Problems solved by technology

For small-sized blanks, when the load is applied to grind at the journal position, its own weight is not enough to overcome the overturning force generated by the grinding pressure, and the non-grinding end will warp, which will affect the normal production conduct

Embodiment Construction

[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0035] see figure 1 , figure 2 , a round blank holding device related to the present invention, which includes two bases 1 at the front and rear, both of which are set on the grinding trolley, and two bases 1 are symmetrically arranged on the left and right Guide sleeve 2, said guide sleeve 2 is inserted with a curved arm 3, and each guide sleeve 2 is provided with a reel 4 below, and a steel wire rope 5 is wound on the reel 4, and the lower end of the curved arm 3 is connected to the corresponding The steel wire rope 5 on the reel 4 is connected, and the reel can pull the curved arm downward by winding the steel wire rope, so that the curved arm slides downward in the guide sleeve, and finally the left and right curved arms hold the blank tightly;

[0036] The left and right guide sleeves 2 are arranged at a certain angle, so the curved ar...

Abstract

The invention relates to a circular blank holding device. The circular blank holding device comprises front and rear bases (1); two guide sleeves (2) are symmetrically arranged on the base (1) on theleft and on the right; crank arms (3) are inserted in the guide sleeves (2); a winding drum (4) is arranged under each guide sleeve (2); steel wire ropes (5) are wound on the winding drums (4); and the lower ends of the crank arms (3) are connected with the steel wire ropes (5) on the corresponding winding drums (4). The circular blank holding device can hold and locate a circular blank to preventthe rising phenomenon of the blank in the machining process and cannot affect the self-rotation of the circular blank during milling and the normal grinding operation of a grinding wheel to the blank.

Description

technical field [0001] The invention relates to a circular billet (such as roll) holding device, which is mainly used in the roll manufacturing industry to remove defects such as burrs, scars, ladle sand and other defects and basic allowances on the surface of the original billet in the roll manufacturing industry, and belongs to the technical field of metallurgical machinery. Background technique [0002] The original roll blank is formed by casting, and hard metal sand inclusions will be formed on the surface. The sand inclusions need to be removed before finishing grinding. Usually, the rough turning method is used to remove the sand inclusions. However, because the layer contains molding sand, the turning tool is easily damaged and cannot work. low efficiency. The process of heavy-duty barren grinding is widely used now, and the efficiency can be increased by at least 2 times the original output. [0003] There are many specifications of rolls, and there are correspondi...
