Abstract

A pull-down floating slide rail component of a rotary press is mainly technically characterized in that a base (4) of the pull-down floating slide rail component is equipped with a concave spiral groove, upright walls on both sides of the spiral groove have spiral inner faces and spiral top surfaces, two fixed depression bars (1) are respectively fixed on the top surfaces of the upright walls of the base (4) by screws (5), two floating depression bars (3) in the spiral groove respectively contact with two edges of the upright wall with the spiral face, the floating depression bars (3) and the fixed depression bars (1) are connected by the screws (5) while remaining a certain clearance between the floating depression bars (3) and the fixed depression bars (1), and the screw is penetrated by a spring (2) to be disposed inside the clearance, thereby enabling the floating depression bars (3) to float in the spiral groove of the base (4) of the pull-down floating slide rail up and down.

Description

Pull-down floating slide track component of rotating press

1, technical field

The present invention relates to a kind of improvement of rotary press, be specially adapted to the powder base rotary press that industries such as magnetic industry, medicine company, ceramics are used.

2, background technology

Rotary press is the equipment that is specifically designed to material charging forming, is widely used in industries such as magnetic industry, medicine company, ceramics.A station with the multistation press is an example, and the basic comprising of rotary press comprises: column, fixed axis, upper roller, top rotary table, turntable, lower rotary table, bottom roller, last pressure bar, following pressure bar, drop-down slide rail.The upper, middle and lower rotating disk links together with fixed axis, and with speed, rotation in the same way.Upper and lower roller links to each other with fixed axis, column.On the rotating disk of upper, middle and lower, have coaxial aperture, in the hole of top rotary table, be equipped with can upper and lower slip on pressure bar, last pressure bar top is controlled by upper roller, the lower end of last pressure bar is fixed with punch, in the hole of lower rotary table, be equipped with can upper and lower slip following pressure bar, the upper end of following pressure bar is fixed with lower punch, the lower end of following pressure bar is withstood by bottom roller, in the hole of turntable die is housed, powder is scraped in the die by the material scraper on the turntable.Its basic functional principle is: when upper, middle and lower rotating disk speed together, when rotating in the same way, following pressure bar enters drop-down slide rail, drop-down slide rail has been done fixed groove, and have with the unique fixation clip that is connected as a single entity, fixation clip by drop-down slide rail forces down pressure bar to move downward in groove, and the material powder enters die when pressure bar moves downward down.Behind dress foot-powder material in the die, upper and lower roller drives upper and lower punch simultaneously and does relative motion in die, after treating that powder is pressed into the regulation blank, lower punch continues to move upward, and punch also is forced to return on this moment, blank is ejected from die by lower punch, after blank was forced to eject, following pressure bar continued motion and enters drop-down slide rail once more, and the lower punch that is contained in down on the pressure bar also moves downward, the powder of packing into once more in the die, and continue said process.

In existing rotary press, on, in, during the lower rotary table motion, following pressure bar enters in the drop-down sliding rail groove, because the unique pressing plate of drop-down slide rail is to be connected as a single entity with it, promptly fixing, following pressure bar very likely can not arrive drop-down slide rail bottom, that is to say down that pressure bar becomes suspended state, the lower punch of following pressure bar just can not arrive the charging position of regulation in die, and the material powder is when packing die into, can not guarantee the height of feeding fully, the product weight that suppresses, the uniformity of size is overproof, and the density of product is also loose, thereby has had a strong impact on product quality, reduce product percent of pass virtually, increased cost.

3, summary of the invention

The objective of the invention is to overcome the prior art deficiency, drop-down slide rail is made pull-down floating slide track component.Be equipped with in the pull-down floating slide track component can upper and lower motion unsteady press strip, spring, fixedly press strip, screw.When the unsteady press strip in pressure bar and the drop-down slide track component contacts instantly, under the effect of the press strip upper spring that floats, force and press down rod and move downward, pressure bar is contacted with the pull-down floating slide track component bottom surface fully, the lower punch of following pressure bar just can arrive the height and position of charging in die, the material powder is full of die fully.

Basic ideas of the present invention are: design one cover pull-down floating slide track component, pull-down floating slide track component comprise base, fixedly press strip, unsteady press strip, spring, screw.Have the spill helicla flute on the base, the helicla flute both sides are upright walls of band spiral inner face and spiral end face, the pull-down floating slide track component base is fixed on the rotary press chassis, two fixedly press strip be screwed respectively on the end face of the upright wall of pull-down floating slide track component base, two unsteady press strips contact with the both sides of upright wall band helicoid respectively in helicla flute, and with screw will float press strip and fixedly press strip couple together, leave certain space between these two, and spring is through on the screw, place in the space, can make and float press strip on the helicla flute of pull-down floating slide track component base, float down.Instantly pressure bar in running when unsteady press strip in the pull-down floating slide track component contacts, spring on the unsteady press strip applies certain active force to following pressure bar, force down pressure bar to move downward, and conscientiously contact, thereby guarantee the work loading height of die fully with the inner bottom surface of the base of pull-down floating slide track component.

Advantage described in the present invention is: add pull-down floating slide track component on the chassis, when upper, middle and lower rotating disk speed together, rotation in the same way, pressure bar enters pull-down floating slide track component under in rotation, and moves downward gradually, and the material powder also progresses into die in the process that moves downward.If the pull-down floating slide track component device has been arranged, under the pressure of spring, pull-down floating slide track can be pressed onto following pressure bar with the spiral fluted inner bottom surface of the base of pull-down floating slide track component and contact, and moves on this face.Thereby the lower punch on the following pressure bar can arrive the height and position of charging fully in die.The material powder can be full of die fully, has guaranteed the uniformity of product on weight, size, density that extrudes like this.The use of this cover pull-down floating slide track has simultaneously improved the qualification rate of product, and particularly when compacting E type product, effect is particularly evident.
