Abstract
The utility model provides a flanging once-molding mould which is simple in structure and ensures processing precision of products. The flanging once-molding mould comprises an upper mould and a lower mould provided with a concave mould hole, the concave mould hole comprises a flanging hole and a blanking hole, the flanging hole is formed in the top face of the lower mould, the flanging hole and the blanking hole are uniform in shape, and the size of the flanging hole is larger than the size of the blanking hole. According to the flanging once-molding mould, the concave mould hole is divided into the flanging hole and the blanking hole, panels deform gradually when the upper mould punches downward, the panels finish deformation, a flanging height is formed when the cutting edge of the upper mould and the cutting edge of the lower mould contact, the upper mould continues to punch downward, and a punching hole is formed. The flanging once-molding mould is formed downward, is different from the fact that a mould in the prior art is formed upward and the mould punches a hole first and then flanges, and is mainly applied to a water tank radiator or a cooler main board.
Description
Technical field
The utility model relates to mould, relates in particular to the improvement to the piercing and flanging mould.
Background technology
In existing diel, the flange of product sheet material has two kinds of production methods, a kind of is the drift that is varied in size by two top end diameter, subpunch pre-punched hole, back flange two procedures are come moulding, i.e. first little drift punching and blanking, the big drift flange in back is finished by two procedures, production efficiency is low, the cost height.Another kind is a flange moulding, its use state is that the big or small drift in last a kind of method is united two into one, punching section (little drift) is positioned at front end, flange section (big drift) is positioned at the back of punching section, drift processes at one time punching, flange two procedures, has improved production efficiency, yet when drift is processed, drift need be processed into big or small drift, processing request is higher.
The utility model content
The utility model provides a kind of simple in structure at above problem, guarantees the flange one-time-shaped mould of processing precision of products.
The technical solution of the utility model is: comprise patrix and the counterdie with die hole; Described die hole comprises flange hole and material-dropping hole, and described flange hole is located at the end face of described counterdie, and the shape of described flange hole and material-dropping hole is consistent, and the size in described flange hole is greater than the size of described material-dropping hole.
Described counterdie is provided with the counterdie unloading mechanism, and both sides and front end in described counterdie die hole are provided with up-small and down-big shoulder hole, and described counterdie unloading mechanism is located in the described shoulder hole;
Described counterdie unloading mechanism comprises counterdie material returned nail, spring and tightening plug screw, described counterdie material returned nail has nail body and ailhead, the small stair hole of described nail body and described shoulder hole is adaptive and place described small stair hole, described ailhead to be located in the big stepped hole of described shoulder hole; Described spring is located between described counterdie material returned nail and the tightening plug screw.
Described flange hole is long lumbar hole.
Flange one-time-shaped mould in the utility model is divided into flange hole and material-dropping hole two parts with the die hole, under patrix towards the time, sheet material is distortion gradually earlier, when the patrix cutting edge contacts with the counterdie cutting edge, sheet deformation finishes, and forms the flange height, and patrix continues to dash down to form punching.One-time-shaped mould in the utility model is to compacted under, is different from the upwards moulding of flange after the first punching of the prior art, is mainly used on radiator of water tank or the cooler mainboard.

The specific embodiment
The utility model comprises patrix 3 and the counterdie 6 with die hole shown in Fig. 1-6; Described die hole comprises flange hole 61 and material-dropping hole 62, described flange hole 61 is located at the end face (namely towards described patrix 3) of described counterdie 6, described flange hole 61 is consistent with the shape of material-dropping hole 62, and the size in described flange hole 61 is greater than the size of described material-dropping hole 62.
At work, a whole set of mould also comprises top board 1, spring base 2, dish spring 8, pusher cover 4 and pusher cover cover plate 5, and spring base 2 and pusher cover 4 are realized the location by alignment pin 7.
Described counterdie 6 is provided with the counterdie unloading mechanism, and both sides and front end in described counterdie die hole are provided with up-small and down-big shoulder hole 13, and described counterdie unloading mechanism is located in the described shoulder hole 13;
Described counterdie unloading mechanism comprises counterdie material returned nail 9, spring 10 and tightening plug screw 11, described counterdie material returned nail 9 has nail body and ailhead, the small stair hole of described nail body and described shoulder hole 13 is adaptive and place described small stair hole, described ailhead to be located in the big stepped hole of described shoulder hole 13; Described spring 10 is located between described counterdie material returned nail 9 and the tightening plug screw 11.
Shown in Fig. 5-6, described flange hole 61 is long lumbar hole, and sheet material 12 processes the structure in flange hole.
