Description

Technical Field

[0001] The invention relates to the field of splash prevention for all bending types and bent pipe types, in particular to an anti-splash block. Background Art

[0002] When laser cutting tube products with multiple bends or large bend angles, anti-splash blocks need to be inserted into the tube to prevent the splashes from the laser cutting from sticking to the inner wall of the tube and being unable to be directly cleaned or wiped off, thus affecting the product quality. In order to prevent splashes, a set of one-way curved anti-splash blocks are generally inserted into the tube, that is, pins or rivets are inserted into each joint block to connect and assemble into something like a chain, but the anti-splash effect is limited and cannot meet the needs of tube products with multiple bends or large bend angles.

[0003] The prior art provides a slag blocking mechanism that can be adjusted according to the bending situation, which has a wide range of applications. For example, the patent publication number is CN115121975A, which is a chain slag blocking mechanism for blocking cutting slag, including at least two blocking blocks, and the two ends of the blocking block are respectively provided with connecting rods, and the connecting rods of adjacent blocking blocks are hingedly connected. The present invention connects a plurality of blocking blocks in series through hinged connecting rods. When cutting pipe fittings, the blocking blocks are inserted into the pipe fittings, and the blocking blocks are used on both sides of the cutting position to block the splashing metal residues, so as to prevent the slag from adhering to the inner wall of the pipe fittings. However, whether it is to design and manufacture a multi-faceted rotating splash block or a single-faceted angle rotating splash block, it is necessary to manufacture N small joint blocks and N-1 intermediate connecting blocks, which are assembled by pins or rivets to achieve the purpose of rotation. However, the manufacturing cost of a small block is 300-500 yuan, and the manufacturing cost of a multi-faceted rotating splash block will be higher, and the production cycle will be longer. Moreover, the processing and manufacturing cost of a group of splash blocks will be about 10,000 yuan. The more joint blocks are required, the more costs will be.

[0004] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art known to a person skilled in the art. Summary of the invention

[0005] The technical problem to be solved by the present invention is: how to solve the problem that the current anti-splash block is assembled from N small joint blocks and N-1 intermediate connecting blocks, and the manufacturing process is complicated and the cycle is long.

[0006] The present invention solves the above technical problems through the following technical means:

[0007] An integrated anti-splash block capable of rotating in multiple directions and at multiple angles comprises a plurality of joint blocks capable of being rotatably connected in sequence, wherein the rotation axes of adjacent joint blocks are perpendicular to each other, and the joint blocks are in a tubular structure as a whole;

[0008] One end of the joint block includes a rotating circular plate and a rotating convex strip extending along the axial direction of the joint block, and the other end of the joint block includes a rotating circular groove and a rotating groove opened along the axial direction of the joint block; the rotating circular plate is located in the rotating circular groove, and the central angle corresponding to the part of the rotating circular plate located in the rotating circular groove exceeds 180°; the rotating convex strip is inserted into the rotating groove.

[0009] The anti-splash block of the present invention has a rotating circular plate that can rotate axially in a rotating circular groove. During the rotation, the rotating convex strip and the rotating groove also rotate in the same direction. The intersection between the rotating convex strip and the rotating groove can prevent the joint blocks from falling off. The central angle of the part of the rotating circular plate located in the rotating circular groove exceeds 180° to prevent the rotating circular plate from falling off from the rotating circular groove. The rotating axes of adjacent joint blocks are perpendicular to each other, which can realize multi-angle and multi-directional bending of the anti-splash block. There is no need to connect the joint blocks in series with pins or rivets. After cutting directly with a laser cutting machine, an integrated multi-directional rotatable anti-splash block can be obtained. No assembly is required and it can be formed in one piece, thereby reducing production cost and time.

[0010] Preferably, the cross-section of the joint block is square, and a rotating circular plate is symmetrically arranged on two sides of one end of the joint block, and a rotating convex strip is symmetrically arranged on the other two sides, and a rotating circular groove is symmetrically arranged on two sides of the other end of the joint block, and a rotating concave groove is symmetrically arranged on the other two sides; the rotating circular plate and the rotating concave groove are located on the same side, and the rotating convex strip and the rotating circular groove are located on the same side.

[0011] Preferably, the gap between the rotating circular plate and the rotating circular groove is greater than or equal to 0.1 mm.

[0012] Preferably, the gap between the rotating convex strip and the rotating circular groove is 5%-70% of the wall thickness of the joint block.

