Abstract
A shearing mechanism of a scrap slitting shear for metal plates comprises a framework, an upper shear shaft and a lower shear shaft. The upper shear shaft and the lower shear shaft which are rotatable are disposed on the framework, one end of the upper shear shaft and one end of the lower shear shaft are provided with gears meshed with each other, the upper shear shaft is provided with a shear blade mounting groove, a shear blade is arranged in the shear blade mounting groove, and the lower shear shaft is a smooth shaft in surface hardening treatment. The shearing mechanism not only avoids dislocation of the shear blade, increases production efficiency and is long in service life, an upper shear blade groove and a key groove of the upper shear shaft do not have severe relative position requirements, indexing of the meshed gears and hole key grooves of the meshed gears do not have severe relative position requirements either, and accordingly manufacturing cost is reduced.
Description
Technical field
The utility model relates to a kind of metallic plate cropping cut field, a kind of specifically metal
The cutting mechanism of the broken limit of plate slitting.
Background technology
Cutting mechanism is one of indispensable key mechanism in the slitting of broken limit, and its function is that the material limit that circle shear is cut is cut into broken section, so that collect and melting.From the cutting mechanism structure of 650 broken limit slittings of U.S. DELTA company import, it is cut up and down all cutting edge on the axle, and there is certain defective in this structure:
Cutting edge, cut axle, the accuracy of gear and require highly, make difficulty, the cost height.In the process of broken limit, upper scissor blade must be aimed at lower scissor blade arc surface center and be only perfect condition.This just requires to cut up and down between a upper scissor blade groove and the keyway, strict positional precision is all arranged, the cost of manufacture costliness between the calibration of gear teeth and its hole keyway.
2. lower scissor blade wearing and tearing back reuses the cost height.Because of lower scissor blade is an arc surface, wearing and tearing need install to grinding on the special grinding apparatus after scratching.
3. cutting edge is often right because of vibrations dislocation parking accent, and influence is produced.Because smashing machine when work, the power that acts on the cutting edge is impact, make to cut axle and produce vibrations, particularly when working gear a period of time of after, all there are wearing and tearing in various degree on the working gear surface, this has more aggravated the vibrations of cropping cut mechanism.The bearing block loam cake screw of cutting a two ends often becomes flexible, comes off under such condition of work, and meshing gear breaks away from, on cut a rotating speed and lag behind, at this moment cutting edge dislocation and can't cut off the material limit must stop and transfer cutting edge, has a strong impact on production.
The utility model content
The purpose of this utility model is to be the deficiency that solves the problems of the technologies described above, and the cutting mechanism of the broken limit of a kind of metallic plate slitting is provided, long service life not only, and improved production efficiency, reduced cost.
The utility model is the deficiency that solves the problems of the technologies described above, the technical scheme that is adopted is: the cutting mechanism of the broken limit of a kind of metallic plate slitting, comprise frame, be arranged on cut on rotating on the frame axle and under cut axle, be provided with pitch wheel at the last axle of cutting with an end of cutting axle down, cut axle on described and be provided with the cutting edge mounting groove, cutting edge is arranged in the cutting edge mounting groove, the described optical axis of axle for the surface hardening processing of cutting down.
Described cutting edge is arranged in the cutting edge mounting groove by pressing plate.
The beneficial effects of the utility model are:
This mechanism had both avoided the cutting edge inconsistent phenomenon, had improved production efficiency, and long service life, on cut between a upper scissor blade groove and the keyway, do not have strict relative position requirement between the calibration of meshing gear and its hole keyway, reduced manufacturing cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is along the cutaway view of A-A line among Fig. 1.
Mark among the figure: 1, frame, 2, on cut axle, 3, cut axle down, 4, gear, 5, the cutting edge mounting groove, 6, cutting edge, 7, pressing plate, 8, hardened layer.
The specific embodiment
As depicted in figs. 1 and 2, the cutting mechanism of the broken limit of a kind of metallic plate slitting, comprise frame, be arranged on cut on rotating on the frame axle and under cut axle, be provided with pitch wheel at the last axle of cutting with an end of cutting axle down, guarantee rotation synchronously under the driven by motor, cut axle on described and be provided with the cutting edge mounting groove, cutting edge is arranged in the cutting edge mounting groove, the described optical axis of axle for the surface hardening processing of cutting down.
Described cutting edge is arranged in the cutting edge mounting groove by pressing plate, and by screw pressing plate is fixed.
The utility model, cut axle under described and can select 40Cr for use, HB is 256-285 after the modifier treatment, HRC is 45-50 after the surface hardening, the thin hardened layer that the surface forms is 3-4mm, makes piece surface obtain higher hardness and heart portion still keeps certain toughness, and part promptly has certain wearability and can withstand shocks again, and under can reuse through the grinding cylindrical after cutting axle wearing and tearing
The utility model had both been avoided the cutting edge inconsistent phenomenon, had improved production efficiency, and long service life, on cut between a upper scissor blade groove and the keyway, do not have strict relative position requirement between the calibration of meshing gear and its hole keyway, reduced manufacturing cost.
