Technical field
The present invention relates to transformer parts manufacture field, in particular to a kind of transformer silicon steel sheet processing high speed is horizontal to cut
Line.
Background technique
Silicon steel sheet transverse shear line mainly for the production of transformer silicon steel sheet, silicon steel sheet transverse shear line generally by discharging device,
Feed device, feeding passage, hole punched device, V cut device, shear, material-gathering device and control centre's composition, and wherein feeding fills
It sets, hole punched device, V cut device and shear is successively set on feeding passage.Traditional silicon steel sheet transverse shear line has below
Disadvantage: 1, the feeding passage longitudinal length of silicon steel sheet transverse shear line generally has several meters, and rising for feeding passage is arranged in feed device
Point position, feed distance is longer, and every volume silicon steel sheet causes several meters of waste materials, wastes material.2, feed device uses propelling movement type feeding,
And conveying distance is long, when the silicon steel sheet of conveying is relatively narrow or relatively thin, the deformation such as is easy to appear distortion in feeding process, heaves, it is difficult
To improve feeding speed.3, feed device at a distance from shear farther out, influenced after long range feeding shearing precision.4, it passes
Unite silicon steel sheet transverse shear line feeding passage on be provided with a hole punched device and a V cuts device, silicon steel sheet is punched out and
When cutting V-notch, need to be carried out in three steps: the first step is that hole punched device first rushes circular hole to silicon steel sheet, and silicon steel sheet continues defeated forward
It send；Second step is that V cuts device and cuts V-notch to silicon steel sheet, and silicon steel sheet continues to be fed forward；Third step is hole punched device to silicon steel
Piece rushes second circular hole, and two circular holes are symmetrically distributed in V-notch both sides.The three-wave-length operation limit of traditional silicon steel sheet transverse shear line
The raising of silicon steel sheet production efficiency.5, the shear of traditional silicon steel sheet transverse shear line is usually fixed, can not adjust the angle of shear
Degree, narrow application range.6, the material-gathering device of traditional silicon steel sheet transverse shear line is that high speed discharges, silicon steel sheet fly out after conveyer belt using from
Lower lock block under above depresses silicon steel sheet, so that it is fallen in setting place, but this method safety is low, the silicon steel sheet being collected simultaneously
It is irregular, it needs to put into manpower and carries out stacking arrangement, influence efficiency, waste of manpower resource.
Therefore, for above-mentioned phenomenon, just refer to that a kind of novel numerical control silicon steel sheet is horizontal to be cut in patent CN105397495A
Line equipment, including control centre, discharging device, feeding passage are disposed on feeding passage: preposition feed device, first

It has the advantage that setting front and rear feed device, reduces sheet material waste, improve shear precision, avoid distortion and the drum of silicon steel sheet
It rises, realizes the high speed conveying of silicon steel sheet；First hole punched device and the second hole punched device are symmetrically distributed in front of and after V mouthfuls of shears
Side, a step punching, saves the time, improves production efficiency；Material-gathering device cooperates lamination stacking table using Magnetic Conveyor Belt, automatically will shearing
Good silicon steel sheet neatly stacks, and reduces worker operation, saves human resources, improves efficiency.
Above-mentioned cut-to-length equipment fills punching during being punched out to silicon steel sheet, rushing V mouthfuls and cut
Set, V mouthfuls of shears and pendulum cut device, by by V mouthful shears be designed as can transverse shifting so that hole punched device and
V mouthfuls of shears can be realized synchronous blanker and make, still, for hole punched device and pendulum cut device or V mouthful shears and
Pendulum cuts shear action between device, is still that needs carry out distribution cutting, working efficiency be not still it is very high, in addition, for two
Lateral distance between hole punched device is fixed, in this way, the hole on the silicon steel sheet to different size is resulted in be punched out
When, it is still necessary to substep punching is carried out, and increases shear time required for same silicon steel sheet, reduces working efficiency.
