[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] Example:

[0021] See also Figure 1 - Figure 3The utility model provides a technical solution: an aluminum tube octagonal lock sleeve extrusion molding device, including a bottom plate 1, a first fixing frame 2 and a second fixing frame 3 are fixedly connected to the top of the bottom plate 1, a fixed clamping die assembly 4 is fixedly connected to the outside of the second fixing frame 3, a mobile clamping die assembly 5 is fixedly connected to the outside of the first fixing frame 2, a positioning assembly 6 is fixedly connected to the top of the bottom plate 1 and located between the fixed clamping die assembly 4 and the mobile clamping die assembly 5, an anti-movement assembly 7 is provided inside the fixed clamping die assembly 4 and the mobile clamping die assembly 5, and the fixed clamping die assembly 4 includes a first fixed block 41, the first fixed block 41 is fixedly connected to the outside of the second fixing frame 3, and the first fixed block 41 is away from the second fixing frame 3. The side is fixedly connected with the first clamping die 42, and the movable clamping die assembly 5 includes an electric cylinder 51, the electric cylinder 51 is fixedly connected to the outside of the first fixed frame 2, and one end of the electric cylinder 51 extends to the outside of the first fixed frame 2, one end of the electric cylinder 51 is fixedly connected to the second fixed block 52, and the side of the second fixed block 52 away from the electric cylinder 51 is fixedly connected to the second clamping die 53, and the second clamping die 53 is driven by the electric cylinder 51 to move in the direction of the first clamping die 42 until it hits the first clamping die 42 to squeeze the sleeve into the octagonal shape of the crimping die and fix the sleeve on the pipe, and then the electric cylinder 51 retreats to drive the second clamping die 53 to retreat to its original position, and the crimped product is taken out and the processing is completed.

[0022] Furthermore, the positioning assembly 6 includes a positioning plate 61, which is fixedly connected to the top of the base plate 1. Two positioning blocks 63 are fixedly connected inside the positioning plate 61. Two positioning grooves 62 are provided inside the second clamp 53, and the two positioning blocks 63 are slidably connected to the positioning grooves 62. During the movement of the second clamp 53, the second clamp 53 slides synchronously on the outside of the positioning block 63 through the positioning grooves 62 provided in the second clamp 53, so that the second clamp 53 is not prone to position deviation when moving, thereby improving the processing accuracy.

[0023] Furthermore, the anti-movement assembly 7 includes a fixing rod 71, and the two fixing rods 71 ​​are respectively fixedly connected to the inside of the first clamping mold 42 and the second clamping mold 53, and the outside of the two fixing rods 71 ​​is provided with a spring 72, and the two ends of the two springs 72 and the outside of the fixing rods 71 ​​are fixedly connected with a slider 73, and the outside of each slider 73 is fixedly connected with a first connecting rod 74, and the outside of each first connecting rod 74 is rotatably connected with a second connecting rod 75, and the end of each second connecting rod 75 away from the first connecting rod 74 is fixedly connected with an anti-movement clamp 76, and the outside of each anti-movement clamp 76 is provided with a rack 77. When the pipe and the sleeve are placed on the clamping mold, under the action of pressure, the anti-movement clamp 7 6 will extend into the interior of the clamp through the second connecting rod 75. When the anti-movement clamp block 76 extends into the interior of the clamp, the second connecting rod 75 and the first connecting rod 74 will drive the two sliders 73 to approach each other. At this time, the spring 72 will be squeezed. When the tube and the sleeve are completely located on the clamp, the spring 72 in the clamp will reset, driving the two sliders 73 away from each other. Through the connection between the first connecting rod 74 and the second connecting rod 75, the anti-movement clamp block 76 will be extended to the outside of the clamp. Thus, the sleeve and the tube are fixed by the two anti-movement clamp blocks 76 and the provided rack 77 to prevent movement during the extrusion process, thereby improving the quality and efficiency of the processing.

[0024] In summary: when in use, the tube is placed on the first clamp 42, and the sleeve is placed on the second clamp 53. Through the anti-movement component 7 arranged inside the first clamp 42 and the second clamp 53, when the tube and the sleeve are placed on the clamp, under the action of pressure, the anti-movement clamp 76 will extend into the inside of the clamp through the second connecting rod 75. When the anti-movement clamp 76 extends into the inside of the clamp, the second connecting rod 75 and the first connecting rod 74 will drive the two sliders 73 to approach each other. At this time, the spring 72 will be squeezed. When the tube and the sleeve are completely located on the clamp, at this time, the spring 72 in the clamp will reset, driving the two sliders 73 away from each other, and through the connection of the first connecting rod 74 and the second connecting rod 75, the anti-movement clamp 76 is driven to extend to the outside of the clamp. Thus, the sleeve and the tube are fixed by the two anti-movement clamps 76 and the arranged rack 77 to prevent movement during the extrusion process, thereby improving the processing quality and efficiency. When the tube and the sleeve are fixed, the electric cylinder 51 can be started, and the second clamping die 53 is driven by the electric cylinder 51 to move in the direction of the first clamping die 42 until it hits the first clamping die 42 to squeeze the sleeve into the octagonal shape of the crimping die, and the sleeve is fixed on the tube. Then the electric cylinder 51 retreats to drive the second clamping die 53 to retreat to its original position, and the crimped product is taken out. The processing is completed. During the movement of the second clamping die 53, the positioning groove 62 set in the second clamping die 53 slides synchronously on the outside of the positioning block 63, so that the second clamping die 53 is not prone to position displacement when moving, thereby improving the processing accuracy. Therefore, by using the octagonal method to fix the sleeve, the problem of sleeve rotation that may occur in the original method is effectively solved, and the two-step heading processing technology is also reduced. It is also effectively simplified The processing technology, reduce the raw materials used for the two-step heading, greatly reduce the processing cost, reduce the heading steps, and reduce the processing materials.
