transport is straightened.
