Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing technology, and in particular to a heat treatment device for stainless steel pipe fittings. Background Technology

[0002] Stainless steel pipe fittings are heat-treated by heating and cooling to improve their mechanical properties, corrosion resistance, and processing performance, enabling them to be used in a wider range of applications. Stainless steel pipe fittings come in many varieties and lengths, and are often cut into shorter pieces to meet specific usage requirements. Longer stainless steel pipe fittings require larger-scale heat treatment equipment for heat treatment.

[0003] An existing patent (publication number: CN118028586B) discloses a heat treatment device for stainless steel pipe fittings. This device mounts multiple pipe fittings onto a support assembly, and then fixes each fitting in place using a fixing assembly. At this point, the multiple pipe fittings are independent and do not overlap or obstruct each other. The support unit, along with the pipe fittings, is then mounted on a conveying unit. The conveying unit transports the pipe fittings from the furnace inlet to the furnace outlet. During the conveying process, a flame nozzle sprays flames to heat-treat each pipe fitting, ensuring that each fitting is fully heated or kept at a constant temperature. In implementing this solution, the following problems were found in the existing technology, which have not been adequately resolved:

[0004] During use, the pipe fittings need to be adjusted and fixed sequentially. When there are a large number of pipe fittings in a batch, the operation is cumbersome and affects work efficiency. Furthermore, it cannot be flexibly adjusted according to the condition of the pipe fittings, which greatly limits its use. Utility Model Content

[0005] To address the aforementioned issues of cumbersome pipe fitting fixing procedures and the inability to flexibly adjust the fitting quantity, this utility model provides a heat treatment device for stainless steel pipe fittings.

[0006] This utility model provides a heat treatment device for stainless steel pipe fittings, which adopts the following technical solution:

[0007] A heat treatment device for stainless steel pipe fittings includes a placement plate, a nozzle is arranged above the placement plate, a driving mechanism is also arranged above the placement plate, connecting pipes are arranged on both sides of the driving mechanism, a support block is arranged on the outer side of the connecting pipe, an auxiliary rod is connected to the outer side of the support block, a base plate is connected to the outer side of the auxiliary rod, a driving rod is connected to the outer side of the base plate, a gripping block is connected to the outer side of the driving rod, and an installation block is also connected to the outer side of the driving rod.

[0008] The mounting block is internally connected to a return spring, the outside of which is connected to a top plate, the outside of which is connected to a torsion spring, the inside of which is connected to a movable block, the outside of which is connected to an anti-detachment block, and elastic blocks are provided around the movable block.

[0009] The above technical solution facilitates the quick adjustment of the installation block's position by using a drive rod and support block. The position and number of installation blocks can be flexibly changed according to the pipe fittings. Furthermore, the combination of multiple movable blocks and anti-detachment blocks ensures that the pipe fittings can be fixed simply by insertion, thus improving installation and disassembly efficiency.

[0010] Optionally, in the above-mentioned stainless steel pipe heat treatment device, the mounting block is connected to the connecting pipe by a sliding connection, the mounting blocks are evenly and equidistantly distributed on the outside of the connecting pipe, and the mounting block is connected to the drive rod by a threaded connection.

[0011] The above technical solution facilitates the use of the mounting block and the drive rod to fix the mounting block in place.

[0012] Optionally, in the above-mentioned stainless steel pipe heat treatment device, the gripping block and the drive rod are integrally installed, the drive rod and the base plate are integrally installed, auxiliary rods are symmetrically distributed on both sides of the base plate, and the auxiliary rods and the support block are integrally installed.

[0013] The above technical solution facilitates bidirectional support of the drive rod via the support block, preventing the mounting block from moving during use.

[0014] Optionally, in the above-mentioned stainless steel pipe heat treatment device, the reset springs are evenly and equidistantly distributed around the center of the mounting block, the mounting block and the top plate form a spring reset structure through the reset springs, and elastic blocks are evenly and equidistantly distributed on the inner side of the mounting block.

[0015] The above technical solution facilitates the movement of the top plate by means of a reset spring, ensuring that the top plate can move inward when the pipe is inserted.

[0016] Optionally, in the above-mentioned stainless steel pipe heat treatment device, the top plate and the mounting block are connected by a sliding connection, the top plate and the torsion spring are integrally installed, the torsion spring and the movable block are integrally installed, and the movable block and the top plate are connected by a rotational connection.

[0017] The above technical solution facilitates the rotation of the movable block outward by the torsion spring, thereby fitting it inside the pipe and limiting its position.

[0018] Optionally, in the above-mentioned stainless steel pipe heat treatment device, the movable block and the anti-detachment block are installed as an integral unit, the movable block is evenly and equidistantly distributed inside the elastic block, and the outer side of the anti-detachment block is coated with an anti-slip layer.

[0019] The above technical solution facilitates the use of anti-detachment blocks and anti-slip layers to ensure stability during the fixing of pipe fittings and prevent pipe fittings from falling off.

[0020] In summary, this utility model has at least one of the following beneficial effects:

[0021] By setting a drive rod on the inner side of the mounting block and cooperating with the support block, the drive rod rotates and drives the support block to move, so that the connection between the mounting block and the connecting pipe is disengaged. At this time, the density of the mounting block can be changed according to the size of the pipe to adapt to different situations. The support block supports the mounting block to ensure the stability of the movable connection.