[0013] Preferably, there are a plurality of avoidance spaces between adjacent joint blocks.

[0014] The avoidance space is used to avoid the rotation of adjacent joint blocks and achieve a larger rotation angle.

[0015] Preferably, there are at least two rotating ridges and rotating grooves.

[0016] Preferably, both sides of the opening end of the rotating circular groove are chamfered.

[0017] Reduce interference after rotation.

[0018] The present invention also discloses a method for manufacturing an integrated anti-splash block that can rotate on multiple sides and at multiple angles, which is characterized in that the integrated anti-splash block that can rotate on multiple sides and at multiple angles is obtained by laser cutting a tube component.

[0019] The present invention can quickly shorten the production cycle of the anti-splash block. Generally, the cutting can be completed in about ten minutes, which is at least two or three days compared with the previous processing cycle. Since the more joint blocks are required, the longer the cycle, the anti-splash block of the present invention can be produced quickly, and the production cycle is not greatly affected by the number of joint blocks.

[0020] Preferably, a tube component with a wall thickness exceeding 2 mm is selected, the tube component is clamped in a laser cutting machine, a cutting program is compiled, and the shape is designed by laser cutting.

[0021] Preferably, after the pipe original is clamped in the laser cutting machine, an iron rod is inserted into the pipe original to prevent the joint block from swinging greatly after cutting;

[0022] During the laser cutting process, area cutting is performed and adjacent areas are separated by pipes.

[0023] On the one hand, the area cutting meets the programming needs of the laser cutting machine itself, and on the other hand, it is convenient for blanking. Therefore, adjacent areas are separated by 0.02mm thick pipes, which is conducive to programming, cutting and removing cutting waste.

[0024] The advantages of the present invention are:

[0025] The anti-splash block of the present invention has a rotating circular plate that can rotate axially in a rotating circular groove. During the rotation, the rotating convex strip and the rotating groove also rotate in the same direction. The intersection between the rotating convex strip and the rotating groove can prevent the joint blocks from falling off. The central angle of the part of the rotating circular plate located in the rotating circular groove exceeds 180° to prevent the rotating circular plate from falling off from the rotating circular groove. The rotating axes of adjacent joint blocks are perpendicular to each other, which can realize multi-angle and multi-directional bending of the anti-splash block. There is no need to connect the joint blocks in series with pins or rivets. After cutting directly with a laser cutting machine, an integrated multi-directional rotatable anti-splash block can be obtained. No assembly is required and it can be formed in one piece, thereby reducing production cost and time.

[0026] The avoidance space is used to avoid the rotation of adjacent joint blocks and achieve a larger rotation angle;

[0027] The present invention can quickly shorten the production cycle of the anti-splash block. Generally, the cutting can be completed in about ten minutes, which is at least two or three days compared with the previous processing cycle. Since the more joint blocks are required, the longer the cycle, the anti-splash block of the present invention can be produced quickly, and the production cycle is not greatly affected by the number of joint blocks;

[0028] After clamping the tube parts in the laser cutting machine, insert the iron rod into the tube parts to prevent the joint blocks from swinging greatly after cutting.

[0029] On the one hand, the area cutting meets the programming needs of the laser cutting machine itself, and on the other hand, it is convenient for blanking. Therefore, adjacent areas are separated by 0.02mm thick pipes, which is conducive to programming, cutting and removing cutting waste. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in combination with the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Embodiment 1:

[0043] like Figure 1 , Figure 2 As shown, an integrated anti-splash block capable of rotating in multiple faces and angles comprises a plurality of joint blocks 1 capable of being rotatably connected in sequence, the rotation axes of adjacent joint blocks 1 being perpendicular to each other, and the joint blocks 1 being of a tubular structure as a whole; one end of the joint block 1 comprises a rotating circular plate 11 and a rotating convex strip 12 extending along the axial direction of the joint block 1, and the other end of the joint block 1 comprises a rotating circular groove 13 and a rotating groove 14 opened along the axial direction of the joint block 1; the rotating circular plate 11 is located in the rotating circular groove 13, and the central angle corresponding to the portion of the rotating circular plate 11 located in the rotating circular groove 13 exceeds 180°; the rotating convex strip 12 is inserted into the rotating groove 14.

