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 work

Embodiment Construction

[0029] Figure 1~5 It is the best embodiment of the present invention. Figure 1~5 The present invention will be further explained.

[0030] A pan stretching machine includes a blank holder cylinder 12 and a stretching cylinder 1. A stretching die 6 is arranged between the blank holder cylinder 12 and the stretching cylinder 1. The stretching die 6 includes an upper blank holder 602 and a lower press The edge ring 603 and the stretching head 605, the blank holder cylinder 12 is arranged above the upper blank holder 602 to push the upper blank holder 602 down, and the stretching cylinder 1 is arranged below the stretching head 605 to push the stretching head 605 up, down The blank holder 603 is installed above an elastic support mechanism. After the upper blank holder 602 and the lower blank holder 603 are closed, the elastic support mechanism compensates the blank holder force through the deformation restoring force. The pot body stretching machine stretches the circular sheet ...

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 material stretching equipment, and in particular relates to a pot body stretching machine for stretching an electric heating pot body. Background technique [0002] The pot stretching machine is an important equipment in the production process of the electric heating pot. The pot stretching machine is mainly used for the stretching 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 side pressing cylinder, the bottom stretching cylinder and the mold installed in the middle. , The upper edge-holding cylinder presses the round steel sheet through the mold, and then the stretching cylinder stretches the round steel sheet to complete the stretching of the electric heating pot body. In the stretching process, this kind of pot stretching machin...
