Description

Technical Field

[0001] This utility model relates to the field of cold working technology of steel pipes, and in particular to an internal oil scraping device for cold rolling of seamless pipes. Background Technology

[0002] The oil scraper is an internal oil scraper installed at the front end of the guide rod. It is made of rubber or nylon and uses a cylindrical object to leave the lubricating oil inside the tube hole during the rolling process, thereby removing the lubricating oil from the tube hole.

[0003] When it is necessary to scrape the oil inside the tube, the traditional scraping method is to install the oil scraping die at the front end of the guide rod. At this time, the guide rod and the oil scraping die are stationary, and the steel tube rotates and advances during the rolling process, thereby scraping the oil on the tube wall. However, during the rotation of the steel tube, the tube wall rubs against the oil scraping die inside the tube, or when used at high temperatures, the oil scraping die may deform or be damaged, thus increasing the number of times the oil scraping die needs to be replaced. Therefore, this solution proposes an internal oil scraping device for cold-rolled tubes to solve the above problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides, for example Figure 1-4 Shown:

[0024] Example 1: Seamless tube cold rolling inner oil scraping device, comprising:

[0025] Oil scraping mold 1;

[0026] High-temperature cloth 2 is sleeved on the outer wall of the oil scraping mold 1. A fixing part is provided at the connection between the oil scraping mold 1 and the high-temperature cloth 2, and a reinforcing part is provided at the connection between the oil scraping mold 1 and the high-temperature cloth 2.

[0027] Mounting component 3 is located on one side of the oil scraping mold 1 and is used to fix the position of the oil scraping mold 1.

[0028] It should be noted that the oil scraping device is a slight modification based on the existing structure of the equipment manufacturer. The oil scraping mold 1 is made of copper, and the high-temperature cloth 2 is made of Kevlar fiber cloth. The copper oil scraping mold 1 and the Kevlar fiber cloth high-temperature cloth 2 are used together. Kevlar fiber cloth has the properties of high temperature resistance and wear resistance, which can effectively enhance the service life during use. At the same time, the copper oil scraping mold 1 also avoids scratching the pipe body and effectively achieves the oil scraping effect. In use, the high-temperature cloth 2 is wrapped around the outer wall of the oil scraping mold 1, and the high-temperature cloth 2 is fixed to the outer wall of the oil scraping mold 1 by the fastener. The connection between the high-temperature cloth 2 and the oil scraping mold 1 is strengthened by the reinforcing component. It is fixed in the required position by the mounting component 3. The inner wall of the pipe body is cleaned by the oil scraping mold 1 and the high-temperature cloth 2 protects the oil scraping mold 1 from damage and replacement.

[0029] Specifically, the reinforcing component includes symmetrically arranged fixing grooves 102 on both sides of the oil scraping mold 1. The high-temperature cloth 2 is inserted and connected inside the fixing groove 102. The fixing groove 102 is fitted with a steel wire 5 for fixing the position of the high-temperature cloth 2. A storage part is provided at the connection between the steel wire 5 and the oil scraping mold 1. The storage part includes a storage groove 103 opened on the inner wall of one side of the fixing groove 102. The steel wire 5 is inserted and connected inside the storage groove 103. Adhesive 4 is provided at the connection between the oil scraping mold 1 and the high-temperature cloth 2. The adhesive 4 is used to fix the position of the high-temperature cloth 2.

[0030] It should be noted that the adhesive 4 is polyurethane adhesive, used to fix the oil scraping mold 1 and the high-temperature cloth 2. Before installing the oil scraping mold 1, the high-temperature cloth 2 is wrapped around the outer diameter twice. During the wrapping process, the high-temperature cloth 2 is fixed with the adhesive 4. Then, the two ends of the high-temperature cloth 2 are fixed with steel wire 5 through the fixing grooves 102 at both ends of the oil scraping mold 1. After fixing, the steel wire 5 is passed through the storage groove 103 on the edge and tied to the two ends of the oil scraping mold 1. Finally, the oil scraping mold 1 is fixed to the front end of the guide rod. During the rolling process, as the tube moves forward, the oil scraping mold 1 will block the oil in the tube and allow it to flow back into the rolling mill. This effectively reduces the difficulty of degreasing in subsequent passes and also effectively prevents lubricating oil from dripping and polluting the production site.

[0031] Example 2: Install component 3, which is applied to the oil scraping device in Example 1;

[0032] Specifically, the mounting component 3 includes a mounting block 301, a limiting rod 303 is fixedly connected to one side of the mounting block 301, a limiting sleeve 302 is fitted on one side of the limiting rod 303, a through hole 101 is opened in the middle of the oil scraping mold 1, the limiting rod 303 is inserted into the inside of the through hole 101, and a blocking block 304 is provided on one side of the oil scraping mold 1, the blocking block 304 is fixedly connected to one end of the limiting rod 303.

[0033] Furthermore, when it is necessary to install the oil scraping mold 1, the installation component 3 is installed at the front end of the cold rolling mill top to guide the tube forward. At this time, a component is installed at the front end of the installation component 3 to fix the inner oil scraping mold 1. The installation steps are as follows: the installation block 301 is installed at the front end of the cold rolling top of the cold rolling mill to guide the tube forward to the guide sleeve. Then, the limiting rod 303 is installed at the front end of the installation block 301 for fixation. The inner oil scraping mold 1 is sleeved on the front end of the limiting rod 303. Finally, the oil scraping mold 1 is squeezed by the blocking block 304. The position of the oil scraping mold 1 is fixed by the blocking block 304 and the limiting sleeve 302.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
