Abstract
The utility model discloses a special grinding machine for roller, comprising a machine body, a tail stock, a wheel stock, a head stock, wherein the wheel stock is provided with a wheel electric machine, the head stock is provided with a head stock electric machine, the wheel electric machine is connected with a frequency converter. The frequency converter is a current type frequency converter or a voltage type frequency converter. The structure of the grinding machine is simple, the cost is low, the frequency converter is added only on an electric control box, the roughness of the roller surface of the rolling mill is changed by changing the speed difference of the grinding machine wheel and the head stock electric machine, so as to eliminate the surface aberration of the cold rolling plate.
Description
Technical field
The utility model relates to a kind of grinding machine, and more particularly, it relates to a kind of roll special purpose grinder.
Background technology
In daily life, no matter high-quality cold rolling roll bending is bright plate or inferior tabula rasa, requires the light sensation uniformity, and each position reflecting rate is identical, the aberration that can not exist a variety of causes to produce.In the production process, the aberration reason that cold rolling roll bending produces is varied, for example, the rotation lines that produces during the roller surface grinding, the shadow that the raw material surface stays after because of the different pickling of degree of oxidation, because of existing yield phenomenon, metal material under the tension force effect, produces plastic deformation, the drag line that cold rolling back produces etc.These chromatic aberration defects are fatal defective to thickness and precision and strip shape quality did not influence but require very high tin plate, tame electroplax to have aberration for presentation quality, and the coated layer on surface also is difficult to eliminate the aberration of matrix.Therefore exist this kind defective cold-reduced sheet scope of application to be had a strong impact on.With the roll of different roughness, cold-reduced sheet that can rolling different situations reduces the aberration of cold rolling roll bending.How to go out the roll of surperficial different roughness be iron and steel enterprise's difficult problem all the time in grinding.
The utility model content
The purpose of this utility model is to overcome deficiency of the prior art, provide a kind of simple in structure, cost is low, easily obtain the roll special purpose grinder of the roll of different roughness.
In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposals: comprise lathe bed, tailstock, grinding carriage, the headstock, described grinding carriage is provided with grinding wheel drive mitor, and the described headstock is provided with headstock motor, and described frequency converter is connected with grinding wheel drive mitor.
Described frequency converter is current-mode converter or voltage frequency converter.
The utility model roll special purpose grinder has following beneficial effect compared with prior art:
Simple in structure, cost is low, only sets up frequency converter on electric cabinet, by changing the mode of grinder wheel motor and headstock motor speed difference, changes the roughness of the roller surface of milling train, reaches and eliminates cold rolling roll bending surface chromatic aberration.
Description of drawings
Fig. 1 is a roll special purpose grinder schematic diagram.
The specific embodiment
As shown in the figure, comprise lathe bed 1, tailstock 2, grinding carriage 3, the headstock 4, described grinding carriage is provided with grinding wheel drive mitor 5, and the described headstock is provided with headstock motor 6, and described grinding wheel drive mitor 5 is connected with frequency converter 8, and electric cabinet 7 provides power supply to frequency converter 8.Described frequency converter 8 is current-mode converter or voltage frequency converter.Regulate the grinder wheel motor speeds by frequency converter 8 and change and headstock motor speed difference, can grinding go out the rolling mill roll of different roughness, can eliminate cold rolling roll bending surface chromatic aberration, satisfy the needs of different cold rolling roll bendings with this roll.
Roll grinder grinding wheel drive mitor rotating speed 1450rpm, headstock motor speed 740rpm, grinding wheel drive mitor is adjusted between 740-1450rpm by the frequency converter rotating speed, obtains the different roll of roughness.Select different rolls according to the mechanical property that roll bending is different for use with drafts, come the cold rolling roll bending of corresponding different situations.
The above only is an example of the present utility model, and simultaneously example does not limit the utility model, and is all within spirit of the present utility model and principle, any modification of being done, is equal to replacements, improvement etc., all should be included within practical protection domain.
Claims (2)
1. roll special purpose grinder, comprise lathe bed (1), tailstock (2), grinding carriage (3), the headstock (4), it is characterized in that described grinding carriage (3) is provided with grinding wheel drive mitor (5), the described headstock (4) is provided with headstock motor (6), and described grinding wheel drive mitor (5) is connected with frequency converter (8).
2. roll special purpose grinder according to claim 1 is characterized in that, described frequency converter (8) is current-mode converter or voltage frequency converter.
