Description

Technical Field

[0001] The invention relates to the technical field of electric heating tubes, and in particular to an electric heating tube fin inserting device. Background Art

[0002] The electric heating tube fin device is a device that adds fins to the outer surface of the electric heating tube. The electric heating tube fin device usually consists of two parts: the electric heating tube and the fin. The electric heating tube contains a resistance wire inside, which generates heat by passing electricity. The fin is tightly wound or welded on the outer surface of the electric heating tube, and is usually made of metal with good thermal conductivity, such as aluminum, copper or stainless steel.

[0003] According to the heating requirements and working environment, select fins and electric heating tubes with suitable materials, sizes and shapes. Insert the fins into the predetermined positions of the electric heating tubes, and ensure that the contact surfaces between the fins and the electric heating tubes are flat and tightly fitted. During the assembly process, pay attention to the direction and position of the fins to ensure that they are consistent with the heat transfer direction of the electric heating tubes. In some cases, welding may be required to enhance the connection strength and heat transfer efficiency between the fins and the electric heating tubes. When welding, choose appropriate welding methods and materials to ensure reliable welding quality and avoid damage to the electric heating tubes.

[0004] In the existing technical solutions, the fins are mostly set to be thinner or longer, which is conducive to heat dissipation. When the fins are plugged into the electric heating tube, the contact surface must be kept flat and tightly fitted.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0034] The present invention provides a technical solution:

[0035] See also Figure 1 , Figure 4 , Figure 6 and Figure 8 , an electric heating tube fin insertion device, comprising a plug-in frame 1 and a plug-in mechanical claw 2 located behind the plug-in frame 1, an electric heating tube 8 is detachably installed inside the plug-in frame 1, a locking top column 9 is abutted at the left end of the electric heating tube 8, the locking top column 9 is detachably connected to the plug-in frame 1, and an extrusion positioning component 6 is movably attached to the outer wall of the electric heating tube 8; the extrusion positioning component 6 comprises a third clamping seat 601 attached to the front and rear ends of the electric heating tube 8, a hydraulic cavity 602 is provided inside the third clamping seat 601, and hydraulic assembly grooves 603 are provided at both the upper and lower ends of the left side of the hydraulic cavity 602, and a fitting top column 607 is attached to the inside of the hydraulic assembly groove 603, and an extrusion top plate 605 is fixedly installed on the ends of the two fitting top columns 607 away from the hydraulic cavity 602, and an elastic liquid guide tube 604 is fixedly connected to the inside of the third clamping seat 601 away from the extrusion top plate 605, and a driving clamping component 5 is provided on the outer wall of the fixed assembly sleeve 10.

[0036] By adopting the above technical scheme, when the fin is inserted into the electric heating tube 8, the plug-in mechanical claw 2 needs to be used in conjunction. When in use, the plug-in mechanical claw 2 can grab the fin to be plugged in. After grabbing the fin, the through hole on the fin is aligned with the electric heating tube 8, thereby driving the plug-in mechanical claw 2 to plug the fin in the appropriate position of the electric heating tube 8; before plugging in, the electric heating tube 8 is plugged into the appropriate position of the plug-in frame 1. After the electric heating tube 8 is plugged in, the locking top column 9 is twisted and the locking top column 9 is threadedly installed on the plug-in frame 1. The electric heating tube 8 is tightened by the locking top column 9, so as to ensure the stability of the electric heating tube 8 during plugging. When the fin is plugged in the electric heating tube 8, since the fin is thin and long and the plug-in parts match each other, it will be easily deformed by external force during plugging. When the fin connection is deformed, the driving clamping component 5 can be elastically guided The liquid pipe 604 injects liquid into the hydraulic chamber 602. The increase of liquid inside the hydraulic chamber 602 can push the fitting top column 607 inside the hydraulic assembly groove 603 to slide. The movement of the fitting top column 607 can drive the extrusion top plate 605 to move, so that the moving extrusion top plate 605 can press the fins on the adjacent sides tightly. The extrusion effect of the extrusion top plate 605 can reset the deformation generated when the fins and the electric heating tube 8 are inserted and connected. The deformation is reset by the extrusion positioning component 6, which can ensure a close connection between the fins and the electric heating tube 8, which can facilitate subsequent welding. At the same time, the main function of the fins is to increase the heat transfer area, thereby enhancing the heat exchange effect. If there is a gap or instability in the connection between the fins and the electric heating tube 8, the heat transfer will be blocked. By resetting the deformation, a good contact between the fins and the electric heating tube 8 can be ensured, thereby improving the heat transfer efficiency.

