Description

Technical Field

[0001] This utility model relates to the field of auxiliary pressure rollers for wire drawing machines, specifically an improved auxiliary pressure roller for wire drawing machines. Background Technology

[0002] The auxiliary pressure roller of the wire drawing machine is mainly used to support, guide and stabilize the wire. During the wire drawing process, it ensures that the wire moves along the predetermined path, prevents deviation from the wire drawing path and reduces tension fluctuations. The auxiliary pressure roller of the traditional wire drawing machine is made of a single non-metallic material such as nylon rod. Its surface hardness and strength are insufficient, which makes it wear quickly. Frequent replacement of the auxiliary pressure roller will affect the production efficiency and lead to high wire drawing production costs.

[0003] Based on this, an improved auxiliary pressure roller for wire drawing machines is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0004] The purpose of this invention is to provide an improved auxiliary pressure roller for wire drawing machines to solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An improved auxiliary pressure roller for a wire drawing machine includes a base roller and a high-strength outer roller. The high-strength outer roller is disposed outside the base roller and is connected to the base roller by screws. Both the base roller and the high-strength outer roller have mounting holes at their shaft centers for mounting the auxiliary pressure roller.

[0007] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0008] In one alternative embodiment: a boss is provided on the outer right end of the high-strength outer wheel, and multiple radial smooth holes are formed on the boss. The radial smooth holes penetrate the high-strength outer wheel. A radial threaded hole is provided on the base wheel at the position corresponding to the radial smooth holes. A radial hexagonal socket screw passes through the radial smooth holes and is threaded into the radial threaded hole.

[0009] In one alternative: the high-strength outer wheel has multiple axial smooth holes on its left end face, the axial smooth holes penetrate the high-strength outer wheel, the base wheel has axial threaded holes at positions corresponding to the axial smooth holes, an axial internal hexagon screw passes through the axial smooth holes, and the axial internal hexagon screw is threadedly connected to the axial threaded hole.

[0010] In one alternative: the radially smooth surface has a countersunk hole at one end near the outer surface of the boss, and the axially smooth surface has a countersunk hole at one end near the left end face of the high-strength outer wheel.

[0011] In one alternative: eight radially oriented light-facing holes are distributed in a regular octagonal pattern on the boss, and eight axially oriented light-facing holes are distributed in a regular octagonal pattern on the left end face of the high-strength outer casing wheel.

[0012] In one alternative: the mounting hole includes a through hole that passes through the center of the base wheel shaft, the right end of the through hole is provided with a first bearing mounting groove, the left end of the through hole is provided with a second bearing mounting groove, and the left end of the high-strength outer wheel is provided with a third bearing mounting groove corresponding to the position of the second bearing mounting groove.

[0013] In one alternative: the second bearing mounting groove and the third bearing mounting groove have the same diameter.

[0014] In one alternative: the base wheel is made of nylon, the high-strength outer wheel is made of copper alloy, and the outer surface of the high-strength outer wheel is chrome-plated.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention utilizes a high-strength outer wheel made of copper alloy to encase a nylon base wheel. The high-strength outer wheel is chrome-plated. The nylon base wheel has a lower production cost, while the high-strength outer wheel made of copper alloy has high strength. The chrome plating further increases the hardness of the outer surface of the high-strength outer wheel. This approach balances controlling the production cost of the auxiliary pressure roller while extending its service life, thereby reducing the replacement frequency of the auxiliary pressure roller and improving wire drawing production efficiency.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] In one embodiment, such as Figures 1-5 As shown, an improved auxiliary pressure roller for a wire drawing machine includes a base roller 101 and a high-strength outer roller 102. The high-strength outer roller 102 is disposed outside the base roller 101 and is connected to the base roller 101 by screws. Both the base roller 101 and the high-strength outer roller 102 have mounting holes at their axial centers for mounting the auxiliary pressure roller.

[0025] In this embodiment, the base wheel 101 uses inexpensive materials, resulting in low production costs. The high-strength outer wheel 102 protects the base wheel 101 and is in direct contact with the wire. The high-strength outer wheel 102 is not easily worn and has a long service life. The base wheel 101 and the high-strength outer wheel 102 are connected together by screws, which balances controlling the production cost of the auxiliary pressure roller while improving its service life.

