Abstract
The utility model relates to a blade holder locking mechanism under plate shearing machine. Including installing the lower blade holder in the frame top, be equipped with the bearing down between blade holder and the frame, the blade holder up end is equipped with the counter bore down, the bearing axial is equipped with the guiding hole, the guiding hole communicates with each other with the counter bore, be equipped with the guide post in the guiding hole, the guide post lower extreme is equipped with the connecting rod, the connecting rod lower extreme is connected with the piston rod of hydro -cylinder, the hydro -cylinder is installed in the frame, the guide post upper end is equipped with the clamp plate, the clamp plate is located the counter bore upper end. The utility model discloses simple structure, upper and lower blade cutting edge clearance adjustment is convenient, and the hydro -cylinder passes through connecting rod pulling clamp plate to firmly push down down the blade holder, thereby guaranteed the stability in upper and lower blade cutting edge clearance, when needing the adjustment bottom knife, loosen connecting rod drive clamp plate by the hydro -cylinder and loosen blade holder down, the convenient blade holder down that removes, it is swiftly convenient.
Description
Technical field
The utility model relates to tool rest retaining mechanism under a kind of plate shearing machine, 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.
When the upper and lower blade cutting edge gap of adjustment plate shearing machine, when adopting adjustment bottom knife, need mobile lower tool rest, and traditional lower tool rest locking mode adopts screw to lock, in the course of the work, of long duration, screw easily loosens, cause upper and lower blade cutting edge gap to change greatly, and carry out locking or loosening time dismantle cumbersome.
Utility model content
For above-mentioned defect, the purpose of this utility model is to provide a kind of structure simple, tool rest convenient disassembly under plate shearing machine, and locking firmly, ensures tool rest retaining mechanism under a kind of plate shearing machine that upper and lower blade cutting edge gap is stable.
The technical scheme that the utility model adopts for this reason is:
Comprise the lower tool rest be arranged on above frame, supporting base is provided with between described lower tool rest and frame, described lower tool rest upper surface is provided with counterbore, and described supporting base is axially arranged with pilot hole, and described pilot hole communicates with counterbore, lead is provided with in described pilot hole, described lead lower end is provided with connecting rod, and described connecting rod lower end is connected with the piston rod of oil cylinder, and described oil cylinder is arranged in frame, described lead upper end is provided with pressing plate, and described pressing plate is positioned at counterbore upper end.
Further, be provided with spring base below described supporting base, described spring base is arranged in frame, is provided with spring in described spring base, and described spring to be positioned at below lead and to be enclosed within connecting rod.
Further, the packing ring be enclosed within lead is provided with between described pressing plate lower surface and counterbore bottom surface.
The utility model has the advantages that:
The utility model structure is simple, and upper and lower blade cutting edge gap is easy to adjust, and oil cylinder pulls pressing plate by connecting rod, thus firmly pushes down lower tool rest, thus ensure that the stability in upper and lower blade cutting edge gap; When needing adjustment bottom knife, unclamp connecting rod by oil cylinder and drive tool rest under clamp loose, convenient mobile lower tool rest, efficient and convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1 be frame, 2 are lower tool rests, 3 are supporting bases, 4 are leads, 5 are connecting rods, 6 are oil cylinders, 7 are pressing plates, 8 are spring bases, 9 are springs, 10 is packing rings.
