Abstract
The invention discloses a flanging height precision control die which comprises an upper die portion, a lower die portion and guide support columns, wherein the guide support columns are connected with the upper die portion and the lower die portion, and the lower die portion is fixed on the ground and matched with the upper die portion. The flanging height precision control die realizes high flanging and the effect that products with heights which need to be controlled precisely can be produced on an ordinary punching machine, gets rid of the bottleneck that the productivity of a special-purpose hydraulic press is low, can increase the production efficiency of a single process by four times, can reduce the tolerance of a flanging die to a large extent, reduces secondary treatment caused by design flaws of the die, reduces investment in equipment and manpower, has high yield at low investment and can lower capacity requirements and energy consumption.
Description
Technical field
The invention belongs to punch-forming mold, be specifically related to a kind of flange height precise control mold.
Background technology
Flange is basic operation in the stamp forming technology of sheet material, is widely used.The Design and manufacture of its turnup structure mould is a critical index of Mold Making level and ability.Main flanging process has two kinds now, a kind of for before flange, a pre-punched hole is first done at the position of wanting flange, then carry out flange, this method is generally to use at present, can only be controlled in-0.2-+0.2 millimeter scope, when product was very little for the tolerance range requirement of flange height, this technique just was difficult to reach requirement.Another kind of technique is that the structure with drift changes, and pre-punched hole and flange are completed at a procedure, is prone to sawtooth but the shortcoming of doing like this is edge at flange, and flange height is uncontrollable.
Summary of the invention
In order to overcome the problems referred to above of prior art field existence, the object of the invention is to, a kind of flange height precise control mold is provided, solve existing flanging process flange precision low, the uncontrollable problem of flange height.
Flange height precise control mold provided by the invention, it comprises part of the upper die, part of the lower die, guide stanchion, and described guide stanchion is connected with part of the upper die, part of the lower die, and the part of the lower die fixes on the ground, cooperatively interacts with the part of the upper die.
Described part of the upper die comprises upper bolster, upper mold holder, flange die, punching, and described upper mold holder top is fixedly connected with upper bolster, and the bottom is fixedly connected with the flange die, is provided with punching in described flange die.
Described part of the lower die comprises flanging die, drift, keeper, lower folded block, the end of floating downward, lower bolster, die shoe, lower roof plate, described keeper is fixedly installed at the end of floating downward, flanging die is arranged at the end of floating downward, the both sides, the end of floating downward are connected with lower folded block, described drift is arranged in flanging die, coordinate with punching, the bottom of described drift, lower folded block, flanging die all is fixedly connected with lower bolster, lower bolster is fixed on die shoe, and the lower roof plate that is connected with the hydraulic press push rod coordinated with the end of floating downward.
Described guide stanchion comprises guide pillar, guide pin bushing, and described guide pillar bottom is fixedly installed on die shoe, and the guide pin bushing top is fixedly installed on upper bolster, and guide pillar coordinates with guide pin bushing.
It also comprises bottom seat pad, and described bottom seat pad is fixedly installed on below die shoe; It also comprises bottom deck, and described bottom deck is fixedly installed on the bottom of bottom seat pad and die shoe.
Flange height precise control mold provided by the invention, its beneficial effect is, this flange height precise control mold has been realized high flange and has been needed the product of essence control height to produce on common punch press, broken away from the low bottleneck of productivity ratio of special oil press, single operation is enhanced productivity 4 times, reduce significantly the tolerance of flanging die, the after-treatment that minimizing causes because of the defective on Design of Dies, the input of minimizing equipment and manpower, the high production of low input reduces production capacity demand and energy resource consumption.

The specific embodiment
With reference to the accompanying drawings, in conjunction with the embodiments, to flange height precise control mold provided by the invention, be described in detail.
Embodiment
With reference to Fig. 1-Fig. 2, the flange height precise control mold of the present embodiment, it comprises part of the upper die, part of the lower die, guide stanchion, and described guide stanchion is connected with part of the upper die, part of the lower die, and the part of the lower die fixes on the ground, cooperatively interacts with the part of the upper die.
Described part of the upper die comprises upper bolster 1, upper mold holder 2, flange die 4, punching 3, and described upper mold holder 2 tops are fixedly connected with upper bolster 1, and the bottom is fixedly connected with flange die 4, is provided with punching 3 in described flange die 4.
Described part of the lower die comprises flanging die 6, drift 16, keeper 5, lower folded block 8, the end 10 of floating downward, lower bolster 11, die shoe 12, lower roof plate 14, described keeper 5 is fixedly installed at the end 10 of floating downward, flanging die 6 is arranged at the end 10 of floating downward, the both sides, the ends 10 of floating downward are connected with lower folded block 8, described drift 16 is arranged in flanging die 6, coordinate with punching 3, the bottom of described drift 16, lower folded block 8, flanging die 6 all is fixedly connected with lower bolster 11, lower bolster 11 is fixed on die shoe 12, and the lower roof plate 14 that is connected with the hydraulic press push rod coordinated with the end 10 of floating downward.
Described guide stanchion comprises guide pillar 9, guide pin bushing 7, and described guide pillar 9 bottoms are fixedly installed on die shoe 12, and guide pin bushing 7 tops are fixedly installed on upper bolster 1, and guide pillar 9 coordinates with guide pin bushing 7.
