[0003] The main purpose of this utility model is to provide an automatic copper tube shrinking machine, which can effectively solve the problem of low automation in the background technology, requiring manual intervention during the processing, thus affecting processing efficiency.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an automatic copper tube shrinking machine, including a machine base, a feeding component is provided on one side of the upper surface of the machine base, a gripping and moving component is provided on the upper surface of the machine base to grip the copper tube inside the feeding component, a tube shrinking pre-positioning component is provided on the upper surface of the machine base, and the machine base is sequentially provided with a tube shrinking post-positioning component, a rotating steel tube component, a tube cutting and gripping component, a tube cutting component, and an automatic transfer component.

[0005] Preferably, a protective cover is provided on the upper surface of the machine platform.

[0006] Preferably, the gripping and moving component includes an electric guide rail, which is fixedly mounted on the upper surface of the rotating steel pipe component.

[0007] Preferably, an electric guide block is sleeved and installed in the middle of the electric guide rail, a first hydraulic cylinder is installed on the lower surface of the electric guide block, an installation plate is installed at the output end of the first hydraulic cylinder, and an electric clamp is installed on the lower surface of the installation plate.

[0008] Preferably, the pre-tube shrinking positioning assembly includes a positioning plate, which is fixedly mounted on the upper surface of the machine platform.

[0010] Preferably, a second hydraulic cylinder is mounted on the upper surface of the positioning plate, and the output end of the second hydraulic cylinder is rotatably disposed on the other end surface of the swing plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] (1) First, the copper pipe is manually placed into the feeding assembly. The feeding assembly automatically lifts one copper pipe for separation and waiting to be gripped. At this time, the output end of the first hydraulic cylinder extends and retracts, moving the electric clamp to the position of the copper pipe. The electric clamp then operates to grip the copper pipe. At this time, the electric guide block moves in the middle of the electric guide rail, driving the steel pipe to move. After the steel pipe is moved to the position of the lower clamping plate, it is placed on the surface of the lower clamping plate. At this time, the output end of the second hydraulic cylinder extends and retracts. Because the lower clamping plate is installed on the upper surface of the positioning plate, a swing plate is rotatably installed on one side of the positioning plate, and an upper clamping plate is installed on one end of the swing plate. The second hydraulic cylinder is installed on the upper surface of the positioning plate. The output end rotates and is set on the other end of the swing plate, which drives the swing plate to swing. The upper clamp is set on the upper surface of the lower clamp, and the steel pipe is placed between the upper and lower clamps to fix the steel pipe. At this time, the steel pipe is sent into the rotating steel pipe assembly and automatically locked. The shape and size of the shrinking tube are determined by the replaceable clamp. After the copper tube is shrunk, it is automatically lifted and slid into the transfer position to wait for the cutting tube. The cutting and gripping assembly grips the shrunk copper tube and puts it into the cutting position. The rear shrinking and positioning assembly positions and clamps it, and then the excess part of the copper tube is cut off. After the cutting is completed, the automatic transfer assembly performs the unloading work. This device can continuously process the parts automatically in one line, which improves the processing efficiency. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

A gripping and moving component 2 is provided on the upper surface of the machine base 1 to grip the copper tube inside the feeding component 5. A tube shrinking pre-positioning component 3 is provided on the upper surface of the machine base 1. The machine base 1 is sequentially provided with a tube shrinking post-positioning component 6, a rotating steel tube component 7, a tube cutting and gripping component 8, a tube cutting component 9, and an automatic transfer component 10.

[0021] like Figure 1 As shown, a protective cover 4 is provided on the upper surface of the machine base 1, which can protect the device.

[0022] like Figure 1 , 2As shown in Figures 3 and 4, the gripping and moving component 2 includes an electric guide rail 201, which is fixedly installed on the upper surface of the rotating steel pipe component 7. An electric guide block 202 is sleeved in the middle of the electric guide rail 201. A first hydraulic cylinder 203 is installed on the lower surface of the electric guide block 202. An installation plate 204 is installed on the output end of the first hydraulic cylinder 203. An electric clamp 205 is installed on the lower surface of the installation plate 204. The electric clamp 205 is moved to the position of the copper pipe by extending and retracting the output end of the first hydraulic cylinder 203. At this time, the electric clamp 205 works to grip the copper pipe. At this time, the electric guide block 202 moves in the middle of the electric guide rail 201, driving the steel pipe to move.

[0023] like Figure 1 , 2 As shown in Figures 3 and 5, the pre-reduction positioning assembly 3 includes a positioning plate 301, which is fixedly installed on the upper surface of the machine base 1. A lower clamping plate 302 is installed on the upper surface of the positioning plate 301. A swing plate 304 is rotatably installed on one side surface of the positioning plate 301. An upper clamping plate 305 is installed on one end surface of the swing plate 304. A second hydraulic cylinder 303 is installed on the upper surface of the positioning plate 301. The output end of the second hydraulic cylinder 303 is rotatably disposed on the other end surface of the swing plate 304. After the steel pipe is moved to the position of the lower clamping plate 302, the steel pipe is placed on the surface of the lower clamping plate 302. At this time, the extension and retraction are performed by the output end of the second hydraulic cylinder 303. Because the lower clamping plate 302 is installed on the upper surface of the positioning plate 301, the swing plate 304 is rotatably installed on one side surface of the positioning plate 301, the upper clamping plate 305 is installed on one end surface of the swing plate 304, and the second hydraulic cylinder 303 is installed on the upper surface of the positioning plate 301. The output end of the second hydraulic cylinder 303 is rotatably set on the other end surface of the swing plate 304, which will drive the swing plate 304 to swing, so that the upper clamping plate 305 is placed on the upper surface of the lower clamping plate 302, and the steel pipe is placed between the upper clamping plate 305 and the lower clamping plate 302 to fix the steel pipe.

[0024] The working principle of this automatic copper tube shrinking machine:

[0025] In use, the copper tube is first manually placed into the feeding assembly 5. The feeding assembly 5 automatically lifts one copper tube for separation and awaits gripping. At this time, the output end of the first hydraulic cylinder 203 extends and retracts, moving the electric clamp 205 to the position of the copper tube. The electric clamp 205 then operates to grip the copper tube. The electric guide block 202 moves along the middle of the electric guide rail 201, moving the steel tube to the position of the lower clamping plate 302. The steel tube is then placed on the surface of the lower clamping plate 302. The output end of the second hydraulic cylinder 303 extends and retracts. Because the lower clamping plate 302 is installed on the upper surface of the positioning plate 301, and a swing plate 304 is rotatably installed on one side of the positioning plate 301, with an upper clamping plate 305 installed on one end of the swing plate 304. The second hydraulic cylinder 305 is installed on the upper surface of the positioning plate 301. The output end of the hydraulic cylinder 303 is rotated and set on the other end of the swing plate 304, which drives the swing plate 304 to swing. The upper clamping plate 305 is set on the upper surface of the lower clamping plate 302, and the steel pipe is placed between the upper clamping plate 305 and the lower clamping plate 302 to fix the steel pipe. At this time, the steel pipe is sent into the rotating steel pipe assembly 7 and automatically locked. The shape and size of the shrinking tube are determined by the replaceable clamp. After the copper tube is shrunk, it is automatically lifted and slid into the transfer position to wait for the cutting tube. The cutting tube gripping assembly 8 grips the shrunk copper tube and puts it into the cutting position. The rear shrinking and positioning assembly 6 positions and clamps it, and then the excess part of the copper tube is cut off. After the cutting is completed, the automatic transfer assembly 10 performs the unloading work. This device can continuously process the parts automatically in one line, which improves the processing efficiency.
