Description
Technical field
The present invention relates to the tool rest processing technique field, more particularly, relate to a kind of tool rest processing method that carries locking device.
Background technology
The sheet metal banding machine relies on the roller shear cutter to roll at sheet material, finishes the endless shear action to sheet material.The sheet metal banding machine is used for vertical roller shear of common metal sheet material, aluminium sheet, corrosion resistant plate, silicon steel plate etc.The roller shear cutter is widely used in industries such as space flight and aviation, automobile making, mining machinery, five metals manufacturing, household electrical appliances.When cutting, the rotation of roller shear cutter relies on the tool rest that is locked on the cutter shaft to drive.Tool rest can be fastened on the cutter shaft and tool rest fastening after whether beat be directly connected to the quality of shearing the back material.Generally speaking, tool rest is fastened on the cutter shaft, when the end face run-out of detection tool rest surpasses 0.01mm, will cause the overlapping collision of discontinuity mutually in the high speed rotary course of upper and lower blade, causes the blade chipping.
In the existing tool rest production technology, the locking of tool rest relies on the pin key locking that is assemblied on the cutter shaft, as shown in Figure 1, in addition, China Patent No. ZL201020050405.3, Granted publication day is on November 24th, 2010, invention and created name is: the two key roller shear cuttves of carbide alloy, this application case comprises cutter hub, and described cutter hub is loop configuration, and the outer ring of cutter hub is blade, the central authorities of cutter hub are the circular mounting hole, the inner ring of cutter hub is provided with the R key of indent, and the R key of indent has two, is symmetrically distributed on the inner ring of cutter hub.In addition, China Patent No. ZL201120162794.3, Granted publication day is on January 25th, 2012, invention and created name is: the roller shear cutter, the blade that this application case comprises tool matrix and is engaged in the tool matrix periphery is provided with the keeper that prevents that blade from coming off between tool matrix and blade.The technical scheme of the tool rest that prior art is commonly used and two above-mentioned patents all adopts the mode of pin key locking, and its weak point is to be difficult to tool rest is fastened on the cutter shaft, causes the end face run-out value of tool rest bigger, and it is low to cut precision.
For guarantee that tool rest does not produce beat after assembling as far as possible, the general method of the fit clearance of dwindling tool rest endoporus and cutter shaft that adopts of cutter manufacturer is finished, but, when the fit clearance of tool rest endoporus and cutter shaft is reduced into 0 ~ 0.02mm, will causes and be difficult to assembling and dismounting between the two.And after adopting this method that tool rest is locked at cutter shaft, the tool rest end face run-out is difficult to control within 0.01mm, cause the roller shear blade when cutting, easily to cause upper and lower cutter in the disconnected property collision of high speed rotational time, influence the service life of roller shear cutter, and can't realize cutting the requirement of high-precision metal sheet material.
By patent retrieval, existing related art scheme is open in the prior art.As, China Patent No. ZL91220590.3, Granted publication day is on April 22nd, 1992, invention and created name is: the closed roller shear cutter that suppresses, this application case relate to a kind of closed roller shear cutter that suppresses, and mainly are made of cutter hub and blade two big parts, slit at one group of hole of cutter hub processing and connect apertures, make cutter hub itself directly form elastic press, by to the elastic press application of force, play that the roller shear cutter is fastened to effect on the cutter shaft.This roller shear cutter has improved machining accuracy to a certain extent, but only adopted the slit to make up the mode of elastic press, made tool rest end face run-out value be difficult to control steady in a long-term in 0.01mm, machining accuracy is still lower, remain further to be improved, and its processing method is still undocumented.
