The utility model content
The purpose of this utility model provides a kind of loam cake riveting die, solves existing riveting die workpiece the location inconvenience is installed, and picks and places long problem of part time.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of loam cake riveting die, comprise the patrix that is connected with die shank, and counterdie is arranged on the caulking part that is used for laying riveting parts on the counterdie; Described caulking part comprises standing part and the movable part of flexible connection, standing part and movable part be encircled into one with the suitable cavity of loam cake riveted joint face.
For making things convenient for the workpiece dismounting, described movable part one end is overlapped on the standing part, and is flexibly connected by rotating shaft and standing part, and movable part is Unscrew around the shaft; The other end of movable part is locked with movable part and standing part by alignment pin.
Further, described alignment pin overcoat limited location cover, stop collar is fixed on the movable part, be provided with convenient manual push rod on the described alignment pin, have " L " type track groove on the stop collar, push rod stretches out in the track groove, also is provided with the first stage clip of control alignment pin return between push rod and movable part.
Preferably, described caulking part is arranged on the counterdie by two risers.
Further, described caulking part standing part is bolted on the riser, and movable part is pressed on the riser.
Further, for making things convenient for the taking-up of workpiece, also be provided with the positioning sleeve that cooperates with workpiece on the described counterdie, be provided with the second stage clip of control return in the positioning sleeve, workpiece is pressed on the second stage clip.
The beneficial effects of the utility model: the mode that caulking part adopts movable part and standing part to separate replaces integrated mode, by rotating shaft movable part is opened, put into workpiece, close again, workpiece can be put into from the side, do not need workpiece past transferring above cavity improved security when reducing the workload that picks and places workpiece, and simple in structure.Described locating pin structure makes things convenient for the locked of caulking part and opens, and opens and locked holding time weak point, improves production efficiency.Described the second stage clip and locating sleeve structure, the clamping and positioning of energy Effective Raise workpiece guarantees riveted joint accurately, simultaneously, the second stage clip makes things convenient for pickup.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
