The beneficial effect that the utility model is reached：（1）Expanding die of the present utility model, in processing workpieces part
When, mould structure advantages of simple is easy to operate, is adapted to produce in batch.（2）The slope end face design of pressing block so that bulging
Workpiece afterwards is uniform.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
The implication of reference in figure：1st, left die, 2, upper lock module, 3, loading and unloading material bar, 4, top board, 5, upper bolster,
6th, upper punch, 7, upper pressing block, 8, workpiece, 9, polyester ammonia block, 10, right die, 1-1, left handle, 7-1, ear block.
Specific embodiment
The utility model is further described below in conjunction with the accompanying drawings.Following examples are only used for clearly illustrating this
The technical scheme of utility model, and protection domain of the present utility model can not be limited with this.
Participation Fig. 1, expanding die of the present utility model,
A kind of cylindrical tube expansion mould, including upper bolster 5, die shoe, pressing block, polyester ammonia block 9, die, discharge arm, locked mode
Block, drift, pressing plate, die includes the left die 1 and right die 10 of full symmetric mirror image, and left and right two die 1,10 is all distinguished
It is that upper and lower mirror image is arranged, discharge arm includes loading and unloading material bar 3 and lower discharge arm, lock module includes upper lock module 2 and lower lock module, pressure
Plate includes top board 4 and lower platen, and drift includes upper punch 6 and low punch, and pressing block includes upper pressing block 7 and lower pressing block,
Upper bolster 5, loading and unloading material bar 3, upper lock module 2, top board 4, upper punch 6, upper pressing block 7 respectively all with die shoe, lower discharge arm,
The upper and lower mirror image of lower lock module, lower platen, low punch, lower pressing block is arranged；Top board 4 is fixedly connected with upper bolster 5, upper lock module
2 are flexibly connected by loading and unloading material bar 3 with top board 4, and upper punch 6 is fixedly connected with upper bolster 5, and upper pressing block 7 passes through ear block 7-1
It is fixedly connected with top board 4, polyester ammonia block 9 is positioned in the inner chamber formed after left and right die 1,10 matched moulds, for the ease of will be into
Workpiece 8 after type takes out from die, and die is divided into into two pieces of left and right, and workpiece to be processed is laterally zygomorphic tubular.
The lower surface of upper punch 6 is slope end face, and the upper surface of upper pressing block 7 is oblique with what the lower surface of upper punch 6 matched
Slope end face, 2 slope end faces for matching are designed and cause the wall thickness of workpiece 8 for forming out more uniform.
The middle part of loading and unloading material bar 3 is coated with spring, the setting not only effect of reset of spring, it is often more important that, in punching press
During, apply pressure and promote the firm left and right die 1,10 of locking of upper lock module 2.
The inner chamber of upper lock module 2 is taper type, and the design of taper type causes lock module 2 to contact with left and right die 1,10
Area increases, and increasing friction force, it is often more important that because profile is back taper itself can be very good to play positioning action.
The workpiece after shaping is taken out for convenience, and left handle 1-1 and right handles are all provided with left and right die 1,10, it is left
Handle 1-1 and right handles are left and right mirror-image arrangement.
Expanding die of the present utility model, its specific work process is as follows：
When upper bolster 5 is descending, die shoe is up, drive that top board 4 is descending, lower platen is up respectively, upper lock module 2 will be recessed
Molding is lower and locks, and lower lock module pushes against die, and upper bolster 5 is continued traveling downwardly, die shoe continues up, in the contact of upper punch 6
The lower pressing block of pressing block 7, low punch contact, and the slope end face of the lower end of upper punch 6 slowly with the slope end face of upper pressing block 7
Intersecting, the slope end face of low punch upper end intersects with the slope end face of lower pressing block slowly, common compressed polyester ammonia block 3, into
Workpiece 8 of the type wall portion with dome.After shaping, upper bolster 5 is up, die shoe is descending, and top board 4 is up, lower platen is descending, lifts
Two handles on left and right die 1,10, left and right die 1,10 is broken into two with one's hands slightly, subsequently takes out the workpiece 8 after shaping.
The utility model the above be only preferred embodiment of the present utility model, it is noted that for this technology neck
For the those of ordinary skill in domain, on the premise of without departing from the utility model know-why, can also make it is some improvement and
Deformation, these are improved and deformation also should be regarded as protection domain of the present utility model.
