Embodiment Construction
[0025] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0026] The specific embodiment of the molding feeding device of concave type emery wheel of the present invention, as figure 2 As shown, it includes a grinding wheel base mounting seat and a feeding auxiliary positioning device. The grinding wheel base mounting base includes a ball turntable 1, a three-jaw chuck 2 arranged on the ball turntable 1, and a mold ring 3 matching the outer circumference of the grinding wheel base 4. Feeding During molding, the three-jaw chuck 2 and the mold ring 3 are clamped and matched to ensure that the rotation of the grinding wheel base is stable when the ball turntable rotates.
[0027] The feeding auxiliary positioning device includes a positioning pressure head 6 and a bracket for fixing the positioning pressure head 6. The positioning pressure head 6 includes a straight section and an inverted cone section connected ...

The invention relates to a forming feed method, preparation method and forming feed device for an inward-sunken-type grinding wheel. The forming feed device for the inward-sunken-type grinding wheel comprises a grinding wheel base body mounting seat and a positioning pressing head, the positioning pressing head is provided with an outward protruding face arranged corresponding to the inward sunkenoblique face of an inward-sunken-type grinding wheel body, and a cavity for forming of a grinding layer of the inward-sunken-type grinding wheel can be formed between the outward protruding face andthe inward sunken oblique face. According to the forming feed device for the inward-sunken-type grinding wheel, through arrangement of the grinding wheel base body mounting seat and the positioning pressing head, a feed space for forming and positioning of the grinding wheel grinding layer is formed between the inward-sunken oblique face and the outward protruding face, even feeding can be ensured, the situation that the thicknesses of the upper portion and the lower portion of the material layer are uneven is avoided, and the forming quality of the inward-sunken-type grinding wheel can be well ensured.
Description
technical field [0001] The invention belongs to the field of grinding wheel manufacture, and in particular relates to a forming and feeding method, preparation method and device for a concave grinding wheel. Background technique [0002] The feeding molding of resin bond superabrasive grinding wheel refers to the use of assembled molds, putting diamond or CBN mixtures in the mold cavity according to the corresponding formula, hot pressing, and then unloading the mold to obtain the grinding wheel of the corresponding shape. Resin bonded superabrasive grinding wheels are generally divided into flat grinding wheels, cup and bowl grinding wheels, and special-shaped grinding wheels. After the mold is assembled, it has a cavity surrounded by a mold ring, a bottom plate, a core, and an indenter. The shape of the cavity space is generally The whole is perpendicular to the bottom plate. When feeding, it can be fed directly, and then scraped with a scraper. This feeding molding proces...
