[0047] The connecting assembly includes: a square frame 40, a slide groove 41, a fixing plate 42, a slide rod 43, a positioning circular plate 44, a positioning circular groove 45, a spring 46, an iron plate 47, and an electromagnet 48;

[0048] The outer sides of the first mold 20, the second mold 21 and the third mold 22 are all fixedly installed with a square frame 40, and one end of the square rod 33 is inserted into the square frame 40, and the cross-sectional shape and size of the square rod 33 match the cross-sectional shape and size of the inner cavity of the square frame 40. The inner cavity of the square frame 40 is provided with a plurality of slide grooves 41, and the fixed plate 42 is fixedly installed in the slide groove 41. The slide rod 43 is slidably connected in the fixed plate 42. The positioning circular plate 44 is fixedly installed on one end of the slide rod 43. One end of the square rod 33 is provided with a plurality of positioning circular grooves 45, and the positioning circular grooves 45 are provided in the inner cavity of the square frame 40. Plate 44 is inserted in the positioning circular groove 45, iron plate 47 is fixedly mounted on the other end of the slide rod 43, electromagnet 48 is fixedly mounted in the slide groove 41, and electromagnet 48 can adsorb iron plate 47, a spring 46 is sleeved on the slide rod 43, and the two ends of the spring 46 are respectively fixedly connected to the fixed plate 42 and the positioning circular plate 44, wherein the suction force of the electromagnet 48 and the elastic force of the spring 46 can be adjusted according to needs, as long as it is ensured that when the electromagnet 48 is started, the iron plate 47 can be moved toward the electromagnet 48.

[0049] Working principle: Place the hardware to be stamped on the lower die, and then use the upper die to stamp the hardware to be stamped. After the hardware is stamped, first restore the upper die to its original position, and then use the servo motor 35 to rotate the screw 31. When the screw 31 rotates, the slider 32 and its square rod 33 will move the first die 20, the second die 21 and the third die 22 outward a short distance (the distance can be set according to needs, as long as it does not affect the later use of the hardware) to be able to stretch the hardware outward. After that, the servo motor 35 will reverse the screw 31 to make the first die 20, the second die 21 and the third die 22 move closer to each other and return to their original position, and then the hardware can be taken out.

[0050] Among them, when it is necessary to install the square rod 33 and the lower mold, the iron plate 47 is first adsorbed by the electromagnet 48. At this time, the spring 46 will be in a state, and the positioning circular plate 44 will be in the slide groove 41. Then one end of the square rod 33 can be inserted into the square frame 40. After it is fully inserted, its positioning circular groove 45 and the positioning circular plate 44 will be aligned. At this time, the electromagnet 48 can be turned off to make the positioning circular plate 44 inserted in the positioning circular groove 45 under the action of the spring 46. At this point, the lower mold can be installed; in this process, only one end of the square rod 33 needs to be inserted into the square frame 40, without too many steps, which is convenient for personnel to disassemble and assemble the lower mold.

[0051] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
