Description

Technical Field

[0001] The utility model relates to the technical field of forging blank dies, in particular to a gear forging blank die. Background Art

[0002] The gear forging mold is a mold used to produce gear forgings. The mold shapes the metal blank by heating and applying pressure, and finally forms the required gear shape. During the production process, the mold needs to be forged and adjusted many times to ensure that the accuracy and strength of the gear meet the requirements. The gear forging mold is one of the indispensable tools in gear manufacturing. It is a tool used to produce gear forgings. It is crucial to the quality and efficiency of gear manufacturing.

[0003] When using the existing gear forging mold for forging, a large amount of heat is generated during the forging process. If the heat cannot be dissipated in time, the mold will overheat and be damaged. This situation will not only affect the smooth progress of the forging process, but also lead to frequent replacement and maintenance of the mold, thereby increasing production costs.

[0004] Patent document CN212042486U discloses a forging gear die, "including a gear die body and a stamping plate body, a gear die cavity is fixedly provided in the middle of the top of the gear die body, grooves are opened at the four corners of the top of the gear die body, and buffer rods are inserted and connected inside the four grooves, one end of the four buffer rods is respectively fixedly connected to the four corners of the bottom of the stamping plate body, a stamping head is fixedly provided in the middle of the bottom of the stamping plate body, and buffer air bags are fixedly provided at the bottom of the inner cavity of the four grooves. In the utility model, a certain buffering and protective effect is played by the provided buffer air bags and gaskets to avoid excessive impact force during the forging process, causing the gear die body and the stamping plate body to collide with each other, causing damage to the gear die body and the forging blank, and the provided storage trough and collection trough can collect the forged blanks and forging blanks, which is convenient to take and has strong practicality." However, the forging gear die in the above-mentioned public document mainly considers the collection of forged blanks and forging blanks, and does not consider the problem of heat dissipation efficiency through the die. Therefore, it is necessary to develop a gear forging blank die. Utility Model Content

[0029] Working principle: first, when the gear forging blank mold is used to forge the gear, the blank is placed inside the mold body 4, and then the external forging machine applies pressure and knocks the blank, so that the blank is formed inside the mold body 4, which is convenient for forging the gear. Since the blank is forged after heating, the temperature of the mold body 4 will increase during the forging period. The mold body 4 is prone to damage when it is in a high temperature state for a long time. When the gear forging blank mold is shaping the gear, the temperature of the mold body 4 is cooled down, and the fan 7 is operated to generate wind force, and the wind force will enter the inside of the wind collecting groove 8, and then the wind collecting groove 8 cooperates with the input pipe 10 to make the wind force enter the inside of the flow groove 9 to flow, and then when the wind force flows inside the flow groove 9, it will carry the heat flow on the mold body 4. The movement will then cool the die body 4, thereby achieving the purpose of improving the heat dissipation efficiency of the gear forging blank die, thereby improving the service life of the gear forging blank die. The wind flowing inside the flow groove 9 will cooperate with the exhaust head 11 and the connector 15 to make the wind flow into the inside of the hose 14, and then flow into the inside of the annular groove 13. The wind entering the annular groove 13 flows to the outside through the jet hole 16. The telescopic rod 12 will push the annular groove 13 to move. After adjusting the position of the annular groove 13, the jet hole 16 is moved to one side of the support plate 3. The jet hole 16 will make the wind flow to the surface of the support plate 3, and then the debris dropped on the support plate 3 will be cleared, thereby achieving the purpose of automatically clearing the debris, thereby improving the practicability of the gear forging blank die.
