Abstract
The utility model discloses a mechanical lever type powder forming machine with adjustable cam angle, and belongs to the technical field of the powder metallurgy forming equipment. The mechanical lever type powder forming machine mainly comprises a machine casing, an upper sliding column controlling mechanism, a lower sliding column controlling mechanism and a demolding controlling mechanism; wherein the quantity of the lower levers of the lower sliding column controlling mechanism is two, the lower levers are respectively fixed and connected with a lower lever supporting axle, one end of one of the lower levers is articulated with a connecting rod, and the other end of the other low lever is connected with a lower sliding column; the transmission gear is arranged in the machine casing. The lower lever drives the supporting axle to rotate around a bearing seat during the work, and thus the traditional mode that the integral type lower lever rotates around the supporting axle is changed. Under the condition of increasing the power, the pressing force is increased, but the height of the entire equipment cannot be increased greatly, therefore, the space is fully utilized. The transmission gear of the upper sliding column controlling mechanism is arranged in the machine casing, therefore, the height of the entire equipment is also reduced, and the equipment is more compact and reasonable.
Description
Technical field
The utility model relates to a kind of technical field of powder metallurgy former.
Background technology
The press forming of powder metallurgy is meant powder is placed former, by exerting pressure of powder being made it shaping, sheds pressure then, deviates from the arrangement through heat treatment and later process again from former, becomes the workpiece that adheres to specification.It is a kind of fully automatic powder forming machine of the two-way compacting of pure mechanical lever-type without gas, liquid device, can finish all actions such as dress powder, compacting, the demoulding automatically, two-way compacting is meant that upper and lower stamping pressurizes to the powder that is contained in the former simultaneously, and the characteristics of two-way compacting are that the extrudate density that extrudes is even.Power source is with a motor, through the rotation of V-belt drive drive, after cycloidal-pin wheel decelerator and a pair of gear reduction, drives the upper lever swing through power transmission shaft, eccentric wheel, connecting rod, and the upper lever driving is gone up traveller and done upper and lower reciprocating motion, presses in the formation.Pressing down is by being contained in the cam that presses down in power transmission shaft left side, drives down lever through fork, coupling bar and swings, and the traveller formation that pumps presses down under the following lever actuated.The demoulding is by being contained in the demoulding cam on the power transmission shaft, and the goods of compacting being finished through demoulding lever eject from former.The dress powder is meant that the powder feeder of filling powder is advancing under the promotion of powder feeding cam and lever above the former, and the goods that the front end of its powder feeder will be deviate from from former are earlier pushed the place ahead to.Covered whole cavity space after powder feeder arrives above the former, this moment, bottom punch was descending, under the effect of spring, forms certain vacuum and powder is sucked.After bottom punch arrives certain position, the powder feeder backhaul.Upper and lower stamping carried out new one again and took turns compacting under the drive of mechanism this moment, went round and began again, continuously compacting.
The transmission mechanism of traditional powder forming machine generally adopts multi-stage speed-reducing, and the transmission number of teeth generally is arranged in outside the casing, and volume is big.Its flywheel generally is installed on the middling speed axle, because flywheel angular speed is unhappy, so its volume is also bigger.The defective of above prior art causes the forming machine volume big, causes the waste of producing material, and also the large-scale powder forming machined of incompatibility needs.
The utility model content
The purpose of this utility model is that design is a kind ofly saved manufactured materials, saves cost, made full use of the space, the mechanical lever-type powder forming machine of compact conformation, handled easily.
The utility model mainly is made up of casing, last traveller controlling organization, following traveller controlling organization, demoulding controlling organization; The described traveller controlling organization of going up comprises powered drive wheel, decelerator, travelling gear, power transmission shaft, eccentric wheel, connecting rod, upper lever and last traveller; Following traveller controlling organization comprises power transmission shaft, presses down cam, fork, coupling bar, lever, lever back shaft and following traveller down down; It is characterized in that: described lever down is two, fixedlys connected with following lever back shaft respectively, and an end and the coupling bar of a following lever are hinged, and the other end of lever is connected with following traveller under the another; Described travelling gear is arranged in the casing.
The lever back shaft left side one end need be set up a holder under the former monoblock type, and holder also will be installed on the chassis block of inferior surface of machine case.Now change into and reduced left side holder and chassis block after split type.During work, following lever drives back shaft rotates around bearing block, has changed that lever rotates around back shaft under traditional monoblock type.Under the condition that increases power, increase press power, and whole device height can not increase too much, made full use of the space.The travelling gear of last traveller controlling organization is arranged in the casing, also can dwindles the height of whole equipment, make it compacter, reasonable.
In addition, decelerator of the present utility model is the cycloidal-pin wheel decelerator.

Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 presses down the cam drive schematic diagram for the outer left side of casing;
Fig. 3 is a partial structurtes schematic diagram in the casing;
Fig. 4 be among Fig. 3 A-A to view.
The specific embodiment
Shown in Fig. 1,2,3,4, the utility model is made up of casing 1, last traveller controlling organization, following traveller controlling organization, demoulding controlling organization.
Last traveller controlling organization comprises powered drive wheel 15, cycloidal-pin wheel decelerator 14, travelling gear 13, travelling gear 12, power transmission shaft 5, eccentric wheel 4, connecting rod 3, upper lever 2 and last traveller 18.Cycloidal-pin wheel decelerator 14 is supported on the casing 1, the input of cycloidal-pin wheel decelerator 14 is connected powered drive wheel 15 and travelling gear 13 respectively with output, power transmission shaft 5 by bearings on casing 1, travelling gear 12 and travelling gear 13 are arranged in the casing 1, travelling gear 12 and power transmission shaft 5 are connected travelling gear 12 and travelling gear 13 external toothings by key.
Following traveller controlling organization comprises power transmission shaft 5, presses down cam 9, fork 10, coupling bar 11, two following lever 8-1 and 8-2, lever back shaft 16 and following traveller 17 down.Pressing down the outer key that passes on left that cam 9 is arranged in casing 1 is connected on the power transmission shaft 5, fork 10 is supported on the casing 1 by bearing pin, and fork 10 matches with the outline that presses down cam 9, and coupling bar 11 1 ends and fork 10 are hinged, and coupling bar 11 other ends are hinged with following lever 8-1.Following lever back shaft 16 bearings are on casing 1, and following lever 8-2 puts in casing 1, and following lever 8-2 is connected down on the lever back shaft 16 by key.Lever 8-1 under also connecting by key on the following lever back shaft 16, the other end of lever 8-2 is connected with following traveller 17.When belling wheel 9 process forks 10 and coupling bar 11 driving depress lever 8-1 move up and down instantly, also driven depress lever 8-2 simultaneously and swung up and down, thereby driven traveller 17 moving linearlies down.
