Copper pipe fixed length cutting device for processing car refrigerator fin condenser

Abstract

The application relates to a copper pipe fixed-length cutting device for processing of a fin condenser of a vehicle-mounted refrigerator, and belongs to the technical field of condenser processing. The device comprises a pay-off frame, a copper pipe straightening mechanism and a cutting mechanism which are sequentially connected in communication. A bridging frame and a rolling cutting mechanism are further arranged beside the cutting mechanism. The rolling cutting mechanism comprises a rack, a rolling cutting assembly, a feeding assembly and a fixed-length assembly. The copper pipe is first cut into a relatively long section by the copper pipe straightening mechanism and the cutting mechanism, and then the long copper pipe is divided into small sections by the rolling cutting mechanism, so that small copper pipes are processed. In the process, the feeding roller group in the copper pipe straightening mechanism does not need to frequently stop, so that the load of the motor in the feeding roller group can be reduced, and the service life is prolonged. Meanwhile, the copper pipe divided by the rolling cutting mechanism has a relatively smooth pipe opening, facilitating subsequent flaring processing, and greatly improving the production efficiency.

Description

Technical Field

[0001] This application relates to the technical field of condenser processing, and in particular to a copper tube length-cutting device for processing finned condensers for vehicle refrigerators. Background Technology

[0002] A finned condenser for car refrigerators is a refrigeration component that improves heat dissipation efficiency through a finned structure and is widely used in compressor-type car refrigerators. Its core function is to cool the high-temperature, high-pressure refrigerant vapor discharged from the compressor into a liquid state. Through a combination of copper tubes and aluminum fins, the contact area with air is increased, accelerating heat transfer. It uses copper tubes as the heat-conducting substrate, with aluminum fins (0.1–0.6 mm thick) attached to the outside. An axial fan forces air convection, improving heat dissipation efficiency. Some new designs eliminate the traditional fan, directly attaching the condenser piping to the inner wall of the refrigerator, utilizing the heat-conducting material for heat dissipation, thus reducing size.

[0003] In the production process, copper tubes are first processed into segments of a fixed length using cutting equipment, and then bent. In the existing technology, copper tube straightening mechanism and cutting mechanism are generally used to cut copper tubes to a fixed length. However, since the copper tubes are relatively short, the feeding roller group in the copper tube straightening mechanism needs to stop working every time it is cut, which results in a heavy load on the motor of the feeding roller group. In addition, the ends of the copper tubes processed by the cutting mechanism are not smooth, which affects the subsequent copper tube flaring.

[0004] Therefore, there is an urgent need to develop a fixed-length cutting device with good copper tube cutting effect. Utility Model Content

[0005] The purpose of this application is to provide a copper tube length-cutting device for processing finned condensers of vehicle refrigerators, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides a copper tube length-cutting device for processing finned condensers in vehicle refrigerators, employing the following technical solution: A copper tube length-fixed cutting device for processing finned condensers of vehicle refrigerators includes a winding frame, a copper tube straightening mechanism, and a cutting mechanism connected in sequence. A bridging frame and a rolling cutting mechanism are also provided next to the cutting mechanism. The rolling cutting mechanism includes a frame, a rolling cutting assembly, a feeding assembly, and a length-fixed assembly. The feeding assembly includes a first mounting base, a first servo reduction motor, a rubber roller shaft, and a first cylinder. The first servo reduction motor is fixed on the first mounting base, and the rubber roller shaft is rotatably connected to the first mounting base. The first servo reduction motor is used to drive the rubber roller shaft to rotate. One side of the first mounting base is hinged to the frame. The tailstock of the first cylinder is hinged to the frame, and the piston rod end of the first cylinder is hinged to the first mounting base. A stop roller shaft is provided at the top of the rubber roller shaft, and the stop roller shaft is rotatably connected to the frame. The rolling cutter assembly includes a second mounting base, a drive motor, a rolling cutter, and a second cylinder. The drive motor is fixed on the second mounting base, and the rolling cutter is mounted on the drive motor. One side of the second mounting base is hinged to the frame. The tailstock of the second cylinder is hinged to the frame, and the piston rod end of the second cylinder is hinged to the second mounting base. A support channel is provided on the frame at the bottom of the rolling cutter. The length-fixing component includes a third cylinder and a limiting block. The third cylinder is fixed on the frame and is correspondingly disposed at the end of the support channel. The limiting block is fixed on the piston rod of the third cylinder.

[0007] The top surface of the bridge frame is provided with a V-shaped groove.

[0008] The support channel includes long shafts arranged symmetrically side by side, the long shafts are fixed on the frame, and a number of support bearings are evenly arranged on the surface of the long shafts.

[0009] Preferably, an extension rod is also fixed to the side of the second mounting base, and clamping bearings are symmetrically arranged on both sides of the end of the extension rod, with the clamping bearings located at the top of the support channel.

[0010] By adopting the above technical solution, and by setting an extension rod and a clamping bearing, when the second cylinder pulls the second mounting seat downward, the clamping bearing first presses the copper tube onto the support channel, which facilitates subsequent rolling cutting.

