Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning copper pipes, in particular to a processing device for pure copper air-conditioning connecting pipes. Background Technique

[0002] The outer wall of the pure copper air-conditioning connecting pipe needs to be coated with thermal insulation cotton. The existing thermal insulation cotton can be processed into a sleeve shape and sleeved outside the copper pipe. In order to improve the processing efficiency, after the long copper pipe and the long thermal insulation cotton sleeve are installed, the copper pipe is then cut.

[0003] As a connecting pipe, connecting heads need to be installed at both ends of the cut copper pipe. Therefore, the thermal insulation cotton wrapped at the ends of the copper pipe needs to be trimmed. The operator will manually use a tool to trim the thermal insulation cotton. Since manual operation is not accurate enough and the copper connecting pipe has low hardness, it is easy to scratch the surface of the copper pipe and the cut of the thermal insulation cotton is not flat. Content of the Utility Model

[0004] The purpose of this application is to provide a processing device for pure copper air-conditioning connecting pipes to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the following technical solutions are provided in this application:

Therefore, the directional terms used are for explaining and understanding the present utility model, rather than for limiting the present utility model.

[0016] Such as Figures 1-3A processing device for a pure copper air conditioner connecting pipe shown in the figure includes a base 1 and a cutting assembly installed above the base 1. The cutting assembly includes a fixing member 2, a lifting plate 3, and a screw rod 5. The fixing member 2 is fixedly installed above the base 1. The fixing member 2 is composed of two rings and a fixing plate. The two rings are fixedly installed at both ends of the fixing plate. The rings are fixedly installed above the base 1. A lifting plate 3 is installed between the two rings of the fixing member 2. At the bottom of both ends of the lifting plate 3, a first blade 4 is fixedly installed. The screw rod 5 is movably installed above the base 1. The screw rod 5 is perpendicular to the tabletop of the base 1. The lifting plate 3 is driven to lift by the screw rod 5. There are two lifting plates 3, and the two lifting plates 3 are symmetrically arranged up and down and a first blade 4 is fixedly installed at both ends. On the outer wall of one side of the lifting plate 3, a slider 9 is fixedly installed. The slider 9 is threadedly connected to the screw rod 5. The thread on the screw rod 5 is a double-thread, and the threads on both sides of the screw rod 5 are mirror-symmetrically arranged.

[0017] On the outer walls of the upper and lower sides of the fixing plate of the fixing member 2, two limiting rods 6 are fixedly installed. The two limiting rods 6 are fitted on both sides of the slider 9. The limiting rods 6 are perpendicular to the tabletop of the base 1. A connecting ring 12 is fixedly installed on the outer wall of the fixing plate of the fixing member 2. The screw rod 5 passes through the connecting ring 12 and is connected to the inner wall of the connecting ring 12 through a bearing. A motor 10 is installed at the bottom of the base 1. The output end of the motor 10 passes through the tabletop of the base 1 and is fixedly connected to the bottom end of the screw rod 5.

[0018] Two cylinders 11 are fixedly installed at the bottom of the base 1. The two cylinders 11 are installed on both sides of the motor 10. Two chutes 13 are opened on the tabletop of the base 1. The opening direction of the chutes 13 corresponds to the output direction of the cylinders 11. A second blade 7 is arranged between the two rings of the fixing member 2. The second blade 7 is fixedly connected to the output end of the cylinder 11 through a connecting rod 8. The connecting rod 8 passes through the chutes 13. The first blade 4 is an arc-shaped blade.

[0019] Embodiment: The operator passes a pure copper air conditioner connecting pipe with a heat-insulating cotton sleeve outside through the two circular rings of the fixing member 2 on the base 1. After moving the copper pipe to the position where it needs to be cut, the motor 10 is started. The motor 10 drives the screw rod 5 to rotate. The screw rod 5 rotates inside the connecting ring 12, driving the two lifting plates 3 to merge towards the middle. The limiting rod 6 clamps the slider 9, playing a role in controlling the lifting direction of the lifting plate 3. The first blade 4 cuts the heat-insulating layer outside the copper pipe. After the upper and lower first blades 4 are combined into a circular ring, the heat-insulating layer can be cut without damaging the outer wall of the copper pipe inside the heat-insulating layer. Subsequently, the air cylinder 11 is started, and the output end drives the connecting rod 8 to move towards the copper pipe. The connecting rod 8 moves in the sliding groove 13, and the second blade 7 transversely cuts the heat-insulating layer of the copper pipe. The second blade 7 is located between the two groups of first blades 4. Subsequently, the lifting plate 3 and the connecting rod 8 are reset. The operator can peel off the heat-insulating cotton from the knife mark cut by the second blade 7. The heat-insulating cotton between the two groups of first blades 4 is separated from the copper pipe, and the exposed part of the copper pipe can be used for cutting. After cutting, a copper joint can be installed.
