Description

Precise forging machine tup adjusts worm screw axial direction buffer structure

Technical field

The present invention relates to precise forging machine technical field, is that precise forging machine tup adjusts worm screw axial direction buffer structure.

Background technology

Precise forging machine while tup drafts is adjusted is also possible to forge workpiece, so, the wink of tup and absorption surface Between, the motion of the part such as pull bar and worm gear in tup adjustment mechanism is stroboscopic motion, and now, input shaft and worm screw turn for continuous It is dynamic.If worm screw axial location is fixed, the motion of worm gear and worm screw will be uncoordinated, so as to due action cannot be completed, and Damage parts.

The content of the invention

It is an object of the invention to provide a kind of precise forging machine tup adjusts worm screw axial direction buffer structure, by making snail using disc spring Bar axial location is changed into travelling, i.e., when worm gear is forced stalling, worm screw being capable of play.

The technical scheme is that precise forging machine tup adjusts worm screw axial direction buffer structure, it at least includes turbine, set, spiral shell Mother, screw rod, worm screw, inner spline housing and power transmission shaft, is characterized in that：In turbine drive part, turbine is led to nut with set conducting, set Cross bearing pin to be fixedly connected, nut is fixed with screw flight, screw rod is hinged with the pull bar in precise forging machine hammer head adjustment device, they are all It is fixedly installed in frame；In turbo-power importation, housing is fixedly connected with frame, and enclosure interior cavity is provided with snail Bar, worm screw drive turbine rotation, and the end of worm screw is external splines, is coordinated with inner spline housing, and power transmission shaft is arranged on the end of housing, Inner spline housing is sleeved on outside power transmission shaft；Worm screw front end is provided with two bearings, and outer ring and the sliding sleeve of two bearings are fixed, sliding sleeve with It is fixed on the axis of guide connection of housing forward end；Guideway is equipped with disc spring, and disc spring both sides are respectively arranged with a pad, and pass through Nut is fixed.

Two described bearings are fixedly connected by nut with sliding sleeve.

Baffle ring is provided between described worm screw front end and sliding sleeve.

It is characteristic of the invention that by making worm screw axial location be changed into travelling using disc spring, as worm screw continuously turns always Dynamic, when tup forges workpiece, and absorption surface moment worm gear stops operating, so as to forcing worm screw axially-movable and compressing disc spring； When tup leaves workpiece, when hindering the power of worm gear wheel to disappear, the compression stress of disc spring release savings promotes worm screw play, and Power transmission shaft drives worm gear wheel together to the rotation of worm screw, and accelerates worm gear wheel, improves tup opening speed.

Embodiment 2

As shown in Fig. 1, precise forging machine tup drafts is carried out by pull bar drive adjusting device in precise forging machine hammer head adjustment device Regulation.

Precise forging machine tup adjust worm screw axial direction buffer structure in, the screw rod 203 in turbine drive part by with pull bar Fixation is hinged, and power source is provided for pull bar.

203 outer sheath of screw rod is equipped with nut 202, and nut 202 is fixed by bearing pin with set 201, and turbine 102 is connected with set 201 Connect, i.e., turbine 102 is rotated and drives set 201 to rotate, so as to pass through the motion that nut 202 is transferred to screw rod 203 and then drives pull bar.

In turbo-power importation, turbine 102 is provided for turbine 102 by worm screw 103 by being turned on worm screw 103 Power.

Worm screw 103 is arranged on the internal cavities of housing 101, and the right-hand member of housing 101 is provided with power transmission shaft 105, power transmission shaft 105 outer sheaths are equipped with inner spline housing 104, and inner spline housing 104 is coordinated with the external splines of 103 right-hand member of worm screw realizes linkage.

The outfan of exterior power source is directly turned on power transmission shaft 105, and then provides power source for worm screw 103.

Two bearings 106 are provided with the left side of worm screw 103, housing 101, and two bearings 106 pass through outer ring and sliding sleeve 107 are screwed, and install baffle ring 111 between worm screw 103 and sliding sleeve 107 additional.

The axis of guide 108 of sliding sleeve 107 and 101 left end of housing is fixed, and the axis of guide 108 guarantees the locality edge of worm screw 103 Axially.

Disc spring 109 is clamped and fastened by nut by two pad 110, is sleeved on outside the axis of guide 108.

During work, power is imported worm screw 103 by power transmission shaft 105 by external power supply, and worm screw 103 drives turbine 102 to move, And then the pull bar of drive screw 203 and connecting screw rod 203, reach the purpose for adjusting tup drafts and forging.

Due to making 103 axial location of worm screw be changed into travelling using disc spring 109, rotate as worm screw 103 is continuous always, work as hammer Head forges workpiece, and absorption surface moment worm gear 102 stops operating, so as to forcing 103 axially-movable of worm screw and compressing disc spring 109；When tup leaves workpiece, when hindering the power that worm gear 102 is rotated to disappear, the compression stress of the release savings of disc spring 109 promotes worm screw 103 plays, and power transmission shaft 105 drives worm gear 102 to rotate to the rotation of worm screw 103 together, and accelerate worm gear 102 to rotate, Improve tup opening speed.

The part and structure that the present embodiment is not described in detail belongs to the well-known components of the industry and common structure or conventional handss Section, is not described here one by one.