[0037] Specifically, Figure 1 , Figure 2 , Figure 5 and Figure 8As shown, both front and rear ends of the plug-in frame 1 are provided with assembly grooves 3, an assembly shaft 4 is fixedly installed inside the assembly groove 3, a fixed assembly sleeve 10 is fixedly sleeved on the outer end surface of the assembly shaft 4, and the number of fixed assembly sleeves 10 is set in multiples, the driving clamping assembly 5 includes an assembly seat 501 fixedly installed on the upper end of the fixed assembly sleeve 10, and a photoelectric sensor 502 is fixedly installed on the outer wall of the assembly seat 501; an electric cylinder 503 is fixedly installed on the outer wall of the fixed assembly sleeve 10 close to the electric heating tube 8, and a first clamping seat 504 is fixedly installed on the telescopic end of the electric cylinder 503, and the two adjacent first clamping seats 504 can clamp the electric heating tube 8; an adjusting screw 606 is fixedly installed inside the first clamping seat 504, and the adjusting screw 60 There are two of them, and the right side of the adjusting screw 606 at the bottom end is rotatably mounted with a second clamping seat 505, and the left side of the adjusting screw 606 at the top end is rotatably connected to the third clamping seat 601; the left side of the second clamping seat 505 is embedded with a hydraulic clamping bag 508, and the right side of the elastic liquid guide tube 604 passes through the first clamping seat 504 and is interconnected with the hydraulic clamping bag 508; a hydraulic pump 506 is fixedly mounted on the left rear end of the upper end surface of the plug-in frame 1, and the output end of the hydraulic pump 506 is fixedly connected to a conveying main pipe 509, and a conduction manifold 507 is fixedly connected to the pipe wall of the conveying main pipe 509, and a plurality of conduction manifolds 507 are provided, and the conduction manifold 507 and the hydraulic clamping bag 508 are interconnected.

[0038] By adopting the above technical solution, when the plug-in mechanical claw 2 inserts the fin to be plugged into the electric heating tube 8, the fixed assembly sleeve 10 can be installed in the assembly groove 3 through the assembly shaft 4. The drive clamping component 5 and the extrusion positioning component 6 can be supported by the setting of the fixed assembly sleeve 10, and the installation position of the drive clamping component 5 and the extrusion positioning component 6 can be adjusted by the detachable connection between the fixed assembly sleeve 10 and the assembly shaft 4. The set photoelectric sensor 502 can monitor the moving fin. When the photoelectric sensor 502 detects that a fin passes through, the photoelectric sensor 502 can transmit the monitoring data to the electric cylinder 503 in front of the adjacent position, symmetrically The electric cylinder 503 can be driven to work synchronously. The operation of the electric cylinder 503 can drive the first clamping seat 504 to move. The first clamping seat 504 can drive the second clamping seat 505 and the third clamping seat 601 to clamp the electric heating tube 8 through the adjusting screw 606. In this way, the electric heating tube 8 is clamped by the clamping seat through the simultaneous movement of the fins. This can reduce the friction vibration generated by the fins when plugging the electric heating tube 8, thereby reducing the aggravation of the friction between the fins and the electric heating tube 8 caused by the vibration, and further reducing the deformation of the fins themselves when plugging. When the clamping seat is clamped, the hydraulic pump 506 is started. The hydraulic pump 506 can extract the external hydraulic pipe when it works. 6 can supply liquid to the delivery main pipe 509, and the liquid can be delivered to each conduction manifold 507 through the delivery main pipe 509, and the liquid can be introduced into the corresponding hydraulic clamping bag 508 through the conduction manifold 507. The increase of liquid in the hydraulic clamping bag 508 can make the hydraulic clamping bag 508 expand itself, and the expansion and extrusion of the hydraulic clamping bag 508 and the clamping of the clamping seat can further improve the clamping effect of the clamping seat; at the same time, the hydraulic clamping bag 508 can absorb the vibration generated when the fins on the electric heating tube 8 are plugged in through the extrusion contact with the electric heating tube 8, so that the deviation caused by the external force of the fins during the plugging can be further reduced; at the same time, the light When the electric sensor 502 has been monitoring the presence of fins, the photoelectric sensor 502 can trigger the electric cylinder 503 in front of the adjacent position to extend and retract. The first clamping seat 504, the second clamping seat 505 and the third clamping seat 601 connected to the front end of the electric cylinder 503 in front of the adjacent position have the effect of auxiliary positioning. When the fins are plugged into the appropriate position of the electric heating tube 8, the electric cylinder 503 in front of the adjacent position pushes the first clamping seat 504, the second clamping seat 505 and the third clamping seat 601 to clamp the electric heating tube 8. By making the sizes of multiple groups of first clamping seats 504, second clamping seats 505 and third clamping seats 601 the same, the plug-in distances between the fins can be ensured to be the same.When the insertion position between the fins needs to be adjusted, the adjusting screw 606 is turned, and the adjusting screw 606 can rotate on the first clamping seat 504, so that the upper and lower adjusting screws 606 can respectively push the second clamping seat 505 and the third clamping seat 601 to adjust the position, thereby changing the distance between the first clamping seat 504, the second clamping seat 505 and the third clamping seat 601, so as to adjust the insertion distance between each fin. ;

