Description
Technical field
The present invention relates to a kind of machining punching die, relate in particular to a kind of punch die that rushes breach for the edge of work; The invention still further relates to a kind of punching and cut processing method.
Background technology
As shown in Figure 1, workpiece 5 need be opened at the edge of workpiece half bar hole breach 10, to thin plate or the low intensive material that easily rushes, can adopt punch machining process, and its work efficiency is higher.The processing technology of general thick blanks edge gap has two kinds: the one, use the machine-tooled methods such as milling or line cutting, and the method production cost is high, efficiency is low; The 2nd, the technique of use sheet metal blanking, but when the thickness of steel workpieces reaches 10mm when above, when rushing breach, guide pillar guide pin bushing need to be installed on mould, and drift installation auxiliary device fractures avoiding, though the method production efficiency is high, but mould is more complicated, punch die easily damages, and cost is higher, and practicality is industrially not strong.
Summary of the invention
On the one hand, technical problem to be solved by this invention is to provide and a kind ofly has that production efficiency is high, mould is simple, the punch die of drift long service life.
Inventor finds after research: for the larger steel workpieces edge punching of thickness, punch die holds one of flimsy reason and is that drift rushes while expecting, the breach that cause is gone out is the edge at workpiece, the position of drift blanking is stressed large, the position that does not contact workpiece is stressed little, there is unbalance stress, cause generation to make the radial load of drift offset axis, thereby drift is easily damaged.
In order to solve the problems of the technologies described above, punching provided by the invention lacks one of punch die technical scheme: described punching lacks punch die and comprises upper bolster; Die shoe; Be connected to the drift on described upper bolster; Be connected to the counterdie on described die shoe; One side of described drift head has the locating dowel of the cutting edge portion of protruding drift, described counterdie has the hole coordinating with described drift, the protrusion height of described locating dowel is higher than the thickness of to be processed, locating dowel is inserted into behind the hole that described counterdie coordinates with drift, and the cutting edge portion of drift just rushes cuts to be processed.
In order to solve the problems of the technologies described above, punching provided by the invention lacks two of punch die technical scheme: described punching lacks punch die, comprises upper bolster; Die shoe; Be connected to the drift on described upper bolster; Be connected to the counterdie on described die shoe; The location-plate being connected with described die shoe; One side of described drift head has the locating dowel of the cutting edge portion of protruding drift, described counterdie has the hole coordinating with drift, described location-plate has the guide groove inserting for described locating dowel, and described locating dowel is at least inserted into after the guide groove of described location-plate, and the cutting edge portion of drift just rushes cuts to be processed.
Inventor also finds after research: in the larger steel workpieces edge punching of thickness, punch die holds one of flimsy reason and is: during drift punching material, the breach that cause is gone out is the edge at workpiece, relative breach one side of workpiece is in the effect of impulsive force, sometimes on existing, scratch phenomenon, be easier to generation and make the radial load of drift offset axis, thereby drift is easily damaged.
In order to solve the problems of the technologies described above, punching provided by the invention lacks punch die and improves one of technical scheme: on the basis of aforementioned techniques scheme one or 2, punching provided by the invention lacks punch die, also have at least one be connected with described upper bolster there is flexible stock pressing rod.
As optimal technical scheme, punching provided by the invention lacks punch die, and described stock pressing rod is polyurethane pressure material rod, and quantity is two.
During work, upper bolster drives drift undershoot, the guide groove that first locating dowel of the cutting edge portion of protrusion drift enters location-plate is or/and in the hole that counterdie coordinates with described drift, during drift punching material, the position of blanking is stressed large, and the position that does not contact workpiece is stressed little, cause drift to be subject to making it the radial load of offset axis, and first enter the guide groove of location-plate or/and the locating dowel in counterdie makes drift be subject to a reverse support force, can avoid fractureing of drift.Drift is completely descending, goes out breach, and material beans are discharged.Drift backhaul, takes out workpiece, and stamping-out completes.
Further in improvement project, the guide groove that enters location-plate in locating dowel is or/and the Kong Zhonghou that counterdie coordinates with described drift, and stock pressing rod is pushed down after workpiece, and drift is expected under continuing in a state of excitement again.
On the other hand, technical problem to be solved by this invention is to provide and a kind ofly has that production efficiency is high, rushing of drift long service life cut processing method.
In order to solve the problems of the technologies described above, one of processing method technical scheme is cut in punching provided by the invention: described punching is cut processing method and adopted the scarce punch die punching of a kind of punching to cut, and described punching lacks punch die and comprises upper bolster; Die shoe; Be connected to the drift on described upper bolster; Be connected to the counterdie on described die shoe, one side of described drift head has the locating dowel of the cutting edge portion of protruding drift, described counterdie has the hole coordinating with described drift, the protrusion height of described locating dowel is higher than the thickness of to be processed, punching is cut to add and is comprised following process man-hour: upper bolster and drift move to die shoe direction, locating dowel is inserted into behind the hole that described counterdie coordinates with drift, and the cutting edge portion of drift just rushes cuts to be processed.
Two of processing method technical scheme is cut in punching provided by the invention: described punching is cut processing method and adopted the scarce punch die punching of a kind of punching to cut, and described punching lacks punch die and comprises upper bolster; Die shoe; Be connected to the drift on described upper bolster; Be connected to the counterdie on described die shoe; The location-plate being connected with described die shoe, one side of described drift head has the locating dowel of the cutting edge portion of protruding drift, described counterdie has the hole coordinating with drift, described location-plate has the guide groove inserting for described locating dowel, punching is cut to add and is comprised following process man-hour: upper bolster and drift move to die shoe direction, locating dowel is at least inserted into after the guide groove of described location-plate, and the cutting edge portion of drift just rushes cuts to be processed.
One of process modifications technical scheme is cut in punching provided by the invention: described punching lack punch die also have at least one be connected with described upper bolster there is flexible stock pressing rod; punching is cut and is added man-hour; stock pressing rod is pushed down after to be processed, and the cutting edge portion of drift just rushes cuts to be processed.
The invention has the beneficial effects as follows: punching provided by the invention lacks punch die, during drift punching material, the guide groove that first locating dowel of the cutting edge portion of protrusion drift enters location-plate is or/and in the hole that counterdie coordinates with described drift, make drift be subject to a reverse support force, when drift is subject to making it the radial load of offset axis, can avoid fractureing of drift, increase the service life, improve the quality of products.
