Description

Forging dies for generator pulleys Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a forging die for a generator pulley. Background Technology

[0002] Generator pulleys, belonging to the disc / hub category, are generally relatively large in size and are primarily manufactured using casting and forging processes. Larger pulleys are typically designed for casting, usually using cast iron (due to its superior casting properties), and rarely cast steel (due to its poor casting properties). Smaller pulleys can be designed for forging, using steel as the material. Pulleys are mainly used for long-distance power transmission, such as in small diesel engines, agricultural vehicles, tractors, automobiles, mining machinery, machining equipment, textile machinery, packaging machinery, lathes, forging machines, power transmission in some low-horsepower motorcycles, power transmission in agricultural machinery, air compressors, reducers, speed reducers, generators, cotton gins, etc. Forging dies are generally used in the manufacturing process of generator pulleys.

[0003] However, in the existing technology, during the manufacturing process of generator pulleys using forging dies for generator pulleys, it has been found that after some generator pulleys are forged, the forged generator pulleys are embedded inside the die, making it difficult to remove them.

[0004] To address this issue, a forging die for generator pulleys was proposed. Summary of the Invention

The top of each of the two limit blocks has a moving groove, and two handles are fixedly connected to both sides inside the two moving grooves. The other side of each of the two limit blocks has a second limit groove.

[0010] In a preferred embodiment, the fixed feeding assembly includes two forward and reverse motors and two limiting plates.

Connecting plates two on both sides of the forging head are connected to connecting plate one using bolts and nuts. By manipulating the actuating block, the limiting plate and limiting rod connected to the actuating block move along the limiting post to the other end of the limiting post. The spring is deformed by the compression of the limiting plate. A suitable mold assembly is placed inside the mold placement groove, and the actuating block is released. Under the action of the spring force, the limiting rod moves to the other end of the limiting post, and one end of the limiting rod is embedded inside the limiting groove two, fixing the mold assembly. The material to be forged is placed inside the mold groove. The extension length of the electric cylinder is set and activated via an external controller. The electric cylinder extends downwards, driving the forging head to move downwards and forge the material inside the mold slot. After forging, the external controller starts the forward and reverse motors, whose outputs drive the bidirectional threaded rod to rotate. The two base plates move to opposite sides. The external controller then starts the electric cylinder, which drives the forging head downwards. The forging head moves into the mold slot and squeezes the forged generator pulley downwards, causing it to fall into the unloading chute and exit from the other end. This design allows for the replacement of mold components and forging heads according to the specifications of the forged generator pulley, enabling forging of different specifications of generator pulleys and facilitating the removal of the forged generator pulley.

The limiting groove 206 and the limiting rod 306 cooperate to limit the up and down movement of the mold assembly 2.

[0036] In one embodiment, the bottoms of two forward and reverse motors 301 are fixedly connected to the surfaces of two motor plates 101. The surfaces of both ends of two bidirectional threaded rods 302 are embedded in the interior of four bearing holes 106 via bearings.

The other ends of two springs 307 are fixedly connected to one end of the interior of the two limiting plate movable grooves 113. The interior of the two springs 307 is movably sleeved on the surface of two limiting posts 115. The surfaces of the two limiting rods 306 are movably embedded in the interior of the two limiting grooves 206.

[0037] Specifically: the forward and reverse motor 301 is fixed to the surface of the motor plate 101 to prevent the forward and reverse motor 301 from shaking during operation and affecting the normal use of the mold; the movable base plate 303 is always partially located at the bottom of the limiting groove 103 to prevent the bottom of the mold assembly 2 from losing support and falling; after the base plate 303 is moved to both sides, the bottom of the mold groove 202 is completely open without the obstruction of the base plate 303.

[0038] Working principle: The generator pulley is connected to an external power supply device using a forging die. The external power supply device is electrically connected to the forward and reverse motors 301 and provides power. An external controller is electrically connected to the forward and reverse motors 301 and controls them together. In the initial state, the two base plates 303 are in a close-fitting position on the inside. According to the specifications of the generator pulley to be forged, select the corresponding mold assembly 2 and forging head 118. Connect the connecting plates 117 and 116 on both sides of the surface of the forging head 118 with bolts and nuts. By bending the actuating block 305, the limiting plate 304 and the limiting rod 306 connected to the actuating block 305 move along the limiting post 115 to the other end of the limiting post 115. The spring 307 is deformed by the compression of the limiting plate 304. The appropriate mold assembly 2 is placed inside the mold placement groove 102 and the actuating block 305 is released. Under the action of the elastic force of the spring 307, the limiting rod 306 moves to the other end of the limiting post 115, and the surface of one end of the limiting rod 306 is embedded in the inside of the limiting groove 206. The mold assembly 2 is fixed, and the material to be forged is placed inside the mold groove 202. The extension length of the electric cylinder 109 is set by the external controller and the electric cylinder 109 is started. The electric cylinder 109 extends downward and drives the forging head 118 to move downward to forge the material inside the mold groove 202. After forging is completed, the positive and negative motor 301 is started by the external controller. The output end of the positive and negative motor 301 drives the bidirectional threaded rod 302 to rotate, and the two base plates 303 move to the sides. The electric cylinder 109 is started by the external controller and drives the forging head 118 to move downward. The forging head 118 moves into the mold groove 202 and squeezes the forged generator pulley downward and falls into the unloading groove 105. It falls out from the other end of the unloading groove 105. This design allows the mold assembly 2 and the forging head 118 to be replaced according to the specifications of the forged generator pulley. It can forge generator pulleys of different specifications and facilitates the removal of the forged generator pulley.
