[0030] Beneficial effects of the present invention:

[0031] (1) When punching a straight tube, the present invention first drives the first die body and the second die body to approach each other through the blanking module, and the lower die body is formed by closing the mold. After the straight tube is punched and formed, the upper die rises and resets. Then, the blanking module drives the first die body and the second die body to approach each other and move away from each other, so that the special-shaped column located in the lower punching groove can be discharged under the action of gravity, thereby achieving the effect of automatic blanking. After the blanking is completed, the blanking module drives the first die body and the second die body to close the mold, so as to facilitate the subsequent punching. In this way, the automatic batch stamping and forming of the straight tube can be realized, which effectively improves the forming efficiency, and does not require manual or mechanical hands to blank the materials, and the safety and stability can be steadily improved.

[0032] (2) Before placing the straight pipe on the downward punching groove, the present invention first drives the positioning frame to move away from each other through the side punching cylinders on both sides to avoid interference during placement. After the straight pipe is placed in the lower punching groove, the side punching cylinders on both sides are started to drive the positioning frame to move toward each other, so that the positioning rod is inserted into the straight pipe, and the positioning plate is abutted against the pipe wall of the straight pipe. During the sliding process of the positioning plate on the positioning rod, the guide rod is driven to slide on one side of the positioning frame to compress the first spring to generate elastic force, thereby achieving the effect of clamping and positioning the straight pipe, and at the same time, improving the stability of the straight pipe during punching, and avoiding the phenomenon of its deviation during the punching process;

[0033] (3) When placing the straight tubes on the loading rack of the present invention, the load-bearing plate is pressed to move them to the bottom of the storage space. During the movement, the load-bearing plate compresses the second spring to generate elastic force. After the straight tubes are placed in the storage space, the limiting frames on both sides are in a mutually fitting state, thereby limiting the straight tubes to prevent the straight tubes from leaving the storage space. After taking a group of the topmost straight tubes, the second spring can drive the load-bearing plate to move upward to the height of a straight tube so as to facilitate taking them again, and this cycle is repeated until all the straight tubes are taken out.

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] Example 1

[0046] See also Figure 2 As shown, the present invention is a forming process for a car headrest connector, comprising the following steps:

[0047] S1, arranging the straight pipe 501 to be processed on the loading rack 6;

[0048] S2, the loading module transfers the straight tube 501 in the loading rack 6 to between the upper mold 3 and the lower mold 301, and positions it through the positioning module;

[0049] S3, after the positioning is completed, the upper die 3 is driven by the stamping cylinder 302 to move toward the lower die 301, so as to stamp the straight tube 501 into a special-shaped column 5;

[0050] S4, after the stamping is completed, the stamping cylinder 302 drives the upper mold 3 to rise to the initial position;

[0051] S5, the blanking module automatically discharges the special-shaped column 5 after stamping;

[0052] Specifically, the present embodiment can automatically discharge the formed special-shaped column 5 by setting a material discharge module, without the need for manual or mechanical material discharge, which not only improves the forming efficiency but also increases safety and is less likely to cause safety accidents.

[0053] Example 2

[0054] Based on Example 1, please refer to Figure 2 , a car headrest connector forming equipment, including a workbench 2, on which an upper mold 3 and a lower mold 301 are arranged respectively, and the upper mold 3 is fixed to the driving end of a stamping cylinder 302 that drives it to rise and fall; specifically, the upper mold 3 is arranged above the lower mold 301, and the stamping cylinder 302 can drive the upper mold 3 to move closer to or away from the lower mold 301 to achieve the effect of mold closing, stamping or demoulding;

[0055] In this embodiment, an upper stamping groove 310 corresponding to the structure of the special-shaped column 5 is opened on the side of the upper mold 3 facing the lower mold 301, and a lower stamping groove 311 corresponding to the structure of the special-shaped column 5 is opened on the side of the lower mold 3 facing the upper mold 3; specifically, during the stamping process, the straight tube 501 is first placed in the lower stamping groove 311 of the lower mold 301, and then the upper mold 3 is driven by the stamping cylinder 302 to move toward the direction of the lower mold 301, so as to form the straight tube 501 in the upper stamping groove 310 and the lower stamping groove 311 to form the special-shaped column 5.

[0056] As a further solution of this embodiment, please refer to Figure 7-Figure 8 The lower mold 301 includes two sets of symmetrically arranged first mold bodies 312 and second mold bodies 313, and the lower mold 301 is formed by combining the first mold body 312 and the second mold body 313;

[0057] The device further comprises a material discharge module, which is used to drive the first mold body 312 and the second mold body 313 to move toward each other or move away from each other;

[0058] It can be explained that, in this embodiment, when stamping the straight tube 501, the first die body 312 and the second die body 313 are first driven by the blanking module to approach each other and close the mold to form the lower mold 3. After the straight tube 501 is stamped and formed, as the upper mold 3 rises and resets, the first die body 312 and the second die body 313 are driven by the blanking module to approach each other and move away from each other, so that the special-shaped column 5 located in the lower stamping groove 311 can be discharged under the action of gravity, thereby achieving the effect of automatic blanking. After the blanking is completed, the blanking module drives the first die body 312 and the second die body 313 to close the mold to facilitate subsequent stamping. In this way, the automatic batch stamping and forming processing of the straight tube 501 can be realized, which effectively improves the forming efficiency and does not require manual or robotic arms to blank the materials, and the safety and stability can be steadily improved.

