[0002] The fully automatic compact chain ring stamping production equipment has high precision and stability, so it can produce compact chain rings with accurate dimensions and good surface quality. This equipment usually adopts advanced mold technology and stamping process to ensure that the product is not damaged during the stamping process.

[0003] In the existing public documents, the patent announcement number CN118023378A discloses a punching equipment for producing mining chain vertical rings. This technology uses the piston rod of the lifting cylinder to fix the U-shaped bracket. The middle part of the U-shaped bracket is provided with a feeding guide rod that penetrates and connects the clearance port, and the end of the feeding guide rod is provided with a feeding support plate. This invention uses the feeding support plate to cooperate with the intermittently rotating feeding support plate, so that the chain vertical ring is intermittently lifted to complete the punching process, so that the inner ring burr of the chain vertical ring is punched. However, this technology still has the following defects.

During the stamping process, it is difficult to accurately limit the two sides of the compact chain stand. At the same time, the compact chain stand is also very easy to offset during mobile transportation, resulting in the compact chain stand offset problem. In this way, the stamping limit accuracy of the compact chain stand is poor. Therefore, fully automatic compact chain stand production equipment and production methods are required.

When the pressure value of the pressure sensor is the same as the set pressure value, the transmission motor drives the transmission shaft to rotate, and the transmission shaft rotates along the inner wall of the sleeve frame. The upper surface of the outer wall of the chain stand ring forming seat is moved to the stamping position by fixed force and limited position, so as to realize limited precise stamping and greatly improve the stamping accuracy of the compact chain stand ring. 3. The present invention adopts a precise stamping assembly, a positioning sleeve supports the stamping electric cylinder, the stamping electric cylinder pushes the stamping column downward, the stamping column drives the stamping strip downward, and the forging raw material is attached to the outer wall position of the chain stand ring forming seat, so that the forging raw material is compactly formed on the chain stand ring forming seat.
