A pot body stretching machine

Abstract

The invention discloses a pot stretcher, and belongs to the technical field of plate stretching equipment. The pot stretcher comprises a blank pressing cylinder (12) and a stretching cylinder (1), wherein a stretching mold (6) is arranged between the blank pressing cylinder (12) and the stretching cylinder (1); the stretching mold (6) comprises an upper blank pressing ring (602), a lower blank pressing ring (603) and a stretching head (605); the blank pressing cylinder (12) is arranged above the upper blank pressing ring (602) to push the upper blank pressing ring (602) to descend; the stretching cylinder (1) is arranged below the stretching head (605) to push the stretching head (605) to ascend. The pot stretcher is characterized in that the lower blank pressing ring (603) is mounted above an elastic support mechanism; after the upper blank pressing ring (602) is molded with the lower blank pressing ring (603), blank pressing force is compensated by the elastic support mechanism through deformation resilience. As the elastic support mechanism is adopted in the pot stretcher to compensate the blank pressing force, the pot stretcher has the advantages of being stable in compensation force and convenient to adjust.

Description

technical field [0001] A pot body stretching machine belongs to the technical field of sheet metal stretching equipment, and in particular relates to a pot body stretching machine used for stretching the pot body of an electric heating pot. Background technique [0002] The pot body stretching machine is an important equipment in the production process of the electric heating pot, and the pot body stretching machine is mainly used for stretching the pot body of the electric heating pot. Most of the existing pot body stretching machines are double-action hydraulic pot body stretching machines. This kind of pot body stretching machine mainly includes the upper edge-pressing oil cylinder, the bottom stretching oil cylinder and the mold installed in the middle. , the upper edge-pressing oil cylinder presses the circular steel sheet through the mold, and then the stretching oil cylinder stretches the circular steel sheet to complete the stretching of the electric heating pot body...

AI Technical Summary

Problems solved by technology

During the stretching process, this kind of pot body stretching machine mainly relies on the deformation of the column and other materials to compensate the blank-holding force of the stretching, but the mechanical deformation is greatly affected by the environment and materials, so it needs to be continuously stretched during the stretching process. Adjust the position of the fixed workbench to stretch out the qualified electric heating pot body. Since the fixed workbench is installed on the column, it is difficult to ensure that the adjustments of the four columns are completely consistent during the adjustment process, so it is easy to cause insufficient blank-holding force. The problem of balance affects the drawing quality and drawing efficiency of the pot body

The working stability of this double-action hydraulic pot stretching machine is relatively poor, and the adjustment is troublesome, and the processing efficiency is low
