Problems solved by technology
Aiming at the fact that when the metal cylinder has a gourd-shaped lower opening and there is no straight section, it is difficult for the screw ring to be tightened on the metal cylinder through interference fit, which will cause the outer bottom to be unable to be tightened. The invention provides a bottom inner wall of the metal cylinder. Device and technology for upper processing notch

A device and process for processing notches on the inner wall of the bottom of a metal cylinder. The device includes: a punching machine and a mold. On the platform of the punching machine, the lower mold base is equipped with a die, a workpiece positioning ring, and a guide sleeve. The metal cylinder body is fixed in the die through the workpiece positioning ring. The punch is installed at the bottom of the upper die base. Compression spring, the top of the ejector pin is against the bottom of the upper mold base. The process includes four steps, the positioning of the die and the workpiece positioning ring; the positioning of the workpiece; stamping; and the reset of the mold. The invention has the advantage that the metal cylinder body with the anti-rotation notch processed by the device overcomes the defect that it is easy to rotate in the past, and solves the cooperation between the lower part and the screw ring when the cylinder body is in the shape of an inverted trumpet. The structure of this device is simple and reliable, and it is easy to operate. It adopts stamping from the inside of the metal cylinder to the outside, which subtly improves the shortcoming of poor strength of the die.
Description
technical field [0001] The invention relates to a manufacturing equipment and process of a thermal insulation container, in particular to a device and a process for processing notches on the inner wall of the bottom of a metal cylinder body. Background technique [0002] At present, in the products of the metal shell body of the thermal insulation container, there is no anti-rotation design between the bottom of the metal body and the plastic screw ring, and the interference between the screw ring and the body is used to achieve the anti-rotation function. When it is in the shape of a trumpet, the screw ring will not be able to stop the rotation because the screw ring will move upwards. The method generally used in the industry is: 1. Design a ring groove on the outer wall of the screw ring to offset the wall at the bottom of the barrel to limit the rotation. The screw ring moves upward, but because the diameter of the bottom wall of the cylinder body and the manufacturing t...
