Detailed description of the invention

With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.

As shown in Figure 1 and Figure 2, cuing open cutter in steel plate of the present utility model, including frame 10, one end of described frame 10 to the other end is disposed with entrance jockey pulley 20, subdivision assembly and outlet jockey pulley 30, described entrance jockey pulley 20 and outlet jockey pulley 30 be arranged in parallel

Being provided with controller 40 in described frame 10, the frame 10 between described entrance jockey pulley 20 and subdivision assembly is provided with weld seam detector 50, described weld seam detector 50 is connected with controller 40；

Described subdivision assembly includes cutting 61, on cut drive mechanism 62, on cut lowering or hoisting gear 63, under cut 64, under cut drive mechanism 65 and under cut lowering or hoisting gear 66；Cut on described 61 with on cut drive mechanism 62 and be in transmission connection, above cut 61 with the entirety above cutting drive mechanism 62 composition with on cut lowering or hoisting gear 63 and be connected, described on cut lowering or hoisting gear 63 and be installed on frame 10 and be connected with controller 40；Cut under described 64 with under cut drive mechanism 65 and be in transmission connection, under cut 64 with under cut the entirety of drive mechanism 65 composition with under cut lowering or hoisting gear 66 and be connected, described under cut lowering or hoisting gear 66 and be installed on frame 10 and be connected with controller 40.

Entrance jockey pulley 20 is for regulating the entrance tension force of steel plate, and outlet jockey pulley 30 is for regulating the outlet tension force of steel plate, and drives steel plate to travel at the uniform speed.Entrance tension force is based on the width of steel plate, thickness determines, operator manually set unit tension, outlet tension force=unit tension (manual setting) × belt steel thickness × strip width.On cut drive mechanism 62 for drive on cut 61 rotations cutting steel plate, above cut lowering or hoisting gear 63 for regulation on cut 61 vertical position；Under cut drive mechanism 65 cut under driving 64 rotations and with on cut 61 and match common cutting steel plate, under cut lowering or hoisting gear 66 under regulation, cut the vertical position of 64.When subdivision steel plate, utilizing weld seam detector 50 to detect the position signalling of weld seam, and send the signal to controller 40, controller 40 calculates weld seam according to weld seam to the distance of subdivision assembly and the transmission speed of steel plate and moves to the time t of subdivision assembly.After steel plate continues to run with time t, cut in controller 40 control to cut in lowering or hoisting gear 63 drive and move on 61, cut under controlling under lowering or hoisting gear 66 drives simultaneously and cut 64 and move down, after weld seam is by subdivision assembly, then make to cut 61 and under cut 64 and return to original position and proceed subdivision.This device, above cut 61 and under cut 64 and operationally avoid weld seam, it is to avoid weld seam to above cut 61 and under cut 64 the impact of cutting edge, slow down the rate of wear, be conducive to improving service life.

Drive mechanism can be to use the mode such as motor, hydraulic-driven, it is preferred that cut on described drive mechanism 62 and under cut drive mechanism 65 and be motor.

Motor can directly with on cut 61 and under cut 64 and be connected, in order to above cut 61 and under cut the torque that 64 offers are bigger, make to cut 61 and under cut 64 holdings stably suitable cutting speed, described on cut drive mechanism 62 by upper reducer 67 with on cut 61 and be connected；Cut under described drive mechanism 65 by lower decelerator 68 with under cut 64 and be connected.

On cut lowering or hoisting gear 63 and under cut lowering or hoisting gear 66 and may each be the jacking equipment such as hydraulic cylinder, cylinder, it is preferred that cut lowering or hoisting gear 63 on described and include air motor, described air motor by worm and worm gear with on cut drive mechanism 62 and be connected.Worm and worm gear cuts the up and down motion of drive mechanism 62 on the rotational motion of air motor being changed into, it is achieved above cut the vertical position regulation of 61.Cutting lowering or hoisting gear 66 under described is servomotor, and described servomotor is connected with lower decelerator 68.It is high that servomotor has control accuracy, the advantages such as output is big, it is possible to cuts 64 up and down motions under driving exactly.

Described servomotor is band-type brake servomotor.On cut 61 and under cut after the vertical position of 64 sets, cut in 64 Serve Motor Control under, simulated machine band-type brake controls, as long as servomotor does not runs, just to one opposing torque of servomotor, the steel plate making motor not passive movement drives and inertia rotates, thus solves subdivision and cut 64 allokinetic problems.

In order to ensure that steel plate is cut open by thoroughly cutting, on cut 61 and under cut between 64 horizontal range should be maintained in certain scope, in order to cut on regulating 61 and under cut between 64 horizontal range, the gap adjustment servomotor 69 cutting 61 axial locations in regulation it is provided with in described frame 10, described gap adjusts servomotor 69 and is connected with upper reducer 67, in order to realize being automatically adjusted, gap adjusts servomotor 69 and electrically connects with controller 40.

For the ease of determining regulated quantity, described frame 10 is provided with cut in detection 61 and under cut the gap sensor 70 of horizontal range between 64, described gap sensor 70 electrically connects with controller 40.Cut in gap sensor 70 detection 61 and under cut between 64 horizontal range value and be transferred to controller 40, controller 40 control again gap adjust servomotor 69 drive upper reducer 67 with on cut 61 integral levels and move to correct position.

Controller 40 can be computer etc., in order to and convenient to operate, cost-effective, it is preferred that described controller 40 is PLC.
