Metal processing device and processing method thereof

Abstract

The invention discloses a metal processing device and a processing method thereof, belonging to the technical field of metal processing equipment. The device can utilize the matching arrangement of a magnet and a compression spring so that the detection sleeve can be installed on the welding position inside a stainless steel pipe by utilizing magnetic force, and a closed cavity is formed at the welding position. When a leak occurs at the welding position, gas is released under the restoring force of the compression spring, and a smoke ball is punctured at the same time, thereby forming white smoke, which is discharged from the welding leak along with the gas, visually helping a worker to quickly find a tiny leak so as to directly perform repair welding. The emergence of white smoke can also achieve the purpose of repair welding detection to a certain extent, thereby improving work efficiency. In addition, through the arrangement of the detection paper, after encountering white smoke, it can play a role of long-term marking, thereby avoiding losing the opportunity to observe the welding leak due to the absence of the worker when the white smoke emerges.

Description

Technical Field

[0001] The present invention relates to the technical field of metal processing equipment, and more specifically, to a metal processing device and a processing method thereof. Background Art

[0002] Pure metals are generally solid at room temperature (except mercury), have a metallic luster (i.e., strongly reflect visible light), and most are excellent conductors of electricity and heat. They are ductile, have a high density, and a high melting point. The earth's metal resources are widely present in the earth's crust and oceans. Except for a few very inactive metals such as gold and silver that exist in elemental form, the rest exist in the form of compounds. Metals are widely present in nature and are extremely commonly used in life. In modern industry, they are a very important and most widely used type of substance, among which metal materials include stainless steel.

[0003] When processing stainless steel pipes, they need to be welded. In the process of welding stainless steel pipes, welding leaks may occur, resulting in leaks in the welds. The existing method is to put the stainless steel pipes into water and ventilate both ends of the stainless steel pipes, and judge the area causing welding leaks by observing the bubbles in the water.

[0004] However, although this method can detect leaks, the stainless steel pipe must be wiped dry first after being taken out of the water. In addition, for small leaks, the staff also need to carefully search for them with the naked eye, and after the repair welding is completed, it needs to be put into water for re-inspection. This is not only inefficient, but also increases the workload. Therefore, a metal processing device and a processing method thereof are proposed. Summary of the invention

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide a metal processing device and a processing method thereof. The present invention can utilize the matching arrangement of a magnet and a compression spring so that it can utilize magnetic force to install the detection sleeve to the welding point inside the stainless steel pipe and form a closed cavity at the welding point. When a leak occurs at the welding point, the gas is released under the restoring force of the compression spring, and the smoke ball is punctured at the same time, thereby forming white smoke, which is discharged from the welding leak along with the gas, visually helping the staff to quickly find the tiny leak so as to directly carry out the repair welding. The emergence of white smoke can also achieve the purpose of repair welding detection to a certain extent, thereby improving work efficiency. In addition, through the setting of the detection paper, after encountering white smoke, it can play a role of long-term marking, avoiding the loss of opportunity to observe the welding leak due to the absence of the staff when the white smoke emerges.

[0006] To solve the above problems, the present invention adopts the following technical solutions.

[0040] Embodiment 1:

[0041] See also Figure 1-6A metal processing device and a processing method thereof include a stainless steel tube 1, a detection sleeve 2 is installed inside the stainless steel tube 1, the detection sleeve 2 includes a detection tube 21, two sealing air bags 22 are fixedly connected to the side wall of the detection tube 21, a gas cylinder 3 is fixedly connected inside the detection tube 21, a movable plug 31 is slidably connected inside the gas cylinder 3, a compression spring 32 is fixedly connected between the upper side wall of the movable plug 31 and the detection tube 21, a push rod 33 is fixedly connected to the lower side wall of the movable plug 31, and two connecting rods are fixedly connected between the detection tube 21 and the gas cylinder 3. The connecting pipe 34 is connected to the air cylinder 3 and the air bag 22 is connected to the air cylinder 3 through the connecting pipe 34. The lower side wall of the detection tube 21 is provided with a one-way valve pipe 7 located at the lower side of the movable plug 31. The air cylinder 3 is provided with a thorn ball block 4 located at the lower side of the movable plug 31. The thorn ball block 4 includes a locking block 41. The left and right side walls of the locking block 41 are both slidably connected with a plug rod 42. The inner walls of the left and right sides of the air cylinder 3 are both provided with a socket matching the plug rod 42. The plug rod 42 is inserted into the socket. A connecting rope 45 is fixedly connected between the two plug rods 42. The locking block A plurality of evenly distributed thorn needles 46 are fixedly connected to the lower side wall of 41, a smoke ball 6 is installed inside the gas cylinder 3, a sliding mesh sleeve 8 is sleeved on the stainless steel tube 1, a magnet 9 is fixedly connected to the upper side wall of the movable sleeve 81, a magnet block is embedded inside the movable plug 31, and the magnet block and the magnet 9 are magnetically attracted to each other. When in use, first, the staff sleeves the sliding mesh sleeve 8 to the end of the stainless steel tube 1, and puts the detection sleeve 2 into the stainless steel tube 1, and uses the magnetic force of the magnet 9 to attract the magnet block inside the movable plug 31, thereby driving the detection The testing sleeve 2 moves, and the staff moves the sliding mesh sleeve 8 to the welding seam. At this time, the testing sleeve 2 is also moved to the inside of the welding seam of the stainless steel pipe 1. Then the staff rotates the sliding mesh sleeve 8, so that after the magnet block inside the movable plug 31 loses the magnetic force of the magnet 9, the restoring force of the compression spring 32 is used to push the movable plug 31 downward, so that the gas inside the gas cylinder 3 is discharged into the sealing airbag 22 through the connecting pipe 34 under pressure, causing the sealing airbag 22 to expand, thereby sealing both sides of the welding place. Figure 6 As shown, it is worth noting that during the period when the gas enters the sealing airbag 22 and causes the sealing airbag 22 to expand, the one-way valve inside the one-way valve tube 7 is not enough to be opened. When the welding position is in a sealed state, the gas inside the gas cylinder 3 cannot be discharged, so that the movable plug 31 still stays above the thorn ball block 4. When a welding leak occurs at the welding position, the cavity between the two sealing airbags 22 inside the stainless steel tube 1 is not in a sealed state, which allows the air inside the gas cylinder 3 to continue to be discharged and opens the one-way valve inside the one-way valve tube 7, which allows the movable plug 31 to continue to move downward, and the remaining gas is discharged from the welding leak. When the push rod 33 approaches the thorn ball block 4, the push rod 33 is used to push the connecting rope 45 on the thorn ball block 4, as shown in FIG. Figure 7 As shown, the two plug rods 42 are moved inward, so that the plug rods 42 are separated from the insertion holes on the inner walls of the left and right sides of the cylinder 3, as shown in FIG. Figure 7As shown, after the limit of the locking block 41 is released, it starts to fall and punctures the smoke ball 6.

