Abstract

The utility model relates to middle drums of linear type, looping type and pulley type continuous wire drawing machines and drawing cone pulleys of water tank wire-drawing machines, and provides a slip ring type planet rolling drawing wheel, which has counter-pull drawing effect and leads wires and a slip ring to roll and slide on planet wheels freely integrally. When used as a middle drum of a linear type, looping type or pulley type continuous drawing machine, the slip ring type planet rolling drawing wheel can meet the requirement that volume per second of wires drawn by each slip ring type planet rolling middle drum is constant, thereby omitting an automatic speed regulating system of the linear type or looping type wire drawing machine and leading the pulley type continuous wire-drawing machine to have performance and characteristics of the linear type wire drawing machine; and when the slip ring type planet rolling drawing wheel used as the cone pulley of a water tank wire-drawing machine, relative sliding friction among wires and the cone pulley can be avoided, rolling abrasion generated when the wires roll on the planet wheels can also be avoided, and counter-pull drawing effect is generated to convert sliding friction power consumption into rolling friction torque so as to apply work, thereby reducing drawing power consumption further, increasing wire drawing quality further and then avoiding abrasion of the cone pulley.

Description

Sliding ring type planet rolling drawing wheel

Technical field:

The utility model relates to wire fabrication industry wire drawing production equipment, relates in particular to the intermediate winding drum and the water tank drawbench drawing cone pulley of orthoscopic, loop type, pulley-type continuous drawing machine.

Background technology:

At present, the drawing cone pulley of wire fabrication industry water tank drawbench generally all is cast steel (cast iron) wheel body.During the drawing wire rod, all the time exist relative slip between wire rod and cone pulley and produce adhesive wear and abrasive wear thus, thereby cause the cone pulley wearing and tearing to scrap (reprocessing) and the wire surface that frays, destroy the wire rod lubricating layer, increase energy consumption for drawing, reduce grinding tool service life, produce when serious and draw white drawing crack phenomenon, drawing can't be carried out.

In order to improve the sliding mode between wire rod and cone pulley, prolong cone pulley service life, adopt at cast steel cone pulley working surface spraying chromium oxide ceramics or carbide to improve the abrasive resistance of cone pulley both at home and abroad more; The tungsten carbide material of directly selecting for use that has is done cone pulley or hard metal tip is embedded in the tongue-and-groove of cone pulley wheel body to prolong cone pulley service life; Have with wear-resisting steel ring or ceramic wear-resisting ring set on the cone pulley wheel body, and its working surface is made into slight draft to prolong cone pulley service life ...But these methods are not all broken away from the operation principle that wire rod slides at the cone pulley working surface.Therefore, the problem that cone pulley wearing and tearing, wire rod lubricating layer destroy, shorten grinding tool service life, increase energy consumption for drawing is not improved at all.

Orthoscopic, dance wire drawing machine are comparatively advanced in the world at present wire drawing production equipments.Wire rod almost is that straight line carries out from a reel to the another reel, is suitable for very much the continuous drawing of thicker wire (Φ 7-Φ 18), high-tensile steel wires (1200-1300Mpa) and deformed wire.When orthoscopic, dance wire drawing machine drawing wire rod, there is counter pull between the reel of front and back, can significantly reduces energy consumption for drawing, prolong grinding tool service life; Wire rod does not exist rapid bending and axial torsion in drawing process, the end properties of pulling out is better.But the not long-pending line adjusting device of orthoscopic, dance wire drawing machine, it is constant requiring the second volume of every reel in the drawing process, differential surface speed between each reel must and stretching die between lengthening coefficient (A1V1=A2V2 in full accord, A-sectional area, V-speed), otherwise will break, drawing can't be carried out.Therefore, the intermediate winding drum of orthoscopic, dance wire drawing machine must possess the function of automatic speed regulation.In order to reach this requirement, orthoscopic, dance wire drawing machine are equipped with very complicated electric control system and speed adjusting gear, and operation will have suitable technical merit, and maintenance be difficult for to be grasped, and equipment manufacturing cost is higher simultaneously.

That the pulley-type continuous drawing machine has is simple in structure, small investment, easy to operate, advantage such as management is simple.But wire rod is easy to generate axial torsion in drawing process, and the end product quality that influence is pulled out is not suitable for drawing high-tensile steel wires.Because of not possessing the function of counter pull drawing, the unit energy consumption for drawing is higher relatively.

In order to overcome the above problems, 200810048598.6 and 200810196899.3 patents have proposed solution preferably.But in the patent working process planetary gear is had relatively high expectations, and wire rod is slided when moving back on planetary gear, though avoided with cone pulley between relative sliding friction but keep away the rolling wearing and tearing that produced and make the drawing wire rod produce that clocklike continuous axial is little curved of unavoidably on planetary gear, rolling, this may affect to the quality of drawing wire rod.

The utility model content:

At existing issue, the utility model proposes a kind of sliding ring type planet rolling drawing wheel, comprise drawing wheel body, pressure ring, planetary gear, planet wheel spindle, slip ring, anti-friction.Its technical scheme is: the planetary gear that several can freely rotate is installed on the drawing wheel body of sliding ring type planet rolling drawing wheel, a slip ring kink of some slide plate compositions is outside the planetary gear cylindrical, wire rod is wrapped on the slip ring during drawing wire rod, when wire rod need be on sliding ring type planet rolling drawing wheel during sliding moving back, wire rod and slip ring one integrated mass, just slip ring freely rolls on planetary gear.The utility model utilizes planetary gear moment of rolling friction acting, and how much its pulling capacity size is determined by planetary gear moment of rolling friction size and quantity.

Special-effect of the present utility model is, has remarkable counter pull drawing effect in reservation 200810048598.6 and 200810196899.3 patents, reduce wire rod to stretching die pressure, reduce friction power loss, prevent the wire rod scratch, significantly reduce energy consumption for drawing and improve stretching die service life, significantly reduction equipment complexity coefficient and cost and simplify the operation and the basis of safeguarding on, original wire rod is directly slidingly moved back on planetary gear free skating with changing into wire rod and slip ring one integrated mass and moves back rolling on the planetary gear, make between the sliding ring type planet rolling intermediate winding drum or the requirement of drawing wire rod constant volume second between the sliding ring type planet rolling step pulley sheet thereby reach (A1V1=A2V2), particularly make original generation clocklike the little phenomenons curved and that produce the wearing and tearing of rolling of continuous axial no longer produce.Therefore, the utility model further reduces energy consumption for drawing and the quality of drawing wire rod is further enhanced.Simultaneously, the utility model has significantly reduced in the 200810048598.6 and 200810196899.3 patent working processes the requirement of planetary gear, makes more economy and facility of its patent working.In order to prevent that slip ring from producing relative friction with the drawing wheel body, guarantee that slip ring only rolls on planetary gear, the planetary gear profile is designed to step or I-shaped, and its material is through heat treated ferrous material or plastic products.The working surface of slip ring is arc surface or arc surface is made into slight draft that its material is selected the inlet wire intensity decision according to the drawing wire rod for use, can be through heat treated ferrous material, carbide alloy, pottery or plastic products.Wire rod is abrasive puts that to wipe sheet be through heat treated ferrous material, carbide alloy, pottery or plastic products for preventing of installing on the drawing wheel body, can prevent effectively that wire rod from drawing the generation of white drawing crack phenomenon.
