Abstract
The utility model discloses an electromagnetic roller used for a separating device before rolling of a galvanized sheet. The electromagnetic roller used for the separating device before rolling of the galvanized sheet comprises a rubber coating stainless steel cylinder and is characterized in that a left shaft head and a right shaft head are arranged at both ends of a stainless steel, a mandrel is arranged in the rubber coating stainless steel cylinder, two ends of the mandrel are respectively inserted into bearing holes of the left shaft head and the right shaft head, the center of the mandrel is a cuboid box without a cover, and an iron is arranged in the cuboid box, and a magnet exciting coil is wound on the periphery of the iron core. Only the stainless steel cylinder rotates while the mandrel is static when the electromagnetic roller used for the separating device before rolling of the galvanized sheet is used, so that an excitation source can directly supply power to a coil, and a slipping ring and a carbon brush are not needed. Meanwhile, polyamine which is attached on the surface of the stainless steel cylinder has an abrasion-resisting performance, so the requirement of a galvanized sheet rolling separating device can be met.
Description
Technical field
The utility model relates to a kind of electromagnetism roller for disengagement gear before the galvanized plate rolling.
Background technology
The existing electromagnetism roller that is used for the front disengagement gear of galvanized plate rolling generally is comprised of six axial iron cores, coil and outer magnetic poles, between six outer magnetic poles by copper bar every magnetic, disengagement gear has two deficiencies before being used for the galvanized plate rolling: owing to being every magnetic by copper bar between six outer magnetic poles of existing electromagnetism roller, the surface just has seam like this, can scratch the galvanized plate surface, directly affect product design; Integral-rotation during simultaneously existing electromagnetism roller work must adopt slip ring and carbon brush to provide excitation source for Electromagnetic wheel, and this has increased the fault rate of equipment.
Summary of the invention
The purpose of this utility model is to provide a kind of can not scratch the galvanized plate surface, the electromagnetism roller that is used for the front disengagement gear of galvanized plate rolling that breakdown of equipment is low.
The technical solution adopted in the utility model is: a kind of electromagnetism roller for disengagement gear before the galvanized plate rolling, include the encapsulate stainless steel cylinder, it is characterized in that: two ends of encapsulate stainless steel cylinder are provided with left and right spindle nose, one mandrel is arranged in the encapsulate stainless steel cylinder, two of mandrel is inserted into respectively left spindle nose and right spindle nose overlaps in the interior bearing hole, is the cuboid box of uncovered in the middle of the mandrel, in-built cored at the cuboid box, the iron core periphery excitation coil of reeling.
Described mandrel two is respectively short mandrel head and long mandrel head, and the periphery of long mandrel head is cylinder, and some is that heart section is useful on wears the through hole that electric wire is used for the square platform of regulating the mandrel angle for its most external.
Described encapsulate stainless steel cylinder is for being surrounded by the non-magnetic stainless steel cylinder of polyurethane adhesive outward.
Described left and right spindle nose is stepped shaft, and the groove of shrinkage pool and dress key is arranged on the large end of left spindle nose, and right spindle nose is empty set, the inner cap of the bearing of interior installation support mandrel and compression bearing.
The utility model only has stainless steel cylinder running in use, and mandrel is static, so excitation source can directly give coil power supply, and does not need slip ring and carbon brush; Encapsulate stainless steel cylinder surface has wear resisting property simultaneously, therefore can satisfy the requirement of galvanized plate rolling disengagement gear.
Description of drawings
Fig. 1 is constructional drawing of the present utility model;
Among the figure: the 1st, left spindle nose, the 2nd, bearing, the 3rd, gland, the 4th, encapsulate stainless steel cylinder, the 5th, mandrel, the 6th, excitation coil, the 7th, iron core, the 8th, gland, the 9th, jam nut, the 10th, right spindle nose cover, the 11st, right spindle nose.
The specific embodiment
The utility model is described in further detail with the specific embodiment with reference to the accompanying drawings for the below:
As can be seen from Figure 1, the utility model includes the encapsulate stainless steel cylinder, is provided with left and right spindle nose at two ends of encapsulate stainless steel cylinder, left and right spindle nose is stepped shaft, the groove of shrinkage pool and dress key is arranged on the large end of left spindle nose, and right spindle nose is empty set, the inner cap of the bearing of interior installation support mandrel and compression bearing.One mandrel is arranged in the encapsulate stainless steel cylinder, and two of mandrel is inserted into respectively left spindle nose and right spindle nose overlaps in the interior bearing hole; Mandrel two is respectively short mandrel head and long mandrel head, and the mandrel centre is the cuboid box of uncovered, and is in-built cored at the cuboid box, the iron core periphery excitation coil of reeling; The periphery of long mandrel head is cylinder, and some is that heart section is useful on wears the through hole that electric wire is used for the square platform of regulating the mandrel angle for its most external.The encapsulate stainless steel cylinder is for being surrounded by the non-magnetic stainless steel cylinder of polyurethane adhesive outward.
Working process:
Install at the electromagnetism roller, before the electromagnetism roller was devoted oneself to work, first rotation mandrel 5 made the driving surface of iron core 7 aim at the zinc coated sheet surface of intending absorption.When rolling is finished in a galvanized plate rolling, when galvanized plate need be converted to another galvanized plate rolling, electromagnetism roller plugged, external force drives the rotation of electromagnetism roller encapsulate stainless steel cylinder inhour by left spindle nose 1, produce enough strong magnetic force after the excitation coil energising and zinc-plated wrench is picked up the track of delivering to another galvanized plate rolling, this galvanized plate rolling begins rolling, and the electromagnetism roller is dead electricity.After rolling is finished in this galvanized plate rolling, when moving to electromagnetism roller below, zinc-plated wrench moves to the track of last galvanized plate rolling because of zinc-plated wrench self gravitation, and last galvanized plate rolling begins rolling.Thereby the galvanized plate rolling is finished in two galvanized plate rolling alternate cycle circulations.
Above demonstration and described groundwork of the present utility model and principal character and advantage of the present utility model; the technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification sheets just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall in claimed the utility model scope, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