[0059] See also Figure 2-Figure 5 In this embodiment, before stamping, in order to ensure that the straight tube 501 is in the middle position of the mold, positioning modules for positioning the straight tube 501 are respectively arranged on both sides of the workbench 2, and the two groups of positioning modules respectively include a positioning frame 202 fixedly arranged on the side edge of the workbench 2, and a side-punching cylinder 4 is fixedly arranged on the positioning frame 202. The driving end of the side-punching cylinder 4 is fixed to the positioning frame 401, and a positioning rod 405 for plugging with the straight tube 501 is fixedly arranged at one end of the positioning frame 401 away from the side-punching cylinder 4, wherein a positioning plate 404 is slidably sleeved on the positioning rod 405, and guide rods 402 fixed to the positioning plate 404 are slidably arranged at both ends of the positioning frame 401, and a first spring 403 is arranged on the guide rod 402; specifically, one end of the first spring 403 is fixed to the positioning plate 404, and the other end is fixed to the positioning frame 401. The side plates are fixed; it can be explained that, in this embodiment, before placing the straight tube 501 on the downward punching groove 311, the side punching cylinders 4 on both sides are first used to drive the positioning frame 401 to move away from each other to avoid interference during placement; after the straight tube 501 is placed on the lower punching groove 311, the side punching cylinders 4 on both sides are started to drive the positioning frame 401 to move toward each other, so that the positioning rod 405 is inserted into the straight tube 501, and at the same time, the positioning plate 404 is abutted against the tube wall of the straight tube 501; in the process of the positioning plate 404 sliding on the positioning rod 405, the guide rod 402 is driven to slide on one side of the positioning frame 401 to compress the first spring 403 to generate elastic force, thereby achieving the effect of clamping and positioning the straight tube 501, and at the same time, improving the stability of the straight tube 501 during punching, and avoiding the phenomenon of its displacement during the punching process.

[0060] For further information, see Figure 2 and Figure 5A loading rack 6 is provided on one side of the workbench 2, and two groups of baffle plates 601 are symmetrically arranged at both ends of the loading rack 6, and a storage space for arranging the straight tubes 501 is formed between the two groups of baffle plates 601; specifically, in this embodiment, before the straight tubes 501 are stamped and formed, several groups of straight tubes 501 are first arranged in the storage space in sequence along the vertical direction, and each layer is limited to arranging one group of straight tubes 501.

[0061] In this embodiment, in order to achieve the effect of automatic loading, a carrying plate 602 is slidably arranged in the storage space, and limiting rods 603 are fixedly arranged at both ends of the loading rack 6, and both ends of the carrying plate 602 are slidably connected with the limiting rods 603, and a second spring 604 is also arranged on the limiting rods 603, wherein limiting frames 607 are respectively arranged on the baffle plates 601 on both sides, and the bottom of the limiting frame 607 is slidably connected with a guide column 605 fixedly arranged on the side edge of the baffle plate 601, and a third spring 606 is also arranged on the guide column 605; specifically, one end of the third spring 606 is fixed to the baffle plate 601, and the other end is fixed to the bottom end of the limiting frame 607; it can be It is explained that when placing the straight tube 501 on the loading rack 6, it is moved to the bottom of the storage space by pressing the supporting plate 602. During the movement, it compresses the second spring 604 to generate elastic force. After the straight tube 501 is placed in the storage space, the limiting frames 607 on both sides are in a mutually fitting state, thereby limiting the straight tube 501 to prevent the straight tube 501 from leaving the storage space. After taking a group of the topmost straight tubes 501, the second spring 604 can drive the supporting plate 602 to move upward to the height of a straight tube 501 for easy access again, and so on and so forth until all the straight tubes 501 are taken out.

[0062] Correspondingly, when taking the straight pipe 501, the limiting frames 607 on both sides can be driven to separate first. At this time, the limiting frames 607 drive the third spring 606 to stretch and generate elastic force, so as to drive the limiting frames 607 to return to their original positions after taking is completed.

[0063] Furthermore, the workbench 2 is also provided with a loading module for taking the straight tube 501, and the loading module includes a limit frame 303, one end of the limit frame 303 is fixed to the stamping cylinder 302, and the other end thereof is fixedly provided with a grabbing cylinder 304, and the driving end of the grabbing cylinder 304 is fixed to the lifting plate 502, and grabbing mechanisms are respectively arranged at both ends of the lifting plate 502 for grabbing the straight tube 501; it can be explained that when taking the straight tube 501 on the loading rack 6, the lifting plate 502 can be driven to descend by the grabbing cylinder 304 until the grabbing mechanism grabs the straight tube 501 at the top of the loading rack 6.

