Description

Double-disc friction press

Technical Field

The utility model relates to a friction press field specifically is a double plate friction press.

Background

The double-disc friction press is used for die forging, extrusion, bending, straightening and the like, is widely applied to the field of metal product machining, and the patent document with the publication number of CN207509789U and the name of the double-disc friction press discloses a switching method for driving a friction disc to realize the working states of the two friction discs through a cylinder, so that two original driving motors can be reduced to one driving motor, the energy is saved, but the double-disc friction press has the following defects in the practical use process: the stroke and the pressure provided by the cylinder are fixed, if the roundness precision of the flywheel is poor or the precision is poor due to abrasion, the pressure between the flywheel and the friction disc can be periodically changed, the cylinder cannot be automatically adjusted, the cylinder is easy to damage when the pressure is too high, the friction force is insufficient when the pressure is too low, and the equipment cannot normally work.

Disclosure of Invention

The utility model aims at providing a double plate friction press in order to solve the problem that pressure variation between the unable automatic adjustment adaptation flywheel of cylinder of current double plate friction press and the friction disk, provide a double plate friction press.

The utility model has the following concrete scheme: a double-disc friction press comprises a frame, wherein a die mounting seat is arranged at the bottom of the frame, a cross beam is arranged at the top of the frame, two supports extending upwards are arranged at two sides of the cross beam, sliding sleeves are arranged at the tops of the two supports, a driving shaft moving along the sliding sleeves is arranged in the two sliding sleeves, a driving mechanism is arranged at one end of the driving shaft, two friction discs are fixedly arranged between the two supports of the driving shaft, a threaded hole is formed in the middle of the top of the cross beam, a screw rod is arranged in the threaded hole, the top of the screw rod extends out of the cross beam and is fixedly provided with a flywheel, a pressure head is arranged at the bottom of the screw rod, a bearing is arranged at the other end of the driving shaft, a set of connecting rod operating mechanism is arranged on the outer wall of the bearing, the, the connecting rod other end is articulated with the minor face end of L shape connecting rod, and the corner of L shape connecting rod is articulated with the pillar, the long limit end of L shape connecting rod with the action bars top is articulated, and the action bars bottom is articulated to have operating handle, be equipped with in the frame the extension board with the operating handle is middle articulated, the action bars is formed by action bars A and the combination of action bars B, is equipped with the interval between action bars A and the action bars B, and interval department is equipped with the spring.

Swing arm personally submits 15 ~25 contained angles with vertical.

Be equipped with the spout in the frame, the pressure head both sides be equipped with spout complex slider.

The working principle of the utility model is as follows: when the two friction disks work, only one of the two friction disks is in contact with the flywheel, one of the two friction disks drives the flywheel to rotate forwards to enable the pressure head to descend, the other friction disk drives the flywheel to rotate backwards to enable the pressure head to ascend, the connecting rod operating mechanism drives the driving shaft to move transversely to enable the two friction disks to be switched, and the spring between the operating rod A and the operating rod B enables the force transmitted to the driving shaft by the connecting rod operating mechanism to change adaptively along with the pressure between the flywheel and the friction disks.

Compared with the prior art, the utility model has the following advantages: the spring between the operating rod A and the operating rod B enables the force transmitted to the driving shaft by the connecting rod operating mechanism to be adaptively changed along with the pressure between the flywheel and the friction disc, so that the stable operation of the device is better ensured, and meanwhile, the operating mechanism is lower in cost compared with an air cylinder.
