Embodiment Construction

[0018] Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. figure 2 is an appearance view of an ice-making drum according to an embodiment of the present invention; image 3 is a manufacturing engineering drawing of an embodiment of the present invention; Figure 4 is a cross-sectional view of an ice-making drum made according to the present invention.

[0019] Such as image 3 As shown, the manufacturing method of the ice-making roller of the present invention includes: cutting the aluminum round rod 10 into specifications for release, and preparing a stage of forming material blocks 11 with a certain size (S1). Preferably, before forging, the formed material block 11 obtained above is pre-treated, that is, annealed heat treatment is performed to remove residual stress inside the material, or to improve the softness of the material, and to apply a lubricant on the surface.

[0020] Next, the molding material ...

Abstract

The invention relates to a manufacturing method of an ice-making roller and an ice-making roller. The ice-making roller is easy to produce, has an excellent cooling performance, and is durable. The manufacturing method comprises the following steps: (S1) cutting an aluminum round rod (10) to prepare a moulded material block (11), forging the moulded material block (11), opening one end of a cylindrical edge (13) as an open part (14), blocking the other end by an end wall (15), and forming a support shaft (16), which protrudes outwards from the center of the end wall (15); (S2) forming a hollowcylindrical semi-finished product (12) of a shaft support part (17) on the inner side of the center of the end wall (15); (S3) shrinking the edge (13) of the open part (14) of the hollow cylindricalsemi-finished product (12), and forming a roller semi-finished product (21) with a neck part (25) with a shrunk shoulder (22) and a through hole (24); and (S4) mechanically processing the surface of the roller semi-finished product (21), and processing the surface by anodic oxidation to form an oxidized coating (25).

Description

technical field [0001] The present invention relates to a manufacturing method of an ice-making roller and the ice-making roller, in particular, a novel ice-making roller manufacturing method and the ice-making roller which are easy to manufacture and have excellent cooling performance and excellent durability. Background technique [0002] In the ice machine having the ice making drum, the ice making drum having the evaporator of the refrigerating appliance built in is partially submerged on the water supply tank, and is rotatable. The water in the water supply tank sticks to the surface of the ice-making drum, and when the ice-making drum rotates, the water on the surface of the ice-making drum cooled by the internal freezer freezes, making it close to the cutter provided on the other side of the ice-making drum, The ice layer that freezes to an appropriate thickness is detached from the ice-making drum and collected in the collection tank arranged at the lower part to mak...
