Trimming machine for producing inner drum of washing machine

Abstract

The invention discloses a trimming machine for producing an inner drum of a washing machine. The trimming machine comprises a rack, wherein a main shaft is rotatablely arranged on the rack, is in transmission connection with the motor and is connected with a tensioning die mechanism; the upper part of the rack is provided with a pressing die and a rolling die for squeezing the upper edge of the inner drum of the washing machine; the lower part of the rack is provided with a trimming die and a rounding die for squeezing the lower edge of the inner drum of the washing machine; the rack is provided with an ejection die for further squeezing the lower edge of the inner drum of the washing machine. According to the trimming machine for producing the inner drum of the washing machine, the ejection die is additionally arranged, so that the flanging angle can be greater than 90 degrees through further flanging after the flanging of the trimming die is finished, the damage of workpieces during flanging of the rounding die caused by insufficient angle is reduced, the qualification rate of the products is high and the economic loss is reduced.

Description

technical field [0001] The invention relates to a hemming machine, in particular to a hemming machine for washing machine inner barrel production. Background technique [0002] The production of the inner barrel of the washing machine is generally to cut the metal sheet into the required width and length according to the requirements, and then send it into the mold on the punching machine through the feeder for punching. The riveting machine performs buckle riveting, and the riveted workpiece is rolled in the next process. After the rolling is finished, the workpiece is placed in the expanding mold of the rolling machine and then rolled. At present, the lower side of the inner tub of the washing machine is usually folded at a certain angle by the hemming die of the hemming machine, and then folded to a side close to 180° by the rounding die. When the process is further folded, it is easy to damage the workpiece, causing the product to be unqualified, thereby making the prod...
