Description

technical field

[0001] The invention relates to a forming method of a cylinder body, in particular to a forming method of a steel liquid accumulator cylinder body used in refrigeration system equipment. Background technique

[0002] At present, the equipment manufacturers in the refrigeration system usually adopt the stamping and stretching forming process for the machining method of the steel liquid receiver cylinder. Such as figure 1 Shown is the shape and structure of the existing steel liquid storage cylinder. The steel liquid storage cylinder has an annular weld W in the middle. Such as image 3 As shown in the existing stamping and stretching forming process, the upper and lower half of the steel liquid storage cylinder are all made of ST12 or ST14 steel plates, which have undergone material preparation, shearing, blanking, and continuous stretching for many times. At least Four times of stretching, trimming, punching, turning over holes, alignment of the two halves...
