Description

Technical Field

[0001] This application relates to the field of fin processing equipment, and in particular to a high-efficiency fin cutting equipment. Background Technology

[0002] Fins are metal components attached to the surface of heat exchange devices. They increase the heat transfer efficiency by increasing the heat exchange surface area and are mainly used in scenarios that require enhanced heat exchange, such as boiler economizers and air coolers.

[0003] Chinese Patent CN215786013U discloses a cross-cutting structure for a high-speed fin mold, located behind the fin forming mold. It includes an upper cross-cutting blade and a lower cross-cutting blade. The lower cross-cutting blade is fixedly positioned below the fin's travel path, while the upper cross-cutting blade is floatingly positioned above the fin's travel path. A drive mechanism for controlling the up-and-down movement of the upper cross-cutting blade is also provided. The drive mechanism includes a rotating shaft parallel to the upper cross-cutting blade, an eccentric wheel mounted on the rotating shaft, a connecting rod between the eccentric wheel and the upper cross-cutting blade, and a drive source for controlling the rotation of the rotating shaft.

[0004] During the use of the above technology, because the material belt is conveyed at high speed, when the upper and lower cross-cutting blades are cutting the fins, the material belt will continue to be squeezed towards the upper and lower cross-cutting blades. This will cause the material belt to deform, resulting in lower dimensional accuracy of the finally cut fins and other defects. Utility Model Content

[0005] To address the issue of low dimensional accuracy in fin cutting, this application provides a high-efficiency fin cutting device.

[0006] The high-efficiency fin cutting equipment provided in this application adopts the following technical solution: A high-efficiency fin cutting device includes a fin forming machine. A cutting table is provided at the outlet of the fin forming machine. A clamping frame and a cutting frame are provided on the cutting table. The clamping frame is located between the fin forming machine and the cutting frame. A clamping plate is vertically slidably arranged on the clamping frame. The clamping plate is used to press the fins sliding out of the fin forming machine onto the cutting table. A clamping element is provided on the clamping frame to drive the clamping plate to slide vertically. A cutter is vertically slidably arranged on the cutting frame. A cutting element is provided on the cutting frame to drive the cutter to slide vertically. A detection element is provided on the cutting frame to detect the cutting size of the fins.

[0007] By adopting the above technical solution, when the size of the fins detected by the test piece meets the requirements, the clamping component drives the clamping plate to approach the cutting table until the fins from the discharge end of the fin forming machine are pressed onto the cutting table. Then, the cutting component drives the cutter to slide vertically, thereby accurately cutting the fins and improving the dimensional accuracy of fin processing.

[0008] Optionally, the clamping component includes a clamping guide rail disposed on the clamping frame, the clamping plate being slidably engaged with the clamping guide rail, and a clamping cylinder electrically connected to the control system being disposed on the clamping frame, the clamping plate being disposed on the piston rod of the clamping cylinder.

[0009] By adopting the above technical solution, the control system starts the clamping cylinder, the piston rod of the clamping cylinder extends rapidly, and the piston rod of the clamping cylinder pushes the clamping plate close to the cutting table, thereby pressing the fins onto the cutting table.

[0010] Optionally, a rubber plate may be detachably provided at the bottom of the clamping plate.

[0011] By adopting the above technical solution, during the process of the fins being pressed on the cutting table, the rubber plate will deform and jam the folded fins, so that the fins near the cutter side cannot move. At the same time, the rubber plate effectively reduces the possibility of the fins being squeezed and deformed by the pressing plate.

[0012] Optionally, the cutting component includes a blade mounting plate that is vertically slidably disposed on the cutting frame, the cutting blade being detachably disposed on the blade mounting plate, and a cutting cylinder electrically connected to the control system being disposed on the cutting frame, with the blade mounting plate disposed on the piston rod of the cutting cylinder.

[0013] By adopting the above technical solution, the control system starts the cutting cylinder, the piston rod of the cutting cylinder extends quickly and pushes the cutter close to the cutting table, so that the fins are cut quickly, thereby improving the processing efficiency of the fins.

[0014] Optionally, the detection component includes a material support plate disposed on the cutting table. The material support plate is located on the side of the cutting frame facing away from the clamping frame. An upper scale plate is disposed on the cutting frame above the material support plate, and a lower scale plate is disposed on the cutting table below the material support plate. The upper scale plate and the lower scale plate have the same structure. An oblong hole is formed on the upper scale plate along the direction from the clamping frame to the cutting frame. A signal transmitter is detachably disposed on the oblong hole of the upper scale plate, and a signal receiver is detachably disposed on the oblong hole of the lower scale plate. The signal transmitter and the signal receiver are both electrically connected to the control system. An obstacle clearance groove for signal transmission is formed on the material support plate.

