Description
Technical field
The present invention relates to a kind of diel and process for stamping thereof, particularly relate to a kind of diel and process for stamping thereof of flange nut.
Background technology
As depicted in figs. 1 and 2, the diel 1 ' of existing flange nut comprises punch 11 ', die 12 ' and top cover 13 '.Punch 11 ' and die 12 ' corresponding matching, punch 11 ' has body 111 ', and the end of body 111 ' forms reducing diameter part 112 '; The die cavity 121 ' that has hexagonal flange nut shape in the die 12 '; Top cover 13 ' is the solid cylinder suitable with die cavity 121 '; The middle part of cover 13 ' one end, top caves inward and forms the groove 131 ' of placing solid blanks materials and parts 2 ' in order to the location, and top cover 13 ' is arranged in the die 12 ', during punching press solid blanks materials and parts 2 ' just in time is placed on groove 131 ' and locates.
As shown in Figure 3; Utilize diel 1 ' punching press hexagonal flange nut; Realize through following steps successively: the groove 131 ' of cover 13 ' locates to place solid blanks materials and parts 2 ' on the top; Punch 11 ' is stamped in the die cavity 121 ' of die 12 ', thereby solid blanks materials and parts 2 ' are washed into blank 20 '.
But, adopt existing diel 1 ' can not once go out hollow pipe fitting with holes with process for stamping; Compare blank 20 ' the cap shape that is as shown in Figure 2, the cap portion 22 ' that has ring flange 21 ' and protrude with final finished product hexagonal flange nut; After punch steps, just need extra increase to remove the operation of cap portion 22 ' together like this; And the ring flange 21 ' of blank 2 ' all has very thick thickness with cap portion 22 '; Waste the blank about 40% on the one hand; Also increased the processing capacity at the shaping of back road, trimming angle etc. on the other hand, the invisible difficulty of processing that increased has influence on crudy.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of diel of saving the flange nut of blank.
The objective of the invention is to also provide a kind of process for stamping of saving the flange nut of blank.
In order to reach above-mentioned purpose, solution of the present invention is:
A kind of diel of flange nut comprises the punch and the die of corresponding matching, and is arranged in the top cover in this die; Has the die cavity that is washed into flange nut in this die; The end of said top cover is provided with recess, and said punch has body, and this body is provided with reducing diameter part towards an end of above-mentioned die; Be connected through a chamfered section between this reducing diameter part and this body, the end of this reducing diameter part and this recess are sheathed each other.
Said reducing diameter part and said the recess sheathed degree of depth each other are 3mm-15mm.
Said reducing diameter part of the depth ratio of said recess and said recess be the sheathed dark 5mm-15mm of the degree of depth each other.
Said top cover is for having the sleeve-like of through hole.
Said die cavity is and the corresponding die cavity of hexagonal flange nut that said top cover is and suitable positive six prisms of said die cavity.
Another solution of the present invention is:
1), the said diel in hollow blank materials and parts and the such scheme is provided a kind of process for stamping of flange nut is realized through following steps: successively; 2), with said diel and the preheating of said hollow blank materials and parts, then said hollow blank materials and parts are placed the said indent of the cover end, said top of said die; 3), said punch is stamped in the said die, make said hollow blank materials and parts be stamped into the blank with the flange nut structural similarity; 4), said blank is taken out in die sinking.
Said hollow blank materials and parts are the metal copper pipe.
After adopting said structure, the diel of flange nut of the present invention has following beneficial effect:
One, the top is set in the die, and the hollow blank materials and parts are placed on the jagged end of top tackling, and punch is stamped into the die cavity of die, and the hollow blank materials and parts are struck out flange nut; Because the end of top cover has recess, therefore can adopt the hollow blank materials and parts to carry out punch process, adopt the solid blanks materials and parts to compare with existing diel, both reduced the operation of removing " cap portion " together, can practice thrift blank again up to about 50%; Punch is stamped in the die cavity of die; The hollow blank materials and parts that are placed on cover end, top are struck out semi-finished product; Utilize its end recesses location to be prone to cause dislocation and frequently to cause the structure of substandard products to be compared with existing top cover, the top cover among the present invention is easier to place the hollow blank materials and parts, and punch process can be carried out in the end that only needs the hollow blank materials and parts to be placed on the top cover; Can realize fast positioning action accurately, help enhancing productivity and yield rate; Punch is mutually sheathed with the recess of top cover, and directly the punching press contact is few, has prolonged the service life of diel, can stand the punch process up to 180,000 times-200,000 times; The chamfered section that is connected with reducing diameter part makes the hollow blank materials and parts form good punching press distortion in the punching course of punch, can strike out thin flange nut semi-finished product, has reduced the processing capacity that redundance is removed in back road; In a word, compare with existing semi-finished product blank with thicker ring flange and cap portion, the semi-finished product with the flange nut structural similarity that the present invention was washed into are thinner, help the processing of road, back, both reduced difficulty of processing, improved crudy again;
Two, the mutual sheathed degree of depth of reducing diameter part and recess is 3mm-15mm, can be washed into the high-quality semi-finished product more approaching with the finished product flange nut, and the processing capacity of half-finished removal redundance is less, has reduced the processing capacity of the shaping of back road, finishing;
Three, the mutual sheathed dark 5mm-15mm of the degree of depth of the depth ratio reducing diameter part of recess and recess; Like this; Can guarantee the effective extensional of hollow blank materials and parts space on the one hand; Can also limit the too much distortion of hollow blank materials and parts on the other hand, thereby be washed into the high-quality semi-finished product close with the finished product flange nut; The sheathed precision of reducing diameter part and recess be can also guarantee in addition, the load-carrying properties of cover and the service life of diel guaranteed to push up.
After adopting such scheme; The process for stamping of flange nut of the present invention has following beneficial effect: adopt the solid blanks materials and parts to compare with existing diel; The present invention strikes out the semi-finished product with the flange nut structural similarity with the hollow blank materials and parts, can practice thrift the blank up to about 50%; Punch is stamped in the die cavity of die; The hollow blank materials and parts that are placed on cover end, top are struck out semi-finished product; Utilize its end recesses location to be prone to cause dislocation and frequently to cause the structure of substandard products to be compared with existing top cover, the top cover among the present invention is easier to place the hollow blank materials and parts, and punch process can be carried out in the end that only needs the hollow blank materials and parts to be placed on the top cover; Can realize fast positioning action accurately, help improving yield rate; Punch is mutually sheathed with the recess of top cover, and directly the punching press contact is few, has prolonged the service life of diel, can stand the punch process up to 180,000 times-200,000 times; The chamfered section that is connected with reducing diameter part makes the hollow blank materials and parts form good punching press distortion in the punching course of punch, can strike out thin flange nut semi-finished product, has reduced the processing capacity that redundance is removed in back road; In a word, compare with existing semi-finished product blank with thicker ring flange and cap portion, the present invention can be washed into the thin semi-finished product with the flange nut structural similarity, helps the processing of road, back, has not only reduced difficulty of processing but also improved crudy.
