Description

Corner bending and blanking die machining structure

Technical Field

The utility model belongs to the technical field of backplate mould processing technology and specifically relates to a corner blank mould processing structure of bending.

Background

The existing back plate often has a dead edge of part processing in the actual processing process, mainly because of the relation of assembling a rubber frame, the edge needs to be straight after the back plate is formed. If the edge is designed according to a conventional die, the edge line needs to be trimmed in the next procedure after the edge is bent for the first time, but the edge can only be laterally cut under the technical scheme of the conventional die, so that the bent edge is not straight after the corner is bent. The corner is bent or the edge lines of the corner flanging are not parallel and level, and the influence on the appearance of the product or the influence brought by the product in the follow-up production process can be avoided. Meanwhile, some products are required to be parallel and level at the corner bending back side line, the cost factor of the die is considered, and the subsequent work cannot be carried out on the side again, so that the existing processing mode cannot meet the actual processing requirement easily.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a bending forming back at the corner is provided, blank processing is carried out to the turn-ups on dead limit to guarantee the straight corner of turn-ups blank mould processing structure of bending.

The utility model provides a technical scheme that its technical problem adopted is: the corner bending and blanking die machining structure comprises a material pressing plate and a lower die forming insert arranged below the material pressing plate, wherein punches are arranged on the side edges of the material pressing plate and the lower die forming insert; the punching die comprises a part to be machined, wherein one end of the part to be machined is arranged between a pressure plate and a lower die forming insert, the other end of the part to be machined is arranged between the lower die forming insert and a punch, when the punch moves downwards, a guide angle end of the punch firstly conducts guide angle machining on the middle section of the part to be machined, and then the material cutting end of the punch realizes material cutting on the dead edge of the part to be machined.

Further, a lower die extruding and cutting edge insert is arranged at the bottom of the lower die forming insert, and the material cutting end and the lower die extruding and cutting edge insert are matched with each other to realize material cutting.

Furthermore, the material cutting end is matched with a lower die trimming edge arranged on the side edge of the lower die extrusion trimming insert to realize material cutting.

Further, the lead angle end is a round angle.

The utility model has the advantages that: during actual processing, one end of a part to be processed is arranged between the pressure plate and the lower die forming insert and is pressed tightly through the pressure plate. And then, the punch is driven to move downwards, the guide angle end of the punch firstly performs stamping material pressing processing on the middle section of the processed part so as to realize a corresponding processing effect, and the material cutting end of the punch realizes material cutting on the dead edge of the part to be processed along with the continuous downward movement of the punch, so that the material pressing and edge cutting effects are completed by one stamping action, and the processing efficiency is greatly improved. The utility model discloses be particularly useful for among the processing of corner bending blank.

Drawings

Fig. 1 is a schematic diagram of the present invention.

Labeled as: the stamping die comprises a punch 1, a guide angle end 11, a blanking end 12, a pressure plate 2, a part to be processed 3, a dead edge 31, a lower die forming insert 4, a lower die extrusion trimming insert 5 and a lower die trimming 51.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

The corner bending and blanking die processing structure shown in fig. 1 comprises a pressure plate 2 and a lower die forming insert 4 arranged below the pressure plate 2, wherein punches 1 are arranged on the side edges of the pressure plate 2 and the lower die forming insert 4; the processing method comprises a part 3 to be processed, wherein one end of the part 3 to be processed is arranged between a pressure plate 2 and a lower die forming insert 4, the other end of the part 3 to be processed is arranged between the lower die forming insert 4 and a punch 1, when the punch 1 moves downwards, a guide angle end 11 of the punch 1 firstly conducts guide angle processing on the middle section of the part 3 to be processed, and then a material cutting end 12 of the punch 1 cuts a dead edge 31 of the part 3 to be processed.

When the punch 1 is driven to move downwards, the lead angle end 11 of the punch 1 firstly performs stamping and material pressing processing on the middle section of the part 3 to be processed so as to achieve a corresponding processing effect, and the material cutting end 12 of the punch 1 performs material cutting on the dead edge 31 of the part to be processed along with the continuous downward movement of the punch 1, so that the material pressing and edge cutting effects are completed through one stamping action, and the processing efficiency is greatly improved. The utility model discloses be particularly useful for among the processing of corner bending blank. Wherein the leveling effect is achieved after the dead edge 31 is cut. In practical design, the fillet end 11 is preferably a round angle.

In general, in order to ensure that the blanking end 12 can accurately and reliably perform blanking on the dead edge 31 when moving downwards along with the punch 1, the following scheme is preferred: the bottom of the lower die forming insert 4 is provided with a lower die extruding and cutting insert 5, and the material cutting end 12 and the lower die extruding and cutting insert 5 are matched with each other to realize material cutting. As shown in fig. 1, the pair of dead edges 31 is cut by the cooperation of the cutting end 12 and the lower die pinch-off trim insert 5. Further, the material cutting end 12 is preferably matched with a lower die trim 51 provided at the side of the lower die press-cutting trim insert 5 to perform material cutting.