[0015] By adopting the above technical solution, the worker adjusts the distance between the signal transmitter and the cutter on the upper scale plate and the distance between the signal receiver and the cutter on the lower scale plate. When the fins sliding out from the cutting frame block the signal receiver from receiving the signal transmitter, the clamping cylinder and the cutting cylinder respond quickly in sequence, so that the fins are precisely cut.

[0016] Optionally, both the upper and lower scale plates are provided with graduations, and both the signal receiver and the signal transmitter are provided with indicator arrows, which are used to point to the graduations.

[0017] By adopting the above technical solution, on the one hand, it is convenient for workers to adjust the cutting size and length of the fins, and on the other hand, it is convenient to align the positions of the signal transmitter and signal receiver after adjustment.

[0018] Optionally, a collection box is provided next to the cutting table, and a pusher cylinder electrically connected to the control system is provided on the cutting table. The material support plate is located between the pusher cylinder and the collection box, and a pusher plate is provided on the piston rod of the pusher cylinder.

[0019] By adopting the above technical solution, after the fins are cut, the control system activates the pusher cylinder. The piston rod of the pusher cylinder extends quickly, thereby pushing the cut fins into the collection box by the pusher plate. Subsequently, the piston rod of the pusher cylinder drives the pusher plate to quickly reset. This facilitates the transfer of fins and the subsequent continuous cutting process of fins, which helps to improve the processing efficiency of fins.

[0020] Optionally, an inclined guide plate is provided between the material support plate and the collection box, and the guide plate is arranged inclined toward the collection box in a downward direction.

[0021] By adopting the above technical solution, the cut fins can be quickly and smoothly transferred into the collection box, reducing the possibility of the fins slipping out of the collection box.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. After the dimensions of the fins are found to be within the required range, the clamping component drives the clamping plate to approach the cutting table until the fins from the fin forming machine's discharge end are clamped onto the cutting table. Then, the cutting component drives the cutter to slide vertically, thereby accurately cutting the fins and improving the dimensional accuracy of the fin processing. 2. During the process of the fins being pressed on the cutting table, the rubber plate will deform and jam the folded fins, so that the fins near the cutter cannot move. At the same time, the rubber plate effectively reduces the possibility of the fins being squeezed and deformed by the pressing plate. 3. The worker adjusts the distance between the signal transmitter and the cutter on the upper scale plate and the distance between the signal receiver and the cutter on the lower scale plate. When the fins sliding out from the cutting frame block the signal receiver from receiving the signal transmitter, the clamping cylinder and the cutting cylinder respond quickly in sequence, so that the fins are precisely cut.

[0026] The following is in conjunction with the appendix Figures 1-2 This application will be described in further detail.

[0027] This application discloses a high-efficiency fin cutting device.

[0028] Reference Figure 1 A high-efficiency fin cutting device includes a fin forming machine 1, a cutting table 2 is bolted to the outlet of the fin forming machine 1, a pressing frame 3 and a cutting frame 4 are bolted to the cutting table 2, the pressing frame 3 is located between the fin forming machine 1 and the cutting frame 4, and a pressing plate 5 is vertically slidably arranged on the pressing frame 3, the pressing plate 5 is used to press the fins slid out of the fin forming machine 1 onto the cutting table 2.

The clamping component 6 includes a clamping guide rail 61 bolted to the clamping frame 3. The clamping plate 5 is slidably engaged with the clamping guide rail 61. A clamping cylinder 62 electrically connected to the control system is bolted to the clamping frame 3. The clamping plate 5 is bolted to the piston rod of the clamping cylinder 62. A rubber plate 10 is bolted to the bottom of the clamping plate 5.

[0030] Reference Figure 1 and Figure 2 A cutting blade 7 is vertically slidably arranged on the cutting frame 4. A cutting component 8 is arranged on the cutting frame 4 to drive the cutting blade 7 to slide vertically. The cutting component 8 includes a blade mounting plate 81 vertically slidably arranged on the cutting frame 4. The cutting blade 7 is bolted to the blade mounting plate 81. A cutting cylinder 82 electrically connected to the control system is bolted to the cutting frame 4. The blade mounting plate 81 is bolted to the piston rod of the cutting cylinder 82.

