[0031] Example 1

[0032] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-7 A part punching device that facilitates depth control includes a lower template 10, an upper template 11, a positioning punching assembly 40 and a processing punching assembly 50 disposed between the lower template 10 and the upper template 11.

[0033] The positioning punching assembly 40 includes a first support mold 41, a fixing block 42, a positioning punch 43, and a positioning punch pin 44. The fixing block 42 is fixedly installed on the lower template 10, and the first support mold 41, which cooperates to support the inner tube 20, is fixedly installed on the fixing block 42. The first support mold 41 has a positioning punch 43 for forming the positioning hole 22 at one end away from the fixing block 42, and the positioning punch pin 44, which cooperates with the positioning punch 43, is fixedly installed on the upper template 11. The first support mold 41 is also provided with a depth adjustment assembly 30 for adjusting the position of the positioning hole 22 on the finished inner tube 20.

[0034] The processing and punching assembly 50 includes a second support mold 51, a second fixing block 52, processing punches 53, processing punch pins 54, and a third fixing block 55. The second fixing block 52 and the third fixing block 55 are fixedly installed on the lower template 10, with the third fixing block 55 located in front of the second fixing block 52. The third fixing block 55 has a through hole. The second fixing block 52 has a second support mold 51 for cooperating with and supporting the inner tube 20. One end of the second support mold 51 away from the second fixing block 52 passes through the through hole of the third fixing block 55, and there is a gap between the through hole and the third fixing block 55 to accommodate the tube. The second support mold 51 has a plurality of processing punches 53 for forming locking holes 21. The upper template 11 has a processing punch pin 54 for cooperating with the processing punches 53. The third fixing block 55 has a positioning assembly 60 for positioning the positioning holes 22 on the inner tube 20.

[0035] In this invention, one end of the pipe is first inserted into the first support mold 41, and the end of the pipe is blocked by the depth adjustment component 30 on the first support mold 41, which determines the insertion depth of the pipe and the first support mold 41. The press drives the positioning punch 44 to press down through the upper template 11, and the positioning punch 44 penetrates into the positioning punch 43 to form a positioning hole 22 on the pipe. Then the pipe is reversed and the other end of the pipe is inserted into the second support mold 51 until the positioning hole 22 on the pipe is aligned with the positioning component 60, which determines the insertion depth of the pipe and the second support mold 51. The press drives the processing punch 54 to press down through the upper template 11, and the processing punch 54 penetrates into the processing punch 53 to form a locking hole 21 on the pipe, thus completing the processing of the inner layer pipe 20.

[0036] In this utility model, the insertion depth of the tube and the first support mold 41 can be adjusted by adjusting the depth adjustment component 30, thereby changing the forming position of the positioning hole 22 on the tube. Then, the insertion depth of the tube and the fixing block 42 can be adjusted by aligning the positioning component 60 and the positioning hole 22, thereby adjusting the forming position of the locking hole 21 on the tube. This meets the processing requirements of different inner tubes 20, which is not only easy to operate, but also has high processing accuracy and low processing cost, making it suitable for processing small batches of inner tubes 20.

[0037] The depth adjustment component 30 includes a slider 31, a locking knob 33, and a stop 34. A slide rail 32 is fixedly installed on the lower template 10, and the slider 31 is slidably connected to the slide rail 32. One end of the stop 34 is fixedly connected to the slider 31, and the other end of the stop 34 is slidably connected to the first support mold 41. When the tube is inserted into the first support mold 41, the end of the tube will be blocked by the stop 34. By controlling the sliding of the stop 34 on the first support mold 41, the blocking position of the stop 34 on the tube can be changed. The stop 34 is also provided with a locking knob 33 for locking the slider 31 on the slide rail 32. By rotating the locking knob 33, the slider 31 can be locked, and the position of the stop 34 can be fixed.

[0038] The positioning component 60 includes a connecting plate 61, a positioning pin 62, a pull plate 63, and a spring 64. The connecting plate 61 is fixedly connected to the fixing block 55, and the positioning pin 62 is slidably provided on the connecting plate 61. The pull plate 63 is fixedly installed at the end of the positioning pin 62. The spring 64 is sleeved on the positioning pin 62, and the two ends of the spring 64 are fixedly connected to the pull plate 63 and the connecting plate 61, respectively.

[0039] The end of the positioning pin 62 near the second support mold 51 is set as a ball head. When the pipe is inserted into the second support mold 51, the pipe will push the positioning pin 62 up through the ball head. When the positioning hole 22 on the pipe is aligned with the ball head, the spring 64 will drive the positioning pin 62 to reset, so that the positioning pin 62 is stuck in the positioning hole 22 of the pipe. The ball head of the positioning pin 62 and the positioning hole 22 achieve precise positioning of the insertion depth and insertion angle of the pipe.

[0040] A drive motor 56 is fixedly installed on the second fixed block 52. The drive motor 56 is equipped with an encoder to control the number of full rotations of the output end of the drive motor 56 each time. The output end of the drive motor 56 is fixedly connected to the second support mold 51 through a coupling to control the rotation of the second support mold 51. After the locking hole 21 of the tube is formed, the edge of the locking hole 21 will be slightly recessed into the tube, forming burrs, which is not conducive to the assembly of the telescopic sleeve structure. At this time, the tube is manually grasped, and the second support mold 51 is rotated several times by the drive motor 56 to grind and remove the burrs inside the tube, realizing the integrated operation of forming and deburring the locking hole 21, effectively improving the processing efficiency of the inner tube 20.

[0041] Multiple matching positioning blocks 13 are fixedly installed on both the lower template 10 and the upper template 11. When the upper template 11 is pressed down, the positioning blocks 13 on the lower template 10 and the upper template 11 abut against each other, which not only plays a buffering role between the lower template 10 and the upper template 11, but also limits the stroke of the upper template 11, so that the processed inner tube 20 meets the set requirements.

[0042] The first support mold 41 and the second support mold 51 are both provided with waste discharge grooves 14 on their lower sides. The waste discharge groove 14 of the first support mold 41 is connected to the positioning punch 43, and the waste discharge groove 14 of the second support mold 51 is connected to the processing punch 53 to prevent punching waste from getting stuck in the punch.

[0043] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