[0042] See also Figure 5 The smoke ball 6 includes a sealed storage ball 61, a diaphragm 62 is fixedly connected inside the sealed storage ball 61, and the sealed storage ball 61 is filled with ammonium chloride 63 and concentrated ammonia water 64 located on the upper and lower sides of the diaphragm 62, respectively, so that a large amount of white smoke is generated after the ammonium chloride 63 and the concentrated ammonia water 64 are mixed. The white smoke is ammonium chloride gas, which is discharged through the welding leak. Figure 8 As shown, the sliding mesh sleeve 8 is passed through, thereby helping the staff to better find the position of the welding leak. At this time, the sliding mesh sleeve 8 can be moved to continue welding the welding leak until the white smoke cannot be emitted.

[0043] See also Figure 1 The sliding mesh sleeve 8 includes a movable sleeve 81 sleeved on the stainless steel pipe 1, and a detection paper 82 is fixedly connected at the center of the movable sleeve 81. The detection paper 82 is made of red litmus paper, and the red litmus paper is wetted. After the red litmus paper encounters ammonium chloride gas, the alkalinity of the ammonium chloride gas turns the red litmus paper blue, thereby playing a long-term marking role, avoiding the loss of opportunity to observe the welding leak due to the absence of staff after white smoke. After the welding leak is repaired, the sliding mesh sleeve 8 is rotated again, so that the magnet 9 is attracted to the magnet block again, and the sliding mesh sleeve 8 can be pulled out, and the detection sleeve 2 is taken out by magnetic force.

[0044] See also Figure 1-3 A ball replenishing cylinder 10 is fixedly connected to the side wall of the gas cylinder 3, and a sealing cap is threadedly connected to the end of the ball replenishing cylinder 10 away from the gas cylinder 3, so as to replenish the smoke ball 6 at a later time.

[0045] See also Figure 3 A pull rope 5 is fixedly connected between the locking block 41 and the movable plug 31 , and the pull rope 5 can be used to reset the thorn ball block 4 .

[0046] See also Figure 4 Two spring plates 43 located between two plungers 42 are fixedly connected inside the locking block 41, and a return spring 44 is fixedly connected between the plunger 42 and the spring plate 43. The surface of the plunger 42 is polished and ground. Two pulleys are installed inside the locking block 41, and the two pulleys are connected with the connecting rope 45, which can trigger the release of the limit when a leak occurs at the welding point.

[0047] A metal processing device and a processing method thereof, comprising the following steps:

[0048] S1: The staff sets the sliding mesh sleeve 8 with the magnet 9 facing upward onto the stainless steel pipe 1, and places the detection sleeve 2 with the ball replenishing tube 10 facing downward inside the stainless steel pipe 1, and uses the magnetic force of the magnet 9 to attract the detection sleeve 2, and drags the detection sleeve 2 to the welding position of the stainless steel pipe 1;

[0049] S2: Rotate the sliding mesh sleeve 8, then wait for 1-2 minutes to observe whether white smoke appears at the weld, and observe whether the detection paper 82 turns blue;

[0050] S3: When white smoke appears, it means that there is a leak in the weld. Repair welding should be performed to prevent the white smoke from coming out.
