DETAILED DESCRIPTION OF THE INVENTION

[0040] In FIG. 1, the positive extractor (10) maintaining press by arriving upper head connection block (50) of bolt shaft (62) belonging to bolt draft with the force applied on y-axis, bolt die module (A) having the mould connection block (20) providing connection of mentioned positive extractor (10) are figured. In the aforementioned y-axis, die connection block (20) centered die hole (32) owning die (30) and brand die (42) in various forms centered in the upper head connection block (50) maintaining burr-free production while forming and ensuring the shape of head in different forms by the pressed bolt shaft (62). Aforementioned die (30) and different formed head die (40) located between different forms of brand dies(42) and aforementioned different forms of brand die (42) bolt die module (A) fixing different head formed brand die houses (41) are available. Also, housing level (31) is available for centering the aforementioned die (30) with the die connection block (20).

[0041] FIG. 1 indicates the perspective view of the bolt die module (A). Positive extractor (10) is available at the bottom of figure that enables forming of the bolt head (61) by supporting the bolt (60). Positive extractor (10) enters into the die connection (20) and supports the bolt (60). Aforementioned die connection block (60) ensures inter-connection of aforementioned positive extractor (10) and the die (10). Aforementioned die connection block (20) prevents unwanted movement of the die (30) with the pressure applied by the positive extractor (10) encapsulated in the die (30) with the connection flange (21). Aforementioned connection flange (21) is fixed to aforementioned die connection block (20) via fixation elements (211). As indicated above, the die (30) holding the bolt shaft (62) belonging to the bolt (60) within the connection flange (21) and die connection block (20). Head die (40) having a design that prevents burr forming while forming bolt head (61) in different head forms is available on the die (30). Head die in different forms (40) consists of different forms of brand die (42) shaping the bolt head (61) in different forms and brand die house (41) in different head forms fixing aforementioned different forms of brand die (42) to the bolt die module (A).

[0042] FIG. 1 shows the upper head connection block (50) at the upper section. Upper head connection block (50) is fixed via inter-connection elements (51) via different forms of head die (40). Upper head connection block (50) is shaped as the different forms of brand die (42) of bolt (60) with applied press force since different forms of brand dies (42) are located on the upper section.

[0043] The bolt die module (A) working principle is as follows.

[0044] When the operation is initiated, the different forms of brand die (42) connected to bolt die module (A) is moved with downwards direction (Y) and one end is encapsulated along the downward movement direction (Y) between the upper head connection block (50) and one end with the bolt shaft (62) positive extractor (10) by heating to the forging heat. Bolt head (61) of the bolt (60) with heated one end between different forms of head die (40) and different forms of brand die (42) shall be forged and formed as burr-free. Through movement of upper head connection block (50) towards backwards direction (Y+), head (61) shall be taken out from the die (30) as burr free and left in the case for cooling down.

[0045] Production steps burr-free bolt (60) containing the of Bolt die module (A) are as given below. [0046] placing induction device head side heated steel stick pieces within the die hole (32) having the same diameter with the heated steel part at the middle of lower die (30) connected to friction press table, [0047] successively placing steel stick centering die and different forms of head die (40) as tight-fit in the lower die (30), [0048] when the operation is initiated, different forms of head dies (40) connected to upper table of the press is moved downwards and encapsulating heated stick with one end heated to forging temperature with ongoing downwards movement between lower die and upper die, [0049] forming the head die (30) and steel stick with heated one end between different forms of head die (40) and forging as the burr-free, [0050] upon back upwards movement of the head die (30), taking out the head forged bolt as burr-free from the die housing and leaving for cooling down.
