, use circle shear to cut the limit and have higher efficient and save power source at the steel plate below 25 millimeters for thickness.Circle shear comprises that the fixed disc that is arranged at cut deal rollgang both sides respectively cuts and removable circle shear, removable circle shear mainly is the cut deal that is adapted to different in width, both sides enter fixed disc and cut and removable circle shear in the steel plate course of conveying, roll and cut the limit action; Cut the problem whether synchronous in order to solve fixed disc, make the two synchronous operation by synchronizing shaft with removable circle shear, concordant with steel plate dual-side after guaranteeing to cut the limit; But, because the slitter edge after cutting needs scrap cutter to carry out broken limit, because the operation of the scrap cutter of both sides is variant, cause fixed disc to be cut and form difference with the removable circle shear speed of service, be difficult to guarantee synchronously, camber appears in back steel plate side or S shape is curved thereby cause cutting, and makes finished product steel plate qualification rate can not get guaranteeing; Simultaneously, because the wear extent that fixed disc is cut with removable circle shear might not be identical, though synchronous operation because the gap difference that wearing and tearing produce has caused steel plate to keep straight on, also can cause the steel plate side defective.
Therefore, need improve existing cut deal circle shear, can not be subjected to scrap cutter and fixed disc to cut influence with removable circle shear gap, assurance cut deal workpiece can straightly be advanced, thereby reduce even avoid occurring camber or the curved situation of S shape, guarantee the steel plate product qualified rate when increasing work efficiency.
The utility model content
In view of this, the utility model provides a kind of cut deal anti-deviation circle shear device, can not be subjected to scrap cutter and fixed disc to cut influence with removable circle shear gap, assurance cut deal workpiece can straightly be advanced, thereby reduce even avoid occurring camber or the curved situation of S shape, guarantee the steel plate product qualified rate when increasing work efficiency.
The anti-deviation circle shear device of cut deal of the present utility model, comprise that cut deal rollgang, the fixed disc that is arranged at cut deal transfer passage both sides respectively cut and removable circle shear, be positioned on the described cut deal rollgang fixed disc cut with removable circle shear before be provided for pinching the horizontal pinch roll structure of cut deal workpiece, described horizontal pinch roll structure comprises horizontal roller assembly and following horizontal roller assembly;
The described horizontal roller assembly of going up comprises that horizontal pinch roll is supported in two top pinch roll bearing blocks at horizontal pinch roll two ends with being respectively applied for to be rotatably assorted, and is provided with two and is used to drive the top pinch roll drive unit that the top pinch roll bearing block moves up and down with two top pinch roll bearing blocks are corresponding one by one;
Described horizontal roller assembly down comprises that horizontal pinch roll is supported in down two bottom pinch roll bearing blocks at horizontal pinch roll two ends with being respectively applied for to be rotatably assorted down; Described down horizontal pinch roll is provided with and is used to drive the bottom pinch roll drive motors that it rotates around self axis.
Further, described horizontal pinch roll vertically makes a concerted effort to be positioned on the longitudinal centre line of cut deal workpiece with following horizontal pinch roll to what the cut deal workpiece applied;
Further, described drive unit is a driving cylinder;
Further, described pinch roll driving cylinder is a hydraulic cylinder, and described hydraulic cylinder body is fixed in cut deal transfer passage frame, and plunger is fixedly connected on the top pinch roll bearing block downwards.
The beneficial effects of the utility model: the anti-deviation circle shear device of cut deal of the present utility model, employing fixed disc cut with removable circle shear before the structure of pinch roll is set, steel plate is applied suitable drag, its skew is formed constraint, thereby can not be subjected to scrap cutter and fixed disc to cut influence with removable circle shear gap, assurance cut deal workpiece can straightly be advanced, thereby reduce even avoid occurring camber or the curved situation of S shape, guarantee the steel plate product qualified rate when increasing work efficiency.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model pinch roll structural plan.
The specific embodiment
Fig. 1 is a structural representation of the present utility model, Fig. 2 is the utility model pinch roll structural plan, as shown in the figure: the anti-deviation circle shear device of the cut deal of present embodiment, comprise that cut deal rollgang 3, the fixed disc that is arranged at cut deal rollgang 3 both sides respectively cut 1 and removable circle shear 2, be positioned on the described cut deal rollgang 3 fixed disc cut 1 and removable circle shear 2 before be provided for pinching the horizontal pinch roll structure of cut deal workpiece, described horizontal pinch roll structure comprises horizontal roller assembly and following horizontal roller assembly;
The described horizontal roller assembly of going up comprises horizontal pinch roll 4 and is respectively applied for two the top pinch roll bearing blocks (being respectively top pinch roll bearing block 5 and top pinch roll bearing block 5a among the figure) that are rotatably assorted and are supported in horizontal pinch roll two ends, is provided with two and is used for driving the top pinch roll drive unit (figure is top pinch roll drive unit 6 and top pinch roll drive unit 7) that the top pinch roll bearing block moves up and down with top pinch roll bearing block 5 and top pinch roll bearing block 5a are corresponding one by one;
Described horizontal roller assembly down comprises down horizontal pinch roll 10 and is respectively applied for two the bottom pinch roll bearing blocks (being respectively top pinch roll bearing block 9 and top pinch roll bearing block 9a among the figure) that are rotatably assorted and are supported in down horizontal pinch roll two ends; Described down horizontal pinch roll 10 is provided with and is used to drive the bottom pinch roll drive motors 8 that it rotates around self axis.
