Abstract
Disclosed is a scrap chopper for plate and strip rolling. A drive motor is disposed at one end of a frame and transmits power to a drive shaft through a reducer. 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 auxiliary equipment of metallurgy strip rolling, particularly a kind of board rolling smashing machine.
Technical background
In the operation of rolling of Strip, the Strip of part rolling needs to carry out trimming, and the edge scaled off is called cutting edge, and cutting edge generally has two kinds of processing modes: one is curling with crimping machine; Another kind is cut into segment with smashing machine.
Current smashing machine mainly adopts double drum type smashing machine, and in the shear of double drum type smashing machine, have upper cutter shaft and lower cutter shaft, upper and lower cutter shaft installs shear blade respectively, and the major parameter of this structure has lap and the sideshake of upper and lower shear blade.
From double drum type smashing machine service condition and research theme, be faced with common technological difficulties at present: to the control of shear blade sideshake.Upper and lower shear blade sideshake is excessive too smallly all can increase shearing force, causes shear blade quick abrasion, even falls sword, collapses block, reduces the shear blade life-span.
For double drum type smashing machine, in order to control upper and lower shear blade sideshake, lower cutter shaft adopts subdivision gear drive, and transmission system adopts high-precision bearing simultaneously; In order to adjust upper and lower shear blade sideshake, lower cutter shaft is provided with axial adjusting device.Said method cost is higher, and is difficult to the upper and lower shear blade sideshake of accurate controlling and adjustment.
The Wang Dingbao of Luoyang Industrial higher Junior College proposes cutter shaft under smashing machine not install 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 eliminates the impact of shear blade sideshake.But in order to cut off Strip, shear blade and lower cutterhead must keep close contact, shear blade and the serious rigid shock of lower cutterhead can be made like this, damage shear blade and lower cutterhead.
Summary of the invention
The object of the present invention is to provide a kind of defect can eliminated traditional smashing machine shear blade sideshake and bring, 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 comprises drive motors, decelerator and power transmission shaft.Drive motors is located at one end of frame, and this drive motors passes to power transmission shaft by decelerator power; Two shear is symmetrical, structure is identical, and be located on the guide rail in frame respectively, it comprises casing, cutter shaft, compression spring, screw, shear blade, shear plate and gripper shoe.Cutter shaft is provided with internal spline, above-mentioned power transmission shaft is through two shears, power transmission shaft is provided with external splines, cutter spindle sleeve is on power transmission shaft, form spline coupling, above-mentioned power transmission shaft drives the cutter shaft in two shears to rotate, and power transmission shaft and cutter shaft mutually can move axially to adapt to different openings degree and shear.One end that two cutter shafts are relative is respectively provided with 2-4 cutter groove, and 2-4 shear blade is arranged in cutter groove by screw and compression spring, and shear blade is helical edges.Gripper shoe is fixed on casing, and it is corresponding with shear blade below cutter shaft, and this gripper shoe is provided with copper shear plate, and shear plate adopts the lower and wear-resisting material of hardness to damage to avoid shear blade.Drive cutter shaft to rotate by power transmission shaft in work, shear blade and shear plate periodic contact, realize the cut-out to Strip cutting edge, and the tightness degree that shear blade contacts with shear plate is adjusted by screw and compression spring, also namely regulates shearing force size.Opening degree adjusting device comprises buncher and becomes with leading screw.Buncher is located at the other end of frame, and buncher drives screw turns, and the casing of above-mentioned shear is provided with screwed hole, and above-mentioned leading screw drives two shears at the slide on rails of frame by spiral marking connection, realizes opening degree and regulates.
The present invention compared with prior art tool has the following advantages:
1, the present invention only has upper cutter shaft to establish shear blade, compared with traditional scrap cutter device, there is not the sideshake between two shear blade, eliminate the problem that sideshake is brought, also need not adopt the subdivision gear relevant to sideshake, high-precision bearing and axial adjusting device, reduce cost.
2, shear blade is arranged in cutter groove by screw and compression spring, and compression spring can reduce the rigid shock of shear blade and shear plate; What simultaneously screw and compression spring were used for controlling shear blade and shear plate contacts tightness degree, conveniently adjusts shearing force size.
3, shear blade contacts with shear plate, the material that shear plate adopts hardness low and wear-resisting, and such shear blade is not fragile, and shear plate not easily produces tool marks.
4, compared with the transmission system of traditional smashing machine, only need drive cutter shaft, eliminate the driving parts such as all multiple gears, axle and bearing, simplify smashing machine.
