Description

Technical Field

[0001] This utility model relates to the field of steel pipe production technology, and in particular to an outlet dust removal device for a tension reduction machine. Background Technology

[0002] In modern steel pipe production, especially in the production process of CPE units, the requirements for quality control of steel pipes are becoming increasingly stringent. Among them, the precise control of the length of finished pipes is one of the key links to ensure the quality of steel pipes. The WTCA function is an important technical means applied to achieve this goal. This function relies on the precise measurement of the length of raw pipes and finished pipes, and then adjusts the tension of each pipe to make the length of the final produced steel pipes tend to be consistent.

[0003] However, in actual production of small-diameter pipes, a small guide sleeve is used for drilling at the outlet of the tension reduction mill, and a laser length measuring device is used to measure the pipe length at the drilled point. However, as the pipe passes through the guide sleeve at high speed at the outlet of the tension reduction mill, it carries out a large amount of dust, flames, and cooling water from the tension reduction mill frame. These impurities severely interfere with the normal operation of the laser length measuring device, causing the device to mistakenly identify these impurities as pipe body, resulting in a large error in the length measurement of the finished pipe. This error directly affects the effective functioning of WTCA (WT Compensation and Control) and thus reduces the accuracy of steel pipe length control, leading to unstable product quality and difficulty in meeting the market demand for high-precision steel pipes. Therefore, an outlet dust removal device for tension reduction mills is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides an outlet dust removal device for a tension reduction machine, which aims to improve the problem in the prior art where dust, flames, and cooling water carried out by the tube material at high speed through the guide sleeve interfere with the laser length measuring device, causing it to misjudge and resulting in large errors in the length measurement of the finished tube, thus reducing the accuracy of the steel pipe length.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a dust removal device for the outlet of a tension reduction machine, comprising a support frame, a roller rotatably connected to the top of the support frame, the upper surface of the roller contacting the pipe material, and a cleaning mechanism provided on the top of the support frame;

[0008] The reset assembly includes a connecting spring, one end of which is fixedly connected to the inner wall of the limiting plate, and the other end of which is fixedly connected to a reset post. A positioning plate is fixedly connected to the top of the reset post. The outer walls of the positioning plate and the reset post are slidably connected to the inner wall of the limiting plate, and the bottom of the positioning plate is inserted into the top inner wall of the positioning block.

[0009] As a further description of the above technical solution:

[0010] The front part of the support plate has a guide groove, and the inner surface of the guide groove matches the outer wall of the connecting column.

[0011] As a further description of the above technical solution:

[0012] The brush surface of the cleaning plate contacts the outer wall of the pipe, and openings are provided on the upper and lower sides of the pipe.

[0013] As a further description of the above technical solution:

[0022] 1. In this utility model, through the cooperation between the support frame, rollers, tube and its cleaning mechanism, compressed air is discharged from the air blowing plate during the movement of the tube, which can initially blow away a large amount of dust. Then, the outer wall of the tube comes into contact with the brush surface of the cleaning plate to further clean the residual dust, which greatly reduces the impact of dust on the accuracy of subsequent laser length measurement.

In this utility model, through the cooperation between the disassembly components and other structures, when the brush of the cleaning plate is worn or the air blowing plate malfunctions, the disassembly components allow the staff to easily pull out the mounting plate by simply moving the limiting posts to both sides, thus completing the disassembly of the cleaning plate or air blowing plate. This saves maintenance time and labor costs and improves resource utilization efficiency. Attached Figure Description

[0032] 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.

[0033] Reference Figures 1-2 This utility model provides an embodiment of a dust removal device for the outlet of a tension reduction machine, including a support frame 1. A roller 2 is rotatably connected to the top of the support frame 1. The upper surface of the roller 2 contacts the pipe material 3. The rotation of the roller 2 drives the pipe material 3 to move. A cleaning mechanism 4 is provided on the top of the support frame 1. The cleaning mechanism 4 enables the pipe material 3 to be cleaned by dust removal, thereby reducing the impact of dust on the subsequent length measurement accuracy.

[0034] Reference Figures 2-4 The cleaning mechanism 4 includes a support plate 401 fixedly connected to the top of the support frame 1. A movable plate 402 is slidably connected to the inner wall of the support plate 401. Two sets of support plates 401 are provided to support the concave movable plate 402. A connecting column 403 is fixedly connected to the front of the movable plate 402. The connecting column 403 is T-shaped. A fixed plate 410 is fixedly connected to the top inner surface of the movable plate 402. A blowing plate 407 is detachably installed on the fixed plate 410, supporting the blowing plate 407. An air blowing pipe 411 is fixedly connected to the right side of the blowing plate 407, allowing compressed air to be discharged through the blowing plate 407 to clean dust from the pipe 3. A connecting plate 409 is fixedly connected to the left end of the movable plate 402. A cleaning plate 408 is detachably installed at the bottom. The connecting plate 409 is L-shaped to facilitate the connection and fixation of the cleaning plate 408. Both the cleaning plate 408 and the air blowing plate 407 are semi-circular, which improves the cleaning effect. A disassembly component 5 is provided on the top of the cleaning plate 408, which allows the cleaning plate 408 to be disassembled and replaced. A positioning block 405 and a support block 406 are fixedly connected to the front surface of the support plate 401. The support block 406 is located below the positioning block 405. A limit plate 404 is rotatably connected to the inner wall of the support block 406. When the limit plate 404 is rotated to a vertical position, it can limit the movable plate 402. A reset component 412 is provided on the top of the limit plate 404, which can fix and limit the limit plate 404 in the vertical position.

