Powder quantitative weighing and die throwing integrated production equipment and work method thereof

Abstract

The invention discloses powder quantitative weighing and die throwing integrated production equipment and a work method thereof. The powder quantitative weighing and die throwing integrated production equipment is composed of feeding mechanisms, storage bins, a charging mechanism, a split charging and weighing mechanism, a conveying mechanism, an unloading mechanism and a controller, all of which are arranged on an equipment frame. Through coordinated cooperation of the multiple feeding mechanisms, the multiple storage bins, the charging mechanism and the split charging and weighing mechanism, all of which are sequentially arranged on the equipment frame, die throwing of two or more kinds of powder raw materials in sequence can be achieved, double-box one-time automatic weighing of each powder can be achieved, and the production efficiency of a pressing machine is improved in a multiplied manner.

Description

technical field [0001] The invention relates to a production line equipment for pressing and molding powder materials, in particular to quantitative weighing and mold casting equipment for powder materials. Background technique [0002] At present, some machine parts and products are pressed from powder on the press, such as automobile brake pads, grinding wheels, polishing pads, etc. In the production process, the powder or metal powder needs to be sub-packaged and put into the mold. Manual sub-packaging is mainly used. The dust at the work site is large, the labor intensity of workers is high, the accuracy of sub-packaging is not high, the production efficiency is low, the yield is low, and the consistency of product quality is difficult to control. In order to solve the above problems, Application No. 201410017116.6 discloses a dual-station auxiliary material automatic dispensing system, which can be used for automatic and precise dispensing of any powdery materials. It...

AI Technical Summary

Problems solved by technology

Although this device solves the problem of accurate and automatic dispensing and conveying of two material boxes at the same time, it cannot be automatically thrown into the mold, and it needs to be manually fed by holding the material box; and its bucket-type lifting feeding device is driven by a motor The sprocket chain realizes the lifting of the hopper. Although it can be automatically lifted and poured into the storage bin, the reason for the inertia of the motor makes it difficult to accurately position the hopper, and the phenomenon of over-position often occurs; although it can be accurately weighed, it requires a pneumatic over-tolerance The error correction device is used to realize the structure, which makes the structure complicated; although the material cup can be transported to the designated position by using the vertical belt conveyor device, it cannot be automatically cast into the mold. High labor intensity and low production efficiency

In addition, at present, some pressing parts need to be fed with different powder materials in batches, and there is no such automatic weighing and feeding equipment at present.
