Problems solved by technology

[0023] According to the conventional drum molding method for dryers, the drum (1) is divided into front, back, and central parts, which are made separately and then rejoined, so the manufacturing process is complicated and the number of processes increases.
[0024] In addition, the conventional drum (1), which is connected after the front, back, and center are separately produced, has a high possibility of inconsistent coaxiality of each part. In this case, when directly applied to products such as dryers, vibration and Noise affects product reliability

Embodiment Construction

[0057] In order to further understand the content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0058] image 3 It is a flow chart of the drum forming process of the present invention, Figure 4 is according to image 3 A diagram of the forming process showing the state of the drum. The drum molding process for dryer of the present invention can be roughly divided into the stage of cylindrical drum (1) molding, the stage of tube expansion molding except the two ends of cylindrical drum (1), the cylindrical drum (1) The stage of processing the bead (1b) on the expanding part (1a) of the drum, and the stage of crimping in order to stack the outer peripheries of both sides of the drum.

[0059] The forming stage of the cylindrical drum (1) is: first roll metal steel plates of materials such as stainless steel into a cylindrical shape, and then we...

Abstract

The invention supplies rolling barrel molding method of a dryer that has no mould separating trace. The proper circle rate of the entire rolling barrel is improved. And the inside scuffing of the rolling barrel would be avoided in the molding process. The molding method includes the following steps: the molding stage of the rolling barrel; two ends of the rolling barrel expanding pipe and molding stage, processing and layering at the center of the rolling barrel stage, and bending collapsing beading process stage. The dryer rolling barrel includes column barrel, opening section, layering section and beading section.

Description

technical field [0001] The invention belongs to a drum for a dryer, in particular to a molding method for a clothes dryer drum and a drum structure rolled according to it. Background technique [0002] In general, a dryer is a device that supplies hot air generated by an electric heater or a gas device to drying objects such as clothes in a drum to dry them. Recently, its demand is an increasing trend. [0003] figure 1 Showing the structure of a conventional dryer, it is an exploded perspective view of its important parts. [0004] Such as figure 1 As shown, a drum (1) is provided inside the casing (not shown) constituting the appearance of the dryer. The drum (1) is cylindrical as a whole, and forms its front and rear openings, and is formed with a belt groove (2) around which a belt (not shown) driven by another driving source is wound along its outer peripheral surface. ). [0005] A space for drying is formed inside the drum (1), that is, a drying chamber (5), and...
