Surely.
Further improvement is that upper clamp upper end is rotatably connected on locking upper arm one end by joint shaft；Upper clamp is with
The opposite face of clamp sets hackle mark；Pressure sensor, the signal transmission of pressure sensor are set in upper clamp and lower clamp
To control device, control device controls the operating of clamping cylinder.Wherein upper clamp is rotatably connected on the lower end of locking upper arm, is drawing
The friction to plate is reduced when stretching, hackle mark is set in the opposite face of upper clamp and lower clamp in addition so that the clamping force of plate
Degree is more preferable, avoids skidding；Pressure sensor can avoid the pressure of upper clamp and lower clamp excessive, cause sheet metal stretching to deform.
In more curved surface formings, a kind of rotatable hydraulic pressure feeding clip mechanism with self-locking is developed so that material folding the more is pressed from both sides the more tight,
Thoroughly solve the situation for clamping and skidding being clamped in section bar and sheet metal stretching, and appoint with gripping angle is stretched regardless of workpiece material
Meaning is different, the function that clamping mechanism can be also servo-actuated with clamp base axle center.
A kind of rotatable hydraulic pressure feeding clip mechanism with self-locking of the present utility model, has the beneficial effect that：
1st, the feeding clip mechanism makes curved surface forming sheet metal thickness be expanded to 0.5 ㎜ -5 ㎜；
2nd, the feeding clip mechanism compresses positioning using edges of boards, ensure that product in machining accuracy qualification rate up to 98.5%.

Embodiment
Describe optimal technical scheme of the present utility model in detail below in conjunction with the accompanying drawings.
As illustrated, a kind of rotatable hydraulic pressure feeding clip mechanism with self-locking of the present utility model, including upper clamp 1 and lower folder
Pincers 2, upper clamp 1 and lower clamp are oppositely arranged about 2, plate 3 to be processed between upper clamp 1 and lower clamp 2, and on
Clamp 1 is arranged on locking upper arm 6, and lower clamp 2 is arranged on locking underarm 4, is passed through among locking upper arm 6 and locking underarm 4
Joint shaft 7 is rotatablely connected, and the other end of locking upper arm 6 and locking underarm 4 is rotatablely connected clamp galianconism 8 respectively, and two clamps are short
The other end of arm 8 is rotatably connected on clamp base 9, in rotating joint and the locking upper arm 6 and locking underarm of clamp base 9
Clamping cylinder 5 is set between 4 rotating joint.
Wherein preferable, the other end of locking upper arm 6 and locking underarm 4 is short by the rotation connection clamp of joint shaft 7 respectively
Arm 8, the other end of two clamp galianconism 8 are rotatably connected in the same run-on point of clamp base 9 by joint shaft 7；It is described
Clamping cylinder 5 is hydraulic jack.
Further, the upper end of upper clamp 1 is rotatably connected on locking upper arm 6 one end by joint shaft 7；Upper clamp 1 and lower folder
The opposite face of pincers 2 sets hackle mark；Pressure sensor, the signal transmission of pressure sensor are set in upper clamp 1 and lower clamp 2
To control device, control device controls the operating of clamping cylinder 5.
A kind of rotatable hydraulic pressure feeding clip mechanism with self-locking of the present utility model, whole mechanism are rotatably connected on clamp base
On, can opposed jaws base rotation any angle, in addition the clamping of upper clamp and lower clamp by clamping cylinder drive clamp, and
And in the drawing process of plate, upper clamp and lower clamp the more can press from both sides the more tight, thoroughly solve and clamp section bar and sheet metal stretching mistake
The situation of skidding is clamped in journey.
The setting of joint shaft make it that the rotation of each run-on point is more smooth, and rotates flexibly, and joint shaft is provided with
Clamp galianconism is driven beneficial to clamping cylinder and is locked upper arm and is locked the rotation of underarm；The work of hydraulic jack is more steady.
Wherein upper clamp is rotatably connected on the lower end of locking upper arm, the friction to plate is reduced in stretching, in addition upper
Clamp and the opposite face of lower clamp set hackle mark so that the clamping dynamics of plate is more preferable, avoids skidding；Pressure sensor can be with
Avoid the pressure of upper clamp and lower clamp excessive, cause sheet metal stretching to deform.
In more curved surface formings, a kind of rotatable hydraulic pressure feeding clip mechanism with self-locking is developed so that material folding the more is pressed from both sides the more tight,
Thoroughly solve the situation for clamping and skidding being clamped in section bar and sheet metal stretching, and appoint with gripping angle is stretched regardless of workpiece material
Meaning is different, the function that clamping mechanism can be also servo-actuated with clamp base axle center.
A kind of rotatable hydraulic pressure feeding clip mechanism with self-locking of the present utility model, upper clamp and lower clamp are before clamping cylinder
When entering, a clamping force is produced, when workpiece plate or section bar material outwards produce pulling force, clamp galianconism is produced a grip force,
And as pulling force becomes big, grip force caused by two short axles equally becomes big, and the torque of short axle is less than locking upper arm and locks underarm again
Torque, the clamping force of clamp is more increased, produce the situation for the more drawing the more tight, reach the purpose clamped with self-locking.The folder of clamp
Expect that direction surrounds the axle servo rotary of clamp base, material folding draw angle is not affected.
