[0042] The transverse material pulling mechanism 20 is used to drive the main material belt 501 to move laterally. The main material belt 501 is connected to the main body 51 with terminals 50. There are multiple main bodies 51 arranged side by side at intervals. The transverse material pulling mechanism 20 is set on the base 10. The specific structure and working principle of the transverse material pulling mechanism 20 are existing technologies. The specific structure and working principle of the transverse material pulling mechanism 20 will not be described in detail here.

[0043] The longitudinal pulling mechanism 30 is used to drive the auxiliary material belt 502 to move longitudinally. The auxiliary material belt 502 is connected to the housing 52 of the terminal 50. There are multiple housings 52 arranged side by side at intervals. The longitudinal pulling mechanism 30 is set on the base 10. The specific structure and working principle of the longitudinal pulling mechanism 30 are existing technologies. The specific structure and working principle of the longitudinal pulling mechanism 30 will not be described in detail here.

[0044] The stamping die 40 is used to stamp and rivet the outer shell 52 onto the main body 51. A cross station 11 is formed on the base 10 at the intersection of the main material strip 501 and the auxiliary material strip 502. The stamping die 40 is mounted on the base 10 and located on the cross station 11. The stamping die 40 includes a lower die 41 and an upper die 42. Specifically:

[0045] The lower mold 41 includes a lower mold body 411 and two side mold bodies 412, which are symmetrically arranged on the left and right sides of the lower mold body 411. Guide grooves 401 are formed between the inner upper sides of the two side mold bodies 412 and the left and right upper sides of the lower mold body 411, respectively. In this embodiment, the two sides of the guide groove 401 have a first inner inclined surface 4011 and a first outer inclined surface 4012, respectively.

[0046] The upper mold 42 is movably positioned directly above the lower mold 41. The upper mold 42 includes an upper mold body 421 and two forming swing arms 422. The upper mold body 421 has two downward-facing receiving grooves 402, which are symmetrically arranged. The two forming swing arms 422 are also symmetrically arranged and can swing left and right within the receiving grooves 402. The lower ends of the two forming swing arms 422 extend downward from the receiving grooves 402 and are detachably engaged with the two guide grooves 401. In this embodiment, a forming positioning cavity 403 is recessed at the center of the top surface of the upper mold body 421. This forming positioning cavity 403 is used for inserting and forming the main body 51 and the outer shell 52. Furthermore, the receiving groove 402 penetrates the front and rear sides of the upper mold body 421, and the top of the receiving groove 402 has a shaft hole 4021. Correspondingly, the upper end of the forming swing arm 422 has a shaft portion 4221, which is hinged to the shaft hole 4021. The structure is simple and easy to assemble. In addition, the lower end of the forming swing arm 422 has a guide portion 4222, which is detachably engaged with the guide groove 401. The guide portion 4222 has a second inner inclined surface 4013 and a second outer inclined surface 4014 on both sides. The second inner inclined surface 4013 engages with the first inner inclined surface 4011, and the second outer inclined surface 4014 engages with the first outer inclined surface 4012, so that the guide portions 4222 of the two forming swing arms 422 can open or close relative to each other. Furthermore, through holes 404 are formed on the left and right sides of the upper mold body 421, connecting the two receiving grooves 402. A spring member 423 is installed in the through hole 404. Positioning recesses 405 are recessed on the inner sides of both forming arms 422. The two ends of the spring member 423 are respectively inserted into the two positioning recesses 405, causing the two forming arms 422 to open apart. Further, the upper mold 42 also includes a separating punch 424, which is movably positioned relative to the upper mold body 421. The separating punch 424 is located on the rear side of the upper mold body 421, allowing the terminal 50 to sever the connection between the outer shell 52 and the auxiliary material strip 502 after forming is completed.

[0047] The working principle of this embodiment is described in detail below:

[0048] First, install this invention onto the punch press and connect the upper die 42 to the lifting mechanism of the punch press. Next, start the equipment. The transverse pulling mechanism 20 moves the main material strip 501 laterally, while the longitudinal pulling mechanism 30 moves the auxiliary material strip 502 longitudinally. When the outer shell 52 moves with the auxiliary material strip 502 to directly below the main body 51, the transverse pulling mechanism 20 and the longitudinal pulling mechanism 30 stop working. Then, activate the lifting mechanism of the punch press, which moves the upper die 42 downwards to close with the lower die 41. During the downward movement of the upper die 42, the center of the bottom surface of the upper die body 421 first causes the outer shell 52 to move downwards and fit onto the main body 51. Then, the two guides... The guide portion 4222 is inserted downwards into the two guide grooves 401 respectively. Under the guidance of the inclined surface, the two forming swing arms 422 close and act on the left and right sides of the outer shell 52 respectively, so that the outer shell 52 is riveted and fixed to the main body 51. After the mold is closed, the riveting and forming is completed, thus forming a complete terminal 50. Then, the separating punch 424 continues to move downwards to cut off the connection between the outer shell 52 and the auxiliary material strip 502. At this time, the terminal 50 is still connected to the main material strip 501. Then, the lifting mechanism of the punch press is activated, and the lifting mechanism drives the upper mold 42 to move upwards and open with the lower mold 41. After the mold is opened, the above actions are repeated to rivet the next terminal 50.

[0049] The key design feature of this invention is that by using a transverse material pulling mechanism to drive the main material strip to move laterally, and a longitudinal material pulling mechanism to drive the secondary material strip to move longitudinally, and by using a stamping die to stamp and rivet the outer shell onto the main body, the automatic forming and riveting of the main body and the outer shell is achieved, which effectively improves production efficiency, reduces manpower consumption, and also reduces labor costs, bringing convenience to manufacturing enterprises.

[0050] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
