[0002] A bolt is a cylindrical mechanical part with threads, consisting of two parts: a head and a cylinder with external threads on the screw rod. Bolts are essential in daily life and industrial production and are widely used. A hexagonal bolt is processed through material selection, spheroidizing (softening), descaling, cold drawing, cold forging forming, thread processing, heat treatment, and surface treatment in sequence, and cold forging forming is a very crucial step among them.

Detailed implementation manner

[0027] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with the specific implementation manners.

[0028] As Figures 1-7 shown, a high-efficiency forging device for hexagonal bolts according to the present invention includes a body 1. An exchange mechanism is arranged inside the body 1. A template mechanism is arranged inside the exchange mechanism. A feeding mechanism is arranged on the upper surface of the body 1. A cold forging mechanism is arranged inside the exchange mechanism;

[0029] The exchange mechanism includes a rotating cavity 21. The rotating cavity 21 is opened inside the body 1. A rotating rod 22 is rotatably connected to the cavity wall of the rotating cavity 21 through a bearing. One end of the rotating rod 22 extends into the rotating cavity 21 and is fixedly sleeved with a rotating disk 23. Four receiving grooves 24 are opened on the rotating disk 23. Support cavities 25 are opened at the bottoms of the four receiving grooves 24. A support plate 26 is slidably connected inside the support cavity 25. A mounting groove 27 is opened on the cavity wall of the support cavity 25. A spring 28 is fixedly installed inside the mounting groove 27. One end of the spring 28 extends into the support cavity 25 and is fixedly connected to the support plate 26;

[0030] The template mechanism includes a template 31. The template 31 is inserted into the receiving groove 24. A hexagonal groove 32 is opened on the upper surface of the template 31. A forming groove 33 is opened on the groove wall of the hexagonal groove 32. A through hole 34 is opened at the bottom of the forming groove 33;

[0031] The feeding mechanism includes a moving groove 51. The moving groove 51 is opened on the upper surface of the body 1. A blanking hole 52 is penetrated between the bottom edge of the moving groove 51 and the rotating cavity 21. A driving cavity 53 is penetrated through the bottom of the moving groove 51. The driving cavity 53 is communicated with the rotating cavity 21. Three transmission wheels 54 are rotatably connected between the cavity walls of the driving cavity 53 through a rotating shaft. A transmission belt 55 is connected between the three transmission wheels 54. A rubber roller 56 is fixedly sleeved on one of the rotating shafts. The rubber roller 56 abuts against the rotating disk 23;

[0032] The cold forging mechanism includes a fixed groove 41 which is opened on the wall of the rotating cavity 21. A driving cylinder 42 is fixedly installed on the top wall of the fixed groove 41. The output end of the driving cylinder 42 is movably connected with a piston rod 43. One end of the piston rod 43 extends into the fixed groove 41 and is fixedly connected with a fixed ring 44. A hydraulic press 45 is fixedly installed on the wall of the fixed groove 41. The output end of the hydraulic press 45 is fixedly installed with a forging hammer 46.

[0033] Among them, a driving installation groove 29 is opened on the wall of the rotating cavity 21. A motor 210 is fixedly installed in the driving installation groove 29. The output end of the motor 210 is fixedly installed with a rubber driving wheel 211 through a coupling. The rubber driving wheel 211 abuts against the rotating disc 23. Anti-slip lines are arranged on the outer side wall of the rotating disc 23, and the anti-slip lines on the rotating disc 23 abut against the rubber driving wheel 211 and the rubber roller 56. The motor 210 drives the rotating disc 23 to rotate through the rubber driving wheel 211, and the rotating disc 23 drives the transmission wheel 54 to rotate through the rubber roller 56.

[0034] Among them, a discharge hole 212 is penetrated and opened on the lower wall of the rotating cavity 21. The discharge hole 212 is arranged obliquely, and the orifice of the discharge hole 212 penetrates through the outer wall of the machine body 1. The support plate 26 can be pushed by the spring 28, and the support plate 26 pushes the template 31 to descend and fall into the discharge hole 212 for discharge.

