Abstract

The utility model relates to a cemented carbide coreless grinding apparatus comprising a grinding wheel, a guide wheel, a pressing plate, a guide plate, a housing, and a connection rod. A work piece is disposed on the guide plate. The pressing plate is disposed on the work piece, and is contacted with an upper surface of the work piece in an extruded manner. The pressing plate is movably connected with connection rod, which is disposed on the housing. One side of the work piece is provided with the grinding wheel, and the other side of the work piece is provided with the guide wheel. An AB connection line exists between a middle shaft A of the work piece and a middle shaft B of the grinding wheel. An AC connection line exists between the middle shaft C of the guide wheel and the middle shaft A of the work piece. The included angle between the AB connection line and the AC connection line is 178degrees. The cemented carbide coreless grinding apparatus has advantages of abilities of preventing the uneven grinding effect of the work piece, reducing the abrasion of the equipment, improving the production efficiency, prolonging the service lifetime of the equipment, and applicability in stab grinding, rib removal, polishing and fine grinding of the work piece.

Description

A kind of carbide alloy centreless grinding device
Technical field
The utility model relates to a kind of carbide alloy centreless grinding device, especially a kind of carbide alloy centreless grinding device that has pressing plate.
Background technology
The carbide alloy main component is tungsten carbide, cobalt and little additive.Polishing or polishing need be passed through in the surface of hard alloy bar, and fine finishining such as follow-up milling just can obtain sintered-carbide tool or hard metal article.
The surface of hard alloy bar needs to use the carbide alloy centreless grinding device that comprises emery wheel, guide wheel, guide plate in polishing or polishing process.
Traditional hard centreless grinding device does not have pressing plate, and workpiece moves ahead under the power of guide wheel drives, and by wheel grinding; Because the skin-friction force of different initial workpiece is different; Be prone to cause the workpiece speed of service deviation to occur, the workpiece of not polishing in workpiece extruding front, back causes workpiece to eject; Thereby cause workpiece polishing effect uneven, the stability that influence is produced.
Workpiece is meant the bar of the carbide alloy that needs polishing or polishing.
Summary of the invention
The purpose of the utility model is in order to overcome the deficiency of prior art, a kind of carbide alloy centreless grinding device that has pressing plate to be provided.
The technical scheme of the utility model is:
A kind of carbide alloy centreless grinding device comprises emery wheel, guide wheel, pressing plate, guide plate, casing and connecting rod, wherein: be placed with workpiece on the guide plate; Pressing plate is arranged at the top of workpiece; And contact with the extruding of the upper surface of workpiece, pressing plate and connecting rod flexible connection, connecting rod is installed on the casing; One side of workpiece is provided with emery wheel, workpiece opposite side be provided with guide wheel; The axis A of workpiece is parallel with the axis B of emery wheel and be in same horizontal plane; The axis A of workpiece and the axis C of guide wheel is parallel to each other and the axis C of guide wheel is positioned under the axis A of workpiece; There is the AB line between the axis A of workpiece and the axis B of emery wheel; Have the AC line between the axis C of guide wheel and the axis A of workpiece, the angle between AB line and the AC line is 178 degree.
Operation principle:
The carbide alloy main component is tungsten carbide, cobalt and little additive.Polishing or polishing need be passed through in the surface of hard alloy bar, and fine finishining such as follow-up milling just can obtain sintered-carbide tool or hard metal article.
The surface of hard alloy bar needs to use the carbide alloy centreless grinding device that comprises emery wheel, guide wheel, guide plate in polishing or polishing process.
Workpiece is meant the bar of the carbide alloy that needs polishing or polishing.
In this device running, workpiece ejects original orbit owing to receive factor such as frictional force originally in the process of moving ahead easily; So this device is provided with pressing plate, workpiece moves under guide wheel power drives, and constantly rubs with emery wheel; The surface of workpiece is at the uniform velocity moved ahead under the suppression of pressing plate by sanding and polishing, has avoided speed occurring because of frictional force is different and has differed; Make workpiece no longer eject original orbit, travelling forward steadily and at the uniform velocity.
The advantage of the utility model is: installed pressing plate additional; The bar of carbide alloy can travel at the uniform speed under guide wheel power drives; Can not eject original orbit, so both avoid the bar polishing effect of carbide alloy uneven, reduce the wearing and tearing of equipment again because frictional force is different; When enhancing productivity, prolonged service life of equipment.
