Description

A kind of planet tumbling mill

Technical field

The present invention relates to the polishing and the deburring process equipment technology of component of machine, be specially the planet tumbling mill that is used for small shaped mechanical parts grinding and polishing processing, international Patent classificating number intends being Int.C1 ⁷.B24B31/00.

Background technology

The polishing of small-sized machine parts, particularly special-shaped parts and deburring process equipment mainly contain two kinds.A kind of is single roll grinding machine; Another kind is planet tumbling mill (mainly being the horizontal planetary tumbling mill).The single cylinder of single roll grinding machine can only be done simple gyration.When its rotating speed surpassed a critical value, material was subjected to action of centrifugal force will be still in the inwall of this cylinder relatively, thereby can not get grinding.So the grinding rate of single roll grinding machine is very low or say restrictedly, the rotating speed of cylinder generally is controlled at 40-60rpm.Under this operating rate, the milling time of material reaches 10-20 hour, and production efficiency is very low.Single roll grinding machine also has its advantage, is exactly that the operation of loading and unloading material is comparatively convenient.The cylinder of single roll grinding machine is general to incline with ground and puts 45 ° of uses, during the loading and unloading material adopts manual upset mode more, heavy, efficient is low, work is forced the way across greatly, also has potential safety hazard.Single roll grinding machine in industries such as textile equipment, electrical alloy at present still in extensive use.

Horizontal planetary tumbling mill (hereinafter to be referred as tumbling mill) is mainly used in the aftertreatment technology of the production of textile industry rings and renovation technique and knitting eedle.During tumbling mill work, material can produce comparatively violent bump and friction each other under the effect of two dimensional motion, thereby high efficiency, and crudy is good.But except textile industries such as rings, the horizontal planetary tumbling mill that uses can not be accepted extensively by the producer of other industry at present.This mainly be because:

1. improved grinding job requirement difference.Gadgets such as the rings of textile industry and eedle are according to its shape and serviceability requirement, and the material tube of tumbling mill (little barrel) volume ratio is less.This be for fear of between the grinding work-piece because of violent bump makes impaired the deforming in surface, require that its working space is smaller to be designed for good.And some other product, as spinning wire loop, appliance contact, stamping parts etc. should not adopt so little charging basket during grinding, and adopt bigger hexagonal charging basket of volume or circle charging basket.Therefore, the specific (special) requirements of the horizontal planetary tumbling mill incompatibility other industry of using at present, the lapping mode of in other words little barrel does not possess extensive applicability.

2. the loading and unloading material bothers, and labour intensity is big.The horizontal planetary tumbling mill that uses generally is designed to the only little charging basket of 32-60 according to the installation amount requirement at present.The loading and unloading of a large amount of little charging baskets loading and unloading one by one of each little barrel in other words make production process compare with swift or single cylinder production to seem very loaded down with trivial details that duplication of labour amount is big.And the grinder that some other industry is used adopts bigger hexagonal charging basket or circle charging basket, though the quantity of charging basket has reduced, but the weight of material of each charging basket but is multiplied, during the charging basket loading and unloading, same labour intensity is very big, the incompatible actual needs of High-efficient Production in batches.

3. there is potential safety hazard.Measure many, thing loading and unloading material mode heavy and artificial upset and exist bigger production safety hidden danger.

Therefore present tumbling mill can not be promoted the use of more widely, has restricted the raising of specific products quality and stable to a certain extent, does not also meet the modern production requirement of High-efficient Production in enormous quantities.
