Abstract
Description
Technical Field
[0001] This utility model relates to the field of cutting equipment technology, and in particular to a round tube cutting mechanism for condensers with a sidewall protection structure. Background Technology
[0002] As a core component of the refrigeration system, the heat exchange efficiency of the condenser is closely related to the machining accuracy of the round tubes. Traditional round tube cutting often uses manual operation or general-purpose cutting equipment, which suffers from problems such as insufficient cut smoothness and large dimensional errors. This can easily lead to a decrease in sealing performance during condenser assembly, affecting system operating efficiency. Although existing automated cutting mechanisms have improved efficiency, they still have problems such as unstable clamping and excessive cutting stress causing tube deformation due to the thin walls and easily deformable characteristics of condenser round tubes. Furthermore, they are difficult to adapt to the rapid switching of round tubes of different specifications, which restricts the needs of large-scale condenser production. Therefore, it is necessary to develop a dedicated cutting mechanism.
[0003] Chinese Patent Publication No. CN220944394U discloses a utility model of a protective round tube cutting machine for condenser production. This utility model relates to the field of condenser production technology and discloses a protective round tube cutting machine for condenser production. It includes a base with four support legs evenly distributed around the base's perimeter. A cutting mechanism is fixedly mounted above the base, and a protective mechanism is fixedly mounted above the cutting mechanism. The protective mechanism includes a protective section and a fixing section, with the front of the protective section and the back of the fixing section fixedly connected. The protective section includes a support column. This protective round tube cutting machine for condenser production, through the protective mechanism and the coordinated operation of a main baffle, side baffles, and back baffle, ensures that when cutting the round tube, flying debris is shielded by the main baffle, side baffles, and back baffle, preventing it from splashing onto surrounding personnel and thus preventing accidents and improving safety.
[0004] Currently, most cutting machines on the market with sidewall protection structures are prone to deformation problems such as dents and excessive ovality when cutting hollow, curved workpieces like round tubes due to uneven force between the protection structure and the tube. This deformation directly damages the structural integrity and dimensional accuracy of the tube, severely affecting the connection effect of subsequent processing steps and the overall quality of the finished product. Furthermore, most cutting processes in the industry still rely on manual operation. However, manual operation is easily affected by differences in operator experience and deviations in judgment of cutting benchmarks. This not only easily leads to errors such as cutting size deviations and uneven cuts, further reducing the consistency of the final product quality, but also poses safety hazards to operators when holding the workpiece close to the high-speed rotating cutting component, such as being cut by flying cutting debris or accidentally touching the cutting edge.
[0005] Therefore, we propose a condenser tube cutting mechanism with a sidewall protection structure to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide a condenser tube cutting mechanism with a sidewall protection structure, which solves the problems in the prior art where the tube is deformed during the cutting process, and the cutting surface is uneven due to human error when the operator is cutting.
[0007] To achieve the above objectives, the present invention adopts the following technical solution: A condenser tube cutting mechanism with a sidewall protection structure includes a base, a housing fixedly connected to the top of the base, a top plate fixedly connected to the top of the housing, an adsorption mechanism on the top of the base, and a cutting mechanism on one side of the adsorption mechanism. The adsorption mechanism includes a fixed frame, the bottom of which is fixedly connected to the top of the base. An adsorption rack is provided on the top of each of the two fixed frames. An air pipe is fixedly connected between the tops of the two adsorption racks. An adsorption chamber is opened inside each of the two adsorption racks. The bottom of the air pipe communicates with the adsorption chamber. A connecting plate is provided on the top of the air pipe. Both ends of the air pipe pass through the connecting plate. A longitudinal hydraulic pump is provided between the connecting plate and the top plate.

[0008] Preferably, a flexible tube is connected to one side of the top of the trachea, an air pump is connected to one end of the flexible tube, a support plate is fixedly connected to the bottom of the air pump, and support columns are fixedly connected to the four corners of the bottom of the support plate. The bottom of all the support columns is fixedly connected to the top plate.