[0035] Among them, the position of the fixed groove 41 corresponds to that of the storage groove 24, and one end of the fixed ring 44 extends into the storage groove 24 and abuts against the template 31, so as to facilitate the alignment of the fixed ring 44 and the forging hammer 46 with the template 31.

[0036] Among them, the fixed ring 44 is sleeved outside the forging hammer 46, and the opening of one end of the fixed ring 44 coincides with the orifice of the hexagonal groove 32 on the template 31. When the forging hammer 46 hammers the workpiece into the hexagonal groove 32 and the forming groove 33, the fixed ring 44 can restrain the workpiece to prevent it from spreading outwards.

[0037] Among them.

[0038] Among them, the template 31 matches the width of the moving groove 51, and the outer diameter of the template 31 matches the inner diameter of the blanking hole 52. When the transmission belt 55 drives, it will drive the template 31 to move parallelly in the moving groove 51 until the template 31 abuts against the wall of the moving groove 51. At this time, the template 31 will coincide with the blanking hole 52, and the template 31 can slide into the rotating cavity 21 through the blanking hole 52 and enter the storage groove 24 when it coincides with the storage groove 24.

[0039] Among them, the bottom end of the template 31 extends into the support cavity 25 and abuts against the outer side wall of the support plate 26. When the support plate 26 abuts against the cavity wall of the support cavity 25, the support plate 26 can support the bottom of the template 31, keeping the template 31 in position, thus facilitating the forging hammer 46 to hammer the workpiece, and hammering the workpiece into the forming groove 33 and the hexagonal groove 32 inside the template 31.

[0040] During use, select the corresponding model of the template 31 according to requirements, then insert the workpiece to be processed into the template 31, and then place several templates 31 in the moving groove 51. The template 31 drops through the blanking hole 52 into the rotating cavity 21 and slides into the storage groove 24; at this time, the motor 210 can be started. The motor 210 drives the rubber driving wheel 211 to rotate, and the rubber driving wheel 211 drives the rotating disk 23 to rotate by abutting against the rotating disk 23. The angle of the rotating disk 23 rotates 90°, driving the template 31 to rotate to a position coinciding with the fixed groove 41. At the same time, the rotating disk 23 drives the driving wheel 54 to rotate by abutting against the rubber roller 56. The driving wheel 54 drives the transmission belt 55 to move, and the transmission belt 55 drives the template 31 on its surface to move, causing the template 31 to be pushed to the position of the blanking hole 52. At this time, the template 31 discharges and drops into the storage groove 24 for backup at the rear; at the same time, first start the driving cylinder 42. The driving cylinder 42 pushes the fixed ring 44 through the piston rod 43, and the fixed ring 44 moves into the storage groove 24 and abuts against it, thus pushing the mold 31 into the storage groove 24. The template 31 pushes the support plate 26 to abut against the support cavity 25, and the support plate 26 supports the template 31 to keep the template 31 in position. At this time, start the hydraulic press 45. The hydraulic press 45 hammers the workpiece to be processed through the forging hammer 46, and then hammers it into the hexagonal groove 32 and the forming groove 33 for forging and forming. After the processing is completed, start the motor 210 again to drive the rotating disk 23 to rotate, so that the blank storage groove 24 moves to the position corresponding to the blanking hole 52 for feeding, and the storage groove 24 with the template 31 moves to the position corresponding to the forging hammer 46 for forging. The processed workpiece and the template 31 after forging move to the position corresponding to the discharge hole 212. At this time, the spring 28 pushes the support plate 26, and the support plate 26 pushes the template 31 to descend and drop into the discharge hole 212 for discharge. Then, the above operations can be repeated for continuous and efficient processing. The discharged template 31 can insert a plug through the through hole 34 to push the workpiece out of the template 31, thus completing the forging and forming of bolts of different models.
