Description

Technical Field

[0001] This utility model relates to the field of stainless steel production technology, specifically to a production device for eliminating fine cracks on the surface of stainless steel pipes. Background Technology

[0002] During the production of stainless steel pipes, fine cracks often appear on the surface of the pipes due to various reasons. The current technology for dealing with these fine cracks is to polish the surface of the stainless steel pipe to eliminate them.

[0003] Existing production equipment for eliminating fine cracks on the surface of stainless steel pipes typically adopts an open-air design, which causes fine slag to fly everywhere during polishing, increasing the difficulty of subsequent cleaning. On the other hand, equipment with an outer shell makes it difficult to process the fine slag inside, and the maintenance of the integrated processing chamber requires a shutdown of more than 2 hours, which takes a long time and can easily delay the production schedule.

[0004] Therefore, a solution is needed. Utility Model Content

Detailed Implementation

[0024] 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.

[0025] Please see Figure 1-4 The present invention provides a technical solution to achieve this: including a base 1, a rubber shock-absorbing pad 2, a workbench 3 and a protective mechanism 4. The base 1 is arranged in a front-to-back structure, the rubber shock-absorbing pad 2 is arranged at the bottom of each base 1, the workbench 3 is arranged at the top of the base 1, and the protective mechanism 4 is arranged on the workbench 3.

[0026] The core protective mechanism 4 includes several sliding boxes 41, sliding grooves 42, synchronous motor housings 43, bidirectional lead screws 44, grooves 45, first protective housings 46, second protective housings 47, fixing plates 48, sliders 49, tube grooves 410, limiting mechanisms 411, and polishing mechanisms 412. The sliding boxes 41 are oppositely arranged at the front and rear ends of the worktable 3. Sliding grooves 42 are located inside each sliding box 41. Synchronous motor housings 43 are located at the left end of each sliding box 41. Bidirectional lead screws 44 are located at the right end of each synchronous motor housing 43 and inside the sliding grooves 42. Grooves 45 are... At the top of the workbench 3, the first protective box 46 and the second protective box 47 are arranged in a left-right structure. Fixing plates 48 are located at the front and rear ends of the left side of the first protective box 46 and the front and rear ends of the right side of the second protective box 47. Slider 49 is located at the bottom of each fixing plate 48, biased towards its free end, and on the bidirectional lead screw 44. A tube groove 410 is located at the left end of the first protective box 46 and the right end of the second protective box 47. A limiting mechanism 411 and a polishing mechanism 412 are respectively located inside the first protective box 46 and the second protective box 47. By driving the bidirectional lead screw 44 through the synchronous motor box 43, the first protective box 46 and the second protective box 47 can be opened to both sides, fully exposing the limiting mechanism 411 and the polishing mechanism 412 for easy maintenance and significantly improving maintenance efficiency. Simultaneously, the closed state of the two protective boxes effectively prevents fine debris from splashing when removing fine cracks from the stainless steel tubes inside, facilitating cleaning.

[0027] In detail, the chute 42 has a through-type structure inside the slide box 41, and the groove 45 has an isosceles trapezoidal structure to facilitate the collection of fine debris. The first protective box 46 and the second protective box 47 are both four-sided semi-enclosed structures and are distributed opposite each other. The first protective box 46, the fixing plate 48 and the slider 49 are integrally formed, as are the second protective box 47, the fixing plate 48 and the slider 49. By opening the groove 45 on the worktable 3, the limiting mechanism 411 and the polishing mechanism 412 are independently installed on the groove 45. In conjunction with the protective box, they can guide fine debris to fall into the groove, facilitating subsequent centralized vacuuming and cleaning.

[0028] The limiting mechanism 411 and the polishing mechanism 412 are both located at the top of the groove 45, and the total length of the first protective box 46 and the second protective box 47 is greater than the maximum length from the limiting mechanism 411 to the polishing mechanism 412.

[0029] The side of the first protective box 46 facing the second protective box 47 has a U-shaped structure, and a first sealing strip 461 is provided on the outer half of the U-shaped structure. The side of the second protective box 47 facing the first protective box 46 has a U-shaped structure, and a second sealing strip 471 is provided on the inner half of the U-shaped structure.

[0030] Working principle: During normal operation, a stainless steel tube is inserted through the left slot 410, and after passing through the limiting mechanism 411 and the polishing mechanism 412, it exits through the right slot 410. Fine polishing debris is trapped between the two protective boxes and then falls along the inner wall of the protective boxes onto the groove 45. When vacuuming or maintenance is required, the synchronous motor box 43 can be activated via an external control unit, which rotates the bidirectional lead screw 44. This, in turn, drives the first protective box 46 and the second protective box 47 to move to the left and right respectively via the slider 49 and the fixing plate 48. Once fully open, the interior can be vacuumed or repaired. After completion, the two protective boxes can be closed. The complementary and staggered arrangement between the first sealing strip 461 and the second sealing strip 471 prevents wear between the two protective boxes.

[0031] The components of this utility model are: 1-base; 2-rubber shock-absorbing pad; 3-worktable; 4-protective mechanism; 41-several sliding boxes; 42-sliding groove; 43-synchronous motor box; 44-double-acting lead screw; 45-groove; 46-first protective box; 461-first sealing strip; 47-second protective box; 471-second sealing strip; 48-fixing plate; 49-slider; 410-pipe groove; 411-limiting mechanism; 412-polishing mechanism. These components are all general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. The problem solved by this utility model is that existing production devices for eliminating fine cracks on the surface of stainless steel pipes typically adopt an open-air design, causing fine slag to scatter during polishing, increasing the difficulty of subsequent cleaning. Devices with outer shells struggle to handle the fine slag inside, and maintenance of the integrated processing chamber requires downtime of more than 2 hours, which is time-consuming and easily delays production. This utility model significantly improves maintenance efficiency and facilitates cleaning.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
