And possess in upper die (120): increased pressure board (121), it is to the pressurization above of first time products formed (10B); 4th drift (122), its downward through increased pressure board (121) also carries out lifting running, inserts the groove (14A) above first time products formed (10B).
By means of formation as above, the present invention is after first time products formed (10B) is placed in placement portion (111), upper die (120) carries out decline running, if by means of increased pressure board (121), by the exert pressure of about 160 tons above first time products formed (10B), so, while placement portion (111) decline, second, three drifts (113, 114) upper part raises up towards placement portion (111), at the rounded portions (12A of first time products formed (10B), 12B) form four chamfered groove (15A respectively, 15B), meanwhile, by means of the first drift (112), the size of forging the groove (14B) formed in step (S20) in first time is shaping greatlyr.
In addition, at increased pressure board (121) in the process of pressurizeing above first time products formed (10B), 4th drift (122) through increased pressure board (121) and protruding downwards, thus, at the groove (14A) formed above first time products formed (10B) also as the groove (14B) below, its size is shaping greatlyr, and the second time products formed (10C) so manufactured is transplanted on trimming described later and punching unit (200).
D. trimming and punching step (S40)
Trimming and punching step (S40) are as shown in figs. 7 a and 7b, utilize trimming and punching unit (200), to block along the surrounding of second time products formed (10C) and while removing, to described groove (14A, 14B) carry out punching processing, manufacture third time products formed (10D), now, trimming of the present invention and punching unit (200) are as shown in Figure 8, comprise: lower mould (210), it possesses confession second time products formed (10C) and lays and the placement portion (211) carrying out being elevated running; Upper die (220), it is positioned at the top of lower mould (210) and carries out lifting running.
And possess punching projection (212) in lower mould (210), the middle body of its through placement portion (211) is installed; In upper die (220), possess increased pressure board (221), pressurize in its top to second time products formed (10C), is formed with the patchhole (221A) of the top insertion for punching projection (212).
By means of formation as above, the present invention is after second time products formed (10C) is placed in the placement portion (211) of lower mould (210), the running if the increased pressure board (221) of upper die (220) declines, pressurizeed in the top of second time products formed (10C), so, while placement portion (211) decline running, the through placement portion, upper part (211) of punching projection (212), protrude to top, thus, punching projection (212) connects and the through groove (14A formed respectively in the top and bottom of second time products formed (10C), 14B), thus, the middle body being manufactured on second time products formed (10C) is formed with through hole (14C), along rounded portions (12A, 12B) with curved face part (13A, the material press section (B) that 13B) surrounding is formed is truncated and the third time products formed (10D) removed.
And the third time products formed (10D) of manufacture, after T6 heat treatment, is transplanted on machining step (S50) described later.
Wherein, T6 heat treatment means cooling after solution heat treatment and does not implement the state of cold rolling processing, and this T6 heat treatment belongs to known content, thus omits and is described in more detail.
E. machining step (S50)
Machining step (S50) utilizes the machining cells such as tapping, milling, lathe, CNC, at the four chamfered groove (15A of third time products formed (10D), 15B) part is communicated with formation intercommunicating pore (H, H'), manufacture manufactured goods (10E), more preferably the manufactured goods (10E) so manufactured, through Surface Machining step (S60), carry out Surface Machining by means of make use of shot-peening (blasting) processing being selected from a certain grinding agent in sand, steel, abrasive material.
On the other hand, manufacturing installation for clutch lever of the present invention comprises: first time forges unit, it is being formed with rectangular shape and the two end portions that side is formed with the raw material (10A) of protuberance (11) above forms rounded portions (12A, 12B), curved face part (the 13A of arc is formed in two sides, 13B), groove (the 14A of both sizings is formed at top and bottom middle body, 14B), first time products formed (10B) is manufactured; Second time forges unit (100), and it forms four chamfered grooves (15A, 15B) respectively below the rounded portions (12A, 12B) of described first time products formed (10B), manufactures second time products formed (10C); Trimming and punching unit (200), it, while blocking along the surrounding of second time products formed (10C), carries out punching processing to groove (14A, 14B), manufactures third time products formed (10D); And machining cell, it forms intercommunicating pore (H, H'), makes it be communicated with four chamfered groove (15A, the 15B) parts of third time products formed (10D), manufactures manufactured goods (10E).
