Abstract
The utility model discloses a die capable of solving the cracking problem of floor parts during the draw forming process, and is characterized in that a drawing rib for absorbing excess materials is arranged on the materials pressing surface of die with excessive materials flow rate, and the trend of the drawing rid is parallel to a feeding direction. The drawing rib can absorb excess materials during the draw processing process, so that materials can flow smoothly. The utility model solves the cracking problem during the middle part forming process.
Description
Technical field
The utility model relates to a kind of mould of automobile internal covering part draw forming.
Background technology
The ground plate parts belongs to C class part in the automobile panel, has complex-shapedly, and the hole is many, and drawing depth is big, not the characteristics of easy-formation.At present the Sheet Metal Forming Technology scheme of industry general implementation is: during drawing modeling in order to be lowered into the moldeed depth degree, with the product flange face directly as binder surface.The benefit of this scheme be the designer when the Sheet Metal Forming Technology shape-designing, fairly simple, the efficient height, its maximum drawback is exactly the quality control of having ignored the product forming process.Determined by the design feature of product own, this product part has indent, zone that change of shape is violent, material flows to this zone in a large number in the forming process, causes local many material wrinkling and stoped the smooth and easy of material to flow, and causes the middle part can't replenish material and tears.Therefore, the design of the Sheet Metal Forming Technology scheme of science and moulding is extremely important for mould development success or not, cost height, quality quality.
The utility model content
Technical problem to be solved in the utility model provides a kind of mould that ftractures when rationally, effectively solving floor class part drawing and moulding.
For solving the problems of the technologies described above, the technical solution of the utility model is: the mould that ftractures when solving floor class part drawing and moulding, be provided with the bead that is used to absorb excess stock on the excessive binder surface of flow of material on the described mould, the trend of described bead is parallel with feedstock direction.
As optimized technical scheme, described bead is for drawing concave bar.
As another kind of optimal technical scheme, described bead is for drawing convex tendon.
Owing to adopted technique scheme, solve the problem that ftractures when floor class part drawing is shaped, on the excessive binder surface of flow of material on the described mould, be provided with the bead that is used to absorb excess stock, the trend of described bead is parallel with feedstock direction.Draw and add man-hour, bead can sponge unnecessary material, and it is smooth and easy to guarantee that material flows into, and the utility model has solved the cracking problem the when middle part is shaped effectively.
Description of drawings
Fig. 1 is the structural representation after workpiece process the utility model embodiment draws processing;
Fig. 2 is the cutaway view of A-A face among Fig. 1;
Fig. 3 is the enlarged drawing at I place among Fig. 2.
Among the figure: the 1-workpiece; 2-draws concave bar.
The specific embodiment
Solve the mould that ftractures when floor class part drawing is shaped, be provided with the bead that is used to absorb excess stock on the excessive binder surface of flow of material on the described mould, the trend of described bead is parallel with feedstock direction.Fig. 1, Fig. 2 and Fig. 3 show through described mould and draw the structural representation of processed workpiece 1, and in the present embodiment, described bead adopts and draws concave bar 2.Described bead also can adopt and draw convex tendon.
These beads have effectively solved the ground plate parts and have added man-hour drawing, because local wrinkling to cause material to flow not smooth, cause the middle part material to be difficult to replenish and produce the phenomenon of cracking.
More than be the application's a specific embodiment, should be understood that these embodiment only be used to the invention is described and be not used in the restriction the invention scope.Should be understood that in addition those skilled in the art can make various changes or modifications the invention after the content of having read the invention instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Claims (3)
1. solve the mould that ftractures when floor class part drawing is shaped, it is characterized in that: be provided with the bead that is used to absorb excess stock on the excessive binder surface of flow of material on the described mould, the trend of described bead is parallel with feedstock direction.
2. the mould of cracking when solution as claimed in claim 1 floor class part drawing is shaped, it is characterized in that: described bead is for drawing concave bar.
3. the mould of cracking when solution as claimed in claim 1 floor class part drawing is shaped, it is characterized in that: described bead is for drawing convex tendon.