[0044] Specifically, in this embodiment, the joint block 1 can be a square tube 3 or a round tube. In this embodiment, the square tube 3 is taken as an example. Figure 2 As shown, the joint block 1 is a structure that is symmetrical in the X plane, the Y plane, and the Z plane. The four ridges on the outer surface of the joint block 1 are arc-shaped. The top of the joint block 1 includes two rotating circular plates 11, which are symmetrically arranged and respectively located on the two sides of the joint block 1. The bottom of the rotating circular plates 11 is also connected to a small transition section. The other two sides of the top of the joint block 1 include rotating ridges 12. There are two rotating ridges 12 on each side. The rotating ridges 12 are rectangular. The two rotating ridges 12 are arranged at intervals, and the rotating ridges 12 and the rotating circular plates 11 are arranged at intervals.

[0045] The bottom end of the joint block 1 includes two rotating circular grooves 13, which are located below the rotating convex strip 12. The rotating circular groove 13 is a major arc groove, and the chamfer 131 is formed between the rotating circular groove 13 and the bottom surface to reduce the interference between the rotating circular groove 13 and the rotating circular plate 11 after rotation.

[0046] There are two rotating circular grooves 13, which are symmetrically arranged. The bottom end of the joint block 1 also includes four rotating grooves 14, two rotating grooves 14 on each side, and the rotating grooves 14 are located below the rotating circular plate 11. The number of the rotating grooves 14 is the same as the number of the rotating ridges 12, and the rotating ridges 12 can be inserted into the rotating grooves 14 and rotate and cross each other.

[0047] like Figure 4 As shown, it can be seen that when all the joint blocks 1 of the integrated anti-splash block capable of rotating in multiple faces and angles are connected in sequence, the rotating circular plate 11 is located in the rotating circular groove 13, and the central angle of the part of the rotating circular plate 11 located in the rotating circular groove 13 exceeds 180°, that is, the rotating circular plate 11 is located in the rotating circular groove 13 in an area exceeding the general area, which can ensure that the rotating circular plate 11 will not run out of the rotating circular groove 13 along the Z and Y directions. At the same time, the rotating convex strip 12 is inserted into the rotating groove 14, and the rotating convex strip 12 and the rotating groove 14 are arranged in a cross manner, which can ensure that the rotating circular plate 11 will not run out of the rotating circular groove 13 in the X direction.

[0048] like Figure 5 As shown in the figure, when some joint blocks 1 of the integrated anti-splash block capable of rotating in multiple directions and at multiple angles rotate, the rotating circular plate 11 rotates along the axial direction of the rotating circular plate 11 in the rotating circular groove 13, and at the same time, the rotating convex strips 12 and the rotating grooves 14 of the joint block 1 also rotate to form a cross shape. And because the central axes of the rotating circular plates 11 of adjacent joint blocks 1 are in a vertical state in space, Figure 5 As shown, the integrated anti-splash block that can rotate in multiple directions and at multiple angles can rotate in a single direction to form an arc structure, or it can be rotated in a single direction to form an arc structure. Figure 6 As shown, a multi-angle and multi-directional rotation is formed, such as Figure 7 As shown, the one-piece anti-splash block that can rotate in multiple faces and angles can adapt to tube products 2 that are bent at multiple angles.

[0049] The gap between the rotating circular plate 11 and the rotating circular groove 13 is greater than or equal to 0.1 mm. The gap between the rotating ridge 12 and the rotating circular groove 13 is 5%-70% of the wall thickness of the joint block 1. The wall thickness of the joint block 1 exceeds 2 mm.

[0050] like Figure 4 As shown, there are a plurality of avoidance spaces 15 between the adjacent joint blocks 1. The avoidance spaces 15 are mainly present at the connection between the adjacent joint blocks 1. The avoidance spaces 15 are used for the adjacent joint blocks 1 to avoid each other during rotation and achieve a larger rotation angle.

[0051] It should be noted that: Figure 8 As shown, the end of the joint block 1 can be ended with an incomplete joint block 1. Specifically, part of the rotating circular plate 11 and the rotating convex strip 12 can be cut off to form a neat end.

