Description

Technical Field

[0001] The present invention relates to the technical field of heat exchanger production, and in particular to automatic cutting equipment for heat exchanger components. Background Art

[0002] Heat exchangers are industrial devices that transfer heat between cold and hot fluids through solid surfaces or direct contact. They are widely used in energy conversion, process control, and waste heat recovery. Heat exchangers can be categorized by structure into tubular (shell-and-tube, coiled tube), plate (flat plate, spiral plate), and specialized (heat pipe, rotary), with shell-and-tube heat exchangers being the most commonly used.

[0003] A search revealed a Chinese invention patent with publication number CN117983883B, which provides automatic cutting equipment for tube bundles in shell-and-tube heat exchangers. The patent comprises an L-shaped base plate, positioned horizontally with its vertical section on the left, and a circular plate disposed on the upper end face of the horizontal section of the L-shaped base plate, which rotates via a rotating shaft. A clamping mechanism is provided on the upper end face of the circular plate, with three clamping mechanisms evenly distributed around the circumference and used to clamp the heat exchange tubes. A base plate is provided on the vertical section of the L-shaped base plate, which slides in the left-right direction via two front-to-back symmetrical moving columns. This invention patent improves efficiency when cutting heat exchange tubes in large quantities.

[0004] However, at present, similar to the above-mentioned patent, most heat exchange tube cutting equipment uses cylinders or electric push rods and other similar components to fix the heat exchange tubes. When cutting heat exchange tubes in large quantities, it is often necessary to clamp multiple heat exchange tubes on a compact device at the same time and cut them in turn. This results in a very complicated distribution of components on the equipment, and it is also inconvenient to wire each component when supplying air or electricity. It is very easy to malfunction in actual production work, affecting production efficiency. In addition, this clamping method is not very applicable and cannot be adjusted according to different specifications of heat exchange tubes. Different equipment is required to cut each specification of heat exchange tube. Summary of the Invention

[0005] In view of the above shortcomings of the prior art, the present invention provides an automatic cutting device for heat exchanger components, which can effectively solve the problem of complicated clamping components when cutting heat exchange tubes in large quantities in the prior art.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions:

A wing platform is provided at one end of the cutting table close to the rotating seat, and a guide plate is provided at the bottom of the wing platform. Both ends of the guide plate are provided with an oblique angle. The oblique angle makes the convex plate gradually pressed down when the pressing assembly rotates to the position of the cutting table, thereby driving the two lifting rods to move downward.

[0009] In the above-mentioned automatic cutting equipment for heat exchanger assemblies, an adjustment assembly corresponding to the position of each group of pressing assemblies is provided at the bottom of the rotating seat. The adjustment assembly includes two fixed plates, and spiral rods are symmetrically rotated and inserted on the two fixed plates. A knob is commonly installed at the opposite ends of the two spiral rods. Threaded sleeves are installed on the two vertical rods, and the two threaded sleeves are respectively threaded with the two spiral rods. When the knob is turned, the two threaded sleeves move symmetrically.

[0010] In the above-mentioned automatic cutting equipment for heat exchanger components, the acute angle formed by the bevel on the guide plate and the horizontal plane does not exceed 45°.

[0011] In the above-mentioned automatic cutting equipment for heat exchanger components, the lower surface of the pressing plate and the bottom of the placement groove are both provided with rubber pads.

[0012] In the above-mentioned automatic cutting equipment for heat exchanger components, a plurality of positioning columns corresponding to the position of each group of pressing components are installed on the upper surface of the rotating seat. The positioning columns are elastically and movably installed, and a control component for simultaneously adjusting each positioning column is installed in the middle of the rotating seat.

[0013] In the above-mentioned automatic cutting equipment for heat exchanger components, a movable groove for the movement of the positioning column is provided on the upper surface of the rotating seat, and the control component includes a mounting seat arranged at the center of the rotating seat, a circular hole is provided inside the mounting seat, and a wedge-shaped plate extending into the circular hole is installed on the side wall of each of the positioning columns, a threaded column is inserted into the top of the mounting seat, the bottom end of the threaded column extends into the circular hole and is installed with a circular plate, and a turntable is installed on the top of the threaded column. When the circular plate moves downward, it presses the wedge plate to cause each positioning column to move outward.

[0014] In the above-mentioned automatic cutting equipment for heat exchanger components, a movable strap is attached to the side of each positioning column close to the wedge plate, and the movable strap is installed in a lifting manner. A movable magnet is installed at the bottom of the movable strap, and a fixed magnet is provided under the rotating seat. When the positioning column rotates to the fixed magnet position, the movable strap and the movable magnet are repelled upward by the fixed magnet.

