Description

Technical Field

[0001] This utility model relates to the field of cutting machines for producing tubular heat exchangers, and more particularly to a cutting device for producing tubular heat exchangers. Background Technology

[0002] Tubular heat exchangers consist of a shell and tube bundles. Cold and hot fluids exchange heat through the tube walls. As a traditional standard heat exchange device, tube cutting is one of the key processes in the production of tubular heat exchangers. The cutting accuracy, efficiency and tube end quality directly affect the reliability of subsequent expansion and welding processes, and ultimately determine the heat exchanger's sealing performance, pressure resistance and service life.

[0003] A search revealed Chinese Patent Publication No. CN220498480U, which discloses a cutting device for producing tubular heat exchangers. The device includes a processing table, an adjustment mechanism, and a cutting mechanism, with the cutting mechanism positioned above the adjustment mechanism. The adjustment mechanism comprises an adjustment section and a clamping section, with the adjustment section located below the clamping section. The clamping section can clamp and fix heat exchanger tubes of different diameters via the adjustment mechanism, while the adjustment section facilitates the movement of the heat exchanger tubes. Only one side of the heat exchanger tube needs to be disassembled or reassembled to move its position, avoiding simultaneous disassembly and reassembly of both sides, thus improving the cutting efficiency and increasing the production efficiency and application range of the cutting device for tubular heat exchangers. The cutting mechanism facilitates the cutting of the heat exchanger tubes, and the protective outer shell protects the tubes during cutting, enhancing the safety of the cutting device during tubular heat exchanger production.

[0004] While the aforementioned technologies have increased the production efficiency of the cutting device for tubular heat exchangers, the debris generated during the cutting process falls downwards onto the inner wall of the cavity structure inside the equipment. Due to the narrow space, cleaning is inconvenient and there are blind spots, increasing the workload of operators and causing production interruptions due to machine downtime for cleaning. At the same time, some debris adheres to the outer wall of the threaded rod and enters the thread gap as the equipment runs, causing thread wear, jamming, or even breakage, significantly shortening the service life of the equipment and increasing maintenance costs. Therefore, a cutting device for tubular heat exchanger production is proposed to solve the above problems. Utility Model Content

[0031] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a cutting device for producing tubular heat exchangers, comprising a processing table 1, a clamping component 4, and a cutting component 2. Support legs are fixedly connected to the four corners of the bottom of the processing table 1 to support it and provide space for the collection frame 74 to be installed. The clamping component 4 includes a C-shaped clamping plate with its opening facing forward. A cylinder is fixedly installed at the top of the C-shaped clamping plate, and the output shaft of the cylinder passes through the upper part of the C-shaped clamping plate. An upper clamping plate and a lower clamping plate are provided inside the C-shaped clamping plate. The top of the plate is fixedly connected to the bottom of the output shaft of cylinder 1 and driven by cylinder 1. The lower clamping plate is fixedly connected to the bottom of the inner wall of the C-shaped clamping plate and can support the outer wall of the tube heat exchanger. The cutting component 2 includes a cutting machine and cylinder 2. The output shaft of cylinder 2 passes through the front of the L-shaped plate 3 and is fixedly connected to the mounting plate. The cutting machine is installed on the lower part of the mounting plate. The heat exchange tube can be stably clamped by the clamping component 4. The heat exchange tube can be cut by the cutting component 2. The upper part of the processing table 1 is equipped with a cleaning component 7.

[0032] Furthermore, the cleaning component 7 includes a through groove 71, through which processing debris can fall downwards into the collection frame 74. The through groove 71 is located in the middle of the processing table 1 near the front. The left and right inner walls of the through groove 71 are fixedly connected to positioning rods 73 for supporting the guide frame 76 and stabilizing its left and right movement. The outer wall of the positioning rods 73 is slidably connected to the guide frame 76, which is driven by the servo motor 5 and the screw 2 to move the clamping component 4. The middle of the processing table 1, near the top of the rear surface inner wall of the through groove 71, has a slide groove 72 that provides rear sliding space for the guide frame 76. The rear surface inner wall of the processing table 1, near the slide groove 72, has a slide groove 78 that provides stable sliding for the screw 2 and the guide block 77. The rear end of the guide frame 76 is fixedly connected to a guide block 77 that drives the guide frame 76 to move. The guide block 77 is slidably connected to the inner wall of the slide groove 78. The guide block 77 is driven and connected to the servo motor 5 through the threaded screw 2. The servo motor 5 is fixedly installed on the left side of the machining table 1 near the rear. The threaded screw 2 is set on the inner wall of the slide groove 78 and its two ends are rotatably connected to the machining table 1. The left end of the threaded screw 2 passes through the machining table 1 and is fixedly connected to the right side of the output shaft of the servo motor 5. The rear part of the guide frame 76 is slidably connected to the inner wall of the slide groove 72. The bottom end of the machining table 1 is slidably inserted with a collection frame 74 to collect the debris that falls during processing. The front surface of the machining table 1 is rotatably connected with a latch 75 that can limit the installation of the collection frame 74. The bottom end of the machining table 1 is fixedly connected with two sets of L-shaped blocks. The collection frame 74 is inserted between the two sets of L-shaped blocks.

