Abstract
The invention provides a jacking mechanism of a powder former, which relates to the technical field of powder forming. The jacking mechanism is arranged on a frame, and comprises a jacking travel adjusting mechanism and a jacking actuating mechanism, wherein the jacking actuating mechanism is controlled by the jacking travel adjusting mechanism, and comprises a main beam and a pressing beam; the main beam is connected with an upper punch; the pressing beam is connected with a die; and the main beam is provided with a jacking head which can move up and down relative to the main beam. After moving downwards to a distance, the lower end of the jacking head is in contact with the upper end of the pressing beam. The main beam is driven by an eccentric wheel to move up and down, wherein the eccentric wheel is arranged under the main beam. A cam which is used for limiting the downward moving distance of the pressing beam is arranged under the pressing beam. A disc spring is sheathed outside the jacking head. The invention adopts the pressing technique of mechanical type die forced floating and bidirectional pressing pull-down type demoulding, adopts double-point force applying to jack and disc spring to extend on the upper part, and has compact and skillful structure.
Description
Technical field
The present invention relates to jacking mechanism of powder former, relate in particular to the powder compacting technical field.
Background technology
General goods only pass through precompressed in the powder compacting process, molded synchronously, but through precompressed, density unevenness was even about pressure often caused goods synchronously, there is top density situation less than normal, cause the low of quality of item, can't satisfy in the industrial production the Products Quality requirement, present for this reason pressing mode adopts three pressuring methods of non-while, increased the roof pressure notion, made that the density of goods is even, quality greatly improves, but its roof pressure mode of present make-up machine adopts bottom single-point roof pressure mostly, adjust from the bottom, structure is looser, is furnished with hydraulic pressure simultaneously, components and parts such as cylinder, structure is comparatively complicated, has increased the maintenance and the maintenance difficulty of make-up machine.
Summary of the invention
The present invention is directed to above-mentioned defective, purpose is to provide that a kind of top-pressure mechanism is simple, the jacking mechanism of powder former of reliable in action.
Technical scheme of the present invention is: be arranged on the frame, comprise roof pressure stroke control mechanism and the roof pressure actuating mechanism of controlling by roof pressure shape journey governor motion, the roof pressure actuating mechanism comprises main beam that is connected with last punch and the compacting crossbeam that is connected with die, main beam is provided with the roof pressure head that main beam relatively moves up and down, when moving downward a segment distance, the bottom of roof pressure head contacts with compacting crossbeam upper end, main beam is moved up and down by the eccentric wheel drive that is provided with in its lower section, be provided with the cam that limits its Bottom Runby below the compacting crossbeam, the roof pressure head is outer sheathed by the dish spring.
Described roof pressure stroke control mechanism comprises drive motors and the transmission mechanism of being made up of series of gears, sprocket wheel, and the output of transmission mechanism is connected with the roof pressure head.
The present invention adopts the mechanical type die to force to float, and two-way compacting pulling-down type demoulding compact technique adopts top two point application of force roof pressure, and the dish spring is flexible, compact conformation, ingenious.

The specific embodiment
This practicality is arranged on the frame 8, comprise roof pressure stroke control mechanism and the roof pressure actuating mechanism of controlling by roof pressure shape journey governor motion, the roof pressure actuating mechanism comprises main beam 5 that is connected with last punch and the compacting crossbeam 16 that is connected with die, main beam 5 is provided with the roof pressure head 14 that main beam 5 relatively moves up and down, when moving downward a segment distance, the bottom of roof pressure head 14 contacts with compacting crossbeam 16 upper ends, main beam 5 is moved up and down by eccentric wheel 18 drives that are provided with in its lower section, be provided with the cam 19 that limits its Bottom Runby below the compacting crossbeam 16, the roof pressure head 14 outer dish springs 13 that are arranged with, described roof pressure stroke control mechanism comprises drive motors and by series of gears, the transmission mechanism that sprocket wheel 20 is formed, the output of transmission mechanism is connected with roof pressure head 14.
Main beam 5 of the present invention is by connecting rod 2, middle base 1 movable being connected on the frame 8, eccentric wheel 18 links to each other with frame 8 with right main shaft 17 by left main shaft 7 with cam 19, the right roof pressure head of the present invention is connected with frame 8 by square axis 10, left side roof pressure head is connected with frame 8 by circle hanging axis 3, left and right sides roof pressure head main beam 5 relatively moves up and down, transmission mechanism is adjusted motor by roof pressure, gear pair 21, sprocket wheel 20 and bevel gear 9 realized and being connected of square axis 10, right gear 12 is realized right roof pressure head overhang by screw thread pair, right gear 12 is connected with left gear 4 by idler gear 11, and left gear 4 is by the control of screw thread pair realization to the overhang of left roof pressure head.
The course of work of the present invention is: the 1) Principles of Regulation of roof pressure stroke control mechanism: rotate roof pressure and adjust C axle 22 through gear pair 21, chain transmission, the moving right gear 12 of bevel gear subband, control the overhang of right roof pressure head through screw thread pair, right gear 12 drives left gear 4 through central gear 11, through screw thread pair can adjusted in concert the overhang of left side roof pressure head, the adjustment amount of roof pressure shape journey of the present invention is 0-6mm; 2) course of action of roof pressure actuating mechanism, the distance that roof pressure head 14 stretches out from main beam 5 is during greater than the height of press strip 15, move downward by control device control main beam 5, left and right sides roof pressure head is at first pressing compacting crossbeam 16 to move downward, when supporting cam wheel on the main shaft of the left and right sides 19 and the support slipper 6 of compacting on the crossbeam contacts and withstand when suppressing crossbeam 16, the end that is synchronized with the movement of last punch and die, but because main beam 5 does not also move to minimum point under the drive of eccentric wheel 18 on the main shaft of the left and right sides, continue to move downward, force dish spring 13 flexible, roof pressure head 14 bounces back relatively, when roof pressure head 14 is withdrawn into main beam 5 bottom surfaces and runs into the press strip 15 of compacting on the crossbeam 16, main beam 5 arrives the compacting summit, and the stroke of roof pressure head 14 withdrawals is the roof pressure stroke.
