[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present invention.

[0024] Embodiment:

[0025] As Figure 1-Figure 8 shown, the stamping tooling for the metal pipe fitting mold of the automotive seat described in this embodiment includes a base 1. The base 1 is in a "U" shape. Among them, the mold 5 includes an upper mold 51 and a lower mold 52. The lower end surface of the upper mold 51 and the upper end surface of the lower mold 52 are both provided with long channels 511 with a semicircular cross-section. The two long channels 511 are symmetrically joined to form a long cavity with a circular cross-section. A punch 53 is movably arranged on the lower mold 52. The lower end surface of the punch 53 is provided with a forming protrusion 531 for forming the depression on the pipe fitting. The forming protrusion 531 is located in the long channel 511 of the upper mold 51.

[0026] It also includes a telescopic cylinder 8 and a clamping mechanism 2. A long groove 11 is arranged on the base 1 along its length direction. The clamping mechanism 2 and the mold 5 are both arranged in the long groove 11, so that the clamping and stamping forming of the metal pipe fitting 100 are both formed on the base 1, realizing modular setting.

[0027] The clamping mechanism 2 includes a block 21, two clamping blocks 23 arranged opposite to each other, a positioning block 24 and two clamping cylinders 22. The telescopic cylinder 8 and the mold 5 are respectively installed on the base 1 at the two ends of the elongated slot 11. A sliding slot 211 is provided on the block 21. The telescopic rod of the telescopic cylinder 8 is fixedly connected to the block 21 through a connecting plate 7. The connecting plate 7 closes the rear port of the sliding slot 211. The two clamping blocks 23 and the positioning block 24 are both arranged in the sliding slot 211. The two clamping cylinders 22 are respectively fixed to the front and rear ends of the block 21, and the telescopic rods of the two clamping cylinders 22 are respectively fixedly connected to the two clamping blocks 23. The lower parts of the two clamping blocks 23 are respectively provided with guide grooves 232. The two ends of the positioning block 24 are respectively placed in the guide grooves on each of the clamping blocks 23. The inner wall of the positioning block 24 and the inner walls of the two clamping blocks 23 are respectively provided with arc grooves 231. The arc grooves 231 of the three are combined to form a clamping circular hole 26 for positioning the pipe fitting. A circular through hole 212 coaxially arranged with the clamping circular hole 26 is set on the side of the block 21 facing the mold 5. The diameter of the circular through hole is larger than the diameter of the clamping circular hole. The clamping circular hole is coaxially arranged with the circular forming cavity formed on the mold 5. The area between the mold 5 and the telescopic cylinder 8 in the elongated groove 11 is slidably installed with a mounting block 3. A locking structure for locking the mounting block 3 after displacement adjustment is set between the mounting block 3 and the bottom of the elongated groove 11. A contact switch 4 is set on the mounting block 3. The contact switch 4 is connected to and controlled by the PLC controller. The telescopic cylinder 8 and the two clamping cylinders 22 are connected to and controlled by the PLC controller through an air pump. In order to make the metal pipe fitting 100 firmly and stably clamped, a clamping structure for increasing friction is set on the inner wall of each of the arc grooves 231. The clamping structure is a rubber pad 25.

[0028] After the end of the metal pipe 100 passes through the circular through hole and is inserted between the three arc-shaped grooves 231, and the lower outer wall of the end of the metal pipe 100 is first positioned on the arc-shaped groove 231 of the positioning block 24, then the telescopic rods of the two clamping cylinders 22 are extended to drive the clamping block 23 to move closer to the outer wall of the metal pipe 100, so that the rubber pad on the inner wall of the arc-shaped groove 231 contacts the outer wall of the metal pipe 100, thereby clamping the end of the metal pipe 100. Then, the piston rod of the telescopic cylinder 8 is extended to drive the clamping block 23 to move closer to the outer wall of the metal pipe 100. The holding mechanism 2 is translated toward the mold 5, so that the end of the metal pipe 100 to be stamped is inserted into the circular forming cavity, and then the clamping block 23 contacts the contact switch 4 on the mounting block 3. At this time, the PLC controller controls the air pump to stop working after receiving the signal from the contact switch 4, thereby causing the metal pipe 100 to move. Finally, the punch 53 rushes downward to stamp a groove 101 at the end of the metal pipe 100. After completion, the telescopic cylinder 8 drives the clamping mechanism 2 and the metal pipe 100 to retreat and reset.

[0029] In this embodiment, a sliding groove 12 is provided in the area between the mold 5 and the telescopic cylinder 8 in the elongated groove 11, and an elongated positioning groove is provided on the inner wall of the sliding groove 12 along its length direction. The lower part of the mounting block 3 is arranged in the sliding groove 12, and the convex part of the lower part of the mounting block 3 is inserted into the elongated positioning groove. The locking structure includes a plurality of adjustment holes 13 provided on the upper side wall of the elongated positioning groove. The plurality of adjustment holes 13 are arranged in a straight line along the length direction of the elongated positioning groove. The mounting block 3 can be operated to translate along the length direction of the sliding groove 12 and stop when translated to a preset position. An adjusting bolt is threadedly connected to the adjusting hole 13, and the end of the adjusting bolt abuts against the convex part of the lower part of the mounting block 3 to adjust the position of the mounting block 3 and fix it, so as to adjust and process the metal pipe 100 according to different lengths; preferably, the upper side wall of the sliding groove 12 can be formed by fixing a strip member on the edge of the sliding groove 12, and the fixation can be bolted or welded.

[0030] In this embodiment, a guide rod 6 is also included, one end of which is connected to the connecting plate 7 on the clamping mechanism 2, and the other end of which is passed through the baffle plate located on the elongated groove 11 at the mold 5. The guide rod 6 is also passed through the lower mold 52 of the mold 5. Its structural setting makes the displacement of the clamping mechanism 2 more stable, so that the metal pipe 100 can be accurately inserted into the circular forming cavity. The guide rod 6 is made of metal material, and the end of the guide rod 6 is threadedly connected with a nut to limit the translation of the guide rod 6.

[0031] The present utility model is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, any technical solution that is the same or similar to that of the present application will fall within the protection scope of the present utility model.