[0009] Preferably, the cutting mechanism includes a cutting tool, and both sides of the cutting tool are rotatably connected to a support frame via a rotating shaft. An extension end of one side of the cutting tool passes through the bottom of the support frame. A drive motor is provided on one side of the cutting tool. The output end of the drive motor is connected to the extension end of one side of the cutting tool via a coupling. A stabilizing frame is fixedly connected between the drive motor and the top plate.
[0010] Preferably, a slider is fixedly connected to the top of each of the two support frames, and two movable slots are opened inside the top plate, which are adapted to the extended ends on both sides of the top of the slider.
[0011] Preferably, a fixing plate is fixedly connected to the bottom of the two sliders, and a horizontal hydraulic pump is fixedly connected to one side of the fixing plate. One end of the horizontal hydraulic pump is fixedly connected to the inner surface of the housing.

[0013] This utility model has at least the following beneficial effects: The device is equipped with a highly adaptable adsorption mechanism. During operation, it uses an air pump to efficiently remove air from the contact surface between the circular tube and the adsorption frame, quickly creating a uniform negative pressure environment inside both. This design effectively counteracts the squeezing and pulling caused by the cutting force during the tube cutting process, preventing deformation and bending of the tube from the source. At the same time, the adsorption force generated by the negative pressure also provides reliable auxiliary fixation for the tube, preventing displacement during the cutting process.
[0014] This utility model also has the following beneficial effects: The device uses an outer shell as its core protection and integrated carrier, completely enclosing the cutting and adsorption mechanisms.

Simultaneously, a movable glass plate is installed on one side of the shell, allowing operators to clearly observe the internal cutting process and easily adjust device parameters. Furthermore, the device's overall structure is simple, reducing initial installation difficulty and facilitating subsequent disassembly and maintenance. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0019] Reference Figure 1-7 A condenser tube cutting mechanism with a sidewall protection structure includes a base 1, which provides stable support and installation foundation for the entire equipment. A shell 2 is fixedly connected to the top of the base 1, which protects the internal components and prevents workers from being injured during the cutting process. A top plate 5 is fixedly connected to the top of the shell 2, which closes the top of the equipment and enhances the structural strength. An adsorption mechanism 3 is provided on the top of the base 1, which can adsorb the tube to prevent deformation during the cutting process and also provide auxiliary fixing. A cutting mechanism 4 is provided on one side of the adsorption mechanism 3 for cutting the tube. The adsorption mechanism 3 includes a fixing frame 301 for supporting and fixing the round tube to be cut. The bottoms of both fixing frames 301 are fixedly connected to the top of the base 1 to ensure the stability of the overall structure. Adsorption frames 302 are provided on the tops of both fixing frames 301. An air pipe 304 is fixedly connected between the tops of the two adsorption frames 302 to transmit airflow. Adsorption chambers 303 are provided inside both adsorption frames 302. A negative pressure is formed between the adsorption chamber 303 and the round tube, thereby adsorbing and fixing the round tube. The pressure generated by adsorption counteracts the stress on the round tube during cutting, preventing deformation and improving product quality. The bottom of the air pipe 304 is connected to the adsorption chamber 302. The air pipe 304 is connected to the top of the top plate 5. The vertical displacement of the air pipe 304 is controlled by the vertical displacement of the connecting plate 305. Both ends of the air pipe 304 pass through the connecting plate 305. A vertical hydraulic pump 308 is installed between the connecting plate 305 and the top plate 5. The vertical hydraulic pump 308 controls the displacement of the connecting plate 305, thereby changing the height of the air pipe 304. This allows the round pipe to pass between the fixing frame 301 and the suction frame 302. The bottom of the vertical hydraulic pump 308 is fixedly connected to the top of the top plate 5, and the top of the vertical hydraulic pump 308 is fixedly connected to the bottom of the connecting plate 305, providing a stable and solid foundation for the operation of the vertical hydraulic pump 308.
