Description

Technical Field

[0001] The utility model relates to the technical field of charge fork support, in particular to a heat treatment charge fork support rod. Background Art

[0002] Heat treatment furnaces can change the internal structure of metal materials by high-temperature heating, thereby improving the hardness, strength, toughness and other physical properties of the materials, improving the microstructure of the materials, and enhancing the corrosion resistance and wear resistance of the materials. In addition, heat treatment furnaces can also be used for different heat treatment processes such as annealing, quenching, and tempering to meet the different performance requirements of metal materials. When the heat treatment furnace is working, due to the excessively high temperature inside, a material fork is required to assist in loading and unloading.

[0003] Nowadays, steel pipes are generally used as support rods for material forks. They are greatly deformed due to the influence of temperature. If the temperature of the steel pipe is too high and the steel pipe is deformed, it will affect the connected material fork, resulting in poor feeding accuracy. When the steel pipe needs to be adjusted, it is difficult to grasp and adjust due to the deformation of the steel pipe, which will affect the working efficiency of the heat treatment furnace. In addition, the poor feeding accuracy of the material fork also affects the composition of the products of the heat treatment furnace.

[0004] Therefore, it is urgent to provide a heat treatment charge fork support rod to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the disadvantages of the prior art and provide a heat treatment furnace charge fork support rod.

[0006] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a heat treatment furnace charge fork support rod, including a cooling component, a reflux component is provided on one side of the cooling component, an extension component is slidably connected in the cooling component, and a gripping component is provided on one side of the cooling component;

[0007] A flow guide component is provided on one side of the cooling component, and a positioning component is provided on one side of the flow guide component.

[0008] The utility model is further configured as follows: the cooling component includes an inner reinforcement tube, a support tube is provided on the outer side of the inner reinforcement tube, a plurality of support blocks are provided between the support tube and the inner reinforcement tube for connection, a filter ring is provided on one side of the support tube, and a slide groove is provided on one side inside the inner reinforcement tube.

[0009] Through the above technical solution, since the support tube and the inner reinforcement tube are connected by a support block, an air cavity is formed, which can allow enough cold air to enter. After the cold air is input into the support tube and the inner reinforcement tube, it can be cooled, and the filter ring isolates the air outlet to prevent foreign objects from entering.

[0010] The utility model is further configured as follows: the reflux component comprises a blocking plate, the blocking plate is fixedly connected to the support pipe, and a bracket is arranged inside the blocking plate.

[0011] Through the above technical solution, the interior of the blocking plate is in an arc-shaped structure. After the gas reaches the blocking plate from the inside of the inner reinforcement tube, it will flow back into the air cavity between the inner reinforcement tube and the support tube. In this way, the airflow has a larger contact area with the two pipes, a longer contact time, and a better cooling effect. The bracket plays a guiding role, making the airflow return more uniform and the heat dissipation effect more uniform.

[0012] The utility model is further configured as follows: the extension component includes a slide rod, the slide rod is slidably connected to the slide groove, a cavity is opened on one side of the slide rod, an insert block is provided on one side of the cavity, a clamping block is provided in the cavity, and the clamping block is fixedly connected to the inner layer reinforcement tube.

[0013] Through the above technical solution, the blocking plate is connected to one end of the material fork, so the sliding rod is the end farther away from the heat treatment furnace. However, when the temperature of the heat treatment furnace is too high, the temperature at the sliding rod will also rise very quickly. At this time, the sliding rod can be slid away from the inner reinforcement pipe to protect the cold air pipe and prevent the temperature from being too high to be inconvenient to take. The sliding rod is connected to the slide groove while being slidably connected. The sliding rod can be limited when the rotating plug block is plugged into the card block.

[0014] The utility model is further configured as follows: the gripping assembly comprises a gripping rod, the gripping rod is mounted on one side of the supporting tube, and a plurality of through holes are formed on the gripping rod.