[0011] The cutting mechanism is mounted on the copper tube straightening mechanism, which includes a straightening component and a feeding roller assembly. A second servo reduction motor for driving the feeding roller assembly to rotate is mounted next to the feeding roller assembly.

[0012] In summary, this application includes at least one of the following beneficial technical effects: the copper tube length-cutting device for processing finned condensers of vehicle refrigerators first cuts a longer section of copper tube through a copper tube straightening mechanism and a cutting mechanism, and then cuts the longer section of copper tube into smaller sections through a rolling cutting mechanism. During this process, the feeding roller group in the copper tube straightening mechanism does not need to stop frequently, thereby reducing the load on the motor in the feeding roller group and improving its service life. At the same time, the copper tubes cut by the rolling cutting mechanism have smoother ends, which facilitates subsequent flaring processing and greatly improves production efficiency.

[0017] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0018] This application discloses a copper tube length-cutting device for processing finned condensers in vehicle refrigerators, referring to... Figure 1-3 The system includes a winding rack 1, a copper tube straightening mechanism 2, and a cutting mechanism 3 connected in sequence. The cutting mechanism 3 is mounted on the copper tube straightening mechanism 2. The copper tube straightening mechanism 2 includes a straightening component 21 and a feeding roller group 22. A second servo geared motor 221 for driving the feeding roller group 22 to rotate is installed next to the feeding roller group 22. A bridging frame 4 and a rolling cutting mechanism 5 are also provided next to the cutting mechanism 3. A V-groove is provided on the top surface of the bridging frame 4. The rolling cutting mechanism 5 includes a frame 51, a rolling cutting component 52, a feeding component 53, and a length fixing component 54. The feeding component 53 includes a first mounting base 531 and a first servo geared motor 54. The machine 532, rubber roller shaft 533 and first cylinder 534 are included. The first servo reduction motor 532 is fixed on the first mounting base 531. The rubber roller shaft 533 is rotatably connected to the first mounting base 531 and the first servo reduction motor 532 is used to drive the rubber roller shaft 533 to rotate. One side of the first mounting base 531 is hinged to the machine frame 51. The tailstock of the first cylinder 534 is hinged to the machine frame 51 and the piston rod end of the first cylinder 534 is hinged to the first mounting base 531. A stop roller shaft 535 is provided at the top of the rubber roller shaft 533 and is rotatably connected to the machine frame 51. The rolling cutter assembly 52 includes a second mounting base 521, a drive motor 522, a rolling cutter 523, and a second cylinder 524. The drive motor 522 is fixed on the second mounting base 521, and the rolling cutter 523 is mounted on the drive motor 522. One side of the second mounting base 521 is hinged to the frame 51. The tailstock of the second cylinder 524 is hinged to the frame 51, and the piston rod end of the second cylinder 524 is hinged to the second mounting base 521. A support channel 525 is provided on the frame 51 at the bottom of the rolling cutter 523. The length-fixing component 54 includes a third cylinder 541 and a limiting block 542. The third cylinder 541 is fixed on the frame 51 and is correspondingly disposed at the end of the support channel 525. The limiting block 542 is fixed on the piston rod of the third cylinder 541.

[0019] Reference Figure 3 The support channel 525 includes a long shaft 5251 arranged symmetrically side by side. The long shaft 5251 is fixed on the frame 51. Several support bearings 5252 are evenly arranged on the surface of the long shaft 5251. An extension rod 6 is also fixed on the side of the second mounting base 521. A clamping bearing 61 is symmetrically arranged on both sides of the end of the extension rod 6. The clamping bearing 61 is located at the top of the support channel 525.

[0020] By setting up the extension rod 6 and the clamping bearing 61, when the second cylinder 524 pulls the second mounting base 521 downward, the clamping bearing 61 first presses the copper tube onto the support channel 525 to facilitate subsequent rolling cutting.

[0021] The implementation principle of the copper tube length-cutting device for processing finned condensers of vehicle refrigerators in this application embodiment is as follows: In use, the second servo reduction motor 221 in the feeding roller assembly 22 operates, pulling the copper tube and conveying it to one side of the rolling cutting mechanism 5 via the feeding roller assembly 22. During this process, the copper tube can be straightened by passing through the straightening component 21. After the second servo reduction motor 221 operates a certain number of revolutions according to the set program, it stops conveying the copper tube. The cutting mechanism 3 then cuts the copper tube, at which point a long section of copper tube enters the rolling cutting mechanism 5. The first cylinder 534 in the feeding assembly 53 pushes the first mounting base 531 upward, and the rubber roller shaft 533 pushes the copper tube upward. Between the stop rollers 535 and under the friction of the rubber rollers 533, the copper tube is conveyed forward so that the end of the copper tube abuts against the limit block 542. After that, the first cylinder 534 returns to its original position, the second cylinder 524 shortens and pulls the second mounting base 521 downward. The rolling cutter 523 on the second mounting base 521 cuts the copper tube. After the cutting is completed, the third cylinder 541 shortens and the cut copper tube is automatically unloaded under the action of gravity. The above actions are repeated in sequence. The rolling cutting method can make the end of the copper tube smooth.

[0022] 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.
