Abstract
The utility model relates to a metal punching mold, and particularly to a metal flange height precise control mold. The flange height precise control mold comprises a base (3), wherein the base (3) is provided with a concave hole (5), wherein the bottom part of the concave hole (5) is embedded into a stripping insert (4), the length of the stripping insert (4) is smaller than the depth of the concave hole (5), and a former punch (1) is arranged right above the concave hole (5).Due to the adoption of the flange height precise control mold, the problem that the flange height cannot reach the size requirement of the product can be solved, and the flange height tolerance of the product is controlled within the range of minus 0.05mm to plus 0.05mm by optimizing the entire structure of the flange mold.
Description
Technical field
The utility model relates to a kind of metal stamping mould, relates in particular to the accurately mould of control of a kind of metal flange height.
Background technology
Flange is a kind of basic working procedure of drawing, obtained using widely, main flanging process has two kinds now, a kind of for before flange, a pre-punched hole is done at the position of wanting flange earlier, carry out flange then, this also is the method for generally using at present, can only be controlled at-0.2-+0.2 millimeter scope in, when product was very little for the tolerance range requirement of flange height, this technology just was difficult to reach requirement.Another kind of technology is that the structure with drift changes, and pre-punched hole and flange are finished at a procedure, is prone to sawtooth but the shortcoming of doing like this is a edge at flange, and the flange height can't management and control.
The utility model content
Technique effect of the present utility model can overcome above-mentioned defective, and the smart control of a kind of flange height mould is provided, and it has improved flange quality and precision.
For achieving the above object, the utility model adopts following technical scheme: it comprises base, and base is provided with shrinkage pool, and the shrinkage pool bottom embeds takes off the material mold insert, takes off the degree of depth of the length of material mold insert less than shrinkage pool, is provided with drift directly over the shrinkage pool.
The utility model carries out workpiece earlier then boss to be carried out the part punching towards the boss operation, i.e. the both sides of a boss reservation part is not carried out punching.Again remaining on-perforated boss is carried out flange, the height of flange is that the height of boss both sides adds the length that on-perforated boss both sides keep like this.Can accurately control the height of flange by accurately controlling towards the height of boss and the size of punching.
The length of taking off the material mold insert is 1-5CM less than the degree of depth of shrinkage pool, and towards the difference in height decision by both of the height of boss, difference in height can be by taking off the length adjustment of material mold insert.
The utility model has solved the problem that the flange height can't reach the size of product requirement, by optimization, the flange height tolerance of product is controlled to whole flanging die structure-the 0.05-+0.05 millimeter in.
Description of drawings
Fig. 1 is that the utility model is towards boss operation structural representation;
Fig. 2 is the utility model pre-punched hole operation structural representation;
Fig. 3 is the utility model overturning process structural representation.
Among the figure: 1. drift; 2. workpiece; 3. base; 4. take off the material mold insert; 5. shrinkage pool.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in detail:
Mould of the present utility model comprises base 3, and base 3 is provided with shrinkage pool 5, and shrinkage pool 5 bottoms embed takes off material mold insert 4, takes off the degree of depth of the length of material mold insert 4 less than shrinkage pool 5, is provided with drift 1 directly over the shrinkage pool 5.
The length of taking off material mold insert 4 is 1-5CM less than the degree of depth of shrinkage pool 5.
In order to guarantee the margin of tolerance of product flange height, need carry out flange to product through three operations: (1) at first needs workpiece 2 is gone out a boss, the appearance and size of workpiece 2 is by the size decision of shrinkage pool 5 in this process, and the height of boss is guaranteed with the difference of taking off material mold insert 4 height by the degree of depth of shrinkage pool 5.(2) then workpiece 2 is carried out pre-punched hole before the flange, the size in its hole is that the diameter in hole is less than the width of boss by the size decision of drift 1.(3) carry out overturning process at last, the height of flange is highly determined by the degree of depth and the demoulding mold insert 4 of shrinkage pool 5.
Claims (2)
1. a flange height essence is controlled mould, it is characterized in that, comprise base (3), base (3) is provided with the embedding of shrinkage pool (5) shrinkage pool (5) bottom and takes off material mold insert (4), take off the degree of depth of the length of material mold insert (4), be provided with drift (1) directly over the shrinkage pool (5) less than shrinkage pool (5).
2. the smart control of flange height according to claim 1 mould is characterized in that, the length of taking off material mold insert (4) is 1-5CM less than the degree of depth of shrinkage pool (5).