[0015] Through the above technical solution, if the slide rod is directly operated to control the material fork, it is easy to accidentally touch the slide rod and cause it to rotate or slide, changing the originally adjusted state of the slide rod. Therefore, the grip can be used for operation, and the cold air used at the filter ring can pass through the through hole to cool the grip rod, and the exhaust gas can be used to prevent the grip rod temperature from rising too quickly.

[0016] The utility model is further configured as follows: the guide assembly comprises an air intake joint, the air intake joint is fixedly connected to the slide rod, a mounting plate is arranged inside the air intake joint, and a filling plate is embedded in the mounting plate.

[0017] Through the above technical solution, the cold air pipe is inserted into the air inlet joint, and the filling plate and the cold air pipe are pressed together to increase the friction force for limiting the position.

[0018] The utility model is further configured as follows: the positioning assembly includes an outer reinforcement tube, a connecting plate is provided on one side of the outer reinforcement tube, the connecting plate is fixedly connected to the air intake joint, a rotating shaft is provided on one side of the outer reinforcement tube, and the rotating shaft is rotatably connected to the connecting plate.

[0019] Through the above technical solution, the cold air pipe is first passed through the outer reinforcing pipe before being plugged into the air inlet joint, and the cold air pipe is limited to prevent shaking, so that the cold air pipe will not be damaged due to shaking and being too close to the heat treatment furnace. It also has better coordination when moving the support pipe and is more practical. The shaft can rotate in the connecting plate, but the rotation range is limited. In this way, the cold air pipe can rotate in a small range when adjusting the support pipe, thereby reducing the bending of the cold air pipe caused by the movement of the support pipe.

[0020] The beneficial effects of the utility model are as follows:

[0021] 1. The utility model inputs cold air into the inner layer reinforcement tube, and the cold air flows back to the inner layer reinforcement tube and the support tube through the blocking plate, and finally the cold air is discharged to take away the heat. In this way, the contact area between the cold air and the reinforcement tube and the support tube is larger, and the cold air stays in the support tube for a longer time, so the cooling effect is better and the deformation of the support tube can be effectively reduced;

[0022] 2. The utility model limits the cold air pipe through the air inlet joint and the outer reinforcement pipe, so that the cold air pipe will not swing at will, and prevent the cold air pipe from contacting the high temperature area and being damaged. At the same time, the rotation of the shaft is used to allow the cold air pipe to rotate within a certain range, reducing the possibility of bending, making the cold air pipe more stable when working, and ensuring stable and continuous cooling.

DETAILED DESCRIPTION

[0032] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0033] See also Figure 1-Figure 8 , a heat treatment furnace charge fork support rod, including a cooling component 1, such as Figure 2 As shown, the cooling component 1 includes an inner layer reinforcement tube 101, a support tube 102 is provided on the outer side of the inner layer reinforcement tube 101, a plurality of support blocks 103 are provided between the support tube 102 and the inner layer reinforcement tube 101 for connection, a filter ring 104 is provided on one side of the support tube 102, and a slide groove 105 is provided on one side of the inner layer reinforcement tube 101. Since the support tube 102 and the inner layer reinforcement tube 101 are connected by the support block 103, an air cavity is formed to allow enough cold air to enter. After the cold air is input into the support tube 102 and the inner layer reinforcement tube 101, cooling can be performed, and the filter ring 104 isolates the air outlet to prevent foreign matter from entering.

[0034] A reflux component 2 is provided on one side of the cooling component 1. Figure 3 As shown, the reflux component 2 includes a blocking plate 201, which is fixedly connected to the support tube 102. A bracket 202 is provided inside the blocking plate 201. The interior of the blocking plate 201 is an arc-shaped structure. After the gas reaches the blocking plate 201 from the inside of the inner reinforcement tube 101, it will flow back into the air cavity between the inner reinforcement tube 101 and the support tube 102. In this way, the contact area between the airflow and the two pipes is larger, the contact time is longer, and the cooling effect is better. The bracket 202 plays a guiding effect, making the airflow reflux more uniform and the heat dissipation effect more uniform.

