Embodiment Construction

[0020] Description with reference to the accompanying drawings. The illustrated embodiment is a water storage type electric water heater housing round buckle seam device, the power of the seam seam mold is a press, the cylinder body of the middle beam cylinder 1 is fixed on the upper beam 2, and the piston rod drives the middle beam 3 to reciprocate up and down Movement, seam mold 11 is fixed below the middle beam 3. The left end of the cantilever type internal mold 9, namely the front end, is fixed on the support by the internal mold frame 10, and the right end of the internal mold 9, namely the rear end, is suspended in the air. The inner mold support cylinder is fixedly installed on the machine base below the right end of the inner mold 9, and the piston rod of the cylinder is connected with the inner mold support arm. The plate 14 to be processed is positioned and sent in. Internal mold support arm raises the rear end of supporting internal mold 9, does not draw internal ...

Abstract

The invention discloses a device for rounding and slotting a housing of a water heater, belonging to a device for seaming brim of a metal sheet for rounding and seaming bent flat plate for producing the housing of the water heater. An inner die with an axial groove on the top part is horizontally arranged on an engine base; a left holding claw and a right holding claw are located on the left and right side of the inner die; the inner surface is matched with the side of the inner die; the left holding claw and the right holding claw are driven to hold or loosen the inner die by driving power of the holding claws; a slotting die driven by power of the slotting die is arranged above the inner die; and the slotting die is matched with the inner die. The technical problems of fussy processes, high labor intensity and low production efficiency caused by rounding, folding and finally seaming in processing of the housing of the existing water heater are solved.

Description

technical field [0001] The invention belongs to a device for biting the edge of a thin metal plate, in particular to a device for wrapping and seaming a shell of a water heater. Background technique [0002] At present, when the water heater shell is processed, the production processes of rounding, folding, biting, or rounding and welding are generally used. The former has cumbersome production process, high labor intensity and low production efficiency; the latter increases welding energy consumption, and the weld needs to be reprocessed. On the front end frame of the seam seam device disclosed in China Utility Model Patent Grant No. CN2338111Y "Pipe Making Machine Seam Seam Device", a pair of cylindrical rollers and inverted conical rollers are successively set up; There are three pre-pressing rollers and two pre-pressing wheels, and there is a pre-pressing device with three rollers at the bottom of the machine base; the rear part of the device includes spring sheets, tw...
