Description
Technical field
The invention belongs to the sheet metal correcting device, be specifically related to crucial the finishing equipment---multi-roller steel plate-flattening machine in steel plate production and the processing.
Background technology
The slab arbor press is to the crucial finishing equipment in steel plate production and the processing in smelter, frame for movement factory.Existing slab arbor press, usually working roll generally has 9～21, mainly comprise frame, entablature, sill, working roll, backing roll, screw-down, articulated beam, working roll driving motor, reductor, gear distribution box etc., the working roll in two rows same roller footpath is staggeredly arranged in parallel or the row's of going up working roll small inclination is arranged, importing and exporting before and after the arbor press respectively has a pair of drawing of arranging up and down to expect and discharge roller.As China Patent No. be: CN200510018681.5 discloses the change roller counting roller type levelling machine of a kind of differential roller apart from the roller footpath, become roller counting roller type levelling machine working roll number and become many by few, the precision of correcting sheet material improving is called on less than the working roll roll spacing roller footpath of preceding shelves in the working roll roll spacing roller footpath of every grade of increase.In the art, theoretical according to the sheet bending rectification as everybody knows, improve the precision of correcting sheet material and depend primarily on the roller number of arbor press and the drafts of the working roll that sheet bending is out of shape, and working roll roller footpath and roll spacing.We think that this arbor press is not too big for improving the effect of sheet material rectification precision.
The parameter of the main foundation of design of existing arbor press is that institute is by the thickness range of rectification steel plate slab, the bend yield strength noted of steel plate.For this reason, every arbor press all has the thickness range of correcting steel plate, and arbor press is divided into the thickness range of correcting steel plate: thin plate arbor press (the thick 2mm of steel plate is following), middle plate arbor press (thick 4～24mm), the cut deal arbor press (steel plate thick 4～40mm) of steel plate.Along with the rolled plate development of technology, the scope of plate mill rolled plate thickness is enlarging (steel plate thick 2～200mm), so just require arbor press to correct the very big (steel plate thick 2～80mm) of thickness range of steel plate, it will be very huge adopting above-mentioned arbor press technical pattern, and be difficult to satisfy simultaneously the thick rectification required precision of different steel plates.
Summary of the invention
The deficiency that purpose of the present invention exists at prior art, for satisfying the very big requirement of thickness range of correcting steel plate, design a kind of according to being adjusted roller number and the roller footpath that participates in correcting steel plate work, compact conformation by rectification steel plate thickness, volume is less, the multi-roller steel plate-flattening machine that weight is lighter.
For achieving the above object, the present invention adopts technical scheme to be:
Multi-roller steel plate-flattening machine comprises the driving motor and the reductor of the working roll that is provided with on frame, entablature, sill, moved cross beam, moved cross beam and the sill and the screw-down on backing roll device, moved cross beam and the frame, working roll, it is characterized in that: described working roll and backing roll device have three parts, are respectively import and export part, and mid portion; The top working roll of three parts and backing roll device all can be adjusted up and down, and with being contained in below the moved cross beam; Import and export partly is pony roll footpath, pony roll distance, and the roller number is 3～9, and the centre is big roller footpath, big roll spacing, and the roller number also is 3～9.
Between the working roll of above-described import and export part and backing roll device and the moved cross beam trace is housed and adjusts screw-down up and down.
Between the working roll of above-described import and export part and mid portion, can adjust the intermediate roller device of depressing and opening separately in addition; Intermediate roller device is provided with the screw-down of depressing and opening fast, and intermediate roller device can be realized adjusting in the aligning process and depress and open fast.
Three parts of above-described working roll and backing roll device, each part each has independently motor transmission; The working roll of various piece is the segmentation transmission, intermediate calender rolls is respectively with a motor transmission, each driving motor has speed regulating control equipment, speed governing makes the correcting process light plate produce tension force, and be furnished with industrial computer or Programmable Logic Controller, adjust and control the rotating speed of each section working roll, control the tension force size of correcting steel plate.
Above-described import and export part and intermediate calender rolls screw-down separately are the wedge screw-down.
The above-described working roll of opening intermediate roller device and mid portion soon has a transmission device.
The multi-roller steel plate-flattening machine of the present invention design compared with prior art, outstanding substantive distinguishing features and significant technological progress are:
1, owing to adopted the working roll of the upper and lower crossbeam setting in the frame and the layout of backing roll device to be divided into three parts, import and export part, and the distribution mode of the working roll of mid portion are arranged, and import and export is pony roll footpath, pony roll distance, the centre is the structure of the working roll of the big roll spacing in big roller footpath, and the thickness range that makes arbor press correct steel plate increases.An arbor press promptly can be corrected thin steel plate, also can correct medium plate and super-thick steel plate, and guarantees and improved the rectification precision of various different-thickness steel plates.
2, the working roll of three parts and backing roll device have and can independently depress guiding mechanism, correct the depressing according to the very easy adjustment of thickness of correcting steel plate of working roll, and according to correcting the thick of steel plate, the working roll of three parts carry out different combinations and participates in correcting steel plate.
3, owing to adopt import and export part, mid portion, reach intermediate calender rolls individual motor transmission is separately arranged.Both working roll was the segmentation kind of drive, each driving motor makes the correcting process light plate produce tension force under speed regulating control, and by industrial computer or Programmable Logic Controller adjustment and control the rotating speed of each section working roll, thereby realize the tension force size of control rectification steel plate, can make by the smooth precision of rectification high intensity cold steel plate to be greatly improved.
4, compact conformation, volume is less, and weight is lighter, and the thickness range of correcting steel plate is big.
