Abstract
The utility model discloses a trimming die which comprises a lower die base, a trimming male die and a trimming female die, wherein the trimming male die is fixed on the lower die base, and the trimming female die is fixed on an upper die base and matched with the trimming male die. The trimming further comprises circular waste cutters which are arranged on two sides of the trimming male die and fixedly connected with the lower die base, the circular waste cutters comprise cylindrical cutter blocks, cutter blades are arranged at top ends of the cutter blocks, and lower ends of the cutter blocks are fixedly connected with the lower die base. The trimming die has the advantages that the waste cutters do not easily interfere with borders of manufacture pieces, and scratches to surfaces of the manufacture pieces can be avoided; the trimming die can be applied to trim manufacture pieces with arc borders; and burrs and scrap iron can be reduced during a punching process, cutting quality of trimming waste is improved, and the like.
Description
Technical field
The utility model relates to a kind of mould, especially relates to a kind of Trimming Die.
Background technology
In die industry, often the periphery at the protruding film of cutting edge is arranged symmetrically with two scrap cutters, utilizes the strength of punch press to make waste material produce shearing at scrap cutter, thereby waste material is cut off.Usually adopt at present common square scrap cutter, because the cutter piece of square scrap cutter is rectangular structure, periphery has corner angle, especially be that the product of circular arc is when contacting with the border, the contact effect is bad, corner angle easily and the product border interfere, not only affect the cut-out quality of deburring waste material, but also can cause the product surface to be pulled.
For example, Chinese patent Granted publication number: CN201768802U discloses a kind of novel diel material-removing structure March 23 2011 Granted publication day, aims to provide a kind of diel material-removing structure that can avoid producing in the punching course iron filings.The utility model is comprised of upper bolster, upper cavity die, die shoe, lower punch, counterdie scrap cutter piece, wherein upper cavity die by movable matrix cutter piece and fixedly die cutter piece form, movable matrix cutter piece is flexibly connected by retractable air-pressure device and upper bolster, along pressing direction guiding mechanism is set between movable matrix cutter piece and the upper bolster, the fixing fixedly die waste material cutting edge that matches with counterdie scrap cutter piece of die cutter piece setting, the cutting edge of movable matrix cutter piece is concordant with the cutting edge of fixing die cutter piece.Its weak point is, being not suitable for the border is that the product of circular arc carries out deburring, during deburring scrap cutter easily and the border of product interfere, affect the cut-out quality of deburring waste material and cause the product surface to be pulled.
The utility model content
The utility model be for the trimming die that overcomes prior art when the deburring corner angle on the scrap cutter easily and the border of product interfere, thereby affect the cut-out quality of deburring waste material, the deficiency that causes surface of the work to be pulled, provide a kind of scrap cutter to be difficult for interfering with the border of product, be applicable to the Trimming Die that the border is the product of circular arc.
To achieve these goals, the utility model is by the following technical solutions:
A kind of Trimming Die of the present utility model, comprise die shoe, be fixed on the side cut punch on the die shoe and be fixed on the trim die that matches with the side cut punch on the upper bolster, described Trimming Die also comprises the circular scrap cutter that is positioned at side cut punch both sides and is fixedly connected with die shoe, described circular scrap cutter is included as cylindrical cutter piece, described cutter piece top is provided with cutting edge, and described cutter piece bottom is fixedly connected with die shoe.Cylindrical scrap cutter does not have corner angle, be difficult for interfering with the border of product, can avoid the surface of product to be pulled by the corner angle on the cutter hub, especially be that the product of circular arc is when contacting with the border, the circular arc border of cylindrical cutter piece and product is external in the scrap cutter, be a linear contact, contact effectively, can guarantee the cut-out quality of deburring waste material.
As preferably, described cutting edge is in-line.Cutting edge is yi word pattern, makes the product uniform stressed when thrusting product, and cut-off part distortion is little, can greatly reduce the generation of burr and iron filings in the punching course, thereby improves the cut-out quality of deburring waste material.
As preferably, the cone-apex angle α on described cutter piece top is 45 ~ 90 °.On the die shoe of the iron filings that cone-apex angle can make generation bottom along the inclined-plane landing on the cutter hub to scrap cutter, avoid iron filings to be brought in the die with the motion of side cut punch mould is caused the quality of damaging or affecting product, cone-apex angle is excessive, iron filings are easily piled up on the cutter hub inclined-plane, cone-apex angle is too small, the compression strength of cutter hub is inadequate, 45 ~ 90 ° cone-apex angle can make the smooth landing of iron filings, also guaranteed the compression strength of cutter hub, cone-apex angle can also reduce the reconditioning quality of cutting edge simultaneously, improves its service life.
As preferably, described cutter piece bottom is provided with double-screw bolt, has the screw that matches with described double-screw bolt on the described die shoe, and described cutter piece is connected with die shoe with the cooperation of screw by double-screw bolt.Be threaded, be convenient to dismounting, can also regulate by rotation height and the position of the height adjusting cutting edge of cutter piece, to guarantee the cut-out quality of Trimming Die.
Therefore, the utlity model has following beneficial effect:
(1) scrap cutter is difficult for interfering with the border of product, can avoid the surface of product to pull;
(2) being applicable to the border is that the product of circular arc carries out deburring;
(3) can greatly reduce the generation of burr and iron filings in the punching course, improve the cut-out quality of deburring waste material.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the front view of circular scrap cutter in the utility model.
Fig. 3 is the left view of Fig. 2.
Among the figure: die shoe 1, side cut punch 2, upper bolster 3, trim die 4, cutter piece 5, cutting edge 6,
Double-screw bolt 7, screw 8.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Among the embodiment as shown in Figure 1, a kind of Trimming Die, comprise die shoe 1, be fixed on side cut punch 2 on the die shoe 1, be fixed on the trim die 4 that matches with side cut punch 2 on the upper bolster 3 and be positioned at side cut punch 2 both sides and have the circular scrap cutter (see figure 2) of cylinder cutter piece 5, the top of cutter piece 5 is the cutting edge 6 of in-line, and the cone-apex angle α on cutter piece 5 tops is 45 ~ 90 ° of (see figure 3)s, cutter piece 5 bottoms are fixed with double-screw bolt 7, have the screw 8 that matches with double-screw bolt 7 on the die shoe 1, cutter piece 5 is connected with die shoe 1 with the cooperation of screw 8 by double-screw bolt 7.
During use, only need double-screw bolt 7 with cutter piece 5 belows change over to and be arranged in the screw 8 that matches with double-screw bolt 7 on the die shoe 1, and cutting edge 6 gone to the position of trim die 4 is corresponding get final product, install very convenient.
