Description

Technical Field

[0001] The present invention mainly relates to the technical field of air conditioner accessory processing, and particularly relates to a punching processing device and punching process for an air conditioner condenser manifold. Background Art

[0002] After the high-temperature gas refrigerant discharged from the compressor of the air conditioner enters the condenser, in order to improve the heat dissipation effect and reduce the pipe resistance of the pipeline, it is designed to have multiple shunts for cooling and heat dissipation. Each shunt refrigerant will finally enter the manifold. The main function of the manifold is to collect the high-temperature gas refrigerant in the condenser and transfer it; the manifold and the condenser are mostly connected by welding. When the manifold is produced, multiple round grooves need to be stamped on the pipe material so that the pipelines on the condenser can be installed on the manifold.

[0003] When punching the pipe, the pipe is prone to deformation around the punching position due to the relatively large punching force, which will affect the use of the air conditioner condenser manifold. Summary of the Invention

[0004] The present invention mainly provides a punching processing device and punching process for an air conditioner condenser manifold to solve the technical problems mentioned in the above background art.

[0005] The technical solution adopted by the present invention to solve the above technical problems is as follows:

[0006] A punching processing device for an air conditioner condenser manifold includes a bottom plate. Two support columns are arranged on the top of the bottom plate, and a displacement mechanism for adjusting the distance between the two is arranged at the bottom of the two support columns;

[0007] Support mechanisms are installed on the top surfaces of the two support columns facing each other. The support mechanism includes a connecting frame connected to the support column, a double-acting cylinder arranged inside the connecting frame, and support plates arranged on the output shafts on both sides of the double-acting cylinder; the outer surface of the support plate is an arc structure, and a punching strip groove is arranged at the center of the outer surface of the support plate;

[0008] A punching mechanism is installed in the top area of the support mechanism.

[0009] Optionally, in the present invention, the displacement mechanism includes a slide rail frame connected to the top of the bottom plate, a double-threaded screw installed inside the slide rail frame, thread nuts symmetrically installed on the double-threaded screw, and a first motor installed outside the slide rail frame and connected to the double-threaded screw; the two support columns are respectively installed on the two thread nuts.

[0010] Optionally, in the present invention, the punching mechanism includes support frames installed on both sides of the bottom plate, an electric drive linear module disposed between the tops of the two support frames, a punching cylinder installed on the driving block of the electric drive linear module, and a punching head installed on the output rod of the punching cylinder.

[0011] Optionally, in the present invention, two mounting holes are provided at the bottom of each of the two support frames.

[0012] Optionally, in the present invention, the punching head and the punching cylinder are connected by an internal and external thread method.

[0013] Optionally, in the present invention, a second motor is installed on the outer side of the support column, the output shaft of the second motor is connected to the center of the connecting frame, and the connecting frame is rotatably connected to the support column.

[0014] Optionally, in the present invention, the connecting frames of the support mechanisms on the two support columns are perpendicular to each other.

[0015] Optionally, in the present invention, a plurality of receiving grooves are equidistantly arranged on the arc-shaped surface of the support plate, and rollers are rotatably connected in the plurality of receiving grooves.

[0016] Optionally, in the present invention, a rubber pad is provided on the surface of the roller.

[0017] The punching process used by any of the above air conditioner condenser manifold punching processing devices includes the following steps:

[0018] Step 1: First, insert the air conditioner manifold to be punched into the two support plates of the support mechanism on one side. Then, hold the manifold and start the displacement mechanism. The first motor operates, causing the two lead screw nuts to drive the two support mechanisms to approach each other, so that the two support plates of the support mechanism on the other side also insert into the interior of the manifold.

[0019] Step 2: Start the support mechanism, operate the double-acting cylinder, so that the two support plates expand outwards, thereby providing a counteracting support to the air conditioner manifold from the inside.

[0020] Step 3: The two second motors operate synchronously, causing the four support plates to rotate synchronously on the air conditioner manifold through the rollers, so that the punching strip grooves are located at the bottom of the punching area. If it is necessary to ensure that the support plates rotate synchronously with the air conditioner manifold, the double-acting cylinder can continue to operate to make the force of the support plates against the inner wall of the air conditioner manifold greater, so that the punching position of the air conditioner manifold faces upwards at the top.

[0021] Step 4: The punching mechanism operates, the electric drive linear module adjusts the lateral position of the punching head, and the punching cylinder operates to perform punching.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] Through the displacement mechanism and the support mechanism, the inner support of the air conditioner header pipes with different inner diameters and lengths can be realized, so that the position remains unchanged during punching. At the same time, through the support plate of the support mechanism, when the air conditioner header pipe is punched, the punching position is supported by the support plate around it, preventing the pipe around the hole position from deforming or cracking during punching, and ensuring the smooth punching of the air conditioner condenser header pipe.

