Two shearing devices are in bilateral symmetrical and in the same structure and are respectively disposed on a guide rail of the frame. Cutter shafts are provided with inner splines. The drive shaft is provided with outer splines. The cutter shafts are sleeved on the drive shaft by spline connection. Opposing ends of the two cutter shafts are provided with two to four cutter grooves respectively, two to four cutter edges are disposed in the cutter grooves through screws and compressive springs. A support plate is fixed on a box. A shearing plate is disposed on the support plate and is made of low hardness wear-resistant material. A speed regulating motor of an openness device is arranged at the other end of the frame and drives a screw to rotate. The box of the shearing devices is provided with a threaded hole. The screw is in threaded connection with the two shearing devices to drive the two shearing device to slide on the guide rail of the frame. By the use of the scrap chopper for plate and strip rolling, the defects caused by lateral clearances are eliminated, rigidity impact on shearing edges and the shearing plate is lowered and damage of the shearing edge and a lower cutter is prevented.
Description
Technical field
The invention belongs to the rolling auxiliary equipment of metallurgy strip, particularly a kind of board rolling smashing machine.
Background technology
In the operation of rolling of Strip, the Strip of the rolling mistake of part need to be cut edge, and the limit section that scales off is called cutting edge, and cutting edge generally has two kinds of processing modes: a kind of is curling with crimping machine; Another kind is to be cut into segment with smashing machine.
Smashing machine mainly adopts the double drum type smashing machine at present, in the shear of double drum type smashing machine, upper cutter shaft and lower cutter shaft is arranged, and upper and lower cutter shaft is installed respectively shear blade, and the major parameter of this structure has up and down lap and the sideshake of shear blade.
From double drum type smashing machine operating position and research theme, be faced with at present common technological difficulties: to the control of shear blade sideshake.The shear blade sideshake is excessive up and down too smallly all can increase shearing force, causes the shear blade quick abrasion, even falls sword, collapses piece, reduces the shear blade life-span.
For the double drum type smashing machine, in order to control up and down shear blade sideshake, lower cutter shaft adopts the subdivision gear drive, simultaneously the high-precision bearing of transmission adopted; In order to adjust up and down shear blade sideshake, lower cutter shaft is provided with axial adjusting device.The said method cost is higher, and is difficult to accurate control and adjusts up and down shear blade sideshake.
The Wang Dingbao of Luoyang Industrial higher Junior College proposes cutter shaft under the smashing machine is not installed shear blade in " improvement of Leftover Bits and Pieces Crasher " literary composition, become optical axis, shear blade is directly contacted with lower cutterhead, so fundamentally eliminated the impact of shear blade sideshake.But in order to cut off Strip, shear blade and lower cutterhead must keep close contact, can make so the serious rigid shock of shear blade and lower cutterhead, damage shear blade and lower cutterhead.
Summary of the invention
The object of the present invention is to provide and a kind ofly can eliminate the defective that traditional smashing machine shear blade sideshake is brought, prevent the board rolling smashing machine that shear blade and lower cutterhead damage.
Technical scheme of the present invention is as follows:
The present invention mainly comprises frame, transmission system, shear and opening degree adjusting device, and wherein, transmission system mainly is comprised of drive motors, decelerator, power transmission shaft.Drive motors is located at an end of frame, and this drive motors is passed to power transmission shaft to power by decelerator; Two shear left-right symmetry, structure are identical, are located at respectively on the guide rail on the frame, and it mainly is comprised of casing, cutter shaft, compression spring, screw, shear blade, shear plate and gripper shoe.Cutter shaft is provided with internal spline, and above-mentioned power transmission shaft is provided with external splines, and cutter spindle sleeve consists of spline coupling on power transmission shaft, and the cutter shaft that above-mentioned power transmission shaft drives in two shears rotates, and power transmission shaft and cutter shaft can mutually move axially to adapt to the different openings degree and shear.Two relative ends of cutter shaft respectively are provided with 2-4 cutter groove, and 2-4 shear blade is installed in the cutter groove by screw and compression spring, and shear blade is helical edges.Gripper shoe is fixed on the casing, and it is corresponding with shear blade below cutter shaft, and this gripper shoe is provided with shear plate, and shear plate adopts the lower and wear-resisting material of hardness to avoid shear blade to damage.Drive cutter shaft by power transmission shaft in the work and rotate, shear blade periodically contacts with shear plate, realizes the cut-out to the Strip cutting edge, and the tightness degree that shear blade contacts with shear plate is also namely regulated the shearing force size by screw and compression spring adjustment.The opening degree device mainly is comprised of buncher and leading screw.Buncher is located at the other end of frame, and buncher drives leading screw and rotates, and the casing of above-mentioned shear is provided with screwed hole, and above-mentioned leading screw drives two shears by spiral marking connection and slides at the guide rail of frame, realizes the opening degree adjusting.
The present invention compared with prior art has following advantage:
1, the present invention only has upper cutter shaft to establish shear blade, compare with traditional scrap cutter device, do not have two sideshakes between shear blade, eliminated the problem that sideshake is brought, also needn't adopt the subdivision gear relevant with sideshake, high-precision bearing and axial adjusting device, reduce cost.
2, shear blade is installed in the cutter groove by screw and compression spring, and compression spring can reduce the rigid shock of shear blade and shear plate; Simultaneously screw and compression spring are used for controlling the tightness degree that contacts of shear blade and shear plate, and convenient to adjust shearing force big or small.
3, shear blade contacts with shear plate, and shear plate adopts the low and wear-resisting material of hardness, and shear blade is not fragile like this, and shear plate is difficult for producing tool marks.
4, compare with the transmission system of traditional smashing machine, only need cutter shaft is driven, omitted the driving parts such as all a plurality of gears, axle and bearing, simplified smashing machine.