[0035] Reference Figures 3-5The reset assembly 412 includes a connecting spring 4122. One end of the connecting spring 4122 is fixedly connected to the inner wall of the limiting plate 404, and the other end of the connecting spring 4122 is fixedly connected to a reset post 4123. A positioning plate 4121 is fixedly connected to the top of the reset post 4123. The elasticity of the connecting spring 4122 enables the positioning plate 4121 to have the functions of reset and limiting. The outer walls of the positioning plate 4121 and the reset post 4123 are slidably connected to the inner wall of the limiting plate 404. The sliding arrangement avoids movement interference. The bottom of the positioning plate 4121 is inserted into the top inner wall of the positioning block 405. The two are inserted together, as shown in the figure. Figure 4 As shown, at this time, the limiting plate 404 can limit and fix the connecting column 403.

[0036] Reference Figures 3-5 A guide groove is provided at the front of the support plate 401. The inner surface of the guide groove matches the outer wall of the connecting column 403. The guide groove facilitates the connection and fixation of the connecting column 403 and the limiting plate 404. The brush surface of the cleaning plate 408 contacts the outer wall of the tube 3. The contact between the two allows the tube 3 to be cleaned by the brush of the cleaning plate 408 during movement. Openings are provided on the upper and lower sides of the tube 3. The openings help to discharge some dust and moisture before laser length measurement, minimizing measurement errors. A semi-circular groove is provided on the left side of the limiting plate 404. The inner surface of the semi-circular groove matches the outer arc surface of the connecting column 403. The contact between the two allows the connecting column 403 to be limited and fixed. The inner surface of the left side of the positioning block 405 matches the bottom of the limiting plate 404. Figure 4 As shown, a groove is provided on the top of the positioning block 405, and the groove is matched and inserted into the bottom of the limiting plate 404 to prevent the limiting plate 404 from rotating.

[0037] Reference Figure 2 and Figure 6 The disassembly assembly 5 includes a mounting plate 501 fixedly connected to the top of the cleaning plate 408. The outer wall of the mounting plate 501 is inserted into the bottom inner wall of the connecting plate 409. The insertion of the two can achieve the purpose of pre-positioning the mounting plate 501. The bottom inner wall of the connecting plate 409 is elastically connected to a limiting post 503 through a return spring 502. The outer wall of the limiting post 503 is inserted into the inner wall of the mounting plate 501. The elasticity of the return spring 502 enables the limiting post 503 to have the functions of reset and limit. The disassembly assembly 5 is provided in two sets. The other set of disassembly assemblies 5 is located on the top of the air blowing plate 407. The air blowing plate 407 can be quickly installed and disassembled through the setting of the other set of disassembly assemblies 5. The mounting plate 501 is T-shaped. The T-shape setting ensures that the mounting plate 501 will not move downward after positioning. The limiting post 503 has an inclined surface on the side away from the return spring 502. The inclined surface is set to the left. The inclined surface setting facilitates the installation of the mounting plate 501, and the side of the inclined surface facing the mounting plate 501.

[0038] Working principle: At the outlet of the tension reduction machine, the tube 3 is placed on the roller 2. The rotation of the roller 2 drives the tube 3 to move. When dust removal is required on the tube 3, first operate the limiting plate 404 to move the positioning plate 4121 upward. The positioning plate 4121 drives the reset column 4123 to compress the connecting spring 4122, causing the positioning plate 4121 to disengage from the top inner wall of the positioning block 405. At this time, the limiting plate 404 can be rotated so that it no longer limits the connecting column 403. Then, the connecting column 403 pulls the movable plate 402, which slides on the inner wall of the support plate 401. According to the actual situation such as the diameter of the tube 3, adjust the position of the movable plate 402 so that the cleaning plate 408 and the blowing plate 407 can be appropriately close to the tube 3. After adjusting the position, rotate the limiting plate 404 to make it... When the tube is turned to a vertical position, the connecting spring 4122 resets, pushing the positioning plate 4121 to re-insert into the top inner wall of the positioning block 405, fixing the limiting plate 404, and thus limiting and fixing the connecting column 403 and the movable plate 402, ensuring the stability of the cleaning plate 408 and the air blowing plate 407. Then, compressed air enters the air blowing plate 407 through the air blowing pipe 411 and exits from the air blowing plate 407, initially blowing away the dust on the surface of the tube 3, removing some of the dust from the surface of the tube 3. At the same time, the tube 3 moves continuously under the drive of the roller 2. During the movement, the outer wall of the tube 3 contacts the brush surface of the cleaning plate 408, and the brush further cleans the dust remaining on the surface of the tube 3. The two work together to achieve a more thorough dust removal of the tube 3, reducing the impact of dust on the subsequent laser length measurement accuracy.

[0039] During the cleaning process, if the brush of the cleaning plate 408 wears out or the air blowing plate 407 malfunctions and needs to be replaced, the disassembly assembly 5 can be used. For the cleaning plate 408, move the limiting post 503 to both sides. The limiting post 503 overcomes the elastic force of the return spring 502 and detaches from the inner wall of the mounting plate 501. At this time, the mounting plate 501 can be pulled out from the bottom inner wall of the connecting plate 409 to complete the disassembly of the cleaning plate 408. During installation, insert the T-shaped mounting plate 501 into the bottom inner wall of the connecting plate 409. The mounting plate 501 presses against the inclined surface of the limiting post 503, causing the limiting post 503 to compress the return spring 502 and move to the right. When the mounting plate 501 is in place, the limiting post 503 is inserted into the inner wall of the mounting plate 501 under the action of the return spring 502, thus realizing the installation and fixation of the cleaning plate 408. The disassembly and installation of the air blowing plate 407 are similar, and quick replacement can be completed through another set of disassembly assemblies 5 at the top.

[0040] 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.
