Abstract

The utility model relates to a cooling water guiding device of a horizontal-type wire drawing machine, which comprises a movable ring and a static ring. The movable ring is fixed on the end surface of a wire drawing drum wheel of the wire drawing machine, and the contact surface between the movable ring and the wire drawing drum wheel is sealed by a washer; the movable ring is provided with a thin-wall ring part and a thick-wall ring part, wherein, the thin-wall ring part and the inner edge of the wire drawing drum wheel form an annular cavity, and the outer circumferential surface of the thick-wall ring part is provided with at least one annular groove; and the static ring is fixed on immovable parts of the wire drawing machine and is at least provided with one annular plate, and the inner edge of the annular plate is plugged into the annular groove of the movable ring, and a gap is arranged between the inner edge of the annular plate and the bottom of the annular groove. The cooling water guiding device has simple and practical structure, and can effectively prevent the cooling water from wetting the semi-finished product of the steel wire, thereby ensuring the normal work of the wire drawing machine, and improving the wire drawing speed of the horizontal-type wire drawing machine.

Description

A kind of cooling water guide device of horizontal wire drawing machine

Technical field:

A kind of cooling water guide device of wire drawing machine relates in particular to a kind of cooling water guide device of horizontal wire drawing machine, belongs to the servicing unit of wire drawing machine.

Background technology:

In the steel wire drawing process, can produce a large amount of distortion heat and frictional heat, cause steel wire temperature rise meeting to influence the performance of product and the use of equipment,, the process wire that is wrapped in wire drawing drum outer rim is cooled off indirectly so need to take away heat with the inner wall surface of water cooling wire drawing drum.But for common horizontal wire drawing machine, in the cooling procedure, cooling water from the inwall of wire drawing drum along the wheel rim end face toward dirty process, because the infiltration of water diffusion, along with the rotation of wire drawing drum, the external peripheral surface that always has water to cross wheel rim arrives the cylindrical angular region of wire drawing drum, the steel wire surface of semi-finished of twining on it is got wet, thereby destroy following one wire-drawing process with the lubricated condition of work of wire drawing powder, influence product quality, can make the wire drawing machine can not ordinary production in the time of seriously.

Summary of the invention:

The purpose of this utility model is to provide a kind of cooling water guide device of horizontal wire drawing machine, and this device is simple and practical, can prevent effectively that cooling water from traversing across the external peripheral surface of wire drawing drum.

The utility model is that the technical scheme that its purpose of realization is adopted is: a kind of cooling water guide device of horizontal wire drawing machine, comprise rotating ring and stationary ring, and the wire drawing drum end face seal of described rotating ring and wire drawing machine is affixed; At least have a cannelure on the described rotating ring external peripheral surface; Described stationary ring is provided with a ring segment at least, and the inner edge of described each ring segment inserts in the cannelure of rotating ring, and the other end is fixed in frame, and described ring segment quantity is corresponding with cannelure on the rotating ring.

Further improvement of the utility model is: set up described rotating ring separately heavy wall loop section and thin-walled loop section two, the inner circumferential surface of described heavy wall loop section is to wire drawing drum rotor shaft direction projection, described thin-walled loop section is extended to form by inner circumferential surface, and forms an annular chamber with the inner edge of wire drawing drum; Above-mentioned cannelure is located at the heavy wall loop section.

Be provided with seal washer between described rotating ring and the wire drawing drum, and both adopt screw to fix.The preferred 1-3 of the cannelure that has on the described rotating ring.

For recycling water resource, below the end face of rotating ring, be provided with a tank, make cooling water get back to the pond.

The utility model is simple in structure, practical, by the concaveconvex structure of forming by stationary ring and rotating ring, effectively preventing the half-finished formed annular chamber of inner edge by rotating ring and wire drawing drum simultaneously of the sticking wet steel wire of cooling water, can improve cooldown rate and effect, thereby guarantee the horizontal wire drawing machine operate as normal, improve the drawing speed of horizontal wire drawing machine.After adopting said structure, can strengthen cooling water amount.

Description of drawings:

Fig. 1 is the structure diagram that the utility model and wire drawing drum are used.

Among the figure: 1-rotating ring, 1-1-thin-walled loop section, 1-2 heavy wall loop section, 1-3-cannelure, 2-stationary ring, 2-1-ring segment, 3-wire drawing drum, 4-packing ring, 5-steel wire, 6-water inlet pipe, 7-annular chamber, 8-return flume, the rotating shaft of 9-wire drawing drum.

The specific embodiment:

As shown in Figure 1, a kind of cooling water guide device of horizontal wire drawing machine comprises rotating ring 1 and stationary ring 2.Rotating ring 1 is fixed on by screw on the end face of wire drawing drum 3, with 3 rotations of wire drawing drum, packing ring 4 is set on the contact-making surface between the two carries out end face seal; Rotating ring 2 is divided into thin-walled loop section 1-1 and heavy wall loop section 1-2, and the external peripheral surface of heavy wall loop section 1-2 is provided with two cannelure 1-3; Stationary ring 2 has two ring segment 2-1, and the inner edge of each ring segment 2-1 inserts in the corresponding cannelure 1-3, and the axial and radial end face of ring segment 2-1 and cannelure 1-3 all leaves suitable gap.

The course of work is as follows: steel wire 5 is wrapped in the outer rim of wire drawing drum 3, wire drawing drum 3 active rotation, make steel wire 5 by mould by drawing, water pipe 6 sprays cooling water to the inwall of wire drawing drum 3, cooling water is under gravity and action of centrifugal force, flow in the annular chamber 7 that the thin-walled ring 1-1 by the inner edge of wire drawing drum 3 and rotating ring 1 forms along the inwall of wire drawing drum 3, inner surface along rotating ring 1 outwards flows then, when flowing to the end face of rotating ring 1, overwhelming majority water is promptly along end face inflow surface tank 8, because the infiltration of water diffusion, also have part water to flow to the heavy wall ring 1-2 external peripheral surface of rotating ring 1 along the end face of rotating ring 1, when passing through the first road cannelure 1-3 of heavy wall ring 1-2 external peripheral surface, to be intercepted by the ring segment 2-1 in the first road cannelure 1-3 and the groove, 2-1 is dirty along with ring segment, does not almost have water to flow into the second road cannelure 1-3 of rotating ring 1 again.Even there is a spot of water to flow into the second road cannelure 1-3 of rotating ring 1, also can be cut off, and can not arrive the cylindrical angular region of wire drawing drum by the ring segment 2-1 of the second road cannelure 1-3 and Qi Nei, so the steel wire water adhesional wetting that can not be cooled.

Wherein tank 8 communicates with a pond, and the water in the pond can be recycled after heat radiation.
