Description

Multi-die-cavity feeding mechanism

Technical Field

The utility model relates to a powder forming equipment technical field, concretely relates to multimode chamber feeding mechanism.

Background

In powder metallurgy trade die mould process, especially in small-size part pressing process, for improving work efficiency, can be generally with the mould preparation for many die cavity structures, there are two kinds mould filling metal powder mode: one method is to add excessive metal powder into multiple die cavities simultaneously and scrape off excessive powder by a flat plate after natural filling, and the mode has high efficiency, but because the powder filling density is not uniform, the quality difference of the powder filled in each die cavity is large, and the consistency and the yield of products are influenced. The other method is to adopt a separate weighing method for each die cavity, but in the process of weighing and feeding materials for multiple times, the forming press is always in a waiting state, and the working efficiency is seriously reduced.

Disclosure of Invention

In order to solve the above problems, the utility model provides a many die cavities feeding mechanism.

The utility model provides a technical scheme that its technical problem adopted is: a multi-cavity feed mechanism comprising: the sharp module, set up in installing support on the sharp module, set up in add the feed box on the installing support, its characterized in that: the feeding box is provided with a combined cup, a vibrator, an unloading sliding plate, an air cylinder mounting plate, a rolling bearing, a compression spring and a pressing force adjusting rod, the vibrator is fixed on the side face of the combined cup, the unloading sliding plate is arranged at the bottom of the combined cup and connected with the air cylinder, the air cylinder mounting plate is fixedly connected with a mounting bracket, the rolling bearing is connected with the pressing force adjusting rod through a pin shaft, and the pressing force adjusting rod penetrates through the compression spring and a bottom plate of the combined cup.

Preferably, the combined cup is formed by welding a plurality of conical small cups arranged according to the size of the die and a bracket, and the inner surfaces of the small cups are smooth.

Preferably, the discharging sliding plate is tightly attached to the bottom of the combined cup under the action of a compression spring, and the pre-tightening force of the compression spring is adjustable.

Preferably, the pressing spring applies pressing force to the discharging sliding plate through a rolling bearing.

Preferably, the discharging slide plate is pushed by the air cylinder to discharge and seal.

The utility model has the advantages that:

when the molding press presses products, the weighing equipment weighs the required powder of each die cavity in advance and then adds the corresponding small cup, the molding press does not need to occupy the pressing time of the molding press, when the molding press needs to feed materials, the linear module sends the multi-die-cavity feeding mechanism to the die position of the molding press, and the required powder is added into all the die cavities at one time, so that the feeding time is greatly shortened.

Drawings

The invention will be further described with reference to the following figures and examples:

fig. 1 and 2 are schematic structural diagrams of the present invention.

Detailed Description

Referring to fig. 1 to 2, the present invention provides a multi-cavity feeding mechanism. The method comprises the following steps: the straight line module 1, set up in installing support 2 on the straight line module 1, set up in add feed box 3 on the installing support 2, installing support 2 is fixed in on the slider of straight line module 1, add feed box 3 with the bolt fastening in on the installing support 2. The feeding box 3 is provided with a combined cup 4, a vibrator 5, a compression spring 6, a cylinder mounting plate 7, a cylinder 8, a pressing force adjusting rod 9, a rolling bearing 10 and a discharging sliding plate 11.

The combined cup 4 is formed by welding a plurality of small cups with polished inner surfaces, a bottom plate and a bracket, is fixed on the mounting bracket 2 by bolts and can be replaced according to different mold specifications; the bottom plate of the combined cup 4 is provided with a groove, and the discharging sliding plate 11 is tightly attached to the groove of the bottom plate of the combined cup 4 and slides along the guide of the groove; the discharging sliding plate 11 is connected with the air cylinder 8, is dragged by the air cylinder 8 and is used for controlling the door closing and discharging of the combined cup 4; the air cylinder 8 is fixed on the air cylinder mounting plate 7, and the air cylinder mounting plate 7 is fixedly connected with the mounting bracket 2; guide holes are formed in two sides of the bottom plate of the combined cup 4, the pressing force adjusting rod 9 penetrates through the guide holes, and the pressing spring 6 penetrates through the pressing force adjusting rod 9 and is locked by a nut; the rolling bearing 10 is connected with the pressing force adjusting rod 9 through a pin shaft and supports the discharging sliding plate 11 upwards.

The discharging sliding plate 11 can be abraded in the process of repeated movement, the pressing spring 6 pulls the rolling bearing 10 through the pressing force adjusting rod 9, and the discharging sliding plate 11 is pressed in the groove of the bottom plate of the combined cup 4 all the time, so that powder leakage is prevented.

Furthermore, the utility model discloses install vibrator 5 in combination cup 4 side for prevent that the material from arching, and the unloading accelerates.

The above-mentioned embodiment is only the preferred scheme of the utility model, the utility model discloses there are other embodiments in addition, if will the combination cup changes other shape containers into, perhaps changes the blowing slide into turns over the plate structure. Those skilled in the art can make equivalent changes or substitutions without departing from the spirit of the present invention, and such equivalent changes or substitutions are included in the scope set forth in the claims of the present application.
