Description
Technical Field
The utility model belongs to the technical field of the stamping die technique and specifically relates to a die-cut mould of semi-circular cross-section of half shell admits air.
Background
The conventional side-cutting process requires two steps: the two sides are cut at the side, and then the middle is cut off. The side cutting needs the tapered wedge, the manufacturing cost is high, the requirement on the machining precision is high, and the die repairing difficulty is high.
Therefore, the semi-circular section punching die for the air inlet half shell needs to be designed, and side cutting can be completed without a wedge, so that the production cost is reduced, and the die repairing difficulty is reduced.
Disclosure of Invention
The utility model aims at overcoming the not enough of prior art, providing a die-cut mould of semi-circular cross-section of half shell admits air, do not need the slide wedge can accomplish the side and cut to reduction in production cost and the mould degree of difficulty of repairing.
In order to achieve the aim, the utility model relates to a die-cut mould of semi-circular cross section of half shell admits air, include upper die base, punch holder, deburring drift, lean on sword, die holder, take off flitch, lower bolster, its characterized in that: an upper clamping plate and a stripper plate are fixed at the bottom of an upper die base, two trimming punches are mounted on the upper clamping plate through rotating shafts and are arranged on the upper clamping plate, a spring is arranged between the two trimming punches, two rest knives and a lower backing plate are fixed at the top of a lower die base, the two rest knives are respectively positioned on the front side and the rear side of the trimming punches, an inclined plane structure is arranged on one side, close to the trimming punches, of the rest knives, and the outer sides of the trimming punches are in contact with or separated from the inclined plane structure of the rest knives.
The left side of the top of the lower base plate is provided with a lower die knife edge.
Compared with the prior art, the utility model, designed the die-cut mould of semi-circular cross section of half shell admits air, can realize the side cut of product through the deburring drift, and do not need extra slide wedge, reduced manufacturing cost, also reduced the degree of difficulty of repairing the mould.

Detailed Description
The invention will now be further described with reference to the accompanying drawings.
Referring to fig. 1, the utility model relates to a die-cut mould of semi-circular cross section of half shell admits air, including the upper die base, the punch holder, the deburring drift, lean on the sword, the die holder, take off the flitch, lower bolster, the bottom of upper die base 1 is fixed with punch holder 2 and takes off flitch 6, install two deburring drifts 3 on the punch holder 2, deburring drift 3 adopts pivot 9 to install on punch holder 2, be equipped with spring 8 between two deburring drifts 3, the top of die holder 5 is fixed with two and leans on sword 4 and lower bolster 7, two lean on sword 4 to be located the front side and the rear side of deburring drift 3 respectively, one side of leaning on sword 4 to be close to deburring drift 3 is equipped with the inclined plane structure, the outside of deburring drift 3 with the inclined plane structure contact or the separation of leaning on sword.
The utility model discloses in, the top left side of lower bolster 7 is equipped with lower mould edge of a knife 11, and lower mould edge of a knife 11 cuts off the waste material under the effect of drift.
Referring to fig. 2, when the punching machine of the present invention is in the mold opening state, the trimming punch 3 is in the expanded state under the action of the spring 8.
Referring to fig. 3, when the die works, the upper platform of the punch moves downward, the stripper plate 6 presses the product 10 first, and the trimming punch 3 moves downward along with the upper platform of the punch and contacts the inclined plane structure of the cutter 4.
Referring to fig. 4, the slotting tool is inserted into the cutter 4, and the trimming punch 3 is rotated about the rotary shaft 9 by the cutter 4. After the trimming punch 3 rotates to a certain angle, the trimming punch 3 starts to cut edges.
Referring to fig. 5, after the side cutting is completed, the table of the press moves upward. The trimming punch 3 is withdrawn from the rest knife 4 and is reset under the action of the spring 8. The product 10 floats up and advances one step and starts the next process.
The utility model discloses a die-cut mould of semi-circular cross-section of half shell admits air can realize the side cut of product through the deburring drift, and does not need extra slide wedge, has reduced manufacturing cost, has also reduced the degree of difficulty of repairing the mould.
