The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
Shown in Fig. 1-4.
A kind of wide cut stainless steel product shearing device, it comprises sawing dolly 1 and road wheel 2, sawing dolly 1 is installed on four road wheels 2; As shown in Figure 1, on the described sawing dolly guide bar support 3 is installed, the two supports of guide rod 4 is on the guide bar support 3 of correspondence; The quantity of guide rod is two symmetric arrangement, and is as shown in Figure 2, and the sliding sleeve 5 that can on guide rod 4, move around is installed on the guide rod 4; As shown in Figure 1; Sliding sleeve 5 can be made up of deckle board 12 and bearing holder (housing, cover) 13, and rolling bearing is installed in the bearing holder (housing, cover) 13, and rolling bearing is sleeved on the guide rod 4 and with deckle board 12 and is fixedly linked; Sliding sleeve 5 links to each other with the piston rod of extension sleeve oil cylinder 6 on being installed in sawing dolly 1 through connecting plate 17, and described extension sleeve oil cylinder 6 is installed on the cylinder bracket 16, and cylinder bracket 16 is fixedly mounted on the sawing dolly 1, and is as shown in Figure 3; In the bottom of sliding sleeve 5 saw arm 7 is installed; Saw arm axle 8 is installed in the saw arm 7; One end of saw arm axle 8 is equipped with saw blade 9, and saw blade 9 can be fixed on the saw arm axle 8 with right chuck 15 through left chuck 14, and is as shown in Figure 4; The other end of saw arm axle 8 is equipped with the belt pulley 10 that drives its rotation, and belt pulley 10 links to each other through the output shaft of driving-belt with the motor 11 that is installed in sliding sleeve 5 tops.
The sawing dolly is a main body of the present invention; The structural shape of sawing dolly is saw blade high speed rotary-cut on the work top that supports with two location guides, and the work top that its two location guides support is supported by four linear motion bearings again and promoted by middle extension sleeve oil cylinder.Slowly promote the rotary-cut saw blade rotary-cut stainless steel product that travels forward by middle extension sleeve oil cylinder.The size of hydraulic jack stroke has determined the width of sawing product, and the diameter of rotary-cut saw saw blade has determined the height of sawing product.And the integral body that work top on the sawing dolly and middle extension sleeve oil cylinder promote to form is synchronized with the movement by direct current generator driven wheel tooth bar (not shown) promotion random groups mill speed.The start position of coping saw blade and operating position are on same plane, so the position of saw blade is lower, and the better working stability of sawing dolly.Front and back at rotary-cut saw are equipped with clamping device, and saw blade laterally advances rotary-cut forward during sawing, and saw blade begins and saws out from the shaped steel top from the shaped steel waist at first.Therefore the sawing impulsive force is less and make shaped steel sawing deformed area less, and burr is few during rotary-cut.Rotary-cut mechanism is furnished with cycle of higher pressure cooling emulsion spray system during rotary-cut, eliminated the sawing distortion basically and significantly reduced the defective of sawing burr.Improved the sawing quality of sectional shape.
Servomotor drives belt pulley, pushes away mandrel, on the work top that two location guides support, back and forth back and forth promotes sawing product by four linear motion bearings supports and by middle extension sleeve oil cylinder through saw arm drive rotary-cut saw blade, saw arm during rotary-cut.
Scale saw cutting system of the present invention also comprises photoelectricity fixed ruler baffle mobile device, the electric numerically controlled control system of PLC.For sawing process is effectively controlled, adopt by the electric numerical control control of PLC servo-actuated dolly to start, the sawing of hydraulic jack, the control of clamping device before and after the rotary-cut saw, the control of photoelectricity fixed ruler baffle, electric control gear can adopt routine techniques to realize.
After shearing device of the present invention is installed in the sizing arbor press; The stainless steel product that moves with mill speed accurately rotary-cut be required cut lengths; Shearing device must accurately be coordinated with the motion of unit; Especially when unit speed changed, the manufacturing technique requirent shearing device must get off to carry out cutting to length with the situation that the unit linear velocity keeps following the tracks of synchronously.The key issue of control system is that how making the distance between shearing device and stainless steel product just in time is the preseting length of scale product in dolly and bar rolling speed synchronous moment.
Therefore rotary-cut saw basic technology is required to be: for the otch section that guarantees rotary-cut straight, in whole rotary-cut process, the rotary-cut saw blade all should with the stainless steel product axis normal, and to make the rotary-cut saw curved not flat.The rotary-cut saw blade must be synchronous with the shaped steel of operation in the sawing process, guarantees that in sawing process the rotary-cut saw blade should rotate around mandrel, applies rotary-cut and sawing power, move with identical speed with stainless steel again, assurance shaped steel product to be cut off face straight.
Operation principle of the present invention is when institute's rolled products passes rotary-cut saw numerical control impulse generator counting and reaches cut lengths, by the PLC programmable controller, sends and clamps order; The clamping device of both sides clamps product rapidly before and after the rotary-cut saw; And drive the rotary-cut saw and travel forward synchronously with mill speed, hydraulic jack drives shearing device and gets into the sawing position, after the sawing product is sawed in rotary-cut; Clamping device is unclamped in the instruction of PLC electric-control system; Sawing cylinder homing, sawing servo-actuated dolly are by the reposition of walking hydraulic oil cylinder driving, and beginning is next to circulate.
Invention does not relate to all identical with the prior art prior art that maybe can adopt of part and realizes.
