Description
Technical field
The utility model relates to a kind of deburring scrap cutter.
Background technology
Trimming Die cuts after deburring the waste material got off larger time, be unfavorable for, outside waste material sliding Trimming Die, being also unfavorable for the collection of waste material, therefore comparatively large longer waste material needs to cut off.General Trimming Die adopts the cut-out completing deburring and waste material in a jig frequency, and after namely patrix deburring insert has coordinated deburring with deburring counterdie downwards, patrix deburring insert continues to have coordinated waste material to cut off with counterdie waste knife downwards; In order to eliminate patrix deburring insert and counterdie waste knife is interfered, step cutting edge must be set in patrix deburring insert, like this when deburring, can be formed at the interface point place of the step cutting edge of patrix deburring insert and tear the deburring such as breach, burr defect, affect the surface quality of part.
Summary of the invention
For the Trimming Die solving prior art completes the cut-out of deburring and waste material in a jig frequency, can be formed at the interface point place of trimming upper die step cutting edge and tear breach, the deburring defects such as burr, affect the problem of the surface quality of part, the utility model provides a kind of deburring scrap cutter, a kind of deburring scrap cutter of the present utility model comprises the floating cutter hub between the patrix deburring insert being contained in the right and left, to be contained on floating cutter hub and the spring be placed in upper bolster socket bore and stop screw, described stop screw is contained in step through-hole that floating cutter hub is opened and is spirally connected with upper bolster, the screw head of described stop screw is greater than the aperture of step through-hole.
Further, also comprise slide guide cover plate, described slide guide cover plate connects firmly at patrix deburring insert sidewall, and a part for slide guide cover plate covers on floating knife surface.
Further, also comprise safety cover plate, described safety cover plate connects firmly in patrix deburring insert, and a part for safety cover plate covers the step through-hole aperture that floating cutter hub is opened.
Described spring is nitrogen spring.
The utility model has following good effect compared to prior art, a kind of deburring scrap cutter of the present utility model, due to the position-limiting action of spring force and stop screw, make the patrix deburring insert deburring simultaneously of floating cutter hub and the right and left, can avoid like this being formed at the interface point place of trimming upper die step cutting edge tearing breach, the deburring defects such as burr, solve the problem affecting the surface quality of part, continue descending after floating cutter hub and patrix deburring insert complete deburring simultaneously more simultaneously, when floating cutter hub contact counterdie waste knife, spring starts to be compressed, after this patrix deburring insert continues descending, floating cutter hub and counterdie waste knife complete the cut-out to waste material.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the deburring of the patrix deburring insert of prior art and cuts off schematic diagram with the waste material of counterdie waste knife.
Fig. 2 is the schematic perspective view of a kind of deburring scrap cutter of the present utility model.
Fig. 3 is the schematic diagram of Fig. 2 B-B section.
In figure: 1. part, 1 '. waste material, 2. float cutter hub, 21. springs, 22. stop screws, 23. safety cover plates, 24. slide guide cover plate, 3. upper bolsters, 4. patrix deburring insert, 5. counterdie waste knife.
Detailed description of the invention
Fig. 1 is the deburring of the patrix deburring insert of prior art and cuts off schematic diagram with the waste material of counterdie waste knife.Waste material cut-out is completed in order to realize patrix deburring insert 4, eliminate patrix deburring insert 4 to interfere with counterdie waste knife 5, the cutting edge of patrix deburring insert 4 has made step, the cut-out of part 1 deburring and waste material 1 ' is completed in a jig frequency, namely patrix deburring insert 4 coordinates with deburring counterdie downwards, after completing part 1 deburring, patrix deburring insert 4 continues to have coordinated waste material 1 ' to cut off with counterdie waste knife 5 downwards, like this when deburring, part 1 can be formed at the interface point A place of step cutting edge and tear the deburring such as breach, burr defect, affects the surface quality of part 1.
Fig. 2 and Fig. 3 shows a kind of deburring scrap cutter of the present utility model, comprise the floating cutter hub 2 between the patrix deburring insert 4 being contained in the right and left, be contained on floating cutter hub 2 and the spring 21 be placed in upper bolster 3 socket bore and stop screw 22, described stop screw 22 is contained in step through-hole that floating cutter hub 2 is opened and is spirally connected with upper bolster 3, and the screw head of described stop screw 22 is greater than the aperture of step through-hole.
Further, also comprise slide guide cover plate 24, described slide guide cover plate 24 connects firmly at patrix deburring insert 4 sidewall, and a part for slide guide cover plate 24 covers floating cutter hub 2 on the surface, and the cutter hub 2 that floats like this slides up and down more steady.
Further, also comprise safety cover plate 23, described safety cover plate 23 connects firmly in patrix deburring insert 4, and a part for safety cover plate 23 covers the step through-hole aperture that floating cutter hub 2 is opened, like this when stop screw 22 failure fracture, can prevent floating cutter hub 2 to come off part of damage 1 and Trimming Die.
Described spring 21 is nitrogen springs.
The eccentric swage on Trimming Die and split punch is also show in Fig. 3, when upper bolster 3 starts to move downward, first part 1 is pressed on split punch by eccentric swage, after this upper bolster 3 continues descending, patrix deburring insert 4 moves downward with upper bolster 3 with floating cutter hub 2, the cutter hub 2 that floats completes deburring in the elastic force effect lower and upper die repair limit insert 4 of nitrogen spring simultaneously, continue descending after floating cutter hub 2 and patrix deburring insert 4 complete deburring, the cutter hub 2 that floats contacts with counterdie waste knife 5, the cutter hub 2 that now floats is no longer descending, above it, nitrogen spring starts compression, patrix deburring insert 4 continues the descending cut-out completing waste material 1 '.
