Description
Technical field
The invention belongs to the rolling equipment field, particularly a kind of hydraulic chuck that is used on the rotating bending drawframe.
Background technology
Usually when using stretching-machine stretching metal material, need utilize an end of main folder head-clamp clamping of workpieces usually, the other end of workpiece is fixed on the mould, by being moved by the tight end winding mold tool of main folder head-clamp, makes workpiece produce plastic deformation on mould.Because in process, metal material produces moulding distortion need bear very big pulling force, so workpiece must clip, otherwise the metal material retraction can influence machining accuracy, generally take 4 oil cylinders to promote to go up lower chuck from both direction up and down respectively in the prior art and come clamping work pieces, the main deficiency of its existence is: first, owing to be subjected to the restriction of volume, the chuck profile is unsuitable excessive, thus provide the oil cylinder of power also necessary reduced volume, so the clamping force of chuck will be restricted, in addition, a plurality of oil cylinder actings in conjunction on workpiece, the bad accurate control of its clamping force, also inhomogeneous; The second, workpiece needs to keep clamped condition a period of time when stretching, and need keep the oil pressure of oil cylinder during this section is the maximum of operating pressure always, promptly wastes energy, and easily chuck is caused damage again.
Summary of the invention
The purpose of this invention is to provide a kind of hydraulic clamping head of rotating bending drawframe, it can utilize less power to realize clamped condition and keep.
The technical solution adopted in the present invention is: a kind of hydraulic clamping head of rotating bending drawframe, comprise clamper main body, be fixedly installed on the upper grip on the described clamper main body, be arranged on the lower chuck on the described clamper main body movably, be connected with link rod plate rotationally by first rotating shaft on the described clamper main body, be connected with master rocker rotationally by second rotating shaft on the described link rod plate, one end of described master rocker is connected with described lower chuck by the 3rd rotating shaft, the other end of described master rocker is connected with dynamical element by the 4th rotating shaft, offer gathering sill on the described clamper main body, described the 3rd rotating shaft is inserted in the described gathering sill slidably, described master rocker has a self-locking position, when described master rocker is in this self-locking position, described first rotating shaft, second rotating shaft, the center of the 3rd rotating shaft and the 4th rotating shaft point-blank, described lower chuck pushes against described upper grip.
Say that further the distance at the center of described second rotating shaft is arrived at the center of described the 4th rotating shaft greater than the center of described the 3rd rotating shaft to the distance at the center of described second rotating shaft.
Described upper grip comprises: be fixedly connected on slide plate chair on the described clamper main body, sliding connection at the upper slide on the described slide plate chair, be fixedly connected on the train wheel bridge on the described upper slide; Described lower chuck comprises: lower skateboard on described moving slide plate chair of the moving slide plate chair that is connected with described the 3rd rotating shaft, sliding connection, be fixedly connected on the lower plate on the described lower skateboard, described upper slide and lower skateboard are inclined relative to horizontal setting, and the distance between described slide plate chair and the moving slide plate chair is expansion gradually from front to back.
The front end of described slide plate chair and moving slide plate chair has spring stop respectively, described spring stop, and described clamping plate, between all be equipped with spring.
Be set with oil cylinder on the described clamper main body, be connected with an end of long connecting rod on the piston rod of described oil cylinder rotationally, the other end of described long connecting rod rotates with described master rocker by described the 4th rotating shaft and is connected.
The present invention's advantage compared with prior art is: oil cylinder of whole chuck employing just can be realized the locking to workpiece, and this simplifies the structure greatly, has improved operability and stability; In addition, connection rod set of the present invention can realize self-locking, and in drawing process, the oil cylinder oil pressure is as long as keep a very little pressure just can guarantee that workpiece is clamped, and this has improved the utilization rate of pressure, has saved the energy; Simultaneously pair of slide becomes horn mouth to be obliquely installed also can to form self-locking, increase the reliability of chuck.
