Abstract
The utility model provides a step periphery has a cutting edge that deep -drawing cut off die, characterized by terrace die are big end down's stairstepping structure, above -mentioned less part is the deep -drawing section, its appearance is with to wait to process deep -drawing spare inner chamber identical, with the unilateral clearance of die for treating 1.15 times of processing material thickness, the major part is for the section of cutting edge below the terrace die, its appearance is with to wait to process deep -drawing spare appearance consistent, with the bilateral clearance of die for treating 8%-10% of processing material thickness, ladder department in the middle of the terrace die. In the use, the die is down, deep -drawing section above the terrace die will treat the processing material deep -drawing when required high, the side cut section below the terrace die forms required blanking clearance with the die and cuts off the edge. The deep -drawing is accomplished with cutting edge simultaneously, convenient operation, and product quality is reliable and stable, and production efficiency is high, and is with low costs.
Description
Technical field
The utility model relates to a kind of cold punching die of machining, particularly a kind of drawing edger.
Background technology
Drawing parts is easily because a variety of causes causes edge out-of-flatness in drawing process, and needing to carry out trimming, is generally utilize the plant equipment such as lathe, bead cutter to cut at present, and required trimming allowance is large, and production efficiency is low, and quality is unstable, and integrated cost is high.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, and provides a kind of drawing and trimming to complete simultaneously, stable and reliable product quality, the drawing edger that production efficiency is high.
The purpose of this utility model is achieved in that a kind of drawing edger, comprise punch, die, locator, push piece plate, push rod, push rod, die shoe, upper bolster, die shank, it is characterized in that punch is up-small and down-big ladder-type structure, smaller portions are drawing section above, its profile and drawing part inner chamber to be processed match, with 1.15 times that the monolateral gap of die is material thickness to be processed, below punch, major part is trimming section, its profile is consistent with drawing part profile to be processed, be 8% ~ 10% of material thickness to be processed with the bilateral gap of die, in the middle of punch, the step periphery at ladder place has blade.
The utility model is owing to adopting above design, the drawing section of punch and die form the drawing gap needed for drawing material, the trimming section of punch and die form required blade clearance, in using, die is with lathe slide block down, drawing section above punch by material drawing to be processed to desired height time, the trimming section below punch and die form required blade clearance and are cut off at edge.Drawing and trimming complete simultaneously, easy to operate, stable and reliable product quality, and production efficiency is high, and cost is low.
Accompanying drawing explanation
Fig. 1 is the utility model example structure schematic diagram.
Detailed description of the invention
Now illustrated embodiment makes detailed description to the utility model by reference to the accompanying drawings.
As shown in Figure 1, a kind of drawing edger, comprise punch 4, die 5, locator 3, push piece plate 6, push rod 9, push rod 2, die shoe 1, upper bolster 7, die shank 8, punch 4 is up-small and down-big ladder-type structure, smaller portions are drawing section above, its profile and drawing part inner chamber to be processed match, with 1.15 times that the monolateral gap of die 5 is material thickness to be processed, punch 4 below major part is trimming section, its profile is consistent with drawing part profile to be processed, be 8% ~ 10% of material thickness to be processed with the bilateral gap of die 5, the step periphery at the middle ladder place of punch 4 has blade.
