of the length H of described backstay 4 more than or equal to upper punch 102.
Described predominant tube diameter φ D is 300 ~ 1200 millimeters, and being responsible for wall thickness T is 10 ~ 100 millimeters, and arm diameter phi d is 25 ~ 500 millimeters, and a thickness of pipe wall t is 3 ~ 50 millimeters.
The beneficial effect of the utility model:
The utility model is through increase body locating hole; Increase supplementary modes such as upper trimming die locating hole, drift locating hole and backstay and improve accuracy, the positioning time when having shortened punching greatly when locating; Significantly improve efficient, increased the qualification rate of product.
The utility model is simple in structure, makes easy for installationly, and the convenient quick precision in location is high.
