[0024] The specific embodiments of the present invention will be described below with reference to the accompanying drawings. In order to fully understand the present invention, many details are described below, but for those skilled in the art, the present invention can be implemented without these details.

[0025] like Figure 1 and Figure 2 As shown, a semi-finished product a-1 for a seat belt traction guide has an oblique cutout a2 and a T-shaped plate a1 at one end. The present invention is used to positionally punch a positioning groove a3 at one end of the semi-finished product a-1 to produce a semi-finished product a-2 for a seat belt traction guide. The structure is as follows:

[0026] like Figures 3 to 6 As shown, a stamping die for positioning automotive parts includes a mounting platform 1 equipped with a transverse clamping mechanism 2, a longitudinal clamping mechanism 3, and a stamping assembly 5. The transverse clamping mechanism 2 is used to secure the center of a semi-finished product a-1, while the longitudinal clamping mechanism 3 is used to secure both ends of the semi-finished product a-1, thereby achieving positioning of the semi-finished product a-1. The stamping assembly 5 is used to form a positioning groove a3.

[0027] like Figure 3 and Figure 4 As shown, the transverse clamping mechanism 2 includes a second slide rail 21, a fixed block 22 is fixed to the second slide rail 21, a second slider 23 is movably provided toward the fixed block 22, and a second cylinder 24 is provided for driving the second slider 23, and both the fixed block 22 and the second slider 23 are provided with a clamping groove 20.

[0028] Preferably, the first slide rail 405 is provided with a placement platform 212 for supporting the semi-finished product a-1. Two placement platforms 212 are provided on the first slide rail 405, arranged longitudinally. The upper end surfaces of the placement platforms 212 should be flush with or slightly lower than the clamping groove 20 to ensure that the center of the semi-finished product a-1 is clamped between the two clamping grooves 20 when the fixing block 22 and the second slide block 23 are brought together.

[0029] like Figure 3 and Figure 4As shown, when in use, the semi-finished product a-1 is placed on the placement table 212; then, the second cylinder 24 drives the second slider 23 to move horizontally, so that the fixed block 22 and the second slider 23 are close to each other, and the clamping groove 20 is used to reinforce the middle part of the semi-finished product a-1 to complete the horizontal positioning of the semi-finished product a-1.

[0030] like Figure 2 、 Figure 3 and Figure 5 As shown, the longitudinal clamping mechanism 3 includes a third slider 31, a holding plate 34 and a positioning rod 33. The holding plate 34 is fixed to the mounting platform 1, and the third slider 31 is longitudinally movable toward the holding plate 34 on the mounting platform 1.

[0031] Specifically, the longitudinal clamping mechanism 3 further includes a third slide rail 32 , which is fixed to the mounting platform 1 . The third slide rail 32 is movably provided with a third slider 31 and is equipped with a third cylinder 35 for driving the third slider 31 .

[0032] The third slider 31 is secured to a positioning rod 33. The positioning rod 33 is secured with a latch 332 and a stepped surface 331. The latch 332 has a punched groove 3321. A portion of the outer surface of the punched groove 3321 mates with the inner surface of the positioning groove a3. The holding plate 34 and stepped surface 331 respectively hold the ends of the semi-finished product a-1, while the latch 332 is inserted into the beveled cutout a2 of the semi-finished product a-1.

[0033] Preferably, the third slider 31 and the positioning rod 33 are, but not limited to, integrally formed.

[0034] Preferably, the positioning rod 33 and the latch pin 332 include but are not limited to being integrally formed.

[0035] Preferably, the free end of the latch 332 is chamfered to facilitate easier insertion of the latch 332 into the oblique cut a2.

[0036] like Figure 2 、 Figure 3 and Figure 5 As shown, when in use, after the semi-finished product a-1 is horizontally positioned, the third slide 31 is driven by the third cylinder 35 to move longitudinally, so that the pin 332 is inserted into the interior of the semi-finished product a-1 from the oblique cut a2, so that the step surface 331 is supported on the T-shaped plate a1 of the semi-finished product a-1, and the other end of the semi-finished product a-1 is supported on the supporting plate 34, thereby completing the longitudinal positioning of the semi-finished product a-1.

[0037] like Figure 3 and Figure 5As shown, the lateral holding assembly 4 includes a fourth slider 41, which is laterally movably disposed on the mounting platform 1. The fourth slider 41 has a first holding surface 411, which is a semicircular groove for simultaneously holding the surface of the semi-finished product a-1 and the positioning rod 33.

[0038] Specifically, the mounting platform 1 is fixedly provided with a first slide rail 405 , the first slide rail 405 is movably provided with a fourth slider 41 , and is equipped with a fourth cylinder 42 for driving the fourth slider 41 .

[0039] like Figure 3 and Figure 5 As shown, during use, after the finished product a-1 is longitudinally positioned, the fourth slider 41 is driven longitudinally by the fourth cylinder 42 so as to simultaneously support the surfaces of the semi-finished product a-1 and the positioning rod 33. In other words, the first supporting surface 411, the semi-finished product a-1, and the positioning rod 33 have the same diameter. A portion of the first supporting surface 411 is in close contact with the outer surface of the semi-finished product a-1, while another portion is in close contact with the outer surface of the semi-finished product a-1. At this time, the interior of the semi-finished product a-1 is embedded with the latch 332, and the fourth slider 41 is used to support the semi-finished product a-1 and the positioning rod 33 (including the latch 332) laterally. The fourth slider 41 withstands the forces of the stamping process, preventing the semi-finished product a-1 from undergoing unnecessary deformation, such as bending, during stamping. At the same time, the fourth slider 41 can also effectively protect the positioning rod 33 (including the latch 332) during the stamping process.

[0040] like Figure 2 、 Figure 3 and Figure 6 As shown, the stamping assembly 5 includes a fifth slider 51 and a stamping head 53. The fifth slider 51 is longitudinally movably disposed on the mounting platform 1. The fifth slider 51 is fixed with the stamping head 53, and the stamping head 53 is provided with a stamping protrusion 5321. The outer surface of the stamping protrusion 5321 fits with the outer surface of the positioning groove a3.

[0041] Specifically, the first slide rail 405 is movably provided with a fifth slider 51 and equipped with a fifth cylinder 52 for driving the fifth slider 51. In other words, the fifth slider 51 and the fourth slider 41 share a slide rail, ie, the first slide rail 405.

[0042] As an example, the fifth slider 51 and the punch head 53 are formed integrally, including but not limited to being formed integrally. The punch head 53 is provided with a punching protrusion 5321 in an integral manner.

[0043] Preferably, the punch head 53 is provided with a second holding surface 532, and the second holding surface 532 is opposite to the first holding surface 411, and the second holding surface 532 is provided with a punching protrusion 5321. More precisely, the second holding surface 532 and the first holding surface 411 that hold the semi-finished product a-1 are opposite to each other and cooperate with each other.

[0044] Preferably, the first slide rail 405 is provided with a placement platform 212 for supporting the semi-finished product a-1. The number of placement platforms 212 on the first slide rail 405 is one, plus two placement platforms 212 on the first slide rail 405, for a total of three placement platforms 212, so as to stably place the semi-finished product a-1.

[0045] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 and Figure 6 As shown, during use, while or after lateral support is being performed, the fifth cylinder 52 drives the fifth slide 51 to move, and the punch head 53 cooperates with the punching groove 3321 to punch out the positioning groove a3 in the semi-finished product a-1, thereby producing the semi-finished product a-2. During the punching process, the punching groove 3321 serves to avoid and assist in shaping.

[0046] The above is only a specific implementation method of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
