Description

Technical Field

[0001] This utility model belongs to the field of bucket tooth forging, and specifically relates to a continuous bucket tooth forging device. Background Technology

[0002] Continuous forging of bucket teeth utilizes forging machinery to apply continuous and uniform pressure to special metal billets, causing plastic deformation at high temperatures to obtain bucket teeth with specific mechanical properties and shapes. This method can refine the grains in the forgings, improve the internal structure of the material, and enhance the mechanical properties, wear resistance, and service life of the bucket teeth. Traditionally, when stamping bucket teeth, the formed bucket teeth need to be manually removed, and then the stamping die and mold need to be cooled and cleaned. These steps are very wasteful and time-consuming, and require two people to operate: one to load and unload the material, and the other to cool and clean the mold. Utility Model Content

The demolding device 5 includes a tail shearing plate 52, a tail forming plate 53, a stamping support base 55, a telescopic cylinder 56, a push plate 57, and a support push column 58. Lifting cylinders 51 and fixing frames 54 are respectively arranged on both sides of the stamping female die 4. The lifting cylinder 51 and the fixed frame 54 are connected to the stamping base 1. The piston cylinder of the lifting cylinder 51 is connected to the tail shearing plate 52. The tail forming plate 53 is connected to the tail shearing plate 52. The stamping support 55 and the telescopic cylinder 56 are mounted on the fixed frame 54. The piston rod of the telescopic cylinder 56 is connected to the push plate 57. Several support push columns 58 are connected to the push plate 57, with one end passing through the stamping support 55 and cooperating with the tail shearing plate 52. The tail forming plate 53 has a tail forming hole 59, and the tail shearing plate 52 has a shearing hole 510. The trimming device 6 includes... The device includes a displacement fixing frame 61, a displacement cylinder 62, a displacement frame 63, a spring 64, a shearing blade 65, a pressure plate 66, and guide posts 67. The displacement fixing frame 61 is connected at both ends to two stamping support seats 55. The displacement cylinder 62 is connected to the displacement fixing frame 61, and its piston rod is connected to the displacement frame 63. The displacement frame 63 is slidably connected at both ends to the two stamping support seats 55. The shearing blade 65 is connected to the pressure plate 66. Several guide posts 67 have one end connected to the pressure plate 66 and the other end passing through the displacement frame 63. The spring 64 is sleeved on the guide posts 67. The shearing blade 65 and the pressure plate 66 are equipped with… It has a clearance groove for inserting the stamping die 3; several stripper columns are connected to the tail edge forming plate 53, and stripper springs are sleeved on the stripper columns and one end passes through the tail edge shearing plate 52; it includes air nozzles, high-pressure air pipes and water pipes, and air nozzles are provided on both the upper and lower sides of the displacement frame 63. The air nozzles are connected to the high-pressure air pipes, and the water pipes are connected to the high-pressure air pipes.

[0021] The excess material from the bucket teeth is formed into a tail edge through the tail edge forming hole 59. After the bucket teeth are continuously stamped and shaped, the tail edge shearing plate 52 and the tail edge forming plate 53 are raised by the lifting cylinder 51. The rise of the tail edge shearing plate 52 will cause the tail edge of the bucket teeth and the bucket teeth to rise together.

The movement causes the shearing blade 65 to move above the tail shear plate 52. Then, the stamping head 2 drives the stamping die 3 to insert into the clearance groove, while simultaneously pushing the pressure plate 66 downward. The pressure plate 66 drives the shearing blade 65 to engage with the shearing hole 510 on the tail shear plate 52 to separate the bucket teeth from the tail edge of the bucket teeth. The stamped bucket teeth fall onto the discharge hopper 68 and slide out. After the stamping head 2 rises, the tail forming plate 53 is lifted by the stripping spring to facilitate the removal of the stamped tail edge. The guide post 67 engages with the guide hole or guide sleeve to ensure the accuracy of the shearing blade 65 and the shearing hole 510 during stamping. High-pressure gas and cooling water mist are discharged through the air nozzle. When the high-pressure gas is discharged, the water discharged along with it is blown away to achieve a cooling effect.
