Abstract
The utility model relates to an mouth mould that expands for X-shaped metal parts shaping for material consumption is big when solving X-shaped metal parts shaping and the problem of conventional mould shaping back part drawing of patterns difficulty, including last mould and lower mould, last mould outside both sides be the mouth working face that expands on upper portion, the mouth working face that expands on upper portion adopt the inclined plane structure, the angle of inclined plane structure is greater than the angle that X-shaped metal parts upper portion erects the limit fillet, last mould and the inside corresponding die cavity that forms of lower mould unanimous with X-shaped metal parts's central shape, as X-shaped metal parts's location. The die is simple in structure and convenient to operate, and the expansion forming of the two sides of the X-shaped metal part is realized.
Description
Technical Field
The utility model relates to a metal forming die field, concretely relates to mouth mould that expands for X shape metal part shaping.
Background
At present, an existing X-shaped metal part is used for forming parts of metal belt pulleys and wheels, as shown in figures 1-2, concave angles are formed on two sides during production of the X-shaped metal part, the X-shaped metal part is generally processed in a shape containing mode, metal is filled in the concave inner side of the vertical edge on the upper portion of the X-shaped metal part, therefore, the processing allowance of the concave portion of the vertical edge on the upper portion of the X-shaped metal part needs to be increased, a large amount of material waste is caused, and the parts are difficult to demould after being formed by a conventional die.
Disclosure of Invention
Based on above weak point, the utility model provides an expanding die for X shape metal parts shaping for material consumption is big when solving X shape metal parts shaping and the problem of part drawing of patterns difficulty behind the conventional mould shaping.
The technical proposal adopted by the utility model is that: the utility model provides an expand mouthful mould for X shape metal part takes shape, includes mould and lower mould, the outside both sides of last mould be upper portion mouth working face that expands, upper portion mouth working face that expands adopt inclined plane rounding off structure, the angle of inclined plane rounding off structure is greater than the angle of X shape metal part upper portion vertical edge fillet, the mould and the inside corresponding die cavity that forms of lower mould unanimous with the central shape of X shape metal part, as the location of X shape metal part.
The utility model discloses still have following technical characteristic:
1. the shapes of the two sides of the outer part of the lower die correspond to the shapes of the two sides of the lower part of the X-shaped metal part, and the lower die does not participate in the expansion forming.
2. The angle of the bevel smooth transition structure is 32 degrees.
The utility model has the advantages that: the utility model discloses mould simple structure, convenient operation has realized the mouth that expands of X shape metal part both sides and has taken shape, has solved the problem of X shape metal part forming process auxiliary angle drawing of patterns difficulty.
Drawings
FIG. 1 is a pre-form view of an X-shaped metal part;
FIG. 2 is a view of an X-shaped metal part;
FIG. 3 is a sectional view of the mold assembly of example 1;
fig. 4 is a cross-sectional view of the upper mold of example 1.
Detailed Description
The invention is further described with reference to the accompanying drawings and the detailed description:
example 1
As shown in fig. 3-4, an opening expanding die for forming an X-shaped metal part is used for expanding an upper vertical edge of the X-shaped metal part and comprises an upper die 1 and a lower die 2, wherein two sides of the outer part of the upper die 1 are upper opening expanding working faces used for expanding an upper vertical edge of the X-shaped metal part, the upper opening expanding working faces adopt an inclined smooth transition structure, an angle R20 of the inclined smooth transition structure is 32 degrees, the angle is a final forming angle of an upper vertical edge inner cavity of the X-shaped metal part and is larger than an angle of an upper vertical edge fillet R10 of the X-shaped metal part, so that the part is guided to be formed, and a cavity correspondingly formed in the inner parts of the upper die 1 and the lower die 2 is consistent with the central shape of the X-shaped metal part and is used for positioning the X-shaped metal part. The shapes of the two sides of the outer part of the lower die 2 correspond to the shapes of the two sides of the lower part of the X-shaped metal part, and the lower die does not participate in the expansion forming. In the forming process, the preformed part is placed into the lower die 2 for positioning after being preformed, the upper die 1 is driven to descend along with the descending of a workbench on a press, the working part of the upper die 1 extends into the inner wall of the vertical edge at the upper part of the part, the vertical edge at the upper part of the part expands outwards along the inclined plane of the outer wall of the upper die 1 to deform, and finally the required shape is achieved.
Example 2
Procedure for use of the mold of example 1:
the first step is as follows: an upper die 1 and a lower die 2 of an expansion die for forming an X-shaped part are respectively arranged on an upper working platform and a lower working platform of a forming press.
The second step is that: and starting the forming machine to open the upper die and the lower die, sleeving the preformed X-shaped metal part on the surface of the lower die cavity, and positioning the part by using the cavity of the lower die.
The third step: the upper die moves downwards, the inclined planes of the working expansion openings on the two sides of the upper die contact the upper vertical edge of the X-shaped metal part firstly, the angle of the inclined plane of the upper die is larger than the angle of the fillet of the upper vertical edge of the X-shaped metal part, a guiding effect is achieved, along with the descending of the upper die, the inner wall of the upper vertical edge of the X-shaped metal part deforms along the appearance of the working face of the expansion opening of the upper die until the pressing of the upper die and the lower die, and the part is finally formed.
The fourth step: and lifting the upper workbench of the forming press to open the upper die and the lower die and taking out the formed parts.
