[0002] Tubular parts are hollow cylindrical structures with cross-sections that are typically circular, square, rectangular, or other regular shapes. When flattening and punching the ends of tubular parts to produce specific tubular parts, a stamping die is usually used. The produced parts are commonly used in fields such as automotive control arm connectors and door hinge brackets.

[0003] However, when using traditional molds to flatten and punch pipe fittings, the pipe fittings are usually manually assisted and aligned with the center of the mold. In order to prevent the pipe fittings from shifting due to uneven force during the stamping process, the operator needs to press the pipe fittings continuously during the stamping process, which is cumbersome and lacks flexibility.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 5As shown, this utility model embodiment provides an automatic forming mold for tubular parts, specifically including a lower template 1, a fixing structure 4 connected to the lower template 1, the fixing structure 4 including a slide plate 402, the slide plate 402 slidably connected to the lower template 1, a guide strip 410 fixedly connected to the slide plate 402, and a mounting block 405 slidably connected to the guide strip 410. During the stamping process of the round tube 5, the mounting block 405 slides down along the guide strip 410 and stretches the second tension spring 404, thereby allowing the lower fixing strip 406 to buffer downwards during the stamping process, ensuring that the end of the round tube 5 can be flattened towards the middle, providing high flexibility. The bottom surface of mounting block 405 abuts against slide plate 402. A lower fixing strip 406 is fixedly connected to the top of mounting block 405. Connecting rods 407 are fixedly connected to both ends of the lower fixing strip 406. An upper fixing strip 408 is slidably connected between the two connecting rods 407. A sliding rod 401 is fixedly connected to the lower template 1. Slide plate 402 is slidably connected to sliding rod 401. A first tension spring 403 is fixedly connected between the end face of slide plate 402 and lower template 1. A second tension spring 404 is fixedly connected between the end of mounting block 405 and guide strip 410. A spring is fixedly connected between the end of upper fixing strip 408 and connecting rod 407. 409. A round tube 5 abuts between the upper fixing strip 408 and the lower fixing strip 406. A pull ring 411 is threadedly connected to the upper fixing strip 408. The pull ring 411 is threadedly connected to the upper fixing strip 408, and the distance of the bottom of the pull ring 411 extending out can be adjusted, thus easily adapting to round tubes 5 of different sizes, providing high flexibility. The bottom of the pull ring 411 abuts against the round tube 5. Both the upper fixing strip 408 and the lower fixing strip 406 have an arc-shaped structure, and the connecting rod 407 has a "T"-shaped structure. To avoid the problem of the tube shifting during the stamping process due to improper positioning or uneven force, it is only necessary to fix the tube body before stamping. Before stamping, lift the pull ring 411 upwards. The pull ring 411 drives the upper fixing bar 408 to move upwards along the two connecting rods 407 and compresses the spring 409. Then, pull the mounting block 405 outwards, so that the slide plate 402 slides outwards along the slide rod 401 and stretches the first tension spring 403, pulling the mounting block 405 outwards to facilitate the placement of the round tube 5. Then, pass the tube through the center position of the upper fixing bar 408 and the lower fixing bar 406. Then, lower the pull ring 411. Under the elastic force of the spring 409, the upper fixing bar 408 drives the bottom of the pull ring 411 to abut against the round tube 5. At this time, the lateral position of the round tube 5 can be limited.

[0020] Please see Figures 1 to 5As shown, a driving structure 2 is connected to the lower template 1. The driving structure 2 includes an upper template 201, which is located directly above the lower template 1. A connecting plate 202 is fixedly connected to the bottom surface of the upper template 201. Two guide rods 206 are fixedly connected between the connecting plate 202 and the upper template 201. Two sliding sleeves 205 are fixedly connected to the lower template 1. The guide rods 206 are slidably connected to the adjacent sliding sleeves 205. A stamping plate 203 is located below the connecting plate 202. The stamping plate 203 is connected to the connecting plate 202 by means of... Four rubber pillars 204 are fixedly connected and are respectively located at the four corners of the stamping plate 203. Two guide rods 206 are symmetrically arranged. The cross-section of the stamping plate 203 is U-shaped. The stamping structure 3 is installed on the upper template 201. Then, the press drives the upper template 201 and the connecting plate 202 to move downward. At this time, the two guide rods 206 on the bottom surface of the upper template 201 slide downward along the sliding sleeve 205 on the lower template 1. The setting of the guide rods 206 ensures the stability of the upper template 201 during the downward movement.

