Specific embodiment
Below by specific embodiment and combine accompanying drawing the application is described in further detail.
As Figure 1-3, the embodiment of the present application provides a kind of bend punching die, for treating bending parts (for example
Steel plate 80) implement bending punching operation.
The bend punching die provided by the embodiment of the present application includes front die holder 10, rear die holder 20, Bending punch 30, binder
Plate 40, drift limited block 50, bending pole 60 and bending platform 70.
Bending punch 30 is arranged on front die holder 10, and front die holder 10 can include front template 100 and front mould fixed plate 101,
Front mould fixed plate 101 is fixed on front template 100, and Bending punch 30 is fixed by way of being fixed in front mould fixed plate 101
On front die holder 10.
Drift limited block 50 is arranged on rear die holder 20 with bending platform 70.Die holder 20 can include rear pattern plate 200 afterwards
With rear mold fixed plate 201, rear mold fixed plate 201 is fixed on rear pattern plate 200, and drift limited block 50 and bending platform 70 can be consolidated
It is scheduled in rear mold fixed plate 201.
Bending platform 70 treats bending parts for supporting.Cephacoria seat 10 can be moved with respect to holding pad 40, and then is driven
Bending punch 30 carries out ramming motion.Holding chamber is formed between bending platform 70 and holding pad 40, and holding chamber is waited to roll over for clamping
Curved parts, holding pad 40 be used for treat bending parts apply thrust treat bending parts to compress, and then realize treat
The fixation of bending parts.In the application, mounting groove 700 on bending platform 70, is provided with, bending pole 60 is arranged on mounting groove
In 700；Formed between bending pole 60 and mounting groove 700 and pair is rotated, rotate secondary rotatable around its axis for bending pole 60.
Bending pole 60 is arranged on the side of bending platform 70, for treating to form bending on bending parts after punching press
Place, forms punching press gap between drift limited block 50 and bending platform 70, punching press gap is positioned opposite with Bending punch 30, is pressed from both sides
Tight treat that bending parts need the top that the region of bending is located at punching press gap in clamping intracavity.
The bend punching die that the embodiment of the present application is provided is during work, and operator will first treat bending parts
It is placed on bending platform 70, then holding pad 40 is pressed in and treats on bending parts, so as to realize treating consolidating for bending parts
Fixed, before then driving, die holder 10 is moved, as on front die holder 10, therefore Bending punch 30 is arranged on, the mobile meeting of front die holder 10
Bending punch 30 is driven to carry out ramming motion, with the motion of Bending punch 30, be placed on clamping intracavity treats bending parts
30 punching press of drift is bent over positioned at the position at punching press gap top and realizes bending.
During pressing and bending, bending pole 60 treats bending zero installed in the side of bending platform 70 for being formed
Bending part of the part after punching press, bending pole 60 is arranged in the mounting groove 700 of bending platform 70, and bending pole 60 with
Formed between mounting groove 700 and pair is rotated, the rotation is secondary to supply bending pole 60 rotatable around its axis.Process in pressing and bending
In, bending pole 60 is arranged on the pressure concentration zones of bend punching die, and when the tensile force of bending is excessive, bending pole 60 can
To rotate, and then cause to treat the bending part material Uniform Tension of bending parts, due to tensile force when can eliminate bending punching press
The bending part cracking phenomena for causing is concentrated, meanwhile, during bending punching press, the rotation of bending pole 60 suitably can be adjusted
The uniform force of bending pole 60, it is to avoid a certain specific part of bending pole 60 is persistently subject to larger pressure, and then can keep away
Damaging occurs in the bending part for exempting from bend punching die.It can be seen that, the bend punching die that the embodiment of the present application is provided can be solved at present
