Abstract

A kind of body of a motor car cold punching die carrying out die face process, belong to the technical field of automobile body part cold punching die, in order to solve because plate vibration makes the sheet material on mould have the problem of cut, technical essential is: blank holder is placed in the below of die and is socketed in the periphery of punch, described die has die die face, die die face is the die face with an angle, an angle in described die die face is that die die face suppresses district, described punch has punch die face, and described punch die face is placed in the below of die die face and parallels with die die face.Punch die face is placed in the below of die die face and parallels with die die face by the utility model, makes its plate in the process of mould, there will not be play phenomenon, thus the smooth no marking of processed plate surface.

Description

The body of a motor car cold punching die of die face process can be carried out
Technical field
The utility model belongs to the technical field of automobile body part cold punching die, relates to the cold punching die in this field, and more particularly, the utility model relates to a kind of body of a motor car cold punching die carrying out die face process.
Background technology
Body of a motor car cold punching die requires the highest, processing, assembling, the maximum mould of debugging difficulty in body of a motor car manufacture, and the cold punching technology developed rapidly in the electronic product manufacture of Ye Shi China is equipped.Tool and Die Technology, to promoting that the development of national economy has the meaning of particular importance, day by day plays significant role in the large-scale production of modern industry.Wherein surface quality of workpieces is the key component of body of a motor car.Therefore, body of a motor car punching press parts produce the quality of product surface quality, directly affect assembling and the sales volume of automobile.
Utility model content
The utility model provides a kind of body of a motor car cold punching die carrying out die face process, in order to solve in drawing operation, because plate vibration makes the sheet material on mould have the problem of the problem of cut and the bodywork parts surface relief injustice of machine-shaping.
For achieving the above object, the technical solution adopted in the utility model is: a kind of body of a motor car cold punching die carrying out die face process, comprise die, punch, blank holder, die shoe and lathe push rod, described punch is supported by die shoe, described blank holder is supported by lathe push rod, and blank holder is placed in the below of die and is socketed in the periphery of punch, described die has die die face, die die face is the die face with an angle, an angle in described die die face is that die die face suppresses district, described punch has punch die face, described punch die face is placed in the below of die die face and parallels with die die face.
Beneficial effect: die die face of the present utility model has a die die face and suppresses district, punch die face be placed in the below of die die face and parallel with die die face, make its plate in the process of mould, there will not be play phenomenon, thus the smooth no marking of processed plate surface, also make the bodywork parts surface of machine-shaping same level and smooth, no concave-convex phenomenon simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1. die, 2. punch, 3. blank holder, 4. die shoe, 5. lathe push rod, 6. die die face, 7. die die face suppresses district, 8. punch die face.
Detailed description of the invention
In order to set forth the invention further, below in conjunction with drawings and the specific embodiments, the utility model is described.
Embodiment:
The present embodiment relates to a kind of body of a motor car cold punching die carrying out die face process, comprise die 1, punch 2, blank holder 3, die shoe 4 and lathe push rod 5, described punch 2 is supported by die shoe 4, described blank holder 3 is supported by lathe push rod 5, and blank holder 3 is placed in the below of die 1 and is socketed in the periphery of punch 2, described die 1 has die die face 6, die die face 6 is the die face with an angle, an angle in described die die face 6 is that die die face suppresses district 7, described punch 2 has punch die face 8, described punch die face 8 is placed in the below of die die face 6 and parallels with die die face 6.
The body of a motor car cold punching die of the carried out die face process in the present embodiment carries out die face processing procedure and is:
Die face process is carried out in the die 1 of drawing operation, select to carry out die face process in the position of product crest line and periphery, the length with the 30mm at an angle in die die face 6 is suppressed 7 pairs, district product profile as die die face and carries out excess processes, the attached type of profile in the middle of product.Wherein, swirling flows is done in crest line and the periphery of product, and 0.1mm suppressed by die, when the body of a motor car cold punching die work can carrying out die face process, first contacted with blank holder 3 by die 1, descending together, during 0.1mm before on earth, the crest line of product and periphery are done the position of suppressing and are first contacted with punch 2, plate is compressed, prevent plate to be stretched, utilize this process to ensure the plate not vibration at crest line and surrounding place, avoid plate surface occur cut and pull.
By using the body of a motor car cold punching die that can carry out die face process, make its plate in the process of mould, there will not be play phenomenon, thus the smooth no marking of processed plate surface, also make the bodywork parts surface of machine-shaping same level and smooth simultaneously, no concave-convex phenomenon, improves the quality of product.
The above; be only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and utility model design thereof and replace or change, all should be encompassed within protection domain of the present utility model.
