Facilitate gripping by oil cylinder and drive clamp galianconism and locking upper arm and the rotation for locking underarm；The work of hydraulic jack is more put down
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, it is to avoid skid；Pressure sensor can avoid the pressure of upper clamp and lower clamp excessive, cause sheet metal stretching to deform.
In many curved surface formings, a kind of rotatable hydraulic pressure feeding clip mechanism with self-locking is developed so that material folding is pressed from both sides tighter and tighter,
The situation for clamping and skidding being clamped in section bar and sheet metal stretching is thoroughly solved, and is appointed 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 invention, 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, it is ensured that product is in machining accuracy qualification rate up to 98.5%.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
Wherein, 1- upper clamps, 2- lower clamps, 3- plates, 4- locking underarms, 5- clamping cylinders, 6- locking upper arm, 7- joint shafts,
8- clamp galianconism, 9- clamp bases.
Embodiment
The optimal technical scheme that the invention will now be described in detail with reference to the accompanying drawings.
As illustrated, a kind of rotatable hydraulic pressure feeding clip mechanism with self-locking of the present invention, including upper clamp 1 and lower clamp 2,
Upper clamp 1 and lower clamp are oppositely arranged about 2, and plate 3 to be processed is located between upper clamp 1 and lower clamp 2, and upper clamp
1 is arranged on locking upper arm 6, and lower clamp 2 is arranged on locking underarm 4, and joint is passed through in the middle of locking upper arm 6 and locking underarm 4
Axle 7 rotates connection, and the other end of locking upper arm 6 and locking underarm 4 rotates connecting clamp galianconism 8 respectively, two clamp galianconism 8
The other end is rotatably connected on clamp base 9, and tie point and locking upper arm 6 and turn of locking underarm 4 are rotated in clamp base 9
Clamping cylinder 5 is set between dynamic tie point.
Wherein preferred, the other end of locking upper arm 6 and locking underarm 4 is short by the rotation connecting clamp of joint shaft 7 respectively
Arm 8, the other end of two clamp galianconism 8 is 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 invention, whole mechanism is rotatably connected on clamp base,
Can opposed jaws base rotation any angle, in addition the clamping of upper clamp and lower clamp by clamping cylinder drive clamp, and
In the drawing process of plate, upper clamp and lower clamp can press from both sides tighter and tighter, thoroughly solve clamping section bar and sheet metal stretching process
It is middle to clamp situation about skidding.
The setting of joint shaft make it that the rotation of each run-on point is more smooth, and rotate flexible, and joint shaft is provided with
Clamp galianconism and locking upper arm and the rotation for locking underarm are driven beneficial to clamping cylinder；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, it is to avoid skid；Pressure sensor can be with
Avoid the pressure of upper clamp and lower clamp excessive, cause sheet metal stretching to deform.
In many curved surface formings, a kind of rotatable hydraulic pressure feeding clip mechanism with self-locking is developed so that material folding is pressed from both sides tighter and tighter,
The situation for clamping and skidding being clamped in section bar and sheet metal stretching is thoroughly solved, and is appointed 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 invention, upper clamp and lower clamp are advanced in clamping cylinder
When, 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, the grip force that two short axles are produced equally becomes big, and the torque of short axle is less than the power of locking upper arm and locking underarm again
Square, makes the clamping force of clamp more increase, and produces the situation for drawing tighter and tighter, reaches the purpose clamped with self-locking.The material folding of clamp
Direction surrounds the axle servo rotary of clamp base, material folding draw angle is not affected.
A kind of rotatable hydraulic pressure feeding clip mechanism with self-locking of the present invention, 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, it is ensured that product is in machining accuracy qualification rate up to 98.5%.