[0015] In the above-mentioned automatic cutting equipment for heat exchanger components, a T-shaped block is provided at one end of the movable strap close to the positioning column, and a sliding groove adapted to the T-shaped block is vertically opened on the outer wall of the positioning column.

[0017] In the above-mentioned automatic cutting equipment for heat exchanger components, a servo motor for driving the rotating seat to rotate intermittently is provided below the rotating seat, and the servo motor is connected to the electric push rod through an electrical signal.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention fixes the heat exchange tube through a pressing assembly, and automatically controls the pressing assembly with the help of the rotating action of the rotating seat. When the heat exchange tube rotates to the bottom of the cutting machine, the lifting rod is lowered by the cooperation of the guide plate and the convex plate, and the rotating plate enters the lifting rod and becomes vertical. As the lifting rod continues to descend, the pressing plate presses the heat exchange tube to realize the clamping process. Compared with clamping by cylinder, the pressing assembly of the present invention is simpler, does not require wiring and air supply, and is ingenious and convenient.

[0020] 2. The positions of the two movable platforms and vertical rods of the pressing assembly can be changed relatively, which is convenient for adjustment according to heat exchange tubes of different specifications. The convex plate and the synchronous plug-in plate are movably connected without affecting the control of the lifting rod. It is flexible and efficient and can be used for heat exchange tubes of different specifications without changing equipment.

[0021] 3. A movable positioning column is set to adjust the cutting length of the heat exchange tube as needed. All positioning columns can adjust their positions synchronously, which is more convenient to use. When the heat exchange tube is cut and rotated to the fixed magnet, one end of the arc can be automatically lifted, which is convenient for the operator to remove the cut heat exchange tube, thereby improving production efficiency.

DETAILED DESCRIPTION

[0035] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings 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 making any creative efforts shall fall within the scope of protection of the present invention.

[0036] The present invention will be further described below with reference to the embodiments.

[0037] Example: Refer to Figure 1-11 , an automatic cutting device for heat exchanger components, including a rotating seat 1 and a cutting table 3, a cutting machine 6 is installed on the cutting table 3 in a liftable manner, a heat exchange tube is clamped on the rotating seat 1, and the heat exchange tube follows the rotating seat 1 and intermittently rotates to the cutting table 3 position to wait for the cutting machine 6 to descend and be cut. A plurality of sets of pressing components 2 for fixing the heat exchange tube are installed on the rotating seat 1, and the pressing components 2 include two movable tables 201. The rotating seat 1 is provided with a slot for each movable table 201 to move, and the height of the movable table 201 remains unchanged. A vertical rod 202 is provided on the lower surface of the opposite end of the two movable tables 201, and a placement groove 206 is provided on the upper surface of the opposite end of the two movable tables 201. A lifting rod 203 extending to the bottom of the vertical rod 202 is movably inserted on the top of the two movable tables 201. The top of the lifting rod 203 is elastically hinged to the rotating plate 204 through a torsion spring, so that the rotating plate 204 remains as shown in the natural state. Figure 4 As shown in the angle (which can be adjusted according to actual conditions), the top of the rotating plate 204 is vertically connected to the pressing plate 205. When the lifting rod 203 descends, the rotating plate 204 gradually turns into a vertical state and drives the pressing plate 205 to press the heat exchange tube placed in the placement groove 206.

[0038] Reference Figure 4-6The bottom end of one of the lifting rods 203 is connected to a horizontal convex plate 207, and the bottom end of the other lifting rod 203 is connected to a synchronous plug-in plate 208 movably inserted on the side of the convex plate 207. The convex plate 207 and the synchronous plug-in plate 208 are elastically connected to the vertical rod 202. In the natural state, the convex plate 207 and the synchronous plug-in plate 208 are retracted upward to allow the rotating plate 204 to be opened. A wing platform 4 is provided at one end of the cutting table 3 close to the rotating seat 1, and a guide plate 5 is provided at the bottom of the wing platform 4. Both ends of the guide plate 5 are provided with an angle. The angle makes the convex plate 207 gradually pressed down when the pressing assembly 2 rotates to the position of the cutting table 3, thereby driving the two lifting rods 203 to move downward.