[0052] In the anti-splash block of this embodiment, the rotating circular plate 11 can rotate axially in the rotating circular groove 13. During the rotation, the rotating ridge 12 and the rotating groove 14 also rotate in the same direction; the intersection between the rotating ridge 12 and the rotating groove 14 can prevent the joint blocks 1 from falling off, and the central angle corresponding to the part of the rotating circular plate 11 located in the rotating circular groove 13 exceeds 180° to prevent the rotating circular plate 11 from falling off from the rotating circular groove 13; the rotation axes of adjacent joint blocks 1 are perpendicular to each other, which can realize multi-angle and multi-directional bending of the anti-splash block. There is no need to connect the joint blocks 1 in series with pins or rivets. After cutting directly with a laser cutting machine, an integrated multi-directional rotatable anti-splash block can be obtained. No assembly is required, and it can be processed and formed in one piece, which solves the production cost and time.

[0053] Embodiment 2:

[0054] The invention discloses a method for manufacturing an integrated anti-splash block capable of rotating on multiple surfaces and at multiple angles. The integrated anti-splash block capable of rotating on multiple surfaces and at multiple angles is obtained by laser cutting a pipe component.

[0055] Specifically, the first step is to use a square tube 3 of appropriate size (such as Figure 5 As shown) or a round tube (generally 5mm-20mm smaller than the inner diameter of the product on one side, which can be easily inserted into the product), this embodiment takes the square tube 3 as an example for explanation. The wall thickness of the square tube 3 is as thick as possible to exceed 2mm (generally, the cost of a 5m long square tube 3 is about 10 yuan to 20 yuan), and the shape of the square tube 3 is first designed by software, with the square tube 3 as the column (the method of the round tube is the same).

[0056] Design method: A rotating circular plate 11 is designed on each of the two opposite surfaces of the square tube 3, so that the joint block 1 rotates axially with the rotating circular plate 11, and the other two side surfaces are designed with a rotating groove 14 and a rotating convex strip 12 to prevent separation; a rotating circular groove 13 is designed for the adjacent joint block 1 inlaid with the rotating circular plate 11, and the specific structure is referred to Example 1. The software drawing cuts off the part that interferes with the rotation to form multiple avoidance spaces 15. The rotating groove 14 and the rotating convex strip 12 can prevent the joint blocks 1 from falling off, and after being manufactured, the joint block 1 rotates axially with the rotating circular plate 11, and the rotating groove 14 and the rotating convex strip 12 rotate alternately.

[0057] Step 2: Use the programming software of the laser cutting machine to program the designed shape (those who have laser cutting machines will have matching programming software, and you can use the existing technology);

[0058] Step 3: The square tube 3 is clamped in the laser cutting machine 5, and then a thin iron rod 4 is inserted into the square tube 3 (the purpose is to prevent the joint block 1 from swinging greatly after cutting, such as Fig.10 Through the prepared program, the square tube 3 can be directly cut into the desired shape by the laser cutting machine 5 (such as Figure 5 , Figure 6 shown).

[0059] However, before compiling the program, it is necessary to divide the joint blocks 1 of the designed splash-proof block into different areas, such as Fig. 9 As shown, the gap between the rotating circular plate 11 and the rotating circular groove 13 increases the segment 6, and the gap between the rotating convex strip 12 and the rotating circular groove 13 increases the segment 6. The thickness of the segment 6 is 0.02mm, otherwise the program cannot be compiled, and the segment 6 will melt during the laser cutting process. The segments are separated by 0.02mm thick segments (such as Figure 8 and Fig. 9 As shown in the figure, on the one hand, it adapts to the programming needs of the laser cutting machine itself (both counterclockwise and clockwise are required during the tool movement), and on the other hand, it is convenient for blanking. Therefore, adjacent areas are separated by 0.02mm thick pipes, which is conducive to programming, tool movement and removal of cutting waste.

[0060] The following points should be noted in design and programming:

[0061] The program needs to be closed loop, and the gap between the rotating circular plate 11 and the rotating circular groove 13 in the design circle should be ≥ 0.1 mm, in order to ensure smooth rotation;

[0062] The gap between the rotating convex strip 12 and the rotating circular groove 13 can be enlarged a little, so that the range of rotation will be larger and the types of products can be used. The gap between the rotating convex strip 12 and the rotating circular groove 13 is T×5%--T×70% of the wall thickness. The size of this gap can be adjusted according to needs, but at least 0.6mm is reserved;

[0063] This embodiment quickly shortens the production cycle of the anti-splash block. Generally, the cutting can be completed in about ten minutes, compared with the previous processing cycle of at least two or three days. Since the more joint blocks 1 are required, the longer the cycle, the anti-splash block of the present invention can be produced quickly, and the production cycle is not greatly affected by the number of joint blocks.

[0064] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
