Abstract
The utility model relates to a direct measurement control system for the shear length of a cross shearing unit, which comprises a photoelectric switch or a grating ruler, a servo motor, a feed roller and a plate shearing machine. The photoelectric switch or the grating ruler is used for directly measuring the length of shorn material, and measuring signals are used for controlling the shear motion of the plate shearing machine, therefore, the accurate control of the shorn material is realized.
Description
Technical field
The utility model belongs to sheet machining apparatus, as the metal coiled material crosscut unit cutting length control system of opening a book.
Background technology
At present, the sheared length of known metal coiled material crosscut unit is general adopts following two kinds of methods control: 1 utilize one can lifting the mechanical shutter decision shear the length of material; 2 utilize the driven by servomotor feeding roller, shear the length of material by the umber of pulse decision of control servomotor.These two kinds of methods all can not accurately be controlled the length of shearing material.The first method coiled strip clashes into when contacting with positioning baffle, because each impact is difficult to unanimity, the length of shearing material will produce error, and the steel plate movement velocity is high more, and error is big more.Second method can accurately be controlled the rotating speed of feeding roller, but the surface state difference of sheet material, friction between feeding roller and the sheet material is a variable, and (for example surface of steel plate scribbles antirust oil, will produce slip between steel plate and feeding are rolled) is so can not accurately control the length of shearing material.
Summary of the invention
Control the weak point of existing two kinds of methods in order to overcome metal coiled material crosscut unit sheared length, the utility model provides a kind of direct measurement and control system of crosscut unit sheared length, utilize new control method can accurately control the shear precision of sheet material, the length precision of sheet material is controlled at ± 0.05mm.
The scheme that its technical problem that solves the utility model adopts is:
A kind of direct measurement and control system of crosscut unit sheared length is made up of optoelectronic switch or grating chi, servomotor, feeding roller and plate shearing machine; Directly measure the length of shearing material with optoelectronic switch or grating chi.
The concrete scheme of implementing is: two optoelectronic switches are installed below the expansion roll bending of high-speed motion, first optoelectronic switch control servomotor, allow the feeding roller of high-speed motion slow down, second optoelectronic switch is high-precision position-sensing switch, the action of control plate shearing machine, the accurate control that realizes shearing material.
The concrete scheme of implementing two is: steel plate is when the sheared length of approaching setting, promote a grating chi that is installed on the line slideway, when steel plate arrives the sheared length of setting, the shear action of the signal controlling plate shearing machine of grating chi, the accurate control that realizes shearing material.

Among the figure: 1. idler pulley, 2. plate shearing machine, 3. steel plate, 4. descend feeding roller, go up feeding roller 6. servomotors.
The specific embodiment
In Fig. 1, servomotor 8 drives a pair of feeding roller 6,7 traction steel plates and moves in the direction of arrows, carrying roller 3 is supporting steel plate 5, when steel plate arrives the position of optoelectronic switch 2, servomotor 8 slows down, allow the steel plate microinching, when steel plate arrived the position of optoelectronic switch 1, plate shearing machine 4 scissors fall cut off steel plate 4.Because optoelectronic switch 1 is high-precision position-sensing switch, and steel plate 4 arrives the position of optoelectronic switch 1 stably with very slow speed, so can guarantee the length precision of steel plate shearing.
In Fig. 2, during the sheared length of steel plate 5 approaching settings, promote a grating chi 2 that is installed on the line slideway 9, when steel plate 5 arrived the sheared length of setting, the shear action of the signal controlling plate shearing machine of grating chi 1 realized the accurate control that shearing is expected.
In Fig. 3, the length of shearing material is that the steel plate 5 that blocks after baffle plate 2 rises in the motion is determined.Every shearing once, steel plate and baffle plate bump is once.Because each impact is difficult to consistent, so sheared length can not get accurate control.
In Fig. 4, shear the length of material and determine with the revolution of servomotor control feeding roller.Because the surface state of steel plate is difficult to be consistent, (for example there is oil on the surface of sheet material, sheet material in uneven thickness or the like) is so sheared length also can not get accurate control.