[0031] The control system activates the clamping cylinder 62, and the piston rod of the clamping cylinder 62 extends rapidly. The piston rod of the clamping cylinder 62 pushes the clamping plate 5 close to the cutting table 2. The clamping plate 5 drives the rubber plate 10 to slide synchronously until the rubber plate 10 deforms and presses against the fin, so that the fin near the cutter 7 cannot move. Then, the control system activates the cutting cylinder 82, and the piston rod of the cutting cylinder 82 extends rapidly and pushes the cutter 7 close to the cutting table 2, so that the fin is quickly cut off.

[0032] Reference Figure 2 The cutting frame 4 is equipped with a detection element 9, which is used to detect the cutting size of the fins.

[0033] Reference Figure 1 and Figure 2 The testing component 9 includes a material support plate 91 bolted to the cutting table 2. The material support plate 91 is located on the side of the cutting frame 4 facing away from the clamping frame 3. An upper scale plate 92 is bolted to the cutting frame 4 above the material support plate 91, and a lower scale plate 93 is bolted to the cutting table 2 below the material support plate 91. The upper scale plate 92 and the lower scale plate 93 have the same structure. An oblong hole 94 is provided on the upper scale plate 92 along the direction from the clamping frame 3 to the cutting frame 4.

[0034] Reference Figure 1 and Figure 2 A signal transmitter 95 is attached to the oblong hole 94 of the upper scale plate 92, and a signal receiver 96 is attached to the oblong hole 94 of the lower scale plate 93. Both the signal transmitter 95 and the signal receiver 96 are electrically connected to the control system. Both the upper scale plate 92 and the lower scale plate 93 are engraved with scales 11. Both the signal receiver 96 and the signal transmitter 95 are attached with marking arrows 12, which are used to point to the scales 11. The material support plate 91 is provided with a clearance groove 97 for signal transmission.

[0035] Reference Figure 1 and Figure 2 A collection box 13 is arranged next to the cutting table 2. A pusher cylinder 14, which is electrically connected to the control system, is bolted on the cutting table 2. A support plate 91 is located between the pusher cylinder 14 and the collection box 13. A pusher plate 15 is bolted to the piston rod of the pusher cylinder 14. An inclined guide plate 16 is bolted between the support plate 91 and the collection box 13. The guide plate 16 is arranged inclined towards the collection box 13 in a downward direction.

[0036] The worker first determines the processing length of the fin based on the required fin dimensions and adjusts the positions of the signal receiver 96 and signal transmitter 95 using the marked arrow 12. When the fin slides out from the cutting frame 4 and blocks the signal receiver 96 from receiving the signal transmitter 95, the control system controls the clamping cylinder 62 and the cutting cylinder 82 to respond quickly in sequence, thereby quickly cutting the fin.

[0037] After the fins are cut, the control system activates the pusher cylinder 14. The piston rod of the pusher cylinder 14 extends rapidly, causing the pusher plate 15 to quickly push the cut fins into the collection box 13. Subsequently, the piston rod of the clamping cylinder 62 retracts and resets rapidly, the piston rod of the cutting cylinder 82 retracts and resets rapidly, and the piston rod of the pusher cylinder 14 drives the pusher plate 15 to reset rapidly. Subsequent fins continue to be conveyed and the process is repeated, so that the fins are continuously processed.

[0038] The implementation principle of the high-efficiency fin cutting equipment in this application embodiment is as follows: the worker first determines the processing length of the fin by adjusting the position of the signal receiver 96 and the signal transmitter 95 according to the size of the fin to be processed by the marking arrow 12. When the fin slides out from the cutting frame 4 and blocks the signal receiver 96 from receiving the signal transmitter 95, the control system starts the clamping cylinder 62, and the piston rod of the clamping cylinder 62 extends quickly.

[0039] The piston rod of the clamping cylinder 62 pushes the clamping plate 5 close to the cutting table 2. The clamping plate 5 drives the rubber plate 10 to slide synchronously until the rubber plate 10 deforms and presses against the fin, so that the fin near the cutter 7 cannot move. Then, the control system starts the cutting cylinder 82. The piston rod of the cutting cylinder 82 extends quickly and pushes the cutter 7 close to the cutting table 2, so that the fin is quickly cut off.

[0040] After the fins are cut, the control system activates the pusher cylinder 14. The piston rod of the pusher cylinder 14 extends rapidly, causing the pusher plate 15 to quickly push the cut fins into the collection box 13. Subsequently, the piston rod of the clamping cylinder 62 retracts and resets rapidly, the piston rod of the cutting cylinder 82 retracts and resets rapidly, and the piston rod of the pusher cylinder 14 drives the pusher plate 15 to reset rapidly. Subsequent fins continue to be conveyed and the process is repeated, so that the fins are continuously processed.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
