Description
Technical field
The utility model belongs to the parts of cold stamping punching turned welt mould, the especially die of piercing and flanging mould.
Background technology
Along with the raising of cold punching die technology, it requires mould to complete as much as possible more content in a procedure, adopts at present disposable pre-punched hole and two the technique contents of turned welt of completing of piercing and flanging, has the difficult shortcoming of separating of waste material after the punching turned welt.
Summary of the invention
For waste material after making the punching turned welt separates fully, the utility model proposes the die of piercing and flanging mould.
The technical solution of the utility model is: the die of piercing and flanging mould, comprise the die body, the upper surface of die body is the workpiece support face, it is characterized in that: the die body is provided with the guiding stepped hole, be provided with movable matrix in the guiding stepped hole, movable matrix passes through spring supporting.
Beneficial effect: the utility model is improved on the basis of die traditional structure, adds a movable matrix in the die body, and waste material is separated fully; The utlity model has simple in structure, cost is low, the characteristics of highly versatile.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The die of punching turned welt mould as shown in Figure 1, the upper surface of die body 1 is the workpiece support face, and die body 1 is provided with the guiding stepped hole, in the guiding stepped hole, is provided with movable matrix 2, and movable matrix 2 supports by spring 3.During use, the die body is fixed on (punching turned welt mould) fixed head 4.
Operation principle: during use, the flange piercing punch moves down, first punching; The flange piercing punch continues to move down, and then movable matrix moves down, and completes the flange in hole simultaneously.The utility model adds a movable matrix structure on the die body, just can wash out waste material fully and not affect flanging forming.
