Abstract:
An apparatus for continuously producing jingling bells, comprising an upper mold assembly (1) and a lower mold assembly (19), the upper mold assembly (1) comprising:an upper mold seat (2) having a front section and a rear section,a front punch board (4) fixed to the front section of the upper mold seat, a shallow punch pin (6), a deep punch pin (7), a tie-piece punch pin (8), and a wings-punch pin (9) being mounted to the front punch board (4) in sequence, anda rear punch board (10) fixed to the rear section of the upper mold seat, a straightening punch pin (11), a jingling member cutter (12), a closing punch pin (13), and an ejection pin (15) being mounted to the rear punch board (10) in sequence,the lower mold assembly (19) comprising:a lower mold seat (20) including a front section, a rear section, an ejection notch (47), and a hole (49),a first mold plate (23), a second mold plate (24), and a third mold plate (25) being securely mounted to the front section of the lower mold seat (2) and stacked from top to bottom in sequence, the first mold plate (23) including a shallow groove (26), a deep groove (27), a tie-piece punch groove (28), and a wings-punch hole (29) arranged in sequence in an upper side thereof and respectively located below the shallow punch pin (6), the deep punch pin (7), the tie-piece punch pin (8), and the wings-punch pin (9), the first mold plate (23) including a first end that defines a material inlet (30) and a second end that defines a waste material outlet (31), the second mold plate (24) including a material groove (33) in an upper side thereof and below the wings-punch hole (29) in the first mold plate (23),a fourth mold plate (34), a fifth mold plate (35), a sixth mold plate (36), and a seventh mold plate (37) being securely mounted to the rear section of the lower mold seat (20) and stacked from top to bottom in sequence, the fourth mold plate (34) and the sixth mold plate (36) including first aligned holes (39a and 39b) that are aligned with the closing punch pin (11), the fifth mold plate (35) including a track (44) aligned with the first aligned holes (39a and 39b) of the fourth mold plate (34) and the sixth mold plate (36), the fourth mold plate (34), the fifth mold plate (35), and the sixth mold plate (36) further including second aligned holes (40a, 40c, and 40b) that are aligned with the cutter (12), the fourth mold plate (34) further including a transverse hole (41) communicated with the second aligned hole of the fourth mold plate hole (40a), an iron wire (G) being fed to the first and second aligned holes hole (40a) via the transverse hole (41), the seventh mold plate (37) including an arcuate recess (46) below the holes (39a, 39b, 40a, 40b, and 40c),a rotating wheel (50) rotatably mounted to the lower mold seat (20) and including a plurality of annularly disposed closing holes (52), each said closing hole (52) receiving a closing sleeve (53) therein, and some of the closing holes (52) being located in the arcuate recess (46) of he seventh mold plate (37),a disc (51) secured between the rotating wheel (50) and the lower mold seat (20) and including a through-hole (57) and an ejection hole (58), each of the through hole (57) and the ejection hole (58) being aligned with an associated said closing hole (52) in the rotating wheel (50), andan anchor member (63) received in the hole (49) of the lower mold seat (20) and the through-hole (57) in the disc (51),the upper mold seat (2) being reciprocatingly movable through an upward stroke and a downward stroke relative to the lower mold seat (19),whereby a material web (5a) is fed to pass through the upper side of the first mold plate (23) via the material inlet (30) and exits via the waste material outlet (31), and in the downward stroke of the upper mold seat (2): (a) the shallow punch pin (6) punches the material web (5a) to form a shallow depression (A); (b) the deep punch pin (7) punches the shallow depression (A) of the material web (5a) formed in a previous punching procedure to form a deep depression (B); (c) the tie-piece punch pin (8) punches the deep depression (B) of the material web (5a) formed in the previous punching procedure to form a tie-piece (T) in the deep depression (C); (d) the wings-punch pin (9) punches the deep depression (C) of the material web (5a) formed in the previous punching procedure to form a star-shape semi-product (D) for a jingling bell, the star-shape semi-product (D) separates from the material web (5a) and then falls on the material path (33) of the second mold plate (24), further comprising:means for displacing the star-shape semi-product (D) in the material path (33) of the second mold plate (24) into the track (44) of the fifth mold plate (35) during the upward stroke of the upper mold seat (2), andmeans for driving the rotating wheel (50) to rotate along a direction by a distance equal to a distance between the centers of two adjacent said closing holes (52) during the upward stroke of the upper mold seat (2),whereby in the downward stroke of the upper mold seat (2): (e) the straightening punch pin (11) punches the star-shape semi-product (D) formed in the previous punching procedure to form a flower-like semi-product (E) that then falls into the closing sleeve (53) in the associated said closing hole (52) via the first aligned hole (39b) of the sixth mold plate (36); (f) the rotating wheel (50) is rotated along the rotational the direction by said distance such that the semi-product (E) formed in the previous punching procedure is shifted to a position below the second aligned hole (40b) of the sixth mold plate (36); (g) the cutter (6) cuts the iron wire (G) to thereby form a jingling member (H) that then falls into flower-like semi-product (E) via the second aligned holes of the fifth and sixth mold plates (40b and 40c); (h) the flower-like semi-product (E) with the jingling member (H) formed in the previous punching procedure is shifted to a position above the through-hole (57) of the disc (51) during the rotational movement of the rotating wheel (50); (i) the closing punch pin (13) punches and thus closes the flower-like semi-product (E) with the jingling member (H) therein to thereby form a jingling bell (F); (j) the jingling bell (57) formed in the previous punching procedure is shifted to a position above the ejection hole (58) of the disc (51) during the rotational movement of the rotating wheel; and (k) the ejecting pin (15) ejects the jingling bell (F) in the associated closing hole (52) above the ejection hole (58) out of the rotating wheel (50) to thereby eject the jingling bell (F) via the ejection notch (47).