[0024] Moreover, through the operation of the punching mechanism and the second motor, the position of the support plate and the rotation of the header pipe can be adjusted, so that the header pipes at different positions can be automatically punched without manual adjustment, increasing the practicability.

[0038] A punching mechanism 60 is installed in the top area of the support mechanism 50.

[0039] In addition, it should be noted that all the electrical components of this device are electrically connected to a conventional PLC controller.

[0040] Specifically, please refer to the appendix Figure 3 , the displacement mechanism 20 includes a slide rail frame 21 connected to the top of the bottom plate 10, a double-threaded screw rod 22 installed inside the slide rail frame 21, nut blocks 23 symmetrically installed on the double-threaded screw rod 22, and a first motor 24 installed outside the slide rail frame 21 and connected to the double-threaded screw rod 22; the two support columns 30 are respectively installed on the two nut blocks 23.

[0041] It should be noted that in this embodiment, the distance between the two support mechanisms 50 can be adjusted through the displacement mechanism 20, so as to position manifolds with different diameters. By operating the first motor 24, the double-threaded screw rod 22 can be rotated, so that the symmetrically arranged nut blocks 23 approach or move away from each other, so that the support columns 30 on both sides can be inserted into the inside of the manifold.

[0042] Specifically, please refer to the appendixFigure 2 , the punching mechanism 60 includes support frames 61 installed on both sides of the bottom plate 10, an electric drive linear module 62 arranged between the tops of the two support frames 61, a punching cylinder 63 installed on the driving block of the electric drive linear module 62, and a punching head 64 installed on the output rod of the punching cylinder 63.

[0043] It should be noted that in this embodiment, the lateral position of the punching head 64 can be adjusted through the electric drive linear module 62, so as to punch holes at different positions of the manifold.

[0044] Specifically, please refer to the appendix Figure 2 , two mounting holes are provided at the bottoms of the two support frames 61.

[0045] It should be noted that in this embodiment, through the two mounting holes, it is convenient to install the positioning components, so that the support frame 61 is stably installed on the ground or the tabletop, increasing the stability and ensuring the accuracy of the punching position.

[0046] Specifically, please refer to the appendix Figure 2 , the punching head 64 and the punching cylinder 63 are connected by an internal and external thread method.

[0047] It should be noted that in this embodiment, the punching head 64 can be conveniently disassembled by rotating it, so as to replace the punching head 64 with a suitable size.

[0048] Specifically, please refer to the appendix Figure 1 , a second motor 40 is installed on the outer side of the support column 30, the output shaft of the second motor 40 is connected to the center of the connecting frame 51, and the connecting frame 51 is rotatably connected to the support column 30.

[0049] It should be noted that in this embodiment, the rotation of the support mechanism 50 can be realized through the second motor 40, so that the internal support column 30 rotates or the manifold rotates, making the punching position and the internal support column 30 face upward.

[0050] Specifically, please refer to the appendix Figure 3 , the connecting frames 51 of the support mechanisms 50 on the two support columns 30 are perpendicular to each other.

[0051] It should be noted that in this embodiment, the initial positions of the two support columns 30 on both sides are in a vertical state, which is convenient for inserting the air-conditioning manifold into the inside of the support column 30.

[0054] Specifically, please refer to the attached Figure 6 figure, and a rubber pad 541 is provided on the surface of the roller 54.

[0055] It should be noted that in this embodiment, when it is necessary for the support plate 53 and the header pipe to rotate together, the contact between the support plate 53 and the header pipe can be increased, and the rubber pad 541 is used to increase the frictional resistance, so that the support plate 53 and the header pipe rotate together.

[0056] The punching process used by any of the above air conditioner condenser header pipe punching devices includes the following steps:

[0057] Step 1: First, insert the air conditioner header pipe to be punched onto the two support plates 53 of the support mechanism 50 on one side. Then, hold the header pipe and start the displacement mechanism 20. The first motor 24 operates to drive the two lead screw nuts 23 to move the two support mechanisms 50 closer to each other, so that the two support plates 53 of the support mechanism 50 on the other side also insert into the header pipe.

[0058] Step 2: Start the support mechanism 50 to operate the double-acting cylinder 52, so that the two support plates 53 expand outwards to support the air conditioner header pipe from the inside.

[0059] Step 3: The two second motors 40 operate synchronously, so that the four support plates 53 rotate synchronously on the air conditioner header pipe through the rollers 54, so that the punching strip grooves 531 are located at the bottom of the punching area. If it is necessary to ensure that the support plate 53 rotates synchronously with the air conditioner header pipe, the double-acting cylinder 52 can continue to operate to make the force between the support plate 53 and the inner wall of the air conditioner header pipe greater, so that the punching position of the air conditioner header pipe faces upwards to the top.

[0060] Step 4: The punching mechanism 60 operates. The electric drive linear module 62 adjusts the horizontal position of the punching head 64, and the punching cylinder 63 operates to punch holes.

[0061] The present invention has been described exemplarily in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above methods. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
