Description

A semi-automatic head groove edge grinding machine

technical field

The utility model belongs to the technical field of parts manufacturing of pressure vessels, and in particular relates to a semi-automatic head bevel edge grinding machine.

Background technique

The head is one of the important parts of the pressure vessel. The connection weld between the head and the cylinder is very important for the pressure vessel. In order to ensure the quality of the weld, it is necessary to make a bevel on the inside or outside of the head. The beveling process is one of the important processes in the production of pressure vessels.

The currently used head groove processing methods mainly include the following:

Manual flame cutting method: It uses manual flame cutting method to process the groove. The result of this method is that the shape of the groove is irregular, the surface roughness is large, and it cannot meet the requirements of the drawing. It not only has low production efficiency, high cost, and labor The strength is high, and it is difficult to guarantee the quality of the weld, and many welding defects appear, which increases the number of weld repairs. In addition, it has a disadvantage of causing oxidation of the cut surface. Therefore, this processing method is very undesirable.

Semi-automatic flame cutting method: It is implemented by a set of mechanical devices. The device is driven by a motor through a deceleration device to rotate a disc. A ring is set on the disc, and the head is placed on it. However, during use, the biggest inconvenience of this device is that after the head is placed on the seat ring, in order to keep the cut part of the head at an equal distance from the cutting nozzle, it needs to be adjusted and aligned many times during cutting. That is to constantly change the position of the head on the seat ring. Although the processing result is ideal compared with the manual flame cutting method, the irregular shape of the groove and the large roughness of the cutting surface are also its defects.

Vertical lathe processing groove method: it is to process the groove by turning on the vertical lathe. Due to the need for clamping, it is necessary to weld the clamping ring under the head, and because of the large error of the roundness of the head, it is necessary to weld the support inside. This method of processing grooves not only has high cost, but also weld scars affect the appearance quality of the container, and it is difficult to guarantee the groove size due to vibration and roundness errors.
