A labyrinth forming device

Abstract

The invention discloses a novel labyrinth forming device which comprises a rolling mill and a bending machine. The rolling mill comprises a rolling inlet assembly, a rolling mill base, a rolling outlet assembly, a fixed gearbox assembly, a rolling wheel assembly, a power assembly and a rolling mill width adjusting assembly. The bending machine comprises a conveying assembly, a bending machine base, a bending machine width adjusting assembly, lateral positioning assemblies, a movable bending assembly, a fixed bending assembly, upper molds and turnover molds. The conveying assembly is connected with the rolling outlet assembly. According to the novel labyrinth forming device, rolling and bending are combined, so that the size error of labyrinth forming is reduced by 4 times, the angle error of labyrinth forming is reduced by 3 times, and the requirement for the installation size of an existing refrigerator is met.

Description

technical field [0001] The invention relates to the field of refrigerator manufacture, in particular to a labyrinth forming device. Background technique [0002] Existing refrigerator shell labyrinth all adopts rolling mill one-time rolling forming, as Figure 5 As shown, the error of dimensions A and B is ±0.5mm, and the error of angle is ±2 degrees. Due to the large error of size and angle and instability, it will affect the assembly accuracy of the refrigerator shell and inner tank, resulting in material leakage during foaming and affecting Product size and appearance are very critical quality factors in the refrigerator manufacturing process. Contents of the invention [0003] The invention provides a labyrinth forming device, which is combined and formed by rolling and bending, and the labyrinth of the refrigerator shell after forming has small error and greatly improved product quality. [0004] The technical scheme adopted in the present invention is: [0005] A l...