[0021] Please see Figures 1 to 5 As shown, the stamping structure 3 includes a stamping block 301. The stamping block 301 is fixedly connected to the bottom surface of the upper template 201. Two punching strips 302 are fixedly connected between the upper template 201 and the connecting plate 202. An upper pressing block 303 is fixedly connected to the bottom surface of the stamping plate 203. The stamping block 301 and the punching strips 302 are slidably connected to the stamping plate 203 and the upper pressing block 303. A lower pressing block 304 is provided directly below the upper pressing block 303. The lower pressing block 304 is fixedly connected to the lower template 1. Two stamping holes 305 are opened on the lower pressing block 304. Then, the upper template 201 drives the bottom stamping plate 203 and the upper pressing block 303 to move downwards and... The press squeezes the round tube 5 directly below. At this time, the upper pressure block 303 and the lower pressure block 304 flatten the end of the round tube 5. When the end of the round tube 5 has been completely flattened and the upper pressure block 303 can no longer move down, the press continues to drive the upper template 201 to move down, which will compress the four rubber pillars 204. This ensures that the upper template 201 can continue to drive the punching block 301 and the punching strip 302 to continue to move down. At this time, the punching strip 302 moves inward toward the punching hole 305, so that the punching strip 302 can punch the end of the round tube 5. At the same time, the punching block 301 can cut the round tube 5. The operation is simple and the punching efficiency is high.

[0022] In use, to avoid the pipe fitting shifting during stamping due to improper positioning or uneven force, this invention only requires fixing the pipe body before stamping. Therefore, before stamping, first lift the pull ring 411 upwards. The pull ring 411 drives the upper fixing strip 408 to move upwards along the two connecting rods 407 and compresses the spring 409. Then, pull the mounting block 405 outwards, causing the slide plate 402 to slide outwards along the slide rod 401 and stretching the first tension spring 403, pulling the mounting block 405 outwards to facilitate the placement of the round pipe 5. Then, the pipe fitting is moved from the middle of the upper fixing strip 408 and the lower fixing strip 406. After the tube passes through the center position, the pull ring 411 is lowered. Under the elastic force of the spring 409, the upper fixing bar 408 drives the bottom of the pull ring 411 to abut against the round tube 5. At this time, the lateral position of the round tube 5 can be limited. At the same time, the pull ring 411 is threadedly connected to the upper fixing bar 408, and the distance of the bottom of the pull ring 411 can be adjusted, so as to adapt to round tubes 5 of different sizes, which is highly flexible. Then, the round tube 5 is pushed towards the mold until the end of the round tube 5 is pushed between the upper pressure block 303 and the lower pressure block 304. At the same time, during the stamping process of the round tube 5, the mounting block 405 moves along the guide bar 4 10. The lower platen 201 slides down and stretches the second tension spring 404, thereby allowing the lower fixing bar 406 to buffer downwards during the stamping process, ensuring that the end of the round tube 5 can be flattened towards the middle, providing high flexibility. Then, the press drives the upper template 201 and connecting plate 202 to move downwards. At this time, the two guide rods 206 on the bottom surface of the upper template 201 slide downwards along the sliding sleeve 205 on the lower template 1. The setting of the guide rods 206 ensures the stability of the upper template 201 during the downward movement. Then, the upper template 201 drives the bottom stamping plate 203 and the upper pressure block 303 to move downwards and squeeze the round tube 5 directly below. At this time, the upper pressure... Block 303, in conjunction with lower pressing block 304, flattens the end of the round tube 5. When the end of the round tube 5 is completely flattened and upper pressing block 303 can no longer move downward, the press continues to drive upper template 201 downward, which in turn compresses the four rubber pillars 204, ensuring that upper template 201 can continue to drive punching block 301 and punching strip 302 to continue moving downward. At this time, punching strip 302 moves inward toward the punching hole 305, thereby punching the end of the round tube 5. At the same time, punching block 301 can cut the round tube 5. The operation is simple and the punching efficiency is high.
