Description

Technical Field

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

[0002] An evaporator is an object that converts liquid substances into gaseous substances. There are a large number of evaporators in industry. Evaporators require a lot of heat dissipation tubes during the production process. During production, the heat dissipation tubes need to be cut. Common cutting devices require manual pulling of the heat dissipation tubes, which is inefficient and the cutting length is not easy to control.

[0003] An existing authorized patent describes a cutting device for evaporator production, patent number CN202320712725.8. This device selects a suitable limiting frame based on the outer diameter of the evaporator heat dissipation tube and fixes it with mounting blocks. Then, a roller controlled by a motor at the initial end of a guide groove pulls the heat dissipation tube, causing one end to pass through the limiting frame. At this point, a drive motor controls the horizontal distance between the baffle and the cutting blade according to the required cutting length. The baffle on one end of the pulled heat dissipation tube contacts the cutting blade, driving a hydraulic cylinder and a second motor to control the cutting blade to cut the heat dissipation tube below. The cut tube segments are collected through a discharge channel. This automatic traction cutting device improves the production efficiency of evaporator heat dissipation tubes.

[0004] The above-mentioned utility model only limits the evaporator heat dissipation tube during the cutting process by using a limiting frame, which still easily leads to the movement of the evaporator heat dissipation tube during cutting. In addition, the bottom of the evaporator heat dissipation tube to be cut lacks support during cutting, which easily leads to uneven cuts.

[0005] Therefore, we have made improvements to this and proposed a cutting-off device for evaporator production. Utility Model Content

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] Example: Figures 1 to 3 As shown, this utility model discloses a cutting device for evaporator production, comprising a base 1 and a base 2. A placement frame 3 is placed between the base 1 and the base 2, and the base 1 and the base 2 are connected by a fixing plate 20. The top surface of the placement frame 3 is open, and one side of the placement frame 3 is magnetically connected to the fixing plate 20. The cut evaporator heat dissipation pipe 4 can be temporarily placed in the placement frame 3, and the fixing plate 20 serves as a connection.

[0025] The top surface of the base 1 has a placement groove 5, in which the evaporator heat dissipation tube 4 is placed. Threaded rods 8 are rotatably installed on both sides of the base 1. Slider 9 is threadedly connected to the two threaded rods 8, and a push plate 6 is provided on both sliders 9. The push plate 6 contacts one side of the evaporator heat dissipation tube 4. The push plate 6 can be moved by rotating the threaded rods 8. When the push plate 6 moves, it pushes the evaporator heat dissipation tube 4 to move, which facilitates the cutting of the evaporator heat dissipation tube 4.

[0026] A mounting bracket 10 is fixedly installed on the top surface of the base 1. Electric push rod 2 17 and electric push rod 3 18 are respectively installed on the top surface of the mounting bracket 10. A limit plate 16 is fixedly connected to the telescopic end of electric push rod 2 17, and a drive motor is fixedly connected to the telescopic end of electric push rod 3 18. A cutting blade 19 is fixedly connected to the output end of the drive motor. During the movement of the evaporator heat pipe 4, the limit plate 16 moves downward under the action of electric push rod 2 17 but does not contact the evaporator heat pipe 4. When it is necessary to cut the evaporator heat pipe 4, the limit plate 16 contacts the evaporator heat pipe 4, but the evaporator heat pipe 4 can rotate. Under the action of electric push rod 3 18, the drive motor and cutting blade 19 can move downward to a specific position. The drive motor drives the cutting blade 19 to rotate, cutting the evaporator heat pipe 4. During cutting, the evaporator heat pipe 4 rotates, making it easier to cut. During the cutting process, electric push rod 3 18 slowly drives the drive motor and cutting blade 19 downward.

[0027] An electric push rod 13 is fixedly installed on one side of the base 2. The telescopic end of the electric push rod 13 is fixedly connected to a support frame 11. A motor 12 is fixedly installed on the inner wall of the support frame 11. The output end of the motor 12 is fixedly connected to a locking block 15 via a rotating shaft, and the locking block 15 is engaged inside the evaporator heat dissipation tube 4. The top surface of the support frame 11 is arc-shaped. The electric push rod 13 can drive the support frame 11 to move, thereby supporting the evaporator heat dissipation tube 4, which facilitates stability during cutting and prevents uneven cuts. When the support frame 11 moves, it will drive the motor 12 and the locking block 15 to move together until the locking block 15 is engaged inside the evaporator heat dissipation tube 4. The motor 12 is a geared motor. When the motor 12 rotates, it can drive the evaporator heat dissipation tube 4 to rotate through the locking block 15, which facilitates cutting.

[0028] The base 1 has symmetrical mounting slots on both sides, and the threaded rod 8 is rotatably mounted in the mounting slots. The motor 7 is symmetrically mounted on one side of the base 1, and one end of the threaded rod 8 rotatably passes through the base 1 and is fixedly connected to the output end of the motor 7. The motor 7 is a reversible motor. When it is working, it can drive the threaded rod 8 to rotate, which allows the slider 9 to drive the push plate 6 to move. The push plate 6 pushes the evaporator heat dissipation tube 4 to move.

[0029] The bottom end of the limiting plate 16 is arc-shaped, and the limiting plate 16 is attached to the surface of the evaporator heat dissipation pipe 4, so that it can play a certain limiting role during cutting.

[0030] A connecting plate 14 is fixedly installed on the bottom surface of the support frame 11. The two sides of the connecting plate 14 extend downward and are slidably connected to the placement frame 3 and the base 2. When the support frame 11 moves, it can move along the placement frame 3 and the base 2, thereby playing a guiding role.

[0031] The top and one side of the support frame 11 are open, and the surface of the locking block 15 is covered with a rubber pad, which makes it easy to rotate the evaporator heat dissipation tube 4. After the cutting is completed, the electric push rod 13 drives the support frame 11 to move away from the cutting blade 19, so that the top of the placement frame 3 is open. Then the cut evaporator heat dissipation tube 4 can be removed manually and placed in the placement frame 3, and then the next section of cutting can be continued.

[0032] A controller is fixedly installed on one side of the base 1. Motor 1 7, Motor 2 12, drive motor, electric push rod 1 13, electric push rod 2 17, and electric push rod 3 18 are all electrically connected to the controller. The controller model is SC200. The controller can control the start and stop of motor 1 7, motor 2 12, drive motor, electric push rod 1 13, electric push rod 2 17, and electric push rod 3 18 respectively, so as to better position and cut the evaporator heat dissipation tube 4.

[0033] During operation, before cutting the evaporator heat dissipation tube 4, the electric push rod 17 drives the limiting plate 16 to fix the evaporator heat dissipation tube 4, and the electric push rod 13 drives the support frame 11 to support the evaporator heat dissipation tube 4 to be cut. At the same time, the locking block 15 is locked inside the evaporator heat dissipation tube 4, which can drive it to rotate, so that the cutting blade 19 can cut it.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
