Description

Technical Field

[0001] The utility model relates to the technical field of magnesium alloy production, in particular to a magnesium alloy melt infusion pipe. Background Art

[0002] Due to its light weight, high strength and good mechanical properties, magnesium alloy is widely used in the fields of aerospace, automobile manufacturing, electronic equipment, etc. The production of magnesium alloy products is formed by die-casting machines, and the feeding of die-casting machines is obtained from a melting furnace through an infusion pipe. In the process of transporting magnesium alloy melt by the infusion pipe in the prior art, the magnesium alloy melt will burn in the infusion pipe to generate solid magnesium oxide, thus blocking the infusion pipe. At the same time, since the existing infusion pipe is integrally formed and has a 90° bend, it is difficult for workers to quickly and thoroughly clean it after the infusion pipe is blocked, which causes great inconvenience to the maintenance of the infusion pipe.

[0003] A magnesium alloy melt infusion pipe disclosed in the authorized publication number CN219443392U adds a flange at the 90° bend, dividing the original infusion pipe into two sections. When repairing the infusion pipe, only need to separate the two sections of the infusion pipe to quickly repair the infusion pipe; however, the flanges are fixed by a plurality of locking bolts, and both installation and disassembly are time-consuming and laborious. Content of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and to propose a magnesium alloy melt infusion pipe.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A magnesium alloy melt infusion pipe, comprising: a first pipe body and a second pipe body. One ends of the first pipe body and the second pipe body are respectively welded with a first flange and a second flange. The outer circumferences of the first flange and the second flange are respectively provided with a first socket and a second socket. The same plug rod is horizontally inserted into the first socket and the second socket. One end of the plug rod is welded with a limiting block;

[0007] A fixing structure for fixing the plug rod and the first flange and the second flange together inside the plug rod;

[0008] A disassembly mechanism for disassembling the plug rod.

[0009] As a further technical solution of the utility model, the other ends of the first pipe body and the second pipe body are respectively communicated with an air outlet pipe and an air inlet pipe, and valves are fixedly installed on both the air outlet pipe and the air inlet pipe.

[0010] As a further technical solution of the present utility model, four first sockets, four second sockets and four insertion rods are provided. The four first sockets and the four second sockets are respectively evenly distributed along the circumference on the outer peripheries of the first flange and the second flange, and the four insertion rods are respectively located in the four first sockets and the four second sockets.

[0011] As a further technical solution of the present utility model, the fixing structure includes a clamping block and a second spring. A groove is formed at the front end of the insertion rod. The bottom end of the second spring is welded to the inner bottom of the groove, and the clamping block is welded to the top end of the second spring. The clamping block is slidably connected to the groove, and the front side of the clamping block is an inclined surface.

[0012] Align the front end of the insertion rod with the first socket and the second socket and insert it. The inner walls of the first socket and the second socket squeeze the inclined surface at the front end of the clamping block, squeeze the clamping block against the inner wall of the groove to compress and deform the second spring. When the front end of the insertion rod passes through the first socket and the second socket, the clamping block loses the squeezing force, and the clamping block pops out of the groove under the elastic force of the second spring. The rear side of the clamping block abuts against the side surface of the second flange, so that the insertion rod can no longer be separated from the inside of the first socket and the second socket, and the insertion rod is tightly fixed inside the first socket and the second socket, completing the installation and fixation between the first flange and the second flange. The installation steps are simple, time-saving and labor-saving.

[0013] As a further technical solution of the present utility model, the disassembly mechanism includes a squeezing block and a pushing ring. Four squeezing blocks are provided and are respectively located on the sides of the four second sockets. An arc-shaped connecting rod is welded between every two adjacent squeezing blocks. A screw rod horizontally penetrates through one of the arc-shaped connecting rods. The screw rod is threadedly connected to the arc-shaped connecting rod. One end of the screw rod is rotatably connected to the second flange, and a limiting rod horizontally penetrates through the other three arc-shaped connecting rods. The limiting rod is slidably connected to the arc-shaped connecting rod. One end of the limiting rod is welded to the second flange. A fixed ring is welded to the outside of the first flange. A first spring is horizontally welded to the side surface of the fixed ring. Four first springs are provided and are evenly distributed along the circumference on the side surface of the fixed ring. The pushing ring is welded to the other ends of the four first springs. The pushing ring is slidably connected to the outside of the first flange.

