Description

Technical Field

[0001] This utility model relates to the field of fin cutting technology, specifically to a condenser fin cutting device. Background Technology

[0002] A condenser is a component of a refrigeration system, a type of heat exchanger that converts gas or vapor into liquid, rapidly transferring heat from the tubes to the surrounding air. The condenser's operation is exothermic, hence its relatively high temperature.

[0003] Fins are an important component of condensers. The manufactured fins need to be cut to specific lengths to meet the condenser's operational requirements. In related technologies, fins are either cut while stationary or cut by lateral scribing, which affects the cutting efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a condenser fin cutting device to solve the problems existing in the related art.

[0005] To achieve the above objectives, this disclosure provides a condenser fin cutting device, comprising:

[0006] The frame is equipped with a processing position, and the bottom of the fin slides horizontally relative to the processing position;

[0007] A trolley servo motor is fixed to the frame;

[0008] A gearbox is fixed to the frame, and the input shaft of the gearbox is connected to the rotating shaft of the trolley servo motor via a coupling;

[0009] The trolley frame is slidably connected to the machine frame;

[0010] A crank-slider, connected between the trolley frame and the output shaft of the gearbox, is used to drive the trolley frame to slide back and forth; and

[0011] A cutting mechanism, mounted on the trolley frame, is used to cut the fins.

[0012] Optionally, the input shaft and output shaft of the gearbox transmit power using a combination of non-circular gears in the gearbox.

[0013] Optionally, a horizontal slide bar is installed on the frame, and the trolley frame is slidably connected to the horizontal slide bar;

[0014] The crank-slider includes a crank body, a connecting rod, and a slider body. One end of the crank body is fixedly connected to the output shaft of the gearbox, and the other end is hinged to one end of the connecting rod. The other end of the connecting rod is hinged to the slider body. A vertical slide rod is installed on the trolley frame, and the slider is slidably connected to the vertical slide rod.

[0015] Optionally, there are two horizontal slide bars, which are installed on the frame at intervals. One end of the trolley frame is slidably connected to the two horizontal slide bars respectively, and the other end of the trolley frame is equipped with a support wheel. The support wheel is slidably connected to the frame, and both ends of the trolley frame span the conveyor line.

[0016] Optionally, the cutting mechanism includes a flying knife motor, a cam box, a flying knife swing arm, a flying knife connecting rod, a sliding knife holder, and a blade. The flying knife motor is fixed to the frame and connected to the input shaft of the cam box. One end of the flying knife swing arm is fixedly connected to the output shaft of the cam box, and the other end is hinged to one end of the flying knife connecting rod. The other end of the flying knife connecting rod is hinged to the sliding knife holder. The sliding knife holder is slidably connected to the trolley frame, and the blade is mounted on the bottom of the sliding knife holder.

[0017] Optionally, the cutting mechanism further includes a die, through which the blade is connected to the sliding blade holder.

[0018] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects:

[0019] The trolley servo motor drives the crank to rotate via a gearbox, which in turn drives the slider body to slide along the vertical slide bar of the trolley frame via a connecting rod. This propels the trolley frame to reciprocate parallel to the output direction of the conveyor line. The reciprocating motion of the slider body is a variable speed motion process. To ensure optimal cutting effect, the speed of the trolley servo motor must be matched with the output speed of the conveyor line during control, ensuring that the conveyor line speed does not exceed the maximum speed of the trolley frame. In this way, when the slider body's speed is synchronized with the output speed of the aluminum strip during variable speed motion, the cam box is rotated to push out the cutter, making it perpendicular to the fin and cutting it. This ensures the deformation and quality of the cut during cutting, and avoids pipe blockage caused by chip cutting. The fins are cut while relatively stationary, resulting in fins of any set length. Because the machine is not stopped and continuous punching and cutting is performed, the cut quality and production efficiency of the fins are greatly improved. Attached Figure Description

[0025] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0026] In this disclosure, unless otherwise stated, directional terms such as "upper," "lower," "front," "rear," "left," and "right" are used for ease of description based on the drawing orientations of the corresponding figures, while "inner" and "outer" are defined based on the contours of the corresponding components themselves. Terms such as "first" and "second" used in this disclosure are used to distinguish one element from another and do not have sequential or importance implications. Furthermore, when the following description refers to the figures, unless otherwise indicated, the same numbers in different figures represent the same or similar elements.

[0027] Please see Figures 1 to 3 This disclosure provides a condenser fin cutting device, including a frame 1, a trolley servo motor 8, a gearbox 2, a trolley frame 4, a crank-slider, and a cutting mechanism. The frame 1 has a processing position, and the bottom of the fin slides horizontally relative to the processing position. The trolley servo motor 8 is fixed to the frame 1. The gearbox 2 is fixed to the frame 1, and its input shaft is connected to the rotating shaft of the trolley servo motor 8 via a coupling. The trolley frame 4 is slidably connected to the frame 1. The crank-slider is connected between the output shaft of the trolley frame 4 and the gearbox 2, and is used to drive the trolley frame 4 to slide back and forth. The cutting mechanism is mounted on the trolley frame 4 and is used to cut the fins.

[0028] Understandably, the trolley servo motor 8 drives the crank to rotate via the gearbox 2, which in turn drives the slider body 12 to slide along the vertical slide bar of the trolley frame 4 via the connecting rod. This propels the trolley frame 4 to reciprocate parallel to the output direction of the conveyor line. The reciprocating motion of the slider body 12 is a variable speed motion process. To ensure optimal cutting effect, the speed of the trolley servo motor 8 needs to be matched with the output speed of the conveyor line (the movement speed of the fins) during control. This ensures that the conveyor line speed does not exceed the maximum speed of the trolley frame 4. In this way, when the slider body 12 is in variable speed motion and its speed is synchronized with the output speed of the aluminum strip, the cam box 3 is rotated to push out the cutter, making it perpendicular to the fins to cut them. This ensures the deformation and quality of the cut during cutting, and avoids pipe blockage caused by chip cutting. The fins are cut while relatively stationary, resulting in fins of any set length. Because the machine is continuously punched and cut without stopping, the cut quality and production efficiency of the fins are greatly improved.

[0031] In one embodiment, there are two horizontal slide bars 13, which are installed on the frame 1 at intervals. One end of the trolley frame 4 is slidably connected to the two horizontal slide bars 13 respectively, and the other end of the trolley frame 4 is equipped with a support wheel 15, which is slidably connected to the frame 1. Both ends of the trolley frame 4 span the conveyor line.

[0032] In one embodiment, the cutting mechanism includes a flying knife motor 16, a cam box 3, a flying knife swing arm 19, a flying knife connecting rod 20, a sliding knife holder 21, and a blade 22.