[0064] For details, please refer to Figure 5-Figure 6The grabbing mechanism includes a U-shaped plate 503 fixed to the end of the lifting plate 502, an adjusting rod 504 is fixedly arranged at the bottom of the U-shaped plate 503, an adjusting seat 505 is symmetrically slidably sleeved on the adjusting rod 504, and grabbing seats 507 are fixedly arranged at the bottom of the adjusting seats 505 on both sides, and a fourth spring 506 is also provided on the adjusting rod 504, one end of the fourth spring 506 is fixed to the adjusting seat 505, and the other end is fixed to the U-shaped plate 503, and an arc groove 508 for embedding the straight pipe 501 is provided on the side close to the grabbing seats 507 on both sides, wherein a first inclined guide surface 509 is provided on the side close to the bottom of the grabbing seat 507; it can be explained that in the grabbing When the straight tube 501 is grasped, the grabbing cylinder 304 drives the lifting plate 502 to descend until the first inclined guide surface 509 abuts against the tube wall of the straight tube 501. As the lifting plate 502 continues to descend, the tube wall of the straight tube 501 abuts against the first inclined guide surface 509, thereby pushing the grabbing seats 507 on both sides to move backwards, so as to compress the fourth spring 506. When the arc groove 508 moves to correspond to the straight tube 501, the fourth spring 506 can drive the grabbing seats 507 to move toward each other, so as to embed the straight tube 501 into the arc groove 508. As the grabbing cylinder 304 drives the lifting plate 502 to rise, the straight tube 501 can be driven to rise.

[0065] Furthermore, when grabbing the straight pipe 501, in order to avoid interference with the limiting frame 607, in this embodiment, an L-shaped bracket 510 is fixedly arranged on the U-shaped plate 503, and a telescopic sleeve 511 is fixedly arranged at the end of the L-shaped bracket 510. A guide wheel 513 is rotatably arranged at one end of the telescopic sleeve 511 away from the L-shaped bracket 510, and a fifth spring 512 is also arranged on the telescopic sleeve 511, wherein a second inclined guide surface 608 is provided on the adjacent side of the limiting frame 607; specifically, when the lifting plate 502 is at the initial height, The distance between the guide wheel 513 and the loading rack 6 is smaller than the distance between the grabbing seat 507 and the loading rack 6; it can be explained that when grabbing the straight tube 501, as the lifting plate 502 descends, the guide wheels 513 on both sides first abut against the second inclined guide surface 608, and then drive the limit frames 607 on both sides to move away from each other, and as the lifting plate 502 continues to descend, the telescopic sleeve 511 can be synchronously contracted, and accordingly, the grabbing seat 507 grabs the straight tube 501. After the grabbing is completed, as the guide wheel 513 rises, the limit frame 607 is synchronously reset.

[0066] See also Figure 2 and Figure 5A base 1 is also provided at the bottom of the workbench 2, and a translation mechanism 101 is fixedly arranged on the base 1, and a driving end of the translation mechanism 101 is fixed to the limit frame 303; it can be explained that when the lifting plate 502 is directly above the loading rack 6, the upper mold 3 is directly above the lower mold 301, and when the loading module grabs a group of straight tubes 501, the straight tubes 501 can be driven by the translation mechanism 101 to move to directly above the lower mold 301 to realize the loading of the straight tubes 501. Correspondingly, after the placement is completed, the translation mechanism 101 can drive it to reset.

[0067] Specifically, the translation mechanism 101 of this embodiment may adopt a synchronous belt mechanism or a screw transmission mechanism to drive the limiting frame 303 to translate along a straight line, and this embodiment is not limited to this.

[0068] See also Figure 5 and Figure 7 The blanking module includes a screw rod 308 rotatably arranged on the workbench 2, and a nut 309 is spirally sleeved on the screw rod 308 and fixed to the first mold body 312 and the second mold body 313, wherein a gear 307 is fixedly arranged at the end of the screw rod 308, and a driving frame 305 is fixedly arranged at both ends of the upper mold 3, and a rack 306 for meshing with the gear 307 is fixedly arranged at the bottom end of the driving frame 305 through a connecting rod; it can be explained that when the upper mold 3 is at the initial height, the rack 306 and the gear 307 are also in a separated state, At this time, the first mold body 312 and the second mold body 313 are separated synchronously. As the stamping cylinder 302 drives the upper mold 3 to descend, the lower mold 301 drives the rack 306 to descend through the driving frame 305. The rack 306 can drive the screw 308 to rotate by engaging with the gear 307. The nut 309 can drive the first mold body 312 and the second mold body 313 to close the mold during the movement on the screw 308. Correspondingly, as the upper mold 3 rises, the first mold body 312 and the second mold body 313 can be driven to separate, and the formed special-shaped column 5 is automatically unloaded.

[0069] Specifically, a feed chute 201 is opened at a position corresponding to the lower mold 301 on the workbench 2, and a storage box 102 for receiving the special-shaped columns 5 is provided at the bottom of the feed chute 201; specifically, the special-shaped columns 5 that are automatically fed can pass through the feed chute 201 under the action of gravity and fall into the storage box 102 for collection.
