Abstract

The utility model relates to a traction wheel cooler of a wire drawing machine, which is composed of a traction wheel (1), a wheel base (2), a main shaft (3), etc., wherein the lower end of the main shaft is additionally provided with a rotary joint (4). The rotary joint comprises a water inlet (5) and a water return hole (6). The main shaft and the wheel base are respectively provided with a water inlet (9) of the main shaft, a water return hole (10) of the main shaft, a water return hole (12) of the wheel base, and a water inlet hole (13) of the wheel base. A water inlet pipe (11) in the rotary joint body is projected into the proper position of the upper end of the main shaft. A gap is arranged between the water inlet pipe and a through hole of the main shaft to form into the upper circulation and lower circulation of cooling water. The temperature of the traction wheel and the temperature of a drawing steel wire on the outer diameter are reduced, the working condition and the quality of products are improved.

Description

Wire drawing machine traction wheel cooling device

One, technical field:

The utility model is the cooling device that is used for the key component-traction wheel of water tank drawbench equipment.

Two, background technology:

Wire drawing machine is to utilize wire to produce the plant equipment of principle, realization wire physical size and the characteristic changing of strain and plastic deformation in drawing process, is widely used in the various steel wires of Steel Wire Products Industry, the production of welding wire.

Steel wire will produce a large amount of heats in drawing process, too high temperature will make the ductility of steel wire descend significantly owing to strain-aging, and water tank drawbench traction wheel major part only adopts natural air cooled at present, limited cooling capacity has limited the further raising of drawing speed, thereby has influenced productivity ratio.Therefore it is extremely necessary improving cooling system.

Three, summary of the invention:

For improving wire drawing machine traction wheel cooling situation, the wire drawing machine traction wheel cooling device that the utility model provides is made up of traction wheel, wheel seat, main shaft etc., and set up a swivel joint in the main shaft lower end, this swivel joint comprises water inlet, water return outlet, the alignment of shafts is provided with through hole and counterbore, radially the appropriate location also is provided with inlet opening and backwater hole, and the water inlet pipe in the swivel joint stretches into main shaft upper end correct position from the swivel joint body, between water inlet pipe and the spindle through-hole certain interval is arranged.The wheel seat center line both sides of traction wheel also are respectively equipped with backwater hole, the inlet opening of certain diameter, and its position should make it interface and be communicated with the inner groove of backwater hole, water inlet and traction wheel on the main shaft respectively.

After adopting such structure, the traction wheel of wire drawing machine has increased water cooling again in natural air cooled, make steel wire in the drawing process and with it the temperature rise of the traction wheel of contact be effectively controlled, significantly improve end product quality, boost productivity simultaneously.

Traction wheel structural representation when Fig. 1 is no water-cooling apparatus.

Among the figure: the 1-traction wheel; The 2-wheel seat; The 3-main shaft;

Fig. 2 is the utility model wire drawing machine traction wheel cooling device structural representation.

Among the figure: the 1-traction wheel; The 2-wheel seat; The 3-main shaft; The 4-swivel joint; The 5-water inlet; The 6-water return outlet; The 7-through hole; The 8-counterbore; 9-main shaft inlet opening; 10-main shaft backwater hole; The 11-water inlet pipe; 12-wheel seat backwater hole; 13-wheel seat inlet opening; 14 traction wheel inner grooves

Five, the specific embodiment:

As shown in Figure 2, the utility model is by traction wheel 1, wheel seat 2, main shaft 3 compositions such as grade, and set up a swivel joint 4 in traction wheel main shaft lower end, this swivel joint has water inlet 5, water return outlet 6, and the water source by flexible pipe and work-yard, the outer backwater place of apparatus is communicated with, swivel joint body and main shaft lower end are by being threaded, main shaft axially has additional a long through-hole 7 and counterbore 8, corresponding through hole in upper end and counterbore position radially are provided with main shaft inlet opening 9, main shaft backwater hole 10, water inlet pipe 11 in the swivel joint stretches into the spindle through-hole upper end from the swivel joint body, the mouth of pipe places the counterbore place, spindle through-hole 7 apertures are slightly larger than water inlet pipe 11 external diameters, have the gap between the two.Wheel seat center line both sides, also be respectively equipped with wheel seat backwater hole 12 and wheel seat inlet opening 13, it is radial direction through hole, wherein wheel seat inlet opening center line becomes certain inclination angle with the base, aperture one end and main shaft counterbore connect, cannelure connects in the other end and the traction wheel, the backwater hole and the base of wheel seat center opposite side also have certain inclination angle, its incline direction, angular dimension should be able to make backwater hole one end be communicated with the traction wheel inner groove, radially backwater hole perforation accordingly on the other end and the main shaft, the water that enters swivel joint like this from the water source enters in the main shaft counterbore along water inlet pipe, flow into traction wheel inner groove 14 along the inlet opening, flow at the traction wheel inner chamber, thereby reduce traction wheel temperature rise in the steel wire drawing process, when water inlet reaches a constant volume, the water that has had heat energy enters the backwater hole of wheel seat and main shaft again, along the gap between water inlet pipe and the main shaft, flow into the swivel joint water return outlet, the backwater place that device for transferring is outer, so constantly circulation, can reduce the temperature of drawn steel wire on traction wheel and the external diameter thereof effectively, improve working condition, improve the quality of products.
