Specific embodiment
The following is specific embodiment of the invention and with reference to accompanying drawing, technical scheme is further described,
But the present invention is not limited to these embodiments.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, a kind of cutter, the wire rod 600 for shearing steel, firm wire rod 600
The length of setting is cut into, including：Clutch, feed mechanism 200, transmission mechanism 300 and cutting mechanism 400, cutter
On be additionally provided with frame, for carrying above-mentioned mechanism, wire rod 600 is coiled in biscuit frame, is then fed machine
Structure 200 is involved, and is entered on cutting mechanism 400, and one section one section is cut into by cutting mechanism 400.
In this cutter, by setting clutch, the effect of self-feeding shearing can be realized, in clutch
Under coordination, when the conveying wire rod 600 of feed mechanism 200 arrives precalculated position, clutch stops feeding structure, and starts biography
Motivation structure 300, transmission mechanism 300 is that cutting mechanism 400 transmits power, cuts the wire rod 600 of preseting length, and in clutch
Under the coordination of structure, feed mechanism 200 is set to continue feeding, and cutting mechanism 400 is stopped shearing.
Wherein, clutch includes feeding clutch 110 and shearing clutch 120, when 110 points of the feeding clutch
From when it is described shearing clutch 120 engage；Feeding clutch 110 and shearing clutch 120 effect except transmit motion in addition to,
Also have separation at any time or the work of engaging work machine concurrently, select clutch to coordinate feed mechanism 200 and transmission mechanism 300,
Working stability can be played, smooth engagement separates rapid, the advantage of the convenient succinct and simple structure 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 chi
It is very little small, lightweight, wear resistence and perfect heat-dissipating, it is adaptable to frequently start and sensitive advantage.
The working characteristics of dry single-disk electromagnetic clutch is to produce magnetic force in coil electricity, in the presence of electromagnetic force,
It is deformed the spring leaf of armature, Moving plate is pulled together with " armature ", clutch is in engagement state；During coil blackout,
Magnetic force disappears, and " armature " rebounds in the presence of spring leaf elastic force, and clutch is in released state.
Feed mechanism 200 is the mechanism that the wire rod 600 of steel is pulled out from disk coil holder, it include feeding motor 210 with
And friction pulley group 220, connected by the feeding clutch 110 between the feeding motor 210 and the friction pulley group 220,
Wire rod 600 to be sheared is moved by the friction pulley group 220；In simple terms, it is exactly that feeding motor 210 drives friction pulley group
220 rotate, and make friction pulley group 220 drive wire rod 600 to travel forward.
Current wire rod 600 is the Q235 steel of diameter 14mm, and the wire rod 600 without straightening can influence the normal stress of structure to make
Concrete ftractures, therefore could be used after many times needing to stretch, the attribute elastic solid (Hookean body) of wire rod 600, and elastic solid (Hookean body) is by external force effect
Deformation, so need the friction pulley group 220 to carry out stretching transport.
Transmission mechanism 300 is the Power Component of cutting mechanism 400, is that cutting mechanism 400 provides shearing force, and it includes transmission
Motor 310 and multi-stage gear group 320, the multi-stage gear group 320 is by shearing clutch 120 and the driving motor
310 connections；In simple terms, it is exactly that, when the engagement of clutch 120 is sheared, multi-stage gear group 320 links with driving motor 310 and connects
Connect, cutting mechanism 400 performs shearing motion, when shearing clutch 120 and separating, 310 points of multi-stage gear group 320 and driving motor
From.
