Description

Technical Field

[0001] The invention relates to the technical field of metal pipe cutting, and particularly proposes automatic cutting equipment for waste heat recovery device components. Background Art

[0002] The waste heat recovery device is one of the core equipment in the waste heat recovery system. It is mainly used to capture the waste heat (waste heat) emitted during industrial production and energy utilization, and transfer it to other media (such as water, air, oil, etc.) through heat exchange to achieve heat reuse. The core components of the waste heat recovery device include heat exchangers, heat pipes, waste heat transmission pipes and valves. The heat pipes are made of different metal materials such as stainless steel, copper or aluminum according to the temperature and corrosiveness of the use environment. Among them, copper pipes are the most common heat pipes on the market.

[0003] In the production of waste heat recovery devices, copper tubes need to be cut into the required length. Depending on the wall thickness of the copper tubes, there are many cutting methods. For copper tubes with thicker walls, you can choose to stack multiple copper tubes and cut them at the same time. The cutting process includes four steps: feed, retract, feed and re-feed, which affects the cutting efficiency. Other operations such as polishing are required later, which also affect the production efficiency of the product. For copper tubes with thinner walls, not only the number of simultaneous cuts is greatly reduced, but even more, only one copper tube can be cut at a time. In addition, the "slow feed, steady cutting" cutting method must be selected during cutting, which further reduces the cutting efficiency. If a higher cutting efficiency is to be guaranteed, the product quality of the copper tube itself will also be affected. Summary of the Invention

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 creative efforts are within the scope of protection of the present invention.

[0031] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Figure 1 and Figure 8 Disclosed are two embodiments of an automatic cutting device for a waste heat recovery component, which is used for cutting various pipes inside the waste heat recovery device, including but not limited to copper pipes, stainless steel pipes, and aluminum pipes. Depending on the application environment, the wall thickness of the selected pipes is also different. Thicker pipes are usually selected in high-temperature and high-pressure areas, high-flow rate areas, or areas containing particulate media, while thinner pipes are usually selected in general areas. In scenarios with extremely high requirements for heat transfer efficiency, low medium pressure, and weak corrosiveness, thinner pipes must be selected. Pipes of different thicknesses require different cutting methods.

[0033] As Example 1 of the present invention, Figure 1 It is aimed at cutting thick-walled pipes, including a ring frame 1 with a sleeve ring frame 2 assembled inside. Both the ring frame 1 and the sleeve ring frame 2 are annular. In this embodiment, the surface of the sleeve ring frame 2 is equipped with two sets of saw blade assemblies, which are respectively located directly above and directly below the sleeve ring frame 2. The interior of the ring frame 1 is equipped with a limit assembly for limiting the position of the round pipe, see Figure 4 The saw blade assembly includes a circular cutting saw blade 3 and an external protective cover 4. The limiting assembly includes a limiting tube 13. A group of limiting tubes 13 with a triangular cross-section are assembled on the left and right sides of the ring frame 2. A large number of round tubes are stacked and placed through the limiting tubes 13. The protective cover 4 can rotate around the center of the ring frame 2, driving the cutting saw blade 3 to approach or move away from the round tube. The cutting saw blade 3 itself can rotate to achieve cutting of the round tube.

[0034] The two cutting saw blades 3 in the vertical state rotate close to the two groups of limiting tubes 13 in the horizontal state. The cutting process of the cutting saw blade 3 can be divided into two processes of feeding and retracting. Taking one of the cutting saw blades 3 as the initial position, the cutting saw blade 3 feeds to cut the circular tube inside the first group of limiting tubes 13 on the moving path, and retracts after cutting. The retracting process is the process of the cutting saw blade 3 feeding the circular tube inside the second group of limiting tubes 13 on the moving path. Therefore, if there are more groups of limiting tubes 13, the efficiency of cutting the circular tube will be higher. It should be noted that since the circular tube inside the second group of limiting tubes 13 has been cut by another cutting saw blade 3 when the initial cutting saw blade 3 cuts the circular tube inside the first group of limiting tubes 13, the circular tube needs to be moved immediately after the initial cutting saw blade 3 moves away from the first group of limiting tubes 13 to ensure that the initial cutting saw blade 3 immediately performs a second cutting.

