Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
With reference to Fig. 7, device overall structure of the present invention is, comprises main part, middle pressure roller, edge supporting plate and inlet/outlet carrying roller, middle carrying roller composition.
With reference to Fig. 1, Fig. 2, Fig. 3, main part structure is,
Comprise bearing 1 and roll stand 2, bearing 1 arrival end is provided with inlet pressure cylinder 6, and inlet pressure cylinder 6 piston rod end passes downwardly through connecting pin 1 and is connected with roll stand 2; Bearing 1 port of export is provided with outlet hydraulic cylinder 7, and outlet hydraulic cylinder 7 piston rod end passes downwardly through connecting pin 29 and is connected with connecting rod 10, and connecting rod 10 is connected with roll stand 2 by another connecting pin 1; Be provided with multiple edge pressure roller 3 (in figure, embodiment is six edge pressure rollers 3) in the chassis of roll stand 2, edge pressure roller 3 is sleeved on fixed axis 5 by rolling bearing 4, and fixed axis 5 is fixedly mounted in roll stand 2.Above-mentioned bearing 1, roll stand 2, edge pressure roller 3, inlet pressure cylinder 6 and outlet hydraulic cylinder 7 form action subject;
On the cylinder head (i.e. cylinder rod end head) of inlet pressure cylinder 6, be also provided with support plate 11, be provided with pull bar 12 in support plate 11 horizontal arm in stomidium, pull bar 12 lower end is hinged by hinge 13 and roll stand 2, and pull bar 12 upper end is provided with ball ring 14 and nut 15.
Usually need two limits of shearing steel plate, these two limits must compress simultaneously, so must arrange a set of identical flange fixing installation respectively at left and right sides, the edge pressure roller 3 of identical flange fixing installation is overlapped in left and right two can one-sided action, also can both sides synchronization implementation.
The position of edge pressure roller 3, along steel plate width direction, from edge more close to, effect is better; Along steel plate length direction, from share zone then the closer to better.In view of the conflict that both space cloth are set up, because miscellaneous part position limit, the edge compacted position of edge pressure roller 3 haves no alternative but some distance total from steel plate edge.
Former and later two bearings 1 are fixed on the tool rest of end trimming shears body, transfixion, are the bases of whole edge pressure roller automatic regulating apparatus.
The cylinder body of inlet pressure cylinder 6 and outlet hydraulic cylinder 7 is directly fixed on bearing 1.Inlet pressure cylinder 6 and outlet hydraulic cylinder 7, each via the proportional valve control of correspondence, realize the Stress control of edge pressure roller 3; Two hydraulic cylinder (inlet pressure cylinder 6 and outlet hydraulic cylinder 7) built-in linear displacement transducers, for measuring hydraulic cylinder actuating length, are set by auto-programming, control edge pressure roller 3 position, thus the position realizing edge pressure roller 3 are presetting.
In embodiment, every side is provided with six edge pressure rollers, 3, six edge pressure rollers 3 and rolling bearing 4 is connected in roll stand 2 by fixed axis 5.Edge pressure roller 3 is free roll, and itself is V belt translation not.Edge pressure roller 3 with the one-sided pressure of roll stand 2, also can be depressed both sides simultaneously, and these two kinds of control models of edge pressure roller 3, according to practical condition and result of use, preferentially can select.
The thrust of each edge pressure roller 3 is distributed, from the inlet to the outlet, and can only be more and more less.That is, the aperture of pressure roller roll stand 2, outlet can not be less than entrance forever.Once the pressure roller of the port of export is lower than arrival end, the nut 15 on pull bar 12 will be expressed on ball ring 14, and restriction roll stand 2 port of export continues to lower swing.Overlap special mechanical limit structure by this, realize synchronous limit function before and after inlet/outlet.
Flattening effect to obtain desirable compression, preventing from swelling in the middle part of steel plate, also needing to compress with edge to cooperatively interact, also will compress in the middle part of steel plate.
Figure 4 shows that middle pressure roller front view, middle roller structure is, comprise upper bracket 16, upper bracket 16 is fixed in the frame of end trimming shears entrance permanent plant, upper bracket 16 is connected with extension spring 17 upper end, extension spring 17 lower end and swing arm 18 hinged, rotating fulcrum and the upper bracket 16 of swing arm 18 are hinged, and swing arm 18 other end is provided with middle pressure roller 19 by rotating shaft 20.Normal operating conditions, extension spring 17 is all the time proposed swing arm 18, and swing arm 18 is actual is a lever, middle pressure roller 19 under the effect of extension spring 17 spring force, to applying certain thrust in the middle part of steel plate.
Fig. 5 is edge supporting plate and inlet/outlet idler structure schematic diagram.The steel plate bending distortion caused to prevent overvoltage, move towards both sides along steel plate and be provided with edge supporting plate, edge supporting plate is arranged in both sides along steel plate length direction, comprise front supporting plate 21 and back supporting plate 22 successively, the edge supporting plate (with inlet/outlet carrying roller) on both sides is in order to offset the thrust of pressure roller.For preventing excessive press-bending distortion, steel plate also needs moderately oppositely to support, just just work when steel plate bends and is out of shape very large, certain distance is had under normal circumstances from steel plate, inlet/outlet carrying roller comprises the entrance carrying roller 23 being arranged on steel plate entry position and the outlet carrying roller 24 being arranged on steel plate exit position, when the effect of entrance carrying roller 23 and outlet carrying roller 24 mainly ensures that steel plate can advance along production line absolute altitude, taking the lead of steel plate can not be sagging.
Fig. 6 is middle idler structure schematic diagram, and in order to coordinate edge roller to adjust better, suitable entrance tension adjustment and straightway slitter edge lead also very important, also very direct on the impact of trimming quality.In operation, middle part, because of the effect of deadweight, middle pressure roller power and accidental side force, also there will be the possibility of the waist that collapses to steel plate.Centre position between entrance carrying roller 23 and outlet carrying roller 24 has been located bracket 25, and bracket 25 upper surface is provided with multiple middle carrying roller 26, and bracket 25 importer is made as ramp shaped to end, enters end trimming shears have good guiding function to steel plate.