[0014] When disassembly is required, rotate the screw rod to drive one arc-shaped connecting rod to move forward. Then one arc-shaped connecting rod drives the four squeezing blocks to move forward through the connected squeezing block and the other three arc-shaped connecting rods. The four squeezing blocks squeeze the inclined surfaces of the four clamping blocks and then squeeze the four clamping blocks into the groove, so that the insertion rod loses the limiting force, facilitating the removal of the insertion rod from the first socket and the second socket. Then push the pushing ring forward. The pushing ring squeezes the four limiting blocks to move forward, thereby driving the four insertion rods to move out of the first socket and the second socket. The four insertion rods can be disassembled together, and the disassembly steps are also relatively simple, time-saving and labor-saving.

[0015] The beneficial effects of the present utility model are as follows: The installation and fixation between the first flange and the second flange can be completed only by inserting four insertion rods. The installation steps are simple, time-saving and labor-saving; and the four insertion rods can be disassembled together, and the disassembly steps are also relatively simple, time-saving and labor-saving.

[0026] Please refer to the appendix Figure 1-2 , in a preferred embodiment, the other ends of the first pipe body 1 and the second pipe body 7 are respectively communicated with an air outlet pipe 10 and an air inlet pipe 9, and valves 8 are fixedly installed on both the air outlet pipe 10 and the air inlet pipe 9.

[0027] After the magnesium alloy melt infusion pipe is installed and when it is necessary to transport the magnesium alloy melt, open the valves on the air outlet pipe 10 and the air inlet pipe 9, and introduce inert gas into the magnesium alloy melt infusion pipe from the air inlet pipe 9. The inert gas will squeeze the air in the magnesium alloy melt infusion pipe out from the air outlet pipe 10, preventing the magnesium alloy melt from burning in the infusion pipe to produce solid magnesium oxide and blocking the infusion pipe.

[0028] Please refer to the appendix Figure 4 , in a preferred embodiment, there are four first sockets 19, four second sockets 18 and four insertion rods 16. The four first sockets 19 and the four second sockets 18 are respectively evenly distributed along the circumferences on the outer perimeters of the first flange 12 and the second flange 2, and the four insertion rods 16 are respectively located in the four first sockets 19 and the four second sockets 18.

[0029] Please refer to the appendix Figure 4 , in a preferred embodiment, the fixing structure includes a clamping block 21 and a second spring 22. A groove 20 is formed at the front end of the insertion rod 16. The bottom end of the second spring 22 is welded to the inner bottom of the groove 20, the clamping block 21 is welded to the top end of the second spring 22, the clamping block 21 is slidably connected to the groove 20, and the front side of the clamping block 21 is an inclined surface 4.

The limiting rod 17 is slidably connected to the arc-shaped connecting rod 3, and one end of the limiting rod 17 is welded to the second flange 2.

[0032] The limiting rod 17 limits the movement of the arc-shaped connecting rod 3 and the pressing block 6, so that they can only move forward and cannot rotate together with the screw rod 5.

[0033] Please refer to the appendixFigure 1-4 In a preferred embodiment, a fixing ring 15 is welded to the outside of the first flange 12, and a first spring 14 is horizontally welded to the side of the fixing ring 15.

When the front end of the plug rod 16 passes through the first socket 19 and the second socket 18, the block 21 loses the squeezing force, and the block 21 pops out of the groove 20 under the elastic force of the second spring 22, and the rear side of the block 21 abuts against the side of the second flange 2, so that the plug rod 16 can no longer be detached from the first socket 19 and the second socket 18, and the plug rod 16 is tightly fixed inside the first socket 19 and the second socket 18, and the installation and fixation between the first flange 12 and the second flange 2 is completed, and the installation steps are simple, time-saving and labor-saving;

[0036] When disassembly is required, the screw rod 5 is rotated to drive an arc-shaped connecting rod 3 to move forward, and then the arc-shaped connecting rod 3 drives the four extrusion blocks 6 to move forward through the connected extrusion block 6 and the other three arc-shaped connecting rods 3, and the four extrusion blocks 6 squeeze the inclined surfaces of the four card blocks 21 forward and then squeeze the four card blocks 21 into the groove 20, so that the insertion rod 16 loses the restricting force, which facilitates the insertion rod 16 to move out of the first socket 19 and the second socket 18, and then the pushing ring 13 is pushed forward, and the pushing ring 13 squeezes the four limit blocks 11 forward, thereby driving the four insertion rods 16 to move out of the first socket 19 and the second socket 18, and the four insertion rods 16 can be disassembled together, and the disassembly steps are also relatively simple, time-saving and labor-saving.
