The utility model has the advantages that: the burden of mould debugging personnel is greatly reduced, the production efficiency of the mould can be improved, and the product percent of pass is improved; the replacement is convenient, and the debugging cost and the die material cost are reduced.
Description
Technical Field
The utility model relates to a stamping forming's field, concretely relates to punching press boss forming die structure with adjustable.
Background
The boss is a convex hull structure protruding out of the plane of the part in the stamping part, the convex hull structure is different from a common convex hull, the top of the convex hull structure is a small plane, and the convex hull structure is sometimes used as a reference plane and sometimes used as a bolt fixing plane.
As shown in fig. 2, which is a schematic view of the processing of a material sheet (1), the prior art uses a mode of closing an upper die and a lower die by punching down to punch the material sheet into a boss shape. According to the size requirement of the boss part on the material sheet to be processed, the small plane (2) on the boss is one of the reference planes, and the hole on the small plane is a positioning hole. For such a plane with special function, the requirement for flatness is particularly high and a corresponding area size is to be achieved, otherwise the positioning of other positions is affected as a reference plane during welding.
The prior art is adopted for stamping, and the following defects exist:
1. the prior art can only meet the boss without special requirements, and for the boss with special requirements, the plane of the boss is often arc-shaped after the punching is finished because the plane of the boss is smaller;
2. the prior art scheme has poor adjustability, and if the molded surface can not meet the requirements, the die can not be independently repaired, the whole die needs to be replaced, the cost is high, and the operation difficulty is high.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art and provide an adjustable stamping boss forming die structure, which enables the boss plane with special requirements on a stamping part (sheet) to be formed in place, and is convenient for ensuring that the size requirement of an assembly is met in the subsequent welding process and the assembly process; meanwhile, the damage and waste of die materials in the die debugging and maintaining processes are reduced, the structure is more beneficial to replacement, and the cost is lower.
The purpose of the utility model is accomplished through following technical scheme: the adjustable stamping boss forming die structure comprises an upper die and a lower die, a material sheet to be processed is placed between the upper die and the lower die, and an arc-shaped groove is formed in the middle of the upper die and used for containing a small plane formed after the material sheet is stamped; a groove is formed in the lower die corresponding to the arc-shaped groove and used for placing a movable insert, so that the movable insert is positioned below the arc-shaped groove; a certain gap is arranged between the movable insert and the lower die and used for placing an adjusting gasket; the material sheet is punched by an upper die and a lower die to form a small plane.
As a further technical scheme, the thickness of the adjusting shim is adjusted according to the material sheet, so that the top height of the movable insert is adjusted, and the gap between the movable insert and the upper die is smaller than the thickness of the material sheet.
The utility model has the advantages that:
1. the burden of mould debugging personnel is greatly reduced, the production efficiency of the mould can be improved, and the product percent of pass is improved;
2. the replacement is convenient, and the debugging cost and the die material cost are reduced.

Description of reference numerals: the die comprises a material sheet 1, a small plane 2, an upper die 3, an arc-shaped groove 3-1, a lower die 4, a movable insert 5 and an adjusting gasket 6.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings:
example (b): as shown in fig. 3, the adjustable stamping boss forming die structure comprises an upper die 3 and a lower die 4, a material sheet 1 to be processed is placed between the upper die 3 and the lower die 4, and a small plane 2 is formed at the central position of the material sheet 1 after the material sheet is stamped by the upper die 3 and the lower die 4; an arc-shaped groove 3-1 is formed in the middle of the upper die 3 and used for containing a small plane 2 formed after the material sheet 1 is stamped; a groove is formed in the lower die 4 corresponding to the arc-shaped groove 3-1 and used for placing the movable insert 5, so that the movable insert 5 is positioned right below the arc-shaped groove 3-1 and the small plane 2 to be processed; a certain gap is formed between the movable insert 5 and the lower die 4 and used for placing an adjusting gasket 6, and the thickness of the adjusting gasket 6 is adjusted according to the material sheet 1, so that the top height of the movable insert 5 is adjusted, and the gap between the movable insert 5 and the upper die 4 is smaller than the thickness of the material sheet 1.
The utility model discloses a working process: a certain gap is arranged between the movable insert 5 and the lower die 4, and the upper and lower positions of the movable insert 5 are adjusted by using adjusting gaskets 6 with different thicknesses. The gap between the movable insert 5 and the upper die 4 is smaller than the thickness of the material sheet 1, so that acting force larger than other parts is generated on the small plane 2 in the stamping forming process, and the small plane 2 on the boss of the material sheet 1 is ensured to be formed in place and simultaneously meet the flatness requirement.
It should be understood that equivalent substitutions or changes to the technical solution and the inventive concept of the present invention should be considered to fall within the scope of the appended claims for the skilled person.