[0026] In one embodiment, such as Figure 3As shown, a boss 201 is provided on the outer right side of the high-strength outer wheel 102. Multiple radial smooth holes 202 are formed on the boss 201, penetrating the high-strength outer wheel 102. A radial threaded hole 203 is provided on the base wheel 101 at the position corresponding to the radial smooth holes 202. A radial hexagonal socket screw 206 passes through the radial smooth holes 202 and is threaded into the radial threaded hole 203. Multiple axial smooth holes 204 are provided on the left end face of the high-strength outer wheel 102, penetrating the high-strength outer wheel 102. An axial threaded hole 204 is provided on the base wheel 101 at the position corresponding to the axial smooth holes 204. An axial hexagonal screw 207 is inserted into the axial smooth hole 204 and threaded into the axial threaded hole 205. The axial hexagonal screw 207 is threaded into the axial threaded hole 205. There are eight radial smooth holes 202 distributed in a regular octagon on the boss 201. There are eight axial smooth holes 204 distributed in a regular octagon on the left end face of the high-strength outer wheel 102. The radial hexagonal screw 206 and the axial hexagonal screw 207 cooperate to make the base wheel 101 and the high-strength outer wheel 102 tightly connected. After long-term use, the base wheel 101 and the high-strength outer wheel 102 are not prone to relative rotation, thus ensuring the actual use effect of the auxiliary pressure roller.

[0027] In one embodiment, such as Figure 3 As shown, the radial smooth surface 202 has a cylindrical countersunk hole at one end near the outer surface of the boss 201, and the axial smooth surface 204 has a cylindrical countersunk hole at one end near the left end face of the high-strength outer wheel 102. After the base wheel 101 and the high-strength outer wheel 102 are locked together by the radial hexagon socket screw 206 and the axial hexagon socket screw 207, the heads of the radial hexagon socket screw 206 and the axial hexagon socket screw 207 are both in the cylindrical countersunk hole. When the auxiliary pressure roller rotates, the radial hexagon socket screw 206 and the axial hexagon socket screw 207 are less likely to come into contact with foreign objects.

[0028] In one embodiment, such as Figure 1 and Figure 3 As shown, the mounting hole includes a through hole 301 that passes through the shaft of the base wheel 101. The right end of the through hole 301 is provided with a first bearing mounting groove 302, and the left end of the through hole 301 is provided with a second bearing mounting groove 303. The left end of the high-strength outer wheel 102 is provided with a third bearing mounting groove 304 corresponding to the position of the second bearing mounting groove 303. The second bearing mounting groove 303 and the third bearing mounting groove 304 have the same diameter. When installing the auxiliary pressure roller, a bearing is installed in the first bearing mounting groove 302, and the same bearing is installed in the second bearing mounting groove 303 and the third bearing mounting groove 304. Then, the auxiliary pressure roller is installed on the wheel axle. This reduces the rotational resistance of the auxiliary pressure roller and improves the integrity between the base wheel 101 and the high-strength outer wheel 102, which is beneficial to improving the service life of the auxiliary pressure roller.

[0029] In one embodiment, such as Figure 3 As shown, the base wheel 101 is made of nylon, and the high-strength outer wheel 102 is made of copper alloy. The outer surface of the high-strength outer wheel 102 is chrome-plated. The nylon base wheel 101 has a lower production cost, while the copper alloy high-strength outer wheel 102 has high strength. Furthermore, the chrome plating on the outer surface of the high-strength outer wheel 102 further increases the hardness of its outer surface. Using the high-strength outer wheel 102 as an outer protective layer for the base wheel 101 balances the need to control the production cost of the auxiliary pressure roller while improving its service life.

[0030] The above embodiment discloses an improved auxiliary pressure roller for a wire drawing machine. The base roller 101 is made of nylon, which has a lower production cost. The high-strength outer roller 102, made of copper alloy, has high strength, and its chrome plating further increases the hardness of its outer surface. Using the high-strength outer roller 102 as an outer protective layer for the base roller 101 balances controlling the production cost of the auxiliary pressure roller while improving its service life. The radial hexagonal socket screw 206 and the axial hexagonal socket screw 207 cooperate to... The base wheel 101 and the high-strength outer wheel 102 are tightly connected. After long-term use, the base wheel 101 and the high-strength outer wheel 102 are not prone to relative rotation, which ensures the actual use effect of the auxiliary pressure wheel. After the base wheel 101 and the high-strength outer wheel 102 are locked together by radial hexagonal screws 206 and axial hexagonal screws 207, the heads of the radial hexagonal screws 206 and axial hexagonal screws 207 are both in the cylindrical countersunk hole. When the auxiliary pressure wheel rotates, the radial hexagonal screws 206 and axial hexagonal screws 207 are not prone to hitting foreign objects.

[0031] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