[0039] Specifically, Figures 2 to 4 and Figure 7 As shown, a clamping lubrication assembly 7 is provided on the left side inside the plug-in frame 1, and the clamping lubrication assembly 7 includes an assembly pipe groove 706 opened on the left side of the middle position inside the plug-in frame 1; a fixed hydraulic bag 702 is installed inside the assembly pipe groove 706, and the upper end of the fixed hydraulic bag 702 is fixedly connected to a clamping conveying conduit 701; a lubricating elastic sleeve 703 is abutted on the right side of the fixed hydraulic bag 702, and the upper end of the lubricating elastic sleeve 703 is fixedly connected to a one-way conveying valve tube 705, and a spray hole 704 is opened on the inner wall of the lubricating elastic sleeve 703, and a plurality of spray holes 704 are provided.

[0040] By adopting the above technical solution, when in use, when the electric heating tube 8 is plugged into the plug-in frame 1, the hydraulic pump 506 is started, and the hydraulic pump 506 can supply liquid to the delivery main pipe 509, and the liquid can be delivered to the clamping delivery conduit 701 through the delivery main pipe 509, so that the liquid can be supplied to the fixed hydraulic bag 702, and when the liquid inside the fixed hydraulic bag 702 increases, the fixed hydraulic bag 702 itself expands, and when the fixed hydraulic bag 702 expands and expands in the assembly pipe groove 706, the fixed hydraulic bag 702 can squeeze the lubricating elastic sleeve 703, and the lubricating elastic sleeve 703 is squeezed, so that the graphite powder in the lubricating elastic sleeve 703 can be sprayed out through the spray hole 704, so that the graphite powder in the lubricating elastic sleeve 703 can be fully sprayed on the outer wall of the electric heating tube 8 during the plug-in process, so as to fully The electric heating tube 8 is sprayed with graphite powder, so that the fin connection can be lubricated by the graphite powder. The nanometer size of the graphite powder can also fill in tiny defects and surface unevenness, further enhancing the lubrication effect and protecting the fin connection from wear; through the graphite powder lubrication treatment, a protective film can be formed at the fin connection to prevent oxidation and corrosion of the metal surface and extend the service life of the electric heating tube 8; the one-way delivery valve tube 705 can be conveniently added to the lubricating elastic sleeve 703 to ensure the sufficiency of the graphite powder in the lubricating elastic sleeve 703; at the same time, the fixed hydraulic bag 702 itself continues to expand, so that the outer wall of the plugged electric heating tube 8 can be clamped and fixed by the fixed hydraulic bag 702, which can further ensure the stability of the electric heating tube 8 during installation, thereby ensuring the stability of the electric heating tube 8 during the fin insertion process.

[0041] Working principle: When in use, when the electric heating tube 8 is plugged into the plug-in frame 1, the hydraulic pump 506 is started, and the hydraulic pump 506 can supply liquid to the delivery main pipe 509, and the liquid can be delivered to the clamping delivery conduit 701 through the delivery main pipe 509, so that the liquid can be supplied to the fixed hydraulic bag 702, and when the liquid inside the fixed hydraulic bag 702 increases, the fixed hydraulic bag 702 itself expands, and when the fixed hydraulic bag 702 expands and expands in the assembly pipe groove 706, the fixed hydraulic bag 702 can squeeze the lubricating elastic sleeve 703, and the lubricating elastic sleeve 703 is squeezed, so that the graphite powder in the lubricating elastic sleeve 703 can be sprayed out through the spray hole 704, so that the graphite powder in the lubricating elastic sleeve 703 can be fully sprayed on the outer wall of the electric heating tube 8 during the plug-in process, so that the electric heating tube 8 is fully sprayed with graphite powder during the installation process, so that the fin plug-in can be lubricated by the graphite powder, and the one-way delivery is set The valve tube 705 can conveniently add graphite powder into the lubricating elastic sleeve 703 to ensure the sufficiency of the graphite powder in the lubricating elastic sleeve 703; at the same time, the fixed hydraulic bag 702 can continuously expand itself, so that the outer wall of the plugged electric heating tube 8 can be clamped and fixed by the fixed hydraulic bag 702, which can further ensure the stability of the electric heating tube 8 during installation, thereby ensuring the stability of the electric heating tube 8 during the fin insertion process. When the electric heating tube 8 is plugged in, the locking top column 9 is turned to lock it. The top column 9 is threadedly installed on the plug-in frame 1, and the electric heating tube 8 is pressed against by locking the top column 9 to ensure the stability of the electric heating tube 8 when plugged in. When the fin is inserted into the electric heating tube 8, the plug-in mechanical claw 2 needs to be used in conjunction. When in use, the plug-in mechanical claw 2 can grab the fin to be plugged in. After grabbing the fin, the through hole on the fin is aligned with the electric heating tube 8, thereby driving the plug-in mechanical claw 2 to plug the fin into the appropriate position of the electric heating tube 8;

