DETAILED DESCRIPTION

[0021] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0022] like Figure 1-Figure 5 As shown, the hot extrusion forming device of small-sized thick-walled titanium alloy pipe provided in this embodiment comprises an extrusion equipment body 3, an extrusion die 1 and a rotating disk 4 arranged on the front of the extrusion equipment body 3, the rotating disk 4 rotates around the center of the extrusion die 1, a slide groove 5 is provided on the front of the extrusion equipment body 3, a stopper 7 is fixedly installed on the end of the slide groove 5 close to the extrusion die 1, a No. 1 slider 2 is slidably connected to the bottom surface of the slide groove 5, a spring groove 9 is provided on the bottom surface of the No. 1 slider 2, a spring 10 is provided in the spring groove 9, the spring 10 is located between the stopper 7 and the No. 1 slider 2, a latch 11 is fixedly connected to the end of the No. 1 slider 2 close to the extrusion die 1, the latch 11 is used to fix the extrusion die 1, a plurality of extrusion grooves 12 are provided on the inner side of the rotating disk 4, and when the rotating disk 4 rotates, the extrusion groove 12 is pressed against the tail of the No. 1 slider 2 For extrusion, a cylinder 13 for pushing the rotating disk 4 to rotate is provided between the rotating disk 4 and the bottom frame of the extrusion equipment body 3. The bottom of the cylinder 13 is rotatably connected to the bottom frame of the extrusion equipment body 3 through a cylinder base 17. The piston rod of the cylinder 13 is rotatably connected to the rotating disk 4 through a rotating shaft 18. When the cylinder 13 is extended, the cylinder 13 pushes the rotating disk 4 to rotate. Under the action of the spring 10, the No. 1 slider 2 moves from the narrower side of the extrusion groove 12 to the other side. At this time, the latch tooth 11 does not contact the surface of the extrusion die 1, and the extrusion die 1 is replaced. When the cylinder 13 is retracted, the extrusion groove 12 pushes the No. 1 slider 2 to move toward the extrusion die 1. When the No. 1 slider 2 is located on the narrower side of the extrusion groove 12, the latch tooth 11 is located above the extrusion die 1 and contacts the upper surface of the extrusion die 1 to fix the extrusion die 1.

[0023] Further, such as Figure 2As shown, an annular groove 14 is provided on the front side of the extrusion equipment body 3, and an annular guide rail 15 is fixedly installed in the annular groove 14. A plurality of No. 2 sliders 16 are slidably connected to the surface of the annular guide rail 15. The surface of the No. 2 sliders 16 is fixedly connected to the rotating disk 4. The No. 2 sliders 16 slide along the annular guide rail 15, and the rotating disk 4 rotates around the center of the annular guide rail 15.

[0024] Furthermore, if Figure 2 As shown, the annular guide rail 15 is a segmented structure, and the multi-segment annular guide rail 15 is fixedly installed with the extrusion equipment body 3 by bolts. The segmentation of the guide rail facilitates the installation of the No. 2 slider 16 and the guide rail.

[0025] Among them, Figure 5 As shown, a No. 1 protrusion 19 is provided on a side of the stopper 7 close to the spring groove 9, and a No. 2 protrusion 20 is provided on a side of the spring groove 9 opposite to the stopper 7. Both ends of the spring 10 are respectively inserted into the No. 1 protrusion 19 and the No. 2 protrusion 20. The No. 1 protrusion 19 and the No. 2 protrusion 20 limit the two ends of the spring 10, so that the sliding process of the No. 1 slider 2 is more stable.

[0026] Among them, Figure 3 As shown, a plurality of pressure plates 21 are fixedly installed on the front side of the extrusion equipment body 3, and limit blocks 22 are provided on both sides of the No. 1 slider 2. Limit grooves 23 are provided on both sides of the pressure plate 21 close to the limit blocks 22. The limit blocks 22 are slidably connected to the limit grooves 23. The pressure plate 21 is connected to the extrusion equipment body 3 by bolts. When the latch teeth 11 are damaged, the pressure plate 21 can be removed by bolts, and the No. 1 slider 2 and the latch teeth 11 can be replaced together. The pressure plate 21 presses the limit blocks 22 on both sides of the No. 1 slider 2, so that the No. 1 slider 2 will not fall off under the pressure of the extrusion head.

[0027] like Figure 1-Figure 5As shown, the principle of the hot extrusion forming device for small-sized thick-walled titanium alloy pipes provided in this embodiment is as follows: the bottom of the cylinder 13 is rotatably connected to the bottom frame of the extrusion equipment body 3 through the cylinder base 17, and the piston rod of the cylinder 13 is rotatably connected to the rotating disk 4 through the rotating shaft 18. When the cylinder 13 is extended, the cylinder 13 pushes the rotating disk 4 to rotate. When the rotating disk 4 rotates, the extrusion groove 12 inside the rotating disk 4 contacts the tail of the No. 1 slider 2. Under the resistance of the spring 10 inside the No. 1 slider 2, the No. 2 slider 2 slides outward along the slide groove 5 and moves from the narrower side of the extrusion groove 12 to the other side. At this time, the latch 11 slides off the surface of the extrusion die 1, thereby pressing the extrusion die 1. For replacement, when the cylinder 13 retracts, the rotating disk 4 rotates in the opposite direction, and the extrusion groove 12 squeezes the tail of the No. 1 slider 2, pushing the No. 1 slider 2 to slide inward along the slide groove 5. When the No. 1 slider 2 is located on the narrower side of the extrusion groove 12, the latch 11 slides to the top of the extrusion die 1 and contacts the upper surface of the extrusion die 1. When the titanium alloy is extruded, the extrusion die 1 resists the latch 11, and the limit blocks 22 on both sides of the pressure plate 21 press the No. 1 slider 2 to fix the No. 2 slider 16, so that the No. 1 slider 2 will not fall off under the pressure of the extrusion head. When the latch 11 is damaged, the pressure plate 21 can be removed by bolts, and the No. 1 slider 2 and the latch 11 can be replaced together.

[0028] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0029] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.

[0030] The above description shows and describes several preferred embodiments of the utility model, but as mentioned above, it should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the utility model concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