[0039] In their natural state, the rotating plate 204 and the pressure plate 205 are open outward, making it easier for the operator to place the heat exchange tube into the placement slot 206. As the rotating base 1 intermittently rotates, the protruding plate 207 reaches the position of the guide plate 5. The protruding plate 207 is constrained by the angle on the guide plate 5 and gradually moves downward, which also drives the synchronous plug plate 208 downward, causing the two lifting rods 203 to descend synchronously. As the lifting rods 203 descend, the rotating plate 204 gradually enters the vertical rod 202. Constrained by the vertical rod 202, the rotating plate 204 becomes vertical and the pressure plate 205 becomes horizontal. As the lifting rod 203 continues to descend, the pressure plate 205 abuts the top of the heat exchange tube and compresses it. When the protruding plate 207 moves completely to the bottom of the guide plate 5, the pressure plate 205 stops descending, and the heat exchange tube is now stably compressed. Therefore, when the heat exchange tube stops under the cutting machine 6, the heat exchange tube is already fixed and ready for cutting. When the cutting machine 6 has cut the heat exchange tube, the rotating seat 1 resumes operation, the convex plate 207 gradually moves to the other end of the guide plate 5, the convex plate 207 gradually returns upward, and the pressing plate 205 also gradually leaves the heat exchange tube, releasing the pressure on the heat exchange tube, making it easier for the operator to remove the cut heat exchange tube.

[0040] Furthermore, to ensure that the pressure plate 205 applies a more precise pressure to the heat exchange tubes, the guide plate 5 can be configured to be liftable. Adjusting the height of the guide plate 5 changes the downward distance of the protruding plate 207, thereby lowering the pressure plate 205 to a more appropriate height and accommodating heat exchange tubes of varying diameters. A specific method for installing the guide plate 5 in a liftable manner is to use a threaded adjustment method, where the top of the guide plate 5 is connected with a bolt, and the height of the guide plate 5 can be adjusted by turning the bolt. Other methods for adjusting the height of the guide plate 5 are also possible and will not be described in detail in this disclosure.

[0041] Reference Figure 6 and Figure 11The bottom of the rotating seat 1 is provided with an adjustment assembly corresponding to the position of each group of pressing components 2. The adjustment assembly includes two fixed plates 17. The two fixed plates 17 are symmetrically rotated and inserted with screw rods 18. The opposite ends of the two screw rods 18 are jointly installed with knobs 19. Threaded sleeves 209 are installed on the two vertical rods 202. The two threaded sleeves 209 are respectively threaded with the two screw rods 18. When the knob 19 is turned, the two threaded sleeves 209 move symmetrically.

[0042] Since the two movable platforms 201 of each set of pressing components 2 are movable, when the knob 19 at the corresponding position is turned, the two screw rods 18 rotate at the same time, and the thread angles of the two screw rods 18 are opposite, so that the two threaded sleeves 209 move in relative or opposite directions, thereby driving the two vertical rods 202 to change positions symmetrically, so as to adjust the distance between the two movable platforms 201, which is convenient for adapting to heat exchange tubes of different specifications, making the device more flexible and having a wide range of applications. When heat exchange tubes of different specifications need to be cut, there is no need to switch equipment, saving equipment expenses.

[0043] Reference Figure 5-6 It should be noted that the acute angle formed between the bevel on the guide plate 5 and the horizontal plane does not exceed 45 degrees. When the protruding plate 207 rotates to the guide plate 5 position, the protruding plate 207 and the guide plate 5 begin to contact. If the bevel angle is too large, the protruding plate 207 will encounter excessive resistance to continued rotation, which will not only affect the normal operation of the rotating base 1, but also increase component wear and affect the stability of the equipment. Therefore, the bevel angle should not be too large, and should be less than 45 degrees to reduce the friction force on the protruding plate 207.

[0044] Reference Figure 4 The lower surface of the pressing plate 205 and the bottom of the placement groove 206 are both provided with rubber pads. The rubber pads not only increase the friction when in contact with the heat exchange tube, improving the stability during pressing, but also provide a certain amount of dimensional reduction, making the pressing plate 205 more suitable for pressing the heat exchange tube.

[0045] Reference Figure 1 and Figure 9 The upper surface of the rotating base 1 is mounted with multiple positioning posts 9 corresponding to the positions of each set of compression assemblies 2. The positioning posts 9 are elastically mounted, and a control assembly is installed in the middle of the rotating base 1 to simultaneously adjust each positioning post 9. The positioning posts 9 serve to locate the cutting position of the heat exchange tube. When placing the heat exchange tube, the inner side of the rounded end of the heat exchange tube can be placed against the positioning post 9. By adjusting the position of the positioning post 9, the extension length of the straight end of the heat exchange tube can be changed, thereby changing the cutting position.

