Description

Technical Field

[0001] This utility model relates to the field of tube expander technology, and in particular to a component for cleaning tube expander heads. Background Technology

[0002] Hydraulic tube expanders are specialized hydraulic expansion jointing devices used in the manufacturing of heat exchanger tubes and tube sheets for tightening connections. Hydraulic expansion jointing technology offers advantages such as low manufacturing cost, reduced labor intensity, shorter manufacturing cycle, and uniform and reliable expansion joint quality. This technology has been widely applied in heat exchanger manufacturing in petrochemical, power, boiler, nuclear power, and refrigeration industries, improving the quality and production efficiency of domestic heat exchanger equipment.

[0003] During use, hydraulic tube expanders require frequent replacement of the tube expander heads to adapt to different tube expander needs. During use, the tube expander head will rub against the tube wall and become tight. After the tube expander head is tight against the wall, debris and wear will appear on its surface. The debris will enter the gaps between the tube expander heads, making it impossible to close after use. The operator can only use a brush to simply rinse it, which will lead to accelerated wear of the tube expander head and reduce its service life.

[0004] To address this, we designed a component for cleaning tube expansion heads. Utility Model Content

[0005] The purpose of this invention is to provide a component for cleaning tube expansion heads, which addresses the problem that existing technologies cannot properly clean tubes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An assembly for cleaning tube expansion heads includes a base plate, a motor mounted on the base plate, and a rotating shaft mounted on the motor; and further includes:

[0008] The mounting assembly includes a mounting disc on a rotating shaft, several placement holes on the mounting disc, a sealing hole at the bottom of the placement hole, a second thread inside the placement hole, a third fitting ring on the outer wall of the placement hole, and a plugging assembly on the rotating shaft.

[0009] Preferably, the placement disc is fixedly connected to the rotating shaft via a sleeve, the rotating shaft is threadedly connected to the sleeve, and the third fitting ring is fixedly connected to the placement disc.

[0010] Preferably, the blocking assembly includes a wheel mounted on a rotating shaft, a bonding plate mounted on the wheel, a first hollow space symmetrically arranged on the bonding plate, a second hollow space symmetrically arranged on the bonding plate, a plurality of rubber bodies mounted on the bonding plate, a pusher body symmetrically arranged on the bonding plate, and a sealing assembly mounted on the rotating shaft.

[0011] Preferably, the rotating shaft is provided with a first fitting ring, and the first fitting ring is symmetrically provided with extension plates. The first fitting ring is adapted to the rotating shaft, the bottom of the extension plate is fixedly connected to the wheel, and the fitting plate is fixedly connected to the top of the extension plate.

[0012] Preferably, the outer wall of the rotating shaft is provided with a first thread, the first fitting ring is adapted to the first thread, and the rubber body is adapted to the closed hole.

[0013] Preferably, the closure assembly includes a first cover disposed on the extension plate, a second cover disposed on the first cover, a sealing plate disposed on the top of the rotating shaft, a plurality of assist rods disposed on the sealing plate, and a plurality of fitting grooves disposed on the bottom of the sealing plate.

[0014] Preferably, the first cover is fixedly connected to the extension plate, the sealing plate slides on the rotating shaft via the second fitting ring, and the assist rod is fixed to the sealing plate.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This utility model, through the setting of a wheel and a placement plate, allows workers to clean the expansion heads by simply arranging them in sequence in the placement holes and rotating the wheel to make the rubber body on the wheel press against the sealing hole. Then, the sealing plate is pushed in to complete the sealing. The motor is then started to centrifuge and clean the multiple expansion heads, causing the particles and dust mixed inside the expansion heads to be thrown out. Compared with existing brush cleaning, this can effectively improve the service life of the expansion heads. At the same time, after cleaning, the expansion heads only need to be dried, thereby reducing the wear and tear of the expansion heads.

[0017] 2. With the setting of the first thread and the second thread, when the operator installs the expansion head on the mounting plate, the expansion head can be fixed by the second thread, which prevents the expansion head from being thrown out during the rotation of the shaft, thereby improving the cleaning efficiency of the expansion head. The wheel connects with the mounting plate through the first thread, so that the bottom of the expansion head is in a closed state, reducing the leakage of cleaning fluid from this point, thereby improving the cleaning efficiency of the cleaning fluid.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1-5 An assembly for cleaning tube expander heads includes a base plate 1, a motor 2 mounted on the base plate 1, and a rotating shaft 201 mounted on the motor 2. The assembly is characterized by further including a mounting component, which is mainly mounted on the rotating shaft 201 and is used to mount tube expander heads replaced by the tube expander. The tube expander heads are components used in existing tube expander machines for tube expansion and are typically placed around the tube expander. They are susceptible to adhesion from the environment and particles and dust generated during tube expansion, which can prevent the tube expander heads from being reassembled and affect their use.

