Abstract
The utility model relates to a side hole flanging die, which comprises an upper die and a lower die. The upper die comprises a hole flanging female die in flexible connection with a pressing block and in cooperation with a hole flanging male die for molding the side flange of an article. By using arranging structure that the hole flanging female die is in flexible connection with the pressing block on an upper die seat, the hole flanged female die does not need to generate greater stroke along the article length direction on the lower die during the material returning process. Therefore, the side flanges of various articles can made completed without replacing a tapered wedge guide board structure and other die structures to reduce cost.
Description
Technical field
The utility model relates to the diel field, relates in particular to a kind of diel with rollover hole function.
Background technology
In the stamping forming whole operation of product process mould, a lot of products need carry out punching, publication number " CN 2843826 " name is called " the punching stretching composite die that is used for NC turret punch machine " and discloses a kind of punching stretching composite die that is used for the punching operation in China's utility model application prospectus, it is characterized in that: described patrix comprises the height adjusting nut, the height adjusting nut connects the screw rod of a hollow, the screw rod lower end connects the hole flanging guide way through attachment screw, one piercing punch axially stretches into from bottom to top and is fixed in the hole flanging guide way, described piercing punch lower limb periphery is provided with the hole flanging material returning sleeve that matches with piercing punch, hole flanging material returning sleeve periphery is provided with the hole flanging upper cavity die edge of a knife of annular, the hole flanging upper cavity die edge of a knife and hole flanging guide way fix, hole flanging material returning sleeve top is provided with and allows the hole flanging material returning sleeve to make a concession the material returned cavity of action, the hole flanging material returning sleeve is provided with guide post, guide post passes the hole flanging guide way from the top down fixedlys connected with the hole flanging material returning sleeve, the root of guide post is conflicted on the thrust block pad of horizontal positioned on the hole flanging guide way upside, cavity in thrust block pad periphery and the screw rod matches, being provided with patrix material returned spring in the cavity in the screw rod, conflicts on thrust block pad in patrix material returned spring lower end; Described counterdie comprises the lower mold body that is provided with centre bore, and centre bore upper end inner edge is provided with the internal diameter and the suitable counterdie punching edge of a knife of piercing punch external diameter; The lower mold body of centre bore periphery extends upward to a boss, the internal diameter of the described boss external diameter and the hole flanging upper cavity die edge of a knife is suitable, boss is socketed with stripper outward, the stripper periphery is provided with the guard ring that fixes with lower mold body, be provided with some counterdie material returned springs between stripper and the lower mold body, described counterdie material returned spring is distributed in the boss periphery.
The punching stretching composite die of said structure just is applicable in the short transverse of product and carries out hole flanging; And since some product need carry out the outside hole flanging of side direction at its length direction, as the fuel tank of vehicle body; Adopt said structure can't finish and carry out the side direction hole flanging at the product length direction, the existing side direction hole flanging mould that carries out, its hole flanging die is by the wedge guide plate structure flexible connection on spring and the die shoe, when carrying out the side direction hole flanging, the hole flanging die is under the drive of wedge guide plate structure, along the side-to-side movement of product length direction,, cooperate moulding side direction hole flanging with the hole flanging punch that is connected on the die shoe; But, because after hole flanging is finished, the hole flanging die need withdraw from product fully, owing to adopt this kind structure after some product hole flanging is finished in the material returned process, the hole flanging die is very big along the material returned stroke of product length direction, surpassed the stroke that common wedge guide plate structure can provide, adopt existing side direction hole flanging mould that all types of products are carried out the side direction hole flanging as can be seen, must change the wedge guide plate and the spring that is used for flexible connection hole flanging die and wedge guide plate of various corresponding product sizes, the inevitable like this manufacturing cost that increase mould greatly.
The utility model content
