[0030] Embodiment 1:
[0031] As Figures 1 to 7 shown, the automatic probe sleeve 3 forming device of the present utility model includes: an upper die base 1 and a lower die base 2. A profiling space 4 for placing the sleeve 3 is jointly formed between the upper die base 1 and the lower die base 2 along a first direction. An avoidance space 5 for the sleeve 3 to form a tapered tail or a boss 33 is formed within the profiling space 4; a pushing structure 6 and a blocking structure 7. The pushing structure 6 and the blocking structure 7 are respectively located on both sides of the profiling space 4 along the first direction. The blocking structure 7 is used to block the movement of the sleeve 3 within the profiling space 4, and the pushing structure 6 pushes the sleeve 3 to move within the profiling space 4 to a stationary position. With the thrust generated by the pushing structure 6, the tail end 32 of the sleeve 3 is formed into a tapered tail within the avoidance space 5.
[0032] Referring to Figure 1 , the probe sleeve 3 has opposite first end 31 and tail end 32.
[0033] Referring to Figure 3 , the profiling space 4 jointly formed between the upper die base 1 and the lower die base 2 after clamping is in a cylindrical structure to fit the outer shape of the sleeve 3. An avoidance space 5 is formed between the upper die base 1 and the lower die base 2 at the profiling space 4. The avoidance space 5 is located on the side close to the pushing structure 6 and is used for the formation of the tapered tail of the tail end 32 of the sleeve 3.
[0034] Referring to Figure 2 , the pushing structure 6 and the blocking structure 7 are respectively located at both ends of the profiling space 4. The blocking structure 7 forms a limit on the sleeve 3 within the profiling space 4. The pushing structure 6 can push the tail end 32 of the sleeve 3 to move within the profiling structure to a stationary position. And after the sleeve 3 is blocked and limited by the blocking structure 7 and is in a stationary position, the pushing structure 6 continues to apply pressure to the tail end 32 of the sleeve 3, so that the tail end 32 of the sleeve 3 is formed to shrink towards the central axis direction of the sleeve 3 to achieve the shrinkage forming effect. It has the characteristics of simple structure and convenient operation and has practicality.
[0035] In one or more embodiments, the lower die base 2 is formed with a first profiling groove 21, and the upper die base 1 is formed with a second profiling groove 11 adapted to the first profiling groove 21. The lower die base 2 forms a first forming structure 22 at the first profiling groove 21, and the upper die base 1 forms a second forming structure 12 at the second profiling groove 11. The upper die base 1 and the lower die base 2 are configured to be closable for clamping, so that: the first profiling groove 21 and the second profiling groove 11 are closed to form a profiling space 4, and the first forming structure 22 and the second forming structure 12 are closed to form an avoidance space 5.
[0036] See Figure 2 , a first profiling groove 21 and a first forming structure 22 are formed on the lower die base 2, and a second profiling groove 11 and a second forming structure 12 adapted to the lower die base 2 are formed on the upper die base 1. When the upper die base 1 and the lower die base 2 are closed, the first profiling groove 21 and the second profiling groove 11 form a profiling space 4, and the first forming structure 22 and the second forming structure 12 form an avoidance space 5, facilitating the tail-end shrinking forming of the sleeve 3. After the tail end 32 of the sleeve 3 is processed and formed, the upper die base 1 and the lower die base 2 are controlled to be separated, so as to facilitate the removal of the needle holder sleeve 3 with the formed tail end 32.
[0037] In one or more embodiments, the pressing structure 6 includes a first driving device 61 and a pressing member 62. The pressing member 62 is formed with a guiding surface 621 with a gradually decreasing diameter near the avoidance space 5, so that: after the sleeve 3 is pushed to a stationary position, the tail end 32 of the sleeve 3 is squeezed by the guiding surface 621 of the pressing member 62 and shrinks and forms towards the axis direction of the sleeve 3.
[0038] See Figure 2 、 Figure 5 、 Figure 6 , the first driving device 61 can be a cylinder or a rocker assembly pushed by a cylinder, and no specific limitation is made.
[0039] See Figure 6 , the guiding surface 621 can be a conical surface; the guiding surface 621 of the pressing member 62 has a gradually decreasing diameter from the profiling space 4 towards the pressing structure 6. It should be noted that the diameter of the guiding surface 621 on the side close to the profiling space 4 is larger than the outer diameter of the probe sleeve 3, and the diameter of the guiding surface 621 on the side far from the profiling space 4 is smaller than the outer diameter of the probe sleeve 3.
[0040] When the probe sleeve 3 is subjected to tail shrinking forming, first place the probe sleeve 3 in the first profiling groove 21 of the lower die base 2. Subsequently, control the upper die base 1 and the lower die base 2 to close the mold. Then, use the first driving device 61 to control the pusher 62 to move towards the probe sleeve 3, so that the guiding surface 621 of the pusher 62 coaxial with the probe sleeve 3 abuts against the tail end 32 of the probe sleeve 3. As the first driving device 61 operates, the head end 31 of the probe sleeve 3 is abutted by the pusher 62 against the blocking structure 7 to be in a stationary position. After that, the pusher 62 continues to move towards the probe sleeve 3, so that the tail end 32 of the probe sleeve 3 is squeezed by the guiding surface 621 of the conical structure and formed towards the central axis direction of the sleeve 3. After the probe sleeve 3 is formed, control the pushing structure 6 to reset and separate the upper die base 1 and the lower die base 2, and then take out the probe sleeve 3 with the formed tail end 32. The operation is simple, realizing the one-time forming of the tail end 32 of the probe sleeve 3, and having practicability.