[0046] Reference Figure 10The upper surface of the rotating seat 1 is provided with a movable groove 903 for the positioning column 9 to move. The control component includes a mounting seat 10 arranged at the center of the rotating seat 1. A circular hole is provided inside the mounting seat 10. A wedge plate 15 extending into the circular hole is installed on the side wall of each positioning column 9. A threaded column 13 is inserted at the top of the mounting seat 10. The bottom end of the threaded column 13 extends into the circular hole and is installed with a circular plate 14. A turntable 11 is installed on the top of the threaded column 13. When the circular plate 14 moves down, it presses the wedge plate 15 to move each positioning column 9 outward. When the position of the positioning column 9 needs to be adjusted, the turntable 11 is rotated, and the threaded column 13 will move up or down, thereby driving the circular plate 14 to move up and down. When the circular plate 14 moves down, it will squeeze each wedge plate 15 to make each positioning column 9 move outward synchronously. When the circular plate 14 moves up, each positioning column 9 will be subjected to the elastic reset force to move inward synchronously. In this way, the position of each positioning column 9 can be adjusted synchronously, thereby adjusting the cutting size of the heat exchange tube. It is clever and convenient.

[0047] Reference Figure 9 Each positioning post 9 is attached to the side of the wedge plate 15 near the wedge plate 15. This movable strap 901 is mounted in a liftable manner. A movable magnet 902 is mounted at its base. A fixed magnet 16 is located beneath the rotating base 1. When the positioning post 9 rotates to the position of the fixed magnet 16, the movable strap 901 and the movable magnet 902 are repelled upward by the fixed magnet 16. The fixed magnet 16 is not connected to the rotating base 1 and is mounted via ground-mounted support components. It is positioned at the station following the cutting station (typically the blanking station), where the cut heat exchange tubes are removed.

[0048] When placing the heat exchange tube for loading, the round end of the heat exchange tube presses down the movable strap 901. After the heat exchange tube is cut, it rotates to the position of the fixed magnet 16. The fixed magnet 16 and the movable magnet 902 are set in opposite directions. Therefore, when the heat exchange tube rotates to this position, the movable magnet 902 will be pushed up, thereby driving the movable strap 901 to lift the round end of the heat exchange tube, making it convenient for the operator to remove the cut heat exchange tube, avoiding delays caused by the positioning column 9 when taking out the heat exchange tube, making the operation smoother and avoiding affecting production efficiency.

[0049] A T-shaped block is provided at one end of the movable strap 901 close to the positioning column 9, and a sliding groove adapted to the T-shaped block is vertically opened on the outer wall of the positioning column 9. The movable strap 901 is movably installed by means of the T-shaped block so that it can move up and down without falling off.

[0050] Reference Figure 1-3The cutting table 3 is provided with a discharge port 12 located below the cutter 6, which facilitates the dropping of cut waste to avoid affecting subsequent production. The bottom of the cutter 6 is symmetrically mounted with two slide bars 61. These slide bars 61 extend below the cutting table 3 and are jointly mounted with a connecting plate 62. An electric push rod 7 is mounted on the lower surface of the cutting table 3 to drive the connecting plate 62. The electric push rod 7 drives the connecting plate 62 up and down, which in turn drives the cutter 6 up and down. The cutter 6 is lowered and then raised to form a single cutting action.

[0051] A servo motor 8 is provided below the rotating seat 1 to drive the rotating seat 1 to rotate intermittently. The servo motor 8 is connected to the electric push rod 7 through an electrical signal. The servo motor 8 and the electric push rod 7 are connected through a pulse electrical signal. The servo motor 8 rotates 120 degrees intermittently (in Figure 1 Taking the three pressing assemblies 2 shown as an example), when the servo motor 8 is idle, the electric push rod 7 operates once, driving the cutting machine 6 to first lower and then raise, while the cutting machine 6 continues to operate. This method completes the automatic cutting process of the heat exchange tubes, with high efficiency and a high degree of automation, suitable for large-scale production.

[0052] Working Principle: When cutting heat exchange tubes in large quantities, the equipment is first powered on. Servo motor 8 operates intermittently, driving rotating base 1 to rotate 120 degrees at a time (using the present invention with three sets of compression assemblies as an example; with two sets, the rotation is 180 degrees). At the loading station before the cutting station, the heat exchange tubes are placed on compression assemblies 2 and pulled outward, bringing the rounded ends of the tubes into contact with positioning posts 9. As rotating base 1 intermittently rotates, protruding plate 207 reaches the position of guide plate 5. Constrained by the angle of guide plate 5, protruding plate 207 gradually moves downward, simultaneously driving synchronous insert plate 208 downward, causing the two lifting rods 203 to descend synchronously. When the lifting rod 203 descends, the rotating plate 204 gradually enters the vertical rod 202. Constrained by the vertical rod 202, the rotating plate 204 becomes vertical and the pressing plate 205 becomes horizontal. As the lifting rod 203 continues to descend, the pressing plate 205 sticks to the top of the heat exchange tube and presses the heat exchange tube. When the convex plate 207 is completely moved to the bottom end of the guide plate 5, the pressing plate 205 no longer continues to descend. At this time, the heat exchange tube is also stably pressed and waiting to be cut.

[0053] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
