In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides a wear-resisting line wheel of crossing, includes wheel piece, bearing, hole jump ring, clamp bolt, bracing piece, coupling nut etc. the cup joint of wheel piece inner circle and bearing inner race, blocks fixedly with upper and lower jump ring for two holes, clamp bolt adopts the special construction of "cylinder section + screw thread section", and clamp bolt inserts the bearing inner circle, and "cylinder section" and bearing inner circle cup joint the back, the wheel body is twisted the internal thread department of bracing piece one end tip through "screw thread section" of clamp bolt, and the contact surface of bearing inner circle and bracing piece is tight, alright completion whole constitution of crossing the line wheel. The wire passing wheel can be easily installed on the diamond wire production equipment through the external thread part at the tail part of the other end of the supporting rod and the connecting nut.

As the preferred technical scheme, the wheel block is made of quartz glass, and the compression bolt and the support rod are made of stainless steel.

As a preferred technical scheme, the section of the slot of the wheel body adopts a special parabola shape.

Compared with the prior art, the invention has the beneficial effects that:

according to the wear-resistant wire passing wheel provided by the invention, the supporting rod is made of stainless steel, so that the strength and rigidity of the wire passing wheel support are ensured; the wheel block adopts the quartz glass material, the pleasing to the eye easy dismouting of light, more importantly has improved the hardness and the smooth finish on wheel block wire casing surface, frictional force when having reduced the steel wire line, the wire casing adopts special parabola profile line type further to optimize the contact atress distribution when crossing the line, consequently, the difficult local mar or the broken filament that produces of wire casing surface, cross the line steel wire and also be difficult for forming the local scratch defect in surface, the change cycle of crossing the line wheel can prolong greatly, when having guaranteed the finished product line quality, the production efficiency of equipment has also been improved.

In the figure:

1-wheel block; 2-a bearing; 3-snap spring for hole; 4-a hold-down bolt; 5-a support rod; 6-connecting a nut; 7-mounting plate of production equipment.

Detailed Description

The technical scheme of the invention is further explained by combining the attached drawings and the embodiment. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the elements associated with the present invention are shown in the drawings.

As shown in fig. 1, the invention provides a wear-resistant wire passing wheel, which comprises a wheel block 1, a bearing 2, a clamp spring 3 for a hole, a compression bolt 4, a support rod 5, a connecting nut 6 and the like. The inner ring of the wheel block 1 is sleeved with the outer ring of the bearing 2, and the bearing 2 is clamped and fixedly connected in the wheel block 1 by an upper hole and a lower hole through a clamp spring 3; the clamp bolt 4 is the special structure of "cylinder section + screw thread section", and clamp bolt 4 inserts the inner circle of bearing 2, and after "cylinder section" of clamp bolt 4 and the inner circle of bearing 2 cup jointed, the internal thread department of the one end tip of bracing piece 5 is twisted into to wheel body 1 through "screw thread section" of clamp bolt 4, and the contact surface of bearing 2 inner circle and bracing piece 5 is tightly combined, alright completion whole line wheel's constitution. The wire wheel can be easily installed on the mounting plate 7 of the diamond wire production equipment through the external thread part at the tail part of the other end of the supporting rod 5 and the connecting nut 6.

Furthermore, in the existing equipment, the wire passing wheels of the wire releasing end and the wire retracting end generally adopt an integral V-shaped groove steel wheel or a cast iron wheel, the wire passing wheels are heavy in weight and easy to rust, and the steel/iron material is not wear-resistant, so that scratches or broken wires can be generated on the surface of a wire groove of the wire passing wheel after the wire passing wheel is used for a period of time, and partial surface scratches of the surface of the wire can be easily generated when the steel wire passes through the wire groove, thereby affecting the quality and the production efficiency of a diamond wire product. Therefore, in the wear-resistant wire passing wheel provided by the invention, the compression bolt 4 and the support rod 5 are made of stainless steel materials, so that the strength and rigidity of the support of the wire passing wheel are ensured, and rusting is prevented; the wheel block 1 is made of quartz glass, light and attractive, and more importantly, the hardness and the smoothness of the surface of a wire groove of the wheel block can be improved, the friction force of a steel wire during wire passing is reduced, local scratches or broken wires are not easily generated on the surface of the wire groove, the defect of local scratches on the surface of the wire passing steel wire is not easily formed, the replacement period of the wire passing wheel can be greatly prolonged, and the production efficiency of equipment is also improved while the quality of a finished product wire is ensured.

Furthermore, the section of the wire groove of the wheel block 1 is not a simple V-shaped groove structure, but is a special parabola shape, so that the contact stress distribution during wire passing is optimized, and local eccentric wear can be well prevented even if a steel wire is swung or shaken during wire passing.

Furthermore, the interior of the wheel block 1 can be processed into a local hollow structure, and the weight is further reduced under the condition of not influencing the use strength.

It should be noted that, in the wear-resistant wire passing wheel structure, the operation of replacing the wheel body 1 of the wear-resistant part is quite convenient and quick, and the wire passing wheel assembly can be taken down from equipment only by loosening the connecting nut 6; and then the hold-down bolt 4 is unscrewed, and the positioned hole is taken out by the clamp spring 3, so that the wheel body 1 can be replaced.
