The shearing mechanism can eliminate the defect caused by lateral clearance, reduces the rigid impact between the shearing blades and the shearing plates, and prevents the shearing blades and a lower cutter disk from damage.
Description
Technical field
The utility model 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 material, the strip material of the rolling mistake of part need be cut edge, and the limit portion that scales off is called cutting edge, and cutting edge generally has two kinds of processing modes: a kind of is to curl 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, last cutter shaft and following cutter shaft is arranged, and upper and lower cutter shaft is installed shear blade respectively, and the major parameter of this structure has lap and the sideshake of shear blade up and down.
From double drum type smashing machine operating position and research theme, be faced with common technological difficulties at present: 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 shear blade sideshake up and down, following cutter shaft adopts the subdivision gear drive, simultaneously the high-precision bearing of transmission adopted; In order to adjust shear blade sideshake up and down, following cutter shaft is provided with axial adjusting device.The said method cost is higher, and is difficult to accurate control and adjusts shear blade sideshake up and down.
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 following cutterhead, so fundamentally eliminated the influence of shear blade sideshake.But in order to cut off the strip material, shear blade must keep tight the contact with following cutterhead, can make the serious rigid shock of shear blade and following cutterhead like this, damages shear blade and following cutterhead.
The utility model content
The purpose of this utility model is to provide a kind of can eliminate the defective that traditional smashing machine shear blade sideshake is brought, and prevents the board rolling smashing machine that shear blade and following cutterhead damage.
The technical solution of the utility model is as follows:
The utility model mainly comprises frame, transmission system, shear and opening degree adjusting device, and wherein, transmission system mainly is made up 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 made up 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 constitutes spline and connects 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 move axially to adapt to the different openings degree mutually 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 low and wear-resisting material of hardness to damage to avoid shear blade.Drive cutter shaft by power transmission shaft in the work and rotate, shear blade periodically contacts with shear plate, realizes the cut-out to strip material 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 adjusting device mainly is made up 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 utility model compared with prior art has following advantage:
1, the utility model has only last cutter shaft to establish shear blade, compare with traditional scrap cutter device, there are not 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, convenient adjustment shearing force size.
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 driving parts such as all a plurality of gears, axle and bearing, simplified smashing machine.