[0020] Furthermore, a flexible tube 306 is connected to one side of the top of the trachea 304 for gas transmission between the trachea 304 and the air pump 307. One end of the flexible tube 306 is connected to the air pump 307 to provide a negative pressure power source for adsorption. A support plate 309 is fixedly connected to the bottom of the air pump 307 to stabilize the load-bearing function of the air pump 307. Support columns 310 are fixedly connected to the four corners of the bottom of the support plate 309. The bottom of all the support columns 310 is fixedly connected to the top plate 5 to enhance the stability of the support.
[0021] Furthermore, the cutting mechanism 4 includes a blade 401, which is the core component for realizing the cutting function. Both sides of the blade 401 are rotatably connected to a support frame 402 via a rotating shaft to support the blade 401 and the drive motor 403. An extension end on one side of the blade 401 passes through the bottom of the support frame 402. A drive motor 403 is provided on one side of the blade 401. The output end of the drive motor 403 is connected to the extension end on one side of the blade 401 via a coupling. By starting the drive motor 403, the blade 401 is rotated to cut the target round tube. A stabilizer 404 is fixedly connected between the drive motor 403 and the top plate 5 to fix and stabilize the drive motor 403.
[0022] Furthermore, the tops of the two support frames 402 are fixedly connected to sliders 405. The two sliders 405 respectively share the weight of the tool 401 and the drive motor 403, preventing the tool 401 and the drive motor 403 from falling off during operation due to excessive weight. The top plate 5 has two moving slots 406 inside to restrict the moving direction of the sliders 405. The moving slots 406 are adapted to the extended ends on both sides of the top of the sliders 405.
[0023] Furthermore, a fixing plate 407 is fixedly connected to the bottom of the two sliders 405. The fixing plate 407 enables the two sliders 405 to move synchronously, preventing the tool 401 and the drive motor 403 from being misaligned. A horizontal hydraulic pump 408 is fixedly connected to one side of the fixing plate 407 to provide power for the movement of the two sliders 405. One end of the horizontal hydraulic pump 408 is fixedly connected to the inner surface of the outer shell 2, providing a solid and stable foundation for the operation of the horizontal hydraulic pump 408.
[0024] Specifically, a glass plate 6 is installed on one side of the outer shell 2, through which the working status of the device during the cutting process can be observed. The glass plate 6 extends through one side of the outer shell 2, and a rotating shaft 7 is rotatably connected to the top of the glass plate 6 via a rotating shaft. The rotating shaft 7 extends through the top of the glass plate 6, and both ends of the rotating shaft 7 are fixedly connected to the outer shell 2. This structure allows the glass plate 6 to move and open freely, making it convenient for workers to install or replace the parts inside the device. Feed holes 8 are provided on both sides of the outer shell 2 to facilitate the entry and exit of the round tube.
[0025] In summary: The operator inserts the circular tube into the mounting bracket 301 inside the device through the feed port 8. The longitudinal hydraulic pump 308 is then activated, causing the connecting plate 305 to move, which in turn moves the air pipe 304 longitudinally. This ultimately fixes the adsorption frame 302 to the top of the circular tube, ensuring tight contact between both sides and the mounting bracket 301. Subsequently, the operator activates the air pump 307, which, through the hose 306 and air pipe 304, creates a negative pressure between the adsorption chamber 303 and the outer surface of the circular tube, further assisting in fixing the tube. Simultaneously, the motor 40 is driven. 3. Start rotating the cutter 401. By starting the transverse hydraulic pump 408, the fixed plate 407 is displaced, which in turn causes the slider 405 to move in the moving groove 406, thereby enabling the cutter 401 to cut the round tube. Since the adsorption chamber 303 applies an upward adsorption force to the outer surface of the round tube, it can effectively counteract the stress generated by the cutter 401 during cutting, effectively reduce the deformation of the round tube during the cutting process, and improve the final quality of the product. After the round tube is cut, it can be taken out from the feed hole 8 on one side of the outer shell 2.
