The location of High Rotation Speed flying shear blade and balancing

Technical field

The utility model relates to a kind of flying shear blade equipment, particularly relates to a kind of location and balancing of High Rotation Speed flying shear blade.

Background technology

In existing production equipment, the location of High Rotation Speed flying shear blade and the affirmation of zeroing, it is the core of high-speed flying shear control always, because accumulated error and orientation problem that the high-speed flying shear control system exists, often cause the flying shear blade location inaccurate, and then cause that the product error is larger, and affect the quality of product.

The utility model content

In view of this, the utility model provides a kind of location and balancing of High Rotation Speed flying shear blade, pass through the technical program, utilize rotary encoder as the position probing of flying shear blade, counting by rotary encoder, draw the corresponding flying shear blade diverse location of different pulse number, and cooperate the interrupt routine of PLC by the approach switch that is installed on the flying shear blade end, eliminate the cumulative errors of rotary encoder, thereby realize the starting of flying shear. accelerate, shear, continuous cataclasm shearing is finished in braking and location.

In order to achieve the above object, the technical solution of the utility model is achieved in that a kind of location and balancing of High Rotation Speed flying shear blade, adopt PLC to control the rotating speed of transmission device, flying shear motor and gear-box and power transmission shaft in the existing High Rotation Speed flying shears, turning cylinder at the High Rotation Speed flying shears is provided with rotary encoder, in described flying shear blade end approach switch is set.

Described rotary encoder is electrically connected with PLC respectively mutually with approach switch.

When work, count by the rotary encoder that is arranged on the turning cylinder, corresponding flying shear blade diverse location when detecting different pulse number, in the flying shear blade end approach switch is set, realize that by PLC and approach switch interrupt routine carries out zero clearing, restart counting, wrong in order to the tired note of the counting error of eliminating rotary encoder, give transmission device with analog output module output speed set-point, thereby realize starting, acceleration, shearing, braking and the location of flying shear blade, finish continuous cataclasm shearing.

Beneficial effect after the employing technique scheme is: a kind of location of High Rotation Speed flying shear blade and balancing, pass through the technical program, industry and civil area High Rotation Speed flying shear blade location and fixed zero provide a kind of simple device, simple in structure, the accurate positioning of the utility model are provided.Realize easily.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the technical scheme in the utility model is described in further detail.

Location and the balancing of the High Rotation Speed flying shear blade that the utility model relates to, employing PLC15 controls the transmission device 1 in the existing High Rotation Speed flying shears, the rotating speed of flying shear motor 2 and gear-box and power transmission shaft 3, count by the rotary encoder 5 that is arranged on the turning cylinder 4, corresponding flying shear blade 6 diverse locations when detecting different pulse number, in fixed position, flying shear blade 6 end approach switch 7 is set, when flying shear blade 6 is pressed its movement locus through approach switch 7, approach switch 7 sends signal to the input module 13 of PLC15, PLC15 realizes carrying out zero clearing by interrupt routine, restart counting, in order to the tired note of the counting error of eliminating rotary encoder 5, thereby guarantee the accuracy of flying shear blade 6 location.Because the position of approach switch 7 is fixed, the PLC15 interrupt routine is not affected by the sweep time of PLC15, makes the zero setting of flying shear blade 6 put accurate.Give transmission device 1 with PLC15 analog output module output speed set-point, transmission device 1 drives flying shear motor 2, flying shear motor 2 links to each other with flying shear blade 6 by shaft joint, thereby by starting, acceleration, shearing, braking and the location that the PLC15 programme-control realizes flying shear blade 6, finish continuous cataclasm shearing.

The motion stage of described flying shear blade 6 is divided into startup stroke 8, cutting stroke 9, braking distance 10, antiport stroke 11 and the location stroke 12 of oppositely creeping, it overlaps the starting point that starts stroke 8 and the end point of the location stroke 12 of oppositely creeping, and the flying shear shear rate of flying shear blade 6 will satisfy from cutting stroke 9 beginnings and stops when oppositely creeping location stroke 12 end.

Turning cylinder 4 at the High Rotation Speed flying shears is provided with rotary encoder 5, in flying shear blade 6 ends approach switch 7 is set, and described rotary encoder 5 is electrically connected with PLC 15 respectively mutually with approach switch 7.

In the utility model, the automatic location of High Rotation Speed flying shear blade 6 is the most crucial parts of High Rotation Speed flying shear control system, and there is not the possibility of manual control in this part when normally producing; The utility model selects high-precision rotary encoder 5 to make the position probing of flying shear blade 6, by the counting of rotary encoder 5, can draw corresponding flying shear blade 6 diverse locations of different pulse number; Cumulative errors for rotary encoder 5, cooperate the interrupt routine of PLC 15 to eliminate with the high accuracy approach switch 7 that is installed on flying shear blade 6 ends, after namely detecting high accuracy approach switch 7 signals of flying shear blade 6 ends at every turn, adopt immediately interrupt routine, with the count value zero clearing of high speed counting module, restart counting; The control logic of flying shear blade 6 realizes by PLC15, the enabling signal of flying shear blade 6 is by hot metal detector or manually given, by digital quantity input module 13 inputs, after the control logic of finishing via software is processed, give transmission device 1 by analog output module output speed set-point, thereby realize starting, acceleration, shearing, braking and the location of flying shear, finish continuous cataclasm shearing work.

The above only is better possible embodiments of the present utility model, is not to limit the utility model protection domain.