[0042] When the plug-in mechanical claw 2 inserts the fin to be plugged into the electric heating tube 8, the photoelectric sensor 502 can monitor the moving fin. When the photoelectric sensor 502 detects that a fin passes through, the photoelectric sensor 502 can transmit the monitoring data to the electric cylinder 503 in front of the adjacent position. The symmetrically arranged electric cylinder 503 can be driven to work synchronously. The operation of the electric cylinder 503 can drive the first clamping seat 504 to move. The first clamping seat 504 can drive the second clamping seat 505 and the third clamping seat 601 to clamp the electric heating tube 8 through the adjusting screw 606. In this way, the electric heating tube 8 is clamped by the clamping seat through the simultaneous movement of the fins, which can reduce the fin insertion. The friction vibration generated when the electric heating tube 8 is connected can reduce the aggravation of the friction between the fin and the electric heating tube 8 caused by the vibration, thereby reducing the deformation of the fin itself when plugged in; when the clamping seat is clamped, the hydraulic pump 506 is started, and the hydraulic pump 506 can extract the external hydraulic pipe when working, and the delivery main pipe 509 can be supplied with liquid through the hydraulic pump 506, and the liquid can be delivered to each conduction manifold 507 through the delivery main pipe 509, and the liquid can be introduced into the corresponding hydraulic clamping bag 508 through the conduction manifold 507. The increase of the liquid inside the hydraulic clamping bag 508 can make the hydraulic clamping bag 508 itself expand, and the impulse can be squeezed by the expansion of the hydraulic clamping bag 508, which can further improve the clamping The clamping effect of the holding seat; the hydraulic clamping bag 508 set at the same time can absorb the vibration generated when the fin on the electric heating tube 8 is plugged in through the squeezing contact with the electric heating tube 8, which can further reduce the deviation of the fin caused by the external force during plugging; when the photoelectric sensor 502 set at the same time has been monitoring the presence of the fin, the photoelectric sensor 502 can trigger the electric cylinder 503 in front of the adjacent position to retract, and the first clamping seat 504, the second clamping seat 505 and the third clamping seat 601 connected to the front end of the electric cylinder 503 in front of the adjacent position have the effect of auxiliary positioning. When the fin is plugged in the appropriate position of the electric heating tube 8, the electric cylinder 503 in front of the adjacent position pushes the first clamping seat 504, the second clamping seat 505 and the third clamping seat 601. The second clamping seat 505 and the third clamping seat 601 clamp the electric heating tube 8, and the sizes of the multiple groups of the first clamping seat 504, the second clamping seat 505 and the third clamping seat 601 are the same, so that the plug-in distance between each fin can be guaranteed to be the same; when it is necessary to adjust the plug-in position between the fins, the adjusting screw 606 is turned, and the adjusting screw 606 can be rotated on the first clamping seat 504, so that the second clamping seat 505 and the third clamping seat 601 can be pushed respectively by the upper and lower adjusting screws 606 to adjust the position, so as to change the distance between the first clamping seat 504, the second clamping seat 505 and the third clamping seat 601, so as to adjust the plug-in distance between each fin;

[0043] When the connection of the fin is deformed during the insertion process, the liquid in the hydraulic clamping bag 508 can be injected into the hydraulic cavity 602 through the elastic liquid guide tube 604. The increase of liquid inside the hydraulic cavity 602 can push the fitting top column 607 inside the hydraulic assembly groove 603 to slide. The movement of the fitting top column 607 can drive the extrusion top plate 605 to move. The moving extrusion top plate 605 can press the fins on the adjacent sides tightly. The extrusion effect of the extrusion top plate 605 can reset the deformation generated when the fin and the electric heating tube 8 are inserted and connected. The deformation is reset by the extrusion positioning component 6, which can ensure the close connection between the fin and the electric heating tube 8, which can facilitate the subsequent welding.
