It is dynamic.
The elastomeric element being arranged on lower die holder or shaping mould is connected on the mold core, the elastomeric element is used for two
The reset of mold core keeps two mold core lower ends close in non-working condition phase.
The top of the shaping mould is fixedly installed for the baffle for wanting stamping parts to be positioned.
The rear of the shaping mould is provided with feed device, and the feed device includes that push rod is pushed away with what can be slid back and forth
Glassware, the feed device are arranged on the bracket for being fixedly connected on lower die holder, and the pusher connection push rod is placed in molding
On mould rear end in plane.Can be placed on the rear end face of shaping mould before wanting stamping parts punching press in this way, then by push rod by its
Be pushed into immediately below punch-pin, avoid because directly will stamping parts be placed on immediately below punch-pin caused by safety accident generation.
The feed device is connect with bracket by linear bearing.
The feed device further includes discharging box, and the front of pusher in plane on shaping mould is arranged in the discharging box, is put
The lower part of magazine is equipped with discharging seam, when pusher promotes, wants stamping parts to release from discharging seam for one of lowest part in discharging box
Immediately below to punch-pin, then push rod pulls pusher to retract original position.
The rear of the shaping mould, which is provided below, can slide back and forth lower part device, the lower part device by push rod push or with
Push rod connection.When blanking device is pushed ahead, the U-shaped part after punching press in forming cavity can be released into shaping mould.
The lower part device or（With）Pusher is connected with the elastomeric element resetted for it, the other end connection of elastomeric element
Lower die holder.
The lower part device is arranged on the bracket for being fixedly connected on lower die holder.
A kind of U-shaped part bending die tool described in the utility model should be adjusted and be set according to the material for wanting stamping parts before application
Set the reasonable falling stroke of punch-pin and speed.U-shaped part bending die tool described in the utility model is in use, first will stamping parts
Be put into discharging box, push push rod, pusher Forward will stamping parts be pushed into immediately below punch-pin, baffle can prevent from wanting stamping parts
It is fallen by pushing away, while lower part device also moves forward, the U-shaped part in die cavity is released into shaping mould, then pusher and lower part device automatically reply
It is in situ；Subsequent punch-pin falls, and for punch-pin when promotion wants stamping parts to fall to mold core lower part, continuing to fall separates mold core, mold core
When lower part separates, mold core top is inwardly squeezed, and completes the punching press and correction of U-shaped part, and then punch-pin, which rises, resets.
