Description

Technical Field

[0001] This utility model relates to the field of guiding device technology, and in particular to a take-up guiding device that can effectively reduce the height of the wire bow during pull-up. Background Technology

[0002] In tire manufacturing, traditional bias-ply tires use fibers (such as polyester cord and nylon cord) as the skeleton material, while newer radial tires use steel cord as the skeleton material. Steel cord is made of high-quality high-carbon steel with a brass-plated surface, consisting of fine-gauge steel wire strands or ropes with special properties. It is mainly used as the skeleton material for passenger car tires, light truck tires, heavy-duty truck tires, construction machinery tires, aircraft tires, and other rubber products. Radial tires made with steel cord as the reinforcing material have advantages such as long service life, high speed, puncture resistance, good elasticity, safety and comfort, and fuel efficiency.

[0003] During the production of steel cord, some factories use WS800 I-beam reels for winding, which causes excessive bending of the steel wire and excessive bow height. This can easily lead to wire tangling and losses during subsequent production in the alloy furnace. Utility Model Content

[0004] The purpose of this utility model is to provide a take-up guiding device that can effectively reduce the bow height of the medium-drawn steel wire, thereby reducing the stress on the steel wire, reducing the degree of bending, and reducing the angle between the steel wire and the I-beam reel during take-up, thus effectively reducing the bow height of the medium-drawn steel wire and avoiding the problem of wire twisting in the furnace for coarse-gauge products, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A take-up guide device that can effectively reduce the height of the middle-stretch steel wire bow includes a base plate, a guide cylinder connected to one end of the base plate, a first guide wheel assembly connected above the base plate, and a second guide wheel assembly connected to the bottom of the other end of the base plate; a mold roller assembly is connected to the base plate between the first guide wheel assembly and the guide cylinder, and a base is connected to the bottom of the base plate.

[0014] The beneficial effects of this utility model are: This utility model provides a take-up guiding device that can effectively reduce the bow height of the medium-drawn steel wire. When the steel wire is taken up, the stress on the steel wire is reduced, the degree of bending is reduced, and the angle between the steel wire and the I-beam is reduced, thereby effectively reducing the bow height of the medium-drawn steel wire and avoiding the problem of wire twisting in the furnace for coarse-gauge products.

Detailed Implementation

[0022] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1: As Figures 1-3 As shown, a take-up guide device that can effectively reduce the height of the middle-stretch steel wire bow includes a base plate 1, a guide cylinder 2 connected to one end of the base plate 1, a first guide wheel assembly 3 connected above the base plate 1, and a second guide wheel assembly 4 connected to the bottom of the other end of the base plate 1; a mold roller assembly 5 is connected on the base plate 1 between the first guide wheel assembly 3 and the guide cylinder 2, and a base 6 is connected to the bottom of the base plate 1.

[0024] One end of the base plate 1 is connected to a horizontal plate 201 via a bolt assembly 202. One end of the horizontal plate 201 extends to the outer side of one end of the base plate 1 and is connected to a U-shaped frame 204 via a screw a203.

[0025] The guide cylinder 2 is cylindrical, with a wire hole at the center. The bottom end of the guide cylinder 2 is connected to an ear plate 205, which is hinged to the U-shaped frame 204 by a pin.

[0026] The mold roller assembly 5 includes two vertically arranged rollers 501 with a gap between them for the passage of steel wire. The two rollers 501 are rotatably connected to two roller shafts 502 respectively. The bottom end of the roller shafts 502 is snapped into and fixed to the base plate 1 by a nut a503.

[0027] The first guide wheel assembly 3 includes a first guide wheel 301 and two first supports 302; the two ends of the first support 302 are provided with two oblong holes 303, and two bolts a304 pass through the oblong holes 303 and are threaded to the base plate 1; the center of the first guide wheel 301 is connected to a first bearing with an interference fit, the first wheel shaft is interference fitted to the inner ring of the first bearing, and the two ends of the first wheel shaft are connected to the first support 302 by nuts b305. The outer walls of the first wheel shaft on both sides of the first guide wheel 301 are fitted with first spacers 306.

[0028] The second guide wheel assembly 4 includes a second guide wheel 401 and two second supports 402; one end of the second support 402 is threaded to the base plate 1 by a screw b403; a second bearing is interference-fitted at the center of the second guide wheel 401, the second wheel shaft is interference-fitted to the inner ring of the second bearing, and both ends of the second wheel shaft are connected to the second support 402 by nuts c404; second spacers 405 are sleeved on the outer walls of the second wheel shaft on both sides of the second guide wheel 401.

[0029] The top of the base 6 is connected to two columns 601, which are threaded together with bolts a304. The base 6 is connected to the machine platform of the take-up device by bolts b602.

[0030] Example 2: This example is a further improvement on Example 1. The main improvement is that in Example 1, the outer diameter of the guide wheel was too large, resulting in an excessive bow height, which easily led to wire twisting during subsequent assembly. In this example, the above defects can be avoided. Specifically: The outer diameter of the first guide wheel 301 is 95mm, and the guide wire groove V-shaped groove 307 on the outer circular surface of the first guide wheel 301 has an angle of 60°; the second guide wheel 401 has the same structural dimensions as the first guide wheel 301; in this embodiment, by reducing the outer diameter of the first guide wheel 301, the included angle between the steel wire and the surface of the I-beam wheel is further adjusted and reduced, thereby reducing the bow height of the middle-stretch steel wire and reducing the degree of bending of the steel wire.

[0031] Apart from the above, this embodiment is exactly the same as Embodiment 1, and will not be described again here.

[0032] The specific working principle of this utility model is as follows: During operation, the base 6 of the guiding device is connected to the machine platform of the take-up device via bolt b602. The steel wire passes through the wire hole of the guide cylinder 2, passes between the two rollers 501, and then passes through the first guide wheel 301 and the second guide wheel 401 before being wound onto the I-beam reel. This invention reduces the stress on the steel wire during take-up, reduces the degree of bending, and lowers the angle between the steel wire and the I-beam reel, thereby effectively reducing the bow height of the drawn steel wire and avoiding the problem of wire twisting in the furnace for coarse-gauge products.

[0033] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent transformations or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
