Description
Technical field
The utility model is related to a kind of special-shaped workpieces to rush three punch dies, belong to Stamping Die Technology field.
Background technology
In the production of auto parts and components, be frequently encountered the workpiece punching of the punching processing of shaped piece, especially tear open it is more
The hole of a different location and size position.It is illustrated in figure 4 a kind of outer skeleton of automobile top connection board, in the bowl-shape knot of abnormity
Structure, there are three hole positions for punching.Existing processing method is punching one by one, and processing efficiency is low, and hole position precision is difficult to ensure, is deposited
In deficiency.
Utility model content
Against the above deficiency, the utility model provides a kind of special-shaped workpiece punching three punch dies.
The technical solution of the utility model is：
Three punch dies of a kind of special-shaped workpiece punching comprising upper mold and lower die.
The upper mold includes top mold frame, is arranged in the punch fixing plate of top mold frame lower end and setting on punch fixing plate
Three punches；The lower end of the punch fixing plate is equipped with polyurethane block and dnockout block, and the front end of the punch is through described poly-
Urethane block and dnockout block.
The lower die includes that the bottom-up pedestal set gradually, lower die cushion block, lower template, lower mold fixed plate, workpiece are fixed
Position plate and three cavity plate mold inserts in lower mold fixed plate；The upper end of the cavity plate mold insert is through to the workpiece positioning
The upper surface of plate；The lower template is equipped with blanking through-hole, and the die hole of the blanking through-hole and the cavity plate mold insert penetrates through.
The beneficial effects of the utility model are：The utility model is once punched three holes, high in machining efficiency, punching precision
It is high；Equipped with workpiece positioning plate, the accuracy and punching precision of workpiece positioning ensure that；Punching concave die uses insert structure, is convenient for
Cavity plate is replaced when different pore size punching processing.
