Abstract

The utility model relates to a sectional substrate for a super hard grinding wheel concretely, which belongs to field of sharpeners. The utility model is characterized in that the inner diameter and the outer diameter of the bottom surface of the substrate have inverse angles. Thus, an annular gap is formed on the inner diameter and the outer diameter of the bottom surface of the substrate for containing materials leaked during a material spreading process and a forming process, and thus, the materials can not be stuck on the bottom surface of the substrate, and the problem of the oblique cracks of the a grinding wheel of a grinding steel ball. Simultaneously, a part of the substrate is cut off, and the part can be pressed to expand easily, and thus, the service life of the utility model is greatly extended.

Description

Hard grinding wheel abnormity base plate

The utility model relates to the grinding tool field, specifically is hard grinding wheel abnormity base plate.

The 3150T press is after by technological transformation, because the mould unloading mode of its emery wheel changes mould unloading into one time by twice mould unloading, base plate falls and can reuse, thereby has reduced production cost, has improved production efficiency, thereby is dropped into large-scale production.But find that in use a large amount of oblique segmentation phenomenons appear in the abrasive wheel for abrasion of steel ball of producing.Tracing it to its cause, is that its flowability is fine owing to grind the similar powder-material of steel ball molding mass; can be described as and see that seam just bores, and the tapering of its plug is up-small and down-big that the tapering of modular ring is up big and down small; thereby form a die cavity (as shown in Figure 1) that tapering is arranged; in stand material and pressing process, mill steel ball material enters into the base plate bottom surface from the gap, like this; after suppressing several emery wheels; just glue a layered material in the base plate bottom surface near the external diameter firmly, thereby base plate has been propped, formed certain clearance.When exerting pressure, base plate is pushed back original position again, pressure discharges, and base plate will recover distortion, produces elastic force, just with top emery wheel squeeze crack.Simultaneously, because the 3150T press makes base plate can repeat to fall use, though solved the big problem of base plate occupancy,, through repeatedly repeatedly behind the pressurized, base plate has just been risen by pressure, ejects the same topic that the back base plate does not fall down thereby mould unloading occurs.

The purpose of this utility model is improved base plate for addressing the above problem exactly, is producing distortion in the pressurized process repeatedly to prevent base plate, thereby is guaranteeing the quality of emery wheel, and prolonging the service life of base plate.

The technical solution of the utility model is: on the interior external diameter of base plate bottom surface the angle is arranged.

According to technique scheme, owing on the interior external diameter of base plate bottom surface, the angle is arranged, on the interior external diameter of base plate bottom surface, just form an annular spaces like this, to be contained in the material that spreads out to leak down in material and the forming process, do not cause material to be bonded on the base plate bottom surface, thereby solved the oblique segmentation problem of abrasive wheel for abrasion of steel ball.Simultaneously, owing on the interior external diameter of base plate bottom surface the angle is arranged, has soon cut away at the easiest position of being risen by pressure on the base plate, and greatly improved the service life of base plate than before.Do 50 emery wheels by one class and calculate, base plate of the present utility model can use 10 days 20 classes, improves 20 times service life than before.

Therefore, the hard grinding wheel abnormity back-plane design novelty that the utility model provides, rational in infrastructure, be used for can working continuously with equipment on the 3150T press, to produce and prepare conveniently, production cost reduces greatly; Distortion when having prevented abrasive wheel forming has simultaneously reduced the duplication of labour; And solved emery wheel effectively because of the various crackle aliquation waste products that bottom deformation produces, improved economic benefit.

Describe in detail below in conjunction with the embodiment accompanying drawing.

At first accompanying drawing is described:

Fig. 1 represents the user mode figure of existing base plate;

Fig. 2 represents the user mode figure of base plate of the present utility model.

30 degree angles are arranged on the interior external diameter of base plate 9 bottom surfaces.Base plate 9 is contained on the 3150T press uses, as shown in Figure 2.Among the figure, 1 is the mould unloading knock-pin; 2 is emery wheel; 3 is the mould car; 4 is rotating disk; 5 is pressing plate; 6 is modular ring; 7 is plug; 8 is parallels; 9 is base plate.

Claims

1, a kind of hard grinding wheel abnormity base plate is characterized in that on the interior external diameter of base plate bottom surface the angle being arranged.
