Abstract
The utility model relates to a paying off disk capable of controlling the tension of a paying off steel wire for heat treatment technology in manufacture equipment for steel curtain wires. The utility model is composed of a stepped main shaft, an I-wheel base, a friction ring and a friction sheet, wherein the stepped main shaft is fixed to a support, and the I-wheel base is connected with the stepped main shaft by a bearing. The friction ring is positioned below the I-wheel base and fixedly connected with the I-wheel base, and the friction sheet is positioned below the friction ring and fixed to a bottom plate of the friction sheet. The friction sheet can be applied to the friction ring under the combined action of a cylinder, a top plate and the bottom plate of the friction sheet. The rotating paying off of an I-wheel positioned on the I-wheel base must overcome the friction between the friction ring and the friction sheet to guarantee the certain tension of the steel wire. The utility model has the key point that the bearing is composed of a planar thrust bearing and a deep groove ball bearing which are respectively arranged on different step surfaces of the stepped main shaft. The paying off disk for heat treatment has the advantages of low cost and high production efficiency, and stable tension can be provided when the I-wheel rotates for paying off.
Description
Technical field:
The utility model relates to a kind of draw drum, especially used heat treatment draw drum in the steel cord manufacturing equipment.
Background technology:
The steel cord is the material requested that rubber tyre is made, and it is formed by the certain structure twisting by many steel wires, and originally every steel wire all is wound on the I-beam wheel that is put in draw drum.The factor that influences steel cord quality is a lot, comprises tensile force, internal stress of structure, twisting technology, each strand steel wire of material property, steel cord etc.Heat treatment draw drum in the prior art, because gauge of wire is thicker, the I-beam wheel weight of coiling is big, this draw drum is made of support, nonstandard bearing, base plate, spindle nose, steel disc, friction plate, wearing piece base plate, top board, cylinder etc. usually, the lower end that to form a upper and lower supporting with nonstandard bearing be the watershed is static, the actinobacillus device that the upper end can rotate, acting in conjunction by cylinder, top board, wearing piece base plate, realize wearing piece and the applying that friction encircles, certain force of strain is provided.In working order down, nonstandard bearing to bear simultaneously from axially and radially alternate load, particularly gravity to the failure by shear of steel ball between the nonstandard bearing, cause the tension force shakiness, the maintenance cost height, and use nonstandard bearing arrangement, procurement cycle is long, and cost height, serious stagnating have been made an appointment with production efficiency.
Summary of the invention:
The utility model provides a kind of tension stability, cost is low, production efficiency is high heat treatment draw drum.
The utility model is achieved by the following technical solution: a kind of heat treatment draw drum, comprise the auspicious main shaft that is fixed on the support down, the I-shaped wheel seat that is connected with main shaft by bearing, be positioned at below the I-shaped wheel seat and the friction ring of fixedlying connected with the I-shaped wheel seat, being positioned at friction ring below and being fixed in wearing piece on the motor sheet base plate, described wearing piece can be at cylinder, the acting in conjunction of top board and wearing piece base plate is fitted down to rub and is encircled, described main shaft is the main shaft of stairstepping, the axle group of described bearing for constituting by a plurality of standard rolling bearings, each bearing of described bearing group is separately positioned on each cascaded surface of main shaft, and is connected with the I-shaped wheel seat.
Described I-shaped wheel seat and main shaft are dismantled the I-shaped wheel seat at the top of main shaft with screw.
Described bearing group comprises a plain thrust bearing that is positioned on the cascaded surface of main shaft top at least.
Described bearing group constitutes good by a plain thrust bearing and two deep groove ball bearings.
Plain thrust bearing and deep groove ball bearing are set on the cascaded surface of the utility model by main shaft substitute nonstandard bearing, realize the rotation unwrapping wire of the relative main shaft of I-shaped wheel seat, changing nonstandard bearing bears simultaneously from alternate load axial and radially, gravity is to the failure by shear of nonstandard bearing steel ball, greatly improve the stability and the production efficiency of tension force, reduced manufacturing and production cost.
Description of drawings:
Fig. 1 is the schematic diagram of the utility model embodiment
Each sequence number is respectively among the figure: 1, support; 2, cylinder; 4, top board; 7, deep groove ball bearing; 8, main shaft; 9, screw; 10, plain thrust bearing; 13, wearing piece base plate; 14, friction ring; 15, wearing piece; 16, I-shaped wheel seat.
The specific embodiment:
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Referring to accompanying drawing, the utility model embodiment comprises that the lower end is fixed in the main shaft 8 on the support 1, the I-shaped wheel seat 16 that is connected with main shaft 8 by plain thrust bearing 10 and two deep groove ball bearings 7 that are arranged on main shaft 8 cascaded surfaces, plain thrust bearing 10 is arranged on the cascaded surface of main shaft top, I-shaped wheel seat 16 is dismantled the I-shaped wheel seat with the top of main shaft 8 with screw 9, be positioned at below the I-shaped wheel seat 16 and the friction ring 14 of fixedlying connected with the I-shaped wheel seat, being positioned at friction ring below and being fixed in wearing piece 15 on the motor sheet base plate 13, wearing piece 15 can be at cylinder 2, the acting in conjunction of top board 4 and wearing piece base plate 13 is fitted down to rub and is encircled 14.
When I-beam wheel on being placed in I-shaped wheel seat 16 is rotated unwrapping wire, must overcome the friction that friction ring 14 and wearing piece 15 relative motions are produced, thereby steel wire can keep certain tensile force when having guaranteed the I-beam wheel unwrapping wire.
