Description
Technical field
The utility model belongs to Cold Press Working field, is related to a kind of punching while removing the mould of flash removed, more particularly to
A kind of punching on sheet material particularly sheet metal removes the mould of flash removed simultaneously.
Background technology
Diel, is that in Cold Press Working, material (metal is nonmetallic) is processed into part (or semi-finished product)
A kind of special process equipment.Metal material is under the effect of concave-convex mold shearing, from elastic deformation to plastic deformation again to fracture
Separation.Due to the presence of clearance between punch and die, lead to when metal material is pulled off in detaching direction beyond the flash part of sheet thickness
It is commonly referred to as burr (burr).The presence of burr directly influences the quality of product, so recent years is as every profession and trade is to hair
The attention removed is pierced, the method for deburring also emerges in an endless stream.Existing frequently-used burr removing method mainly has manual deburring, chemistry
Deburring, electrochemical deburring, ultrasonic wave deburring, thermal explosion deburring etc., these methods be all after the completion of Product processing
Secondary operation removal is carried out, is wasted time and energy.
The content of the invention
For the deficiencies in the prior art, the utility model provides a kind of mould for being punched and removing flash removed simultaneously, energy
Enough generations that burr is reduced in punching course, effective reduction personnel are artificial, improve the efficiency of stamping press, greatly improve
Productivity ratio.
In order to solve the above-mentioned technical problem, the utility model is achieved through the following technical solutions：
Punching goes integral on the mould of flash removed, including cavity plate and punch-pin, the cutting edge of cavity plate material-dropping hole be provided with simultaneously
Shape and the trapezoidal convex edge of material-dropping hole profile identical, the top surface of the trapezoidal convex edge is parallel to cutting edge top surface, described trapezoidal convex edge
Interior facade be located on the same line with material-dropping hole side wall.
Described punch-pin is shape of cross section and material-dropping hole profile identical cylinder.
Reasonable clearance (difference of the size of working portion between blanking punch and cavity plate) between described punch-pin and cavity plate
For the 10%~16% of thickness of slab.
Described trapezoidal convex edge is right-angled trapezium in the section of vertical direction.
The top margin length of described right-angled trapezium is 0.1~0.15mm, and base length is 1.1~1.15mm, the right angle length of side
Spend for 0.1~0.2mm.
Described trapezoidal convex edge is made into integration with cavity plate.
The utility model punching goes the mould of flash removed to be applied to the template material that thickness is 1~2mm simultaneously.
Relative to prior art, the beneficial effects of the utility model are：
(1) the utility model processes a trapezoidal convex edge on the cavity plate of mould, and this trapezoidal convex edge is in sheet during punching
Face first extrudes one and workpiece profile identical impression, then separates again so that the edge after punching is neat, reduces burr
Produce；
(2) the utility model is improved existing mold, and the function of deburring is added in blanking process, is shortened
Workpiece overall process time, improve production efficiency；
(3) the trapezoidal convex edge on the utility model cavity plate is made into integration with cavity plate, makes simple, with low cost.
Brief description of the drawings
Fig. 1 is the structural representation for the cavity plate that the utility model is punched the mould for removing flash removed simultaneously；
Fig. 2 be Fig. 1 in A-A to sectional view；
Wherein, 1, cavity plate；2nd, material-dropping hole；3rd, trapezoidal convex edge.
Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings：
Remove a specific embodiment of the mould of flash removed simultaneously referring to the utility model punching shown in Fig. 1 to Fig. 2, can
To find out, the utility model punching is gone on the mould of flash removed, including cavity plate 1 and punch-pin, the cutting edge of the material-dropping hole 2 of cavity plate 1 simultaneously
One be provided with shape and the trapezoidal convex edge 3 of material-dropping hole profile identical, the top surface of the trapezoidal convex edge 3 parallel to cutting edge top surface,
The interior facade of described trapezoidal convex edge 3 is located on the same line with the side wall of material-dropping hole 2.
Described punch-pin is shape of cross section and material-dropping hole profile identical cylinder, the highly height more than cavity plate.
Reasonable clearance (difference of the size of working portion between blanking punch and cavity plate) between described punch-pin and cavity plate 1
For the 12% of thickness of slab.
Described trapezoidal convex edge 3 is right-angled trapezium in the section of vertical direction.
The top margin length of described right-angled trapezium is 0.15mm, and base length is 1.15mm, and right angle edge lengths are 0.1mm.
Described trapezoidal convex edge 3 and cavity plate 1 are to be made into integration, and are processed using milling tool.
The utility model is punched below goes the mold use method of flash removed to be described in detail simultaneously：
In use, first cavity plate of the present utility model and punch-pin are arranged on forcing press, now locate between cavity plate and punch-pin
In released state, then by thickness for 1.5mm steel plate placing flat in molding surface, start forcing press, punch-pin is moved down, to steel plate
Apply pressure, elastic compression and bending occur for steel plate, and slightly squeeze into cavity plate material-dropping hole so that trapezoidal convex edge connects with steel plate
Tactile surface extrudes a profile and trapezoidal convex edge identical impression, and punch-pin continues to pressurize, and portion of material is squeezed into falling for cavity plate
Expect in hole, steel plate is produced plasticity detrusion, continue to be pressurized, the microcrack of punch and matrix cutting edge portion material is constantly to steel
Intralamellar part extends, and steel plate is cut off separation, because the presence of trapezoidal convex edge, the neat impulse- free robustness of fracture at random.
The utility model processes a trapezoidal convex edge on the cavity plate of mould, and this trapezoidal convex edge is first in thin sheet surface during punching
One and workpiece profile identical impression are extruded, is then separated again so that the edge after punching is neat, reduces the production of burr
It is raw；Existing mold is improved, the function of deburring is added in blanking process, when shortening the processing of workpiece entirety
Between, improve production efficiency；Trapezoidal convex edge on cavity plate is made into integration with cavity plate, makes simple, with low cost.
Exemplary description is done to the utility model above, it should explanation, do not departed from core of the present utility model
In the case of the heart, it is any it is simple deformation, modification or other skilled in the art can not spend creative work etc.
Protection domain of the present utility model is each fallen within replacing.