[0035] The cooling component 1 is slidably connected with an extension component 3, such as Figure 4As shown, the extension component 3 includes a slide bar 301, which is slidably connected to the slide groove 105. A cavity 302 is provided on one side of the slide bar 301, and an insert block 303 is provided on one side of the cavity 302. A clamping block 304 is provided in the cavity 302, and the clamping block 304 is fixedly connected to the inner layer reinforcement tube 101. The blocking plate 201 is one end connected to the material fork, so the slide bar 301 is the end farther away from the heat treatment furnace. However, when the temperature of the heat treatment furnace is too high, the temperature at the slide bar 301 will also rise quickly. At this time, the slide bar 301 can be slid away from the inner layer reinforcement tube 101 to protect the cold air pipe and prevent the temperature from being too high to be inconvenient to take. The slide bar 301 is slidably connected to the slide groove 105 and is also rotatably connected. When the rotating insert block 303 is plugged into the clamping block 304, the slide bar 301 can be limited.

[0036] A gripping assembly 4 is provided on one side of the cooling assembly 1; Figure 5 As shown, the gripping assembly 4 includes a grip rod 401, which is mounted on one side of the support tube 102. A plurality of through holes 402 are provided on the grip rod 401. If the slide rod 301 is directly operated to control the material fork, it is easy to accidentally touch the slide rod 301 and cause it to rotate or slide, changing the originally adjusted state of the slide rod 301. Therefore, the grip rod 401 can be used for operation, and the cold air used at the filter ring 104 can pass through the through hole 402 to cool the grip rod 401, and the exhaust gas can be used to prevent the temperature of the grip rod 401 from rising too quickly.

[0037] A flow guide component 5 is provided on one side of the cooling component 1. Figure 6 As shown, the guide assembly 5 includes an air inlet connector 501, which is fixedly connected to the slide rod 301. A mounting plate 502 is provided inside the air inlet connector 501, and a filling plate 503 is embedded in the mounting plate 502. The cold air pipe is inserted into the air inlet connector 501, and the filling plate 503 is pressed against the cold air pipe to increase friction for limiting the position.

[0038] A positioning component 6 is provided on one side of the flow guide component 5. Figure 7 As shown, the positioning component 6 includes an outer reinforcement tube 601, one side of the outer reinforcement tube 601 is provided with a connecting plate 602, the connecting plate 602 is fixedly connected to the air inlet connector 501, one side of the outer reinforcement tube 601 is provided with a rotating shaft 603, the rotating shaft 603 is rotatably connected to the connecting plate 602, and the cold air pipe is first passed through the outer reinforcement tube 601 before being plugged into the air inlet connector 501, so as to limit the cold air pipe to prevent shaking, so that the cold air pipe will not be damaged due to shaking and being too close to the heat treatment furnace, and has better coordination when moving the support tube 102, which is more practical. The rotating shaft 603 can rotate in the connecting plate 602, but the rotation range is limited, so that the cold air pipe can be rotated in a small range when adjusting the support tube 102, thereby reducing the bending of the cold air pipe caused by the movement of the support tube 102.

[0039] When the utility model is in use, the blocking plate 201 is fixedly connected to the material fork, the cold air pipe is completely passed through the outer reinforcement tube 601 and then plugged into the air inlet joint 501, and the position of the slide bar 301 is adjusted according to the temperature of the heat treatment furnace. If the temperature is too high, the slide bar 301 is rotated to allow the block 304 to disengage from the plug block 303, and then the slide bar 301 is slid away from the support tube 102, so as to protect the cold air pipe from damage and prevent the slide bar 301 from losing its sliding ability after being deformed due to excessive temperature. After the cold air is input from the air inlet joint 501, it will pass through the entire inner reinforcement tube 101 to reach the blocking plate 201, and then the cold air will flow back from the blocking plate 201 to between the inner reinforcement tube 101 and the support tube 102, and finally be discharged to take away the hot air.
