Abstract
The utility model relates to the technical field of precision forging machines, in particular to a precision forging machine hammer adjusting mechanism annular cavity buffering device which at least comprises a pull rod, a screw rod, a sleeve, shells, a sliding sleeve, a guiding shaft and two bearings. The device is characterized in that a first shell, a second shell and a third shell are spliced and fixed on a machine frame, the pull rod is fixed with the screw rod in a hinged mode, and the screw rod is placed in the spliced shell and can move horizontally along an inner cavity of the spliced shell. A nut is placed in the second shell and sleeved outside the screw rod, a key is fixed on the sleeve which is connected with the sliding sleeve through the first bearing and the second bearing arranged at the right end of the sleeve, and the sliding sleeve can move in the third shell along the horizontal direction. The sleeve is further connected with the nut through a pin shaft, and the key is communicated with a worm wheel. The device can effectively lower impact force generated when the rolling reduction of a hammer is too large, and the accident that the hammer can not be opened can be avoided.
Description
Technical field
The utility model relates to the precise forging machine technical field, is precise forging machine tup governor motion annular chamber buffer unit.
Background technology
The precise forging machine rapidity of blow is fast, frequency is high, and tup is done when drafts is adjusted and do not forged, and the impulsive force to pull bar when drafts is excessive is excessive, makes on pull bar screw thread frictional force excessive, and motor can't open it, thereby can't open the accident of tup.
It is impact mitigation measure that existing impact mitigation measure be take the cover be fixed on housing, the motion that rotarily drives pull bar by cover, but carry out large distance while adjusting the tup drafts stopping forging, because the axial location of cover is fixed, frictional force between screw thread is excessive, cause turbine can not drive cover and the rotation of nut, and then screw rod does not move back and forth, thereby can not open tup, cause the accident.
Summary of the invention
The purpose of this utility model is to provide precise forging machine tup governor motion annular chamber buffer unit, can effectively reduce the impulsive force of tup drafts when excessive, the accident of having avoided tup to open.
The technical solution of the utility model is precise forging machine tup governor motion annular chamber buffer unit, which comprises at least pull bar, screw rod, cover, housing, sliding sleeve, the axis of guide and two bearings, it is characterized in that: the first housing, the second housing and the splicing of the 3rd housing are fixing, and be fixed on frame, pull bar and screw rod are hinged fixing, and screw rod is placed in the housing of splicing and moves horizontally along its inner chamber; Nut is placed in the second housing and is enclosed within the screw rod outside, and key is fixed on and puts, and the clutch shaft bearing that cover arranges by right-hand member is connected with sliding sleeve with the second bearing, slides over along continuous straight runs in the 3rd housing and moves; Cover also is connected with nut by bearing pin, key and turbine conducting.
Be full of pressure oil in annular chamber between described sliding sleeve and the 3rd housing.
Be provided with the axis of guide on described the 3rd housing, sliding sleeve is fixedly connected with the axis of guide.
Be provided with turbine and cover in described the second housing.
Characteristics of the present utility model are to be connected with the cover bearing of nut by sliding sleeve, sliding sleeve can slide at housing inner chamber along continuous straight runs, and then drive cover and nut moves axially on the rotation centerline of turbine, and avoided forging power turbine has been produced to axial force, make screw rod and the pull bar can proper motion.
