Description
Technical field
The utility model relates to mould applications, especially a kind of special-shaped U-shaped snap close shaping mould upper slitter.
Background technology
Mould makes blank become the instrument of the product having given shape and size under external force.Be widely used in stamping-out, die forging, cold-heading, extruding, metallic sintered products compacting, compression casting, and in the compression moulding of goods such as engineering plastics, rubber, pottery or the formed machining of injection moulding.Mould has specific profile or cavity shape, and the contour shape that application has cutting edge can make blank be separated (stamping-out) by outline line shape.Application cavity shape can make blank obtain corresponding three-dimensional shape.Mould generally comprises dynamic model and cover half (or punch and die) two parts, the two partable.Take out product time separately, make blank inject mold cavity when closing up and be shaped.Mould is precision instrument, complex-shaped, bears the expansive force of blank, all has higher requirements to structural strength, rigidity, case hardness, surface roughness and machining accuracy, and the development level that mould is produced is one of important symbol of machine-building level.Technique when carrying out processing and forming to the U-shaped snap close of routine is: cut off bending---cold-heading---and revolve riveting.But to the special-shaped U-shaped snap close of one, because the length of snap close U-shaped part two legs is inconsistent, when carrying out bending, production requirement is met to the length requirement of two legs of the semi worked pieces being bent into U-shaped, check and accept if workpiece is taken out bending equipment to carry out measurement, operation increase, complex operation.
Summary of the invention
The technical problem that the utility model solves is to provide the one special-shaped U-shaped snap close shaping mould upper slitter being applicable to special-shaped U-shaped snap close and producing.
The technical scheme in the invention for solving the technical problem is: a kind of special-shaped U-shaped snap close shaping mould upper slitter, comprise upper slitter main body, the top of described upper slitter main body is provided with fixed part, the upper surface in fixed portion offers two installing holes, the centre of described upper slitter main body is connecting portion, described connecting portion is provided with three road deep-slotted chip breakers, the below of described connecting portion is bending part, described bending part is by the edge of a knife, transition face forms, the bottom of described bending part is the semicircular edge of a knife, it is transition face between the described edge of a knife and connecting portion, described transition face is tilted to down.
Further, the outside of the upper surface in fixed portion is provided with chamfering.
Further, the radius of described deep-slotted chip breaker is 1.5mm, and the degree of depth of described deep-slotted chip breaker is 0.8mm.
Further, described transition face is 30 ° at the angle of inclination of vertical direction.
The beneficial effects of the utility model are: the utility model is applicable to the production of special-shaped U-shaped snap close, for the left and right leg of the different length of U-shaped part, can be judged the length of leg by connecting portion Shang tri-road deep-slotted chip breaker, convenient for production, quick.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is the utility model structural representation.
Detailed description of the invention
The special-shaped U-shaped snap close of one as shown in Figure 1 shaping mould upper slitter, comprise upper slitter main body 1, the top of described upper slitter main body 1 is provided with fixed part 2, the upper surface in fixed portion 2 offers two installing holes 21, the centre of described upper slitter main body 1 is connecting portion 3, described connecting portion 3 is provided with three road deep-slotted chip breakers 31, the below of described connecting portion 3 is bending part 4, described bending part 4 is made up of the edge of a knife 41, transition face 42, the bottom of described bending part 4 is the semicircular edge of a knife 41, be transition face 42 between the described edge of a knife 41 and connecting portion 3, described transition face 42 is tilted to down.
Further, the outside of the upper surface in fixed portion 2 is provided with chamfering.
Further, the radius of described deep-slotted chip breaker 31 is 1.5mm, and the degree of depth of described deep-slotted chip breaker 31 is 0.8mm.
Further, described transition face 42 is 30 ° at the angle of inclination of vertical direction.
It is emphasized that, it is more than better implementation column of the present utility model, not any type of restriction is done in appearance to utility model, every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
