Description
Technical Field
The utility model relates to the technical field of continuous dies, in particular to a die positioning mechanism for a stamping drawing piece.
Background
With the development of die technology, the production process of the continuous stamping die is mature day by day, and the stretching piece is produced by adopting the stamping continuous die, so that the production process can be simplified, the production efficiency is improved, and the stability of the product is improved, thereby being widely applied. However, after the stamping part is continuously stretched, due to the fact that stretching causes material shrinkage deformation, the relative size of the stretching part and the material belt positioning hole deviates, and therefore, the precision is not high in the traditional stamping continuous die positioning mode of positioning the positioning needle on the profiling die and the positioning hole on the material belt, and the positioning requirement of the high-precision stretching part cannot be met, and therefore the problem needs to be solved by designing the in-die positioning mechanism of the stamping stretching part.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a die positioning mechanism for a stamping and stretching piece, which overcomes the defects in the prior art.
In order to achieve the purpose, the utility model adopts the following technical scheme:
the utility model provides a punching press extension piece in-mold positioning mechanism, includes mould and lower mould, go up the mould and include that the mould pushes down the mechanism, set up the spring that pushes down under the mechanism, set up the push rod under the spring, set up the punching pin under the push rod, set up the pressure ram under the punching pin.
Preferably, the diameter of the swaging rod is smaller than that of the punch.
Preferably, the length of the material pressing rod is smaller than that of the punch.
Preferably, the swaging rod is arranged at the punching end of the punch.
The beneficial effects of the utility model are: according to the utility model, the relative position of the die and the stretching piece is fixed through the positioning structure, and then the subsequent process is carried out, so that the problem of the positioning precision in the die of the stretching piece is solved, the dimensional precision of the stretched product is improved, the production cost is reduced, and the production efficiency of the stretching piece is improved.

FIG. 1 is a schematic structural view of a die positioning mechanism of a stamping and drawing part according to the present invention;
FIG. 2 is a diagram of an embodiment of a die positioning mechanism for a stamped and drawn part according to the present invention;
in the figure: 1. a mold pressing mechanism; 2. a spring; 3. a push rod; 4. punching; 5. a material pressing rod; 6. an upper die; 7. a lower die; 8. a tension member; 9. and (5) chamfering the punch.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, are used in the orientations and positional relationships indicated in the drawings, which are based on the orientations and positional relationships indicated in the drawings, and are used for convenience of description and simplicity of description, but do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention.
Referring to fig. 1, the present embodiment is a die positioning mechanism for a stamping and stretching piece, and the die positioning mechanism includes an upper die 6 and a lower die 7, where the upper die includes a die pressing mechanism 1, a spring 2 disposed below the die pressing mechanism, a push rod 3 disposed below the spring, a punch 4 disposed below the push rod, and a material pressing rod 5 disposed below the punch.
The diameter of the material pressing rod is smaller than that of the punch. The length of the material pressing rod is smaller than that of the punch. The material pressing rod is arranged at the punching end of the punch. The diameter of pressing the material pole is less than the punching pin and just can effectual cooperation punching pin punching press, and the length of pressing the material pole need not too long, only need earlier with tensile piece inner wall fix reach the effect of location can, set up the punching press end at the punching pin just can contact earlier with tensile piece, fix a position. The punch can be replaced according to the requirement, and is suitable for punching different punches.
In this embodiment 1, referring to fig. 2, in a free state, the spring presses the push rod, and the pressing rod extends out. In the die closing process of descending the die, the material pressing rod firstly enters a stretched product, and the center position of the stretched piece is fixed by the side surface of the head of the material pressing rod and the inner wall of the stretched piece 8, so that the purpose of positioning is achieved. The die continues to move downwards, the pressing head presses the bottom plane of the stretching piece under the action of the elastic force of the spring, the die continues to move downwards, the chamfering punch 9 also moves downwards along with the pressing head, and finally the chamfering punch is contacted with the cup opening of the stretching piece to complete chamfering.
In this embodiment 2, in a free state, the spring presses the push rod, and the pressing rod extends out. In the die closing process of descending the die, the material pressing rod firstly enters a stretched product, and the central position of the stretched piece is fixed by the side surface of the head of the material pressing rod and the inner wall of the stretched piece, so that the purpose of positioning is achieved. And (3) the die continues to move downwards, the material pressing head presses the bottom plane of the drawing piece under the action of the elastic force of the spring, the die continues to move downwards, the discharging punch also moves downwards along with the die and finally contacts with the cup opening of the drawing piece, the discharging punch discharges the material, and the material falls onto a product to finish discharging.
The die has the advantages that the relative positions of the die and the stretching piece are fixed through the positioning structure of the stamping stretching piece, and then the subsequent process is carried out, so that the problem of the positioning precision in the die of the stretching piece is solved, the dimensional precision of the stretched product is improved, the production cost is reduced, and the production efficiency of the stretching piece is improved.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and equivalent alternatives or modifications according to the technical solution of the present invention and the inventive concept thereof should be covered by the scope of the present invention.
