Forge bar sharpening machine for external circle
The utility model belongs to forging Surface of Rod Bar processing equipment field, specifically relates to a kind of Ф 110-Ф 480 sharpening machine for external circles that use when the processing of bar outer surface is cleared up that are applied to forge.
Steel ingot is processed and become after bar by forging, have scar in various degree, crackle, bark pocket, the defect such as folding on the surface of bar, these defects, if do not disposed, just will affect the crudy of following process greatly, very easily cause waste product.And conventionally eliminate these defects, and be to carry out grinding cleaning with handgrip abrasive machine, its main drawback has four.
The one,, labor strength is large.The weight of emery wheel own is just very heavy, and the grinding force of emery wheel is again the certain pressure giving by people, and therefore, the muscle power that workman pays is very large, and labour intensity is large, work is arduous especially.
The 2nd,, grinding quality is poor.Workman uses handgrip wheel grinding, and bar is fixed, and the grinding forming is like this point-like, and local surface configuration tolerance is lack of standardization especially, locally sends out blue phenomenon and often occurs, so cause face crack, occurs that quality problems are a lot.
The 3rd,, grinding scope is little.Because bar can not rotate, compared with large scale rod bar grinding, be all halfway, only has lighter material, people can be all right for the surrounding grinding prizing, but aesthetic property is poor especially, and the grinding value range of reconditioning is only confined to the bar between Φ 110-Φ 210 like this.
The 4th,, inefficiency.Because people's strength is limited, so grinding efficiency is low especially, several days ability milled one root timbers.
Summary of the invention
In order to overcome the defect of above-mentioned forging bar cylindrical reconditioning technology, the utility model provides a kind of forging bar sharpening machine for external circle of using while forging the reconditioning of bar cylindrical.
The technical solution adopted in the utility model: forge the total two parts of bar sharpening machine for external circle main body and form, a part is to place the chassis of processed bar, chassis wheel is equipped with in its below, top is provided with trolley running motor, main shaft rotating motor and swiveling wheel two rows, wherein a row is the driving wheel being driven by main shaft rotating motor, another row is driven pulley, on two skate, can place and carry processed forging bar, during start, trolley running motor drives chassis slowly walking in orbit, complete the axial feed of work piece, main shaft rotating motor drives the swiveling wheel on chassis to rotate, drive processed bar to roll on two row's swiveling wheels, wait for bistrique reconditioning processing.Another part is reconditioning processing main frame, it is comprised of critical pieces such as bistrique base, bistrique rotating shaft, bistrique, grinding head motor and balance cylinders, grinding head motor band rotary bistrique rotation after start, with processed Surface of Rod Bar to be grinding, bistrique can rotate as 120o around bistrique rotating shaft by bindiny mechanism, adjust the grinding position of bistrique, operator can be by adjusting the height of push rod in balance cylinder, adjust the dynamics of bistrique on work piece, complete the radial feed of bistrique and work piece, realize the reconditioning to Surface of Rod Bar.
Accompanying drawing explanation
Accompanying drawing is to forge bar sharpening machine for external circle schematic diagram
As shown in the figure: 1, main shaft rotating motor; 2, orbit; 3, chassis wheel; 4, rotation is rolled; 5, bar to be processed; 6, bistrique; 7, bistrique rotating shaft; 8, bistrique base; 9, grinding head motor; 10, operator; 11, balance cylinder; 12, trolley running is laid a foundation.
The specific embodiment
Case study on implementation of the present utility model: as shown in the figure, by all size bar 5 after forging processing, with crane, sling and be put into two rows rotations and roll on 4, start main shaft rotating motor 1, driven rotary is rolled 4 rotations, because bar 5 and rotation are rolled 4 and are contacted the frictional force producing, bar 5 is rotated counterclockwise, now operator 10 starts to start reconditioning main frame, make grinding head motor 9 drives that bistrique 6 connects by belt start rotation, wait for grinding, at this moment operator 10 utilizes the principle that bistrique 6 can rotate around bistrique rotating shaft 7, operate machine and make bistrique be pressed onto processed bar 5 tops, the mechanism simultaneously moving up and down by adjusting balance cylinder 11 push rods, make bistrique 6 increase or reduce the pressure on processed bar 5, the radial feed dynamics of increase and decrease process, complete the radial feed of process.The axial feed of process, is to rely on trolley running motor 1 to rotate, and drives chassis wheel 3 to rotate on orbit 2, thereby drives chassis slowly to move ahead to realize.
The above is technical characterictic of the present invention, and within not departing from spiritual category of the present invention, that is familiar with that those skilled in the art of this technology does various simple in a disguised form still belongs to protection scope of the present invention with modifying.
