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, a kind of clutch feeding mechanism applied to cutter, comprising: feeding motor, from
Clutch 300, friction pulley group, fixed bearing material slot 500, movable bearing material slot 600, spring 700 and stroke baffle 800, and shear
Also there is the cutting mechanism for executing shear action in machine, in this cutter, by the way that clutch 300 is arranged, can be realized automatic
The effect of feeding shearing, under the coordination of clutch 300, when friction pulley group conveying wire rod 100 along fixed bearing material slot 500 and
When movable bearing material slot 600 arrives predetermined position, that is, when the end of wire rod 100 touches stroke baffle 800, clutch 300 divides
From friction pulley group stops operating, and then cutting mechanism cuts wire rod 100, and the wire rod 100 of cutting falls along movable bearing material slot 600
It falls, then clutch 300 engages, and continues to convey wire rod 100, and repeat above-mentioned movement, thus the slave disk by wire rod 100 in a steady stream
It is pulled out in material frame, and is constantly cut into one section one section.
Wherein, feeding motor 200 is to be fixedly installed, the wire rod 100 for affecting coiling to get up by friction pulley group, and will
It is to front haulage.
Clutch 300 is connected with the feeding motor 200, and clutch 300 acts on other than passing movement, also has both
Separation at any time or the work of engaging work machine, select clutch to coordinate feeding mechanism and transmission mechanism, can play work
Stablize, smooth engagement, separation rapidly, the advantage that Operation and maintenance are convenient succinct and structure is simple, and clutch 300 can be with
Dry single-disk electromagnetic clutch 300 is selected, dry single-disk electromagnetic clutch 300 has size small, light-weight, wear resistence and heat dissipation
Performance is good, the advantages of suitable for being frequently switched on and being quick on the draw.
The working characteristics of dry single-disk electromagnetic clutch 300 is to generate magnetic force when coil is powered, in the effect of electromagnetic force
Under, it is deformed the spring leaf of armature, Moving plate is pulled together with " armature ", and clutch 300 is in engagement state；Coil is disconnected
When electric, magnetic force disappears, and " armature " rebounds under the action of spring leaf elastic force, and clutch 300 is in discrete state.
Friction pulley group is connected with the clutch 300, and wire rod 100 is threaded through the friction pulley group, by described
Friction pulley group pushes the wire rod 100 mobile；In simple terms, it is exactly that feeding motor 200 drives the rotation of friction pulley group, makes friction pulley
Group pushes wire rod 100 to travel forward by frictional force.
Current wire rod 100 is the Q235 steel of diameter 14mm, and the wire rod 100 without straightening, which will affect the normal stress of structure, to be made
Concrete cracking, therefore could use, 100 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 is needed to carry out that transport is straightened.
Fixed bearing material slot 500 is fixed at the front side of the friction pulley group, and movable bearing material slot 600 is hinged on the fixation
The front end of bearing material slot 500, and wire rod 100, after friction pulley, into fixed bearing material slot 500, the activity of subsequently entering is held
In hopper 600, until the end of wire rod 100 touches stroke baffle 800, sheared to trigger cutting mechanism.
Herein it is worth noting that, 700 both ends of spring respectively with the fixed bearing material slot 500 and the movable bearing material slot
600 connections, the movable bearing material slot 600 to be supported on the fixed bearing material slot 500.
Hinge links are used between movable bearing material slot 600, fixed bearing material slot 500, movable bearing material slot 600 is lower to install spring 700,
Preferably, spring 700 can be in 45 degree of angles with fixed bearing material slot 500, inclined to support movable bearing material slot 600, so that movable
Bearing material slot 600, fixed this two parts of bearing material slot 500 are just at horizontality, when movable bearing material slot 600 is downward by one
When external force, spring 700 generates deformation by compression, and movable bearing material slot 600 tilts, and wire rod 100 is fallen along movable bearing material slot 600；
After external force disappears, movable bearing material slot 600 restores to the original state state under the action of spring 700.
Stroke baffle 800 is located at the front side of the movable bearing material slot 600, and separation is provided on the stroke baffle 800
Signal generator (is not drawn into) in figure, and the separation signal generator is electrically connected with the clutch 300.
In the actual working process, the corresponding movable bearing material slot 600 of length and fixed bearing material slot after wire rod 100 is sheared
The sum of 500 length, and the length of movable bearing material slot 600 is made to be slightly less than the length of wire rod 100, fix 500 length of bearing material slot
It is less than movable partial-length, the separation letter when stroke baffle 800 is touched on 100 top of wire rod, on stroke baffle 800
Number generator issues signal, is sheared on cutting mechanism, and clutch 300 separates, after cutting, in the gravity of wire rod 100
Under, movable bearing material slot 600 tilts, and wire rod 100 is fallen, and movable bearing material slot 600 restores under the action of spring 700, clutch 300
Engagement, friction pulley group continue to be fed forward wire rod 100.
