Abstract
The utility model relates to a plate shearing machine blade clearance adjustment mechanism. Including the gear motor who installs in frame one side, the lead screw that is connected with the gear motor output and rack -mounted under the blade holder, lead screw both ends cover has the nut, blade holder lower extreme fixed mounting has two fixed sloping blocks down, every nut overlaps respectively outward has the sloping block, sloping block and fixed sloping block in close contact with, cooperate with rack -mounted rest pad in the level side of sloping block. The utility model discloses simple structure drives the lead screw, lead screw push -and -pull nut, removal about nut drive sloping block through gear motor to the fine motion of blade holder and bottom knife under realizing by the fixed sloping block of sloping block promotion, the while ensures to fix the sloping block by pressure spring's thrust effect and the sloping block keeps in close contact with's state constantly, thus the convenience is adjusted, long service life to the purpose of blade cutting edge clearance fine setting about reaching.
Description
Technical field
The utility model relates to a kind of blade clearance of plate-shearing machine guiding mechanism, belongs to plate shearing machine equipment technical field.
Background technology
Plate shearing machine is used for the shearing of sheet metal, the shearing power resources of plate shearing machine are in hydraulic drive or machine driving, during shear, according to the gap between the thickness adjustment cutter cutting edge of the shear strength and sheet metal that are sheared sheet metal and bottom knife cutting edge, and must to keep the uniformity in gap.Sheet metal is thicker, shear strength is higher, and the gap between cutter cutting edge and bottom knife cutting edge is larger.When sheet metal sheared by plate shearing machine, sheet metal front end is sent to the backgauge origin reference location of plate shearing machine, then material pressing device pushes down the sheet metal on rear side of bottom knife cutting edge, and the cutter cutting edge then tilted is descending progressively shears the sheet metal be positioned on front side of bottom knife cutting edge.When cutter cutting edge and bottom knife cutting edge exceed its shear strength to the extruding force up and down that sheet metal applies, sheet metal is cut off.Owing to there is gap between cutter cutting edge and bottom knife cutting edge, the shear plane of sheet metal is also not orthogonal to plate surface, and the shearing force of cutting off sheet metal moment certainly leads to horizontal component.
The upper and lower blade clearance adjusting device of existing all kinds of plate shearing machine adopts adjustment cutter to realize the adjustment of upper and lower gap blade substantially, also have and adopt hand adjustment bottom knife, then by clearance gauge manual measurement, but the method is accurate not, and need workman to enter in lathe to measure, security is lower.
Utility model content
For above-mentioned defect, it is simple that the purpose of this utility model is to provide a kind of structure, and easy to operate, upper and lower blade cutting edge gap is easy to adjust, a kind of blade clearance of plate-shearing machine guiding mechanism of long service life.
The technical scheme that the utility model adopts for this reason is:
Comprise the reducing motor being arranged on frame side, the screw mandrel be connected with reducing motor output and rack-mounted lower tool rest, described screw mandrel two ends cover has nut, described lower tool rest lower end is installed with two fixing skewbacks, described each nut overlaps outward respectively skewback, described skewback and fixing skewback close contact, the horizontal side of described skewback matches with rack-mounted rest pad.
Further, the horizontal side of described fixing skewback is provided with holddown spring, and the other end of described holddown spring props up the baffle plate be fixedly mounted in frame.
Further, described frame is provided with linear displacement transducer, the contact of described linear displacement transducer is connected with skewback.
The utility model has the advantages that:
The utility model structure is simple, screw mandrel is driven by reducing motor, screw mandrel push-and-pull nut, nut drives skewback to move left and right, thus the fine motion of lower tool rest and bottom knife is realized by the fixing skewback of skewback promotion, guaranteed the state of fixing skewback and skewback moment maintenance close contact simultaneously by the thrust of holddown spring, thus reach the object of upper and lower blade cutting edge clearance fine adjustment, easy to adjust, long service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1 be frame, 2 are reducing motors, 3 are screw mandrels, 4 are lower tool rests, 5 are nuts, 6 are fixing skewbacks, 7 are skewbacks, 8 are rest pads, 9 are holddown springs, 10 are baffle plates, 11 is linear displacement transducers.
Detailed description of the invention
A kind of blade clearance of plate-shearing machine guiding mechanism, the lower tool rest 4 comprising the reducing motor 2 being arranged on frame 1 side, the screw mandrel 3 be connected with reducing motor 2 output and be arranged in frame 1, described screw mandrel 3 two ends cover has nut 5, described lower tool rest 4 lower end is installed with two fixing skewbacks 6, the outer cover respectively of described each nut 5 has skewback 7, described skewback 7 and fixing skewback 6 close contact, the horizontal side of described skewback 7 matches with the rest pad 8 be arranged in frame 1; The horizontal side of described fixing skewback 6 is provided with holddown spring 9, and the other end of described holddown spring 9 props up the baffle plate 10 be fixedly mounted in frame 1; Described frame 1 is provided with linear displacement transducer 11, and the contact of described linear displacement transducer 11 is connected with skewback 7.
Screw mandrel 3 is driven by reducing motor 2, screw mandrel 3 push-and-pull nut 5, nut 5 drives skewback 7 to move left and right, thus promote by skewback 7 fine motion that fixing skewback 6 realizes lower tool rest 4 and bottom knife, guaranteed the state of fixing skewback 6 and skewback 7 moment maintenance close contact simultaneously by the thrust of holddown spring 9, thus reach the object of upper and lower blade cutting edge clearance fine adjustment.
