Abstract
The utility model relates to a tensile stamping die of circular thick material, include upper die base, upper padding plate, punch holder, take off the flitch, the die holder, the upper die base below sets gradually upper padding plate, punch holder, punch holder center department has the tensile drift of a columniform, the punch holder takes off the flitch through spring post fixed connection, the flitch bottom of taking off of tensile drift below has the punching press groove, and simultaneously, punch holder middle part and the tensile adjacent department of drift add a drawing towards the needle and the spring beam is passed through towards the needle to this drawing fixes on the upper die base, die holder top center department has die down. The utility model discloses beneficial effect does: through fixing the tensile drift on the punch holder and fixing the tensile die on the lower bolster, through tensile, plastic many times to reach the product tolerance requirement, combine drawing towards needle simultaneously, improve the precision and the production work efficiency of product.
Description
Technical field
The utility model relates to Stamping Die Technology, particularly relates to a kind of circular thick material stretching and punching mould.
Background technology
Along with developing rapidly of national economy, diel industry plays more and more consequence in daily life, and the production efficiency of punch process is high, easy to operate, conveniently realizes mechanization, automation; During punching press, mould ensure that the size and shape precision of stamping parts, does not generally destroy the surface quality of stamping parts, and the life-span of mould longer, stamping quality is stable, interchangeability is good, the feature with " striking resemblances "; Punching press can process larger size range, complex-shaped part, and makes material have flow harden effect during punching press, and the strength and stiffness of punching press are all higher; Stamping material utilization rate is higher, and the cost of stamping parts is lower.
The structure type of punch die is a lot.Blanking die, bending die, Drawing Die, shape mould etc. can be divided into by operation character; Single die, compound die, progressive die etc. are divided into by process step combinations mode.No matter the diel of what type can be divided into upper die and lower die two parts composition, patrix is fixed on press bench, during work, blank is located by position part on counterdie, and press ram drives patrix to press down, and produces and be separated and plastic deformation under the effect of mould punch-die, thus when obtaining the stamping parts of definite shape and size, when press ram backhaul, waste material rushes on convex concave mould and unloads down by shedding mechanism, thus enters press cycle next time.
The part of punch process is of a great variety, and part shape, size and required precision are different, and in thus producing, Sheet Metal Forming Technology method is also varied.Generally speaking, separation circuit and the large class of forming process two is divided into; Separation circuit is the operation that the stamping parts of instigating blank to obtain definite shape, size and cross section quality along the separation of certain outline line is commonly called as blanking part; Forming process is that blank produces the distortion of plasticity thus obtains the operation of the stamping parts of certain size under condition of not breaking.This two classes operation, be divided into again four kinds of basic working procedure such as stamping-out, bending, drawing, shape mould by basic deformation mode difference, often kind of basic working procedure is again containing many single operations.
This case is it is important to note that when carrying out round thick material punching press, and traditional turnery just can reach product tolerance requirement, multi-drawing and shaping cannot be realized for the thick material of circle, also cannot reach product tolerance requirement, meanwhile, the cooperation between upper and lower mould lacks the specific aim of mould.
Therefore, for above aspect, need reasonably to improve prior art.
Utility model content
For above defect, the utility model provides a kind of being conducive to reach product tolerance requirement, improve the precision of product and the circle thick material stretching and punching mould of production work efficiency, to solve many deficiencies of prior art.
For achieving the above object, the utility model is by the following technical solutions:
A kind of circular thick material stretching and punching mould, comprise upper bolster, upper padding plate, train wheel bridge, stripper plate, die shoe, upper padding plate, train wheel bridge is set gradually below described upper bolster, described train wheel bridge center is with a columniform draw punch, described train wheel bridge is fixedly connected with stripper plate by spring stack, with stamped groove bottom the stripper plate below described draw punch; Meanwhile, a stretching red needle is set up with draw punch adjacent in the middle part of described train wheel bridge and this stretching red needle is fixed on upper bolster by spring lever; Described die shoe top center place is with lower cavity die.
Described stripper plate top arranges de-backing plate, is fixed on die shoe bottom described lower cavity die by spring spindle.
The beneficial effect of circle described in the utility model thick material stretching and punching mould is: by the draw punch be fixed on train wheel bridge and the stretching die be fixed on lower bolster, through multi-drawing, shaping, thus reach product tolerance requirement, simultaneously in conjunction with stretching red needle, improve precision and the production work efficiency of product.
Accompanying drawing explanation
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the structural representation of circular thick material stretching and punching mould described in the utility model embodiment.
In figure:
1, upper bolster; 2, upper padding plate; 3, train wheel bridge; 4, de-backing plate; 5, stripper plate; 6, die shoe; 7, spring stack; 8, draw punch; 9, stretching red needle; 10, lower cavity die; 11, stamped groove; 12, spring spindle.
Detailed description of the invention
As shown in Figure 1, circle described in the utility model embodiment thick material stretching and punching mould, comprise upper bolster 1, upper padding plate 2, train wheel bridge 3, stripper plate 5, die shoe 6, upper padding plate 2, train wheel bridge 3 is set gradually below described upper bolster 1, train wheel bridge 3 center is wherein with a columniform draw punch 8, described train wheel bridge 3 is fixedly connected with stripper plate 5 by spring stack 7 and arranges de-backing plate 4 at stripper plate 5 top, with stamped groove 11 bottom the stripper plate 5 below described draw punch 8; Meanwhile, a stretching red needle 9 is set up with draw punch 8 adjacent in the middle part of described train wheel bridge 3 and this stretching red needle 9 is fixed on upper bolster 1 by spring lever;
Correspondingly, described die shoe 6 top center place is fixed on die shoe 6 by spring spindle 12 bottom this lower cavity die 10 with lower cavity die 10.
Circle thick material stretching and punching mould described in above the utility model embodiment, when mould punching is shaped, by the draw punch be fixed on train wheel bridge and the stretching die be fixed on lower bolster, through multi-drawing, shaping thus reach product tolerance requirement, improves precision and the production work efficiency of product.
The above-mentioned description to embodiment can understand and apply this case technology for the ease of those skilled in the art, person skilled in the art obviously can make various amendment to these examples easily, and General Principle described herein is applied in other embodiment and need not through performing creative labour.Therefore, this case is not limited to above embodiment, and those skilled in the art is according to the announcement of this case, and the improvement made for this case and amendment all should in the protection domains of this case.