[0026] The base plate 1 is an existing flat surface, which is used for leveling various tools. Before cleaning the expansion tube head, it is necessary to check whether the motor 2 and the rotating shaft 201 can be used normally, and whether the output end of the rotating shaft 201 and the motor 2 are fixedly connected by fasteners. If there is any looseness, it needs to be tightened again with tools. Using fasteners makes it easier for workers to disassemble and replace later. Then, install the mounting component on the rotating shaft 201, place the rated number of expansion tube heads inside, add an appropriate amount of cleaning fluid, and start the motor 2 to make the rotating shaft 201 rotate to clean the expansion tube head.

[0027] It should be noted that the cleaning fluid is a common cleaning fluid used for metal parts in the prior art. It can effectively remove rust and dust from the surface of metal parts and improve the lubrication and shine of the metal parts surface.

[0028] Specifically, the mounting components are mounted on the mounting plate 4 on the rotating shaft 201, a plurality of mounting holes 401 mounted on the mounting plate 4, a sealing hole 402 mounted at the bottom of the mounting hole 401, a second thread 403 mounted inside the mounting hole 401, a third fitting ring 404 mounted on the outer wall of the mounting hole 401, and a blocking component mounted on the rotating shaft 201.

[0029] The mounting plate 4 is fixedly connected to the rotating shaft 201 through the sleeve 205, the rotating shaft 201 is threadedly connected to the sleeve 205, and the third fitting ring 404 is fixedly connected to the mounting plate 4.

[0030] When installing the expansion head, the threads on the outer wall of the expansion head need to be cleaned. Then, align the second thread 403 on the inner wall of the placement hole 401 and install the expansion head into the placement hole 401 by rotation. The expansion head will then block the sealing hole 402 and also press against the third contact ring 404. The third contact ring 404 can increase the friction of the expansion head, thereby reducing the phenomenon of falling off and resetting during the cleaning process. The placement plate 4 is fixedly connected to the sleeve 205 by welding. The sleeve 205 is connected to the rotating shaft 201 by threads and then fixed at both ends by welding to ensure that the placement plate 4 and the rotating shaft 201 will not rotate on their own. The third contact ring 404 is fixed to the placement plate 4 by welding, which can effectively increase the friction of the outer wall of the expansion head, thereby reducing the expansion head from being thrown out by centrifugal force.

[0031] The blocking assembly includes a wheel 3 mounted on a rotating shaft 201, a bonding plate 301 mounted on the wheel 3, a first cutout 302 symmetrically mounted on the bonding plate 301, a second cutout 303 symmetrically mounted on the bonding plate 301, several rubber bodies 304 mounted on the bonding plate 301, a pusher body 305 symmetrically mounted on the bonding plate 301, and a sealing assembly mounted on the rotating shaft 201.

[0032] A first fitting ring 202 is provided on the rotating shaft 201, and an extension plate 203 is symmetrically provided on the first fitting ring 202. The first fitting ring 202 is adapted to the rotating shaft 201, the bottom of the extension plate 203 is fixedly connected to the wheel 3, and the fitting plate 301 is fixedly connected to the top of the extension plate 203.

[0033] The outer wall of the rotating shaft 201 is provided with a first thread 204, the first fitting ring 202 is adapted to the first thread 204, and the rubber body 304 is adapted to the closed hole 402.

[0034] After all the expansion heads are installed, the staff can touch the pusher 305 to make the wheel 3 rotate on the first thread 204 and rotate it to the tightening stage. At this time, the rubber body 304 on the wheel 3 will press against the sealing hole 402, thereby blocking the bottom of the expansion head and preventing the cleaning fluid from leaking from here and affecting the cleaning efficiency.

[0035] The first thread 204 is located between the wheel 3 and the mounting plate 4. When the wheel 3 is not connected to the first thread 204, it is suspended on the rotating shaft 201. At this time, it contacts the rotating shaft 201 through the first fitting ring 202. When the rotating shaft 201 rotates, it does not move in conjunction with the first fitting ring 202. The first fitting ring 202 is connected to the fitting plate 301 by welding. The rubber body 304 needs to be fixed to the fitting plate 301 by fasteners. The rubber body 304 is made of relatively soft rubber, which can improve the fault tolerance rate.