The collection frame 74 is located at the bottom of the processing table 1 below the through groove 71. The latch 75 is a combination of a cylinder with a long bottom and a short top, plus a disc. The disc is rotatably connected to the middle of the front surface of the processing table 1. The long cylinder at the bottom is set at the bottom due to gravity. The long cylinder at the bottom presses against the front surface of the collection frame 74, which can limit the collection frame 74. When it needs to be removed, the locking buckle 75 can be rotated to release the limit of the collection frame 74. There are two sets of clamping components 4. One set is fixedly connected to the top of the guide frame 76, and the other set is fixedly connected to the upper surface of the processing table 1 near the right side. The clamping component 4 near the right side is fixed and the clamping component 4 on the left side can move with the guide frame 76. The cutting component 2 is set at the upper front end of the L-shaped plate 3. The cutting component 2 is supported by the L-shaped plate 3. The clamping component 4 is used to stably clamp the processed pipe, and the cutting component 2 is used to cut the stably clamped processed pipe.

[0034] Reference Figure 1 , Figure 2 and Figure 4An adjustment assembly 6 is located near the rear surface of the processing table 1. The adjustment assembly 6 includes a second servo motor 61, a first threaded screw 65, a slider 63, and a third slide groove 67. The second servo motor 61 drives the first threaded screw 65 to rotate. The rotation of the first threaded screw 65 is threadedly connected to the moving block 64, driving the moving block 64 and the L-shaped plate 3 to move, thereby moving the cutting component 2 left and right. The slider 63 and the third slide groove 67 are designed in a dovetail rectangular shape to ensure stable movement of the L-shaped plate 3 and the cutting component 2. The second servo motor 61 is fixedly installed on the upper surface of the processing table 1 near the right rear side. The right end of the first threaded screw 65 is fixedly connected to the left end of the output shaft of the second servo motor 61. Two... Two sets of fixing blocks 66 are fixedly connected to the left side and the right side of the servo motor 61, respectively. A threaded screw 65 passes through the right fixing block 66 and is rotatably connected to the middle right side of the left fixing block 66. The threaded screw 65 is supported by the two sets of fixing blocks 66. A slider 63 is fixedly connected to the bottom end of the L-shaped plate 3 and is slidably connected to the inner wall of the slide groove 67. A moving block 64 that drives the L-shaped plate 3 to move is fixedly connected to the rear surface of the L-shaped plate 3 near the top of the slider 63. The threaded screw 65 passes through the moving block 64 and is threadedly connected to its middle part. The moving block 64 slides on the upper surface of the processing table 1. A baffle 62 for blocking debris is fixedly connected to the upper surface of the processing table 1 near the front of the L-shaped plate 3.

[0035] Working principle: When in use, first connect the power supply and switch of the electrical equipment in this device. Place the processing pipe on the lower clamping plate, and then start the cylinder one to make its output shaft drive the upper clamping plate to move downward to clamp and fix the processing pipe. With the help of the two sets of clamping components 4, the processing pipe can be stably fixed. At this time, start the cutting machine on the cutting component 2 and start the cylinder two to make its output shaft drive the cutting machine to move downward to cut the pipe.

[0036] When the cutting position needs to be adjusted, the servo motor 61 can be started, and its output shaft can drive the threaded screw 65 to rotate. The threaded screw 65 is threadedly connected to the moving block 64, which drives the moving block 64 to move horizontally. The moving block 64 drives the L-shaped plate 3 to move, which in turn drives the cutting component 2 to move. The cutting position can be adjusted without adjusting the position of the processed pipe, thus improving processing efficiency and flexibility.

[0037] During the cutting process, the generated debris falls downwards through the through groove 71 into the collection frame 74. When it is necessary to clean the collection frame 74, the locking buckle 75 can be rotated so that the bottom cylinder rotates to the left horizontal position, releasing the contact and compression with the collection frame 74. Then, the handle on the collection frame 74 can be pulled outwards to move the collection frame 74 outwards, making it easy to remove the collection frame 74 for cleaning and emptying the collected debris. This improves cleaning efficiency and convenience. After cleaning, the collection frame 74 can be reinstalled into the bottom of the processing table 1 to continue collecting debris.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