[0041] In one or more embodiments, the blocking structure 7 includes a blocking plate 71 disposed on the side of the profiling space 4 away from the pushing structure 6. Refer to Figure 2 , the blocking plate 71 can abut against the head end 31 of the probe sleeve 3 to fix the position of the probe sleeve 3 in the profiling space 4 and ensure the forming of the tail end 32 of the probe sleeve 3.
[0042] In one or more embodiments, the blocking structure 7 further includes a pushing cylinder 72 disposed on the blocking plate 71, and the extending shaft end of the pushing cylinder 72 extends into the profiling space 4. By the extending cylinder of the pushing cylinder 72 extending into the profiling space 4, it is possible to limit the position of the probe sleeve 3 in the profiling space 4, so as to realize the forming of probe sleeves 3 with different lengths without changing the mold, and improve the application range of the present utility model.
[0043] In one or more embodiments, the outer diameter of the avoidance space 5 is larger than the outer diameter of the profiling space 4. Refer to Figure 4 , through this setting, after the tail end 32 of the probe sleeve 3 is formed, it is convenient for the staff to take out the probe sleeve 3 through the first forming structure 22, improving the efficiency of the tail shrinking forming of the probe sleeve 3.
[0044] In one or more embodiments, it further includes a feeding structure 8 disposed on the side parts of the upper die base 1 and the lower die base 2, and the feeding structure 8 can automatically send the sleeve 3 to a predetermined position in the profiling space 4.
[0045] Refer to Figure 2 、 Figure 7, the loading structure 8 includes a pushing cylinder 81, a material box 82 and a material plate 83; wherein, the material plate 83 is driven by the pushing cylinder 81, a through accommodating groove 831 is formed on the material plate 83, the lower surface of the material plate 83 is flush with the upper surface of the lower die base 2, and a discharge port is formed below the material box 82; the pushing cylinder 81 is used to push the material plate 83 through the discharge port of the material box 82, so that the probe sleeve 3 in the material box 82 can enter the accommodating groove 831 of the material plate 83, and then the pushing cylinder 81 pushes the material plate 83 above the lower die base 2, so that the probe sleeve 3 can fall into the first profiling groove 21. After that, the upper die base 1 and the lower die base 2 are closed, and then the pushing structure 6 and the blocking structure 7 are used to form the molding of the tail end 32 of the probe sleeve 3; in this application, the automatic loading method of the probe sleeve 3 by the loading structure 8 can effectively improve the consistency of the loading position of the probe sleeve 3 and improve the forming efficiency of the tail end 32 of the probe sleeve 3.
[0046] In a specific embodiment, the loading structure 8 further includes a vibrating disk, and the vibrating disk is used to vibrate and feed the probe sleeve 3 into the feed port of the material box 82; through this setting, the automatic loading of the probe sleeve 3 can be realized, and the labor cost can be reduced.
[0047] In one or more embodiments, the upper die base 1 is driven by a second driving device 9 to approach or move away from the lower die base 2 in the vertical direction. See Figure 2 , the second driving device 9 can be a cylinder, the cylinder is fixed by a bracket, and the relative movement of the upper die base 1 relative to the lower die base 2 is controlled by the extended shaft end of the cylinder, so that the closing and opening of the upper die base 1 and the lower die base 2 can be realized, which has the characteristics of simple structure and convenient operation.
[0048] Embodiment 2:
[0049] See Figure 1 , Figure 2 , Figures 5 to 8 , as the second embodiment of the present invention, the components that are the same or corresponding to those in the first embodiment are marked with the corresponding reference numerals in the first embodiment, and only the differences between the second embodiment and the first embodiment will be described below.
[0050] The difference between the second embodiment and the first embodiment lies in that the avoidance space 5 formed after the first forming structure 22 of the upper die base 1 and the second forming structure 12 of the lower die base 2 are closed is different. In the second embodiment, the avoidance space 5 is relatively located in the middle of the profiling space 4, and the avoidance space 5 is perpendicular to the profiling space 4. So that the position of the avoidance space 5 is relatively located at the outer wall of the probe sleeve 3. It should be noted that by replacing the upper die base 1 and the lower die base 2, the position of the avoidance space 5 can be changed, and then the formation of the convex ring 33 at different positions on the outer wall of the probe sleeve 3 can be realized.
[0051] During operation, the probe sleeve 3 after the tail end 32 is formed is placed into the first forming structure 22 of the lower mold base 2, the upper mold base 1 and the lower mold base 2 are molded together, and the blocking structure 7 is used to block the opening of one end of the profiling space 4. The blocking structure 7 can be a blocking plate 71, or a pushing cylinder 72 installed on the blocking plate 71, and the extended shaft end of the pushing cylinder 72 can extend into the profiling space 4. Thereafter, the probe sleeve 3 after the tail end 32 is formed is pushed toward the blocking structure 7 to a static position by the pushing structure 6, and with the pressure generated by the pushing structure 6 and the limiting of the blocking structure 7, the outer wall of the probe sleeve 3 is deformed at the junction of the profiling space 4 and the avoidance space 5 to form a convex ring 33. After completing the molding of the convex ring 33 on the outer wall of the probe sleeve 3, the upper mold base 1 and the lower mold base 2 are controlled to separate the molds, and the molded probe sleeve 3 can be taken out. It has the characteristics of high molding efficiency and high molding consistency of the probe sleeve 3 and is practical.