[0036] After the expansion head is cleaned, the turntable 3 is rotated to disengage the rubber body 304 from the closed hole 402. The first bonding ring 202, while not completely disengaged from the first thread 204, rotates several rubber bodies 304 to the bottom of the placement plate 4. A sliding groove is provided between each closed hole 402 to accommodate the rubber body 304. After completing the above steps, the first cutout 302 and the second cutout 303 on the bonding plate 301 will be perpendicular to the bottom of the closed hole 402. At this time, cleaning fluid will be discharged from the closed hole 402. The motor 2 can be run at low power to cooperate with the rotating shaft 201 to discharge the expansion head and the internal cleaning fluid, thereby improving the cleaning effect of the expansion head.

[0037] The sealing assembly includes a first cover 206 disposed on the extension plate 203, a second cover 207 disposed on the first cover 206, a sealing plate 5 disposed on the top of the rotating shaft 201, a plurality of assist rods 501 disposed on the sealing plate 5, and a plurality of fitting grooves 502 disposed on the bottom of the sealing plate 5.

[0038] The first cover 206 is fixedly connected to the extension plate 203, the sealing plate 5 slides on the rotating shaft 201 through the second fitting ring 208, and the assist rod 501 is fixed to the sealing plate 5;

[0039] Before cleaning the tube expansion head, the sealing plate 5 needs to be pushed in. The operator needs to contact the assist rod 501 to push the sealing plate 5 inward through the rotating shaft 201. The second fitting ring 208 at the top of the sealing plate 5 can be raised to form a closed structure of the rotating shaft 201 to prevent the sealing plate 5 from being detached by centrifugal force during rotation. At the same time, a rubber ring can be set on the outer wall of the sealing plate 5 to increase the friction between the sealing plate 5 and the second cover 207 and reduce the phenomenon of being thrown out and reset. During the process of pushing the sealing plate 5, it is necessary to ensure that the fitting groove 502 is pressed tightly against the tube expansion head to ensure the adhesion effect of the cleaning fluid and reduce the splashing of the cleaning fluid, thereby improving the cleaning efficiency of the tube expansion head.

[0040] The working principle of this utility model is as follows:

[0041] When cleaning the tube expander head of the tube expander is required, simply connect the thread at the bottom of the tube expander head to the second thread 403, and secure it in the placement hole 401 and the sealing hole 402. Then, rotate the wheel 3 to connect the first contact ring 202 to the first thread 204, and the rubber body 304 on the contact plate 301 will seal the sealing hole 402. Put an appropriate amount of cleaning fluid inside, and then push the sealing plate 5 to press the contact groove 502 against the top of the tube expander head. Then, start the motor 2. The rotating shaft 201 will drive the wheel 3, the placement plate 4, and the sealing plate 5 to rotate simultaneously. The cleaning fluid cleans the tube expander head under the effect of rotation. After cleaning the tube head, turn off motor 2 and rotate wheel 3 to half thread of the first thread 204. At this time, rubber body 304 will disengage from closed hole 402. Wheel 3 can be finely adjusted again to make rubber body 304 press against the slide groove. Align the first hollow 302 and the second hollow 303 with closed hole 402. At this time, cleaning fluid will flow out from closed hole 402. Motor 2 can also be started to run at low power. The rotation will increase the discharge efficiency of cleaning fluid. At the same time, the debris cleaned out can also be collected by the first hollow 302 and the second hollow 303. The rotation will also increase the drying efficiency of the tube head. With the setting of the wheel 3 and the placement plate 4, when the staff needs to clean the expansion tube heads, they only need to arrange them in the placement hole 401 in sequence and rotate the wheel 3 so that the rubber body 304 on the wheel 3 is pressed against the sealing hole 402. Then, the sealing plate 5 is pushed in to complete the sealing. Then, the motor 2 is started to centrifuge and clean multiple expansion tube heads, so that the particles and dust mixed in the expansion tube heads are thrown out. Compared with the existing brush cleaning, it can effectively improve the service life of the expansion tube heads. At the same time, after cleaning, the expansion tube heads only need to be dried, thereby reducing the wear and tear of the expansion tube heads.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
