Description
Technical field
This utility model relates to a kind of punch process field, particularly relates to the diel of a kind of band reverse extrusion.
Background technology
Punching processing is to drive punch upper die down to move by stamping machine, mutual extrded material under the effect of punching lower mold, thus complete punching processing, aperture can be caused to have downward burr during due to upper mold extrded material, thus affect the outward appearance of part, and the finger of burr easy scratch workman, in view of disadvantages described above, it is necessary to design the diel of a kind of band reverse extrusion in fact.
Summary of the invention
Technical problem to be solved in the utility model is: provide the diel of a kind of band reverse extrusion, the problem that can cause hole bur after solving punching processing.
nullFor solving above-mentioned technical problem，The technical solution of the utility model is: the diel of a kind of band reverse extrusion，Including lower bolster、Die shoe、Die、Hydraulic cylinder、Extrusion die、Upper bolster、Drift、Pressing plate、Spring，Described die shoe is positioned at lower bolster top，Described die shoe is connected with lower bolster screw thread，Described die is positioned at die shoe inner upper end，Described die is connected with die shoe close-fitting，Described hydraulic cylinder is positioned at lower bolster top，And described hydraulic cylinder is positioned at inside die shoe，Described hydraulic cylinder is connected with lower bolster screw thread，Described extrusion die is positioned at hydraulic cylinder top，Described extrusion die is connected with hydraulic cylinder close-fitting，Described upper bolster is positioned at die shoe upper end，Described drift runs through upper bolster，Described drift is connected with upper bolster screw thread，Described pressing plate is through drift lower end，Join sliding with drift of described pressing plate is connected，Described spring is through drift lower end，And described spring is between pressing plate and upper bolster，Described spring is connected with upper bolster and pressing plate screw thread.
Further, described die shoe right-hand member is additionally provided with air valve, and described air valve is connected with die shoe screw thread.
Further, described air valve left end is additionally provided with valve, and described valve runs through die shoe right-hand member, and described valve is connected with air valve and die shoe close-fitting.
Further, described die shoe front end also sets chip-removal hole.
nullCompared with prior art，The diel of this band reverse extrusion，First pass through lower bolster and upper bolster this diel to be arranged on hydraulic press，Punching parts is placed on the upper end of die，Start hydraulic press，Upper bolster is down moved together with drift，First by pressing plate by Work-sheet pressing in die upper end，And extrusion spring，Drift is ejected from pressing plate and continues down to move，Die coordinate under thus punching processing can be completed，After punching completes，Hydraulic press drives upper bolster up to move，Start hydraulic cylinder simultaneously，And the moment up moved at upper bolster，Drift followed by upper bolster and the most up moves，Under the down thrust of spring，Make pressing plate still by Work-sheet pressing，Therefore up can be moved by Hydraulic Cylinder extrusion die，Thus burr downward for aperture up can be extruded，Therefore the burr in aperture can be squeezed，And least a portion of burr is extruded to inside hole，Thereby ensure that accessory appearance，And burr scratch staff can be avoided.

Lower bolster 1, die shoe 2, die 3, hydraulic cylinder 4, extrusion die 5, upper bolster 6, drift 7, pressing plate 8, spring 9, air valve 201, nozzle 202, chip-removal hole 203.
Following detailed description of the invention will further illustrate in conjunction with above-mentioned accompanying drawing.
Detailed description of the invention
Hereinafter, multiple specific detail is elaborated, in order to provide the thorough understanding to the concept constituting described embodiment basis.But, it will be apparent to those skilled in the art that described embodiment can be put into practice in the case of some or all in not having these specific detail.In other cases, well-known process step is not specifically described.
nullSuch as Fig. 1、Fig. 2、Shown in Fig. 3，A kind of diel of band reverse extrusion，Including lower bolster 1、Die shoe 2、Die 3、Hydraulic cylinder 4、Extrusion die 5、Upper bolster 6、Drift 7、Pressing plate 8、Spring 9、Air valve 201、Nozzle 202、Chip-removal hole 203，Described die shoe 2 is positioned at lower bolster 1 top，Described die shoe 2 is connected with lower bolster 1 screw thread，Described die 3 is positioned at die shoe 2 inner upper end，Described die 3 is connected with die shoe 2 close-fitting，Described hydraulic cylinder 4 is positioned at lower bolster 1 top，And described hydraulic cylinder 4 is positioned at die shoe 2 inside，Described hydraulic cylinder 4 is connected with lower bolster 1 screw thread，Described extrusion die 5 is positioned at hydraulic cylinder 4 top，Described extrusion die 5 is connected with hydraulic cylinder 4 close-fitting，Described upper bolster 6 is positioned at die shoe 2 upper end，Described drift 7 runs through upper bolster 6，Described drift 7 is connected with upper bolster 6 screw thread，Described pressing plate 8 is through drift 7 lower end，Join sliding with drift 7 of described pressing plate 8 is connected，Described spring 9 is through drift 7 lower end，And described spring 9 is between pressure 8 plates and upper bolster 6，Described spring 9 is connected with upper bolster 6 and pressing plate 8 screw thread，Described die shoe 2 right-hand member is additionally provided with air valve 201，Described air valve 201 is connected with die shoe 2 screw thread，Described air valve 201 left end is additionally provided with valve 202，And described valve 202 runs through die shoe 2 right-hand member，Described valve 202 is connected with air valve 201 and die shoe 2 close-fitting，Described die shoe 2 front end also sets chip-removal hole 203，The diel of this band reverse extrusion，First pass through lower bolster 1 and this diel is arranged on hydraulic press by upper bolster 6，Punching parts is placed on the upper end of die 3，Start hydraulic press，Upper bolster 6 is down moved together with drift 7，First by pressing plate 8 by Work-sheet pressing in die 3 upper end，And extrusion spring 9，Drift 7 is made 8 plates to eject and continue down to move from pressing，Die 3 coordinate under thus punching processing can be completed，After punching completes，Hydraulic press drives upper bolster 6 up to move，Start hydraulic cylinder 4 simultaneously，And the moment up moved at upper bolster 6，Drift 7 followed by upper bolster 6 and the most up moves，Under the down thrust of spring 9，Make pressing plate 8 still by Work-sheet pressing，Therefore extrusion die 5 can be promoted up to move by hydraulic cylinder 4，Thus burr downward for aperture up can be extruded，Therefore the burr in aperture can be squeezed，And least a portion of burr is extruded to inside hole，Thereby ensure that accessory appearance，And burr scratch staff can be avoided，When punching processing，Can be connected with air feed equipment by air valve 201，Thus valve 202 can be controlled by air valve 201 and ventilate，Therefore when punching processing，Valve 202 can be to extrusion die 5 jet，Thus can by punching time the defective material in extrusion die 5 upper end that drops blow off，Chip-removal hole 203 is easy for discharging the defective material produced after punching.