[0022] By setting elastic blocks and movable blocks around the mounting block, the elastic blocks are funnel-shaped. During use, the pipe is inserted into the mounting block, so that the movable block is inside the pipe. At the same time, because the pipe isolates the elastic block and the movable block, the movable block is pushed outward by the torsion spring, so that the movable block and the anti-detachment block are inside the pipe, thus completing the fixed and limited work of the pipe.

[0029] The following is combined with Figure 1-5The present invention will be described in further detail below.

[0030] Please refer to the attached diagram in the instruction manual. Figure 1-5 This utility model provides an embodiment of a heat treatment device for stainless steel pipe fittings, including a placement plate 1, a nozzle 2 above the placement plate 1 for heating, ensuring ease of use, a drive mechanism 4 above the placement plate 1, connecting pipes 3 on both sides of the drive mechanism 4, a support block 10 on the outer side of the connecting pipe 3, an auxiliary rod 9 connected to the outer side of the support block 10, the auxiliary rod 9 and the support block 10 are used to fix both sides to ensure stability, a base plate 8 is connected to the outer side of the auxiliary rod 9, a drive rod 7 is connected to the outer side of the base plate 8, a grip block 6 is connected to the outer side of the drive rod 7, the position can be changed by the drive rod 7 and the grip block 6 for easy adjustment, and an installation block 5 is also connected to the outer side of the drive rod 7.

[0031] The mounting block 5 is internally connected to a return spring 11. The outside of the return spring 11 is connected to a top plate 13. The movement of the top plate 13 drives the movable block 15 to move, which is convenient for subsequent use. The outside of the top plate 13 is connected to a torsion spring 14. The inside of the torsion spring 14 is connected to the movable block 15. The outside of the movable block 15 is connected to an anti-detachment block 16. The anti-detachment block 16 increases friction and prevents the pipe from moving. Elastic blocks 12 are provided around the movable block 15.

[0032] Working principle: In use, first, according to the size of the pipe fitting, grasp the gripping block 6 and rotate it, so that the gripping block 6 drives the drive rod 7 to rotate, and causes a threaded movement with the mounting block 5, so that the base plate 8 and the support block 10 are separated from the connecting pipe 3. Then move the mounting block 5 to ensure that the spacing between the mounting blocks 5 can maximize the use of multiple mounting blocks 5. Then rotate the gripping block 6 in the opposite direction so that the base plate 8 and its bottom support block 10 fit against the outside of the connecting pipe 3, thus completing the fixation of the mounting block 5.

[0033] As described above, when the pipe needs to be installed, the pipe is inserted into the installation block 5. First, the pipe enters the installation block 5, at which point the movable block 15 is inside the pipe. As the pipe continues to go deeper, it squeezes the elastic block 12, releasing the elastic block 12 from limiting the movable block 15. Driven by the torsion spring 14, the movable block 15 moves outward, so that the anti-detachment block 16 fits tightly against the inside of the pipe, forming a triangular chuck-like structure, thus completing the fixing of the pipe. After heating is complete, the pipe can be directly pulled out.

[0034] It should be noted that the specific working methods of the placement plate 1, nozzle 2, and drive mechanism 4 can be found in the comparative patent; only the necessary basic features are present here.

[0035] It should be further explained that the mounting block 5 is connected to the connecting pipe 3 by a sliding connection. The mounting blocks 5 are evenly and equidistantly distributed on the outside of the connecting pipe 3. The mounting block 5 is connected to the drive rod 7 by a threaded connection. The mounting block 5 can be fixed by the drive rod 7 through the cooperation of the mounting block 5 and the drive rod 7.

[0036] It should be noted that the grip block 6 and the drive rod 7 are installed as a single unit, the drive rod 7 and the base plate 8 are installed as a single unit, and auxiliary rods 9 are symmetrically distributed on both sides of the base plate 8. The auxiliary rods 9 and the support block 10 are installed as a single unit. The support block 10 provides bidirectional support for the drive rod 7, preventing the mounting block 5 from moving during use.

[0037] It should be further explained that the reset springs 11 are evenly and equidistantly distributed around the center of the mounting block 5. The mounting block 5 and the top plate 13 form a spring reset structure through the reset springs 11. The inner side of the mounting block 5 is evenly and equidistantly distributed with elastic blocks 12. The reset springs 11 drive the top plate 13 to move, ensuring that the top plate 13 can move inward when the pipe is inserted.

[0038] It should be further explained that the top plate 13 is connected to the mounting block 5 by a sliding connection, the top plate 13 is integrated with the torsion spring 14, the torsion spring 14 is integrated with the movable block 15, and the movable block 15 is connected to the top plate 13 by a rotational connection. The torsion spring 14 drives the movable block 15 to rotate outward, thereby fitting inside the pipe fitting and limiting the pipe fitting.

[0039] It should be noted that the movable block 15 and the anti-detachment block 16 are installed as a single unit. The movable block 15 is evenly and equidistantly distributed inside the elastic block 12. The outer side of the anti-detachment block 16 is coated with an anti-slip layer. The anti-detachment block 16 and the anti-slip layer work together to ensure stability during the fixing of the pipe fitting and prevent the pipe fitting from falling off.

[0040] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
