Description
Technical field
The present invention relates to mold design with making, and in particular to one kind prevents jump-scrap device.
Background technology
Making mold, under certain manufacturing equipment and fabrication process condition, directly to mould parts material（It is generally golden
Belong to material）It is processed, has changed its shape, size, relative position and property, makes satisfactory part, then will
These parts through coordinate, position, connect with fixing assembling turn into mould process.
The reason for producing jump-scrap in the market mainly has 3：（1）It is true in the public generation between waste material of punching during punching press
Sky, fertilizer is taken to die face when rushing Gongshang and rising（2）Due to the effect of punching oil, waste material, which is bonded at, to be rushed male end face and takes in die face
（3）Fertilizer Yu Aomobi frictional force not enough overcomes the public influence of punching and waste material is jumped out cavity plate.
The content of the invention
Technical problem solved by the invention is exactly to be that providing one kind prevents jump-scrap device.
Technical problem solved by the invention is realized using following technical scheme：One kind prevents jump-scrap device, including：
The edge of a knife（1）, the edge of a knife（2）, connect the edge of a knife, dovetail, thimble.
The edge of a knife（1）, the edge of a knife（2）It is vertically arranged in the same direction, the edge of a knife（1）, the edge of a knife（2）It is not in contact with part；It is described to connect knife
Mouth is arranged on the edge of a knife（1）, the edge of a knife（2）Centre, connect the edge of a knife（1）, the edge of a knife（2）；The dovetail is arranged on the edge of a knife, prevents waste material
Die face is jumped to, the dovetail is detachable；The thimble is arranged on the edge of a knife, the big thick material of general processing, goes to lower dovetail, installation top
Pin.
One kind prevents jump-scrap device, enhances the frictional force of waste material and cavity plate wall, punching public affairs and fertilizer when solving punching press
Between produce vacuum the problem of, prevent waste material jump to desktop may insure production stability.Perfect operation or work standard, is applied to
Each production division's operation.
Brief description of the drawings
Fig. 1-Fig. 9 is schematic diagram of the present invention.
The edge of a knife（1）1st, the edge of a knife（2）2nd, the edge of a knife 3, dovetail 4, thimble 5 are connect.
Specific implementation method
In order that implement technical means, creation characteristic, reached purpose and effect of the present invention are easy to understand, with reference to tool
Body illustrates, and the present invention is expanded on further.
As shown in the figure：One kind prevents jump-scrap apparatus structure, including：The edge of a knife（1）1st, the edge of a knife（2）2nd, connect the edge of a knife 3, dovetail 4,
Thimble 5, the edge of a knife（1）1st, the edge of a knife（2）2 are vertically arranged in the same direction, the edge of a knife（1）1st, the edge of a knife（2）2 are not in contact with part, described to connect
The edge of a knife 3 is arranged on the edge of a knife（1）1st, the edge of a knife（2）Among 2, the edge of a knife is connected（1）1st, the edge of a knife（2）2, the dovetail 4 is arranged on the edge of a knife,
Prevent waste material from jumping to die face, the dovetail 4 is detachable, and the thimble 5 is arranged on the edge of a knife, the big thick material of general processing, goes lower swallow
Tail 4, thimble 5 is installed.
Further, the deploying of clip.
a:Punching order：When waste material has the freely space of activity in die hole, waste material is because coherence and the punching of punching public affairs
The effect waste material of force feed is easy to jump in die face:Such as the backlash edge of a knife 2 of Fig. 1 elder generations stamping knife mouth 1, small waste material is free shape in cavity plate
State, jump-scrap is easy to, therefore first stamping knife mouth 2 part of stamping knife mouth 1 again is sequentially should be in trimming；, if Fig. 2 is when connecing the edge of a knife
First punching has technical gaps part（The edge of a knife 1）, then cut another part（The edge of a knife 2）, technique oral area part is small if punching order is opposite
Waste material easily separates with big waste material, jump-scrap；
b:When the progressive die finally cuts waste material, because waste material is generally free state, thin material shell fragment can be increased such as Fig. 2 on the edge of a knife
Add dovetail, prevent it from jumping to die face to block waste material, can be directly with thimble top waste material to big thick material；
Further, the public practice is rushed.
A. plus anti-tripping waste thimble, the practice such as Fig. 6 Fig. 7；
B. the practice of anti-tripping waste thimble can not be added：
B1. circular punching is public in end face grinding angular surface or salient point, can not be drawn when designing figure, is processed according to actual conditions during die trial,
Such as Fig. 3；
B2. male end face mill R is convex, and certain plane W is stayed in R and end, and drawing need to express clearly H=T, such as schemes is rushed to the long narrow of rule
4；
B3. hole is inflated rushing Gongshang, blow waste material, such as Fig. 5 with compression sky, pore can use pore electro-discharge machining；
Further, the cavity plate practice.
A. anti-tripping waste cavity plate is used, its principle utilizes material there are two or three shallow skewed slots on cavity plate edge of a knife wall
Crimp increases the friction of material and cavity plate wall, and to prevent jump-scrap, hole shape is generally the circular square etc. of rule, palpus
Work is ordered in outsourcing（Standard is folded in reference）；
B. to sheet, jump-scrap during production, in cavity plate knife-edge part R can be fallen, R=0.02 ~ 0.05, such as Fig. 8；
C. as cavity plate can be processed into back taper by Fig. 9,（Processed with optics grinding machine）To increase the deformation of material, prevent waste material from jumping to mould
Face；
Further, other.
A. the public length for entering cavity plate of increase punching;
B. vavuum pump waste suction material is added in lower mould;
One kind prevents jump-scrap device, can be widely applied to expect the elastomeric material and aluminium flake punching and customer specific requirements of thickness,
Foreign customers are added with anti-tripping waste device (such as cool space mould) as far as possible referring in particular to Customer Standard.
The general principle and principal character of the present invention has been shown and described above.It should be understood by those skilled in the art that
The present invention is not limited to the above embodiments, merely illustrating the principles of the invention described in above-described embodiment and specification,
Without departing from the spirit and scope, various changes and modifications of the present invention are possible, and these changes and improvements all fall
Enter in scope of the claimed invention.The claimed scope of the present invention is by appended claims and its equivalent circle
It is fixed.
