Description
Technical Field
The utility model relates to an electric block, concretely relates to are pulley of single-phase miniature electric block.
Background
The electric block, especially the single-phase miniature electric block, is widely applied to various hoisting occasions, and has extremely large market consumption. The single-phase miniature electric block is provided with the pulleys for guiding the steel wire rope, the pulleys for the single-phase miniature electric block are generally of an integral turning structure as shown in fig. 5, the steel materials are large, the price of the steel materials rises in a short time, the price of the product of the miniature electric block cannot be synchronously increased, the profit of the product is seriously compressed, the current situation needs to be changed urgently, and the reduction of the manufacturing cost of the pulleys is proposed to the current urgent agenda.
Disclosure of Invention
The technical problem to be solved in the utility model is to provide a but the at utmost save materials to reduce pulley cost of manufacture's pulley for single-phase miniature electric block.
The utility model discloses a through following technical scheme implement:
the single-phase miniature pulley for electric block has pulley groove, its characterized in that: the pulley is formed by fixedly assembling a pulley body and a bearing arranged in a central hole of the pulley body, the pulley body is provided with a central thin-wall steel plate ring, the outer circumference of the central thin-wall steel plate ring is extruded to form left and right wing plates from two sides in a wheel extrusion mode, and the pulley groove is surrounded by the left and right wing plates to form the shape of the pulley groove.
According to the electric hoist in the technical scheme, the thin-wall steel plate with the thickness equal to that of the central thin-wall steel plate ring is used as the base material of the pulley body of the main pulley component, then the outer circle of the thin-wall steel plate is extruded in a wheel extrusion mode, the outer circle part of the thin-wall steel plate is extruded to form the left wing plate and the right wing plate, the pulley groove shape of the pulley is surrounded by the left wing plate and the right wing plate, and no steel is consumed in the whole machining process of the pulley body. Therefore, the utility model can save the material to the utmost extent to reduce the manufacturing cost of the pulley.
Preferably, the bearing is a needle, ball or roller bearing.
Preferably, the outer ring of the bearing is fixedly pressed with the central hole of the pulley body.
Preferably, the outer ring of the bearing and the central hole of the pulley body are welded and fixed.
Drawings
The utility model discloses there is following figure:
FIG. 1 is a schematic view of the structure of the present invention (the bearing is a needle bearing),
FIG. 2 is a schematic view of the structure of the present invention (the bearing is a ball or roller bearing),
figure 3 is a structural schematic diagram of the pulley body before extrusion molding of the pulley,
figure 4 is a structural schematic diagram of the pulley body after the extrusion molding of the pulley,
fig. 5 is a schematic structural diagram of a pulley for a single-phase miniature electric hoist in the prior art.
Detailed Description
The details and the working principle of the embodiments of the present invention are described in detail below with reference to the accompanying drawings:
as shown in fig. 1 and 2, the utility model discloses a pulley for single-phase miniature electric block has pulley groove 5, and the pulley comprises the pulley body and the fixed equipment of bearing of locating the pulley body centre bore, and the pulley body has central thin wall steel plate circle 1, and the thickness of central thin wall steel plate circle 1 is no longer than 5mm, generally 4mm, and left wing board 3 and right wing board 4 are extruded to both sides through the wheel extrusion mode to the outer circumference of central thin wall steel plate circle 1, pulley groove 5 encloses its shape by left wing board 3, right wing board 4, the bearing is shown in fig. 1 needle bearing 2 or the ball shown in fig. 2, roller bearing 6, adopt crimping or welding mode to fix between the outer lane of bearing and the pulley body centre bore.
The utility model discloses a pulley for single-phase miniature electric block, the preparation of its pulley body at first regards as base material with the thin-walled steel sheet (shown in fig. 3) of the equal thickness of central thin-walled steel sheet circle, then carries out extrusion processing to the excircle of thin-walled steel sheet with wheel extrusion mode, makes its excircle part by about extrusion shaping play pterygoid lamina (shown in fig. 4) to enclose the pulley groove shape of going out the pulley with about the pterygoid lamina, the whole course of working of pulley body does not have the consumption of steel.