[0035] like Figure 1 and Figure 3As shown, there are three limit tubes 13 in each group, which are respectively located at the front end, middle part and rear end of the ring frame 2. The limit tube 13 at the middle position is assembled on the ring frame 1, and the limit tubes 13 at the front and rear ends are assembled on the ring frame 1 or other fixed positions through fixed seats (the fixed seat to which the rear limit tube 13 is connected is not shown in the figure). It is necessary to ensure that the three limit tubes 13 are at the same height position, and the distance between the limit tube 13 at the front end position and the limit tube 13 at the middle position is the distance that the cutting saw blade 3 can pass through. A feeding assembly is set between the limit tube 13 at the rear end position and the limit tube 13 at the middle position for moving the round tube.

[0036] The feeding assembly includes a slide rail 19 and a mechanical gripper 20 that can move along the slide rail 19. The number of mechanical grippers 20 corresponding to each group of limiting tubes 13 is set to two, which are used to alternately grip the round tube and move. When one of the mechanical grippers 20 is in a gripping state, the other mechanical gripper 20 is in a released state, and the mechanical gripper 20 in the gripping state moves. During cutting, the mechanical gripper 20 in the released state grips the round tube, and the mechanical gripper 20 in the gripping state releases the round tube and moves to the initial position to facilitate subsequent feeding operations. The mechanical gripper 20 has the function of automatically opening and closing to grasp. Its shape is adapted to the shape of the limiting tube 13. In order to ensure the firmness of the mechanical gripper 20 in simultaneously grasping multiple round tubes, an elastic restraint belt 21 is assembled inside it. The two ends of the restraint belt 21 are respectively fixed at the top and bottom positions of the inner side of the mechanical gripper 20. When grasping, the restraint belt 21 wraps the surface of the round tube and firmly squeezes the round tube inside the mechanical gripper 20.

[0037] like Figure 4-Figure 7 As shown, in order to facilitate the rotation and revolution of the cutting saw blade 3, the ring frame 2 is set as a gear ring, and a plurality of equidistant teeth are provided on its surface. The surface of the ring frame 2 is equipped with an arc-shaped mounting frame 12, which is assembled inside the annular frame 1 through a bearing. Four gears 10 meshing with the ring frame 2 are assembled inside the annular frame 1, and are symmetrically arranged on the outside of the ring frame 2 to ensure the stability of the rotation of the ring frame 2. The gear 10 is mounted inside the annular frame 1 through a rotating shaft, and a motor 11 is assembled on the outside of the annular frame 1 to drive any one of the gears 10 to rotate. The surface of the protective cover 4 is provided with a sleeve 6 integrally formed with it, and the surface of the sleeve 6 is provided with a plurality of protruding, integrally formed bar-shaped blocks 7 to limit the protective cover 4 to prevent the sleeve 6 from rotating and avoid affecting the cutting of the circular pipe by the cutting saw blade 3. A slot 8 adapted to the outer shape of the sleeve 6 is provided at the corresponding position of the ring frame 2 to facilitate the installation of the cutting saw blade 3. A thread groove is provided at the tail of the sleeve 6, and the position of the thread groove corresponds to the installation bolt 9.

[0038] The surface of the cutting saw blade 3 is assembled with a round rod that passes through the sleeve 6, and the round rod and the sleeve 6 are installed through a bearing. A motor 5 is assembled on the surface of the ring frame 2 to drive the cutting saw blade 3 to cut the round tube. In the case of cutting multiple round tubes at the same time, one of the cutting saw blades 3 can be replaced with a grinding sheet 15 for grinding. At this time, grinding can be performed while cutting to improve the production efficiency of subsequent round tubes.

[0039] like Figure 1 and Figure 2 As shown, in order to facilitate the grinding of the cut round tube, an L-shaped guide frame 14 is set at the front end of the front limit tube 13, and the front end of the round tube directly rests on the guide frame 14. First, the cutting saw blade 3 moves for cutting, and the cut end is located on the front end limit tube 13 and the guide frame 14. Then the grinding piece 15 moves to the cutting position for grinding, and a base 16 is assembled at the bottom of the guide frame 14. To ensure the stability of the base 16, it can be fixed to the ground or a workbench. A slide groove is provided on the base 16, and a slider adapted to the slide groove is equipped on the guide frame 14. The slider moves inside the slide groove, and the guide frame 14 and the adjacent limit tube 13 are installed and connected by a spring 17.

