Description

Technical Field

[0001] The utility model relates to the technical field of oil pipe joint processing, and more specifically to a hot forging device for an oil pipe joint blank. Background Art

[0002] Oil pipe joint blank steel is a raw material used to manufacture oil pipe joints, usually unprocessed steel pipes or steel plates. Oil pipe joints are components used to connect oil pipes. They are very common in industrial production and applications. There are many types, including flared pipe joints, ferrule pipe joints, welded pipe joints, etc.

[0003] After searching, the Chinese patent with publication number CN217252508U discloses a forging machine for processing automobile oil pipe joints with high safety. In the cited solution, the panel is fixed by a magnetic rubber pad. During the stamping process of the hydraulic press, due to the huge force, the magnetic rubber pad cannot completely fix the panel due to insufficient tension, which easily causes the panel to shift, resulting in an increase in the defective rate of processing, causing economic losses and being unfavorable for production and use. The panel is limited by a combination of a latch tooth and a positioning tooth. Since the latch tooth and the positioning tooth are rigidly connected, the stability of the position of the slide plate during the stamping process is effectively guaranteed. At the same time, since the first positioning tooth corresponds to the working position of the stamping, the connection between the latch tooth and the first positioning tooth can ensure accurate positioning during position resetting and ensure the stamping quality.

[0004] When the forging device is forging the oil pipe joint, the oil pipe joint blank needs to be heated first to make it plastic. After heating, workers usually clamp the heated oil pipe joint to the forging table for forging. The operation is troublesome, time-consuming and labor-intensive. At the same time, there is a risk of burns to the workers due to the high-temperature oil pipe joint blank, and the safety is low. Utility Model Content