[0040] When the grinding is completed, the rear round tube squeezes the front cut and polished round tube and moves to squeeze the guide rack 14. When the cut round tube is completely located on the guide rack 14, the position of the guide rack 14 is positioned by external force. The guide rack 14 is set to an inclined surface on the axial side away from the annular rack 1, so that the round tube can slide along the inclined surface of the guide rack 14 surface to reduce the damage to the round tube by gravity. The two sides of the base 16 at the bottom are also set to inclined surfaces to ensure the quality of subsequent products. In order to facilitate the positioning of the guide rack 14, an electromagnetic block 18 is assembled on the surface of the base 16. The guide rack 14 itself has a certain magnetism. The electromagnetic block 18 is energized to adsorb the guide rack 14, thereby loosening the clamping of the round tube. When the round tube slides down, the electromagnetic block 18 is de-energized, and the spring 17 rebounds to pull the guide rack 14 back to its initial position for the next step.

[0041] As embodiment 2 of the present invention, Figure 8 As shown, in the actual cutting production process, the thinner the wall thickness of the round tube is, the fewer the round tubes located inside the same limiting tube 13 will be, and the feed speed will also be reduced. In this embodiment, the limiting tube 13 is set as a pipe with a circular cross-section, and only one cut round tube can pass through the interior of each limiting tube 13. At this time, there are eight limiting tubes 13, and the number of cutting saw blades 3 is also eight. The annular array is on the surface of the ring frame 2, and the installation position of the limiting tube 13 and the cutting saw blade 3 is staggered.

[0042] In this process, multiple round tubes can be cut at the same time. Although the cutting feed speed will slow down, the cutting efficiency will still be improved due to the increase in the number of simultaneous cuttings. The more the number of simultaneous cuttings, the higher the cutting efficiency. Similarly, this cutting method combines the feed step and the retract step into one, effectively reducing the cutting working time, improving the cutting efficiency, and also ensuring the cutting quality of round tubes with thinner wall thickness, indirectly ensuring the subsequent product quality.

[0043] like Figure 9 and Figure 12 As shown, in order to prevent the mechanical gripper 20 from causing depression on the surface of the thin-walled round tube, this embodiment adopts a feeding method different from the feeding assembly of Example 1. In this embodiment, two rotatable conveyor belts 22 are installed on the surface of the annular frame 1 corresponding to the position of each limiting tube 13 (this is the prior art, and the specific structure is not described here). The conveyor belt 22 is installed on the conveyor frame, and the surface of the annular frame 1 is equipped with a fixing frame 24. The fixing frame 24 is equipped with a rotatable double-headed screw 23. The two ends of the double-headed screw 23 are respectively threaded through the two conveyor frames. The distance between the two conveyor belts 22 is adjusted by rotating the double-headed screw 23. The surface of the conveyor belt 22 has a certain viscosity, and it contacts the round tube through viscosity to avoid the depression of the round tube caused by overpressure, so as to realize the transportation of round tubes of different diameters. It should be noted that the conveyor belt 22 needs to be cleaned and replaced regularly. A guide frame 25 is assembled at the rear end of the annular frame 1. The surface of the guide frame 25 is provided with a plurality of limiting grooves 26 with the same inner diameter as the limiting tube 13, and the limiting tube 13 and the limiting grooves 26 at corresponding positions are located at the same height to facilitate feeding.

[0044] like Figure 10-11 As shown, the rotation and revolution of the cutting saw blade 3 are driven in the same manner as in Example 1, and the cutting saw blade 3 can also be replaced when damaged.

[0045] like Figure 8 As shown, when the cut round tube is unloaded, a guide rack 14 is assembled at the front end of the annular rack 1, and two guide grooves 27 are opened on the surface of the guide rack 14. The guide groove 27 is divided into an arc path and an inclined path. When the cut round tube is located inside the guide groove 27, it will first enter the inside of the arc path and slide along the arc path to the inside of the inclined path to buffer the impact caused by gravity. For round tubes of different diameters, a thickened plate can be installed inside the guide groove 27 to reduce the width of the guide groove 27 path and reduce the impact of the round tube during the falling process, so as to ensure the quality of subsequent product production.

[0046] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.
